Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a ceiling-suspended type air conditioning unit that is hung from the ceiling or a ceiling-embedded type air conditioning unit that is embedded in the ceiling space.

(b) Conventional technology For example, the ceiling-mounted air conditioning unit was developed by Jikosho.
As shown in Publication No. 47-21554, drain water generated during cooling operation is collected in a drain container and discharged outdoors through drain piping in the ceiling space. However, if the unit body is not installed horizontally, After installation, drain water will accumulate in the
It was necessary to use a spirit level to check whether the unit body was level.

In addition, in order to create a drain slope in the drain pipe, the drain container must be installed at a high position within the unit body, which increases the height of the unit body. Attempts have been made to incorporate a built-in drain pump.

(c) Problems that the invention aims to solve: It was a tedious task to check with a spirit level whether the unit body was level. In addition, after installing the unit, it is necessary to test run the drain pump by pouring water into the drain container to check whether the drain pump is working properly. Since water is poured into the drain container, there are problems such as water splashing from the drain container when pouring water, causing the drain pump motor to get wet and the inside of the unit getting wet, and problems such as overflowing from the drain container due to too much water being poured. It was hot.

The present invention provides an air conditioning unit that solves all of these problems at once.

(d) Means to solve the problem This proposal consists of a drain pump that drains the drain water in the drain container, and a drain pump (L) that communicates with the bottom of the drain container and supplies water to the drain container for trial operation of the drain pump. The water injection pipe is made of a transparent material.

(E) Function When injecting water into the drain container for a test run of the drain pump, water is gently guided from the water injection pipe to the bottom of the drain container via the water passage pipe. You can check how much water has been poured into the drain container by checking the level of the water injected on the transparent water pipe, and by visually observing the slope of this water level, you can confirm that the unit is installed horizontally. can be done.

(f) Example Figure 1 is a vertical cross-sectional view showing the installation state of a ceiling-embedded air conditioning unit, and Figure 2 is a perspective view of the ceiling-embedded air conditioning unit, with heat insulating material 1 affixed to the inner wall. Unit body 2 made of sheet metal and suction grill 3 in the center
The exterior casing of the ceiling-embedded air conditioning unit is constituted by a ventilation decorative panel 9 provided with air outlets 5, 6, 7, and 8 with airflow direction changing blades 4 on the four sides of the outer periphery.

10 is from the suction grill 3 to the air filter 11
A nozzle port 13 is connected to a support leg 15 on a nozzle plate 14 for sucking and guiding indoor air into a turbo fan 12 through a nozzle port 13.
16 is an annular drain container disposed along the outer periphery of the nozzle opening 10; 17 is sandwiched between the drain container 16 and the spacer 18 and is disposed so as to surround the turbo fan 12; The annular evaporator 19 is a hanging bolt for pushing the unit body 2 into the ceiling space 22 through the ceiling hole 21 of the ceiling plate 20 and suspending and fixing it to the ceiling beam 23.

Further, reference numeral 24 is located at a corner protruding portion of the drain container 16, and the drain water in this drain container is scooped up by the drive of a motor 25 and drained into the drain pipe 26.
As shown in FIG.
A substantially L-shaped transparent water injection pipe is detachably attached to a water pipe 29 that communicates with the bottom of the water injection pipe 6 , and 30 is a water level line marked on the funnel part 31 of this water injection pipe 28 .

After the unit main body 2 is suspended in the ceiling space 22 with the hanging bolts 19, 19, and the outdoor unit containing the compressor and condenser is connected to the refrigerant piping and electrical control lines, the unit is constructed as described above. , water pipe 2
The water injection pipe 28 is inserted into the water injection port 32, water is poured into the drain container 16, and a cooling test run and a test run of the drain pump 24 are performed. During this water injection, since the water injection pipe 28 is transparent, the water level 33 in the drain container 16 can be confirmed from the liquid level 34 of the water injection pipe 28.
Water never overflows.

Also, visually check whether the water injection surface 34 is tilted, and if it is, adjust the hanging bolts 19, 19 to correct the inclination of the unit body 2 so that the water injection surface 34 is horizontal. The unit main body 2 is installed horizontally in the left and right direction as well as in the depth direction.

Such horizontal positioning work can be easily performed by using the water level line 30 as a guide for setting the water injection amount to an appropriate amount and checking whether this water level line and the water injection liquid level 34 match over the entire circumference. , and by providing this water level line 30 in the funnel portion 31 having a large diameter, it is possible to confirm the coincidence of the water level line 30 and the water injection surface 34 with higher accuracy. In addition, as shown in FIG. 1 by dashed lines, the water injection pipes 28 are installed symmetrically,
By checking whether the water injection level 34 matches the water level lines 30, 30 of the water injection pipes 28, 28, the accuracy of horizontal positioning can be further improved.

Also, if the water injection pipe 28 is removed from the water pipe 29, the drain water in the drain container 16 will be discharged, so cleaning the drain container 16, repairing the drain pump 24, etc.
Easy to replace.

(g) Effects of the invention According to the invention, water is injected into the bottom of the drain container through the water injection pipe, so there is no risk of water splashing and getting the drain pump motor or unit body wet, and the water injection pipe is transparent. Since the water injection level can be visually observed, it is possible to prevent water from overflowing from the drain container due to excessive water injection, and it is also possible to easily check the horizontal positioning of the unit main body from this water injection liquid level.
