Abstract

PURPOSE:To shorten a drying time by raising emitted air to high temp. under heating by a heat pipe, in a dehumidifier using a heat pump, by mounting a heat pipe having a condensation part interposed between a heat exchanger for evaporation and a heat exchanger for condensation. CONSTITUTION:The condensation part 6a of a heat pipe 6 is interposed between the evaporator 1 and condenser 2 of the heat pump of a dehumidification dryer using a steam compression type heat pump utilizing a room such as a bathroom in the drying of clothings and the evaporation part 6b of said heat pipe 6 is arranged to a heat source 7 utilizing waste heat of hot water remaining in a bathtub or air outside a room or the open air. Heat pumped up from a heat source 7 in the evaporation part 6 is fed to the condensation part 6a to heat low temp. air passed through the evaporator 1 of the heat pump. Further, emitted air is raised to high temp. under heating by the condenser 2 to be sent out. By this method, indoor temp. is raised and a drying time is shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a dehumidifying dryer using a heat pump.

(Background technology) Conventionally, a dehumidifying dryer using a vapor compression heat pump as shown in Fig. 2 has been used to dry clothes indoors such as a bathroom. 2 is an AI condenser, 3 is a compressor, and 4 is an expansion valve.The evaporator 1 and the condenser 2 are placed behind the fan 5, and the air passes through the evaporator 1 and the # detector 2 in this order. As a result, moisture in the air is removed by the evaporator 1, and the air is heated by the amount of energy input to the compressor 3 by the condenser 2 and returned to the room, and this cycle is repeated. This promoted the movement of moisture from the material to be dried to the air.

Although such a dehumidifying drying method using a heat pump has the advantage of higher drying efficiency than a heating method using a heater or the like, it has the disadvantage that the drying time is somewhat long.

[Purpose of the invention]

An object of the present invention is to provide a dehumidifying dryer using a vapor compression heat hop, which shortens the drying time while maintaining a high dryness I; JJ4S.

(Disclosure of the Invention) The dehumidifying dryer of the present invention includes a compressor, a condensing heat exchanger, an expansion valve, and an evaporating heat exchanger connected in series, so that air flows through the evaporating heat exchanger and the condensing heat exchanger. a heat pump having a condensing section and an evaporating section provided at both ends thereof, the condensing section being interposed between the evaporating heat exchanger and the condensing heat exchanger, and this heat pipe. and a heat source that supplies heat to the evaporation section.

In other words, in this invention, the air that has passed through the evaporation heat exchanger and has become extremely low in temperature is heated by the heat pipe, and then further heated by the condensation heat exchanger to raise the discharge air to a high temperature. This makes it possible to increase the drying time and shorten the drying time.

An embodiment of the present invention will be described based on FIG. Note that the same constituent members as shown in FIG. 1 are designated by the same reference numerals and their explanations will be omitted. In FIG. 1, reference numeral 6 denotes a heat pipe, and this heat pipe has a condensing section 6a and an evaporating section 6b formed at both ends thereof, and collects heat in the evaporating section 6b and dissipates the heat in the condensing section 6a.

The condensing section 6a is interposed between the evaporator l and the condenser 2 of the heat pump. Further, the evaporation section 6b is arranged at the heat source 7. As the heat source 7, for example, exhaust heat such as residual hot water in a bathtub or air outside the room or the like can be used.

Therefore, the heat pumped up from the heat source 7 in the evaporator 6b is transferred to the condensing part 6a, where it heats the low-temperature air that has passed through the percussion device l of the heat pump, and further heats it in the condenser 2 to discharge the discharged air. can be sent out at a higher temperature.

Therefore, it can be suitably used as a bathtub dryer, for example.

Here, the function of the heat piper is to pump up waste heat and the like from the evaporating section 6b and releasing it to the condensing section 6a, so basically the evaporating section 6b must be located at a lower position than the condensing section 6a.

〔Effect of the invention〕

According to this invention, heat can be pumped from outdoor air or waste fluid without using special complicated equipment, making it possible to maintain high drying efficiency while shortening drying time due to increased indoor temperature. It has the effect of becoming.
