Abstract

PURPOSE:To humidity by evaporating in a room utilizing the air speed of a contained fan, by a method wherein a fiber net having good qualities of water absorbing and sucking is provided at the front of a heat exchanger in the room, and the under part of the fiber net is immersed in a water plate containing a float switch which is added to a dew receiving plate. CONSTITUTION:By providing a humidifying filter 8 to which small protrusions are added on the periphery surface of fiber yarn 13 to make effective the water absorption and raising between a filter 4 and the heat exchanger 1, and a water receiving part for humidifying is provided additionally to the dew receiving plate 7 at the lower end of the humidifying filter 8, the humidifying filter 8 is humidifyed and moisture is evaporated by the ventilation of the contained fan 2 and is blown out in the room and the humidifying is performed. As the means to supply water to the humidifying filter which is adopted in this case, a water tank 12 is provided facing downward at the outside of in-door devices, and water is supplied to the water receiving part for moitening of the water receiving plate 7 by an electro-magnetic pump 11. Still more, to prevent overflow of the water receiving part for humidifying, the float switch is provided at the end of the water receiving part, and water level is maintained constant by coupling with the electro-magnetic pump 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to humidification for a heat pump type air conditioner, and particularly to evaporative humidification suitable for adjusting indoor humidity during heating.

[Background of the Invention] Conventionally, Japanese Utility Model Application Publication No. 51-50845 and Japanese Utility Model Application No. 51-50845
As described in Publication No. 50846, etc., the ultrasonic humidification attached to a heat pump type air conditioner uses ultrasonic cavity blowing, and is convenient for rapid humidification when fine moisture is sprayed into a room by ventilation. It is. However, on the other hand, because the airflow is rapid, if the airflow rate is insufficient, there is a risk that the floor near the air conditioner will get wet, so it is necessary to pay attention to the airflow rate for local spraying.

[Purpose of the invention]

An object of the present invention is to provide air conditioning during heating by an air conditioner by adding an evaporative humidification function using a fan built into the indoor unit of the heat pump air conditioner.

[Summary of the invention]

That is, in order to maintain comfortable indoor humidity during heating, the present invention provides a fiber net with good water absorption and wicking performance on the front of the indoor unit heat exchanger, and an additional L7'C float switch built-in water filter is installed in the dew pan at the bottom of the heat exchanger. The lower part of the fiber net is immersed in a saucer, and the water is vaporized and humidified indoors by utilizing the built-in wind speed of 77 mph.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The indoor unit has a heating function in which the air that passes through the grill 3 and filter 4 through the built-in 7A/2 indoor unit is heated by the heat exchanger 1 and blown into the room via the wind direction plate 6 (Figure 1). , a humidifying filter 8 is placed between the filter 4 and the heat exchanger 10 by adding fine protrusions 14 to the outer peripheral surface of the thin fiber thread 16 that effectively balances water absorption and water pumping. By additionally providing a humidifying water receiving part to the dew receiving tray 7 at the lower end, the humidifying filter 8 is moistened, and the moisture is vaporized by the ventilation of the built-in fan 2 and blown into the room to be humidified. In this case, as a means for supplying moisture to the humidifying filter 8 adopted in the present invention, as shown in FIG. Supply water to the humidification water receiver. In order to prevent the humidifying water receiver from overflowing, a float switch was placed at the end of the water receiver and was linked to the electromagnetic pump 11 to keep the water level in the water receiver constant.

According to this embodiment of evaporative humidification with a suction mechanism using water supply, it is possible to create an environment that gently humidifies the entire room, and by selecting a fiber mesh MEC^, the fan air volume and heating capacity can be maintained. becomes possible.

〔Effect of the invention〕

According to the present invention, humidification is added at the same time as indoor heating.
With the introduction of air pump air conditioners, the indoor environment, which is forced to drop in relative humidity due to natural ventilation due to the dry outdoor conditions in winter and the rise in room temperature, can be reduced to a relative humidity of around 50 degrees (6 to 10 degrees), which is considered to be a comfortable humidity. (tatami)) has the effect of maintaining it.

Furthermore, according to the moisture supply using the wicking fiber network, which is the basis of the present invention, the amount of vaporization increases when indoor humidification starts, and when the humidity is stable, the amount of vaporization decreases, resulting in the effect of naturally controlling moisture supply. Economical simplification can be achieved by supplying water to these fiber networks in the evening, which allows for long-term water supply during heating. Moreover, by using an electromagnetic pump, a constant amount of water can always be obtained regardless of the pumping height, and since the amount of water is almost the same as the amount of vaporized water, there is an effect of preventing water leakage from the water receiving portion.
