Description

[Detailed Description of the Invention] This invention relates to a novel ceiling-mounted air conditioner incorporating a humidifier.

Nowadays, ceiling-mounted air conditioners are often installed as air conditioners in various stores, etc., instead of conventional indoor floor-standing air conditioners.

This ceiling-embedded type air conditioner has the advantage of not reducing the sales floor area of a store because it does not protrude into the indoor space, and also has the advantage of being easily harmonious with the diversifying interior designs and product display aspects.

In general, a ceiling-mounted air conditioner has a structure in which a panel having both an air outlet and an air inlet is attached to a ceiling surface, and an in-ceiling casing is attached to the panel in an airtight manner. A blower, a heat exchanger, an air passage, etc. are incorporated inside the casing, and although the compressor unit is generally installed outdoors, it may also be housed inside the casing.

In any case, the equipment inside the casing is compactly stored, and in the so-called cassette type, in the event of a breakdown or repair, the equipment can be easily removed and replaced by opening the panel on the ceiling. It is a special feature.

By the way, when this ceiling-embedded air conditioner is operated for heating, humidification must be performed by some method in order to maintain a comfortable indoor air environment. Particularly when outside air is introduced into an air conditioner, the indoor air becomes even more dry during heating, and humidification becomes an essential condition.

This invention was made with the aim of providing comfortable air conditioning (cooling and heating) by effective humidification without impairing the above-mentioned features of the ceiling-mounted air conditioner.

For this reason, in the present invention, a panel installed on the ceiling surface is equipped with an air outlet and an air intake port, an in-ceiling casing that houses a blower, a heat exchanger, an airflow passage, etc. is airtightly installed on the panel, and the panel is attached to the ceiling surface. This is a ceiling-mounted air conditioner that allows the ceiling casing to be taken out together with the panel by removing it from the ceiling, and the humidifier body is attached to the outside of the ceiling casing, and air is introduced into the humidifier body. The pipe and the mist guide pipe are connected, and the wind introduction pipe and the mist guide pipe are passed through the casing and opened into the casing, and the mist distribution pipe in the ceiling casing of the mist guide pipe is connected to the inside of the air conditioner. It is characterized by being arranged close to the airflow inflow side of the heat exchanger so that the mist released from the plurality of blow-off holes formed in the mist distribution pipe immediately flows into the heat exchanger. .

The invention will now be explained in detail with reference to preferred embodiments shown in the drawings.

In the figure, reference numeral 1 denotes a panel that is removably attached to a ceiling surface (not shown) by a known attachment means, and this panel 1 is provided with an air outlet 2 and an air inlet 3. 4 is an in-ceiling casing airtightly attached to the panel 1, and a blower 5, a heat exchanger 6, and an airflow passage 7 are housed in the in-ceiling casing 4,
Similar to a known air conditioner, air is sucked in from the suction port 3 by the operation of the blower 5, this air is heat exchanged in the heat exchanger 6, 6 section, and is blown out from the air outlet 2 through the air flow passage 7. .

In the figure, reference numeral 8 denotes the main body of the ultrasonic humidifier, which is removably mounted and fixed on a mounting base 9 fixed to the outside of the side wall 4' of the in-ceiling casing 4. A wind introduction pipe 10 and a mist guide pipe 11 are connected to this ultrasonic humidifier main body 8, and the wind introduction pipe 10 and mist guide pipe 11 are passed through the side wall 4' of the in-ceiling casing 4. The inside of the casing 4 is opened.

These wind introduction pipes 10 are mainly connected to the casing 4
It is composed of a straight pipe 12 housed inside the casing 4 and a flexible pipe 13 located outside the casing 4. Similarly, the mist guide pipe 11 is mainly a straight pipe housed within the casing 4 and is composed of a mist distribution pipe 14 having a large number of blowing holes 15, and a flexible pipe 16 located outside the casing 4. There is.

In the present invention, as shown in FIGS. 2 and 5, the mist distribution pipes 14 and 14 are arranged close to the heat exchangers 6 and
The mist blown out from the blow-off hole 15 is opened toward the heat exchanger 6 so that it can immediately flow into the heat exchanger 6 and be completely vaporized.

In addition, in the illustrated embodiment, the wind introduction pipe 10 and the mist guide pipe 1 are
1 have removable connecting portions 17 and 18 at outer positions of the casing 4, respectively. In the illustrated embodiment, as shown in FIG.
The proximal ends of the flexible tubes 13 and 16 are made to protrude outward from the side wall 4' of the casing 4, and the protruding portions and the tips of the flexible tubes 13 and 16 are fitted together and fixed by hose bands 19 and 20. By disconnecting the connection parts 17 and 18, the humidifier main body 8 can be easily removed, and it can be easily taken out from the ceiling for maintenance and inspection, which is effective. be.

In the present invention, which has the above configuration, a panel installed on the ceiling is equipped with an air outlet and an air intake, an in-ceiling casing containing a blower, a heat exchanger, etc. is attached to the panel, and the panel is removed from the ceiling. This is a ceiling-embedded air conditioner that allows the ceiling casing to be taken out to the outside together with the panel, and the mist distribution pipe inside the ceiling casing of the mist guide pipe is used for heat exchange inside the air conditioner. It is characterized in that it is arranged close to the airflow inflow side of the device so that the mist released from the plurality of blow-off holes formed in the mist distribution pipe immediately flows into the heat exchanger. The mist released from the outlet of the mist distribution pipe is carried by the airflow and immediately enters the heat exchanger, where it is heated and completely evaporated, providing effective humidification and comfortable air conditioning. Can be done. As mentioned above, the fog completely evaporates and vaporizes.
This has the advantage of improving humidification efficiency by eliminating the risk of condensation condensing on the outlet of the air conditioner or condensing on the inner surface of the casing of the air conditioner, impairing insulation or causing metal corrosion. Moreover, it has the advantage of not detracting from the above-mentioned characteristics originally possessed by the ceiling-mounted air conditioner.
