Description

Technical Field

[0001] This application relates to the field of water supply equipment structures. More specifically, this application relates to a gas removal assembly designed to provide improved gas removal capabilities. This application also relates to a hot water supply device that includes the aforementioned gas removal assembly. Background Technology

[0002] Water supply equipment, such as hot water supply systems, is used to treat domestic water, such as providing hot water to residential households. During the water supply and treatment process, some gases are inevitably entrained in the water and can accumulate at certain locations inside the pipes of the hot water supply system. For example, due to buoyancy, entrained air bubbles tend to rise and may accumulate at relatively high vertical positions within the pipes. Such bubble accumulation is generally undesirable because these bubbles may be carried into the operating components of the water supply equipment, adversely affecting the stability and lifespan of these components.

[0030] Figure 1 and Figure 2 This application illustrates various aspects of the gas purging assembly and hot water supply device. In one embodiment, the hot water supply device 1 can be configured to provide hot water, such as domestic hot water for residential use. In one embodiment, the hot water supply device 1 can be a wall-mounted boiler. The hot water supply device 1 may include a housing and several components disposed within the housing. In one embodiment, the hot water supply device 1 may include at least: a pump 20, an expansion tank, a gas purging assembly 10, etc. In one embodiment, the expansion tank may be located in... Figure 2 The location indicated by the middle arrow 30. In one embodiment, the expansion tank is concealed by sheet metal, and... Figure 2 It is invisible from the perspective of [the viewpoint].

[0031] The gas removal assembly 10 may include an inlet pipe 100, an outlet pipe 200, an air extraction device 300, and a fixing member 400, etc. The gas removal assembly 10 can be used to remove gases entrained in the water in the pipes of the hot water supply device 1, such as entrained air bubbles or gases generated for other reasons. In one embodiment, the gas removal assembly 10 may be disposed in the flow path of the working fluid of the hot water supply device 1, for example, downstream of the pump 20 and upstream of the expansion tank. In other words, according to one embodiment of the gas removal assembly 10 of this application, it may be connected between the pump 20 and the expansion tank.

[0032] The inlet pipe 100 and outlet pipe 200 can be any suitable metallic or non-metallic conduit, and may include an inlet and an outlet, and may include one or more bends. In one embodiment, the inlet and outlet of the inlet pipe 100 and outlet pipe 200 can have any suitable orientation. In one embodiment, the inlet pipe 100 may be located upstream of the flow path, and the outlet pipe 200 may be located downstream of the flow path. In one embodiment, the outlet end of the outlet pipe 200 is positioned higher than the inlet end of the inlet pipe 100 in the vertical or gravitational direction.

[0033] The vacuum device 300 may be configured as a generally cylindrical shape and may be disposed between the inlet pipe 100 and the outlet pipe 200 in the flow path. In one embodiment, the vacuum device 300 may include an inlet port 310, an outlet port 320, and an exhaust port 330. The inlet port 310 and the outlet port 320 may be disposed on the side of the exhaust device 300 and may be connected to the inlet pipe 100 and the outlet pipe 200, respectively. The exhaust port 330 may be disposed at one end of the exhaust device 300.

In use, the working fluid, including water, may carry air bubbles, such as air bubbles, as it travels in the flow path, or gases dissolved in the water may precipitate and form bubbles due to fluid flow and pressure changes. Under the influence of buoyancy, the air bubbles tend to rise in the air extraction device 300 and accumulate near the exhaust port 330. By discharging the air bubbles from the exhaust port 330, the air bubbles entrained in the water can be at least partially reduced or eliminated, thereby reducing the adverse effects of air bubbles downstream of the flow path, improving system operating efficiency, and extending service life.
