水七使用すればＯ″Ｃの氷として潜熱（融解熱で８０Ｋ
ｃａＡ／水１ｋｇ）を蓄えられる。In the conventional heat pump cycle, a compressor 3, a condenser 4, a throttle device 6, and an evaporator 7 are sequentially connected through piping as shown in FIGS. 1 to 3 to form a heat pump cycle, which is housed in a casing 2. Air is sucked in from the suction port 9 at the lower center and distributed in opposite directions; on the one hand, it passes through the condenser 4 by the air blower 5 and is discharged as hot air to the hot air discharge port 10; The fan 8 passes through the evaporator 7 and turns into cold air, which is discharged from the cold air outlet 11 and used as air conditioning. The evaporator 7 is equipped with a heat storage function, and its structure is shown in FIG. 4 as an example. This is a fin-tube heat exchanger in which a heat storage material 23 is sealed between the fins 22, and the cold heat of the evaporator 7 can be stored. For example, if water is used as the heat storage material 23, it will generate latent heat (heat of fusion of 80K) as ice at O''C.

おく。使用する時はファン８を作動させて、蓄えておい

風温度も一層低くなり、より効果的な冷涼感を得ること
ができるわけである。When this is used as a spot cooler, and the spot cooler is not used, the fan 8 is stopped, heat is taken from the heat storage material 23 of the evaporator 7, water is changed into ice, and cold heat is stored. When in use, the fan 8 is operated to instantly release the stored cold heat as a large amount of cold heat. As a result, the temperature of the cold air becomes even lower, and a more effective cooling sensation can be obtained.
ところが従来例では、この蓄熱時にファン８を停止させ

。つまり蓄熱効率が悪く、水が氷になる時間が非常に長
くかがり、最悪水にならない場合もある。However, in the conventional example, if the fan 8 is stopped during this heat accumulation, the fan 5 on the condenser side
This causes air to be sucked in from the discharge port 11 as well, and since the air passes through the evaporator 7, heat is used to lower the temperature of this air, making it difficult for water to turn into ice. In other words, the heat storage efficiency is poor, and it takes a very long time for water to turn into ice, and in the worst case, it may not turn into water at all.

量だけ冷風吐出口１１より暖かい空気が吸い込まれる。The gist of the present invention is that a heat pump consisting of a compressor, a condenser, a throttle device, an evaporator equipped with a heat storage function, etc. is housed in a casing, and air sucked in from the suction port at the bottom of the casing passes through the condenser. In spot coolers, where the air passes through an evaporator with a heat storage function to become hot air, and on the other hand passes through an evaporator with a heat storage function to become cold air, which is then discharged into the room, a partition plate is installed to divide the inside of the casing and the suction port into the evaporator side and the condenser side. This spot cooler is characterized by the following: A first embodiment of the spot cooler of the present invention will be described with reference to FIGS. 5 to 7. The basic configuration is the same as the conventional one. In the present invention, the suction port 9 at the lower center is connected to the partition plate 1 made of a heat insulating material.
2 from the top plate of the casing 2 and connect it to the condenser side suction port 13.
and an evaporator side suction port 14, and the inside of the casing is divided into a condensing side and an evaporator side. With this structure, even if the fan 8 is stopped during heat storage, the presence of the partition plate 1o prevents air from being sucked in from the cold air outlet 11 even if the fan 5 is running, and the heat loss of the evaporator 7 is extremely reduced. Therefore, heat storage efficiency improves. However, this embodiment also has the following slight drawback: The air in the evaporator side space 15 inside the casing is cooled and becomes heavy, so it accumulates in the lower part and flows out from the evaporator side suction port 14. , warm air is sucked in from the cold air outlet 11 by that amount.

するために、さらに第２の実施例を考えた。This is shown by the dotted line in FIG. Therefore, heat is applied to the heat storage material 23, and the amount of heat storage decreases. Therefore, in order to prevent this, a second embodiment was further devised.

ある。なお、仕切板１２ａ、１２ｂは断熱材で構成され
ることが好ましい。FIG. 8 shows a second embodiment. The basic configuration is the same as the conventional one, so the explanation will be omitted. In this embodiment, a partition plate 12a is arranged upward from the bottom plate on the evaporator side of the air inlet 13 at the lower center of the casing 2, and the upper part is open to form the evaporator side suction port 14, and the condenser side In this structure, a partition plate 12b is arranged downward from the top plate of the casing 2, and the lower part is open to form a condenser side suction port 13. Note that the partition plates 12a and 12b are preferably made of a heat insulating material.

少なくなり、蓄熱材２３の放熱が減少する。In this case, even if the fan 8 is stopped during heat storage, the partition plate 2a
, 12b prevents air from being drawn from the cold air outlet 11, improving heat storage efficiency. In addition, since the evaporator-side suction port 14 opens at the upper part of the evaporator-side space 21, low-temperature air accumulates in the lower part of the evaporator-side space 15, and natural convection occurs from the evaporator-side suction port 14 to the outside. The amount of air escaping becomes very small, and the heat radiation of the heat storage material 23 decreases.
本発明のスポットクーラは、蒸発器の蓄熱材へ蓄冷する
とき蒸発器周囲の空気が動かないために゛蓄熱効率が良
く、放熱ロスが少ないため、短時間で蓄熱が可能で、長
時間蓄熱量を維持できる利点がある。The spot cooler of the present invention has good heat storage efficiency and little heat radiation loss because the air around the evaporator does not move when storing cold in the heat storage material of the evaporator, so it can store heat in a short time and can store heat for a long time. It has the advantage of being able to maintain
