Abstract

(57) [Summary] [Purpose] To cool articles hygienically. [Structure] A filter 3 is inserted into a blowout duct 2 of a spot type air conditioner 1 and attached together with the duct. This prevents dust from directly blowing on the cooling object.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a local cooling machine with a filter that prevents dust from directly blowing onto a symmetrical object.

[0002]

[Prior art]

 Even cooling symmetrical objects such as foods and chemicals that do not like dust are conventionally blown with cold air to cool such articles.

[0003]

[Problems to be solved by the device]

 When the cold seal is directly blown onto the cooling object in this way, dust adheres to the article, which is a sanitary problem.

The present invention aims to solve this drawback in a simple way and to cool the article hygienically.

[0005]

[Means for Solving the Problems]

 The present invention has been made in order to achieve the above object, and its gist is that a filter is inserted into a blowout duct in a spot type air conditioner and is attached together with the duct.

[0006]

[Work]

 Since a filter is installed in the blowout duct of the spot type air conditioner, even if dust or the like is contained in the cool air blown out from the air conditioner, it will be removed by the filter in this duct and only clean cool air will be blown at the end of the duct. More blown out. For this reason, food and chemicals that hate dust can be cooled hygienically, and the removable filter allows easy cleaning and replacement of the filter.

【Example】

 A local cooling machine with a filter according to the present invention will be described below with reference to the illustrated embodiment. In the figure, reference numeral 1 is a local air conditioner (spot type air conditioner) having a desired capacity, and a desired length, preferably flexible, duct 2 for blowing cold air to the local air conditioner 1 is attached to the air conditioner 1. Is to fix the mounting flange 2F, which is fixed to the base end of the duct, to the air conditioner with screws as in the conventional case.

Further, a filter 3 having a desired mesh is inserted and attached in the blowout duct 2. The filter 3 has a conical shape and is attached directly to the blowout duct 2 or is sandwiched between the blowout duct and the air conditioner.

1 and 3 show a method of sandwiching the filter 3 between the base end of the blowout duct 2 and the air conditioner. This is a mounting flange on the outer periphery of the mouth of the filter 3 as shown in FIG. 3F is integrally provided, and this flange 3F is sandwiched between the cooling machine 1 and the mounting flange 2F of the blowout duct 2, and when the mounting flange 2F of the blowout duct is fixed with a screw, both are fixed. The attached state is as shown in FIG.

When the filter 3 is attached to the tip of the blowout duct 2 as shown in FIG. 2, various methods of attaching the filter 3 can be considered. In the structure shown in FIG. 4, mounting claws 4 are provided on the outer periphery of the filter mouth at a plurality of positions at predetermined intervals along the circumferential direction, and the mounting claws 4 are hooked on the outer periphery of the air outlet duct to mount the filter 3 thereon. Insert into the outlet duct and attach as shown in Fig. 6. Note that FIG. 5 shows the mounting claw piece 4. This is made of an elastic material in the shape of a clip, and is thereby clamped at the tip of the blowing duct.

In FIGS. 7 and 8, a tightening band 5 is integrally provided at the filter mouth, the filter 3 is inserted into the tip of the outlet duct, and then the mouth of the filter is folded back to the outer periphery of the tip of the outlet duct. To surround. Then, the folded fastening band 5 is fastened to fix the filter, and this mounting state is shown in FIG.

[0012] Therefore, as described above, the conical filter is inserted into the duct on the base end side or the tip end side of the blow-out duct and is attached through the mouth portion thereof. Even if dust is mixed in the cold air, it is removed by the filter in the air outlet duct, and clean cool air is blown out from the tip of the air outlet duct, so it can be safely used for food and chemicals that do not like dust.

In addition, if the filter is clogged with dust removed by use, in the embodiment provided on the base end side of the blowout duct, the filter is also removed by loosening the screw and taking out the blowout duct. It can be easily removed and cleaned, or replaced with a new one. When it is attached to the tip of the blow-out duct 2, the filter 3 can be easily removed and cleaned by removing the attachment claw piece 4 or loosening the tightening band 5.

[0014]

[Effect of device]

 The local air conditioner with a filter of the present invention is a spot type air conditioner, in which a filter is inserted into the blowout duct and attached together with the duct, so that the dust contained in the cold air can be easily removed, the cold air becomes clean, and foods and chemicals can be cleaned. It has the advantage that it can also be used for cooling items that dislike dust.
