Description

Supercharged solar water heater water storage tank and solar water heater

Technical Field

The utility model relates to the technical field of photo-thermal equipment, in particular to a supercharged solar water heater water storage tank and a solar water heater.

Background

The solar water heater is a heating device for converting solar energy into heat energy, and heats water from low temperature to high temperature so as to meet the requirement of hot water in life and production of people. The solar water heater is divided into a vacuum tube type solar water heater and a flat plate type solar water heater according to the structural form, mainly the vacuum tube type solar water heater occupies 95% of the domestic market share. The vacuum pipe type domestic solar water heater is formed from heat-collecting pipe, water-storing tank and supporting frame, etc. and is used for converting solar energy into heat energy, and the vacuum heat-collecting pipe can utilize the principle of hot water floating up and cold water sinking down to make water produce microcirculation so as to obtain the required hot water.

The water storage tank is a container for storing hot water by solar energy. The hot water collected by the heat collecting pipe must be stored by the heat preservation water tank to prevent heat loss. The solar water heater used in the market at present is mainly divided into pressure-bearing type and non-pressure-bearing type, while the common solar water heater belongs to the non-pressure-bearing type water heater, and a water tank of the common solar water heater is provided with a pipe which is communicated with an end user, and the pressure is generated by the gravity of water when the common solar water heater is used by utilizing the height fall of a roof and an indoor water outlet end.

However, compared with the pressure-bearing solar water heater, the water supply mode of the non-pressure-bearing solar water heater has the advantages of smaller water outlet pressure and poorer use comfort, and particularly has poor use experience in places with smaller height differences such as low self-building houses or old communities in some rural areas, and the use effect is reduced because the water storage tank is communicated with the atmosphere, and heat can be continuously dissipated.

Therefore, how to obtain a solar water heater water tank with simple structure and supercharging effect is the problem to be solved by the application.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a supercharged solar water heater water storage tank with a simple structure and a solar water heater, which can automatically seal the water tank along with the rise of water temperature and isolate the water tank from being communicated with the atmosphere so as to realize the supercharging effect.

The technical scheme for solving the technical problems is as follows:

on one hand, the utility model provides a supercharged solar water heater water storage tank, which comprises a water tank body, wherein the upper part of the water tank body is connected with an overflow pipe, the inner end of the overflow pipe is communicated with the inner cavity of the water tank body, and the outer end of the overflow pipe is communicated with the outside.

Further, the air bag is fixedly connected with the pipe wall of the overflow pipe.

Further, the outer wall of the air bag is fixedly connected with a rope, and the air bag is fixedly connected with the pipe wall of the overflow pipe through the rope.

Further, a stop lever is arranged at the inner end of the overflow pipe.

Further, the outer wall of the air bag is made of heat-resistant rubber.

Further, the outer diameter of the air bag is smaller than the caliber of the inner port of the overflow pipe in the initial state; when the water temperature of the water tank body reaches the preset temperature, the air bag is heated and expanded until the outer wall of the air bag is in contact with the inner wall of the overflow pipe.

Further, the side wall of the upper part of the water tank body is also connected with a pressure release valve.

In another aspect, the utility model provides a solar water heater characterized by comprising a pressurized solar water heater storage tank as described above.

The beneficial effects of the utility model are as follows: according to the utility model, through the airbag structure arranged at the specific position of the overflow pipe, when the water temperature of the water tank body reaches the preset temperature, the airbag is heated and expanded until the outer wall of the airbag is in contact with the inner wall of the overflow pipe, so that a closed space is formed by the water tank body, the internal pressure of the closed space is increased along with the increase of the water temperature, and the water outlet pressure at the tail end is increased; the closed space formed by the air bag after expansion can also ensure that the water quality in the water storage tank is not polluted by winged insects and the like. In addition, the pressure release valve that sets up can guarantee the inside upper limit of pressure of storage water tank, provides the safety guarantee.
