DETAILED DESCRIPTION

[0043] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper restriction on this application.

[0044] The present application embodiment provides a stove installation structure, see Figures 1 to 10 The invention comprises a mounting assembly 10, a stove plate 20, a base cup device 30, and a burner head 40. The mounting assembly 10 comprises a mounting bracket 11, a stove plate 20 is mounted on the mounting assembly 10, and a through hole is provided on the stove plate 20; the base cup device 30 is connected to the mounting bracket 11, and the base cup device 30 has a gas passage 30a, which is connected to the through hole; and the burner head 40 is mounted on the stove plate 20 and is connected to the gas passage 30a.

[0045] Another aspect of the present invention provides a cooking appliance. Figures 1 to 10 , including the stove installation structure of any one of the above embodiments.

[0046] The cooking device of the embodiment of the present application is a large oven, wherein the mounting assembly 10 includes a large oven body, and the stove plate 20 is arranged on the large oven body.

[0047] In some embodiments, the cooking device can also be an oven, a steam oven, etc., and a stove can be integrated into cooking devices with different functions according to user needs to improve the convenience of kitchen use.

[0048] In the related art, the bottom cup device is located below the stove plate, and there is no supporting fixed structure below the bottom cup device. When the bottom cup device and the stove plate are assembled, there is a problem of improper assembly. Manual assembly can easily cause the bottom cup device to tilt, and the eccentricity of the gas jet can easily lead to uneven flame distribution, yellow flames, and other phenomena. At the same time, it leads to the problem of difficult assembly operation and low assembly efficiency of the bottom cup device.

[0049] The stove installation structure of the embodiment of the present application is shown in FIG. Figure 1 and Figure 2 The mounting assembly 10 includes a mounting bracket 11, and the bottom cup device 30 is connected to the mounting bracket 11. Therefore, when the stove plate 20 is set on the mounting assembly 10, the gas channel 30a of the bottom cup device 30 is connected to the through hole. That is to say, by providing the mounting bracket 11, the bottom cup device 30 is connected to the mounting bracket 11 to position the bottom cup device 30, thereby solving the problem of the bottom cup device 30 not being properly assembled. At the same time, the difficulty of the assembly operation of the bottom cup device 30 is reduced and the assembly efficiency of the bottom cup device 30 is improved.

[0050] Among them, the specific number of the bottom cup device 30 and the through holes is not limited here. The number of the bottom cup device 30 can be one or more. It can be understood that the number of the through holes can be one or more. The bottom cup device 30 corresponds to the through holes one by one, and the multiple through holes are evenly distributed on the stove plate 20, so that the heat can be evenly distributed on the stove.

[0051] In one embodiment, please refer to Figure 2 and Figure 6 A first positioning hole 11 a is formed on the mounting bracket 11 , and a portion of the structure of the bottom cup device 30 is disposed in the first positioning hole 11 a .

[0052] By forming a first positioning hole 11a on the mounting bracket 11, part of the structure of the bottom cup device 30 is passed through the first positioning hole 11a to position the bottom cup device 30, thereby preventing the bottom cup device 30 from tilting, and preventing the occurrence of uneven flame distribution and yellow flame after the gas jet is eccentric. This can solve the problem of the bottom cup device 30 not being properly assembled. At the same time, the mounting bracket 11 can support the bottom cup device 30, and can achieve the purpose and effect of pre-positioning the bottom cup device 30, keeping the bottom cup device 30 from tilting, and reducing the stress and deformation between the bottom cup device 30 and the stove plate 20.

[0053] In one embodiment, the bottom cup device 30 is tightly connected to the mounting bracket 11 , which further improves the connection reliability between the bottom cup device 30 and the mounting bracket 11 .

[0054] Specifically, fastening holes are provided around the first positioning hole 11 a. The bottom cup device 30 is first inserted into the first positioning hole 11 a. At this time, the fastening holes of the bottom cup device 30 are aligned with the fastening holes of the mounting bracket 11. Fasteners are used to fasten the bottom cup device 30 to the mounting bracket 11.

[0055] The number of bottom cup devices 30 provided on the mounting bracket 11 is not limited. For example, see Figure 6 Two bottom cup devices 30 are provided on each mounting bracket 11, and two first positioning holes 11a are formed on the mounting bracket 11. The two bottom cup devices 30 cooperate with the mounting bracket 11 through the first positioning holes 11a respectively, which can reduce the number of mounting brackets 11, save resources, and improve assembly efficiency.

[0056] In some embodiments, the bottom cup device 30 and the mounting bracket 11 may be connected and fixed by gluing, snapping, or other connection methods.

[0057] In one embodiment, please refer to Figure 1 The mounting assembly 10 includes a box body 12 , a stove plate 20 is disposed on the box body 12 , and a mounting bracket 11 is connected to the box body 12 .

[0058] During installation, the bottom cup device 30 is first installed on the mounting bracket 11, and then the mounting bracket 11 is connected to the box body 12 to ensure that the mounting bracket 11 is stably connected to the box body 12, and then the bottom cup device 30 is positioned so that the gas channel 30a of the bottom cup device 30 is connected to the through hole of the stove plate 20, thereby preventing safety problems caused by the bottom cup device 30 being tilted.

[0059] Specifically, see Figure 6 The opposite ends of the mounting bracket 11 are folded to form mounting platforms 11b, and each mounting platform 11b is fastened to the box body 12 respectively. While facilitating the connection, the opposite ends of the mounting bracket 11 are folded to form mounting platforms 11b, so that an accommodating space is formed between the mounting bracket 11 and the stove plate 20 for accommodating the bottom cup device 30.

[0060] Furthermore, a mounting groove is formed on the box body 12 so that the mounting platform 11b is embedded in the mounting groove. When the mounting platform 11b is fastened to the box body 12, the mounting bracket 11 is positioned while further improving the stability of the connection structure between the mounting platform 11b and the box body 12.

[0061] In some embodiments, the box body 12 and the mounting bracket 11 may be connected and fixed by gluing, snapping, or other connection methods.

[0062] In some embodiments, the mounting bracket 11 is connected to the cooktop plate 20 .

[0063] In one embodiment, please refer to Figure 1 and Figure 2 The bottom cup device 30 includes a bottom cup 31 (gas jet device) having a gas channel 30 a , and the bottom cup 31 is fastened to the mounting bracket 11 .

[0064] The upper end of the bottom cup 31 is connected to the through hole, and the lower end is connected to the gas pipeline, so that the gas in the gas pipeline flows to the burner 40 through the gas channel 30a of the bottom cup 31. During installation, the bottom cup 31 is first tightly connected to the mounting bracket 11, and then the mounting bracket 11 is connected to the box body 12 to achieve a stable connection between the mounting bracket 11 and the box body 12, thereby positioning the bottom cup 31.

[0065] In some embodiments, the bottom cup 31 and the mounting bracket 11 may be connected and fixed by gluing, snapping, or other connection methods.

[0066] In one embodiment, please refer to Figure 4 The bottom cup 31 includes an air inlet end 311, a mounting end 312, and a connecting portion 313 connecting the air inlet end 311 and the mounting end 312. The air inlet end 311 of the bottom cup 31 is disposed in the first positioning hole 11a to position the bottom cup 31.

[0067] See also Figure 4 The outer wall of the air inlet end 311 extends radially outward to form a first mounting plate 311a, and the first mounting plate 311a is fastened to the mounting bracket 11. When the bottom cup 31 is set on the mounting bracket 11, the air inlet end 311 of the bottom cup 31 is inserted into the first positioning hole 11a, and the first mounting plate 311a abuts against the upper surface of the mounting bracket 11, thereby increasing the contact area between the bottom cup 31 and the mounting bracket 11, thereby preventing the bottom cup 31 from tilting relative to the through hole, improving the assembly accuracy, and being fastened to the mounting bracket 11 by the first mounting plate 311a, further improving the connection stability between the bottom cup 31 and the mounting bracket 11.

[0068] See also Figure 4 An air intake channel 311b having an inlet and an outlet is formed inside the air intake end 311. The air intake channel 311b constitutes at least part of the gas channel 30a, and the outlet faces the through hole. When the air intake end 311 is inserted into the first positioning hole 11a, the inlet of the air intake end 311 is located below the mounting bracket 11 and is connected to the gas pipeline.

[0069] In one embodiment, please refer to Figure 4The mounting end 312 includes a second mounting plate 312a, which is securely connected to the stove plate 20. When the bottom cup 31 is mounted on the mounting bracket 11, which is connected to the housing 12, the second mounting plate 312a abuts against the lower surface of the stove plate 20, thereby increasing the contact area between the bottom cup 31 and the stove plate 20. This prevents the bottom cup 31 from tilting relative to the through-hole, improving assembly accuracy, and the secure connection between the second mounting plate 312a and the stove plate 20 further improves the connection stability between the bottom cup 31 and the stove plate 20 and reduces stress and deformation between the bottom cup 31 and the stove plate 20.

[0070] Understandably, see Figure 4 The first mounting plate 311a and the second mounting plate 312a are respectively fastened to the mounting bracket 11 and the stove plate 20, for example, by screws passed through the fastening holes for fixation, that is, the first mounting plate 311a and the second mounting plate 312a are both provided with fastening holes. During the assembly process, the first mounting plate 311a and the second mounting plate 312a are generally installed respectively by operating the air screwdriver. Therefore, in order to have enough operating space for the air screwdriver, the first mounting plate 311a and the second mounting plate 312a are set at a certain angle to realize the air-avoiding operation of actually installing screws with the air screwdriver in the vertical space. The angle range can be 25°-150°. For example, the angle is 45°.

[0071] See also Figure 4 The second mounting plate 312a has an escape channel 312b formed thereon. One end of the escape channel 312b is connected to the through hole, and the other end is connected to the outlet. Part of the burner head 40 can extend into the escape channel 312b, allowing gas to enter the burner head 40 through the gas channel 30a.

[0072] In some embodiments, the bottom cup 31 is connected to the mounting bracket 11 via the first mounting plate 311 a and is fixed to the housing 12 via the mounting bracket 11 to position the bottom cup 31 . The mounting end 312 of the bottom cup 31 is not connected to the stove plate 20 .

[0073] In one embodiment, please refer to Figure 4 At least part of the side wall of the avoidance channel 312b extends in a direction away from the air inlet end 311 to form a limiting rib 312c, and the limiting rib 312c is plugged into and matched with the through hole. The plug-in cooperation between the limiting rib 312c and the through hole further improves the connection stability between the bottom cup 31 and the stove plate 20.

[0074] Among them, the "at least part of the side wall of the avoidance channel 312b extends in a direction away from the air inlet end 311 to form a limiting rib 312c" means that the side wall of the avoidance channel 312b extends in a direction away from the air inlet end 311 to form an annular limiting rib 312c, and it may also mean that part of the side wall of the avoidance channel 312b extends in a direction away from the air inlet end 311 to form a partially annular limiting rib 312c. There may be multiple limiting ribs 312c or one.

[0075] In one embodiment, please refer to Figure 3 The bottom cup device 30 includes a nozzle 32, which is arranged at the outlet so that the gas entering the air inlet channel 311b is sprayed toward the through hole through the nozzle 32.

[0076] Among them, the connection method between the nozzle 32 and the air inlet end 311 is not limited here. For example, an axial air hole is provided in the nozzle 32, the outlet end of the air inlet end 311 forms an internal thread, and the outer periphery of the bottom end of the nozzle 32 is formed with an external thread. During assembly, the nozzle 32 and the air inlet end 311 are fixed by threaded cooperation. The threaded installation has a stable and reliable self-locking function, which makes the installation reliable and not easy to slip out of place.

[0077] In one embodiment, please refer to Figure 4 Part of the side wall of the avoidance channel 312 b extends toward the air inlet end 311 and abuts against the first mounting plate 311 a , and the connecting rib is the connecting portion 313 of the bottom cup 31 .

[0078] Among them, the "partial side wall of the avoidance channel 312b extends in a direction away from the air inlet end 311 to form a limiting rib 312c" means that the connecting rib is a non-circumferential closed structure, and a circumferential opening 35c for air supply is provided in the peripheral structure of the nozzle 32, thereby ensuring the air supply and improving the combustion performance.

[0079] In one embodiment, please refer to Figure 3 The bottom cup assembly 30 includes a connecting pipe 33, which is sealedly connected to the gas inlet end 311 and communicates with the inlet. The lower end of the bottom cup 31 is connected to the connecting pipe 33, and is connected to the gas pipeline through the connecting pipe 33, so that the gas in the gas pipeline flows to the burner 40 through the gas channel 30a of the bottom cup 31.

[0080] Specifically, see Figure 3 A stepped surface is formed in the air inlet passage 311b, and the stovetop mounting structure includes a sealing ring 34 that abuts the stepped surface. One end of the connecting tube 33 extends into the inlet and abuts the sealing ring 34, while the other end is exposed at the air inlet end 311. The provision of the sealing ring 34 in the air inlet end 311 improves the sealing between the connecting tube 33 and the bottom cup 31.

[0081] The specific type of the connecting pipe 33 is not limited here. For example, the connecting pipe 33 is an aluminum gas pipe.

[0082] In addition, the specific type of the sealing ring 34 is not limited here. Exemplarily, the sealing ring 34 is a rubber ring.

[0083] In one embodiment, please refer to Figure 3 and Figure 5 The bottom cup device 30 includes a connecting bracket 35, one end of which is connected to the air inlet end 311, and the other end is connected to the connecting pipe 33. It can be understood that by providing the connecting bracket 35, the bottom cup 31 and the connecting pipe 33 are sealed and can be easily disassembled, assembled, repaired, and replaced.

[0084] The connection method of the connecting bracket 35, the bottom cup 31 and the connecting pipe 33 is not limited here. For example, please refer to Figure 3 and Figure 5 The outer peripheral surface of the air inlet end 311 of the bottom cup 31 forms a bulge 311c, and the outer peripheral surface of the connecting tube 33 forms a flange 33a; one end of the connecting bracket 35 is provided with a snap ring 35b that is snap-fitted with the flange 33a, and the other end of the connecting bracket 35 is provided with a snap-fitting hole 35a that is snap-fitted with the bulge 311c.

[0085] During installation, one end of the connecting tube 33 is inserted into the clamping ring 35b, the flange 33a of the connecting tube 33 is engaged with the clamping ring 35b, and the convex bump 311c formed on the outer peripheral surface of the air inlet end 311 is engaged with the clamping hole 35a of the connecting bracket 35 to generate a locking force on the connecting tube 33, thereby sealing the bottom cup 31 and the connecting tube 33.

[0086] In the related art, the airtightness between the connecting pipe and the bottom cup is mainly achieved by the cooperation between the flange formed on the outer peripheral surface of the connecting pipe and the step surface of the bottom cup, and the connecting pipe deforms under the thrust generated by the rotation of the nut thread to achieve full contact and airtightness. However, there are two problems with the above method: 1) During later maintenance, the pier head becomes larger in size after deformation, making it difficult to pull out, and the parts cannot be reused; 2) Manual assembly operations are inefficient and costly.

[0087] In the embodiment of the application, the threaded structure and the process of tightening the nut are eliminated between the bottom cup 31 and the connecting tube 33. Instead, a rubber ring is used for sealing. The bottom cup 31 and the connecting tube 33 are connected by a connecting bracket 35. Sufficient stress is applied to prevent the rubber ring surface and the step surface of the bottom cup 31 from falling off and causing gap leakage, thereby achieving good air tightness, improving production efficiency and reducing costs.

[0088] Among them, the specific type of the connecting bracket 35 is not limited here. For example, the connecting bracket 35 is a spring steel structure, so that the connecting bracket 35 has sufficient strength, toughness and elasticity, allowing it to be assembled with the connecting pipe 33 and closely contact the clamping ring 35b to achieve a non-falling effect, and the clamping hole 35a is embedded in the convex bump 311c; through the above structural fixation, the sealing ring 34 can be closely fitted with the step surface while maintaining a compressed state to achieve an airtight and safe effect.

[0089] In some embodiments, a flange 33a is formed on the outer peripheral surface of the air inlet end 311 of the bottom cup 31, a bulge 311c is formed on the outer peripheral surface of the connecting tube 33, a snap ring 35b that snaps into engagement with the flange 33a is provided at one end of the connecting bracket 35, and a snap-in hole 35a that snaps into engagement with the bulge 311c is provided at the other end of the connecting bracket 35.

[0090] In one embodiment, please refer to Figure 5 One side of the clamping ring 35b has an opening 35c, and the connecting pipe 33 is inserted into the clamping ring 35b through the opening 35c, which is convenient for assembly and disassembly.

[0091] The central angle corresponding to the opening 35c of the snap ring 35b may range from 10° to 60°. For example, the central angle corresponding to the opening 35c is 30°.

[0092] In one embodiment, please refer to Figure 1 and Figure 2 The burner head 40 includes an ignition needle 43, which is arranged on the bottom cup 31 and is used to ignite the gas.

[0093] In one embodiment, please refer to Figure 1 and Figure 2 The burner head 40 includes a thermocouple 44, which is provided on the bottom cup 31. The thermocouple 44 is used to detect the temperature at the burner head 40 and feed the detected temperature back to the controller. The controller controls the supply of gas according to the temperature at the burner head 40, thereby improving the reliability of the product. Specifically, when the stove is in working condition, the gas at the burner head 40 is ignited, and the thermocouple 44 detects that the burner head 40 has a high temperature. The controller determines that the stove is in normal working condition. When the flame at the burner head 40 is blown out, the thermocouple 44 detects that the temperature at the burner head 40 is low. The controller determines that the stove is in abnormal working condition and controls the gas supply to stop, thereby avoiding the risk of gas leakage and further improving the reliability of the product.

[0094] In the related art, the safe use of the burner head 40 requires the matching use of the ignition pin 43 and the thermocouple 44. The ignition pin 43 and the thermocouple 44 are usually installed on the bottom cup 31. However, due to the inconsistent structural dimensions of the burner head 40, the positions of the ignition pin 43 and the thermocouple 44 are inconsistent. In the related art, one burner head 40 corresponds to one bottom cup 31, which provides higher requirements and challenges for the universal design of the bottom cup 31.

[0095] The stove installation structure in the embodiment of this application is shown in FIG. Figures 7 to 10 The burner head 40 can be either a seal burner 41 or an open burner 42. Since the ignition needle 43 and the thermocouple 44 of different burners 40 are set in different positions, the bottom cup 31 in the embodiment of the present application can be applied to both the seal burner 41 and the open burner 42, thereby achieving the universal installation requirements of the bottom cup 31 and the seal burner 41 and the open burner 42.

[0096] Among them, see Figure 7 The open burner 42 includes a fire cover 421 and a first flamethrower 422. Figure 9 The rotary burner head 41 includes a second flamethrower 411 .
