Description

[Detailed description of the invention] The present invention relates to an air conditioner that is installed on the floor and has both cooling and heating functions. By providing an air intake port on the floor of the air conditioner body and having a structure in which the air sucked in from the air intake port passes through a drain tray, it is possible to completely air condition every corner of the room, and the heat exchange capacity is also increased. The purpose of the present invention is to propose an air conditioner in which a large heat exchanger can be installed in the main body, and the main body itself can be made smaller than conventional ones.

In the conventional air conditioner of this type, as shown in FIG.
3, and the drain tray 30 is only used for collecting and draining liquid, and has a structure that does not allow air to pass through at all, so air is not sucked into every corner of the room, especially near the floor. There is inadequate and unsatisfactory air conditioning. Furthermore, due to the mounting position of the suction port, the heat exchanger is disposed in such a way that it takes up space in the vertical direction, resulting in a problem that the main body itself becomes large.

The present invention has the configuration described in the claims of the utility model registration, that is, an air intake is provided in the floor part of the air conditioner main body, a heat exchanger is disposed above the air intake, and the heat exchanger and A drain tray is disposed between the air intake port and the drain tray for collecting and draining condensed water generated from the heat exchanger, and the drain tray has one end pivotally supported on the shoulder of the drainage channel and the other end supported by the drain tray. an upper drain tray in which a plurality of gutter members attached so as to be movable up and down are arranged side by side so that the opening is located upward;
Below the upper drain tray, a plurality of gutter members are arranged in parallel so that the openings are located upward, and the gutter members are located between at least the edges of each gutter member constituting the upper drain tray. By arranging the drain tray and the drain tray at a predetermined distance in the height direction, complete air conditioning can be achieved in every corner of the room, and the heat exchange capacity for good heat exchange is achieved. To provide an air conditioner in which a large heat exchanger can be installed in the main body, and the main body itself can be made smaller than conventional ones.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated based on the Example shown in drawing.

As shown in FIGS. 1 and 2, an air conditioner main body 1 has an air outlet 2 formed at its upper end, and a filter 3 for removing (adhering) dust is disposed inside and above the main body 1. has been done.

A blower 4 for air circulation is provided below the filter 3, and a heat exchanger 5 for cooling/heating is further provided below the blower 4. A drain tray 6 is provided below the heat exchanger 5 to collect and drain condensed water generated by the heat exchanger. An air intake port 7 for taking indoor air into the main body 1 is provided at the bottom of the lower end of the main body 1, that is, below the drain tray 6. A pre-filter 8 for (adhesion) is attached.

With the above structure, indoor air is taken into the main body from the air intake port 7 on the floor of the main body 1 by the blower 4 in the main body, heat exchanged through the heat exchanger 5, and then passed through the filter 3 to blow the air. Return to the room via exit 2.

FIGS. 3 and 4 show an embodiment of the drain tray 6, in which a gutter member having a cross-sectional shape is arranged in two stages with the opening thereof facing upward and with an appropriate gap l. are arranged, and constitute an upper drain tray and a lower drain tray, respectively. A plurality of gutter members 9 of the upper drain tray and gutter members 9a of the lower drain tray are arranged in parallel at appropriate intervals L ₁ and L ₂ in the width direction, respectively.

Further, the width L of the bottom of the gutter member 9 of the upper drain tray is the interval L ₂ of the gutter member 9a of the lower drain tray.
The bottom of the gutter member 9 of the upper drain tray is at least the same width or wider than that of the gutter member 9 of the lower drain pan.
It is configured to be located on the upper extension line of the interval L ₂ of a. Further, the gutter member 9 of the upper drain tray and the gutter member 9a of the lower drain tray are arranged with a predetermined gap l that allows air to pass through, and the gap L ₂ between the gutter member 9a of the lower drain tray and the gutter member 9a of the upper drain tray A ventilation path 11 through which air passes is formed by the gap ₁ between the gutter member 9 of the saucer and the gutter member 9a of the lower drain tray, and the gap L1 between the gutter member 9 of the upper drain tray.

each gutter member 9 of the upper and lower drain trays;
The end surface of the upper part of 9a is pivotally supported by a drainage channel via a support member, and the end of the lower part thereof is made into an opening 12 for drainage. The opening 12 faces a drainage channel 13 provided in the main body 1, and a drainage pipe 14 projecting outward from the main body 1 is communicated with the drainage channel 13.

With the above configuration, the condensed water generated by the heat exchanger 5 is completely collected in the gutter member 9 of the upper drain tray and the gutter member 9a of the lower drain tray, and the collected condensed water is transferred from the gutter members 9, 9a. The water is discharged to the outside of the main body 1 through the drain pipe 14 through the drain channel 13 . In addition, the air sucked in from the air intake port 7 on the floor of the main body 1 is transferred to the drain tray 6.
The heat exchanger 5 is sent to the heat exchanger 5 through a ventilation passage 11 formed in the air.

The drain tray 6 having such a structure collects and drains liquid and allows air to pass through as described above, and at the same time has sound insulating and sound absorbing properties by arranging the gutter members 9 and 9a as described above. It also has a sufficient effect of muffling the drive noise generated by the blower.

Further, in the present invention, as shown in FIG. 5, the drain tray 6 has a structure in which the gutter member 9 of the upper drain tray is pivotally mounted so as to be able to move up and down.

That is, the lower end of each upper gutter member 9 on the side of the opening 12 is pivotally supported in the drainage channel by a pin 15, and the other end in the main body is provided with a movable end that can be moved in the vertical direction. A drive mechanism 16 is attached for causing the movement. The drive mechanism 16 includes an operating handle 1
7 via a gear 18 and rotates with the operation of the handle 17, and a sliding member 20 fixed to the gutter member and engaged with the rod 19, As the rod 19 rotates, the sliding member 20
, so that the gutter member 9 is configured to move up and down centering on the end of the lower portion.

By making the gutter member of the upper drain tray movable up and down in this way, the gutter member 9 of the lower drain tray can be moved up and down.
The distance l between the drain tray and the drain tray can be adjusted, thereby making it possible to adjust the volume of air passing through the drain tray. This is based on the degree of clogging of the filter 3 and pre-filter 8.
It has the advantage of being able to adjust the amount of air circulating inside.

That is, when the filter 3 and the pre-filter 8 are not clogged at all, the interval l between the upper drain tray and the lower drain tray is made smaller to adjust the rated air volume required by the heat exchanger, and the filter 3 and the pre-filter 8 are By gradually increasing the distance 1 depending on the degree of clogging of the prefilter 8, a predetermined amount of air can always be supplied to the heat exchanger.

The drive mechanism is not limited to the above configuration, and any mechanism that can change the opening angle of the gutter member 9 may be used.

As mentioned above, the air conditioner of the present invention has a two-stage gutter-like drain tray with an opening located above, which is disposed below the heat exchanger disposed inside the air conditioner main body. The condensed water can be completely collected and drained, and the tray has a ventilation path that allows the air sucked in from the air intake port on the floor of the main body to pass through to the heat exchanger side. By forming it on the surface, complete air conditioning can be achieved in every corner of the room and near the floor, and by making the upper drain pan move up and down, the air volume can be adjusted according to the degree of filter clogging. In addition, by making the drain tray have a structure with a ventilation passage as described above, the space inside the main body can be used without wasting it, and therefore a heat exchanger with a large heat exchange capacity that can perform heat exchange well can be created. This type of air conditioner is particularly effective in that it can be installed inside the main body and the main body itself can be made smaller than conventional ones.
