Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention includes an air cooling mechanism and a water supply mechanism, such as a water-cooling type air conditioner for a toilet. The water supply mechanism includes a water supply pump arranged in a water tank and a water supply mechanism. The present invention relates to a water-cooled air conditioner having a water supply pipe that guides cooling water drawn by a pump to an air cooling mechanism.
The present invention also relates to a water supply device suitable for such a water-cooled air conditioner.

2. Description of the Related Art As a conventional water-cooling type air conditioner for a toilet, an air conditioner body is installed above a cistern, and the water drawn up from the cistern is scattered to the condenser to radiate the heat from the condenser. An air conditioner that drains the used water into a toilet has been proposed (for example, JP-A-58-26941).
Issue). However, in this conventional configuration, since the air conditioner and the tank are integrally configured, the structure becomes extremely complicated in the case of retrofitting, and a wide variety of flush tanks (toilet bowls) Difficult to adapt to. As another conventional water-cooled air conditioner for toilets,
A cooling water storage tank that cools the condenser is integrally attached to the main body of the air conditioner, and tap water is pumped out from the spare water intake of the cistern, and a water supply facility for supplying cooling water to this cooling water storage tank is installed. It is proposed to provide the device (for example, Japanese Utility Model Laid-Open No. 4-103525). However, in this conventional configuration, since it is necessary to install a large water supply facility on the side of the cistern, the installation location of the main body of the air conditioner is at a low position, so the air outlet is also at a low position and a feeling of cold air is felt. Hard to get. Further, if the main body of the air conditioner is installed at a high position, it becomes difficult to install it on the side of the cistern, and it is not possible to secure an appropriate installation place in a narrow toilet. Therefore, diversion water from the toilet stored in the flush tank is diverted to cool the water-cooled condenser of the water-cooled air conditioner,
It is desired that the cooling water is returned to the washing tank again so that a separate cooling water storage tank is not provided. In addition, it is desirable that the installation can be performed without the need for installation work by a specialist, and that even flush toilets of different types can be installed. Therefore, it is conceivable to supply the cooling water to the air cooling mechanism by introducing the water supply pump into the flush tank and guiding the cooling water pumped up by the water supply pump to the air cooling mechanism by the water supply pipe. According to this configuration, the lid on the upper part of the flush tank can be opened and the water supply pump can be turned on.
Since it does not require installation work by a specialist or a separate tank for storing cooling water, it can be easily installed even in a narrow space or with different flush toilet types.

[0003]

However, when the method of introducing the water supply pump into the flush tank is adopted, it is necessary that no air remains in the water supply pump. That is,
As the water supply pump used in such a case, a water supply pump which is usually called a centrifugal type is used so that it can operate normally even if foreign matter is sucked in. However, this type of feed pump is different from a positive displacement pump when air remains inside,
The "air bite" phenomenon occurs, the "starts from" state, and the water cannot be pumped up by the water supply pump. Therefore, when the circulation pump is lifted above the water surface during initial installation, relocation, or repair, an "air trapping" phenomenon may occur. In addition, since the water level in the toilet flush tank drops during use, if the water supply pump is caught somewhere and the water supply pump rises, an "air trapping" phenomenon may occur when the water level in the tank drops. There is a nature. As described above, when the operation is started due to the air trapping phenomenon, the condenser is not cooled, and the air conditioner does not function normally.

Therefore, an object of the present invention is to provide a water-cooled air conditioner capable of preventing the circulation pump from operating. Another object of the present invention is to provide a water supply device suitable for such a water-cooled air conditioner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A water-cooled air conditioner according to an embodiment of the present invention will be described below. (Embodiment 1) FIG. 1 is a sectional view showing the construction of a water-cooled air conditioner according to an embodiment of the present invention.

The water-cooled air conditioner 1 is a floor-standing type, and a compressor 11, a water-cooled condenser 12, an evaporator 14, and a blower 16 are arranged in order from the bottom. In addition, the water-cooled air conditioner 1 is configured to blow out the air that has been sucked through the evaporator 14 by the blower 16. The water-cooled air conditioner 1 uses stored water (toilet flushing water) 20 in a flush tank (water tank) 21 of a flush toilet as cooling water for a water-cooled condenser 12. The water supply mechanism for using the stored water (toilet flush water) 20 in the flush tank (water tank) 21 of the flush toilet is a water supply pump 22 arranged in the flush tank 21 and cooling pumped by the water supply pump 22. The water supply pipe 23 for guiding water to the water-cooled condenser 12 and the cooling water guided to the water-cooled condenser 12 for the water tank 2
Drainage pipe 24 for returning to 1. Wash tank 21
The toilet flushing water 20 inside is sucked in by a water supply pump 22, and is led to a water-cooled condenser 12 which is, for example, a double pipe heat exchanger, via a water supply pipe 23 extending from the inside of the flush tank 21 to the outside. The water-cooled condenser 12 is cooled. Then, the toilet flushing water 20 guided to the water-cooled condenser 12 is returned to the flush tank 21 again via the drain pipe 24.

FIG. 2 is a sectional view of the essential parts of a water supply device for a water-cooled air conditioner according to an embodiment of the present invention. FIG. 3 is a cross-sectional view showing the structure of the water supply pump of this embodiment, and FIG.
FIG. 4 is a cross-sectional view showing a fitting state of a discharge port and a water supply pipe at a water supply pump connection portion shown in FIG. 3. That is, FIG. 4 corresponds to FIG.
The sectional view by the AA line of is shown. As shown in FIG. 2, in the present embodiment, the water supply pump 22 and the water-cooled condenser 12 placed in the flush tank 21 are arranged in a substantially inverted U shape by being bent from the inside of the flush tank 21 to the outside. It is connected via a water supply pipe 23 provided. Water supply pump 22 shown in the figure
Is a centrifugal pump, and is connected to a motor 31, a centrifugal vane 32 rotated by the motor 31, a vane guide 33 that fits with the centrifugal vane 32 to form a water supply function section, and a water supply pipe 23. A motor case 34 having a discharge port 34a for supplying water to the pump 22, and an inner motor case 3 for holding the motor 31 together with the motor case 34.
5, a suction port 36 for sucking in water, a filter 37 provided in the suction port 36, and a motor electric wire 38 for supplying power to the motor 31. In addition, the water supply pump 22,
The spacer 41 is inserted into the fitting portion between the discharge port 34a of the water supply pump 22 and the water supply pipe 23 so that the space inside the water supply pump 22 or the water supply pipe 23 serves as a passage or a gap through which air can be taken in and out. Pores 42 are provided.

The operation of the vent hole 42 will be described with reference to the drawings. When the toilet is used, the toilet flush water 20 in the flush tank 21 decreases, and the water surface drops from the high water level surface 51 shown by the two-dot chain line to the low water level surface 52 shown by the solid line. Vent hole 4 at this time
Air enters from 2 and the inside of the water supply pump 22 and the water supply pipe 23
Of the water, the water in the pipe on the pump side does not escape through the vent hole 42 and the bottom of the water supply pump 22. On the other hand, water is stored inside the water-cooled condenser 12 side pipe of the water supply pipe 23 and inside the water-cooled condenser 23 side pipe of the drain pipe 24. In a normal state, even if the water level drops to the low water level surface 52, the water supply pump 22
Since the water supply function part of is full of water, it will not be in operation. However, if the water supply pump 22 is lifted above the water surface during repair, or if the water supply pump 22 is lifted for some reason, the water supply pump 2
When 2 is newly installed, the air remains inside the water supply pump 22, particularly in the water supply function part formed by the centrifugal vane 32 and the vane guide 33. In such a state, the air in the water supply pump 22 escapes from the ventilation hole 42, and the water supply pump 22
Inside, especially the water supply function part of the water supply pump 22 is filled with water. That is, since the ventilation hole 42 fills the water supply function part of the water supply pump 22 with water, the water supply pump 22 operates normally without operating from the bottom. According to the present embodiment, since the water supply function part formed by the centrifugal vane 32 and the vane guide 33 is filled with water by the action of the vent hole 42, the operation of the water supply pump 22 can be prevented.

Here, the dimensions of the vent holes will be described. If the size (that is, the opening area) of the vent hole 42 is extremely large, leakage from the vent hole 42 causes the water-cooled condenser 12 to leak.
Therefore, the pump head that can supply water cannot be obtained and the original water supply function of the pump is impaired. Therefore, the vent hole 4
In the size of 2, the toilet flush water 20 (the air inside the water supply pipe 23 including the toilet) can be sent to the water-cooled condenser 12 beyond the height of the flush tank 21 even if there is some leakage from the ventilation hole 42. It is necessary to secure a predetermined pump head. In the study, the upper limit dimension of the vent hole 42 is preferably 3.5 mm or less in diameter, that is, 10 mm 2 or less in area. Diameter 3.5 mm or less, area 10
It is possible to secure a flow rate of 85% below a square millimeter. The diameter exceeds 3.5 mm and the area is 10 mm.
If it exceeds sq. Mm, the amount of leakage increases sharply, so the accuracy of the air holes 42 must be made severe. On the other hand, when the size of the vent hole is extremely small, it takes a long time for the air in the water supply pump to escape, and during that time, the operation of the water supply pump may occur, so the air may be exhausted within a predetermined time. Dimensions are desired. For example, in consideration of the time required for the water surface to rise after using the toilet (about 60 to 120 seconds), the lower limit dimension is preferably an area of 0.5 square millimeters (equivalent to a diameter of 0.8 millimeters) or more. However, the operation can be prevented from occurring if the vent hole is of a size that allows air to escape. In addition, the spacer 41 is inserted into the water supply pump connection portion shown in the present embodiment, and the ventilation hole 42 is formed.
With the configuration in which is provided, for example, a commercially available pump used for supplying and draining washing water can be used, and, for example, pump repairability can be improved.

According to the present embodiment, even if air is present inside the pump, if the water supply pump 22 is immersed in water, the air inside the water supply pump 22 will escape from the ventilation holes 42, and water will enter the water supply function section of the water supply pump 22. When filled, the water supply pump 22 operates normally and the operating state of the water supply pump can be prevented. Although the embodiment shown in FIG. 5 (a) is provided with one convex portion 34b,

Is a structure for forming. According to the present embodiment, even if air is present inside the pump, if the water supply pump 22 is immersed in water, the air inside the water supply pump 22 will escape from the ventilation holes 42 and the water supply pump 22 will be filled with water. . Therefore, the water supply function part of the water supply pump 22 is filled with water, and the water supply pump 22 operates normally. That is, of the water supply pump 22,

Since the pump can be used, it has an effect that the repairability of the pump is good. In the embodiment shown in FIG. 6B, one recess 23c is provided, but a plurality of recesses 23c may be provided.

(Embodiment 6) FIG. 7 is a sectional view showing the essential parts of a water supply device for a water-cooled air conditioner according to still another embodiment of the present invention. The water supply device of the water-cooled air conditioner of the present embodiment has substantially the same configuration as that of the embodiment shown in FIG. 2, and different configurations and parts will be described below. Is omitted. The present embodiment has a configuration in which a ventilation hole 42 is provided in a portion of the water supply pipe 23 corresponding to a portion other than the connection portion of the water supply pump 22. That is, the vent hole 42 of the present embodiment is provided in the water supply pipe 23 between the lower position of the high water level surface 51 of the flush tank 21 and the upper position of the connection portion of the water supply pump 22. Also in this embodiment, the operation of the water supply pump 22 can be prevented by the action of the ventilation hole 42 similar to that of the first embodiment. Further, also in the configuration of this embodiment, a commercially available pump can be used as long as the discharge port 34a and the water supply pipe 23 are properly fitted to each other, and the repairability (pump exchangeability) is good. Further, since the vent hole 42 is provided below the high water level surface 51, even if the vent hole 42 releases water, the impact of the released water on the surroundings is small. In particular, there is an advantage that if the vent hole 23 is always located under the water surface regardless of the change of the water level, there is no influence of scattering of the discharged water to the surroundings.

(Embodiment 7) FIG. 8 is a sectional view showing the essential parts of a water supply device for a water-cooled air conditioner according to still another embodiment of the present invention. The embodiment shown in FIG. 8 is almost the same as the structure of the embodiment shown in FIG. 7, and different structures and parts will be described below, and the same reference numerals will be given to the same structures and parts and the description thereof will be omitted. In the present embodiment, the ventilation pipe 42 is provided in the water supply pipe 23 which is located above the high water level surface 51 of the toilet flush water 20 which moves up and down in the flush tank 21 when the toilet is used. In this configuration, the water 44 discharged from the ventilation hole 42 is always scattered around, so in consideration of the influence of the scattered water, the scattered water 44 is located inside the flush tank 21, that is, the scattered water is flushed with the flush tank 21. It is preferable to provide a vent hole 42 in a portion that falls inside. Even if the ventilation hole 42 is provided at a portion where the splashed water from the ventilation hole 42 falls outside the flush tank 21, for example, a configuration for providing a device for receiving the splashed water and returning it to the flush tank 21 is added. It is possible to avoid the influence of scattering. Also according to this embodiment, the ventilation hole 42 similar to that of the first embodiment is used.
By this action, the operation of the water supply pump 22 can be prevented, and the repairability can be improved by using a commercially available pump in which the discharge port 34a and the water supply pipe 23 are appropriately fitted. The leak hole 60 shown in FIG. 8 is a virtual hole that is supposed to have occurred in the water-cooled air conditioner of this embodiment. If, in the present embodiment, such a leak hole 60 occurs, the water supply pipe 23 on the water cooling condenser 12 side.
The water stored in each of the water-cooled condenser 12 and the drain pipe 24 leaks out from the leak hole 60. In this case, if the vent hole 42 exists above the high water level surface 51 as in the present embodiment, air enters through the vent hole 42, so that the water supply pipe 23 and the water-cooled condenser 12 are introduced from the part of the vent hole 42.
Only the water that has been stored between the
It will leak out. Therefore, with the configuration of the present embodiment in which the ventilation hole 42 is provided in the water supply pipe 42 at a position higher than the high water level surface, the siphon phenomenon is avoided and wasteful water supply to the flush tank 21 for the toilet and continuous water leakage. Can be prevented. The following embodiment is provided with a scattering prevention means for preventing the influence of scattering from the ventilation hole 42 which is expected when the ventilation hole 42 is provided at a position higher than the high water level surface. In the following embodiments, the same components and parts as those in the above embodiment will be designated by the same reference numerals, and the description thereof will be omitted.

(Embodiment 8) FIG. 9 is a sectional view showing the essential parts of a water supply device for a water-cooled air conditioner according to still another embodiment of the present invention. The scattering prevention means shown in FIG.
