Problems solved by technology

[0002] In the related art, the existing one-way valve assembly used for water heaters is generally composed of a hot water joint, a connecting circlip, a filter screen, a one-way valve and a cold water joint, wherein the one-way valve is installed on the cold water joint for connecting with the hot water joint. At one end of the connection, the positive opening pressure of the one-way valve is provided by the internal spring of the one-way valve. The elastic force provided by the internal spring is generally a fixed value. There is a large water flow at the end, and the suction generated by the large water flow may cause the originally closed one-way valve to open by mistake, resulting in water channeling
[0003] If the one-way valve assembly is used in a gas water heater with circulation function, if the one-way valve is opened by mistake when the cold water valve is opened, water will flow in the circulating water circuit of the water heater, which may make the water heater functionally judged as necessary. Hot water, causing the water heater to be turned on by mistake for a short time, affecting the comfort of users

Embodiment 1

[0026] Embodiment one: if figure 1 , figure 2 and image 3 As shown, this embodiment provides a one-way valve assembly, which is applied to a water heater. The water heater generally has a hot water pipeline and a cold water pipeline. The one-way valve assembly includes a water inlet joint 1, a water outlet joint 2 and a one-way valve 3. The water joint 1 is set on the hot water pipeline of the water heater, the water outlet joint 2 is set on the cold water pipeline of the water heater, and the one-way valve 3 is connected between the water inlet joint 1 and the water outlet joint 2, and the one-way valve 3 includes a fixed end of the one-way valve 31. The movable end 32 of the one-way valve and the elastic member 33, wherein one end of the fixed end 31 of the one-way valve is set in the water outlet joint 2, the other end is set in the water inlet joint 1 and is fixedly connected with the water inlet joint 1, and the one-way valve moves The end 32 is movably arranged in th...

Embodiment 2

[0042] Embodiment two: if Figure 1 to Figure 4 As shown, this embodiment provides a water heater, including a hot water pipeline 81, a cold water pipeline 82 and a one-way valve assembly as described in Embodiment 1, and the one-way valve assembly is connected to the hot water pipeline 81 and the cold water pipe between road 82. Because of the one-way valve assembly as described in the first embodiment, the water heater provided by this embodiment has the advantages of reducing false opening of the one-way valve, avoiding short-term false opening of the water heater, and improving user comfort.

Abstract

The invention discloses a one-way valve assembly and a water heater. The one-way valve assembly comprises a water inlet connector, a water outlet connector and a one-way valve, wherein the one-way valve comprises a one-way valve fixed end, a one-way valve movable end and an elastic component, one end of the one-way valve fixed end is arranged in the water outlet connector, the other end of the one-way valve fixed end is arranged in the water inlet connector and is fixedly connected with the water inlet connector, the one-way valve movable end is movably arranged in the water inlet connector and is used for opening or closing the water inlet connector, the elastic component is abutted between the one-way valve fixed end and the one-way valve movable end, and the one-way valve fixed end andthe one-way valve movable end are in cooperation with each other to enable the water inlet connector to be connected with or disconnected from the water outlet connector so that the mis-opening phenomenon of the one-way valve can be reduced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a check valve assembly and a water heater. Background technique [0002] In the related art, the existing one-way valve assembly used for water heaters is generally composed of a hot water joint, a connecting circlip, a filter screen, a one-way valve and a cold water joint, wherein the one-way valve is installed on the cold water joint for connecting with the hot water joint. At one end of the connection, the positive opening pressure of the one-way valve is provided by the internal spring of the one-way valve. The elastic force provided by the internal spring is generally a fixed value. There is a large water flow at the end, and the suction generated by the large water flow may cause the originally closed one-way valve to open by mistake, resulting in water channeling. [0003] If the one-way valve assembly is used in a gas water heater with a circulation function, if th...
