DETAILED DESCRIPTION

[0028] In order to better understand the purpose, structure and function of the present invention, a built-in gas cooker of the present invention is further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the embedded gas cooker of the present invention comprises a bottom shell and a burner head 3, the bottom shell comprises a panel 1 and a side panel 2 arranged on the periphery of the panel 1, the burner head 3 is fixed on the panel 1, and the burner head 3 is connected to an ejection pipe for conveying gas, and the panel 1 is also provided with an air supply device for supplying air to the ejection port of the ejection pipe, so that the gas and air are fully premixed. By providing the air supply device, the air is effectively transported to the ejection port of the ejection pipe, and the amount of air ejected by the burner is increased, thereby achieving a better primary premixing effect and making the gas burn more fully.

[0030] like Figure 2 As shown, two stove openings 11 are provided on the panel 1, and burners 3 are respectively arranged in the two stove openings 11. The two burners 3 are respectively connected to the ejection pipes, and the ejection pipes are connected to the main air inlet pipe 32. The air supply device is fixed on the rotating mechanism 8, and the rotating mechanism 8 drives the air outlet end of the air supply device to align with the ejection ports of the ejection pipes on both sides, so that when one of the burners 3 is used, air is blown to the ejection pipe in use through the air supply device to improve the premixing effect.

[0031] like Figure 5 As shown, the air supply device is a blower 5, which is electrically connected to a controller 13, and the controller 13 is fixed on the panel 1. The blower 5 includes a shell 51 and rotatable blades 52 arranged in the shell 51, and the bottom surface of the shell 51 is fixed on the rotating mechanism 8.

[0032] The rotating mechanism 8 includes a rotating shaft 83 connected to the bottom surface of the shell 51 , the end of the rotating shaft 83 is fixed to the driving shaft of the rotating motor 82 , the rotating motor 82 is fixed in the protective shell 81 , and the driving shaft of the rotating motor 82 passes through the top of the protective shell 81 and is connected to the rotating shaft 83 .

[0033] In actual use, two stove heads 3 may be used simultaneously. To expand the application range of the air supply device, a translation mechanism 6 is further provided between the two stove openings 11 , and the rotating mechanism 8 is fixed on the translation mechanism 6 .

[0034] like Figure 3 As shown, the translation mechanism 6 includes a lead screw 63 and a slider seat 62. A groove body for accommodating the lead screw 63 is arranged on the top surface of the slider seat 62. One end of the lead screw 63 is rotatably fixed on the slider seat 62. The other end of the lead screw 63 passes through the side wall of the slider seat 62 and is fixed on the driving shaft of the translation motor 61. The translation motor 61 is fixed on the panel 1. A slider 64 is screwed on the lead screw 63. The side wall of the slider 64 is arranged on a slide groove matching the slider seat 62. The rotating mechanism 8 is fixed on the slider 64.

[0035] In addition, other linear translation mechanisms 6 may be used to achieve translation of the air supply device, such as a gear rack linear translation mechanism, a pneumatic telescopic rod or a hydraulic telescopic rod, etc., which will not be described in detail here.

[0036] In order to determine the use status of the burner head 3, a temperature sensor is provided on the burner head 3, and the temperature sensor is electrically connected to the controller 13. When the controller 13 determines that the ignition is on one side, the controller 13 sends a control translation signal to the translation motor 61 to move the air supply device toward the injection port of the injection pipe. When it moves to the set position, the controller 13 sends a rotation signal to the rotation motor 82 to align the air outlet of the air supply device with the injection port of the burner head 3 in use, thereby increasing the primary air coefficient, enhancing the premixing effect of the gas and air, and making the gas burn more fully.

[0037] When the controller 13 determines that the ignition is on both sides, the controller 13 sends a control translation signal to the translation motor 61 to move the air supply device toward the injection port of the injection pipe. When it moves to the set position, in order to make the air blown by the blower 5 enter the injection ports on both sides respectively, as shown in FIG. Figure 3 As shown, it also includes an air guide mechanism, which is arranged on the side plate 2 close to the injection pipe side. The wind blown by the blower 5 enters the injection ports on both sides through the air guide mechanism.

[0038] The air guide mechanism includes a symmetrically arranged air guide plate 7, one end of which is fixed on the side plate 2 close to the ejector tube, and the other end of the air guide plate 7 approaches the furnace head 3 along the axial direction of the ejector tube. The air blown by the blower 5 is reflected by the air guide plate 7 and enters the ejector ports on both sides.

[0039] The blower 5 is electrically connected to the controller 13 , and the air supply strength of the blower 5 can also be controlled by adjusting the rotation speed of the blower 5 .

[0040] In order to increase the amount of air entering the bottom shell, the side panels 2 include multiple pieces, gaps for air to enter are formed between the multiple side panels 2, and the side panels 2 are detachably connected to the panel 1.

The panel 1 is provided with a fixing hole, and the plug plate 21 is fixed to the panel 1 by a fastener. By setting the long strip adjustment hole 211, it is convenient to adjust the outer frame size of the bottom shell, which is conducive to the air entering the bottom shell and ensuring that the air volume in the bottom shell is sufficient. The blower 5 is conducive to improving the primary air coefficient and making the gas and air premixed better; on the other hand, the use of the gas stove for different opening sizes in the user's home reduces the probability that the gas stove purchased at home cannot be put in and cannot be used, and avoids the problem of re-opening the hole. The fastener can be a screw, a rivet, etc.

[0042] like Figure 7 As shown, the slot is provided by a pair of L-shaped mounting plates 4, one end of the two mounting plates 4 is fixed to the bottom surface of the panel 1, and the other ends are arranged close to each other, the plug-in plate 21 is inserted between the two mounting plates 4, and mounting holes 42 are respectively arranged on the mounting plates 4 and the panel 1, and the mounting plates 4 are fixed to the panel 1 by fasteners.

[0043] Guide plates 212 bent downward are respectively provided at both ends of the plug plate 21 , and guide grooves 41 cooperating with the guide plates 212 are provided on the mounting plate 4 . The guide plates 212 are arranged along the pulling direction of the plug plate 21 .

[0044] The burner head 3 includes a fire cover 31 arranged at the stove opening 11 of the panel 1, and the bottom surface of the fire cover 31 is connected to the ejection pipe. The ejection pipe includes an inner ring air inlet pipe 33 and an outer ring air inlet pipe 34 connected to the fire cover 31. A nozzle 36 connected to a valve body 35 is provided at the entrance of the inner ring air inlet pipe 33 and the outer ring air inlet pipe 34. The air inlet end of the valve body 35 is connected to the main air inlet pipe 32. An air inlet pipe hole for the main air inlet pipe 32 to pass through is provided on the plug plate 21 below the main air inlet pipe 32, and the main air inlet pipe 32 is connected to the air source.

[0045] A battery box hole 12 for accommodating a battery box is also provided on the panel 1 away from the main air inlet pipe 32 , and a through hole for accommodating a battery box is provided on the side panel 2 below the battery box hole 12 .

[0046] The embedded gas stove improves the primary air coefficient of the gas stove burner, effectively improves the thermal efficiency of the gas stove, and reduces the emission of harmful gases. The bottom shell is designed as an open structure with adjustable size, which is conducive to the air entering the bottom shell, ensuring that the air volume in the bottom shell is sufficient, and the blower 5 is conducive to improving the primary air coefficient, so that the gas and air are better premixed; on the other hand, the gas stove can be used for different hole sizes in the user's home, reducing the probability that the gas stove cannot be put in and cannot be used after purchase, and avoiding the problem of re-drilling holes.
