Background technology

At present, along with growth in the living standard and development of science and technology, the consumer very pays attention to its serviceability and comfort when selecting household electrical appliance.Known outlet open-type water storing type water heater is earlier the water in the water storage tank to be heated to predefined temperature when using, to make leaving water temperature reach the water requirement with the mixing ratio of hand adjustment thrift lock change hot and cold water during water, regulate the excursion of water temperature and change precision wayward.

The utility model content

The purpose of this utility model is to provide a kind of electronic temp regulator that hot and cold water water system water outlet water temperature is regulated that is applied to, to realize the Based Intelligent Control leaving water temperature.

For achieving the above object, solution of the present utility model is:

A kind of electronic temp regulator is applied to the hot and cold water water system, comprises controller, control circuit, motor and control valve; Control circuit receives the signal that controller sends, and the control motor rotates; Described control valve comprises valve body, adjusting rod, push rod, regulating sleeve and piston, valve body is provided with cold water inlet, water inlet of hot water and delivery port, adjusting rod is connected with motor, rotated by driven by motor, and push rod is positioned at the adjusting rod below, be threaded with adjusting rod, regulating sleeve is sheathed on push rod outward to the push rod rotary stopper, and push rod can only be moved vertically, and the push rod lower end cooperates with piston, piston is positioned at valve body, moves axially the relative water inlet area of regulating cold water inlet and water inlet of hot water.

Described piston up/down perforation, sidewall can cooperate with valve seal, and cold water inlet and water inlet of hot water are staggered up and down is located at body wall, and delivery port is positioned at the valve body bottom and is communicated with piston.

Described valve interior wall forms flange, and a back-moving spring lower end abutment is in flange, upper end abuts against plunger bottom.

Described motor is brshless DC motor or stepper motor.

Described controller is a control panel of being located at the water heater surface.

Described controller is a remote controller.

After adopting such scheme, the utility model can select temperature to raise or reduction by controller, control motor forward or reverse drives adjusting rod and rotates after the control circuit received signal, and adjusting rod is transmitted in push rod, because push rod is subjected to the regulating sleeve rotary stopper, can only rise vertically or descend, move vertically, regulate the relative water inlet area of cold water inlet and water inlet of hot water thereby drive piston, promptly regulate hot and cold water water inlet ratio, realize the function of intelligence adjusting water outlet water temperature thus.

Fig. 2 is piston Principles of Regulation figure;

Fig. 3 is an A-A schematic cross-section among Fig. 2.

The specific embodiment

As shown in Figure 1, be the schematic diagram of a preferred embodiment of the utility model.

A kind of electronic temp regulator that the utility model provides is applied to the hot and cold water water system, comprises controller 1, control circuit 2, motor 3 and control valve; Described controller 1 can be the control panel of being located at the water heater surface, also can be a remote controller; Control circuit 2 receives the signal that controller 1 sends, according to signal control motor 3 rotatings; Described motor can be brshless DC motor or stepper motor.

Described control valve comprises valve body 7, adjusting rod 4, push rod 5, regulating sleeve 8 and piston 6, valve body 7 is provided with cold water inlet 71, water inlet of hot water 72 and delivery port 73, be connected with the hot and cold water inlet pipeline and the outlet pipeline of water heater respectively, cold water inlet 71 and water inlet of hot water 72 are staggered up and down is located at valve body 7 sidewalls, delivery port 73 is positioned at valve body 7 bottoms, and valve body 7 inwalls form flange 74;

Adjusting rod 4 is connected with the rotating shaft 31 of motor 3, driven by motor 3 and rotates;

Push rod 5 is positioned at adjusting rod 4 belows, be threaded with adjusting rod 4, consult shown in Figure 2ly, adjusting rod 4 bottom bar bodies form external screw thread in the present embodiment, push rod 5 upper ends formation one has the cavity 51 of internal thread, and the adjusting rod 4 lower end bodies of rod stretch in the cavity 51 and are threaded with it;

Regulating sleeve 8 fixed covers are located at outside the push rod 5 and to push rod 5 and are played the rotary stopper effect, push rod 5 can only be moved vertically, consult shown in Figure 3ly, the cross section of push rod 5 is a hexagon in the present embodiment, regulating sleeve 8 forms the fixed in shape that cooperates with it and is sheathed on outside the push rod 5, and it can't be rotated;
