Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiment.

(embodiment mode 1)

[1. Whole Structure of refrigerator ]

Fig. 1 is a front view of a refrigerator according to embodiment 1 of the present invention. Fig. 2 is a sectional view of the refrigerator of fig. 1 as viewed from the direction II-II.

The overall configuration of the refrigerator 100 according to the present embodiment will be described with reference to fig. 1 and 2.

The refrigerator 100 includes a main body 1 opened in the front. As shown in fig. 2, the main body 1 includes a metal outer case 2 and a hard resin inner case 3. The main body 1 further includes a foamed heat insulating material 4 foamed and filled between the outer casing 2 and the inner casing 3. The inside of the main body 1 is partitioned by

partitions

5, 6 and the like, thereby forming a plurality of storage chambers.

As described above, the foamed heat insulating material 4 is filled between the outer casing 2 and the inner casing 3. The doors of the storage compartments of the main body 1 have the same heat insulating structure as the main body 1. The rotary refrigerating chamber door 7 is a two-piece opening/closing door. The refrigerating room left door 7a is rotatably supported by a left hinge 21, and the refrigerating room right door 7b is rotatably supported by a right hinge 22 (see fig. 3). The storage compartment is opened and closed by moving a pull-out upper freezing compartment door 8 and an ice-making compartment door 9, a pull-out lower freezing compartment door 10, and a pull-out vegetable compartment door 11 in the front-rear direction.

The storage compartment formed in the main body 1 includes an uppermost refrigerating compartment 14, an upper freezing compartment 15 disposed below the refrigerating compartment 14, an ice making compartment 16 disposed beside the upper freezing compartment 15, a lower freezing compartment 17 disposed below the upper freezing compartment 15 and the ice making compartment 16, and a vegetable compartment 18 disposed at the lowermost portion. As shown in fig. 2, a plurality of shelves 19 are provided in refrigerating room 14, and a freezer room 20 having a cooling temperature range different from that of refrigerating room 14 is provided in a lower portion of refrigerating room 14.

The refrigerating chamber 14 is a storage chamber for performing refrigerating preservation. Specifically, the temperature is usually set to 2 to 5 ℃ and the inside of the storage chamber is cooled. The freezing chamber 20 provided in the refrigerating chamber is set to-1 to-4 ℃ suitable for freezing preservation, but may be set to 0 to 2 ℃ as a fresh-keeping chamber with ice temperature by controlling the air volume.

The vegetable compartment 18 is a storage compartment that is the same as or set to a slightly higher temperature than the refrigerating compartment 14. Specifically, the temperature can be set to 3 to 7 ℃, and the inside of the storage chamber is cooled to the temperature. Since the vegetable room 18 has a high humidity due to moisture generated from food such as vegetables, dew condensation may occur during partial supercooling. Therefore, by setting the temperature to a relatively high temperature, the amount of cooling is reduced, and the occurrence of condensation due to local supercooling is suppressed.

Ice making chamber 16, upper freezer compartment 15, and lower freezer compartment 17 are storage chambers set to freezing temperature ranges, and are set to about-18 ℃.

As shown in fig. 2, a cooling chamber 23 is provided on the rear surface of lower freezing chamber 17. The cooling compartment 23 is provided with a cooler 24 constituting a refrigeration cycle and a cooling fan 25 disposed above the cooler 24 to supply cold air to each compartment. A defrosting mechanism 26, which is a glass tube heater or the like, is provided below the cooler 24.

The cooler 24 includes a refrigeration cycle in which a compressor 27, a condenser (not shown), a heat radiation pipe (not shown) for radiating heat, and a capillary tube (not shown) are annularly connected, which are disposed in a machine chamber 31 formed in an upper portion of the body 1. The cooler 24 is cooled by circulation of a refrigerant compressed by the compressor 27.

The cooling fan 25 is disposed above the cooler 24 as described above. Cooling fan 25 is configured to cool these storage compartments by supplying cold air to refrigerating compartment 14, upper freezing compartment 15, lower freezing compartment 17, ice-making compartment 16, and vegetable compartment 18 via refrigerating compartment duct 28, freezing compartment duct 29, and ice-making compartment duct and vegetable compartment duct, not shown, which are connected to the downstream side thereof.

As shown in fig. 2, a control board 30 for controlling the entire refrigerator 100 is disposed on the top surface portion 2a of the outer box 2 of the main body 1. The control board 30 controls, for example, the operation of the compressor 27, the cooling fan 25, and the like, the energization of the defrosting mechanism 26, and the temperature sensors (not shown) for controlling the storage chambers to set temperatures.

Fig. 3 is a partial perspective view of the refrigerator of fig. 1 as viewed from obliquely right above. As shown in fig. 3, refrigerator 100 includes left hinge 21 covered with left hinge cover 21a and right hinge 22 covered with right hinge cover 22a on top surface 2a of main body 1. The left hinge 21 rotatably supports the refrigerating compartment left door 7 a. Further, the right hinge 22 rotatably supports the refrigerating chamber right door 7 b.

The transverse width dimension of refrigerating room left door 7a and the transverse width dimension of refrigerating room right door 7b are different from each other, and as shown in fig. 3, refrigerating room right door 7b is formed larger than refrigerating room left door 7a in transverse width dimension. This is because the split refrigerating compartment door 7 is divided into left and right doors according to the lateral width of the ice making compartment 16 and the upper freezing compartment 15 below.

Further, the control board 30 covered with the control board cover 30a is disposed behind the left hinge cover 21a and the right hinge cover 22a on the top surface portion 2 a. Further, a machine chamber 31 is formed in the top surface portion 2a at the rear of the control board 30 by a notch portion from the top surface portion 2a to the rear surface portion 2b of the main body 1. Further, a machine chamber cover 31a that covers the compressor 27 (see fig. 2) in the machine chamber 31 is disposed behind the control board 30 of the top surface portion 2 a.

[2. Structure of hinge periphery ]

Next, the peripheral structure of the right hinge 22 covered with the right hinge cover 22a will be described.

Fig. 4 is an exploded perspective view of a main part of the periphery of the right hinge 22 of fig. 3. As shown in fig. 4, a right hinge 22 is fixed to the top surface portion 2a of the outer box 2 with screws or the like. An opening 2c is disposed in the top surface portion 2a near the right hinge 22. A substrate storage section (storage member) 36 is disposed so as to close the opening 2c from above. The board housing 36 houses the wireless communication board 34. The right hinge cover 22a is disposed to cover the right hinge 22 and the substrate accommodating portion 36. The substrate accommodating portion 36 is made of resin.

Fig. 5 is a plan view of a main part of the periphery of the right hinge, showing a state where the right hinge cover 22a is removed. As shown in fig. 5, a humidity sensor board 33 on which a humidity sensor 32 for detecting humidity is mounted is disposed in the vicinity of the right hinge 22. In addition, a wireless communication board 34 formed of a board independent from the humidity sensor board 33 is disposed in the board housing portion 36. At least an antenna unit 35 serving as a wireless communication unit is provided on the wireless communication board 34.

Since wireless communication with refrigerator 100 is set, the user performs initial setting using the mobile terminal. The initial setting is performed by direct communication with the mobile terminal and the wireless communication board 34.

If the initial setting is completed, the portable terminal and the wireless communication substrate 34 can wirelessly communicate via the antenna section 35 via the internet. Therefore, the user performs setting such as changing the temperature setting of the storage chamber of the refrigerator 100 and starting the adjustment operation from the inside or the outside. Then, if the settings are completed, the refrigerator 100 can transmit a report of the completion of the settings to the user's mobile terminal via the antenna unit 35 and the internet from the wireless communication board 34.

The humidity sensor board 33 and the wireless communication board 34 shown in fig. 5 are housed in a board housing portion 36 made of resin. The substrate accommodating portion 36 is disposed on the top surface portion 2 a. The substrate housing portion 36 includes a humidity sensor substrate housing portion 36a disposed on the side (front side) of the refrigerating chamber door 7. Further, in the substrate housing portion 36, a wireless communication substrate housing portion 36b is integrally formed behind the humidity sensor substrate housing portion 36 a. As shown in fig. 5, the board storage 36 is disposed near the right hinge 22. The humidity sensor substrate housing portion 36a and the wireless communication substrate housing portion 36b of the substrate housing portion 36 are disposed so as to close the opening portion 2c (see fig. 4) disposed on the top surface portion 2a in a state of entering the inner box 3 in the direction (inward). Further, a part of the substrate accommodating portion 36 is disposed to overlap an upper portion of the top surface portion 2 a.

Fig. 6 is a sectional view of a main portion of fig. 5 viewed from a VI-VI direction. As shown in fig. 6, the humidity sensor substrate housing section 36a and the wireless communication substrate housing section 36b include: a portion arranged to overlap with an upper portion of the top surface portion 2 a; and a portion extending downward from the opening 2c and embedded in the foamed heat insulating material 4. The lower portion of the substrate accommodating portion 36 has a stepped shape. The substrate storage 36 has a partition wall 36f that partitions the humidity sensor substrate storage 36a and the wireless communication substrate storage 36b in the front and rear directions. In the present embodiment, the partition wall 36f abuts against the protruding piece 42 integrally formed with the right hinge cover 22a to partition the humidity sensor board housing 36a and the wireless communication board housing 36 b.

A humidity sensor 32 for detecting the indoor humidity is disposed in the humidity sensor substrate housing portion 36 a. The humidity sensor 32 is mounted on a humidity sensor substrate 33. The humidity sensor substrate 33 is supported by a rib formed integrally with the humidity sensor substrate housing portion 36a and is disposed substantially horizontally.

As shown in fig. 5, a connection terminal 33a is disposed on the humidity sensor substrate 33, and a wire 37a is connected to the connection terminal 33a via a connector 37 b. The wiring 37a is connected to the control board 30 (see fig. 3) of the top surface portion 2 a. The wiring 37a is embedded in the foamed heat insulating material 4, extends through the opening 2c (see fig. 6) of the top surface portion 2a and the hole 36d of the substrate housing portion 36, and is connected to the humidity sensor substrate housing portion 36 a.

As shown in fig. 6, the wireless communication board 34 is supported by the ribs of the holding portion 36e in the wireless communication board housing portion 36 b. The rib of the holding portion 36e is formed integrally with the wireless communication board housing portion 36b upward. The wireless communication board 34 is disposed apart from the top surface portion 2a by a predetermined size. An antenna unit 35 is disposed on the upper surface of the wireless communication board 34. When the antenna unit 35 is close to a metal member or the like in particular, radio wave interference may occur, and radio waves may cancel each other out and make communication with a mobile terminal or the like impossible. Therefore, it is necessary to secure a distance between the antenna portion and a substance having a high dielectric constant.

An opening 2c is disposed in the metal top surface portion 2a so that the distance between the antenna portion 35 and the top surface portion 2a as a metal member is a predetermined distance. Thus, no metal member is disposed at a position below the antenna portion 35. The distance L1 between the end face of the opening 2c and the antenna unit 35 is equal to or greater than a predetermined distance. In the present embodiment, L1 is more specifically not less than 16 mm.

The opening 2c may be disposed so that the entire projection surface of the wireless communication board 34 in the vertical direction faces the opening 2 c. On the other hand, if the opening area of the opening 2c is large, the strength of the outer box 2 may be reduced. Therefore, in the present embodiment, the top surface portion 2a is opened to at least a portion of the wireless communication board 34 that faces the projection surface of the antenna portion 35 in the vertical direction. The end of the opening 2c is disposed so that L1 is 16mm or more (16 mm in the example).

In the present embodiment, as shown in fig. 6, the wireless communication board 34 is disposed in an inclined state such that the antenna portion 35 of the wireless communication board 34 is distant from the top surface portion 2 a. In the present embodiment, for example, the antenna unit 35 is disposed above the center of the inclined wireless communication board 34 in the height direction. Thus, even in a narrow space, the distance between the antenna portion 35 of the wireless communication board 34 and the end portion constituting the opening 2c can be secured to 16 mm. The wireless communication board 34 is arranged as a rib held by the holding portion 36e, and is spaced from the peripheral edge of the opening 2c by a predetermined dimension.

As shown in fig. 5, the connection terminal portion 34a of the wireless communication board 34 is connected to the wiring 38a via the connector 38 b. The wiring 38a is disposed along the wireless communication board 34 so as to be disposed on a side portion of the wireless communication board 34. The connection terminal portion 34a of the wireless communication board 34 and the hole portion 36d of the buried wiring 38a are disposed at positions facing each other with the wireless communication board 34 interposed therebetween. The wiring 38a is configured to pass beside the wireless communication board 34 and be connected to the connector 38 b. That is, the wiring 38a extends along the side portion of the wireless communication board 34 and is connected to the connector 38 b. By disposing the wiring 38a in this manner, radio wave radiation from the wiring can be used for communication without any damage.

As shown in fig. 6, the wireless communication board 34 is disposed at an incline, the antenna portion 35 is disposed on the side of the wireless communication board 34 away from the top surface portion 2a, and the connection terminal portion 34a is disposed on the side of the wireless communication board 34 close to the top surface portion 2 a. Thus, since the antenna portion 35 is disposed apart from the metal top surface portion 2a, radio wave loss can be reduced. Further, since a space can be secured between right hinge cover 22a and wireless communication board 34, connection terminal portion 34a can be disposed in a limited space above the space covered by right hinge cover 22 a. Thus, the dead space can be eliminated to reduce the height size of the refrigerator.

The

wires

37a and 38a are arranged to extend from the control board 30 located behind the top surface portion 2a, embedded in the foam insulator 4, and extend through the hole portion 36d to the upper side of the top surface portion 2 a. Further, the wiring connected to an operation board (not shown) embedded in the refrigerating chamber door 7 is arranged to pass through the inside of the refrigerating chamber door 7 and protrude outward from the hole portion 22c of the right hinge 22. As shown in fig. 5, the wiring is fixed by a wiring fixing portion 22 b. The wiring is connected to another wiring (not shown) arranged to extend from the control board 30 through the interior of the foamed heat insulating material 4 and to the outside of the hole portion 36 d.

The upper portions of the right hinge 22 and the board storage 36 are covered with a right hinge cover 22a (see fig. 4). Antenna portion 35 and right hinge cover 22a are disposed at a distance from each other such that the distance between antenna portion 35 and right hinge cover 22a is 3mm or more. Right hinge cover 22a is made of resin. By securing a distance to be a space between the antenna unit 35 and the dielectric member around the antenna unit 35 by the right hinge cover 22a made of resin, it is possible to prevent the occurrence of variations in the resonance frequency of the antenna unit 35 and suppress deterioration of radiation characteristics.

(embodiment mode 2)

In the present embodiment, a modified example of the peripheral structure of the top surface portion 2a of the refrigerator 100 will be described. Other configurations such as the entire configuration of refrigerator 100 are the same as those of embodiment 1.

Fig. 7 is an exploded perspective view showing an example of a holder wireless communication module according to embodiment 2. The holder wireless communication module 50 shown in fig. 7 is configured to be capable of being accommodated in the wireless communication board accommodation portion 36b (see fig. 6) after the wireless communication board 34 is fixed to the holder member 40 and assembled into a module.

The wireless communication board 34 is fixed to a holder member 40 that is a member different from the wireless communication board housing portion 36 b. After the wireless communication board is fixed to the holder member 40, the holder wireless communication unit 50 is fixed to the wireless communication board housing portion 36 b.

The holder member 40 is integrally formed by extending upward from the bottom surface of the holder member 40a substrate accommodating portion 40a that receives the back surface of the wireless communication substrate 34, a width regulating portion 40b that regulates the movement of the wireless communication substrate 34 in the width direction, and a pressing portion 40c that presses the wireless communication substrate 34 so as not to move upward. The wireless communication board 34 is mounted on the board housing portion 40a with the antenna portion 35 as an upper surface. The wireless communication board 34 is held by the holder member 40 such that the movement of both side portions of the wireless communication board 34 is restricted by the width restricting portion 40b and a part of the upper surface of the wireless communication board 34 is pressed by the pressing portion 40 c.

The wireless communication substrate 34 is disposed obliquely due to the substrate housing portion 40 a. Thus, the antenna portion 35 is disposed at a distance of 16mm or more from the end of the opening 2c formed in the metal top surface portion 2 a. The wireless communication board 34 has a substantially rectangular shape. In addition, the outer contour of the holder member 40 has chamfered portions 40d at least at 1 corner in a plan view.

The wireless communication board 34 is fixed to the holder member 40 in advance and assembled into a module, and then attached to the wireless communication board housing portion 36b of the top surface portion 2a of the refrigerator 100. When the assembled holder wireless communication unit 50 is mounted, the chamfered portion 40d of the holder member 40 can be arranged to correspond to the predetermined shape of the wireless communication board housing portion 36b, so that assembly errors can be prevented, and workability during manufacturing can be improved.

A relay harness 39 is provided between the connection terminal portion 34a of the wireless communication board 34 and the connector 38b (see fig. 5). The relay harness 39 includes a relay wire 39a, a relay connector 39b disposed at one end of the relay wire 39a, and a relay connector 39c disposed at the other end of the relay wire 39 a. The relay wiring 39a can be connected by fixing the wireless communication board 34 to the holder member 40 and connecting the relay connector 39b disposed at one end of the relay harness 39 to the connection terminal portion 34a in advance. This allows the connector 38b of the wiring 38a, which is embedded in the urethane resin foam heat insulating material 4 and extends to protrude outward from the top surface portion 2a, to be connected to the relay connector 39c disposed at the other end of the relay harness 39. Therefore, the wireless communication board 34 can be prevented from being damaged in the assembling process of the refrigerator, and the workability of the connecting operation can be improved.

Fig. 8 is a plan view showing another example of the holder wireless communication unit according to embodiment 2. The holder member 45 of the holder wireless communication unit 51 is configured to hold both the wireless communication substrate 34 and the relay harness 39 from below. The holder member 45 includes a substrate receiving portion 45a that receives the wireless communication substrate 34, and a harness receiving portion 45b that receives the relay harness 39. In the holder member 45, a substrate receiving portion 45a and a wire harness receiving portion 45b are integrally formed. Therefore, the holding force of the connecting portion of the connecting terminal portion 34a of the wireless communication board 34 and the relay connector 39b of the relay harness 39 can be maintained. Therefore, the holder wireless communication module 51 can be prevented from being damaged during connection work, assembly, and the like.

Fig. 9 is a plan view of a main portion periphery when the holder wireless communication unit of fig. 8 is disposed in the refrigerator, and shows a state where the holder member 45 is accommodated in the substrate accommodation portion 36. Fig. 9 shows a state where right hinge cover 22a is removed. The holder member 45 is assembled by housing the wireless communication board 34 and the relay harness 39 in advance, and connecting and fixing them to the holder member 45. Then, in this state, the holder member 45 is engaged with and fixed to the substrate storage 36.

The wiring 38a connected to the control board 30 of the main body 1 is embedded in the foam insulator 4 and is disposed to extend from the hole 36d of the top surface portion 2a to the outside. The holder wireless communication unit 51 is engaged with and fixed to the board housing 36 in a state where the wireless communication board 34 and the relay harness 39 are mounted in advance on the holder member 45, and is then connected to the relay wiring 39a of the relay harness 39. Therefore, workability in manufacturing can be improved, and breakage and the like of the holder wireless communication module 51 at the time of assembly can be prevented.

Fig. 10 is a sectional view of a main portion of fig. 9 as viewed from the X-X direction. The substrate storage 36 has a protrusion 36g protruding downward from the bottom surface of the substrate storage 36. The protruding portion 36g is disposed in a state of being fitted into an end surface portion of the opening 2c provided in the top surface portion 2a, and is in direct contact with the foaming and heat insulating material 4. The protruding portion 36g is disposed so as to protrude downward from the opening 2c, and the substrate housing portion 36 is fixed in close contact with the foaming and heat insulating material 4.

As shown in fig. 10, the wireless communication board housing portion 36b of the board housing portion 36 is used as a base portion, and the holder member 45 of another member is disposed above the wireless communication board housing portion 36b, and the wireless communication board 34 is held by the board housing portion 45a formed integrally with the holder member 45. In addition, the wireless communication substrate 34 is disposed obliquely by the substrate housing portion 45 a. Therefore, a predetermined dimension can be secured as a distance between the antenna portion 35 of the wireless communication board 34 and the top surface portion 2a as a metal member.

Further, by disposing in this way, the distance between the antenna portion 35 and the surrounding metal member having a high dielectric constant can be secured, and loss of radio waves can be suppressed.

The humidity sensor substrate housing portion 36a has the same configuration as that shown in fig. 6.

As shown in fig. 11, a cutout 41 serving as an outside air communicating means is disposed in the right hinge cover 22a, and a gap is partially formed between the right hinge cover 22a and the top surface portion 2a by the cutout 41. The cutout 41 is disposed at least at a position facing the wiring housing 36c and in the vicinity of the humidity sensor substrate housing 36 a.

Since the air inside right hinge cover 22a communicates with the outside air by disposing notch 41, condensation can be prevented from occurring inside right hinge cover 22 a. Therefore, the reliability of the substrate can be ensured, and the detection accuracy of the humidity sensor can be improved.

The configuration of the notch portion 41 in fig. 11 can be similarly applied to embodiment 1.

Hereinafter, the refrigerator 100 configured as described in the above embodiments will be described.

The refrigerator 100 includes a metal main body 1 and a refrigerator door 7 that can open and close a front opening of the main body 1.

The top surface portion 2a of the main body 1 includes a wireless communication board 34 having an antenna portion 35. The wireless communication board 34 is housed in a resin board housing portion 36 disposed on the top surface portion 2 a. The wireless communication board 34 is held so as not to contact the bottom surface portion of the board housing portion 36.

This can secure a distance between the dielectric member and the antenna unit 35, prevent a variation in the resonance frequency of the antenna unit 35, and suppress deterioration of radiation characteristics.

In addition, a holding portion 36e for holding the wireless communication board 34 may be disposed in the board housing portion 36. A space portion may be formed between the wireless communication board 34 and the top surface portion 2a, and the holding portion 36e may be disposed to extend upward from the board housing portion 36. This enables the antenna portion 35 to be spaced apart from the top surface portion 2a, which is a metal member.

Further, the top surface portion 2a may have an opening 2c, and at least the antenna portion 35 of the wireless communication board 34 may be disposed in the vertical projection plane of the opening 2 c. The substrate storage 36 may be disposed so as to cover the opening 2 c.

Accordingly, since the top surface portion 2a made of metal is not provided on the vertical lower surface of the antenna portion 35 and the opening portion 2c is covered with the substrate housing portion 36 made of resin, it is possible to prevent polyurethane as a heat insulator from leaking from the opening portion 2c while suppressing radio wave loss due to metal members.

The wireless communication board 34 may be disposed to be inclined with respect to the top surface portion 2a so that the antenna portion 35 is spaced apart from the top surface portion 2 a. Thus, since the antenna portion 35 is disposed apart from the metal top surface portion 2a, radio wave loss can be reduced.

The top surface portion 2a may include a humidity sensor 32 for detecting ambient humidity. The humidity sensor 32 and the wireless communication board 34 can be housed in 1 board housing portion 36. This can improve workability in manufacturing the refrigerator 100.

Further, the board housing portion 36 may be disposed in the vicinity of the right hinge 22 of the refrigerating compartment door 7, and the board housing portion 36 and the right hinge 22 may be covered by the same right hinge cover 22 a. This can improve workability in manufacturing the refrigerator 100.

In each embodiment, an example in which the opening 2c is disposed near the right hinge 22 has been described, but the opening 2c may be disposed near the left hinge 21 and covered with the left hinge cover 21 a.

As described above, according to the present invention, it is possible to provide a refrigerator that can reduce radio interference while ensuring a distance between a dielectric member and an antenna unit. Therefore, the present invention is not limited to the above embodiments, and can be applied to a household refrigerator, a commercial refrigerator, and the like.
