Description

  The present invention relates to a humidifier that evaporates moisture held in a humidifying filter and humidifies air, and control of an electrical appliance having a function that combines an air cleaning function and a dehumidifying function.

  In recent years, the pursuit of comfort in the air quality at home and in the workplace has increased, mainly to prevent dryness (increase humidity) during winter heating as well as temperature adjustment, removal of air stains, and reduction of moisture during the rainy season. Humidification is required.

  In response to such demands, there is a method of humidifying by vaporizing moisture with ultrasonic waves or a heater, but in recent years there has been a demand for energy saving etc. and a function to release moisture into the air and humidify it after holding moisture once. Vaporizing humidifiers are increasing due to the improvement of the ability of humidifying filters. Of course, these humidifiers are also used in combination with a heater or the like to improve the humidification ability.

  Conventionally, water supplied to the humidifying filter in such a humidifying device is stored in a water tray, and the humidifying filter absorbs the water, and the moisture absorbed by the air blown to the humidifying filter is released to humidify the water. Has been done.

  The water tray needs to be deep enough to immerse the humidifying filter in the water tray depending on the shape of the humidifying filter. At the same time, the depth is determined by the shape of the humidifying filter. Will follow the size of the bottom area of the water tray. However, increasing the bottom area of the water tray is nothing but increasing the bottom area of the humidifier body, and there are limits to this option in consideration of recent housing conditions.

  As another method for increasing the amount of water, there are a method in which a separate water tank that can supply water to the water tray is attached, and a system in which the water can be supplied from a water supply via a stop cock. (For example, refer to Patent Document 1 and Patent Document 2).

  As an example, as shown in FIG. 5, the humidifier 101 passes through a suction port 102 that takes in air from outside the device and a humidifying filter 103, and a fan 105 that sends out the humidified air from the outlet 104 to the outside of the device. And a water tray 107 for supplying water to the humidifying filter 103.

  In addition, the humidifying filter 103 has a cylindrical shape, and can retain moisture by immersing it in a water tray around the cylindrical portion and release the retained moisture into the air. It is assumed that a filter is provided and a small motor for rotating the cylinder is also provided. Polyester or the like can be used as a material for the cylindrical filter.

  In the case of this example, since the humidification filter 103 operates by absorbing the water 108, the water surface 109 decreases as the water 108 decreases with the operation. The humidifying filter 103 cannot absorb the water 108 by lowering the water surface 109 as it is operated. Further, since the depth of the water tray 107 depends on the immersion depth of the humidifying filter 103, there is no effect even if the water storage amount is increased to a certain depth or more.

Therefore, a water tank for replenishing water and a water supply pipe from clean water are necessary. As an example, as a general form, a water tank 110 is provided in the humidifying device 101, and the water in the water tank 111 is utilized by utilizing the difference in atmospheric pressure between the water surface 109 of the water 108 and the water surface 112 in the water tank 107. The water can be replenished when the water 108 in the water tray 107 decreases through the water tank water supply valve 113.

A filter element 13 is formed and provided as a water retaining means for discharging to the water, and a small motor for rotating the cylindrical central axis in a horizontal direction is provided. That is, the humidifying filter 3 is a filter element 13 that is formed in a cylindrical shape as water retaining means and disposed in the air flow path. Further, the filter element 13 is configured such that the cylindrical central axis is disposed in the horizontal direction and is driven to rotate by a small motor 13a as a rotating means.

  The configuration of the humidifying filter 3 will be described with reference to FIG.

  As shown in FIG. 2, the filter element 13 of the humidifying filter 3 uses polyester as a material having a function of absorbing water by being immersed in water 8 and releasing moisture by blowing air from the fan 5. Then, a cylindrical shape is formed by circular side supports 14 provided on both side surfaces and a skeleton (not shown) connecting the side supports 14, and the humidifying filter 3 is formed by holding the filter element 13 on the outer periphery thereof. Further, a filter shaft 15 arranged in accordance with the center of the side support 14 and a motor bearing 16 which is a bearing of the small motor 13a connected to the shaft are provided.

  Further, on the upper side of the humidifying filter 3 configured as described above, there is a humidifying filter vertical moving device 12 that is a vertical moving means for suspending the humidifying filter 3 and moving the position in the water tray 7 up and down. Is provided.

  Moreover, the water tray 7 is located in the bottom face part of the humidification apparatus 1, and the humidification filter 3, the fan 5, the motor 6, the small motor 13a, the control apparatus 11, and the humidification filter vertical movement apparatus 12 are arrange | positioned in the upper part. To do.

  With the above configuration, the water tray 7 contains water 8 up to a predetermined position, and the filter element 13 of the humidifying filter 3 is immersed in the water surface 9. The filter element 13 is fixed at a position where a part of the circumference formed in the cylinder is immersed.

  When the humidifying device 1 is operated, the fan 5 is driven by the motor 6 by the action of the control device 11, and air is sucked from the suction port 2 and passes through the humidifying filter 3. At this time, the humidifying filter 3 is rotated slowly by the small motor 13a, absorbs water by the filter element 13 in the water tray 7, and releases moisture by being brought into contact with the air passing through the air passage. Become. And this air is further conveyed by the blower outlet 4, and will be blown out from the upper surface of an apparatus.

  In other words, the humidifying filter 3 is rotated by the small motor 13a through the motor bearing 16, thereby repeating the immersion of the filter element 13 into the water 8, the absorption of the water, the movement to the air passage, and the release of moisture. Realized.

  However, the water 8 stored in the water tray 7 decreases as the operating time of the humidifying device 1 advances, and the water surface 9 becomes lower than the humidifying filter 3. When the water surface 9 is lowered, the water 8 cannot be absorbed by the filter element 13.

  So, in this Embodiment, the water level detection apparatus 10 detects the water surface 9, and the control apparatus 11 which received the signal drives the humidification filter vertical movement apparatus 12, and sets the height position of the humidification filter 3 to the water surface. It will be adjusted to 9. In this way, by always immersing the filter element 13 of the humidifying filter 3 with respect to the water surface 9 at a constant height, the humidifying device 1 can be operated while keeping the humidifying amount at a predetermined amount. .

  The humidifying filter 3 may have a disk shape in which a filter element is formed in a disk shape, a filter shaft and a motor bearing are provided concentrically at the center thereof, and the filter element is rotated.

  Moreover, as an example of the water level detection device 10 for detecting the water level, a detection device using a simple float as shown in FIG. 1 or an electrode system using a difference in electric conductivity between water and air can be generally used. . In this case, by installing multiple floats and electrodes at different heights in the direction of the water level, multiple levels of water level detection can be easily performed, and the control device determines the position of the humidifying filter 3 accordingly. It can also be moved up and down in multiple stages. (The figure is omitted.)

  In addition, as an example of means for raising and lowering the humidifying filter portion, it is common to use a stepping motor that can control the rotation angle by sending an arbitrary pulse from the control device. A rack and pinion gear system using a pinion gear and a rack gear on the side to be moved up and down can be used. (The figure is omitted).

  Further, by providing a humidity sensor 17 in the vicinity of the air inlet side of the air passage, the humidity of the indoor environment in which the humidifier is installed is detected, and when the controller 11 reaches a certain humidity, the motor is operated. The humidification operation can be stopped by stopping the operation.

  As the air purification filter, in addition to a commercially available high-performance filter for air purifier generally called HEPA or ULPA, a filter to which a functional component such as catechin is added can be used depending on the purpose.

  Further, when it is determined that the humidification operation is unnecessary based on the detection result of the humidity sensor 17, the control device 11 operates the humidification filter vertical movement device 12 to move the humidification filter 3 over the water surface 9 and the motor 6 is operated. By operating, it is possible to provide a function as a device having only an air cleaning function without humidification.

A water level state display 23b to be displayed is also provided.

  As an operation example, when the water level is below the limit water level, only the drought state display 23a is blinked or turned on and the water level state display 23b is turned off to clearly indicate the drought to the user and inform the user that the humidification operation has stopped. When the amount of water is secured, the user can be notified of the remaining amount of water by turning off the drought state display 23a and turning on the water level state display 23b. Here, in the example of the water level display 23b, a mark indicating the remaining water amount in five levels is used here together with a character that expresses that the water level is expressed, and a mark that is represented by a square symbol here. It is displayed. In this example, the white squares are in a state without water, and the black solid squares are in a state with water, and the water amount retention state from the bottom to the third stage among the five stages is shown.

  With the above configuration, the user can arbitrarily switch the operation and stop of the humidifier by the operation stop switch 19. Further, a humidified air cleaning function for simultaneously performing humidification and air cleaning by the mode setting switch 20 and an air cleaning function for performing only air cleaning by moving the humidification filter onto the water surface can be arbitrarily selected. Further, the required air volume can be set by arbitrarily switching the output of the motor with the air volume setting switch 21 in both the humidified air cleaning function and the air cleaning function.
