Abstract

PROBLEM TO BE SOLVED: To perform a highly efficient operation by controlling an adsorption time and a regenerative time according to a signal of an air state detecting means for detecting temperature and humidity of dehumidified air before processing. SOLUTION: Inside or in the vicinity of an air inlet 4 for dehumidification is installed an air state detecting means 11 for detecting temperature and humidity of air before entering a dehumidifier. Information of the air state detecting means 11 is transmitted to a control means 12. The control means 12 compares the quantity of water operated from temperature and humidity in a bathroom detected by the air state detecting means 11 with the quantity of water set inside, and sets a time used for a regeneration process according to a difference thereof. Namely, in the case the quantity of water is less than a set value, a shorter execution time of a regenerative process is set, and in the case the quantity of water is more than the set value, a longer execution time of regenerative process. Conversely, a similar effect is obtained by changing the time for adsorption process according to the quantity of water contained in the air in the bathroom.

[0011]

(Embodiment 1) Hereinafter, a dehumidifier according to a first embodiment of the present invention will be described. FIG. 1 is a sectional view showing the configuration of the present embodiment.

An adsorbent 2 for adsorbing moisture is provided in a main body 1.
Heating means 3 for desorbing moisture adsorbed by adsorbent 2;
The apparatus includes a blower 7 for blowing dehumidified air and regeneration air, an air passage switching damper 8, and a control unit 12 for controlling each unit. The adsorbent 2 and the heating means 3 constitute a dehumidifying means for dehumidifying the air in the bathroom. The surface of the main body 1 is connected to a dehumidifying air inlet 4 for sucking dehumidified air in the bathroom, a dehumidifying outlet 5 for discharging dehumidified air into the bathroom, and an outdoor for discharging air after regeneration. And a reproduction discharge port 6. As the adsorbent 2, silica gel or zeolite is used. As the heating means 3, a heater is used. Further, in this embodiment, the air condition detecting means 11 is attached inside or near the dehumidifying intake port 4. That is, the air condition detecting means 11 detects the temperature and humidity of the dehumidified air before entering the dehumidifying device, and includes a temperature sensor using a thermistor and a humidity sensor for detecting humidity. The information of the air condition detecting means 11 is as follows:
It is transmitted to the control means 12.

The operation of this embodiment will be described below. When a switch (not shown) is turned on, the apparatus of this embodiment mounted on the ceiling of a bathroom or the like starts operating. That is, the blower 7 starts to rotate, draws air in the bathroom from the dehumidifying air inlet 4, and blows the inside of the main body 1. Further, the dehumidification discharge port 5 is opened and the reproduction discharge port 6 is closed with the air path switching damper 8 as the a side. Therefore, the main body 1 is provided with a blowing path from the blower 7 to the dehumidification discharge port 5,
An adsorbent 2 is provided in this air blowing path.
The moisture in the blown air is adsorbed by the adsorbent 2.
The blown air from which moisture has been removed and dried is blown into the bathroom from the dehumidification discharge port 5. The dry air blown from the dehumidification discharge port 5 circulates in the bathroom and returns to the dehumidification intake port 4 again.
And dried by the adsorbent 2. By performing this adsorption step, dehumidification of the air in the bathroom proceeds.

As described above, when the adsorbed amount of the adsorbent 2 approaches saturation, the control means 12 executes the regeneration step as described in the conventional example. That is, the dehumidification discharge port 5 is closed, and the regeneration discharge port 6 is opened with the air path switching damper 8 as the b side. At the same time, the heating means 3 is energized to raise the temperature of the air in contact with the adsorbent 2 to a high temperature. When the blower 7 is operated in this state, the dehumidifying suction port 4 functions as a regeneration suction port for sucking air for regenerating the adsorbent 2, and the air blown by the blower 7 contacts the adsorbent 2 via the heating means 3. Things.
In FIG. 1, the regeneration intake port is represented as 10. When the high-temperature air comes into contact with the adsorbent 2 in this way, the adsorbent 2 releases the adsorbed moisture and is regenerated. The moisture released from the adsorbent 2 is supplied to the air path switching damper 8.
Is on the b side, and is discharged from the reproduction discharge port 6 connected to the outdoors. When the regeneration of the adsorbent 2 is completed in this way, the control means 12 stops the energization to the heating means 3 and executes the adsorption step with the air path switching damper 8 as the a side.

At this time, in this embodiment, information on the temperature and humidity of the air in the bathroom detected by the air condition detecting means 11 is transmitted to the control means 12. The control means 12 determines the time for executing the regeneration step by comparing the information of the temperature and the humidity with the reference set therein. For example, if the setting of the execution time of the conventional reproduction process is 1, the setting is changed to 0.5 to 1.5. The width of 0.5 to 1.5 is determined according to the difference between the temperature and humidity of the air in the bathroom detected by the air condition detecting means 11 and a reference value set inside. .

That is, when the air in the bathroom contains a large amount of water, the amount of water adsorbed by the adsorbent 2 naturally increases. Therefore, the time required until the adsorbent 2 is regenerated becomes longer. When the amount of water contained in the air in the bathroom is small, the amount of water adsorbed by the adsorbent 2 is naturally small. Therefore, adsorbent 2
However, the time required until the file is reproduced becomes shorter. Therefore, in the present embodiment, the control unit 12 compares the moisture amount calculated from the temperature and humidity in the bathroom detected by the air condition detecting unit 11 with the moisture amount set inside, and according to the difference, The time required for the reproduction process is set to 0.5 to 1.5. That is, when the moisture content is smaller than the set value, the execution time of the regeneration process is set shorter, and when the moisture content is larger than the set value, the execution time of the regeneration process is set longer.

Further, the execution time of the regeneration step is not changed in accordance with the amount of water contained in the air in the bathroom, but the time in the bathroom has the time required for the adsorption step. The same effect can be obtained even if it is changed according to the amount of water. That is, when the execution time of the conventional adsorption step is set to 1, the execution time of the adsorption step is set to 0.5.
To 1.5. That is, when the water content is larger than the set value, the execution time of the adsorption step is shortened, and when the water content is smaller than the set value, the execution time of the adsorption step is set longer, so that the adsorbent 2 is adsorbed. It is to keep the amount of water to be made constant.

As described above, according to this embodiment, the air condition detecting means 1 for detecting the temperature and humidity of the dehumidified air in the bathroom.
By controlling the adsorption time and the regeneration time in accordance with the signal No. 1, it is possible to realize a dehumidifier capable of operating with high efficiency.

As described in the first embodiment, according to the detection information of the air condition detection unit 11,
When the control means 12 grasps the moisture content of the air in the bathroom, in the present embodiment, the amount of electricity to the heating means 3 during the regeneration process is adjusted according to the moisture content. That is, the amount of heat generated by the heating means 3 is adjusted while keeping the time required for the regeneration process constant. For example, when the heating value of the conventional heating means 3 is set to 1, in the present embodiment, the heating value is adjusted to be 0.5 to 1.5. The amount of heat generated at this time can be grasped from the temperature detected by the temperature detecting means 13. That is, when the moisture content is larger than the set value, the set value of the calorific value is set higher, and when the moisture content is smaller than the set value, the set value of the calorific value is set lower.
Even if the time required for the reproduction process is constant, sufficient reproduction can be performed.

At this time, in this embodiment, the control unit 12 monitors the regeneration temperature by the temperature detection unit 13 at the same time, and controls the detected temperature of the temperature detection unit 13 to maintain a predetermined value. When the amount of moisture contained in the air in the bathroom is small, the air volume of the blower 7 is reduced. Of course, also in this case, control is performed so that the temperature detected by the temperature detecting means 13 maintains a predetermined value.
