Multi-inner container solar water heater

Abstract

The invention provides a solar water heater with a plurality of inner liners, mainly consisting of a water storing tank, a heat collecting device and a bracket. The water storing tank and the heat collecting device are both arranged on the bracket. The water storing tank mainly comprises an outer casing, an insulation material, inner liners, a water feeding pipe and a water draining pipe. The number of the inner liners is at least two, and all the inner liners are horizontally arranged and sequentially communicated together. The water feeding pipe is communicated with the first inner liner, the water draining pipe is communicated with the last inner liner, and a floating water-taking pipe is arranged at the pipe end of the water draining pipe in the last inner liner. The solar water heater is characterized in that the water feeding pipe is communicated with the inner-lower part or the bottom of the first inner liner; except for the first inner liner, all inner liners are provided with a heat collecting device and communicated with the inner-upper parts or the top parts of the heat collecting devices; the heat collecting device can be in plate style or heat collecting tube style. The first inner liner of the invention is communicated and storied with tap water and provided with no heat collecting device; the stored water in the first inner liner can be used as spare cold water to be combined with the hot water in other inner liners for bathing when no tap water is supplied. The solar water heater has more beautiful appearance and the communication with external pipelines is simpler.

Description

Technical field [0001] The invention relates to the field of solar water heating, in particular to a multi-tank solar water heater. Background technique [0002] Currently commonly used solar water heaters are exposed to sunlight for a long time, and the water stored in the water tank will reach a very high temperature. When bathing, it must be mixed with tap water to obtain hot water at a suitable temperature. Once the tap water is cut off, it is impossible to bathe. In areas where there is no tap water or tap water cannot be supplied normally, people often install an auxiliary water tank to store cold water. When there is no tap water, the cold water in the auxiliary water tank and the hot water in the solar water heater are mixed for bathing. The auxiliary water tank often requires a special support , takes up a lot of space, and is not beautiful enough, the auxiliary water tank and the water tank of the solar water heater need to be connected with the tap water pipeline,...

[0002] Currently commonly used solar water heaters are exposed to sunlight for a long time, and the water stored in the water tank will reach a very high temperature. When bathing, it must be mixed with tap water to obtain hot water at a suitable temperature. Once the tap water is cut off, it is impossible to bathe. In areas where there is no tap water or tap water cannot be supplied normally, people often install an auxiliary water tank to store cold water. When there is no tap water, the cold water in the auxiliary water tank and the hot water in the solar water heater are mixed for bathing. The auxiliary water tank often requires a special support , takes up a lot of space, and is not beautiful enough. Both the auxiliary water tank and the water tank of the solar water heater need to be connected with the tap water pipeline, and the pipeline layout is complicated.

[0003] In the commonly used heat collecting tube solar water heater, the heat collecting tube is directly inserted on the water tank of the water heater, and there is a gap between the heat collecting tube and the jack at the water tank jack, where heat loss will occur
