Abstract
The utility model discloses a kind of hot water supply system, form primarily of water heater, water supply line, reflux line, cold water pipes, pump and tap, it is characterized in that: water heater is communicated with reflux line with water supply line, tap, pump successively, reflux line is communicated with cold water pipes and is finally compiled in water heater, forms a waterway circulating; Described tap is screw down nonreturn valve, and be communicated with water supply line and reflux line when it is closed, block connection when opening, current can only be flowed out by tap outlet.The utility model just can obtain optimum water temperature immediately after tap of fetching boiling water, and go to regulate water temperature without staff, can not run off unnecessary water in vain, saves water resource.The utility model may be used for domestic hot water systems or hotel hot-water heating system etc.
Description
Technical field
The utility model relates to water system, especially a kind of hot water supply system that can provide preference temperature.
Background technology
Pot-type boiler is each family hot-water supply, is the source of domestic hot water, to have a bath use for bathroom, or for kitchen wash dish with etc.Before acquisition hot water, first need first the cold water emptying in pipeline to be supplemented hot water simultaneously, because cold water can not be applicable to have a bath or wash dish, therefore can not obtain comparatively good utilisation, generally just run off in vain.
On the other hand, before acquisition hot water arrives, owing to also needing preheating pipe, along with cold water runs off, water temperature also constantly raises, and when people remove touching water, is not probably optimum water temperature, therefore also need to regulate water temperature, increase cold water or hot water etc., waste water resource further.
Summary of the invention
In order to solve the problem, the utility model provides a kind of hot water supply system, and just can obtain suitable water temperature after tap of fetching boiling water, need not regulate water temperature, save time, also can not run off cold water, waste water resource.
The technical scheme in the invention for solving the technical problem is:
A kind of hot water supply system, form primarily of water heater, water supply line, reflux line, cold water pipes, pump and tap, its annexation is that water heater is communicated with reflux line with water supply line, tap, pump successively, reflux line is communicated with cold water pipes and is finally compiled in water heater, forms a waterway circulating; Described tap is screw down nonreturn valve, and be communicated with water supply line and reflux line when it is closed, block connection when opening, current can only be flowed out by tap outlet.
Described water heater forms primarily of heating part, containment portion and lower water temperature part.
During use, before water temperature does not reach predetermined temperature, current are back to water heater containment portion again through tap and continue heating; After water temperature reaches preset range temperature, stop waterway circulating, water (flow) direction is to tap one-way flow by water heater.
Described tap can be also automatically controlled screw down nonreturn valve, before water temperature does not reach predetermined temperature, and controller auto-closed water tap, when water temperature to reach after predetermined temperature and in the reasonable scope time, automatically to fetch boiling water tap, when temperature is higher than dangerous values, then auto-closed water tap.
The effect of described pump is by waterflow boosting, and then ensures that current are back to water heater again.
The water temperature of described lower water temperature part is set to general human body sense optimal temperature.
Described tap according to actual needs, can be shower faucet or Kitchen tap.
The beneficial effects of the utility model are,
The utility model just can obtain optimum water temperature immediately after tap of fetching boiling water, and go to regulate water temperature without staff, can not run off unnecessary water in vain, saves water resource.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model channel circulation structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is further described.
As shown in Figure 1, the utility model forms primarily of water heater 1, water supply line 2, reflux line 3, tap 4, cold water pipes 5 and pump 6.Described water heater forms primarily of heating part, containment portion and lower water temperature part.Cold water pipes adds water to containment portion always, set predetermined thermal coolant-temperature gage when the lower water temperature button pressed on lower water-heater, now heater starts to the water heating in water receiver, now tap is in closed condition, water supply line is communicated with reflux line, now pump is in running order, and water (flow) direction is that in water receiver, water is back to water receiver inside again through tap;
When water temperature reaches predetermined temperature and in optimum range, water heater provides prompt tone, remind user's water temperature suitable, now user fetches boiling water tap, water supply line and reflux line cut-off, closed by pump, water (flow) direction is that water heater flows to tap simultaneously.
Another embodiment of the utility model is: the utility model is applied to hotel, itself and domestic hot water's supply system difference be, hotel adopts central heating mode, hot water is stored in storage tank, and the tap opening each room just can obtain hot water immediately, and this water temperature of ordinary circumstance is higher than human body sense optimum temperature, in order to regulate water temperature, need rotary faucet valve handle, increase cold water, mix with the hot water of higher temperature the water obtaining optimum temperature like this.
In order to avoid water resource waste, the thinking that such scheme is identical can be adopted, increase reflux line, and tap is replaced to screw down nonreturn valve, the water being not suitable for temperature is back in storage tank again, after tap of fetching boiling water like this, obtain the hot water of optimal temperature.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model cover fall into appending claims and equivalent thereof scope in various remodeling and change.
