Abstract

PURPOSE:To perform a fast drying of a humidifying plate or around a gasification type humidifier device after stopping of the humidifier device and prevent mold from being generated at a place where a high humidity is found by a method wherein after the humidifier installed at a downstream side of an air supplying air blower, the air supplying air blower is operated for a predetermined period of time. CONSTITUTION:When a switch 119 is set to a B side 19b, a power supply for a solenoid valve 118 is turned off to close the solenoid valve, resulting in that a water supplying to a gasification type humidifier 117 is stopped and a humidification is not carried out. A timer 120 is impressed to cause a contact point C120c of the timer 120 to be kept on for a predetermined period of time, a power supply is also applied a relay 121, a contact point D121d cooperated with the relay 121 is turned on, a contact point E121e is turned off, the air supplying air blower 113 is applied with the power supply and operated and then the air blowing is continued to cause the humidifier 117 to be gradually dried. After this operation, as the predetermined period of time set by the timer 120 elapses, as the predetermined period of time set by the timer 120 elapses, the contact point C120c is turned off, the air supplying air blower 113 has not application of the power supply and then the air blowing is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner incorporating a humidifier.

2. Description of the Related Art Conventionally, this type of air conditioner has a built-in humidifier to prevent the indoor air from drying out due to heating, and as shown in FIGS. An air supply blower 3 installed in the air supply passage 2 that supplies air into the room, and a vertically standing wall in the frame 4 on the leeward side of this air supply blower 3,
An evaporative humidifier 7 formed of a large number of humidifying plates 6 facing the upper water tank 5 is provided. Reference numeral 8 denotes a solenoid valve for controlling the water supply to the water supply tank 5, and the solenoid valve 8 opens at the same time as the air supply blower 3 operates to supply water to the water supply tank 5.
Moisture is transmitted to the humidifying plates 6, humidifying the air blown by the air supply blower 3 passing between the humidifying plates 6, and blowing the humidified air into the room. On the other hand, at the same time as the air supply blower 3 stops, the solenoid valve 8 closes, water supply to the water tank 5 stops, and humidification also stops.Problems to be Solved by the Invention Such a conventional configuration In this case, at the same time as the operation of the air supply blower 3 is stopped, the solenoid valve 8 is closed and the water supply to the water tank 5 is stopped.
Since there is no air blowing around the humidifier, the humidifier takes a long time to dry naturally, so it easily attracts dust and is unhygienic.

The present invention solves these problems, and aims to quickly dry the humidifying plate and the surrounding area of the evaporative humidifier after the evaporative humidifier is stopped, thereby preventing mold, etc. that tend to grow in high humidity areas. It is something to do.

Means for Solving the Problems In order to solve this problem, the present invention provides an air supply blower in the air supply passage that supplies air into the room, and a humidification device on the downwind side of the air supply blower. The air supply blower is configured to operate for a predetermined period of time after the apparatus is stopped.

Effect: With this configuration, after the humidifier stops, the air supply blower operates for a predetermined period of time and blows air around the humidifier plate and humidifier that contain moisture, which quickly dries them and prevents the growth of mold, etc. becomes.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 5.

In FIGS. 1 and 2, 101 is the main body of the air conditioner, for example, an indoor suction port 102 and an indoor discharge port 103 communicating with the room are provided, and an outdoor suction port communicating with the outdoors is provided on the other side. A port 104 and an outdoor discharge port 105 are provided. The air passage surface 106 inside the main body 10]
Heat exchanger 1 in the shape of a rectangular prism tilted at 45 degrees with respect to the horizontal plane
07 is provided. In the exhaust passage 108 that exhausts indoor air to the outdoors, a coarse dust filter 109 is installed downstream of the heat exchanger 107, and an exhaust fan 110 is installed upstream. air passage 111
A medium-performance filter 112 is installed downstream of the heat exchanger 107.
Also, on the upstream side is a supply air blower 113, and on the leeward side of this supply air blower 113 is an evaporative humidifier 117.
The evaporative humidifying device 117 is vertically arranged within the frame 114 and is formed of a large number of humidifying plates 116 facing the water tank 115 above. 118 is the water tank 115
This is a solenoid valve that controls the water supply to. The operation of the evaporative humidifying device 117 is as shown in the circuit diagram of FIG.
Power is applied to the solenoid valve 118, the air supply blower 113 blows air, the solenoid valve 118 is opened, and the evaporative humidifier 11
7 will be supplied with water and humidified. Next, as shown in the circuit diagram of FIG. 4, when the switch 119 is turned to the B side 119b, the power to the solenoid valve 118 is cut off and the valve is closed, water supply to the evaporative humidifier 117 is stopped and no humidification occurs, but the timer 120 for a predetermined period of time.
0 contact C120c remains closed, and relay 121
Power is also applied to the contact D1 which is linked to the relay 121.
21d is turned on, the contact E121e is cut off, and the air supply blower 113 is operated with power applied to it and continues blowing air, thereby gradually drying the humidifying device 117. After that, when the predetermined time set by the timer 120 has passed, as shown in the circuit diagram of FIG. E121e is turned on, power is no longer applied to the air supply blower 113, and air blowing is stopped.

As described above, according to this embodiment, even if the switch 119 is switched to the B side 119b and the solenoid valve 118 that stops the water supply to the evaporative humidifying device 117 is closed, the timer 120 causes the humidifying plate 116 and the evaporative humidifier to The air supply blower 113 is operated for a predetermined period of time necessary to dry the area around the humidifier 117 with air, and the air continues to be blown, so that mold and the like can be prevented from forming in the humidifier 117.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, even if the power is turned off and the operation of the humidifier is stopped, that is, the water supply is stopped by closing the valve, the water supply necessary for drying the humidifier and its surroundings is maintained. The air supply blower operates for a specified period of time, which prevents mold and other problems that tend to grow in humid areas.If the humidifier is left damp, dust tends to adhere to it and the lifespan of the humidifier plate is shortened. By continuing to operate the humidifier to dry it even after it is stopped, the adhesion of dust is reduced and durability is improved.
