Description

Technical Field

[0001] The present application relates to the field of household appliances, and more particularly, to an air fryer. Background Art

[0002] In related solutions, an air fryer with steam is proposed. In this air fryer, steam is added to the fryer to improve the problem that the food cooked by the air fryer is relatively dry. However, different foods have different steam requirements, and the taste of the food cooked with different steam amounts is also completely different. The existing air fryers cannot adjust the steam amount according to actual needs, resulting in poor taste of the cooked food and thus reducing the user experience of using the air fryer.

[0003] Therefore, how to provide an air fryer that can adjust the steam amount has become an urgent problem to be solved at present. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, an object of the present invention is to provide an air fryer.

[0006] To achieve the above object, a technical solution of the first aspect of the present invention provides an air fryer, comprising: a housing; a partition plate installed in the housing and separating the space in the housing into a first cavity and a second cavity that are independently arranged, the partition plate being provided with a steam inlet; a cooking cavity located in the second cavity and communicating with the steam inlet; a hot air module for delivering hot air to the cooking cavity; a steam valve including a steam passage and a movable adjusting member, the steam passage communicating with the steam inlet, the steam passage including a first opening, and the adjusting member being capable of adjusting the cross-sectional area of the steam passage or the opening size of the first opening.

[0007] The air fryer provided by the present invention includes a cooking cavity, a hot air module, and a steam valve. Among them, the food to be cooked can be placed in the cooking cavity for heating and baking. The hot air module is used to generate hot air and circulate the hot air into the cooking cavity. The steam valve can discharge the steam in the cooking cavity. During cooking, the amount of steam to be supplemented can be determined according to the type of food being cooked, and then the cross-sectional area of the steam channel or the opening size of the first opening can be comprehensively determined based on the amount of steam to be supplemented and the amount of steam that can be generated, so as to control the amount of steam that the steam valve can discharge. For example, when cooking a certain kind of food and finding that the cooked food is relatively dry, the steam valve can be closed to prevent the steam from being discharged, so that the food can be hydrated by the steam. On the contrary, if it is found that the cooked food is relatively moist and not crispy, then when cooking this kind of food next time, the steam valve can be fully or partially opened to increase the amount of steam discharged during the cooking process. In addition, a first driving member can also be provided for the adjusting member. At this time, the opening state of the steam valve can be automatically adjusted according to the food being cooked, so as to realize the automatic adjustment of the amount of steam.

[0008] Further, the internal space of the housing is divided into two parts by a partition, namely a first cavity and a second cavity. Among them, the cooking cavity, the hot air module, etc. are installed in the second cavity, and this part of the space is mainly used for heating food. The first cavity is mainly used for placing electrical control components, such as the driving device of the hot air blower, the electronic control board, etc. And a steam inlet is provided on the partition, that is, the steam in the cooking cavity can enter the steam valve through the partition. With this setting, since the steam channel of the steam valve is directly connected to the steam inlet, the steam valve has an independent channel to connect to the cooking area to discharge the steam in the cooking cavity, thereby achieving a complete isolation of the steam channel from the heat dissipation channel, and thus solving the problem of the safety hazard that steam will enter the heat dissipation channel (i.e., the cold air duct), causing the heat dissipation channel to become hot and the heat dissipation function to decline, resulting in overheating of electrical components.

[0009] Optionally, the partition includes: a reflector cover located on the side of the hot air module away from the cooking cavity, and the steam inlet is provided on the reflector cover.

[0010] In this technical solution, the reflector cover is generally arranged above the hot air module and is used to guide the hot air generated by the hot air module towards the cooking cavity. And the steam inlet is generally provided on the reflector cover.

[0011] Further, a sealing member is provided between the partition and the steam valve, and this sealing member can make a sealed connection between the partition and the steam valve, so as to ensure that the steam will not leak into the first cavity.

[0012] Optionally, one end of the steam channel away from the cooking cavity is communicated to the outside. That is, the steam valve can directly discharge the steam from the cooking cavity to the outside of the device, so as to realize the adjustment of the temperature and humidity in the cooking cavity.

[0013] Optionally, a shielding member is provided at one end of the adjusting member. When the shielding member moves in the first direction, the opening area of the first opening gradually decreases. When the shielding member moves in the second direction, the opening area of the first opening gradually increases; wherein, the first direction and the second direction are opposite to each other.

[0014] In this technical solution, the adjusting member includes a shielding member, that is, a structure for shielding the steam passage. At the same time, the shielding member can move back and forth in the first direction and the second direction so as to be able to adjust the opening area of the first opening. With this kind of setting, by the back-and-forth movement of the adjusting member, the increase or decrease adjustment of the opening size of the first opening can be realized.

[0015] Optionally, the upper end surface of the shielding member fits with the inner side surface of the valve cover, so that the upper end surface of the shielding member can abut against or fit with the lower end surface of the first opening, which can ensure the shielding effect of the shielding member on the first opening, avoid steam leakage from the connection between the two, and thus improve the control accuracy of the steam volume.

[0016] Optionally, an operation switch is provided at one end of the adjusting member away from the first opening in the first direction, and the operation switch can drive the shielding member to move in the first direction or the second direction.

[0017] In this technical solution, the operation switch can push the shielding member to move, thereby realizing the adjustment of the opening size of the first opening. The setting of the operation switch enables the user to manually drive the shielding member, thereby realizing the manual control of the steam volume.

[0018] Optionally, the steam valve further includes a detection member. A trigger position is provided on the adjusting member, and the trigger position is used to trigger the detection member during the movement to prompt the position of the shielding member. Optionally, the air fryer further includes: a control device, connected to the detection member, and capable of controlling the humidity of the cooking cavity of the air fryer according to the detection result of the detection member.

[0019] In this technical solution, the detection member is used to detect the position of the adjusting member, and the opening size of the first opening can be determined according to this position. For example, at least one travel switch can be set on the movement track of the adjusting member, and then the corresponding travel switch can be triggered through the trigger position, so that the position of the adjusting member can be determined by whether the travel switch is triggered. After determining the position of the shielding member, the control device can be used to control the operation of the whole product. For example, controlling the heating power of the product, controlling the generation amount of steam, etc. The control device can also control the steam volume according to the position of the adjusting member. For example, controlling the generation amount of steam or controlling the heating power of the food material, etc., so as to control the humidity in the cooking cavity. Of course, in the case where the adjusting member can be automatically adjusted, it can also be determined whether the adjusting member moves in place according to the position of the adjusting member, so as to control the movement of the adjusting member.

[0020] In addition, the control device can also adjust the cooking program according to whether the detection part is triggered or the degree of triggering, thereby improving the taste of the food.

[0021] Optionally, the triggering position is a first protrusion formed by the shielding part along a direction perpendicular to the first direction and facing away from the first opening, and the top end of the first protrusion has a curved surface or an inclined surface for triggering the detection part.

[0022] In this technical solution, a protrusion can be provided on the shielding part to trigger the detection part, so as to facilitate the smooth cooperation between the protrusion and the detection part. The top surface of the protrusion can be set as a curved surface or an inclined surface to ensure that the protrusion can normally trigger the detection part without interfering with the detection part and getting stuck.

[0023] Optionally, a through hole is provided at the position of the valve seat corresponding to the detection part, and the through hole is used for the detection part to trigger the triggering position. Through the setting of this through hole, the shielding part and the detection part can be in normal contact and thus be triggered, so that the position detection of the shielding part can be simply and conveniently realized.

[0024] Optionally, the steam valve further includes: a valve seat; a valve cover installed on the valve seat, a steam exhaust port is provided on the valve cover, and the steam channel is surrounded by the valve cover and the valve seat and is communicated with the steam exhaust port.

[0025] In this technical solution, the valve seat and the valve cover form the outer shell structure of a steam valve, and a steam channel can be defined by the valve seat and the valve cover to realize the discharge of steam. At the same time, a steam exhaust port is provided on the valve cover, and the steam in the steam channel can be discharged to the outside through the steam exhaust port.

[0026] Optionally, the adjusting part is movably arranged between the valve seat and the valve cover. That is, the adjusting part is installed inside the valve seat and the valve cover, so that the opening size of the first opening can be adjusted from the inside of the valve seat and the valve cover. Of course, in other embodiments, the adjusting part can also be arranged outside the valve cover. For example, when the adjusting part is used to adjust the opening size of the steam exhaust port, the adjusting part can be arranged outside the valve cover.

[0027] Optionally, the first opening includes the steam exhaust port, that is, the adjusting part is arranged corresponding to the steam exhaust port and is used to adjust the opening size of the steam exhaust port.

[0028] Since the steam exhaust port is generally arranged on the outer surface of the device, the arrangement of the adjusting part corresponding to the steam exhaust port can make the adjusting part closer to the outer surface of the device. On the one hand, this is convenient for the user to manually adjust the position of the adjusting part to adjust the opening size of the steam exhaust port. On the other hand, when the product is not in use, the steam exhaust port can be completely closed through the adjusting part to prevent external dust and the like from entering the steam valve.

[0029] Optionally, the adjusting member is movably arranged between the valve seat and the valve cover, and an operating window is arranged on the valve cover, which is a clearance position formed by the valve cover being recessed toward the valve seat; the operating switch is movably installed on the valve cover and / or the valve seat, and is located in the clearance position, and the length of the clearance position along the first direction is greater than or equal to the sum of the length of the operating switch along the first direction and the stroke length of the operating switch along the first direction.

[0030] In this technical solution, the operating switch is movably mounted on the valve cover so that the operating switch can be exposed outside, which is convenient for the user to manually operate the operating switch, thereby realizing manual adjustment of the steam volume. The operating window is a clearance position formed by the valve cover being recessed toward the valve seat, thereby preventing the operating switch from protruding too much from the valve cover. The length of the clearance position along the first direction is greater than or equal to the sum of the length of the operating switch along the first direction and the stroke length of the operating switch along the first direction, ensuring that the operating switch can move normally in the clearance position, thereby realizing the size adjustment of the opening area of the steam channel.

[0031] Optionally, a push button is provided on the upper surface of the operating switch, through which the operating switch can be pushed, thereby simply and conveniently adjusting the opening area of the steam valve.

[0032] Optionally, the push button is a second protrusion formed on the upper surface of the operating switch along a direction perpendicular to the first direction and away from the cooking cavity. The second protrusion provides a force point for the user to push the operating switch, thereby making the operation of the operating switch more convenient.

[0033] Optionally, there is a transition arc between the second protrusion and the operating switch, which can make the transition between the operating switch and the second protrusion smoother, thereby improving the appearance of the entire switch.

[0034] Optionally, a guide member that cooperates with each other is provided between the operating switch and the valve cover, and the guide member includes a guide groove and a guide protrusion that adapt to each other, one of the guide groove and the guide protrusion is provided on the valve cover, and the other of the guide groove and the guide protrusion is provided on the operating switch. By providing the guide member, the operating switch can move more smoothly on the valve cover, and the risk of the operating switch being offset during movement can be avoided, thereby avoiding the risk of the operating switch being stuck, and thus making the operating switch more durable.

[0035] Optionally, the valve seat and the valve cover are detachably connected via a buckle, and the valve cover can be removed from the valve seat for cleaning.

[0036] Optionally, the air fryer further includes: a first driving member connected to the adjusting member and configured to drive the adjusting member to move.

[0037] In this technical solution, the first driving member can drive the adjusting member to move, so that the opening size of the steam valve can be automatically adjusted, without the need for manual adjustment by the user, and thus the steam volume can be controlled more precisely.

[0038] Optionally, the air fryer further includes: a heat dissipation air duct, which is independently arranged from the steam channel.

[0039] In this technical solution, the hot air module includes a hot air fan and a heating device. The heating device is used to heat the gas, and the hot air fan is used to make the gas circulate in the cooking cavity, so that hot air can be generated cyclically. The heat dissipation air duct includes an air inlet and an air outlet, and the heat dissipation fan is used to make the air outside the air inlet enter the heat dissipation air duct, and then after passing through the components that need to be dissipated, it is discharged from the air outlet. Specifically, the second driving member of the hot air fan, the electronic control board, etc. can be installed in the heat dissipation air duct so as to dissipate heat through the heat dissipation air duct. The heat dissipation air duct is independently arranged from the steam channel, which can prevent steam from entering the heat dissipation air duct, thereby avoiding the steam in the cooking cavity from entering the heat dissipation air duct and affecting the heat dissipation effect of the product. Thus, it can solve the problem in the related solutions that steam easily enters the heat dissipation air duct, resulting in a reduction in the heat dissipation effect and easy damage to the parts in the heat dissipation air duct.

[0040] Optionally, the air fryer further includes: the valve seat includes an extension portion. The extension portion is attached to the partition plate, and the steam channel includes a steam inlet channel located in the extension portion, and the steam inlet channel is communicated with the steam inlet. Optionally, a sealing member is arranged between the partition plate and the extension portion for making the partition plate and the extension portion be sealed and connected; the heat dissipation air duct is located in the first cavity.

[0041] In this technical solution, the internal space of the housing is divided into two parts by the partition plate, namely the first cavity and the second cavity. Among them, the cooking cavity, the hot air module, etc. are installed in the second cavity, and this part of the space is mainly used for heating food ingredients. The first cavity is mainly used for placing electrical control components, such as the driving device of the hot air fan, the electronic control board, etc. The partition plate is provided with a steam inlet, that is, the steam in the cooking cavity can enter the steam valve through the partition plate. Specifically, the steam valve includes an extension portion with a steam inlet channel, and the steam valve is attached to the partition plate through the extension portion and is communicated with the cooking cavity through the extension portion. In addition, a sealing member is arranged between the partition plate and the extension portion, and this sealing member can make the partition plate and the extension portion be sealed and connected, so as to ensure that steam will not leak into the first cavity.

[0042] Furthermore, the partition plate and the housing are sealed and connected, that is, the first cavity and the second cavity are disconnected and not communicated with each other, that is, the steam in the cooking cavity cannot enter the first cavity, so that steam can be prevented from entering the heat dissipation air duct and causing the heat dissipation air duct to become hot. In this way, the heat dissipation efficiency of the product can be ensured, and the safety hazard caused by overheating of the electrical components can be avoided.

[0043] Optionally, the partition includes: a reflective cover located on the side of the hot air module away from the cooking cavity, and a steam inlet provided on the reflective cover.

[0044] In this technical solution, the reflective cover is generally provided above the hot air module to direct the hot air generated by the hot air module towards the cooking cavity. And the steam inlet is generally provided on the reflective cover.

[0045] Optionally, the heat dissipation air duct includes an air inlet, the housing includes an upper cover body, the upper cover body includes an upper cover body top cover and an upper cover body side wall, and the air inlet is provided on the upper cover body side wall.

[0046] The upper cover body includes two parts, a top cover and a side wall. One end of the heat dissipation air duct is provided with an air inlet, and one end of the heat dissipation air duct can be extended to the side wall of the upper cover body to facilitate the inflow of air. At the same time, the exhaust port of the steam valve can be provided on the top of the upper cover body, so that the exhaust port and the air inlet are relatively far away from each other, avoiding the discharged steam being sucked into the heat dissipation air duct.

[0047] Optionally, the upper cover body side wall is formed as an inclined wall that slopes downward from top to bottom towards the axis direction of the air fryer, and the air inlet is provided on the inclined wall.

[0048] In this solution, the side wall is inclined, and the inclined direction is inwardly inclined. The upper cover body has a shape that is wider at the top and narrower at the bottom. By providing the air inlet on the inclined wall, on the one hand, it can play a certain guiding role to facilitate the inflow of air, and on the other hand, the wider structure on the upper side can block a part of the naturally falling dust, avoiding dust from entering through the air inlet and affecting the heat dissipation fan, etc.

[0049] Optionally, the heat dissipation air duct includes an air outlet; the air outlet is located on the upper cover body side wall and faces away from the air inlet direction.

[0050] The other end of the heat dissipation air duct is provided with an air outlet. By also providing the air outlet on the side wall of the upper cover body and setting it away from the air inlet, that is, the air outlet faces away from the air inlet direction, the length of the heat dissipation air duct can be extended as much as possible to improve the heat dissipation effect. At the same time, this setting can also keep the air inlet and the air outlet as far away as possible, thereby avoiding the interference of the air flows at the air inlet and the air outlet and preventing the heat discharged from the air outlet from being sucked back into the device through the air inlet.

[0051] Optionally, the hot air module includes a hot air fan and a heating device, and the air fryer further includes: a second driving member located in the heat dissipation air duct and connected to the hot air fan to drive the hot air fan to rotate; a heat dissipation fan located in the heat dissipation air duct; the heat dissipation path of the heat dissipation air duct is formed such that cold air enters through the air inlet, the cold air flows through the second driving member, and then is driven by the heat dissipation fan and discharged from the air outlet.

[0052] In this technical solution, the hot air module includes a hot air fan and a heating device. The heating device is used to heat the gas, and the hot air fan is used to circulate the gas in the cooking cavity, so that hot air can be generated cyclically. The heat dissipation air duct includes an air inlet and an air outlet. The heat dissipation fan is used to make the air outside the air inlet enter the heat dissipation air duct, and then after passing through the components that need to be dissipated, it is discharged from the air outlet. Specifically, the second driving member, the electronic control board, etc. of the hot air fan can be installed in the heat dissipation air duct so as to be dissipated through the heat dissipation air duct. In addition, the heat dissipation air duct is located in the first cavity, that is, the heat dissipation air duct and the cooking cavity are respectively arranged in independent first and second cavities, so as to prevent the steam in the cooking cavity from entering the heat dissipation air duct and affecting the heat dissipation effect of the product.

[0053] Optionally, one end of the steam channel communicating with the outside is located on the top wall of the air fryer. This can make the discharged steam move upward from the top wall, so that it is not easy to be sucked into the heat dissipation air duct from the air inlet. In addition, a steam exhaust port is generally provided at one end of the steam channel communicating with the outside, and the steam exhaust port is arranged at the top, which can also prevent the steam from being discharged from the side and easily scalding the user. In addition, when adjusting the steam volume by adjusting the size of the steam exhaust port, arranging the steam exhaust port at the top can also facilitate the user to see the change in the opening size of the steam exhaust port, so as to facilitate guiding the user on how to operate the operation switch.

[0054] Optionally, the first opening includes a steam inlet. That is, the adjusting member can also be provided corresponding to the steam inlet, and then the opening size of the steam inlet is adjusted, so as to achieve the purpose of adjusting the steam discharge amount of the steam valve.

[0057] Optionally, the steam valve is detachably connected to the housing. That is, the steam valve can be integrally detached from the housing as a component. Further, the steam valve and the housing are in a quick-release connection, that is, without the aid of tools, the steam valve can be integrally detached, which facilitates the cleaning and replacement of the steam valve. Exemplarily, the steam valve and the housing can be connected by a buckle.

[0058] Optionally, the housing is provided with a mounting hole communicating with the first cavity, and the first end of the steam valve is located at the mounting hole. This setting enables one end of the steam valve to be exposed outside through the mounting hole. On the one hand, this enables the steam valve to be integrally detachable from the mounting hole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0070] To better understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0071] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0072] As Figure 1 and Figure 2 shown, an embodiment of the first aspect of the present invention provides an air fryer, which includes a cooking cavity 1, a hot air module 2, and a steam valve 3. Among them, the hot air module 2 is used to deliver hot air to the cooking cavity 1. The steam valve 3 includes a steam channel 30 and a movable adjusting member 32. The steam channel 30 is communicated with the cooking cavity 1. The steam channel 30 includes a first opening, and the adjusting member 32 can adjust the cross-sectional area of the steam channel 30 or the opening size of the first opening.

[0073] According to the air fryer provided by the present invention, it includes a cooking cavity 1, a hot air module 2, and a steam valve 3. Among them, the food to be cooked can be placed in the cooking cavity 1 for heating and baking. The hot air module 2 is used to generate hot air and circulate the hot air into the cooking cavity 1. The steam valve 3 can discharge the steam in the cooking cavity 1. During cooking, the amount of steam to be supplemented can be determined according to the type of food to be cooked, and then the cross-sectional area of the steam channel 30 or the opening size of the first opening can be comprehensively determined according to the amount of steam to be supplemented and the amount of steam that can be generated, so as to control the amount of steam that the steam valve 3 can discharge. For example, when cooking a certain kind of food and finding that the cooked food is relatively dry, the steam valve 3 can be closed to prevent steam from being discharged, so that the food can be hydrated by steam. On the contrary, if it is found that the cooked food is relatively moist and not crispy, then when cooking this kind of food next time, the steam valve 3 can be fully or partially opened to increase the amount of steam discharged during the cooking process. In addition, a first driving member can also be provided for the adjusting member 32. At this time, the opening state of the steam valve 3 can be automatically adjusted according to the food to be cooked, so as to realize the automatic adjustment of the steam amount.

[0074] Optionally, as Figure 1 shown, one end of the steam channel 30 away from the cooking cavity 1 is communicated to the outside. That is, the steam valve 3 can directly discharge the steam from the cooking cavity 1 to the outside of the device, so as to realize the temperature and humidity adjustment in the cooking cavity 1.

[0075] Optionally, as Figure 1As shown in the figure, the air fryer further includes: a housing 5 and a partition 6. The partition 6 is installed inside the housing 5 and divides the space inside the housing 5 into a first cavity and a second cavity. The cooking cavity 1 and the hot air module 2 are located in the second cavity. A steam inlet is provided on the partition 6. The steam valve 3 is attached to the partition 6, and the steam passage 30 of the steam valve 3 is communicated with the steam inlet on the partition 6.

[0076] In this embodiment, the internal space of the housing 5 is divided into two parts by the partition 6, namely the first cavity and the second cavity. Among them, the cooking cavity 1, the hot air module 2, etc. are installed in the second cavity, and this part of the space is mainly used for heating food ingredients. The first cavity is mainly used for placing electrical control components, such as the driving device of the hot air blower, the electronic control board, etc. And a steam inlet is provided on the partition 6, that is, the steam in the cooking cavity 1 can enter the steam valve 3 through the partition 6. With this kind of setting, since the steam passage 30 of the steam valve 3 is directly communicated with the steam inlet, the steam valve 3 has an independent passage to communicate with the cooking area to discharge the steam in the cooking cavity 1, thereby realizing the complete isolation of the steam passage 30 from the heat dissipation passage, thus solving the problem of the safety hazard that steam will enter the heat dissipation passage (i.e., the cold air duct), causing the heat dissipation passage to become hot, the heat dissipation function to decline, and the electrical components to overheat.

[0077] Further, a seal 7 is provided between the partition 6 and the steam valve 3, and the seal 7 can make the partition 6 and the steam valve 3 be sealed and connected, so as to ensure that the steam will not leak into the first cavity.

[0078] Further, the partition 6 and the housing 5 are sealed and connected, that is, the first cavity and the second cavity are disconnected and not communicated with each other, that is, the steam in the cooking cavity 1 cannot enter the first cavity, so that the steam can be prevented from entering the heat dissipation air duct and causing the heat dissipation air duct to become hot. In this way, the heat dissipation efficiency of the product can be ensured, and the safety hazard of electrical components overheating can be avoided.

[0079] Optionally, as Figure 2 shown, a shielding member 322 is provided at one end of the adjusting member 32. When the shielding member 322 moves along the first direction (such as Figure 2 the A direction in the figure), the opening area of the first opening gradually decreases, and when the shielding member 322 moves along the second direction, the opening area of the first opening gradually increases; wherein, the first direction and the second direction are opposite to each other.

[0080] In this embodiment, the adjusting member 32 includes the shielding member 322, that is, the structure for shielding the steam passage 30. At the same time, the shielding member 322 can move back and forth along the first direction and the second direction so as to be able to adjust the opening area of the first opening. With this kind of setting, by the back-and-forth movement of the adjusting member 32, the increase or decrease adjustment of the opening size of the first opening can be realized.

[0081] Optionally, an operation switch 38 is provided at one end of the adjusting member 32 away from the first opening along the first direction. The operation switch 38 can drive the shielding member 322 to move along the first direction or the second direction.

[0082] In this embodiment, the operation switch 38 can be used to push the shielding member 322 to move, so as to adjust the opening size of the first opening. The setting of the operation switch 38 enables the user to manually drive the shielding member 322, thereby realizing the manual control of the steam volume.

[0083] Optionally, as Figure 2 shown, the steam valve 3 further includes a detection member 4. A trigger position 324 is provided on the adjusting member 32. The trigger position 324 is used to trigger the detection member 4 during the movement process to prompt the position of the shielding member 322. Optionally, the air fryer further includes: a control device 10, connected to the detection member 4, and capable of controlling the humidity of the cooking cavity of the air fryer according to the detection result of the detection member 4.

[0084] In this embodiment, the detection member 4 is used to detect the position of the adjusting member 32, and the opening size of the first opening can be determined according to this position. For example, at least one travel switch can be provided on the movement track of the adjusting member 32, and then the corresponding travel switch can be triggered by the trigger position 324, so that the position of the adjusting member 32 can be determined by whether the travel switch is triggered. After determining the position of the shielding member 322, the control device 10 can be used to control the operation of the whole product. For example, controlling the heating power of the product, controlling the generation amount of steam, etc. The control device 10 can also control the steam volume according to the position of the adjusting member 32. For example, controlling the generation amount of steam or controlling the heating power of the food materials, etc., so as to control the humidity in the cooking cavity 1. Of course, in the case where the adjusting member 32 can be automatically adjusted, the position of the adjusting member 32 can also be determined according to the position of the adjusting member 32 to control the movement of the adjusting member 32.

[0085] In addition, the control device 10 can also adjust the cooking program according to whether the detection member 4 is triggered or the degree of triggering, thereby improving the food taste.

[0086] Optionally, as Figure 2 shown, the trigger position 324 is a first protrusion formed by the shielding member 322 perpendicular to the first direction and facing away from the first opening. The top end of the first protrusion has a curved surface or an inclined surface for triggering the detection member 4.

[0087] In this embodiment, a protrusion can be provided on the shielding member 322 to trigger the detection member 4. In order to facilitate the smooth cooperation between the protrusion and the detection member 4, the top surface of the protrusion can be set as a curved surface or an inclined surface to ensure that the protrusion can normally trigger the detection member 4 without interfering with the detection member 4 and getting stuck.

[0088] Optionally, as Figure 2 shown, a through hole 344 is provided at the position of the valve seat 34 corresponding to the detection member 4. The through hole 344 is used for the detection member 4 to trigger the trigger position 324. Through the setting of the through hole 344, the shielding member 322 and the detection member 4 can be in normal contact and thus be triggered, so that the position detection of the shielding member 322 can be simply and conveniently realized.

[0089] Optionally, as Figure 2 shown, the steam valve 3 further includes a valve seat 34 and a valve cover 36. The valve cover 36 is installed on the valve seat 34, and an exhaust port 362 is provided on the valve cover 36. The steam passage 30 is surrounded by the valve cover 36 and the valve seat 34 and is communicated with the exhaust port 362.

[0090] In this embodiment, the valve seat 34 and the valve cover 36 form the outer shell structure of a steam valve 3, and a steam passage can be defined by the valve seat 34 and the valve cover 36 to realize the discharge of steam. At the same time, an exhaust port 362 is provided on the valve cover 36, and the steam in the steam passage 30 can be discharged to the outside through the exhaust port 362.

[0091] Optionally, as Figure 2 shown, the adjusting member 32 is movably arranged between the valve seat 34 and the valve cover 36. That is, the adjusting member 32 is installed inside the valve seat 34 and the valve cover 36, so that the opening size of the first opening can be adjusted from the inside of the valve seat 34 and the valve cover 36. Of course, in other embodiments, the adjusting member 32 can also be arranged outside the valve cover 36. For example, when the adjusting member 32 is used to adjust the opening size of the exhaust port 362, the adjusting member 32 can be arranged outside the valve cover 36.

[0092] Wherein, the adjusting member 32 can close or open the first opening. In addition, the adjusting member 32 can also include multiple positions, so that in addition to being able to open and close the first opening, the adjusting member 32 can also divide the opening size of the first opening into different gears, thereby enabling more precise adjustment of the steam volume.

[0093] Optionally, as Figure 2 shown, the first opening includes the exhaust port 362, that is, the adjusting member 32 is arranged corresponding to the exhaust port 362 for adjusting the opening size of the exhaust port 362.

[0094] Since the exhaust port 362 is generally arranged on the outer surface of the device, therefore, arranging the adjusting member 32 corresponding to the exhaust port 362 can make the adjusting member 32 closer to the outer surface of the device. On the one hand, it is convenient for the user to manually adjust the position of the adjusting member 32 to adjust the opening size of the exhaust port 362. On the other hand, when the product is not in use, the exhaust port 362 can be completely closed by the adjusting member 32 to prevent external dust and the like from entering the steam valve 3.

[0095] Alternatively, if Figure 2 As shown, the adjusting member 32 is movably arranged between the valve seat 34 and the valve cover 36, and an operating window 364 is arranged on the valve cover 36, and the operating window 364 is a clearance position formed by the valve cover 36 being recessed toward the valve seat 34; the operating switch 38 is movably mounted on the valve cover 36 and / or the valve seat 34, and is located in the clearance position, and the length of the clearance position along the first direction is greater than or equal to the sum of the length of the operating switch 38 along the first direction and the stroke length of the operating switch 38 along the first direction.

[0096] In this embodiment, the operating switch 38 is movably mounted on the valve cover 36 so that the operating switch 38 can be exposed outside, which is convenient for the user to manually operate the operating switch 38, thereby realizing manual adjustment of the steam volume. The operating window 364 is a clearance position formed by the valve cover 36 being recessed toward the valve seat 34, thereby preventing the operating switch 38 from protruding too much from the valve cover 36. The length of the clearance position along the first direction is greater than or equal to the sum of the length of the operating switch 38 along the first direction and the stroke length of the operating switch 38 along the first direction, ensuring that the operating switch 38 can move normally in the clearance position, thereby realizing the size adjustment of the opening area of the steam channel 30.

[0097] Alternatively, if Figure 2 As shown, a push button 382 is provided on the upper surface of the operating switch 38. The push button 382 can be used to push the operating switch 38, so that the opening area of the steam valve 3 can be adjusted simply and conveniently.

[0098] Alternatively, if Figure 2 As shown, the push button 382 is a second protrusion formed on the upper surface of the operating switch 38 in a direction perpendicular to the first direction and away from the cooking cavity. The second protrusion provides a force point for the user to push the operating switch 38, thereby making the operation of the operating switch 38 more convenient.

[0099] Optionally, there is a transition arc between the second protrusion and the operating switch 38. The transition arc can make the transition between the operating switch 38 and the second protrusion smoother, thereby improving the appearance of the entire switch.

[0100] Optionally, a guide member that cooperates with each other is provided between the operating switch 38 and the valve cover 36, and the guide member includes a guide groove and a guide protrusion that adapt to each other, one of the guide groove and the guide protrusion is provided on the valve cover 36, and the other of the guide groove and the guide protrusion is provided on the operating switch 38. By providing the guide member, the operating switch 38 can move more smoothly on the valve cover 36, and the risk of the operating switch 38 being offset during movement can be avoided, thereby avoiding the risk of the operating switch 38 being stuck, and thus making the operating switch 38 more durable.

[0101] Optionally, the valve seat 34 and the valve cover 36 are detachably connected by snaps. The valve cover 36 can be detached from the valve seat 34 separately for cleaning.

[0102] Optionally, the air fryer further includes a first driving member (not shown in the figure), which is connected to the adjusting member 32 and is used to drive the adjusting member 32 to move.

[0103] In this embodiment, the first driving member can drive the adjusting member 32 to move, so that the opening size of the steam valve 3 can be automatically adjusted without manual adjustment by the user, and thus the steam volume can be controlled more precisely.

[0104] Optionally, as Figure 2 and Figure 3 shown, the steam valve 3 further includes a detecting member 4, which is arranged corresponding to the adjusting member 32 and can detect the position of the adjusting member 32. The air fryer further includes a control device 10, which is connected to the detecting member 4 and can control the steam volume of the air fryer according to the detection result of the detecting member 4.

[0105] In this embodiment, the detecting member 4 is used to detect the position of the adjusting member 32, and the opening size of the first opening can be determined according to this position. For example, at least one travel switch can be arranged on the movement track of the adjusting member 32, and then the position of the adjusting member 32 can be determined by the travel switch. The control device 10 is used to control the operation of the whole product. For example, it controls the heating power of the product and the generation amount of steam, etc. The control device 10 can also control the steam volume according to the position of the adjusting member 32. For example, it controls the generation amount of steam or the heating power of the food ingredients, etc. Of course, when the adjusting member 32 can be automatically adjusted, the position of the adjusting member 32 can also be used to determine whether the adjusting member 32 has moved in place, so as to control the movement of the adjusting member 32.

[0106] Optionally, the air fryer further includes: a heat dissipation air duct, and the heat dissipation air duct is independently arranged from the steam channel 30.

[0107] In this embodiment, the hot air module 2 includes a hot air fan 22 and a heating device 24. The heating device 24 is used to heat the gas, and the hot air fan 22 is used to circulate the gas in the cooking cavity 1, so that hot air can be generated cyclically. The heat dissipation air duct includes an air inlet and an air outlet 94. The heat dissipation fan 92 is used to make the air outside the air inlet enter the heat dissipation air duct, and then discharge from the air outlet 94 after passing through the components that need to be dissipated. Specifically, the second driving member 8, the electronic control board, etc. of the hot air fan 22 can be installed in the heat dissipation air duct so as to dissipate heat through the heat dissipation air duct. The heat dissipation air duct is independently arranged from the steam channel 30, which can prevent steam from entering the heat dissipation air duct, thereby preventing the steam in the cooking cavity 1 from entering the heat dissipation air duct and affecting the heat dissipation effect of the product. Thus, the problem that in the related solutions, steam easily enters the heat dissipation air duct, resulting in a reduction in the heat dissipation effect and easy damage to the parts in the heat dissipation air duct can be solved.

[0108] Optionally, as Figure 1 shown, the air fryer further includes: a housing 5; a partition 6, installed in the housing 5 and dividing the space in the housing 5 into a first cavity and a second cavity. The cooking cavity 1 and the hot air module 2 are located in the second cavity. A steam inlet is provided on the partition 6. The steam valve 3 includes an extension 342, the extension 342 is attached to the partition 6, and the steam channel 30 includes a steam inlet channel 302 located in the extension 342, and the steam inlet channel 302 is communicated with the steam inlet; a seal 7 is provided between the partition 6 and the extension 342 for making a sealed connection between the partition 6 and the extension 342.

[0109] In this embodiment, the internal space of the housing 5 is divided into two parts by the partition 6, namely the first cavity and the second cavity. Among them, the cooking cavity 1, the hot air module 2, etc. are installed in the second cavity, and this part of the space is mainly used for heating food ingredients. The first cavity is mainly used for placing electrical controls, such as the driving device of the hot air fan and the electronic control board. A steam inlet is provided on the partition 6, that is, the steam in the cooking cavity 1 can enter the steam valve 3 through the partition 6. Specifically, the steam valve 3 includes an extension 342 with a steam inlet channel 302. The steam valve 3 is attached to the partition 6 through the extension 342 and is communicated with the cooking cavity 1 through the extension 342. In addition, a seal 7 is provided between the partition 6 and the extension 342, and the seal 7 can make a sealed connection between the partition 6 and the extension 342, so as to ensure that steam will not leak into the first cavity.

[0110] Furthermore, the partition 6 and the housing 5 are sealed, that is, the first cavity and the second cavity are disconnected and not communicated with each other, that is, the steam in the cooking cavity 1 cannot enter the first cavity, so that steam can be prevented from entering the heat dissipation air duct and causing the heat dissipation air duct to become hot. In this way, the heat dissipation efficiency of the product can be ensured, and the safety hazard caused by overheating of electrical components can be avoided.

[0111] Optionally, as Figure 1 shown, the partition 6 includes: a reflector 62 located on the side of the hot air module 2 away from the cooking cavity 1, and a steam inlet is provided on the reflector 62.

[0113] Optionally, the heat dissipation air duct includes an air inlet. The housing 5 includes an upper cover 54. The upper cover 54 includes a top cover 542 and a side wall 544 of the upper cover 54. The air inlet is provided on the side wall 544 of the upper cover 54.

[0114] The upper cover 54 includes a top cover 542 and a side wall 544. One end of the heat dissipation air duct is provided with an air inlet. The one end of the heat dissipation air duct can be extended to the side wall 544 of the upper cover 54 to facilitate the inflow of air. At the same time, the exhaust port 362 of the steam valve 3 can be provided on the top of the upper cover 54, so that the exhaust port 362 and the air inlet are relatively far away from each other, avoiding the steam discharged being sucked into the heat dissipation air duct.

[0115] Optionally, the side wall 544 of the upper cover 54 is formed as an inclined wall that slopes from top to bottom towards the axis direction of the air fryer, and the air inlet is provided on the inclined wall.

[0116] In this solution, the side wall 544 is inclined and the inclined direction is inward. The upper cover 54 has a shape that is wider at the top and narrower at the bottom. By providing the air inlet on the inclined wall, on the one hand, it can play a certain guiding role to facilitate the inflow of air, and on the other hand, the wider structure on the upper side can block a part of the naturally falling dust, avoiding the dust from entering through the air inlet and affecting the heat dissipation fan, etc.

[0117] Optionally, the heat dissipation air duct includes an air outlet 94; the air outlet 94 is located on the side wall 544 of the upper cover 54 and faces away from the air inlet direction.

[0118] The other end of the heat dissipation air duct is provided with an air outlet 94. By also providing the air outlet 94 on the side wall 544 of the upper cover 54 and setting it away from the air inlet, that is, the air outlet 94 faces away from the air inlet direction, the length of the heat dissipation air duct can be extended as much as possible to improve the heat dissipation effect. At the same time, this kind of setting can also make the air inlet and the air outlet 94 as far away as possible, so as to avoid the interference of the air flow between the air inlet and the air outlet 94 and prevent the heat discharged from the air outlet 94 from being sucked back into the device through the air inlet.

[0119] Optionally, the hot air module 2 includes a hot air fan 22 and a heating device 24. The air fryer further includes: a second driving member 8 located in the heat dissipation air duct and connected to the hot air fan 22 to drive the hot air fan 22 to rotate; a heat dissipation fan 92 located in the heat dissipation air duct; the heat dissipation path of the heat dissipation air duct is formed such that cold air enters from the air inlet, the cold air flows through the second driving member 8, and then is driven by the heat dissipation fan 92 and discharged from the air outlet 94.

[0120] In this embodiment, the hot air module 2 includes a hot air fan 22 and a heating device 24. The heating device 24 is used to heat the gas, and the hot air fan 22 is used to circulate the gas in the cooking cavity 1, so that hot air can be circulated and generated. The heat dissipation air duct includes an air inlet and an air outlet 94. The heat dissipation fan 92 is used to allow the air outside the air inlet to enter the heat dissipation air duct, and then after passing through the components that need to be dissipated, it is discharged from the air outlet 94. Specifically, the second driving member 8 of the hot air fan 22, the electronic control board, etc. can be installed in the heat dissipation air duct so as to be dissipated through the heat dissipation air duct. In addition, the heat dissipation air duct is located in the first cavity, that is, the heat dissipation air duct and the cooking cavity 1 are respectively arranged in independent first and second cavities, so as to prevent the steam in the cooking cavity 1 from entering the heat dissipation air duct and affecting the heat dissipation effect of the product.

[0121] Optionally, one end of the steam channel 30 communicating with the outside is located on the top wall of the air fryer. This can enable the discharged steam to move upward from the top wall, so that it is not easily sucked into the heat dissipation air duct from the air inlet. In addition, a steam exhaust port 362 is generally provided at one end of the steam channel 30 communicating with the outside. The steam exhaust port 362 is provided at the top, which can also prevent the steam from being discharged from the side and easily scalding the user. In addition, when adjusting the steam volume by adjusting the size of the steam exhaust port 362, the steam exhaust port 362 being provided at the top can also facilitate the user to see the opening of the steam exhaust port 362.

[0122] Optionally, the first opening includes a steam inlet. That is, the adjusting member 32 can also be provided corresponding to the steam inlet, and then the opening size of the steam inlet is adjusted, so as to also achieve the purpose of adjusting the steam discharge amount of the steam valve 3.

[0123] Exemplarily, the first opening only includes a steam inlet or only includes the steam exhaust port 362.

[0124] Exemplarily, the first opening includes both a steam inlet and a steam exhaust port 362 at the same time.

[0125] Optionally, the steam valve 3 is detachably connected to the housing 5. That is, the steam valve 3 can be integrally detached from the housing 5 as a component. Further, the steam valve 3 and the housing 5 are connected in a quick-release manner, that is, without the aid of tools, the steam valve 3 can be integrally detached, which facilitates the cleaning and replacement of the steam valve 3. Exemplarily, the steam valve 3 and the housing 5 can be connected by a snap connection.

[0126] Optionally, as Figure 1 shown, the hot air module 2 includes a hot air fan 22 and a heating device 24. The air fryer further includes: a heat dissipation air duct located in the first cavity; a second driving member 8 located in the heat dissipation air duct and connected to the hot air fan 22 to drive the hot air fan 22 to rotate; and a heat dissipation fan 92 located in the heat dissipation air duct. The heat dissipation fan 92 is configured to cause the air in the heat dissipation air duct to flow from the inlet to the outlet.

[0127] In this embodiment, the hot air module 2 includes a hot air fan 22 and a heating device 24. The heating device 24 is configured to heat the gas, and the hot air fan 22 is configured to circulate the gas in the cooking cavity 1, so that hot air can be circulated and generated. The heat dissipation air duct includes an air inlet and an air outlet. The heat dissipation fan 92 is configured to cause the air outside the air inlet to enter the heat dissipation air duct, and then discharge from the air outlet after passing through the components that need to be dissipated. Specifically, the second driving member 8 of the hot air fan 22, the electronic control board, etc. can be installed in the heat dissipation air duct so as to dissipate heat through the heat dissipation air duct. In addition, the heat dissipation air duct is located in the first cavity, that is, the heat dissipation air duct and the cooking cavity 1 are respectively arranged in independent first and second cavities, so as to prevent the steam in the cooking cavity 1 from entering the heat dissipation air duct and affecting the heat dissipation effect of the product.

[0128] Optionally, the housing 5 is provided with a mounting hole 52 communicating with the first cavity, and the first end of the steam valve 3 is located at the mounting hole 52. With this arrangement, one end of the steam valve 3 can be exposed outside through the mounting hole 52. On the one hand, this enables the steam valve 3 to be integrally detachable from the mounting hole 52. On the other hand, it also facilitates directly arranging the exhaust port 362 of the steam valve 3 outside to facilitate direct discharge of steam.

[0129] Optionally, the exhaust port 362 of the steam channel 30 is located on the end face of the first end of the steam valve 3. Of course, it can also be located on the side face of the first end of the steam valve 3.

[0130] Optionally, the mounting hole 52 is located at the top of the air fryer or on the side wall of the air fryer, that is, the steam valve 3 can be arranged vertically or horizontally.

[0131] Optionally, the air fryer includes a steam air fryer.

[0132] Optionally, the upper end of the cooking cavity 1 is open, and the hot air module 2 is located above the cooking cavity 1. The partition 6 is arranged horizontally (i.e., parallel or quasi-parallel to the cross-section of the cooking cavity 1), so that the first cavity and the second cavity are arranged in the up and down direction.

[0133] As Figure 1 and Figure 2 shown, the air fryer of the present application will be further introduced below taking the air fryer as an example.

[0134] Among them, adding steam to a traditional air fryer can make the food softer and more delicious. When food is cooked at high temperatures, they lose moisture and become dry. However, adding steam can help retain the moisture in the food, making it softer and juicier. In addition, steam can also make the food cook more evenly because it can fill the air bubbles on the surface of the food. But different ingredients have different requirements for steam, and the taste of the food cooked with different amounts of steam is completely different. To achieve adjustable taste, this embodiment provides an air fryer including a steam-adjustable exhaust valve to achieve this function.

[0135] Among them, this embodiment provides an air fryer with steam, and its structure includes a motor (equivalent to the second driving member 8), a top cover, an upper cover, a viewing window, a cold air blade (equivalent to the heat dissipation fan 92), a reflector 62, a heat pipe (equivalent to the heating device 24), a frying bucket (equivalent to the cooking cavity 1), a baking tray, an outer pot, a hot plate, a base, a steam valve 3, a sealing ring (i.e., the sealing member 7), an exhaust window (i.e., the exhaust passage 94), and a hot air blade (equivalent to the hot air fan 22). The steam valve 3 is composed of a steam valve upper cover (equivalent to the valve cover 36), a steam valve push button (which belongs to one kind of the operation switch 38), a valve seat 34, and an adjusting plate (which belongs to one kind of the adjusting member 32).

[0136] Among them, the steam valve push button drives the adjusting plate to act, thereby adjusting the size of the steam outlet on the steam valve upper cover, so as to control the amount of steam.

[0137] Furthermore, the steam valve 3 is provided with a steam inlet on the valve seat 34 and a steam outlet on the steam upper cover. The adjusting plate is placed between the steam valve upper cover and the valve seat 34. The steam valve push button can drive the adjusting plate to adjust the size of the steam passage 30, so as to control the amount of steam. For example, the size of the steam outlet can be adjusted, or the size of the steam inlet can also be adjusted. Of course, the sizes of the inlet and outlet can also be adjusted simultaneously. The steam valve upper cover can be directly separated from the valve seat 34. The edge of the steam valve upper cover is provided with a groove, and the valve seat 34 is provided with a convex structure. The groove and the convex structure cooperate to connect and fix the steam valve upper cover and the valve seat 34.

[0138] Furthermore, the steam valve push button can be driven by pressing up and down, rotating, driving forward or backward, or driving left and right.

[0139] Furthermore, the adjusting plate can adjust the size of the inlet and outlet channels in the up and down direction, or it can be in the rotational direction or translate on a certain plane in space to adjust the size of the inlet and outlet channels.

[0140] Furthermore, the upper cover can be separated from the valve seat 34 for cleaning.

[0141] The air fryer of this embodiment has an adjustable steam volume. Therefore, when cooking food, the opening of the steam valve 3 can be adjusted manually or automatically according to the specific food to adjust the steam discharge volume, so that the remaining steam volume in the cooking cavity 1 is more matched with the food, thereby improving the cooking effect of the food and improving the cooking taste of the food.

[0142] Furthermore, if the cold air duct is connected to the steam channel 30, steam will enter the cold air duct, causing the cold air duct to heat up and reduce the heat dissipation function, thereby causing the electrical components to overheat and create safety hazards. In order to solve the adverse effects of adding steam on the whole machine, this embodiment further improves the air fryer, and its solution is as follows:

[0143] The steam valve 3 has an independent channel connected to the cooking area of the frying bucket, which is used to discharge the steam in the frying bucket. The steam valve 3 can be completely separated from the body (detachable). The steam valve 3 is placed on the reflective cover 62, and an opening is provided on the top or side of the reflective cover 62. The sealing ring is placed between the steam valve 3 and the reflective cover 62. The steam valve 3 penetrates the exhaust window and contacts the top cover (the steam valve 3 can also be staggered with the exhaust window and does not need to penetrate the exhaust window). This arrangement realizes the complete isolation of the steam channel 30 from the heat dissipation channel, and solves the problem that steam will enter the cold air duct, causing the cold air duct to become hot, the heat dissipation function to decrease, and the safety hazard of overheating of electrical components.

[0144] Optionally, the steam valve 3 can be placed on the side wall of the entire air fryer and can be drawn out, or can be placed on the top of the entire air fryer and can be drawn out.
