Abstract

The utility model discloses an automatic feeding solar water heater with good performance. The automatic feeding solar water heater is suitable for families and is used for being provided with a solar energy hot water shower system. Because the hot water output pipe of the utility model is arranged at the top of a thermal storage tank whose water level is the highest, and a cold water replenishing pipe is arranged at the bottom of a collecting heat tank whose water level is the lowest, the same valve can control the output to hot water and the replenishment for cold water. When people take a shower, the temperature of water can be regulated. During the process that the hot water is exhausted, because the temperature of water gradually descends, people can not feel discomfortable.

Description

Automatic water feeding solar water heater

The utility model relates to a kind of automatic water supplement solar water heater of function admirable, and it is fit to family and is used to install the solar hot-water bath system.

A solar water heater is installed is used for bathing, it is family's a kind of small investment of utilizing solar energy, effective, be worthy to be popularized, the implementation method that is easy to popularize, existing solar hot-water bath device, in use regular meeting runs into such problem: when 1, thinking bathing, but find because of forgetting that in advance adding water does not have hot water usefulness; 2, unexpected no hot water in the bathing, soapsuds all over the body have to dash with cold water, because of the temperature difference is too big, easily causes flu; 3, because of to when adding water, adding how much feeling unsure of, the excessive or phenomenon of topped up with water not of dilutional hyponatremia can appear adding; Very inconvenient, if install machinery or electronic director additional, not only increased cost and installation difficulty.And in practicality unless you give your whole attention to it, still the problems referred to above can take place.

The purpose of this utility model provides a kind of new-type automatic water supplement solar water heater, and it need not increase parts, just can satisfactorily resolve the problem of above-mentioned existence.New-type solar water heater mainly is the position that has changed inlet tube and outlet tube.That is: the water inlet pipe position is located at the minimum heat-collecting box bottom of water level, and the outlet pipe position is located at the highest heat storage tank top of water level.Replenishing of the output of hot water and cold water by same valve control.

Below with reference to accompanying drawing, the utility model is done detailed description.

With reference to Fig. 1, heat-collecting box (1) is by surperficial coating black, the board-like closed container that is provided with water inlet pipe and water outlet pipe with have the incubator that heat absorption heat-insulating property, front be equipped with glass plate and constitute.Heat storage tank (2) is to be provided with recirculated water into and out of pipe by middle part, bottom, and the top is provided with hot water delivery pipe's closed container and the heat absorption incubator of outer cover constitutes.With hot-water circulation pipe (3), cool water circulating pipe (4), heat-collecting box (1) heat storage tank (2) is connected into the closed loop.Open inlet valve (7) running water and just can give whole water heater topped up with water, cold water in the heat-collecting box is accepted to understand the intensification heating behind the solar energy, hot water is little because of proportion, can rising into through hot-water circulation pipe (3), its bottom, installation site is higher than in the heat storage tank (2) at heat-collecting box (1) top, simultaneously, cold water in the heat storage tank (2) sinks, replenish into through cool water circulating pipe (4) and to be heated in the heat-collecting box (1), so constantly circulation, just can make the cold water in the whole water heater become hot water, water volume after being heated expands, and the water that has more can be by hot water delivery pipe (5), shower nozzle (6) overflows, thereby the bad heat-collecting box (1) that expands can not take place, the phenomenon of heat storage tank (2).

During bathing, as long as open inlet valve (7), just have the hot water ejection in the shower nozzle (6), simultaneously, running water also covers in the water heater automatically, because the cold water that has just covered is than great, it can only from bottom to top eject hot water, phenomenon cold water can not appear last in, first out " offside ", and during bathing, high if the temperature of hot water is disliked, can open temp regulation valve (8) and inlet valve (7) fit adjustment hot water or cold water's ratio, just can make water temperature suitable, as long as tap water supply is normal, it is full and the phenomenon of cutting off the water supply can not occur just can to guarantee that water heater remains water.In addition, use the light time soon when hot water, the temperature of water reduces gradually, can not make under the weather.

Claims (2)

1, a kind of automatic water supplement solar water heater, form by heat-collecting box, heat storage tank, circulation pipe, control valve, shower nozzle, it is characterized in that hot water delivery pipe (5) is arranged on the top of the highest heat storage tank of water level (2), cold water replenishes pipe (9) device in the bottom of the minimum heat-collecting box of water level (1), and Inlet and outlet water is controlled by same valve (7).

2, automatic water supplement solar water heater according to claim 1 is characterized in that being equipped with temperature adjustment by-pass valve control (8).
