Description

TECHNICAL FIELD The present invention relates to the field of solar energy technology, and more particularly to a solar energy cold water circulation device.

With the advancement of science and technology and the improvement of people's living standards, solar water heaters have already been widely used in the homes of ordinary people. In general life, to use the hot water in the solar water heater, the cold water remaining in the water outlet pipe must first be discharged. Therefore, users not only have to wait for a certain period of time, but also waste water resources.

As is well known, the time when water was seen as an inexhaustible resource has already passed, and the water crisis is a harsh reality that today's society has no choice but to face. Taking an ordinary household as an example, if you use the solar water heater 5 times a day and waste 3 liters of water each time, the annual wasted water will exceed 5 cubic meters. leads to a large waste of water resources.

At present, the cold water treatment method in the drain pipe of the solar water heater is mainly to modify the solar water heater, which not only has a relatively high economic cost, but also has a relatively low cold water recovery efficiency. Reflux time cannot be felt intuitively.

Therefore, the solar energy cold water circulation device has become an urgent problem for people to solve.

SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a solar energy cold water circulation device with simple structure, easy operation, and intuitive visual temperature.

In order to solve the above technical problems, the present invention provides a cold water drain pipe at the water inlet end of the water heater mixing valve, a water valve switch at the connection between the cold water drain pipe and the water inlet, and the cold water Provided is a solar energy cold water circulation device with water heater mixing valve, characterized in that a solenoid valve is installed at the end of the drain pipe, and the solenoid valve is connected to an external power source through a wireless socket.

As an improvement, a thermometer is provided on the hot water pipe side of the water heater mixing valve, and the temperature probe of the thermometer extends into the hot water pipe.

The improvement further includes a wireless remote control, said wireless remote control engaging the wireless outlet.

Compared with the prior art, the present invention uses the water valve switch to control the opening and closing of the cold water drain pipe, and the remote control to remotely control the opening and closing of the solenoid valve, so as to achieve the purpose of cold water circulation, and the thermometer It has the advantage that the water temperature in the hot water pipe of the water heater mixing valve can be visually seen, the solenoid valve and the water valve switch can be closed in time, and the uncontrollable reflux time can be avoided.

Fig. 2 shows a structural schematic diagram of the solar energy cold water circulation device of the present invention;

Hereinafter, the solar energy cold water circulation device of the present invention will be described in more detail with reference to the drawings.

In order to describe the objects, technical solutions and advantages of the embodiments of the present invention more clearly, the following will describe the technical solutions of the present invention clearly and completely in combination with the drawings, and of course the described The examples are merely examples of the present invention and not all examples. The components of embodiments of the invention are generally described and illustrated in the accompanying drawings herein, and may be arranged and designed in a variety of different configurations.

Also, the terms "first", "second", and "third" are used only to distinguish the descriptions and should not be understood as indicating or implying relative importance. .

Also, when terms such as "horizontal", "vertical", "suspended" appear, it does not mean that the part requires absolute horizontal or suspension, but rather that it may be slightly slanted. That is. For example, "horizontal" simply means that the direction is more horizontal than "vertical", rather than implying that the structure must be perfectly horizontal. It can be slightly slanted.

In describing embodiments of the present invention, "plurality" means at least two.

In describing embodiments of the present invention, terms such as "installation", "attachment", "connection", "connection", etc. are to be understood broadly, unless otherwise defined. For example, it may be a fixed connection, a removable connection or an integral connection. It may be a mechanical connection or an electrical connection. It may be a direct connection, an indirect connection through an intermediate medium, or an internal connection of two parts. A person skilled in the art should understand the specific meaning of the above terms in the present invention according to the specific situation.

As shown in the drawing, a solar energy cold water circulation device with a water heater mixing valve 1, a cold water drain pipe 2 is provided at the water inlet end of the water heater mixing valve 1, and the cold water drain pipe 2 and A water valve switch 3 is provided at the connection with the water supply port, a solenoid valve 4 is provided at the end of the cold water drain pipe 2 , and the solenoid valve 4 is connected to an external power source via a wireless outlet 5 .

A thermometer 6 is provided on the hot water pipe side of the water heater mixing valve 1, and the temperature probe of the thermometer 6 extends into the hot water pipe.
