Embodiment 1

[0028] This preferred embodiment provides a water outlet and inlet valve assembly for a water heater. Such as figure 1 and figure 2 As shown, the valve assembly includes a housing 1 and a valve core 2 arranged in the housing 1; the upper part of the housing 1 is provided with a casing port 11 for drainage and air intake, and the lower part is provided with an air inlet 12 and a drain port 13 ; The casing port 11 is provided with a hollow air pipe 3; the valve core 2 includes two spherical structures with passages inside, the first spherical structure 21 is used to communicate or shut off the intake passage, and the second spherical structure 22 is used for Connect or shut off the water outlet channel. The first spherical structure 21 and the second spherical structure 22 are fixedly connected (forming a gourd-like structure).

[0029] The spool 2 is composed of two parts, one part is used to connect or shut off the intake passage and the other part is used to connect or sh...

Embodiment 2

[0036] This preferred embodiment provides a water outlet and inlet valve assembly for a water heater, the structure of which is basically the same as that of the first preferred embodiment. The valve assembly includes a housing and a valve core arranged in the housing; a sleeve port for drainage and air intake is provided on the upper side of the housing, and an air inlet and a water discharge port are provided on the lower side; the valve core includes two internal passages respectively The spherical structure, the first spherical structure is used to connect or shut off the air intake passage, and the second spherical structure is used to connect or shut off the water outlet passage.

[0037] The difference is that: the specific structure of the intake channel on the first spherical structure is not limited, and it only needs to realize the connection or closure of the intake channel when the valve core rotates to different angles; the connection between the first spherical s...

Embodiment 3

[0039] This preferred embodiment provides a water heater. Such as Figure 4 As shown, the water heater includes a casing 6, an inner tank 7 and the water outlet and inlet valve assembly as described in the preferred embodiment 1 or 2. The air pipe 3 and the water outlet hole 4 are located in the inner tank 7 , and the casing 1 and the valve core 2 are at least partly located outside the casing 6 .

Abstract

The invention discloses a water heater water outlet and air inlet valve assembly and a water heater and belongs to the field of water heaters and parts thereof. The water heater water outlet and air inlet valve assembly is designed to solve the problem that existing devices are difficult to machine and comprises a shell and a valve element arranged in the shell. A sleeve opening used for draining water and sucking air is formed in the upper portion of the shell, and an air inlet and a drain outlet are formed in the lower portion of the shell. The valve element comprises two spherical structures internally provided with channels separately, the first spherical structure is used for communicating with or switching off an air inlet channel, and the second spherical structure is used for communicating with or switching off a water outlet channel. The water heater comprises a shell, a liner and the water outlet and air inlet valve assembly. An air pipe and a water outlet hole are located in the liner. The water heater water outlet and air inlet valve assembly and the water heater are easier to machine, low in cost, good in water outlet and air inlet effect, capable of draining water and sucking air at the same time or only sucking air without draining water and more convenient to use.

Description

technical field [0001] The invention relates to the field of water heaters and accessories thereof, in particular to a water outlet and inlet valve assembly for a water heater and a water heater equipped with the water outlet and inlet valve assembly. Background technique [0002] During the use of the water heater, there will be scale or impurities deposited on the bottom of the liner, which needs to be washed and discharged with water. However, drainage alone will cause the water pressure in the inner tank to decrease, the water flow speed will slow down, and the sewage cannot be completely discharged. [0003] There is an automatic drainage system for water heaters, which includes a drainage ball valve connected to the inner tank of the water heater and an inner tank water cut-off valve arranged on the water inlet pipeline of the inner tank. There is an air input hole on the wall, and the ball valve core is driven by a one-key switch to rotate to open the drain ball valv...
