Abstract

PURPOSE:To provide a thin cooling device which can prevent water from scattering, by inclining the upper section of an evaporator in the direction of air stream so that a water receiving section has a double structure, and by communicating a space between the upper and lower water receiving sections with a space between a stabilizer and the lower water receiving section. CONSTITUTION:Air sucked from a suction port 10 is cooled down by an evaporator 1 and is then discharged from a discharge port 11. At this time, a part of condensate produced in the evaporator 1 flows along the evaporator 1 and is then absorbed by a partition plate 6, and the remainder part of the condensate is dripped by its deed weight due to an effect of air flow, directly onto, and is absorbed by the partition plate 6 since the upper section of the evaporator 1 is inclined in the direction of air flow. When the partition plate 6 has been saturated, the condensate is dripped into a lower casing 3, and is discharged outboard through a drain port 9. With this arrangement in which the condensate is pooled only in a space 8 between the lower casing 3 and the partition plate 6, water leakage and scattering may be prevented even during acceleration or deceleration of an automobile or in such a condition that the automobile falls into any of various inclined conditions. Further, the use of a cross fan enables the cooling device to be thinner.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ceiling-mounted cooling device for automobiles.

2. Description of the Related Art A conventional ceiling-mounted cooling device for automobiles is disclosed, for example, in Japanese Utility Model Publication No. 62-5927.

As shown in FIGS. 3 and 4, this device consists of a case 5 suspended from the ceiling 7 of an automobile 1, a motor 8 attached to the case 5 with its rotating shaft 9 facing downward, and It has a centrifugal fan 4 attached to the rotating shaft 9 and arranged inside the case 5, and an air suction port 10 formed in the case 5 corresponding to the central suction opening 4A of the centrifugal 7-an 4. The suction port 10 is formed on the upper surface of the case 5 to face the ceiling 7, the central suction opening 4A of the centrifugal fan 4 faces upward corresponding to the air suction port 10, and the motor 8 is connected to the air suction port 10. 10, at least a part of which in the axial direction is located within the central suction opening 4A of the centrifugal fan 4, and the case 6 is formed to cover the lower part of the centrifugal fan 4, so that the drain water wheel is Prevents falling indoors.

However, the problem that the invention aims to solve is that ceiling-mounted cooling devices for automobiles are forced to be larger and thicker in the height direction, and have not been adopted in general vehicles. This is the current situation.

Therefore, in order to eliminate the above-mentioned drawbacks, the present invention aims to reduce the thickness of the fan by using a cross flow fan, and also to reduce the size and appropriately perform water treatment by considering the arrangement of heat exchangers, etc. It is.

Means for Solving the Problems In order to achieve the above object, the present invention has a cross-flow fan, the upper part of the evaporator is inclined in the direction of wind flow, and the water receiving part has a double structure, so that the upper water The receiving part is made of water-absorbing material, and a stabilizer is installed in the lower water receiving part.
The space created by the upper water receiver and the lower water receiver is connected to the space created by the stabilizer and the lower water receiver.

For production The effect of this technical means is as follows.

A ceiling-mounted cooling unit for an automobile is formed using a cross-flow fan.1. By pouring water into the stabilizer part, which is the boundary between air intake and discharge, and separating the condensate water receiver part with a water-absorbing material while floating it above the condensate water receiver part, we have created a thin unit. This has the effect of preventing condensed water from scattering and falling.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes an evaporator which is fitted and held by an upper case 2 and a lower case 3. Further, the evaporator 1 is constructed with its upper part tilted in the direction of the wind flow. It is composed of a le floor part C that generates wind, an upper case 2, a cross flow fan 4, a fan morph 12, and a stabilizer 5, and the stabilizer 5 is
It is provided at the lower part of the cross flow fan 4 and in the descending section 3. Reference numeral 6 denotes a partition plate which has the function of absorbing condensed water generated by the evaporator 1 and discharging water to the lower case 3 when the water absorption capacity is saturated. Reference numeral 7 denotes a discharge port, which serves to discharge water discharged into the lower loaf 3 into a space 8 created between the stabilizer 5 and the lower case 3. 9 is the drain port and space 8
It has the function of discharging condensed water sent to outside the vehicle. Further, 1o is a suction port, and 11 is a discharge port, which respectively take in and exhaust air.

With the above configuration, the air sucked through the suction port 10 is cooled by the evaporator 1 and discharged from the discharge port 11. At this time, the condensed water generated in the evaporator 1 is partially absorbed by the flow partition plate 6 along the evaporator 1 because the evaporator 1 is configured with its top tilted in the direction of the wind flow. The remainder is directly dripped onto the partition plate 6 and absorbed by the weight of the condensed water due to the effect of wind flow. When the partition plate 1 reaches the saturated state, the condensed water flows to the lower case 3.
and is discharged from the drain port 9 to the outside of the vehicle. Therefore,
Condensed water collects only in the lower case 3, partition plate 6, and space 8, and is highly effective in preventing water leakage and splashing even when mounted on a car and under acceleration, deceleration, and various inclination situations. be.

In addition, the drain port 9 is provided in the space created between the lower case 3 and the stabilizer 5, and has a discharge lower, so a volume for condensed water to accumulate can be secured, and the There is no need to worry about water leakage when moving condensed water, and as a result, the overall thickness of the unit can be reduced.

Effect of the invention.

In the present invention, the upper part of the evaporator is tilted in the direction of the wind flow, the water receiver has a double structure, the upper water receiver is made of a water-absorbing material, and the lower water receiver is provided with a stabilizer. This is a ceiling-mounted cooling unit for automobiles that is characterized by connecting the space created by the upper water receiver and the lower water receiver with the space created by the stabilizer and the lower water receiver. This has the effect of preventing water leakage and water scattering caused by tilting, and also being thin.
