Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to drain water treatment for an integrated air conditioner.

Prior Art A conventional integrated air conditioner was constructed as shown in FIG.

That is, in the same figure, the integrated air conditioner 1
01, the main body is constituted by a substrate 102, a bulkhead 103 that divides indoor and outdoor areas, an outer box 104, etc. on the substrate 102. Further, on the indoor side, an evaporator 105 and a water tray 106 constituting a well-known refrigeration cycle are provided on the substrate 102, and a Sirotskov fan 108 that sends air to the evaporator 105 is attached to one end of a fan motor 107. . On the outdoor side, a condenser 109 is provided on the back side, and a condenser 10 is provided at one end of the fan motor 107.
Propeller fan 1 with ring 110 that sends air to 9
11 is installed. 112 is a compressor, and by operating this compressor 112, the refrigeration cycle functions, the evaporator 105 cools the indoor air, and drain water flows down onto the water tray 106.
Drain water is led to the lower part of the ring 110 of the propeller fan 111 through the drain water outlet 113 of the water receiver 106 at the bulkhead 103 position and the drain water passage 114 of the base plate 102.
10 and sent to the condenser 109, it adheres to the condenser 109 and is evaporated.

Problems to be Solved by the Invention In the above structure, cold drain water flows into the water tray 1.
When flowing out from the drain water outlet 113 of 06 to the drain water passage 114 of the substrate 102, the substrate 102 is cooled and dew condenses on the lower surface of the drain water passage 114 of the substrate 102.

In particular, if the direction of rotation of the propeller fan 111 is such that wind pressure is applied to the drain water channel 114 (rotation to the left when viewed from the back), the water tray 106
Since the drain water flowing out from the drain water outlet 113 into the drain water flow path 114 is pushed back by wind pressure, the very cold drain water that has just flowed out from the drain water outlet 113 does not flow and stagnates, causing the substrate 102 to be locally strengthened. It cools down and causes significant condensation.

This condensation not only dampens the windows and walls on which the integrated air conditioner is installed, damaging their appearance, but also causes corrosion if the windows and walls are made of wood or the like.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a drain water channel having an inclination in the substrate so as to extend from the drain water outlet of the water tray to the lower part on the opposite side to the rotational direction of the propeller fan. A groove and a small opening are provided on an extension of the groove in the lower part of the air guide.

Effects The effects of this technical means are as follows. In other words, the groove that slopes from the drain water outlet of the water pan to the lower part on the opposite side of the rotation direction of the propeller fan and the opening on the extension line of the groove in the lower part of the air guide prevent the drain water from staying in a fixed place. Because it flows smoothly and is guided to the bottom of the propeller fan, the cold drain water cools the circuit board and does not cause condensation, and there is no need to attach insulation material to the bottom of the circuit board. There will be no staining or damage to the appearance of the wall.

Embodiment Hereinafter, an embodiment of the present invention will be described in FIGS. 1 to 3.
The explanation will be explained with reference to the figure.

In the figure, reference numeral 1 denotes an integrated air conditioner main body, which is composed of a front grill 2, an outer box 3, and an internal unit 4 housed inside the outer box 3 so as to be drawable. The indoor unit 4 is provided with a bulkhead 6 on a substrate 5, which separates an outdoor side and an indoor side.
A U-shaped condenser 7 is mounted on the outdoor side facing the bulkhead 6, and an inclined groove 8 is provided from the vicinity of the bulkhead 6 mounting portion of the substrate 5 to the vicinity of the condenser 7. Between the bulkhead 6 and the condenser 7 are a propeller fan 10 provided with a slinger ring 9, a fan motor 11 with the propeller fan 10 attached to one end of the shaft, a fan motor mounting plate 12 for fixing the fan motor 11 to the bulkhead 6, and a propeller. An air guider 13 is provided to guide the wind from the fan 10. A small opening 14 is provided in the lower part of the air guider 13 at a position on the extension of the groove provided in the substrate 5. 15 is a compressor.

Next, the indoor side will be explained. On the indoor side, an L-shaped evaporator 16 is provided opposite the front grill 2, and between this evaporator 16 and the bulkhead 6,
A Sirotskov fan 17 is attached to one end of the shaft of the fan motor 11, and a casing 18 is provided to form a flow path for guiding the wind of the Sirotskov fan 17. A water tray 19 is provided below the evaporator 16 for collecting cold drain water generated in the evaporator 16 and guiding it to the outdoor side.

In the above configuration, the cold drain water generated in the evaporator 16 passes through the water receiving tray 19, the drain water outlet 20 under the bulkhead 6, and flows out to the outdoor side of the substrate 5. The cold drain water that flows out flows along the inclined groove 8 provided in the base plate 5, passes through the opening 14 in the lower part of the air guide 13, and flows below the propeller fan 10. At this time, air guider 1
The opening 14 at the bottom of 3 is on the opposite side to the rotation direction of the propeller fan 10, and due to the characteristic that wind pressure is applied in the rotation direction of the propeller fan 10, the cold drain water is forced away from the opening 14 in the rotation direction, and from outside to inside (propeller fan 10)
below). Therefore, the flow rate of drain water flowing along the groove 8 is accelerated, and the water receiving tray 19
The cold drain water that has exited the drain water flows smoothly below the propeller fan 10 without stagnation anywhere along the way, and is warmed by the outside temperature and the heat released from the condenser 7 during the movement. Also, below the propeller fan 10,
Since the wind pressure changes rapidly, the drain water circulates inside the U-shaped condenser 7, is scraped up by the slinger ring 9 of the propeller fan 10, is blown to the condenser 7, and evaporates.

Effects of the Invention As is clear from the above-mentioned embodiments, the present invention allows drain water to be smoothly guided from the drain water outlet of the water tray to the lower part of the propeller fan without remaining in a fixed location, so that the cold drain water touches the substrate. It cools locally and does not cause condensation. For this reason,
As a measure against condensation, attaching insulation material to the bottom of the board eliminates the need to attach separate parts, and the appearance of windows and walls where the integrated air conditioner is installed will not be contaminated by condensed water. It has various effects such as.
