Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and in particular relates to an electromagnetic cooking utensil. Background Art

[0002] Existing cooking utensils, such as electric rice cookers and pressure cookers, generally include a pot body and a pot cover. The pot body is provided with an inner pot and a heating device for heating the inner pot. The inner pot is generally made of metal. When the heating device is powered on, it can transfer heat to the inner pot to cook the rice in the inner pot. However, such cooking utensils may stick to the pot during the cooking process, making it difficult to clean the inner pot after the meal, which deteriorates the user experience.

[0003] In order to solve this technical problem, the applicant has previously applied for a moist film 0 coating technology, which sets a cooling fan on the pot body. The cooling fan operates to form a flowing airflow to cool the inner pot, so that when the high-temperature steam inside the inner pot comes into contact with the inner pot, it will quickly condense and liquidize into condensed water, forming a layer of water film between the food and the inner wall of the inner pot, preventing the food from sticking to the inner wall of the inner pot and achieving a non-stick effect.

[0004] In an electromagnetic cooking device that uses an electromagnetic coil to heat the inner pot, an electromagnetic coil and a heat preservation ring located above the electromagnetic coil are arranged inside the pot body, and the two cooperate to surround the outer periphery of the inner pot. A heat dissipation fan is arranged on one lateral side of the heat preservation ring, and an air outlet is arranged on the other side opposite to the heat preservation ring, so that a cold air flow enters from one side of the heat preservation ring, contacts the side wall of the inner pot and flows to the other side, and flows out from the other side.

[0005] This results in the temperature of the air flow close to the air inlet being lower, and the heat dissipation effect of the inner pot on this side is better. However, the temperature of the air flow on the side away from the air inlet is relatively high due to heat exchange with the inner pot, and the heat dissipation effect on this side of the inner pot is slightly worse, making the heat dissipation effect on both sides of the inner pot relatively uneven, and the non-stick effect can be further improved. Utility Model Content

[0006] The utility model provides an electromagnetic cooking utensil to solve the problem that cold air flows in from one side of a heat preservation cover and out from the other side, resulting in relatively uneven heat dissipation effect on both sides of an inner pot, and the non-stick effect can be further improved.

[0007] The technical solution adopted by the utility model is:

[0008] An electromagnetic cooking utensil comprises a pot body and an inner pot, wherein the pot body comprises an outer shell and an electromagnetic wire reel and an insulation ring located inside the outer shell, wherein the insulation ring is located above the electromagnetic wire reel, and the electromagnetic wire reel and the insulation ring form an accommodation space for placing the inner pot, wherein the electromagnetic cooking utensil further comprises a cooling fan arranged between the electromagnetic wire reel and the outer shell, wherein a vent is provided between the electromagnetic wire reel and the insulation ring, wherein at least part of the airflow blown by the cooling fan enters the accommodation space through the vent, and an exhaust port is provided between the flange of the inner pot and the edge of the pot body.

[0009] The electromagnetic cooking device of the utility model also has the following additional technical features:

[0010] The electromagnetic wire coil is provided with a support section and an avoidance section along its circumference, the upper edge of the support section is higher than the upper edge of the avoidance section, the support section abuts against the insulation ring, and the vent is formed between the avoidance section and the insulation ring.

[0011] The insulation ring is provided with a plurality of protruding supporting protrusions at intervals along its circumference, and the vent is formed between two adjacent supporting protrusions; or, the insulation ring is provided with a plurality of recessed areas at intervals along its circumference, and the recessed areas constitute the vent.

[0012] The pot body also includes a middle ring arranged on the top of the outer shell, the insulation ring is fixed to the middle ring, the insulation ring and the electromagnetic wire coil are not in contact with each other or are partially in contact with each other, so as to form the vent between the insulation ring and the electromagnetic wire coil.

[0013] The pot body is provided with a wind shield wing protruding toward and away from the accommodating space at the vent, and the wind shield wing is located above the vent to guide the airflow of the heat dissipation fan to the vent.

[0014] The bottom of the heat-insulating ring is folded in a direction away from the accommodating space to form the wind-shielding wing; or, the wind-shielding wing and the heat-insulating ring are separate structures, and the wind-shielding wing is fixed to the heat-insulating ring.

[0015] The pot body also includes a middle ring arranged on the top of the shell, the middle ring has a matching convex rib extending downward, and the matching convex rib extends to the vent to form the wind shielding wing.

[0016] The cooling fan is arranged below the electromagnetic wire reel, and an installation area is also arranged between the electromagnetic wire reel and the shell. The installation area is provided with a circuit board, and the air outlet end of the cooling fan is respectively connected with the installation area and the vent.

[0017] The electromagnetic wire reel is provided with a support wall extending along its own circumference, the support wall is located on the outside of the vent, the support wall cooperates with the insulation ring to form an air inlet channel, the air inlet channel is arranged around the accommodating space, and the vent connects the air inlet channel and the accommodating space.

[0018] The inner container comprises a bottom wall, a side wall and a transition section between the bottom wall and the side wall, and a projection of the vent toward the inner container is located in the transition section.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0020] 1. Since the electromagnetic wire coil generally corresponds to the bottom or lower side of the inner tank, the utility model sets a vent between the electromagnetic wire coil and the insulation ring, so that the cold airflow blown by the cooling fan enters the accommodating space through the vent, contacts the side or bottom of the inner tank to cool it, and then flows upward along the side wall of the inner tank, and finally is discharged from the exhaust port at the edge of the inner tank. Compared with the method of air intake on one side and air outlet on the other side, the flow path of the airflow in the utility model is from bottom to top, so that the airflow can surround the inner tank circumference, and flow through the inner tank from bottom to top, achieving full contact with the inner tank, so that the airflow temperature on both sides of the inner tank is closer, and the cooling effect on the inner tank is more uniform, which greatly improves the cooling effect and uniformity of the inner tank.

[0021] In addition, during the cooking process, the heat of the inner pot is more concentrated at the bottom, and the closer to the upper part of the inner pot, the lower the heat. Therefore, the airflow blown by the cooling fan first contacts the middle and lower part of the inner pot to cool it, which increases the priority of cooling the bottom of the inner pot, so that it contacts the cold airflow before the upper part, and then the bottom of the inner pot will start to cool down first, thereby improving the uniformity of the cooling effect of the bottom and sides of the inner pot, which helps to form a uniform water film on the inner wall of the inner pot to ensure the non-stick effect of each area. In addition, the cold airflow first contacts the middle and lower part of the inner pot to cool it. At this time, the temperature difference between the cold airflow and the inner pot is large, and the heat exchange efficiency is higher, so that the middle and lower part of the inner pot can be quickly cooled. As the airflow rises, even if the temperature of the airflow rises slightly, it can still form a better cooling effect on the upper part of the inner pot, thereby improving the uniformity of the cooling effect of the upper and lower parts of the inner pot, which helps to form a uniform water film on the inner wall of the inner pot to ensure the non-stick effect of each area.

[0022] 2. As a preferred embodiment of the utility model, the electromagnetic wire reel is provided with a support section and an avoidance section along its circumference, and the upper edge of the support section is higher than the upper edge of the avoidance section, so that the support section abuts against the insulation ring, and the vent is formed between the avoidance section and the insulation ring. The lower edge of the insulation ring abuts against the support section, and the support section provides an upward support force to the insulation ring, so that the insulation ring and the electromagnetic wire reel are stably connected, and the height of the avoidance section is relatively low, so that there is a gap between the insulation ring, and the gap constitutes a vent, and the airflow enters the accommodating space from here. In the prior art, most of the insulation rings are structurally improved, and the vent is machined and formed on the insulation ring. The insulation ring is generally made of metal material, which is difficult to process, thus increasing the cost, while the electromagnetic wire reel is usually made of plastic material, which is low in cost and easy to process. In this embodiment, the support section and the avoidance section are formed on the electromagnetic wire reel without processing the insulation ring. The vent is formed by assembling the two, which can greatly reduce the overall manufacturing cost and improve the yield rate.

[0023] 3. As a preferred embodiment of the utility model, the pot body is provided with a heat dissipation fan below the electromagnetic wire reel, and an installation area is further provided between the electromagnetic wire reel and the shell, and a circuit board is provided in the installation area, and the heat dissipation fan is connected with the installation area and the vent respectively. In this embodiment, the circuit board and the inner pot share a heat dissipation fan, that is, the heat dissipation fan bears the air cooling function of multiple components, and part of the air flow blown out flows to the installation area to cool the circuit board, and part of the air flow flows to the vent, enters the accommodating space, and contacts with the inner pot to cool the inner pot, so that one piece can be used for multiple purposes, eliminating the use of a fan, simplifying the internal structure of the pot body, and saving costs. In addition, the heat dissipation fan is located below the electromagnetic wire reel, so the air inlet can be opened on the base of the outer shell, thereby reducing the impact of the opening on the outer surface of the outer shell and improving the overall aesthetics of the electromagnetic cooking utensil.

[0024] 4. As a preferred embodiment of the utility model, the pot body is provided with a wind shield wing protruding away from the accommodating space at the vent, and the wind shield wing is located above the vent to guide the airflow of the cooling fan to the vent. When the airflow blown by the cooling fan flows to the vent, it will be blocked and guided by the wind shield wing to reach the vent, and then enter the accommodating space through the vent to cool the inner pot, so that more airflow can flow to the vent, thereby increasing the airflow used to cool the inner pot and improving the cooling efficiency.

[0025] 5. As a preferred embodiment of the present invention, the inner pot includes a bottom wall, a side wall, and a transition section between the bottom wall and the side wall, and the projection of the vent toward the inner pot is located in the transition section. The transition section is close to the bottom wall of the inner pot, and the vent faces the transition section, so that after the airflow enters the accommodating space, it first contacts the bottom of the inner pot, and the bottom of the inner pot is cooled by air, thereby improving the cooling priority of the bottom of the inner pot, helping to form a moist film on the inner wall of the bottom of the inner pot, and improving the anti-sticking effect of food.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0049] like Figure 1 , Figure 4 and Figure 7 As shown, an electromagnetic cooking utensil comprises a pot body and an inner pot 4, wherein the pot body comprises an outer shell 1 and an electromagnetic wire reel 2 and an insulation ring 3 located inside the outer shell 1, wherein the insulation ring 3 is located above the electromagnetic wire reel 2, and the electromagnetic wire reel 2 and the insulation ring 3 form an accommodating space 11 for placing the inner pot 4, the electromagnetic cooking utensil further comprises a cooling fan 5 arranged between the electromagnetic wire reel 2 and the outer shell 1, a vent 23 is provided between the electromagnetic wire reel 2 and the insulation ring 3, and the airflow blown by the cooling fan 5 at least partially enters the accommodating space 11 through the vent 23, and an exhaust port 12 is provided between the flange of the inner pot 4 and the edge of the pot body.

[0050] Optionally, the rim of the pot body is provided with a plurality of support protrusions which are arranged at intervals and protrude upward, and the flange of the inner pot 4 rests on the support protrusions, thereby forming the exhaust port 12 between two of the support protrusions.

[0051] It should be noted that, in the present invention, the cooling fan 5 can be used only to cool the inner tank 4. At this time, the airflow of the cooling fan 5 enters the accommodating space 11 through the vent 23 to cool the inner tank 4. The cooling fan 5 can also have multiple uses, for example, it can be used to cool multiple components. At this time, each component shares the cooling fan 5, so part of the airflow blown by the cooling fan 5 enters the accommodating space 11 through the vent 23 to cool the inner tank 4, and part of the airflow flows to other locations to cool other components.

[0052] Since the electromagnetic wire coil 2 generally corresponds to the bottom or lower side of the inner liner 4, the utility model sets a vent 23 between the electromagnetic wire coil 2 and the insulation ring 3, so that the cold airflow blown by the cooling fan 5 enters the accommodating space 11 through the vent 23, contacts the side or bottom of the inner liner 4 to cool it, and then flows upward along the side wall of the inner liner 4, and finally is discharged from the exhaust port 12 at the edge of the inner liner 4. Compared with the method of air intake on one side and air outlet on the other side, the flow path of the airflow in the utility model is from bottom to top, so that the airflow can surround the inner liner 4 circumference, and flow through the inner liner 4 from bottom to top, achieving full contact with the inner liner 4, so that the airflow temperature on both sides of the inner liner 4 is closer, and the cooling effect on the inner liner 4 is more uniform, which greatly improves the cooling effect and uniformity of the inner liner 4.

[0053] In addition, during the cooking process, the heat of the inner pot 4 is more concentrated at the bottom, and the closer to the upper part of the inner pot 4, the lower the heat. Therefore, the airflow blown by the cooling fan 5 first contacts the middle and lower part of the inner pot 4 to cool it, which improves the priority of cooling the bottom of the inner pot 4, so that it contacts the cold airflow before the upper part, and then the bottom of the inner pot 4 will start to cool down first, thereby improving the uniformity of the cooling effect of the bottom and side of the inner pot 4, which helps to form a uniform water film on the inner wall of the inner pot 4 to ensure the non-stick effect of each area. And the cold airflow first contacts the middle and lower part of the inner pot 4 to cool it. At this time, the temperature difference between the cold airflow and the inner pot 4 is large, and the heat exchange efficiency is higher, so that the middle and lower part of the inner pot 4 can be quickly cooled. As the airflow rises, even if the temperature of the airflow rises slightly, it can still form a better cooling effect on the upper part of the inner pot 4, thereby improving the uniformity of the cooling effect of the upper and lower parts of the inner pot 4, which helps to form a uniform water film on the inner wall of the inner pot 4 to ensure the non-stick effect of each area.

[0054] The present invention does not limit the formation method of the vent 23. As a preferred embodiment of the present invention, refer to 6 and Fig. 9 The electromagnetic wire reel 2 is provided with a support section 24 and an avoidance section 25 along its circumference, and the upper edge of the support section 24 is higher than the upper edge of the avoidance section 25, so that the support section 24 abuts against the insulation ring 3, and the ventilation hole 23 is formed between the avoidance section 25 and the insulation ring 3.

[0055] The lower edge of the insulation ring 3 abuts against the support section 24, and the support section 24 provides an upward supporting force for the insulation ring 3, so that the insulation ring 3 is stably connected to the electromagnetic wire reel 2, and the avoidance section 25 has a lower height, so that there is a gap between the insulation ring 3, and the gap constitutes the vent 23, from which the air flow enters the accommodating space 11.

[0056] In the prior art, most of the structures of the insulation ring are improved, and the vents are machined and formed on the insulation ring. The insulation ring is generally made of metal, which is difficult to process and has a low yield rate, thus increasing the cost. The electromagnetic wire reel is generally made of plastic, which is low in cost and easy to process. In this embodiment, the support section 24 and the avoidance section 25 are machined on the electromagnetic wire reel 2 without processing the insulation ring 3. The vents 23 are formed by assembling the two, which can greatly reduce the overall manufacturing cost and improve the yield rate.

[0057] Specifically, Figure 4 , Figure 5 As shown, the lower edge of the side wall 42 of the heat preservation ring 3 is provided with a reinforcing curling edge 31 to improve the overall strength of the heat preservation ring 3, and the support section 24 is provided with a contact arc surface 241, and the reinforcing curling edge 31 contacts the contact arc surface 241 to increase the contact area between the two and improve the support stability. The side of the contact arc surface 241 away from the center of the electromagnetic wire drum 2 extends upward to form a limiting protrusion 242 to prevent the heat preservation ring 3 from lateral displacement relative to the electromagnetic wire drum 2 and improve the positioning effect when the two are assembled.

[0058] It should be noted that the support section 24 may protrude from the upper surface of the electromagnetic wire reel 2 (eg Figure 6 , Fig. 9 As shown), it may also be flush with the upper surface of the electromagnetic wire drum 2, that is, the upper surface of the electromagnetic wire drum 2 constitutes the supporting section, a groove is provided on the electromagnetic wire drum 2 to constitute the avoidance section, and other areas of the electromagnetic wire drum 2 in the same circumferential direction are correspondingly higher than the groove.

[0059] Of course, the above embodiment does not mean that the present application excludes other forms of forming the vent 23. In one embodiment, the insulation ring 3 is provided with a plurality of protruding support protrusions at intervals along its circumference, and the vent 23 is formed between two adjacent support protrusions. The insulation ring 3 is supported on the electromagnetic wire reel 2 by the support protrusions, and the cold air blown by the cooling fan 5 enters the accommodating space through the space between the two support protrusions.

[0060] In another embodiment, the heat preservation ring 3 is provided with a plurality of recessed areas at intervals along its circumference, and the recessed areas constitute the vents 23. The heat preservation ring 3 abuts against the coil disk through the portion other than the recessed areas, and the cold air blown out by the cooling fan 5 enters the accommodation space through the recessed areas. Optionally, the recessed area may be a notch provided at the bottom of the heat preservation ring 3, or may be a folded edge folded in a direction close to or away from the accommodation space to guide the cold air.

[0061] As a preferred embodiment of the present invention, Figure 1 , Figure 2 As shown, the pot body also includes a middle ring 6 arranged on the top of the outer shell 1, the insulation ring 3 is fixed to the middle ring 6, the insulation ring 3 and the electromagnetic wire reel 2 are not in contact with each other or are partially in contact with each other, so as to form the ventilation hole 23 between the insulation ring 3 and the electromagnetic wire reel 2.

[0062] The “fixing” mentioned above may be a detachable fixing method such as snap-fitting, overlapping, screwing, etc., or an irremovable fixing method such as gluing, etc., and is not specifically limited here.

[0063] In this embodiment, the insulation ring 3 cooperates with the middle ring 6, so that the electromagnetic wire reel 2 has no supporting effect on the insulation ring 3, and the insulation ring 3 is in a "suspended" state relative to the electromagnetic wire reel 2, thereby forming the ventilation hole 23 between the two, and the ventilation hole 23 is a continuous circle and surrounds the accommodating space 11.

[0064] Specifically, the vent 23 can be formed between the heat preservation ring 3 and the electromagnetic wire coil 2 by moving the heat preservation ring 3 upward or moving the electromagnetic wire coil 2 downward. Figure 2 , Figure 3 As shown, the middle ring 6 is provided with a support protrusion 61 for supporting the insulation ring 3, and the upper end of the insulation ring 3 is provided with a flange, and the flange is placed on the support protrusion 61 or clamped in the gap formed between the support protrusion 61 and the upper surface of the middle ring, so that the height of the support protrusion 61 can be increased to move the position height of the insulation ring 3 upward. In another embodiment, as Figure 2 As shown, the middle ring 6 is provided with a fixing column 62 extending downward, and the electromagnetic wire drum 2 is fixed to the fixing column 62. The height of the electromagnetic wire drum 2 can be moved downward by increasing the length of the fixing column 62 or by providing a gasket at the connection between the fixing column 62 and the electromagnetic wire drum 2. The method of forming the vent 23 in this way does not require a major change to the original structure, and only requires changing the height or length of the corresponding fixing part, which is simple and convenient.

[0065] As a preferred embodiment of the present invention, Figure 1 , Figure 4 , Figure 5 As shown, the pot body is provided with a wind shield wing 32 protruding toward and away from the accommodating space 11 at the vent 23 , and the wind shield wing 32 is located above the vent 23 to guide the airflow of the cooling fan 5 to the vent 23 .

[0066] In this embodiment, the airflow blown by the cooling fan 5 flows upward along the electromagnetic wire coil 2. When the airflow flows to the vent 23, it is blocked and guided by the wind shield wing 32 to reach the vent 23, and then enters the accommodating space 11 through the vent 23 to cool the inner pot 4. Under the guidance of the wind shield wing 32, more airflow can flow to the vent 23, thereby increasing the airflow used to cool the inner pot 4, improving the cooling efficiency and the non-stick performance of the inner pot.

[0067] The wind shield wing 32 can be a structure that is inclined downward or a horizontal structure, as long as it can block the airflow below and make it flow to the vent 23, and no limitation is made here.

[0068] It should be noted that the present embodiment does not limit the formation method of the windshield wing 32, which can be one of the following embodiments:

[0069] Embodiment 1: In this embodiment, as Figure 1 , Figure 2 As shown, the bottom of the heat-insulating ring 3 is folded in a direction away from the accommodating space 11 to form the wind shield wing 32 .

[0070] Such a configuration has a simple structure, and the wind shield wing and the heat preservation ring are integrally formed, which can save the subsequent assembly steps and improve the production efficiency.

[0071] Embodiment 2: In this embodiment, as Figure 4 , Figure 6 As shown, the wind shield wing 32 and the heat preservation ring 3 are of a split structure, and the wind shield wing 32 is fixed to the heat preservation ring 3 .

[0072] In this embodiment, the wind shield wing 32 is an independent component, which can be fixed to the insulation ring 3 by means of clamping, screwing or welding, so that each component can be independently processed and manufactured, reducing the processing difficulty.

[0073] Embodiment 3: In this embodiment, the pot body further comprises a middle ring 6 arranged on the top of the outer shell 1 , and the middle ring 6 has a matching rib extending downward, and the matching rib extends to the vent 23 to form the wind shield wing 32 .

[0074] In the present embodiment, the mating rib extending downward on the middle ring 6 is folded outward at the vent 23 to form the wind shield wing 32, which can also play a role in wind shielding and drainage, allowing the airflow to flow to the vent 23. In addition, there is no need to make structural improvements to the insulation ring 3 and the electromagnetic wire reel 2. Only the middle ring 6 needs to be modified to improve applicability and adapt to more models.

[0075] As a preferred embodiment of the present invention, Figure 1 , Figure 4 As shown, the cooling fan 5 is arranged below the electromagnetic wire reel 2, and an installation area is also arranged between the electromagnetic wire reel 2 and the housing 1. The installation area is provided with a circuit board 7, and the air outlet end of the cooling fan 5 is respectively connected to the installation area and the vent 23.

[0076] In this embodiment, the cooling of the circuit board 7 and the inner pot 4 shares the cooling fan 5, that is, the cooling fan 5 is responsible for the air cooling of multiple components. A part of the airflow blown out flows to the installation area to cool the circuit board 7, and a part of the airflow flows to the vent 23, enters the accommodating space 11, and contacts the inner pot 4 to cool the inner pot 4. Thus, one piece can be used for multiple purposes, eliminating the use of a fan, simplifying the internal structure of the pot body, and saving costs. In addition, the cooling fan 5 is located below the electromagnetic wire coil 2, so the airflow inlet can be opened on the base of the outer shell 1. Compared with the opening on the side of the outer shell in the prior art, the influence of the opening on the outer surface of the outer shell 1 can be reduced, and the overall aesthetics of the electromagnetic cooking utensil can be improved.

[0077] It should be noted that the utility model does not limit the communication mode between the cooling fan 5, the vent 23 and the installation area, and it can be achieved by setting two independent air ducts, one of which connects the cooling fan 5 and the installation area, and the other connects the cooling fan 5 and the vent 23. It is also possible to not set an air duct, and use natural diversion to make part of the air flow naturally flow to the installation area, and part of the air flow naturally flow to the vent 23. For example, by setting the air outlet of the cooling fan 5 upward, the air flow naturally flows upward to the vent 23, which is not limited here.

[0078] Preferably, if Figure 1 , Figure 4 As shown, in one embodiment, the circuit board 7 is vertically arranged above the cooling fan 5, so that the circuit board 7 itself can divert the airflow blown out by the cooling fan 5, so that a part of the airflow is away from the side of the electromagnetic wire reel 2 from the circuit board 7 (1, Figure 4 The left side of the electromagnetic wire drum 2 flows upward to cool the circuit board 7, and a part of the airflow flows from the circuit board 7 toward one side of the electromagnetic wire drum 2 ( Figure 1 , Figure 4 The air flows upward (on the right side) and enters the accommodating space 11 from the vent 23.

[0079] Specifically, the cooling fan 5 can be located directly below the electromagnetic wire drum 2, that is, the two are coaxially arranged. Of course, the cooling fan 5 can also be eccentrically arranged with respect to the electromagnetic wire drum 2, which is not limited here.

[0080] In another embodiment, the cooling fan 5 is arranged on a lateral side of the electromagnetic wire reel 2, and the electromagnetic wire reel 2 has an air inlet 221 connected to the vent 23 at a position corresponding to the cooling fan 5, so that the cooling fan 5 is close to the air inlet 221, and the airflow can quickly reach the air inlet 221, thereby reducing the kinetic energy loss of the airflow and improving the cooling efficiency.

[0081] As a preferred embodiment of the present invention, Figures 7 to 9 As shown, the electromagnetic wire reel 2 is provided with a support wall 22 extending along its own circumference, and the support wall 22 is located on the outside of the ventilation port 23. The support wall 22 cooperates with the insulation ring 3 to form the air inlet channel 21, and the air inlet channel 21 is arranged around the accommodating space 11, and the ventilation port 23 connects the air inlet channel 21 and the accommodating space 11.

[0082] The support wall 22 and the insulation ring 3 form a ring-shaped air inlet channel 21. The airflow blown by the cooling fan 5 will first enter the air inlet channel 21 before entering the accommodating space 11, gather in the air inlet channel 21, and then evenly enter the accommodating space 11 through the vent 23, so that the airflow can continuously and evenly enter the accommodating space 11, improve the cooling effect and uniformity of each circumferential area of ​​the inner liner 4, and also improve the uniformity of the airflow outflowing from each vent 23. The airflow volume of each circumferential area of ​​the inner liner 4 per unit time is more uniform, thereby improving the cooling efficiency.

[0083] Preferably, in this embodiment, the ventilation holes 23 are arranged at intervals along the circumference of the inner liner 4, so that after the airflow converges in the air inlet channel 21, it flows out from each of the ventilation holes 23, thereby making the airflow contact with each circumferential area of ​​the inner liner 4 more evenly, thereby improving the cooling effect of the inner liner 4.

[0084] Furthermore, if Fig. 9 As shown, the support wall 22 has a matching groove, and the matching groove has an opening 224 facing the accommodating space 11 . When the thermal insulation ring 3 is installed on the electromagnetic wire reel 2 , the thermal insulation ring 3 closes at least a part of the opening 224 .

[0085] The mating groove has an opening 224 facing the accommodating space 11. When the insulation ring 3 is assembled with the electromagnetic wire reel 2, the insulation ring 3 closes a portion of the opening 224, so that the air inlet channel 21 is a relatively closed space, and is only connected to the accommodating space 11 through the vent 23, so that the cold air flow can converge in the air inlet channel 21 and evenly enter the accommodating space 11, thereby preventing the air flow from escaping from the air inlet channel 21 to the outside, thereby more stably and reliably delivering the cold air flow to the accommodating space 11.

[0086] Specifically, Figure 8 , Fig. 9 As shown, the support wall 22 has an extension section 222 extending upward and a matching section 223 extending laterally toward the center of the electromagnetic wire drum 2, and the two form the matching groove, so that the opening 224 of the matching groove faces the center of the electromagnetic wire drum 2. After the insulation ring 3 is assembled with the electromagnetic wire drum 2, the side wall 42 of the insulation ring 3 blocks the opening 224, and the matching section 223 contacts the side wall 42 of the insulation ring 3. The electromagnetic wire drum 2 has a support section 24 for supporting the insulation ring 3, and the support section 24 and the insulation ring 3 jointly close the opening 224.

[0087] Furthermore, if Figure 7 , Figure 8 As shown, the support wall 22 is provided with an air inlet 221 connected to the heat dissipation fan 5 , and the air inlet 221 is staggered with the vent 23 .

[0088] The air inlet 221 is opened on the support wall 22. Compared with the method of opening the air inlet on the insulation ring in the prior art, it can also reduce the processing of the insulation ring. Instead, the electromagnetic wire reel 2 with lower cost and lower processing difficulty is processed to form the air inlet 221, thereby improving the yield rate.

[0089] The air inlet 221 and the vent 23 are staggered to prevent the cold airflow entering the air inlet channel 21 at the air inlet 221 from directly entering the accommodating space 11 from the vent 23. After the airflow enters the air inlet channel 21 from the air inlet 221, it will first converge in the air inlet channel 21, and then flow into the accommodating space 11 from each of the vents 23 evenly and stably, ensuring the uniformity of the circumferential contact between the airflow and the inner liner 4.

[0090] Preferably, the air inlet 221 and the vent 23 are located at the same height and are staggered in the circumferential direction of the accommodating space 11 to reduce wind resistance and improve airflow efficiency.

[0091] It should be noted that the utility model does not limit the structure and formation method of the air inlet channel 21. In addition to the manner in which the air inlet channel 21 surrounds the accommodating space 11 as described in the above embodiment, the air inlet channel 21 can also be extended in any manner as long as the cooling fan 5 and the vent 23 can be connected.

[0092] In addition, in another embodiment, an installation space is formed between the insulation ring 3 , the electromagnetic wire reel 2 and the housing 1 , the cooling fan 5 is disposed in the installation space, and the installation space constitutes the air inlet channel 21 .

[0093] In this embodiment, the space between the electromagnetic wire drum 2, the thermal insulation ring 3 and the housing 1 constitutes the air inlet channel 21, so that no additional air duct is provided for air flow, and the air flow naturally flows into the accommodating space 11 under the action of air pressure. The air flow blown out by the cooling fan 5 first converges in the space, and then enters the accommodating space 11 through the vent 23 between the thermal insulation ring 3 and the electromagnetic wire drum 2.

[0094] As a preferred embodiment of the present invention, Fig. 9 As shown, an air inlet 221 connected to the cooling fan 5 is provided on one side of the electromagnetic wire reel 2, and the vents 23 are arranged at intervals along the circumference of the inner tank 4. The electromagnetic wire reel 2 has an air inlet end close to the air inlet 221 and a far wind end away from the air inlet 221, and the width of the vent 23 at the air inlet end is smaller than the width of the vent 23 at the far wind end.

[0095] The air inlet 221 is located on one side of the electromagnetic wire reel 2, so that the cold air flow blown by the cooling fan 5 enters the air inlet channel 21 from one side of the electromagnetic wire reel 2. Since the vents 23 close to the air inlet 221 are closer to the air flow entry position and have a larger air flow, it is easier for the air flow to enter, while the air flow at the vents 23 far from the air inlet 221 is difficult to enter. Therefore, in this embodiment, the width of the vents 23 close to the air inlet 221 is set to be smaller than the width of the vents 23 far from the air inlet 221, so as to ensure that the air flow entering each vent 23 is closer to the same, thereby improving the uniformity of heat dissipation in each area around the inner tank 4.

[0096] Specifically, the width of the air inlet 221 may gradually increase from the air inlet end to the far wind end.

[0097] As a preferred embodiment, Figure 8As shown, the inner container 4 includes a bottom wall 41 , a side wall 42 , and a transition section 43 between the bottom wall 41 and the side wall 42 , and a projection of the vent 23 toward the inner container 4 is located at the transition section 43 .

[0098] The transition section 43 is close to the bottom wall 41 of the inner pot 4, and the vent 23 faces the transition section 43, so that after the airflow enters the accommodating space 11, it first contacts the bottom of the inner pot 4, and the bottom of the inner pot 4 is cooled by air, thereby improving the cooling priority of the bottom of the inner pot 4, which helps to form a moisturizing film on the inner wall of the bottom of the inner pot 4 and improves the anti-sticking effect of food.

[0099] Specifically, the bottom wall 41 is disposed at the bottom of the inner container 4 and is a plane or a curved surface that is slightly raised toward the center and has a certain curvature, and the transition section 43 extends upward from the edge of the bottom wall 41 and connects the bottom wall 41 and the side wall 42. Preferably, the height of the transition section 43 is not greater than 3 / 4 of the total height of the inner container.
