Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a steam oven. Background Art

[0002] An oven is a sealed household appliance used to bake food or dry products. A steam oven is a type of oven. During the use of a steam oven, a large amount of heat is generated inside the box. Because the mainboard assembly of the steam oven is assembled on the back plate of the box, when the mainboard assembly fails, it is usually necessary to remove the mainboard assembly together with the back plate, which increases the workload of maintenance personnel and increases the difficulty of repairing the mainboard assembly. Utility Model Content

[0003] In view of the problem that the mainboard assembly of the existing steam oven is difficult to repair, the present application proposes a steam oven, which has the technical effect of being easy for users to operate and reducing the difficulty of repairing the mainboard assembly.

[0004] A steam oven, comprising:

[0005] Box;

[0006] A mainboard assembly is movably connected to the box, the mainboard assembly comprises a board, a first connection portion and a second connection portion, the first connection portion is connected to the board, the second connection portion is provided at the box, and the mainboard assembly can switch between a first state and a second state relative to the box;

[0007] In the first state, the plate body is connected to the box body, and the first connecting portion and the second connecting portion are separated; in the second state, the first connecting portion and the second connecting portion are connected.

[0008] In one embodiment, the plate body is provided with a portion to be cut, and the portion to be cut is provided at the edge of the plate body. The box body is provided with a mounting portion. In the first state, the portion to be cut is connected to the mounting portion. In the second state, the portion to be cut is disconnected and separated from the mounting portion.

[0009] In one embodiment, the portion to be cut and the mounting portion are integrally formed.

[0010] In one embodiment, the first connecting portion is disposed on at least two sides of the plate body, and the first connecting portion and the second connecting portion are detachably connected.

[0011] In one embodiment, the first connecting portion includes a first sub-portion and a second sub-portion, and the plate body includes two oppositely disposed end portions, and the two end portions are respectively provided with the first sub-portion and the second sub-portion;

[0012] In the second state, the first sub-portion and the second sub-portion are respectively connected to the corresponding second connecting portion.

[0013] In one embodiment, one of the first sub-part and the second sub-part is provided with a first through hole, and the other is protruded relative to the plate body along the extension direction of the plate body, the side wall of the box body is provided with a second through hole, and the second connecting part includes a connecting member and a clamping member, the connecting member and the clamping member are spaced apart from each other on the side wall, and the clamping member is provided with a clamping groove;

[0014] In the second state, the connecting member passes through the first through hole and the second through hole to fix one of the first sub-section and the second sub-section to the side wall, and the other of the first sub-section and the second sub-section is inserted into the slot.

[0015] In one of the embodiments, the mainboard assembly includes a temperature sensor, and the temperature sensor is used to detect the temperature of the board.

[0016] In one of the embodiments, the steam oven further includes an alarm, and the alarm is electrically connected to the mainboard assembly and the temperature sensor.

[0017] In one of the embodiments, the housing includes a back plate, the back plate is provided with a heat dissipation portion and the mainboard assembly, and the heat dissipation portion is located on one side of the mainboard assembly.

[0018] In one of the embodiments, the steam oven further includes a controller, which is electrically connected to the heat dissipation portion and controls opening and closing of the heat dissipation portion.

[0019] When the steam oven is in use, if the board of the mainboard assembly can operate normally, when the mainboard assembly and the housing are assembled together, the mainboard assembly is in a first state relative to the housing. If the board is damaged, the board can be removed from the housing, and the mainboard can be repaired or replaced. The repaired board or the replaced board can be connected to the housing in a second state, for example, the board can be rotated relative to the initial state (such as 180°), so that the first connection part and the second connection part can be connected to connect the board and the housing together. When the board is damaged, after removing the board from the housing, the board that can operate normally is assembled to the housing in the second state, and the first connection part and the second connection part are connected to each other, so that the board and the housing can be connected together. Compared with replacing the components connected to the mainboard assembly together, the above method simplifies the replacement method of the mainboard assembly, and is convenient for users to repair and replace the mainboard assembly.

[0020] The plate body is provided with a portion to be cut, which is arranged at the edge of the plate body, and the box body is provided with a mounting portion. In a first state, the portion to be cut is connected to the mounting portion, and in a second state, the portion to be cut is disconnected and separated from the mounting portion.

[0021] The shape of the portion to be cut can be, but is not limited to, two circular rings connected to each other, or two circular rings connected by a line segment. The number of the portions to be cut provided on the side of the plate can be determined according to actual conditions. In the first state, the plate is connected to the box body through the portions to be cut and the mounting portion connected to each other.

[0022] Exemplarily, the shape of the plate body may be roughly rectangular, and two portions to be cut may be spaced apart on each side of the plate body. In the first state, each portion to be cut is connected to the corresponding mounting portion. When the plate body cannot operate normally, the user can use pliers to cut the portion to be cut to separate the portion to be cut from the mounting portion. Subsequently, the removed plate body can be repaired. If the electronic components on the plate body are repaired successfully, the plate body can be assembled in the second state (for example, rotating the plate body), and when the first connecting portion and the second connecting portion are connected together, the plate body and the box body are connected together. If the electronic components on the plate body cannot be repaired, a new plate body is assembled to the box body in the second state, and at this time, the first connecting portion of the plate body and the second connecting portion on the box body are connected together.

[0023] In this way, when the plate body is damaged, the user can remove the plate body from the box body by cutting the portion to be cut, which is not only convenient for the user to operate, but also speeds up the speed of removing the portion to be cut from the box body.

[0024] The portion to be cut and the mounting portion are integrally formed.

[0025] In other words, the box includes a back plate, on which a mainboard assembly is disposed. When processing the back plate, a laser can be used to cut out the mounting portion, the plate body, and the portion to be cut on the back plate. The mounting portion and the portion to be cut are connected, and the two are made of the same material, while there is a gap between the plate body and the back plate, so that when the mounting portion and the portion to be cut are separated, the plate body and the back plate can also be separated. Because the corresponding electronic components are mounted on the plate body, the electronic components can be repaired by removing the plate body.

[0026] The above arrangement further simplifies the processing method of the part to be cut and the installation part, and can speed up the processing speed.

[0027] At least two sides of the plate body are provided with a first connecting portion, and the first connecting portion and the second connecting portion are detachably connected.

[0028] The first connection parts are provided on two opposite sides of the plate body, or the first connection parts are provided on two adjacent sides of the plate body, or the first connection parts are provided on all three sides of the plate body. Each first connection part is connected to the corresponding second connection part, and the connection between the first connection part and the second connection part can be, but is not limited to, a clamping connection or a threaded connection.

[0029] Thus, the first connection part can be set on the corresponding side of the plate body according to the actual situation, so as to reserve working space for the user to assemble the first connection part and the second connection part together. In addition, the plate body can be repeatedly disassembled and assembled to repeatedly repair the plate body, thereby reducing the maintenance cost.

[0030] The first connecting part includes a first sub-part and a second sub-part, and the plate body includes two oppositely arranged end parts, and the two end parts are respectively provided with the first sub-part and the second sub-part; in the second state, the first sub-part and the second sub-part are respectively connected to the corresponding second connecting part.

[0031] The structures of the first sub-section and the second sub-section may be the same, or may be different. For example, the structures of the first sub-section and the second sub-section are both configured as protrusions with openings, and the first sub-section and the second sub-section are both connected to the box body through second connecting parts with the same structure. Alternatively, the first sub-section is configured as a protrusion with an opening, the second sub-section is configured as a block, some of the second connecting parts are configured as fasteners, and others are configured as slots, so as to connect the first sub-section and the second sub-section with the corresponding second connecting parts.

[0032] When the plate body is in the first state, the number of first connecting parts can be reduced as much as possible without affecting the connection stability between the plate body and the box body, and the structural types that can be constructed of the first sub-part and the second sub-part can be enriched, thereby reducing the difficulty of preparing the first sub-part and the second sub-part.

[0033] Specifically, one of the first sub-section and the second sub-section is provided with a first through hole, and the other is protruded relative to the plate body along the extension direction of the plate body, the side wall of the box body is provided with a second through hole, and the second connecting part includes a connecting piece and a clamping piece, the connecting piece and the clamping piece are spaced apart on the side wall, and the clamping piece is provided with a slot; in the second state, the connecting piece passes through the first through hole and the second through hole to fix one of the first sub-section and the second sub-section to the side wall, and the other of the first sub-section and the second sub-section is inserted into the slot.

[0034] Exemplarily, along the extension direction of the plate body, the first sub-part and the second sub-part extend in opposite directions relative to the plate body, respectively. The first sub-part is provided with a first through hole, while the second sub-part is not provided with the first through hole. Along the extension direction of the plate body, the side wall is provided with a clamping member and a second through hole at intervals.

[0035] When the plate body is in the first state, the first sub-section and the second through hole are spaced apart, and the connecting piece and the clamping piece are also spaced apart. When the plate body is in the second state, the plate body is rotated so that the first through hole of the first sub-section and the second through hole of the side wall are connected, and the first sub-section and the side wall are connected together by the fastener. The connecting piece of the plate body can extend into the clamping piece and clamp with the clamping piece. In this way, the plate body is connected to the side wall in the posture of the second state.

[0036] The mainboard assembly includes a temperature sensor, which is used to detect the temperature of the board.

[0037] The steam oven further includes a display, which is arranged on the box body and can be electrically connected to the temperature sensor. After the steam oven is started, the temperature sensor can detect the temperature of the plate body and feed back the temperature of the plate body to the display of the steam oven. When the temperature of the plate body is higher than the first preset temperature, the steam oven stops running. When the temperature of the plate body is lower than the first preset temperature, the steam oven continues to run.

[0038] In this way, the temperature of the board body can be detected in real time through the temperature sensor, so that the user can shut down or start the steam oven according to the temperature detected by the temperature sensor, so that the electronic components installed on the board body and the various electronic components installed in the box body always operate at a more suitable temperature, which can reduce the probability of these electronic components being easily damaged due to operation in an environment with excessively high temperatures, reduce the probability of repairing the electronic components, and extend the service life of the above-mentioned electronic components.

[0039] In some embodiments, the steam oven further includes an alarm, which is electrically connected to the mainboard assembly and the temperature sensor.

[0040] A component for self-checking may be provided on the mainboard assembly, and the mainboard assembly performs self-checking each time the steam oven is started. If the mainboard assembly fails, an alarm (such as a buzzer) sounds an alarm. When the mainboard assembly self-checking is completed and there is no problem with the mainboard assembly, the temperature sensor starts to operate. If the temperature of the mainboard assembly is higher than a first preset temperature, the alarm sounds an alarm; if the temperature of the mainboard assembly is lower than the first preset temperature, the steam oven operates.

[0041] In this way, using the alarm to remind the user at different operating stages of the steam oven not only improves the intelligence level of the steam oven, but also reduces the probability of the user forgetting to turn off the steam oven in time.

[0042] Each time the oven is started, the oven's mainboard assembly will first perform a self-test. If the mainboard assembly self-test passes, the alarm will not operate. The oven's temperature sensor will start operating and detect the temperature of the mainboard assembly.

[0043] If the mainboard assembly fails and needs to be repaired, the alarm will sound and the steam oven will stop operating. In this case, the user can remove the board of the mainboard assembly from the box, assuming that the mainboard assembly is initially assembled to the box in the first state. When assembling, the user assembles the board that can operate normally to the box in the second state, and connects the first connection part and the second connection part of the mainboard assembly to each other, so that the board and the box can be connected together.

[0044] Compared with replacing the components connected to the motherboard assembly at the same time, the above method simplifies the replacement method of the motherboard assembly, making it easier for users to repair and replace the motherboard assembly. In addition, the use of a temperature sensor to detect the temperature of the motherboard assembly is conducive to the operation of the motherboard assembly at a normal temperature, reducing the probability of damage to the motherboard assembly due to the operating environment.

[0045] In one of the embodiments, after the temperature detected by the temperature sensor is less than the first threshold, if the temperature detected by the temperature sensor is greater than the second threshold, the heat dissipation part of the steam oven is turned on, otherwise, the heat dissipation part is turned off.

[0046] The steam oven further comprises a controller, which is electrically connected to the heat dissipation part, and the heat dissipation part can be arranged on the box body.

[0047] During the operation of the steam oven, after the mainboard assembly passes the self-test, the temperature sensor starts to operate and detects the temperature of the mainboard assembly. When the temperature of the mainboard assembly is lower than the first threshold and higher than the second threshold, the alarm does not operate, the controller controls the heat dissipation unit to operate, and the heat dissipation unit can supply the heat inside the box to flow outside the box. When the temperature of the mainboard assembly is lower than the first threshold and lower than the second threshold, the alarm does not operate, the heat dissipation unit does not operate, and the heat inside the box cannot flow outside the box through the heat dissipation unit.

[0048] In this way, the opening and closing of the heat dissipation part is controlled by the controller to optimize the heat dissipation effect and reduce energy consumption, so that the temperature inside the box can be within a more suitable range, thereby providing a suitable operating environment for the motherboard components in the box, thereby extending the service life of the motherboard components.

[0061] Please refer to Figures 1 to 4. The present application provides a steam oven 100. The steam oven 100 includes a housing 10 and a mainboard assembly 20. The mainboard assembly 20 is movably connected to the housing 10, and includes a plate 21, a first connection portion 22, and a second connection portion 23. The first connection portion 22 is connected to the plate 21, and the second connection portion 23 is provided on the housing 10. The mainboard assembly 20 can switch between a first state and a second state relative to the housing 10; in the first state, the plate 21 is connected to the housing 10, and the first connection portion 22 and the second connection portion 23 are separated; in the second state, the first connection portion 22 and the second connection portion 23 are connected.

[0062] The box 10 is used to carry the mainboard assembly 20, the heating element, the display and other components. The board 21 of the mainboard assembly 20 is provided with electronic components and is electrically connected to the heating element. The first connecting portion 22 and the second connecting portion 23 are mutually matched components.

[0063] When the board body 21 of the mainboard assembly 20 can operate normally, when the mainboard assembly 20 and the housing 10 are assembled together, the mainboard assembly 20 is in a first state relative to the housing 10. When the board body 21 is damaged, the board body 21 can be removed from the housing 10 and the mainboard can be repaired or replaced. The repaired board body 21 or the replaced board body 21 can be connected to the housing 10 in a second state, for example, the board body 21 can be rotated relative to the initial state (such as rotating 180°), so that the first connection portion 22 and the second connection portion 23 can be connected to connect the board body 21 and the housing 10 together.

[0064] In summary, when the board 21 is damaged, the board 21 can be removed from the box 10, and the board 21 that can operate normally can be assembled in the second state to the box 10, and the first connection portion 22 and the second connection portion 23 are connected to each other, so that the board 21 and the box 10 can be connected together. Compared with replacing the components connected to the mainboard assembly 20 at the same time, the above method simplifies the replacement method of the mainboard assembly 20, and is convenient for users to repair and replace the mainboard assembly 20.

[0065] Further, as shown in Figure 3, in some embodiments, the plate body 21 is provided with a portion to be cut 211, and the portion to be cut 211 is provided at the edge of the plate body 21, and the box body 10 is provided with an installation portion. In a first state, the portion to be cut 211 is connected to the installation portion, and in a second state, the portion to be cut 211 is disconnected and separated from the installation portion.

[0066] The shape of the to-be-cut portion 211 can be, but is not limited to, two circular rings connected to each other, or two circular rings connected by a line segment. The number of the to-be-cut portions 211 provided on the side of the plate body 21 can be determined according to actual conditions. In the first state, the plate body 21 is connected to the box body 10 through the to-be-cut portions 211 and the mounting portion connected to each other.

[0067] Exemplarily, the shape of the plate body 21 may be roughly rectangular, and two to-be-cut portions 211 may be spaced apart on each side of the plate body 21. In the first state, each to-be-cut portion 211 is connected to the corresponding mounting portion. When the plate body 21 cannot operate normally, the user can use pliers to cut the to-be-cut portion 211 to separate the to-be-cut portion 211 from the mounting portion. Subsequently, the removed plate body 21 can be repaired. If the electronic components on the plate body 21 are repaired successfully, the plate body 21 can be assembled in the second state (for example, rotating the plate body 21), and when the first connection portion 22 and the second connection portion 23 are connected together, the plate body 21 and the box body 10 are connected together. If the electronic components on the plate body 21 cannot be repaired, a new plate body 21 is assembled to the box body 10 in the second state, at which time the first connection portion 22 of the plate body 21 and the second connection portion 23 on the box body 10 are connected together.

[0068] In this way, when the plate body 21 is damaged, the user can remove the plate body 21 from the box body 10 by cutting the portion to be cut 211 , which is not only convenient for the user to operate, but also speeds up the removal of the portion to be cut 211 from the box body 10 .

[0069] Furthermore, the portion to be cut 211 and the mounting portion are integrally formed.

[0070] In other words, the box body 10 includes a back plate 12, on which a main board assembly 20 is disposed. When processing the back plate 12, a mounting portion, a plate body 21, and a portion to be cut 211 can be cut out on the back plate 12 by laser. The mounting portion and the portion to be cut 211 are connected, and the two are made of the same material, and there is a gap between the plate body 21 and the back plate 12, so that when the mounting portion and the portion to be cut 211 are separated, the plate body 21 and the back plate 12 can also be separated. Because corresponding electronic components are mounted on the plate body 21, the electronic components can be repaired by removing the plate body 21.

[0071] The above arrangement further simplifies the processing method of the portion to be cut 211 and the installation portion, thereby speeding up the processing.

[0072] As shown in FIG. 3 , in some embodiments, at least two sides of the plate body 21 are provided with a first connection portion 22 , and the first connection portion 22 and the second connection portion 23 are detachably connected.

[0073] The first connection parts 22 are provided on two opposite sides of the plate body 21, or the first connection parts 22 are provided on two adjacent sides of the plate body 21, or the first connection parts 22 are provided on three sides of the plate body 21. Each first connection part 22 is connected to the corresponding second connection part 23, and the connection between the first connection part 22 and the second connection part 23 can be, but is not limited to, a clamping connection or a threaded connection.

[0074] In this way, the first connection part 22 can be set on the corresponding side of the plate body 21 according to actual conditions, thereby reserving a working space for the user to assemble the first connection part 22 and the second connection part 23. In addition, the plate body 21 can be repeatedly disassembled and assembled to repeatedly repair the plate body 21, thereby reducing the maintenance cost.

[0075] In some embodiments, as shown in Figures 3 and 4, the first connecting portion 22 includes a first sub-portion 221 and a second sub-portion 222, and the plate body 21 includes two oppositely arranged end portions, and the two end portions are respectively provided with the first sub-portion 221 and the second sub-portion 222; in the second state, the first sub-portion 221 and the second sub-portion 222 are respectively connected to the corresponding second connecting portion 23.

[0076] The structures of the first sub-section 221 and the second sub-section 222 may be the same or different. For example, the structure of the first sub-section 221 and the structure of the second sub-section 222 are both configured as protrusions with openings, and the first sub-section 221 and the second sub-section 222 are both connected to the box body 10 through the second connecting section 23 with the same structure. Alternatively, the first sub-section 221 is configured as a protrusion with an opening, the second sub-section 222 is configured as a block, some of the second connecting sections 23 are configured as fasteners, and others are configured as slots, so as to connect the first sub-section 221 and the second sub-section 222 with the corresponding second connecting section 23.

[0077] When the plate body 21 is in the first state, the number of first connecting parts 22 can be reduced as much as possible without affecting the connection stability between the plate body 21 and the box body 10, and the structural types that can be constructed of the first sub-part 221 and the second sub-part 222 can be enriched, thereby reducing the difficulty of preparing the first sub-part 221 and the second sub-part 222.

[0078] Specifically, please refer to Figure 3. In some embodiments, one of the first sub-section 221 and the second sub-section 222 is provided with a first through hole 24, and the other is protruded relative to the plate body 21 along the extension direction of the plate body 21, and the side wall of the box body 10 is provided with a second through hole 11. The second connecting part 23 includes a connecting piece and a snap-on piece 231, and the connecting piece and the snap-on piece 231 are spaced apart on the side wall, and the snap-on piece 231 is provided with a slot; in the second state, the connecting piece passes through the first through hole 24 and the second through hole 11 to fix one of the first sub-section 221 and the second sub-section 222 to the side wall, and the other of the first sub-section 221 and the second sub-section 222 is inserted into the slot.

[0079] Exemplarily, along the extension direction of the plate body 21, the first sub-portion 221 and the second sub-portion 222 extend in opposite directions relative to the plate body 21. The first sub-portion 221 is provided with a first through hole 24, while the second sub-portion 222 is not provided with a first through hole 24. Along the extension direction of the plate body 21, the side wall is provided with a clamping member 231 and a second through hole 11 at intervals.

[0080] When the plate body 21 is in the first state, the first sub-section 221 and the second through hole 11 are spaced apart, and the connecting piece and the clamping piece 231 are also spaced apart. When the plate body 21 is in the second state, the plate body 21 is rotated so that the first through hole 24 of the first sub-section 221 is connected to the second through hole 11 of the side wall, and the first sub-section 221 and the side wall are connected together by the fastener. The connecting piece of the plate body 21 can extend into the clamping piece 231 and clamp with the clamping piece 231. In this way, the plate body 21 is connected to the side wall in the posture of the second state.

[0081] It should be noted that, in the example shown in Fig. 4, the number of the first sub-section 221 is one, and the number of the second sub-section 222 is two. In other embodiments, the number of the first sub-section 221 and the second sub-section 222 can be increased or decreased according to actual conditions.

[0082] The above arrangement not only simplifies the structure of the first sub-section 221 and the second sub-section 222 , but also reduces the difficulty for the user to connect the first sub-section 221 and the second sub-section 222 with corresponding components, thus facilitating the user's operation.

[0083] In some embodiments, the mainboard assembly 20 includes a temperature sensor (not shown in the figures), which is used to detect the temperature of the board body 21 .

[0084] The steam oven 100 further includes a display, which is disposed on the housing 10 and can be electrically connected to the temperature sensor. After the steam oven 100 is started, the temperature sensor can detect the temperature of the plate 21 and feed back the temperature of the plate 21 to the display of the steam oven 100. When the temperature of the plate 21 is higher than the first preset temperature value, the steam oven 100 stops operating. When the temperature of the plate 21 is lower than the first preset temperature value, the steam oven 100 continues operating.

[0085] In this way, the temperature of the plate body 21 can be detected in real time by the temperature sensor, so that the user can shut down or start the steam oven 100 according to the temperature detected by the temperature sensor, so that the electronic components installed on the plate body 21 and the various electronic components installed in the box body 10 always operate at a more suitable temperature, which can reduce the probability of these electronic components being easily damaged due to operation in an environment with too high a temperature, reduce the probability of repairing the electronic components, and extend the service life of the above-mentioned electronic components.

[0086] In some embodiments, the steam oven 100 further includes an alarm (not shown in the figure), which is electrically connected to the mainboard assembly 20 and the temperature sensor.

[0087] The mainboard assembly 20 may be provided with a component for self-checking. Each time the steam oven 100 is started, the mainboard assembly 20 will perform a self-check. If the mainboard assembly 20 fails, an alarm (such as a buzzer) will sound an alarm. When the mainboard assembly 20 self-checks and there is no problem with the mainboard assembly 20, the temperature sensor starts to operate. If the temperature of the mainboard assembly 20 is higher than the first preset temperature value, the alarm will sound an alarm; if the temperature of the mainboard assembly 20 is lower than the first preset temperature value, the steam oven 100 will operate.

[0088] In this way, the alarm is used to remind the user at different operation stages of the steam oven 100, which not only improves the intelligence level of the steam oven 100, but also reduces the probability that the user forgets to turn off the steam oven 100 in time.

[0089] As shown in FIG. 1 and FIG. 2 , in some embodiments, the housing 10 includes a back plate 12 , and the back plate 12 is provided with a heat dissipation portion 121 and a mainboard assembly 20 , and the heat dissipation portion 121 is located on one side of the mainboard assembly 20 .

[0090] The box body 10 may also include a bottom plate, a top plate 13, two side plates 14 and a display panel 15, on which a display is provided. The side plates 14 are provided with side plate 14 buckles, and the side plates 14 and the bottom plate are connected by the side plate 14 buckles and can also be fixed by screws. The back plate 12 is provided with a back plate 12 buckle, and the back plate 12 and the two side plates 14 are also connected together by the back plate 12 buckle and fixed by screws. The top plate 13 can be connected to the side plates 14 and the back plate 12 by screws.

[0091] The heat dissipation portion 121 provided on the back plate 12 may be, but is not limited to, a heat dissipation hole, which is provided near the mainboard assembly 20 to allow the heat inside the box 10 to flow outside the box 10. A layer of microporous filter may be covered on the heat dissipation hole to prevent dust, water vapor, etc. from entering the steam oven 100 through the heat dissipation hole. In this embodiment, three heat dissipation holes are provided, and each heat dissipation hole can be switched between an open state and a closed state. The number and location of the heat dissipation holes can be adjusted according to actual conditions.

[0092] Such an arrangement can accelerate the speed at which the heat near the motherboard assembly 20 flows to the outside of the housing 10 , thereby improving the protection effect of the motherboard assembly 20 .

[0093] In some embodiments, the steam oven 100 further includes a controller (not shown in the figure), which is electrically connected to the heat dissipation portion 121 and controls the opening and closing of the heat dissipation portion 121 .

[0094] During the operation of the steam oven 100, each component inside the cabinet 10 can generate heat. When the generated heat is lower than the first preset temperature value, the alarm stops running. The steam oven 100 continues to run, and when the generated temperature is higher than the second preset temperature value, the heat dissipation unit 121 starts running under the control of the controller, and the heat in the cabinet 10 can flow to the outside of the cabinet 10 through the heat dissipation unit 121. When the generated temperature is lower than the second preset temperature value, the heat dissipation unit 121 is closed under the control of the controller, and the heat in the cabinet 10 cannot flow to the outside of the cabinet 10 through the heat dissipation unit 121.

[0095] It should be noted that the controller can control the opening degree of the heat dissipation portion 121 according to the temperature level in the box 10 to adjust the temperature in the box 10 .

[0096] In this way, the opening and closing of the heat dissipation part 121 is controlled by the controller to optimize the heat dissipation effect and reduce energy consumption, so that the temperature inside the box 10 can be within a more suitable range, thereby providing a suitable operating environment for the motherboard assembly 20 in the box 10, thereby extending the service life of the motherboard assembly 20.

[0097] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0098] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
