technical field

The present invention relates to a refrigerator provided with a single-opening revolving door provided with a glass material on the surface of the door.

Background technique

In recent years, products including a glass material on the surface of a door of a refrigerator have been commercialized. In these conventional examples, it is possible to coordinate with the interior of the kitchen by performing various printings on the backside of the glass material. In addition, by forming the surface with a glossy surface unique to glass materials, it is easy to obtain a refrigerator with excellent design while maintaining cleanliness and a sense of luxury.

A refrigerator having such a glass material has a handle structure of a revolving door that does not impair the opening and closing function of the door and is excellent in the design of the glass material. For example, Patent Document 1 discloses a handle structure in which, in a side-by-side opening and closing door, a concave portion for inserting a hand is formed in the frame, and an end portion of a tempered glass plate protrudes from the concave portion, and the protruding portion As a handle part for hand hooking. Thereby, it becomes a refrigerator provided with the handle excellent in design which produces the sense of continuity of the glass material of a door surface, without impairing the opening and closing function of a door.

In addition, a refrigerator is proposed in which the door surface is not made of glass, but a single-opening revolving door is provided with a design handle that creates a sense of continuity with the door surface. For example, Patent Document 2 discloses that a concave portion is provided on the left side of the surface of the refrigerator compartment door, and the lower half of the concave portion has a deep depth in the width direction so that fingers can be inserted in the left and right sides, and constitutes a substantially L-shaped handle portion. structure.

Patent Document 1: Japanese Patent Laid-Open No. 2012-207857

Patent Document 2: Japanese Patent Laid-Open No. 2004-69094

As shown in Patent Document 2, a refrigerator having a substantially L-shaped grip-type handle on the front of the door is difficult to open and close with left and right hands. Specifically, in a refrigerator with a handle on the left side as viewed by the user, the right hand is usually used to hook the hand in the recessed portion to open and close. If the grip is reversed, it is difficult to hook the hand.

In addition, a partial enlarged sectional view of a refrigerator having a handle provided with another member shown in FIG. 8 on the surface thereof will be described in which a member different from the refrigerator housing made of glass is provided on the surface of the handle. When the hand is hooked to the handle 100 and the force N1 for opening and closing the door is applied, a larger force N2 is applied near the boundary between the grip portion, that is, the handle 100 and the support frame 101 supporting the handle. In addition, due to the repeated bending stress in long-term use, the breakage of the part where the stress is concentrated, or the deviation or deflection of the bonding interface between the frame of the handle 100 and the different material 102 on the surface causes the peeling of the different materials. In these cases, when the support frame is thickened, there is a problem in that the space for the hand to be inserted becomes small, which impairs operability.

The hand insertion recess 7 is provided continuously from the upper part of the door 4 a to the lower part of the door 4 b, and is a recess for separating the glass plates 5 and 6 on the surface of the door 4 . The glass plates 5a and 5b are provided on the front side on the left side in a front view, that is, on the opposite side to the rotation axis R, and are arranged on the front side of the first and second handle parts which will be described later. On the other hand, the glass plates 6a and 6b are provided on the front side on the right side, that is, on the rotation axis R side, in a front view.

By providing a glass material, in addition to being able to perform processing such as back painting to express various expressions, since the surface is glossy, it is also possible to provide a refrigerator with excellent appearance. In addition, in this embodiment, since it is a structure using four glass plates, design variation can be increased by combining glass, and the degree of freedom of design can be enlarged. In addition, when the back of the glass plates 5a, 5b has functional functions such as handles and operation parts, by providing glass plates with different decorations from the glass plates 6a, 6b (for example, reflector type or transparent type), it can be clearly defined. to clearly understand the differences in their respective functions, thus improving visibility.

In addition, in this embodiment, glass plates 5a, 5b and glass plates 6a, 6b are respectively provided on the surfaces of opening and closing doors 4a, 4b via hand-in recessed portion 7, but the structure is not limited thereto. For example, as a structure in which a recess is provided only at a portion where a second handle described later is provided, a single glass plate provided with only the portion where the recess is cut may be used.

As shown in FIG. 2, the refrigerator 1 has first handles 9a, 9b formed of recesses on the left side of the opening and closing doors 4a, 4b, that is, on the side where the glass plates 5a, 5b are provided.

In addition, in this embodiment, it is the structure of the recessed part longer than 9a up and down of the 1st handle part 9b. Usually, the refrigerator compartment 3 has a larger capacity and a higher height than the freezer compartment 2, and the handle 9b is provided at a lower position in view of users of various heights, thereby improving convenience. The same effect can be said for the second handle part described later. Of course, it is not limited thereto, and can be appropriately changed according to the height of the entire refrigerator main body and the height ratio of the freezer compartment and the refrigerator compartment.

In addition, in this embodiment, from the viewpoint of maintaining the thermal insulation properties, a recess is provided in a part, but it is also possible to provide a handle that can be hooked by the hand anywhere by forming the recess from top to bottom. department.

As shown in Fig. 1 and Fig. 3, in front of the opening and closing doors 4a and 4b of the refrigerator 1, a continuous hand-in recessed part 7 is formed from top to bottom. The hand-in recessed part 7 and the second handle part will be described using Fig. 4 10 relationships. 4 is a partially enlarged cross-sectional view of the door of the refrigerator according to Embodiment 1 of the present invention, in which (a) is a cross-sectional view along line A-A, and (b) is a cross-sectional view along line B-B.

As shown in Figure 4(a), the hand-extending recess 7 is disposed between the glass plates 5a and 6a, and the position of the A-A line section in Figure 1 is relatively high, so the above-mentioned first handle 9a is not provided. On the other hand, as shown in Figure 4 (b), at the lower position of the B-B line cross section, a first handle portion 9a is provided, and has a back surface facing the glass plate 5a, which communicates with the hand into the recessed portion 7, That is, the second handle portion 10a is formed by the concave portion on the side of the first handle portion 9a. In addition, the opening and closing door 4b side also has the second handle part 10b of the same structure, but the description is omitted.

The user can hook the left hand on the handle 11 on the glass plate 5a side of the first handle portion 9a to open and close the opening and closing door 4a, and can insert the right hand into the recess 7 and hook the hand on the second handle portion 10a. The opening and closing door 4 is opened and closed on the handle 12 on the side of the glass plate 5a. Moreover, the hand insertion recessed part 7 has the shape which has a circle toward the glass plate 5a, and by having this shape, insertion of a finger can be smoothly guided.

As one of the characteristics of this invention, the support|pillar part 13 is provided between the 1st handle part 9a and the 2nd handle part 10a. And the glass material 5a which is a translucent material is provided in the front surface of the 1st handle part 9a, the 2nd handle part 10a, and the pillar part 13 in these front surfaces. In this embodiment, the bonding method of the glass material 5a and the door 4a first utilizes adhesive components such as double-sided tape to be temporarily fixed on a part of the frame body 14 of the opening and closing door 4a, that is, the handles 11 and 12, to the opening and closing door 4a. Polyurethane foam heat insulating material is injected inside, and the inside of the pillar portion 13 is also filled, and the foam heat insulating material is bonded to the glass material 5a to perform final fixing. By having the handles 11 and 12 as the frame body 14, the glass material 5a can be temporarily fixed, so even if a foam insulating material is injected, the opening and closing door 4a and the glass material 5a can be adhered tightly while suppressing distortion. In addition, since the polyurethane foam heat insulating material and the glass material 5a are surface-bonded, there is an effect of absorbing impact, and even if the glass breaks, scattering of glass shards can be suppressed.

In addition, by providing the strut portion 13 between the first handle portion 9a and the second handle portion 10a, and setting the glass plate 5a in front of them, for example, when using the second handle portion 10a to open and close the door, even if applied Force, since the distance between the fulcrum and the force point is shorter than that of the case where there is a support portion on the side (for example, FIG. 8 ), the applied force can be reduced. In addition, by providing the first grip portion 9a, it is possible to disperse the action of the force applied to the second grip portion 10a. It is possible to reduce deviation and deflection of the surface handle frame and other materials caused by bending stress and shearing force on the glass plate. Therefore, a thinner material and a less rigid material can be used, so that the vertical dimension of the handle can be further increased, and a convenient handle portion that is easy to insert fingers can be provided.

In addition, according to the above structure, since the first handle portion 9a formed by the concave portion is provided on the side surface of the opening and closing door 4 opposite to the rotation axis R, the hand insertion concave portion 7 formed by the concave portion is formed on the front of the opening and closing door 4, and, A second handle portion 10a is formed in communication with the hand insertion recess 7 and is formed by a recess on the side opposite to the hinge portion 5 of the opening and closing door 4a, so the opening and closing door can be opened and closed from both left and right sides, thereby improving convenience. , In addition, since the handle is provided in the recessed part on the front and the side, it does not protrude forward, and space saving can be realized during arrangement.

In addition, in recent years, from the viewpoint of universal design, it is required that anyone can use it fairly and have a higher degree of freedom in use. By providing the first handle part 9a and the second handle part 10a, the Using it, it is possible to provide a refrigerator corresponding to the characteristics of various hands. In addition, there is also a type provided with a grip attached to the front of the refrigerator door as a handle usable from both left and right sides. However, in comparison with this, in the present application, the number of working steps and the number of parts can be reduced in the manufacturing process, and the cost can be suppressed. In addition, if the handle protrudes, additional packaging is required at this location, and the vertical dimension at the time of packaging becomes longer. On the other hand, as shown in this embodiment, the front surface can be made substantially flat, and packaging costs can be reduced without special packaging, and since the vertical dimension can be reduced accordingly, the number of storage and transport units can be increased.

5 is a partially enlarged cross-sectional view along line B-B of a modified example of the refrigerator according to Embodiment 1 of the present invention. In this modified example, the lateral width L2 of the second handle portion 10a is longer than the lateral width L1 of the first handle portion 9a. For example, as an example of dimensions, it is considered that the lateral width L1 is 20 mm to 30 mm, and the lateral width L2 is 30 mm to 40 mm. L1 is designed to be able to insert fingers around the distal interphalangeal joint called the first joint, and L2 is designed to be able to insert fingers around the proximal interphalangeal joint called the second joint.

Generally, the revolving door of a refrigerator is provided with a resin-made gasket containing magnets around the back surface, and is structured so as to be in close contact with the main body of the refrigerator so as not to be accidentally opened. When opening and closing the revolving door, not only the force of rotating the door but also the force of peeling the liner from the refrigerator main body is required. Therefore, a larger force is required for opening and closing on the inner side of the hinge than the side. Therefore, by increasing the lateral width L2 of the second handle portion 10 , it is possible to insert a finger deeply, and further apply a force for opening and closing the door 4 .

Another feature of the present invention is the point where the finger hook portion 20 is provided. Hereinafter, this feature point will be described using FIG. 6 . Fig. 6 is a partial enlarged view of the door provided with the finger hook in the refrigerator according to the embodiment of the present invention.

In recent years, products with glass material on the surface of the door of the refrigerator have been commercialized, which can be coordinated with the interior decoration of the kitchen, and the surface is formed of a glossy surface unique to glass material, and it is a high-end refrigerator with excellent design . However, when pollutants such as fingerprints adhere to the front of the door, there is a problem that these pollutants are more conspicuous due to the glossy surface unique to glass materials.

In addition, as in the present invention, when opening and closing a door with a handle portion provided with recesses along the upper and lower sides, the index finger to the little finger all enter the recess, but usually, the thumb is free to move outside, so there is a problem when opening and closing. The front of the glass is pressed with the thumb, and contamination is attached due to touching.

Therefore, in the present invention, the finger hook portion 20 having a surface inclined toward the first handle portion 9a is provided on the second handle portion 10a side of the glass material 5a. In this embodiment, the finger hook portion 20 is integrally formed with the frame body 11 , but it can also be provided as a different component.

With this structure, when putting a hand into the second handle portion 10a, by providing a place where a freely movable thumb can be attached, it is possible to prevent contamination such as fingerprints from adhering to the surface of the glass plate 5a. And, by setting the finger hook portion 20 whose surface is inclined toward the direction of the first handle portion 9a, when the opening action M is performed, the inclined surface is provided opposite to the direction of the action, so it is easier to hold the thumb and apply force. shape.

In addition, as another modified example, as shown in FIG. 6( b ), an opening and closing door 4 a having a finger hook 20 having a surface inclined toward the hand insertion recess 7 is also conceivable. This shape takes into account the range of movement of the thumb, that is, it is a shape that is easier to attach since the inclined surface is provided in the direction in which the thumb is extended.

Moreover, as another modified example, as shown in FIG.6(c), the finger hook part 20 which has a concave surface is also conceivable. With this structure, the thumb is easy to hold and apply force during the opening and closing operation, and since the inclined surface is provided in the direction in which the thumb is extended, it has a shape that is easier to attach.

In addition, in this modified example, the finger hook part 20 provided only in the 2nd handle part 10a side was demonstrated. This is because, when opening and closing the revolving door, not only the force to rotate the door is required, but also the force to peel the resin-made magnet-filled liner from the refrigerator main body is required. The second handle portion 10b on the inner side closer to the rotation axis R requires a larger force for opening and closing. Therefore, it is provided in the structure which makes it easy to attach a thumb to the 2nd handle part 10a side of the glass plate 5a by applying force. However, of course, a structure in which a similar finger hook portion is provided on the first handle portion 9a side may also be used.

As one of the features of this embodiment, a touch panel type operation unit 101 is provided between the pillar portion 13 and the glass material 5a. The operation unit 101 includes a film 102 printed with display characters such as operation buttons, a detection unit 103 for detecting changes in electrostatic capacitance, a substrate 104 equipped with an automatic control unit including a microcomputer, and a substrate isolated from the foam heat insulating material in the opening and closing door 4a. Housing 105.

By having the pillar portion 13, a thick operation portion can be provided at this position. With this structure, in order to open the door, insert the index finger to the little finger into the handle, use the thumb to operate the touch panel, and use one action to open and close the door, and simultaneously provide opening and closing assistance or other functions.

As the function of the touch panel type operation unit 101, for example, there is a door opening and closing assisting unit for opening and closing the door by the operation of the operation unit in the opening and closing door, and it is considered that the operation of the operation unit can assist mechanical door opening and closing. Function. Therefore, when the door is heavy due to the increase in the size of the refrigerator, it is not necessary to apply a large force, and since the hand enters the handle, even if the door is opened and closed mechanically, a reasonable and natural movement can be used. Open and close the door.

In addition, this invention is not limited to the said Example, Various modification examples are included. For example, the above-mentioned embodiments have been described in detail for the purpose of explaining the present invention clearly, but are not limited to the configurations provided with all the described configurations.
