Abstract

The utility model relates to a refrigerator with two purposes of refrigeration and heating. An additional evaporation board, a change valve and a filter are added besides the refrigerating system of an original refrigerator. An original compressor and a condenser are utilized to form the circulating system of a heat pump. A water pump is utilized to circularly heat water in two water tanks, and 30-40 L hot water with the temperature of 50-60 DEG C can be provided every day. Since a circulating pipe is arranged in the casing of the compressor, the working environment of the compressor can be improved. The utility model has the advantages of long service life and energy saving.

Description

Refrigerator with two purpose of refrigeration and heating

The utility model belongs to a kind of dual-purpose refrigerator for heating and refrigerating, and specifically this refrigerator possesses the refrigerating function except the same with general refrigerator, also possesses the heat of recovery and heat-production functions.

As everyone knows, existing refrigerator only possesses the refrigeration simple function, it utilizes cold-producing medium under the driving of compressor---the lower boiling characteristic of Fu Liang, constantly carry out the physics circulation, in refrigerator (freezing, the refrigerating chamber) space of limited capacity, absorb heat, promptly become steam state by heat absorption, and then in the refrigerator surrounding environment, promptly become liquid state by heat release from gaseous state inhaling the heat leakage that comes from liquid state, so just the heat leakage that cements out in the process of refrigerastion in surrounding environment, waste.

The purpose of this utility model is to have designed a kind of dual-purpose refrigerator for heating and refrigerating, it is except possessing refrigerating function, with coldly coming outside the freezing preservation food of making, can and utilize heat pump techniques to produce heat with the heat recovery and utilization that cements out in the process of refrigerastion simultaneously, to the water heating, use for life.Improved the working environment of compressor simultaneously, increased the service life and save electricity consumption.

For realizing goal of the invention, the utility model carries out following improvement to former refrigerator:

1, in the compressor housing of former refrigerator, is equiped with circulating water pipe, the thermal power transfer of compressor electrical power and the caloic of housing Nei Gaowenfu Leon gas are exchanged by the heat transferring medium water in the circulating water pipe, deliver to above the refrigerator by water pipe and water pump and in the water tank water in the case is heated;

2, the employing heat pump techniques utilizes compressor, the condenser in the refrigerator, set up evaporation plate, reversal valve, filter, water tank water pipe and water pump constitute heat pump circulating system, except the heat that recovery refrigerator process of refrigerastion cements out, also force to heat, to water storage heating in the water tank, provide life hot water;

3, scatter and disappear for reducing heat, heat-insulation layer is set in the water tank outside and water pipe surface.

The utility model and current refrigerator relatively have following advantage:

1, except having refrigerating function, also have heat-production functions to the heating of the water in the water tank, can provide every day 50-60 ℃ of left and right sides hot water 30-40 to rise life and use;

2, owing in compressor housing, install circulating water pipe, improve the compressor operating environment, improve the refrigerator refrigerating capacity;

3, reduce compressor power consumption, economize on electricity, and prolong compressor service life.
