Description

[Detailed Description of the Invention] Industrial Field of Application The present invention recovers exhaust heat during heating drying to produce hot water, and at the same time recovers 7 (W) gas in the exhaust gas at the same time. Heat supply device i'i (J dryer) that does not require an external exhaust device 1. Structure of conventional example and its problems Conventionally, this type of dryer 1, as shown in Fig. 1, exhausts indoor air. The air is sucked in by the blower 2, heated by the heater 3, and guided to the rotary drum 4 in the dryer 1 to dry the laundry 6.
Remove moisture by heating. While the heat is removed by the laundry 5, the air that has been given moisture becomes humid air and flows into the duct 1.
-6 was discharged outdoors. In the figure, 7 is the blower 2, the motor that is the drive source for the drum 4, 8 is the air intake provided at the front of the drum;
It has 110.

However, in this configuration, exhausting humid air outdoors is a necessary condition for increasing the drying effect.

That is, if the moist air is not discharged outdoors, the moist air may be sucked in again, reducing drying efficiency, or condensing indoors, which is undesirable.

Furthermore, from the point of view of energy saving, the energy 1β is high.
Since the publication was carried out outdoors in full contact with heated humid air, there were two issues: exhaust air, which had to be used effectively, and effective use of the heat accompanying the exhaust air.

Purpose of the Invention The present invention solves these conventional problems and provides a multi-functional dryer that does not require exhaust to the outside and can simultaneously produce hot water by effectively recovering waste heat. ! , the purpose is to provide S.

Structure of the Invention In order to achieve the above object, -h 'J'l'I r
1: A refrigerant evaporator is installed in the exhaust path of a conventional dryer, and a hot water storage tank is installed in which exhaust heat is removed as vaporization heat and water is heated using a heat pump method to produce hot water.

With this configuration, dehumidification and exhaust heat recovery can be performed efficiently.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2, 3, 4, and 5.
This will be explained using figures.

In FIG. 2, four drums for storing the laundry 5 are installed in the upper part of the dryer 1, and are slowly rotated by a motor 7 in order to dry the laundry 5 efficiently and uniformly.

The air heated by the six heaters 3 is sucked in through the front opening 8 of the drum 4 by the blower 2, heats and removes moisture from the laundry 5, and then passes through the exhaust port 110 provided on the bottom plate 9 of the drum 4.
More leakage. During the outflow process of outside = lK-, the blower 2
Transporter evaporation stagnation 1 consisting of a large number of fins installed at the rear of the
1, where it absorbs heat and removes moisture, flows through the dryer 1 as shown by the arrow, and is then heated by the heater 3)
, nI, 3 refrigerant evaporation packs 11, compressor 12, 'l'Af, which circulate in a closed circuit heated and guided into the drum 4.
lla R313 is connected to the expansion center 14 to form a closed circuit, and the medium reduced in pressure in the expansion center 14 is sent to the evaporator 11, where the exhaust heat from the dryer 1 is taken away as heat of vaporization. At the same time, water) is removed by converting it into water droplets on the fin surface.The medium that has been vaporized and heated in the evaporator 11 reaches the compressor 12 as shown by the arrow, where it is compressed and released as a high-temperature, high-pressure medium into the tank 16. The water is sent to the evaporator 13, where it radiates heat to heat the water in the tank, reaches the ++y heather valve 14 as a low-temperature and high-pressure medium, and is pressurized here and enters the river evaporator 11. Repeat.

In this manner, a large amount of moisture (4J) lands on the fins of the evaporator 11 due to heat absorption (absorption of vaporization force) from the humid air of the dryer 1, and is turned into water droplets and is not discharged from the train U116.

The air that has passed through the evaporator 11 comes into contact with the heater at the evaporator (fm) and is reheated, thereby further increasing the drying effect c1.

The operation of the dryer 1 is as shown in Figure 4.
The compressor 12 also starts operating at the same time.

However, if the hot water in the tank 15 is completely boiled, the heat recovery ability of the evaporated Hg 11 will be significantly reduced.

As an eleventh measure to prevent this, there is a hot water temperature 1'i installed outside the tank.
) A solenoid valve 20 branched into the hot water supply pipe 19 is automatically opened by the hot water supply pipe 18 to discharge hot water that has undergone transformation at a predetermined temperature and has a dehumidifying effect. I can do it.

The switch 21 is shown in Figs. 4 and 5 as shown in Fig. 3.
Stage L horn replacement - Tonadehiro Figure 5 A, I\'l position -: Only the blower 21 is closed, blower 21 is closed, blower 1 is in the l position, blower 1 is in the l position, blower 1 is in the l position.

In addition, all locations marked "C" are energized and dry.

Dehumidifies and boils water at the same time.

Effect of the invention As described above, according to the present invention, the following effects can be obtained.

(1) By arranging the refrigerant evaporator X,= in the air flow path within the dryer, dehumidification can be achieved and exhaust to the outdoors is not required.

(2) Hot water can be heated using heated humid air.
