Problems solved by technology

[0011] ①It cannot be used without running water;
[0012] ②When the water temperature is not high, it is easy to cause waste every time the cold water used for top pressure returns in winter;
[0013] ③ It is inconvenient to use at multiple points. When using water at the same time, you should manually cut off the electric heating power supply
[0016] Disadvantages: It does not solve the problem of wasting hot water in pipes, and it is necessary to ensure smooth indoor exhaust
[0019] Disadvantages: Cannot be used with automatic water supply controller
[0022] Disadvantages: Because the control valve is located in the lower part of the water tank, it is easily polluted by scale, which leads to control failure and poor reliability; and because the valve body often retains water, it is necessary to add electrical insulation measures in winter
It cannot be used when there is a "U"-shaped bend pipe in the user's room; it cannot be filled and discharged when the power is off; if you forget to empty it after using hot water or water, freezing will occur

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings:

[0036] like figure 1 The shown automatic emptying device for the upper water pipe includes an upper water pipe 4 and an emptying valve 9 installed in the upper water pipe. The emptying valve 9 includes an upper fixing rod 10, a lower fixing rod 11, and a central axis. 12. The propeller 13, the spring 14, the blocking piece 15, the blocking piece limit stop 16 and the blocking piece connecting rod 17. The upper water pipe 4 is integrally formed with a shower port 18, and the inner wall of the upper water pipe on the lower side of the shower port 18 is integrally formed. A blocking piece limit stop 16 is installed, an upper fixing rod 10 and a lower fixing rod 11 are installed in the upper water pipe, and a central shaft 12 is connected between the upper fixing rod 10 and the lower fixing rod 11, and the central shaft The lower end of 12 is sleeved with the propeller 13...

Abstract

The invention provides an automatic water supply pipe emptier and a solar water heater provided with the automatic water supply pipe emptier. The automatic water supply pipe emptier comprises a drain valve and a water tank, wherein the drain valve comprises an upper fixing rod, a lower fixing rod, a center shaft, a propeller, a spring, a plug piece, a plug piece limit stop and a plug piece connecting rod; a water return pipe is arranged on one side of the top of the water tank; a water supply pipe is arranged at the bottom of the water tank; the top end of the water supply pipe is provided with a solenoid valve; the bottom end of the water supply pipe is provided with a water supply valve; the water supply pipe between the drain valve and the solenoid valve is provided with a connecting pipe; one end of the connecting pipe is communicated with the upper end of the water tank. The automatic water supply pipe emptier has the beneficial effects that the automatic water supply pipe emptier is simple, practical, low in manufacturing cost, convenient to mount, simple in structure, safe to use and easy to promote, and the water supply pipe can be prevented from being frozen off or cracked through a simple device; meanwhile, water cannot be remained after the water supply pipe supplies water, and the phenomenon that water resource is wasted by draining water before hot water is used is avoided.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to an automatic emptying device for an upper water pipe and a solar water heater having the device. Background technique [0002] Solar water heaters are energy-saving, environmentally friendly and safe, and are favored by the vast number of residents in our country. However, the severe cold weather in winter in the northern region will cause the inlet and outlet pipes of solar water heaters in many households to freeze. Residents are not only forced to replace the entire water pipe because of a small crack, but also affect the smooth flow of water. In addition, the cold water remaining in the water pipe must be discharged when using hot water at ordinary times, resulting in a great waste of water. This is the fly in the ointment of solar water heaters while facilitating the lives of residents. [0003] To overcome these deficiencies and optimize the performance of solar water h...
