JPH0623229A - Hygrostat - Google Patents

Abstract

PURPOSE:To provide a hygrostat which is simple to handle and healthy in order to dehumidify and humidify moisture in a room. CONSTITUTION:After air in a room is sucked in a hygroscopic material 7 consisting of a porous material from valve units 8, 9, 10, 11 by turning and driving fans 4a, 4b with motors 5a, 5b to adsorb moisture contained in air, motors 5a and 5b are switched over by a switch to change the direction of air flowing, an air intake port and an exhaust air port are switched over. When warm air is delivered to a hygroscopic material 7 from an electrified, controlled heater, moisture is desorbed from the hygroscopic material to regenerate hygroscopic capacity and simultaneously, moisture-contg. air is discharged outside the hygrostat to humidify or dehumidify moisture in a room. At this time, since an air window of a valve seat 14 fitted to each valve unit is provided with a fence, the deformation of a light and thin valve 16 is prevented and the backflow of air is prevented, changeover switch operation is facilitated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidity controller using a hygroscopic material.

[0002]

2. Description of the Related Art A conventional dehumidifier has a dedicated device for dehumidifying only and a humidifier for humidifying only. The respective units are controlled to adjust the humidity of a room.

[0003]

However, it is difficult to control switching and stopping operation by independently controlling those devices and adjusting the humidity of the room to a target humidity. Further, even when remote control is desired, a separate control operation is required, and the combination of control operations is complicated.

DISCLOSURE OF THE INVENTION The present invention relates to a hygroscopic material having a property of adsorbing moisture in the air, and an air for dehumidifying it by adsorbing a certain amount of moisture to the hygroscopic material and then passing it through hot air at high temperature. Heaters are placed before and after the hygroscopic material, and two blowers for sucking in the air inside and outside the room are built in, and there are four air intake and exhaust openings inside the room. It is equipped with a one-way valve that allows air to pass through in only one direction, and as a dehumidifying / humidifying / humidifying device, it has a switch that switches between dehumidifying operation and humidifying operation, and controls the power supply to the heater and blower to pass the air blowing direction and the hygroscopic material. The dehumidifying operation and the humidifying operation are performed according to the change in the temperature of the generated air.

First, in the dehumidifying operation, the first blower is operated for a certain period of time to suck the air in the room from the intake port, and the air is sucked in the order of the first heater, the moisture absorbent, the second heater, and the second blower. Pass it through and spit it back into the room through the spout.

At this time, neither heater is energized, so that the air at room temperature passes through the hygroscopic material, moisture in the air is adsorbed, and dried air is returned to the room.

Next, when the first blower is stopped and at the same time the second blower, which blows air in the opposite direction to the first blower, is operated for a certain period of time, this time the air outside the room is taken in and the second heater, Air is sent into the air flow path that is lined up with the hygroscopic material, the first heater, and the first blower, and returned to the outside of the room through the outlet.

At this time, when the second heater is energized, the temperature of the air becomes high in front of the hygroscopic material, and when it passes through the hygroscopic material, the moisture adsorbed from the air in the room is desorbed and released.
It becomes high-humidity air and is carried away from the room. The two types of switch switching operation are alternately and repeatedly controlled to dehumidify the humidity in the room.

Next, when switching from the dehumidifying operation to the humidifying operation with a remote control switch or a manual switch, the first blower is operated to take in the air in the room, pass through the inside of the device, and return to the room again. I decided to energize the first heater,

Further, in order to operate the second blower to take in the air outside the room, pass it through the inside of the device and return it to the outside of the room again, neither the first heater nor the second heater is energized. The moisture absorbent adsorbs the moisture content of the air outside the room and releases it to the air inside the room, so that the room can be humidified. Further, a humidity detector for detecting the humidity is provided, and the direction of the air blow and the energization to the heater are controlled so that the humidity is set by comparing with the set humidity by the comparison circuit. The blower does not need the first and second blowers, and the direction of the blow may be controlled by switching the rotation direction.

1 is a front view (a) and a side view (b) of a humidity controller of the present invention, and FIG. 2 is a sectional view taken along the line A--A. The main body case 2 includes motors 5a and 5b for rotating the blower fans 4a and 4b and a heater 6a,
6b are respectively installed with the hygroscopic material 7 in between,
The moisture adsorbed on the air is heated by the heater 6a or 6b to be released.

Branch pipes 3a and 3b are inserted and fitted on both sides of the main body case 2. Valve units 8, 9, 10, and 11 are rotatably attached to the branch pipes 3a and 3b, respectively.
It is inserted and attached to both ends of a and 3b. The valve units 8, 9, 10 and 11 have valve seats 14 attached to the valve pipes 13 having grilles 12 in the form of lattices from the rear with screws 15a and 15b.
6 is attached to the holes 17a and 17b with screws 18a and 18b.

The indoor air inlet B and outlet C of the humidity controller 1 and the outdoor air inlet D and outlet E outside the partition wall 21 are provided. When the motor 5a is rotated, the fan 4a also rotates, Therefore, when air is blown in the direction of the arrow F, the inside of the humidity controller of the valve units 8 and 11 becomes a negative pressure, so that air is sucked from the outside of the humidity controller 1. At this time, the valve unit 11 has a thin film valve 16 made of rubber as shown in the rear view in FIG. , 1 screw on 17b
Since it is stopped by 8a and 18b and droops, it is pressed against the valve seat 14 and closes the window 20 of the valve seat 14.

The window 20 of the valve seat 14 is vertically provided with a fence 19 integrally therewith, which prevents the valve 16 from being excessively deformed and passing over the window 20 even though the valve 16 is a thin film. As a result, a sufficient close contact with the valve seat 14 can be maintained in blocking the flow of air.

The valve unit 8 has a valve 16 in the inside of the humidity controller of the valve seat 14 in the holes 17a and 17b of the valve seat 14 as shown in the sectional view of FIG. Screw 18
Since it is stopped by a and 18b and droops, the valve 16 is pushed inward like a goodwill by the pressure difference between the atmospheric pressure outside the humidity controller 1 and the negative pressure inside the humidity controller 1. Can breathe air in the room.

Further, the humidity controller 1 of the valve units 9 and 10 on the other side
Since the inner side of the valve has a positive pressure, each valve 16 of the valve units 9 and 10 receives a force that tends to be pushed outward, and in the valve unit 10, the valve seat 14 is provided outside the valve 16.
Since the window 20 is provided with the fence 19 to block the flow of air, the valve unit 9 on one side pushes the valve 16 outward to expel the air into the room.

In this way, the direction of the air blown by the arrow F is B
Can be inhaled from C and exhaled to C, and leakage from E and D can be prevented by keeping the thin film valve 16 in close contact with the fence 19 provided on the window 20 of the valve seat 14. To be done.

Next, the motor 5a is switched by switching the switch.
When the fan 4a is stopped from rotating, the motor 5b is simultaneously supplied to rotate the fan 4b, the direction of the air blow is in the direction of the arrow G, and the valve units 8, 9, 10, 11 are in only one direction, respectively. Because it is a one-way valve that allows ventilation, it can inhale from D and expel to E, and
There is no inhalation leakage from B or exhalation leakage to B.

Now, description will be made on the case where the dehumidifying operation and humidifying operation changeover switch provided in the controller (not shown) is set to the dehumidifying operation side to dehumidify the inside of the room, and the case where the humidifying operation side is set to humidify the room. To do.

First, when the dehumidifying operation is performed, the motor 5a and the fan 4a are rotated for a certain period of time to suck the air in the room from the suction port B, and the moisture in the air is adsorbed by the adsorbent 7 while passing through the adsorbent 7. Then, it is made into dry air and returned to the room through the outlet C. At this time, neither of the heaters 6a and 6b is energized.

Next, in order to restore the capacity of the hygroscopic material, the motor 5a and the fan 4a are stopped, and the motor 5b and the fan 4b are rotated to suck the outdoor air from the suction port D and at the same time energize the heater 6b, Since the air sucked from outside the room before the moisture absorbent 7 becomes hot and passes through the moisture absorbent 7, the moisture in the room that the moisture absorbent 7 adsorbs and holds is desorbed (released) to a high humidity. It becomes air and is returned from the outlet E to the outside again.

A regeneration operation for recovering the capacity of the moisture absorbent 7 is performed for a certain period of time to complete one cycle of operation.
By repeating this moisture absorption and regeneration alternately, the moisture in the room is carried out to the outside through the moisture absorbent 7 to dehumidify the room.

When the changeover switch is switched to the humidifying operation side, the motor 5a is first supplied with power for a certain period of time to rotate the fan 4a to suck air in the room, as described above. At this time, when the heater 6a is energized, the hygroscopic material is absorbed. Dehumidify (release moisture) the moisture of 7 to make high humidity air and return it to the room again.

Next, when the power supply to the motor 5a is stopped and the fan 4a is stopped, and the motor 5b is supplied for a certain period of time to rotate the fan 4b, the outdoor air is sucked in, and the heaters 6a and 6b are not energized. The moisture of the air is absorbed.

By repeating this alternately, contrary to the dehumidifying operation, the moisture content of the outdoor air can be carried into the indoor air through the adsorbent 7, so that the indoor space can be humidified.

The vertical fence 19 integrated with the valve seat 14 for keeping the valve 16 and the valve seat 14 in close contact with each other to prevent leakage fully exhibits the same function regardless of whether it is horizontal or grid. It was also confirmed experimentally.

Further, the valve units 8, 9, 10, 11 are not only in the horizontal state shown in FIG. 1 but also in the vertical state because the valve pipe 13 is rotatably incorporated in the branch pipes 3a, 3b. Also, each of the four valve units is rotated in the same direction by 90 ° to attach the valve 16 to the valve seat 14 with a screw 1
The function can be exhibited by making the 8a and 18b sides the top side.

Although two motors are used, it can be easily inferred that the present invention can be realized even if the direction of the air blow is reversed by one DC motor for normal rotation and reverse rotation. Further, the timing of the energization switching switch between the motor and the heater is controlled by the microcomputer and the switching is easily established, so that it is stable against repeated switching operations.

[0029]

As described above, the simple operation of simply switching the switch of the present invention enables dehumidification and humidification with a single unit and, in principle, does not require a water tank. It can be used as a humidifier and can be used all year round.
