The present invention relates to a mobile cooling air device.

[Conventional technology]

In recent years, air conditioning equipment has become popular in factories to improve the working environment. However, instead of a fan, a mobile cooling air device that locally cools the room is also used. As shown in FIG. 3, the mobile cooling air device basically has the same structure as the above-mentioned cooling equipment, and is a small-sized cooling equipment. In addition, the code 30 in the figure
31 is a compressor that compresses low-temperature, low-pressure refrigerant gas and converts it into high-temperature, high-pressure refrigerant gas; 31 is a condenser that cools and liquefies the high-temperature, high-pressure refrigerant gas discharged from the compressor 30; 32 is an evaporator that absorbs ambient heat by gasifying the liquefied refrigerant; 33 to 35 are refrigerant pipes; 36 is a fan for cooling the condenser; 37 is for the evaporator 32; Forced cold air fan, 3
8 represents a drain pipe, and 39 represents a water receiving tank.

Since the cooling cycle operation of the mobile cooling air device shown in FIG. 3 is well known, a description of the operation will be omitted, but a conventional mobile cooling air device is shown in FIG. The conventional example shown in FIG. 4 has the above-mentioned components shown in FIG. 3 inside a so-called cabinet type device casing 40, namely a compressor 30, a condenser 31, an evaporator 32, refrigerant pipes 33 to 35, and a condenser cooling device. Juan 36,
Cold air fan 37, drain pipe 38, water tank 39
etc. (all not shown) are built-in. A cold air outlet 41 is provided on the front of the device casing 40, an outside air inlet 42 is provided on the side, and a hot air outlet (not shown) is provided on the back.

From the cold air outlet 41, the cold air fan 3
7 performs forced air blowing to the evaporator 32, heat of the forced air is absorbed by the evaporator 32 and changes to cold air, and the cold air is sent out.

The hot air outlet (not shown) connects the condenser 3 with the condenser cooling fan 36.
The hot air that has absorbed the heat of the condenser 31 is discharged. Further, wheels 43, . . . are attached to the device casing 40, so that it can be moved to any desired position.

[The problem that the idea aims to solve]

The conventional example described above has the following undesirable problems. That is, all of the components are housed in a so-called cabinet-type device casing 40, and the position of the cold air outlet 41 is always constant, so there is an inconvenience that the position of the cold air outlet cannot be changed arbitrarily.

In order to solve this problem, the cold air outlet 4
It is also being considered to install a guide vane in 1 to adjust the direction of cold air blowing out.
It is only possible to change the direction in which the cold air is blown out, but it is not possible to change the position in which the cold air is blown out in the height direction itself.

Since all of the components are integrated into a so-called cabinet-type device housing 40, it is large and, especially when used in a small room, not only does it take up space, but it is also inconvenient because it is difficult to turn around. .

[Means to solve the problem]

The purpose of the present invention is to solve the above-mentioned problems, and therefore, the mobile cold air device of the present invention blows cold air to a refrigerant compressor, a condenser, an evaporator, and the evaporator. A mobile cold-air device equipped with a cold-air fan that generates a cold-air fan, which includes a device main body in which at least the refrigerant compressor and condenser are built-in, the evaporator and the cold-air fan built-in, and air blown by the cold-air fan. a cold air sending part formed with a cold air outlet for sending out the cold air to the outside, and a support member supporting the cold air sending part at one end and rotatably attached to the main body of the apparatus at the other end, consists of an upper strut, a lower strut, and a joint portion that connects the upper strut and the lower strut, and is characterized in that the upper strut and the lower strut are configured to be freely bendable via the joint portion. .

Further, the device main body includes at least the refrigerant compressor, condenser, evaporator, and cold air fan built therein, and the support member is formed of a flexible duct having a cavity inside,
It is characterized in that the cold air is configured to pass through the inside of the support member and is sent out from the cold air sending section.

Embodiments of the present invention will be described below with reference to the drawings.

〔Example〕

FIG. 1 shows an external view of one embodiment of the present invention, and FIG. 2 shows an external view of another embodiment of the present invention.

The mobile cooling air device of the present invention basically has a configuration similar to that shown in FIG. 3.

Reference numeral 1 in the illustrated embodiment in FIG. 1 indicates the main body of the device;
2 is a cold air sending part, 3 is an upper support, 4 is a lower support,
5 is a joint part, 6 is a flange part, 7 is a piping part, 8 is a cold air outlet, 9 is an outside air inlet, and other symbols correspond to those in FIG. Although not shown, the apparatus main body 1 includes a compressor 30, a condenser 31, a condenser cooling fan 36, a water tank 39, etc. shown in FIG. includes an evaporator 32 and a cold air fan 3.
7 mag is built in. A piping section 7 formed of a flexible tube is disposed along the upper support 3 and lower support 4, and inside the piping section 7, although not shown, there is a refrigerant as shown in FIG. 3. Pipes 34 and 35, drain piping 38, electric wires for power supply to the cold air fan 37, and the like are flexibly housed.

The cold air sending section 2 is supported by the main body 1 of the apparatus via an upper support 3 and a lower support 4 connected by a joint 5. The lower support column 4 is fixed to the device main body 1 at a flange portion 6 so as to be rotatable in the direction of the arrow shown in the figure. Also,
The upper strut 3 is configured to be bendable in the direction of the arrow shown in the figure, using the joint portion 5 as a fulcrum. Therefore, since the cold air blowing section 2 is movable in the vertical direction (height direction) and horizontal direction, the cold air blowing position can be freely adjusted. In addition, by lengthening the upper support 3 and/or the lower support 4 to increase the distance between the cold air sending section 2 and the device main body 1, the cold air blowing position can be moved far from the blowing position of the exhaust hot air from the condenser 31. Since it is possible to separate them, the cold air effect can be enhanced.

Although the cooling cycle operation of the embodiment shown in FIG. 1 is well known, it will be briefly explained below. That is, high-temperature, high-pressure refrigerant gas compressed by the compressor 30 built into the device main body 1 is liquefied in the condenser 31 . The liquefied refrigerant liquefied in the condenser 31 is sent to the evaporator 32 built in the cold air delivery section 2 via a refrigerant pipe 34 installed in the pipe section 7 . In the evaporator 32, the heat of the forced air from the cold air fan 37 is absorbed and gasified. That is, the heat of the forced air from the cold air fan 37 is absorbed by the evaporator 32 to become cold air, which is then sent out from the cold air outlet 8 to the outside. The low-temperature, low-pressure refrigerant gas gasified in the evaporator 32 is sent to the compressor 30 via a refrigerant pipe 35 installed in the pipe section 7. Note that water droplets generated during heat exchange by the evaporator 32 are collected in a water receiving tank 39 built into the device main body 1 via a drain pipe 38 installed in the pipe section 7.

The embodiment shown in FIG. 2 is constructed so that all of the compressor 30 to water tank 39 shown in FIG. 3 are housed in the main body 1 of the apparatus in a compact manner. The hollow flexible duct 10 is configured to support the cold air outlet 2.
The cold air generated by the evaporator 32 passes through the flexible duct 10 from the device main body 1 and is sent out from the cold air delivery section 8 provided in the cold air delivery section 2 . Note that the cold air sending section 2 in the illustrated embodiment in FIG. 2 is the same as the cold air sending section 2 in the illustrated embodiment in FIG.
Unlike, since there is no need to install any devices such as an evaporator 32 and a cold air fan 37 inside, the cold air sending section 2 can be made small and lightweight. Therefore, the rigidity of the flexible duct 10 is not particularly necessary, and it is possible to provide sufficient flexibility. Further, the flexible duct 10 is fixed to the apparatus main body 1 at the flange portion 6 so as to be rotatable in the direction of the arrow shown in the figure, similarly to the embodiment shown in FIG. That is, the cold air sending section 2 is supported by a flexible duct 10 that has sufficient flexibility and is configured to be freely rotatable in the direction of the arrow in the figure, so that the cold air blowing position and blowing direction can be freely controlled. can be adjusted to Furthermore, by lengthening the flexible duct 10 and increasing the distance between the cold air sending section 2 and the device main body 1, the cold air blowing position can be moved far away from the exhaust hot air blowing position from the condenser 31. Therefore, the cold air effect can be enhanced.

In the embodiments illustrated in FIGS. 1 and 2 described above, the device main body 1 is provided with wheels 43, . . . , respectively, so that the installation position can be moved freely.
It should be noted that the method of moving the installation position described above may be made self-propelled by applying robot technology, and the method of rotating the lower support 4 in the embodiment shown in FIG. 1 and the flexible duct 10 in the embodiment shown in FIG. It is also possible to use an automatic system, and by doing so, the installation position and the cold air blowing position can be adjusted by remote control, making it even more convenient.

[Effect of idea]

As explained above, according to the present invention, it is possible to provide a mobile cooling air device having the following excellent effects. That is, the blowing position and blowing direction of the cold air can be freely adjusted without moving the main unit.

Because it can be made smaller and lighter,
The manufacturing cost can be reduced, and the installation position can be easily moved.

By lengthening the strut member that supports the cold air sending unit and increasing the distance between the cold air sending unit and the main unit, the cold air blowing position can be moved far away from the exhaust hot air blowing position from the condenser. , can enhance the cold air effect.

By using a self-propelled method to move the above-mentioned installation position by applying robot technology and using an automatic method to rotate the above-mentioned support member, the above-mentioned installation position and cold air blowing position can be adjusted by remote control. .
