Description

Technical Field

[0001] The utility model relates to the field of hydrogen production by electrolyzing water, and in particular to a self-adding deionized water device suitable for a hydrogen-rich water machine and a hydrogen-rich water machine. Background Art

[0002] A hydrogen-rich water machine is a device that can produce hydrogen-rich water; its working principle is to produce hydrogen through electrolysis of water and inject hydrogen into drinking water to obtain hydrogen-rich water.

[0003] At present, the main water electrolysis hydrogen production technology used by hydrogen-rich water machines is achieved through proton exchange membrane (PEM). However, proton exchange membrane (PEM) has very high requirements on water quality. Therefore, deionized water usually needs to be injected into the electrolytic water tank of the hydrogen-rich water machine. Otherwise, the proton exchange membrane (PEM) is easily damaged and unable to work to generate hydrogen-rich water, causing inconvenience and shortening the service life of the hydrogen-rich water machine.

[0004] However, although it is convenient to manually add deionized water to the hydrogen-rich water machine, it is easy to forget to add it, causing the hydrogen-rich water machine to fail to work properly.

[0005] In view of the fact that people tend to forget to add deionized water manually, some people have proposed to directly connect the electrolytic water tank of the hydrogen-rich water machine to the water inlet (such as tap water or mineral water), and use a multi-layer filter / core during the water filling process to filter the added water to obtain deionized water. Although this method can replenish deionized water for the hydrogen-rich water machine in a timely manner, it also has the following problems during use: (1) The filter / core has a service life and needs to be replaced regularly, which is costly; (2) It is impossible to accurately determine when the filter / core needs to be replaced. If the replacement is not timely, the deionized water injected into the electrolytic water tank will not meet the standards, which will also cause damage to the proton exchange membrane (PEM), affecting its use.

[0006] Therefore, a hydrogen-rich water machine that can achieve self-addition of deionized water and is lower in cost and more reliable is what we need to consider now. Utility Model Content

[0007] In order to solve the deficiencies in the prior art, the present application proposes a self-adding deionized water device and a hydrogen-rich water machine suitable for a hydrogen-rich water machine. The self-adding deionized water device can automatically add deionized water to the hydrogen-rich water machine without the need for manual addition of deionized water; it can ensure the stability and service life of the hydrogen-rich water machine. In addition, the self-adding deionized water device designed by the utility model can be used to transform the existing hydrogen-rich water machine, which has good universality and application prospects.

[0017] Furthermore, the cooling method of the condensing unit is water cooling, air cooling or a combination thereof.

[0018] Furthermore, the valve on the water inlet pipe side is an electrically controlled valve, and the electrically controlled valve cooperates with a water level sensor in the heating chamber.

[0019] Furthermore, a water level sensor is provided in the electrolytic water hydrogen production device to monitor the water level of deionized water in the electrolytic water hydrogen production device.

[0032] More preferably, a filtering device may be provided at the water inlet front side of the water inlet pipe 1 - 1 , and the filtering device may be used to perform pre-filtering treatment on the input water.

[0033] More preferably, the water inlet side of the water inlet pipe 1-1 can be directly connected to a tap water pipeline, or connected to a water storage container through a pump, a pipeline, etc.

[0034] More preferably, the valve on the water inlet pipe 1-1 side can be an electrically controlled valve, used in conjunction with the water level sensor in the heating chamber 1-4, that is, when the water level in the heating chamber 1-4 is lower than the set value, the valve on the water inlet pipe 1-1 side opens and water is automatically replenished into the heating chamber 1-4.

[0035] More preferably, a partition 1-3 is provided in the heating chamber 1-4, and the partition 1-3 divides the heating chamber 1-4 into two spaces connected at the bottom, the exhaust pipe 1-9 and the heater 1-5 are located in one space, and the water inlet pipe 1-1 and the drain pipe 1-6 are located in another space for increasing the water storage part; such a design can reduce the frequent opening and closing of the water inlet switch, while achieving rapid heating and temperature rise, generating steam, and quick response.

[0046] (4) Heater 1-5 is also equipped with a temperature sensor, which can automatically cut off the working circuit of heater 1-5 when the temperature is too high, thereby preventing dry burning and protecting the circuit.
