For safe operation, the operating temperature of all electrical components must not exceed their standard operating temperature. However, the circuit board is located inside the integrated cooktop, where air circulation is weak and heat dissipation is difficult. This can cause the operating temperature of components on the circuit board that generate significant heat to exceed their limits, creating a potential hazard.

[0003] Currently, outside air can be introduced into the control box to dissipate heat from the relevant components. However, this solution requires openings in the control box to allow airflow in and out.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

[0038] Please see Figure 1 This invention provides an electronic control component 200, which includes an electronic control box 201, an electronic control module 202, and a fan 203. The electronic control box 201 has a housing space 204, which is a sealed space. The electronic control module 202 is disposed within the housing space 204. The fan 203 is disposed within the housing space 204 and is configured to generate internal circulating airflow within the housing space 204 during operation.

[0039] In the aforementioned electronic control component 200, the accommodating space 204 within the electronic control box 201 is a sealed space, thereby preventing moisture and insects from entering the electronic control box 201 due to openings in the box. When the fan 203 operates, it can create an internal circulating airflow within the accommodating space 204, which helps to even out the temperature within the electronic control box 201, thus ensuring that the electronic control module 202 operates within its normal temperature range.

[0040] Specifically, in combination Figure 7 Household appliance 100 includes an electronic control component 200. Household appliance 100 includes, but is not limited to, cooking equipment, cleaning equipment, heating equipment, range hoods, water purifiers, dishwashers, and disinfection cabinets. Cooking equipment includes, but is not limited to, integrated cooktops, microwave ovens, and microwave-steam-grill combos. An integrated cooktop is a kitchen appliance used for cooking food, heating and keeping warm, disinfecting, and exhausting fumes. The electronic control component 200 is the core component for controlling and regulating the functions of household appliance 100. Figure 7 Among the household appliances, 100 are integrated stoves.

[0041] In related technologies, integrated cooktops include an electrical control box, which houses a circuit board and control devices on the board (including but not limited to IGBT transistors, MCU chips, inductors, capacitors, resistors, and other electrical components). For safe operation, the operating temperature of all electrical components must not exceed their standard operating temperature. However, the circuit board is located inside the integrated cooktop, where air circulation is weak and heat dissipation is difficult. This can cause the operating temperature of components on the circuit board that generate significant heat to exceed their limits, creating a potential hazard.

[0042] Outside air can be introduced into the control box to dissipate heat from the components. However, this solution requires openings in the control box to allow airflow in and out. These openings can easily allow moisture, rodents, and insects to enter the control box, damaging the circuit boards and electrical components.

[0043] In this embodiment of the invention, the electronic control assembly 200 may include an electronic control box 201, an electronic control module 202, and a fan 203. The electronic control box 201 is a housing structure that accommodates the electronic control module 202, and its interior forms an accommodating space 204, within which the electronic control module 202 can be housed. The electronic control module 202 is the core circuit responsible for controlling the operation of the household appliance 100. The fan 203 is used for heat dissipation, helping the electronic control module 202 maintain a normal temperature during the operation of the household appliance 100. Optionally, the electronic control module 202 includes a circuit board 224 and electronic components disposed on the circuit board 224, including but not limited to capacitors, resistors, inductors, chips, transformers, IGBTs, etc.

[0044] The fan 203 is located within the enclosure 204. During operation, it can create an internal circulating airflow within the enclosure 204 to dissipate heat from the electronic control module 202. It is understood that the enclosure 204 is a sealed space, and there is virtually no convection between the air inside and outside the electronic control box 201.

[0045] During the process of fan 203 working to form internal circulating airflow to cool the electronic control module 202, fan 203 can draw in air from a part of the accommodating space 204 and blow air out toward another part of the accommodating space 204, thereby forming internal circulating airflow within the accommodating space 204.

[0046] Specifically, when fan 203 starts operating, a portion of the air in the accommodating space 204 is drawn into fan 203. As the drawn-in air passes through the blades of fan 203, the high-speed rotation of the blades exerts a pushing force on the air, increasing its velocity and directionality. The air is then blown out of fan 203 and flows to another part of the accommodating space 204. Simultaneously, under the influence of air pressure, air continuously flows from another part of the accommodating space 204 to another part of the accommodating space 204, and is drawn back into fan 203, thus forming a stable internal circulating airflow.

[0047] As the airflow circulates within the containment space 204, when it comes into contact with higher-temperature electronic components, the heat from the electronic components is transferred to the air through heat exchange. Conversely, when it comes into contact with lower-temperature electronic components, the heat from the air is transferred to the electronic components through heat exchange. This process repeats, which helps to even out the temperature within the control box 201. Simultaneously, the heat within the control box 201 can be conducted to the outside of the control box 201, which is beneficial for ensuring that the control module 202 operates within its normal temperature range.

[0048] It is understandable that in related technologies, opening holes in the control box to introduce and expel airflow may affect the performance of electrical components outside the control box of the household appliance. However, in this embodiment of the invention, by using the fan 203 to form an internal circulating airflow within the accommodating space 204 to dissipate heat from the control module 202, the impact on the performance of electrical components outside the control box 201 of the household appliance 100 can be reduced. At the same time, the airflow circulating within the control box 201 can make the temperature inside the control box 201 more uniform and, to a certain extent, ensure that all electronic components operate within the normal temperature range.

[0049] In some embodiments, at least a portion of the electrical control box 201 has a thermal conductivity greater than 90 W / (m·K).

[0050] In the above embodiments, at least a portion of the electrical control box 201 has a thermal conductivity greater than 90 W / (m·K), which can conduct heat inside the electrical control box 201 to the outside of the electrical control box 201 more quickly, which is beneficial for the electrical control module 202 to operate within the normal temperature range.

[0051] Specifically, the higher the thermal conductivity, the stronger the thermal conductivity of the control box 201, and the faster the heat inside the control box 201 is conducted to the outside of the control box 201.

[0052] In one implementation, such as Figure 4 As shown, the electrical control box 201 includes a box body 210 and a box cover 211, and at least one of the box body 210 and the box cover 211 is made of a material with a thermal conductivity greater than 90 W / (m·K). In one embodiment, as... Figure 3 As shown, the electrical control box 201 includes a box body 210, a box cover 211, and a top cover 212. At least one of the box body 210, the box cover 211, and the top cover 212 is made of a material with a thermal conductivity greater than 90 W / (m·K).

[0053] The thermal conductivity is greater than 90 W / (m·K). In some cases, the thermal conductivity is equal to 91 W / (m·K), 93 W / (m·K), 95 W / (m·K), 98 W / (m·K), 100 W / (m·K), 105 W / (m·K), or other values ​​greater than 90 W / (m·K).

[0054] It is understood that at least a portion of the material of the electrical control box 201 may include, but is not limited to, metal, silicon carbide, thermally conductive plastic composite material, metal matrix composite material, etc.

[0055] In some embodiments, at least a portion of the control box 201 is made of metal.

[0056] In the above embodiments, metal has good thermal conductivity. At least a part of the material of the control box 201 is metal, which can conduct heat inside the control box 201 to the outside of the control box 201 more quickly. This is beneficial for the control module 202 to work within the normal temperature range, and can also improve the structural strength of the control box 201.

[0057] Specifically, metals are materials with high thermal conductivity, and the free electrons within them play a crucial role in heat conduction. In the atomic structure of metals, free electrons can move freely between the atomic nuclei. When affected by temperature differences, these free electrons can rapidly move from high-temperature regions to low-temperature regions, transferring heat energy throughout the material. Therefore, the thermal conductivity of metallic materials is often much higher than that of other materials.

[0058] In one implementation, such as Figure 4 As shown, the electrical control box 201 includes a box body 210 and a box cover 211, and at least one of the box body 210 and the box cover 211 is made of metal. In one embodiment, as... Figure 3 As shown, the electrical control box 201 includes a box body 210, a box cover 211, and a top cover 212, and at least one of the box body 210, the box cover 211, and the top cover 212 is made of metal.

[0059] It is understandable that metals can include, but are not limited to, alloys, aluminum, copper, and silver.

[0060] In some implementations, please refer to Figure 2 The electrical control box 201 is provided with a partition 205, which divides the accommodating space 204 into a first space 206 and a second space 207. The electrical control module 202 is located in the first space 206, and the fan 203 is located in the second space 207. The partition 205 is provided with a first opening 208 and a second opening 209, both of which are connected to the first space 206 and the second space 207.

[0061] In the above embodiments, the electrical control box 201 is provided with a partition 205, which can divide the accommodating space 204 into a first space 206 and a second space 207, thereby realizing the circulation of airflow in the electrical control box 201, making the temperature in the electrical control box 201 tend to be uniform, which is beneficial to make the electrical control module 202 work within the normal temperature range.

[0062] Specifically, the partition 205 divides the accommodating space 204 into a first space 206 and a second space 207. The electronic control module 202 is located in the first space 206, and the fan 203 is located in the second space 207. The partition 205 has a first opening 208 and a second opening 209, both of which communicate with the first space 206 and the second space 207.

[0063] When the fan 203 operates within the second space 207, it can create a more stable directional airflow path. The first opening 208 and the second opening 209 on the partition 205 connect the two spaces respectively, allowing air to enter from the second space 207 through the first opening 208, flow through the first space 206 where the electronic control module 202 is located, and then flow from the first space 206 through the second opening 209 to the second space 207 where the fan 203 is located, thereby forming an internal circulating airflow.

[0064] It is understood that the first opening 208 and the second opening 209 can be one or more of the following: grid-shaped, mesh-like, elongated, circular, rectangular, and honeycomb-shaped openings. Preferably, the first opening 208 and the second opening 209 are circular or rectangular openings.

[0065] In some implementations, please refer to Figures 2 to 3 The electrical control box 201 includes a box body 210, a box cover 211 and a top cover 212. The box body 210 and the top cover 212 are respectively connected to opposite sides of the box cover 211. The box body 210 has a first space 206, the top cover 212 has a second space 207, and a part of the box cover 211 serves as a partition 205.

[0066] In the above embodiments, a first space 206 for accommodating the electronic control module 202 and a second space 207 for accommodating the fan 203 can be formed between the box body 210, the box cover 211 and the top cover 212. The first space 206 and the second space 207 are connected through the first opening 208 and the second opening 209, thereby enabling the circulating airflow to circulate within the electronic control box 201, making the temperature inside the electronic control box 201 tend to be more uniform, which is beneficial for the electronic control module 202 to operate within the normal temperature range.

[0067] Specifically, the box body 210 and the box cover 211 form a first space 206, which can accommodate the electronic control module 202. The box cover 211 and the top cover 212 form a second space 207, which can accommodate the fan 203. The box cover 211 may be provided with a first opening 208 and a second opening 209, both of which communicate with the first space 206 and the second space 207.

[0068] When the fan 203 operates within the second space 207, it can create a more directional airflow path. The first opening 208 and the second opening 209 on the cover 211 connect the two spaces respectively, allowing air to enter from the second space 207 through the first opening 208, flow through the first space 206 where the electronic control module 202 is located, and then flow from the first space 206 through the second opening 209 to the second space 207 where the fan 203 is located, thereby forming an internal circulating airflow.

[0069] exist Figure 2 In the embodiment shown, fan 203 is centrifugal fan 217. The air inlet of centrifugal fan 217 faces the second opening 209, and the air outlet faces the first opening 208.

[0070] In some implementations, please refer to Figure 2 The cover 211 has a snap hole 213 and a fixing hole 214, and the top cover 212 has a snap part 215 and a fixing part 216. The snap part 215 is inserted into the snap hole 213 and fastened to the cover 211. The electronic control assembly 200 includes a fastener. The fastener passes through the fixing part 216 and the fixing hole 214 and fixes the fixing part 216 to the cover 211.

[0071] In the above embodiments, the top cover 212 and the box cover 211 can be detachably connected together by the cooperation of the buckle part 215 and the buckle hole 213, as well as the fastener, the fixing part 216 and the fixing hole 214. This simplifies the installation process and further ensures the firm connection between the top cover 212 and the box cover 211. This is beneficial for the maintenance and repair of the electrical control box 201 and, to a certain extent, avoids the connection from loosening due to vibration or external force.

[0072] Specifically, the snap fastener 215 can be inserted into the snap hole 213, and then the top cover can be moved away from the fixing hole 214 so that the snap fastener 215 is snapped into the edge of the box cover 211 surrounding the snap hole 213, thereby initially positioning the top cover 212 and the box cover 211. At this time, the through hole 225 on the fixing part 216 is aligned with the fixing hole 214, and then the fastener passes through the through hole 225 of the fastener part and the fixing hole 214 to complete the firm connection between the box cover 211 and the top cover 212.

[0073] When the electrical control box 201 needs maintenance or repair, the fasteners can be removed, and then the top cover 212 can be moved toward the fixing hole 214 to separate the latching part 215 from the edge of the box cover 211 that forms the locking hole 213. Then the latching part 215 and the locking hole 213 can be separated to complete the disassembly between the box cover 211 and the top cover 212.

[0074] In some implementations, please refer to Figure 2 and Figure 5 The fan 203 includes a centrifugal fan 217, which is located at one end of the second space 207 along the length of the electrical control box 201.

[0075] In the above embodiment, the centrifugal fan 217 is located at one end of the second space 207 along the length of the electrical control box 201, which can form an internal circulating airflow in the electrical control box 201. To a certain extent, this ensures that the internal circulating airflow can flow through all electronic components, making the temperature in the electrical control box 201 more uniform, which is beneficial for the electrical control module 202 to work within the normal temperature range.

[0076] Specifically, centrifugal fan 217 is a fan 203 that draws air in from the center of fan 203 and discharges it radially (perpendicular to the axial direction) by means of a rotating impeller.

[0077] In the embodiments of the present invention, please refer to Figure 2 and Figure 5 A centrifugal fan 217 is located at one end of the second space 207 along the length of the electrical control box 201. The air inlet of the centrifugal fan 217 overlaps with the second opening 209 on the partition 205 along the height of the electrical control box 201. When the centrifugal fan 217 is working, a negative pressure is formed in the first space 206. Under the action of the negative pressure, the air in the first space 206 is drawn into the centrifugal fan 217. The air is accelerated by the blades of the centrifugal fan 217 and sent to the first opening 208 on the partition 205. Under the action of gas pressure, the air at the first opening 208 enters the first space 206 from the second space 207 through the first opening 208. The air in the first space 206 can be drawn in again by the axial fan 223, and so on, forming a stable internal circulating airflow.

[0078] Optionally, in one embodiment, the fan 203 may include an axial fan 223, which is disposed in the second space 207. In one embodiment, the axial fan 223 is disposed at the middle position of the second space 207 along the length of the electrical control box 201. When the axial fan 223 operates, it blows air into the first opening 208, thereby creating a negative pressure in the second opening 209 on the partition 205. Under the action of the negative pressure, the air in the first space 206 is drawn into the axial fan 223. The air is accelerated by the blades of the axial fan 223 and sent to the first opening 208 on the partition 205. Under the action of gas pressure, the air at the first opening 208 enters the first space 206 from the second space 207 through the first opening 208. The air in the first space 206 can be drawn into the axial fan 223 again, and so on, forming an internal circulating airflow.

[0079] It is understandable that an axial fan 223 is a fan 203 that draws air in from the center of a fan 203 and discharges it axially through a rotating impeller.

[0080] In some implementations, please refer to Figure 6 The accommodating space 204 is a single-layer space, and the electronic control module 202 includes a circuit board 224, with the fan 203 mounted on the circuit board 224.

[0081] In the above embodiments, the accommodating space 204 is a single-layer space, and the fan 203 is located on the circuit board 224. It can form an internal circulating airflow in the control box 201, which to a certain extent ensures that the internal circulating airflow can flow through all electronic components, making the temperature in the control box 201 tend to be uniform, which is conducive to the operation of the control module 202 within the normal temperature range.

[0082] Specifically, fan 203 can be axial fan 223 or centrifugal fan 217.

[0083] In one implementation, such as Figure 6 As shown, the accommodating space 204 is a single-layer space. The electronic control module 202 includes a circuit board 224, and the fan 203 is an axial flow fan 223 mounted on the circuit board 224. The air inlet of the axial flow fan 223 faces a portion of the single-layer space, and the air outlet faces another portion of the single-layer space. When the axial flow fan 223 operates, it draws in air from a portion of the single-layer space and sends it to the other portion. Under the action of gas pressure, the air in the other portion of the single-layer space flows back to the portion of the single-layer space along the height direction of the electronic control box 201, away from the air outlet of the axial flow fan 223, and is drawn in again by the axial flow fan 223. This process is repeated to form an internal circulating airflow.

[0084] In one embodiment, the accommodating space 204 is a single-layer space. The electronic control module 202 includes a circuit board 224, and the fan 203 is a centrifugal fan 217 mounted on the circuit board 224. The air inlet of the centrifugal fan 217 faces a portion of the single-layer space, and the air outlet faces another portion of the single-layer space. When the centrifugal fan 217 operates, it draws in air from a portion of the single-layer space and sends it to the other portion. Under the action of gas pressure, the air in the other portion of the single-layer space flows back to the portion of the single-layer space along the height direction of the electronic control box 201, away from the air outlet of the centrifugal fan 217, and is drawn in again by the centrifugal fan 217. This process is repeated to form an internal circulating airflow.

[0085] In one embodiment, the axial fan 223 and the centrifugal fan 217 are spaced apart from the inner wall of the electrical control box 201 and the circuit board 224 to form an air duct, through which internal circulating airflow can pass to increase the airflow velocity.

[0086] In some implementations, please refer to Figures 2 to 6 The electrical control box 201 is provided with a mounting hole 219. The electrical control assembly 200 includes a seal 220, which is located at the mounting hole 219.

[0087] In the above embodiments, the electronic control component 200 includes a sealing element 220, which is located at the mounting hole 219. The sealing element 220 has a gap 221 for wires to pass through so that the wires can be electrically connected to the electronic control module 202. This can ensure that the household appliance 100 works normally while preventing moisture and rodents from entering the electronic control box 201 to a certain extent.

[0088] Specifically, the electronic control component 200 is the core part used to control the household appliance 100. The electronic control module 202 of the electronic control component 200 needs to be electrically connected to electrical components other than the electronic control component 200 in order to control the operation of the household appliance 100.

[0089] In this embodiment of the invention, the electrical control box 201 is provided with a mounting hole 219, and a sealing member 220 can be installed in the mounting hole 219. A wire can pass through the gap 221 to connect the electrical control module 202 to other electrical components outside the electrical control box 201. When no wire passes through the sealing member 220, the gap 221 is tightly closed by the elasticity of the sealing member 220, thereby preventing moisture and rodents from entering the electrical control box 201. When a wire passes through the sealing member 220, the gap 221 is tightly fitted to the outer wall of the wire by the elasticity of the sealing member 220, thereby preventing moisture and rodents from entering the electrical control box 201 while allowing the wire to pass through and electrically connect to the electrical control module 202.

[0090] In some embodiments, the electrical control box 201 is provided with a connector that is electrically connected to the electrical control module 202.

[0091] In the above embodiment, the control box 201 is provided with a connector, which is electrically connected to the control module 202. This can ensure that the household appliance 100 works normally while preventing moisture and rodents from entering the control box 201 to a certain extent.

[0092] Specifically, the electronic control component 200 is the core part used to control the household appliance 100. The electronic control module 202 of the electronic control component 200 needs to be electrically connected to electrical components other than the electronic control component 200 in order to control the operation of the household appliance 100.

[0093] In this embodiment of the invention, the electrical control box 201 is provided with a connector, which is electrically connected to the electrical control module 202. Electrical components outside the electrical control box 201 can be connected to the connector on the electrical control box 201 through another connector, thereby realizing that the electrical control module 202 is electrically connected to the electrical components outside the electrical control box 201 through two connectors.

[0094] Understandably, the connector can provide a stable power input channel, allowing an external power source to connect to the electronic control module 202. The connector can also be used for signal transmission, transmitting control signals, data, or communication signals to the outside of the electronic control box 201 or to the electronic control module 202.

[0095] It is understood that the connectors may include, but are not limited to, power adapter interfaces, DC connectors, and USB interfaces, and they possess a certain degree of sealing capability, effectively preventing external substances such as moisture, dust, rodents, and insects from entering the electrical control box 201. The connectors can be male or female.
