Description

  TECHNICAL FIELD The present invention relates to a cold air generator used when spending outdoors in a room without air conditioning or in the heat, or when partially cooling the body with ice or a freezing agent in a hospital or the like.

  Traditionally, in midsummer outdoor stadiums and the like, spectators have used portable fans or refrigerated belts, cool sheets, etc., in order to prevent body temperature from rising. In addition, ice bags have been used to partially cool the affected area of patients in hospitals and the like.

  However, since the temperature is originally high in midsummer, it is not possible to obtain a satisfactory cold wind feeling with a fan. In the case where the affected area of the patient is partially cooled with ice cubes, it is difficult for the ice cubes to be continuously and freely cooled at any part of the affected area and at any angle.

  The freezing agent 19 is frozen by blowing air from the fan 39. In this case, condensed water is generated, and the condensed water is accumulated in the freezing agent storage chamber 14. Therefore, in order to discharge the accumulated dew condensation water to the outside, a dew condensation water reservoir tank 46 having a bottom is suspended from the center of the lower surface of the extended portion 27 of the box 23 so as to surround the through hole 25 on the bottom surface of the box. .

  A tip of a cold air blowing pipe 47 is connected to the upper part of the dew condensation water storage tank 46 and led out to the outside through a hole of the standing foot part 28 in the box 23, and a dew condensation water discharge port 48 is provided on the bottom surface. The drainage pipe 50 having the cap 49 is connected to this, and the condensed water accumulated in the condensed water reservoir tank 46 through the through hole 25 from the cryogen storage chamber 14 is discharged from the drainage pipe 50 to the outside. It has become so.

  The outer peripheries of the condensed water reservoir 46, the cold air blowing pipe 47 and the drain pipe 50 are covered with a heat insulating material 51 so that heat conduction from the outside is prevented as much as possible.

  As shown in FIG. 1, a cold insulation cover 52 is provided so as to cover the heat insulating material 30 and the removable lid 32. The cold insulation cover 52 is a polygonal cross-sectional body having the same shape as the heat insulating material 30, and includes a trunk portion 53 that covers the portion of the box 23, and a portion of the detachable lid 32 that is integrated with the trunk portion 53, and has an upper surface. Is formed from an opening / closing lid part 55 having a ventilation hole 54 adapted to the ventilation hole 44, and a lower end flange part 56 of the body part 53 is fixed to the extension part 27 of the box 23 by a bolt 57. 5 and 7, the chuck 58 can be opened and closed by opening and closing up to the non-chuck portion 59.

  Although the present cold wind generator may be used stationary, a portable belt 60 is attached to the outer surface of the cold insulation cover 52, and the belt 60 can be carried by hand or shoulder.

  As described above, the cold air generator is provided with the heat insulating materials 30 and 51 and the cold insulation cover 52, which are made of a material having low thermal conductivity as the material of the main body 1 and the box 23. When the frozen air freshener 19 is set in the freezer storage chamber 14 of the main body 1 and the operation of the cold air generator is stopped and not used, the frozen air freshener 19 is more effective. This is to keep it cool.

  Next, the operation will be described.

  When the fan 39 is driven, air flows from the blower pipe 40 through the blower holes 9, 12, 15 to the space 20 in the freezing agent storage chamber 14 of the main body 1, and is cooled by the freezing agent 19. The cool air sequentially flows through the air holes formed in the air blowing notches 15 and 15 of the partition wall 13 and sequentially flows through the space portions 20 in the freezing agent storage chambers 14 and is further cooled by the freezing agent 19 stored in the set. The cold air that has been finally turned into cold air flows into the condensed water reservoir 51 through the air holes 11 and 9 and the through hole 25, is led out to the outside through the cold air air duct 47, and is used for cooling the user. .

  Although cold air is obtained in this way, dew condensation occurs on the surface of the freezing agent 19 due to the blowing of outside air by driving the fan 39, and this dew condensation water drops and accumulates at the bottom in each freezing agent storage chamber 14. Condensed water naturally flows downward from the air blowing holes in the respective cryogen storage chambers 14, and flows down through the through holes 25 from the air blowing holes 11 and 9 in the final lower-stage cryogen storage chamber 14 and accumulates in the condensation water reservoir 46. .

  In the dew condensation water reservoir 46, cold air also flows, but the dew condensation water is not frozen and is cold water, so there is no effect on the cold air, but rather from using a freezing agent that progresses to weakening, The section to cold weathering will extend even a little, and the cold weathering effect will become high.

  The condensed water collected in the condensed water reservoir 46 can be drained to the outside through the drain pipe 50 even during use. However, when the drainage nears the end, the cold air will escape from the drain pipe 50. It is ideal to drain condensed water at the time of replacement.

  Then, as shown in FIG. 7, the refrigerant 19 is replaced by opening the open / close lid portion 54 by opening the cold insulation cover 52 to the non-chuck portion 59 (see FIG. 5) by the chuck 58. The detachable lid 32 is pulled out from the box 23 and separated, the main body 1 is taken out from the box 23, the rubber wacker 21 is removed, the main body 1 is divided and separated into two parts, and the respective refrigerants 19 are exchanged.

  In this embodiment, the fan 39, the power source 43, etc. are provided in the upper part of the box 23, and the cold air blower pipe 47 is provided in the condensed water reservoir 46 in the lower part of the box 23. However, the present invention is not limited to this. Since the condensed water reservoir 46 can be made compact and the fan, power supply, etc. can be made compact, a fan, a power supply, etc. are arranged at the lower part of the box 23 together with the condensed water reservoir, and the cold air blowing pipe 47 is provided. Since it can be provided at the upper part of the box 23 and the center of gravity is slightly lowered by this, the vertical placement by the bowl-like standing foot portion 28 can be made more stable.

  In addition, when the frozen air generator 19 is stopped and not used while the frozen refrigerant 19 is stored and set in the respective refrigerant storage chambers 14 of the main body 1, the inside of the main body 1 is cooled. The cold air goes down and this phenomenon is not considered in the horizontal type, but needs to be considered as the total length becomes longer in the vertical type.

  Therefore, when the cool air in the main body 1 falls, the outside air flows from the fan 39 side by the amount of the fall, and although it is a weak flow, if the cool air is discharged from the cold air blower pipe 47, it becomes useless. Therefore, in order to prevent the flow in the main body 1 and to increase the cold insulation degree, although not particularly shown, the tapered tip of the blower tube 40 to which the tapered portion of the tip of the blower tube 40 is attached has a tapered tip that is detachable. A rod-like blind plug is provided, and a cap that can be easily attached and detached is provided near the standing foot portion 28 of the cold air blowing tube 47 to achieve complete sealing of the main body 1.

  The above-described complete sealing of the main body 1 is more effective if the ventilation is blocked at two locations, but a sufficient effect can be obtained even if the ventilation is blocked at any one location.

  The cold air generating apparatus according to the present invention can be modified, and other modified modes are shown in FIGS. 9 and 10.

The flange portions 2a and 3a extending slightly outward are integrally formed at both ends in the direction, and the first main body constituting body 2 and the second main body constituting body 3 are combined at two outer peripheral portions of the flange portions 2a and 3a. These are wound by the rubber wacker 21 and maintained in the combined state.

  When these two rubber wackers 21 maintain the unity of the first and second main body constituting bodies 2 and 3 and are inserted into the box as will be described later, a gap is formed between the box and the main body 1. For this reason, the rubber wackers 21 may be provided in two places, and it is not necessary to provide a rubber wacker for preventing air leakage. However, the box is hermetically sealed, and the air pressure passing through the main body 1 and the air pressure inside the box are always equal to each other, and no air leakage occurs.

  In the cold air generator configured as described above, the air flows through the air duct 40 and the air holes 9, 11, and 15 into the space 20 in the cryogen storage chamber 14 in the main body 1 by driving the fan 39. The cooling air is cooled by the freezing agent 19, and the cooled air is passed through the ventilation holes formed in the blowing notches 15 and 15 of the partition wall 13 and sequentially passes through the space portions 20 in the freezing agent storage chambers 14. The cold air that has flowed and is further cooled by the set-containing cryogen 19 and finally cooled is led to the outside through the cooling air blowing pipe 47 from the blowing holes 9 and 11 and supplied to the user's cooling. The

  Although cold air is obtained in this way, dew condensation occurs on the surface of the freezing agent 19 due to the blowing of outside air by driving the fan 39, and this dew condensation water drops and accumulates at the bottom in each freezing agent storage chamber 14. Condensed water drops from each condensed water dropping hole 3 b in each freezing agent storage chamber 14 and accumulates between the gaps 71 with the box 61 formed by the two rubber wafers 21.

  Condensed water collected between the gaps 71 opens the cooling cover 77, removes the opening / closing lid 72 from the box 61, and gradually draws the main body 1 from the box 61 in a substantially horizontal state. 21 is discharged outside.
