Description

Refrigerator with a door

Divisional patent application

The application is a divisional application of an invention patent application with the invention name of 'refrigerator' and the application number of 201380044443.4, and the application date of the original application is 2013, 08 and 15 days.

Technical Field

The present invention relates to a refrigerator.

Background

A conventional refrigerator has a glass plate disposed on a front surface of a door, and an operating portion provided on a rear surface of the glass plate. The operation unit is provided at a position corresponding to a detection unit of a capacitive touch switch (touch switch), for example. When the user operates the operation unit from the glass plate, the detection unit detects the operation of the operation unit, and functions such as quick freezing, quick refrigerating, and an automatic ice making device can be operated.

A box cover (box cover) is disposed at the inner side of the glass plate, and a guide groove (guide slot) is formed at the box cover. The guide groove has the following functions: the base member inserted into the insertion portion of the door is slid into the box cover to be guided. That is, the slider of the substrate case provided in the substrate member slides the guide groove, thereby placing the substrate member in the case cover. Thereby, the detection portion of the operation portion positioned on the substrate of the substrate member can be brought into close contact with or close to the glass plate (see patent document 1).

Disclosure of Invention

The technique disclosed in patent document 1 is a structure in which a base member is housed in a box cover by sliding the base member using a guide groove. Therefore, depending on the accuracy of the guide groove (the forming accuracy of each unit, the change over time, and the mounting accuracy), the substrate member may be displaced in the lid due to vibration or the like during the operation of the refrigerator. This may change the degree of adhesion of the substrate member to the glass plate, and may cause a change in the visibility of the display.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a refrigerator in which an operation portion is prevented from being displaced due to vibration or the like during operation of the refrigerator, a glass plate can be reliably brought into contact with the operation portion, and the operation portion can be easily operated from the glass plate.

The refrigerator of the present embodiment includes: a glass plate disposed in front of the door; an operation part for setting operation of each function of the refrigerator; a storage section provided behind the glass plate and storing the operation section; and a moving member for moving the operation portion forward in the housing portion and bringing the operation portion into contact with the rear surface of the glass plate.

The ice making chamber 8 is opened and closed by a sliding door 8 a. The upper freezing chamber 9 is opened and closed by sliding a door 9 a. At the lowermost portion of the body 2, i.e., the lower sides of the ice making chamber 8 and the upper freezing chamber 9, there is provided a freezing chamber 10.

The freezing chamber 10 is opened and closed by sliding the door 10 a. Recessed handles 3b and 4b for placing fingers are provided at the lower portions of the first and second refrigerating compartment doors 3 and 4, respectively. Recessed handles 7b, 8b, 9b, and 10b for placing fingers are provided at the inner portions of the sliding doors 7a, 8a, 9a, and 10 a.

Glass plates 13 and 14 are provided on outer surfaces of the refrigerating compartment first door 3 and the refrigerating compartment second door 4, respectively. A glass plate 17 is provided on the outer surface of the sliding door 7 a. Glass plates 18, 19, 20 are provided on outer surfaces of the ice making compartment 8, the upper freezing compartment 9 and the freezing compartment 10, respectively. The glass plates 13, 14, 17, 18, 19, 20 are transparent or translucent.

The first door 3 of the refrigerating compartment shown in fig. 2 is a left side door toward the refrigerating compartment 5 in fig. 1. The first refrigerating compartment door 3 includes an upper door cover (cap)21, an outer door cover 22, a lower door cover 23, an inner door cover 24, a door inner member 25, a frame-like back member 26, a storage case (box)30 as a storage portion, an operation portion 31 stored in the storage case 30, and a press-fitting member 32. The glass plate 13 is a rectangular member that is long in the longitudinal direction.

The upper door 21, the outer door 22, the lower door 23, and the inner door 24 are attached to the peripheral edge portions of the glass plate 13, respectively, thereby constituting a frame for supporting and fixing the glass plate 13. Specifically, an upper door 21 is attached to the upper side of the glass plate 13, an outer door 22 is attached to the outer side of the glass plate 13, a lower door 23 is attached to the lower side of the glass plate 13, and an inner door 24 is attached to the inner side of the glass plate 13. The inner door 24 has an opening 24R formed at a central position in the longitudinal direction Z, and the opening R is elongated in the longitudinal direction Z.

The door inner 25 is a rectangular member fixed to the rear surface 13N of the glass plate 13. The rear surface 13N of the glass plate 13 is the inner surface of the glass plate 13. The back member 26 is fixed to the rear surface 13N side of the glass plate 13 in a state of sandwiching the door inner member 25. The storage case 30 is provided on the rear surface 13N of the glass plate 13, i.e., behind the glass plate 13. Storage cassette 30 detachably stores operation unit 31.

As shown in fig. 3, storage case 30 includes 4-sided edge portion 30P for attachment and back surface portion 100. When the storage case 30 is attached to the rear surface 13N side of the glass plate 13, the edge portion 30P is temporarily fixed to the rear surface 13N of the glass plate 13 with the double-sided tape 30S. Thereafter, polyurethane foam (polyurethane) is injected into the space between the glass plate 13 and the door inner 25. The storage case 30 is fixed (pressed) to the rear surface 13N of the glass plate 13 by the adhesive force and the pressing force of the foamed urethane. In the storage cassette 30, an operation portion 31 is detachably inserted along an insertion direction T (a direction downward in the vertical drawing in fig. 3). The operation unit 31 is pressed into the rear surface 13N side of the glass plate 13. That is, the operation portion 31 is abutted so as to be in close contact with the rear surface of the first refrigerator compartment door 3.

As shown in fig. 4, the operation unit 31 includes a plastic shield plate 40, a rectangular operation substrate 41, a reflection plate 42, a transparent electrode 43 as a detection unit, and an operation indicator plate (name plate) 44. The operation portion 31 is a rectangular plate-like member elongated in the longitudinal direction Z. An LED (diode) 41A, which is an example of an illumination device, having a plurality of light emitting elements is mounted on the operation substrate 41 in a predetermined pattern (pattern).

A driving unit for driving each LED 41A and a determination circuit (not shown) for determining whether or not a user touches the touch panel based on a change in capacitance of the transparent electrode 43 are mounted on the operation substrate 41. The shielding plate 40 is a rectangular member elongated in the insertion direction T, and the shielding plate 40 is disposed to overlap the surface of the operation substrate 41. The shield plate 40 includes a plurality of

circular recesses

40A, 40B. The

recesses

40A and 40B are arranged along the longitudinal direction Z.

The reflector 42 includes a plurality of

circular portions

42A and 42B along the longitudinal direction Z. The

circular portions

42A, 42B are disposed corresponding to the

concave portions

40A, 40B. The

circular portions

42A and 42B are elastically deformable in the K direction, and can closely adhere to each other in accordance with the expansion of the glass plate 13.

The transparent electrode 43 is disposed on the surface of the shielding plate 40 so as to cover the reflection plate 42. The operation indicator plate 44 is a rectangular plate-like member elongated in the longitudinal direction Z, and is disposed on the surface of the shielding plate 40 so as to cover the transparent electrode 43. The operation indication plate 44 is closely attached to the rear surface 13N of the glass plate 13. The operation display panel 44 is provided with an operation display unit 99 such as a plurality of operation function display buttons (buttons) formed by printing, for example. The operation display portion 99 is clearly displayed to the user through the glass plate 13. Thereby, the user can perform an operation while checking the operation display portion 99 through the glass plate 13.

The user can perform setting operations of each function of the refrigerator 1 by touching the outer surface 13M of the glass plate 13 with a finger while looking at an arbitrary portion of the operation display portion 99 of the operation indication plate 44 through the glass plate 13. For example, when the user touches the outer surface 13M of the glass plate 13 with a finger, the capacitance of the transparent electrode 43 changes. A determination circuit (not shown) mounted on the operation substrate 41 determines the change in capacitance. Thereby, the determination circuit notifies the control unit of the operation substrate 41 which function is instructed by the user. The control portion of the operation substrate 41 instructs the main body side control portion on the refrigerator 1 side of the function to be operated. Thus, the user can perform rapid cooling operation by setting the indoor temperatures of the refrigerating compartment 5, the vegetable compartment 7, the ice making compartment 8, the upper freezing compartment 9, and the freezing compartment 10, for example.

As shown in fig. 5 and 6, operation portion 31 is inserted into case 30 along insertion direction T, and push-in member 32 is inserted into case 30 along insertion direction T. Thus, the operation portion 31 abuts against the rear surface 13N of the glass plate 13 in a pressed state, and the abutting state of the operation portion 31 can be maintained. Storage case 30 includes edge portion 30P, side surface portion 70 formed to extend in longitudinal direction Z, and back surface portion 100. The side surface portion 70 includes an opening 50 formed to extend in the longitudinal direction Z. The edge portion 30P is provided with a double-sided tape 30S. Thereby, the edge portion 30P is closely adhered and fixed to the rear surface 13N of the glass plate 13. Back surface portion 100 is disposed on the back surface side of storage case 30 so as to face inserted operation portion 13.

The side surface portion 70 of the storage case 30 is fitted into the opening 24R of the inner door 24. The position of the opening 50 of the side surface portion 70 coincides with the position of the opening 24R of the inner door 24, and the opening 50 of the side surface portion 70 is located within the range of the opening 24R of the inner door 24. Thus, the operation portion 31 can be inserted into and accommodated in the accommodation case 30 through the opening 24R of the inner door cover 24 on the rear surface 13N of the glass plate 13 of the first door 3 of the refrigerating chamber, and the press-fitting member 32 can be inserted into the opening 50 of the accommodation case 30.

Next, referring to fig. 4, the shield plate 40 of the operation unit 31 will be described in more detail.

The shield plate 40 includes a front end portion 51 inserted to the front end side in the longitudinal direction Z, a rear end portion 52 on the opposite side, an upper end portion 53, and a lower end portion 54. For example, 3

insertion portions

55, 56, and 57 are provided at intervals on the front end side 51 of the shield plate 40.

Insertion portions

55, 56, and 57 protrude in the insertion direction T of insertion housing case 30. The uppermost insertion portion 55 is provided above the distal end side portion 51. The intermediate insertion portion 56 is provided at an intermediate position of the distal end side portion 51. The lowermost insertion portion 57 is provided at a lower portion of the distal end side portion 51. The 1 st elastically deforming part 61 is provided at the upper end 53 of the shielding plate 40. The 2 nd elastically deforming part 62 is provided at the lower end 54 of the shielding plate 40.

The

insertion portions

55, 56, and 57 have a function of inserting only the operation portion 31 into the housing case 30 along the insertion direction T, and moving the operation portion 31 to the rear surface 13N side of the glass plate 13 by a cooperative operation of a moving member (described later) to press the glass plate to be in close contact with the rear surface 13N.

The 1 st elastic deformation portion 61 and the 2 nd elastic deformation portion 62 are formed in an up-down symmetrical shape and have substantially the same configuration. The lower side of fig. 4 represents the enlarged view of the 2 nd elastically deforming part 62. The 1 st elastically deforming part 61 includes a base end portion 63 fixed to the upper end portion 53, and a free end portion 64 bent and extended from the base end portion 63. Similarly, the 2 nd elastically deforming part 62 includes a base end portion 63 fixed to the lower end portion 54, and a free end portion 64 bent and extended from the base end portion 63. The 1 st elastic deformation portion 61 and the 2 nd elastic deformation portion 62 have a function of pressing the operation portion 31 toward the rear face 13N side of the glass plate 13, i.e., along the front direction P (pressing direction).

The front P is perpendicular to the longitudinal direction Z and the insertion direction T.

Next, the structure of the housing chamber 30 will be described in more detail with reference to fig. 5 and 6.

Storage box 30 is disposed on rear surface 13N side of glass plate 13 of first door 3 of the refrigerating compartment, and accommodates operation portion 31. Storage case 30 includes side surface portion 70, receiving portion 71 for positioning, edge portion 30P, storage space 72 for storing operation portion 31, and back surface portion 100. The side surface portion 70 of the storage case 30 engages with the opening 24R of the inner door 24.

The receiving portion 71 is provided inside the edge portion 30P so as to project toward the opening 50 along a direction T1 opposite to the insertion direction T into the housing space 72. The receiving portion 71 receives and fixes the insertion portion 56 at an intermediate position of the rim portion 30P in the longitudinal direction Z. The receiving portions 71 are provided at positions facing each other in the housing chamber 30 so as to receive and fix the insertion portion 56 entering along the insertion direction T when the operation portion 31 is inserted in the insertion direction T.

Accordingly, in the housing space 72 of the housing case 30, the insertion portion 56 automatically catches the receiving portion 71 by merely inserting the operation portion 31 in the insertion direction T. That is, the receiving portion 71 and the insertion portion 56 have a function as a positioning member for positioning so that the operation portion 31 does not move in the vertical direction Z (vertical direction) in the storage space 72 of the storage case 30. Although the operation portion 31 has a shape elongated in the longitudinal direction Z, by providing the receiving portion 71 in the storage case 30, even if the refrigerator 1 vibrates due to operation, the operation portion of the outer surface 13M of the glass plate 13 and the operation display portion 99 of the operation indicator plate 44 of the operation portion 31 do not shift relative to the longitudinal direction Z.

Next, a structure of the press-fitting member 32 will be described with reference to fig. 5.

The press-fitting member 32 includes a cover 80, 2 moving

members

81 and 82, 2 cap

removal prevention members

91 and 92, and a protrusion 93. The lid 80 is a rectangular member formed to extend in the longitudinal direction Z so as to detachably close the opening 50 of the storage case 30. The moving

members

81 and 82, the cap

removal prevention members

91 and 92, and the protruding portion 93 are provided to protrude at intervals in parallel along the insertion direction T from the inner surface side.

The moving

members

81 and 82 are long-arm members and are provided at the upper end and the lower end of the cover 80, respectively. The cap

removal prevention members

91 and 92 and the protruding portion 93 are provided at intervals between the moving

members

81 and 82 so as to be symmetrical in the longitudinal direction perpendicular to the insertion direction. The moving

members

81 and 82 protrude in the insertion direction T to the side of the insertion tip of the operation portion 31 (shielding plate 40). On the back side of the moving

members

81 and 82, a reinforcing rib (rib) for preventing deflection is formed. The cap

removal prevention members

91, 92 and the moving

members

81, 82 are relatively short in length in the insertion direction T. The protruding portion 93 is shorter and wider than the cap

removal prevention members

91, 92.

The protruding portion 93 formed to protrude from the cover 80 is a U-shaped cut-out portion 93a rising in an arcuate shape toward the front side. The protruding piece 93b surrounded by the cutout 93a has elasticity to strongly press the peripheral portion of the operation portion 31, that is, the rear end side portion 52 of the shielding plate 40 forward, by the cutout 93a, so that the protruding piece 93b passes through the cutout 93 a.

The moving

members

81 and 82, the lid

release preventing members

91 and 92, and the protruding portion 93 function to strongly press the operation portion 31 along the front direction P on the rear surface 13N side of the glass plate 13.

The moving

members

81, 82 preferably include elastically deforming

portions

81A, 82A, respectively, the elastically deforming

portions

81A, 82A being inclined to the insertion direction T toward the insertion direction T. When the elastically

deformable portions

81A and 82A of the moving

members

81 and 82 are inserted into the storage space 72 of the storage case 30 along the insertion direction T, they are elastically deformed in the SR direction as shown in fig. 5, and thereby have a function of pressing the operation portion 31 along the front P on the rear surface 13N side of the glass plate 13.

When the lid

removal prevention members

91 and 92 are inserted into the storage space 72 of the storage box 30 along the insertion direction T, the lid 80 does not slip out from the opening 50 in the direction of T1, and has a function of pressing the operation portion 31 along the front direction P on the rear surface 13N side of the glass plate 13.

Next, referring to fig. 7(a) to 7(B) to 9(a) to 9(C), a structural example of the moving

members

81 and 82 for pressing the rear surface 13N side of the glass plate 13 in the storage space 72 of the storage case 30 will be described.

Back surface portion 100 of case 30 is formed from side surface portion 70 of case 30 to edge portion 30P on the back side, and back surface portion 100 of case 30 is inclined in a slightly tapered manner along insertion direction T. That is, rear portion 100 is inclined from opening 50 of storage case 30 to edge 30P on the insertion distal end side.

Rear surface portion 100 further has step portion 101 at edge portion 30P on the insertion tip side. The stepped portion 101 is formed to be narrower from the back surface portion 100, and is inclined further along the insertion direction T. The

insertion portions

55, 56, 57 are caught in the insertion direction T in the stepped portion 101. As described above, the inclined portions 102 of the

insertion portions

55, 56, 57 are caught in the stepped portion 101, and the stepped portion 101 causes the operation portion 31 to press and adhere to the rear surface 13N of the glass plate 13 by moving forward P. That is, the stepped portion 101 and the

insertion portions

55, 56, and 57 constitute a moving member 200 that presses the operating portion 31 against the rear surface 13N of the glass plate 13 by moving forward P.

The tip of the moving member 81 on the upper side of the press-fitting member 32 is an inclined portion 103 so as to be easily inserted into the housing space 72. As shown in the state of fig. 5 to the state of fig. 6, when the moving member 81 of the press-fitting member 32 is inserted into the housing case 30 along the insertion direction T, the outer portion 109 of the moving member 81 is pressed by the inclined back surface portion 100 and moves forward P. Thereby, the moving member 81 itself is elastically deformed in the SR direction, and the inner portion 104 of the moving member 81 presses the 1 st elastically-deformed portion 61 at the corresponding position along the front P. Therefore, the moving member 81 presses and adheres the operation portion 31 to the rear surface 13N of the glass plate 13 by moving forward P by the 1 st elastically deforming part 61. As described above, not only the moving member 81 but also the back surface portion 100 of the storage case 30 and the 1 st elastically deformable portion 61 of the operation portion 31 constitute the moving member 250 that is pressed and brought into close contact with the rear surface 13N of the glass plate 13 by moving the operation portion 31 forward P with respect to the rear surface 13N.

Similarly, the tip of the moving member 82 below the press-fitting member 32 is an inclined portion 103 so as to be easily inserted into the housing space 72. As shown in the state of fig. 5 to the state of fig. 6, when the moving member 82 of the press-fitting member 32 is inserted into the housing case 30 along the insertion direction T, the outer portion 109 of the moving member 82 is pressed by the inclined back surface portion 100 and moves forward P. Thereby, the moving member 82 itself is elastically deformed in the SR direction, and the inner portion 104 of the moving member 82 presses the 2 nd elastically-deformable portion 62 at the corresponding position along the front P. Therefore, the moving member 82 presses and adheres the operating portion 31 to the rear surface 13N of the glass plate 13 by moving forward P by the 2 nd elastically deforming portion 62. As described above, not only moving member 82, but also back surface portion 100 of storage case 30 and 2 nd elastically deformable portion 62 of operation portion 31 form moving member 250 that is pressed and brought into close contact with operation portion 31 by moving forward P with respect to back surface 13N of glass plate 13.

Back surface portion 100 of storage case 30 is inclined to be slightly tapered in insertion direction T. That is, the back surface portion 100 is inclined from the opening 50 for accommodating the river 30 to the edge portion 30P on the insertion tip side. Rear surface portion 100 has a stepped portion 101 on the side of edge portion 30P on the insertion tip side. The level difference portion 101 is inclined along the insertion direction T. The insertion portion 56 is caught in the insertion direction T in the stepped portion 101. At this time, since the inclined portion 102 of the insertion portion 56 is caught in the stepped portion 101, the stepped portion 101 and the insertion portion 56 press the operation portion 31 against the rear surface 13N of the glass plate 13 by moving forward P. That is, the stepped portion 101 and the insertion portion 56 constitute a moving member 200 that presses the operating portion 31 against the rear surface 13N of the glass plate 13 by moving forward P.

The outer portion 109 of the moving member 82(81) is moved forward P by the inclined back surface portion 100. Thereby, the inner portion 104 of the moving member 82(81) moves the plurality of circular recesses 40A of the shielding plate 40 forward P on the rear surface 13N side of the glass plate 13 to form the moving member 300 which is pressed and adhered.

The cap

removal prevention members

91 and 92 include a protrusion 105 for holding the distal end portion. In back surface portion 100 of storage case 30, inclined portion 106 is provided in the vicinity of opening 50 along insertion direction T. When operation unit 31 is inserted into storage case 30 along insertion direction T, lid

removal prevention members

91 and 92 are pushed down along front direction P by inclined portion 106 of back surface portion 100. Thereby, the operation portion 31 is pressed along the front direction P against the rear face 13N of the glass plate 13 via the lid

release preventing members

91, 92. Thus, the lid

release preventing members

91 and 92 and the inclined portion 106 of the storage case 30 constitute a moving member 350 that presses and adheres the operating portion 31 to the rear surface 13N of the glass plate 13 by moving forward P.

When operation unit 31 is completely accommodated in storage case 30, lid 80 closes opening 50. In this state, the protrusion 105 of the cap-

off prevention members

91 and 92 engages with the engagement protrusion 107 formed on the inclined portion 106 of the storage case 30. Accordingly, even if the refrigerator 1 vibrates due to the operation, the operation portion 31 does not slip out at T1 in the direction opposite to the insertion direction T. Thus, the operation portion 31 can constantly move forward P relative to the rear surface 13N of the glass plate 13, and maintain a press-fit state.

Next, a procedure of mounting storage case 30 in glass plate 13 of first door 3 of the refrigerator, and a storage operation of storing operation unit 31 in storage case 30 after storage case 30 is mounted and stored will be described.

A storage case 30 is fixed to the rear surface 13N side of the glass plate 13 of the first door 3 of the refrigerator. That is, the storage case 30 is provided behind the glass plate 13 on the rear surface 13N of the glass plate 13. When the storage case 30 is fixed, the 4-sided edge 30P for attachment is temporarily fixed to the rear surface 13N of the glass plate 13 with the double-sided tape 30S. Thereafter, by injecting the foamed polyurethane into the first door 3 of the refrigerator, the storage case 30 is fixed (pressed) to the rear surface 13N of the glass plate 13 by the adhesive force and the pressing force of the foamed polyurethane. In this state, the side surface portion 70 of the storage case 30 is the opening 24R of the door 24 positioned inside.

Next, operation unit 31 is inserted into storage space 72 of storage cassette 30 along insertion direction T. Thereby, the operation portion 31 is positioned on the rear surface 13N side of the glass plate 13. In this way, the operation of inserting the operation portion 31 into the storage space 72 of the storage cassette 30 is a so-called free insertion operation that does not depend on a guide groove or the like.

Then, press-fitting member 32 is inserted into storage case 30 through opening 50 of storage case 30.

As described above, by inserting operation unit 31 in insertion direction T, since receiving unit 71 receives insertion unit 56, operation unit 31 is positioned in storage space 72 of storage cassette 30 so as not to move in vertical direction Z (vertical direction). Since the receiving box 30 is provided with the receiving portion 71, even if the refrigerator 1 vibrates due to operation, the operation portion of the outer surface 13M of the glass plate 13 and the operation display portion 99 of the operation indication plate 44 of the operation portion 31 do not shift in position.

The press-fitting member 32 is inserted into the housing 30 along the insertion direction T through the opening 50, and the opening 50 is closed by the cover 80 of the press-fitting member 32. That is, when the moving

members

81 and 82 and the lid

removal preventing members

91 and 92 of the press-fitting member 32 are inserted into the housing space 72 of the housing case 30, the lid 80 closes the opening 50. This improves the appearance by closing the opening 50, and prevents dust and the like from entering the storage case 30 through the opening 50.

When the moving

members

81 and 82 and the lid

removal prevention members

91 and 92 are inserted into the storage case 30, the operation portion 31 is pressed against the rear surface 13N side of the glass plate 13, and the operation portion 31 comes into close contact with the rear surface 13N of the glass plate 13. Further, the

insertion portions

55, 56, 57 are caught in the insertion direction T inside the stepped portion 101. At this time, the inclined portions 102 of the

insertion portions

55, 56, 57 are inserted into the stepped portion 101, and the stepped portion 101 presses the operation portion 31 forward P against the rear surface 13N of the glass plate 13.

When the moving member 81 of the pushing member 32 is inserted into the storage case 30 along the insertion direction T, the inner portion 104 of the moving member 81 pushes the 1 st elastically deforming part 61 located at the corresponding position along the front direction P. Thereby, the moving member 81 presses and adheres the operation portion 31 forward P against the rear surface 13N of the glass plate 13 by the 1 st elastically deforming portion 61 by elastically deforming the 1 st elastically deforming portion 61.

Similarly, when the moving member 82 of the press-fitting member 32 is inserted into the storage case 30 along the insertion direction T, the inner portion 104 of the moving member 82 presses the 2 nd elastically deforming part 62 located at the corresponding position along the front direction P. Thereby, the moving member 82 presses the operating portion 31 forward P against the back surface 13N of the glass plate 13 by the 2 nd elastically deforming part 62 by elastically deforming the 2 nd elastically deforming part 62

By inserting the moving

members

81 and 82 and the cap

removal prevention members

91 and 92 of the press-fitting member 32 into the housing case 30, the operation portion 31 is pressed against the rear surface 13N side of the glass plate 13, and the operation portion 31 is forced to be in close contact with the rear surface 13N of the glass plate 13. That is, the insertion portion 56 is caught in the stepped portion 101 along the insertion direction T, and the inclined portion 102 of the insertion portion 56 is caught in the stepped portion 101, so that the stepped portion 101 presses and adheres the operation portion 31 forward P with respect to the rear surface 13N of the glass plate 13.

The lid

removal prevention members

91 and 92 are pressed by the inclined portion 106 and elastically deformed. Thereby, the operation portion 31 is pressed along the front direction P against the rear face 13N of the glass plate 13 via the lid

release preventing members

91, 92.

The protruding portion 93 formed protruding from the cover 80 rises in an arcuate shape on the front side, and includes a U-shaped cut-out portion 93 a. The protruding piece 93b surrounded by the cut-out portion 93a has elasticity. The projecting piece 93b can press the peripheral portion of the operation portion 31, i.e., the rear end side portion 52 of the shielding plate 40, in the front direction.

When operation unit 31 is completely accommodated in storage case 30, lid 80 closes opening 50. In this state, the protrusion 105 of the cap-off preventing

members

91 and 92 engages with the engaging protrusion 107 formed on the inclined portion 106 of the storage case 30. Accordingly, even if the refrigerator 1 vibrates due to the operation, the operation portion 31 does not slip out in the direction T1 opposite to the insertion direction T.

Since the conventional refrigerator uses the guide groove to slide the base member and store it in the lid, the base member may be displaced in the lid due to vibration or the like during operation of the refrigerator depending on the accuracy of the guide groove (the forming accuracy, the change over time, and the mounting accuracy of each unit). Further, the degree of adhesion of the substrate member to the glass plate may vary due to vibration or the like during operation of the refrigerator, and the visibility of the display may vary. That is, in the conventional technology, when the substrate member is stored in the groove or the like, the degree of adhesion of the glass plate to the display surface may vary depending on the accuracy of the groove (the forming accuracy, the change over time, and the mounting accuracy of each individual member), and the visibility of the display may vary.

In contrast, in the refrigerator 1 of the embodiment, the refrigerator 1 includes the glass plate 13 disposed in front of the first door 3 of the refrigerator and the storage case 30 provided behind the glass plate 13 and storing the operation portion 31, and the storage case 30 (storage portion) includes, as moving members, preferably, for example, moving members 81 and 82 (more specifically, moving

members

200, 250, 300, and 350) which move the operation portion 31 in the storage case 30 in the forward direction P and bring the operation portion 31 into contact with the rear surface 13N of the glass plate 13. That is, the operation unit 13 is moved forward P in the storage case 30 provided on the rear surface 13N of the glass plate 13 by the moving member and mechanically abuts against the rear surface 13N of the glass plate 13.

Thus, the operation portion 31 can be clearly displayed to the user through the glass plate 13, and the user can operate the operation portion 31 while confirming it through the glass plate 13. That is, by preventing the operating portion 31 from being displaced due to vibration or the like during operation of the refrigerator 1, the operating portion 31 can be reliably brought into contact with the glass plate 13, and the operating portion 31 can be easily operated from the glass plate 13. In the embodiment, since the pressing is performed by the elastic member (the pressing amount is, for example, a configuration of the elastic member receiving the moving

members

81 and 82, or the inclination angle of the inclined surface formed on the back surface of the moving

members

81 and 82 is adjustable according to the length), it is possible to reduce the possibility that the operating portion 31 is displaced in the storage case 30 due to vibration or the like during the operation of the refrigerator.

In the refrigerator 1 of the embodiment, the operating portion 31 can be reliably brought into contact with the glass plate 13 by preventing the operating portion 31 from being displaced in the storage case 30 due to vibration or the like during operation of the refrigerator 1. Therefore, in the refrigerator 1 of the embodiment, the degree of adhesion of the operation portion 31 to the rear surface 13N of the glass plate 13 is not changed by vibration or the like during operation of the refrigerator 1, and the visibility of the display is not changed. Therefore, the user can easily operate the operation portion 31 from the glass plate 13.

Moving

members

81 and 82 are inserted between operation unit 31 and storage case 30, whereby operation unit 31 can be moved forward P. In the conventional refrigerator, when the guide groove of the substrate member is mounted in the housing portion, there is a possibility that the guide groove may be scratched while the substrate member is repeatedly detached, but such a problem does not occur in the refrigerator 1 according to the embodiment.

Moving

members

81 and 82 and stepped portion 101 of rear surface portion 100 of storage case 30 are inclined in insertion direction T in which operation unit 31 is inserted into storage case 30. Thus, by inserting the moving

members

81 and 82 into the storage case 30, the operation portion 31 can be moved forward P with respect to the rear surface 13N of the glass plate 13 in a gentle manner.

The moving

members

81 and 82 include elastic members (

elastic deformation portions

81A and 82A) for pressing the operation portion 31 by moving it forward P. In the storage case 30, for example, the back surface portion 100 and the stepped portion 101 may be configured to have elastic members elastically deformed by inserting the moving

members

81 and 82 into the storage case 30. Thus, the moving

members

81 and 82 or the back surface portion 100 and the stepped portion 101 of the storage case 30 can press the operating portion 31 against the rear surface 13N of the glass plate 13 while maintaining the elastic force in the front direction P. Therefore, the operation portion 31 can be stably pressed against the rear surface 13N of the glass plate 13 for a long period of time.

The operation portion 31 is vertically long and has a plurality of moving

members

81 and 82 in the vertical direction. Thus, even if the operation portion 31 is elongated in the longitudinal direction Z and the glass plate 13 is warped, the operation portion 31 can be brought into contact with and closely attached to the glass plate 13.

The moving

members

81 and 82 have a function of pressing the operation portion 31 against the rear surface (back surface) 13N of the glass plate 13. That is, the operation unit 31 can be moved and pressed against the rear surface (back surface) 13N of the glass plate 13 by the elastically

deformable portions

81A and 82A of the moving

members

81 and 82 provided corresponding to the upper end and the lower end of the shielding plate 40 of the operation unit 31 during attachment.

Since the inclined surface is provided on at least one of rear surface portion 100 of storage case 30 and the rear surface of the front end of moving

member

81, 82, operation portion 31 is moved and pressed on rear surface (rear surface) 13N side of glass plate 13 by storage case 30 fixed to rear surface (rear surface) 13N of glass plate 13.

The cap

removal prevention members

91 and 92 function as moving members that move and press the operation portion 31 against the rear surface (back surface) 13N of the glass plate 13, similarly to the moving

members

81 and 82. Further, the lid

release preventing members

91 and 92 function as a method for preventing the warping of the glass plate 13 and a method for preventing the operating portion 31 from slipping out in the direction T1.

An opening 50 of the storage case 30 is formed in the press-fitting member 32 in the side direction of the door 3. The moving

members

81 and 82 of the press-fitting member 32 are provided with a cover 80 for closing the opening 50. Thus, when the moving

members

81 and 82 are inserted into the storage case 30, the lid 80 closes the opening 50. Further, by removing press-fitting member 32 from storage case 30, the fixed state of operation portion 31 in storage case 30 can be released. Therefore, this operation can be easily performed when taking out operation unit 31 from storage cassette 30 and performing maintenance (maintenance) or replacement. In addition, since the wiring (printed circuit board) of the operation substrate 41 of the operation unit 31 is only in the vicinity of the opening 50, maintenance of the operation unit 31 is easy.

The press-fitting member 32 includes cap-

removal prevention members

91 and 92 for preventing the cap 80 from being removed from the opening 50. Accordingly, the cover 80 is not detached from the opening 50 by vibration or the like during operation of the refrigerator 1.

The operation portion 31 includes an insertion portion 56 as a positioning member for positioning the storage case 30 in the longitudinal direction Z. Accordingly, although the operation portion 13 is elongated in the longitudinal direction Z, the operation portion 31 can be positioned in the vertical direction Z in the storage case 30, and therefore, the position of the operation portion 31 with respect to the glass plate 13 is not displaced. Therefore, the user can surely touch the pressing operation part for performing the function of the refrigerator, and the necessary function of the refrigerator can be performed.

Insertion portion 56 as a positioning member is inserted into receiving portion 71 located at a position facing storage case 30 in insertion direction T of operation portion 31. Accordingly, as long as the operation portion 31 is inserted into the storage case 30 along the insertion direction T, the positioning of the operation portion 31 in the longitudinal direction Z can be reliably performed.

The operation portion 31 includes a shielding plate 40 as a support portion, a transparent electrode 43 as a detection portion located in front of the shielding plate 40, and an LED 41A as an illumination device located behind the shielding plate 40. The operation portion 31 is formed of a plurality of members, but can be easily assembled.
