Description

[Detailed description of the invention] This invention relates to the improvement of a dehumidifier using a refrigeration cycle, and aims to expand the functions of the dehumidifier by adding a function to convert cold water such as tap water into low-temperature water as necessary. One of its objectives is to

Dehumidifiers that utilize the condensation heat and evaporation heat of the refrigeration cycle have been widely known and sold.

However, since this dehumidifier is intended for indoor dehumidification, even if clothes are hung inside the room where the dehumidifier is being used, for example to dry clothes, the air used to dry the clothes will not be supplied. Since the temperature was almost the same as the room temperature, the drying efficiency was extremely poor.

Furthermore, as shown in Figure 2, this dehumidifier consists of a refrigeration cycle consisting of a compressor A, a thorough opening, a capillary tube H, an evaporator II, a three-way valve H, etc., and has only a dehumidifying function. .

The refrigerant flows in the direction of the solid arrow in the figure, and the two-way valve H is opened during defrosting to remove the frost adhering to the evaporator II.

Therefore, the present invention makes use of the advantages of the conventional dehumidifier described above, and allows the dehumidifier to be used as a dryer as needed.
Furthermore, the aim is to provide a multi-functional device that has the ability to obtain low-temperature water.Specifically, it can be installed in bathrooms, laundry rooms, etc. to preheat bath water, and convert cold tap water in winter into low-temperature water for use in laundry. The present invention provides a device that allows a small room in a bathroom or laundry room to be used as a drying room.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

In the figure, 1 is an electric compressor, and the discharge side is provided with a three-way valve 2 for switching the flow direction of refrigerant and a two-way valve 3 that is opened during defrosting.

A condenser 4 has one end connected to the three-way valve 2, and the other end connected to the first capillary tube A.

5 is an evaporator connected to the first capillary reach tube A, and in the middle of the connection, one end is connected to the three-way valve 2, and a 92nd capillary reach tube B is connected to the double pipe type heat exchanger. The other end of the series circuit consisting of the device 6 is connected.

The other end of the two-way valve 3 is connected to the refrigerant inlet side of the evaporator 5.

Water inlet end 7 or outlet end 8 of the double tube heat exchanger 6
is provided with an orifice 9 for activating the differential pressure switch 10.

Reference numeral 11 denotes a fan motor that drives an impeller 12 to circulate indoor air in the direction of arrow C.

Joints are provided at the water inlet and outlet ends 7 and 8 of the double pipe heat exchanger 6 so that rubber hoses and the like can be easily attached and detached.

The parts surrounded by the dashed lines in Figure 1 are integrated as a dehumidifier, and the outer box is designed to be portable or to be installed on the wall or corner of a bathroom or changing room, depending on its purpose. formed accordingly.

When performing dehumidification and drying in the above configuration, the three-way valve 2 is switched by a three-way valve changeover switch (not shown) or the like so that the refrigerant flows as shown by the dotted arrow in FIG.

Therefore, the refrigerant discharged from the electric compressor 1 is transferred to the three-way valve 2.
→ Condenser 4 → First capillary reach tube A - Evaporator 5 -
It flows in the order of electric compressor 1.

At this time, the two-way valve 3 is opened and closed by a timer or the like (not shown), and the frost adhering to the evaporator 5 is melted by the heat of the bypassed hot gas.

When the two-way valve 3 is opened, the refrigerant discharged from the electric compressor 1 has a large flow resistance in the first capillary reach tube A, so the two-way valve 3 → the evaporator 5 → the electric compressor 1. It flows in this order.

During the dehumidification/drying operation, the indoor air passes through the evaporator 5 by the impeller 12 driven by the electric motor 11, at which time the moisture in the air is dehumidified, and then passes through the condenser 4, at which time the air is reheated. .

Here, as is well known, when a dehumidifier's refrigeration cycle is operated in the same room, the input heat is radiated, so if the dehumidifier is operated in a small room such as a bathroom or changing room with a small heat capacity, the room temperature will rise due to the heat radiated. .

Under these conditions, the dryer function can be greatly improved.

Next, when heating water from a tap or the like to obtain low-temperature water, switch the three-way valve 2 so that the refrigerant flows as shown by the solid arrow in Figure 1 using a three-way valve selector switch (shown in the figure). do.

Therefore, the refrigerant discharged from the electric compressor 1 is transferred to the three-way valve 2.
→Double tube heat exchanger 6-2nd capillary tube B+
It flows in the order of condenser 5 → electric compressor 1.

At this time, a rubber hose 13 connected to a water faucet 15 and a rubber hose 14 extending to a bathtub or a washing machine tub are connected to the water inlet/outlet ends 7 and 8 of the double pipe heat exchanger 6. When the water faucet 15 is opened, the water flows to the double pipe heat exchanger 6.

As a result, the orifice 9 provided in the double tube heat exchanger
A main switch (not shown) can be operated by detecting the differential pressure before and after using the differential pressure switch 10.

The differential pressure switch 10 and the three-way valve 2 are linked to control the three-way valve 2 so that when the water faucet 15 is opened, the refrigerant flows in the direction of the solid arrow, and at the same time the main switch (not shown) is operated. You may let them.

The refrigerant discharged from the electric compressor 1 exchanges heat with water in the double pipe heat exchanger 6, thereby heating the water.

At the same time, the air from the impeller 12 absorbs heat from the indoor air in the condenser 5.

Further, during defrosting, the same operation as during dehumidification may be performed.

Therefore, when the double-pipe heat exchanger 6 is used, the cold water can be turned into low-temperature water, so it can be designed to obtain preheated water for washing or bath water.

Furthermore, by installing the device only in a small room such as a bathroom or a changing room, the room temperature can be raised by heat radiation from the device, so it can also be used as an efficient dryer.

Furthermore, since the dehumidifier with a water heater is integrated, it can be moved and used to dehumidify a room without using the double-pipe heat exchanger 6, resulting in energy saving and multi-purpose use. It can be used for any purpose.

As is clear from the above examples, the dehumidifier with a water heater of the present invention can easily dehumidify the room because it can dehumidify the room without using a double pipe heat exchanger. By using a heat exchanger, you can turn cold water into low-temperature water and use it as water for washing or preheating bath water.In addition, by installing it in a small room such as a bathroom or changing room, you can use the heat dissipation of the device to It has various advantages, such as raising the room temperature, turning the room into an efficient dryer, saving energy, and being able to be used for a variety of purposes.
