Abstract

The utility model relates to a water tank type household solar water heater, which can absorb solar energy and can store heat. The utility model is composed of heat collectors, a water inlet and outlet pipe, a draining air pipe, and a heat storage box. The utility model is characterized in that the heat storage box is a sealing structure whose lighting surface is double glass; a housing body is provided with a heat-insulating layer and a sealing body; the heat collectors are connected with each other in parallel in the heat storage box, so the lighting area is enlarged, and the heat-insulating time is extended. The utility model has the advantages of compact structure, small size, low cost, high heat efficiency, convenient installation, etc.

Description

The water tank type domestic solar water heater

The utility model relates to a kind of solar water heater, particularly a kind ofly not only can absorb solar energy but also water tank type domestic solar water heater that can store heat.

At present, solar water heater can be divided into two kinds, a kind of water heater of the natural recirculating type system that forms by water heater, water tank, circulating line, though that this water heater is worked is reliable, thermal efficiency height, but systematic comparison complexity, bulky, floor space is big, the cost height, difficulty is installed in transportation, is not suitable for family and uses; Another kind is a shallow pond simmering shining type solar water heater, though this water heater simple structure, volume is less, is convenient to family and installs and uses, and cost is also lower, and the thermal efficiency is low, during bad weather, can not provide hot water.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of improved water tank type domestic solar water heater is provided, and it is thermal efficiency height not only, and volume is little, in light weight, cost is low, be easy to installation, is particularly suitable for family and uses.

The purpose of this utility model is achieved in that this water tank type domestic solar water heater, by heat collector, water inlet pipe and water outlet pipe, the sluicing tracheae, storing hot case forms, the housing of storing hot case is made of the heat-insulation layer that inner plating and lamina rara externa wrap up, the daylighting face of storing hot case constitutes the double glazing hermetically-sealed construction by inner layer glass and glass outer, make the hot case of storage become seal, heat collector one end of storing in the hot case communicates with water inlet pipe and water outlet pipe, the other end communicates with the sluicing tracheae, become parallel structure, the water inlet pipe and water outlet pipe of storing the sluicing tracheae of hot case internal upper part and bottom passes the hot case shell wall of storage and goes out.In order fully to absorb luminous energy, store the inside and outside two finish paint adularescent layers of hot tank shell lamina rara externa, inner plating appearance finish paint has black layer, and the heat collector surface lacquer of storing in the hot case has black layer.

The utility model is because the heat collector that is filled with water is installed in the sealing with heat-insulation layer housing to be store in the hot case, and heat scatters and disappears few, in addition, owing to adopt a plurality of heat collector parallel connections, increased daylighting area, so thermal efficiency height, and this simple in structure, volume is little, cost is low, install and use easily.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the structural representation according to the water tank type domestic solar water heater who the utility model proposes.

Fig. 2 is the A-A face cutaway view of the utility model Fig. 1.

Fig. 3 is the B-B face cutaway view of the utility model Fig. 1.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete structure that the utility model proposes.

As accompanying drawing 1～shown in Figure 3, this water tank type domestic solar water heater, by heat collector (5), water inlet pipe and water outlet pipe (4), sluicing tracheae (7), storing hot case (11) forms, heat collector length=1000mm wherein, diameter=120mm, store overall dimensions length * wide * height=1300 * 980 * 200mm of hot case, storing the housing of hot case (11) is made by the heat-insulation layer (16) of inner fiber plate (12) and outer galvanized iron sheet (13) parcel, make the insulation material of heat-insulation layer (16) with cotton-wool, in order fully to absorb solar energy, the appearance finish paint of inner fiber plate (12) has pitch-dark layer, the white paint layer has all been coated with lacquer on the inside and outside two sides of outer galvanized iron sheet (13), the daylighting face of storing hot case (11) constitutes the double glazing hermetically-sealed construction by inner layer glass (10) and glass outer (9), make the hot case of storage (11) become seal, the bottom surface of storing in the hot case (11) is provided with the support (15) that supports inner layer glass (10), the upper surface of inner layer glass (10) is provided with the little magnetic patch (14) that supports glass outer (9), store hot case (11) four jiaos, be provided with the stop intermediate plate (8) that prevents that glass outer (9) from sliding, store and be provided with five columnar heat collectors of making of galvanized iron sheet (5) in the hot case (11), heat collector (5) is fixed on the housing of the hot case of storage with iron hoop (6), each heat collector (5) one end communicates with water inlet pipe and water outlet pipe (4), the other end communicates with sluicing tracheae (7), become parallel structure, the appearance finish paint of each heat collector (5) has pitch-dark layer, and the water inlet pipe and water outlet pipe (4) of storing the sluicing tracheae (7) of hot case (11) internal upper part and bottom passes to be store hot case shell wall and go out.

When this water tank type domestic solar water heater uses, water inlet pipe and water outlet pipe (4) is connected with running water pipe, running water pipe is provided with gate valve (3), water meter (2), and other is provided with the water valve (1) that a control hot water flows out.During work, close water supply valve (1), open gate valve (3), flow through gate valve (3), water meter (2), water inlet pipe and water outlet pipe (4) of running water enters in each heat collector (5), and the reading from water meter (2) is determined closing gate valve (3).Sunlight sees through layer glass (9) and (10), shines on each heat collector (5) that is sprayed with pitch-dark layer, shines the heat energy on heat collector (5), has been absorbed by the water in the heat collector (5), above warm current direction; The heat energy of solarization in heat-insulation layer. warm heat collector (5), having been absorbed by the water in heat collector (5) back side, the higher water of temperature also just flows to the top, and so circulation goes round and begins again, and the water temperature in the heat collector (5) is just step by step improve also.Because the effect of the hot case of sealed storage (11) only allows light and heat energy to enter, the heat energy that ease sends out seldom can keep the long time so store the water temperature of the interior heat collector of hot case (11) (5) lining.When needing to use hot water, open water valve (1), hot water has just flowed out.
