Technical Field
[0001] The utility model relates to the field of air fryers, in particular to an air fryer with a heat preservation function. Background Art
[0002] In the existing air fryer, a hot air circulation component is arranged above the assembly cavity, and the heat of the heating tube is circulated by the fan and blown onto the food to heat the food for cooking. After cooking, if the food is not eaten in time, the temperature of the food will drop and become cold, which will affect the taste of the food.
[0003] To provide heat preservation for food, the existing patent CN219206508U discloses a cooking pot body. A heating film is attached to the outer wall of the pot body. The pot body can be used separately from the cooking machine or stove for heat preservation, which is beneficial to the heat preservation after food cooking and ensures that the user has a better taste when eating the food. The above-mentioned heating film needs to work in cooperation with the detection of the mutual inductance element and the induction element, and the structure is complex. Moreover, the user needs to adjust the position of the rotary handle to make the heating film work, and the operation is cumbersome. In addition, during the cooking stage, the heating film does not work, and an additional heating structure needs to be set on the pot body to heat the pot body to achieve normal cooking, resulting in a complex overall structure and high cost of the whole machine. Moreover, the heating film cannot provide additional heat to heat the food materials during the cooking stage, which limits the heating efficiency and heating uniformity of the food materials. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an air fryer with a heat preservation function, so as to solve the problem that the existing cooking pot body needs to be provided with two heating elements for use in the cooking stage and the heat preservation stage respectively, resulting in a complex overall structure, high cost and low utilization rate of the heating elements.
[0005] An air fryer with a heat preservation function disclosed by the utility model includes a machine body with an assembly cavity and a fryer assembly detachably installed in the assembly cavity. The fryer assembly includes a pot body and a heat preservation cavity integrally connected to the pot body. A heating element is arranged in the heat preservation cavity.

[0008] The heat preservation cavity is provided with a built-in power supply, and in the second state, the built-in power supply supplies power to the heating element.
[0009] The built-in power supply is a rechargeable power supply. When the first coupler and the second coupler are plugged and coupled, an external power supply charges the built-in power supply.
[0010] The heating element is fixed on the bottom wall of the pot body, the built-in power supply is arranged at the bottom of the heat preservation cavity, and the built-in power supply and the heating element are arranged at intervals.
[0011] A heat insulation member is arranged between the built-in power supply and the heating element.
[0012] The working voltage of the built-in power supply does not exceed 36V.
[0013] The deep fryer assembly includes a cover body arranged below the pot body. The cover body has an opening at the top. The cover body and the bottom wall of the pot body enclose a heat preservation cavity.

[0014] The bottom wall of the heat preservation cavity is provided with an upwardly concave mounting opening. The first coupler is arranged in the mounting opening, and a sealing member is arranged between the first coupler and the mounting opening.
[0015] The bottom wall of the heat preservation cavity is provided with support ribs. In the second state, the deep fryer assembly is placed on the tabletop through the support ribs.
[0016] Due to the adoption of the above technical solutions, the utility model has the following beneficial effects:
[0017] 1. The air fryer with a heat preservation function of the utility model can solve the problems that in the existing pot body, in addition to the heating film for heat preservation, an additional heating element needs to be arranged for use during cooking, resulting in a complex overall structure, high cost and low utilization rate of the heating element. That is, the heating element in this application is common for cooking and heat preservation, and only one heating element can meet various heating requirements, with a simple structure and low cost, enriching the usage scenarios of the deep fryer assembly; during the normal cooking process, the heating element is used to assist in heating the bottom of the food, and combined with the heating of the hot air component at the top of the original assembly cavity of the air fryer, the heating uniformity of the upper and lower surfaces of the food can be improved, ensuring uniform coloring of the food and better taste; after the food cooking is completed and the deep fryer assembly is taken out of the assembly cavity, the heating element can be used to keep the food warm, which is beneficial to maintaining the food at a suitable eating temperature, and the taste of the food can be guaranteed when the user eats at any time, improving the user experience.
[0018] Among them, the pot body is provided with an integrated heat preservation cavity for installing the heating element, which has a simple structure. Moreover, the non-exposed heating element is beneficial to the aesthetics, can reduce heat loss, and can prevent the heating element from being soaked and damaged during the cleaning of the pot body, ensuring its service performance and lifespan.
[0019] 2. As a preferred embodiment, in the second state, the first coupler is plugged and electrically connected to an external power source. When the deep fryer assembly is used alone, the external power source can cooperate with the first coupler to be powered on, so that the heating element can be powered on and work. In this way, the first coupler can be used in both the first state and the second state, improving its utilization rate and eliminating the need to set up an additional structure for supplying power to the heating element.
[0020] 3. As a preferred embodiment, an internal power source is provided in the heat preservation cavity. In the second state, the internal power source supplies power to the heating element. By setting up a dedicated internal power source for supplying power to the heating element, it can be ensured that after the deep fryer assembly is separated from the assembly cavity, the heating element can be used normally to keep the food warm, and the deep fryer assembly can be used as an independent appliance, enriching the usage functions of the deep fryer assembly.
[0021] As a preferred example of this embodiment, the internal power source is a rechargeable power source. When the first coupler and the second coupler are plugged and coupled, the external power source charges the internal power source. Thus, in the first state, the internal power source is charged by plugging the first coupler and the second coupler, which not only saves charging time but also ensures that the internal power source has sufficient power to supply the heating element after the subsequent deep fryer assembly is taken out, improving the reliability of the heating element to keep the food warm. Moreover, by using a rechargeable power source, there is no need to route wires when the deep fryer assembly is used alone, and the deep fryer assembly can be placed randomly, enhancing the convenience of use.
[0022] 4. As a preferred example, the heating element is fixed on the bottom wall of the pot body, and the internal power source is arranged at the bottom of the heat preservation cavity, with the internal power source and the heating element arranged at intervals. By arranging the internal power source and the heating element at intervals, the influence of the heat radiation of the heating element on the internal power source can be reduced, so as to avoid overheating of the internal power source and affecting its service life. Moreover, the heating element is arranged close to the bottom wall of the pot body, so that its heat can be closer to the ingredients in the pot body, improving the heating efficiency.
[0023] Furthermore, a heat insulation member is provided between the internal power source and the heating element. By setting up a heat insulation member to form a physical isolation, the heat of the heating element can be effectively prevented from reaching the internal power source and causing the internal power source to have too high a temperature rise, which is beneficial to extending the service life of the internal power source.
[0024] 5. As a preferred embodiment, the operating voltage of the built-in power supply does not exceed 36V. Adopting a relatively small operating voltage during the heat preservation stage can prevent accidents such as electric leakage and electric shock, and improve the use safety.
[0025] 6. As a preferred implementation manner, the fryer assembly includes a cover body disposed below the pot body. The top of the cover body is open, and a heat preservation cavity is formed by enclosing the bottom wall of the cover body and the pot body. The top edge of the cover body is provided with an outwardly extending turned-up edge, and the turned-up edge is fixedly connected to the bottom wall of the pot body. By using the turned-up edge to fit the bottom wall of the pot body, heat loss caused by gaps between the cover body and the pot body can be prevented, and the heating efficiency of the heating element for the food materials can be ensured.
[0026] 7. As a preferred implementation manner, the bottom wall of the heat preservation cavity is provided with an upwardly concave mounting opening, the first coupler is disposed in the mounting opening, and a sealing member is provided between the first coupler and the mounting opening. By providing a sealing member at the installation position of the first coupler, water on the tabletop where the pot body is placed or water during the cleaning process of the pot body can be prevented from entering the heat preservation cavity through the mounting opening and damaging the electronic devices in the heat preservation cavity, and the overall use performance and service life of the fryer assembly can be improved.
[0027] 8. As a preferred implementation manner, the bottom wall of the heat preservation cavity is provided with support ribs. In the second state, the fryer assembly is placed on the tabletop through the support ribs. By using the support ribs to isolate the heat preservation cavity from the tabletop, the tabletop can be prevented from being burned by high temperature. Description of the Drawings

[0043] As Figures 1 to 5 shown, the present application provides an air fryer with a heat preservation function, which includes a body provided with an assembly cavity 10 and a fryer assembly 11 detachably installed in the assembly cavity 10. The fryer assembly 11 includes a pot body 12 and a heat preservation cavity 13 integrally connected to the pot body 12. A heating element 14 is provided in the heat preservation cavity 13, and the heat preservation cavity 13 is provided with a first coupler 15 electrically connected to the heating element 14. The body is provided with a second coupler 16. The fryer assembly 11 has a first state for use placed in the assembly cavity 10 and a second state for use taken out of the assembly cavity 10. In the first state, the first coupler 15 and the second coupler 16 are plugged and coupled, and the heating element 14 is powered on to heat the pot body 12. In the second state, the heating element 14 is powered on to keep the pot body 12 warm.
[0044] The air fryer with heat preservation function of the present application can solve the problem that the existing pot body needs to be provided with an additional heating element for use during cooking in addition to the heating film for heat preservation, which leads to a complex structure of the whole machine, high cost and low utilization rate of the heating element. That is, the heating element 14 of the present application is common during cooking and heat preservation, and only one heating element 14 is needed to meet various heating needs. It has a simple structure and low cost, and enriches the use scenarios of the fryer assembly 11; during normal cooking, the heating element 14 is used to assist in heating the bottom of the food, and the heating of the hot air assembly on the top of the original assembly cavity 10 of the air fryer can improve the uniformity of heating the upper and lower surfaces of the food, and ensure that the food is evenly colored and has a better taste; after the food is cooked, the fryer assembly 11 is removed from the assembly cavity 10, and the heating element 14 can be used to keep the food warm, which is conducive to maintaining the food at a suitable eating temperature. The taste of the food can be guaranteed when the user eats it at any time, which can improve the user experience. The pot body 12 is provided with an integrated insulation cavity 13 for installing the heating element 14, which has a simple structure, and the heating element 14 is not exposed, which is not only beneficial to the aesthetics, but also can reduce heat loss. When the pot body 12 is cleaned, it can also prevent the heating element 14 from being soaked and damaged, thereby ensuring its performance and life.
[0045] In a preferred embodiment of the present application, the fryer assembly 11 of the present application can be used as an independent appliance in addition to providing a food insulation function. For example, when the fryer assembly 11 is separated from the assembly cavity 10, it can be used as an electric cooker to achieve functions such as steaming, boiling, and frying, thereby enriching its performance. When the fryer assembly 11 is used alone, the first coupler 15 can be plugged in with an external power source to achieve power supply, and the built-in power supply 19 in the insulation cavity 13 can also be used to provide power to ensure the normal use of the heating element 14, thereby improving the reliability of use.
[0046] In one embodiment, if Figure 1 As shown, the air fryer is, for example, a flip-top air fryer, the first coupler 15 is arranged at the lower end of the heat preservation chamber 13, and the second coupler 16 is arranged at the bottom of the assembly chamber 10, so that when the fryer assembly 11 is placed into the assembly chamber 10 from top to bottom, the first coupler 15 and the second coupler 16 can be conveniently plugged in. Further, the head portion of the air fryer is provided with a hot air assembly including a hot fan 18 and a heating pipe 17, and is also provided with a motor for driving the hot fan 18. When the head cover is closed, the hot air assembly can extend into the pot body 12. During the cooking process of the pot body 12, the food is heated simultaneously by the heating pipe 17 above the food and the heating element 14 below, which can improve the uniformity of heating the food.
[0047] In another embodiment, the air fryer is, for example, a drawer - type air fryer. The first coupler 15 can be arranged on the side wall of the heat preservation cavity 13, and the second coupler 16 can be arranged on the side wall of the assembly cavity 10 corresponding to the first coupler 15. In this way, when the fryer assembly 11 is horizontally pushed into the assembly cavity 10, it is convenient for the first coupler 15 and the second coupler 16 to be plugged in.
[0048] It should be noted that the heat preservation cavity 13 of the present application is not limited to being arranged below the pot body 12. The heat preservation cavity 13 can also be arranged on one side of the pot body 12, or around the outer peripheral wall of the pot body 12, and can be set according to actual needs.
[0049] As a preferred implementation manner, in the second state, the first coupler 15 is plugged and electrically connected to an external power supply. When the fryer assembly 11 is used alone, the external power supply can be used in cooperation with the first coupler 15 to be powered on, so that the heating element 14 is powered on and works. In this way, the first coupler 15 can be used in both the first state and the second state, which can improve its utilization rate and there is no need to set up an additional structure for supplying power to the heating element 14.
[0050] Specifically, the first coupler 15 can adopt a general model so that the first coupler 15 can be adapted to the second coupler 16 and an external coupler. In some embodiments, in order to improve the reliability of the use of the heating element 14, an internal power supply 19 capable of supplying power to the heating element 14 is also arranged in the heat preservation cavity 13. As a second option, the user can choose to make the first coupler 15 cooperate with the external power supply to power on the heating element 14 according to the usage habit, or control the internal power supply 19 to power on the heating element 14; and when the first coupler 15 fails, the heating element 14 can still be powered by the internal power supply 19 to ensure that the heating element 14 can be used normally.
[0051] As a preferred implementation manner, an internal power supply 19 is arranged in the heat preservation cavity 13. In the second state, the internal power supply 19 supplies power to the heating element 14. As Figures 1 to 3 shown, by arranging the internal power supply 19 specifically for supplying power to the heating element 14, it can be ensured that after the fryer assembly 11 is separated from the assembly cavity 10, the heating element 14 can be used normally to keep food warm, and the fryer assembly 11 can be used as an independent appliance, enriching the usage functions of the fryer assembly 11.
[0052] In some embodiments, the internal power supply is a rechargeable power supply 20. When the first coupler 15 and the second coupler 16 are plugged and coupled, the external power supply charges the rechargeable power supply 20.
[0053] When using the rechargeable power supply 20, the rechargeable power supply 20 is pre-charged to have sufficient power, so that it can be used immediately when the fryer assembly 11 is taken out. The fryer assembly 11 does not require an external circuit, which facilitates its flexible movement and placement, and improves the convenience of use. Preferably, as Figure 2 shown, a button switch 21 is provided on the side wall of the heat preservation cavity 13, for example, to control the heating element 14 to work and cut off the power.
[0054] As Figure 4 shown, it is the electrical control schematic diagram of the heating element 14 in the first working state. During the cooking stage, the household power supply is connected by the power cord. Under the condition that the first coupler 15 and the second coupler 16 are plugged and coupled, the external power supply can not only supply power to the heating tube 17 of the hot air assembly and the heating element 14 to make them work, but also charge the rechargeable power supply 20. In this way, not only can the charging time be saved, but also it can be ensured that the rechargeable power supply 20 has sufficient power to supply power to the heating element 14 after the fryer assembly 11 is taken out later, so as to improve the reliability of the heating element 14 to keep the food warm. As Figure 5 shown, it is the electrical control schematic diagram of the heating element 14 in the second working state. During the heat preservation stage, by starting the button switch 21, the rechargeable power supply 20 can be controlled to discharge and supply power to the heating element 14, so that the heat of the heating element 14 keeps the food warm.
[0055] In some other embodiments, the built-in power supply is the rechargeable power supply 20, and an interface is provided on the side wall of the heat preservation cavity 13, and the rechargeable power supply 20 can be charged by connecting an external circuit at the interface.
[0056] In addition to using the above-mentioned rechargeable power supply 20, in other embodiments, the built-in power supply can adopt a non-rechargeable battery. When the battery power is exhausted, the battery can be replaced in time to ensure the power supply to the heating element 14.
[0057] It can be understood that in other embodiments, an interface is provided on the side wall of the heat preservation cavity 13, and the heating element 14 can be powered on by connecting an external power cord at the interface.
[0058] In the embodiment where the built-in power supply 19 is provided in the heat preservation cavity 13, as a preferred embodiment, the heating element 14 is fixed on the bottom wall of the pot body 12, and the built-in power supply 19 is arranged at the bottom of the heat preservation cavity 13, and the built-in power supply 19 and the heating element 14 are arranged at intervals.
[0059] As Figure 1 shown, by arranging the built-in power supply 19 and the heating element 14 at intervals, the influence of the heat radiation of the heating element 14 on the built-in power supply 19 can be reduced, so as to prevent the built-in power supply 19 from overheating and affecting its service life; moreover, the heating element 14 is arranged close to the bottom wall of the pot body 12, so that its heat can be closer to the ingredients in the pot body 12, thereby improving the heating efficiency.
[0060] In some examples, a heat insulator is provided between the built-in power supply 19 and the heating element 14. By providing the heat insulator to form a physical isolation, it can effectively prevent the heat of the heating element 14 from reaching the built-in power supply 19 and causing the temperature of the built-in power supply 19 to rise too high, which is beneficial to extending the service life of the built-in power supply 19. The heat insulator is, for example, a partition plate provided between the built-in power supply 19 and the heating element 14, or the heat insulator is a heat shield covering the outside of the built-in power supply 19, etc., which can be set according to actual needs.
[0061] As a preferred embodiment, the operating voltage of the built-in power supply 19 does not exceed 36V. Using a relatively small operating voltage in the heat preservation stage can prevent accidents such as electric leakage and electric shock, and improve the use safety.
[0062] It can be understood that when the fryer assembly 11 is used in the assembly cavity 10, the voltage output by the household power supply is common AC mains such as 110V and 220V.
[0063] As a preferred embodiment, the fryer assembly 11 includes a cover body 22 provided below the pot body 12. The cover body 22 has an opening at the top. The cover body 22 and the bottom wall of the pot body 12 enclose a heat preservation cavity 13. The top edge of the cover body 22 is provided with an outwardly extending flanging 221, and the flanging 221 is fixedly connected to the bottom wall of the pot body 12.
[0064] As Figure 3 shown, by using the flanging 221 to fit the bottom wall of the pot body 12, it can prevent heat loss caused by gaps between the cover body 22 and the pot body 12, and can ensure the heating efficiency of the heating element 14 for the food materials. Specifically, the flanging 221 and the bottom wall of the pot body 12 can be connected into one body by means such as screw fixation, rivet fixation, and welding.
[0065] As a preferred embodiment, the bottom wall of the heat preservation cavity 13 is provided with an upwardly concave mounting opening 23, the first coupler 15 is arranged in the mounting opening 23, and a seal 24 is provided between the first coupler 15 and the mounting opening 23.
[0066] As Figure 3 shown, by setting the seal 24 at the installation position of the first coupler 15, it can prevent water on the tabletop where the pot body 12 is placed or water during the cleaning process of the pot body 12 from entering the heat preservation cavity 13 through the installation opening 23 and damaging the electronic devices in the heat preservation cavity 13, and can improve the overall use performance and service life of the fryer assembly 11.
[0067] As a preferred embodiment, the bottom wall of the heat preservation cavity 13 is provided with a support rib 25. In the second state, the fryer assembly 11 is placed on the tabletop through the support rib 25.
[0068] The heat insulation cavity 13 and the tabletop are isolated by the support ribs 25, which can prevent the tabletop from being burned by high temperature. The support ribs 25 are made of high-temperature resistant materials. The support ribs 25 can be annular support ribs 25, or the support ribs 25 can include a plurality of strip-shaped rib strips or the support ribs 25 can include a plurality of bump-shaped ribs, which are spaced apart and distributed on the bottom wall of the heat insulation cavity 13.
[0069] It can be understood that, as Figure 1 shown, when the fryer assembly 11 is placed in the assembly cavity 10 for use, the bottom wall of the heat insulation cavity 13 is higher than the bottom wall of the assembly cavity 10. In the embodiment provided with the support ribs 25, the support ribs 25 preferably can abut against the bottom wall of the assembly cavity 10, so that the stability of the support of the fryer assembly 11 can be enhanced, and the fryer assembly 11 can be prevented from being placed unstably and affecting the insertion effect of the first coupler 15 and the second coupler 16.
[0070] The technical solution protected by the present utility model is not limited to the above embodiments. It should be pointed out that the combination of the technical solution of any one embodiment and the technical solutions of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail with general descriptions and specific embodiments above, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all belong to the scope required to be protected by the present utility model.
