A general IH heating (induction heating) home appliance typically includes an upper cover, a base, a coil plate and a coil bracket, an electric control main board, a radiator, an inner pot, and the like. Here, the electric control main board (generally in the form of a PCB circuit board), in particular, the power device mounted on the electric control main board such as IGBT generates a lot of heat during operation, and other heating components are provided in addition to the electric control main board. For example, an electromagnetic induction heating module generates heat by using an alternating magnetic field generated by an inductance coil plate to generate an eddy current in a magnetically conductive object placed in the magnetic field. Therefore, when the electromagnetic induction heating module is in operation, both the energized inductance coil plate and the electrical control main board generate a lot of heat. If this amount of heat cannot be efficiently and timely discharged out of the electromagnetic induction heating module, the temperature inside the device becomes too high, which affects the normal operation of the device components, and further damages the components.

That is, the horizontal bracket part and the vertical bracket part may be connected through a combination type such as a hinge connection and a hook connection, and the bracket may be formed by an integral molding method.

In one embodiment, the bracket may be a component supporting components such as a blower, a control assembly and a radiator on a heat dissipation structure, or a component for suspending or fixing a blower, a control assembly and a radiator on a heat dissipation structure, and the shape of the bracket is L-shaped can be For example, the bracket may be a bracket 600 as shown in FIGS. 1 to 4 . As can be understood, the bracket 600 shown in FIGS. 1 to 4 is only an exemplary description of the bracket, and the bracket may exist in other formats or have other names. For example, when a bracket similar to the bracket 600 shown in FIG. 1 does not exist in the heat dissipation structure, the heating module, or the cooking device, and parts such as a blower, a control assembly, and a radiator are fixed to the housing, in this case, the housing is formed on the heat dissipation structure.

For example, if the horizontal length of the radiator 300 is too long, the left end thereof may have already passed the electrical control main board, and at this time, the existing L-shaped structure is only similar to the L-shaped structure, and if there are many parts that have passed , can even be considered an inverted T. However, without a doubt, this design can also realize the purpose of the invention of the present application, and equally utilize the space under the electromagnetic induction coil plate, and likewise fall within the protection scope of the present application. Practically, due to design needs or assembly errors, there is no need to be completely vertical between the radiator and the electric control main board, and in some cases, the electric control main board is installed inclined with respect to the vertical direction and the radiator is inclined with respect to the horizontal direction. Installation is also permitted. However, if you look at the L-shaped structure from the side at this time, it is not a standard L-shape, but a partially modified L-shape, and according to actual experience, in all cases where the inclination is 30° or less, the purpose of the present application can be basically completed.

The extending direction of the air groove of the radiator 300 coincides with the radial direction of the fan 200 . In this way, the side airflow generated by the fan 200 can quickly remove heat on the radiator 300 while flowing directly through the air groove of the radiator 300 .

For example, if the horizontal length of the radiator 300 is too long, the left end may have already passed the electrical control main board 100, at this time, for reasons such as guaranteeing the support strength or alignment of the external contour, the designer needs to Accordingly, the bottom edge of the L-shaped bracket can be extended, and at this time, the existing L-shaped bracket is almost similar to the L-shaped structure, and is substantially more similar to the inverted T-shaped.

In one embodiment, except for the main part, the bracket has some accessory structures such as baffles, connecting members, mounting holes, and positioning portions, which will likewise change the specific shape of the bracket, but as a whole, the bracket is still The horizontal part and the vertical part are connected and formed.

For example, the term "inside the L-shaped structure" generally refers to being located in a region half surrounded by the L-shaped structure. Similarly, the inside of the horizontal bracket part of the bracket may mean an area close to the horizontal bracket part in the region included in the horizontal bracket part and the vertical bracket part, and the outside of the vertical bracket part of the bracket includes the horizontal bracket part and the vertical bracket part. In the region included in the part, it may mean an area close to the vertical bracket part, and the outside of the horizontal bracket part and the outside of the vertical bracket part are opposite to this.

3 to 5, the forward arrangement of the L-shaped bracket will be described as an example, and the inside of the horizontal bracket part 610 of the bracket 600 may be an area located at the top of the horizontal bracket part, and the horizontal bracket part The outside of 610 may be an area located at the lower end of the horizontal bracket part, and the inside of the vertical bracket part 620 of the bracket 600 may be an area located at the right end of the vertical bracket part, and of the vertical bracket part 620 . The outer side may be an area located at the left end of the vertical bracket part.

In one embodiment, the heating assembly may be a coil plate (eg a coil plate heated in an electromagnetic induction manner) as described above, while at the same time the heating assembly is a heating assembly that is otherwise heated (eg an electrically resistive heating assembly). heating assembly).

In one embodiment, as shown in FIG. 6 , the heating module may be an electromagnetic induction heating module, and when the heat dissipation structure is used in the electromagnetic induction heating module, the electromagnetic induction heating module includes an inductance coil plate 400 and the Including the electrical control main board 100, the inductance coil plate 400 is located above the fan 200, the inductance coil plate 400 forms a concave structure in such a way that it is wound in a spiral rise, this concave structure Guides the airflow generated by the fan 200 to flow to the electrical control main board 100 by the contour of the .

In this embodiment, the electromagnetic induction heating module further includes a concave heating coil 420 , wherein the heating coil 420 is located directly above the fan 200 , and the outer bottom and outer surface of the heating coil 420 are arcuate. A winding groove 421 is constituted by a rib-shaped rib, and the inductance coil plate 400 is wound on the winding groove 421, and a portion of the airflow formed by the fan 200 flows along the heating coil 420, FIG. Same as airflow path 1 of

As shown in Fig. 6, by using the heat dissipation structure of this embodiment, the airflow generated by the fan 200 flows along three paths. Here, in the airflow path 1, the upward axial airflow generated by the fan 200 flows along the airflow path between the inductance coil plate 400 and the support wall 413 and finally flows out from the outlet at the top of the housing 500 The airflow path 2 is the electric control mainboard 100 while the lateral airflow of the fan 200 flows along the airflow path between the support wall 413 and the L-shaped structure, and the electric control mainboard 100 from above. It bypasses and flows downward and finally flows out from the outlet 520 , and in the airflow path 3 , the lateral airflow of the fan 200 flows along the extension direction of the air groove of the radiator 300 and flows from the outlet 520 . is the outflow path.

When the heat dissipation structure of the present application is assembled to the inductance coil plate 400, the L-shaped bracket 600, the inductance coil plate 400, the fan 200, the electrical control main board 100, the radiator 300, and the air The arrangement method of the duct wall is clearly different from the conventional top-down stacking installation, and previously, the axial upward airflow not only had to complete the heat dissipation of the inductance coil plate 400, but also had to complete the electrical control main board and radiator heat dissipation. The problem was prevented, the height of the heat dissipation structure was greatly lowered, and a part of the volume could be placed under the inductance coil plate of the pot product, which greatly saves space, and provides one main assembly part, The degree of integration was improved.

The present application has completed precise control of airflow in one compact integrated structure space, and divided the airflow of the fan 200 into three parts, and the two tangential airflows are respectively generated by the electrical control main board 100 and It is used for heat dissipation of the radiator 300, and the axial airflow is used for heat dissipation of the inductance coil plate 400 (including the heating coil 420, etc.), so that the three airflows each have their own flow path. , can operate independently without interfering with each other, reducing turbulence inside the housing and reducing energy loss. The airflow flows through all the heating elements inside the housing, and the outflow paths do not overlap, so there is no so-called airflow “stagnant zone” for the heating module or even the entire housing, allowing all the airflows in the space to flow, each on its own without interfering with each other. and cooperate appropriately.

When the fan 200 is installed at a position close to the center of the lower side of the inductance coil plate 400, the space at the bottom of the inductance coil plate 400 can be fully utilized, because the air inlet of the current heat dissipation fan is mostly located on the bottom of the housing. installed, and since the height of the fan can be adjusted relatively small, if it is disposed below the inductance coil plate 400, the thickness of the electric rice cooker does not increase significantly, and at the same time, the width of the side of the housing is greatly reduced. That is, it increases the space for installing other components. And, this arrangement makes the axial outlet of the fan 200 very close to the inductance coil plate 400, so that the wind pressure loss can be minimized, so that the air flow is further along the air gap of the outer surface of the inductance coil plate 400. By allowing a good flow, heat dissipation for the entire inductance coil plate 400 can proceed better. If the inductance coil plate 400 is nearly closed, this arrangement can likewise be advantageous, and the axial airflow requires few additional parts to guide and directly supports the inductance coil plate 400 through a preset gap. It can flow into the voids between the structures 410 and flow rapidly to each part of the inductance coil plate 400 along the air duct in the actual sense composed of magnetic strips, coils, etc., and finally, the inductance coil plate 400 or It is discharged from the heating module through an outlet on the top of the support structure 410 .

The radiator 300 is installed on the side of the fan 200, effectively using the tangential airflow of the fan 200, and the hot air sent from the radiator 300 is directly discharged from the housing, and other electrical control main board 100 ) as a component, it does not blow air and does not interfere with other heat dissipation airflows, so heat dissipation continuity and effectiveness are guaranteed. In addition, in general, the air groove of the radiator 300 faces the side away from the center of the inductance coil plate 400 of the fan 200 , and the air groove of the radiator 300 is the side or side of the fan 200 . Since the height of the directional outlet is almost the same and the distance is very close, the tangential airflow of the fan 200 directly flows into the air groove of the radiator 300 with a relatively large wind pressure and air volume, thereby improving heat dissipation efficiency. Optionally, the thickness of the motor almost coincides with the thickness of the radiator, the heat dissipation fins are installed vertically, the extending direction coincides with the airflow direction, and the width of the outlet formed by the airflow guide member is approximately equal to or slightly equal to the width of the heat sink bigger In this way, when guiding the lateral airflow, most of the horizontal airflow is introduced relatively uniformly into the heat dissipation fins of the air grooves of the radiator. When the direction of the air groove of the radiator does not match the direction of the air flow, a separate guide member is required to introduce the air flow in the same direction as the air groove, and in some special cases, such as when there are special requirements for the direction of the hot air flow , you can use this method. In addition, by installing one more bottom plate under the heat dissipation fins to make the airflow more directional, heating to the bottom of the housing is prevented, and it has more integrity in appearance.

As shown in FIG. 6 , at least a portion of the radiator 300 is within the vertical projection range of the inductance coil plate 400 . That is, a substantial portion of the volume of the radiator 300 is in the space under the side of the inductance coil plate 400 . Therefore, the extra space of this part can be fully utilized, which is particularly advantageous for electric rice cooker and electric pressure cooker type products. In addition, since the radiator 300 is disposed horizontally, the upper cover plate isolates the hot air from the electric control main board and other components of the radiator, and also acts to guide the tangential air flow blown to other elements through the gap. , corresponding to further realizing the function of the air duct bottom wall by using the radiator 300, further saving space and improving the airflow passage. Of course, the so-called horizontal installation is not absolute, it should be understood as approximately horizontal, for example, if the inclination in the horizontal direction is within 5°, it falls within the allowable range. As long as the space around the coil bracket can be sufficiently utilized, the radiator 300 may be disposed on the side of the fan 200 at an angle of less than 30° with respect to the horizontal direction.

In one embodiment, the electrical control main board 100 may be installed vertically, such that the short side is below, and most elements are placed away from the bottom and bottom edge regions where the electromagnetic interference of the inductance coil plate 400 is greatest. By allowing it to be apart, it is advantageous to protect the components. In addition, in the case of an electric rice cooker type product, since the diameter of the fan is generally not larger than the length of the short side of the circuit board, when the electric control main board 100 is installed vertically, the depth of the pot body is fully utilized, and the space is maximized. can save By placing the electric control main board 100 on the radiator 300 as if it is installed at the far end of the fan 200 of the radiator 300, it constitutes an approximately L-shaped structure, as shown in FIG. It's like a bar. Of course, here both sides of the L-shaped structure may have a certain degree of inclination, since the radiator and the circuit board are installed to be inclined in certain circumstances. Therefore, the tangential airflow blown from the fan 200, except that most flows to the radiator 300, a part of the tangential airflow is the end close to the fan 200 of the radiator 300 and the inductance coil plate 400 Through the gap between the outer walls, air is blown from the bottom up to the electrical control main board and other parts of the radiator. Of course, the electric control main board 100 may be installed at other positions above the radiator 300 , and further, the surface on which the electric control main board 100 components are located may not face the fan 200 .

Of course, the so-called vertical installation is not absolute and should be understood as being approximately vertical, for example, as long as the inclination angle in the vertical direction is within 5°, it falls within the allowable range. If the space around the coil bracket can be sufficiently utilized, the electric control main board 100 may be installed on the upper portion of the radiator 300 at an angle of less than 30° with respect to the vertical direction. For example, if there is enough space on the lower side of the inductance coil plate 400, the electric control main board 100 is installed at an angle on the upper part of the radiator 300, but one end extends on the lower side of the inductance coil plate 400 Inserted, the other end can be considered to be installed within the range of possible radiators. In this way, the height occupied by the circuit board can be further reduced, and the structure can be made compact. At the same time, the heat dissipation airflow can still brush the component surfaces on the circuit board.

The L-shaped bracket 600 is used as the main assembly part of the heat dissipation structure, and the electrical control main board 100, the radiator 300, the fan 200, the air duct wall, etc. are all based on the L-shaped bracket 600 By being assembled as a , each existing scattered member is concentrated on the L-shaped bracket 600, and is integrated into one standard module with a very small size. Each member can find an installation position corresponding to itself on the L-shaped bracket 600 , and it is only necessary to directly insert and connect each member to the L-shaped bracket 600 during production. Therefore, the heat dissipation structure of the present application is very simple to assemble, the positioning accuracy between each member is very high, and the maintenance and replacement of the related member is very easy. The degree of generalization of the module can be improved, and as one general-purpose member or general-purpose module, it can be used for home appliances heated by an induction coil having an arc-shaped inner pot such as various types or models of electric rice cookers, electric pressure cookers and electric cookers, and designers can develop new products simply by completing some additional functions and product exterior, housing, and panel designs, and significantly shortens the overall machine development cycle and significantly reduces costs.

In one embodiment, the L-shaped bracket 600 further includes a bracket circumferential skeleton 630 that is installed surrounded by the inside of the horizontal bracket portion 610 and the vertical bracket portion 620 edge. The edge of the portion extending toward the outside of the bracket circumferential skeleton 630 basically matches the arc-shaped outer edge and shape of the heating coil 420, the bracket circumferential bone force 630, the electrical control main board 100, the radiator 300 and the fan 200 are surrounded together with the heating coil 420 to form one air duct chamber. According to the guidance of the circumferential skeleton, the lateral airflow of the fan 200 may be guided to the electric control main board 100 and sent out from the upper part of the air duct chamber.

Mounting ears 631 are installed on the side of the bracket circumferential frame 630, and the vertical bracket part 620 is installed inside the bracket position limiting frame 621 and the vertical bracket vertically connected to the bracket circumferential frame 630 and a window frame 622 that is formed, which facilitates positioning between the L-shaped bracket 600 and the housing 500, and reduces the weight of the bracket. After the airflow generated by the fan 200 passes through the electrical control main board 100, some airflow flows into the window frame 622 through the lateral gap of the electrical control main board 100 and may pass. . However, most of the airflow still passes through the entire electrical control mainboard 100 and then passes the upper part, and then the airflow in this part can be guided to be discharged from the housing bottom or central outlet. At this time, the heat radiation airflow with a constant wind pressure flows through the back side of the electrical control main board and takes the amount of heat from the electrical control main board, so that the heat radiation airflow emitted from the radiator does not pass through the area any longer, so that the electric control main board It does not form secondary heating in the air duct, so the installation of the air duct is very reasonable, does not interfere with each other, and does not overlap heating.

Additionally, the heat dissipation structure is installed on the horizontal bracket part 610 and surrounds the fan 200 in half, and an air duct wall structure 700 that guides the airflow generated by the fan 200 toward the radiator 300. Further including, specifically, the air duct wall structure 700 is installed on both sides of the fan 200 and includes a first air duct wall 710 and a second air duct wall 720 that are parallel to each other, It further comprises an arc-shaped third air duct wall 730 connected at both ends to the first air duct wall 710 and the second air duct wall 720, the first air duct wall 710 and the second air duct wall ( 720 also extends to either side of the radiator 300 , respectively. The airflow generated by the fan 200 is collected through the first air duct wall 710 , the second air duct wall 720 , and the third air duct wall 730 .

The direction of the heat dissipation airflow generated by the fan 200 is generally not in the desired path, so an air duct wall structure is installed to guide the airflow. In the present application, the air duct wall structure 700 mainly guides the airflow to the radiator 300 and the electrical control main board 100 . Although other elements on the electrical control main board do not generate very strong heat, they have formed a new airflow path, so the elements of this part dissipate heat more uniformly, improve heat dissipation efficiency, and effectively utilize all possible air ducts, By allowing the airflow in the module to flow sufficiently, to form a positive wind pressure around the electrical control main board and the radiator, to prevent the mutual interference of the airflows, and the blown airflow to fill the space on the back side of the circuit board, Prevents the generated hot air from flowing back into the circuit board area. Due to the interconnection of each member, the overall strength of the heat dissipation structure is improved, the appearance is neat and aesthetic, and the internal structure is compact. Of course, the structure of the air duct wall is not limited to the above, and it can be divided or integrated, far from or close to the fan blade, and various forms can be used as long as it can complete the lateral guiding function of the air flow. It is possible.

Additionally, in this embodiment, the heat dissipation structure is installed on the L-shaped bracket 600 , and further includes a support structure 410 for supporting the inductance coil plate 400 . Corresponding to the inductance coil plate 400 , the support structure 410 also has a concave shape. In one embodiment, the entire heat dissipation structure is installed on the support structure 410 .

Additionally, in this embodiment, the supporting structure 410 further includes a hollow supporting leg 411 installed on the air duct wall structure 700 and a supporting member 412 installed on the supporting leg 411, specifically As a result, the support legs 411 are installed throughout the first air duct wall 710 and the second air duct wall 720 .

In one embodiment, as shown in FIG. 7 , FIG. 7 is a schematic diagram of a combination of the inductance coil plate of the heat dissipation structure shown in FIG. 6 , the support structure and the L-shaped bracket. The support structure 410 further includes a cylindrical hollow support wall 413 installed while surrounding the support member 412 . In this way, an air flow passage is formed between the inductance coil plate 400 and the support wall 413, and an air flow passage is also formed between the support wall 413 and the L-shaped structure. to make the flow of airflow produced by

Additionally, FIG. 8 shows another structural schematic diagram of the heat dissipation structure shown in FIG. 6 . The heat dissipation structure further includes a housing 500, an opening 510 is opened at the bottom of the housing 500, and an outlet 520 toward the air groove of the radiator 300 is provided on the side of the housing 500. The L-shaped bracket 600 is installed on the housing 500 so that the mounting hole 611 and the opening 510 are installed coaxially, and also the vertical bracket part 620 and the housing 500 . The side with the outlet 520 is spaced. Additionally, a first fence 511 is installed in the opening 510 portion, and a second fence 521 is installed in the outlet 520 portion. Of course, the position of the outlet may be adjusted as needed, and for example, a corresponding outlet may be installed in the center or upper portion of the housing 500 to independently guide a plurality of airflows emitted from the fan.

Additionally, the present application includes a heat dissipation structure according to the above-described embodiment, further comprising a heating coil 420 , and the projection of the fan 200 further includes an electromagnetic induction heating module located within the projection of the heating coil 420 . to provide. The outer edge of the portion extending inside the bracket of the circumferential skeleton of the bracket 630 basically matches the shape of the outer edge of the heating coil 420 with each other, the perimeter of the bracket 630, the L-shaped bracket 600 is a heating coil Surrounded with 420 to form an air duct chamber.

In one embodiment, as shown in Figure 9, Figure 9 is an assembled perspective view of another embodiment of the electromagnetic induction heating module of the present application. The advantages of the integrated heat dissipation structure can be clearly seen through the drawing, the fan and the radiator can be hidden under the inductance coil plate 400, and the entire integrated heat dissipation structure can be supported through the L-shaped bracket 600 . ), by installing an additional bottom plate on the radiator 300 or by allowing the horizontal bracket part 610 to cover the bottom of the radiator 300, by installing an outlet in the vertical bracket, horizontal It is possible to facilitate the airflow and the ascending bifurcated airflow to be discharged from the heat dissipation structure, and the outer edge of the portion extending inside the bracket of the bracket circumferential frame 630 is basically the outer edge and shape of the heating coil 420 . These are matched with each other, and by additionally installing the blower cover 8 around the fan 200 , it is possible to make the airflow guidance more precise and accurate. Through the above design, all members of the heat dissipation structure are integrated into one organic whole, so that the structural strength can be improved, and it is closely coupled with the coil plate, so that the overall appearance is very neat and aesthetic, and the internal gas flow is independent and orderly The heat dissipation airflow does not move without direction and the heat dissipation efficiency is high.

The electromagnetic induction heating module and heat dissipation structure of the present application creatively design the heat dissipation structure of the electromagnetic induction heating module, so that the structure is compact and the integration is strong. Instead, it may be used for heat dissipation of other heat generating members (eg, inductance coil plates). The electromagnetic induction heating module and heat dissipation structure of the present application have a unique design, strong practicality, and low cost, and are used in various pot products.

In one embodiment, referring to FIGS. 10 to 17 , the heating module includes a coil plate 1 , a coil bracket 2 , an electrical control main board 4 , a blower 5 and an air duct wall structure, and , the coil plate (1) is fitted inside the coil bracket (2), and the blower (5) is installed below the bottom of the coil bracket (2), and the projection of its center is inside the projection of the coil plate (1). located, the electrical control main board 4 includes a circuit board 41 and a radiator 42, the radiator 42 is installed horizontally on the side of the blower 5, and the circuit board 41 is a radiator 42 ), and the air duct wall structure is used to guide the airflow from the blower (5) side to the electrical control main board (4) direction.

The coil bracket 2 is the main assembly part. The projection of the blower 5 is located in the projection of the coil plate 1 . The projection of the radiator 42 lies at least partially within the projection of the coil plate 1 . The projection of the circuit board 41 does not intersect the projection of the coil plate 1 .

Here, the projection may be a projection in the depth or height direction of the coil bracket 2 , that is, a projection in a plane parallel to the bottom of the coil bracket 2 .

The coil bracket 2 roughly covers the outside of the coil plate 1, and a gap 21 is formed at the bottom, and the airflow sent from the upper part of the blower 5 passes through the gap 21 to the coil bracket ( 2) is introduced into the gap between the coil plate (1) and discharged out of the module.

The blower mounting structure 25 is installed at a position close to the center of the bottom of the coil bracket 2 .

The electrical control main board 4 is approximately L-shaped, and the port of the radiator 42 air groove faces the side of the blower 5 .

A part of the airflow blown out from the side of the blower 5 is blown into the air groove of the radiator 42, and a part is blown into the circuit board 41 through the gap between the upper part of the radiator 42 and the outer surface of the coil bracket 2 is blown

The air duct wall structure further includes a bracket air duct wall 23 , and guides the airflow passing through the air gap between the upper portion of the radiator 42 and the outer surface of the coil bracket 2 to be blown to the components on the circuit board 41 . and is also discharged out of the module from the central portion or upper portion of the bracket air duct wall 23 .

The circuit board 41 may be installed on top of the radiator 42 at an angle of less than 30° with respect to the vertical direction. The radiator 42 may be installed on the side of the blower 5 at an angle of less than 30° with respect to the horizontal direction.

The above-described arrangement of the coil bracket 2, the blower 5, the circuit board 41, the radiator 42, and the air duct wall is clearly different from the conventional top-down stacking installation, and previously the axial upward airflow was The problem of not only having to complete the heat dissipation of the coil plate 1, but also having to complete the heat dissipation of the electrical control main board 4 was prevented, and the volume and difficulty of assembly were greatly reduced. Accurate airflow control is creatively completed within a fairly compact structural space, and the airflow of the blower 5 is divided into three parts, so that the two-pronged tangential airflow is generated by the circuit board 41 and Used for heat dissipation of the radiator 42, and the axial airflow is used for heat dissipation of the coil plate 1 (plate body, coil, magnetic strip, etc.) , do not interfere with each other, reduce turbulence inside the housing, and reduce energy loss. The plurality of airflows flow through all the heating elements inside the housing, fill almost all the space, and the outlet paths do not overlap, so that there is no so-called airflow “stagnant zone” in the heating module even the entire housing, so that all the airflows in the space flow and , without interfering with each other, performing their respective duties and cooperating appropriately.

When the blower 5 is installed at a position close to the center of the lower side of the coil plate 1, the space at the bottom of the coil plate 1 can be fully utilized, because the air inlet of the current heat dissipation fan is mostly installed on the bottom of the housing. In addition, since the height of the fan can be adjusted relatively small, if it is arranged below the coil plate 1, the thickness of the electric rice cooker does not increase significantly, and at the same time, the width of the side of the housing is greatly reduced. That is, it increases the space for installing other components. And, this arrangement makes the axial outlet of the blower 5 very close to the coil plate 1, so that the wind pressure loss can be reduced as much as possible, so that the airflow better flows along the air gap of the outer surface of the coil plate 1 By doing so, the heat dissipation for the entire coil plate 1 can be better progressed. If the coil bracket 2 is of the closed type, almost covering the coil plate 1 , this arrangement can likewise be advantageous, the axial airflow requiring few additional parts to be guided, directly through the gap 21 , It can be introduced into the air gap between the coil plate 1 and the coil bracket 2, and also the coil plate ( As it flows rapidly into each part of 1), it is finally discharged from the heating module through the outlet on the top of the coil plate (1).

The radiator 42 is installed on the side of the blower 5, effectively using the tangential airflow of the blower 5, and the hot air sent from the radiator 42 is directly discharged from the housing, and other circuit board 41 components As it does not blow air through the air and does not interfere with other heat dissipation airflows, heat dissipation continuity and effectiveness are guaranteed. Also, in general, the air groove of the radiator 42 faces the side away from the center of the coil bracket 2 of the blower 5, and the port of the air groove of the radiator 42 is on the side or side of the blower 5 Since the height of the directional outlet is almost the same and the distance is very close, the tangential airflow of the blower 5 directly flows into the air groove of the radiator 42 with a relatively large wind pressure and air volume, thereby improving the heat dissipation efficiency. Of course, the preferred way is that the thickness of the motor almost coincides with the thickness of the radiator, the heat dissipation fins are installed vertically, and the direction of extension coincides with the direction of the airflow. In this way, when guiding the lateral airflow, the airflow is introduced relatively uniformly into the heat dissipation fins of the air grooves of the radiator.

In addition, it is possible to further install one bottom plate under the heat dissipation fin, in this case, the flow of air flow has more directionality. When the direction of the air groove of the radiator does not match the direction of the air flow, a separate guide member is needed to introduce the air flow in the same direction as the air groove, and in some special cases, such as when there are special requirements for the direction of the hot air flow , you can use this method.

In one embodiment, contrary to the above description, since the blower can blow the air in the air duct chamber from the blower in addition to blowing external wind into the air duct chamber, the above-mentioned outlet becomes the inlet.

In one embodiment, as shown in FIG. 14 , at least a portion of the radiator 42 is within the vertical projection range of the coil plate 1 . That is, a substantial portion of the volume of the radiator 42 is in the space under the side of the coil plate 1 . Therefore, the extra space of this part can be fully utilized, which is particularly advantageous for electric rice cooker and electric pressure cooker type products. In addition, since the radiator 42 is arranged horizontally, the upper cover plate isolates the hot air from the other components of the electrical control main board 4, and also acts to guide the tangential air flow blown to the other elements through the air gap. Therefore, using the radiator 42 corresponds to further realizing the function of the bottom wall of the air duct, further saving space and improving the airflow passage. Of course, the so-called horizontal installation is not absolute, it should be understood as approximately horizontal, for example, if the inclination is within 5°, it falls within the allowable range. As long as the space around the coil bracket can be fully utilized, the radiator 42 may be disposed on the side of the blower 5 at an angle of less than 30° with respect to the horizontal direction.

The circuit board 41 is installed vertically, preferably the short side is under and the long side is on the side, but even if the long side is below, the object of the present application can be realized. When the short side is below, most elements can be far away from the bottom and bottom edge regions where the electromagnetic interference of the coil plate 1 is greatest, which is advantageous for protecting components. In the case of an electric rice cooker and an electric pressure cooker type product, when the circuit board 41 is installed vertically, the depth of the main body of the pot is fully utilized, and space can be saved as much as possible. In the present application, the circuit board 41 is placed on the radiator 42 , and the most preferable position is one end of the radiator 42 away from the blower 5 . In this way, one L-shaped structure was constructed, which, of course, is approximately L-shaped, as shown in FIG. 14 .

Here, the side shape of the electric control main board 4 has been described in an L-shape, which is to simply and clearly explain the positional relationship between the circuit board and the radiator, and the electric control main board 4 must be L when viewed from the side. It is not intended to limit the shape of a ruler, and in fact, this is impossible, because the thickness of the radiator 42 is not the same as that of the circuit board 41 , and various components are installed on the circuit board 41 . Both sides of the L-shaped structure may have a certain degree of inclination, because in certain circumstances, the radiator and the circuit board are installed inclined, and the L-shape formed at this time is not a standard L-shape. In addition, if the circuit board 41 is installed not to be in close contact with the edge of the radiator 42, for example, even if it is installed slightly away from the left edge, the entire electrical control main board 4 will not look like a standard L-shape. can However, all of these installation methods can be viewed as approximately L-shaped, and all of them can realize the object of the present application. Except that most of the tangential airflow sent from the blower 5 flows to the radiator 42, a part of the tangential airflow is between the end close to the blower 5 of the radiator 42 and the outer wall of the coil bracket 2 Through the gap, it blows from bottom to top to other parts of the electrical control main board (4). Although the heat generation of the element in that part is not very strong, since a new air flow path is formed, the heat dissipation becomes more uniform, the heat dissipation efficiency is increased, and all possible air ducts are effectively used, so that the air flow inside the housing can flow sufficiently, By forming a positive wind pressure around the electrical control main board 4 to fill the space on the back side of the circuit board, hot air generated by other heat dissipating elements is prevented from flowing back into the circuit board area.

In one embodiment, the electrical control main board 4 may be installed at another location above the radiator 42 , and furthermore, the surface on which the components of the circuit board 41 are located may not face the blower 5 . . Of course, the so-called vertical installation is not absolute and should be understood to be approximately vertical, for example, as long as the inclination is within 5°, it falls within the acceptable range. If the space around the coil bracket can be sufficiently utilized, the circuit board 41 may be installed on the upper portion of the radiator 42 at an angle of less than 30° with respect to the vertical direction. For example, if there is sufficient space on the lower side of the coil bracket 2, the circuit board 41 is inclinedly installed on the upper side of the radiator 42, and one end is extended and inserted into the lower side of the coil bracket 2, and the other end can be considered to be installed within the range of possible radiators. In this way, the height occupied by the circuit board can be further reduced, and the structure can be made compact. At the same time, the heat dissipation airflow can still brush the component surfaces on the circuit board.

In the heating module, the coil bracket 2 can be used as the main assembly.
