Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a household dehumidifying device that uses a dehumidifying material, and particularly to a dehumidifying unit that permanently dries a plurality of independent spaces.

Conventional technology Conventionally, drying of utility spaces such as cupboards, storage areas of system kitchens, and closets has been carried out using a static drying method in which a moisture absorbent such as lithium chloride or silica gel is sealed in a container and placed in the space to be dried. It was held in

Problems to be Solved by the Invention The static method of individually installing moisture absorbents in the space to be dried has the following problems.

(1) Since it adsorbs only the moisture floating in the air due to natural diffusion, the amount of moisture absorbed per hour is only a few grams, and the dehumidification ability is low, so it is almost impossible to dehumidify in a storage compartment that is frequently opened and closed.

(2) Since a fixed amount of moisture-absorbing material is placed individually in each space to be dried, it is not possible to dehumidify in response to the dehumidification load, and it is difficult to always create a stable drying atmosphere. Further, it is troublesome that it is necessary to visually check whether the moisture absorption limit has been reached.

The present invention solves the above problems, and aims to provide a dehumidification unit that can permanently dry multiple independent spaces and intensively dehumidify spaces with a high dehumidification load. There is.

Means for Solving the Problems A dehumidifying section comprising a dehumidifying material, a heat source device, a blower, a controller, an inlet and an outlet, and a plurality of units directly connected to the dehumidifying section and each having an inlet and an outlet. The dehumidifier includes a communication pipe, an exhaust duct that discharges moisture from the dehumidification material, and a humidity sensor that outputs a signal to the controller, and the dehumidification unit is disposed in a space with the highest dehumidification load, and the communication pipe The inlet and outlet of
It is arranged in a dehumidifying space other than the above-mentioned space.

Furthermore, a damper that opens and closes depending on the humidity detected by the humidity sensor is disposed within the communication pipe.

Further, the moisture absorbing operation is performed for a predetermined period of time by detecting the humidity of the humidity sensor, and subsequently, the moisture absorbing material is dehumidified for a predetermined period of time by heating the heat source device.

Function: With the above-described configuration, the present invention can permanently dry a plurality of independent spaces using the dehumidifying section and the plurality of communicating pipes directly connected to the dehumidifying section.

Furthermore, since the dehumidifying section is disposed in a space with a high dehumidification load, this space can be intensively dehumidified. In this intensive dehumidification, the damper in the communication pipe is closed according to the humidity detection value of the dehumidification sensor, so that spaces with a high dehumidification load can be more quickly and intensively removed.

Since moisture absorption and desorption operation is performed for a predetermined period of time based on the humidity value detected by the humidity sensor, a stable dehumidification ability can always be obtained.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. As shown in FIG. 2, the dehumidifying unit 1 includes a dehumidifying material 2 formed into a corrugated shape, a heat source device 3 with a built-in electric heater disposed downstream of the dehumidifying material 2, and a heat source device 3 disposed downstream of the heat source device 3. A controller 5 that controls the heat source device 3, the blower 4, and a damper 8 (to be described later) using the information from the humidity sensor 13 that is installed in the space where the dehumidifier 1 is installed, and the air blower 4 that is installed. 6, a blowout lower, and an exhaust duct 12 in which a damper 80 is disposed,
As shown in the figure, the humidity sensor 13 and the humidity sensor 13 are arranged in a space with a high dehumidification load, such as under the sink Sc of the system kitchen S, for example.

One end of the plurality of communication pipes 11 is connected to the dehumidifying section 1.
One end of the outlet passage 15 communicates with the blowout lower, and the other end of the inlet passage 14 communicates with the suction opening 9 .
However, a blowout port 10 is formed at the other end of the outflow path 15, respectively. In addition, the inflow path 14 and the outflow path 1 of the communication pipe II
Dampers 8a, 8b8c, and 8d are disposed at the dampers 5, respectively. This communication pipe 11 is arranged to dehumidify the storage areas Sa and st+ of the system kitchen S, and its inlet 9 and outlet 10 are connected to the storage areas Sa, st+, respectively.
It faces the space of Sb.

The operation in the above configuration will be explained.

First, when the space Sc under the sink of the system kitchen S reaches a predetermined value higher than the humidity of the kitchen, the humidity sensor 1
3 detects the value and sends a signal to the controller 5. Based on this signal, the controller 5 operates the blower 4,
From the space Sc, from the suction port 6 of the dehumidifying section 1, to the space Sa.
, Sb through the suction port 9 of the communication pipe 11 and blows it to the dehumidifying material 2. The air dehumidified by the dehumidifying material 2 becomes dry air and is sent to the lower air outlet of the dehumidifying section 1 and the communication pipe 1.
The air is blown out from the air outlet 10 of 1 into each space Sa and 5bSc. At this time, the damper 8a.

8b, '8c, and 8d, and the damper 88 is closed. The blower 4 is operated for a predetermined period of time by a controller 5 based on the value detected by the humidity sensor 13. After this predetermined time has elapsed, the damper 8e of the exhaust duct is opened and the electric heater of the heat source device 3 is energized, and the moisture adsorbed by the dehumidifying material 2 is released and exhausted from the exhaust duct. At this time, all or part of the dampers 8a8b8c and 8d of the communication pipe 11 may be closed if necessary.

This release of moisture from the dehumidifying material 2, that is, heating, is performed for a predetermined period of time under the control of the controller 5.

Next, when the space Sc under the sink of the system kitchen S reaches a value considerably higher than the humidity of the kitchen, the humidity sensor 13
detects the value and sends a signal to the controller 5. Based on this signal, the controller 5 determines that the humidity in the space Sc is abnormally high, and dampers 8a, 8b, 8 of the communication pipe 11
All of c and 8d and the damper 80 of the exhaust duct are closed, and the blower 4 is operated to suck air from the suction port 6 of the dehumidifying section 1 and blow out dry air from the blowout lower. By this operation, the space Sc under the sink is intensively dehumidified. This dehumidification operation is carried out for a predetermined period of time in the same manner as described above. Furthermore, the subsequent heating and release of moisture from the dehumidifying material 2 is performed in the same manner as described above.

Note that the dehumidifying operation time controlled by the controller 5 and the time for heating and releasing moisture from the moisture absorbing material 2 can be changed according to the value detected by the humidity sensor 13.

As described above, according to the dehumidifying unit of the embodiment of the present invention, the dehumidifying section 1 is arranged in a space with a high dehumidifying load, for example, the space Sc under the sink of the system kitchen S, and the suction port 9 of the communication pipe 11, The air outlet IO is arranged in a dehumidifying space other than a space with a high dehumidifying load, for example, each storage part Sa, Sb, and dampers 8a, 8b, 8c are installed in the communication pipe 11 to open and close according to the detected value of the dehumidifying sensor 13. , 8d are installed, each space Sa, Sb, Sc is dehumidified based on the space with a high dehumidification load, and furthermore, when a space Sc with a high dehumidification load becomes abnormally high humidity, that space Sc is concentrated. can be dehumidified.

Furthermore, since the predetermined dehumidifying operation time of the dehumidifying section 1 and the predetermined operating time for heating and releasing moisture from the dehumidifying material are changed according to the detected value of the dehumidifying sensor 13, stable and reliable dehumidification can be performed according to the dehumidifying load. I can do it.

As is clear from the description of Embodiment ' above, according to the present invention, the dehumidifying section is arranged in a space with a high dehumidification load, and the inlet and outlet of the communication pipe are arranged in a space other than the space. A damper that opens and closes according to the detection value of the dehumidification sensor is installed in the communication pipe, and the predetermined dehumidification operation time and the predetermined operation time for heating and releasing moisture from the dehumidifying material are changed depending on the detection value of the humidity sensor. By doing so, it is possible to provide a dehumidification unit that can permanently dry a plurality of independent spaces and can intensively dehumidify spaces with a high dehumidification load.
