Description

  The present invention is caused by a freezing agent in a cold air generating apparatus used when spending outdoors in a room without air conditioning or in a hot summer, and further when partially cooling the body using ice or a freezing agent in a hospital or the like. The present invention relates to a structure that drains accumulated condensed water to the outside.

  When the fan is driven, air flows through the air ducts and air holes to the space inside the freezing agent storage chamber in the main body, and is cooled by the freezing agent. The cooled air is sequentially stored in the freezing agents. The cold air that flows through each space in the room and is further cooled by a set of freezing agent, and finally cooled to the outside through a cold air blowing pipe, is supplied to the user for cooling. In the generator, condensation is generated on the surface of the freezing agent by blowing in the outside air, and this condensed water drops and accumulates at the bottom of each freezing agent storage chamber.

  If the amount of condensed water is small, there is no special problem. However, if a large amount of water accumulates, not only will the blown air flow worsen, but the flow of air will be disturbed and cooling efficiency will deteriorate. Cold wind is not obtained.

  Therefore, the accumulated dew condensation water must be discharged to the outside. As a method of drainage, the freezing agent storage chambers are communicated with each other to enlarge the lower space to form drainage channels. It is conceivable that the water is drained to the outside through a drain pipe or the like from the road, and the fan side is raised so that the main body faces downward, and the cold air blower pipe side is drained.

  However, in the former method using the drainage channel, the lower space of each cryogen storage chamber will be enlarged, so the internal pressure of each cryogen storage chamber will change, resulting in a difference and not equal pressure, As a result, not only the cooling efficiency is deteriorated, but it is not preferable from the flow of air.

  Further, in the latter method in which the fan side is raised and drained from the mouth on the cold air blowing pipe side, the cold air generating device becomes large, or is difficult in the case of a fixed type or a semi-fixed type.

  The problem to be solved by the present invention is that in the cold air generator, the dew condensation collected in the lower part of each cryogen storage chamber cannot be easily discharged to the outside.

  Accordingly, an object of the present invention is to provide a drainage structure for condensed water in the cool air generator that can easily drain the condensed water accumulated in the lower part of each cryogen storage chamber to the outside. .

As a result, a blower hole is formed in the center of each partition wall 10, 11 by the upper and lower blowout notches 14, 15. And in order to maintain this united state, rubber or a spiral spring backer 17 is wound around the outer periphery of the main body 1 at a suitable position.
