Abstract

The invention relates to an automatic temperature control mixing valve for a water heater. According to the technical scheme, a square cavity (6) and a cylindrical cavity (17) are formed in a valve body (1), a spherical cavity (2) is formed in the upper portion of the cylindrical cavity (17), a first hot water inlet (15) and a first cold water inlet (14) are formed in the bottom of the cylindrical cavity (17), a temperature sensor (3) is arranged at a mixed water outlet (4) in the top of the spherical cavity (2), a valve element (12) is arranged in the cylindrical cavity (17) of the valve body (1), a driving part is arranged in the square cavity (6), an output shaft of a micro servo motor (18) is provided with a gear (7), and a rack (11) meshed with the gear (7) is connected with the valve element (12) through a connecting rod. A single-chip microcomputer (19) is arranged in a control panel (20) of the valve body (1). Temperature control software is programmed on the single-chip microcomputer (19). A port C and a port D of the single-chip microcomputer (19) are correspondingly connected with a positive interface and a negative interface of the micro servo motor (18). A port E of the single-chip microcomputer (19) is connected with the temperature sensor (3). The automatic temperature control mixing valve has the advantages of being convenient to operate, high in automation degree and accurate in temperature control.

Description

technical field [0001] The invention belongs to the technical field of automatic temperature control valves. Specifically relates to a temperature automatic control mixing valve for water heaters. technical background [0002] At present, the main technology of the water heater tends to be mature and has been widely used. The mixing valve is a very important temperature control device for water heaters, which is directly related to the comfort of people using hot water. [0003] "A ceramic valve assembly and a hot and cold water mixing valve equipped with the assembly" (ZL200610000129.8) patented technology, which includes a valve body, a handle, a ceramic valve core and a hot and cold water mixing valve installed under the ceramic valve core cavity. The ceramic spool can simultaneously adjust the flow rate of hot and cold water and the water intake ratio, which solves the problem of adjustable water flow. "A handle for a faucet with mixed hot and cold water" (ZL20131025...
