Description

Technical Field

[0001] The utility model relates to the field of kitchen appliances, in particular to an air fryer. Background Art

[0002] An air fryer is a cooking appliance that uses hot air to bake food. In actual use, existing air fryers lose moisture from the food as it is carried away by the hot air, resulting in a dry, tough texture and a poor cooking experience. To address this problem, existing techniques typically use a steam generator to deliver steam to the cooking chamber, increasing the humidity in the cooking chamber to slow moisture loss and improve the food's texture.

[0003] Currently, there are generally two types of steam generators used in air fryers. One type heats water in an instant heating module and vaporizes it into steam. The steam is then fed into the cooking chamber through small pipes to heat the ingredients. Ordinary water sources, after being heated and vaporized, retain a lot of scale, which can easily clog the small pipes, making them difficult to clean and affecting the safety of the product. To ensure product reliability, these steam generators generally have high water source requirements and require the use of purified water, which leads to certain limitations in this solution. Another type of boiler-type steam generator, however, is a type that heats and vaporizes water by introducing it into a boiler. When using ordinary water, although most of the scale will remain in the boiler, the scale carried by the steam during the boiling process can easily accumulate at the boiler's steam outlet, still posing a risk of clogging and making cleaning difficult. Similarly, to ensure product reliability, the use of purified water is generally recommended for this type of steam generator.

[0004] For example, Chinese patent CN202120696060.7 discloses an air fryer with a steam generator. The steam generator is located at the bottom of the base, and steam generated by the steam generator is transported from the top of the cooking chamber into the cooking chamber via a steam outlet pipe. This solution generates a large amount of scale in the steam generator. However, some of the scale remaining in the steam will remain at the entrance of the steam outlet pipe as the steam is discharged. This poses a risk of clogging the steam outlet pipe during long-term use, as it is difficult to clean. Utility Model Content

[0005] The utility model provides an air fryer, which aims to solve the problem that the existing steam generator is prone to scale generation and is difficult to clean when using ordinary water source for heating and vaporization, resulting in poor exhaust.

[0006] The utility model discloses an air fryer, comprising a cooking cavity and a steam generator for conveying steam to the cooking cavity, the steam generator comprising a heating element and a water container, the water container comprising a box body with an upper opening and a detachable cover provided above the box body, the cover body and the box body enclose a steam generating cavity, the heating element heats a water source in the box body to generate steam in the steam generating cavity, and after the cover body and the box body are assembled, the cover body cooperates with the box body to separate a steam pipe in the steam generating cavity to discharge steam.

[0007] The air fryer of the present invention also has the following additional technical features:

[0008] The heating element is attached to the outer wall of the box body, and the cover body includes a top plate and a surrounding plate extending from the top plate into the steam generating chamber, and the surrounding plate and the side wall of the box body form the steam pipe.

[0009] The enclosure includes a first enclosure extending vertically and a flange portion extending radially outward from the bottom end of the first enclosure. The top plate, the first enclosure, the flange portion and the side wall of the box body form the steam pipe.

[0010] A backflow gap is provided between the flange portion and the side wall of the box body.

[0011] The enclosure includes a first enclosure extending vertically, the bottom end of the first enclosure extends into the water source, and the top plate, the first enclosure, the water source and the side wall of the box body form the steam pipe.

[0012] The enclosure includes a first enclosure extending vertically, a transverse plate is provided on the side wall of the box body, and the transverse plate extends into the steam generating chamber. The top plate, the first enclosure, the transverse plate and the side wall of the box body form the steam pipe.

[0013] The steam inlet of the steam pipe is arranged on the first enclosure plate, and / or the steam outlet of the steam pipe is arranged on the side wall of the box body.

[0014] The steam inlet and the steam outlet of the steam pipe are arranged at intervals, and the angle formed by the line connecting the steam inlet to the central axis of the box body and the line connecting the steam outlet to the central axis of the box body is in the range of 90° to 180°.

[0015] The box body is provided with a water inlet communicated with the steam generating chamber, and the bottom wall of the box body is arranged to be inclined downward from the water inlet in a direction away from the water inlet.

[0016] The box body is provided with a water inlet communicated with the steam generating chamber, the heating element has a cold end and a hot end, and the cold end is arranged close to the water inlet relative to the hot end.

[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0018] 1. Existing steam generators are difficult to clean when using ordinary water sources for cooking. During long-term use, scale can easily clog the exhaust pipe, affecting the steam exhaust rate of the steam generator, resulting in slow steam generation. This is not conducive to timely rehydration of ingredients and affects the taste of the ingredients. To address this problem, the present application provides a steam generator that utilizes a water container box and a cover to separate a steam pipe within a steam generating chamber. Steam within the steam generating chamber is discharged through the steam pipe, and scale carried by the steam during discharge remains in the steam pipe, greatly reducing the scale content in the steam discharged by the steam generator. Furthermore, because the cover and box of the water container are detachable, the steam pipe structure disappears after the cover is removed, making it easy to clean the interior of the box and cover. During this process, the parts of the box and cover that form the steam pipe are also cleaned, and scale can be promptly removed. During subsequent use, the problem of poor exhaust due to scale blockage will not occur. Moreover, due to its easy cleaning, it can be used regardless of the water source, reducing the user's requirements for water quality. Furthermore, the steam pipe of the present application is formed by the assembled cover body and the water container, and does not require the provision of additional components, thereby simplifying the overall structure of the steam generator and improving the convenience of cleaning.

[0019] 2. In a preferred embodiment of the present application, the heating element is attached to the outer wall of the box body. The box body has a bottom wall and side walls extending upward from the periphery of the bottom wall. The cover body includes a top plate and a panel extending from the top plate into the steam generating chamber. The panel and the side walls of the box body cooperate to form the steam pipe. By attaching the heating element to the outer wall of the box body, the temperature of the side walls of the box body is higher after the heating element heats the box body. As the side walls of the box body serve as part of the steam pipe, the steam entering the steam pipe is secondary heated by the side walls of the box body during the process of steam passing through the steam pipe, thereby increasing the temperature of the steam and preventing steam liquefaction. It can also heat and vaporize water droplets that have not been completely vaporized in the steam, thereby increasing steam output.

[0020] As a preferred embodiment of this embodiment, the enclosure includes a first enclosure and a flange extending radially outward from the bottom end of the first enclosure. The top plate, the first enclosure, the flange, and the sidewalls of the box body together form the steam conduit. In this embodiment, the flange forms the bottom wall of the steam conduit. The flange helps vertically separate the steam conduit from the water source within the steam generation chamber, reducing the likelihood of water entering the steam conduit, improving the purity of the steam within the steam conduit, and preventing excessive water droplets from being included in the steam that acts on the food.

[0021] As a preferred embodiment of this embodiment, the bottom end of the first enclosure extends into the water source within the box body, and the top plate, the first enclosure, the water source, and the side walls of the box body together form the steam conduit. This embodiment simplifies the structure of the lid and utilizes the water source as the bottom wall of the steam conduit, enriching the ways in which the steam conduit can be formed.

[0022] 3. Under the premise that secondary heating can be obtained in the steam pipeline, in order to fully heat the steam in the steam pipeline, so that the water droplets that are not completely vaporized can be heated and vaporized, thereby increasing the steam output and avoiding the situation where the steam is not heated in time, the positional relationship between the steam inlet and the steam outlet can be optimized.

[0023] In a preferred embodiment, the steam conduit is provided with a steam inlet and a steam outlet spaced apart from each other, with the angle formed between a line connecting the steam inlet and the central axis of the casing and a line connecting the steam outlet and the central axis of the casing being in the range of 90° to 180°. By providing a certain distance between the steam inlet and the steam outlet, the steam can be sufficiently reheated as it flows from the steam inlet to the steam outlet, thereby improving the purity of the steam output from the steam outlet.

[0024] 4. When the bottom wall of the box is set horizontally, due to the effect of fluid viscosity, when the water volume is small, water tends to accumulate at the water inlet, causing dry burning at other positions, so that only the water inlet position can be effectively heated, thereby reducing the heating efficiency.

[0025] In a preferred embodiment, the box body is provided with a water inlet communicating with the steam generation chamber, and the bottom wall of the box body is arranged to be inclined downward from the water inlet in a direction away from the water inlet. By slanting the bottom wall of the box body, even if only a small amount of water enters, the water will flow from the water inlet to the far end and be heated throughout the flow process, thereby improving heating efficiency.

[0026] When the bottom wall of the box body is tilted, more water tends to accumulate on the side away from the water inlet. To further improve heating efficiency, as a preferred embodiment of this embodiment, the heating element is disposed at the bottom of the box body. The heating element includes a cold end and a hot end, with the cold end being disposed closer to the water inlet than the hot end. That is, the hot end is disposed at a location where more water accumulates, allowing the water to be fully and quickly heated, thereby improving heating efficiency.

[0027] 5. When steam enters the steam pipe from the steam generating chamber, some of it condenses upon contact with the relatively cool chamber walls, forming condensed water. To improve the purity of the steam within the steam pipe and prevent water droplets from being mixed with the steam and discharged, a preferred embodiment includes a reflux gap between the flange and the sidewall of the box body, connecting the steam pipe with the water source within the steam generating chamber. This reflux gap allows the generated condensed water to flow back into the steam generating chamber and be reheated, preventing steam mixed with excessive water droplets from causing the food to become overly soggy and affect its taste.

[0028] 6. When the steam generator of the above embodiment is applied to the air fryer of the present application, the steam generator can provide steam to the cooking cavity, which can improve the taste of food and prevent the food from becoming dry and tough; the steam generator is arranged on the top of the body, which makes it convenient for the user to remove the cover to add water to the box body and clean the inside of the box body and the cover body, thereby improving the operational convenience.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features.

[0047] like Figures 1 to 6 As shown, the present application provides a steam generator 10, including a heating element 11 and a water storing element 12. The water storing element 12 includes a box body 14 with an upper opening and a detachable cover 13 provided above the box body 14. A water source 15 is contained in the box body 14. The cover 13 and the box body 14 enclose a steam generating chamber 16. The heating element 11 heats the water source 15 to generate steam in the steam generating chamber 16. After the cover 13 and the box body 14 are assembled, the cover 13 and the box body 14 cooperate to separate a steam pipe 17 for discharging steam in the steam generating chamber 16.

[0048] When using ordinary water sources for cooking, existing steam generators are difficult to clean. During long-term use, scale easily clogs the exhaust pipe, which in turn affects the steam exhaust rate of the steam generator, resulting in slow steam generation, which is not conducive to timely hydration of food ingredients and affects the taste of the food ingredients. To solve this problem, the present application provides a steam generator 10. The scale carried by the steam during discharge through the steam pipe 17 remains in the steam pipe 17. The residual scale in the steam discharged by the steam generator 10 is greatly reduced. Moreover, a detachable cover 13 is used. By removing the cover 13, it is easy to clean the inside of the box body 14 and the cover 13, which is equivalent to cleaning the steam pipe 17. By promptly removing the scale remaining in the steam pipe 17, the ventilation performance of the steam generator 10 can be guaranteed. Smooth exhaust is conducive to the timely action of steam on food ingredients, improving the taste of food ingredients. Because of the easy cleaning, it can be achieved without being picky about water sources, reducing the user's requirements for water quality.

[0049] Furthermore, in order not to increase the complexity of the structure and improve the convenience of cleaning, the steam pipe 17 of the present application is formed by the assembled cover body 13 and the box body 14, and no additional components are required, which simplifies the overall composition configuration of the steam generator 10.

[0050] like Figures 1 to 4 As shown, the cover 13 and the box body 14 are used to enclose a steam generating chamber 16, and the cover 13 and the box body 14 separate a steam pipe 17 within the steam generator 16. This means that no additional structure is required besides the cover 13 and the box body 14, making the overall structure of the steam generator 10 simple. Moreover, the cover 13 can be installed and the steam generating chamber 16 and the steam pipe 17 can be formed in one action by covering the cover 13. This reduces the number of operating steps, greatly saving user operation and improving the user experience. The steam generator 10 can be used in appliances such as air fryers, ovens, and rice cookers. The steam generator 10 can be a structure that can be completely removed from the cooking appliance so that the entire structure can be removed and cleaned to improve the cleaning effect, or the box body 14 can be fixed to the cooking appliance, and the user only needs to remove the cover 13 to clean the box body 14. The water source 15 in the box body 14 can be tap water, purified water, etc., without any requirements.

[0051] To prevent steam from liquefying within the steam pipe 17, as a preferred embodiment, the heating element 11 is attached to the outer wall of the box body 14. The lid 13 includes a top plate 131 and a panel extending from the top plate 131 into the steam generating chamber 16. The panel and the side walls 141 of the box body form a steam pipe 17. This allows the steam entering the steam pipe 17 to be reheated, raising the steam temperature and heating and vaporizing any incompletely vaporized water droplets in the steam, thereby increasing steam output. It is understood that the heating element 11 can be attached to the side wall or the bottom wall of the box body 14. Furthermore, in other embodiments, the heating element 11 can also extend into the steam generating chamber 16.

[0052] In a preferred embodiment, the heating element 11 is attached to the outer wall of the box body 14. The box body 14 has a bottom wall and side walls extending upward from the periphery of the bottom wall. The lid 13 includes a top plate 131 and a first enclosure 132 extending vertically from the top plate 131 into the steam generation chamber 16. The first enclosure 132 cooperates with the side walls of the box body to form a steam conduit 17. By attaching the heating element 11 to the box body 14, the temperature of the side walls 141 of the box body is higher after the heating element 11 heats the box body 14. As part of the steam conduit 17, the side walls 141 of the box body can reheat the steam entering the steam conduit 17, thereby improving heat utilization.

[0053] like Figure 2 and Figure 3 As shown, in this embodiment, the steam pipe 17 surrounds the circumference of the side wall of the box body, so that the heat of the side wall of the box body can fully heat the steam in the steam pipe 17 for secondary heating.

[0054] As a preferred embodiment of this embodiment, Figure 2 As shown, the enclosure includes a first enclosure 132 and a flange 133 extending radially outward from the bottom end of the first enclosure 132. The top plate 131, the first enclosure 132, the flange 133, and the sidewalls 141 of the box body together form the steam conduit 17. In this embodiment, the flange 133 forms the bottom wall of the steam conduit 17. The flange 133 helps vertically separate the steam conduit 17 from the water source within the steam generating chamber 16, thereby reducing the probability of water entering the steam conduit 17, improving the purity of the steam within the steam conduit 17, and preventing excessive water droplets from being mixed into the steam that acts on the food.

[0055] In this embodiment, in order to achieve communication between the steam pipe 17 and other areas of the steam generating chamber 16 , the steam pipe 17 is provided with a steam inlet 18 , which can be provided on the first enclosure 132 or the flange portion 133 .

[0056] When steam enters the steam pipe 17 from other areas of the steam generating chamber 16 (except the steam pipe 16), a portion of the steam will condense to form condensed water when it contacts the chamber wall with a relatively low temperature. In order to improve the purity of the steam in the steam pipe 17 and prevent some water droplets from being mixed in the steam and output, a reflux gap 134 is further provided between the flange portion 133 and the side wall 141 of the box body to connect the steam pipe 17 and the water source in the steam generating chamber 16. By providing the reflux gap 134, the generated condensed water can flow back to the water source 15 in the steam generating chamber 16 through the reflux gap 134 and be heated again, which can prevent the steam mixed with too many water droplets from being output to the food, causing the food to be too wet and soft and affecting the taste. The reflux gap 134 is, for example, 1mm-2mm to avoid steam loss caused by a gap that is too large.

[0057] As a preferred embodiment of this embodiment, Figure 3 As shown, the bottom end of the first enclosure 132 extends into the water source 15, and the top plate 131, the first enclosure 132, the water source 15, and the side walls 141 of the box body together form the steam conduit 17. This embodiment simplifies the structure of the lid 13 and utilizes the water source 15 as the bottom wall of the steam conduit 17, enriching the ways in which the steam conduit 17 can be formed.

[0058] In this embodiment, in order to achieve communication between other areas of the steam generating chamber 16 and the steam pipe 17 , the steam pipe 17 is provided with a steam inlet 18 , which may be provided on the first enclosure 132 .

[0059] As a preferred embodiment, the enclosure includes a first enclosure 132 extending vertically, and a horizontal plate extending into the steam generating chamber 16 is provided on the side wall 141 of the box body. The top plate 131, the first enclosure 132, the horizontal plate, and the side wall 141 of the box body together form a steam pipe 17.

[0060] It is understood that the steam pipe 17 formed by the box body 14 and the cover 13 can be a steam pipe 17 directly enclosed by the cover 13 and the box body 14, or a steam pipe 17 formed by the cover 13 and the water source in the box body 14. In the present application, the steam pipe 17 formed by the cover 13 and the box body 14 does not exist when the box body 14 and the cover 13 are separated, that is, the cover 14 and the box body 13 do not have a complete steam pipe 17. The steam pipe 17 is only formed when the cover 14 and the box body 13 are closed.

[0061] As a preferred embodiment, the cover body 13 includes a top plate 131 and a second enclosure 135 and a third enclosure 136 extending from the top plate 131 into the steam generating chamber 16 and radially spaced apart. The second enclosure 135 and the third enclosure 136 both extend into the water source 15. The top plate 131, the second enclosure 135, the third enclosure 136 and the water source 15 together form a steam pipe 17.

[0062] In order to fully heat the steam in the steam pipe 17, vaporize the water droplets that have not been completely vaporized, thereby increasing the steam output and avoiding the situation where the steam is not heated in time, the positional relationship between the steam inlet 18 and the steam outlet 19 can be optimized.

[0063] As a preferred embodiment, the steam conduit 17 is provided with a steam inlet 18 and a steam outlet 19 spaced apart from each other. The angle formed between the line connecting the steam inlet 18 and the central axis of the casing 14 and the line connecting the steam outlet 19 and the central axis of the casing 14 is in the range of 90° to 180°. By providing a certain distance between the steam inlet 18 and the steam outlet 19, the steam can be fully reheated during its flow from the steam inlet 18 to the steam outlet 19, thereby improving the purity of the steam output from the steam outlet 19.

[0064] like Figure 5 As shown, in one embodiment, the steam inlet 18 and the steam outlet 19 are arranged relative to each other, that is, the angle formed between the line connecting the steam inlet 18 and the central axis of the box body 14 and the line connecting the steam outlet 19 and the central axis of the box body 14 is 180°. This can maximize the travel between the steam inlet 18 and the steam outlet 19 to ensure that the steam is fully heated during the flow process. The steam outlet 19 can be located on the side wall of the box body, and the steam inlet 18 can be located on the first panel.

[0065] When the bottom wall of the box body 14 is set horizontally, due to the effect of fluid viscosity, when the water volume is small, water tends to accumulate at the water inlet 20, causing dry burning at other positions, so that only the water inlet 20 can be effectively heated, thereby reducing the heating efficiency.

[0066] As a preferred embodiment, the box body 14 is provided with a water inlet 20 communicating with the steam generating chamber 16, and the bottom wall of the box body 14 is inclined downward from the water inlet 20 to a direction away from the water inlet 20. Figure 2 As shown, by tilting the bottom wall of the box body 14, even if only a small amount of water enters, the water will flow from the water inlet 20 to the far end and be heated throughout the flow process, thereby improving the heating efficiency.

[0067] When the bottom wall of the box body 14 is tilted, more water is likely to accumulate on the side away from the water inlet 20. In order to further improve the heating efficiency, Figure 6 As shown in FIG. 1 , as a preferred embodiment of this embodiment, a heating element 11 is disposed at the bottom of the housing 14. The heating element 11 includes a cold end 111 and a hot end 112. The cold end 111 is positioned closer to the water inlet 20 than the hot end 112. In other words, the hot end 112 is positioned where water accumulates more, allowing the water to be heated quickly and efficiently, thereby improving heating efficiency. The heating element 11 is, for example, a heat pipe, which can be configured in a C-shaped, U-shaped, or reciprocatingly bent shape.

[0068] When the steam generator 10 of the above-mentioned embodiment is applied to the air fryer 21 of the present application, the steam generator 10 can provide steam to the cooking cavity, which can improve the taste of food and prevent the food from becoming dry and tough; the steam generator 10 is arranged on the top of the body, which is convenient for the user to remove the cover 13 to add water to the box body 14 and clean the inside of the box body 14 and the cover 13, thereby improving the operating convenience.

[0069] like Figure 7 As shown, the present application provides an air fryer 21, comprising a body and a cooking cavity arranged in the body, a concave mounting cavity 22 is provided on the top of the body, and a steam generator 10 as described in the above embodiment is provided in the mounting cavity 22, and the steam generator 10 is used to provide steam to the cooking cavity.

[0070] like Figure 8 As shown, the top of the cover 13 of the steam generator 10 is exposed, and a handle 137 is provided on the upper surface of the cover 13. The user can remove the cover 13 through the handle 137 to add water, which is convenient to use. A steam delivery pipeline is provided between the steam generator 10 and the cooking cavity. When the air fryer 21 is working, steam is delivered to the cooking cavity through the steam generator 10. The steam can heat the food in the cooking cavity and improve the taste of the food. The user can remove the cover 13 at any time to add water, ensuring the steam production. The air fryer 21 can be a flip-top air fryer 21 or a drawer-type air fryer 21, and this application does not limit it.

[0071] The technical solutions protected by this utility model are not limited to the above-described embodiments.
