Description
TECHNICAL FIELD

[0002] At present, the circuit board of the integrated cooker integrates the controller of the smoke exhaust device, the steam oven, the cooktop and the like. The controller includes transistors, chips, inductors, capacitors, resistors and various electrical devices. In order to ensure the safe operation of the machine, the working temperature of all electrical devices should not exceed the standard working temperature.
[0003] With the increasing demand of users for the performance of the integrated cooker, such as the requirement of the air volume of the smoke exhaust device exceeding 25 m 3 / min, and the requirement of the maximum static pressure of the smoke exhaust device exceeding 1200 Pa, in order to meet the performance requirements of the users, the operating power of the entire circuit board will be very high, some electrical devices generate a large amount of heat, and in order to prevent water, moisture and rodents from damaging the circuit board, the circuit board is usually placed in a relatively closed environment, in which the air circulation is weak and the heat dissipation is difficult, resulting in that the working temperature of the electrical devices with a large amount of heat on the circuit board exceeds the standard, and hidden dangers are caused.
[0004] In the related art, the heat dissipation fins are increased on the electrical devices with a large amount of heat to increase the heat dissipation effect, or the fan is arranged on the circuit box to exhaust the heat in the circuit box by air flow. However, in the space with weak air circulation, the heat dissipation effect of the heat dissipation fins is limited, and the heat exhausted by the fan still remains in the frame of the integrated cooker and is not exhausted to the outside of the machine, resulting in poor heat dissipation effect. UTILITARIAN CONTENT
[0005] The present application provides a circuit box assembly and an integrated cooker, which can solve the technical problem of poor heat dissipation effect of the circuit box.
[0006] In a first aspect, the present application provides a circuit box assembly, which is arranged on a base of an integrated cooker, and includes:
[0007] a box body, which has an accommodating cavity formed therein;
[0008] a circuit board arranged in the accommodating cavity;
[0009] a first pipeline connected with the box body and communicating the accommodating cavity with the outside;
[0010] a second pipeline connected with the box body and communicating the accommodating cavity with a smoke exhaust air duct of the integrated cooker.
[0011] In some embodiments, the first pipeline and the second pipeline are respectively communicated with opposite sides of the box body.
[0012] In some embodiments, the circuit box assembly further comprises a protective mesh, which is arranged in the first duct.
[0013] In some embodiments, the box body is integrally formed with the first duct and the second duct.
[0014] In some embodiments, the box body has an air inlet hole and an air outlet hole, which are in communication with the accommodating cavity, the first duct is connected with the air inlet hole, and the second duct is connected with the air outlet hole.
[0015] In some embodiments, the circuit board has a heat generating component, and the air inlet hole is arranged opposite to the heat generating component.
[0016] In some embodiments, the circuit box assembly comprises a plurality of the first ducts and a plurality of the second ducts.
[0017] In some embodiments, the circuit box assembly comprises a fan, which is arranged in the first duct or the second duct.
[0018] In some embodiments, the first duct and the second duct are metal ducts, and the box body is a metal box body.
[0019] In some embodiments, one side of the box body has an opening in communication with the accommodating cavity, and the circuit box assembly further comprises a cover, which covers the opening and is used for opening and closing the opening.
[0020] In a second aspect, the embodiments of the present application provide an integrated kitchen, which is characterized in that comprising:
[0021] a base;
[0022] a cooktop arranged on the base;
[0023] an exhaust device arranged on the base, and the exhaust device has an exhaust air duct, and a smoke suction port of the exhaust air duct is arranged towards the cooktop;
[0024] a circuit box assembly as described above, which is arranged on the base, and a second duct of the circuit box assembly is in communication with the exhaust air duct.
[0025] In some embodiments, a first duct of the circuit box assembly extends towards a front of the base.
[0026] The circuit box assembly and the integrated kitchen according to the embodiments of the present application have at least the following beneficial effects:
[0027] By connecting the first pipe to the outside, outside air can flow into the housing cavity through the first pipe. By connecting the second pipe to the exhaust duct of the integrated stove, the exhaust duct can also be connected to the housing cavity. Thus, the first pipe, housing cavity, second pipe, and exhaust duct can be connected in sequence to form a flow channel. When the integrated stove starts to draw in smoke, the fan in the exhaust duct operates to generate suction force, creating negative pressure in the first pipe, housing cavity, second pipe, and exhaust duct. Low-temperature outside air (air with room temperature <40℃) can flow into the housing cavity through the first pipe. The low-temperature air flows over the circuit board and carries away the heat generated by the circuit board. Then, it enters the exhaust duct through the second pipe, and the air carrying the heat is discharged from the integrated stove. This allows the heat generated by the circuit board to be discharged to the outside through the integrated stove's own exhaust duct, preventing the heat generated by the circuit board from remaining in the frame of the integrated stove and improving the heat dissipation effect.

The term "and / or" used herein includes any and all combinations of one or more associated listed items.
[0040] In a first aspect, referring to Figure 1 An integrated cooker 100 provided by the embodiments of the present application includes a base 20, a cooker 30, a smoke exhaust device 40, and a circuit box assembly 10. The cooker 30 is arranged on the base 20, the smoke exhaust device 40 is also arranged on the base 20, and the smoke suction port 402 of the smoke exhaust device 40 can be arranged towards the cooker 30, so that the smoke exhaust device 40 can suck the smoke generated by the cooker 30 during cooking. The circuit box assembly 10 is also arranged on the base 20, and the second duct 4 of the circuit box assembly 10 can communicate with the smoke exhaust duct 401.
[0041] It can be understood that the top of the base 20 can have a mounting table, which can be horizontal, so that the cooktop 30 can be arranged on the mounting table, and the smoke exhaust device 40 is also arranged on the mounting table, and the cooktop 30 is located in the central area of the mounting table, and the smoke exhaust device 40 is arranged adjacent to the cooktop 30, so that the integrated stove 100 faces the user, and the back of the integrated stove 100 is away from the user, and the smoke exhaust device 40 is located on the side of the cooktop 30 close to the back, and the smoke suction port 402 of the smoke exhaust device 40 is located above the cooktop 30, so that the smoke generated by the cooktop 30 can be exhausted through the smoke suction port 402.

[0044] As shown in Figure 3 When the smoke exhaust device 40 starts to suck smoke, the arrow in Figure 3 indicates the flow direction of low-temperature air. More clearly, at this time, the fan of the smoke exhaust device 40 operates to generate suction force, so that the low-temperature air from the outside world flows into the circuit box assembly 10. After the low-temperature air absorbs heat in the circuit box assembly 10, it enters the smoke exhaust duct 401 through the second pipe 4. The air with heat is discharged from the integrated stove 100, so that the heat in the circuit box assembly 10 can be exhausted to the outside world through the smoke exhaust duct 401, preventing the heat generated by the circuit box assembly 10 from remaining in the integrated stove 100, and improving the heat dissipation effect.
[0045] In a second aspect, referring to Figure 4 , a circuit box assembly 10 provided by the embodiment of the present application is arranged on the base 20 of the integrated stove 100.

[0047] It can be understood that when the integrated stove 100 starts to suck smoke, the fan in the smoke exhaust duct 401 operates to generate suction force, so that negative pressure is formed in the first pipe 3, the receiving cavity 11, the second pipe 4, and the smoke exhaust duct 401, and the low-temperature air from the outside can flow into the receiving cavity 11 through the first pipe 3, the low-temperature air flowing through the circuit board 2 can take away the heat generated by the circuit board 2, and then the low-temperature air carrying the heat can enter the smoke exhaust duct 401 through the second pipe 4, and the air carrying the heat can be exhausted from the integrated stove 100, so that the heat generated by the circuit board 2 can be exhausted to the outside through the smoke exhaust duct 401 of the integrated stove 100, the heat generated by the circuit board 2 can be prevented from remaining in the whole machine frame of the integrated stove 100, and the heat dissipation effect can be improved.
[0048] Referring to Figure 4 In some embodiments, the first pipe 3 and the second pipe 4 are respectively in communication with opposite sides of the box body 1.
[0049] Optionally, the first pipe 3 can guide the low-temperature air from the outside to flow into the box body 1, the second pipe 4 can guide the air in the box body 1 to flow into the smoke exhaust duct 401, the first pipe 3 and the second pipe 4 are respectively in communication with opposite sides of the box body 1, so that the air flow can flow from one side of the box body 1 to the other side of the box body 1, the air flow in the box body 1 is consistent, the air flow can smoothly flow through the box body 1, the air flow passing through the box body 1 can be increased, so that more heat can be taken away, and the heat dissipation effect can be further improved.
[0050] Referring to Figure 2 and Figure 4 In some embodiments, the first pipe 3 of the circuit box assembly 10 extends towards the front of the base 20.
[0051] It can be understood that the front of the base 20 is the side of the base 20 facing the user, the back of the base 20 is the side of the base 20 facing away from the user, and the base 20 is usually embedded in the cabinet against the wall, that is, the back of the base 20 is arranged towards the wall, and the left and right sides of the base 20 are respectively provided with a cabinet, so that the base 20 only has space in the front, and the first duct 3 is arranged to extend towards the front of the base 20, so that the first duct 3 is convenient for being communicated with the outside, and the low-temperature air outside is convenient for being sucked into the containing cavity 11 to dissipate heat for the circuit board 2.
[0052] Please refer to Figure 2 and Figure 4 In some embodiments, the circuit box assembly 10 further comprises a protective screen 5 arranged in the first duct 3.
[0053] It should be noted that when the integrated cooker 100 starts to suck flue gas, negative pressure will be generated in the first duct 3, at this time, the first duct 3 is equivalent to a small air suction pipe, and the first duct 3 will suck air and sundries in the air into the containing cavity 11, which is easy to pollute the circuit board 2 in the containing cavity 11, and especially after water is sucked into the containing cavity 11, the risk of short circuit of the circuit board 2 is easily caused.
[0054] The protective screen 5 is arranged in the first duct 3, which can prevent sundries from being sucked into the containing cavity 11 when the integrated cooker 100 starts to suck flue gas, and the protective screen 5 can also prevent insects, rats and the like from entering the containing cavity 11 to bite the circuit board 2. For example, the protective screen 5 is arranged at the pipe opening of the first duct 3 communicated with the outside, so that the protective screen 5 can isolate the sundries outside the first duct 3.
[0055] Preferably, the protective screen 5 can be a waterproof screen, which can prevent water vapor from entering the containing cavity 11 and prevent the risk of short circuit of the circuit board 2.
[0056] In some embodiments, the box body 1 is integrally formed with the first duct 3 and the second duct 4, so that the box body 1, the first duct 3 and the second duct 4 can become an integral whole, which can enhance the strength and stability of the whole structure, and without the need for separate assembly steps, thereby reducing the manufacturing cost and time, and the integral forming can also reduce or eliminate the joint between the box body 1 and the first duct 3 and the second duct 4, thereby improving the sealing performance of the containing cavity 11.

The first pipeline 3, the second pipeline 4 and the box body 1 are separately provided, when one of the first pipeline 3, the second pipeline 4 and the box body 1 fails or needs to be maintained, the part can be individually disassembled without affecting the normal operation of other parts, facilitating subsequent maintenance.
[0059] Please refer to Figure 4 In some embodiments, the circuit board 2 has a heat generating component 21, and the air inlet hole 12 is arranged opposite the heat generating component 21.
[0060] It can be understood that the heat generated by the circuit board 2 during operation is mainly concentrated on the heat generating component 21, and the air inlet hole 12 is arranged opposite the heat generating component 21, so that the low-temperature air flowing into the containing cavity 11 can first contact the heat generating component 21, facilitating the low-temperature air to directly exchange heat with the heat generating component 21 and carry away heat, and further improving the heat dissipation effect.
[0061] In some embodiments, the circuit box assembly 10 includes a plurality of first pipelines 3 and a plurality of second pipelines 4.

The fan 6 can also be arranged in the second pipe 4, and when the fan 6 rotates, the high-temperature air in the containing cavity 11 can be sucked into the smoke exhaust duct 401 and discharged to the outside, so that the temperature in the containing cavity 11 is reduced, and the heat dissipation effect is improved.
[0065] In addition, even when the fan of the smoke exhaust device 40 does not work, the fan 6 can be started to suck low-temperature air into the containing cavity 11 to cool the circuit board 2.
[0066] In some embodiments, the first pipe 3 and the second pipe 4 are metal pipes, and the box body 1 is a metal box body 1.
