[0081] (Insights, etc. that form the basis of this disclosure)

[0082] When the inventor thought of the present disclosure, there was a technology for installing a temperature display device that displays the temperature on the outer shell of the storage tank body. In addition, the display surface is installed in a manner that protrudes from the outer shell to block the opening of the device housing. However, in the previous technology, the inventor discovered the following problem: when the display surface and the outer shell are configured to be roughly coplanar, there is a gap between the display surface and the outer shell, so it is possible for water on the display surface to intrude along the display surface and the device housing. In order to solve this problem, the subject of the present disclosure is formed.

[0083] Therefore, the present disclosure provides a temperature display device and a storage tank capable of suppressing the intrusion of water into the temperature display device.

[0084] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. However, sometimes more detailed descriptions than necessary will be omitted. For example, sometimes detailed descriptions of already known matters or repeated descriptions of substantially the same structures will be omitted.

[0085] In addition, the drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0086] (Implementation Method 1)

[0087] [1-1. Structure]

[0088] [1-1-1. Storage structure]

[0089] Figure 1 It is a perspective view of the storage 1. Figure 2is a plan view showing the temperature display device 30 and the outer casing 20 . Figure 3 yes Figure 2 III-III sectional view. Figure 4 is a plan view of the outer profile 20. Figure 4 , a state in which the temperature display device 30 is removed is shown. Figure 5 It is an exploded perspective view of the temperature display device 30 .

[0090] The storage cabinet 1 of the first embodiment is an open showcase with a front opening installed in a store such as a convenience store or a supermarket.

[0091] The storage 1 is composed of a main body 2 which is open at the front and covers the top, back, sides and bottom, and a display room 3. The main body 2 has a heat-insulating side wall 4 and a heat-insulating side plate 5 installed on both sides of the side wall 4. An inner panel 6 is provided inside the display room 3.

[0092] The display room 3 has a front opening 7, and a pair of brackets detachably mounted on pillars in multiple layers and a shelf 8 supported by the brackets are provided inside. The pillars are provided on the front side of the inner panel 6 located on the back side of the display room 3. Furthermore, the merchandise is displayed on the upper surface of the shelf 8. That is, the storage 1 can store articles.

[0093] A compressor, a condenser, a fan, etc. constituting a refrigeration cycle are arranged below the main body 2, and an evaporator constituting a refrigeration system is arranged inside the cold air duct located at the rear side of the inner panel 6. By driving the compressor and the fan, the cold air after heat exchange with the evaporator rises inside the cold air duct and is discharged toward the front opening 7. With the cold air discharged to the front opening 7, an air curtain generated by the cold air is formed at the front opening 7, and a part of the air curtain of the cold air circulates inside the display room 3.

[0094] like Figure 1 , Figure 2 and Figure 3 As shown, the main body 2 has an outer shell 20 and a device holding portion 23 for holding the temperature display device 30 on the outer shell 20. The outer shell 20 is, for example, a metal panel member. The outer shell 20 of the storage 1 in this embodiment functions as a cover covering the upper front portion of the storage 1. The device holding portion 23 holds the temperature display device 30 at a position where a display surface 35 described later is substantially coplanar with the outer shell 20.

[0095] Main reference Figure 2 , Figure 3 and Figure 4 , the temperature display device 30 and the outer profile 20 are described.

[0096] The device holding portion 23 includes an outer shell opening 21 provided in the outer shell 20 and into which the device housing 32 is inserted. The outer shell opening 21 is formed as a through hole in the outer shell 20. The outer shell opening 21 is formed in a substantially rectangular shape. Figure 3 and Figure 4 As shown, the outer opening 21 has two steps 25 formed by bending on the short sides, that is, the two sides opposite to each other in the long side direction. In addition, the steps 25 can also be provided on the other two sides of the outer opening 21 opposite to each other.

[0097] The step portion 25 is formed in a step shape that is cranked from the surface where the outer shell opening 21 is located toward the inside of the storage box 1. The step portion 25 is formed with an engaged portion 23A that engages with the device engaging portion 50.

[0098] The engaged portion 23A is composed of the step portion 25 and the first notch portion 27 of the step portion 25 .

[0099] The temperature display device 30 is provided on the outer shell 20 of the main body 2. In addition, the direction in which the temperature display device 30 is mounted is not particularly limited, and the temperature display device 30 can be mounted in any direction.

[0100] [1-1-2. Structure of temperature display device]

[0101] Figure 6 It is an enlarged perspective view showing one end of the device casing 32 . Figure 7 yes Figure 2 VII-VII sectional view.

[0102] like Figure 5 As shown, the temperature display device 30 includes: a device housing 32 formed in a substantially box shape; a device substrate 33 housed in a housing interior 32A of the device housing 32; and a device cover 31 that closes a housing opening 63 and a housing wall portion 39 of the device housing 32. In addition, the device housing 32 corresponds to an example of a "housing including a display surface".

[0103] The display surface 35 is provided with an operation button portion 35C, a display portion 35D, and an operating status display portion 35E. The display portion 35D of the display surface 35 can display temperature and can also display error codes. In addition, the operating status display portion 35E of the display surface 35 can display information indicating the operating status of the storage 1. Furthermore, the display surface 35 can also operate the operating status of the storage 1 through the operation button portion 35C, thereby, the temperature display device 30 can also function as a controller. In this way, the temperature display device 30 is not limited to displaying only temperature. That is, the temperature display device 30 can only display temperature, or it can have other functions as the temperature display device 30 of the present embodiment.

[0104] The device housing 32 has a display surface 35 formed in a substantially flat shape.

[0105] Reference Figure 2 When viewed from a front plane with the display surface 35 as the front, the display surface 35 is formed into a substantially rectangular shape. The device housing 32 includes a housing wall portion 39 in a substantially rectangular frame shape extending from the back surface 37 of the display surface 35 toward the rear. The housing wall portion 39 has an outer shape smaller than the outer shape of the display surface 35. The back surface 37 of the display surface 35 is a surface on the opposite side to the horizontal plane 35A of the display surface 35.

[0106] The case wall 39 is formed in a substantially rectangular shape smaller than the display surface 35 when viewed from the front plane with the display surface 35 as the front. The case wall 39 is formed so that the case wall 39 is accommodated in the display surface 35 when viewed from the front plane.

[0107] The display surface 35 has a flange portion 41 extending from the display surface 35 . A flange back surface portion 41A of the flange portion 41 , which constitutes a surface opposite to the display surface 35 , is formed to extend from the periphery of the case wall portion 39 to the periphery of the display surface 35 .

[0108] like Figure 3 , Figure 5 and Figure 6 As shown in FIG. 1 , the outer peripheral surface 39A of the case wall portion 39 is formed watertight without a through hole. The device engaging portions 50 are provided on two surfaces in the short-side direction of the outer peripheral surface 39A of the case wall portion 39 .

[0109] When the temperature display device 30 is viewed from the surface opposite to the display surface 35, the device engagement portion 50 is formed in a substantially U-shape. Figure 7 The device engaging portion 50 forms a gap between the inner surface 50A of the device engaging portion 50 and the outer peripheral surface 39A of the housing wall portion 39. As described later, a communication port 61 is formed inside the device engaging portion 50.

[0110] like Figure 6 As shown, a side portion 51 formed substantially parallel to the housing wall portion 39 in the device engaging portion 50 is provided with a second notch portion 53 in a direction substantially perpendicular to the horizontal plane 35A where the display surface 35 is located. The device engaging portion 50 includes a movable portion 55, which is formed to be able to swing in a direction close to the outer peripheral surface 39A of the housing wall portion 39 by means of the second notch portion 53.

[0111] The movable portion 55 constitutes a part of the side portion 51. The movable portion 55 includes a claw portion 57 formed to protrude in a direction away from the display surface 35, and a movable wall portion 59 provided at a position closer to the display surface 35 than the claw portion 57. That is, the device engaging portion 50 includes the claw portion 57 engaged with the device holding portion 23, and the claw portion 57 and the movable wall portion 59 are integrally formed in a movable manner.

[0112] like Figure 6 and Figure 7 As shown, the claw portion 57 has: a snap-fit ​​portion 57A formed in the short side direction of the temperature display device 30; and an inclined portion 57B formed to be inclined toward the center side of the display surface 35 as it moves away from the horizontal plane 35A where the display surface 35 is located in the vertical direction. The inclined portion 57B is formed to be inclined from the snap-fit ​​portion 57A toward the device cover 31.

[0113] The claw portion 57 is formed to be attachable and detachable relative to the engaged portion 23A of the device holding portion 23. In addition, the claw portion 57 is formed with a communication port 61 that communicates in a direction perpendicularly intersecting the horizontal plane 35A of the display surface 35. That is, the interior of the device engaging portion 50 is connected from the movable wall portion 59 side to the end of the movable portion 55 on the side farther from the display surface 35, forming a space S. And the space S communicates with the third notch portion 70 described later.

[0114] like Figure 6 As shown in FIG. 5 , the movable wall portion 59 is formed to extend from the end portion of the second notch portion 53 that is close to the display surface 35. In other words, Figure 7 As shown in FIG. 1 , the movable wall portion 59 is formed so as to protrude from the flange back surface portion 41A toward the display surface 35 . When the display surface 35 is regarded as the upper surface, the movable wall portion 59 is formed on the upper portion of the movable portion 55 .

[0115] like Figure 6 and Figure 7 As shown, the claw portion 57 is formed with a gap portion 65 on the side of the claw portion 57 close to the display surface 35. The first notch portion 27 of the engaged portion 23A is configured to be inserted into the gap portion 65. The gap portion 65 is formed at a position surrounded by the side of the flange portion 41 opposite to the display surface 35, the movable wall portion 59, and the engaging portion 57A of the claw portion 57 in the claw portion 57.

[0116] like Figure 2 , Figure 6 as well as Figure 7 As shown, a third notch portion 70 facing the device engaging portion 50 is formed on the display surface 35. In addition, a third notch portion 70 facing the movable wall portion 59 of the device engaging portion 50 is formed on the display surface 35.

[0117] Furthermore, if Figure 7 As shown, a third notch portion 70 is formed on the display surface 35 at a position overlapping with the device engaging portion 50 in a direction perpendicular to the horizontal plane 35A where the display surface 35 is located. In addition, the third notch portion 70 is formed to face the step portion 25 and is formed to communicate with the engaged portion 23A. Moreover, the third notch portion 70 is arranged to communicate with the communication port 61.

[0118] In addition, the third notch portion 70 only needs to be formed so that the device engaging portion 50 can be entered by a tool by inserting the tool from the outside of the outer profile 20. In addition, the third notch portion 70 facing the device engaging portion 50 also includes a structure in which the device engaging portion 50 cannot be visually confirmed from the third notch portion. The third notch portion 70 in the present embodiment is formed so that the device engaging portion 50 can be visually confirmed. However, for example, the third notch portion 70 can also be formed in a curved manner in which the device engaging portion 50 cannot be visually confirmed, and can also be formed with a width in which the device engaging portion 50 cannot be visually confirmed. In these cases, it is also possible to enter the device engaging portion 50 using, for example, a tool formed by bending at the end, or a tool having a diameter that can be inserted through the third notch portion 70.

[0119] In addition, if Figure 2 As shown, the third notch portion 70 is only provided at a position overlapping with one of the two device engaging portions 50 .

[0120] like Figure 5 , Figure 6 and Figure 7 As shown, in the display surface 35, the fourth notch 71 is formed on two sides of the outer peripheral portion 35B of the display surface 35 in the short side direction. The fourth notch 71 is not formed in the horizontal surface 35A of the display surface 35, and is configured as a substantially rectangular notch several times larger than the third notch 70.

[0121] The fourth notch 71 is formed on the surface of the flange 41 on the opposite side to the display surface 35, and the position of the flange 41 where the fourth notch 71 is formed does not abut against the outer shell 20. The fourth notch 71 is formed on the flange back surface 41A. By inserting a plate-shaped tool, for example, into the fourth notch 71, the tool can enter the device engagement portion 50.

[0122] like Figure 7 As shown, the third notch 70 has an inclined surface 70A which is inclined toward the center of the display surface 35 as it moves away from the horizontal plane 35A where the display surface 35 is located in the vertical direction. The movable wall portion 59 is arranged so that the corner portion 59A of the movable wall portion 59 which is located outside the temperature display device 30 is located inside the temperature display device 30 more than the innermost portion 70B of the third notch 70. In other words, the movable wall portion 59 is located closer to the center of the display surface 35 than the third notch 70.

[0123] [1-1-3. Structure of equipment substrate]

[0124] Figure 8 It is a plan view showing the device case 32 and the device substrate 33. Fig. 9 It is a plan view showing the device substrate 33. Fig.10 It is a perspective view showing the casing interior 32A of the device casing 32 .

[0125] like Fig. 9 As shown, the temperature display device 30 includes a device substrate 33 for controlling the display on the display surface 35 .

[0126] First, the device substrate 33 will be described. Fig. 9 As shown, the device substrate 33 is provided with a plurality of light-emitting components 81 that light up when powered. The light-emitting components 81 include a first light-emitting component 83 and a second light-emitting component 85, which are sometimes collectively referred to as the light-emitting component 81. The device substrate 33 is provided with a light-emitting component 81 other than the first light-emitting component 83, namely, the second light-emitting component 85. The first light-emitting component 83 is configured in a so-called SSD (Seven Segment Display) shape, which can display Arabic numerals, letters or symbols. The first light-emitting component 83 is composed of a total of seven light-emitting components 81.

[0127] The second light emitting component 85 is used for indicating a decimal point or indicating the operating state of the storage 1 . As the light emitting component 81 , for example, an LED (Light Emitting Diode) can be cited. In addition, a plurality of light emitting components 81 are provided on the same plane of the device substrate 33 .

[0128] like Fig.10 As shown, there are provided: a light emitting component storage portion 91 formed to protrude from the back surface 37 of the display surface 35 and to store the light emitting component 81; and a substrate insertion portion 97 formed to protrude from the back surface 37 and to be inserted into the device substrate 33 and to position the device substrate 33. The light emitting component storage portion 91 and the substrate insertion portion 97 are formed to protrude toward the device substrate 33 side.

[0129] The light emitting component storage section 91 is configured to protrude toward the device substrate 33 and cover the periphery of the light emitting component 81. The light emitting component storage section 91 includes a plurality of first storage sections 93, each of which covers a total of four first light emitting components 83.

[0130] A total of four first housing portions 93 are provided corresponding to the number of the first light emitting components 83. The number of the light emitting components 81 is one or more, and can be changed as appropriate.

[0131] Furthermore, the light-emitting component storage section 91 includes a second storage section 95 for storing the second light-emitting component 85. The second light-emitting component 85 corresponds to the light-emitting component 81 other than the first light-emitting component 83 stored in the first storage section 93. In particular, the second storage section 95 for storing the second light-emitting component 85A for indicating a decimal point, etc. is formed integrally with the first storage section 93. Four second light-emitting components 85B for indicating the operating state of the storage 1 are stored in the second storage section 95 which is not formed integrally with the first storage section 93. In addition, as long as the temperature display device 30 can display the temperature, the four second light-emitting components 85B for indicating the operating state of the storage 1 may be omitted.

[0132] The display portion 35D of the display surface 35 is constituted by the first light emitting component 83 and the second light emitting component 85A for displaying a decimal point etc. (see Figure 2 ).

[0133] The substrate insertion portion 97 is formed integrally with the light emitting component storage portion 91. In particular, the substrate insertion portion 97 is formed integrally with the first storage portion 93.

[0134] like Fig.10 As shown in FIG. 1 , the substrate insertion portion 97 is formed in a cylindrical shape and is formed to be tapered toward the distal end. Figure 8 and Fig. 9 As shown, the device substrate 33 is provided with an insertion hole 87 at a position overlapping with the substrate insertion portion 97 when the device substrate 33 is arranged on the back of the display surface 35. In addition, the substrate insertion portion 97 may be formed in a substantially cylindrical shape. The substantially cylindrical shape includes, for example, a conical shape, a cylindrical shape, and the like.

[0135] The substrate insertion portion 97 includes a first pair 97A consisting of two substrate insertion portions 97 and a second pair 97B consisting of two substrate insertion portions 97 having a different spacing from the first pair 97A. Fig.10 As shown, the substrate insertion portion 97 only needs to be arranged asymmetrically with respect to the center line LM dividing the center of the long side direction of one first storage portion 93. Alternatively, the substrate insertion portion 97 only needs to be arranged asymmetrically with respect to a dividing line that passes through the center of one substrate insertion portion 97 and the other substrate insertion portion 97 in the short side direction of the display surface 35 and extends along the long side direction of the display surface 35. In addition, in the present embodiment, the dividing line coincides with the center line LM.

[0136] In addition, the number of substrate insertion parts 97 is more than one and can be changed appropriately. For example, it can also be configured so that the first pair 97A including two substrate insertion parts 97 is constituted by one substrate insertion part 97, and together with the second pair 97B, the temperature display device 30 has a total of three substrate insertion parts 97. In addition, it can also be configured so that the first pair 97A and the second pair 97B are respectively constituted by one substrate insertion part 97, and the temperature display device 30 has a total of two substrate insertion parts 97.

[0137] The device substrate 33 has a connector 89 for electrically connecting the temperature display device 30 to the control unit 10 of the storage 1. The connector 89 is provided on the side opposite to the position of the first light emitting component 83. In addition, the connector 89 may be directly electrically connected to the driving source instead of being electrically connected to the control unit 10, and the position where the connector 89 is provided is not limited.

[0138] Next, refer to Fig.10 The device case 32 and the device substrate 33 are described. The device case 32 includes a substrate receiving portion 99 formed so as to be located around the entire circumference of the device substrate 33 when the device substrate 33 is arranged. The device case 32 supports the device substrate 33 in a state where the substrate receiving portion 99 protruding from the case wall portion 39 abuts against the device substrate 33.

[0139] The substrate receiving portion 99 is formed to protrude toward the inner side of the case wall portion 39 and bulge toward the inside of the device case 32 , and is formed in a stepped shape.

[0140] [1-1-4. Structure of the device cover]

[0141] Fig.11 This is a perspective view of the temperature display device 30 as viewed from the device cover 31 side. Fig.12 It is a three-dimensional view of the device cover 31. Fig.13 yes Fig.11 XIII-XIII sectional view.

[0142] The temperature display device 30 has a device cover 31 that closes the housing opening 63 of the device housing 32. The device cover 31 is provided opposite to the display surface 35. The display surface 35 side of the device cover 31 is an inner surface, and the opposite side of the inner surface is an outer surface.

[0143] The device cover 31 is provided with a connector opening 110 through which the connector 89 is inserted. The connector opening 110 is configured as a rectangular through hole, and is formed near one corner of the device cover 31. In addition, an adapter or wiring connected to the connector 89 can also be inserted through the connector opening 110.

[0144] A rib 111 is formed on the outer surface of the device cover 31 around the connector opening 110. The rib 111 is formed in a convex shape so as to surround the connector opening 110. The rib 111 can prevent condensation water from intruding into the connector opening 110, especially when the temperature display device 30 is not arranged vertically downward.

[0145] like Fig.12 As shown, the device cover 31 has on its inner surface: a cover wall portion 117 protruding toward the side opposite to the inner side of the device housing 32; a cover engaging portion 113 engaged with the device housing 32 when the device cover 31 blocks the housing opening 63; and a substrate pressing portion 115 protruding toward the side opposite to the inner side of the device housing 32.

[0146] The cover wall portion 117 is formed with a size smaller than the inner periphery of the cover receiving portion 101 described later of the device housing 32, and is formed substantially perpendicular to the surface of the device cover 31. The cover wall portion 117 is formed in a wall shape, and a fifth notch portion 113A is formed on both sides of the cover engaging portion 113. Each cover engaging portion 113 is formed to be able to swing. The cover wall portion 117 is fitted into the housing opening 63 of the device housing 32.

[0147] The cover engaging portion 113 is formed to be larger in height than the cover wall portion 117 and is formed to be movable. The cover engaging portion 113 is flexible. The cover engaging portion 113 has a cover claw portion 113B at the end thereof, and the cover claw portion 113B is formed to protrude toward the housing wall portion 39 when the device cover 31 is inserted into the device housing 32. Fig.13 The cover engaging portion 113 engages with a covered engaging portion 103 formed inside the housing wall portion 39 of the device housing 32. The covered engaging portion 103 is configured as a groove formed in a concave shape.

[0148] like Fig.11 As shown, the device housing 32 is provided with a guide portion 105 at the end portion on the device cover 31 side. The guide portion 105 is formed in a notch shape. The guide portion 105 is arranged at a position overlapping with the cover engaging portion 113 when the device cover 31 is arranged in the device housing 32. The guide portion 105 has a guide surface 105A inclined toward the housing interior 32A. When the device cover 31 is inserted, the cover claw portion 113B slides on the guide surface 105A, whereby the guide surface 105A guides the cover claw portion 113B to the housing interior 32A.

[0149] like Fig.12 as well as Fig.13 As shown, the substrate pressing portion 115 is formed to protrude from the end surface of the cover wall portion 117 to the side opposite to the inner side of the device housing 32. The substrate pressing portion 115 is formed in a substantially rectangular shape, and the side of the end side can abut against the device substrate 33 when the device cover 31 closes the housing opening 63.

[0150] In addition, there are six cover engaging parts 113 and six substrate pressing parts 115, respectively, but the number and position are not limited. The cover engaging part 113 can be any structure as long as it can fit the device cover 31 into the device housing 32. The substrate pressing part 115 is arranged adjacent to the cover engaging part 113 in this embodiment, but is not limited to this, and can also be arranged at any position of the cover wall part 117.

[0151] like Fig.11 As shown, the device cover 31 is formed to be smaller than the housing opening 63. Fig.10 and Fig.13 The cover receiving portion 101 is formed in the housing opening 63 of the device housing 32. The depth of the cover receiving portion 101 from the end of the housing opening 63 is formed to be substantially the same as the thickness of the device cover 31. The device cover 31 is formed to be larger than the inner periphery of the cover receiving portion 101. Fig.13 As shown, the device cover 31 is arranged such that the periphery of the device cover 31 is covered by the housing opening 63 .

[0152] In addition, the display room 3 corresponds to an example of "inside the warehouse". The first notch portion 27 corresponds to an example of "notch in the step portion".

The shell opening 63 corresponds to an example of "an opening in the device shell". The outer shell opening 21 corresponds to an example of "an opening provided in the outer shell and into which the device shell is embedded". The movable wall portion 59 corresponds to an example of a "wall portion".

[0153] [1-2. Effects, etc.]

[0154] In the present embodiment, the temperature display device 30 is configured so that the display surface 35 is roughly coplanar with the outer shell 20. In this case, water easily intrudes from the gap between the temperature display device 30 and the outer shell opening 21 of the outer shell 20. Since the device housing 32 includes the display surface 35, it is possible to suppress water from intruding from the display surface 35 side to the inside of the temperature display device 30, compared with applying a box-shaped device cover 31 to the display surface 35. Assuming that a box-shaped device cover is applied to the display surface 35, a gap is sometimes formed on the back side of the display surface 35, and the gap needs to be sealed with a resin material, but there is no such gap in the temperature display device 30 of the present embodiment, so sealing is not required. In addition, no through hole is formed in the shell wall portion 39 of the device housing 32, thereby suppressing water from intruding into the inside of the temperature display device 30.

[0155] In addition, since the ribs 111 are formed around the connector opening 110 of the device cover 31 , it is possible to suppress water flowing along the device case 32 and the device cover 31 from intruding into the interior of the temperature display device 30 .

[0156] The device cover 31 is formed smaller than the case opening 63 of the device case 32. For example, when the temperature display device 30 is arranged with the display surface 35 facing upward, the gap between the device cover 31 and the device case 32 is located below, thereby preventing water from entering.

[0157] Furthermore, regardless of the orientation of the temperature display device 30 , water that enters from the gap between the device case 32 and the device cover 31 enters through the curved cover receiving portion 101 , so that water is less likely to enter the temperature display device 30 .

[0158] Since the space S communicating from the flange 41 side to the device cover 31 side is provided inside the claw portion 57 , the water flowing in is discharged through the space S, and water is less likely to enter the temperature display device 30 .

[0159] [1-3. Effects, etc.]

[0160] As described above, the temperature display device 30 in the present embodiment is a temperature display device 30 for displaying the temperature of the display room 3, and comprises: a device housing 32 which integrally comprises a display surface 35 and a housing wall portion 39 extending in a manner to surround the display surface 35; a control substrate which controls the display of the display surface 35; and a device cover 31 which blocks a housing opening 63 (opening) formed by the housing wall portion 39.

[0161] Thus, the device case 32 includes the display surface 35. Therefore, it is possible to suppress the intrusion of water into the temperature display device 30.

[0162] Furthermore, the device may further include: a control unit 10 ; and a connector 89 that electrically connects the temperature display device 30 and the control unit 10 , wherein the connector 89 is inserted into the housing interior 32A of the temperature display device 30 from a connector opening 110 provided in the device cover 31 .

[0163] Thus, the connector opening 110 is located on the side of the device cover 31. Therefore, it is possible to suppress the intrusion of water into the temperature display device 30. In particular, this structure is suitable when the display surface 35 is arranged in a vertically upward direction.

[0164] In addition, the device cover 31 may be provided with a rib 111 surrounding the connector opening 110 .

[0165] Thus, when water adhering to the device cover 31 flows, the rib 111 can block the water. Therefore, it is possible to suppress the intrusion of water into the temperature display device 30.

[0166] In addition, the device cover 31 may be formed to have a smaller size than the case opening 63 of the device case 32 .

[0167] Thus, the device cover 31 is arranged so that the periphery of the device cover 31 is covered by the housing opening 63. Even if water flows into the gap between the housing opening 63 and the device cover 31, it is difficult to enter the temperature display device 30. Therefore, it is possible to suppress the intrusion of water into the temperature display device 30.

[0168] In addition, the device case 32 may be provided with a cover receiving portion 101 formed in a stepped shape in the case opening 63 , and the depth of the cover receiving portion 101 may be formed to be substantially the same as the thickness of the device cover 31 .

[0169] As a result, the edge of the device cover 31 and the housing wall 39 are substantially flush with each other, thereby improving the appearance.

[0170] In addition, it is also possible that the storage tank 1 has an outer shell 20 and a device retaining portion 23 that engages with the device engaging portion 50 to retain the device engaging portion 50, and the device engaging portion 50 has a claw portion 57 that is formed to be able to be loaded and unloaded relative to the device retaining portion 23, and the claw portion 57 is formed with a connecting port 61 that is connected in a direction that intersects perpendicularly with the display surface 35.

[0171] Thereby, water is less likely to accumulate in the device engagement portion 50 . Therefore, it is possible to suppress the intrusion of water into the temperature display device 30 .

[0172] Furthermore, a third notch portion 70 (notch portion) facing the device engagement portion 50 is formed on the display surface 35 , and the third notch portion 70 is provided so as to communicate with the communication port 61 .

[0173] Thus, water entering from the third notch portion 70 can pass through the communication port 61. Therefore, it is possible to suppress the intrusion of water into the temperature display device 30.

[0174] As described above, the storage 1 in the present embodiment comprises: a main body 2, which stores articles in the display room 3; and a temperature display device 30, which displays the temperature of the display room 3, the temperature display device 30 comprises: a device housing 32, which includes a display surface 35; a device cover 31, which blocks the housing opening 63 (opening) of the device housing 32; and a device snap-fitting portion 50, the main body 2 comprises an outer shell 20 and a device retaining portion 23 for retaining the temperature display device 30 on the outer shell 20, the temperature display device 30 is arranged in a manner that the display surface 35 is substantially coplanar with the outer shell 20, the device housing 32 integrally comprises a frame-shaped housing wall portion 39 extending from the display surface 35 to the inner side of the outer shell 20, and the device cover 31 closes the housing wall portion 39.

[0175] Thus, the device case 32 includes the display surface 35. Therefore, it is possible to suppress the intrusion of water into the temperature display device 30.

[0176] (Other embodiments)

[0177] As described above, the above-mentioned embodiment 1 is described as an example disclosed in this application. However, the technology in the present disclosure is not limited thereto, and can also be applied to embodiments obtained by changes, substitutions, additions, omissions, etc. In addition, each component described in the above-mentioned embodiment 1 can also be combined as a new embodiment. Therefore, other embodiments are illustrated below.

[0178] In the above-mentioned embodiment 1, a built-in display cabinet is described in which a compressor, a condenser, a fan, etc. constituting a refrigeration cycle are arranged below the main body 2. The storage cabinet disclosed in the present invention is not limited to a built-in display cabinet. The storage cabinet 1 may also be a split-type display cabinet in which a compressor, a condenser, a fan, etc. constituting a refrigeration cycle are not arranged below the main body 2, and an outdoor unit provided with a compressor, a condenser, a fan, etc. is provided independently from the main body 2.

[0179] In the above-mentioned first embodiment, the step portion 25 is described as being bent inwardly in a crank shape from the surface of the outer shell 20. The step portion 25 is not limited to a crank-shaped step shape as long as it is a surface located inwardly of the surface of the outer shell 20. The step portion 25 may be a structure that is mounted on the back of the outer shell as a separate component, or the surface of the step portion 25 mounted on the back of the outer shell 20 may be separated from the surface where the outer shell opening 21 is located.

[0180] In the above-mentioned embodiment 1, an open-type display cabinet is exemplified as the storage 1, but it is not limited to this as long as it is a storage that can be installed with the temperature display device 30. Examples of storages include display cabinets other than open-type and horizontal (flat) types, refrigerators, freezers, constant temperature devices, hot storages, and kilns. In addition, the temperature display device 30 can generally be applied to storages equipped with a temperature display device that can display temperature.

[0181] (Variation Example)

[0182] Fig.14 2 is a cross-sectional view of an outer shell 200 according to a modified example.

[0183] The outer shell opening 210 of the outer shell 200 is formed with a smaller size than the outer shell opening 21 in the first embodiment. The upper end of the device engaging portion 50 abuts against the back of the outer shell opening 210, whereby the outer shell 200 can hold the temperature display device 30. In addition, since the temperature display device 30 has the fourth notch portion 71, the temperature display device 30 can be removed from the outer shell 200. In this way, the temperature display device 30 can be arranged to be substantially coplanar with the outer shell 20, or can also be arranged to protrude relative to the outer shell 200.

[0184] Fig.151 is a perspective view of a horizontal storage 1000 showing a modified example. In such a horizontal storage 1000, the width of the outer frame 200 where the temperature display device 30 is installed is sometimes narrow, so it is sometimes difficult to apply the step portion 25 in the first embodiment to the outer frame 200. Fig.14 As shown, the temperature display device 30 may be installed so as to protrude from the outer shell 200. Thus, the temperature display device 30 can be installed regardless of the type of storage, and the versatility is improved.

[0185] In Embodiment 1 and the modified example, the outer shell openings 21 and 210 formed into a rectangle are described. The outer shell opening only needs to be able to accommodate the temperature display device. Therefore, the outer shell opening may not be a quadrilateral. In the case where the temperature display device is formed into an ellipse, the outer shell opening may also be an ellipse. In this case, the outer shell opening has a step portion on one side and a step portion on the other side relative to an arbitrary line that divides the opening into two. In addition, step portions may be provided at two opposite locations in the long side direction of the opening of the elliptical outer shell, that is, at two locations opposite to each other with the long axis as a reference.

[0186] In addition, the above-mentioned embodiments are for illustrating the technology in the present disclosure, and therefore, various changes, substitutions, additions, omissions, etc. can be made within the scope of the claims or their equivalents.
