[0040] Embodiment 1

[0041] The water tank assembly provided by the embodiment of the utility model includes a water tank 100, an electromagnetic detector 200 and a control module 300; the electromagnetic detector 200 is installed on the side wall of the water tank 100; the electromagnetic detector 200 includes a transmitting part 210 and a receiving part 220 arranged relatively to each other, the transmitting part 210 transmits an electromagnetic signal according to a preset frequency, and the receiving part 220 is used to receive the electromagnetic signal; the transmitting part 210 and the receiving part 220 are both electrically connected to the control module 300.

[0042] Specifically, see Figure 4 , the water tank 100 is set as a rectangular parallelepiped. Furthermore, the water tank assembly includes a display module and a control module 600 connected to the control module 300 by signal. The display module is used to display the information output by the control module 300, so that the user can read the information easily; the control module 600 is used for the user to transmit instructions to the control module 300. For example, when the user presses the water level measurement key of the control module 600, the control module 600 transmits the instruction of water level measurement to the control module 300. After receiving the instruction, the control module 300 controls the transmitting part 210 and the receiving part 220 of the electromagnetic detector 200 to operate so as to detect the water level. Furthermore, the transmitting end of the transmitting part 210 and the receiving end of the receiving part 220 form an angle, and the angle can be set to 50°, 60° or 70°.

[0043] See also Figure 1 When there is no water at the bottom of the water tank 100, the control module 300 controls the transmitting unit 210 of the electromagnetic detector 200 to transmit an electromagnetic signal at a preset frequency. The electromagnetic signal is reflected by the side wall of the water tank 100 to the receiving unit 220. The receiving unit 220 can receive the signal and the received electromagnetic signal meets the requirements. The control module 300 can output the information that there is no water at the bottom of the water tank 100 based on the information. Please refer to Figure 2 When there is water at the bottom of the water tank 100, the control module 300 controls the transmitting unit 210 of the electromagnetic detector 200 to transmit electromagnetic signals at a preset frequency. The electromagnetic signals are refracted by water, so that the receiving unit 220 cannot receive the signals or the received electromagnetic signals do not meet the requirements. The control module 300 can output the information that there is water at the bottom of the water tank 100 based on the information. Through the cooperation of the control module 300, the transmitting unit 210 and the receiving unit 220 of the electromagnetic detector 200, it is possible to detect whether there is water at the bottom of the water tank 100; if there is scale or poor water quality in the water tank 100, it will not affect the transmitting unit 210 of the electromagnetic detector 200 to transmit electromagnetic signals, the receiving unit 220 to receive electromagnetic signals, and the output of information by the control module 300, thereby avoiding the problem of inaccurate water level detection of the water tank 100 and improving the reliability of water level detection of the water tank 100. In addition, the water tank assembly is applied to steaming and baking equipment and is placed inside the steam generator. The electromagnetic signal is not easily disturbed by external light, which reduces the increase in product cost due to the placement of light-blocking plates and makes the detection structure more reliable.

[0044] The shape and structure of the water tank assembly are described in detail below:

[0045] In an optional solution of the embodiment of the utility model, a transparent area is provided at a position corresponding to the water tank 100 and the electromagnetic detector 200 .

[0046] Specifically, the transparent area may transmit electromagnetic signals, but the transparent area is not limited to a transparent color.

[0047] When there is water at the transparent area of ​​the water tank 100, the electromagnetic signal emitted by the transmitting unit 210 can pass through the side wall of the water tank 100 and be refracted by the water, thereby determining whether there is water at the corresponding position of the water tank 100 by judging whether the transmitting unit 210 receives a signal.

[0048] As another embodiment, the side walls of the water tank 100 are all configured to be transparent.

[0049] In an optional solution of the embodiment of the utility model, the electromagnetic signal is set to infrared.

[0050] Specifically, the electromagnetic detector 200 is configured as an infrared pair tube, which includes a transmitter 210 and a receiver 220; the infrared pair tube is placed around the water tank 100. If there is no water at the position corresponding to the electromagnetic detector 200 in the water tank 100, the infrared rays emitted by the transmitter 210 are refracted back to the receiver 220 via the side wall of the water tank 100, and the waveforms are consistent, it can be determined that the current position is in a water-free state; if there is water at the position corresponding to the electromagnetic detector 200 in the water tank 100, the waveform of the infrared rays emitted by the transmitter 210 is inconsistent with the waveform of the infrared rays received by the receiver 220, or the receiver 220 does not receive the infrared rays, it can be determined that the current position is in a water-containing state. The model of the infrared pair tube can be selected according to the actual usage and the size of the water tank 100 of different models.

[0051] The electromagnetic detector 200 is configured as an infrared pair tube, which has a simple structure and is easy to install and use.

[0052] In an optional scheme of an embodiment of the utility model, the frequency of the square wave emitted by the transmitting unit 210 is f1, and the receiving unit 220 receives a waveform (f1-x)<f1<(f1+x), where x is the fault tolerance value of the waveform. At this time, it can be determined that the position of the water tank 100 corresponding to the electromagnetic detector 200 is without water. Conversely, if the signal received by the receiving unit 220 is wrong or there is no signal, it is determined that the position of the water tank 100 corresponding to the electromagnetic detector 200 is with water.

[0053] In an optional solution of the embodiment of the utility model, the water tank assembly includes a water pump 400 and a drainage pump 500 , the water pump 400 is connected to the water inlet of the water tank 100 , and the drainage pump 500 is connected to the drainage outlet of the water tank 100 .

[0054] Specifically, the water pump 400 is connected to the water inlet of the water tank 100 through a water pipe, and the drainage pump 500 is connected to the drainage outlet of the water tank 100 through a water pipe.

[0055] The water pump 400 is used to inject water into the water tank 100 , and the drainage pump 500 is used to drain water from the water tank 100 , thereby replenishing or reducing the amount of water in the water tank 100 .

[0056] In an optional solution of the embodiment of the utility model, the water pump 400 and the drainage pump 500 are both electrically connected to the control module 300 .

[0057] Specifically, when the electromagnetic detector 200 located at the bottom of the water tank 100 detects that there is no water in the water tank 100 and the water tank 100 needs to store water, the control module 300 controls the water pump 400 to operate and inject water into the water tank 100; when the electromagnetic detector 200 located at the bottom of the water tank 100 detects that there is water in the water tank 100 and the water tank 100 needs to be drained, the control module 300 controls the drain pump 500 to operate and drain the water tank 100.

[0058] The control module 300 controls the opening and closing of the water pump 400 and the drainage pump 500 according to the detection result of the electromagnetic detector 200 and the actual demand of the water tank 100, so as to realize automatic filling and drainage of the water tank 100 and improve the automation degree of the water tank assembly.

[0059] In an optional solution of the embodiment of the utility model, a plurality of electromagnetic detectors 200 are provided, and the plurality of electromagnetic detectors 200 are arranged at intervals along the height direction of the water tank 100 .

[0060] Specifically, multiple electromagnetic detectors 200 are evenly arranged along the height direction of the water tank 100; or, multiple electromagnetic detectors 200 are arranged in a stepped manner along the height direction of the water tank 100; wherein the lowest electromagnetic detector 200 needs to be located at the bottom of the water tank 100 to measure whether there is water at the bottom of the water tank 100 to avoid the existence of a detection blind spot.

[0061] Multiple electromagnetic detectors 200 are all connected to the control module 300 by signal, so as to measure whether there is water at the positions corresponding to the multiple electromagnetic detectors 200 and the water tank 100, and further measure the current water level of the water tank 100; the control module 300 can rationally control the water pump 400 and the drainage pump 500 according to the current water level of the water tank 100.

[0062] In an optional solution of the embodiment of the present utility model, a plurality of electromagnetic detectors 200 are located on the same side of the water tank 100 .

[0063] See also Figure 4 , multiple electromagnetic detectors 200 are located on the same side of the water tank 100, which is convenient for installing the electromagnetic detectors 200.

[0064] In an optional solution of the embodiment of the utility model, multiple groups of electromagnetic detectors 200 are provided, and the multiple groups of electromagnetic detectors 200 are arranged at intervals along the circumference of the water tank 100; each group of electromagnetic detectors 200 includes at least one electromagnetic detector 200.

[0065] See also Figure 3 There are two groups of electromagnetic detectors 200, and the multiple electromagnetic detectors 200 in each group of electromagnetic detectors 200 are arranged at intervals along the height of the water tank 100, and the two groups of electromagnetic detectors 200 are arranged in a staggered manner, which increases the positions for water level detection and is more conducive to determining the current water level of the water tank 100. The actual position, number and arrangement of the electromagnetic detectors 200 on the water tank 100 can be changed, and are not limited to the positions shown in the figure, and can be placed at any position around the water tank 100 that can determine the water level change.

[0066] In an optional solution of the embodiment of the utility model, the control module 300 stores the device identification and water level height corresponding to each electromagnetic detector 200; the control module 300 controls each electromagnetic detector 200 to perform water level detection processing respectively.

[0067] Specifically, the control module 300 can control multiple electromagnetic detectors 200 to perform water level detection processing simultaneously, control a single electromagnetic detector 200 to perform water level detection processing, or control some electromagnetic detectors 200 among the multiple electromagnetic detectors 200 to perform water level detection processing.

[0068] The control module 300 stores the device identification and water level height corresponding to each electromagnetic detector 200. When detecting the actual water level of the water tank 100, the control module 300 controls multiple electromagnetic detectors 200 to start at the same time. The water level height corresponding to the electromagnetic detector 200 with the lowest position and a water level detection signal of no water is the current water level of the water tank 100. Starting multiple electromagnetic detectors 200 at the same time can quickly determine the current water level of the water tank 100, thereby improving the efficiency of the steaming and baking equipment. In addition, when it is actually necessary to detect whether the water in the water tank 100 has reached a certain water level height, the control module 300 controls the electromagnetic detector 200 corresponding to the water level height to start, and determines whether there is water at the water level height of the water tank 100, thereby realizing the detection of whether the water in the water tank 100 has reached a certain water level height according to actual needs, thereby realizing targeted detection and improving the intelligence of the steaming and baking equipment.

[0069] In an optional solution of the embodiment of the utility model, the control module 300 controls each electromagnetic detector 200 to perform water level detection processing in sequence according to the water level height sequence corresponding to the electromagnetic detector 200.

[0070] Specifically, the control module 300 controls multiple electromagnetic detectors 200 to perform water level detection processing one by one in a bottom-up order. When the water level detection signal generated by the electromagnetic detector 200 for the first time indicates that there is no water, the control module 300 controls to stop the water level detection. The water level height corresponding to the electromagnetic detector 200 below the electromagnetic detector 200 is the current water level of the water tank 100.

[0071] The control module 300 stores the device identification and water level height corresponding to each electromagnetic detector 200. When detecting the actual water level of the water tank 100, the multiple electromagnetic detectors 200 are controlled to be turned on in sequence according to the corresponding water level heights, so that the detection is stopped after the current water level of the water tank 100 is detected. There is no need to control all the electromagnetic detectors 200 to start up for detection, thereby achieving energy saving.

[0072] In an optional solution of the embodiment of the utility model, the electromagnetic detector 200 is installed on the outer wall of the water tank 100 .

[0073] Specifically, the electromagnetic detector 200 may be bonded or fixedly installed on the outer wall of the water tank 100 .

[0074] The electromagnetic detector 200 is installed on the outer wall of the water tank 100 so that the electromagnetic detector 200 does not contact the water inside the water tank 100, which facilitates maintenance and replacement of the electromagnetic detector 200.

[0075] As another implementation, the electromagnetic detector 200 is embedded in the inner wall of the water tank 100 .
