Description

本発明は冷蔵庫に関するものである。   The present invention relates to a refrigerator.

冷蔵庫に保存される野菜の鮮度維持を目的として、チルド室や野菜室の容器内に冷気が流入しにくい構造を設けた冷蔵庫が知られている。これは冷気が貯蔵物付近で対流すると貯蔵物の乾燥が進み、鮮度が落ちやすくなるためである。一方で、容器の密閉性を上げると、貯蔵物から発生する水蒸気が容器内に結露しやすくなる。結露が成長し、貯蔵物に滴下すると、貯蔵物を劣化させる可能性がある。特許文献1に記載の冷蔵庫では、「貯蔵物を収納する収納ケース、及び収納ケースの背面に向けて冷気を吹き出す吐出口を有する貯蔵室を備えた冷蔵庫において、貯蔵室は、収納ケース及び吐出口の間に防止部を有し、防止部は、吐出口から吹き出される冷気が収納ケースに直接当たることを防止するものであり、収納ケースは、防止部を挟んで、吐出口に対向する領域に孔を有する事を特徴とした冷蔵庫」を提供している。   For the purpose of maintaining the freshness of vegetables stored in the refrigerator, a refrigerator having a structure in which cold air does not easily flow into a container of a chilled room or a vegetable room is known. This is because when the cool air convects in the vicinity of the stored product, the stored product is dried and the freshness is likely to decrease. On the other hand, when the hermeticity of the container is increased, water vapor generated from the stored material is likely to be condensed in the container. If condensation grows and drip onto the stock, it can degrade the stock. In the refrigerator described in Patent Literature 1, in the refrigerator having a storage case for storing stored items and a storage chamber having a discharge port for blowing out cool air toward the back of the storage case, the storage chamber includes the storage case and the discharge port. The prevention part prevents the cold air blown from the discharge port from directly hitting the storage case, and the storage case is a region facing the discharge port with the prevention part interposed therebetween. The refrigerator is characterized by having a hole in it.

特開２０１５−１７８９４３号公報Japanese Patent Application Laid-Open No. 2015-178943

特許文献１に記載の冷蔵庫は，冷気の吐出口と収納ケース間に防止部を設けることで、直接冷気が収納ケースに当たることで収納ケース内と収納ケース内壁の温度差を減らし、結露しにくくする構造となっている。また、収納ケースには防止部を挟んで、吐出口に対向する領域に孔を設け、この孔から容器内で高まった水蒸気圧を防止部へ逃がし、防止部で結露させることで収納ケース内での結露を防いでいる。   The refrigerator described in Patent Document 1 is provided with a prevention portion between the cool air discharge port and the storage case, so that the cool air directly hits the storage case, thereby reducing the temperature difference between the storage case and the inner wall of the storage case, thereby preventing condensation. It has a structure. In addition, the storage case is provided with a hole in the area facing the discharge port with the prevention part in between, and the water vapor pressure increased in the container from the hole is released to the prevention part, and the prevention part condenses in the storage case. Prevents condensation.

しかしながら、特許文献1に記載の冷蔵庫は、防止部に結露させた結露水の処理について十分に検討がなされていない。実施例の1つとして、防止部に付着した結露水は、水受部に溜められる構造を提案しているが、水受部に溜められる結露水の量には限界を有する。つまり、特許文献１の実施例のような構造にすると、結露水の蒸発量よりも発生する結露量が勝っていた場合、水受部外に水が溢れ、貯蔵室外や収納ケースへ流入する恐れがある。   However, the refrigerator described in Patent Document 1 has not been sufficiently studied for the treatment of condensed water condensed on the prevention unit. As one of the embodiments, a structure is proposed in which the dew condensation water adhering to the prevention part is stored in the water receiving part, but the amount of the dew condensation water stored in the water receiving part is limited. That is, with the structure as in the embodiment of Patent Document 1, if the amount of condensation generated exceeds the amount of condensation water evaporation, there is a risk that water overflows outside the water receiving portion and flows into the storage chamber or the storage case. There is.

また、防止部は収納ケースとの断熱の役割を担うため、収納ケースと距離をとる必要があるが、その分食品収納スペースが減少してしまう。水受部を設けるとさらにその分食品収納スペースが減少する。   Moreover, since the prevention part plays a role of heat insulation with the storage case, it is necessary to keep a distance from the storage case, but the food storage space is reduced accordingly. When the water receiving portion is provided, the food storage space is further reduced accordingly.

以上のように、特許文献1に記載の冷蔵庫では、結露水の処理及び食品収納スペースの減少については十分に考慮されていない。   As described above, the refrigerator described in Patent Document 1 does not sufficiently consider the treatment of condensed water and the reduction of food storage space.

本発明は、以上のような問題点に鑑みてなされたものであり、食品収納スペースを広く確保しつつ、収納ケース内の結露を抑制して食品の鮮度保持性能を高めた冷蔵庫を得ることを目的とする。   The present invention has been made in view of the above problems, and is to obtain a refrigerator that has improved food freshness retention performance by suppressing condensation in the storage case while ensuring a wide food storage space. Objective.

上記課題を解決するために，例えば特許請求項の範囲に記載の構成を採用する。本願は上記課題を解決する手段を複数含んでいるが，その一例を挙げるならば，冷蔵温度帯室と、前記冷蔵温度帯室に収納される収納容器と、前記収納容器の上面を覆う蓋体と、冷却器と前記冷蔵温度帯室内の空気を強制対流させる送風ファンと、を備える冷蔵庫において、前記蓋体は、開口部を有し、前記開口部は、前記送風ファンによる冷気循環経路の途中に位置する。   In order to solve the above problems, for example, the configuration described in the scope of claims is adopted. The present application includes a plurality of means for solving the above-described problems. For example, a refrigeration temperature zone chamber, a storage container stored in the refrigeration temperature zone chamber, and a lid that covers the upper surface of the storage container And a cooling fan and a blower fan that forcibly convects the air in the refrigerated temperature zone, wherein the lid has an opening, and the opening is in the middle of a cold air circulation path by the blower fan Located in.

本発明によれば，食品収納スペースを広く確保しつつ、収納ケース内の結露を抑制して食品の鮮度保持性能を高めた冷蔵庫を得ることができる。   ADVANTAGE OF THE INVENTION According to this invention, the refrigerator which suppressed the dew condensation in a storage case and improved the freshness maintenance performance of a foodstuff can be obtained, ensuring a food storage space widely.

以下、本発明の実施形態に係る冷蔵庫について、図面を参照しながら詳細に説明する。また、以下では、三つの空間に区切られる３ドアタイプの冷蔵庫を例に挙げて説明するが、二つの空間に区切られるタイプの冷蔵庫に適用してもよく、四つ以上の空間に仕切られるタイプの冷蔵庫に適用してもよい。   Hereinafter, a refrigerator according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following, a three-door type refrigerator divided into three spaces will be described as an example. However, it may be applied to a refrigerator divided into two spaces, and is divided into four or more spaces. You may apply to the refrigerator.

図１は、冷蔵庫の正面図である。図１に示すように、冷蔵庫１００Ａは、冷蔵庫本体１と、その前面に設けられた複数の扉５，６，７を備えて構成されている。扉５は、上段に位置し、回動式のものである。扉６は、中段に位置し、引き出し式のものである。扉７は、下段に位置し、引き出し式のものである。   FIG. 1 is a front view of the refrigerator. As shown in FIG. 1, the refrigerator 100 </ b> A includes a refrigerator main body 1 and a plurality of doors 5, 6, 7 provided on the front surface thereof. The door 5 is located in the upper stage and is a rotary type. The door 6 is located in the middle stage and is a pull-out type. The door 7 is located at the lower stage and is a pull-out type.

図２は、図１の冷蔵庫の縦断面図である。なお、図２は、概略的に図示している。図２に示すように、冷蔵庫本体１は、例えば、鋼板製の外箱８と、樹脂製の内箱９と、外箱８と内箱９の間に充填された発泡断熱材１０とから構成されており、上から順に上部冷蔵温度帯室である冷蔵室２、下部冷蔵温度帯室である野菜室３、冷凍温度帯室である冷凍室４が、それぞれ区画して構成されている。なお、断熱性能の向上を要する場合は、発泡断熱材１０と共に真空断熱材（図示せず）を併設する。   FIG. 2 is a longitudinal sectional view of the refrigerator of FIG. Note that FIG. 2 is schematically illustrated. As shown in FIG. 2, the refrigerator main body 1 includes, for example, a steel plate outer box 8, a resin inner box 9, and a foam heat insulating material 10 filled between the outer box 8 and the inner box 9. The refrigeration chamber 2 that is the upper refrigeration temperature zone chamber, the vegetable chamber 3 that is the lower refrigeration temperature zone chamber, and the freezing chamber 4 that is the refrigeration temperature zone chamber are divided and configured in order from the top. In addition, when the heat insulation performance needs to be improved, a vacuum heat insulating material (not shown) is provided together with the foam heat insulating material 10.

例えば、冷蔵室２および野菜室３の設定温度は、０℃〜５．０℃の温度帯に設定され、冷凍室４は−１８℃〜−２０℃の温度帯に設定されている。このため、野菜室３と冷凍室４との間は断熱仕切り壁１１によって断熱区画されている。また、冷蔵室２と野菜室３との間は、設定温度帯が近いため、断熱材を含まない仕切り壁１２により区画されている。また、仕切り壁１２には、冷蔵室２から野菜室３に冷気を吐出させる吐出口１２ａが形成されている。   For example, the set temperature of the refrigerator compartment 2 and the vegetable compartment 3 is set to a temperature range of 0 ° C. to 5.0 ° C., and the freezer compartment 4 is set to a temperature range of −18 ° C. to −20 ° C. For this reason, the vegetable compartment 3 and the freezer compartment 4 are heat-insulated by the heat-insulating partition wall 11. Moreover, since the set temperature range is close between the refrigerator compartment 2 and the vegetable compartment 3, it is divided by the partition wall 12 which does not contain a heat insulating material. Further, the partition wall 12 is formed with a discharge port 12a for discharging cold air from the refrigerator compartment 2 to the vegetable compartment 3.

冷蔵庫本体１の前面には、前記したように、冷蔵室２、野菜室３、冷凍室４の前面開口を閉塞するため、それぞれ、扉５，６，７が前面開口縁部に対してパッキング（不図示）を介して設けられている。扉５は、冷蔵室２の前面開口を閉塞し、扉６は、野菜室３の開口を閉塞し、扉７は冷凍室４の前面開口を閉塞する。   On the front surface of the refrigerator body 1, as described above, the front openings of the refrigerator compartment 2, the vegetable compartment 3, and the freezer compartment 4 are closed. (Not shown). The door 5 closes the front opening of the refrigerator compartment 2, the door 6 closes the opening of the vegetable compartment 3, and the door 7 closes the front opening of the freezer compartment 4.

また、引き出し式の扉６は、野菜室３内に設けられた上段容器４１および下段容器４２を伴って引き出す構造となっている。また、引き出し式の扉７も、冷凍室４内に設けられた収納容器５０を伴って引き出す構造となっている。   The drawer-type door 6 has a structure in which it is pulled out with an upper container 41 and a lower container 42 provided in the vegetable compartment 3. In addition, the drawer-type door 7 is also structured to be pulled out with a storage container 50 provided in the freezer compartment 4.

また、冷蔵庫本体１は、冷凍サイクルを搭載している。この冷凍サイクルは、圧縮機１３、凝縮器（図示せず）、キャピラリチューブ（図示せず）、冷却器１４、および、これらを順に接続する環状の冷媒配管（図示せず）によって構成されている。また、冷却器１４は、野菜室３の背面に設けられた冷却器室１５内に設置されている。この冷却器室１５における冷却器１４の上方には、冷却器１４と野菜室３内の空気を強制対流させる送風ファン１６が設置されている。また、冷蔵室２の背面には、冷蔵室背面パネル１８が設けられている。冷蔵室背面パネル１８には、送風ファン１６から供給された冷気を通す冷気通路１７が設けられている。また、冷蔵室背面パネル１８には、冷気通路１７を通した冷気を冷蔵室２内に吹き出す冷気吹出し孔１８ａが上下方向に間隔を空けて複数箇所に形成されている。   The refrigerator main body 1 is equipped with a refrigeration cycle. This refrigeration cycle includes a compressor 13, a condenser (not shown), a capillary tube (not shown), a cooler 14, and an annular refrigerant pipe (not shown) that connects them in order. . The cooler 14 is installed in a cooler chamber 15 provided on the back of the vegetable chamber 3. Above the cooler 14 in the cooler chamber 15, a blower fan 16 that forcibly convects the air in the cooler 14 and the vegetable chamber 3 is installed. A refrigerating room back panel 18 is provided on the back of the refrigerating room 2. The refrigerator compartment back panel 18 is provided with a cool air passage 17 through which the cool air supplied from the blower fan 16 passes. Further, in the refrigerator compartment back panel 18, cold air outlet holes 18 a through which the cold air passing through the cold air passage 17 is blown into the refrigerator compartment 2 are formed at a plurality of positions at intervals in the vertical direction.

冷蔵庫１００Ａでは、冷却器１４によって冷却され、且つ、冷気量制御ダンパー（図示せず）を介した冷気は、冷気通路１７、冷気吹出し孔１８ａから冷蔵室２に供給され、冷蔵室２の貯蔵空間を設定温度帯に冷却する。そして、冷蔵室２内の冷気は、吐出口１２ａを通って野菜室３に供給され、野菜室３の貯蔵空間を設定温度帯に冷却する。このように、野菜室３を冷却する冷気は冷蔵室２を通過した後の冷気となる。そして、野菜室３内の冷気は、上段容器４１および下段容器４２上面を覆う蓋板（蓋体）４３Ａ上面から上段容器４１および下段容器４２背面側を流れ、野菜室３の背面（段容器４１および下段容器４２後方）に設けられた冷気の戻り口（排出口）３ａを介して、冷却器室１５に戻るようになっている。なお、冷凍室４は、図示しない冷却流路を通って冷気が循環するように構成されている。   In the refrigerator 100A, the cool air cooled by the cooler 14 and supplied through the cool air amount control damper (not shown) is supplied to the refrigerating chamber 2 from the cool air passage 17 and the cool air outlet hole 18a. Is cooled to the set temperature range. And the cold air in the refrigerator compartment 2 is supplied to the vegetable compartment 3 through the discharge outlet 12a, and cools the storage space of the vegetable compartment 3 to a preset temperature range. Thus, the cool air that cools the vegetable compartment 3 becomes the cool air after passing through the refrigerator compartment 2. The cold air in the vegetable compartment 3 flows from the upper surface of the cover plate (lid body) 43A covering the upper surfaces of the upper container 41 and the lower container 42 to the rear side of the upper container 41 and the lower container 42, and the rear surface of the vegetable chamber 3 (the container 41). And it returns to the cooler chamber 15 via the return port (discharge port) 3a of the cold air provided in the rear of the lower container 42). In addition, the freezer compartment 4 is comprised so that cold air may circulate through the cooling flow path which is not shown in figure.

また、冷蔵室２内には透明な樹脂板またはガラス板で構成される複数段の棚１９，２０，２１，２２が設置されている。また、最下段の棚２２の下側には、引き出し式の収納トレイ２３が設けられている。なお、収納トレイ２３に替えて、食品の鮮度保持および長期保存するための密閉空間を構成する減圧貯蔵室を有する引き出し式の収納トレイを備えていてもよい。   A plurality of shelves 19, 20, 21, and 22 made of a transparent resin plate or glass plate are installed in the refrigerator compartment 2. A drawer-type storage tray 23 is provided below the lowest shelf 22. In addition, it may replace with the storage tray 23 and may be provided with the drawer-type storage tray which has the pressure-reduction storage chamber which comprises the sealed space for the freshness preservation | save of foodstuffs, and long-term preservation | save.

図３は、収納容器と蓋体の分解斜視図である。図３に示すように、野菜室３は、上段容器４１および下段容器４２によって構成されている。また、上段容器４１および下段容器４２の上部開口は、蓋板（蓋体）４３Ａによって略密閉状態に覆われる。野菜室３では、上段容器４１および下段容器４２が前後方向に引出自在に収納されている。蓋板４３Ａは、上段容器４１および下段容器４２の上部開口を覆うものであり、冷蔵庫本体１の仕切り壁１２に固定されている。よって、上段容器４１および下段容器４２が引き出されたとしても、蓋板４３Ａの位置は変化しない。   FIG. 3 is an exploded perspective view of the storage container and the lid. As shown in FIG. 3, the vegetable compartment 3 is composed of an upper container 41 and a lower container 42. The upper openings of the upper container 41 and the lower container 42 are covered in a substantially sealed state by a lid plate (lid body) 43A. In the vegetable compartment 3, the upper container 41 and the lower container 42 are accommodated so that they can be pulled out in the front-rear direction. The cover plate 43 </ b> A covers the upper openings of the upper container 41 and the lower container 42, and is fixed to the partition wall 12 of the refrigerator main body 1. Therefore, even if the upper container 41 and the lower container 42 are pulled out, the position of the lid plate 43A does not change.

上段容器４１は、上面が開放した略四角箱形状かつ扁平形状を呈し、前板４１ａ、側板４１ｂ，４１ｂ、背板４１ｃおよび底面４１ｄによって樹脂成形されている。また、上段容器４１の左右の側板４１ｂの外面には、前後方向に延在するフランジ４１ｂ１（右側のみ図示）が形成されている。このフランジ４１ｂ１が下段容器４２の側板４２ｂの上縁部に支持されるとともに、上段容器４１が前後方向にスライド自在に構成されている。なお、野菜室３を構成する左右の側壁（側面）には、下段容器４２を引き出したときにフランジ４１ｂ１を支持するためのスライドレール（図示せず）が設けられている。   The upper container 41 has a substantially square box shape and a flat shape with an open upper surface, and is resin-molded by a front plate 41a, side plates 41b and 41b, a back plate 41c, and a bottom surface 41d. Further, on the outer surface of the left and right side plates 41b of the upper container 41, a flange 41b1 (only the right side is shown) extending in the front-rear direction is formed. The flange 41b1 is supported on the upper edge of the side plate 42b of the lower container 42, and the upper container 41 is configured to be slidable in the front-rear direction. In addition, the left and right side walls (side surfaces) constituting the vegetable compartment 3 are provided with slide rails (not shown) for supporting the flange 41b1 when the lower container 42 is pulled out.

下段容器４２は、上面が開放した略四角箱形状を呈し、前板４２ａ、側板４２ｂ，４２ｂ、背板４２ｃおよび底板４２ｄによって樹脂成形されている。背板４２ｃは、前板４２ａと側板４２ｂ，４２ｂよりも底板４２ｄからの高さが低く形成されている。また、下段容器４２は、前板４２ａの前部と、側板４２ｂ，４２ｂの前部とが、側板４２ｂの後部よりも底板４２ｄからの高さが一段高く形成されている。   The lower container 42 has a substantially square box shape with an open upper surface, and is resin-molded by a front plate 42a, side plates 42b and 42b, a back plate 42c, and a bottom plate 42d. The back plate 42c is formed with a lower height from the bottom plate 42d than the front plate 42a and the side plates 42b and 42b. Further, in the lower container 42, the front part of the front plate 42a and the front parts of the side plates 42b and 42b are formed so that the height from the bottom plate 42d is one step higher than the rear part of the side plate 42b.

蓋板４３Ａは、合成樹脂製のものであり、上方からの平面視において略矩形状に形成されている。蓋板４３Ａの上面には、蓋板４３Ａを仕切り壁１２に取り付けるためのフック４３ａ，４３ｂが上方に向けて突設されている。フック４３ｂは、蓋板４３Ａの手前側で左右両側に位置している。また、フック４３ａは、蓋板４３Ａの後方に位置している。このような位置にフック４３ａ，４３ｂを配置することにより、必要最小限の数で蓋板４３Ａを安定して仕切り壁１２に固定することができる。なお、図示省略するが、仕切り壁１２には、フック４３ａ，４３ｂを引っ掛けるための引掛部（爪や孔など）が形成されている。   The lid plate 43A is made of a synthetic resin and is formed in a substantially rectangular shape in plan view from above. On the upper surface of the lid plate 43A, hooks 43a and 43b for attaching the lid plate 43A to the partition wall 12 are provided so as to project upward. The hooks 43b are located on the left and right sides on the front side of the lid plate 43A. The hook 43a is located behind the lid plate 43A. By arranging the hooks 43a, 43b at such positions, the cover plate 43A can be stably fixed to the partition wall 12 with the minimum necessary number. Although not shown in the figure, the partition wall 12 is formed with hooks (claws, holes, etc.) for hooking the hooks 43a, 43b.

蓋板４３Ａがあることで、吐出口１２ａから吐出される冷気によって生じる上段容器４１および下段容器４２に保存された野菜等表面の対流量を減少させ、野菜の乾燥等を抑制することができる。   By having the cover plate 43A, it is possible to reduce the counter flow rate of the surface of the vegetables and the like stored in the upper container 41 and the lower container 42 generated by the cold air discharged from the discharge port 12a, and to suppress drying of the vegetables and the like.

また、蓋板４３Ａの後方、具体的には吐出口１２ａより後方に、開口部４３ｃが設けられている。この開口部４３ｃは、上段容器４１の上から見て前板４１ａ、側板４１ｂ，４１ｂ、背板４１ｃより内側に位置する。ここで、上段容器４１や下段容器４２の内部は、これらの容器内に保存される野菜等から発生する水蒸気が、蓋板４３Ａで（密閉度が向上し）一定程度閉じ込められることによって、湿度が高くなっている。この蓋板４３Ａに設けられた開口部４３ｃは、上段容器４１や下段容器４２の内部の余分な水分を含む空気を、外部へ放出するためのものであり、左右方向に長くするなど所定の大きさを有している。   An opening 43c is provided behind the lid plate 43A, specifically, behind the discharge port 12a. The opening 43c is located inside the front plate 41a, the side plates 41b and 41b, and the back plate 41c when viewed from above the upper container 41. Here, in the upper container 41 and the lower container 42, the moisture generated by the vegetables stored in these containers is confined to a certain extent by the lid plate 43A (the degree of sealing is improved), thereby reducing the humidity. It is high. The opening 43c provided in the lid plate 43A is for releasing air containing excess moisture inside the upper container 41 and the lower container 42 to the outside, and has a predetermined size such as being elongated in the left-right direction. Have

開口部４３ｃは、吐出口１２ａから冷気の戻り口（排出口）３ａ間に流れる冷気循環流路の途中に位置する。つまり、開口部４３ｃ上には冷気が流れる。開口部４３ｃより吐出される水蒸気圧の高い空気は、この冷気の流れによって戻り口（排出口）３ａへと流れ、冷却器１４へと戻り、霜となって冷却器１４に付着する。冷却器１４に付着した霜は冷却器１４下部に設置された除霜ヒータ(図示なし)によって圧縮機１３上に設置された蒸発皿（図示なし）へ排水される。ゆえに、上段容器４１および下段容器４２内に保存された野菜等から発生する水蒸気が上段容器４１や下段容器４２には結露せず、冷蔵庫外に排出されるため、結露水が冷蔵庫内に溜まることによる弊害は発生しない。同時に、冷蔵庫内に結露水を溜める水受部を設ける必要がないため、食品収納スペース等の減少も防ぐことができる。   The opening 43c is located in the middle of the cool air circulation channel that flows between the discharge port 12a and the cool air return port (discharge port) 3a. That is, cold air flows over the opening 43c. Air having a high water vapor pressure discharged from the opening 43c flows to the return port (discharge port) 3a by the flow of the cold air, returns to the cooler 14, and becomes frost and adheres to the cooler 14. The frost adhering to the cooler 14 is drained to an evaporating dish (not shown) installed on the compressor 13 by a defrost heater (not shown) installed at the lower part of the cooler 14. Therefore, water vapor generated from vegetables stored in the upper container 41 and the lower container 42 is not condensed in the upper container 41 and the lower container 42 and is discharged outside the refrigerator, so that the condensed water accumulates in the refrigerator. No negative effects will occur. At the same time, since it is not necessary to provide a water receiving part for storing condensed water in the refrigerator, it is possible to prevent a decrease in food storage space and the like.

また、上段容器４１の後方傾斜壁面や下段容器４２の後方傾斜壁面は、特に結露し易い部分であるため、開口部４３ｃを、各容器の前後中央よりも後方、具体的には開口部４３ｃの鉛直投影がこれら後方傾斜壁面と重なるような位置に、設けるのが望ましい。なお、上段容器４１の前方上端と蓋板４３Ａとの間には隙間を有しており、下段容器４２と連通されているため、下段容器４２内の余分な水分を含む空気も、開口部４３ｃを介して外部へ放出される。   In addition, since the rear inclined wall surface of the upper container 41 and the rear inclined wall surface of the lower container 42 are portions that are particularly susceptible to condensation, the opening 43c is located behind the front and rear centers of each container, specifically, the opening 43c. It is desirable to provide at a position where the vertical projection overlaps these rear inclined wall surfaces. In addition, since there is a gap between the front upper end of the upper container 41 and the lid plate 43A and communicates with the lower container 42, air containing excess moisture in the lower container 42 is also opened by the opening 43c. It is discharged to the outside through.
