Description

[Technical field]

[0001] The present invention relates to a sterilization storage cabinet in which items such as tableware stored in a storage chamber inside the cabinet are heated by a heating device to sterilize and dry the items, and then the storage chamber is cooled by a cooling device to lower the temperature of the items. [Background technology]

[0002] In kitchen facilities such as hospitals, schools, and restaurants, disinfection cabinets are preferably used to store dishes, chopsticks, knives, forks, etc. (hereinafter referred to as "stored items") that have been washed and have water droplets on them, and then dry them in a disinfected state. That is, disinfection cabinets are equipped with a heating device such as an electric heater and a blower fan that forcibly circulates the air heated by the heating device inside the cabinet, and heat the stored items with water droplets to a high temperature with hot air to sterilize and dry them.

[0003] As shown in FIG. 11, in a typical disinfection storage cabinet 10, a circulation path 14 provided with a blower fan 28 and a storage room 16 for storing stored items are defined inside (inside) a housing (insulated box) 12 with a thermal insulation structure. The circulation path 14 is composed of an upper space 14a and side spaces 14b, 14b communicating therewith, and the upper space 14a is defined on the upper surface side of the top plate 22 of the storage room 16, and the side spaces 14b, 14b are defined on the outer surface sides of both side plates 24, 24 facing each other in the width direction of the storage room 16. The storage room 16 communicates with the upper space 14a through an intake port 22a formed in the top plate 22, and communicates with the side spaces 14b, 14b through a plurality of outlets 24a formed in the side plates 24, 24. The fan motor 29 for driving the blower fan 28 is disposed in a machine room 18 defined in the upper part of the housing 12.

[0004] In the upper space 14a of the circulation path 14, an electric heater 30, which is a heating device, is disposed so as to revolve around a blower fan 28. The blower fan 28 draws air from the storage room 16 into the upper space 14a through the suction port 22a, and brings the drawn-in air into contact with the electric heater 30. Therefore, the air drawn into the upper space 14a from the storage room 16 side by the operation of the blower fan 28 becomes hot air, flows into the side spaces 14b, 14b, and is blown out from the air outlet 24a of the side panel 24 into the storage room 16, heating the stored items in the storage room 16.

[0005] The sterilization storage cabinet 10 is also provided with an exhaust duct 32 that connects the circulation path 14 to the outside of the cabinet, and this exhaust duct 32 is structured to be closed or opened by a damper 34. That is, the stored object is sterilized by closing the exhaust duct 32 and heating the stored object in a state where the moisture in the storage chamber 16 is not discharged to the outside. Also, the damper 34 of the exhaust duct 32 is opened and the stored object is heated in a state where the moisture in the storage chamber 16 is discharged to the outside, so that the stored object is dried.

[0006] In kitchen facilities, a method of preserving and serving food is sometimes used in which cooked food (food) is once cooled to a chilled state, served on tableware, and then reheated at the timing of serving the food. In this case, it is desirable that the tableware is sufficiently cooled when the food is served. In contrast, in the above-mentioned sterilization storage cabinet 10, it takes time for the stored items to cool sufficiently after sterilization and drying, and there is a problem in that cold tableware, etc. cannot be prepared quickly. For example, if the door is fully opened to take in outside air into the storage room 16, the time it takes for the stored items to cool can be shortened, but in this case, the air from outside the storage room will come into contact with the stored items in the storage room 16 that have been sterilized with great care, causing hygiene problems. Considering these circumstances, it is preferable to provide a cooling device for cooling the inside of the storage cabinet 10. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2003-310527 A Summary of the Invention [Problem to be solved by the invention]

[0008] By mounting a cooling device on the disinfection storage cabinet 10, the stored items in a high temperature state after disinfection and drying can be quickly cooled to the required temperature by the operation of the cooling device. However, as the temperature inside the cabinet drops, the outer surface of the disinfection storage cabinet 10 gradually cools, and condensation occurs around the opening (the opening for storing or taking out the stored items) of the housing 12 that is opened and closed by the door. In this case, as a countermeasure against condensation, it is possible to install an electric heater (hereinafter referred to as a "condensation prevention heater") on the periphery of the opening in the housing 12. Note that the condensation prevention heater can be, for example, a linear or band-shaped heater that can be bent and deformed, and can be arranged in a serpentine manner so as to go back and forth multiple times around the installation target on the periphery of the opening.

[0009] When installing multiple dew condensation prevention heaters, the cost per part can be reduced by using heaters with the same specifications (same shape and performance). However, even on the periphery of the air opening, the ease of cooling (tendency of temperature change (temperature drop)) during cooling operation differs depending on the position, and if dew condensation prevention heaters with the same specifications are installed on multiple installation targets around the periphery of the air opening, the specifications of the dew condensation prevention heater must be determined according to the temperature change tendency of one of the installation targets, and the other installation targets will be heated by the dew condensation prevention heater more than necessary during cooling operation. In other words, dew condensation prevention heaters with excessive performance and excessive quality will be used, which will ultimately result in waste in power consumption and parts costs.

[0010] Therefore, in consideration of the above-mentioned problems inherent in conventional disinfection storage cabinets, the present invention has been proposed to optimally solve these problems, and aims to provide a disinfection storage cabinet that can prevent the occurrence of condensation associated with cooling operation at low cost. [Means for solving the problem]

[0011] In order to overcome the above problems and achieve the intended purpose, First Measure teeth, A disinfection storage cabinet in which a housing has a storage chamber for storing items and an air circulation path defined therein, a vent is formed to connect the storage chamber to the outside, the vent can be opened and closed with a door, and air heated by a heating device can be introduced from the circulation path into the storage chamber, The storage compartment is provided with a cooling device capable of cooling the interior of the storage compartment, and the air cooled by the cooling device is configured to be introduced into the storage compartment through the circulation path. The gist of the invention is that the housing is provided with anti-condensation heaters for multiple installation objects located around the door, the heaters having different heat generation amounts depending on the difference in the temperature change tendency of the installation objects during cooling operation. This configuration According to the method, by providing anti-condensation heaters to a plurality of installation objects located around the door of the housing, it is possible to prevent condensation from occurring near the boundary between the housing and the door. In this case, by providing anti-condensation heaters with different heat values ​​to each installation object according to the temperature change tendency of the installation object during cooling operation, it is possible to reduce component costs and wasteful power consumption.

[0012] Second Measure teeth, The door includes a left door that rotates about an axis along the left side of the passage opening, and a right door that rotates about an axis along the right side of the passage opening, The housing is provided with an upper partition facing the upper edge of the back surface of both doors, The gist of the invention is that the anti-condensation heater, which is to be installed on the upper partition, has a horizontal portion extending in the left-right direction along the upper end surfaces of both doors, and a vertical portion extending in the up-down direction along the joint between the two doors. This configurationAccording to the above, during cooling operation, the occurrence of condensation on the surface of the upper partition and the upper end face of the door can be suppressed by heating the horizontal part of the condensation prevention heater, and the occurrence of condensation on the surface of the upper partition and the open end face of the door can be suppressed by heating the vertical part of the condensation prevention heater. In other words, since the condensation prevention heater that is installed on the upper partition can prevent condensation around the door joint, it is possible to omit the installation of the condensation prevention heater on the door, which can reduce costs and prevent the manufacturing process from becoming complicated.

[0013] The third method is The housing includes a horizontal partition facing a side edge portion of a rear surface of the door and a side frame plate facing a side end surface of the door, The door is provided on the rear surface thereof. Tapa a lock configured to contact the horizontal partition when the door is closed; The anti-condensation heater, which is intended to be installed on the horizontal partition, has a first vertical portion extending in the vertical direction in a position aligned with the back side of the gasket, and a second vertical portion extending in the vertical direction in a position aligned with the back side of the side frame plate, and the first and second vertical portions are arranged along the same plane of the horizontal partition. With this configuration, during cooling operation, the heating of the first vertical portion of the condensation prevention heater can effectively prevent condensation from occurring on the horizontal partitions, etc., and the second vertical portion of the condensation prevention heater can effectively prevent condensation from occurring on the side frame panels and the side end faces of the doors. Since the condensation prevention heater is disposed so that the first and second vertical portions are along the same plane of the horizontal partition, the installation work of the condensation prevention heater is not complicated, and the installation state can be prevented from becoming unstable.

[0014] 4th Measure teeth, Equipped with an internal temperature sensor that detects the internal temperature, The gist of the present invention is that the anti-condensation heater installed on a specified installation object is activated in response to the internal temperature detected by the internal temperature sensor during cooling operation dropping to a specific temperature that is higher than the temperature that drops the surface temperature of the specified installation object to the dew point temperature. This configurationAccording to the method, the condensation prevention heater installed in the specified installation target is activated when the temperature inside the cabinet during cooling operation drops to a specific temperature, so the operation time of the condensation prevention heater can be shortened to reduce power consumption during operation and the efficiency of cooling inside the cabinet is not excessively reduced. The specific temperature inside the cabinet is higher than the temperature at which the specified installation target reaches the dew point temperature, so the occurrence of condensation on the specified installation target can be sufficiently suppressed.

[0015] 5th Measure teeth, The doors include a left door that rotates around an axis along the left side of the passage and a right door that rotates around an axis along the right side of the passage, and a partition piece is provided at the open end of one of the doors to close the joint between the two doors extending in the vertical direction from the inside of the storage room, The gist of the invention is that a heat insulator is provided between the joints of the two doors and the surface of the partition piece. This configuration According to the above, condensation can occur on the partition piece due to contact with warm air from outside the cabinet that flows into the joint between the two doors. However, by positioning a heat insulator between the joint between the two doors and the partition piece, it is possible to prevent the occurrence of such condensation with an inexpensive structure.

[0016] 6th Measure teeth, The gist of the invention is that a plate- or sheet-shaped insulator is interposed between the metal plate forming the back surface of the door and other components of the door, and is arranged along the outer peripheral edge of the door. This configuration According to the document, the temperature of the back surface of the door facing the storage room drops during cooling operation. In response to this, by disposing a plate-like or sheet-like insulator along the outer periphery of the door and interposing the insulator between the metal plate that forms the back surface of the door and other components of the door, it is possible to prevent the temperature of the components from dropping due to contact with the metal plate, and to suppress condensation on the door.

[0017] 7th Measure teeth, The door includes an inner plate disposed inside the door, a plate-shaped or sheet-shaped heat insulator, and a fixing member for fixing the heat insulator to the inner plate, the fixing member has a fitting portion between a head on one end side and a threaded portion on the other end side, the fitting portion having a diameter larger than the threaded portion and smaller than the head; The gist of the invention is that the insulation is positioned between the inner plate and the head with the threaded portion of the fixing member screwed into the inner plate, and is held in a state where the fitting portion is fitted into the inside of a fitting hole formed in the insulation. This configuration According to the method, the fitting portion provided between the screw portion and the head of the fixing member is fitted into the fitting hole of the insulation for preventing condensation. That is, the fixing member holds the insulation in a space equivalent to the dimension of the fitting portion provided between the screw portion and the head, so the head of the fixing member does not press the insulation strongly and deform it. Therefore, it is possible to prevent the screw portion from becoming loose due to the restoring force of the insulation that is deformed by being pressed by the head of the fixing member, and the rigidity of the door can be maintained.

[0018] 8th Measure teeth, The fitting hole is formed in a long hole shape along the longitudinal direction of the thermal insulator. This configuration According to the present invention, by making the fitting hole of the insulation body a long hole extending in the longitudinal direction of the insulation body, the fixed state by the fixing member can be maintained favorably even if the insulation body shrinks or warps due to temperature changes, etc. 9th Measure teeth, The door includes a left door that rotates about an axis along the left side of the passage opening, and a right door that rotates about an axis along the right side of the passage opening, A partition piece is provided at the open end of one of the doors to close the joint between the two doors extending in the vertical direction from the inside of the cabinet, and when the one door is closed and the other door is closed, a packing arranged on the back surface of the other door comes into contact with the partition piece. The gist of the present invention is that a sealing member is provided on the extended end side of the partition piece, which elastically contacts a portion of the back surface of the other door that is closer to the axis than the gasket. This configurationAccording to the present invention, the seal member, in addition to the packing, closes the gap between the partition piece and the other door, thereby improving the airtightness between the open ends of both doors. Measure 10 teeth, the partition piece includes an extending base portion and an inclined portion extending obliquely from the extending base portion to the front side, and is bent so that the surfaces of the extending base portion and the inclined portion form an obtuse angle with each other; The sealing member is arranged along the inclined portion of the partition piece, and one end side of the sealing member in the width direction elastically contacts a portion of the back surface of the other door that is closer to the axis than the gasket, while the other end side in the width direction is located closer to the interior side of the storage compartment than the extended base portion of the partition piece, so as to be able to change the air flow along the back surface of the door. This configuration According to the document, by providing the partition piece with an inclined portion that is bent at an obtuse angle to the extended base portion, the range in which the packing can deform can be narrowed and the contact area between the packing and the partition piece can be increased, thereby improving the sealing performance between the open ends of both doors. In addition, by changing the air flow along the back surface of the door with the sealing member, it is possible to suppress the occurrence of condensation due to a drop in the temperature of the partition piece when cooling operation is performed. In addition, it is possible to improve the cooling capacity during cooling operation and the heating capacity during disinfection and drying operation. 11th Measure teeth, the partition piece includes an extending base portion and an inclined portion extending obliquely from the extending base portion to the front side, and is bent so that the surfaces of the extending base portion and the inclined portion form an obtuse angle with each other; The sealing member has a plurality of parallel flexible plates spaced apart in the thickness direction, and one end side of each flexible plate in the width direction is configured to elastically contact a portion of the back surface of the other door that is closer to the axis than the gasket. This configurationAccording to the present invention, by providing the partition piece with an inclined portion that is bent at an obtuse angle to the extended base portion, the range in which the packing can deform can be narrowed and the contact area between the packing and the partition piece can be increased, thereby improving the airtightness between the open ends of both doors. Also, by providing a plurality of flexible plates on the seal member to close the gap between the partition piece and the other door, the airtightness between the open ends of both doors can be improved. 12th Measure teeth, a shielding plate disposed at a lower end of the rear surface of the door to close a gap between the door and a bottom plate of the housing; The gist of the invention is that it is provided with an auxiliary shielding plate which covers the gap between the outer edge of the shielding plate and the back surface of the door. This configuration According to the method, the occurrence of condensation due to a drop in temperature on the bottom end surface of the door and the bottom plate can be suppressed when the cooling operation is performed by using a shielding plate to prevent the air inside the cabinet from leaking out through the gap between the bottom end of the door and the bottom plate and using an auxiliary shielding plate to prevent the air inside the cabinet from leaking out through the gap between the upper edge of the shielding plate and the back surface of the door. Also, the cooling capacity during the cooling operation and the heating capacity during the disinfection and drying operation can be improved. Effect of the Invention

[0019] According to the disinfection storage cabinet of the present invention, the occurrence of condensation caused by cooling operation can be suppressed at low cost. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Next, the disinfection storage cabinet according to the present invention will be described in detail with reference to the attached drawings, taking preferred embodiments as examples. The same names and reference symbols are used for structures common to the disinfection storage cabinet 10 described with reference to FIG. 11, and detailed descriptions will be omitted. In the following description, the disinfection storage cabinet 10 will be referred to as "left" and "right" in accordance with the state of the disinfection storage cabinet 10 as seen from the front (front side) as shown in FIG. 1. In addition, when describing the front and back of a member in the following description, the outside of the cabinet will be referred to as the "front side" and the inside of the cabinet (the storage chamber 16 side) will be referred to as the "back side". For example, the front side (outside of the cabinet) of the doors 20A, 20B (described later) provided on the front side of the storage chamber 16 will be referred to as the "front side" and the rear side (inside of the cabinet) will be referred to as the "back side". In addition, the doors 20A, 20B may be provided on the rear side of the storage chamber 16 (the rear end of the housing 12), in which case the rear side (outside of the cabinet) will be referred to as the "front side" and the front side (inside of the cabinet) will be referred to as the "back side". EXAMPLES

[0022] (Overall configuration of disinfection storage cabinet 10) As described above, the disinfection storage cabinet 10 has a storage chamber 16 for storing items (items) such as tableware to be disinfected and dried, which is defined inside (inside) the rectangular box-shaped housing 12. This storage chamber 16 is connected to the outside (outside) through a passage 50a formed at the front end of the housing 12. As shown in FIG. 1, the front end of the housing 12 is provided with doors (left door 20A and right door 20B) for opening and closing the passage 50a (see FIG. 3) (hereinafter, the part of the front end of the housing 12 that forms the passage 50a may be referred to as the "passage forming part 50"). The disinfection storage cabinet 10 of the first embodiment is a so-called cart-in type disinfection storage cabinet in which a tableware cart (cart) carrying stored items is carried into the storage chamber 16 and the stored items on the tableware cart are disinfected and dried by the operation of the electric heater (heating device) 30. That is, the passage 50a is used as an entrance and exit when carrying the tableware cart into and out of the storage chamber 16.

[0023] As shown in FIG. 2, the sterilization storage cabinet 10 of the first embodiment is equipped with a refrigeration mechanism R. The refrigeration mechanism R is a mechanism in which a compressor, a condenser, an expansion valve, etc., and an evaporator 36 as a cooling device for cooling the interior of the cabinet are connected in a ring shape by refrigerant piping, and most of the evaporator 36 is disposed in the machine room 18. This refrigeration mechanism R has a plurality of evaporators 36 (specifically, two evaporators 36), and each evaporator 36 is disposed in the upper space 14a of the circulation path 14 (more specifically, on both the left and right sides of the blower fan 28). An electric heater 30 is provided on the outer periphery of the upper space 14a, and each evaporator 36 is located on the inner periphery of the electric heater 30.

[0024] (Port forming part 50) As shown in FIG. 3, the through-hole forming portion 50 of the housing 12 is provided with a columnar upper partition 52 extending left and right to form the upper edge of the opening of the through-hole 50a, and a columnar horizontal partition 53 extending up and down to form the side edge of the opening of the through-hole 50a. The bottom plate 26 forming the bottom surface of the storage chamber 16 does not have any partitions such as the upper partition 52 or the horizontal partition 53 protruding therefrom. Therefore, the lower edge of the through-hole 50a is formed on the same plane as the bottom surface of the storage chamber 16 by the flat bottom plate 26. A left door 20A that rotates around an axis along the left side (side edge) of the through-hole 50a and a right door 20B that rotates around an axis along the right side (side edge) of the through-hole 50a are provided inside the frame-shaped portion (peripheral frame 51) in front of the upper partition 52 and the horizontal partition 53 of the through-hole forming portion 50.

[0025] 3, the outer peripheral frame 51 includes an upper frame plate 51T facing the upper end surface 61 of the doors 20A, 20B, and a side frame plate 51S facing the side end surface 62 on the shaft side of the doors 20A, 20B. In addition, the front end portion of the bottom plate 26 (specifically, the range in front of the horizontal partition 53) functions as a portion of the outer peripheral frame 51 facing the lower end surface 64 of the doors 20A, 20B.

[0026] The upper partition 52 and the horizontal partition 53 are adjacent to the outer edge of the doors 20A, 20B when the passage opening 50a is closed from the back side. Specifically, the surface of the front plate 52a of the upper partition 52 faces the upper edge of the back side of the doors 20A, 20B, and the surface of the front plate 53a of the horizontal partition 53 faces the side edge (on the axis side) of the back side of the doors 20A, 20B. The upper partition 52 (the surface of the front plate 52a) faces the gap between the upper end surface 61 of the doors 20A, 20B and the upper frame plate 51T from the back side. The horizontal partition 53 (the surface of the front plate 53a) faces the side end surface 62 of the doors 20A, 20B on the axis side and the gap between the side frame plate 51S from the back side. The upper partition 52 forms the front wall of the upper space 14a in the circulation path 14. As described above, since the blower fan 28 and the evaporator 36 are disposed in the upper space 14a, the upper partition 52 is easily cooled in response to the cooling operation.

[0027] In addition, a packing P is provided along the outer peripheral edge of the rear surface of the doors 20A, 20B described above (shown by a broken line in FIG. 1), and when the doors 20A, 20B are closed, the packing P comes into contact with the upper partition 52 and the horizontal partition 53 to block the gap between the rear surface of the doors 20A, 20B and the passage opening portion 50. In addition, the packing P is not provided on the lower edge of the rear surface of the doors 20A, 20B, and instead, a thin shielding plate 38 (see FIG. 1) is disposed so as to hang down toward the bottom plate 26. In the closed state of the doors 20A, 20B, the lower edge side of the shielding plate 38 comes into contact with the bottom plate 26, and the shielding plate 38 is positioned so as to block the gap between the lower end surface of the doors 20A, 20B and the bottom plate 26 from the rear side.

[0028] (Code heater 71, 72, 73) As described above, in the disinfection storage cabinet 10, the air outside the cabinet contacts the upper partition 52 and the horizontal partition 53 through the gap between the upper end surface 61 and the side end surface 62 of the doors 20A, 20B and the outer peripheral frame 51 of the housing 12. The upper partition 52 and the horizontal partition 53 are lowered in temperature due to the effect of the cooling operation, so condensation may occur when warm air from outside the cabinet contacts them. In addition, the temperature around the bottom plate 26 of the storage room 16 is likely to drop during the cooling operation due to the nature of cold air moving downward. For this reason, condensation may occur when warm air from outside the cabinet contacts the lower end surface 64 of the doors 20A, 20B and the front part 26a of the bottom plate 26. Therefore, in the first embodiment, electric heaters for preventing condensation (heaters for preventing condensation) are installed on each of the installation targets (the upper partition 52, the left and right horizontal partitions 53, 53, and the bottom plate 26) located around the doors 20A, 20B of the housing 12. In the first embodiment, bendable linear cord heaters 71, 72, and 73 are installed at the installation targets 52, 53, and 26, respectively, as dew-prevention heaters.

[0029] As shown in Fig. 3, the cord heaters 71, 72, and 73 are an upper edge heater 71 (corresponding to the upper edge of the doors 20A and 20B) for the upper partition 52, a side edge heater 72 (corresponding to the side edge of the doors 20A and 20B) for the horizontal partition 53, and a lower edge heater 73 (corresponding to the lower edge of the doors 20A and 20B) for the front part 26a of the bottom plate 26. The upper edge heater 71 (see Fig. 4) is attached to the back surface of the front plate 52a of the upper partition 52, and the side edge heater 72 (see Figs. 4 and 5) is attached to the back surface of the front plate 53a of the horizontal partition 53. The lower edge heater 73 (see Fig. 5) is attached to the front part of the lower surface of the bottom plate 26 (the lower surface of the front part 26a). That is, the cord heaters 71, 72, 73 are disposed around the doors 20A, 20B in the housing 12 (the passage opening portion 50) and in positions adjacent to the outer peripheral end faces 61, 62, 63, 64 of the doors 20A, 20B.

[0030] In the disinfection storage cabinet 10 of the first embodiment, the heat generation amount of each cord heater 71, 72, 73 is determined in consideration of the difference in the temperature change tendency (temperature drop tendency, i.e., ease of cooling by cooling operation) during cooling operation in the installation target (upper partition 52, horizontal partition 53, bottom plate 26) of the cord heater 71, 72, 73. The cord heaters 71, 72, 73 are made of the same material and have the same thickness, but the overall heat generation amount is made different by making the total length different. Specifically, as shown in FIG. 6, a cord heater with a power consumption of 40.0 W is adopted as the upper heater 71, a cord heater with a power consumption of 28.0 W is adopted as the side heater 72, and a cord heater with a power consumption of 60.0 W is adopted as the lower heater 73. The overall lengths of the upper heater 71 are 2.5 m, the side heater 72 is 1.8 m, and the lower heater 73 is 3.8 m, which are different from each other.

[0031] Here, the upper partition 52 is the front wall of the upper space 14a as described above, and therefore the temperature is likely to decrease in response to the cooling operation. On the other hand, the horizontal partition 53 is located in front of the side space 14b, and the temperature decrease due to the cooling operation is smaller than that of the upper partition 52. Therefore, when the surface temperatures of the upper partition 52 and the horizontal partition 53 are measured during the cooling operation, the surface temperature of the upper partition 52 is lower than the surface temperature of the horizontal partition 53. That is, the upper partition 52 on which the upper heater 71 is installed and the horizontal partition 53 on which the side heater 72 is installed have different temperature change tendencies during the cooling operation. In contrast, in the disinfection storage cabinet 10 of the first embodiment, the heat generation amount of the upper heater 71 is made larger than the heat generation amount of the side heater 72 in response to the difference in the temperature change tendencies during the cooling operation in the upper partition 52 and the horizontal partition 53.

[0032] In addition, since the cold air moves downward inside the cabinet, the temperature of the bottom plate 26 located below the storage chamber 16 is more likely to drop than that of the horizontal partition 53. Therefore, when the surface temperatures of the bottom plate 26 (front part 26a) and the horizontal partition 53 are measured during cooling operation, the surface temperature of the bottom plate 26 (front part 26a) is lower than that of the horizontal partition 53. That is, the front part 26a of the bottom plate 26 on which the bottom heater 73 is installed and the horizontal partition 53 on which the side heater 72 is installed have different temperature change tendencies during cooling operation. In contrast, in the disinfection storage cabinet 10 of Example 1, the heat generation amount of the bottom heater 73 is made larger than that of the side heater 72 in accordance with the difference in the temperature change tendencies during cooling operation in the front part 26a of the bottom plate 26 and the horizontal partition 53.

[0033] In this way, in the disinfection storage cabinet 10 of the first embodiment, the cord heaters (heaters for preventing condensation) 71, 72, 73 are provided on the upper partition 52, the horizontal partition 53, and the front part 26a (multiple installation targets) of the bottom plate 26 located around the doors 20A, 20B in the housing 12, thereby preventing condensation from occurring near the boundary between the housing 12 (passage opening forming part 50) and the doors 20A, 20B. In this case, the cord heaters 71, 72, 73 with different heat values ​​are provided on the installation targets 52, 53, 26a according to the difference in the temperature change tendency of the installation targets 52, 53, 26a during the cooling operation, thereby reducing the cost of parts and the waste of power consumption.

[0034] The dimension (left-right dimension) w2 in the short side direction of the horizontal partition 53 on which the side heater 72 is to be installed is narrow, and the horizontal partition 53 is elongated in the vertical direction. Therefore, the side heater 72 is provided in a straight line (as one straight line portion 72a) extending in the longitudinal direction (up-down direction) of the horizontal partition 53. In contrast, the dimensions w1 and w3 in the short side direction of the upper partition 52 on which the upper heater 71 is to be installed and the front part 26a of the bottom plate 26 on which the lower heater 73 is to be installed are relatively large. Therefore, the upper heater 71 and the lower heater 73 are arranged such that the straight line portions 71a, 71b, 71c, 73a, 73b, 73c extending in the longitudinal direction (left-right direction) of the upper partition 52 and the front part 26a of the bottom plate 26 are lined up in the short side direction of each installation target 52, 26a.

[0035] (Upper edge heater 71 prevents condensation at the joints of doors 20A and 20B) Here, the shape and position of the above-mentioned upper edge heater 71 in the installed state will be described in more detail with reference to Figures 3 and 4. The upper edge heater 71 is composed of a first horizontal part 71a extending slightly upward along the upper end surface 61 of the doors 20A and 20B, a second horizontal part 71b and a third horizontal part 71c extending slightly downward along the upper end surface 61 of the doors 20A and 20B, a first return part 71d connecting the right ends of the first and second horizontal parts 71a and 71b, and a detouring part 71e connecting the left end of the second horizontal part 71b and the right end of the third horizontal part 71c.

[0036] Between the side end faces 63, 63 on the open end side of the left door 20A and the right door 20B, a space extending in the vertical direction (hereinafter referred to as "seam S") is formed. Here, the bypass portion 71e of the upper side heater 71 has a left vertical portion 71e1 extending in the vertical direction along the side end face 63 on the open end side of the left door 20A (along the left side of the seam S) and a right vertical portion 71e3 extending in the vertical direction along the side end face 63 on the open end side of the right door 20B (along the right side of the seam S), and the lower end of the left vertical portion 71e1 and the lower end of the right vertical portion 71e3 are connected via a second return portion 71e2 crossing the seam S.

[0037] In this way, in the disinfection storage cabinet 10 of the first embodiment, the upper edge heater 71 corresponding to the upper edges of the doors 20A and 20B has horizontal parts 71a, 71b, and 71c extending in the left-right direction along the upper end surface 61 of the doors 20A and 20B, and vertical parts 71e1 and 71e3 extending in the up-down direction along the joint S of the doors 20A and 20B, so that the heating of the horizontal parts 71a, 71b, and 71c of the upper edge heater 71 can prevent the occurrence of condensation on the surface of the upper partition 52 and the upper end surface 61 of the doors 20A and 20B. In addition, the heating of the vertical parts 71e1 and 71e3 of the upper edge heater 71 can effectively prevent condensation on the surface of the upper partition 52 and the side end surface 63 on the open end side of the doors 20A and 20B. In other words, since the upper edge heater 71 can prevent condensation around the seam S of the doors 20A, 20B, it is possible to omit the installation of a cord heater on the doors 20A, 20B (at their open ends), thereby reducing costs and preventing the manufacturing process from becoming complicated.

[0038] (Control of cord heaters 71, 72, 73) Next, referring to FIG. 7, the control of the cord heaters 71, 72, and 73 described above will be described. As shown in FIG. 7(a), the control means 100 provided in the disinfection storage cabinet 10 is electrically connected to the electric heater 30, the fan motor 29, the damper 34, and the refrigeration mechanism R. Then, in the disinfection operation for disinfecting the stored items in the storage room 16, the electric heater 30 and the fan motor 29 are operated while maintaining the closed state of the exhaust duct 32 (the damper 34 is in the off state). Also, in the drying operation for drying the disinfected stored items, the damper 34 is turned on to open the exhaust duct 32 while continuing the operating state of the electric heater 30 and the fan motor 29. Then, after the disinfection / drying operation is completed, the refrigeration mechanism R is controlled to perform a cooling operation for cooling the inside of the storage room 16 (the stored items) in a high temperature state. Here, the control means 100 is electrically connected to the upper side heater 71, the side side heater 72, and the lower side heater 73 described above, and the inside temperature sensor 101 for detecting the inside temperature.

[0039] The dew point under the harshest conditions (specifically, an environment of 70% relative humidity and 35°C room temperature) assumed as the use environment of the disinfection storage cabinet 10 of the first embodiment is 28.7°C. The housing 12 of the disinfection storage cabinet 10 has a heat insulating performance such that when the inside temperature detected by the inside temperature sensor 101 during the cooling operation after the disinfection and drying operation drops to 20°C, the surface temperature of the upper partition 52 (front plate 52a) on which the above-mentioned top heater 71 is installed becomes about 30°C (a temperature slightly higher than the dew point temperature). The horizontal partition 53 and the bottom plate 26 (front part 26a) on which the above-mentioned side heater 72 and bottom heater 73 are installed maintain a surface temperature higher than 30°C when the inside temperature becomes 20°C. That is, even in a severe usage environment, the disinfection storage cabinet 10 is unlikely to cause condensation on the upper partition 52, the horizontal partition 53, and the front part 26a of the bottom plate 26 until the temperature inside the cabinet falls below 20°C (a specific temperature higher than the temperature that reduces the surface temperature of the upper partition 52 to the dew point temperature). Therefore, the control means 100 does not operate the upper edge heater 71, the side edge heater 72, and the lower edge heater 73 from the start of the cooling operation, but operates them in response to the temperature inside the cabinet decreasing to a specific temperature (20°C).

[0040] As shown in FIG. 7(b), when the control means 100 starts the cooling operation (step S1), it monitors the inside temperature detected by the inside temperature sensor 101. Then, it determines whether the inside temperature has dropped to a specific temperature (20°C) (step S2). In this case, if the inside temperature has dropped to the specific temperature, it activates the top-side heater 71, the side-side heater 72, and the bottom-side heater 73, which have been kept in an inactive state (step S3). Then, when it is time to end the cooling operation (when an operation end operation is performed, etc.) (step S4), it ends the cooling operation (step S5).

[0041] In this way, the control means 100 of the disinfection storage cabinet 10 operates the upper edge heater 71, the side edge heater 72, and the lower edge heater 73 in response to the temperature inside the cabinet dropping during the cooling operation and reaching a specific temperature of 20°C, so that the operating time of the upper partition 52, the horizontal partition 53, and the front part 26a of the bottom plate 26 can be shortened to suppress the power consumption during the operation of the disinfection storage cabinet 10, and the efficiency of cooling inside the cabinet is not excessively reduced. Note that the specific temperature in the cabinet is higher than the temperature at which the upper partition 52 (front plate 52a) reaches the dew point temperature, so that the occurrence of condensation on the upper partition 52 can be sufficiently suppressed. Similarly, the specific temperature in the cabinet is higher than the temperature at which the horizontal partition 53 (front plate 53a) and the front part 26a of the bottom plate 26 reach the dew point temperature, so that the occurrence of condensation on the upper partition 52 and the front part 26a of the bottom plate 26 can be sufficiently suppressed.

[0042] (1st to 3rd insulators 91, 92, 93) Next, the condensation prevention configuration (anti-condensation measures other than those for the cord heaters 71, 72, and 73) provided on the doors 20A and 20B will be described with reference to Figures 8 and 9. The schematic configuration of the left door 20A and the right door 20B will be described first, and then the first to third heat insulators 91, 92, and 93 will be described.

[0043] 8, the left door 20A and the right door 20B are configured into a box shape using a plurality of metal plates 65, 66, 67, and a heat insulating material 69 is disposed in the internal space. A right inner plate (target portion) 81 into which a screw portion 86 of a first fixing member 83 (described later) is screwed is disposed at each open end of the left door 20A and the right door 20B, and a left inner plate (target portion) 82 into which a screw portion 86 of a second fixing member 84 (described later) is screwed is disposed at each shaft side end of the left door 20A and the right door 20B.

[0044] At the open end of the left door 20A, a partition piece 70 that extends in the vertical direction and closes the joint S of the doors 20A and 20B from the inside of the cabinet is formed by the metal plate 67 of the doors 20A and 20B. The partition piece 70 is composed of a first extension part 70a that extends toward the inside of the cabinet and a second extension part 70b that extends from the first extension part 70a toward the right (toward the right door 20B). That is, the joint S is located on the front side of the second extension part 70b, and the storage room 16 is located on the back side. Since the packing P is provided at the open end of the right door 20B so as to extend in the vertical direction, when the right door 20B is closed with the left door 20A closed, the packing P of the right door 20B comes into contact with the right end part of the partition piece 70.

[0045] The temperature of the metal plate 66 forming the back surface of the doors 20A, 20B facing the storage room 16 drops during cooling operation. When the components of the doors 20A, 20B (for example, the metal plate 65) and the internal space of the doors 20A, 20B cool due to the influence of the metal plate 66, condensation may occur on the outer surfaces of the doors 20A, 20B exposed to the outside of the storage room. In addition, condensation may occur on the parts of the metal plates 65, 66 located around the joint S (the right end of the metal plate 65 and the partition piece 70 of the metal plate 67) due to contact with the warm air outside the storage room that flows into the joint S of the doors 20A, 20B. To cope with this, first to third heat insulators 91, 92, 93 for preventing condensation are installed at appropriate positions on the left door 20A and the right door 20B.

[0046] The first heat insulator 91 (see Figs. 1 and 8) is a plate-like member made of synthetic resin material, and is provided on the outer surfaces of the open end side and the lower end side of the metal plate 65 of the left door 20A and the right door 20B, respectively, to form the side end surface 63 of the open end side and the lower end surface 64 of the doors 20A, 20B. The second heat insulator 92 (see Fig. 8) is a sheet-like member made of a material (e.g., silicon) that can withstand high temperatures during disinfection and drying operation and low temperatures during cooling operation, and is provided on the outer peripheral edge of the surface of the metal plate 66 of the left door 20A and the right door 20B, respectively. The third heat insulator 93 (see Figs. 1 and 8) is a plate-like member made of synthetic resin material, a part of which is fixed to the inner side of the open end of the left door 20A, and another part of which covers the partition piece 70 of the left door 20A. It should be noted that a hard material (synthetic resin) is selected for the first heat insulator 91 and the third heat insulator 93, taking into consideration that they will be exposed to the outside.

[0047] As shown in FIG. 8, the first heat insulator 91 and the third heat insulator 93 are fixed to the right inner plate 81 by the first fixing member 83 at the open end of the door 20A, 20B. The first fixing member 83 is a screw member having a head 85 at one end in the longitudinal direction and a threaded portion 86 at the other end. However, as is clear from the enlarged view in FIG. 8, a fitting portion 87 having a diameter larger than that of the threaded portion 86 and smaller than that of the head 85 is provided between the head 85 and the threaded portion 86. Here, the first heat insulator 91 is provided with a plurality of long fitting holes 91a (see FIG. 9(a)) extending in the longitudinal direction (up-down direction) at positions spaced apart in the longitudinal direction of the first heat insulator 91. The fitting holes 91a are provided with a width (see FIG. 8) smaller than the diameter of the head 85 of the first fixing member 83 and slightly larger than the diameter of the fitting portion 87. The third insulator 93 has circular fitting holes 93a (see FIG. 8) provided at a plurality of locations spaced apart in the longitudinal direction of the third insulator 93. The fitting holes 93a are provided with a diameter smaller than the diameter of the head 85 of the first fixing member 83 and slightly larger than the diameter of the fitting portion 87 (see FIG. 8). The first insulator 91 and the third insulator 93 are fixed in a state in which the screw portion 86 of the first fixing member 83 is screwed into the right inner plate 81, and the fitting portion 87 is positioned between the right inner plate 81 and the head 85, with the fitting portion 87 fitted into the inside of the fitting holes 91a, 93a.

[0048] Similarly to the first fixing member 83, the second fixing member 84 is a screw member having a head 85 at one end in the longitudinal direction and a threaded portion 86 at the other end, and a fitting portion 87 having a diameter larger than the threaded portion 86 and smaller than the head 85 is provided between the head 85 and the threaded portion 86. The second heat insulator 92 is provided with circular fitting holes 92a having a diameter smaller than the diameter of the head 85 of the second fixing member 84 and slightly larger than the diameter of the fitting portion 87 at a plurality of locations spaced apart in the longitudinal direction of the second heat insulator 92 (see FIG. 8). With the threaded portion 86 of the second fixing member 84 screwed into the left inner plate 82, the second heat insulator 92 is positioned between the left inner plate 82 and the head 85, and is fixed with the fitting portion 87 fitted inside the fitting hole 92a.

[0049] In this way, in the disinfection storage cabinet 10 of the first embodiment, the first fixing member 83 and the second fixing member 84 hold the heat insulators 91, 92, 93 in a space corresponding to the dimension of the fitting portion 87 provided between the screw portion 86 and the head portion 85, so that the head portion 85 of the fixing members 83, 84 does not strongly press the heat insulators 91, 92, 93 to deform them. Therefore, it is possible to prevent the screw portion 86 from loosening due to the restoring force of the heat insulators 91, 92, 93 that are pressed and deformed by the head portion 85 of the fixing members 83, 84, and the rigidity of the doors 20A, 20B can be maintained. In addition, by making the fitting hole 91a of the first heat insulator 91 an elongated hole extending in the longitudinal direction of the first heat insulator 91, the fixing state by the first fixing member 83 can be well maintained even if the first heat insulator 91 shrinks or warps due to temperature changes or the like. Furthermore, by sandwiching a sheet-like second insulation body 92 between the metal plate 66 forming the back surface of the doors 20A, 20B and the left inner panel 82 and arranging the sheet-like insulation body 92 along the surface of the metal plate 66, it is possible to prevent condensation from forming on the surfaces of the doors 20A, 20B.

[0050] As shown in Fig. 8, the left end of the metal plate 65 forming the surface of the left door 20A is bent in a U-shape in cross section, so that a part of it forms the side end surface 62 on the shaft side of the left door 20A and a part of it forms the side edge of the back surface of the left door 20A. At the outer peripheral edge of the left door 20A, the metal plates 65 and 66 overlap each other front to back. Meanwhile, the second heat insulator 92 is fixed to the left inner plate 82 by the second fixing member 84 in a state where it is sandwiched between the metal plates 65 and 66 at the outer peripheral edge of the left door 20A. Although not shown, the right door 20B is similar.

[0051] That is, in the disinfection storage cabinet 10 of the first embodiment, a second heat insulator 92 is interposed between the metal plate 66 forming the back surface of the doors 20A, 20B and the metal plate (another component) 65 forming the front surface of the doors 20A, 20B, and is disposed along the outer periphery of the doors 20A, 20B. This makes it possible to prevent a temperature drop of the metal plate 65 due to contact with the metal plate 66 forming the back surface of the doors 20A, 20B, and to suppress the occurrence of condensation on the doors 20A, 20B.

[0052] 8 and 9, the third heat insulator 93 is provided with a fixed plate portion 94 whose plate thickness direction is the left-right direction when the left door 20A is in the closed state, and a covering plate portion 95 whose plate thickness direction is the front-rear direction when the left door 20A is in the closed state. The fixed plate portion 94 is inserted into the open end portion of the left door 20A from the back side, and is fixed between the right end portion of the metal plate 65 of the left door 20A and the right inner plate 81 arranged on the inside of the left door 20A. The covering plate portion 95 extends rightward from the back end portion of the fixed plate portion 94 along the second extending portion 70b of the partition piece 70, and covers the surface of the second extending portion 70b (except for the right end portion with which the packing P of the right door 20B comes into contact).

[0053] In this way, the disinfection storage cabinet 10 of the first embodiment can prevent condensation on the partition piece 70 with an inexpensive structure by positioning the third heat insulator 93 (covering plate portion 95) between the partition piece 70 of the left door 20A and the seam S. The third heat insulator 93 (covering plate portion 95) is positioned to avoid the right end portion of the second extension portion 70b of the partition piece 70 with which the packing P of the right door 20B comes into contact, so that a space for the packing P is secured between the surface of the partition piece 70 and the back surface of the right door 20B, and no extra force is applied by the operator when the right door 20B is closed with the left door 20A closed. In addition, by positioning the fixing plate portion 94 of the third heat insulator 93 extending in the vertical direction inside the open end portion of the left door 20A, it is possible to prevent the air at the seam S from being cooled due to the effect of a temperature drop inside the left door 20A. EXAMPLES

[0054] Next, the disinfection storage cabinet 10 according to the second embodiment will be described below with reference to FIG. 10. The configurations different from those of the first embodiment will be basically described, and the same configurations as those of the first embodiment will be denoted by the same reference numerals and detailed description will be omitted. In the first embodiment described above, the side heater 72 of the horizontal partition 53 is a single straight line. In contrast, the disinfection storage cabinet 10 of the second embodiment has the side heater 72 installed on the horizontal partition 53 in a shape different from that of the first embodiment, and is otherwise the same as the first embodiment. Therefore, in the second embodiment, the installation state of the side heater 72 will be described.

[0055] When the disinfection storage cabinet 10 performs a cooling operation, condensation may occur on the side end surface 62 on the shaft side of the doors 20A and 20B and the side frame plate 51S of the housing 12 (passage forming portion 50). However, if a cord heater other than the side heater 72 is prepared and directly installed on the side frame plate 51S, the number of cord heaters increases, which increases the cost and requires a lot of work to install. Therefore, in the second embodiment, one cord heater (side heater 72) is folded back into a U-shape, and in addition to the vertical portion 72a extending in the vertical direction at a position aligned with the packing P of the doors 20A and 20B, a second vertical portion 72b extending in the vertical direction parallel to the vertical portion 72a is provided, and the second vertical portion 72b prevents condensation from occurring on the side frame plate 51S.

[0056] The second vertical portion 72b may be attached to the left side surface of the side frame plate 51S as the installation target surface. However, in this case, the side heater 72 is likely to float at the corner between the front plate 53a of the horizontal partition 53 and the side frame plate 51S, making it difficult to maintain the installation state of the side heater 72 in a good condition. Therefore, in the disinfection storage cabinet 10 of the second embodiment, the second vertical portion 72b is attached to the same installation target surface (the back surface of the front plate 53a of the horizontal partition 53) as the first vertical portion 72a so as to extend in a position aligned with the side frame plate 51S in the front-rear direction.

[0057] Therefore, when the side heater 72 is operated under the control of the control means 100 during cooling operation, the front plate 53a of the horizontal partition 53 is sufficiently heated by the first vertical portion 72a and the second vertical portion 72b of the side heater 72. In addition, the side frame plate 51S is efficiently heated by the second vertical portion 72b, and the side end faces 62 on the shaft side of the doors 20A, 20B are heated by heat radiation from the side frame plate 51S, thereby effectively preventing condensation around the side end faces 62.

[0058] That is, in the disinfection storage cabinet 10 of the second embodiment, during cooling operation, the first vertical portion 72a of the side heater 72 can effectively prevent condensation on the horizontal partition 53, etc., by heating, and the second vertical portion 72b of the side heater 72 can effectively prevent condensation on the side frame plate 51S and the side end surface 62 on the axis side of the doors 20A, 20B. Here, the side heater 72 is disposed so that the first and second vertical portions 72a, 72b are along the same plane of the horizontal partition 53 (the back surface of the front plate 53a of the horizontal partition 53), so that the installation work of the side heater 72 is not complicated, and the installation state can be prevented from becoming unstable. EXAMPLES

[0059] Next, the disinfection storage cabinet 10 according to the third embodiment will be described below with reference to Figs. 12 and 13. The configurations different from those of the first and second embodiments will be basically described, and the same configurations as those of the first and second embodiments will be given the same reference numerals and will not be described in detail. In the first embodiment described above, the fitting holes 91a provided at a plurality of positions spaced apart in the longitudinal direction of the first insulator 91 are elongated along the longitudinal direction of the first insulator 91 to allow deformation (warping, etc.) of the first insulator 91 due to temperature changes, etc. In contrast, the third embodiment includes a deformation suppressing means for suppressing deformation of the first insulator 91, and therefore the configuration for suppressing deformation of the first insulator 91 will be mainly described in the third embodiment. The first insulator 91 includes one that covers the open end sides of the doors 20A, 20B and one that covers the bottom end sides of the doors 20A, 20B (similar to the above-mentioned Example 1). However, since these have the same structure in terms of the deformation prevention means, the following description will focus on the first insulator 91 that covers the open end side of the left door 20A.

[0060] As shown in Figs. 12 and 13, in the third embodiment, a double-sided tape (adhesive means) 111 is interposed between the first heat insulator 91 and the left door 20A (metal plate 65) as a deformation prevention means. That is, in a state where the opposing surfaces of the first heat insulator 91 and the metal plate 65 are adhered to each other, the first fixing members 83 are inserted into the fitting holes 91a to fix the first heat insulator 91 at a plurality of locations, thereby attaching the first heat insulator 91 to the left door 20A. As a result, the first heat insulator 91 is reinforced by the metal plate 65, and deflection deformation caused by temperature changes and the like is suppressed, so that a gap is unlikely to occur between the first heat insulator 91 and the metal plate 65 (left door 20A). In addition, by suppressing deflection deformation of the first heat insulator 91, the first fixing member 83 is unlikely to loosen. Therefore, the effect of preventing condensation by the first heat insulator 91 can be maintained. Although each fitting hole 91a of the first heat insulator 91 is formed in a circular shape (not shown), it may be formed in an elongated hole shape similar to the first embodiment described above.

[0061] 13, the double-sided tape 111 is disposed so as to correspond to a range x2 between the fixing positions of the uppermost and lowermost first fixing members 83 within a range x1 from the uppermost to the lowermost ends of the first heat insulator 91. That is, even if the upper end side of the first heat insulator 91 (the side x3 above the uppermost first fixing member 83) and the lower end side of the first heat insulator 91 (the side x4 below the lowermost first fixing member 83) expand due to a temperature change, they are not sandwiched in the fixing positions of the first fixing members 83 and are therefore unlikely to bend or deform. Therefore, the range excluding the upper end side and the lower end side of the first heat insulator 91 is adhered to the left door 20A (sheet metal 65) with the double-sided tape 111, thereby eliminating wasted dimensions of the double-sided tape 111. EXAMPLES

[0062] Next, the disinfection storage cabinet 10 according to the fourth embodiment will be described below with reference to FIG. 14. The configurations different from those of the first to third embodiments will be basically described, and the same configurations as those of the first to third embodiments will be given the same reference numerals and detailed description will be omitted. In the fourth embodiment, the shape of the partition piece 70 (second extension portion 70b) is different from that of the first embodiment described above, and the fourth embodiment also differs from the first embodiment in that it includes a sealing member 113 described later. Therefore, in the fourth embodiment, the partition piece 70 (second extension portion 70b) and the sealing member 113 will be mainly described.

[0063] As described in the first embodiment, a packing P is provided on the back surface of the open end of the right door 20B, and when the right door 20B is closed while the left door 20A is closed, the packing P of the right door 20B comes into contact with the metal partition piece 70 provided on the open end of the left door 20A. Here, the partition piece 70 of the fourth embodiment has a bent second extension portion 70b to enhance adhesion with the packing P. Specifically, as shown in FIG. 14(a), the second extension portion 70b of the partition piece 70 is composed of an extension base portion 70b1 extending from the first extension portion 70a in parallel with the back surface of the left door 20A (toward the right in the closed state), and an inclined portion 70b2 extending obliquely from the extension end of the extension base portion 70b1 to the front side.

[0064] As shown in Fig. 14(a), the second extending portion 70b of the partition piece 70 is bent so that the surfaces of the extending base portion 70b1 and the inclined portion 70b2 form an obtuse angle. That is, the inclined portion 70b2 of the second extending portion 70b is formed so as to be gradually spaced apart from the first extending portion 70a toward the extending end side. The extending dimension of the inclined portion 70b2 is set to a dimension that the inclined portion 70b2 does not come into contact with the right door 20B even when both doors 20A and 20B are closed.

[0065] Here, when the right door 20B is closed while the left door 20A is closed, the packing P is sandwiched between the partition piece 70 and the open end of the right door 20B as shown in FIG. 14(b). In this case, the packing P is crushed in the thickness direction of the right door 20B by contact with the extension base portion 70b1 of the partition piece 70, but is received by the inclined portion 70b2 of the partition piece 70 and deformation to the right is restricted. Therefore, when the right door 20B is closed, the packing P is in contact with the extension base portion 70b1 and the inclined portion 70b2. That is, by providing the inclined portion 70b2 on the partition piece 70 (second extension portion 70b), the range in which the packing P can deform is narrowed, the contact area between the packing P and the partition piece 70 is increased, and the airtightness of the interior of the container is improved.

[0066] As shown in FIG. 14(a), a seal member 113 that elastically contacts a portion of the back surface of the right door 20B that is closer to the axis than the packing P is provided on the extension end side of the second extension portion 70b of the partition piece 70. The seal member 113 is made of a soft resin material or a rubber material, and is fixed by a screw member N by overlapping it on the back surface of the inclined portion 70b2 of the partition piece 70. The vertical dimension of the seal member 113 is set according to the vertical dimension of the partition piece 70. Here, the left end side of the seal member 113 overlaps with the inclined portion 70b2 of the partition piece 70, and the right end side extends toward the front side more than the inclined portion 70b2. Since the inclined portion 70b2 is inclined with respect to the extension base portion 70b1, the seal member 113 that is attached by overlapping it on the back surface of the inclined portion 70b2 is also inclined with respect to the extension base portion 70b1. 14(b), when the right door 20B is closed, the right end side of the seal member 113 elastically deforms due to contact with the right door 20B and comes into close contact with the rear surface of the right door 20B (the portion closer to the axis than the packing P). That is, the seal member 113, in addition to the packing P, seals the space between the partition piece 70 and the right door 20B, improving the airtightness between the open ends of the doors 20A and 20B.

[0067] The closed state of the doors 20A and 20B is maintained by the engagement between the latch 112 (see FIG. 14) of the right door 20B and the latch receiver (not shown) on the housing 12 side. That is, when the right door 20B is closed with the left door 20A closed, the right door 20B is pushed toward the passage 50a of the housing 12 until the latch 112 engages with the latch receiver. Here, the latch receiver is concave, and if it is provided on the lower edge side of the passage 50a (the bottom plate 26 of the housing 12), it may accumulate dust and become unsanitary. Therefore, the latch 112 is provided only on the upper end surface 61 of the right door 20B of the disinfection storage cabinet 10, and the latch receiver is provided only on the upper frame plate 51T of the housing 12 (the upper edge side of the passage 50a). Therefore, when the right door 20B is closed, the lower end side of the open end of the right door 20B without the latch 112 is pushed back slightly to the front side by the restoring force (reaction force) of the packing P, etc., and the adhesion between the partition piece 70 and the packing P is weakened. In response to this situation, by providing the inclined portion 70b2 on the partition piece 70 and attaching the seal member 113 as described above, sufficient sealing can be achieved even when the locking structure by the latch 112 and the latch receiver is provided only on the upper side of the right door 20B (passage opening 50a). Note that if the locking structure is provided on both the upper and lower sides of the right door 20B (passage opening 50a), the partition piece 70 and the packing P can be brought into close contact, but in addition to the hygiene problem described above, there are problems such as an increase in the number of parts and an increase in the pushing force required to close the right door 20B. EXAMPLES

[0068] Next, the disinfection storage cabinet 10 according to the fifth embodiment will be described below with reference to FIG. 15. The configurations different from those of the first to fourth embodiments will be basically described, and the same configurations as those of the first to fourth embodiments will be given the same reference numerals and detailed description will be omitted. In the fifth embodiment, the protruding dimension of the seal member 114 toward the inside (back side) of the cabinet is increased to change the air flow from the inside of the cabinet toward the partition piece 70 side. Therefore, in the fifth embodiment, the seal member 114 will be described mainly with respect to the differences from the seal member 113 of the fourth embodiment.

[0069] As shown in FIG. 15, in the fifth embodiment, the seal member 114 is fixed at an approximately central position to the inclined portion 70b2 of the partition piece 70 by the screw member N. The right end side (one end side in the width direction) of the seal member 114 elastically contacts with a portion of the back surface of the right door 20B that is closer to the shaft than the packing P, and the left end side (the other end side in the width direction) is located on the inside (back side) of the cabinet than the extension base portion 70b1 of the partition piece 70. The width dimension w1 of the portion of the seal member 114 on the left end side of the fixing position by the screw member N is larger than the diameter dimension of the head Na of the screw member N. By configuring the seal member 114 in this way, during the cooling operation of the disinfection storage cabinet 10, the cold air that tries to move from the inside of the cabinet toward the right along the back surface of the left door 20A and the back surface of the partition piece 70 (the second extension portion 70b) is stagnated in the area between the extension base portion 70b1 and the seal member 114 (flows in the direction of the arrow Y1 in FIG. 15). Also, the path of cold air moving leftward along the back surface of the right door 20B from the inside of the cabinet is blocked, and the cold air is guided by the seal member 114 to the side away from the second extension portion 70b (the direction of the arrow Y2 in FIG. 15). That is, the seal member 114 in the fifth embodiment is configured to extend the portion to the left of the fixing position by the screw member N toward the inside of the cabinet, thereby changing the flow of air along the back surface of the doors 20A, 20B during the cooling operation, making it difficult for the partition piece 70 to be cooled. Therefore, when the cooling operation is performed, it is possible to suppress the occurrence of condensation due to a drop in temperature of the partition piece 70. Also, it is possible to improve the airtightness of the cabinet, improve the cooling capacity during the cooling operation, and improve the heating capacity during the disinfection and drying operation. EXAMPLES

[0070] Next, the disinfection storage cabinet 10 according to the sixth embodiment will be described below with reference to Fig. 16. The configurations different from those of the first to fifth embodiments will be basically described, and the same configurations as those of the first to fifth embodiments will be given the same reference numerals and detailed description will be omitted. In the sixth embodiment, a cover part 117 is provided for the sealing member 115 to cover the head Na of the screw member N from the inside of the cabinet. Therefore, in the sixth embodiment, the configuration of the sealing member 115 will be mainly described.

[0071] 16, the seal member 115 of the sixth embodiment is composed of a first flexible plate 116 extending along the back surface of the inclined portion 70b2 of the partition piece 70, and a cover portion 117 covering the head Na of the screw member N from the inside of the container. The cover portion 117 is composed of an upright portion 117a rising substantially vertically from the back surface of the first flexible plate 116, and a second flexible plate 117b extending substantially parallel to the first flexible plate 116 from the extending end of the upright portion 117a, and the upright portion 117a is located closer to the inside of the container (back side) than the screw member N. The first flexible plate 116 and the second flexible plate 117b of the cover portion 117 are spaced apart in the plate thickness direction by the extending dimension of the upright portion 117a, and the head Na of the screw member N is located in the space corresponding to this distance. Moreover, the first flexible plate 116 and the second flexible plate 117b have substantially the same extension dimension on the front side from the standing portion 117a.

[0072] Here, the first flexible plate 116 and the second flexible plate 117b extend to a position where they come into contact with the back surface of the right door 20B when the right door 20B is in a closed state. Therefore, when the right door 20B is closed, the first flexible plate 116 first comes into contact with the right door 20B and elastically deforms, and when the right door 20B is further moved in the closing direction, the second flexible plate 117b comes into contact with the right door 20B and elastically deforms. As a result, both the first flexible plate 116 and the second flexible plate 117b come into close contact with the back surface of the right door 20B. That is, the seal member 115 of the sixth embodiment includes a plurality of parallel flexible plates 116, 117b spaced apart in the plate thickness direction, and the right end side (one end side in the width direction) of each of the flexible plates 116, 117b is configured to elastically come into contact with a portion of the back surface of the right door 20B that is closer to the shaft than the packing P. In this way, by bringing the multiple flexible plates 116, 117b provided on the sealing member into contact with the right door 20B, the airtightness between the open ends of both doors can be improved compared to a single plate-shaped member such as the sealing members 113, 114 of the above-mentioned embodiments 4 and 5.

[0073] Furthermore, by providing the cover portion 117 to the seal member 115, the cold air (air flowing in the direction of the arrow Y4 in FIG. 16) moving from the inside of the cabinet toward the second extension portion 70b of the partition piece 70 during the cooling operation of the disinfection storage cabinet 10 is less likely to come into contact with the first flexible plate 116. In particular, the path of the cold air moving from the right side of the cabinet toward the second extension portion 70b of the partition piece 70 is blocked, and the cold air is guided by the seal member 115 to the side away from the second extension portion 70b. In addition, since the first flexible plate 116 protrudes farther toward the inside of the cabinet (back side) than the second extension portion 70b of the partition piece 70, the presence of the first flexible plate 116 causes the flow of air moving from the left side of the cabinet toward the periphery of the back side of the second extension portion 70b to be impeded (arrow Y3 in FIG. 16). That is, when the cooling operation is performed, the temperature drop of the partition piece 70 can be suppressed, and condensation can be prevented. In addition, the cooling capacity during cooling operation and the heating capacity during disinfection and drying operation can be improved. Furthermore, by covering the head Na of the screw member N with the cover part 117, it is possible to prevent the worker from injuring his / her fingers due to contact with the screw member B during work. From the viewpoint of preventing injury to the worker, it is preferable to combine the screw member N with a cap nut. EXAMPLES

[0074] Next, the disinfection storage cabinet 10 according to the seventh embodiment will be described below with reference to FIG. 17. The configurations different from those of the first to sixth embodiments will be basically described, and the same configurations as those of the first to sixth embodiments will be given the same reference numerals and will not be described in detail. In the first embodiment described above, the description of the specific shape of the shielding plate 38 provided at the lower end of the doors 20A and 20B will be omitted. Therefore, in the seventh embodiment, the shape of the shielding plate 38 will be described in detail. In the seventh embodiment, an auxiliary shielding plate 120 is additionally provided, and the auxiliary shielding plate 120 will also be described. The partition piece 70 is provided with the same seal member 115 as that of the sixth embodiment described above.

[0075] As shown in Fig. 17, the shielding plate 38 is disposed at the lower end of the rear surface of each of the doors 20A and 20B, respectively, and is configured to close the gap between the doors 20A and 20B and the bottom plate 26 of the housing 12. The shielding plate 38 is made of a soft resin material or a rubber material, and is fixed to the lower edge of the rear surface of the doors 20A and 20B by the screw members N. The shielding plate 38 is configured of a first flexible plate 118 that hangs down along the rear surface of the doors 20A and 20B, and a cover portion 119 that covers the head Na of the screw member N that fixes the first flexible plate 118 to the rear surface of the doors 20A and 20B. The cover portion 119 is configured of an upright portion 119a that extends from the upper edge of the first flexible plate 118 toward the interior of the fridge, and a second flexible plate 119b that is perpendicular to the upright portion 119a, and the upright portion 119a is located above the screw members N. That is, the first flexible plate 118 and the second flexible plate 119b of the cover part 119 are spaced apart by the extension dimension of the upright part 119a, and the head Na of the screw member N is located in the space of this distance. Each of the flexible plates 118, 119b extends below the height position of the bottom plate 26 of the housing 12. That is, the shielding plate 38 is configured such that, when the doors 20A, 20B are closed, each of the flexible plates 118, 119b bends and comes into close contact with the bottom plate 26, thereby doubly blocking the gap between the lower end surface 64 of the doors 20A, 20B and the bottom plate 26. Reference numeral 129 denotes a support metal fitting for maintaining the shape of the shielding plate 38.

[0076] Here, the upper end side of the second flexible plate 119b extends upward relative to the standing portion 119a, and to some extent prevents the air inside the cabinet during the cooling operation from entering between the rear surfaces of the doors 20A, 20B and the upper edge of the shielding plate 38. However, some of the air flowing downward along the rear surfaces of the doors 20A, 20B may be guided to a portion of the shielding plate 38 that is above the standing portion 119a and may flow between the rear surfaces of the doors 20A, 20B and the upper edge of the shielding plate 38 (first flexible plate 118). Therefore, in the seventh embodiment, an auxiliary shielding plate 120 is provided above the shielding plate 38 to cover the gap between the upper edge (outer edge) of the shielding plate 38 and the doors 20A, 20B. As shown in Fig. 17, the auxiliary shielding plate 120 is formed with a width dimension that matches the shielding plate 38, and is attached to the back surface of the doors 20A, 20B so as to cover the upper end side of the second flexible plate 119b that protrudes upward from the standing portion 119a. In this way, the shielding plate 38 prevents the air inside the cabinet from flowing out through the gap between the lower end of the doors 20A, 20B and the bottom plate 26, and the auxiliary shielding plate 120 prevents the air inside the cabinet from flowing out through the gap between the upper edge of the shielding plate 38 and the back surface of the doors 20A, 20B, thereby suppressing the occurrence of condensation due to a decrease in temperature of the lower end surface 64 of the doors 20A, 20B and the bottom plate 26 when a cooling operation is performed. In addition, the cooling capacity during the cooling operation and the heating capacity during the disinfection and drying operation can be improved.

[0077] A common member having the same shape may be used for two or more of the shielding plate 38, the auxiliary shielding plate 120, and the seal member 115. In this case, since the positions of the screw holes to be used are different between the shielding plate 38 and the seal member 115 and the auxiliary shielding plate 120, a member having screw holes formed in both the first flexible plate 116 (second flexible plate 119b) and the second flexible plate 117b (first flexible plate 118) may be used as the common member, and unused screw holes may be filled with another member. In addition, the shape of the shielding plate 38 may be a shape in which the portion of the second flexible plate 119b below the rising portion 119a is eliminated (crank-shaped in cross section). EXAMPLES

[0078] Next, the disinfection storage cabinet 10 according to the eighth embodiment will be described below with reference to FIG. 18. The configurations different from those of the first to seventh embodiments will be basically described, and the same configurations as those of the first to seventh embodiments will be given the same reference numerals and will not be described in detail. In the first embodiment described above, in consideration of the fact that condensation is likely to occur on the outer peripheral end faces 61, 62, 63, 64 of the doors 20A and 20B and their surroundings, the cord heaters (heaters for preventing condensation) 71, 72, 73 are installed on the passage forming portion 50 (upper partition 52, horizontal partition 53, front part 26a of the bottom plate 26) that forms the passage 50a of the housing 12. In contrast, the eighth embodiment includes a cord heater 124 for preventing condensation from occurring on the outer surface of the housing 12. Therefore, in the eighth embodiment, the configuration related to the cord heater 124 for preventing condensation from occurring on the outer surface of the housing 12 will be mainly described. The installation of at least one of the cord heaters 71, 72, 73 described in the first embodiment may be omitted.

[0079] As shown in FIG. 18, at the lower corner of the disinfection storage cabinet 10, the lower end of the partition plate 121 that defines the circulation path 14 in the cabinet and the lower end of the reinforcing plate 123 that reinforces the partition plate 121 are overlapped on the left and right, and the lower end of the reinforcing plate 123 is bent horizontally to be overlapped on the lower end of the side panel 122 that forms the outer surface of the housing 12, and are fastened together by a screw member N. Therefore, when the cold air caused by the cooling operation circulates through the circulation path 14 to cool the partition plate 121, the side panel 122 is gradually cooled from the lower end side due to the influence, and condensation may occur on the outer surface. Therefore, in the eighth embodiment, a cord heater (heater for preventing condensation) is installed at the lower end of the inner surface of the side panel 122. Hereinafter, this cord heater will be described as a "side heater 124".

[0080] The side heater 124 is attached to the lower end of the inner surface of the side panel 122, and is composed of two straight parts 124a, 124a in the front-rear direction and a folded part 124b connecting the rear ends of the straight parts 124a, 124a. That is, the side heater 124 is disposed so as to extend horizontally along the lower edge of the side panel 122 as a whole. Note that appropriate specifications (length and heat generation amount) of the side heater 124 are selected in consideration of the temperature change tendency during cooling operation of the side panel 122 on which the side heater 124 is installed, and as a result, a cord heater having a different length and heat generation amount from at least one of the other cord heaters 71, 72, 73 is adopted. Also, the side heater 124 is controlled by the control means 100 in the same way as the other cord heaters 71, 72, 73 during cooling operation (i.e., it is operated at a timing after the start of the cooling operation).

[0081] By providing side heater 124 along the lower edge of the inner surface of side panel 122 in this manner, condensation on the lower part of the side surface of housing 12 can be prevented. EXAMPLES

[0082] Next, the disinfection storage cabinet 10 according to the 9th embodiment will be described below with reference to FIG. 19. In the 9th embodiment, a connecting machine 125 consisting of two disinfection storage cabinets 10 will be described. The two disinfection storage cabinets 10 constituting the connecting machine 125 are basically of the same structure (cart-in type) as the disinfection storage cabinet 10 of the 1st embodiment, but an opening (hereinafter referred to as "communication opening 125a") is formed on the back surface where they are connected to each other so that a cart can be moved from one storage room 16 to the other storage room 16. In the 9th embodiment, the connecting structure of the two disinfection storage cabinets 10 will be basically described, and the specific configurations of the disinfection storage cabinets 10 will be assigned the same reference numerals as those in the 1st to 8th embodiments, and detailed descriptions thereof will be omitted.

[0083] As shown in FIG. 19(a), the connecting machine 125 is constructed by connecting the backs of two disinfection storage cabinets 10, and the storage chambers 16 are connected to each other by a communication port 125a formed on the backs to form one storage space 125b. Here, if the backs of the two disinfection storage cabinets 10 are completely flat, the sealed storage space 125b can be formed by simply facing the backs of both disinfection storage cabinets 10 and fastening them to each other with bolts and nuts. However, in reality, it is very difficult to make the backs of each disinfection storage cabinet 10 completely flat. That is, a gap is generated between the opposing surfaces (backs) of the two disinfection storage cabinets 10 to be connected, so that the storage space 125b of the connecting machine 125 is not sealed, and the cooling operation and the disinfection and drying operation cannot be performed efficiently.

[0084] Therefore, in the ninth embodiment, as shown in FIG. 19(b), a strip-shaped seal material is disposed between the back surfaces of the two disinfection storage cabinets 10 so as to go around the outer periphery of the communication opening 125a. Specifically, a fluororesin seal 126 containing polytetrafluoroethylene (PTFE), a type of fluororesin, and having excellent heat resistance is used as the strip-shaped seal material. That is, the fluororesin seal 126 is attached to the back surface (the outer periphery of the communication opening 125a) of one of the disinfection storage cabinets 10, and the back surfaces of both disinfection storage cabinets 10 are pulled together and fixed to each other using bolts and nuts to the extent that the fluororesin seal 126 is crushed, thereby forming the connecting machine 125. By disposing the fluororesin seal 126 between the two disinfection storage cabinets 10 in this way to close the gap, the storage space 125b can be sealed, and the efficiency of the cooling operation and the disinfection and drying operation can be improved to suppress energy consumption. In addition, the occurrence of condensation on the outer surface of the connecting machine 125 due to the leakage of cold air during the cooling operation can be prevented.

[0085] [Example of change] The present application is not limited to the configurations of the above-described embodiments, and for example, the following configurations can be appropriately adopted. (1) In Examples 1 to 9, a cart-in type disinfection storage cabinet has been described. However, the configuration of the examples can also be applied to a disinfection storage cabinet in which shelves for placing items (goods) such as tableware are provided inside the storage chamber and a tableware cart cannot be brought in. (2) In Examples 1 to 9, the openings at the front end (opening) of the housing are used as the inlet and outlet of the tableware cart, but the inlet (opening) of the tableware cart may be provided at the front end (opening) of the housing and the outlet (opening) of the tableware cart may be provided at the rear end (opening) of the housing, and each opening may be opened and closed by a separate door. In this case, the configuration of the example may be applied to either one of the openings or the door, or the configuration of the example may be applied to both of the openings or the doors. (3) In Examples 1 to 9, a bendable linear electric heater (cord heater) was provided in the passage hole formation portion as a condensation prevention heater, but a bendable band-shaped electric heater or other electric heater that cannot be bent may also be provided in the passage hole formation portion as a condensation prevention heater. (4) In Examples 1 to 9, the heat values ​​of the multiple anti-condensation heaters (top heater, side heater, and bottom heater) provided in the passage formation portion were made different from each other, but the heat values ​​of any two or all three of the anti-condensation heaters may be the same. (5) In Examples 1 to 9, the overall lengths of the multiple anti-condensation heaters (top heater, side heater, and bottom heater) provided in the passage formation portion are made different from one another, but the overall lengths of any two or all three of the anti-condensation heaters may be the same. (6) In the first to ninth embodiments, all of the condensation prevention heaters (top heater, side heater, and bottom heater) are operated when the inside temperature during the cooling operation drops to a specific temperature higher than the temperature that lowers the surface temperature of the top partition to the dew point temperature, but any of the condensation prevention heaters other than the top heater may be operated before the inside temperature reaches the specific temperature (for example, from the start of the cooling operation). Also, the specific temperature may be set to a temperature higher than the temperature that lowers the surface temperature of the front of the side partition or bottom plate to the dew point temperature. (7) In Examples 1 to 9, when the right door is closed with the left door closed, the gasket of the right door comes into contact with the partition piece of the left door. However, the gasket of the right door may be configured to come into contact with the covering plate portion of the third insulator (insulator) that covers the partition piece. (8) In the first, second, and fourth to ninth embodiments, the fitting hole of the first insulator made of synthetic resin is elongated, while the fitting hole of the third insulator is circular. However, the fitting hole of the third insulator may be elongated. Also, the fitting hole of the first insulator may be circular, and the fitting hole of the second insulator made of silicon may be elongated. (9) In Examples 1 to 9, the first and third insulators (insulators) are formed from a synthetic resin material, and the second insulator (insulator) is formed from a silicone material. However, the first insulator or the third insulator may be formed from a silicone material, and the second insulator may be formed from a synthetic resin material. (10) In the fourth to sixth embodiments, an inclined portion is provided on the partition piece of the left door, and the seal member is disposed along the inclined portion, so that the seal member extends obliquely to the front side and elastically contacts the rear surface of the right door. In contrast, the seal member may be configured with a mounting base that is attached along the partition piece (extending base portion) and a flexible plate portion that is bent relative to the mounting base so that the surfaces form an obtuse angle, so that the flexible plate portion extends obliquely to the front side relative to the mounting base and elastically contacts the rear surface of the right door. (11) In the sixth embodiment, two flexible plates are provided in the seal member disposed on the partition piece (inclined portion) of the left door, but the number of flexible plates may be three or more. Also, in the sixth embodiment, one of the two flexible plates (the second flexible plate) is provided as a part of the cover portion that covers the head of the screw member, but this cover portion may not include a flexible plate (the second flexible plate), and only one flexible plate (the first flexible plate) may be configured to elastically contact the rear surface of the right door.
