[0059] Referring to the drawings Figures 1-6The embodiment provides a steam box, which comprises a heating disc 13 arranged in the steam box 20 and having a water tank; a first electrode 14 and a second electrode 15, the first electrode 14 and the second electrode 15 are arranged at intervals, and at least part of the first electrode 14 and at least part of the second electrode 15 extend into the water tank; a detection circuit for detecting the resistance value between the first electrode 14 and the second electrode 15, which has an input end and an output end 19, the first electrode 14 and the second electrode 15 are connected in series at the input end, the resistance value between the first electrode 14 and the second electrode 15 can change with the change of the conductive medium, and the output end 19 can output the corresponding voltage value according to the change of the resistance value.

[0060] It should be noted that: in the embodiment, by extending at least part of the first electrode 14 and at least part of the second electrode 15 into the water tank, and by the voltage change of the output end 19 of the detection circuit, the resistance value change between the first electrode 14 and the second electrode 15 can be directly reflected, and then the normal operation state, the water shortage state and the descaling state of the heating disc 13 can be accurately determined, the rapid identification of the working state can be realized, the water can be added or the scale can be removed in time, the influence of scale accumulation on the heat transfer effect of the heating disc can be avoided, the dry burning of the heating disc 13 can be avoided, the service life of the heating disc 13 can be prolonged, and the safety hazard can be avoided.

[0061] Specifically, the conductive medium between the first electrode 14 and the second electrode 15 is different, and the voltage value output by the output end 19 is also different, so that the resistance change between the first electrode 14 and the second electrode 15 can be directly observed by acquiring the voltage value of the output end 19, and then it can be determined that the heating disc 13 is in which working state; the first electrode 14 and the second electrode 15 are arranged at intervals, the first electrode 14 and the second electrode 15 are connected through the conductive medium in the water tank, in the case that there is water in the water tank, the first electrode 14 and the second electrode 15 are connected through the water, in the case that there is scale in the water tank, the scale covers part of the first electrode 14 and part of the second electrode 15, and the first electrode 14 and the second electrode 15 are connected through the scale; in the case that there is water shortage in the water tank, the first electrode 14 and the second electrode 15 are in the disconnected state.

[0062] Specifically, the heating disc 13 comprises the water tank and a heating piece, the heating piece is fixedly connected with the water tank, and the heating piece is used for heating the water tank.

[0064] Specifically, the cathode of the third electrode and the anode of the fourth electrode are located in the same plane, and the height of the plane is higher than the plane in which the cathode of the first electrode 14 and the anode of the second electrode 15 are located, so that the third electrode and the fourth electrode can achieve preliminary early warning. When the third electrode and the fourth electrode show a water shortage signal, water can be added to the heating disc in advance to avoid dry burning and improve the service life of the heating disc.

[0065] Further, along the height direction of the steaming box 20, there is a height difference between the cathode of the first electrode 14 and the cathode of the third electrode. The height difference is not limited and is set according to the actual situation as long as it can ensure preliminary early warning of the heating disc 13.

[0066] In other possible embodiments, the cathode of the first electrode 14, the anode of the second electrode 15, the cathode of the third electrode, and the anode of the fourth electrode are located in the same plane. The first electrode 14 and the second electrode 15 can display the state of the heating disc, and the third electrode and the fourth electrode can display the state of the heating disc, realizing redundant setting and ensuring the accuracy of the detection result.

[0067] In some possible embodiments, the detection circuit further includes a first resistor 16 and at least one set of voltage division branches. The first resistor 16 is connected in series between the second electrode 15 and the output terminal 19. The at least one set of voltage division branches is connected in parallel with the first resistor 16. In the case of water as the conductive medium, the first electrode 14 and the second electrode 15 are conductive, and the voltage value corresponding to the output terminal 19 is a first voltage value. In the case of water scale as the conductive medium, the first electrode 14 and the second electrode 15 are conductive, and the voltage value corresponding to the output terminal 19 is a second voltage value, which is greater than the first voltage value.

At the same time, when there is scale on the heating disc 13, it can be reminded to remove the scale in time to ensure the heating efficiency of the heating disc 13.

[0073] The application also protects a detection method for a steam oven. The method is applied to the steam oven as above, and the steam oven further comprises a counter for recording the length of time of water shortage or the length of time of scale removal.

It is also necessary to determine whether the duration that the voltage value is greater than the first preset voltage value meets the condition. Therefore, in the case where the voltage value is greater than the first preset voltage value, the timing mode of the counter needs to be started for auxiliary verification, so as to avoid false triggering and improve accuracy.

By acquiring the voltage value between the first electrode and the second electrode, the corresponding second timing duration can be monitored when the voltage value is greater than the second preset voltage value. If the timing duration is greater than the preset duration, it is determined that the heating disc is in the scale removal state, double detection is realized, false triggering is avoided, and the detection accuracy is improved.

[0094] In this embodiment, the voltage value greater than the first preset voltage value and the first timing duration greater than the preset duration need to be satisfied at the same time to determine that it is in the water shortage state. If the first timing duration is less than the preset duration, the corresponding data is re-acquired until the same condition is met to determine that the heating disc is in the water shortage state, double detection is realized, false triggering is avoided, and the detection accuracy is improved.

[0095] In this embodiment, the voltage value greater than the second preset voltage value and the second timing duration greater than the preset duration need to be satisfied at the same time to determine that it is in the water shortage state.
