Solar water heater

Abstract

The invention discloses a solar water heater. The solar water heater comprises an overflow opening, a water inlet, a water tank, an insulation layer, vacuum tubes, a plastic holder, a transverse supporting frame, a main supporting frame and a base. The overflow opening and the water inlet are arranged in the same side of the water tank, the overflow opening is arranged in the top of the side of the water tank, and the water inlet is arranged in the bottom of the side of the water tank. The insulation layer comprises a housing, an insulation material and an interior from outside to inside. The two groups of vacuum tubes are symmetrically arranged relative to the main supporting frame. The transverse supporting frame is connected to the vacuum tubes and the central portion of the main supporting frame and suspended at an obtuse angle. The base is connected to the vacuum tubes and the bottom of the main supporting frame and horizontally arranged to the ground. The plastic holder is arranged at the bottoms of the vacuum tubes. The solar water heater is reasonable in design and simple in structure, still has a low-carbon environment-friendly function, prolongs direct sun lighting time and improves the heating efficiency.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a solar water heater. Background technique [0002] At present, the solar water heater in the prior art is basically a water tank equipped with a group of vacuum tubes, which is heated solely by solar energy. Recently, for the situation that solar energy cannot provide enough hot water in cloudy days, a water heater equipped with two water tanks has been improved and used. On the one hand, the water tank is to solve the problem of increasing the water capacity when the sun is sufficient, and on the other hand, it is also hoped that one of the water tanks can be heated by electricity to achieve hot water in cloudy days. The patent number is CN201220063699.2, which discloses a fast heating The energy-saving solar water heater water tank is two inner water tanks that are not completely separated, which solves the above problems, but we all know that the reason why solar water heaters a...

Problems solved by technology

[0002] At present, solar water heaters in the prior art are basically a water tank equipped with a set of vacuum tubes, relying solely on solar energy for heating, and recently relying on solar energy cannot provide enough hot water for cloudy days In this case, improve the use of a water heater equipped with two water tanks. On the one hand, the two water tanks are to solve the problem of increasing the water capacity when the sun is sufficient. The purpose, the patent number is CN201220063699.2 discloses a kind of fast heating and energy-saving solar water heater water tank, which is two inner water tanks that are not completely separated, which solves the above-mentioned problems, but we all know that the reason why solar water heaters are so common is that Because it relies on the energy of the sun, it is a very environmentally friendly and low-carbon device. If the solar water heater is also made into an electric heating form, it seems to solve the problem of no hot water on cloudy days. In this way, the solar water heater and ordinary household What is the difference between electric water heaters? They all need to rely on electricity consumption for heating, and solar water heaters are placed outside. Every day, the wind, rain, and sun exposure are not safe for the circuit. Especially in the weather of thunder and lightning, it is very easy to cause safety accidents.
