Embodiment 1

[0046] like figure 1 As shown, this embodiment provides an exhaust device, which includes a container 3 , an opening 6 is arranged on the container 3 , and the elastic membrane 1 is arranged at the position of the opening 6 to seal the opening 6 . The elastic membrane 1 described in this embodiment is made of elastic material, can be stretched and deformed, and has unidirectional air permeability.

[0047] In this embodiment, the container 3 contains gas or liquid, and the liquid or gas has a density difference from the gas to be discharged, and the gas to be discharged is stratified with the gas or liquid contained in the container itself. The opening 6 is arranged at the layered position where the gas to be discharged is located, that is, the elastic membrane 1 is arranged at the end where the gas to be discharged is layered, so that the elastic membrane 1 is in contact with the gas to be discharged. Especially for the liquid storage tank of the water heater, the density of...

Embodiment 2

[0059] like image 3 As shown, this embodiment provides an exhaust device, the main difference from the exhaust device in Embodiment 1 is that the exhaust port 2 is arranged on the container 3, and the elastic membrane 1 is arranged at a certain position of the container 3 On the inner wall, so that the elastic membrane 1 blocks the radial section of the container 3 at this position. The elastic membrane 1 separates the container 3 into two parts, one of which can collect the gas to be discharged, and the container 3 and the elastic membrane 1 of this part together form a stretchable chamber 8 .

[0060] In this embodiment, the elastic membrane 1 is fixed on the inner wall of the container 3, and the area of ​​the elastic membrane 1 is greater than the area of ​​the inner wall of the container 3 at the fixed position, so that the area of ​​the elastic membrane 1 has a margin except for covering the inner wall of the container 3 , so that the elastic film 1 can protrude from t...

Embodiment 3

[0064] like Figure 4 As shown, the present embodiment provides an exhaust device. The difference from the above-mentioned embodiments is that the container 3 of this embodiment is provided with an opening 6 connected to the exhaust channel 7, that is, the gas to be discharged in the container 3 directly enters the exhaust channel. 7. An elastic film 1 is arranged in the exhaust channel 7 , and the exhaust channel 7 is divided into two parts by the elastic film 1 , a part of which forms a telescopic chamber 8 , and a control valve 5 is provided in the telescopic chamber 8 .

[0065] The principle is the same as the above-mentioned embodiment, the elastic membrane 1 can form the elastic chamber 8 itself, or the elastic membrane 1 is arranged on the inner wall to form the elastic chamber 8, and the elastic chamber 8 collects the gas to be discharged. And when the gas to be discharged is collected to a set amount, the exhaust device starts to exhaust. The advantage of this embo...

Abstract

The invention provides an exhaust device. The exhaust device comprises a stretchable chamber arranged in a container and used for collecting gas in the container, an exhaust port is formed in the stretchable chamber, a control valve is arranged at the exhaust port and used for opening the exhaust port after the pressure of the gas in the stretchable chamber reaches a set value, the stretchable chamber is defined by an elastic film, and the elastic film is elastic, stretchable, deformable and breathable. In the field of water heaters, the exhaust device is arranged, the service life and heatingefficiency of the water heater are improved, noise of the water heater is reduced, the exhaust device provided by the invention starts exhausting only after a certain amount of gas is collected in the elastic film, and a valve body in the exhaust device can be prevented from being frequently opened and closed in the environment that the temperature of the water heater is frequently changed.

Description

technical field [0001] The invention belongs to the field of container or pipeline exhaust, in particular, relates to an exhaust device, and also relates to a water heater equipped with the above-mentioned exhaust device to discharge internal gas. Background technique [0002] In many fields, it is necessary to discharge the gas in the container or pipeline; for example, in the field of water heaters, due to high water temperature and high resistance, air bubbles are easily generated in the pipeline; if the air bubbles are not discharged in time, the air bubbles will flow through the water pump. Make the water pump vibrate or make abnormal sound; the bursting of air bubbles may cause water droplets to impact the impeller, which will affect the life of the water pump under the above working conditions for a long time; and once the air bubbles enter the pump body, it will affect the water absorption and drainage capacity of the water pump, and affect or make the effect of the p...
