DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor air conditioner for reducing daytime power consumption by utilizing nighttime power.

[0002]

2. Description of the Related Art Generally, the amount of electricity used at night is much smaller than at night. If this nighttime electricity consumption is increased and the difference in daytime and nighttime electricity consumption is reduced, power supply at a lower cost becomes possible by rationalizing the power supply facilities and increasing the efficiency of operation at the power company. Also, especially in the summertime during the daytime, power consumption peaks due to excessive operation of coolers in offices and homes, etc.
There is a possibility that the supply limit will be exceeded. For this reason, various regenerative air conditioning systems that use nighttime electricity
Its spread is being promoted.

As such a regenerative air conditioning system, for example, the one shown in FIG. 3 is used. This system freezes ice in the ice heat storage tank 20 with electric power at night and uses the cold stored in the ice as cooling energy for the air conditioner 21 in the daytime. This allows the air conditioner 2

However, the heat storage type air conditioning system has a problem that complicated and large-scale equipment such as a large ice heat storage tank 20 and a heat pump 22 is required, and the equipment cost becomes extremely high. In addition, the ice heat storage tank 20 is often installed on the roof or basement of a building or the like,
It is difficult to install it easily in an existing building or the like, and it requires extremely high construction costs. In reality, it is necessary to consider the introduction from the design stage of the building and the like. Moreover, even if the above system is installed and used, the power used by the air conditioner 21 in the daytime is not cut by 100%, and there is a gap between the introduction cost and the power cost reduction effect. It is. For this reason, at present, the above-mentioned conventional thermal storage type air conditioning system has hardly spread, and development of a compact device which is inexpensive and can be installed even in a narrow place is desired.

The present invention has been made in view of such circumstances, and provides a compact indoor air conditioner that uses nighttime power to reduce daytime power consumption and that can be installed inexpensively and in a narrow place. With that purpose.

[0006]

In order to achieve the above object, an indoor air conditioner according to the present invention comprises an ice maker for producing ice with nighttime electric power and a transparent container for storing ice produced by the ice maker. The gist of the invention is that the transparent container is formed in a vertically long cylindrical shape.

That is, the indoor air conditioner of the present invention is provided with an ice maker for producing ice with nighttime electric power and a transparent container for storing ice produced by the ice maker. Then, ice is produced with electric power at night, stored in a transparent container, and the transparent container filled with ice is installed in a room during the daytime, and the indoor air is cooled with a large amount of ice and the transparent container is cooled. A large amount of ice that can be seen through can provide a visual refreshment. Thereby, even if the set temperature of the air conditioning in the daytime is slightly increased, the heat is not psychologically felt, and the power consumption in the daytime can be reduced. In this way, complicated and large-scale facilities such as a large ice heat storage tank and a heat pump are unnecessary,
Equipment costs are significantly reduced. In addition, it can be easily installed in existing buildings and rooms, and can be easily moved. Further, in the indoor air conditioner of the present invention, since the transparent container is formed in a vertically long cylindrical shape, the indoor air conditioner can be installed in a narrow place without taking up a place. In this way, despite the low installation cost and simple operation, there is a power cost reduction effect and the compact size
The effective use of nighttime power is promoted, and the peak of daytime power usage charges is suppressed.

[0008] In the indoor cooling machine of the present invention, the ice maker includes:
When the air conditioner is disposed on the upper side or the lower side of the transparent container, the indoor air conditioner itself is further compacted and does not take up much space.

In the indoor air conditioner of the present invention, when a cylindrical heat insulating material is inserted into the outer periphery of the transparent container so as to be movable up and down, ice is produced with nighttime electric power and stored in the transparent container. It is difficult to melt, and the ice can be quickly filled in the transparent container, and the size of the ice maker can be reduced. In the daytime, the insulation can be moved to cover equipment such as ice machines, so that cluttered equipment can no longer be seen from the outside and has a neat appearance, and noise generated by equipment can be reduced.

Next, embodiments of the present invention will be described in detail.

FIG. 1 shows an embodiment of an indoor air conditioner according to the present invention. In this indoor cooling machine, a transparent container 2 formed in a vertically long cylindrical shape is disposed on a frame 11, and an ice maker 1 is disposed above the transparent container 2. The dimensions of the transparent container 2 and the dimensions of the frame 11 are set to be substantially the same. The ice maker 1 freezes water with electric power at night to produce ice, drops the ice into a transparent container 2 (arrows in the drawing), and stores the ice in the transparent container 2. A cylindrical heat insulating material 12 made of styrene foam or the like is fitted around the outer periphery of the transparent container 2 so as to be vertically slidable.

A drain hose 9 communicates with the bottom surface of the transparent container 2 so that water formed by melting ice is introduced into the water supply / drainage tank 4 and collected. Reference numeral 10 denotes a filter for filtering water collected in the water supply / drainage tank 4 from the bottom surface of the transparent container 2. The water supply / drainage tank 4 is provided with a water supply path 5 for supplying new water and a drainage path 6 for draining water in the water supply / drainage tank 4. 5a and 6a are cocks.

Reference numeral 3 denotes a pump for pumping the water to the ice making machine 1 via a pumping path 7 when a certain amount of water is stored in the water supply / drainage tank 4. The pumping path 7 is provided so as to penetrate the bottom surface of the transparent container 2 and penetrate substantially the center of the cylindrical transparent container 2. Thus, with the ice stored in the transparent container 2, the pumping path 7 is hidden by the ice and cannot be seen from the outside.

In the above configuration, the indoor air conditioner of the present invention can be used, for example, as follows. That is, first, water is introduced into the water supply / drainage tank 4 from the water supply path 5, and the water is pumped up by the pump 3 and introduced into the ice making machine 1 through the path 7. Then, the water is frozen by the ice maker 1 to produce ice, which is dropped into the transparent container 2. These electric powers are generated using nighttime electric power, and the production of ice is continued at night until the transparent container 2 is filled with ice. At this time, since the heat insulating material 12 is fitted around the outer periphery of the transparent container 2, the ice in the transparent container 2 is hardly melted, and
The inside can be filled with ice, and the ice making machine 1 can also be reduced in size.

In the daytime, the heat insulating material 12 is slid downward (indicated by a dashed line in the figure) to expose the transparent container 2 filled with ice. An indoor air conditioner is installed indoors with the transparent container 2 filled with ice, and the indoor air is cooled by the ice. In addition, a large amount of ice seen through the transparent container 2 gives a visual refreshing feeling. At this time, since the pumping path 7 is hidden by ice and cannot be seen from the outside, the visual refreshing feeling is not impaired. Further, the frame 11, the pump 3, etc.
, The cluttered devices become invisible from the outside and have a clean appearance, and the noise generated by the pump 3 and the like is reduced.

The water formed by melting the ice is collected in the water supply / drainage tank 4 through the drain hose 9, pumped again by the pump 3, introduced into the ice making machine 1, and reused. At this time, a filter 10 is provided at the entrance of the drain hose 9 to remove dust mixed in the water, so that the production of dirty ice is prevented and the visual refreshing feeling is not spoiled. I have.

As described above, according to the indoor air conditioner, even if the set temperature of the air conditioning in the daytime is slightly increased, the heat is not psychologically felt, and the power consumption in the daytime can be reduced. For example, in the conventional ice thermal storage air conditioning system, the power consumption during the daytime can be reduced to about 30 to 40%, but a huge installation cost is required, whereas the indoor air conditioner of the present invention is extremely inexpensive. The daytime power consumption can be reduced to about 70 to 80% at a low introduction cost, which is excellent in cost-effectiveness.

In addition, complicated and large-scale equipment such as a large ice heat storage tank and a heat pump are not required, the equipment cost is low, and the apparatus can be easily installed in an existing building or room. Further, in the indoor cooling device, the transparent container 2 is formed in a vertically long cylindrical shape,
Since the ice maker 1 is provided on the upper side of the transparent container 2, the ice maker 1 can be installed in a small place without taking up a place. Furthermore, since the water formed by melting the ice in the transparent container 2 is collected, introduced again into the ice maker 1, and circulated, the amount of water used is reduced and the running cost is reduced.

FIG. 2 shows a second embodiment of the indoor air conditioner of the present invention. In this indoor air conditioner, an ice maker 1 is provided in a frame 11 below a transparent container 2. Further, the water in the water supply / drainage tank 4 is introduced into the ice making machine 1 without passing through the pump 3. The indoor air conditioner is provided with an ice supply pipe 12 extending from the ice maker 1 through the bottom of the transparent container 2, extending substantially at the center of the transparent container 2 upward, and opening near the lid 16 of the transparent container 2. ing. Otherwise, it is the same as that shown in FIG. 1, and the same parts are denoted by the same reference numerals.

In the indoor cooling machine, the ice produced by the ice maker 1 is pushed upward in the ice supply pipe 15 and is supplied into the transparent container 2 from the upper end opening (shown in the figure). Arrow). And the ice supply pipe 15
Is disposed substantially at the center of the transparent container 2, and when the transparent container 2 is filled with ice, the ice supply pipe 15 is hidden by ice and cannot be seen from the outside, so that the visual refreshing feeling is not impaired. It has become. Other than that, the same operation and effect as those shown in FIG. 1 are obtained.

In each of the above embodiments, the water supply / drainage tank 4 for supplying and discharging water is provided to circulate the water for producing ice. However, the present invention is not limited to this. And the water for producing ice may not be circulated. The ice produced by the indoor air conditioner of the present invention includes ice of various shapes such as dice, flakes, and blocks, and includes ice of various colors such as transparent and white, and is particularly limited. is not. Also.
The ice maker 1 of the indoor air conditioner of the present invention is intended to include various types such as a drum type, an auger type, and a vertical type, and is not particularly limited.
