Problems solved by technology

[0004] However, when the restrictor tube sprays water towards the tank body, water splashes will splash in the tank body, and the water splashes will cause detection errors in the liquid level detector, resulting in over-inflated or not inflated in time, and finally make the gas-dissolving effect poor

Embodiment 1

[0027] Embodiment one, such as Figure 1-Figure 2 As shown, this embodiment proposes a water-air mixing device with a non-contact liquid level detection function, including:

[0028] The tank body 1 is provided with a water inlet 11, a water outlet 12 and an air inlet (not shown);

[0029] A restrictor tube 2 , the restrictor tube 2 is arranged in the tank body 1 and communicated with the water inlet 11 .

[0030] In actual use, take the water-air mixing equipment with non-contact liquid level detection function used in conjunction with a water heater as an example. The water flow output from the water heater enters the restrictor pipe 2 through the water inlet 11 , and the water flow is sprayed into the dissolved air space formed in the tank body 1 through the water spray port 21 of the restrictor pipe 2 .

[0031] In order to control the air intake of the tank body 1 to meet the requirement of dissolved air, it is necessary to accurately control the water level in the tank...

Abstract

The invention discloses water-gas mixing equipment with a non-contact liquid level detection function, and the equipment comprises a tank body which is internally provided with a gas dissolving space; the flow limiting pipe is used for outputting water to the air dissolving space; the liquid level detector is used for detecting the liquid level in the tank body; wherein a water spraying opening of the flow limiting pipe is located in the tank body, the liquid level detector is arranged outside the tank body, and the water spraying direction of the liquid level detector is opposite to the water spraying direction of the water spraying opening. The external liquid level detector is adopted to detect the liquid level, so that the influence of water splashing is reduced, the detection accuracy is further improved, and the gas dissolving effect is optimized.

Description

technical field [0001] The invention belongs to the technical field of household appliances, in particular to a water-air mixing device with a non-contact liquid level detection function. Background technique [0002] At present, electric water heaters are household appliances commonly used in people's daily life. With the continuous development of technology, in order to improve the user's bathing experience, a water-air mixing device is usually configured to generate microbubble water. [0003] In the prior art, the water-air mixing device used with the water heater usually includes a tank body and a restrictor tube. The air in the water mixes to form dissolved air water. However, during use, in order to ensure that the water entering the tank can fully contact with the air, it is necessary to control the liquid level in the tank to reserve enough space to ensure that the air can contact with the water. This requires that the water outlet of the restrictor be higher tha...
