Utility model content
The purpose of this utility model is to provide a kind of water heaters preventing out cold water, to solve the above problems.
The utility model uses following technical solution:
A kind of water heater preventing out cold water, which is characterized in that including:Cold water retains case, and there are three openings for tool, respectively First opening, the second opening and third opening;Return pipe, first opening in communication of one end and cold water retention case are another End is connected with water inlet pipe;Hot-water line, one end are connected with the water tank of water heater, the other end and the second of cold water retention case Opening is connected;Outlet pipe retains the third opening in communication of case with the cold water;First temperature switch and second temperature are opened It closes, is arranged in the cold water retention case;Circulating pump is arranged on the return pipe;Solenoid valve is arranged in the outlet pipe On, first temperature switch is electrically connected with the circulating pump, and the second temperature switch is electrically connected with the solenoid valve.
Further, the water heater for preventing out cold water of the invention, also has the feature that:Wherein, first temperature Switch is connected when temperature is less than or equal to 40 DEG C, and circulating pump is opened, and first temperature switch is disconnected when temperature is more than 40 DEG C, Circulation pump, the second temperature switch are connected when temperature is more than 40 DEG C, and solenoid valve is opened, and the second temperature switch exists Temperature is less than or equal to disconnect at 40 DEG C, and solenoid valve is closed.
Further, the water heater for preventing out cold water of the invention, also has the feature that:Wherein, first temperature Switch is positioned close to the position of the second opening.
Further, the water heater for preventing out cold water of the invention, also has the feature that:Wherein, the second temperature Switch is positioned close to the position of third opening.
The advantageous effect of utility model
The water heater for preventing out cold water of the utility model retains case due to being provided with cold water, and is provided with two temperature 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 16 disconnect when temperature is more than 40 DEG C, and circulating pump 13 is closed.
Second temperature switch 17 is connected when temperature is more than 40 DEG C, and solenoid valve 19 is opened, and second temperature switch 17 is in temperature It is disconnected when less than or equal to 40 DEG C, solenoid valve 19 is closed.
Prevent out the course of work of the water heater of cold water as follows:
After the hot water in boiler is burned, the tap of hot water is opened out, flow flows to cold water from hot-water line 15 and cuts at this time It stays in case 18, the first temperature switch 16 detects the temperature of flow, and what is flowed at the beginning is colder water, when temperature is less than or equal to 40 DEG C when the first temperature switch 16 in an ON state so that circulating pump 13 is opened, and solenoid valve 19 is closed at this time, water Stream is flow back into from return pipe 12 in water tank 14.After the hot water in water tank 14 is flowed into cold water retention case 18, on water flow temperature It rises.When water flow temperature rises to 40 DEG C or more, the first temperature switch 16 disconnects, and second temperature switch 17 is connected, solenoid valve 19 It opens, temperature is flowed to higher than 40 DEG C in tap at this time, for a person to use.
The water heater for preventing out cold water of the utility model retains case due to being provided with cold water, and is provided with two temperature 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.
