  A showcase used in a store such as a convenience store is required to be clean and make it easy for customers to see the products displayed in the showcase. Furthermore, a showcase for displaying cooked items is desired to hold the cooked items in a delicious state. It is desirable that an article having a “crisp” texture can maintain a more “crisp” state, and an article having a “moist” texture can maintain a more “moist” state. In general, it is desirable to maintain a product having a moist texture in a high humidity atmosphere. However, if an attempt is made to maintain a humid atmosphere, condensation tends to occur on the inner surface of the showcase. In particular, dew condensation tends to occur in a showcase installed in an environment exposed to cold air from an air conditioning system.

  Patent Document 1 describes a storage device in which a dry chamber and a wet chamber are partitioned and provided side by side. In order to make it easier to see the products provided in the showcase, an exterior panel and a partition panel are provided. It is preferable that the distance is as close as possible. However, if the space between the exterior panel and the partition panel is narrowed, the temperature drop due to cold air that has been conditioned, for example, reaches the exterior panel or the interior partition panel, and depending on the conditions, condensation may form on the exterior panel or partition panel. May occur.

  One aspect of the present invention includes a first storage chamber that includes a light-transmitting first wall and forms a first closed space for displaying merchandise, and is stored in the first storage chamber. A second storage chamber forming a second closed space for displaying goods, the second storage chamber having a translucent second wall at a position facing the first wall And a hot air supply unit for circulating hot air of low humidity in the first closed space, and the hot air circulates between the first wall and the second wall. It is a showcase device that is part of the route for

  In this showcase device, the second storage chamber is provided inside the first closed space of the first storage chamber, and the second closed space is provided. Then, low-humidity hot air is circulated in the first closed space. The second closed space is heated by the warm air circulating in the first closed space, but the humidity depends on the goods displayed in the second closed space. Can do. When displaying cooked items, the atmosphere often becomes humid due to moisture released from the cooked items. Therefore, the second closed space is a space suitable for displaying products that are desired to be stored at high temperature and high humidity.

  On the other hand, the first closed space circulates low-humidity hot air. When a cooked item is displayed, moisture released from the cooked item is dehumidified, so that a space suitable for displaying a product that is desired to be stored at high temperature and low humidity is provided. Furthermore, since the first closed space is a low-humidity atmosphere, there is little possibility that condensation will occur even if the temperature is suddenly lowered due to exposure to cold air. Although there is a possibility that the second closed space has a high humidity atmosphere, since the second closed space is provided in the first closed space having a high temperature and low humidity, there is little possibility of condensation.

  Furthermore, in this showcase device, by making the low-humidity hot air circulate between the light-transmitting first wall and the light-transmitting second wall part of these, Forcibly ventilate between the walls with warm air of low humidity. Therefore, even if the space between the light-transmitting first wall and the second wall is narrowed, moisture hardly accumulates and condensation does not easily occur. Further, even if the space between the light-transmitting first wall and the second wall is narrowed, it is possible to prevent the temperature drop due to the outside, for example, the cold air of the air conditioning, from reaching the second wall or the inside thereof, Condensation can be prevented from occurring in the second storage chamber. For this reason, it is possible to bring the first wall and the second wall that are translucent, for example, transparent, and the second wall is closed from the outside of the first wall to the inside of the second wall. It is possible to provide a showcase device that makes it easy to see the products displayed in the space.

  Another aspect of the present invention includes a first storage chamber that includes a first light-transmitting wall and forms a first closed space for displaying merchandise, and is stored in the first storage chamber. A second storage chamber forming a second closed space for displaying merchandise, the second storage chamber having a translucent second wall at a position facing the first wall And a warm air supply unit for circulating the heated air in the first closed space, and the space between the first wall and the second wall is heated. It is a showcase device that is part of a path for air to circulate.

  In this showcase device, the heated air circulates in the first closed space, and the conditions in the first closed space are controlled. On the other hand, the second closed space is heated by the heated air circulating in the first closed space, but the humidity is displayed in the second closed space. Depends on. Therefore, in this showcase device, by controlling the conditions of the outer first closed space, conditions suitable for the goods stored in the space and the outside world, that is, in the store where the showcase device is installed It can be made to correspond to the conditions. Since the inner second closed space is covered by the first closed space, priority is given to conditions suitable for the goods stored in the second closed space rather than to respond to external conditions. Can be made.

  Therefore, in this showcase device, by controlling the conditions of the first outer space, the conditions suitable for the goods stored in the space and the outside world, that is, the conditions in the store where the showcase device is installed are set. Can be matched. Since the inner second space is covered by the first space, it is possible to prioritize conditions suitable for products stored in the second space rather than dealing with external conditions.

  Further, by circulating the heated air between the light-transmitting first wall and the light-transmitting second wall, the light-transmitting first wall and the second wall are circulated. Even if the interval is narrowed, accumulation of moisture can be suppressed. For this reason, it is possible to bring the first wall and the second wall that are translucent, for example, transparent, and the second wall is closed from the outside of the first wall to the inside of the second wall. It is possible to provide a showcase device that makes it easy to see the products displayed in the space.

  In these showcase devices, a portion between the first wall and the second wall may be a part of a path for blowing out hot air or warmed air from the hot air supply unit. In these showcase devices, the space between the first wall and the second wall may be part of a path for collecting the hot air to the hot air supply unit.

  By narrowing the gap between the first wall and the second wall, the pressure loss increases when air passes through the path between the first wall and the second wall. When the path passing between the first and second walls is the hot air collecting side, the air volume and the air speed of the hot air supplied from the hot air supply unit to the first closed space are maintained. Cheap. Further, the fan efficiency is higher when the differential pressure is generated on the suction side of the fan included in the hot air supply unit.

  Further, in this showcase device, the first storage chamber includes a first door for opening and closing the first storage chamber, and the second storage chamber is located at a position facing the first door. A second door for opening and closing the second storage chamber may be provided, and a portion between the first door and the second door may be a part of a path for circulating hot air.

  That is, according to still another aspect of the present invention, a first storage chamber that forms a first closed space for displaying merchandise and a first storage chamber that is stored in the first storage chamber and displays merchandise. A second storage chamber that forms two closed spaces, and a hot air supply unit that circulates low-humidity hot air in the first closed space, A first door for opening and closing the first storage chamber, and the second storage chamber is a second door for opening and closing the second storage chamber at a position facing the first door. The showcase device is a part of a path for circulating the warm air between the first door and the second door.

  According to still another aspect of the present invention, there is provided a first storage chamber that forms a first closed space for displaying a product, and a second storage for displaying the product that is stored in the first storage chamber. A second storage chamber that forms a closed space; and a hot air supply unit for circulating warmed air in the first closed space. A first door for opening and closing the first storage chamber is provided, and the second storage chamber is provided with a second door for opening and closing the second storage chamber at a position facing the first door. In the showcase device, the space between the first door and the second door is part of a path for circulating the heated air.

  It is usually difficult to ensure the sealing of the door portion, and there is a high possibility that leakage will occur for some reason. In these showcase devices, the possibility of leakage from the first storage chamber on the outside world is low-humidity warm air or air that has been heated to lower the relative humidity. Is unlikely to occur. Even if high-humidity air leaks from the second storage chamber, the leaking destination is the first closed space with a low-humidity and high-temperature atmosphere, and there is little possibility of condensation.

  In addition, the second closed space is a hot and humid atmosphere, and when the second door is opened to display or take out goods in the second closed space, the humid air leaks out. Even so, the leakage destination is the first closed space with a low-humidity and high-temperature atmosphere. When the second door is opened, the first door is also opened. During this time, forcibly circulating low-humidity hot air can prevent high-temperature and high-humidity air from leaking to the outside. That is, as described above, even if the second closed space becomes hot and humid, the showcase device can prevent moisture from leaking out and dewing.

  The first door and the second door may be hinged doors (doors that can be opened and closed by hinges) or sliding doors (sliding doors). By using sliding doors (sliding doors) to open and close these storage chambers, the structure of the door is simplified, and almost no space is required to open and close the doors. In particular, by using the door of the first storage chamber located outside as a sliding door, the space required for opening and closing the door can be omitted. Although it is difficult to secure the sealing property of the sliding door, in this showcase device, the first storage chamber is basically lower in humidity than the second storage chamber, so that air leaks to the outside. Condensation is unlikely to occur even when it is put out. In addition, the second storage chamber has a higher humidity than the first storage chamber, but the air leakage destination is the first storage chamber with a low humidity. Therefore, in these showcase devices, even if the air in the first and second storage chambers leaks, the configuration is such that condensation does not easily occur, and leakage is allowed. Furthermore, in the first storage room, on the contrary, fresh air can be injected by allowing a certain amount of air to leak by using a sliding door. Therefore, low-humidity hot air is supplied and the interior is dried. It is suitable for making the atmosphere.

  In these showcase devices, the arrangement of the second storage chamber is basically free as long as it is within the first closed space. On the other hand, the second storage chamber is preferably disposed on the bottom wall of the first storage chamber, and the hot air supply unit is preferably disposed below the bottom wall of the first storage chamber. It is an example of arrangement | positioning which the support of a 2nd storage chamber is easy and a warm air supply unit is not conspicuous.

  In these showcase devices, when the second storage chamber is arranged on the bottom wall of the first storage chamber, the hot air supply unit sends the hot air to the bottom wall of the second storage chamber. It is preferable to include a path for supplying the first storage chamber after contacting the first storage chamber. By doing in this way, the 2nd storage room can be warmed efficiently by the low humidity warm air which circulates through the 1st closed space, and the heat transfer via a bottom wall. When the second storage chamber is arranged on the bottom wall of the first storage chamber, the bottom wall of the second storage chamber may be separate from the bottom wall of the first storage chamber. However, the bottom wall of the first storage chamber may also serve as the bottom wall of the second storage chamber.

  Furthermore, the other aspect of this invention is a display sales unit which has these showcase apparatuses and the storage unit arrange | positioned under the warm air supply unit of a showcase apparatus. The storage unit includes a cool box and a cooling unit for cooling the inside of the cool box. The showcase device needs to heat fresh air commensurate with the warm air leaking from the first door or the like and supply it to the first storage chamber. Therefore, by providing the display sales unit with a communication path for supplying at least a part of the high-temperature exhaust of the cooling unit as the fresh air of the hot air supply unit, it is possible to reduce the heat load for heating the fresh air.

  In the showcase device included in the present invention, the first storage chamber includes a first door for opening and closing the first storage chamber, and the second storage chamber is in the direction of the first door. And may be opened and closed by the first door. In this showcase device, the first and second storage chambers can be opened by one operation of opening the first door. Therefore, it is easy to take out not only the products stored in the first storage chamber but also the products stored in the second storage chamber.

  One mode for opening and closing the first and second storage chambers with the first door is that the first storage chamber is closed by the first door at the open end of the second storage chamber. Sometimes, providing a seal member in contact with the first door. A state in which the first door is closed when the first and second storage chambers are opened and closed by the common first door by providing a sealing member at the open end of the second storage chamber. In this case, it is possible to prevent the humid air from the second storage chamber from leaking out to the first storage chamber and further to the outside.

  As described above, the first door may be a hinged door (a door that can be opened and closed by a hinge) or a sliding door (sliding door). When the first and second storage chambers are opened and closed with a common first door, it is preferably a swing door. In the case of a hinged door, the seal member of the second storage chamber does not contact the first door except when it is closed, so that it is difficult to open and close. In the closed state, the seal member is placed on the inner surface of the first door. Seal in contact. Therefore, it is easy to seal the second storage chamber with the first door formed of a transparent or translucent plate such as acrylic or glass.

  In this showcase device, the first storage chamber includes a first side wall facing in a direction different from the first wall, and the second storage chamber is located at a position facing the first side wall. A side wall may be provided, and between the first side wall and the second side wall may be a part of a path for circulating hot air or heated air. By doing so, the warm air from the warm air supply unit passes between the first wall and the second wall and between the first side wall and the second side wall. Warming the second storage chamber as if the hot air from the supply unit passes between the first wall and the second wall and between the first door and the second door. Can do. Furthermore, by forcibly ventilating between these side walls with warm air, the occurrence of condensation can be prevented. Furthermore, even if the space between the light transmitting first and second side walls is narrowed, it is possible to prevent the temperature drop due to cold air from the outside, for example, air conditioning, from reaching the second side wall or the inside thereof. Condensation can be prevented from occurring in the room. For this reason, it is possible to make the first and second side walls transparent, for example, transparent, and the second closed side inside the second side wall from the outside of the first and second side walls. It is easy to see the products displayed in the space, and a compact showcase device can be provided.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a showcase device according to a first embodiment of the present invention. FIG. 2 is a rear view of the showcase device of FIG. FIG. 3 is a longitudinal sectional view showing a schematic configuration of the showcase device of FIG.

  Moisture leaked from the portion that opens and closes for displaying and taking out products in the showcase easily forms condensation near the portion that opens and closes. Furthermore, moisture that leaks out when the product is taken out from a place with a high humidity atmosphere easily condenses. Accordingly, it is not easy to hold the product in a hot and humid atmosphere and prevent condensation due to the influence of the cold air from the air conditioning or moisture leakage from the opening / closing part. One of the means to prevent moisture from leaking from the opening and closing parts in the store space that is air-conditioned and cool to the inside of the showcase is to use a door with a highly airtight swing type or double door opening type. Is to adopt. However, a door with high sealing performance has a complicated structure, and in many cases, it is necessary to secure a wide space for opening and closing the door. In addition, when the product is opened and closed to put in and out the product, high-humidity air leaks to the outside regardless of the sealing property. The showcase apparatus shown using FIGS. 1 to 3 is an example of an embodiment that aims to provide a showcase apparatus that is unlikely to cause condensation even when a sliding door is used.

  The showcase device 1a of this example is a device or unit suitable for displaying and selling cooked food as a product in a store such as a convenience store. The showcase device 1a for display sales has both a function as a showcase for displaying products and a function as a device for keeping products warm (stored).

  The housing 2 of the showcase device 1a is a box shape that is long in the vertical direction as a whole, and is disposed between the upper wall 3 facing the ceiling of the store and the lower wall 4 facing the floor when installed in the store. The first partition wall 5 and the second partition wall 6 are provided. In addition, the code | symbol L in FIG. 3 is an illumination means. The showcase device 1a is roughly provided with four functional sections A1, A2, A3 and A4. The space between the upper wall 3 and the first partition wall 5 is a section A1 of the display chamber 10, and the cooked food can be displayed while being kept warm. Below the display chamber 10 and between the first partition wall 5 and the second partition wall 6 is a section A2 of the hot air supply unit 20 for supplying hot air to the display chamber 10. Below the section A2 and between the second partition wall 6 and the lower wall 4 is the section A3 of the storage unit 30, in which the refrigerator 31 and the cooling unit 35 are stored. On the 2nd partition 6, the division A4 of the back of the warm air supply unit 20 is the cooking space 50, and the upper surface of the 2nd partition 6 of the part becomes the working table 51 which can be used as a cooking table etc. On the working table 51, a cooking utensil 90 such as a hot plate can be placed, and other utensils necessary for processing and cooking products can be mounted. The height of the working table 51 is preferably close to the clerk's waist so that the clerk can reach out without difficulty.

  The display room 10 can display cooked foods. The first storage room 11 of the display room 10 displays products (products that are preferably stored at high temperature and low humidity) that have a “crisp” texture such as American dogs among the cooked products. For forming a first closed space S1. The first space S1 is adjusted to a humidity of about 20% to 30% and a temperature of about 65 ° C. to 70 ° C. by the warm air of low humidity that has been heated from the warm air supply unit 20 to reduce the relative humidity. ing.

  A first storage chamber (hereinafter also referred to as a drying chamber) 11 is a translucent first front wall 61 that also serves as an upper front wall of the housing 2, and for opening and closing the first storage chamber 11. And a translucent first door 71. The first front wall 61 and the first door 71 are formed of, for example, a transparent acrylic resin. The first door 71 is of a sliding door type and includes a plurality of, for example, two doors 71a and 71b arranged on the left and right. A handle 79 is attached to each of the doors 71a and 71b on their outer surfaces. These doors 71a and 71b are slidably fitted in a groove provided on the lower surface of the upper wall 3 and a groove provided on the upper surface of the partition wall 5, respectively. The drying chamber 11 includes a first front wall 61, a first door 71, an upper wall 3 of the housing 2, a first partition wall 5, and upper portions of left and right side walls 8 and 9 of the housing 2. The first space S1 surrounded and closed by these is formed. A first display shelf (food tray) 18 is installed in the space S <b> 1 of the first storage chamber 11. Further, a second storage chamber 12 is stored below the first storage chamber 11.

  The second storage chamber 12 is stored in the first storage chamber 11 in a state of being disposed on the bottom wall (first partition wall 5) of the first storage chamber 11. Although the second storage chamber 12 is also a part of the display chamber 10, the translucent second front wall 62 provided at a position facing the first front wall 61, and the first door 71 are opposed to each other. A translucent second door 72 provided at a position to be positioned, an upper wall 15 serving also as a second display shelf (food tray) of the drying space S1, and left and right side walls 16 and 17, A space S2 closed inside the drying space S1 can be constituted by 15, 16 and 17 and the first partition wall (lower wall) 5 constituting the floor. Therefore, the second space S2 is indirectly heated from the surroundings by the warm air supplied by the warm air supply unit 20 (air that has been heated to reduce the relative humidity), and the temperature is about 65 ° C to 70 ° C. It has been adjusted. However, since the low-humidity warm air (air that has been heated and the relative humidity has decreased) does not enter the second space S2, the second space S2 has a low humidity unlike the first space S1. The humidity is not adjusted. Therefore, the second space S2 can be controlled independently of the first space S1 in terms of humidity, and the humidity of the second space S2 depends on the moisture released from the displayed product. Can be controlled. Therefore, by displaying products that have a “moist” texture, that is, products that contain a relatively high amount of moisture, the moisture released from the product will result in a relatively humid atmosphere, such as about 70% humidity. The inside of the second space S2 can be made. For this reason, the second storage room 12 is for displaying products that have a moist texture (such as products that are preferably stored at high temperature and high humidity), such as yakitori, among cooked products. Can be used.

  The 2nd front wall 62 and the 2nd door 72 of the 2nd storage chamber 12 are sliding door types, for example, are formed with transparent acrylic resin etc. The second door 72 includes two doors 72a and 72b. These doors 72a and 72b are slidably fitted in grooves provided on the lower surface of the second display shelf 15 and grooves provided on the upper surface of the first partition wall 5, respectively. The second door 72 may be a swing door that is pivoted by a hinge. The swing door may be a single-piece structure or a plurality of pieces, and is not limited to the left and right, and may be a type of door that turns up and down. A third display shelf (food tray) 19 is stored in the high humidity chamber 12.

  The display chamber 10 is in a state in which the second storage chamber 12 is stored in the lower portion of the first storage chamber 11, and the upper portion of the first storage chamber 11 is lined up with display shelves 18 and 15 so as to have a high temperature and low humidity. The product display space S1 suitable for storage in the first storage chamber 11, and the interior of the second storage chamber 12 below the first storage chamber 11 is a product display space S2 suitable for storage in high temperature and humidity. . A space S3 is provided between the first front wall 61 and the second front wall 62, and this space S3 is supplied from the hot air supply unit 20 disposed below the display chamber 10 to a high temperature and low humidity. Is part of a path for circulating the warm air to the storage space S1 in the upper part of the display chamber 10. A gap S4 is also provided between the first door 71 and the second door 72. This gap S4 also becomes a part of a path for circulating the hot air.

  The hot air supply unit 20 is disposed below the display chamber 10 with the first partition wall 5 interposed therebetween. The first partition 5 has a position corresponding to the gap S4 between the first door 71 and the second door 72, and a gap S3 between the first front wall 61 and the second front wall 62. Openings 81, 82, and 83 are provided at three locations, a position corresponding to, and a position corresponding to the second storage chamber 12. The hot air supply unit 20 includes a fan 21 for supplying hot air to the display chamber 10, and a heater 22 disposed on the outlet side of the fan 21. In this system, a certain amount of air leaks from the door 71 to the outside from the first storage chamber 11, fresh air is introduced from the direction of the storage unit 30, and the temperature of the fresh air is raised by the heater 22. It generates dry hot air with low humidity (hot air with low humidity). Dehumidification using a dehumidifying agent containing silica gel or activated carbon or a small cooling unit (for example, Peltier element) to remove moisture contained in the air collected from the first storage chamber 11 It is also possible to install a device. After dehumidifying with the cooling unit and heating with the heater, a dehumidifying device (humidity control means) is provided to control the desired humidity with the humidifier, thereby circulating in the first storage chamber 11 (in the space S1). It is also possible to actively control the humidity of the warm air that is generated. A deodorizing function may be added to such a dehumidifying device.

  In the hot air supply unit 20, the heater 22 includes a first door 71 and a second door provided on the rearmost side of the three openings 81, 82, and 83 provided in the first partition wall 5. 72 is provided in the vicinity of the first opening 81 corresponding to the gap S4 between the first opening 81 and the second opening 72. The fan 21 is provided at a substantially central portion of the hot air supply unit housing section A2, and a second opening 82 corresponding to the gap S3 between the first front wall 61 and the second front wall 62; It arrange | positions so that it may inhale from the 3rd opening 83 corresponding to the 2nd storage chamber 12, and it blows toward the heater 22 side. Accordingly, the first opening 81 is a hot air outlet, and the second opening 82 is a hot air inlet. The third opening 83 is provided with a damper 84 that opens and closes in conjunction with a humidity sensor installed in the second storage chamber 12. If the humidity in the space S2 in the second storage chamber 12 becomes too high, the damper 84 opens and sucks in air, lowers the pressure in the second storage chamber 12, and the second display shelf (food tray) in the drying space S1. The hot air that has been dried is drawn into the second space S2 through a vent hole (not shown) provided in the upper wall 15 that also serves as the second wall S2. Further, for example, the damper 84 of the third opening 83 is fully opened, and the second door 72 is opened to place the interior of the second storage chamber 12 in a dry atmosphere. The section A2 in which the hot air supply unit 20 is housed is opaque including the front and rear walls 28 and the wall 29 that is the rear wall of the section A2, so that the internal devices cannot be seen at least from the front. ing.

  In a normal operation state, first, when the heater 22 and the fan 21 of the hot air supply unit 20 are operated, the relatively low-humidity hot air that has been heated and the relative humidity has decreased is shown by a solid arrow in FIG. The air is blown out from the first opening 81 into the first storage chamber 11. In the first storage chamber 11, first, a space that passes through the gap S <b> 4 between the first door 71 and the second door 72 and in which the display shelf 15 above the second storage chamber 12 is disposed. S1 is reached. Further, the air passes through the gap S3 between the first front wall 61 and the second front wall 62, and is sucked into the hot air supply unit 20 through the second opening 82 and collected. That is, the path for circulating the hot air includes the gap S3, the space S1, and the gap S4.

  The product displayed in the drying space S1 is heated by the circulation of the low-humidity warm air, and the moisture released by itself is carried. Therefore, the atmosphere of the drying space S1 is a space suitable for displaying products that are maintained at high temperature and low humidity and that should be stored at high temperature and low humidity (space with a humidity of about 20% to 30% and a temperature of about 65 ° C to 70 ° C. )

  On the other hand, the space S2 in the second storage chamber 12 is indirectly heated by the warm air circulating in the drying space S1, and thus is maintained at the same temperature as the drying space S1. On the other hand, the warm air basically does not enter the inside of the second storage chamber 12, so moisture released from the displayed merchandise is not carried. Therefore, the humidity of the space S2 in the second storage chamber 12 is determined depending on the moisture released from the products displayed in the space. In many cases, a large amount of moisture is released from the cooked product. Therefore, the space S2 becomes a humid atmosphere due to the moisture released from the cooked product.

  When the humidity of the space S2 becomes higher than a desired value, the humidity can be lowered by controlling the opening degree of the damper 84. If the relative humidity is 90% or in the vicinity thereof, condensation tends to occur depending on conditions, which is not preferable for a showcase. Therefore, even if the atmosphere of the space S2 inside the second storage chamber 12 is preferably humid, it is preferable to control the relative humidity at an upper limit of about 70 to 80%.

  When the humidity in the space S2 becomes higher than the set value, the damper 84 is opened with a predetermined opening degree and the third opening 83 is opened as indicated by a broken line in FIG. Thereby, the low-humidity warm air in the drying space S1 flows into the space S2 from the hole of the upper wall 15, the gap of the second door, etc., as shown by the broken line arrow in FIG. . As a result, the space S2 is maintained under conditions suitable for displaying commodities that should be stored at high temperature and high humidity (a space of about 70% humidity and a temperature of 65 ° C. to 70 ° C.).

  As described above, according to the showcase device 1a, the drying space S1 can be maintained in a state suitable for displaying products that are desirably stored at high temperature and low humidity, and the high humidity space S2 It can be maintained in a state suitable for displaying products that are desired to be stored at high temperature and high humidity.

  Moreover, in the state where the hot air supply unit 20 is driven, the dried warm air is always in circulation in the drying space S1. Therefore, the products displayed in the drying space S1 can be held in a more “crisp” state. Further, in the state where the hot air supply unit 20 is driven, the inside of the high humidity chamber S2 is always heated, but air is not circulating. Accordingly, the products displayed in the high-humidity space S2 can be held in a more fresh and “moist” state.

  In addition, the display chamber 10 has a second storage chamber 12 stored in a dry space constituted by the first storage chamber 11, and the second storage chamber 12 does not directly face the outside world. The side facing the outside becomes an atmosphere of high temperature and low humidity. Therefore, even if the surface of the display room 10 is exposed to the cold air of the air conditioner of the store where the showcase device 1a is installed and the temperature is suddenly lowered, there is little possibility that condensation occurs inside the display room 10. . In particular, since the gap S3 between the first front wall 61 and the second front wall 62 is part of the path for circulating hot air, the low-humidity hot air is Force ventilation between 62. Therefore, even if S3 is narrowed between the first front wall 61 and the second front wall 62, moisture hardly accumulates and condensation is unlikely to occur. Further, even if S3 is narrowed between the first front wall 61 and the second front wall 62, the temperature drop due to the cold air of the outside environment, that is, the air conditioning in the store, may be in the second front wall 62 or inside thereof. It is difficult. Therefore, even if the second front wall 62 in which the inside is in a hot and humid atmosphere is brought close to the first front wall 61, dew condensation is unlikely to occur inside the second front wall 62. For this reason, the translucent second front wall 62 can be advanced in the direction of the translucent first front wall 61 without increasing the possibility of dew condensation, and during these steps, S3 By bringing them closer, it is possible to provide a showcase device in which products displayed in the space S <b> 2 inside the second front wall 62 can be easily seen from the outside of the first front wall 61.

  Moreover, in this showcase apparatus 1a, it is low-humidity warm air (air with low relative humidity) that may leak from the first storage chamber 11 on the outside, and condensation will occur even if it leaks. The possibility of doing is small. Even if high-humidity air leaks from the second storage chamber 12, the leaking destination is the first closed space S1 in a high-temperature atmosphere with lower humidity, and the possibility of condensation is small. .

  Furthermore, the second closed space S2 has a high-temperature and high-humidity atmosphere, and when the second door 72 is opened to display or take out products in the second closed space S2, the humid air Is leaked to the first closed space S1 in a low-humidity, high-temperature atmosphere lower than that. When the second door 72 is opened, the first door 71 is also open, but during that time, low-humidity warm air (air with low relative humidity) is forcibly circulated in S4, so that hot and humid air is Can be prevented from leaking out.

  The showcase device 1a of the present example is preferably arranged so that the front side is a store (inside the store) side that is easily noticed by the customer, and the rear side is the counter side where the store clerk is resident. Since the 1st and 2nd front walls 61 and 62 have translucency, the goods displayed in 1st and 2nd space S1 and S2 can be visually recognized from the front side favorably. Further, by opening the first door 71, the first space S1 can be opened toward the outside (rearward, clerk side). Furthermore, by opening the second door 72, the second space S2 can be opened toward the outside (rearward, clerk side). Therefore, the products displayed in the first space S1 and the second space S2 can be easily taken out from the rear side.

  Even with a highly sealed door, there is always the possibility of air leaking in the display room. In particular, when putting in and out goods, it is not possible to stop the air in the display room from leaking out. In this showcase apparatus 1a, the air that leaks to the outside when a product is taken in and out of the first storage chamber 11 is a low-humidity hot air, and there is little possibility of dew condensation even if leaked. On the contrary, a certain amount of air is always released from the first storage chamber 11 to the outside, and the fresh storage air that has been heated to lower the relative humidity is supplied to the first storage chamber 11. It is possible to keep the atmosphere of the internal space S1 at high temperature and low humidity.

  When a product is taken in and out of the second storage chamber 12, high-humidity air leaks from the second storage chamber 12, but the destination of the leakage is the dry space S1 in a low-humidity and high-temperature atmosphere. For this reason, also in this case, there is little possibility that condensation will occur. Further, between the first door 71 and the second door 72, low-humidity warm air blows upward from the first opening 81. Therefore, in a state where the second door 72 is opened, the pressure on the outside of the second door 72 is higher than that on the inside of the second door 72 where the humidity is high, and the humid air leaks out. The amount is small. Furthermore, the leaked high-humidity air is mixed by the low-humidity hot air and carried upward, so that there is little possibility of causing condensation.

  Therefore, like the showcase device 1a of the present example, a circulation path in which warm air is blown up to S4 between the rear door 71 and the door 72 and sucked from S3 between the front walls 61 and 62 is a suitable one. It is an example. In particular, it is easy to prevent the occurrence of dew condensation by blowing a large amount of hot air at a high speed to the door portion where the amount of leakage of high humidity air may be large. Further, since the gap S3 between the front walls 61 and 62 becomes small and becomes a part where pressure loss occurs, by making this part the suction side, it is possible to prevent a decrease in fan efficiency and to generate noise, vibration, and the like. It is easy to deter.

  Thus, according to this showcase device 1a, a door such as a sliding door with low airtightness can be adopted as a door for opening and closing the first storage chamber 11, and there is little possibility of condensation. For this reason, a door with a simple structure can be applied. The door for opening and closing the storage chamber may be a swing type door, but a space for the door to swing behind the storage chambers 11 and 12 is required. According to the showcase device 1a of this example configured to open and close the first storage chamber 11 by the sliding door type first door 71, when the goods displayed in the storage chamber 11 are taken in and out from the rear side. Little space is needed to open and close the door. Furthermore, since the sliding doors 71a and 71b are used, it is possible to put products in and out of the storage rooms 11 and 12 while cooking using the cooking space 50.

  The lower side of the second partition wall 6 of the showcase device 1a, that is, the lower side of the housing 2 is a storage unit 30 that can be accessed from the store clerk side in the rear counter. Therefore, the front lower side of the housing 2 is an opaque wall 37. The storage unit 30 stores a refrigerator 31 having a lid 32 that can be accessed from the rear, and a cooling unit 35 for cooling the inside of the refrigerator 31 is stored in the back thereof. Spaces for exhaust paths 38 and 39 for radiating heat from the cooling unit 35 are secured above and below the refrigerator 31. The cooling unit 35 includes a Peltier element 34, absorbs heat from the inside of the refrigerator 31, and exhausts heat to the exhaust path 39.

  The second partition 6 has an opening (communication hole) 40 that connects an upper exhaust path 39 through which high-temperature exhaust is discharged and the intake side of the fan of the hot air supply unit 20. Therefore, the exhaust gas heated to exhaust heat by the cooling unit 35 and having a high temperature is supplied to the hot air supply unit 20 as fresh air, pressurized by the fan 21, and further heated to a desired temperature by the heater 22. It is heated and blown out into the first storage chamber 11.

  In the first storage chamber 11, air (hot air) whose relative humidity is reduced by heating the circulating air can be supplied to the first storage chamber 11. When moisture is released from the cooked product stored in the first storage chamber 11, it may be difficult to maintain a dry state simply by circulating hot air. In such a case, one way to generate hot air of high temperature and low humidity is to dehumidify the circulating air by a suitable method. It is possible to employ a hygroscopic agent, but in this case, it is necessary to refresh periodically. It is also possible to provide a cooling unit and discharge moisture as drain. In this case, it is possible to save heat energy by providing a heat exchanger or the like for heating the cooled air. Further, in order to prevent the inside of the first storage chamber 11 from being extremely dried, it is possible to provide a humidifier and control the humidity of the hot air supplied to the first storage chamber 11.

  One of the other methods for generating hot air with high temperature and low humidity is to heat the outside air to generate hot air with low relative humidity.

  In order to put in the outside air (fresh air), it is necessary to release the air that has become high temperature, and energy is consumed to heat the low temperature outside air. In the showcase device 1a, energy consumption can be reduced by using the exhaust heat of the cooling unit 35 of the refrigerator 31 in order to heat fresh air.

  Moreover, in this showcase apparatus 1a, a working table 51 that functions as a cooking table is provided behind the display chamber 10 and behind the hot air supply unit 20, and the cooked product is displayed while cooking. It can be sold side by side. The front wall and the rear doors 71 and 72 are transparent, and behind the display room 10, the store clerk can look forward and cook while looking over the store from the inside of the counter. Can be observed. Moreover, it is possible to store the material required for cooking in the refrigerator 31, and the clerk can also access the refrigerator 31 from the inside of the counter with the front facing. Therefore, a series of operations for taking out frozen food, cooking it, and displaying it can be basically performed while looking at the direction in the store, and the opportunity for the store clerk to turn away from the customer can be reduced. Can improve the service. In addition, since the inside of the store can always be observed, it is also effective in preventing theft. Furthermore, it is possible to immediately cope with a situation where there is a possibility of danger to the store clerk such as a thief.

  In the showcase device of the present invention, the working table 51 for cooking is not essential, and may be a showcase device that does not include a table.

  FIG. 4 is a perspective view of a showcase device according to the second embodiment of the present invention as viewed from the front side. FIG. 5 is a perspective view of the showcase device of FIG. 4 viewed from the rear side with the rear door (first door) closed. FIG. 6 is a perspective view of the showcase device of FIG. 4 viewed from the rear side with the first door opened. FIG. 7 shows a schematic configuration of the showcase of FIG. 4 in a longitudinal sectional view. The showcase apparatus shown using FIGS. 4 to 7 is to provide a showcase apparatus that is unlikely to cause condensation on the front surface and that can easily open the first storage chamber and the second storage chamber. It is an example of the embodiment which aimed at one.

  The showcase device 1b of this example is also a device or unit suitable for displaying and selling cooked food as products in a store such as a convenience store, and functions as a showcase for displaying products, It also has a function as a device for keeping the product warm (stored).

  The showcase device 1 b includes a display room (showcase) 10, and a hot air supply unit 20 and a storage unit 30 arranged below the display room 10. The display chamber 10 includes a first storage chamber 11 and a second storage chamber 12 disposed therein. The storage unit 30 is provided with a cool box 31 including a refrigerator 31 a and a freezer 31 b and a cooling unit 35 for cooling the inside of the cool box 31.

  The housing 2 of the showcase device 1b has a box shape that is long in the vertical direction as a whole, and is placed between the upper wall 3 facing the ceiling of the store and the lower wall 4 facing the floor when installed in the store. Partition wall 5. The showcase device 1b is roughly provided with three functional sections A1, A2 and A3. A space between the upper wall 3 and the partition wall 5 is a section A1 of the display chamber 10, and the cooked food can be displayed while being kept warm. The lower front side of the display chamber 10 is a section A2 of the hot air supply unit 20 for supplying hot air to the display chamber 10. The rear side of the section A2, that is, the lower rear side of the display chamber 10, is the section A3 of the storage unit 30, in which the refrigerator 31a, the freezer 31b, and the cooling unit 35 are stored. The front lower side of the housing 2 is an opaque wall 37, and the hot air supply unit 20 and the storage unit 30 are hidden from the front side.

  The first storage room 11 is a first display for displaying products that have a “crisp” texture such as American dogs (products that are preferably stored at high temperature and low humidity) among the cooked products. This is for forming a closed space S1. The first space S1 has a humidity of about 20% to 30%, as in the first embodiment, by hot air of low humidity (heated air having a low relative humidity) supplied from the hot air supply unit 20. The temperature is adjusted to about 65 ° C to 70 ° C.

  The first storage chamber 11 includes a translucent canopy 3a, a translucent first front wall 61, a translucent first door 71 for opening and closing the first storage chamber 11, Translucent first side walls 101a and 101b are provided. The canopy 3 a constitutes the upper wall 3 of the housing 2, the first front wall 61 constitutes the upper front wall of the housing 2, and the first side walls 101 a and 101 b are the upper parts of the side walls 8 and 9 of the housing 2. Is configured. The first door 71 is, for example, a swing type (folding door, double door type) and includes two doors 73a and 73b arranged on the left and right. These doors 73a and 73b have handles 79 attached to their outer surfaces. The first storage chamber 11 is surrounded and closed by a first front wall 61, a first door 71, first side walls 101a and 101b, a canopy 3a, and a first partition wall 5. 1 space S1 is formed. A first display shelf (food tray) 18 is installed in the space S <b> 1 of the first storage chamber 11. A second storage chamber 12 is stored below the first storage chamber 11, and the first display shelf 18 also serves as the upper wall of the second storage chamber 12. A built-in type illumination L is disposed above the housing 2.

  The second storage chamber 12 is stored in the first storage chamber 11 with the bottom wall (partition wall) 5 of the first storage chamber 11 as a common bottom wall. The second storage chamber 12 is also a part of the display chamber 10, but the translucent second front wall 62 provided at a position facing the first front wall 61, and the first side walls 101a and 101b. Light-transmitting second side walls 102a and 102b provided at positions facing each other. The second storage chamber 12 is surrounded by the second front wall 62, the second side walls 102a and 102b, the first display shelf 18, and the partition wall 5, and is opened in the direction of the first door 71. It is opened and closed by the first door 71. When the first door 71 closes the first storage chamber 11 at the open end of the second storage chamber 12, a sealing member (in contact with the first door 71 (doors 73 a and 73 b)) 110) is provided.

  Therefore, in the showcase device 1b, the first storage chamber 11 and the second storage chamber 12 can be opened by opening the first door 71. Therefore, the second storage room 12 can be accessed with a single action, and the product in the display room 10 can be easily taken out. On the other hand, when the first door 71 is closed, the seal member 110 at the end of the second storage chamber 12 and the first door 71 come into contact with each other, and the second storage chamber 12 enters the outside (outside the display chamber 10). In addition to being isolated (sealed), the first storage chamber 11 is also isolated (sealed). Therefore, it is difficult for air to leak from the second storage chamber 12 by closing the first door 71.

  In the showcase device 1b of this example, the space S2 closed inside the drying space S1 can be configured by these. Similar to the first embodiment, the second space S2 can be controlled depending on the moisture released from the displayed product, and has a relatively humid atmosphere. A second display shelf 15 and a third display shelf 19 are stored inside the second storage chamber 12, and the second storage chamber 12 is, for example, a yakitori among cooked items. It can be used to display products that have a moist texture (products that should be stored at high temperature and high humidity). Further, similarly to the first embodiment, the second storage chamber 12 may be provided with a damper that opens and closes in conjunction with the humidity sensor, and further the humidity of the second space S2 is changed to the first space. It can be controlled independently of S1.

  Also in the showcase device 1b of this example, a gap S3 is provided between the first front wall 61 and the second front wall 62. In the showcase device 1b of this example, the gap S3 is a part of a path for supplying hot air. Further, the first side wall 101b that constitutes one side portion that is different in direction with respect to the front walls 61 and 62, and the second side wall 102a, and the opposite side portion. And the second side wall 102b are provided with gaps S5 and S6, respectively. These voids S5 and S6 are part of a path for sucking warm air. Accordingly, the warm air circulates through the gaps S3, S5 and S6.

  The first storage chamber 11 and the second storage are provided by a first door 71 having swing type doors (spreading doors) 73a and 73b and common to the first storage chamber 11 and the second storage chamber 12. In the showcase device 1b of the type that opens the chamber 12 at once (with one action), it is difficult to configure a path for circulating hot air to the first door 71 side. Therefore, as in this example, S3 between the first front wall 61 and the second front wall 62, S5 between the first side wall 101a and the second side wall 102a, the first side wall 101b and the second side wall. A showcase device 1b including a warm air circulation path including S6 between the side wall 102b of the first case is a preferred example of a showcase device having a common door 71. Further, the front of the display chamber 10 is configured by circulating hot air between S5 between the first side wall 101a and the second side wall 102a and between S1 between the first side wall 101b and the second side wall 102b. The same effect as circulating hot air between S1 between the first front wall 61 and the second front wall 62 can also be obtained at the side of the showcase 10.

  That is, even if S5 between the side walls 101a and 102a and S6 between the side walls 101b and 102b are narrowed, moisture hardly accumulates and condensation is unlikely to occur. Furthermore, even if the space (gap) S5 and S6 between these is narrowed, the temperature drop due to the cold air of the outside, that is, the air conditioning in the store, does not easily reach the second storage room 12. Therefore, even if the wall of the second storage chamber 12 in which the inside is in a hot and humid atmosphere is brought close to the wall of the first storage chamber 11, condensation is unlikely to occur inside the second storage chamber. For this reason, it is easy to see the products displayed in the space S2 inside the second storage chamber 12 from the outside of the first storage chamber 11, and it is possible to provide a showcase device that is compact and has a large storage capacity.

  The hot air supply unit 20 is disposed below the front side of the display chamber 10 with the partition wall 5 interposed therebetween. The partition 5 has a position corresponding to the gap S5 between the first side wall 101a and the second side wall 102a, and a position corresponding to the gap S6 between the first side wall 101b and the second side wall 102b. Openings 111a, 111b, and 112 are provided at three locations, corresponding to the space S3 between the first front wall 61 and the second front wall 62. Further, the hot air supply unit 20 includes a path 120 (see FIG. 7) in which the hot air is supplied to the first storage chamber 11 after contacting the bottom wall 5 of the second storage chamber 12. Yes. Note that, similarly to the first embodiment, the exhaust heat from the cooling unit 35 may be configured to be drawn by the warm air supply unit 20 (exhaust heat is drawn from the region A3 to the region A2).

  The hot air supply unit 20 includes a fan 21 for supplying hot air to the display chamber 10, and a heater 22 disposed on the outlet side of the fan 21. The fan 21 has an opening 111a corresponding to the gap S5 between the first side wall 101a and the second side wall 102a, and an opening corresponding to the gap S6 between the first side wall 101b and the second side wall 102b. It arrange | positions so that it may inhale from 111b and it may blow toward the heater side. The heater 22 is disposed on the rear side of the housing 2 with respect to the fan 21. For this reason, as shown in FIG. 7, the warm air heated to a desired temperature by the fan 21 and the heater 22 is applied to the lower side of the bottom wall 5 of the second storage chamber 12 as shown as the path 120. It flows forward along the bottom wall 5 so as to come into contact, and is blown into the display chamber 10 from the opening 112 corresponding to the gap S3 between the first front wall 61 and the second front wall 62. Therefore, the air inside the first space 11 circulates using the openings 111a and 111b as the suction inlet and the opening 112 as the outlet, respectively, and the reheated warm air passes through the second space 12 via the bottom wall 5. After being indirectly heated, it is blown out into the first space 11.

  That is, in a normal operation state, first, when the heater 22 and the fan 21 of the hot air supply unit 20 are operated, the hot air having a relatively low humidity, which is heated and the relative humidity is reduced, is indicated by a solid arrow in FIG. As described above, the air is blown out from the opening 112 into the first storage chamber 11. In the first storage chamber 11, first, it passes through the space S <b> 3 between the first front wall 61 and the second front wall 62 and reaches the space S <b> 1. Thereafter, the warm air is divided into left and right, passes through the gap S5 between the first side wall 101a and the second side wall 102a, and S6 between the first side wall 101b and the second side wall 102b, and opens 111a and 111b. The air is sucked into the hot air supply unit 20 and collected.

  The product displayed in the drying space S1 is heated by the circulation of the low-humidity warm air, and the moisture released by itself is carried. Therefore, similarly to the showcase device 1a of the first embodiment, also in this example, the atmosphere of the drying space S1 is maintained at high temperature and low humidity. Since the space S2 inside the second storage chamber 12 is indirectly heated by the warm air circulating in the drying space S1 and the warm air passing through the path 120, the temperature S2 is maintained at the same level as the drying space S1. The On the other hand, the warm air basically does not enter the inside of the second storage chamber 12, so moisture released from the displayed merchandise is not carried. Therefore, the humidity of the space S2 in the second storage chamber 12 is determined depending on the moisture released from the products displayed in the space S2, and becomes a high temperature and humidity atmosphere.

  FIG. 8 is a cross-sectional view in which the vicinity of the cooling unit provided in the showcase device of FIG. 4 is cut in the horizontal direction.

  The lower side of the partition wall 5 of the showcase device 1b, that is, the lower side of the housing 2 is a storage unit 30 that can be accessed from the store clerk in the rear counter. The storage unit 30 stores a cool box 31 having lids 32a and 32b that can be accessed from the rear. A cooling unit 35 for cooling the inside of the cool box 31 is stored in the back, that is, the front side. Yes. Further, in the cooling unit 35, a space for an exhaust path 36 for radiating the exhaust heat from the cooling unit 35 to the outside is secured, and the exhaust heat is opened to the rear side of the showcase device 1b. Is sucked in and discharged from the lower part of the showcase device 1b to the outside.

  The storage unit 30 includes a refrigerator 31a and a freezer 31b. For this reason, in this example, instead of the Peltier element unit, a cooling unit 35 having a high cooling capacity for cooling the refrigerant by circulating it with a compressor is employed. The cooling unit 35 includes a compressor 35a, a condenser 35b, an evaporator 35c, a circulation fan 35d, and a heat radiating fan 35e. Further, in the storage unit 30, the inside of the freezer 31b is cooled by the cooling unit 35, the air inside the freezer 31b is circulated by the circulation fan 35d, and the cold air in the freezer 31b is led to the refrigerator 31a to cool the refrigerator 31a. I have to. For this reason, although not shown in figure, the damper unit is provided between the freezer 31b and the refrigerator 31a, and it is comprised so that cold air may be drawn into a refrigerator from a freezer.

  Further, an exhaust path 36 for exhausting heat from the condenser 35b is formed in the section A3. When the heat radiating fan 35e is operated, the air taken in from the opening 36a that opens to the rear side of the showcase device 1b passes through the condenser 35b and passes by the side of the freezer 31b as shown by the solid line arrow in FIG. Then, it is discharged to the outside from the lower part of the showcase device 1b.
