Abstract
The invention discloses a water heater with a water returning function. The water heater comprises a water tank where hot water is stored, and further comprises a heater body and a water returning pump. A water returning pipe is arranged nearby a hot water inlet of the water tank. The water returning pipe is connected to the water tank after passing through the water returning pump and the heater body. The water heater can return the water stored in the water tank, thereby guaranteeing that water temperature is kept within a comfortable and usable range, enabling a user to use the hot water conveniently in daily life, and reducing waste of water resources.
Description
Technical field
The present invention relates to a kind of water heater with water return function.
Background technology
Because the hot water heating mode that existing storage-type electric water heater adopts can not be used immediately, need to be through heating up after a while, and store in advance a certain amount of hot water, therefore be provided with the attemperater that build is larger in water heater, while not using due to water heater after depositing for a long time, in water outlet of water tank water temperature around, still have decline by a relatively large margin, thereby award user, cause suitable inconvenience.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of water heater with water return function, avoid water temperature to decline.
The technical solution adopted for the present invention to solve the technical problems is:
A water heater with water return function, comprises the water tank of stored hot water, and water heater also comprises heater and back water pump, and the hot water outlet position annex of described water tank is provided with return pipe, and described return pipe is connected to water tank after described back water pump and heater.
As the improvement of technique scheme, described heater is arranged in described water tank, and described return pipe is connected to water tank after described back water pump.
A kind of improvement as technique scheme, described water tank is communicated with and is provided with for heating the thermal treatment zone of cold water and for the storage area of stored hot water, described heater is arranged in the described thermal treatment zone, described return pipe is arranged near the delivery port of described storage area, and return pipe is connected to the thermal treatment zone through described back water pump.
Another kind as technique scheme improves, described water tank is communicated with and is provided with for heating the thermal treatment zone of cold water and for the storage area of stored hot water, described return pipe is arranged near the delivery port of described storage area, and return pipe is connected to storage area through described back water pump and heater.
As the further improvement of technique scheme, the delivery port position of described water tank is provided with temperature sensor, and described temperature sensor is connected by central control module with water pump with described heater.
The invention has the beneficial effects as follows: this product can carry out backwater to the water storage in water tank, thereby guarantee that water temperature remains on comfortable available scope, facilitate user to use hot water in daily life, and reduce water resource waste.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of another embodiment of the present invention;
Fig. 3 is the structural representation of another embodiment of the present invention;
Fig. 4 is the structural representation of another embodiment of the present invention.
The specific embodiment
With reference to Fig. 1-4, a kind of water heater with water return function, it comprises the water tank 1 of stored hot water, water heater also comprises heater 2 and back water pump 3, the hot water outlet position annex of described water tank 1 is provided with return pipe 4, described return pipe 4 is connected to water tank 1 after described back water pump 3 and heater 2, water tank 1 volume is larger, fill with hot water in water tank 1 after, just easily there is heat exchange with the external world in the water inlet of nearly water tank 1 and near hot water delivery port, along with passage of time, water temperature just can progressively decline, while using water heater after the each water temperature of user runs off, always can first emit colder water storage, to people, brought much inconvenience for this reason, by back water pump 3, near the water that water tank 1 delivery port, water temperature declines to a great extent is drawn back to heater 2 and reheated intensification, then be back in water tank 1, thereby guarantee user to use water heater at any time and the cold water impact of can not lowering the temperature, facilitate routine use.
Improvement as above-mentioned embodiment, described heater 2 is arranged in described water tank 1, described return pipe 4 is connected to water tank 1 after described back water pump 3, because current most of storage-type electric water heater all carries out heating steps in water tank 1, water tank 1 first injects cold water, by the interior heater of establishing 2, carry out heat temperature raising again, after near water temperature water tank 1 delivery port declines, as long as utilizing water pump 3 draws back water storage to the position of heater 2 water tank 1 and re-starts heating from return pipe 4, thereby have when effectively keeping water temperature, can reduce costs, reduce and consume.
A kind of improvement as above-mentioned embodiment, described water tank 1 is communicated with and is provided with for heating the thermal treatment zone 5 of cold water and for the storage area 6 of stored hot water, current enter in storage area 6 again and are incubated and use after heating up from the described thermal treatment zone 5, this water tank 1 is generally applied in the water heater of electrothermal heating, to improve the electric heating efficiency of heating surface; Described heater 2 is arranged in the described thermal treatment zone 5, and described return pipe 4 is arranged near 6 delivery ports of described storage area, and return pipe 4 is connected to the thermal treatment zone 5 through described back water pump 3, temperature lowering water is drawn back again to the thermal treatment zone to 5 and heat.
Another kind as above-mentioned embodiment improves, described water tank 1 is communicated with and is provided with for heating the thermal treatment zone 5 of cold water and for the storage area 6 of stored hot water, described return pipe 4 is arranged near 6 delivery ports of described storage area, return pipe 4 is connected to storage area 6 through described back water pump 3 and heater 2, back water pump 3 is drawn to heater 2 by temperature lowering water through return pipe 4 and carries out Heat preservation processing, heat temperature raising work is carried out in a heater 2 conducts independently insulation thermal source, effectively reduce power consumption output, improve energy utilization rate.
Further, preferably, the delivery port position of described water tank 1 is provided with temperature sensor 7, described temperature sensor 7 is connected by central control module 8 with water pump 3 with described heater 2, utilize the delivery port position of the exclusive detection water tank 1 of temperature sensor 7, again water temperature numerical value is changed into signal and be sent to described central control module 8, when water temperature lower than set desired value time, central control module 8 starts water pump 3 and heater 2 automatically, circulation is drawn back temperature lowering water and is heated, after water temperature returns back to desired value, stop immediately, realize backwater, insulation automation.
The above, be better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, within all should falling into protection scope of the present invention.
