Description

Technical Field

[0001] The embodiments of the present application relate to home appliance technology, and more particularly to a steam oven. Background Art

[0002] With the development of people's economic level, more and more household appliances are used in ordinary families. As a commonly used kitchen appliance, steam ovens are becoming more and more popular.

[0003] In related art, a steam oven includes a housing and a steam system, a baking system, and a humidity sensor located within the housing. The housing includes an inner container, which defines a cooking cavity. The humidity sensor is inserted into the inner container, with a detection end located within the cooking cavity, and is used to detect humidity within the cooking cavity.

[0004] However, humidity sensors have a short service life. Utility Model Content

[0005] The embodiment of the present application provides a steam oven, and the humidity sensor has a long service life.

[0006] In a first aspect, an embodiment of the present application provides a steam oven, comprising:

[0007] The box body includes an outer shell and an inner liner, the outer shell is configured with a receiving cavity, the inner liner is located in the receiving cavity, and the inner liner is configured with a cooking cavity;

[0008] An air duct assembly is located in the accommodating cavity and on one side of the inner pot. The air duct assembly is constructed with an air duct cavity, which is connected to the cooking cavity;

[0009] The humidity detection component is located in the accommodating cavity and includes:

[0010] A protective member, the protective member is constructed with a protective cavity, a first opening and a second opening, the first opening connecting the protective cavity and the cooking cavity, and the second opening connecting the protective cavity and the air duct cavity;

[0011] Humidity sensor, the detection end of the humidity sensor is located in the protective cavity;

[0012] driving parts;

[0013] The first sealing member is connected to the driving member, the first sealing member is close to the first opening, and the driving member drives the first sealing member to move relative to the protective member to connect or disconnect the protective cavity with the cooking cavity.

[0014] In this way, the humidity sensor does not need to detect the humidity of the cooking cavity. The driving member drives the first sealing member to move relative to the protective member to close the first opening. The protective cavity and the cooking cavity are not connected, and the air in the cooking cavity cannot enter the protective cavity, thereby effectively avoiding the influence of oil smoke on the humidity sensor, which is beneficial to improving the service life of the humidity sensor.

[0015] In some embodiments of the present application, the driving member drives the first sealing member to move relative to the protective member, so that the protective cavity is connected to the cooking cavity or not connected.

[0016] In this way, the first sealing member does not need to be rotationally connected to the protective member, which is beneficial to simplifying the structure and improving reliability.

[0017] In some embodiments of the present application, the driving member is located on a side of the air duct assembly facing away from the inner tank, the driving member is connected to the air duct assembly, and a portion of the driving shaft of the driving member is located in the air duct cavity;

[0018] The first sealing member is connected to the driving shaft, and at least a portion of the first sealing member is located in the protective cavity. The driving member drives the first sealing member to move closer to or away from the air duct assembly to connect or disconnect the protective cavity with the cooking cavity.

[0019] In this way, the driving parts are not easily affected by steam and oil smoke.

[0020] In some embodiments of the present application, the inner pot is configured with a third opening, the third opening is connected to the cooking cavity, the protective member is connected to the outer wall of the inner pot, and the first opening is opposite to and connected to the third opening.

[0021] In this way, there is no need to use additional pipes for connection, the structure is simple and the cost is low.

[0022] In some embodiments of the present application, the first sealing member includes a first connecting portion and a second connecting portion connected to each other, an end of the first connecting portion facing away from the second connecting portion is connected to the driving member, and the first connecting portion is inserted into the first opening and the third opening;

[0023] The orthographic projection of the inner wall of the third opening toward the plane where the first end surface is located is located within the first end surface, wherein the first end surface is the end surface of the second connecting portion facing the first connecting portion, and the second connecting portion is located within the cooking cavity;

[0024] The driving member drives the second connecting portion to abut against or disengage from the inner wall of the inner pot through the first connecting portion, so that the protection cavity is connected to or disconnected from the cooking cavity.

[0025] In this way, the contact area between the second connecting portion and the inner wall of the liner is larger, which is beneficial to improving the sealing effect.

[0026] In some embodiments of the present application, the third opening is circular and the first end surface is circular.

[0027] It is understandable that when the humidity detection component has an installation error or rotates during use, the second connection portion can still effectively seal the third opening.

[0028] In some embodiments of the present application, at least part of the protective member is located in the air duct cavity, and the second opening is located in the air duct cavity.

[0029] In this way, there is no need to use additional pipes for connection, the structure is simple and the cost is low.

[0030] In some embodiments of the present application, a second sealing member is further included, the second sealing member being connected to the driving member and the first sealing member, and the second sealing member being located on a side of the protective member facing away from the inner container;

[0031] The driving member drives the second sealing member to move relative to the protective member, so that the protective cavity is connected to the air duct cavity or is disconnected.

[0032] In this way, when in steam mode, the second sealing member prevents the protective cavity from communicating with the air duct cavity, and the steam in the cooking cavity is not easy to enter the air duct cavity through the protective cavity, causing heat loss.

[0033] In some embodiments of the present application, the humidity sensor is connected to the second sealing member.

[0034] In this way, the humidity sensor can be moved under the action of the driving member, so that when no measurement is needed, the humidity sensor can be kept at a greater distance from the inner container, thereby reducing the influence of the temperature of the inner container on the humidity sensor.

[0035] In a second aspect, an embodiment of the present application provides a steam oven, comprising:

[0036] The box body includes an inner container, and the inner container is configured with a cooking cavity;

[0037] The air duct assembly is located in the box body and on one side of the inner pot. The air duct assembly is constructed with an air duct cavity, which is connected to the cooking cavity;

[0038] Humidity detection component, the humidity detection component is located in the box, the humidity detection component includes:

[0039] A protective member having a protective cavity connected to the air duct cavity;

[0040] Humidity sensor, the detection end of the humidity sensor is located in the protective cavity;

[0041] driving parts;

[0042] The first sealing member is connected to the driving member, and the driving member drives the first sealing member to move relative to the protective member to connect or disconnect the protective cavity and the cooking cavity.

[0043] In this way, the humidity sensor does not need to detect the humidity of the cooking cavity. The driving member drives the first sealing member to move relative to the protective member so that the protective cavity and the cooking cavity are not connected, and the air in the cooking cavity cannot enter the protective cavity, thereby effectively avoiding the influence of oil smoke on the humidity sensor, which is beneficial to improving the life of the humidity sensor.

DETAILED DESCRIPTION

[0062] As described in the background art, the humidity sensor in the current steam oven is of fixed design. During long-term use, especially when baking meat, a large amount of grease will adhere to the surface of the humidity sensor, causing the humidity sensor to fail.

[0063] To address the aforementioned technical issues, the present application designs the humidity detection assembly as a movable structure. When the humidity sensor needs to detect humidity, a driver drives the first sealing member to move relative to the protective member, thereby connecting the protective cavity and the cooking cavity. Air from the cooking cavity enters the protective cavity, allowing the humidity sensor to detect humidity. When the humidity sensor does not need to detect humidity in the cooking cavity, the driver drives the first sealing member to move relative to the protective member, disconnecting the protective cavity and the cooking cavity. Air from the cooking cavity cannot enter the protective cavity, thereby effectively preventing the influence of oil smoke on the humidity sensor and improving the life of the humidity sensor.

Figure 7 for Figure 6 A partial enlarged view of point C in the middle. Figure 8 This is a schematic structural diagram of the humidity detection component in the steam oven provided in an embodiment of the present application.

[0118] See also Figures 6 to 8 As shown, in some embodiments, the steam oven includes: a humidity detection component 600. The humidity detection component 600 is used to detect the humidity in the cooking cavity 121.

[0119] The humidity detection component 600 is located in the accommodating cavity.

[0120] In some embodiments, the humidity detection component 600 is electrically connected to a control system, which controls the amount of steam inputted into the cooking cavity 121 by the steam system 300 according to the humidity value detected by the humidity detection component 600 .

[0121] Figure 9 This is a schematic diagram of the structure of the protective component in the steam oven provided in an embodiment of the present application.

[0122] See also Figures 5 to 9As shown, in some embodiments, the humidity detection assembly 600 includes a protective member 610 , which is used to protect the humidity sensor 620 .

[0123] The protective member 610 is configured with a protective cavity 611 , which is communicated with the air duct cavity 510 .

[0124] The protection member 610 is configured with a first opening 612 . The first opening 612 connects the protection cavity 611 and the cooking cavity 121 .

[0125] For example, the first opening 612 may be a circular hole, a rectangular hole, or an irregular hole.

[0126] The protective member 610 is configured with a second opening 613 . The second opening 613 communicates with the protective cavity 611 and the air duct cavity 510 .

[0127] Exemplarily, the second opening 613 may be a circular hole, a rectangular hole, or an irregular hole.

[0128] See also Figures 5 to 8 As shown, in some embodiments, the humidity detection component 600 includes a humidity sensor 620 , and a detection end of the humidity sensor 620 is located in the protective cavity 611 .

[0129] It is understandable that the humidity sensor 620 can be installed in the protective cavity 611 . Alternatively, the humidity sensor 620 can be inserted into the protective member 610 so that the detection end of the humidity sensor 620 is located in the protective cavity 611 .

[0130] In some embodiments, the humidity detection assembly 600 includes a driving member 630 .

[0131] In some embodiments, the humidity detection assembly 600 includes a first seal 640 .

[0132] The driving member 630 drives the first sealing member 640 to move relative to the protective member 610 so that the protective cavity 611 and the cooking cavity 121 are connected or disconnected.

[0133] Specifically, the driving member 630 is connected to the first sealing member 640 . The first sealing member 640 is close to or covers the first opening 612 . The driving member 630 drives the first sealing member 640 to move relative to the protective member 610 to open or close the first opening 612 .

[0134] During steam cooking, the driver 630 drives the first sealing member 640 to move relative to the protective member 610, opening the first opening 612. This connects the protective cavity 611 with the cooking cavity 121, allowing air from the cooking cavity 121 to enter the protective cavity 611. The humidity sensor 620 detects the humidity in the cooking cavity 121. Furthermore, the air flows through the air duct cavity 510 to the outside of the steam oven.

[0135] During baking and cooking, the humidity sensor 620 does not need to detect the humidity of the cooking cavity 121. The driving member 630 drives the first sealing member 640 to move relative to the protective member 610 to close the first opening 612. The protective cavity 611 and the cooking cavity 121 are not connected, and the air in the cooking cavity 121 cannot enter the protective cavity 611.

[0136] It is understandable that when baking and cooking, the oil smoke in the cooking cavity 121 can be effectively prevented from reaching the position of the humidity sensor 620, and the grease can be effectively prevented from adhering to the surface of the humidity sensor 620, causing the humidity sensor 620 to fail.

[0137] Moreover, the air in the cooking cavity 121 flows to the outside of the steam oven through the protective cavity 611 and the air duct cavity 510, and is not easy to flow to other positions of the accommodating cavity, affecting the electrical components in the accommodating cavity, which is beneficial to improving the service life of the electrical components.

[0138] In some embodiments of the present application, the driving member 630 drives the first sealing member 640 to rotate relative to the protective member 610, so that the protective cavity 611 is connected to the cooking cavity 121 or is not connected.

[0139] Specifically, the first seal 640 is located outside the protective member 610 and at the end. The first seal 640 covers the first opening 612. The first seal 640 is hinged to the protective member 610. The driving shaft of the driving member 630 moves linearly. After the driving shaft contacts the first seal 640, it drives the first seal 640 to rotate relative to the protective member 610, thereby opening the first opening 612.

[0140] Alternatively, the first seal 640 is located inside the protective member 610, the first seal 640 is close to the first opening 612, the first seal 640 is hinged to the protective member 610, the driving shaft of the driving member 630 moves linearly, and after the driving shaft contacts the first seal 640, it drives the first seal 640 to rotate relative to the protective member 610, thereby opening the first opening 612.

[0141] In some embodiments of the present application, the driving member 630 drives the first sealing member 640 to move relative to the protective member 610 to connect or disconnect the protective cavity 611 with the cooking cavity 121 .

[0142] Specifically, the first seal 640 is located outside the protective member 610 and at the end. The first seal 640 covers the first opening 612. The first seal 640 is connected to the driving shaft of the driving member 630. The driving shaft of the driving member 630 moves linearly, and the driving shaft drives the first seal 640 to move relative to the protective member 610, thereby opening the first opening 612.

[0143] Alternatively, the first sealing member 640 is inserted into the protective member 610 and is slidingly connected to the protective member 610. The first sealing member 640 is close to the first opening 612. The first sealing member 640 is connected to the driving shaft of the driving member 630. The driving shaft of the driving member 630 moves linearly, and the driving shaft drives the first sealing member 640 to move relative to the protective member 610, thereby opening the first opening 612.

[0144] See also Figures 5 to 9 As shown, in some embodiments of the present application, the driving member 630 is located on a side of the air duct assembly 500 facing away from the inner pot 120. The driving member 630 is connected to the air duct assembly 500, and a portion of the driving shaft of the driving member 630 is located within the air duct cavity 510. In this way, the driving member 630 is located outside the cooking cavity 121 and the air duct cavity 510 and is not easily affected by steam and oil smoke.

[0145] Exemplarily, the driving member 630 may be a motor, an electromagnetic lock, or an electric cylinder.

[0146] Among them, the first seal 640 is connected to the drive shaft, and at least part of the first seal 640 is located in the protective cavity 611. The drive member 630 drives the first seal 640 to move closer to or away from the air duct assembly 500 to make the protective cavity 611 connected or disconnected with the cooking cavity 121.

[0147] In some embodiments of the present application, the inner pot 120 is configured with a third opening that communicates with the cooking cavity 121. The protective member 610 is connected to the outer wall of the inner pot 120, and the first opening 612 is opposite and communicates with the third opening. This eliminates the need for additional pipes for connection, resulting in a simple structure and low cost.

[0148] Illustratively, the third opening may be a circular hole, a rectangular hole, or an irregular hole.

[0149] It should be noted that the third opening is spaced apart from the communicating pipe.

[0150] Figure 10 This is a schematic structural diagram of the first sealing member and the second sealing member in the steam oven provided in an embodiment of the present application.

[0151] See also Figures 5 to 10 As shown, in some embodiments of the present application, the first sealing member 640 includes a first connecting portion 641 and a second connecting portion 642 connected to each other. The first connecting portion 641 can be used to connect to the driving member 630, and the second connecting portion 642 can be used to seal the first opening 612.

[0152] Specifically, the first connection portion 641 and the second connection portion 642 can be integrally provided, which is beneficial to improving installation efficiency.

[0153] Alternatively, the first connection portion 641 and the second connection portion 642 may be separately processed and then assembled.

[0154] In some embodiments, one end of the first connection portion 641 facing away from the second connection portion 642 is connected to the driving member 630 .

[0155] In some embodiments, the first connecting portion 641 is inserted into the first opening 612 and the third opening. The second connecting portion 642 is located within the cooking cavity 121. The cooking cavity 121 has a relatively large space. This allows the second connecting portion 642 to be larger, thereby increasing the contact area during sealing and improving the sealing effect.

[0156] In some embodiments, the orthographic projection of the inner wall of the third opening toward the plane where the first end surface is located is located within the first end surface, wherein the first end surface is the end surface of the second connecting portion 642 toward the first connecting portion 641 .

[0157] That is, the first connection portion 641 is smaller than the second connection portion 642, so that the first connection portion 641 can be smoothly inserted into the protective cavity 611, the first opening 612 and the third opening. The second connection portion 642 is larger, so that the third opening can be smoothly sealed.

[0158] During use, the driving member 630 drives the second connecting portion 642 via the first connecting portion 641 to abut or disengage the inner wall of the inner pot 120, thereby connecting or disconnecting the protective cavity 611 from the cooking cavity 121. It is understood that the structure of the first sealing member 640 in the humidity detection assembly 600 provided in this embodiment is relatively simple, and its reliability is relatively high.

[0159] During steam cooking, the driver 630 drives the second connecting portion 642 away from the air duct cavity 510 via the first connecting portion 641. The second connecting portion 642 disengages from the inner wall of the inner pot 120, opening the third opening. This opens the protective cavity 611 and connects it to the cooking cavity 121. Air from the cooking cavity 121 enters the protective cavity 611 through the third opening and the first opening 612. The humidity sensor 620 detects the humidity in the cooking cavity 121. Furthermore, the air flows through the air duct cavity 510 to the outside of the steam oven.

[0160] During baking and cooking, the humidity sensor 620 does not need to detect the humidity of the cooking cavity 121. The driving member 630 drives the second connecting part 642 to move toward the air duct cavity 510 through the first connecting part 641. The second connecting part 642 abuts against the inner wall of the inner pot 120 to close the third opening. The protective cavity 611 and the cooking cavity 121 are not connected, and the air in the cooking cavity 121 cannot enter the protective cavity 611.

[0161] See also Figure 9As shown, in some embodiments of the present application, the orthographic projection of the inner wall of the third opening toward the plane where the first end face is located is circular, and the first end face is circular. It is understandable that when the humidity detection assembly 600 has installation errors or rotates during use, the second connecting portion 642 can still effectively seal the third opening.

[0162] In some embodiments, the second connection portion 642 may be in a circular shape.

[0163] In some embodiments, the protective member 610 may be in a tubular shape, and the protective cavity 611 may be in a cylindrical shape.

[0164] In some embodiments, axes of the protective member 610 , the protective cavity 611 , the third opening, and the first opening 612 are collinear.

[0165] In some embodiments, the moving direction of the drive shaft is consistent with the axial direction of the protective member 610 .

[0166] Specifically, when the humidity detection assembly 600 is located at the top of the inner container 120, the driving shaft can move along the height direction of the steam oven.

[0167] In other embodiments, the second connecting portion 642 may be in the shape of a circular pancake. The protective cavity 611 may be in the shape of a truncated cone. The dimension of the protective cavity 611 on the side closest to the inner liner 120 is smaller than the dimension of the side facing away from the inner liner 120. The dimension of the second connecting portion 642 is between the dimensions of the two ends of the protective cavity 611. The first connecting portion 641 and the second connecting portion 642 are located within the protective cavity 611.

[0168] During use, the driving member 630 drives the second connecting portion 642 through the first connecting portion 641 to abut or disengage from the inner wall of the protective member 610 , so that the protective cavity 611 is connected or disconnected from the cooking cavity 121 .

[0169] During steam cooking, the driver 630 drives the second connection portion 642 toward the air duct cavity 510 via the first connection portion 641. The second connection portion 642 disengages from the inner wall of the protective member 610, opening the third opening. This opens the protective cavity 611 and connects it to the cooking cavity 121. Air from the cooking cavity 121 enters the protective cavity 611 through the third opening and the first opening 612. The humidity sensor 620 detects the humidity in the cooking cavity 121. Furthermore, the air flows through the air duct cavity 510 to the outside of the steam oven.

[0170] During baking and cooking, the humidity sensor 620 does not need to detect the humidity of the cooking cavity 121. The driving member 630 drives the second connecting part 642 to move away from the air duct cavity 510 through the first connecting part 641. The second connecting part 642 abuts against the inner wall of the protective member 610 to close the third opening. The protective cavity 611 and the cooking cavity 121 are not connected, and the air in the cooking cavity 121 cannot enter the protective cavity 611.

[0171] In some embodiments of the present application, at least part of the protective member 610 is located in the air duct cavity 510, and the second opening 613 is located in the air duct cavity 510. In this way, no additional pipes are required for connection, and the structure is simple and the cost is low.

[0172] See also Figures 5 to 10 As shown, some embodiments of the present application further include a second seal 650 , which is connected to the driving member 630 and the first seal 640 , and is located on the side of the protective member 610 facing away from the inner liner 120 .

[0173] The driving member 630 drives the second sealing member 650 to move relative to the protective member 610, thereby connecting or disconnecting the protective cavity 611 from the air duct cavity 510. Thus, when in steam mode, the second sealing member 650 disconnects the protective cavity 611 from the air duct cavity 510, preventing steam in the cooking cavity 121 from entering the air duct cavity 510 through the protective cavity 611 and causing heat loss.

[0174] In some embodiments of the present application, the humidity sensor 620 is connected to the second sealing member 650. In this way, the humidity sensor 620 can be moved under the action of the driving member 630, so that when no measurement is needed, it can be kept at a greater distance from the inner liner 120, thereby reducing the impact of the temperature of the inner liner 120 on the humidity sensor 620.

[0175] Specifically, during steam cooking, the driver 630 drives the humidity sensor 620 away from the air duct cavity 510 via the first connecting portion 641 and the second connecting portion 642. The second connecting portion 642 disengages from the inner wall of the inner pot 120, opening the third opening. This allows the protective cavity 611 to communicate with the cooking cavity 121. Air from the cooking cavity 121 enters the protective cavity 611 through the third opening and the first opening 612. The humidity sensor 620 detects the humidity in the cooking cavity 121. Furthermore, the air flows through the air duct cavity 510 to the exterior of the steam oven.

[0176] During baking and cooking, the humidity sensor 620 does not need to detect the humidity of the cooking cavity 121. The driving member 630 drives the humidity sensor 620 toward the air duct cavity 510 through the first connecting part 641 and the second connecting part 642. The second connecting part 642 abuts against the inner wall of the inner pot 120 to close the third opening. The protective cavity 611 and the cooking cavity 121 are not connected, and the air in the cooking cavity 121 cannot enter the protective cavity 611.

[0177] In some embodiments, the first seal 640 and the second seal 650 may be integrally formed.

[0178] Alternatively, the first sealing member 640 and the second sealing member 650 may be processed separately and then connected.

[0179] In some embodiments, the first sealing member 640 may be made of rubber, such as silicone.

[0180] In some embodiments, the second sealing member 650 may be made of rubber, such as silicone.
