Description

Technical Field

[0001] The utility model relates to the field of air fryers, in particular to a visible air fryer with safe use. Background Art

[0002] With the improvement of people's living standards, the utilization rate of air fryers is getting higher and higher. Among the existing air fryers, most of them do not have a visible function, resulting in poor user experience during use. To meet the needs of users, a type of air fryer with a visible function has emerged on the market. This type of air fryer is provided with a viewing window communicating with the cooking cavity on the body. Through the viewing window, users can directly observe the cooking state of the food in the cooking cavity, so as to cook better. However, since the viewing window is directly connected to the cooking cavity and in direct contact with the circulating heat flow in the cooking cavity, the high temperature in the cooking cavity is easily transferred to the surface of the viewing window, causing scalding to users and poor user safety. Summary of the Utility Model

[0003] This application provides a visible air fryer with safe use to solve the technical problems that the existing air fryers cannot be visible and have poor use safety.

[0004] To solve the above technical problems, the utility model provides a visible air fryer with safe use, which includes a body, a cooking cavity arranged in the body, and a hot air circulation system communicating with the cooking cavity. The top of the cooking cavity is provided with a top opening, and a window assembly for closing the top opening is arranged at the top opening. The window assembly includes a first transparent plate arranged at the top of the cooking cavity to close the top opening, a third transparent plate arranged on the upper surface of the body, and a second transparent plate spaced between the first transparent plate and the third transparent plate. A first heat insulation cavity is adapted to be formed between the first transparent plate and the second transparent plate, and a second heat insulation cavity is adapted to be formed between the second transparent plate and the third transparent plate. By arranging the top opening at the top of the cooking cavity and arranging the window assembly for closing the top opening at the top opening, the air fryer can not only make the situation in the cooking cavity visible, effectively improving the user's cooking experience, but also enable users to cook food better, effectively improving the cooking effect. At the same time, by setting the window assembly as a three-layer transparent plate structure and forming a heat insulation cavity between the transparent plates and the adjacent transparent plates, good heat insulation can be achieved, effectively reducing the risk of the high temperature in the cooking cavity being transferred outward and scalding users, and improving the user's use safety.

[0005] In an alternative embodiment, an air duct plate is provided at the top of the cooking cavity, and the top opening is provided on the air duct plate. An upper cooking mechanism is provided above the air duct plate, and a perforation corresponding to the top opening is provided on the upper cooking mechanism. The second transparent plate is provided on the upper cooking mechanism and closes the perforation. An annular separator is provided between the top opening and the perforation. The first transparent plate and the second transparent plate are respectively clamped between the air duct plate and the upper cooking mechanism and the annular separator. By providing the annular separator between the air duct plate and the upper cooking mechanism, not only can the installation and fixation of the first transparent plate and the second transparent plate be realized, but also the first transparent plate and the second transparent plate can be separated to form the first heat insulation cavity, so as to insulate the high temperature in the cooking cavity, reduce the risk of the high temperature in the cooking cavity being transmitted outward and scalding the user, and effectively improve the use safety of the air fryer.

[0006] In an alternative embodiment, a sealing sleeve made of an elastic high-temperature resistant material is sleeved on the periphery of the first transparent plate. The first transparent plate is adapted to abut against the annular separator and the air duct plate through the sealing sleeve. The sealing sleeve is adapted to play a sealing role. Through the sealing sleeve, the sealing connection between the first transparent plate and the annular separator and the air duct plate can be realized, which can not only effectively prevent the high-temperature heat flow in the cooking cavity from flowing out to the outside of the cooking cavity, thus causing damage to the electrical components outside the cooking cavity, but also effectively reduce the transmission of the high temperature in the cooking cavity outward, resulting in the surface temperature of the body and / or the window assembly being too high, thus scalding the user. The performance stability and use safety of the air fryer are effectively improved.

[0007] In an alternative embodiment, a third heat insulation cavity is adapted to be formed between the air duct plate, the upper cooking mechanism and the annular separator, and a heat insulation layer is provided in the third heat insulation cavity. By providing the third heat insulation cavity between the air duct plate, the upper cooking mechanism and the annular separator and providing the heat insulation layer in the third heat insulation cavity, the body around the window assembly can be insulated to reduce the risk that the surface temperature of the body around the window assembly is too high caused by the transmission of the high temperature in the cooking cavity outward, thus scalding the user, and the use safety of the air fryer is effectively improved.

[0008] In an alternative embodiment, a heat dissipation air duct communicating with the atmosphere is provided inside the machine body. A heat dissipation component for generating a heat dissipation cold flow is provided in the heat dissipation air duct. The heat dissipation air duct is adapted to surround at least part of the third heat insulation cavity. By providing the heat dissipation air duct inside the machine body and surrounding at least part of the third heat insulation cavity with the heat dissipation air duct, it is possible to use the heat dissipation cold flow in the heat dissipation air duct to dissipate heat from the third heat insulation cavity, so as to reduce the risk that the high temperature in the cooking cavity is transferred outward through the third heat insulation cavity, resulting in too high a surface temperature of the machine body and scalding the user, effectively improving the use safety of the air fryer.

[0009] In an alternative embodiment, a heat dissipation air duct communicating with the atmosphere is provided inside the machine body. A heat dissipation component for generating a heat dissipation cold flow is provided in the heat dissipation air duct. The heat dissipation air duct is adapted to communicate with the second heat insulation cavity. By providing the heat dissipation air duct inside the machine body and communicating the heat dissipation air duct with the second heat insulation cavity, it is possible to use the heat dissipation cold flow in the heat dissipation air duct to dissipate heat from the second heat insulation cavity, so as to reduce the risk that the high temperature in the cooking cavity is transferred outward through the second heat insulation cavity, resulting in too high a surface temperature of the window assembly and scalding the user, effectively improving the use safety of the air fryer.

[0010] In an alternative embodiment, an installation cavity is provided outside the second heat insulation cavity. Electrical components are provided in the installation cavity. An insulation board separating the second heat insulation cavity and the installation cavity is provided between the second heat insulation cavity and the installation cavity. A fourth heat insulation cavity is adapted to be formed between the insulation board and the outer wall of the installation cavity. By providing the fourth heat insulation cavity between the second heat insulation cavity and the installation cavity, it is not only possible to reduce the probability that the high temperature in the cooking cavity is transferred to the installation cavity and damage the electrical components in the installation cavity, but also to prevent the heat dissipation cold flow with heat in the second heat insulation cavity from blowing into the installation cavity, resulting in too high a temperature in the installation cavity and affecting the normal operation of the electrical components in the installation cavity, effectively improving the performance stability and use safety of the air fryer.

[0011] In an alternative embodiment, the insulation board is adapted to be made of an insulating material. By using an insulating material to make the insulation board, the heat insulation effect of the fourth heat insulation cavity can be further improved, effectively reducing the influence of the high temperature heat transfer in the cooking cavity on the electrical components in the installation cavity, ensuring the normal operation of the electrical components in the installation cavity, and effectively improving the performance stability of the air fryer.

[0012] In an alternative embodiment, the first transparent plate is adapted to be made of a high temperature resistant transparent material. By using a high temperature resistant transparent material to make the first transparent plate, the influence of the high temperature in the cooking cavity on the performance of the first transparent plate can be avoided, ensuring the performance stability and structural reliability of the first transparent plate.

[0013] In an optional embodiment, an installation groove is provided around the top opening of the body, the third perspective plate is disposed in the installation groove, and the top of the third perspective plate is flush with the top plane of the installation groove. By disposing the third perspective plate in the installation groove and making it flush with the top plane of the installation groove, the third perspective plate can be hidden, thereby enhancing the overall aesthetic appearance of the air fryer.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] By providing the top opening at the top of the cooking cavity and providing the window assembly for closing the top opening at the top opening, the present application can not only make the situation inside the cooking cavity visible, effectively improving the user's cooking experience, but also enable the user to cook food better, effectively improving the cooking effect. At the same time, by setting the window assembly as a three-layer perspective plate structure and forming a heat insulation cavity between adjacent perspective plates, good heat insulation can be achieved, effectively reducing the risk of the high temperature inside the cooking cavity being transmitted outward and scalding the user, thereby enhancing the user's safety in use.

The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description can be applied to other embodiments, variations, improvements, equivalent embodiments, and other technical solutions that do not depart from the spirit and scope of the present utility model.

[0020] It should be noted that the terms used here are only for describing the specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship. Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods and devices should be regarded as part of the authorization specification. In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it will not be further discussed in subsequent drawings.

[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0023] And for the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" and the like can be used here to describe the spatial positional relationship of one device or feature to other devices or features as shown in the drawings. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made to the spatial relative descriptions used here.

The term "one" should not be understood as a limitation on the quantity. The use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above terms have no special meaning and thus should not be understood as a limitation on the protection scope of the present utility model.

The first perspective plate 31 and the second perspective plate 32 are adapted to be respectively clamped between the duct plate 12 and the upper machine core 13 and the annular separator 50. By providing the annular separator 50 between the duct plate 12 and the upper machine core 13, not only can the installation and fixation of the first perspective plate 31 and the second perspective plate 32 be realized, but also the separation of the first perspective plate 31 and the second perspective plate 32 can be realized to form the first heat insulation cavity 34, so as to insulate the high temperature in the cooking cavity 11, reduce the risk of the high temperature in the cooking cavity 11 being transmitted outward and scalding the user, and effectively improve the use safety of the air fryer.
