Therefore, the water heating method in the prior art is usually an electric heater or thick film heating.

[0003] However, the water heating method in the prior art has the following limitations: first, the heating efficiency of the above heating method is relatively low, resulting in a lot of heat loss; second, the problem of uneven heating will occur for over-current heating, that is, the water near the heating body has been heated or even boiled, but the water temperature far from the heating body is still relatively low, which is the so-called yin-yang water. Therefore, further improvements to the prior art are needed. Utility Model Content

[0022] Compared with the prior art, the advantages of the utility model are: the room temperature water downstream of the water tank is heated by a microwave heating device. Since microwave heating is a heating method that relies on an object to absorb microwave energy and convert it into thermal energy, so that the object itself is heated up as a whole at the same time, it is completely different from other conventional heating methods.

[0030] The water supply pipeline 1 also includes a filter element assembly arranged upstream of the water tank 2, and the filter element assembly includes at least two filter elements ( Figure 1 There are four middle filter elements, namely, a first-stage pre-treatment filter element 81, a second-stage pre-treatment filter element 82, a post-permeation membrane filter element 83 and a post-filter element 84. A second water pump 9 electrically connected to the controller 4 is provided upstream of one of the filter elements. Figure 1 The second water pump 9 is arranged upstream of the post-osmosis membrane filter element 83, and the second water pump 9 is a booster pump. In addition, the drinking water equipment also includes a water level detection module 22 for detecting at least two different water levels in the water tank 2. The water level detection module 22 is also electrically connected to the controller 4. The controller 4 is configured to control the start and stop of the second water pump 9 according to the detection result of the water level detection module 22. The water level detection module 22 in this embodiment is a liquid level float, which is used to detect three water levels, which are respectively recorded as low water level, middle water level and high water level; and an LED sterilizer 23 is also arranged in the water tank 2.

[0031] A first solenoid valve 101 is also provided on the water supply pipeline 1 downstream of the heating component 3, and the first solenoid valve 101 is electrically connected to the controller 4. Another branch is also branched out on the water supply pipeline 1 downstream of the heating component 3, and a fourth solenoid valve 106 is provided on the branch, and the output end of the branch is an emptying port 15; a second solenoid valve 102 is also provided on the pipeline 21, and the second solenoid valve 102 is electrically connected to the controller 4.

A third solenoid valve 103 and a one-way valve 104 are also provided on the waste water pipe 8a; the water supply pipeline 1 is also provided with a water inlet valve 105 ( Figure 1 The water inlet valve 105 is located between the first-stage pre-treatment filter element 81 and the second-stage pre-treatment filter element 82 , and the fourth solenoid valve 106 , the third solenoid valve 103 , the one-way valve 104 and the water inlet valve 105 are all electrically connected to the controller 4 .

[0032] The working process of the drinking water equipment in this embodiment is as follows:

[0033] Water production process:

[0034] When the liquid level float in the water tank 2 detects that the water level in the water tank 2 is lower than the low water level, the water inlet valve 105 and the second water pump 9 are opened by the control gas 4 to start water production. The water is filtered through the filter element assembly in turn, and the filtered clean water flows into the water tank 4. When the liquid level float in the water tank 4 detects the high water level, water production stops.

[0035] Process of taking normal temperature water:

[0036] When the controller 4 detects a signal to open the second solenoid valve 102, as long as the liquid level float in the water tank 2 detects that the water level in the water tank 2 is greater than the middle water level, the second solenoid valve 102 can be opened at this time, and the system starts to make water when the liquid level float detects a low water level; at the same time, if the controller 4 receives a signal to open the second solenoid valve 102, there will be a voice reminder to make water, and normal temperature water can only be taken after the water level in the water tank 2 is detected to be higher than the low water level;

[0037] Hot water taking process:

[0038] When the controller 4 detects the signal to open the first solenoid valve 101, it first needs to detect whether the water level in the water tank 2 is greater than the low water level. Only when it is greater than the low water level can the hot water taking logic be entered. At this time, the first water pump 6 is turned on, the microwave heating device 32 is turned on, and the first solenoid valve 101 is turned on.

[0039] The working flow rate of the first water pump 6 varies according to the temperature of the water intake. Since the upper limit of the microwave heating power of the microwave heating device 32 is fixed, the water flow rate at different water outlet temperatures is different. The temperature detected by the second temperature detection module 72 will be directly displayed on the water intake interface of the machine. The system presets four modes of temperature: 45°C, 65°C, 85°C, and 95°C (different water outlet temperatures can also be set according to actual needs). Before taking hot water, you need to pre-select the water outlet temperature and then take water.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
