Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anemo type ceiling air-conditioning air outlet, and more particularly to a structure for preventing dew condensation caused by a difference between room temperature and outlet temperature.

[0002]

[Prior art]

 Conventionally, during cooling, conditioned air from an air conditioner that uses cold water as a medium has been blown into the room from the ceiling air conditioning air outlet. In this case, since the cooling capacity of the air conditioner is not high and the temperature of the conditioned air does not drop below a certain temperature, it is unlikely that water vapor in the room air will be cooled and that dew condensation will occur inside the air conditioning air outlet of the air conditioning system. . Recently, however, air conditioners that use a refrigerant, which is a gas that is easily liquefied during cooling, are increasingly used. In this case, the cooling capacity is higher than that of a conventional air conditioner using cold water as a medium, and it becomes possible to use air conditioning air with a low temperature. When air-conditioned air whose temperature is lower than a certain temperature is used, water vapor in the indoor air is cooled, and condensation is likely to occur inside the ceiling air-conditioning air outlet.

[0003]

[Problems to be solved by the device]

 However, if dew condensation occurs on the ceiling air-conditioning air outlet, water droplets may fall inside the room and wet the people inside or in the room. In particular, the middle cone inside the ceiling air-conditioning air outlet has a small surrounding area, so it is easy to be cooled, so there was the problem that the frequency of dew condensation increased. Therefore, if condensation occurs, measures are taken such as raising the temperature of the conditioned air or warming the middle cone with a heating wire provided inside the ceiling air conditioning air outlet.In this case, the temperature of the conditioned air is raised. This would violate the purpose of using an air conditioner with high cooling capacity, and if a heating wire was installed inside the ceiling air conditioning air outlet to heat the middle cone, wiring from the power supply would be required, resulting in a significant increase in cost. Was invited.

The present invention aims to solve the above problems and prevents the formation of dew condensation in the middle cone without raising the temperature of the conditioned air or installing a heating wire or the like inside the ceiling air conditioning air outlet. However, it is intended to provide a structure that prevents the inside of the room from getting wet due to the drop of water drops caused by dew condensation.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises an outer cone and a middle cone which is concentrically arranged in the outer cone. Place the flat plate so as to close it, fit the packing around the circumference of the flat plate and the circumference of the middle cone over the entire circumference, and detachably attach the flat plate to the middle cone with the packing. An airtight space is formed between the middle cone and the flat plate.

[0006]

[Action]

 According to the above configuration, since the airtight space is formed inside the middle cone, even if conditioned air having a temperature below a certain temperature flows into the ceiling air conditioning air outlet, the inside of the middle cone contains water vapor in the room. No air enters, so no condensation occurs. Therefore, it is possible to prevent the room and people in the room from getting wet. Further, compared to the case where a heating wire or the like is provided inside the ceiling air-conditioning air outlet, the wiring from the power supply is unnecessary, so that the cost can be reduced.

【Example】

 The present invention will be described below based on embodiments. As shown in FIG. 1, an anemo type ceiling air-conditioning air outlet 1 is buried in a ceiling 2 and supplies air-conditioning air from an air conditioner to the room. The ceiling air-conditioning air outlet 1 is a cylindrical neck 3 that is provided vertically to the ceiling 2 surface and that receives the air-conditioning air from the air conditioner first, an outer cone 4 with open upper and lower surfaces, and an outer cone 4. And an upper part of the outer cone 4 and an upper part of the middle cone 5 are fixed in the joint box 6. The middle cone 5 is a metal member whose upper and lower surfaces are square and whose lower surface has an opening 5a wider than the upper surface. Like the middle cone 5, the outer cone 4 is a metal member whose upper and lower surfaces are square, the lower face is wider than the upper face, and each edge of the lower face is attached to the opening of the ceiling 2. There is. The conditioned air supplied from the air conditioner through the neck 3 is blown into the room from the space 7 between the outer cone 4 and the middle cone 5.

A flat plate 8 is detachably attached to the opening 5a on the lower surface of the middle cone 5, and the flat plate 8 closes the opening 5a. The flat plate 8 is, for example, a substantially square member made of acrylic or the like and is substantially transparent, and a rubber packing 9 is fitted to the peripheral portion thereof. As shown in FIGS. 2A and 2B, the packing 9 is sealed so as to sandwich the edge of the opening 5a and the peripheral portion of the flat plate 8, so that the flat plate 8 is opened from below from the opening 5a of the middle cone 5. Can be attached closely to. The middle cone 5 forms a hermetically sealed space inside by the flat plate 8 being sealed by the packing 9 in the opening 5a.

When the conditioned air from the air conditioner having a temperature equal to or lower than a certain temperature blows out from the space 7 into the room through the neck 3, the middle cone 5 is also cooled. Since the surrounding area of the middle cone 5 is small, it is easy to be cooled by the conditioned air, and when the opening 5a is left open, the water vapor contained in the room air is cooled to form water droplets, and the middle cone 5 is cooled. It adheres easily to dew. However, since the opening 5a of the middle cone 5 is sealed by the flat plate 8 by the packing 9 to form an airtight space, even if the middle cone 5 is cooled, the water vapor in the air in the room will remain in the middle cone 5. It does not enter inside and does not cause condensation. Therefore, water droplets due to dew condensation will not drop and wet the room or people in the room.

Although the case where the opening 5a is square is described in the above embodiment, the same effect is obtained even when the opening 5a is circular as shown in FIG. The flat plate 8 is made of a transparent material such as acrylic so that it can be provided on the ceiling 2 without any discomfort and the appearance is not spoiled.

[0011]

[Effect of device]

 As described above, the present invention includes the outer cone and the middle cone concentrically arranged in the outer cone, and the downward opening of the middle cone closes the opening. A flat plate is placed, and packing is fitted around the entire circumference of the flat plate and the peripheral part of the middle cone, and the flat plate is detachably attached to the middle cone with the packing. Since an airtight space is formed between the flat plate and the flat plate, it is possible to prevent the inflow of room air-containing steam into the middle cone. Therefore, conditioned air below a certain temperature will flow in from the neck, and even if the middle cone is cooled, there will be no condensation, and water droplets of condensation will not drop into the room and wet the room or people in the room. Has the advantage. Moreover, since the flat plate can be easily attached from below the ceiling with packing, it is easy to replace it, and wiring is unnecessary compared to the case where a heating wire or the like is provided, so that the cost can be kept low. Have.
