[0047] Due to problems such as improper production and assembly methods and improper use and operation of existing steam ovens, air leakage is extremely likely to occur, which requires a large amount of resources for inspection and treatment, and even affects production plans and other adverse phenomena. The root cause is that the compression allowance between the door body and the door seal is insufficient and does not reach the specified compression allowance.

[0048] The compression allowance refers to the extra space reserved during the design and manufacturing processes to adapt to various changes. When the compression allowance is insufficient, the sealing performance between the door body and the door seal is poor, and the sealing effect of the steam oven is poor. In actual operation, the compression allowance often cannot be directly measured. In related technologies, whether the specified compression allowance is reached is generally indirectly judged by air leakage or measuring the door pulling force, and the accuracy of the judgment is low, which cannot well ensure the sealing performance of the steam oven, and the steam oven is prone to air leakage.

[0049] In view of the above technical problems, the embodiments of the present application provide a door body device and a cooking device. The door body device includes a magnetic switch assembly. The front door and the rear door are compressed against each other under an external force, so that the magnetic member and the sensing member approach each other. In this way, the present application can ensure that the compression allowance meets the design requirements according to the magnetic member being within the sensing range of the sensing member and the compression allowance of the door body device on the box body meeting the preset compression allowance, thereby ensuring that the cooking device is in a sealed state to the greatest extent, improving the sealing performance of the cooking device, and avoiding problems such as air leakage of the cooking device. In addition, the sensing member of the present application completes the action of circuit disconnection or closing, which is a non-contact trigger, helping to avoid trigger failure caused by the sensing member not being in place due to processing manufacturing and installation errors, and further ensuring the detection accuracy.

[0050] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals denote the same or similar components or components with the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of the present application. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0051] Referring to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a cooking device 200, including a box body 210 and a door device 100; the box body 210 has a box opening 212, and the door device 100 is movably connected to the box body 210.

[0052] In the embodiment of the present application, the type of the cooking device 200 is not limited. Exemplarily, the cooking device 200 in this embodiment may be an oven, a steam box, a steam oven, a steam oven with microwave function, etc. In this embodiment, the cooking device 200 is mainly taken as a steam box for illustration.

[0053] The working principle of the steam box is as follows: the steam box uses the heat generated after the electric heating element is energized to heat water to generate steam, so as to achieve the purpose of cooking food. The electric heating element may be an internal evaporation pan or an external evaporator. This embodiment does not limit this.

[0054] In the embodiment of the present application, the movable connection manner between the door device 100 and the box body 210 is not limited. Exemplarily, the door device 100 and the box body 210 may be rotatably connected. For example, the door device 100 may be flipped open; or, the door device 100 may be opened horizontally; Exemplarily, the door device 100 and the box body 210 may also be hinged. This embodiment does not limit this.

[0055] Specifically, in the embodiment of the present application, referring to Figure 1 and Figure 2 As shown, the box body 210 may include an outer shell 213, an inner container 211 is provided in the outer shell 213, and a water tank 220 and a heating plate 240 are provided in the inner container 211. It should be noted that the inner container 211 is also the cooking cavity of the cooking device 200, and the inner container 211 is used for cooking food. A sealing strip may be provided at the edge of the box opening 212 to ensure the sealing of the cooking cavity after the door is closed.

[0056] In this way, when the box opening 212 is closed, an external force is applied to the door body device 100. Under the action of the external force, the door body device 100 slides towards the side close to the inner liner 211. The door body device 100 compresses the sealing strip 250. When the sealing strip 250 is continuously squeezed, a reverse acting force will be generated, causing the door body device 100 to slide towards the side away from the inner liner 211 while compressing the door sealing strip. Among them, in order to ensure the good sealing performance of the cooking device 200 and avoid the problem of air leakage of the cooking device 200, the compression amount of the door body device 100 on the sealing strip 250 generally needs to reach the specified compression allowance, so as to avoid the frequent occurrence of air leakage of the cooking device 200 due to insufficient compression allowance.

[0057] Referring to Figures 3 to 6 As shown, an embodiment of the present application provides a door body device 100, which may include a rear door 110 and a front door 120. The front door 120 is disposed opposite to the rear door 110 and is movably connected. The rear door 110 is movably connected to the box body 210. The front door 120 is located on the side of the rear door 110 away from the box body 210. The front door 120 and the rear door 110 enclose an installation cavity 130 of the cooking device 200.

[0058] In the embodiment of the present application, the rear door 110 refers to the door panel on the side close to the inner liner 211 when the door body device 100 is installed on the box body 210; the front door 120 refers to the door panel on the side away from the inner liner 211 when the door body device 100 is installed on the box body 210.

[0059] In the embodiment of the present application, the front door 120 is disposed opposite to the rear door 110 and is movably connected. Among them, the movable connection manner of the front door 120 and the rear door 110 is not limited. Exemplarily, the front door 120 and the rear door 110 can be snap-connected; or, the front door 120 and the rear door 110 can be rotatably connected; or, the front door 120 and the rear door 110 can be slidably connected. This embodiment does not limit this.

[0060] In the embodiment of the present application, referring to Figures 3 to 6 As shown, a magnetic switch assembly 140 may be provided in the installation cavity 130. In this way, the installation cavity 130 helps to install and protect the magnetic switch assembly 140, which is beneficial to ensuring the normal operation of the magnetic switch assembly 140 and avoiding the risk of damage to the magnetic switch assembly 140 by external impurities or water stains.

[0061] The magnetic switch assembly 140 may include a magnetic member 141 and an induction member 142 disposed opposite to each other. Among them, the installation positions of the magnetic member 141 and the induction member 142 are not limited. Exemplarily, the magnetic member 141 may be disposed on the rear door 110, and the induction member 142 may be disposed on the front door 120; or, the magnetic member 141 may be disposed on the front door 120, and the induction member 142 may be disposed on the rear door 110.

[0062] In this embodiment, the description is mainly given by taking the magnetic member 141 disposed on the rear door 110 and the sensing member 142 disposed on the front door 120 as an example.

[0063] It should be noted that the magnetic member 141 and the sensing member 142 are oppositely arranged. In this way, the magnetic member 141 and the sensing member 142 are arranged face to face, and the magnetic field of the magnetic member 141 can directly act on the sensing member 142, thereby controlling the on-off of the circuit. Moreover, this arrangement is conducive to improving the sensitivity and response speed of the sensing member 142, ensuring the maximization of the magnetic field efficiency, and helping to reduce energy loss and signal attenuation.

[0064] In this way, when closing the box opening 212, an external force is applied to the front door 120. Under the action of the external force, the front door 120 slides backward toward the rear door 110. The rear door 110 compresses the sealing strip 250. When the sealing strip 250 is continuously squeezed, a reverse acting force will be generated, causing the rear door 110 to slide toward the front door 120 while compressing the sealing strip 250. In this way, the front door 120 and the rear door 110 are compressed against each other under the action of the external force, the distance between the front door 120 and the rear door 110 is reduced, and further the distance between the magnetic member 141 and the sensing member 142 is reduced. When the magnetic member 141 is within the sensing range of the sensing member 142 and the compression allowance of the door body device 100 on the box body 210 meets the preset compression allowance, a sealed state of the door body device 100 on the box body 210 is formed.

[0065] It should be noted that the preset compression allowance is a fixed value set in advance, and the preset compression allowance is the compression allowance of the rear door 110 on the sealing strip 250 and the compression allowance that ensures the good sealing state of the cooking device 200. Among them, the preset compression allowance corresponds to the sliding amount of the magnetic member 141 relative to the sensing member 142. This is because, assuming that the preset compression allowance is larger, the compression amount of the rear door 110 on the sealing strip 250 is larger, the reverse acting force of the sealing strip 250 on the rear door 110 is larger, the sliding amount of the rear door 110 relative to the front door 120 is larger, and the sliding amount of the magnetic member 141 relative to the sensing member 142 is larger. Therefore, the door body device 100 has a preset sliding amount corresponding to when the preset compression allowance is met, so that it can be judged whether the compression allowance of the rear door 110 on the sealing strip 250 meets the preset compression allowance according to the preset sliding amount, and further judge whether the cooking device 200 is sealed.

[0066] For example: Assume that the preset slip amount when meeting the preset compression margin is 0.5 mm. In the actual process, if the slip amount of the magnetic member 141 relative to the sensing member 142 is 0.3 mm, the slip amount is less than the preset slip amount, indicating that the compression margin of the rear door 110 on the sealing strip 250 is insufficient, and the compression amount of the rear door 110 on the sealing strip 250 is small, which may cause the cooking device 200 not to achieve a good sealing effect; if the slip amount of the magnetic member 141 relative to the sensing member 142 is 0.5 mm, the compression margin is equal to the preset compression margin, the compression amount of the rear door 110 on the sealing strip 250 meets the preset compression margin, and the cooking device 200 can achieve a good sealing effect.

[0067] It should be noted that the magnetic member 141 being within the sensing range of the sensing member 142 means: Referring to Figure 4 and Figure 6 As shown, the sensing member 142 includes a first sensing member 1421 and a second sensing member 1422. The first sensing member 1421 and the second sensing member 1422 are switch elements composed of elastic reed pieces. When the magnetic member 141 is within the sensing range of the sensing member 142, the first sensing member 1421 and the second sensing member 1422 will be magnetized and attracted to each other, and the circuit is turned on; when the magnetic member 141 is outside the sensing range of the sensing member 142, the first sensing member 1421 and the second sensing member 1422 are separated, and the circuit is turned off.

[0068] Exemplarily, the magnetic member 141 in this embodiment can be a magnet.

[0069] Exemplarily, Figure 3 and Figure 4 are schematic structural diagrams of the first sensing member 1421 and the second sensing member 1422 not being closed when the door body device is in the unclosed state. Figure 5 and Figure 6 are schematic structural diagrams of the first sensing member 1421 and the second sensing member 1422 being closed when the door body device is in the closed state.

[0070] In this way, when the magnetic member 141 is within the sensing range of the sensing member 142 and the sensing member 142 is closed to form a path, and the compression margin of the door body device 100 on the cabinet 210 meets the preset compression margin (that is, the slip amount of the magnetic member 141 relative to the sensing member 142 reaches the preset slip amount), it can be determined that the compression margin meets the design requirements, and further it can be determined that the cooking device 200 is in a sealed state, improving the sealing performance of the cooking device 200 and helping to avoid problems such as air leakage in the cooking device 200.

[0071] In an implementable embodiment, referring to Figure 3 and Figure 5As shown, the magnetic member 141 can be disposed on the rear door 110. The number of magnetic members 141 can include a plurality, and the plurality of magnetic members 141 are arranged at intervals; the sensing member 142 can be disposed on the front door 120. The number of sensing members 142 can include a plurality, and the plurality of sensing members 142 are arranged at intervals; along the direction from the rear door 110 to the front door 120, the plurality of magnetic members 141 and the plurality of sensing members 142 correspond one by one.

[0072] In the embodiment of the present application, the number of the magnetic member 141 and the sensing member 142 is not limited. Exemplarily, the number of the magnetic members 141 can be two, three or more; the number of the sensing members 142 can be two, three or more. In this embodiment, with reference to Figure 4 and Figure 6 As shown, mainly taking the number of the magnetic members 141 being two and the number of the sensing members 142 being two as an example for illustration.

[0073] In the embodiment of the present application, the arrangement manner of the magnetic member 141 on the rear door 110 is not limited. Exemplarily, the magnetic members 141 can be arranged at intervals along the height direction of the rear door 110, or the magnetic members 141 can be arranged at intervals along the length direction of the rear door 110; or the magnetic members 141 can be arranged at intervals along the width direction of the rear door 110. Similarly, the arrangement manner of the sensing member 142 on the front door 120 is not limited. Exemplarily, the sensing members 142 can be arranged at intervals along the height direction of the front door 120; or the sensing members 142 can be arranged at intervals along the length direction of the front door 120; or the sensing members 142 can be arranged at intervals along the width direction of the front door 120.

[0074] In this embodiment, with reference to Figure 3 and Figure 5 As shown, mainly taking the magnetic members 141 being arranged at intervals along the height direction of the rear door 110 and the sensing members 142 being arranged at intervals along the height direction of the front door 120 as an example for illustration. In this way, it is beneficial to adapt to the structure of the door body device 100 of the present application, the distribution of the magnetic switch assembly 140 is more uniform, and the sensing range of the sensing member 142 is also more uniform, thereby helping to further accurately detect the slip amount of the magnetic member 141 relative to the sensing member 142.

[0075] In a feasible implementation manner, with reference to Figure 3 and Figure 5 As shown, the number of the magnetic members 141 can include two. Along the height direction of the rear door 110, one of the magnetic members 141 can be disposed near the top of the rear door 110, and the other magnetic member 141 can be disposed near the bottom of the rear door 110.

[0076] The number of the sensing members 142 may include two. Along the height direction of the front door 120, one sensing member 142 may be arranged near the top of the front door 120, and the other sensing member 142 may be arranged near the bottom of the front door 120. One magnetic member 141 is arranged opposite to one sensing member 142, and the other magnetic member 141 is arranged opposite to the other sensing member 142.

[0077] With such an arrangement, it is beneficial to make rational use of the internal space of the installation cavity 130, avoid occupying the middle area of the installation cavity 130, thereby helping to avoid the problem of assembly interference with other structural members inside the installation cavity 130. In addition, it also helps to avoid the normal induction between the magnetic member 141 and the sensing member 142 being affected by other structural members.

[0078] It should be noted that in this embodiment, the assembly methods of the magnetic member 141 and the sensing member 142 include but are not limited to the above-mentioned various methods, and can be specifically set according to actual needs. This embodiment does not make any limitations in this regard.

[0079] In an implementable embodiment, with reference to Figure 3 and Figure 5 as shown, it may further include a first mounting member 150. In this embodiment, the structure of the first mounting member 150 is not limited.

[0080] Exemplarily, with reference to Figure 7 and Figure 8 as shown, in this embodiment, the first mounting member 150 may include at least two first buckles 151 and at least two first limiting pieces 152; at least two first buckles 151 are arranged opposite to each other, and at least two first limiting pieces 152 are arranged opposite to each other. Among them, the first limiting piece 152 is configured to limit the radial movement of the magnetic member 141, and the first buckle 151 is configured to limit the axial movement of the magnetic member 141.

[0081] In the embodiment of the present application, the number of the first buckles 151 and the first limiting pieces 152 is not limited. Exemplarily, the number of the first buckles 151 and the first limiting pieces 152 may be two, three, four or more. In this embodiment, mainly taking the example of including two first buckles 151 and two first limiting pieces 152 for illustration.

[0082] During installation in this way, the magnetic member 141 can be snapped between the two first buckles 151. The two first buckles 151 can limit the axial movement of the magnetic member 141, and the two first limiting pieces 152 can limit the radial movement of the magnetic member 141. The installation is simpler and more convenient, saving time, and can ensure the fixation and limitation of the magnetic member 141, and ensure the installation stability of the magnetic member 141.

[0083] Therefore, the assembly method of this embodiment is not only beneficial to processing and manufacturing, but also can ensure the fixation and limitation of the magnetic part 141, and ensure the installation stability of the magnetic part 141. On the other hand, it is beneficial to expose the magnetic part 141, thereby ensuring that the magnetic field is not blocked and ensuring the induction effect of the induction part 142.

[0084] It should be noted that in this embodiment, the height relationship among the first limiting piece 152, the first buckle 151, and the magnetic part 141 is not limited, and can be specifically set according to actual needs. Among them, the height of the first limiting piece 152 can be lower than the height of the first buckle 151. In this way, on the basis of ensuring the fixation and limitation of the magnetic part 141, it is beneficial to processing and manufacturing, and does not block the magnetic part 141.

[0085] In addition, in this embodiment, the materials of the first limiting piece 152 and the first buckle 151 are not limited. Exemplarily, the first limiting piece 152 and the first buckle 151 can be made of a plastic material with a certain flexibility, which can be conveniently installed and disassembled and has a certain strength.

[0086] In the embodiment of the present application, with reference to Figures 9 to 12 as shown, the door body device 100 may further include a second mounting member 160. The second mounting member 160 has an assembly cavity 162 (which can be referred to Figure 4 and Figure 6 as shown), and the induction part 142 is installed in the assembly cavity 162.

[0087] Exemplarily, the second mounting member 160 in this embodiment may be a card cover. The assembly cavity 162 can wrap the induction part 142, and the assembly cavity 162 can play a role in installing and protecting the induction part 142, which is beneficial to ensuring the normal operation of the induction part 142 and avoiding the influence of the induction part 142 by the external structural parts during assembly.

[0088] Exemplarily, the second mounting member 160 has an opening 163 (which can be referred to Figure 4 and Figure 6 as shown), and the opening 163 faces the magnetic part 141. In this way, it helps to ensure that the induction part 142 quickly senses the magnetic field.

[0089] Exemplarily, with reference to Figure 9 as shown, a viewing window 164 may be opened at the top of the card cover, so that the placement state of the induction part 142 can be observed during installation; in addition, a lead outlet 165 may be opened at the side of the card cover, and the lead outlet 165 reserves a position for the connecting wire 1423 of the induction part.

[0090] In the embodiment of the present application, with reference to Figure 9 and Figure 12As shown, at least four second buckles 1611 and at least two second limiting pieces 1612 can be arranged around the outer periphery of the second mounting member 160.

[0091] In the embodiment of the present application, the numbers of the second buckles 1611 and the second limiting pieces 1612 are not limited. Exemplarily, the number of the second buckles 1611 can be four, five or more, and the number of the second limiting pieces 1612 can be two, three or more.

[0092] In this embodiment, it is mainly described by taking the example of including four second buckles 1611 and two second limiting pieces 1612. Among them, at least four second buckles 1611 are arranged in pairs opposite to each other, and at least two second limiting pieces 1612 are arranged opposite to each other.

[0093] In this embodiment, the distance between the opposite second buckles 1611 can be the width of the card cover plus 1-2 mm, and the distance between the two second limiting pieces 1612 can be the length of the card cover plus 1-2 mm. This embodiment does not limit this. In this way, it is beneficial to the assembly and clamping of the card cover.

[0094] In this way, during installation, the sensing member 142 is placed in the assembly cavity 162, one side of the card cover abuts against one of the second limiting pieces 1612, and the other end of the card cover is pressed, and the whole card cover can be buckled into the four second buckles 1611. Under the joint action of the second buckles 1611 and the second limiting pieces 1612, it helps to ensure the fixation and limitation of the sensing member 142, ensure the installation stability of the sensing member 142, the installation is simpler and more convenient, and it helps to save time.

[0095] In an implementable embodiment, with reference to Figure 3 and Figure 5 As shown, an elastic member 170 can also be included. The elastic member 170 is arranged in the installation cavity 130, and the elastic member 170 is located between two adjacent magnetic switch assemblies 140; the rear door 110 and the front door 120 achieve slow-speed movement through the elastic member 170.

[0096] In the embodiment of the present application, the type of the elastic member 170 is not limited. Exemplarily, the elastic member 170 can be a spring, and the two ends of the spring respectively abut against the front door 120 and the rear door 110; alternatively, the elastic member 170 can also be rubber. Rubber is a common elastic material with good elasticity and flexibility and can quickly return to its original state after being stressed; alternatively, the elastic member 170 can be a structural member with a certain resilience ability. In this embodiment, it is mainly described by taking the elastic member 170 as a spring as an example. In this way, the elastic energy storage and release can be carried out by using the elastic force of the spring itself, and it has the beneficial effects of simple structure and long service life.

[0097] In the embodiments of the present application, the number of elastic members 170 provided is not limited. Exemplarily, the number of elastic members 170 can be one, two, or more. In this embodiment, mainly two elastic members 170 are taken as an example for illustration.

[0098] In the embodiments of the present application, the setting position of the elastic member 170 is not limited. Exemplarily, the two elastic members 170 can be arranged between two adjacent magnetic switch components 140; alternatively, the elastic member 170 can be arranged near the edge position of the installation cavity 130.

[0099] In this embodiment, mainly two elastic members 170 arranged between two adjacent magnetic switch components 140 are taken as an example for illustration. One of the elastic members 170 can be close to one of the magnetic switch components 140, and the other elastic member 170 can be close to the other magnetic switch component 140.

[0100] It should be noted that if the distance between the elastic member 170 and the magnetic switch component 140 is relatively far, when the rear door 110 moves outward relative to the front door 120, the magnetic member 141 cannot move along the same direction towards the sensing member 142 in a timely manner under the drive of the rear door 110, and there is a deviation in the sliding amount between the two. Therefore, in the present application, the elastic member 170 is arranged relatively close to the magnetic switch component 140. When the rear door 110 moves outward relative to the front door 120, the magnetic member 141 can move along the same direction towards the sensing member 142 in a timely manner under the drive of the rear door 110, ensuring the detection accuracy to the greatest extent.

[0101] In an implementable embodiment, with reference to Figure 3 and Figure 5 as shown, it may further include a first limiting member 180. The first limiting member 180 is arranged in the installation cavity 130, and the rear door 110 and the front door 120 are connected through the first limiting member 180; the first limiting member 180 has a limiting cavity 183, and the elastic member 170 is located in the limiting cavity 183.

[0102] In the embodiments of the present application, the structure of the first limiting member 180 is not limited. Exemplarily, in this embodiment, the first limiting member 180 can include a first limiting portion 181 and a second limiting portion 182. The first limiting portion 181 is connected to the rear door 110 (with reference to Figure 13 as shown), and the second limiting portion 182 is connected to the front door 120 (with reference to Figure 14 as shown). The first limiting portion 181 and the second limiting portion 182 are sleeved and can slide relative to each other.

[0103] In this way, the first limiting portion 181 and the second limiting portion 182 can limit the maximum distance that the rear door 110 moves relative to the front door 120, improving the sliding stability and helping to avoid misaligned sliding. Exemplarily, the first limiting portion 181 and the second limiting portion 182 can also be a sliding rail and a rib that are snap-fitted to each other, etc. This embodiment does not limit this.

[0104] In this embodiment, referring to Figure 3 and Figure 5 as shown, mainly taking the first limiting member 180 including a first limiting portion 181 and a second limiting portion 182, the first limiting being a limiting sleeve and the second limiting portion 182 being a limiting sliding sleeve as an example for description, the limiting sleeve and the limiting sliding sleeve are sleeved and can slide relative to each other, and can play a role in connecting the front door 120 and the rear door 110.

[0105] In the embodiment of the present application, referring to Figure 3 and Figure 5 as shown, the door body device 100 can also include a second limiting member 190. The second limiting member 190 is disposed at the connection between the rear door 110 and the front door 120, and the second limiting member 190 is used to limit the minimum distance that the front door 120 moves relative to the rear door 110.

[0106] In the embodiment of the present application, the structure of the second limiting member 190 is not limited. Exemplarily, referring to Figure 3 and Figure 5 as shown, the second limiting member 190 includes a limiting protrusion 191 and a limiting groove 192. The limiting protrusion 191 is disposed on the rear door 110, and the limiting groove 192 is disposed on the front door 120. In this way, the limiting protrusion 191 is engaged in the limiting groove 192, which is beneficial to limiting the sliding amount of the front door 120 and the rear door 110, ensuring that the installation space of the installation cavity 130 is not greatly affected, and helping to avoid the problem of the magnetic member 141 and the sensing member 142 coming into contact.

[0107] It should be noted that the limiting cavity 183 in this embodiment can be formed in the first limiting member 180; or, the limiting cavity 183 can be formed in the second limiting member 190; or, the limiting cavity 183 can be formed in both the first limiting member 180 and the second limiting member 190 at the same time. This embodiment does not limit this.

[0108] It should be noted that in this embodiment, the structures of the first limiting member 180 and the second limiting member 190 include but are not limited to the above-mentioned various structures, and can be specifically set according to actual needs.

[0109] Therefore, the embodiments of the present application provide a door body device and a cooking appliance. The door body device includes a magnetic switch assembly.
