Description

  The present invention relates to a refrigerator having an illuminance detection function.

  Generally, a refrigerator has a high proportion of electric power used at home, and there is a strong demand to suppress the electric power used as much as possible. Therefore, the thing which enables a power-saving driving | operation using an optical sensor is proposed. For example, if the light sensor detects more than a predetermined illuminance, the customer will go to bed and open and close the refrigerator door when food is less than the predetermined illuminance. As described above, a power-saving operation, that is, an energy-saving operation, is performed by operating with less power than a normal temperature. At this time, the optical sensor is provided on the front surface of the door to detect the illuminance in the room. (For example, refer to Patent Document 1 and Patent Document 2). There is also an optical sensor provided on the upper surface of the refrigerator body to detect the illuminance in the room. (For example, refer to Patent Document 3).

  FIG. 10 shows a refrigerator described in Patent Document 1. This refrigerator is provided with an operation unit 102 at the lower front portion of the door 101, and the operation unit 102 is provided with a light receiving unit 103 of an optical sensor. FIG. 11 shows the refrigerator described in Patent Document 2, and an operation unit 102 is provided in a vertical direction at a side end portion of one door of the double door 101, and a light receiving unit 103 of an optical sensor is provided on the operation unit 102. It is provided. Further, FIG. 12 shows the refrigerator described in Patent Document 3, and the optical sensor 104 is provided on the upper surface of the refrigerator main body 105.

  In the conventional refrigerators described in Patent Documents 1 and 2, since the light receiving unit 103 for detecting the illuminance in the room is provided in the operation unit 102, the light receiving unit 103 is used by a memo or flyer that is routinely performed by the user. Can be prevented from being obscured, and the effect of saving power by reliably detecting the room illuminance can be expected. That is, in order to operate the operation unit 102, a memo or a flyer will be placed avoiding the operation unit 102. Therefore, if the light receiving unit 103 is provided in the operation unit 102, the light receiving unit 103 can be used as a memo or a flyer. The room illuminance can be reliably detected without being covered by a leaflet or the like.

  However, when the light receiving unit 103 is provided on the front surface of the door, first, the light receiving unit 103 is conspicuous and there is a problem that the appearance of the door, in other words, the design of the refrigerator is deteriorated.

  In addition, after the user purchases the refrigerator and sets the refrigeration conditions by operating the operation unit 102, the operation unit 102 is almost never operated, so that the operation unit 102 is covered. In many cases, memos and leaflets are pasted. For this reason, the effect of providing the light receiving unit 103 in the operation unit 102 cannot be obtained as expected, and there is a problem that the room illuminance cannot be detected accurately.

Such a problem can be solved by providing an optical sensor 104 on the upper surface of the refrigerator main body 105 as described in Patent Document 3, for example. However, the user sometimes places an object on the upper surface of the refrigerator main body 105, and the optical sensor 104 is obscured by the object. In this case as well, there remains a problem that the room illuminance cannot be detected.

  This invention is made | formed in view of such a subject, and provides the refrigerator which can detect indoor illumination intensity reliably, without impairing an external appearance design.

  In order to achieve the above object, the present invention includes a refrigerator main body and a door, and one of the doors is provided with a illuminance sensor on the lower end surface thereof as a double door and a lower end surface of the double door with the illuminance sensor. The upper end surface of the door facing the door is formed with a downward concave portion as a handle portion, and the illuminance sensor is arranged so that at least a part of the light receiving angle thereof faces outward from the handle portion of the downward concave portion.

  As a result, the illuminance sensor is not visible from the front of the door and can be kept well without damaging the front of the door, i.e., the appearance design of the refrigerator. Even if the cover is covered, external light reaches the door outer periphery from the lateral direction, so that it can be reliably detected.

  The present invention provides a highly energy-saving refrigerator that can reliably detect the illuminance in the room even if a memo or a leaflet is attached to the front of the door without damaging the exterior design, and can accurately perform power saving operation and the like. Can do.

  1st invention is equipped with the refrigerator main body, the several storage chamber provided in the said refrigerator main body, and the door which each opens and closes the opening part of the said storage chamber, and one of the doors which opens and closes the said storage chamber is a double door opening An illuminance sensor is provided on the lower end surface of the door as a type door, a downward recess is formed on the upper end surface of the door facing the lower end surface of the double door with the illuminance sensor, and the illuminance sensor The light receiving angle is arranged such that at least a part of the light receiving angle is directed outward from the handle portion of the downward concave portion.

As a result, the illuminance sensor is not visible from the front of the door and can be kept well without damaging the front of the door, i.e., the appearance design of the refrigerator. Even if the cover is covered, external light reaches the door outer periphery from the lateral direction, so that it can be reliably detected.

  According to a second invention, in the first invention, an upward concave portion is formed on a lower end surface of a door provided with an illuminance sensor to form a handle portion, and the illuminance sensor is incorporated into a part of the handle portion.

  Thereby, while an illuminance sensor can be rationally integrated using a handle part, it can arrange | position more difficult to see from the exterior, and can make the external appearance design of a refrigerator much more favorable.

  3rd invention is equipped with the refrigerator main body, the several storage chamber provided in the said refrigerator main body, and the some door which can each open and close the opening part of the said storage chamber, Each said door colors the front surface A transparent front plate with a layer is formed, and the outer peripheral portion of the transparent front plate is exposed as it is without being covered with a transparent front plate insertion portion, and the lower end surface of one of the doors faces upward In addition, an illuminance sensor is incorporated into a part of the handle portion, and a downward concave portion is formed at the upper end of the door immediately below the handle portion incorporating the illuminance sensor to form a handle portion. The light receiving angle of the illuminance sensor is configured to be directed outward from the handle portion of the downwardly recessed portion.

  As a result, even if there are multiple doors, the surface of the transparent front plate that forms the front of each door is flat without any protrusions due to the transparent front plate insertion part or handle, so the entire door surface is flat. It will be refreshing and good. In addition, since the transparent layer is positioned in front of the colored layer, the color is deepened and the texture is increased. And by incorporating an illuminance sensor into the door bottom handle of a refrigerator with high design that has such a flat feeling, power saving operation by the illuminance sensor can be performed while maintaining high design without causing the illuminance sensor to be recognized. It can be a possible energy-saving refrigerator.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, the front side of the door is made of a transparent front plate such as a glass plate, and the design is improved and the illuminance sensor is not conspicuous while improving the total design of the refrigerator. However, this does not limit the present invention.

BB sectional view, FIG. 8 is a CC sectional view of FIG. 6, and FIG. 9 is a control block diagram of the refrigerator.

  1 to 3, the refrigerator body 1 includes a metal (for example, iron plate) outer box 2 that opens forward, an inner box 3 made of hard resin (for example, ABS), the outer box 2 and the inner box 3. It consists of hard foaming urethane 4 filled and foamed between.

  The refrigerator main body 1 has a plurality of compartments formed therein. This storage room is located from the upper part of the refrigerator main body 1 to the refrigerator compartment 5, the switching chamber 6 located below the refrigerator compartment 5, the ice making chamber 7 juxtaposed to the switching chamber 6, the switching chamber 6, and the ice making chamber 7 below. The freezer compartment 8 and the vegetable compartment 9 located below the freezer compartment 8 are provided.

Further, the front surface of the refrigerator compartment 5 is opened and closed by double doors 10 and 10 (hereinafter referred to as double doors) so as to be opened and closed, and the front of the switching chamber 6, the ice making chamber 7, the freezer compartment 8 and the vegetable compartment 9. The part is closed openably and closably by pull-out doors 11, 12, 13, and 14 (hereinafter referred to as pull-out doors).

  There is a cooling chamber 16 on the back surface of the refrigerator body 1, and a cooler 17 that generates cool air and a blower fan 18 that supplies the cool air to each chamber are provided. In addition, a compressor 19 is provided at the back of the top of the main body of the refrigerator body 1, and a condenser (not shown), a heat radiating pipe 20, a capillary tube 21, and the cooler 17 described above are provided. A refrigeration cycle is configured by sequentially connecting in a ring shape, and a refrigerant is sealed in the refrigeration cycle to perform a cooling operation.

  Here, each of the doors 10 to 14 is foamed and filled with hard urethane like the refrigerator body 1 so as to have heat insulation properties, and its front surface is made of a transparent front plate such as a glass plate in order to further improve the design. It is.

  Hereinafter, the structure of the double doors 10 will be described with reference to FIGS. The doors 11 to 14 other than the double door type door 10 have the same configuration.

  4 to 8, particularly FIG. 6, reference numeral 23 denotes an inner frame which is located inside the refrigerator main body 1 and is formed of, for example, ABS resin. Reference numeral 24 denotes an edge frame bonded and fixed to the peripheral end face of the inner frame 23, and is formed of ABS resin. Reference numeral 25 denotes a transparent front plate (hereinafter referred to as a glass plate) such as a glass plate laminated on the edge frame 24 so as to cover the inner frame 23, and in this embodiment, it is formed of a glossy tempered glass plate. is there.

  As shown in FIG. 7, the glass plate 25 has a resin film 27 attached to the inner surface thereof with an adhesive 26, and a colored layer 28 made of a metallic pattern such as a picture pattern, for example, a hairline, is formed on the resin film 27. It is. As a result, the glass plate 25 becomes a glass plate with a colored layer.

  In this embodiment, the resin film 27 is made of polyethylene terephthalate having high transparency and high mechanical strength, and the colored layer 28 is formed on the side opposite to the glass plate 25 in the white system and on the glass plate 25 side in the gray system. It is formed. In the drawing, the case where it is formed on the side opposite to the glass plate 25 is shown.

  29 is a hard urethane filled and foamed in the space between the inner film 23 and the edge frame 24 on the surface of the glass plate 25 on the resin film 27 side, and the glass plate 25 together with the inner frame 23 and the edge frame 24 by foaming. The glass plate 25 is adhered to and held on the resin film 27 on the inner surface via the resin film 27. The outer peripheral edge portion of the glass plate 25 is exposed as it is, and is positioned slightly inside the end edge 24c of the edge frame 24 as shown in FIG. 8 and about 2 mm inside in this embodiment. That is, the glass plate is different from the configuration in which the glass plate insertion portion is provided in the edge frame like the conventional glass plate type door and the outer peripheral edge portion of the glass plate is inserted into the glass plate insertion portion to hold the glass plate. Holding.

  Therefore, in this configuration, it is necessary to reinforce the adhesion holding force of the glass plate 25 by the urethane foam 29. Therefore, in this embodiment, the foamed urethane 29 is configured such that the foam density at the outer peripheral portion is higher than the foam density at the central portion, and the adhesive holding force at the outer peripheral portion is larger than the adhesive holding force at the central portion. The foam density is made higher at the outer peripheral part, for example, by providing an air vent hole at a position corresponding to the foam outer peripheral part of the inner frame 23 so that the urethane foams into the core at the air vent hole part. This can be achieved. Furthermore, in this embodiment, the edge frame 24 and the glass plate 25 are bonded with a double-sided tape 30 as shown in FIGS.

On the other hand, as shown in FIGS. 4 and 5, the double doors 10 and 10 are formed with upward concave portions over substantially the entire length of the lower end surface of the edge frame 24 to form handle portions 10a and 10a. . Further, the pull-out doors 11 and 12 directly below the double doors 10 and 10, and the handle portions 11 a, 12 a, 13 a and 14 a of the freezer compartment 8 and the vegetable compartment 9 in the pull-out doors 13 and 14 are respectively pull-out types. A downward concave portion is formed on the upper end surface of the door edge frame 24. And the edge frame 24 which formed each said handle part 10a, 10a, 11a, 12a, 13a, 14a does not have a colored glass plate insertion part as already stated, but this each handle part 10a-14a is door end surface. The surface of the door group is a flat surface with a flat feeling because it is recessed and does not have a glass plate insertion portion.

  Here, as shown in FIG. 5, an illuminance sensor 31 is provided in the concave portion that becomes the handle portion 10a of one of the double doors 10 and 10. The illuminance sensor 31 is attached to a sensor substrate 33 of a unit frame 32 incorporated in a part of the handle portion 10a via a spacer 34. As is apparent from FIG. The drawer-type door located directly below 31, in this example, is arranged so as to face outward from the downward concave handle portion 15 constituting the handle portion 12 a of the drawer door 12. This is preferably arranged so that the entire area of the light receiving angle α is directed outward from the downward concave handle portion 15 constituting the handle portion 12a, but at least a part of the light receiving angle α is a downward concave shape constituting the handle portion 12a. What is necessary is just to arrange | position so that it may face outward from the handle part 15. For example, in this embodiment, an illuminance sensor with a light receiving angle of 60 ° is used, and a little more than half of the light receiving angle of 60 ° is arranged to face outward from the downward concave handle portion 15 constituting the handle portion 12a. However, depending on the sensitivity of the illuminance sensor 31, a smaller light receiving angle can be obtained.

  Further, this refrigerator is configured to perform a power saving operation based on the output from the illuminance sensor 31. That is, as shown in FIG. 9, when the output from the illuminance sensor 31 becomes less than a predetermined value (in the middle of the night when the user goes to bed and opens and closes the refrigerator door and hardly puts food in and out), the main body control unit 35 sets the set temperature. Is switched from the normal operation value to a slightly higher power saving operation value to control the compressor 19 and the blower fan 18 to perform the power saving operation.

  In this embodiment, the sensor board 33 also serves as an operation board. Although not shown, the sensor board 33 is formed in a strip shape long in the lateral direction of the lower end of the double door 10 and is provided with an operation unit such as a touch switch or a display unit such as an LED. Is incorporated.

  In the refrigerator configured as described above, since the illuminance sensor 31 is provided on the lower end surface of the double door 10, it is difficult to see from the front side of the refrigerator, and the design property is lowered like that provided on the front surface of the door. There is no. In particular, in this embodiment, the illuminance sensor 31 is incorporated in a part of the handle portion 10a formed of an upward concave portion provided on the lower end surface of the door 10, so that it can be rationally incorporated using the handle portion 10a. And it can arrange | position more difficult to see from the exterior, and can make the external appearance design of a refrigerator more favorable.

  Moreover, even if a memo or a leaflet is pasted on the front surface of the double door 10 incorporating the illuminance sensor 31, it does not cover the surface of the illuminance sensor 31 in close contact, and the lower end of the double door 10 and the drawer door Since the light reaches through the gap between the upper end of 12, the illuminance in the room can be reliably detected.

  In particular, in this embodiment, it is possible to greatly reduce the influence of pasting a flyer or memo. That is, when a memo or flyer is pasted on the lower end of the double door 10, the memo or flyer obstructs the opening / closing of the pull-out door 12 below the double door 10, so that the user can take a memo or flyer. This is because there is almost no possibility of pasting. Therefore, the room illuminance can be detected more reliably than when the illuminance sensor is provided on the side end surface of the double door 10.

  Further, even when the user's hand is wet with water when the door is opened and closed and the surface or side end surface of the double door 10 is wet, the water on the door surface or the side end surface is held by the handle at the lower end of the door. It can prevent reaching to the illuminance sensor installation part of the part 10a, and it can be made highly reliable without worrying about failure.

  Furthermore, since the illuminance sensor 31 is attached to the sensor substrate 33 of the unit frame 32 as a unit, the illuminance sensor 31 can be easily attached only by incorporating the unit frame 32 into a part of the handle portion 10a. Productivity can be improved.

  In addition, the refrigerator shown to each said embodiment has a glass plate insertion part in the surface part of the glass plate 25 which comprises the front surface of each door 10-14, even if each door 10-14 is multiple pieces. Since there is no protrusion by the handle portions 10a to 14a and the surface is only a flat surface of the glass plate 25, the entire surface of the door is clean and good with a flat feeling.

  In addition, the gap between the left and right doors of the double doors 10 and 10 can be narrowed by providing the handle portions 10a and 10a in the lower end surface of the door so that it is not necessary to provide a handle portion between the left and right doors. The sense of unity and flatness of the left and right doors of the double doors 10 and 10 can be maintained well.

  Thus, by maintaining the unity feeling and the flat feeling between the left and right doors of the double doors 10 and 10 and the drawer doors 11 and 12 and the double doors 10 and 10, the design is further improved.

  Furthermore, in the refrigerator of this embodiment, since the transparent layer of the glass plate 25 is positioned in front of the colored layer 28 by applying the colored layer 28 on the inner surface side of the glass plate 25, the coloring color has a depth. In addition, the texture is increased and the colored layer 28 is formed on the resin film 27. Therefore, the colored layer 28 can be formed by a roller or the like. Thus, a fine pattern such as a hairline line that could not be obtained can be formed, and the design can be further improved.

  And, there is such a flat feeling, and by incorporating the illuminance sensor 31 in the form described in the above embodiments in a refrigerator with high design, the above-described flat feeling without making the illuminance sensor 31 conscious. It can be set as the energy-saving refrigerator which has high designability and can perform the power saving operation by the illuminance sensor 31.

  On the other hand, the refrigerator door is configured such that the foam density of the urethane foam 29 is higher in the outer peripheral portion than in the central portion of the glass plate 25, and therefore the adhesive force of the foamed urethane 29 is higher in the outer peripheral portion of the glass plate 25. It will be stronger. Thereby, the adhesive force between the resin film 27 of the glass plate 25 and the urethane foam 29 can be more reliably maintained and secured over a long period of time.

  That is, the outer peripheral portion of the foamed urethane 29 has a high foaming density, in other words, a skin layer that is very finely foamed, and therefore has a large adhesion area, and as a result, the resin film of the foamed urethane 29 and the glass plate 25. The adhesion density with 27 is high and strong. Therefore, even if the glass plate insertion portion is abolished, the glass plate 25 can be securely bonded to the urethane foam 29 over a long period of time.

Further, the door holds the glass plate 25 with the urethane foam 29 and at the same time, the outer peripheral portion of the glass plate 25 is bonded to the edge frame 24 of the inner frame 23 with the double-faced tape 30. In addition to bonding to the edge frame 24, the double-sided tape 30 is used. Therefore, the glass plate 25 with the colored layer to which the resin film 27 is attached is strongly bonded and held to both the urethane foam 29 and the edge frame 24, and the adhesive strength of the glass plate 25 is maintained over a long period of time. Can be ensured.

  In addition, since the double-sided tape 30 has the outer peripheral portion of the glass plate 25 bonded to the edge frame 24 of the inner frame 23, the water applied to the door enters the door inward from the door end and foams due to this water intrusion. The adhesion peeling between the urethane 29 and the glass plate 25 can be reliably prevented, and the adhesion and holding of the glass plate 25 can be ensured for a long period of time.

  That is, the refrigerator has a large temperature difference between the inside and the outside, and the end of the glass plate 25 of the door is affected by condensation and severe temperature changes due to the cold air from the inside when the door is opened and closed. Further, depending on the usage of the user, the door may be subjected to a severe impact during opening and closing, or the door including the glass plate 25 may overflow with water or juice when the stored items are put in and out. And if there is no glass plate insertion part which covers the said glass plate edge part by the use environment and the actual condition peculiar to such a refrigerator, the water etc. which hung on the door edge part will infiltrate into the door inside. It is easy to peel off from the urethane foam 29.

  Under such circumstances, in this embodiment, the glass plate 25 serving as the door end portion and the edge frame 24 of the inner frame 23 are bonded by the double-sided tape 30, so that the glass plate 25 and the edge frame are bonded. The double-sided tape 30 can reliably prevent water and the like from entering between 24 and the inside of the door. Therefore, water or the like can enter the door inward from the edge of the door to prevent the adhesive peeling between the glass plate 25 and the urethane foam 29 and maintain the adhesive strength between the glass plate 25 and the urethane foam 29 over a long period of time. can do.

  Furthermore, in this embodiment, as shown in FIG. 7, a portion of the edge frame 24 of the inner frame 23 located on the lower end surface of the glass plate 25 does not jump forward from the front surface of the glass plate 25. Since the glass plate support piece 24d to be polymerized is positioned on the lower end surface of the glass plate, the glass plate 25 is supported by the glass plate support piece 24d of the edge frame 24 of the inner frame 23. Therefore, even if the peeling of the glass plate 25 may partially occur due to the deterioration of the adhesive force of the glass plate 25 by the urethane foam 29, an abnormal situation such as the dropping of the glass plate 25 is surely prevented. This will greatly improve your sense of security. Further, since the glass plate support piece 24d of the edge frame 24 does not protrude from the front surface of the glass plate, it is not visible from the front surface of the door as in the glass plate insertion portion, and the design and the flat feeling of the entire surface can be maintained. .

  Furthermore, in this embodiment, as shown in FIG. 8, the glass plate 25 has its outer peripheral edge located slightly inside the edge 24c of the edge frame 24. The entire outer peripheral edge is protected by the edge 24c of the edge frame 24. Therefore, for example, it is possible to prevent the outer peripheral edge of the glass plate 25 from hitting a certain object and cracking at the time of door transportation on the production line or door replacement service at the user's house.

  Even if some external force is applied to the glass plate 25 and it should break, this glass plate piece is adhered to the resin film 27 to prevent scattering, and safety in the event of an emergency is also improved. To do.

  As mentioned above, although main embodiment of this invention was described, the said embodiment was shown as an example in implementing this invention, and can be variously changed within the range which achieves the objective of this invention. Needless to say.

For example, the glass plate may be replaced with a transparent resin plate, which makes it possible to further secure the adhesive strength by reducing the weight and to reduce the cost. Moreover, although the resin film with a colored layer was stuck on the glass plate and it was set as the glass plate with the colored layer, this abolished the resin film and formed a colored layer directly on the glass plate as a glass plate with a colored layer. Is also good.

  As described above, the present invention is capable of reliably detecting the illuminance in the room even if a memo or a leaflet is attached to the front of the door without deteriorating the appearance design, and is highly energy-saving so that power saving operation can be performed accurately. It can be used as a refrigerator, and can be widely applied to commercial refrigerators and wine coolers.
