[0002] The wire reel is one of the heating elements of electromagnetic heating. At present, the main method of heat dissipation for the wire reel is fan convection heat exchange. For conventional general-purpose wire reels, such as simple regular shapes such as round and rectangular structures, this method can meet the basic temperature rise requirements of the wire reel. However, for wire reels with a large heating area, only the fan or the addition of a wind shield structure to guide the air can only achieve heat dissipation in the part directly blown by the fan. The air volume is small in the part far from the fan, and the temperature of the wire reel is still high, which poses a safety risk. Therefore, this method cannot meet the overall heat dissipation requirements of the wire reel. Utility Model Content

[0026] In order to solve the problem of poor heat dissipation effect of the wire reel in the prior art, the main purpose of the utility model is to provide a heat dissipation structure and a cooking utensil, wherein the cooking utensil includes the following heat dissipation structure.

[0027] Embodiment 1

[0028] like Figures 1 to 6 A heat dissipation structure shown includes a base 10, a wire coil 20 for heating a pot body, and a heat sink 30. The base 10 and the wire coil 20 together form a closed cavity, and the wire coil 20 serves as a partial side wall of the cavity. The cavity has an air inlet 13 and an air outlet 14; the heat sink 30 is connected to the air inlet 13 and transports gas into the air inlet 13.

[0029] In this embodiment, a base 10 and a wire drum 20 are provided, and the base 10 and the wire drum 20 together form a closed cavity, and the cavity has no other openings except the air inlet 13 and the air outlet 14, so that the gas delivered by the air inlet 13 of the heat sink 30 is restricted to flow in the cavity and flow out from the air outlet 14, and the wind field flow is restricted to be located only between the wire drum 20 and the base 10, so that the gas can always flow through the wire drum 20 to take away the heat of the wire drum 20, thereby improving the overall heat dissipation effect of the wire drum 20. Compared with the free flow of gas in the traditional open cavity, it avoids the gas flowing along other invalid paths, resulting in low airflow utilization, thereby affecting the heat dissipation effect of the wire drum 20. Moreover, by reasonably setting the air inlet 13 and the air outlet 14, the gas flow direction is changed, and the heat dissipation of different high-temperature parts of the wire drum 20 can be achieved in a targeted manner.

[0030] It should be noted that the closedness mentioned in this embodiment means that the cavity has no other inlet and outlet except the air inlet 13 and the air outlet 14. After the gas enters the cavity through the air inlet 13, it can only be discharged from the air outlet 14. The up and down direction of this embodiment refers to the axial direction of the pot body. Since the pot body of this embodiment is placed longitudinally so that the axis of the pot body is vertical, the up and down direction is actually the height direction, that is, Figure 2 The up and down directions in .

[0031] like Figure 1 , Figure 2 As shown, in this embodiment, the base 10 includes a closed portion 11 and a shell portion 12. The closed portion 11 and the wire drum 20 are both located in the shell portion 12. The closed portion 11 has a first open side 111 and a second open side 112. The open portion here means that the closed portion does not enclose a complete cavity. In the open part, the wire drum 20 and the shell portion 12 are used to shield the above-mentioned open side. That is, the wire drum 20 is located at and shields the first open side 111, and a part of the shell portion 12 is located at and shields the second open side 112. In this way, the wire drum 20, the closed portion 11, the shell portion 12 and the wire drum 20 together form a complete cavity. In this way, on the one hand, the structural composition of the closed portion 11 can be reduced, and the number of required components can be reduced. On the other hand, since the wire drum 20 participates in the formation of the cavity, the airflow can directly act on the wire drum 20 after entering the cavity, thereby directly taking away the heat of the wire drum 20. The setting of the closed cavity makes the heat dissipation efficiency of the wire drum 20 higher.

[0032] In this embodiment, if Figure 2As shown, since the wire drum 20 of the present embodiment is arranged on the first open side 111, the first open side 111 is substantially located on the upward surface of the upper area of ​​the cavity, and considering that the shape of the wire drum 20 is generally arranged to match the shape of the bottom and the side of the pot body, the wire drum 20 is generally arc-shaped, and therefore the first open side 111 is also arranged in the present embodiment to be an arc-shaped extended structure. The pot body is located at the first open side 111, and the wire drum 20 is located between the first open side 111 and the pot body. In this way, the shape structure of the first open side 111 is adapted to the wire drum 20 and the pot body, so that the three can better cooperate with each other, ensuring efficient heat dissipation of the wire drum 20, and at the same time the closed portion 11 can also play a certain supporting role for the wire drum 20.

[0033] In this embodiment, the closed portion 11 has an L-shaped structure, the inner side of the L-shaped structure, that is, the semi-enclosed area formed by the two sides of the L-shaped structure forms an installation area, the pot body is located in the installation area, and the first open side 111 is located on the side of the installation area. In this way, the inner side of the L-shaped structure is the first open side 111, and the outer side of the L-shaped structure is the second open side 112. The inner side surface of the L-shaped structure can be in the form of an arc, so that the first open side 111 can form the aforementioned arc-shaped extended structure, and the outer side surface of the L-shaped structure can cooperate with the inner wall surface of the shell portion 12, so that the bottom wall and side wall of the L-shaped structure can be stably and reliably connected to the shell portion 12.

[0034] Generally speaking, the shell part 12 of this embodiment is cylindrical in shape, and a recess is provided in the middle thereof for installing the wire drum 20 and the pot body. The closed part 11 has a plurality of side panels, which may include a left side panel, a right side panel, a front side panel and a support panel, wherein the left and right side panels are relatively arranged on both sides of the cavity, and the left and right side panels of this embodiment are vertically arranged, and the left and right side panels are L-shaped. The front side panel is longitudinally arranged on one side of the left and right side panels close to the bottom of the pot body, and the front side panel can be provided with an air outlet 14 as required, and the support panel is arranged above the inner side of the L-shaped left and right side panels, and the support panel is in contact with the wire drum 20, thereby playing the role of auxiliary support for the wire drum 20 to ensure the installation reliability of the wire drum 20, and the top of the left and right side panels can be provided with a plate or not as required, and the air outlet 14 can also be provided at this position as required. Of course, the specific structural form of the closed part 11 can be adjusted as required.

[0035] In this embodiment, there are multiple air outlets 14, so that the gas can be guided to the multiple air outlets 14, and heat dissipation in multiple directions is achieved, which is beneficial to the uniform heat dissipation of the wire drum 20, and avoids the occurrence of dead corners in the cavity, which causes the part of the wire drum 20 to be hot due to the non-flow of gas or poor fluidity. In this embodiment, there is only one air inlet 13, which is arranged at the bottom surface of the shell part 12, that is, at the bottom surface of the closing part 11, which is beneficial to the smooth flow of airflow and avoids the airflow turbulence caused by multiple air inlets.

[0036] like Figure 4 As shown, preferably, the heat dissipation structure further includes an air guide plate 40, which is arranged in the cavity and diverts the airflow in the cavity to different air outlets 14. In this way, the air guide plate 40 can divert the gas flowing into the cavity and distribute the air volume in a targeted manner to better dissipate the heat of the high-temperature parts of the wire drum 20. For example, more gas can be diverted to the high-temperature parts of the wire drum 20, thereby accelerating the heat dissipation speed of the high-temperature parts and improving the heat dissipation effect of the high-temperature parts of the wire drum 20. With the arrangement of multiple air outlets 14, the diverted airflow can be discharged from different air outlets 14 respectively, so that each airflow path can achieve stable heat dissipation.

[0037] In this embodiment, at least two of the top surface, the side surface and the bottom surface of the cavity are provided with air outlets 14, such as Figure 2 As shown, the top and bottom surfaces of the cavity of this embodiment are both provided with air outlets 14, that is, air outlets 14 are provided at both ends of the L-shaped structure, that is, air outlets 14 are provided at the top and front side panels of the left and right side panels of the closed portion 11, respectively. The air guide plate 40 is arranged at the air inlet 13 at an angle relative to the axis of the air inlet 13, and the air guide plate 40 is arranged in a thin sheet shape, so that the air guide plate 40 plays a role in guiding and distributing the air volume, thereby diverting the airflow at the air inlet 13 to the air outlet 14 on the top surface of the cavity and the air outlet 14 on the side surface of the bottom of the cavity. It should be noted that the bottom surface of the cavity refers to the bottom side surface of the closed portion.

[0038] In order to ensure effective airflow diversion, the top of the air guide plate 40 of this embodiment is set to be at a relatively short distance from the wire drum 20, thereby ensuring the diversion effect. In order to match the arc-shaped arrangement of the wire drum 20, the air guide plate 40 of this embodiment is close to one end of the wire drum 20, that is, the top of the air guide plate 40 is set to be arc-shaped to match the shape of the wire drum 20, so that it can be as close to the bottom surface of the wire drum 20 as possible.

[0039] Preferably, the inclination angle of the air guide plate 40 relative to the axis of the air inlet 13 can be adjusted, so that the air volume can be freely distributed according to the actual temperature rise of the wire drum 20.

[0040] In this embodiment, the heat dissipation structure has a longitudinal section passing through the symmetry axis of the cavity, that is, Figure 3 The vertical plane extending from front to back and located at the center of the left and right sides, that is, Figure 3 The dotted line in the figure is located on the top surface and / or side surface of the cavity, and the longitudinal section passes through the air outlet 14. In other words, the air outlet 14 can be set at the top of the left and right side panels of the closed part 11 and the center of the front side panel to guide the gas to flow evenly through the cavity. Of course, the number and position of the air outlet 14 can be adjusted as needed, and the air outlet 14 can be set at other positions according to the temperature rise of the wire drum 20, which can reasonably guide the gas flow and improve the heat dissipation effect.

[0041] In this embodiment, based on the L-shaped structure of the enclosed portion 11, the air inlet 13 is arranged at the bottom surface of the cavity, that is, the bottom surface of the enclosed portion 11 and the bottom corner of the L-shaped structure, so as to balance the path length of the gas flowing to the two air outlets 14, and improve the heat dissipation effect of the cable drum 20. Correspondingly, the heat sink 30 is located at the bottom of the base 10 and is connected to the air inlet 13, that is, the heat sink 30 is arranged at the air inlet 13, so that it is convenient for it to transport external gas into the cavity to dissipate heat for the cable drum 20. Optionally, the heat sink 30 can use a fan.

[0042] Embodiment 2

[0043] Different from the first embodiment, the configuration of the closing portion 11 and the shell portion 12 of this embodiment is different, the cavity is formed by the wire drum 20 and the closing portion 11, and the shell portion 12 is not used as a part of forming the cavity.

[0044] Specifically, similar to the first embodiment, the base 10 of this embodiment includes a closed portion 11, and the closed portion 11 and the wire drum 20 together form a closed cavity. The closed portion 11 has a first open side 111, and the wire drum 20 is located on and blocks the first open side 111. Different from the first embodiment, the closed portion 11 of this embodiment does not have a second open side 112, and the second open side 112 is closed by the closed portion 11 itself, so that the formation of the closed cavity does not rely on the shell portion 12. At this time, the closed portion 11 and the shell portion 12 can be arranged at intervals. In this way, the closed portion 11 can also include a rear side plate, which is arranged opposite to the front side plate, and the rear side plate is arranged at the second open side 112 in the first embodiment, so as to block the second open side 112. The arrangement of the air inlet 13 and the air outlet 14 can be the same as that of the first embodiment, except that an additional inlet needs to be arranged on the shell portion 12, and the inlet is connected to the air inlet 13 through the air duct, so as to achieve the effect of the heat sink 30 entering the cavity.

[0045] Embodiment 3

[0046] The difference from the first embodiment is that the specific structure of the sealing portion 11 is different.

[0047] like Figure 5 As shown, in this embodiment, based on the different settings of the wire drum 20, the specific shape and size of the closed portion 11 are adjusted on the basis of the solution of the first embodiment. In this embodiment, the area of ​​the wire drum 20 at the bottom of the pot body is relatively small, and it is mainly arranged on the side of the pot body. Therefore, at this time, the length of the closed portion 11 extending laterally at the bottom of the pot body can be reduced accordingly, so that the first open side 111 on the inner side of the L-shaped structure can cover the entire inner side of the L-shaped structure, and the size of the first open side 111 matches the size of the wire drum 20, thereby ensuring that the docking area between the first open side 111 and the wire drum 20 is adapted, thereby ensuring the heat dissipation effect. Of course, even if the setting method of this embodiment, the method of the first embodiment can also be adopted. Figure 1 The setting of the closing portion 11 in Figure 5 The closing portion 11 in the pot body extends laterally for a long distance at the bottom of the pot body.

[0048] Taking into account the size of the wire reel 20 located at the bottom of the pot body in this embodiment, the air outlet 14 is not set at the front side panel in this embodiment, but only at the top ends of the left and right side panels. In addition, an upper side panel is added to the top ends of the left and right side panels in this embodiment. The upper side panel can partially cover the openings at the top ends of the left and right side panels, so that at least one air outlet 14 is formed at the upper side panel. In this embodiment, a large air outlet 14 is formed at the upper side panel. Of course, more air outlets 14 can also be set.

[0049] Embodiment 4

[0050] Different from the first embodiment, the air outlet 14 of this embodiment is arranged at a different position.

[0051] like Figure 6 As shown, there are multiple air outlets 14, and the top surface and / or side surface of the cavity are provided with multiple air outlets 14, and the air outlets 14 are located on opposite sides of the longitudinal section. In this embodiment, multiple air outlets 14 are respectively provided at the top of the left and right side panels and the front side panel. Taking two air outlets as an example, in this embodiment, one air outlet 14 is respectively provided between the front side panel and the left side panel and between the front side panel and the right side panel, and the two air outlets 14 are symmetrically provided with respect to the longitudinal section. The longitudinal section is Figure 6 Similarly, an upper side panel is added at the top of the left and right side panels, and an air outlet 14 is respectively arranged between the upper side panel and the left side panel and between the upper side panel and the right side panel. In this way, two air outlets 14 are respectively arranged at the top and bottom sides of the closed portion, thereby preventing the airflow from flowing only in the middle position where the longitudinal cross-section is located, and the airflow can flow dispersedly at the edge, which is beneficial to the heat dissipation of the edge of the wire drum 20.

[0052] It should be noted that, the multiple in the above embodiments refers to at least two.

[0053] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0054] 1. Solve the problem of poor heat dissipation effect of the wire reel in the prior art;

[0055] 2. Improve the overall heat dissipation effect of the cable tray, avoid the gas flowing along an invalid path, resulting in low airflow utilization, which affects the heat dissipation effect of the cable tray;

[0056] 3. By reasonably setting the air inlet and outlet, the gas flow direction can be changed, and the heat dissipation of different high-temperature parts of the wire reel can be achieved in a targeted manner.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
