Abstract
The utility model belongs to the technical field of solar hot water utilization and particularly relates to a solar hot water utilization system. The solar hot water utilization system comprises a solar heater and an indoor water utilization appliance, wherein a hot water outlet of the solar heater is connected with the indoor water utilization appliance by a hot water pipe; a water outlet of the hot water pipe is connected to a water inlet of the solar heater by a circulation line; the circulation line is provided with a circulation pump which is controlled by a delay device. The starting of the circulation pump is controlled by the delay device; when hot water is used, after water in the hot water pipe, i.e., water in the hot water pipe between the solar heater and a water utilization point, is input to the solar heater through starting the circulation line by the delay device, a hot water valve is opened and the hot water can be used; waste caused by evacuation of cold water stored in the hot water pipe is prevented, the requirement on hot water utilization of a user can be ensured, and thus the problem that water resource waste is caused due to the fact that the water in the water pipe between the outdoor solar heater and the water utilization point needs to be discharged when the hot water is used at present is solved.
Description
Technical field
The utility model belongs to solar water and utilizes technical field, is specifically related to a kind of solar heat water utilization system.
Background technology
At present, household solar water heater, because system is simple, conventionally be not with EGR, so that user needs the outdoor solar water heater of emptying to the water with in water pipe between water spot, just can go out hot water, caused so certain water resource waste, particularly at some solar water heaters, be placed in roof, and the lower user of user's floor, in the pipe that must emit to retain cold water just more, although this part water can hold with utensil, for purposes such as doing washing, mop floor, but this using method is also made troubles to user.
Utility model content
The purpose of this utility model is to overcome above-mentioned prior art problem and a kind of solar heat water utilization system is provided, and be intended to solve needs the outdoor solar water heater of emptying to retaining cold water to such an extent as to caused the technical problem of certain water resource waste in water pipe between with water spot when using hot water.
For achieving the above object, the utility model adopts following technical scheme:
A kind of solar heat water utilization system, comprise the indoor water appliance that the hot water outlet of solar water heater and described solar water heater is connected by hot-water line, the delivery port of described hot-water line connects the water inlet of described solar water heater by circulation line, described circulation line is provided with the circulating pump of being controlled by time-delay mechanism.
Described time-delay mechanism is located at a side of described indoor water appliance.
Described circulation line is provided with check valve, and described check valve is located at water side one side of described circulating pump.
The utility model is opened by time-delay mechanism controlled circulation pump, by the water in hot-water line, be that solar water heater is to opening hot water valve use hot water with retaining after cold water is inputted solar water heater in hot-water line between water spot again, prevented that the discharge that retains cold water in emptying hot-water line from causing waste, also guarantee the needs that user uses hot water, thereby solved, when using hot water, needed at present emptying outdoor solar water heater to retaining cold water to such an extent as to caused the technical problem of certain water resource waste in water pipe between with water spot.
Accompanying drawing explanation
Figure 1 shows that the structural representation of a kind of solar heat water utilization system that the utility model embodiment provides.
The specific embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Shown in Figure 1, the figure shows the structure of a kind of solar heat water utilization system that the utility model embodiment provides.For convenience of explanation, only show the part relevant with the utility model embodiment.
Refer to Fig. 1, a kind of solar heat water utilization system, comprise the indoor water appliance 2 that the hot water outlet of solar water heater 1 and described solar water heater 1 is connected by hot-water line 3, as shower facilities, the delivery port of described hot-water line 3 connects the water inlet of described solar water heater 1 by circulation line 4, described circulation line 4 is provided with the circulating pump 5 of being controlled by time-delay mechanism 7.
Described circulating pump 5 adopts low profile thermal water-circulating pump, and flow is 2m
3/ h, lift is 2mH
2o, power consumption 200w left and right.By computation cycles pump work, can make the hot-water line of whole connection solar water heater and indoor water appliance be full of hot water 10 seconds, can save the cold water 5～8L in the hot-water line bleeding off.Because each working time is short, each circulating pump is power consumption 0.0005 degree only, and 1 degree electricity can make water pump complete circulation 2000 times.
In the utility model embodiment, the circulation pipe of described circulation line 4 can adopt DN15 aluminium-plastic pipe to make.
Further, described circulation line 4 is provided with check valve 6, and described check valve 6 is located at water side one side of described circulating pump 5.
Further, described time-delay mechanism 7 is located near the dry point of a side of described indoor water appliance 2.
The utility model is by the unlatching of time-delay mechanism controlled circulation pump, use hot water front by the water in hot-water line, be that solar water heater is to opening hot water valve use hot water with retaining after cold water is inputted solar water heater in hot-water line between water spot again, prevented that the discharge that retains cold water in emptying hot-water line from causing waste, also guarantee the needs that user uses hot water, thereby solved, when using hot water, needed at present emptying outdoor solar water heater to retaining cold water to such an extent as to caused the technical problem of certain water resource waste in water pipe between with water spot.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
