The oven lamp 304 is located in the cooking cavity 201 and connected to the connection hole 202 to illuminate the inside of the cooking cavity 201, so that a user can observe the state of food in the cooking cavity 201 through an observation window provided on the home steam oven 100, and adjust the temperature, heating time, etc. of the home steam oven 100 in time.

The fan 305 is connected to the liner 20, the fan 305 is provided with an air inlet and an air outlet which are communicated with the cooking cavity 201, the fan 305 can suck air or steam in the cooking cavity 201 into the fan 305 from the air inlet, and then the air or steam in the cooking cavity 201 flows and circulates through the air outlet, so that the temperature in the cooking cavity 201 is uniformly distributed, and the domestic steam oven 100 can cook food better.

In order to connect the cooking assembly 30 to the inner container 20, a connection hole 202 needs to be formed in the inner container 20, the cooking assembly 30 is connected to the inner container 20 through a plurality of connection holes 202, a large amount of steam is generated in the cooking cavity 201 when the domestic steam oven 100 cooks, the steam will increase the pressure inside the cooking cavity 201, so that the pressure inside the cooking cavity 201 is higher than the pressure inside the detection cavity 101, and therefore, the steam inside the cooking cavity 201 tends to leak out of the detection cavity 101 under the action of the air pressure difference, and a gap exists when the cooking assembly 30 and the connection hole 202 are connected, and the gap will become a position where the steam leaks out of the cooking cavity 201 to the detection cavity 101.

It should be noted that, the location of the leakage fault of the steam oven 100 includes, but is not limited to, the junction between the cooking assembly 30 and the connecting hole 202, and other opening locations of the liner 20 are also locations where the leakage fault is likely to occur, and the monitoring control assembly 40 of the present utility model may be used for monitoring leakage.

The monitoring control assembly 40 is used for controlling whether leakage occurs at the position where the leakage fault occurs, and controlling the domestic steam oven 100 to send out a leakage alarm message to remind users and maintenance personnel of the leakage fault of the domestic steam oven 100.

In some embodiments, the domestic steam oven 100 further includes a display screen 70 electrically connected to the control device 402 for displaying a steam leakage alarm message, and the maintenance staff can know the position of the steam leakage according to the steam leakage alarm message displayed by the display screen 70, and repair the air leakage fault according to the position of the steam leakage.

Specifically, a humidity sensor 401 is disposed at each connection hole 202, the humidity sensor 401 can detect the humidity value at the connection hole 202, the control device 402 can obtain the humidity value detected by the humidity sensor 401, the control device 402 can compare the obtained humidity value with a preset humidity value, and the tool state of the cooking assembly in the cooking appliance is controlled and whether to send out the steam leakage alarm information is judged according to the comparison result of the humidity value and the preset humidity value.

When the humidity value obtained by the control device 402 is smaller than the preset humidity value, the control device 402 controls the cooking assembly 30 to work normally, and no leakage alarm information is sent. When the humidity value obtained by the control device 402 is greater than or equal to the preset humidity value, the control device 402 controls the cooking assembly 30 to stop working and sends out a steam leakage alarm message.

In addition, the control device 402 can also analyze the position of the humidity sensor 401 with the detected humidity value greater than or equal to the preset humidity value, determine the occurrence position of the vapor leakage fault, feed back the occurrence position of the vapor leakage fault to the user through the display screen 70, receive vapor leakage alarm information, contact the maintenance staff to report the fault, and the maintenance staff can quickly repair the vapor leakage fault according to the information of the occurrence position of the vapor leakage fault on the display screen 70.

Therefore, the household steam oven 100 provided by the utility model can timely find out the steam leakage of the inner container 20, so that the problem that the steam leakage is difficult to find and continuous when the steam leakage of the inner container 20 occurs can be solved.

In order to further improve the repairing efficiency of the steam leakage fault of the domestic steam oven 100, as shown in fig. 2, the domestic steam oven 100 further includes a plugging assembly 50, and the plugging assembly 50 can plug and repair the steam leakage fault when detecting that the domestic steam oven 100 has the steam leakage fault.

The closure assembly 50 includes a storage box 501, a plurality of pipes 502 and a plurality of solenoid valves 503, the storage box 501 being formed with a storage cavity 5011 and a plurality of first outlets 5012 communicating with the storage cavity 5011, the storage box 501 being for storing glue. A first end of one of the pipes 502 communicates with a first outlet 5012 of the cartridge 501, and a second end of one of the pipes 502 is provided at one of the connection holes 202. The plurality of solenoid valves 503 are all electrically connected with the control device, and one solenoid valve 503 is connected with one pipeline 502, and the solenoid valve 503 is used for conducting or closing the pipeline 502.

Thus, when the humidity sensor 401 detects that the household steam oven 100 has a steam leakage fault, the control device 402 controls the electromagnetic valve 503 corresponding to the steam leakage fault to be opened according to the information of the steam leakage fault occurrence position, glue flows out from the storage cavity 5011 of the storage box 501, flows through the first outlet 5012, the electromagnetic valve 503 and the pipeline 502 in sequence to reach the steam leakage fault occurrence position, the glue reaches the fault occurrence position, and the air is solidified, so that the steam leakage fault occurrence position is blocked, the steam leakage fault is not leaked any more, the automatic repair of the steam leakage fault can be completed, and the repairing efficiency of the steam leakage fault is further improved. After the repair of the leakage fault, the control device 402 will close the solenoid valve 503.

In some embodiments, with continued reference to fig. 2, the solenoid valve 503 is provided with a first inlet 5031 and a second outlet 5032, the first inlet 5031 of the solenoid valve 503 is connected to the first outlet 5012 of the reservoir cartridge 501, and the second outlet 5032 of the solenoid valve 503 is connected to the first end of the tubing 502.

It can be appreciated that when the detection control device 402 detects that the household steam oven 100 has a steam leakage fault, the control device 402 opens the electromagnetic valve 503, so that the first inlet 5031 and the second outlet 5032 of the electromagnetic valve 503 are communicated, and glue flows out of the storage cavity 5011 of the storage box 501, then flows through the first outlet 5012, the first inlet 5031 and the second outlet 5032, and the pipeline 502 sequentially, reaches the steam leakage fault occurrence position, and repairs the steam leakage fault.

As shown in fig. 3, after repairing the leakage fault, a part of glue will remain inside the pipe 502, and the part of glue will solidify when encountering air, and when the plugging assembly 50 needs to repair the same fault point again, the part of solidified glue may block the pipe 502, so that the leakage fault cannot be repaired.

In order to solve the problem of blockage of the pipeline 502 by residual glue in the pipeline 502, a heating wire 504 needs to be arranged in the pipe wall of the pipeline 502 or on the outer wall surface of the pipeline 502, when the plugging assembly 50 needs to repair the same fault point again, the control device 402 controls the heating wire 504 to be connected with a circuit, the heating wire 504 starts to heat the solidified glue in the pipeline 502, so that the solidified glue is melted until the solidified glue can flow, the glue in the pipeline 502 flows to the place where the steam leakage fault occurs, and air solidification is encountered to repair the steam leakage fault. After the fault is repaired, the control device controls the heating wire 504 to break the circuit, and the heating wire stops working.

It should be noted that, the glue has high temperature resistance, and at 250 degrees celsius, the glue will solidify when encountering air, and change from a liquid state to a solid state, and then enter a liquid state in the air-insulated storage cavity 5011. The heating wire 504 can raise the temperature of the glue in the pipeline 502 to 270 ℃ so that the glue in the pipeline 502 is recovered from a solid state to a liquid state and has fluidity again, and the melted glue can be solidified again when encountering air, so as to block the occurrence position of the steam leakage fault. The temperature of the liner 20 is below 250 ℃, so that solidified glue can not be melted, and the leakage blocking failure caused by the fact that the glue flows out from a leakage fault occurrence position after the glue is heated and melted is prevented.

In some embodiments, the conduit 502 is made of a metal material, such as copper, aluminum alloy, etc., in order to provide better heat conduction to the conduit 502, and thus to allow the heat generated by the heater wire 504 to be quickly conducted to the glue within the conduit 502.

To further increase the efficiency of the leak detection, in some embodiments, as shown in fig. 4 and 5, the monitoring control assembly and the plugging assembly are typically used in conjunction with a leak detection control method.

Specifically, the humidity sensor can detect the humidity value at the connecting hole, the control device can acquire the humidity value detected by the humidity sensor 401 once every a preset period of time, the control device compares the acquired humidity value with the preset humidity value, and when the acquired humidity value is smaller than the normal humidity value, the household steam oven works normally.

When the acquired humidity value is greater than or equal to a preset humidity value, the control device controls the cooking assembly to stop working, sends out primary steam leakage alarm information, and controls the display screen to display the primary steam leakage alarm information so as to remind a user of paying attention to the leakage of the liner. The control device controls the electric heating wire to be connected with a circuit, starts to heat the glue in the pipeline, then controls the electromagnetic valve to be opened, the glue flows into the pipeline from the storage box through the electromagnetic valve, flows to the connecting hole through the pipeline, and seals the steam leakage position of the connecting hole.

After the plugging is completed, the humidity sensor continuously detects, the control device counts the number of times of leakage of the plugging position, and when more than two times of humidity values are detected to be greater than or equal to a preset humidity value, the control device 402 sends out advanced leakage alarm information and displays the advanced leakage alarm information on the display screen 70, so that a user is reminded to contact with a maintainer to report and repair faults.

In some embodiments, the household steam oven can be further provided with an audible and visual alarm device, when the control device sends out the steam leakage alarm information, the control device controls the audible and visual alarm device to send out different alarm reminding signals according to the alarm information level (primary or advanced).

As shown in fig. 6, in order to install the humidity sensor 401 at the connection hole 202, the home steam oven 100 further includes a connection assembly 60, and the humidity sensor 401 is connected at the connection hole 202 through the connection assembly 60.
