Abstract
The utility model relates to a heat pump water heater, and belongs to the technical field of water heaters. The heat pump water heater mainly comprises a circulatory heat exchange system consisting of a compressor, a condenser and an evaporator, and an inner water tank, wherein the condenser in the circulatory heat exchange system and the inner water tank form a heat exchange structure, an electric heating device is attached to the compressor, and particularly, a heating cable is wrapped on the lower portion of the compressor. Therefore, the heat pump water heater guarantees that the compressor is not a lowest temperature point of the whole heat pump system any more, refrigerant and oil are constantly separated from each other so that 'oil leakage on starting' can be avoided, and the compressor at low temperature can be quickly started to work, thereby shortening non-normal working time, greatly shortening water heating time of the water heater, and better meeting demands of users.
Description
Technical field
The utility model relates to a kind of Teat pump boiler, and especially a kind of family expenses wall hanging type heat pump water heater belongs to technical field of water heaters.
Background technology
Cycling hot exchange (the being heat pump) system that Teat pump boiler mainly is made of compressor, condenser, evaporimeter and have water inlet and the inner bag water tank of delivery port is formed.Condenser and inner bag water tank constitute heat exchange structure in the cycling hot exchange system.During work, the refrigerant in the cycling hot exchange system in the condenser link with heat transferred inner bag water tank, thereby wherein hot water of heating.Because Teat pump boiler has the advantage of energy-conserving and environment-protective, therefore obtain in recent years popularizing rapidly.
Yet; because the water temperature of using the back Teat pump boiler is all the time than environment temperature height; shut down in the compressor of back and have cold-producing medium; the big temperature difference between this water temperature and the circumstance of temperature difference causes cold-producing medium to have moving to compressor and oily trend of mixing; when in a single day the result started shooting in next time; the cold-producing medium evaporation is taken oil out of compressor, causes the compressor oil starvation, breaks down.
The utility model content
The purpose of this utility model is: the problem at above-mentioned prior art exists, and propose a kind of Teat pump boiler that can avoid the compressor oil starvation, thereby realize protection compressor, prolong its service life.
In order to reach above purpose, Teat pump boiler of the present utility model mainly is made up of cycling hot exchange system and inner bag water tank that compressor, condenser, evaporimeter constitute; Condenser in the described cycling hot exchange system and inner bag water tank constitute heat exchange structure; Its improvements are: be attached with electric heating device on the described compressor.Especially be wound with heating tape in the outside of compressor, promptly described electric heater is the heating tape that is wrapped in the compressor outside.
The utility model further improves: described heating tape is wrapped in below the compressor design pasta.
The utility model further improves: described compressor is piston compressor or rotor-type compressor.
Like this, can guarantee that compressor no longer is the minimum temperature point of whole heat pump, thereby make cold-producing medium and oil be separated from each other all the time, avoid " oil is run in start " phenomenon; And the compressor that is in keeping warm mode can enter duty rapidly after start, shortens the time of non-normal working, thereby has shortened the time of water heater heat hot water greatly, can satisfy user's user demand better.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the complete machine structure schematic diagram of an embodiment of the utility model.
Fig. 2 is the heat pump part-structure schematic diagram of Fig. 1 embodiment.
Fig. 3 is the structural representation of compressor among Fig. 2.
The specific embodiment
Embodiment one
The Teat pump boiler structure of present embodiment such as Fig. 1, Fig. 2 and shown in Figure 3 contain the cycling hot exchange system that is made of compressor 9, condenser 4, evaporimeter 6, and inner bag water tank 3.The condenser 4 of cycling hot exchange system is shape in the shape of a spiral, constitutes heat exchange structure with built-in mode and inner bag water tank 3.Inner bag water tank 3 and cover on filled with foaming material 2 between its outer shell 1.The compressor 9 of cycling hot exchange system, evaporimeter 4 etc. all cover in the heat pump case 8 that is connected with shell 1.
Need to prove, the less situation of indoor/outdoor temperature-difference is not opposite when not moving with general air conditioner, water temperature and circumstance of temperature difference when heat pump is out of service in the Teat pump boiler in the water tank are bigger, therefore cold-producing medium might be moved to compressor and oil mixing fully, when next heat pump is opened operation, cold-producing medium evaporation meeting is taken oil out of compressor, causes compressor oil starvation fault.For fear of this phenomenon, present embodiment has adopted the measure at compressor (piston type or rotator type) 9 bottoms (particular location is below the compressor design pasta) wrap round heat tracing band 5.Like this, when heat pump is out of service, can make compressor keep temperature required, avoid the remarkable temperature difference occurring between compressor bottom and the water tank, thereby keep cold-producing medium to separate mutually, effectively avoid start to run oil with oil phase by the electrical heating heating tape.Evidence, the Teat pump boiler of present embodiment also have having a few of remarkable shortening unsocial hours.Test shows, after the like product of no heating tape started, heat pump was because the temperature of compressor is lower, and therefore about 14 minutes is abnormal operating state, and promptly heat pump does not heat on the contrary in heat absorption.And shorten to the improper heat time heating time of present embodiment less than 4 minutes, thereby shortened time of heat hot water greatly, make the user experience be improved significantly, obtained the effect of killing two birds with one stone.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
