Description

Luminous shelf assembly and refrigerator with same

Technical Field

The present invention relates to a refrigerator, and more particularly, to a refrigerator having a light emitting shelf assembly capable of illuminating a compartment of the refrigerator.

Background

In the related art, a ceiling lamp and a side lamp are generally provided in an interior of a refrigerator as an interior lighting system of the refrigerator. In the refrigerator having such an in-compartment lighting system, if too many foods are stored, particularly, when too many foods are stored in the middle upper portion of the refrigerator, there is a possibility that the in-compartment lower portion of the refrigerator may be insufficiently illuminated because the illumination light from the ceiling lamp and the side lamp is blocked by the foods, causing a user to have difficulty in distinguishing the state of the foods stored in the in-compartment lower portion of the refrigerator.

In addition, since the size of the conventional refrigerator tends to increase with the development of life and technology, if the interior lighting system of the related art is still used with the development of the size of the refrigerator, there is a problem that lighting is insufficient in both the depth direction and the vertical direction of the refrigerator. In particular, since the vegetable room frequently used is generally disposed at the lowermost portion in the refrigerating chamber of the refrigerator, it is necessary to recognize food in the vegetable room with more illumination brightness when the refrigerator is used in a large size.

At this time, if the overall illumination brightness in the refrigerator is improved by increasing the brightness of the top and side lamps, a user may feel dazzling because a local brightness is excessively bright at the top and side portions. In addition, some opaque and light-reflective foods, for example, plastic-packaged foods, are generally stored in the refrigerating chamber of the refrigerator, and if the foods are placed in the middle of the optical path of the illumination light, the foods may block the illumination light, so that even if the brightness of the dome lamp and the side lamp is intentionally increased, the illumination light does not reach the vegetable chamber or the like located at the bottom of the refrigerating chamber, and thus the act of increasing the illumination brightness of the dome lamp and the side lamp only causes an endless waste of energy.

In addition, compared with other articles in the refrigerator, the articles stored in the vegetable chamber are usually fruit and vegetable foods such as vegetables, fruits and the like which are easy to deteriorate and have short shelf lives, and when the fruit and vegetable foods are distinguished, the freshness of the fruits and vegetable foods is usually distinguished by the appearance condition, the color and the like of the fruits and vegetable foods. In this case, if the freshness of the fruit and vegetable food cannot be accurately determined from the appearance, color, and the like of the food due to insufficient light, there is a possibility that the freshness is erroneously determined, and the expired food or even rotten and deteriorated food is stored in the refrigerator. This is not only disadvantageous for finishing and cleaning in the refrigerator, but also causes waste of food. Therefore, it is important to clearly see the foods of vegetables, fruits and other fruits stored in the vegetable room and accurately identify the freshness of the foods, so that there is a more urgent need for an illumination system that can provide more illumination brightness for clearly and accurately identifying the freshness of the foods in the vegetable room.

Detailed Description

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of a refrigerator 100 of the present invention. Fig. 2 is a side sectional view showing a refrigerating part 101 of the refrigerator of the present invention.

As shown in fig. 1, a portion of a refrigerator 100 according to the present invention having a left and right side-by-side split door at an upper portion thereof is a refrigerating portion 101, and portions of two drawer types at a lower portion thereof are freezing portions (106, 107). In fig. 1, the refrigerating unit 101 is in a door-open state, and the freezing

units

106 and 107 are in a closed state.

Next, referring to fig. 1, the interior of refrigerating unit 101 is divided into a plurality of storage compartments, and the compartments are respectively defined by their functions (cooling temperatures) as refrigerating compartment 102, vegetable compartment 103 provided below refrigerating compartment 102, drying compartment 104 provided to the left below vegetable compartment 103, and small temperature-changing compartment 105 provided below vegetable compartment 103 and on the right side of drying compartment 104, and capable of changing the temperature in the compartment. Here, the left-right direction refers to a left-right direction based on a position where a user faces a refrigerator door to take out a stored article.

The freezing section is a two-layer drawer type storage room, and includes a large temperature-varying chamber 106 located below the drying chamber 104 and the small temperature-varying chamber 105, and a freezing chamber 107 located at the lowermost layer.

A split heat insulating door is provided in a front opening of the refrigerating unit 101, and a foam heat insulating material such as urethane is filled in the door. The split insulated door is shown in an open position in fig. 1.

Further, heat insulating doors are provided at front openings of the large temperature changing chamber 106 and the freezing chamber 107, that is, at the front sides of the drawers.

Specifically, the refrigerator 100 of the present invention includes a refrigerating unit heat insulating door, a large temperature changing chamber drawer door, and a freezing chamber drawer door. The storage chambers are sealed by the heat insulating doors, so that cold air does not leak.

The refrigerator 100 of the present invention is an insulated cabinet in which a heat insulating material such as hard foamed urethane is filled between an outer box and an inner box. The insulation box insulates the inside of the insulation box from the surroundings.

The refrigerating chamber 102 is a storage chamber maintained at a low temperature to the extent that it is not frozen for refrigerated preservation. The specific temperature is usually set to 1 ℃ to 5 ℃. As shown in fig. 1 and 2, the refrigerating compartment 102 is a space divided into three parts by three layers of shelves, but the number of shelves and the number of divided spaces are not limited to three, and more shelves and shelf frames may be provided as necessary to adjust the space in the refrigerating compartment 102, or the whole refrigerating compartment 102 may be formed as a large space without providing the shelves and shelf frames. In the refrigerating part 101, the refrigerating chamber 102 occupies a space from the top to the bottom as a whole.

As shown in fig. 1 and 2, in the present invention, the vegetable compartment 103 is provided below the refrigerating compartment 102, i.e., below the lowermost shelf of the refrigerating compartment 102. The vegetable room 103 is a storage room generally formed of a drawer-type transparent box or the like, and stores fruits and vegetables. The vegetable compartment 103 in fig. 1 is divided into two compartments, i.e., left and right compartments, but this configuration is merely an example, and the vegetable compartment may be integrally formed as a single vegetable compartment.

In the present invention, a drying chamber 104 is provided, and the drying chamber 104 is a refrigerated storage chamber for storing dried materials such as tea leaves and dried chinese wolfberry, for example, whose internal humidity is lower than that of the storage chamber such as the refrigerating chamber 102. Wherein the humidity inside the drying chamber 104 can be controlled.

The small temperature-changing chamber 105 is a storage chamber set to have the same temperature as or a temperature slightly lower than that of the refrigerating chamber 102. The operation panel (not shown) attached to refrigerator 100 can switch from the refrigerating temperature range to the freezing temperature range depending on the application, and the operation panel is biased toward the refrigerating temperature range.

A narrow space is provided between the heat insulation door of the refrigerating part 101 and the front surfaces of the vegetable compartment 103, the drying compartment 104, and the small temperature change compartment 105, and the space is connected to the refrigerating compartment 102 and is a part of the refrigerating compartment 102. That is, it can be seen that vegetable compartment 103, drying compartment 104, and small temperature-changing compartment 105 are provided in refrigerating compartment 102, and are independent of refrigerating compartment 102 because they have independent spaces.

The large temperature-changing chamber 106, which is a freezing section in the lower part of the refrigerator 100 according to the present invention, is also a storage chamber whose temperature may be the same as or slightly lower than that of the refrigerating chamber 102, and can be switched from a refrigerating temperature range to a freezing temperature range depending on the application by an operation panel (not shown) attached to the refrigerator 100. Generally, the minimum temperature of the large variable temperature chamber 106 is lower than the minimum temperature of the small variable temperature chamber 105, and is more biased toward the freezing temperature zone.

Furthermore, freezing room 107 is a storage room set at a freezing temperature band. Specifically, the temperature is usually set to-22 ℃ to-18 ℃ for cryopreservation. However, in order to improve the state of cryopreservation, the temperature may be set to a low temperature of-30 ℃ or-25 ℃.

Fig. 1 shows an example of a refrigerator of the present invention, but the present invention is not limited to the structure shown in fig. 1. For example, the vegetable compartment 103 may be used as a general refrigerating compartment without storing vegetables or the like; the drying chamber 104 and the small temperature-changing chamber 105 are respectively arranged at the left side and the right side, but the positions can be changed mutually; in addition, the number and positional relationship of the vegetable room 103, the drying room 104, and the small temperature changing room 105 may be interchanged. Among them, the vegetable room 103, the drying room 104, and the small variable temperature room 105 are preferable as storage rooms for refrigeration, so that the temperature is controlled together with the refrigerating room 102.

As shown in fig. 1 and 2, the refrigerator 100 according to the present invention includes 3 shelves in the refrigerating unit 101, but the number of shelves is not limited thereto and may be variously changed as necessary. In addition, a shelf provided on an upper surface of the vegetable room 103 shown in fig. 1 and 2 is formed as a shelf assembly a of the present invention described below. However, the shelf assembly a is merely an example of the shelf, and any shelf may be used as the shelf assembly a as needed.

The shelving assembly A of the invention will now be described in detail with reference to the drawings.

The shelf unit a of the present invention can be provided at any position of the shelf frame in the refrigerating section 101 of the refrigerator 100, and the position where the shelf unit a is provided on the upper shelf of the vegetable compartment 103 in fig. 1 and 2 is a preferred example, but is not limited thereto. As described above, the layout of the positions, the number, and the like of the vegetable room 103, the drying room 104, the small temperature change room 105, and the like in the refrigerating unit 101 is not limited to this, and various modifications may be made as necessary. For example, the vegetable compartment 103 may be provided at the lowest part of the refrigerating unit 101, the vegetable compartment 103 may be provided as one and the small temperature-changing compartments 105 may be provided as two, and the vegetable compartment 103 may be provided only at the lower part of the refrigerating unit 101 without providing the drying compartment 104 and the small temperature-changing compartments 105.

In fig. 1 and 2, 3 shelves are provided in the refrigerating part 101 and the shelf located above the vegetable compartment 103 is set as the shelf unit a, but all of the 3 shelves may be set as the shelf unit a. In addition, only one shelf may be provided and set as the shelf assembly a, or 3 or more shelves may be provided and any one of the shelves may be set as the shelf assembly a as necessary, and various modifications may be made.

The structure of the shelving assembly a in accordance with the invention will now be described in detail with reference to the accompanying drawings. As shown in fig. 1 and 2, the shelf unit a will be described by taking as an example a case where the shelf unit a is disposed above the vegetable room 103.

Integral Structure of luminous shelf assembly

FIG. 7 is a partial cross-sectional view illustrating one embodiment of the illuminated shelving assembly A of the invention. As shown in FIG. 7, the shelf assembly A of the present invention comprises a transparent panel 1 as a shelf body and a light emitting part 2 having a light emitting body 2-2 located behind the rear end edge of the transparent panel 1. In the present invention, for convenience of understanding, an LED lamp is described as the light emitting body 2-2 and an LED substrate provided with the LED lamp is described as the light emitting part 2, but the present invention is not limited to this, and other light emitting bodies and light emitting parts than the LED lamp may be provided as necessary, and for example, an incandescent lamp, a fluorescent lamp, a general energy saving lamp, or the like may be used. In the following description, the LED lamp and the LED substrate are merely an example of the present invention.

Next, referring to fig. 7, the shelf unit a further includes a substrate cover (light emitter cover) 3 capable of accommodating the LED substrate 2 (light emitting part), a rear molding 4 capable of engaging with the substrate cover 3, and a frame 5 surrounding the transparent panel 1. The rear molding 4 has a coupling portion that can be coupled to the frame 5 and an engaging portion that can be engaged with the rear portion of the substrate cover 3, and the specific configuration of the coupling portion and the engaging portion will be described later.

In a preferred embodiment of the present invention, the LED substrate 2 is sealed and fixed by inserting the LED substrate 2 into the substrate cover 3 and engaging the rear portion of the substrate cover 3 with the engaging portion of the rear molding 4, and then combining the rear molding 4 in this state with the frame 5. Specific components thereof will be described in detail below.

[ transparent Panel ]

In the present invention, the material constituting the transparent panel 1 is not particularly limited as long as it is a material that can transmit light, and for example, glass, resin, or the like may be used. The transparent layer may be a transparent layer or a translucent layer or a partially transparent layer, and for example, the entire transparent panel 1 may be formed of ultra-white glass, or one surface of the transparent panel 1 may be formed as a frosted surface. In addition, in order to better implement the refraction and the diffuse reflection of the light, it is preferable to form a plurality of light guide points or patterns on the surface of the transparent panel 1 by using a method such as high-temperature light guide ink screen printing, chemical etching, laser engraving, sand blasting engraving, mold molding, or the like, or to add a highly light guide material or other kinds of scattering materials during the molding of the transparent panel 1. When the light guide points or the patterns are provided on the surface of the transparent panel 1, it is preferable to achieve the front-back uniformity of the illuminance by changing the density arrangement degree of the light guide points and the patterns. For example, the number of light guide points may be reduced as the light guide points approach the LED substrate 2, or the pattern may be thinned as the light guide points approach the LED substrate 2 and may be densified as the light guide points move away from the LED substrate. As an example, reference may be made to fig. 9. Fig. 9 is a partial schematic top view of a light-emitting shelf assembly having light-reflecting dots according to the present invention, showing an example of the manner in which the light-reflecting dots are disposed. As a specific example, d is in the range of 0.1mm to 1mm, preferably d is 0.4. + -. 0.05mm, and t/d is 1 to 20, where d is the light guide point diameter d and the light guide point interval t.

In addition, during the manufacturing, assembling and taking processes of the transparent panel and during the use process of the refrigerator, it is inevitable that stains such as fingerprints and oil stains occur on the surface of the transparent panel or stains are formed on the transparent panel due to residues of stored materials, and some of the fingerprints, stains and stains are difficult to remove, so that the rejection rate of products in the production process is increased, and the appearance effect of the products is also reduced, and especially when the light emitting part (LED substrate) 2 is lighted, the fingerprints, stains and stains become more obvious. In addition, in order to remove the marks, the user needs to repeatedly clean the transparent panel during the use of the refrigerator, thereby adding unnecessary trouble to the user.

In addition, since the light-emitting portion is disposed on only one side of the transparent panel, at a position far from the light-emitting portion, light may be attenuated, so that a case where one end of the transparent panel is too bright and the other end of the transparent panel is too dark occurs at both ends of the transparent panel, and a significant luminance difference occurs (for example, at the end where the light-emitting portion is located, the transparent panel is too bright, and at the end where a user is located, the transparent panel becomes dark due to attenuation of light).

In order to solve the above problem, as shown in fig. 10 and 11, it is preferable that, in the manufacturing process of the transparent panel 1, a plurality of light guide points 8 are formed on the surface of the transparent panel 1, and then, a printed layer 9 is further formed. That is, light guide 8 is sandwiched between transparent panel 1 and print layer 9. By such a structure that the light guide point 8 is formed on the surface of the transparent panel 1 and the printed layer 9 is further formed, thereby sandwiching the light guide point 8 between the transparent panel 1 and the printed layer 9, the reflection of light can be realized by the light guide point 8. Further, since the print layer 9 is further formed, stains or stains such as fingerprints and oil stains can be hardly found, and the stains or stains such as fingerprints and oil stains can be more easily removed. Further, it is preferable that the printed layer 9 is a frosted printed layer, so that stains or stains such as fingerprints and oil stains can be more easily found, and stains or stains such as fingerprints and oil stains can be more easily removed by the characteristics of the frosted printed layer.

In addition, as the light guide point, in order to obtain a light guide effect more favorably, it is preferable to use a high-temperature ink light guide point, and as the matte printing layer, it is preferable to use a high-temperature varnish containing a high-temperature varnish and a semi-transparent white high-temperature ink. In order to make the surface of the transparent panel emit light uniformly, the ratio of the high-temperature varnish to the semi-transparent white high-temperature ink is preferably adjusted to be within a range of 5% to 20% of the ratio of the semi-transparent white high-temperature ink when the frosted layer is printed.

The light guide dots 8 and the printed layer 9 may be provided on both surfaces of the transparent panel 1, and preferably, the light guide dots 8 and the printed layer 9 are provided on the lower surface of the transparent panel 1.

[ LED substrate (light-emitting part) ]

In the present invention, the LED board 2 has a substantially long strip shape, and includes a charged board portion 2-1 and an LED lamp (light emitting body) 2-2 formed thereon. The LED lamp 2-2 on the LED substrate 2 can be turned on/off by connecting a lead portion (not shown) of the charged substrate portion 2-1 to a refrigerator power supply (not shown) to form a closed circuit, and controlling the closed circuit by a control system (not shown) of the refrigerator.

The number of the LED lamps 2-2 on the LED substrate 2 is not particularly limited, and may be one or more, and in the present embodiment, the LED substrate 2 is described as having a plurality of LED lamps 2-2.

[ substrate covering Member (light emitting part covering Member) ]

In the present invention, the substrate cover 3 has a substantially hollow "square" shape in cross section, a housing portion 3-1 capable of housing the LED substrate 2 is formed inside the substrate cover 3, and a transparent surface 3-2 is formed at least on a surface of the substrate cover 3 facing the LED lamp 2-2 included in the LED substrate 2.

Further, it is preferable that a heat dissipation chamber 3-3 for dissipating heat from the charged substrate portion 2-1 and the LED lamp 2-2 included in the LED substrate 2 is further formed in the substrate cover 3 on the rear side of the housing portion 3-1, so that heat generated from the charged substrate portion 2-1 and the LED lamp 2-2 when the LED substrate 2 is lit can be dissipated by the heat dissipation chamber 3-3. The housing portion 3-1 and the heat dissipation chamber 3-3 may be partitioned by providing ribs 3-4 (protruding bars) or the like protruding inward in a direction opposite to each other at substantially middle portions of upper and lower inner walls of the substrate cover 3, and in this case, the LED substrate 2 may be held or engaged by the ribs 3-4.

As shown in fig. 7, the LED board 2 can be inserted into the housing portion 3-1 of the board cover 3 and held and fixed. In a state where the LED substrate 2 is inserted into the accommodating portion 3-1, the LED lamp 2-2 faces the transparent surface 3-2 of the substrate covering member 3, so that light emitted from the LED lamp 2-2 can be emitted toward the rear end edge of the transparent panel 1 through the transparent surface 3-2. As one example, the illuminance of the LED substrate can be set to 300 to 1000lm, preferably 480 to 800 lm.

Further, the substrate cover is preferably made of metal (e.g., aluminum) or the like, and the substrate cover can be reinforced in strength, so that the light emitting unit or the LED lamp can be fixed more firmly and with higher accuracy, and the light emitting unit or the LED lamp or the like is less likely to be deformed, and the emission direction of the light emitted from the light emitting unit is maintained in a correct direction, so that the illumination can be performed more favorably. In addition, heat dissipation can be performed better.
