Problems solved by technology

The one-way valve can be opened and conducted in the direction of water outlet, and it is closed in the opposite direction. Only when the water pump is pressurized can the one-way valve be opened to realize water outlet. When in use, the air cannot enter the outlet pipe to reach the centrifugal water pump, and there is no water diversion in the centrifugal water pump, so the water in the liquid heater cannot be pumped out. It is necessary to inject water into the centrifugal water pump for the first time to pump water normally.
In addition, each time the water pump stops pumping water, the one-way valve is closed, and since there is no air entering between the water pump and the water outlet, there will always be residual water in the water outlet pipe between the two, which will breed bacteria for a long time and affect the quality of life. healthy
At the same time, since no air enters the outlet pipe, the residual water in the outlet pipe will not flow back, so it is impossible to accurately determine the height of the liquid level in the liquid heater

Embodiment 1

[0023] The present invention provides a liquid heater. In this embodiment, the liquid heater is an electric hot water bottle as an example, including a bottle body and an inner liner 1, a water pump 2 and a water outlet pipe 3 arranged on the bottle body, such as figure 1 As shown, the water pump 2 is connected to the inner tank 1. One end of the water outlet pipe 3 is connected to the water pump 2, and the other end is provided with a water outlet 31. The water outlet pipe 3 extends to a position above the rated maximum water level of the inner tank 1 and the height of the water outlet 31. Below the rated maximum water level M of the inner tank 1, an anti-siphon passage 4 is provided on the outlet pipe 3, and air enters the outlet pipe 3 through the anti-siphon passage 4 when the water pump 2 is stopped to prevent siphoning. First of all, after lowering the height of the water outlet 31, it can be closer to the container receiving water, reducing the splashing of hot water and r...

Embodiment 2

[0029] In addition to using a one-way valve or solenoid valve, it is also possible to design the inlet end of the anti-siphon passage 4 to be high enough relative to the top of the outlet pipe 3, and the water pump 2 is not enough to let water spray out from the anti-siphon passage 4, and the anti-siphon passage 4 Partly or completely higher than the height of the curved section 34, such as figure 2 As shown, all the anti-siphon passages 4 are higher than the height of the curved section 34. One end of the anti-siphon channel 4 is in the best communication with the curved section 34, and air can be fed into the water outlet pipe 3 in time when the water pump 2 stops working, and the siphon phenomenon can be quickly prevented from occurring.

[0030] The other end of the anti-siphon passage 4 may be located on the top or side of the bottle body or extend into the inner liner 1. In this embodiment, the other end of the anti-siphon channel 4 extends into the inner tank 1. Once an a...

Embodiment 3

[0033] In order to avoid setting the other end of the anti-siphon channel 4 too high to affect the design of the bottle body, the bending section 34 can be designed to include a water-gas separation cavity 35, such as image 3 As shown, the anti-siphon channel 4 is connected to the top wall of the water-gas separation chamber 35. The water-gas separation cavity 35 can store a certain volume of water, which can effectively prevent water from spraying from the other end of the anti-siphon channel 4.

Abstract

The invention discloses a liquid heater, belongs to the field of liquid heating appliances, and aims to solve the problem that a siphoning phenomenon occurs due to the fact that a water outlet is lowin height position. According to the technical scheme, the liquid heater mainly comprises a bottle body, a liner, a water pump and a water outlet pipe, wherein the liner, the water pump and the wateroutlet pipe are arranged in the bottle body, the water pump communicates with the liner, one end of the water outlet pipe communicates with the water pump, the other end of the water outlet pipe is provided with a water outlet, the water outlet pipe extends to the position above the rated highest water lever of the liner, the height position of the water outlet is lower than the rated highest water level of the liner, the water outlet pipe is provided with an anti-siphoning channel, and air enters the water outlet pipe through the anti-siphoning channel when the water pump is in a stop state so as to prevent siphoning. The liquid heater is mainly used for reducing the height position of the water outlet and preventing the siphoning phenomenon from occurring.

Description

Technical field [0001] The invention relates to household appliances, in particular to a liquid heater. Background technique [0002] For existing liquid heaters on the market (including drinking fountains, instant drinking fountains, and electric hot water bottles), the height of the water outlet is generally higher than the height of the maximum liquid level of the liquid heater. However, if the liquid heater has appearance or structure requirements, which causes the position of the water outlet to be lower than the rated maximum liquid level, when the pump stops, the height of the liquid heater is still higher than the height of the water outlet. The mouth will continue to discharge water due to the siphon principle until the liquid level is equal to or lower than the height of the water outlet, so abnormal water discharge occurs. [0003] In order to solve the problem of abnormal water output caused by the siphon principle, a solution of adding a one-way valve to the water out...
