Description

[Detailed description of the invention] <Industrial application field> This invention is a ceiling dew condensation prevention device that prevents dew droplets from adhering to the ceiling in indoor environments where large amounts of steam are generated, such as kitchens, food factories, and bathhouses. Regarding.

<Conventional technology> In places where a large amount of steam is generated, such as kitchens, food factories, or bathhouses, most of the steam rises to the ceiling and stays there, so it is especially difficult to do so in winter when the ceiling surface is cold. Condensation forms on the ceiling surface, and the dew drops fall from the ceiling, making it unhygienic and causing mold to grow on the ceiling.

<Problem that the invention aims to solve> Therefore, conventionally, in kitchens, food factories, etc. where steam is generated, ventilation doors have been installed to exhaust indoor steam.
The problem was that the ventilation door could only exhaust steam from the vicinity, leaving a considerable amount of steam remaining near the ceiling, making it impossible to effectively prevent condensation on the ceiling.

<Means for solving the problem> The present invention was developed in consideration of the above points, and it generates airflow in a certain direction along the ceiling surface, dehumidifies the moisture contained in the air, and cleans the ceiling. The present invention provides a ceiling dew condensation prevention device that can effectively prevent dew condensation from occurring on surfaces, and is configured as follows.

That is, the ceiling condensation prevention device of the present invention is a ceiling blower device in which a blower is disposed within a cylindrical body, an air outlet is provided at the rear, and a blow-up plate is provided at the lower edge of the air outlet. The dehumidifier consists of a duct-shaped body with an air blower and a radiator-type cooler, multiple intake ports on the side of the body, and an air outlet at the end of the body. Attached to the ceiling,
The ceiling blower is configured to be attached to a ceiling surface so as to blow air toward the intake port of the dehumidifier.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

1 and 2 show cross-sectional views of a dehumidifying device 1 used in a ceiling condensation prevention device, and this dehumidifying device 1 is equipped with a duct-like main body 2. As shown in FIG. The front end of the duct-like main body 2 is open to form an air supply port 3, the rear end is closed, and a plurality of circular air intake ports 4 are formed on both sides of the rear half of the duct main body 2. A blower 5 is installed near the air outlet 3 in the duct-like main body 2 so as to send out the internal air from the air outlet 3. Behind the blower, a radiator-type cooler 6 is installed. A mist filter 7 is installed behind the filter 6. A refrigerant such as cooling water or fluorocarbon gas is flowed through the cooling pipe of the cooler 6 to cool the fins, and the cooling causes steam to condense on the fins and the pipe. Water droplet receiver 8 is located below the cooler 6 and mist filter 7.
A drain pipe 9 is connected to the water droplet receiver 8.

Figure 3 shows a ceiling blower 10 attached to the ceiling surface.
This ceiling blower device 10 has two blowers 12 arranged side by side in a cylindrical body 11, an air outlet 13 at the front and an air intake 16 at the rear.
It is formed by providing a blow-up plate 14 on the lower edge of 3.
Further, a wind direction plate 15 that adjusts the wind direction in the left and right directions is provided in the cylindrical body 11 so that the angle can be adjusted, and when the ceiling blower device 10 is attached to the ceiling surface and blows air,
The blow-up plate 14 and the wind direction plate 15 are configured to form an air flow along the ceiling surface.

The dehumidifier 1 and the ceiling blower 10 configured in this way are, for example, as shown in FIGS. 4 and 5,
It is installed on the ceiling of a room where a large amount of steam is generated, such as a kitchen. That is, in the case of a rectangular ceiling surface, the dehumidifier 1 is installed approximately in the center of the ceiling surface in the short direction, and the four ceiling blower devices 10 are installed on the ceiling surface near the four corners of the room. They are respectively installed with the ports 13 facing the air intake ports 4 of the dehumidifier 1. When such a device is operated in a kitchen or the like, the air containing a large amount of steam accumulated near the ceiling is sent by the ceiling blower 10 toward the dehumidifier 1 in the center, thereby blowing the duct-shaped main body of the dehumidifier 1. 2, the air near the entire ceiling surface is taken in relatively evenly. The air containing moisture sucked into the duct-like main body 2 passes through a mist filter 7 and a cooler 6,
At this time, moisture in the air adheres to the surfaces of the mist filter 7 and the fins of the cooler 6 to form dew condensation, and water droplets fall into the water droplet receiver 8. The air dehumidified by the mist filter 7 and cooler 6 is sent out from the air outlet 3 by the blower 5, and this air hits the wall and spreads, resulting in air near the ceiling surface as shown in Figure 5. A circulating flow is formed, and moist air such as steam rising from below is immediately sucked into the dehumidifier 1 and the moisture is removed. Also, at this time, the dehumidifier 1 is installed on the ceiling surface, and each ceiling air blower 1
Since the air sent out from the ceiling is always flowed along the ceiling surface by the action of the blow-up plate 14, dew condensation on the ceiling surface is effectively prevented.

Note that the mist filter 7 in the dehumidifier 1 is not used, and a considerable dehumidifying effect can be obtained by using the cooler 6 alone, and the air intake port may be provided only on one side of the duct body 2.

<Effects of the invention> As explained above, the ceiling condensation prevention device of the present invention has a blower inside the cylindrical body, an air outlet at the front and an air intake at the rear, and an air outlet under the air outlet. A ceiling blower with a blow-up plate on the edge, a blower and a radiator-type cooler inside the duct body, multiple air intake ports on the side of the main body, and an air outlet at the end of the main body. The dehumidifier is attached to the ceiling, and the ceiling blower is attached to the ceiling so as to blow air toward the intake port of the dehumidifier. Therefore, a circulating air flow is formed that flows from the ceiling blower to the dehumidifier along the ceiling surface, and the steam rising from below is caught up in this air flow and sucked into the dehumidifier, where it is dehumidified. Even in kitchens where a large amount of steam is generated and cannot be exhausted by ventilation doors alone, steam and moisture can be effectively removed and condensation on the ceiling can be effectively prevented, eliminating unhygienic mold and dew droplets. can be prevented.
