Description

Technical Field

[0001] The utility model relates to the technical field of instant hot water faucets, in particular to an instant hot water faucet with a temperature control and reset structure. Background Art

[0002] Instant hot water faucets can heat the outlet water quickly. Due to the convenience of taking hot water, their use has become more and more common. An inner tank is usually set in the faucet, and the inner tank includes an upper cover, a heating water chamber, and a lower seat. A water inlet assembly is set in the lower seat for water to enter, and the water is heated by the heating water chamber and finally flows out from the outlet pipe at the upper cover. A main control assembly is also set in the lower seat for controlling the heating power and connecting the power supply. An extension seat is provided on one side of the lower seat, and a water flow regulating mechanism is provided at the extension seat. The handle of the water flow regulating mechanism is rotated to adjust the size of the outlet water flow. A temperature control reset structure is usually set on the upper part of the instant hot water faucet. The temperature control reset structure of the existing instant hot water faucet is not convenient to install or maintain, and the temperature sensing probe only measures the outlet water temperature and cannot control the outlet water temperature, so that the heating tube continues to heat the water in the heating water chamber. The outlet water temperature is too high and can easily cause scalds to the user. Summary of the invention

[0003] The embodiment of the present application provides an instant hot water faucet with a temperature control reset structure. The temperature of the water in the heating water chamber is sensed by a temperature-sensing surface provided at the lower end of the thermostat. If the water temperature is too high, the thermostat will fuse, thereby cutting off the current of the heating tube in the heating water chamber to avoid burns caused by excessive heating temperature.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hot water faucet with a temperature control reset structure, the hot water faucet comprising a shell, an upper cover, and a heating water chamber, the upper cover and the temperature control reset structure are arranged at the upper end of the shell, the heating water chamber is arranged inside the shell, the temperature control reset structure comprises a thermostat, a mounting seat, and a cover plate, the mounting seat is arranged inside the upper cover, a cavity is arranged inside the mounting seat, the thermostat is arranged inside the cavity, the cover plate is connected to the lower part of the mounting seat, a temperature sensing surface is arranged at the lower end of the thermostat, and the cover plate is provided with a first through hole connecting the temperature sensing surface and the heating water chamber.

The thermostat is connected in series in the heating circuit of the heating tube and is connected to the live wire of the heating circuit. A temperature sensing surface is provided at the lower end of the thermostat. The heated water in the heating water chamber enters the first through hole, and the temperature sensing surface senses the water temperature of the heating water chamber. If the water temperature is too high, the thermostat is melted, thereby cutting off the current of the heating tube in the heating water chamber, and the heating tube stops heating. When the temperature drops, that is, when the hot water tap comes out, the thermostat is reconnected, and the heating tube starts the heating process again, thereby avoiding burns caused by excessive heating temperature.

[0007] The upper end of the cover plate is connected to the lower end of the mounting seat, thereby limiting the temperature controller.

[0009] As an improvement, a rubber ring is provided between the mounting seat and the cover plate. The rubber ring is an elastic member. The lower end of the rubber ring abuts against the upper end of the cover plate, and the upper end of the rubber ring abuts against the lower end of the thermostat to prevent water from flowing into the cavity through the gap between the mounting seat and the cover plate.

[0010] As an improvement, the cover plate is provided with a first annular groove, and the lower end of the rubber ring is provided with a first annular boss adapted to the first annular groove, so as to facilitate the positioning of the first rubber ring when it is installed into the cover plate and prevent the first rubber ring from radial movement after installation.

[0011] As an improvement, a second annular groove is provided at the lower end of the temperature controller, and a second annular boss is provided at the upper end of the rubber ring. The upper surface of the second annular boss abuts against the bottom surface of the second annular groove, which can enhance the sealing of the temperature control reset structure and prevent water from entering the cavity when the temperature sensing surface senses the temperature of the water in the heating water cavity.

[0012] As an improvement, fixing blocks are provided on both sides of the cover plate, and the mounting seat is provided with connecting blocks corresponding to the fixing blocks. Threaded holes are provided inside the connecting blocks, and the fixing block is provided with a third through hole. The connecting screws pass through the third through hole and are threadedly connected to the threaded holes. The cover plate and the mounting seat are connected by the connecting screws. When the thermostat needs to be installed and repaired, it is only necessary to turn the connecting screws to separate the cover plate from the mounting seat, so as to put in, take out or replace the thermostat.

[0013] As an improvement, a wiring lug is provided at the upper end of the temperature controller, and a fourth through hole, a conductive sheet and a baffle are provided at the upper end of the upper cover. The wiring lug passes through the fourth through hole and is arranged at the upper end of the upper cover. The baffle is arranged between the wiring lug and the conductive sheet. The upper end component of the upper cover is relatively compact. The wiring lug is connected to the live wire of the heating circuit, and the conductive sheet is connected to the neutral wire of the heating circuit. A baffle is provided between the wiring lug and the conductive sheet to prevent conduction between the wiring lug and the conductive sheet. BRIEF DESCRIPTION OF THE DRAWINGS
