[0002]

2. Description of the Related Art Generally, in an air conditioner, in order to suppress indoor drying, water is supplied dropwise to a vaporizing humidifier provided adjacent to a heat exchanger, and the water is naturally evaporated. It is known that the evaporated moisture is blown into the room together with the conditioned air so as to humidify the room. In this evaporative humidifier, humidifying water is stored, and a humidifying filter that humidifies the air by evaporating the stored humidifying water naturally is disposed, and when the amount of humidifying water supplied to the humidifying filter exceeds the limit amount. Excess humidification water is discharged from the air conditioner to the outside via a drain receiver provided in the vaporizing humidifier.

In order to maintain proper humidification water injection into the humidification filter, a direct-acting water injection valve is provided in the humidification water supply pipe.

In a conventional direct-acting water injection valve, as shown in FIG. 6A, when an ON signal is input, the valve element is fully opened instantaneously,
When an OFF signal is input, energization control (ON-OFF control) is performed so that the valve element is completely closed instantaneously.

[0005]

In this type of direct-acting water injection valve, as shown in FIG. 6B, an overshoot at the time of valve opening causes an excessive amount of water to be discharged from the humidification water normally discharged at the time of valve opening. Because it is instantaneously discharged from the dynamic on-off valve,
There is a problem that excessive water is injected into the humidifying filter by that much, and this excessive humidifying water is scattered outside the vaporizing humidifier.

When the valve is closed, the supply of the humidifying water is stopped instantaneously, so that the water in the humidifying filter rapidly decreases and the humidifying filter dries, and is supplied indoors as shown in FIG. 6C. There is a problem that the amount of humidification decreases extremely.

An object of the present invention is to provide an air conditioner which solves the above-mentioned problems of the prior art, suppresses excessive supply of humidifying water, saves water, and can secure a substantially uniform humidifying amount. To provide.

The case 46 has a dome-shaped head 46A.
Is formed, and a sprinkler tube 46B is provided in the dome-shaped head 46A.
Are arranged. A humidifying water pipe 53 is connected to the sprinkling pipe 46B.
A humidification water supply pipe 40 (FIG. 1) for guiding a part of the supply water supplied to the humidification supply pipe is connected to the humidification water supply pipe 40, and a thermal valve 44 is connected thereto. The humidification water supply pipe 40 is in contact with at least one of a hot water outflow pipe 29 for sending hot water from the heat source unit 27 to the hot water heat exchanger 24 and a hot water return pipe 30 for returning hot water from the hot water heat exchanger 24 to the heat source unit 27. It is desirable to be arranged.

The humidifying water pipe 53 is incorporated in the indoor hot water heat exchanger 24 and arranged as shown in FIGS. The indoor hot water heat exchanger 24 is a fin-and-tube heat exchanger, in which heat transfer tubes (tubes) 24A and 24B are inserted through fin groups stacked one on another. , A lower multi-stage path, and a path between the paths is welded or brazed with a U vent pipe to form a series of flow paths.

Clean water (water supply) before being supplied to

The heat of the hot water flowing through the hot water heating tube 24A is transferred to the humidifying tube 24 via the fins.
B, the humidifying tube 24B and the humidifying water pipe 5
Since the water or hot water flowing through the humidification water pipe 53 is warmed and supplied to the evaporative humidifier 45, the humidifier 45 is heated.

The humidifying tube 24B itself may be connected to the sprinkling tube 46B as a humidifying tube without inserting the humidifying tube 53 into the humidifying tube 24B.

The hot water from the sprinkler tube 46B collides with the inner wall of the dome-shaped head 46A, flows out along the dome shape, and is dropped on the humidifying filter 47 which is arranged at an inclination. Thereby, reliable dropping to the humidifying filter 47 is ensured. The hot water dropped here humidifies the warm air passing through the heat exchangers 23 and 24, and the residual water is received by the residual water receiving portion 46C. This residual water receiving part 46C
Is collected in the back drain receiver 43 of the third heat exchange unit 23C through the residual water passage 46D.
The residual water channel 46D is formed at both ends of the case 46 so as not to protrude into the air channel, as is clear from FIG.

The humidifying filter 47 is housed in a holder 48, and a handle 48A is formed in the holder 48. Then, when the front exterior body 36 is opened as shown in FIG. 3, the humidifying filter 47 faces the front surface of the exterior body together with the element holder 48 so as to be able to be taken out.

The humidifying filter 47 is made of a material that easily contains moisture, such as a sponge. When the air passes through the humidifying filter 47, the water in the humidifying filter 47 is naturally evaporated, and the air blown out from the air outlet 38 into the room is humidified. This humidification is mainly performed during the heating operation of the air conditioner 10.

In this embodiment, a humidification water supply pipe 40 for supplying water to a humidification filter 47 is provided with a thermal opening / closing valve 44 for adjusting the flow rate of water flowing in the humidification water supply pipe 40 as shown in FIG.
Are arranged.

This thermal opening / closing valve 44 repeatedly opens and closes according to a fixed time set in advance.
As shown in the figure, when the open signal is received in the fully closed state, the state gradually reaches the fully open state after a predetermined time T3 (about 3 to 5 minutes), and the holding time T4 of this fully open state (about 3 to 5 minutes) is reduced. When a close signal is received in the fully open state, a predetermined time T5 (about 3 to 5
Minutes) to gradually reach the fully closed state. For example, when the thermal opening / closing valve 44 is provided with a coil, and the coil is energized, the valve body is gradually opened until the coil heat reaches the first temperature, and then the valve body is fully opened, and when the coil is demagnetized, The valve body is gradually closed until the coil heat is reduced to a second temperature lower than the first temperature, and thereafter, the valve body is constituted by a thermal valve which is fully closed.

As shown in FIG. 5A, the thermal opening / closing valve 44 is ON / OFF controlled. That is, the valve opening operation is performed over the valve opening command maintaining time T1 (about 10 to 15 minutes), and the valve closing operation is performed over the valve closing command maintaining time T2 (about 10 to 15 minutes).
), And the valve opening and the valve closing are alternately switched and controlled.

When an ON signal is input to the thermal opening / closing valve 44, the coil of the thermal opening / closing valve 44 is energized, and the valve body of the thermal opening / closing valve 44 is gradually opened after a valve opening time T3 and fully opened. To the state. During this time T3, the amount of humidified water injected from the thermal opening / closing valve 44 gradually increases as the valve body opens, as shown in FIG. 5B. After the valve body is fully opened, the valve body is held in the fully open state for a predetermined time (full open holding time T4). During this time, the humidification filter 47 is supplied with the humidification water flow rate normally discharged when the valve body is fully opened from the thermal opening / closing valve 44. Then, after the thermal opening / closing valve 44 is maintained in the fully open state, an off signal is input and the coil of the thermal opening / closing valve 44 is demagnetized.

The humidifying water is supplied to the humidifying filter 47 while the valve is opened in response to the ON signal in the fully opened state and the fully opened state is maintained, as shown in FIG. 5C. As described above, the amount of humidification supplied to the room increases.

The amount of humidification supplied while the thermal opening / closing valve 44 maintains the fully open state can be adjusted by increasing or decreasing the fully open holding time T4, and the maximum amount of humidification is adjusted. Here, the full-open holding time T4 is the energization time to the coil of the thermal opening / closing valve 44 (the valve opening command holding time
It is adjusted by increasing or decreasing 1).

Next, when the coil of the thermal opening / closing valve 44 is demagnetized, the valve body of the thermal opening / closing valve 44 is gradually closed after a valve closing time T5, and reaches a fully closed state. When the valve is closed, the amount of humidified water injected from the thermal opening / closing valve 44 gradually decreases as the valve body closes, as shown in FIG. 5B. After the valve body is fully closed, the valve body is held in a fully closed state for a predetermined time (full-close holding time T6). Then, when the thermal opening / closing valve 44 receives the ON signal again, the valve body of the thermal opening / closing valve 44 is opened for the valve opening time T3, and the humidifying water is supplied.

When the heat-operated on-off valve 44 is fully opened and receives an off signal and the valve body of the heat-operated on-off valve 44 is closed, the amount of humidification water supplied to the humidification filter 47 gradually decreases. After that, the humidification amount supplied to the room does not suddenly decrease, and the humidification amount gradually decreases as shown in FIG. 5C. While the humidifying water is not supplied to the humidifying filter 47 while the thermal opening / closing valve 44 holds the fully closed state, the humidification amount is reduced until the thermal opening / closing valve 44 receives an ON signal.

The amount of humidification supplied while the thermal opening / closing valve 44 maintains the fully closed state can be adjusted by increasing or decreasing the fully closed holding time T6, and the minimum amount of humidification is adjusted. . For example, when the fully closed holding time T6 is shortened,
The reduction of the humidification water in the humidification filter 47 is correspondingly reduced, and accordingly, the reduction of the humidification amount supplied to the room is suppressed.

Here, the fully closed holding time T6 is the demagnetizing time of the coil of the thermal valve 44 (the valve closing command maintaining time T6).
It is adjusted by increasing or decreasing 2).

The thermal valve 44 is controlled when a humidifying operation is selected and commanded by a controller (not shown), a remote controller (not shown), or the like. When the humidification operation is selected, the above-mentioned thermal opening / closing valve 44 performs the above-mentioned opening / closing operation by ON-OFF control as shown in FIG.
As the valve opens and closes, the amount of humidified water injected changes to a trapezoidal shape as shown in FIG. 5b. Accordingly, the amount of humidification supplied to the room changes smoothly as shown by the solid line in FIG. 5C, and the difference between the maximum and minimum amounts of humidification in the figure (a decrease in the amount of humidification).
Δx is minimized, and uniform humidification control is performed.

According to the above embodiment, the following effects can be obtained.

(1) A humidification water supply pipe 40 for supplying humidification water to the humidification filter 47 is provided with a thermal opening / closing valve 44 which is opened / closed by ON / OFF control. When a signal is received, the thermal opening / closing valve 44 gradually reaches the fully opened state after the valve opening time T3. Accordingly, the humidification water supplied to the humidifying filter 47 gradually comes from the thermal opening / closing valve 44. Discharged. As a result, the thermal valve 4
4 can be suppressed, and the humidifying water can be supplied without the humidifying water scattered outside the vaporizing humidifier 45 including the humidifying filter 47.

(2) When the on / off valve 44 receives the ON signal in the fully closed state, the thermally operated on / off valve 44 gradually reaches the fully opened state after the valve opening time T3. The humidification water discharged from the dynamic on-off valve 44 gradually increases, and the overshoot from the thermal on-off valve 44 is suppressed, so that the humidification water can be conserved.

(3) When the thermal open / close valve 44 receives the OFF signal in the fully open state, the valve body of the thermal open / close valve 44 gradually reaches the fully closed state after the valve closing time T5, and the thermal open / close operation is performed. Since the amount of humidification water discharged from the valve 44 gradually decreases, the humidification water in the humidification filter 47 does not suddenly decrease and is not depleted.

(4) The thermal open / close valve 44 is maintained at the full open holding time T4.
, The amount of humidification water supplied to the humidification filter 47 increases during that time. For example, if the fully open retention time T4 is increased, the amount of humidification water supplied increases accordingly. Accordingly, the amount of humidification supplied to the room increases, and the maximum amount of humidification can be increased.

(5) Full-open hold time T4
, The energization time of the thermal valve 44 can be shortened, so that the full-open holding time T4 can be shortened as much as possible.

(6) Fully closed holding time T6 of the thermal valve 44
The humidifying water is not supplied to the humidifying filter 47 during that time. For example, if the fully closed holding time T6 is shortened, the reduction of the humidifying water in the humidifying filter 47 decreases accordingly. Along with this, it is possible to suppress a decrease in the amount of humidification supplied to the room.

(7) Since the thermal opening / closing valve 44 is opened and closed by ON-OFF control, the amount of humidified water injected from the thermal opening / closing valve 44 according to the opening / closing of the valve is as shown in FIG. 5B. Changes to a trapezoidal shape. Accordingly, the amount of humidification supplied to the room changes smoothly as shown by the solid line in FIG. 5C, and the difference between the maximum amount and the minimum amount of humidification (decrease in humidification amount) Δx in FIG. Minimized and uniform humidification control can be performed.

(8) Since the evaporative humidifier 45 is disposed on the secondary side of the heat exchanger 23 and between the heat exchanger 23 and the cross flow fan 26, it is heated by the heat exchanger 23. A sufficient humidification amount of, for example, 300 cc / h or more can be given to the air. In particular, the second and third heat exchange units 23
Since the evaporative humidifier 45 is inserted between B and 23C, the evaporative humidifier 45 is connected to each of the heat exchange units 23B and 23C.
After that, it is located at the junction of the warm air, so that the humidification efficiency can be further improved.

(9) Since the humidification water supplied to the humidification filter 47 is a part of the supply water supplied to the heat source unit 27, the humidification water evaporated by the humidification filter 47 is connected to the heat source unit 27 and the room. This is not clean water circulated between the hot water heat exchanger 24 but clean water (water supply) before being supplied to the heat source device 27. For this reason, even when the room is humidified by the humidification filter 47, the cleanliness of the room air can be kept good.

(10) Because the humidification water supply pipe 40 for supplying humidification water to the humidification filter 47 is disposed in contact with the hot water outflow pipe 29 and the hot water return pipe 30 connected to the indoor hot water heat exchanger 24. The humidification water supplied to the humidification filter 47 is heat-exchanged by the hot water in the hot water outgoing pipe 29 and the hot water return pipe 30 to increase the temperature. As a result, natural evaporation of the humidification water supplied to the humidification filter 47 is promoted, and the humidification of the room by the humidification filter 47 can be quickly performed.

(11) A humidification water pipe 53 for supplying warm water from the humidification water supply pipe 40 to the humidification filter 47 penetrates through the inside of the humidification tube 24B of the indoor hot water heat exchanger 24 and comes into contact with the humidification tube 24B. Since the humidifying water is supplied to the humidifying filter 47, the temperature of the humidifying water is further increased than the temperature of the humidifying water supplied to the humidifying water supply pipe 40 by the heat of the hot water flowing through the hot water heating tube 24 </ b> A of the indoor hot water heat exchanger 24. I do. As a result, the natural evaporation of the water supplied to the humidification filter 47 is promoted, and the humidification filter 47 can quickly humidify the room.

(12) Since the third heat exchange section 23C of the indoor refrigerant heat exchanger 23 is disposed so as to overlap the indoor hot water heat exchanger 24, the heat quantity of the third heat exchange section 23C is reduced by the indoor hot water heat exchanger. The temperature of the hot water transmitted to the humidification tube 24B and flowing through the humidification water pipe 53 penetrating the inside of the humidification tube further rises and is maintained. As a result, natural evaporation of the humidification water supplied to the humidification filter 47 is promoted, and the humidification of the room by the humidification filter 47 can be quickly performed.

Although the present invention has been described based on the above embodiment, the present invention is not limited to this.

For example, a gap is formed between the first heat exchanging section 23A and the second heat exchanging section 23B, and a vaporizing humidifier 4 is formed there.
5 may be inserted and arranged.

Although the humidification water supply pipe 40 has been described as being in contact with both the hot water outgoing pipe 29 and the hot water return pipe 30, it may be in contact with either one of the hot water outgoing pipe 29 and the hot water return pipe 30. . In the air conditioner 10, the hot water supply unit 13 has been described as being installed separately from the outdoor unit 11, but may be arranged inside the outdoor unit 11.

According to these inventions, when the open / close valve receives the open signal in the fully closed state, it gradually reaches the full open state after a predetermined time, and when the open / close valve receives the close signal in the fully open state, it gradually passes through the predetermined time. Since it is provided with a configuration that reaches the fully closed state, overshoot can be suppressed, and water saving of humidifying water can be achieved.
