Description

Technical Field

[0001] The invention relates to a refrigerator, and in particular to a refrigerator capable of reducing the manufacturing cost of an indoor tray rack. Background Art

[0002] Patent Document 1 (Japanese Patent Application Laid-Open No. 2022-94101) discloses a conventional refrigerator, which includes a heat-insulating box body used as a storage room, a heat-insulating door for closing a front opening of the heat-insulating box body, and shelves for dividing the interior of the storage room into small spaces.

[0003] The frame mainly includes a glass plate, a front resin member and a reinforcing member arranged at the front end of the glass plate, a rear resin member arranged at the rear end of the glass plate, and side resin members arranged at both ends of the glass plate in the transverse width direction.

[0004] Furthermore, at the end portion on the front side of the glass plate, the reinforcing member is arranged so as to cover the front resin member. The reinforcing member is made of a material harder than the front resin member, for example, a metal material such as stainless steel.

[0005] As described above, the four side ends of the glass plate are fully protected by the front resin component, the rear resin component and a pair of side resin components. Each of these components has a different shape and is resin-molded by using a mold. Therefore, each of these four resin components is resin-molded using a different mold, making it difficult to reduce the manufacturing cost. In particular, at the front end of the glass plate, in addition to the front resin component, a reinforcing component is also used, making it even more difficult to reduce the manufacturing cost.

[0006] In addition, in a storage room equipped with shelves, the temperature of the storage room changes due to the increase in storage items and the time and number of times the insulation door is opened and closed when putting and taking out storage items. Such temperature changes cause the four resin parts to repeatedly expand and contract due to heat and cold.

[0007] However, since these four resin parts are closely arranged at the four side ends of the glass plate, they restrict each other from the above-mentioned expansion and contraction, and are difficult to stretch, especially during thermal expansion. Due to the repeated concentration of stress during thermal expansion, the fragile parts of these four resin parts are prone to cracking or deformation.

[0008] For example, at the front end of the glass plate, the front resin part is not only restricted by the reinforcing member, but also sandwiched between the glass plate and the reinforcing member, which have different linear expansion coefficients. This structure makes the front resin part easy to break or deform under the action of stress concentration. Summary of the invention

[0009] Based on the technical problems raised above, an object of the present invention is to provide a refrigerator that reduces the manufacturing cost of an indoor tray rack by protecting the ends of a glass plate in the depth direction through a decorative portion processed by extrusion molding and cap portions at both ends of the decorative portion.

[0010] In a first embodiment, the refrigerator of the present invention includes: an insulating box body forming a storage chamber; an indoor tray rack arranged on the insulating box body and partitioning the storage chamber. The indoor tray rack includes: a glass plate; a decorative part formed by extrusion molding at the end of the glass plate arranged in the depth direction of the storage chamber; and a cap part fixed to both ends of the decorative part. With this structure, the decorative part can be cut according to the length of the end of the glass plate. As a result, the manufacturing cost of the decorative part itself is reduced, and the manufacturing cost of the indoor tray rack is also reduced.

[0011] In addition, in a second embodiment of the refrigerator of the present invention, the cap portion includes: an opening portion for inserting the decorative portion; a first side portion covering the lateral end of the glass plate; a second side portion covering the end in the depth direction of the glass plate and forming a locking hole in a locked state with the decorative portion; and a third side portion covering the surface of the glass plate. A first curved surface is formed at a corner between the first side portion and the second side portion, a second curved surface is formed at a corner between the first side portion and the third side portion, and a third curved surface is formed at a corner between the second side portion and the third side portion. With this structure, when a user cleans the storage room, a cloth towel or the like is not easily hung on the indoor tray rack, thereby improving convenience.

[0012] In addition, in a third embodiment of the refrigerator of the present invention, the decorative part includes: a locking protrusion inserted into the locking hole; and a locking recess inserted into the outer peripheral edge of the locking hole of the cap part. In the locked state, the locking protrusion is substantially flush with the second side surface. With this structure, when the user cleans the storage room, a cloth or the like is not easily caught on the indoor tray rack, thereby improving convenience.

[0013] In addition, in a fourth embodiment of the refrigerator of the present invention, in the extension direction of the decorative part, the width of the outer peripheral edge is narrower than the width of the locking recess. With this structure, even if the decorative part repeatedly expands and contracts due to temperature changes in the storage chamber, the expansion amount can be absorbed by the gap between the outer peripheral edge and the locking recess, thereby preventing the decorative part from being damaged.

[0014] In addition, in a fifth embodiment of the refrigerator of the present invention, the first side surface of the cap portion is located outside the lateral end of the glass plate. With this structure, the lateral end of the glass plate is protected by the cap portion fixed to both ends of the decorative portion. As a result, when the indoor tray rack is arranged in the refrigerating room, the end of the glass plate does not contact the inner container of the storage room, thereby preventing the inner container from being damaged.

[0015] Furthermore, in the locked state of the decorative portion and the cap portion, a gap is provided between the front end side of the outer peripheral edge portion of the cap portion and the locking recess of the decorative portion in the extending direction of the decorative portion.

[0016] Furthermore, the interior lateral width W1 of the locking recess is wider than the front end side width W2 of the outer peripheral edge portion of the cap portion.

[0017] Furthermore, the decorative portion has a slope from the locking protrusion to the end of the decorative portion.

[0018] In addition, the third side surface of the cap portion and the decorative portion have a height difference region, and the height difference region is an inclined surface; and the height difference region between the third side surface of the cap portion and the glass plate is also an inclined surface; or

[0019] When the decorative portion and the cap portion are locked, the front end surface of the locking protrusion is flush with the surface of the outer peripheral edge portion of the second side surface portion of the cap portion.

[0020] In addition, the refrigerator further comprises a support frame for mounting the indoor tray rack, wherein the support frame forms recesses at the middle and rear portions in the depth direction thereof, and the shape of the recesses is suitable for the cap portion to be embedded.

[0021] Compared with the prior art, the beneficial effect of the present invention is that the refrigerator of the present invention protects the ends of the glass plate in the depth direction through the decorative part processed by extrusion molding and the cap parts at both ends of the decorative part, thereby reducing the manufacturing cost of the indoor tray rack.

[0038] like Figure 1 As shown, the refrigerator 10 includes a heat-insulating box body 11 and a storage chamber formed inside the heat-insulating box body 11. The storage chamber includes a refrigerating chamber 17, a freezing chamber 18, and a vegetable chamber 19 from top to bottom. Figure 1 In the figure, for the convenience of explanation, the numbers of the storage rooms are marked.

[0039] The refrigerator compartment 17 is located above the middle of the insulated box body 11, and utilizes approximately half of the internal space of the box body. The front opening of the refrigerator compartment 17 is opened or closed by the double-opening first insulated door 12 and the second insulated door 13 of the insulated box body 11, and the first insulated door 12 and the second insulated door 13 are opened and closed from the center. The first insulated door 12 is a revolving door, and its upper and lower ends are rotatably supported on the insulated box body 11 by a hinge mechanism (not shown). Similarly, the second insulated door 13 is a revolving door, and its upper and lower ends are rotatably supported on the insulated box body 11 by a hinge mechanism (not shown).

[0040] The freezer compartment 18 is located below the middle of the heat-insulating box body 11 and is formed below the refrigerating compartment 17. The front opening of the freezer compartment 18 is freely opened and closed by the third and fourth heat-insulating doors 14 and 15. The third and fourth heat-insulating doors 14 and 15 are doors that can be pulled out in the depth direction of the room.

[0041] The vegetable compartment 19 is located below the middle of the heat-insulating box body 11 and is formed below the freezer compartment 18. The front opening of the vegetable compartment 19 is openably closed by the fifth heat-insulating door 16. The fifth heat-insulating door 16 is a door that can be pulled out in the depth direction of the room.

[0042] like Figure 2 As shown, the heat-insulating box body 11 is mainly composed of an outer box 21 made of a steel plate forming the outer shape of the refrigerator 10, an inner liner 22 formed on the inner side of the outer box 21 and made of a box-shaped synthetic resin plate, and a heat-insulating material 23 arranged between the outer box 21 and the inner liner 22. The heat-insulating material 23 is made of foamed polyurethane.

[0043] The storage compartment inside the heat-insulating box body 11 is divided into a refrigerating compartment 17, a freezing compartment 18 and a vegetable compartment 19 from top to bottom. The refrigerating compartment 17 is separated from the freezing compartment 18 by a heat-insulating layer 24, and the freezing compartment 18 is separated from the vegetable compartment 19 by a heat-insulating layer 25.

[0044] A plurality of freely removable indoor tray racks 26 are provided inside the refrigerating chamber 17. The details will be described later. For example, three layers of indoor tray racks 26 are provided above the refrigerating chamber 17. The interior of the refrigerating chamber 17 is divided into four spaces in the vertical direction. The indoor tray racks 26 are connected by a plurality of support frames 71 (see FIG. 1 ) provided inside the inner container 22 of the refrigerating chamber 17. Fig.10 ) is fixed. The user of the refrigerator 10 can freely adjust the number and size of the internal space of the refrigerating chamber 17 by selecting the support frame 71 to be used.

[0045] A cooling chamber 27 is provided at the rear of the freezer compartment 18. A cooler 28 is provided in the cooling chamber 27. In addition, a machine room 29 is provided at the rear of the bottom of the heat-insulating box body 11. The machine room 29 is provided with equipment such as a compressor 30. The cooler 28 and the compressor 30 are connected to each other through an expansion device and a condenser and a refrigerant pipe not shown, forming a vapor compression refrigeration cycle. The various components of the vapor compression refrigeration cycle are connected to each other through a refrigerant pipe not shown.

[0046] When the above-mentioned refrigeration cycle is running, the air inside the cooling chamber 27 is cooled by the cooler 28. A blower 31 is provided above the cooler 28 in the cooling chamber 27. The blower 31 is an axial flow fan or a centrifugal fan, and sends the cold air inside the cooling chamber 27 to the refrigerating chamber 17 and the freezing chamber 18. The above-mentioned cold air is sent to each storage chamber through various air ducts 32, so that the refrigerating chamber 17 reaches the refrigerating temperature range, and the freezing chamber 18 reaches the freezing temperature range. In addition, the cold air in the refrigerating chamber 17 is sent to the vegetable chamber 19 through an air duct not shown, so that the vegetable chamber 19 reaches the refrigerating temperature range.

[0047] A defrost heater 33 is provided below the cooler 28 in the cooling chamber 27. As the refrigeration cycle runs, thick frost will form on the surface of the cooler 28. At this time, the control unit (not shown) stops the compressor 30 and energizes the defrost heater 33 to perform a defrosting operation to melt and remove the frost. As the defrost heater 33, a resistance heating heater, a tubular heater, or hot gas defrosting can be used.

[0048] like Figure 3 and Figure 4 As shown, the indoor tray rack 26 mainly includes a glass plate 41, a decorative portion 42 installed at the end of the glass plate 41, and a cap portion 43 fixed to both ends of the decorative portion 42 in the extending direction. The indoor tray rack 26 is fixed to the interior of the inner container 22 of the refrigerating chamber 17 by a plurality of support frames 71 (see Fig.10 ) to divide the internal space of the refrigerating chamber 17 into a plurality of areas in the up and down directions.

[0049] The glass plate 41 is made of, for example, highly light-transmitting transparent glass to prevent blocking of light from an indoor lamp (not shown), thereby increasing the brightness inside the refrigerating chamber 17. The glass plate 41 is a substantially square plate-shaped body that can be pulled out in the depth direction of the room and fixed to the upper surface of the liner support frame 71. In addition, the glass plate 41 is used as a placement plate for placing items stored in the refrigerating chamber 17.

[0050] The decorative part 42 is installed at least at the two end parts 41A and 41B in the depth direction of the glass plate 41. The decorative part 42 is made of a light-proof resin material, formed by extrusion molding, and then cut to a desired length for use. The length of the decorative part 42 is substantially the same as the two end parts 41A and 41B of the glass plate 41, and its cross section is substantially U-shaped. The two end parts 41A and 41B of the glass plate 41 and the surrounding parts are embedded in the interior of the decorative part 42, so that the decorative part 42 is fixed to the glass plate 41.

[0051] This structure makes the decorative part 42 a protective member to prevent the refrigerator user's hand from touching the glass plate 41 and getting injured. In addition, the decorative part 42 is made of white resin and is installed at both ends 41A and 41B of the glass plate 41, thereby improving the design and cleanliness of the refrigerator 10.

[0052] As described above, the decorative part 42 is formed into a long strip by extrusion molding, and then cut to a desired length according to the position where it is installed on the glass plate 41. The indoor capacity and the size of the internal space of the refrigerator 10 are different. However, the decorative part 42 can be cut to a desired length, thereby reducing the number of molds used to mold the decorative part 42 and reducing the manufacturing cost.

[0053] The cap portion 43 is mounted on the two end portions 42A, 42B in the extending direction of the decorative portion 42 and the surrounding portions thereof, and is fixed to the decorative portion 42. The cap portion 43 covers the four corners 41C of the glass plate 41. The details will be described later, and the cross section of the cap portion 43 is also roughly U-shaped, and the decorative portion 42 is embedded in the inside of the cap portion 43. In addition, the glass plate 41 is embedded in the inside of the decorative portion 42. The cap portion 43 is the same as the decorative portion 42, for example, formed by a light-proof resin material through a mold molding process.

[0054] like Figure 5 As shown, the cap portion 43 includes an end portion 41D covering the glass plate 41 (see Figure 4 ) or end 41E (see Figure 4 ) of the first side surface portion 51, the end portion 41A of the cover glass plate 41 (see Figure 4 ) or end 41B (see Figure 4 ), a second side portion 52 covering the front surface of the glass plate 41 , a third side portion 53 covering the back surface of the glass plate 41 , and a fourth side portion 54 covering the back surface of the glass plate 41 .

[0055] A substantially L-shaped opening 55 is formed on the opposing surfaces of the first side surface 51 and the second side surface 52 of the cap portion 43. In addition, the cap portion 43 has a hollow portion 56 for sandwiching the decorative portion 42 and the glass plate 41. With this structure, the hollow portion 56 communicates with the external space through the opening 55. The corner portion 41C of the glass plate 41 and its surrounding area are inserted into the hollow portion 56 of the cap portion 43 through the opening 55.

[0056] like Figure 6 As shown, the second side surface 52 of the cap portion 43 is formed with a locking protrusion 61 for the decorative portion 42 (see Fig.13 ) is inserted into the locking hole 57. The locking hole 57 is a longitudinal opening that connects the external space with the hollow portion 56, and is formed by the outer peripheral edge portion 52A of the second side portion 52. The details will be described later. When the decorative portion 42 and the cap portion 43 are assembled on the glass plate 41, the locking protrusion 61 of the decorative portion 42 is inserted into the locking hole 57, and at the same time, the front end side of the outer peripheral edge portion 52A of the cap portion 43 is inserted into the locking recess 62 of the decorative portion 42 (see Fig.13 ), so that the decorative portion 42 and the cap portion 43 are in a locked state.

[0057] like Fig. 9 , Fig.12As shown, the cap portion 43 has an opening portion 55 and is formed into a substantially hexahedral box-shaped body. The first side portion 51 and the second side portion 52 are continuous, and a first curved surface 58 is formed at the corner between the two. The first side portion 51 and the third side portion 53 are continuous, and a second curved surface 59 is formed at the corner between the two. The second side portion 52 and the third side portion 53 are continuous, and a third curved surface 60 is formed at the corner between the two. Similarly, the corner between the first side portion 51 and the fourth side portion 54 forms a fourth curved surface 66 (see Fig.12 ), a fifth curved surface 67 is formed at the corner between the second side surface portion 52 and the fourth side surface portion 54 (see Fig.12 ).

[0058] like Fig.13 As shown, a locking structure 40 for locking with the cap portion 43 is formed around the end portion 42A of the decorative portion 42. The locking structure 40 includes a locking hole 57 (see FIG. 5 ) into which the cap portion 43 is inserted. Figure 6 ) and the outer peripheral edge portion 52A of the inserted cap portion 43 (see Figure 6 ) The locking recess 62 on the front end side.

[0059] In addition, a slope 63 is formed from the locking protrusion 61 to the end 42A of the decorative portion 42. By forming the slope 63, the decorative portion 42 can be more easily inserted into the hollow portion 56 of the cap portion 43 (see Figure 5 ), which improves the assembly workability of the installer. The locking structure 40 is also formed at the end 42B of the decorative portion 42 (see Figure 4 ), cap portions 43 are respectively installed on the two end portions 42A and 42B in the extending direction of the decorative portion 42.

[0060] like Fig. 9 As shown, in the locked state between the decorative part 42 and the cap part 43, the locking protrusion 61 of the decorative part 42 is inserted into the locking hole 57 of the cap part 43, and at the same time, the front end side of the outer peripheral edge 52A of the cap part 43 is inserted into the locking recess 62 of the decorative part 42. In this way, the decorative part 42 and the cap part 43 are in a mutually locked state, so that the cap part 43 is not easy to fall off from the decorative part 42. The cap part 43 is, for example, a small part of about 15 mm square in a top view, but it can maintain the locked state with the decorative part 42. If the cap part 43 falls off from the decorative part 42, it can prevent the cap part 43 from being mixed into the food in the refrigerator compartment 17 and being eaten by mistake.

[0061] In the refrigerator compartment 17, when the user of the refrigerator 10 puts food or other items into or takes them out of the refrigerator compartment 17, the temperature in the refrigerator compartment 17 changes due to the opening and closing time and number of times of the insulating door being opened and closed and the number of items stored in the refrigerator compartment 17. The temperature change may cause the decorative portion 42 to expand and contract with heat, causing the decorative portion 42 to repeatedly expand and contract in the extension direction thereof.

[0062] In this embodiment, when the decorative portion 42 and the cap portion 43 are locked, the front end side of the outer peripheral edge portion 52A of the cap portion 43 has a gap with respect to the locking recess 62 of the decorative portion 42 in the extending direction of the decorative portion 42. For example, the indoor lateral width W1 of the locking recess 62 (see Fig.13 ) is greater than the front end width W2 of the outer peripheral edge portion 52A of the cap portion 43 (see Figure 6 ) is about 1 mm wide.

[0063] With this structure, the telescopic movement of the decorative part 42 in the extension direction is absorbed by the above-mentioned gap. This can prevent the stress concentration caused by the telescopic movement from occurring at the vulnerable part of the decorative part 42, thereby preventing the decorative part 42 from being damaged. In addition, when the decorative part 42 performs the above-mentioned telescopic movement, on the locking hole 57 side of the cap part 43, the cap part 43 slightly slides on the inclined surface 63 of the decorative part 42 in the depth direction of the room, which can also deal with the problem caused by the above-mentioned stress concentration.

[0064] As shown in the figure, the first to third curved surfaces 58, 59, 60 of the cap portion 43 are configured on the surface side, front side and side side of the glass plate 41. This structure can prevent the user of the refrigerator 10 from getting caught on a cloth or the like when cleaning the refrigerator compartment 17 with a cloth, thereby improving the convenience of the user. In addition, the corners of the cap portion 43 are the first to third curved surfaces 58, 59, 60, which can prevent the user from coming into contact with the cap portion 43 and getting injured when putting food or other items into or taking them out of the refrigerator compartment 17. Similarly, the back side of the glass plate 41 is also configured with the fourth to fifth curved surfaces 66, 67 of the cap portion 43 (see Fig.12 ) to achieve the same effect.

[0065] In addition, since the decoration part 42 is inserted into the cap part 43, a height difference is formed between the upper surface of the decoration part 42 and the cap part 43. Therefore, the height difference area between the third side surface 53 of the cap part 43 and the decoration part 42 is an inclined surface 64, and the height difference area of ​​the glass plate 41 is also an inclined surface 65. This structure can prevent the cloth towel from being caught in the height difference area of ​​the cap part 43, thereby improving the convenience of the user.

[0066] In addition, when the decorative portion 42 and the cap portion 43 are locked, the front end surface 61A of the locking protrusion 61 is substantially flush with the surface of the outer peripheral edge portion 52A of the second side portion 52 of the cap portion 43. This structure can prevent the cloth from being caught on the height difference area of ​​the cap portion 43, thereby improving the convenience of the user.

[0067] like Fig.10 As shown, a plurality of support frames 71 for supporting the indoor tray rack 26 are formed on the inner container 22 of the refrigerating chamber 17. The support frames 71 are formed by protruding a portion of the inner container 22 toward the inner side of the room, and extend along the depth direction of the room. The support frames 71 are formed in pairs on the side surfaces of the inner container 22 at the same height position in the lateral direction of the room, and are used to place the two end portions 41D and 41E of the long side direction of the glass plate 41.

[0068] like Fig.10 As shown, the support frame 71 is also formed in multiple layers in the vertical direction of the refrigerating chamber 17. The length of the support frame 71 in the depth direction varies according to the size of the glass plate 41. Fig.13 As shown, the third support frame 71A from top to bottom of the refrigerating chamber 17 corresponds to two glass plates 41 placed side by side in the depth direction of the room. The outer glass plate 41 can also be placed on the upper surface of the inner glass plate 41. With this structure, the user of the refrigerator 10 can select the support frame 71 for placing the indoor tray rack 26, thereby freely adjusting the spatial layout in the refrigerating chamber 17.

[0069] like Fig.11 As shown, the support frame 71 has a recess 72 formed in the middle and rear portions in the depth direction thereof. The shape of the recess 72 is suitable for the cap portion 43 of the indoor tray frame 26 to be inserted. When the indoor tray frame 26 is installed in the refrigerating chamber 17, the indoor side cap portion 43 of the glass plate 41 is inserted into the recess 72, and the outer side cap portion 43 of the glass plate 41 is stuck to the outer side of the front end portion of the indoor tray frame 26. The vicinity of the two end portions 41D and 41E of the glass plate 41 is placed on the upper surface of the support frame 71.

[0070] Therefore, both ends of the glass plate 41 of the indoor tray rack 26 are supported by the support frame 71 and are used in a substantially horizontal state. When the indoor tray rack 26 is in a stable state, the articles in the refrigerating chamber 17 can be stably placed on the upper surface of the glass plate 41.

[0071] like Fig.12 As shown, the first side surface portion 51 of the cap portion 43 is located outside the end portion 41D of the glass plate 41. The four corner portions 41C of the glass plate 41 (see Figure 4) are respectively mounted on the cap parts 43. When assembling the indoor tray rack 26, the cap parts 43 are first locked at both ends of the decorative part 42, and then the glass plate 41 is inserted into the decorative part 42. As a result, the two end parts 41D and 41E of the glass plate 41 are positioned by the first side surface part 51 of the cap part 43 and do not protrude from the decorative part 42.

[0072] With this structure, when the indoor tray rack 26 is installed, the first side surface portion 51 of the cap portion 43 contacts the inner container 22 above the support frame 71, while the glass plate 41 remains in a non-contact state with the inner container 22 above the support frame 71. This prevents the inner container 22 from being scratched by the glass plate 41. In addition, the fourth side surface portion 54 of the cap portion 43 protrudes from the back of the glass plate 41. When the indoor tray rack 26 is installed, the fourth side surface portion 54 of the cap portion 43 slides on the upper surface of the support frame 71, while the glass plate 41 remains in a non-contact state with the upper surface of the support frame 71. This also prevents the support frame 71 from being scratched by the glass plate 41.

[0073] Furthermore, as described above, since the first side surface portion 51 of the cap portion 43 is located outside the two end portions 41D and 41E of the glass plate 41, it is not necessary to cover the two end portions 41D and 41E of the glass plate 41 with the decorative portion 42. As a result, the number of components of the indoor tray rack 26 is reduced, and the manufacturing cost of the refrigerator 10 is reduced.

[0074] In the present embodiment, the cap portion 43 is attached to both end portions 41A and 41B in the depth direction of the glass plate 41 of the indoor tray rack 26 (see Figure 4 For example, the decorative portion 42 may be mounted only on the outdoor end portion 41A of the glass plate 41 without the cap portion 43 being mounted.

[0075] In addition, if Fig.10 and Fig.13 As shown, the two glass plates 41 can also be installed side by side on the support frame 71A along the indoor depth direction. In this case, the two ends 41A, 41B of the two glass plates 41 (see Figure 4 ) are provided with a decorative portion 42 and a cap portion 43 respectively. The cap portion 43 mounted on the indoor glass plate 41 and the cap portion 43 mounted on the end portion 41B of the outdoor glass plate 41 are arranged in the recess 72 of the support frame 71A. The cap portion 43 may be mounted on the end portion 41A of the outdoor glass plate 41 or may not be mounted. Various modifications can be made within the scope of the gist of the present invention.
