Abstract
The utility model relates to an energy-saving instant heating electric water heater which is composed of three parts. One part is arranged in a cavity of the instant heating electric water heater and comprises an instant electric water heater, a heat exchanger and a water pump; the other part comprises a water filtering floor drain and an insulating pad. Because the utility model adopts a waste water collection tank with a small volume, the waste water collection tank can be conveniently connected with a floor drain on the ground of a shower room or can be directly arranged in the floor drain. The installation is very convenient and moreover, the area of a shower room is not occupied. Simultaneously, a high-efficient heat exchanger which can carry out heat exchange with waste hot water is also connected under the water heater, sufficiently recovering and using the heat energy of the waste hot water, and the power of the electric water heater can be reduced.
Description
Technical field
The utility model belongs to a kind of hygiene equipment, particularly a kind of energy-saving instant electric water heater.
Electric heater has been applied to the bathing place of family and public arena widely owing to adopt the cleanest energy, also more and more is subjected to more people's welcome simultaneously.But present electric heater serves as at most with the water tank storage-type, and the drawback one of water storage electric heater is to need long-term energising to cause meaningless energy loss, the 2nd, can't promptly lead to instant heating, and influenced its convenience.Although some instant electric water heaters occurred, also solved the electric leakage safety problem that people are concerned about most, too big but its fatal defective is a power, as water yield 4 liters/minute instant electric water heater, its power reaches 8KW, and the sensation of still having a bath in the winter time water temperature is on the low side.These two kinds of electric heaters all do not have the recycling device of spent hot water.When having a bath, the water that washed generally also contains higher heat energy, for making full use of this partial heat energy, people have proposed some and have utilized the back-heating type electric shower-bath of waste heat, a kind of back-heating type energy-saving showering device is all disclosed as Chinese patent 99234907.9 and 00226012.3, it mainly is to be provided with the shower bath base that reclaims waste water below shower, and effluent storage is carried out heat exchange with cold water in this base.Its defective is to carry out heat exchange in base, and its volume is bigger, seems heavy, makes its installation and use occasion be restricted.
Summary of the invention
The utility model purpose is a kind of energy-saving instant electric water heater of design.
Specifically, a kind of energy-saving instant electric water heater, have electric heater and control circuit (1), on the water tank of electric heater, be connected to hot-water outlet pipe (2), also be connected with heat exchanger (4) on its electrothermal water heater's water tank and advance preheating and cross water pipe (3), advance preheating and cross water pipe (3) and link to each other, advance cold water pipe (8) and link to each other with the cold water water inlet tap of heat exchanger (4) with the cold water faucet of heat exchanger (4); Simultaneously mat insulation (13) is arranged and can be communicated with or be positioned over spent hot water's feeder (12) in the floor drain with shower cabinet ground floor drain in the water heater arranged beneath, spent hot water's feeder (12) is connected with pump water inlet (7) by the bend pipe (16) of bottom, pump water inlet (7) is connected with water pump (5), water pump (5) is connected the back and is connected with the hot water water inlet tap of heat exchanger (4) with pumping line (6), hot water effluent's mouth of heat exchanger (4) is connected with drainpipe (9).
On spent hot water's feeder (12) top and/or the bottom filter course (14) is installed.
The utility model can be connected with the floor drain on shower cabinet ground or directly be placed in the floor drain very easily owing to adopted the very little waste water collection tank of volume, not only installs very conveniently, and does not take the shower cabinet area; Simultaneously under water heater, also connected the high efficiency heat exchanger that can carry out heat exchange, fully recycled spent hot water's heat energy, can reduce the power of electric heater with the spent hot water.

The specific embodiment
Energy-saving instant electric water heater is made up of three parts, and a part is in instant electric water heater's cavity, comprises an instant electric water heater; Heat exchanger and water pump another part are drainage floor drain and mat insulation.As shown in drawings, a kind of energy-saving instant electric water heater, have electric heater and control circuit (1), on the water tank of electric heater, be connected to hot-water outlet pipe (2), it is characterized in that also being connected with on electrothermal water heater's water tank heat exchanger (4) and advance preheating and cross water pipe (3), advance preheating and cross water pipe (3) and link to each other, advance cold water pipe (8) and link to each other with the cold water water inlet tap of heat exchanger (4) with the cold water faucet of heat exchanger (4); Simultaneously mat insulation (13) is arranged and can be communicated with or be positioned over spent hot water's feeder (12) in the floor drain with shower cabinet ground floor drain in the water heater arranged beneath, spent hot water's feeder (12) is connected with pump water inlet (7) by the bend pipe (16) of bottom, pump water inlet (7) is connected with water pump (5), water pump (5) is connected the back and is connected with the hot water water inlet tap of heat exchanger (4) with pumping line (6), hot water effluent's mouth of heat exchanger (4) is connected with drainpipe (9).On spent hot water's feeder (12) top and/or the bottom filter course (14) is installed.
Its operation principle is as follows:
The flow of hot water of bathing is on mat insulation, flow into floor drain by mat insulation, floor drain is for having a water chamber and a sets filtering device under special the making, water flows in the water chamber by filtering the back, in water pump process water pipe suction heat exchanger, in interchanger, carry out heat exchange with running water, allow running water fully absorb the heat that water is crossed in bathing, then the water of bathing is discharged, the running water of preheating enters in the instant electric device after by heat exchanger and heats, and flows out by shower nozzle and carries out bathing, heat forms a circulation like this, reduced the loss of bathing process heat, after so circulating, can energy savings about 70%.
