Abstract

PURPOSE:To make an exhaust and ventilating equipments unnecessary, obtain hot water by making use of exhaust and its latent heat in a bath room and enable to make use of said bath room as a dry chamber at the unused time of the bath room, by making an evaporator and a fan in a heat pump equipment position within an air circulation path. CONSTITUTION:Air is circulated within a circulation path (c) and a bath room (a) by a fan 3, which is deprived of its heat through an evaporation action by an evaporator 2 of a heat pump, cooled and dehumidified. Refrigeration medium gas turning into a high temperature and high pressure by a compressor 1 is liquidized and radiated in a hot water tank forming a condenser 4 and takes out heated water from a discharge side of a circulation path 7 as hot water. The bath room is used as a dry chamber by circulating air in the bath room as dry air by providing a bypass duct 8 of a refrigeration medium connectable with a secondary side of the compressor and a secondary side duct of the condensor through reed valves 9, 10 and providing a heater 11 formed by making use of the refrigeration medium gas turning into the high pressure and the high temperature in a heat pump cycle on a reflux side in an exhaust circulation path.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention recovers and uses the latent heat of the air in the bathroom to obtain hot water, and also dries and circulates the air, making it possible to use the bathroom as a drying room. It relates to an air utilization device in a bathroom.

Because the bathroom is filled with steam due to evaporation from the hot water tank, ventilation windows are installed, an FC or duct is installed, and a fan is used to exhaust the steam inside the bathroom to the outside. This was extremely uneconomical, as the volume of the bath was 3 to 5 times the hourly bath volume, and the costs for equipment such as ducts and fans were considerable.

The present invention eliminates the need for ventilation equipment due to such exhaust volume, utilizes the exhaust air in the bathroom, uses its latent heat to obtain hot water, and makes it possible to use one room as a drying room when the bathroom is not in use. The first invention is to open an entrance/exit in a bathroom to form a ring path for circulating the air in the room, and to locate an evaporator and a fan in the heat pump equipment in the skeleton air circulation path. The water that communicates with the condenser inside (
It is characterized by extracting hot water from the discharge pipe of the shield ring road, and the second
The invention provides a refrigerant gas pipe that can be connected to the secondary side of the compressor and the secondary side of the condenser through an on-off valve in the heat pump equipment described above. By placing a heater on the reflux side of the air circulation path inside the bath, the air in the bathroom is cooled and dehumidified using a heat pump cycle, or the air heated by the heater is returned to the bathroom. It is characterized by C.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the first invention, in which a is a bathroom and b is a bathroom.
is installed in bathroom a; hot water tank; C is an air circulation path in bathroom a with an entrance to bathroom a; A is a compressor (1);
, a heat pump consisting of an evaporator (2), a fan (3), a condenser (4), and an expansion valve (5). Therefore, by the cycle of the heat pump, the refrigerant gas is heated to a compressor + 11 (the refrigerant gas becomes higher temperature and pressure is sent to a condenser + 4). The pressure is reduced, and then evaporation is carried out in the evaporator (2), leading to the compressor (11).

The air containing steam generated in the bathroom a is circulated through the circulation path C and the bath ma by a fan (3), and the heat in the air is removed by the evaporation action of the heat pump evaporator (21). The condensed water is cooled and dehumidified and returned to the bath Ma.P1 The condensed water is received by a dish (6) and drained.In the condensation stage of this heat pump cycle, 4 VC of hot water is supplied and discharged in the water circulation path (7). can be heated and taken out as hot water from the discharge side of the circulation path (7).

In this way, while the air in bathroom a is being circulated by the fan (31), its retained heat is recovered and cooled and dehumidified during the evaporation stage of the heat pump cycle, and the recovered latent heat heats the water in the hot water tank through the condensation action and is used for hot water supply. This hot water can be effectively used for washing the toilet or heating the room late at night.

FIG. 2 shows an embodiment of the second invention. In the heat pump cycle of the first invention, the compressor il+ is
Solenoid on-off valve +911 for the next side and the secondary side pipe of the condenser (4)
1 was provided, and the warmer (111) formed by the pipe (8) was located on the reflux side of the air circulation path C in the bathroom.

In the above configuration, when the bathroom a is not used as a bath and the heat pump is activated, the fan 13) is driven 1.
The air in the bathtub a circulates in the direction of the arrow through the circulation path C, and through the heat pump cycle, the heat is removed by the evaporator (21) and the air is dehumidified to become dry air. In this state, when the solenoid valve +91 is opened and the LIa valve II is closed, the refrigerant gas, which becomes high-pressure and high-temperature through the compressor 111, flows into the bathtub (8). The air inside the bathroom is circulated through the evaporator (2), cooled and dehumidified by the evaporator (2), then heated and dried by the heater (II) and blown into the bathroom a as super-warmed air, thus cooling the inside of the bathroom a. Alternatively, it can be used as a drying room.

In this way, according to the first invention, in order to exhaust the air containing steam in the bathroom, an exhaust circulation pipe communicating with the bathroom is provided without providing an exhaust equipment such as an exhaust duct, and this is combined with a heat pump. The latent heat of the exhaust gas can be recovered and used to obtain hot water, and the cooled and dehumidified dry air can be returned to the bathroom, and according to the second invention, the refrigerant gas that becomes high pressure and high temperature in the heat pump cycle. By forming a heater that utilizes air flow and installing it on the recirculation side of the exhaust circulation path, the air in the bathroom can be circulated as dry air into the bathroom, allowing the bathroom to be used as a drying room. It has the effect of
