Technical Field

[0001] This utility model relates to a gas cooking machine. Background Technology

[0002] To achieve automatic cooking, many manufacturers have developed electric smart home cooking machines. There are also some commercial gas-fired automatic cooking machines on the market. Currently, automatic cooking machines have some problems. Most electric smart home cooking machines on the market have issues with low power and slow heating. Furthermore, most electric smart home cooking machines on the market are countertop models, installed on kitchen countertops, which take up space and are difficult to clean. Commercial gas-fired cooking machines on the market are also mostly countertop models, which not only occupy countertop space but also result in greater heat radiation during cooking, making them difficult to clean and less intelligent. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of low power and slow heating caused by the use of electric energy in the prior art, and to provide a gas cooking machine.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This utility model provides a gas cooking machine, which includes a panel, a base, a burner, and a pot body. The base is located below the panel and connected to the panel, and a receiving cavity is formed between the base and the panel. The burner is disposed in the receiving cavity. The panel has a placement opening. The pot body passes through the placement opening and extends into the receiving cavity. The burner is located below the pot body for heating the pot body.

[0006] In this design, the gas cooking appliance uses a gas burner instead of an electric heater, achieving high-load, high-efficiency cooking. Furthermore, by connecting the panel and base to form a cavity, both the burner and the pot are placed within this cavity, effectively embedding the gas cooking appliance's combustion and cooking systems beneath the panel. Therefore, this arrangement saves countertop space, makes cleaning the appliance easier, and reduces heat radiation during cooking because the burner is housed within the cavity.

[0007] Preferably, the gas cooking appliance further includes a pot cover, the top of which is attached to the panel, the bottom of which extends into the receiving cavity through the placement opening, the burner is disposed inside the pot cover, the pot cover surrounds the pot body, and the pot cover and the pot body are fitted with a clearance to form a hot air passage.

[0008] In this design, by setting a pot cover to fully enclose the burner and pot body, when the flame directly heats the pot body, the high-temperature flue gas can be discharged into the atmosphere along the gap between the pot cover and the pot body, thus forming a hot air passage. Compared to the past, where the high-temperature flue gas from the burner generally only exchanges heat with the vertical edge near the bottom of the cooking appliance, this design increases the heat exchange area between the high-temperature flue gas and the side wall of the pot body, thereby increasing the heat absorption of the side wall and improving the heat exchange rate. In addition, in the past, the high-temperature flue gas from the burner encountered less resistance and could be discharged smoothly, resulting in a faster flow rate. However, the structure of this design requires the high-temperature flue gas to travel through a longer passage and undergo a change of direction, which reduces the flow rate of the high-temperature flue gas and increases the residence time of the high-temperature flue gas on the side of the pot body, thereby improving the heat exchange efficiency between the high-temperature flue gas and the side wall of the pot body.

[0009] Preferably, the pot cover includes an upper pot cover, the top of which is connected to the panel and extends into the receiving cavity. The upper pot cover surrounds the pot body and forms a gap. The top of the upper pot cover has an opening, and the bottom of the upper pot cover is provided with a gas flow hole. The opening, the gas flow hole, and the gap form the hot air passage.

[0010] In this solution, the upper part of the pot cover can be easily installed by setting the upper pot cover, and the hot air passage formed by the top opening, bottom gas flow hole and gap of the upper pot cover further improves the heat exchange efficiency between the high temperature flue gas and the side wall of the pot body.

[0011] Preferably, the outer surface of the pot body has multiple outwardly protruding limiting structures, and the multiple limiting structures abut against the upper pot cover.

[0012] In this solution, by setting a limiting structure, the rotation of the pot can be restricted to prevent slippage during cooking and thus avoid affecting the cooking effect.

[0013] Preferably, the pot cover further includes a lower pot cover, the top of which is connected to the upper pot cover, the bottom of which is connected to the base plate, the burner is disposed inside the lower pot cover, and air circulation holes are provided on the side of the lower pot cover.

[0014] In this design, the lower part of the pot cover can be easily installed by setting up a lower pot cover, and cold air is introduced through the air circulation holes of the lower pot cover. The cold air is used for combustion, and the high-temperature flue gas generated by combustion is input into the hot gas passage.

[0015] Preferably, the lower pot cover and the upper pot cover are detachably connected; and / or, the lower pot cover and the base are detachably connected.

[0016] In this solution, the detachable connection between the upper and lower pot covers, as well as between the lower pot cover and the base, further facilitates the installation and replacement of the pot covers, improving the installation efficiency of the cooking machine.

[0017] Preferably, the pot body includes a pot body and a stirring assembly. The stirring assembly includes a lid, stirring blades, a driving device, and an operating handle. The pot body extends into the receiving cavity through the placement opening. The lid covers the pot body. The stirring blades are located inside the pot body. The driving device passes through the lid and is connected to the stirring blades. The operating handle is electrically connected to the driving device.

[0018] In this solution, by setting up a stirring assembly with a drive device and stirring blades, the blades can rotate under the drive device, thereby stirring the ingredients in the pot and achieving automatic cooking.

[0019] Preferably, the operating handle includes a Bluetooth module, a battery, and a handle housing. The handle housing is connected to the driving device, and both the battery and the Bluetooth module are disposed inside the handle housing. The Bluetooth module is electrically connected to the battery and the driving device.

[0020] In this solution, by setting up a Bluetooth module, the frequency, speed, and direction of the drive device can be controlled to operate the stirring operation.

[0021] Preferably, the gas cooking appliance further includes a valve assembly, one end of which is connected to the burner, and the other end of which passes through the chassis and protrudes outside the chassis.

[0022] In this solution, by setting up a pipe valve assembly, the gas flow can be adjusted, thereby controlling the flame size to meet cooking needs.

[0023] Preferably, the gas cooking appliance further includes a control board disposed on the panel and electrically connected to the burner and / or the pot body; and / or, the gas cooking appliance further includes a temperature measuring component connected to the burner and abutting against the bottom of the pot body.

[0024] In this solution, the operation of the cooking machine can be controlled by a control panel, and the temperature measuring device can more accurately reflect the temperature of the bottom of the pot, thereby improving the convenience and accuracy of the cooking machine operation and realizing intelligent control of the cooking machine.

[0025] The positive and progressive effects of this utility model are as follows:

[0026] This utility model discloses a gas-fired cooking appliance that achieves high-load, high-efficiency cooking by using a gas burner instead of an electric heater. Furthermore, by connecting the panel and base to form a receiving cavity, both the burner and the pot are placed within this cavity, allowing the combustion and cooking systems of the gas-fired cooking appliance to be embedded beneath the panel. Therefore, this arrangement saves countertop space, makes cleaning the cooking appliance easier, and reduces heat radiation during cooking because the burner is placed inside the receiving cavity.

[0078] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0079] This embodiment provides a gas cooking appliance, such as... Figure 1 and Figure 2 As shown, it includes a panel 1, a base 2, a burner 3, and a pot body 4. The base 2 is located below and connected to the panel 1, and a receiving cavity 5 is formed between the base 2 and the panel 1. The burner 3 is disposed within the receiving cavity 5. Figure 2 and Figure 3 As shown, panel 1 has a placement opening 11, pot body 4 passes through placement opening 11 and extends into receiving cavity 5, and burner 3 is located below pot body 4 for heating pot body 4.

[0080] Therefore, the electric power of an electric heater is generally around 2KW, while the gas burner 3 can reach around 5KW. Using the gas burner 3 to replace the electric heater achieves high-load, high-efficiency cooking. Furthermore, by connecting the panel 1 and the base 2 to form a receiving cavity 5, both the burner 3 and the pot body 4 are placed within the receiving cavity 5, allowing the combustion and cooking systems of the gas cooking machine 100 to be embedded below the panel 1. Therefore, this arrangement saves countertop space and makes cleaning the cooking machine easier. Since the burner 3 is placed inside the receiving cavity 5, heat radiation during cooking is also reduced, achieving flameless heat radiation.

[0081] In this embodiment, since both the combustion system and the cooking system of the cooking machine are embedded under the panel 1, the periphery of the panel 1 can be extended beyond the edge of the base 2 to form a planar surface that can be laid. This planar surface can then be laid on an open work surface, allowing the entire cooking machine to be embedded under the work surface, thus maximizing the saving of upper work surface space. In other embodiments, embedding methods deemed suitable by those skilled in the art can also be used.

[0082] Specifically, such as Figure 2As shown, the gas cooking appliance 100 also includes a pot cover 6, which is a cylinder with an upper diameter smaller than its lower half-diameter. The top edge of the pot cover 6 has a horizontally extending hook part 612, which is attached to the panel 1. The bottom of the pot cover 6 extends through the placement opening 11 on the panel 1 and into the receiving cavity 5 between the base plate 2 and the panel 1, and the bottom of the pot cover 6 is connected to the base plate 2. The burner 3 is placed in the lower part of the pot cover 6. The upper part of the pot cover 6 surrounds the pot body 4 and is fitted with a gap, that is, a gap is formed between the inner wall of the upper part of the pot cover 6 and the side wall of the pot body 4. This gap is a hot air passage, which is used to allow the hot air generated by the burner 3 to pass through the bottom of the pot body 4 to the side wall and then be discharged from the cooking appliance.

[0083] Therefore, by setting the pot cover 6 to fully surround the burner 3 and the pot body 4, when the flame directly heats the pot body 4, the high-temperature flue gas can be discharged into the atmosphere along the gap between the pot cover 6 and the pot body 4, thus forming a hot gas passage. Figure 2 As shown, the high-temperature flue gas generated by combustion is discharged from the cooker through the hot air passage between the upper part of the pot cover 6 and the pot body 4. The dotted line in the figure shows the flow path of the hot air. Compared with the past, where the high-temperature flue gas from the burner 3 generally only exchanges heat with the vertical edge near the bottom of the cooker, the hot air passage of this design can increase the heat exchange area between the high-temperature flue gas and the side wall of the pot body 4, thereby increasing the heat absorption of the side wall and improving the heat exchange rate. In addition, in the past, the high-temperature flue gas from the burner 3 encountered less resistance and could be discharged smoothly, resulting in a faster flow rate. However, the structure of this design requires the high-temperature flue gas to pass through a longer passage and undergo a change of direction, which reduces the flow rate of the high-temperature flue gas and increases the residence time of the high-temperature flue gas on the side of the pot body 4, thereby improving the heat exchange efficiency between the high-temperature flue gas and the side wall of the pot body 4.

[0084] The pot cover 6 can be formed in one piece or assembled from multiple components. In this embodiment, such as... Figures 4-6 As shown, the pot cover 6 is divided into an upper pot cover 61 and a lower pot cover 62. The upper part of the pot cover 6 is the upper pot cover 61, and the lower part of the pot cover 6 is the lower pot cover 62. Both the upper pot cover 61 and the lower pot cover 62 are cylindrical structures, and the diameter of the upper pot cover 61 is smaller than the diameter of the lower pot cover 62. Figure 4 As shown, the top edge of the upper pot cover 61 has a horizontally extending hook portion 612, which rests on the panel 1. The upper pot cover 61 extends into the receiving cavity 5, surrounds the pot body 4, and forms a gap between the inner wall of the upper pot cover 61 and the side wall of the pot body 4. The top of the upper pot cover 61 has an opening, and the bottom of the upper pot cover 61 has a gas flow hole 611. Therefore, the hot air passage between the pot cover 6 and the pot body 4 can be further refined into a structure consisting of the opening of the upper pot cover 61, the gas flow hole 611 of the upper pot cover 61, and the gap between the inner wall of the upper pot cover 61 and the side wall of the pot body 4.

[0085] Specifically, the top of the lower pot cover 62 is connected to the bottom of the upper pot cover 61, and the bottom of the lower pot cover 62 is connected to the base plate 2. The lower pot cover 62 has a recessed portion 622, which is a recessed cavity formed by extending from the top edge of the lower pot cover 62 from the inside to the bottom. The burner 3 is disposed in the recessed portion 622 of the lower pot cover 62. Figure 5 and Figure 6 As shown, the side of the lower pot cover 62 is provided with an air circulation hole 621, such as... Figure 7 As shown, heat dissipation and ventilation slots 21 are opened on the bottom wall and side wall of the chassis 2.

[0086] Thus, through the fully enclosed combustion chamber structure of the upper pot cover 61 and the lower pot cover 62, the hot and cold air are separated. When the burner 3 is burning, cold air is drawn in from the chassis 2 through the air flow hole 621 of the lower pot cover 62. Part of the cold air is used as primary air for combustion, and part of the cold air is used as secondary air for combustion.

[0087] Specifically, such as Figure 8 As shown, the outer surface of the pot body 4 has multiple outwardly protruding limiting structures 41, and the multiple limiting structures 41 all abut against the upper pot cover 61.

[0088] Therefore, by setting the limiting structure 41, the rotation of the pot body 4 can be restricted to prevent slippage during cooking and affect the cooking effect. At the same time, the pot body 4 can be raised to increase the distance between the top edge of the pot body 4 and the top edge of the pot cover 6, so as to better exhaust the hot air.

[0089] In this embodiment, the limiting structure 41 is a protrusion disposed on the edge of the opening of the pot body 4, the protrusion facing the upper pot cover 61 and located on the four sides of the pot body 4. In other embodiments, those skilled in the art can choose other suitable limiting structures 41.

[0090] Specifically, the lower pot cover 62 and the upper pot cover 61 are detachably connected, and the lower pot cover 62 and the base plate 2 are also detachably connected. The detachable connection uses screws. In other embodiments, other detachable connection methods may also be used.

[0091] Therefore, the detachable connection between the upper and lower pot covers 62 and between the lower pot cover 62 and the base plate 2 makes it easier to install and replace the pot cover 6, thus improving the installation efficiency of the cooking machine.

[0092] Specifically, such as Figure 2 As shown, the gas cooking appliance 100 also includes a control board 8, a power board 9, and a valve assembly 7. The control board 8 is disposed on the panel 1 and is electrically connected to the burner 3, the pot body 4, or the valve assembly 7. Preferably, the control board 8 is electrically connected to the burner 3, the pot body 4, and the valve assembly 7 simultaneously. The control board 8 is used to select cooking functions.

[0093] Among them, such as Figure 9 and Figure 10 As shown, the burner 3 includes a nozzle, a thermocouple 31, an ignition needle 32, a temperature measuring component 1010, an inner ring flame outlet cap 33, an outer ring flame outlet cap 34, a base, and a mixing chamber. The burner 3 is provided with an air inlet 35, which is connected to the pipe valve assembly 7. The nozzle is used to spray gas, the thermocouple 31 is used to shut off the gas supply in a timely manner, the ignition needle 32 generates an electric spark to ignite the gas, and the inner ring flame outlet cap 33 and the outer ring flame outlet cap 34 are used to heat the pot body 4.

[0094] like Figures 11-13 As shown, the pot body 4 includes a pot body 42 and a stirring assembly. The stirring assembly includes a lid 431, stirring blades 432, a drive device 433, and an operating handle 434. The pot body 42 extends through the placement opening 11 into the receiving cavity 5. The lid 431 covers the pot body 42, and the stirring blades 432 are located inside the pot body 42. Figure 12 As shown, the drive unit 433 includes a motor 4331, a gearbox 4332, and a rotating shaft 4333. The motor 4331 is connected to the gearbox 4332 and provides power to the gearbox 4332. The gearbox 4332 is connected to the rotating shaft 4333 and controls the rotation of the rotating shaft 4333. The rotating shaft 4333 passes through the cover 431 and is connected to the stirring blade 432. The operating handle 434 is electrically connected to the drive unit 433. The operating handle 434 includes a Bluetooth module, a battery, and a handle housing. The handle housing is connected to the drive unit 433. The battery and Bluetooth module are both located inside the handle housing. The Bluetooth module is electrically connected to the battery and the drive unit 433. The Bluetooth module is used to receive signals, specifically signals emitted by the control board 8. The Bluetooth module is used to control the switching on / off state and output power of the drive unit 433. The battery powers the drive unit 433.

[0095] like Figure 14 As shown, the valve assembly 7 includes a gas pipe 71 and a proportional valve 72. One end of the gas pipe 71 is connected to the proportional valve 72. The proportional valve 72 is provided with a gas outlet, which is connected to the gas inlet 35 of the burner 3. The other end of the gas pipe 71 passes through the chassis 2 and protrudes outside the chassis 2, and is connected to an external gas pipeline.

[0096] like Figure 2 As shown, the power board 9 is mounted on the chassis 2 and is used to receive the temperature signal emitted by the temperature measuring component 1010. Through calculation, it issues action commands to the stirrer assembly and the valve body assembly to realize intelligent cooking.

[0097] Specifically, the gas cooking appliance 100 also includes a temperature measuring component 10, which is disposed on the burner 3 and in contact with the bottom of the pot body 4. The temperature measuring component 10 is used to transmit the real-time temperature of the bottom of the pot body 4 to the power board 9.

[0098] Therefore, by setting up a temperature measuring device, the temperature at the bottom of the pot can be reflected more accurately, thereby improving the accuracy of the cooking machine's operation and enhancing its intelligence.

[0099] The working principle of the gas cooking machine 100 intelligent cooking is as follows: the temperature measuring component monitors the temperature of the bottom of the pot 4 in real time. According to different cooking needs, it feeds back the temperature of the bottom of the pot 4 to the power board 9 in real time. The power board 9 then transmits the temperature requirements to the pipe valve assembly 7, controls the output flow of the pipe valve assembly 7 to control the fire level. According to different cooking needs, the power board 9 controls the speed, direction and frequency of the stirring assembly through algorithms to achieve intelligent cooking.
