Description

Cool-warm two purpose conditioning bed

The utility model relates to a kind of air conditioner for both cooling and heating bed that utilizes a miniature heat pump type air conditioner to adjust the bed surface temperature.

In the hot season, extremely to affix one's name to unbearablely, winter, temperature are low excessively, and the sleep that influences the people is had a rest.Dual-purpose air conditioner for changing in temperature is the ideal equipment of indoor temperature control, but because of the cost height, thermoregulator spatial dimension is big, and power consumption is big, installs and uses the expense height, and has limited its application.Heat pump type air conditioner is when system is warm, and outdoor temperature is lower than 5 ℃, and the condensation water on the evaporator fin will freeze and is frost, ventilate and be obstructed, air-conditioner is with regard to cisco unity malfunction, and in season of cold, outside air temperature is restricted the heating function of heat pump type air conditioner often in subzero.Though the electroheating type air-conditioner is not subjected to the influence of environment temperature, the thermal efficiency is very low.Applied for the air-conditioning bed (application number 922175012) of utility model patent,, its function of use and scope have been restricted because of solving refrigeration.Electric blanket can solve winter heating, and can not solve the refrigeration in summer.

The purpose of this utility model provides a kind of miniature heat pump type air conditioner that utilizes, and adjusts the temperature of bed surface, is adapted to the popular air conditioner for both cooling and heating bed that generally uses.

The purpose of this utility model is achieved in that in the mattress of a special hollow, with the bottom thermal insulation layer is arranged all around, bed surface can be ventilated, the evaporimeter of tailstock inside (condenser) connects with refrigeration system, when bed surface need be lowered the temperature, by artificial manipulation solenoid directional control valve, make compressor in mattress, supply low pressure refrigerant liquid, cold-producing medium evaporates in evaporimeter, and fan blows to cold air in the mattress, thereby reaches the purpose that reduces the bed surface temperature; When bed surface need heat up, by artificial manipulation, change the direction of solenoid directional control valve, the high-pressure refrigerant inverted running, at this moment, evaporimeter becomes condenser, makes in the mattress to heat up.In order to make bed surface that a suitable temperature be arranged, in mattress, be provided with a temperature controller, control walking, stopping of compressor by relay, reach the purpose of regulating the bed surface temperature.

Second kind of embodiment of the present utility model is direct-cooled (heat) formula, and evaporimeter (condenser) is distributed in the mattress, connects refrigeration system by pipeline, and heat exchange is directly carried out in mattress, thereby reaches the purpose that keeps bed surface that a suitable temperature is arranged.

The above-mentioned two kinds of embodiment of the utility model be between cold (heat) formula and direct-cooled (heat) formula, all can make split type:

Among cold between first kind (heat) formula embodiment, evaporimeter (condenser), fan, temperature controller.Circuit control and operation part are installed in the mattress, form a whole; Miniature heat pump type air conditioner, electromagnetism guide valve and power unit form a whole, and the two links up with two pipelines, and its operation principle is identical with first kind of embodiment.

In second kind of direct-cooled (heat) embodiment, evaporimeter (condenser), temperature controller, circuit control and operation part are installed in the mattress, form a whole; Miniature heat pump type air conditioner, solenoid directional control valve and power unit form a whole, and the two links up with two pipelines, and its operation principle is identical with second kind of embodiment.

The bed surface of air conditioner for both cooling and heating bed adopts nylon chemical fibre hoop structure, there is a metal framework top of mattress, be evenly equipped with many little hooks around the inner edge of metal framework, the nylon chemical fiber rope is single forms an annular, become bifilar two ends to be hooked on the little hook of opposite side, form a tightening force, be made into the groined type network structure in length and breadth.

According to the above, the air conditioner for both cooling and heating bed solved the hot season and dead season bed the adjustment problem, pump type heat dual-purpose air conditioner for changing in temperature relatively, the cost of air conditioner for both cooling and heating bed is low.Since only temperature adjustment among a small circle, the power of compressor little (150W is following), furthermore having adopted thermal insulation layer, hot and cold amount is lost seldom, so power consumption is seldom, and use cost is extremely low.Simultaneously, its heat exchange can be carried out indoor, and the work of refrigeration system is not subjected to the low excessively influence of outside air temperature, has enlarged its scope of application.Competitive list refrigeration air-conditioner bed, air conditioner for both cooling and heating bed had both solved the cooling of hot season bed, had solved the intensification of bed dead season again, had enlarged the function and the scope of application of air-conditioning bed; Owing to only use at night and noon, made full use of the low ebb electricity, not only do not conflict, and improved the utilization rate of electric power with power supply shortage; Compare electric blanket, the air conditioner for both cooling and heating bed had both solved winter heating, had solved the refrigeration in summer again; Safe in utilization, the health of air conditioner for both cooling and heating bed, harmless, its simple installation, good work environment, working service is convenient, does not need independent wiring, even generally use, also can not impact existing electrical network.

The air conditioner for both cooling and heating bed in theory with technical all be ripe, many parts can adopt general part, under the prior art condition, quality is guaranteed fully, is easy to organize large-scale industrial production.

In conjunction with the accompanying drawings utility model again is further described again below:
