Description:

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a smoke guiding machine, and more particularly to a smoke guiding machine utilizing a configuration whereby air walls are disposed around a gas stove. The smoke guiding machine of the present invention is capable of guiding smoke produced while cooking to an entrance of a smoke exhaust, and therefrom discharging the smoke outdoors and omnidirectionally isolating the smoke.

(b) Description of the Prior Art

A common kitchen gas stove is provided with a smoke exhaust configured above the kitchen gas stove, and which is utilized for discharging smoke to an upper portion of the kitchen gas stove. However, because a specific distance exists between the smoke exhaust and the gas stove, thus suction range of the smoke exhaust cannot be effectively realized, resulting in a portion of remaining smoke still contaminating kitchen utensils, which can also be hazardous to lungs when inhaled.

Referring to Taiwan patent No. 383088, entitled air Forwarding Device for Assisting Suction and Discharge of Smoke Exhaust (hereinafter referred to as the first cited invention), and Taiwan patent No. 479789, entitled Compelling Smoke Guiding Machine (hereinafter referred to as the second cited invention), wherein a positioning pole 3 is necessarily used for pivotally disposing a air forwarding device 2 to a smoke exhaust 11 in the first cited invention. However, a gas stove 12 as used in a household comes in distinct dimensions, and, thus, the gas stove 12 having larger dimensions is inapplicable for use in the first cited invention. In addition, the air forwarding device 2 cannot be attached around the gas stove 12 so as to form an integral unit with the gas stove 12.

A compelling smoke guiding machine A disclosed in the second cited invention has a relatively complicated structure. The compelling smoke guiding machine A comprises structural configurations including a secondary arm 2, a pivotal arm 30, an end cover 40, a transmission axis cover 50, an interconnecting pole 60, a cover assembly 70, a blower 80 and a blower fan axis 90. Furthermore, the smoke guiding machine A can only be disposed in front of a gas stove 11, and thus fails to function as an omnidirectional smoke-isolating device. Above all, the compelling smoke guiding machine A cannot be attached around the gas stove 11 so as to form an integral unit therewith.

The air forwarding device 2 and the compelling smoke guiding machine of the first and second cited inventions respectively are assembled using screw bolts and are thus labor intensive. Furthermore, because the structural configurations of the two cited inventions have invariable dimensions, thus the structural configurations cannot be integrally combined with a conventional gas stove unit having distinct dimensions. In addition, such prior structural configurations are inadaptable to different heights between the smoke exhaust and the gas stove in various households, and are unable to effectuate adjusting appropriate air speeds for forwarding and facilitating discharge of the smoke produced.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide a smoke guiding machine, wherein left and right member devices are joined to a front member device by means of terminals and fixing pins inserting into terminal ports and pin holes of the front member device respectively, and the terminals being inserted into the terminal ports can thereby actuate conductive flow of electricity. Furthermore, inserting pins configured on left and right member device casings of the front member device are respectively fixedly inserted into inserting pin holes defined in left and right casing covers respectively, thus realizing a configuration that allows lifting of the casing covers when required, and which thus facilitates an extremely convenient and applicable jointing method for assembly of the smoke guiding machine.

Another object of the present invention is to provide a smoke guiding machine, wherein a button clasp is configured in an indentation of each of the member device casings of the left and right member devices. Furthermore, a clasp hook of each of the button clasps respectively hook into a clasp hole of the respective member device casing of the front member device, thereby fixing position of the left and right member devices thereat. Upon wishing to separate the left and right member devices from the front member device, the button clasps are pressed to effectuate disengagement of the left and right member devices from the front member device.

Yet another object of the present invention is to provide a smoke guiding machine, wherein screws ordinarily screw down the left and right casing covers configured on an upper portion of the left and right member device casings on two sides of the front member device respectively, thus the left and right casing covers are incapable of being opened, and prevents children from arbitrarily opening the casing covers. When foreign bodies, such as vegetable residue, and so on, are accidentally dropped into the member device casings, the screws can be unscrewed thereby allowing opening up of the casing covers to facilitate extracting the vegetable residue and foreign bodies.

To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, the smoke guiding machine of the present invention comprises a front member device 1, a left member device 2 and a right member device 3 disposed at a front side, a left side and a right side of a gas stove 10 respectively, and which are integrally formed with a gas stove 10 (see FIG. 7).

The front member device 1 comprises a left casing 11, a right casing 12, a left casing cover 110 and a right casing cover 120, and an air-speed tuner 13 fastened and connected between the left casing cover 110 and the right casing cover 120. Air inlet openings 1101 and 1201 are disposed on front sides of the left casing cover 110 and the right casing cover 120 respectively, and are provided with squirrel-cages 111, 121 and motors 112, 122 disposed interior thereof respectively, as depicted in FIG.6. The squirrel-cages 111 and 121 are axially connected with axes of the motors 112 and 122 respectively, which thereby allow the motors 112 and 122 to drive and rotate the squirrel-cages 111 and 121 respectively. Apart from appropriately adjusting air speed (because height of smoke exhausts in individual households are different, and therefore air speeds required also varies), the air-speed tuner 13 also serves as a power switch.

The left and right member devices 2 and 3 are identical structures disposed at left and right sides of the front member device 1 respectively. FIG. 1 only shows an exploded view of the right member device 3. The left and right member devices 2 and 3 comprise member device casings 21 and 31 and casing covers 22 and 32 respectively. Referring to FIG. 6, the member device casings 21 and 31 are provided with squirrel-cages 211 and 311, and motors 212 and 312 respectively. Squirrel-cages 211 and 311 are axially connected with axes of the motors 212 and 312 respectively, which thereby allow the motors 212 and 312 to drive and rotate the squirrel-cages 211 and 311 respectively. Air inlet openings 321 are disposed in the casing cover 32 (air inlet openings being similarly disposed in the casing cover 22 of the right member device). The member device casing 31 is provided with a power supply connector 313 at one side thereof respectively, as depicted in FIG.5 (the member device casing 21 being similarly provided with a power supply connector at one side thereof). The smoke guiding machine of the present invention is further improved in that:

Referring to FIG. 1, a same jointing method is employed for joining the left member device 2 or the right member device 3 to the front member device 1, thus, taking the right member device 3 and the front member device 1 as an example, wherein, one end of the member device casing 31 of the right member device 3 is provided with a terminal 314 and three fixing pins 315 (see FIG. 1A), and one end of the right member device casing 12 of the front member device 1 is provided with a terminal port 14 and three pin holes 15 (see FIG. 1B), which can respectively provide for the terminals 314 and the three fixing pins 315 of the right member device 3 to fixedly lodge thereinto respectively. The terminals 314 upon being inserted into the terminal port 14 can thereby actuate conductive flow of electricity. Referring to FIGS. 2 and 3, which show a button clasp 33 configured in an indentation 317 of one end of the member device casing 31 of the right member device 3. An inverted hook 331 respectively configured on an upper and a lower end of the button clasp 33 hook onto respective protruding pieces 318 of inner edges of the indentation 317 of the member device casing 31. A clasp post 332 at one end of the button clasp 33 then extends into a post hole 319 defined in a side of the indentation 317 of the member device casing 31. A spring 34 is disposed on a clasping pin 320 of an inner side of the member device casing 31, and another end of the spring 34 abuts upon a side edge of the button clasp 33. Furthermore, another end of the button clasp 33 is provided with a clasp hook 333. The clasp hook 333 hooks into a clasp hole 124 of the right member device casing 12 of the front member device 1 (see FIG. 3), thus enabling the front member device 1 to fix position of the right member device 3. Upon wishing to disconnect the front member device 1 from the right member device 3, the button clasp 33 must be pressed, whereat the button clasp 33 inwardly squeezes the spring 34, and the clasp hook 333 thus disengages from clasping within the clasp hole 124 of the right member device casing 12, and the right member device thereby separates from the front member device.

Furthermore, a same jointing method is employed for joining the left casing cover 110 and the right casing cover 120 of the front member device 1 to the front member device 1, thus, taking the right casing cover 120 as an example, as depicted in FIG. 4, two oppositely directed inserting pins 123 are configured on a top edge of an inner side of the right member device casing 12 of the front member device 1 (see FIG. 4D), and inserting pin holes 1202 are respectively defined in two ends of the right casing cover 120, and which provide for the inserting pins 123 to respectively insert thereinto and thereby fix position thereat, thus realizing a configuration that enables joining of the right casing cover 120 to the right member device casing 12 and for lifting of the right casing cover 120 when required. A screw 16 upwardly screws into a bottom end of a front edge of the right casing cover 120 through a base of the right member device casing 12, thereby solidly screwing down the right casing cover 120 to the right member device casing 12, and thus preventing children from arbitrarily opening the right casing cover 120. When foreign bodies, such as vegetable residue, and so on, are accidentally dropped into the right member device casing 12 through the air inlet openings 1201 of the right casing cover 120, a user can unscrew the screw 16, and lift up the right casing cover 120, thereby facilitating extracting the vegetable residue and foreign bodies.

Furthermore, a same jointing method is employed for joining the member device casings 21, 31 of the left and the right member devices 2, 3 respectively to the casing covers 22 and 32 respectively, thus, taking the right member device casing 3 as an example, as depicted in FIG. 5, wherein a top end of a rear side of the casing cover 32 is provided with three bolt holes 322, which provide for bolts to bolt down into the member device casing 31. A bottom portion of a front edge of the casing cover 32 is provided with three cards 323, and, a bottom portion of a front edge of the member device casing 31 is correspondingly provided with three clasp holes 316, which provide for the cards 323 to fix position thereinto.

In conclusion, according to the aforementioned, the present invention can be installed around the gas stove so as to form an integral part of the gas stove, moreover, the air-speed tuner 13 is utilized to adjust appropriate air speeds desired according to different heights of smoke exhausts in various households.

It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
