Problems solved by technology

[0002] The inlet water temperature of the constant temperature water heater is too low during the heating process. When the water temperature difference set by the user is too large, the cold water flow rate of the water heater is fast during the non-constant temperature heating stage of the water heater, which will cause the water temperature to heat slowly, making it difficult to quickly reach the set temperature, resulting in poor bathing experience for the user. good

Embodiment 1

[0024] Such as figure 1 As shown, a water flow regulating device of this embodiment, the regulating device 1 includes a valve body 11 , a valve core 12 , a temperature sensing body 13 , a guide column 14 and an elastic member 15 . The valve core 12 is arranged in the valve body 11 in an axially movable manner, and the temperature sensing body 13 is arranged in the valve core 12 and expands or contracts according to the temperature change. One end of the guide post 14 is connected with the inner wall of the valve body 11, And its other end extends into the valve core 12 and abuts against the temperature sensing body 13 , one end of the elastic member 15 is fixed on the inner wall of the valve body 11 and the other end abuts against the valve core 12 . Thus, when the external temperature and / or the temperature of the water flowing through the valve core 12 changes, the temperature sensing body 13 expands or contracts according to the temperature change, and the valve core 12 aut...

Embodiment 2

[0035] Such as Figure 5 As shown, a water heater in this implementation includes a water outlet pipe 2, a water outlet joint 3, a controller 4 and a heater 5, one end of the water outlet pipe 2 communicates with the heater 5, and the other end communicates with the water outlet joint 3, wherein, It also includes a water flow regulating device as described in Embodiment 1, the regulating device 1 is arranged between the water outlet pipe 2 and the water outlet joint 3, and is used to automatically adjust the flow of water flowing out of the regulating device 1 according to the temperature of the water flowing through the regulating device 1 . Thus, when the temperature difference between the water in and out of the water heater in the non-constant temperature heating stage is large, the regulating device 1 can automatically reduce the water flow flowing out of the regulating device 1, otherwise it can automatically increase the water flow, and the adjustment method is sensitiv...

Abstract

The invention discloses a water flow adjustment device. The water flow adjustment device comprises a valve body, a valve element and an elastic piece, a water inlet and a water outlet are formed in the valve body, a through hole for water flow passing is formed in the valve element, a temperature sensing body capable of expanding or contracting according to the changing of the temperature is arranged in the valve element, the elastic piece is arranged between the valve element and the inner wall of the valve body, the valve element can perform axial motion under the action of combined action of the temperature sensing body and the elastic piece, and thus, a matching communicating state of the through hole, the water inlet and the water outlet is changed. Meanwhile, the invention further discloses a water heater provided with the water flow adjustment device. The water flow adjustment device and the water heater have the following advantages that 1, the water flow adjustment device automatically adjusts the water outlet amount according to the water temperature, the sensitivity of water flow adjustment is high; and 2, the water heater automatically adjusts the water outlet amount according to the adjustment device, meanwhile, load allowance is used for heating the water flow, double pipes enable the hot water outlet response speed of the water heater to be higher, a thermal equilibrium state is rapidly reached, and the water usage experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a water flow regulating device and a water heater for quickly constant temperature after startup. Background technique [0002] The inlet water temperature of the constant temperature water heater is too low during the heating process. When the water temperature difference set by the user is too large, the cold water flow rate of the water heater is fast during the non-constant temperature heating stage of the water heater, which will cause the water temperature to heat slowly, making it difficult to quickly reach the set temperature, resulting in poor bathing experience for the user. good. Contents of the invention [0003] The purpose of the present invention is to provide a water flow regulating device in view of the current technical situation, which can automatically adjust the water flow according to the water temperature. At the same time, a water heater is al...
