Degree switch so that in cold-water reflux to water tank, only when temperature is higher than scheduled temperature, hot water could flow out.On the one hand anti-
Go out the discomfort that cold water causes user after only opening tap, on the other hand, the one section of cold water started in water pipe turns again to water
It is heated in case, decreases the waste to water.
Description of the drawings
Fig. 1 is the overall structure diagram of the water heater for preventing out cold water of the utility model.
Specific implementation mode
Illustrate specific embodiment of the present utility model below in conjunction with attached drawing.
As shown in Figure 1, preventing out the water heater of cold water from including:Cold water retains case 18, return pipe 12, hot-water line 15, water outlet
Pipe 20, the first temperature switch 16, second temperature switch 17, circulating pump 13 and solenoid valve 19.
Cold water retains case 18, and there are three opening, respectively first the 21, second opening 22 of opening and third openings 23 for tool.
Return pipe 12, the first opening 21 that one end retains case 18 with cold water are connected, and the other end is connected with water inlet pipe 11.
Hot-water line 15, one end are connected with the water tank 14 of water heater, the second opening 22 of the other end and cold water retention case 18
It is connected.
Outlet pipe 20, the third opening 23 that case 18 is retained with cold water retention case cold water are connected.
First temperature switch 16 and second temperature switch 17 are arranged in cold water retention case 18;First temperature is opened
Close the position for being positioned close to the second opening.Second temperature switch is positioned close to the position of third opening.Temperature switch is one
Bimetal leaf kind is used to be used as the temperature switch of temperature-sensing element, when electric appliance normal work, bimetal leaf is in free state, at contact
In closure/off-state, when temperature is increased to operating temperature value, bimetallic element is heated to be generated internal stress and acts rapidly,
Opened/closed contact, is switched off/on circuit, to play heat protective effect.When temperature, which drops to, resets temperature, contact is closed automatically
Conjunction/disconnection restores normal operating conditions.It is widely used in domestic electric appliance motor and electrical equipment, such as motor for washer, air-conditioning fan
Motor, transformer, ballast, electric heating appliance etc..
Circulating pump 13 is arranged on return pipe 12.Solenoid valve 19 be arranged on outlet pipe 20, the first temperature switch 16 with follow
13 electrical connection of ring pump, second temperature switch 17 are electrically connected with solenoid valve 19.The circuit that temperature switch controls solenoid valve is this field
Common circuit, details are not described herein again.
Wherein, the first temperature switch 16 is connected when temperature is less than or equal to 40 DEG C, and circulating pump 13 is opened, the first temperature switch
