Description

  The present invention relates to a bathroom ventilation air conditioner that performs ventilation air conditioning of a bathroom or the like using a heat pump.

  2. Description of the Related Art Conventionally, various types of arrangement structures of ventilation air conditioners and air conditioners such as bathrooms using heat pumps have been proposed.

  As a ventilation air conditioner such as a bathroom using a heat pump, a heat pump part including a compressor, a heat exchanger, etc. is integrally arranged in the main body, the main body is arranged on the ceiling surface of the bathroom, and an intake port and an exhaust port are provided. It is formed to face the bathroom, and the grille that covers the air intake and exhaust vents is attached to the ceiling surface of the bathroom, and the heat is dissipated (or absorbed) into the bathroom air in the heat exchanger provided in the main body. There is one that ventilates the bathroom with a ventilation fan installed in the main body. And since this kind of thing is a heat pump integrated type, it is not necessary to connect refrigerant | coolant piping at the time of construction, and the main body was the structure installed in a bathroom ceiling surface (for example, refer patent document 1).

  Also, the heat pump is separated into an outdoor unit and an indoor unit, and heat is absorbed (or radiated) from outside air in the heat exchanger provided in the outdoor unit, and heat is radiated (or absorbed) into the bathroom air in the heat exchanger provided in the indoor unit. By doing so, there are some which air-condition the bathroom and ventilate the bathroom without recovering heat by a ventilation fan provided in the indoor unit. And this kind of thing is the structure which isolate | separates and installs a heat pump in the inside of a bathroom, and the exterior, The construction which pipe-connects the inside of a bathroom and the exterior at the time of installation was required (for example, refer patent document 2).

In addition, the air-conditioning equipment installation structure under the floor maintains the intake and exhaust efficiency by installing the outdoor unit of the air-conditioning equipment facing the outside through the opening in the floor with an opening communicating with the outside on the outer wall. In some cases, the exterior quality of the house can be improved because the outdoor unit is not installed outdoors (see, for example, Patent Document 3).

(Embodiment 1)
FIG. 1 is a sketch of a living space in which a ventilation air conditioner according to an embodiment of the present invention is installed. In FIG. 1, an indoor living space 1 is partitioned into a living room 2, a bathroom 3, a dressing room 4, a toilet 5, and the like as an indoor space. 6 is installed. The main body 6 includes an exhaust duct 7 that communicates with the main body 6 and the outside, a first air intake duct 9 that communicates with the main body 6, and a first air outlet 10 that opens into the bathroom 3. The first circulation duct 11 that communicates with the body 6 and the second air inlet 13 that opens to the dressing room and the second air intake duct 13 that communicates with the body 6 and the second air outlet 14 that opens to the dressing room 4 and the body 6 The main body 6 communicates with the second circulation duct 15 that communicates with the third intake port 16 that opens to the toilet 5 and the third air intake duct 17 that communicates with the main body 6 and the third air outlet 18 that opens at the toilet 5. A third circulation duct 19 is connected.

  In addition, a circulation fan 20 is disposed inside the main body 6, the first intake duct 9 communicating the bathroom 3 and the main body 6 is on the suction side of the circulation fan 20, and the first circulation duct 11 is an outlet of the circulation fan 20. Connected to the side. Therefore, when the circulation fan 20 is operated, the air in the bathroom 3 is sucked into the circulation fan 20 from the first intake port 8 through the first intake duct 9 and is blown out from the first outlet 10 to the bathroom 3 through the first circulation duct 11. It will be.

  A ventilation fan 21 is disposed inside the main body 6, and an exhaust duct 7 that communicates the outdoor body with the main body 6 is connected to the blowing side of the ventilation fan 21, and a second intake air that communicates the dressing room 4 and the main body 6. The duct 13 and the third intake duct 17 that communicates the toilet 5 and the main body 6 are connected to the suction side of the ventilation fan 21. Therefore, when the ventilation fan 21 is operated, the air in the dressing room 4 and the toilet 5 is sucked into the ventilation fan 21 from the second air inlet 12 and the third air inlet 16 through the second air intake duct 13 and the third air intake duct 17 and exhausted. It is exhausted to the outside through the duct 7.

  And if the ventilation fan 21 is continuously operated, the inside of the indoor living space 1 becomes negative pressure, so that fresh outside air is supplied from the air supply opening 22 opened on the wall facing the outside of the living room 2 as the indoor space. The living space 1 will be ventilated. Since this ventilation operation needs to be performed continuously when the confidentiality of the building is high (24-hour ventilation), the ventilation fan 21 corresponds to a predetermined ventilation amount, for example, about half the volume of the living space 1 in one hour. Operate continuously to ensure ventilation.

  The living room 2 is provided with an air conditioner 23 for controlling the temperature of the room. The air conditioner 23 is air-conditioned in the summer and heated in the winter to keep the room temperature properly. Therefore, when continuous ventilation operation is performed throughout the year as described above, in the living room, cooling by the air conditioner 23 is performed in the summer, and heating by the air conditioner 23 is performed in the winter, so that a predetermined temperature range, for example, 20 ° C. to 30 ° C. The air controlled to 0 ° C. is sucked into the second air inlet 12 and the third air inlet 16 through the louver and undercut portions of the door 24 of the dressing room 4 and the door 25 of the toilet 5, and passes through the main body 6 of the ventilation air conditioner. It will be discharged outdoors.

Therefore, when the other-room fan 26 is operated, the air after being air-conditioned by the main body 6 is blown out from the second outlet 14 to the dressing room 4 through the second circulation duct 15. Further, the air after being air-conditioned in the main body 6 is blown out from the third outlet 18 to the toilet 5 through the third circulation duct 19.

  With the above configuration, even when there is no space for installing the main body 6 in the vicinity of the bathroom 3, the main body 6 can be installed in a place away from the bathroom 3, and by installing the main body 6 in a place away from the bathroom 3. The main body 6 can be operated without transmitting vibrations and noises to the bathroom 3, and there are less restrictions on the external dimensions and shape of the main body 6. Only the outlet 10 may be provided.

  Thus, according to the bathroom ventilation air conditioner of Embodiment 1 of the present invention, the main body 6 can be installed even when there is no space for installing the main body 6 in the vicinity of the bathroom 3, and the air conditioning of the bathroom 3 can be performed. In addition, by installing the main body 6 at a location away from the bathroom 3, it is possible to operate without transmitting vibration and noise of the main body 6 to the bathroom 3, and there are restrictions on the external dimensions and shape of the main body 6. By reducing the number, it becomes possible to improve the degree of freedom in designing the main body, and since only the first air inlet 8 and the first air outlet 10 need be provided in the bathroom 3, the design in the bathroom 3 is simplified. In addition, installation and maintenance are facilitated by installing it under the floor, and workability is improved.
