Key.
Such as Chinese patent literature CN2746313Y discloses a kind of heat pump water heater with horizontal water tank, wherein by horizontal
Two pieces of dividing plates with the axis perpendicular of water tank are provided with water tank, passage, dividing plate both sides are provided between dividing plate and water tank
Water tank space communicated by the passage, thus the cold water in water tank flows out Jing after fully heating, and the mixed water yield for making hot and cold water subtracts
Few, hot water amount increases, delivery port to go out water-cooled uniform.
In above-mentioned patent document, whether following in static type Teat pump boiler or embodiment 2 in its embodiment 1
Ring type Teat pump boiler, because the axis perpendicular of its horizontal water tank median septum and water tank is arranged, therefore, the single sky between dividing plate
Interior water is still divided into the cold water of bottom, the mixed layer between the hot water and cold water and hot water of top layer, therefore, in client's water
When, when entering inner water tank near the cold water of water inlet pipe, when hydraulic pressure is excessive, can still cause the water in the water tank space can be in water
(leftward space i.e. in its accompanying drawing 1) is stirred in the presence of pressure, water tank water temperature is quickly reduced, adjacent with water inlet pipe so as to affect
The hot water in the space of dividing plate both sides, client's rate of thermal water utilization is still not high enough.
The content of the invention
Therefore, the technical problem to be solved in the present invention is to overcome water heater of the prior art due to the mixed water rate of hot and cold water
Height, the low fast defect of Water in Water Tank temperature drop mixes the water-heater water tank of water rate and with the water so as to provide a kind of reduction water tank hot and cold water
The water heater of case.

Loop back path is connected with water tank, and wherein main frame 7 is air source heat pump.Referring to the bottom portion of accompanying drawing 2, closed circuit and water-heater water tank
Connection, main frame 7 constitutes closed circuit by water circulating pump with the bottom portion of water-heater water tank.Thus, main frame 7 is only to water tank bottom
The water in portion is circulated heating, and when unit starting, it carries bottom portion water system circulation of the circulating pump to second partition below 5
Heating, and relatively small is affected on the water system of second partition more than 5, thus while heating is started, do not affect upper layer part
Hot water effluent lead.Further, needs are arranged according to water tank, the embodiment two is that the water-heater water tank in accompanying drawing 2 also can be replaced
It is changed to the water tank of horizontally set as shown in Figure 4.
The water heater of the present invention passes through water of the heater block to water tank bottom portion as a result of stratified water tanks structure, mainly
Heating, can effectively reduce the mixed water of water tank, lift client's rate of thermal water utilization；Reduce heat pump frequent starting number of times；Improve hot water to go out
Water speed.
Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
