Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a high-flow instant hot water purifier that uses battery energy storage. Background Technology

[0002] With the improvement of living standards, the demand for high-flow hot water is increasing. Traditional under-sink instant water purifiers are limited by household 10A sockets and power cords, and the instant heating element power is only about 2100W, resulting in a hot water flow rate of only 350ml-400ml / min, which seriously affects the user experience. To address the above problems, existing under-sink instant water purifiers mostly use heat exchange technology in a hot water tank or preheating tank to achieve a high flow rate, but this technology has obvious drawbacks: 1) Heat exchange in the hot water tank is prone to repeated heating, resulting in high energy consumption; 2) During heat exchange in the preheating tank, the water temperature fluctuates greatly, the hot water flow rate is unstable, and the temperature control accuracy is low. Utility Model Content

[0003] The present invention aims to overcome the defects in the prior art and provide a high-flow instant hot water purifier that uses battery energy storage. It can stably output water at different temperatures in a large flow rate by controlling the first heating element to work alone or by the first heating element and the second heating element to work together through the control module.

[0004] To achieve the above objectives, this utility model provides a high-flow instant hot water purifier using battery energy storage, including a control module, a device inlet, a first pump body, a filter assembly, a first heating element, and a water outlet. The first pump body is used to pump water filtered by the filter assembly to the first heating element, and the water after passing through the first heating element is output from the water outlet. The device also includes a second heating element disposed in front of the first heating element so that the filtered water flows sequentially through the second heating element and the first heating element. The second heating element has a battery module for powering itself.

[0005] The filter assembly is further configured such that: the filter assembly includes a pre-filter, a reverse osmosis membrane filter, and a post-filter; the pre-filter is disposed on the pipeline between the equipment inlet and the first pump body; and the reverse osmosis membrane filter and the post-filter are disposed sequentially on the pipeline between the first pump body and the second heating element.

[0006] The device is further configured to include a reflux solenoid valve, wherein the inlet of the reflux solenoid valve is connected to the pipeline between the reverse osmosis membrane filter element and the post-filter element, and its outlet is connected to the pipeline between the pre-filter element and the first pump body.

[0007] A further configuration is provided: an inlet solenoid valve is installed on the pipeline between the outlet access point of the reflux solenoid valve and the pre-filter element.

[0008] A further configuration is provided: a second pump body is installed on the pipeline between the second heating element and the first heating element.

[0009] The following configuration is further provided: a first temperature probe is provided on the pipeline between the post-filter and the second heating element; a second temperature probe is provided on the pipeline between the second heating element and the second pump body; and a third temperature probe is provided on the outlet section of the first heating element or on the pipeline between the first heating element and the water faucet.

[0010] Compared with the prior art, the present invention has a simple and reasonable structure. The control module can control the working state of the first and second heating elements according to the water temperature and in combination with the temperature probe to accurately output water. At the same time, the second heating element, which is powered by the battery module, preheats the water flowing through it before it is heated by the first heating element, thus achieving a stable large flow rate of water output.

[0013] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0014] This utility model relates to a high-flow instant hot water purifier using battery energy storage, such as... Figure 1 As shown, the device includes a control module 1, a water inlet 2, a first pump body 5, a filter assembly, a second heating element 10, a first heating element 8, and a water outlet 9. The first pump body 5 pumps the water filtered by the filter assembly sequentially through the second heating element 10 and the first heating element 8, and finally outputs it through the water outlet 9. The first heating element 8 is powered by mains electricity, and the second heating element 10 has a battery module 11 for powering itself. The control module 1 controls the first heating element 8 to work alone or the first heating element 8 and the second heating element 10 to work together to stably output hot water of different temperatures in a large flow rate.

[0015] In this embodiment, the filtration assembly includes a pre-filter 3, a reverse osmosis membrane filter 6, and a post-filter 7. The pre-filter 3 is installed on the pipeline between the device inlet and the first pump body 5. The reverse osmosis membrane filter 6 and the post-filter 7 are sequentially installed on the pipeline between the first pump body 5 and the second heating element 10. Thus, the combined filtration of the pre-filter 3, reverse osmosis membrane filter 6, and post-filter 7 enables the municipal water supply to meet drinking standards. Preferably, the instant water purifier also includes a reflux solenoid valve 13. The inlet of the reflux solenoid valve 13 is connected to the pipeline between the reverse osmosis membrane filter 6 and the post-filter 7, and its outlet is connected to the pipeline between the pre-filter 3 and the first pump body 5. At the same time, a second pump body 12 is installed on the pipeline between the second heating element 10 and the first heating element 8. Thus, by opening the reflux solenoid valve 13 and controlling the PWM of the first pump body 5 and the second pump body 12, the water flow rate can be adjusted.

[0016] In the above scheme, an inlet solenoid valve 4 is installed on the pipeline between the outlet access point of the reflux solenoid valve 13 and the pre-filter 3. Thus, the control module 1 can conveniently control the opening or closing of the water purifier's inlet pipeline by controlling the opening or closing of the inlet solenoid valve 4.

[0017] In this embodiment, a first temperature probe 14 is installed on the pipeline between the post-filter 7 and the second heating element 10, a second temperature probe 15 is installed on the pipeline between the second heating element 10 and the second pump body 12, and a third temperature probe 16 is installed on the outlet section of the first heating element 8 or on the pipeline between the first heating element 8 and the water tap 9. In this way, hot water of the corresponding temperature can be output more accurately through the first to third temperature probes 16.

[0018] Compared with the prior art, the present invention has a simple and reasonable structure. The control module can control the working state of the first and second heating elements according to the water temperature and in combination with the temperature probe to accurately output water. At the same time, the second heating element, which is powered by the battery module, preheats the water flowing through it before it is heated by the first heating element, thus achieving a stable large flow rate of water output.

[0019] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
