Rollers 11b and 12b are provided.

  Next, the configuration of the outer box 5 will be described. The outer box 5 is formed by integrally bending the three surfaces of the left and right side surfaces and the lower surface, and has a concave lower three-surface member 13 as viewed from the front, an upper surface member 14 made of a resin member that forms the upper surface, and a resin that covers the rear surface. Five surfaces are formed by the back member 15 made of a member. A thermo module 16 for cooling the heat transfer plate 10 is fixed to the back member 15. The thermo module 16 is composed of a Peltier element, and a storage hole is formed in the rear wall of the heat insulating container 2 so as to penetrate the outer box 5 and the heat insulating material, leaving a metal plate constituting the heat transfer plate 10 of the inner box 4. The thermo module 16 is disposed in the hole. Further, an aluminum alloy heat transfer block 17 having good thermal conductivity is interposed between the thermo module 16 and the heat transfer plate 10 of the inner box 4, and the heat transfer block 17 is inserted into the heat transfer plate 10 of the inner box 4. The heat transfer surface portion of the thermo module 16 and the heat transfer plate 10 of the inner box 4 are joined via a heat transfer block 17 so that heat can be transferred. The heat transfer block 17 is integrally fixed to the heat insulating container 2 by injecting a heat insulating material. In addition, the thermo module 16 is fixed to the heat transfer block 17 by screws or the like from the rear side.

  Further, as shown in FIG. 3, a heat sink 18 is provided which is thermally conductively joined to the heat source side heat exchange surface portion of the thermo module 16, and the heat sink 18 is configured to exchange heat by circulating outdoor air up and down. A large number of aluminum fins are arranged in the vertical direction. In addition, the entire back surface of the heat insulating container 2 is covered so as to cover the heat sink 18, and electrical parts (not shown) and the like are accommodated outside the rear wall of the heat insulating container 2, and a ventilation path for cooling the heat sink 18 is formed. A back cover 19 is provided. The back cover 19 is formed in a substantially box shape with the front surface open, and the lower surface of the back cover 19 is inclined upward as it goes rearward, and a suction port 19a for taking in outside air from the lower surface is opened. Further, the upper surface of the back cover 19 is formed to be inclined downward toward the rear, and an exhaust port 19b is formed in the upper surface portion.

  Also, a blower fan 20 is provided inside the exhaust port 19 b, and the outside air sucked from the suction port 19 a below the refrigerator 1 passes through the heat sink 18 due to the rotation of the blower fan 20 disposed at the upper back of the refrigerator 1. The heat is exchanged so as to be discharged from the upper exhaust port 19b. A filter 22 is provided on the lower surface of the back cover 19 so that dust and the like mixed in the air flowing into the heat sink 18 can be removed. This filter 22 is attached to a dish-shaped drain pan 21 for storing drain water adhering to the inner surface of the inner box 4, and the filter 22 is also pulled out and removed by pulling the drain pan 21 forward of the refrigerator 1. it can.

  Next, the energizing lamp of the refrigerator 1 will be described. As shown in FIG. 4, an illumination (illumination device) 23 is provided at the upper part of the front of the center of the left and right sides of the heat insulating container 2 so that stored items such as food and drink can be easily seen at night when the front door 3 is opened. In this example, a single light emitting diode 23a (see FIG. 6) is used for the illumination 23, so that almost no power is consumed and parts that turn on and off the illumination by opening and closing the front door 3 are unnecessary. As described above, when a power source (not shown) is turned on in the refrigerator 1, the light emitting diode 23a is always lit. As shown in FIGS. 3 and 6, the front door 3 is provided with a light guide plate 24, which is a transparent resin member such as PS resin (polystyrene resin) or acrylic resin that transmits light, and is formed through the front door 3. Yes. For this reason, when the refrigerator 1 is turned on, the illumination 23 of the refrigerator 1 is turned on and the light guide plate 24 provided on the front door 3 shines to confirm at a glance that the refrigerator 1 is turned on. it can. Since the light emitting diode 23a has a high directivity and a narrow irradiation range, the light emitted from the light emitting diode 23a is difficult to reach depending on the arrangement location of the light guide plate 24. Therefore, the rear end 24a of the light guide plate 24 is connected to θ2 in FIG. As shown in FIG. 4, the light emitting diode 23a is disposed at a position within an irradiation angle of 60 °. The angle θ2 at which the rear surface side end 24a of the light guide plate 24 is disposed so as to face the light emitting diode 23a is suitable for passing light into the light guide plate 24 within the range of 40 degrees to 60 degrees as a result of the verification. ing.

  Moreover, the structure of this Embodiment is suitable for the refrigerator 1 utilized in the hospital room etc. of a small hospital with 10-40 liters of accommodation items, such as food and drink.

  As described above, according to the first embodiment, the front door 3 is provided with the light guide plate 24 of the transparent resin member that transmits the light of the illumination 23, and the light guide plate 24 is formed through the front door 3. It can be confirmed at a glance that the refrigerator 1 is powered by turning on the light guide plate 24 arranged on the surface of the front door 3. Further, since the operation of the refrigerator 1 can be confirmed by the light guide plate 24 by the light emitting diode 23a that illuminates the interior, it is not necessary to separately provide a dedicated light emitting diode for confirmation and the like, which can be configured at low cost. . Further, in this example, the portions other than the light guide plate 24 of the front door 3 constitute the refrigerator 1 so that when the front door 3 is closed, light from the light emitting diodes 23a is transmitted and cannot be seen from the outside. Moreover, although the thickness dimension of the front door 3 shown to E dimension of FIG. 1 is based also on heat insulation performance in the small refrigerator 1, it is comprised by the thickness of the range of about 30 mm to 70 mm.

The first embodiment of the present invention will be described in more detail.
First, the illumination 23 will be described. As shown in the cross-sectional view of FIG. 6, the white light emitting diode 23a is arranged with the light emitting portion facing downward so that the inside of the storage case 9 pulled out can be easily illuminated, and as shown by θ1 in FIG. As shown by 23c, it may be arranged so as to be tilted forward in an angle range of 0 to 20 degrees with respect to the vertical. In FIG. 6, the angle is θ1 = 10 degrees. Further, in FIG. 6, the sections of the illumination cover 23b and the light guide plate 24 that serve to protect the light emitting diodes 23a are painted out so as to be easy to understand. However, as described above, colorless (completely colorless is difficult). Therefore, the light emitted from the light emitting diode 23a can be sufficiently transmitted.

  The light guide plate 24 is formed in a substantially flat plate shape, and includes a rear side end 24a through which light from the light emitting diode 23a flows, a light guide unit 24c through which the light passes, and a front side end 24b through which the light flows out. As described above, the light guide plate 24 penetrates the front door 3 back and forth from the rear side to the front side of the front door 3 and is exposed on the rear side of the front door 3 disposed in the vicinity of the illumination 23. It has a front side end 24b exposed on the front side of the front door 3 arranged below the position of the end 24a and the rear side end 24a, and is formed of a transparent resin member that transmits light, and a rear side end Since the light of the light emitting diode 23a of the illumination 23 flowing in from the lamp 24a is provided so that it can be seen through the front end 24b, the refrigerator 1 can be turned on and the cooling operation can be performed without opening the front door 3. There is an effect that it can be confirmed at a glance from the outside front of the refrigerator 1.

  Further, if the position of the rear end 24a of the rear surface side of the light guide plate 24 in the vertical direction is set within a range of an angle smaller than 60 degrees from the center position of the light emitting portion of the light emitting diode 23a as shown by θ2 in FIG. Further, since it is difficult to capture light when the angle is too small, it is preferable to arrange the rear side end 24a in the range of θ2 of 40 degrees to 60 degrees as the range, and the light from the light emitting diode 23a is transmitted to the light guide plate 24. The effect that it is easy to take in in the rear surface side edge part 24a is acquired.

  Next, the structure of the handle portion for opening and closing the front door 3 will be described. As shown in FIG. 8, FIG. 9, etc., the front door 3 is mainly injected between the front member 3a that forms the front side, the rear member 3b that forms the rear side, and the front member 3a and the rear member 3b. It is composed of a heat insulating material that is filled. As shown in FIGS. 1, 6 and the like, the front door 3 is provided with a substantially rectangular upper surface handle hole 3c formed widely on the upper left and right sides, and a user (not shown) of the refrigerator 1 can open. The front door 3 is pulled from above and the front door 3 is opened, and the storage case 9 is pulled out so that stored items such as food and drink can be taken in and out. Also, a substantially rectangular front handle hole 3d that is widely formed on the left and right sides is formed in the upper part of the front surface of the front door 3 so that the user can also pull the front door 3 by pulling the hand from the front. I have to. Further, the upper surface handle hole 3c and the front surface handle hole 3d are formed so as to communicate with each other through the through hole portion 3e as shown in FIG. It is formed so that it can be hung. Further, with this configuration, the front door 3 can be easily opened by pulling a towel or the like by passing a towel or the like (not shown) through the through hole 3e from the top handle hole 3c through the front handle hole 3d. This is effective for use in hospital hospital rooms. That is, a force that peels off the gasket 25 adsorbed by a magnet or the like so as to close the front door 3 or a certain amount of force to pull out the front door 3 when a large amount of food or drink is stored in the storage case 9 is heavy. Therefore, it is easy to use that the front door 3 can be easily opened by passing a towel or the like from the top handle hole 3c through the front handle hole 3d and pulling the towel.

  Further, the through hole portion 3e is connected to the lower side 3f of the front surface handle hole 3d and the rear side 3g of the upper surface handle hole 3c, as shown by θ3 in FIG. The light guide plate 24 is formed on an inclined surface of the through hole 3e that is formed as a part of the front surface of the front door 3 as viewed from the front handle hole 3d. A front-side hole 3h is formed to allow the front-side end 24b so that the front-side end 24b can be seen. Further, as shown in FIG. 9, on the back side of the front member 3a, a protruding portion 3j on which a locking portion 24d (see FIG. 7) of the light guide plate 24 is hooked and a front side end portion 24b of the light guide plate 24 are laterally arranged. A guide portion 3k that restricts movement is formed. In addition, a rear hole 3 i into which the rear end 24 a of the light guide plate 24 is fitted is also formed in the rear member 3 b of the front door 3.

  Next, the configuration of the light guide plate 24 will be described in more detail. As shown in FIG. 7, the light guide plate 24 is made of colorless (including nearly colorless) transparent PS resin or acrylic resin (especially easy to make PS resin), and is formed in a substantially flat plate shape. is there. The rear end 24a of the substantially rectangular shape arranged opposite to the light emitting diode 23a of the illumination 23 is a clean flat surface with few irregularities so that the light from the light emitting diode 23a can easily flow. Further, the rear surface side end 24a is formed to be inclined with respect to the light guide portion 24c so as to be fitted into the rear hole 3i formed in the rear member 3b of the front door 3 and to be exposed flush with the rear surface. Has been. Further, in this embodiment, the front side end 24b is also a beautiful flat surface with few irregularities so that light can be easily seen. Further, the front side end 24 b is formed so as to be fitted in a front hole 3 h formed in the front member 3 a of the front door 3 and to be exposed flush with the front side of the front door 3.

  The light guide plate 24 has a left and right width (shown in dimension C in FIG. 7) in the range of 10 mm to 30 mm, and a thickness of the light guide portion 24c (shown in dimension D in FIG. 7) in the range of 1 mm to 4 mm. As an example, a light guide plate 24 having a width C dimension of about 20 mm and a plate thickness D dimension of about 2 mm can be easily formed, and light from the light emitting diode 23a can be easily seen. Further, the angle (indicated by θ4 in FIG. 7) that is inclined downward as the light guide plate 24 is moved forward so that the front end 24b is located below the rear end 24a of the light guide plate 24 is horizontal. An angle range of 30 degrees to 50 degrees is preferable, and the light of the light emitting diode 23a entering from the rear side end 24a is moderately weakened and appears on the front side end 24b, so that the front side end 24b is not too bright. There is an effect that it is easy to see, and in the example of FIG. 7, θ4 is set to about 40 degrees. That is, when the light guide 24c is arranged horizontally and the light of the light emitting diode 23a is transmitted through the front surface of the front door 3, the light is too bright, for example, too dazzling for a person in a hospital room. Since the light guide 24c is slanted and formed long like this, this configuration in which light is moderately weakened while passing through the light guide 24c and appears on the front side end 24b is good. . Further, the positions of the rear hole 3i of the rear member 3b of the front door 3 and the front hole 3h of the front member 3a are the rear end 24a of the light guide plate 24 into which the light guide 24c is inclined and fitted. And the front end 24b are provided at the positions where they are arranged. Further, the reason why the light guide plate 24 is preferably formed in a flat plate shape so that the thickness D dimension is 1 mm to 4 mm is that the moldability of the resin material is good and easy to make. The reason why it is easy to see that the width C dimension of the light guide plate 24 is 10 mm to 30 mm is that if it is narrower than this, it is difficult to understand as a display, and even if it is wider than this, a large amount of material is required.

  The arrangement position of the light guide plate 24 in the left-right direction will be described. Like the illumination 23, the light guide plate 24 is provided at the left and right center positions, and the light from the light emitting diode 23a is transmitted from the rear surface side end portion 24a with the left and right arrangement positions of the light emitting diode 23a and the rear surface side end portion 24a being the same position. It is easy to get in. It should be noted that the left and right arrangement positions of the rear side end 24a are slightly shifted from the position of the light emitting diode 23a to the left and right (for example, about 10 mm on the left or about 10 mm on the right) if the light from the light emitting diode 23a enters. Also good.

  Then, the light from the light emitting diode 23a passes through the illumination cover 23b and flows in from the rear surface side end 24a of the light guide plate 24, and goes straight in the light guide 24c that is long and inclined, or in the light guide 24c. The light (light), which is moderately weakened and reflected while being reflected, can be seen at the front end 24b, and it can be easily confirmed that the refrigerator 1 is turned on and the cooling operation is being performed. That is why. Further, there is an effect that the position of the front side end 24b does not interfere with the formation of the handle portion (front handle hole 3d) of the front door 3. Further, since the light guide plate 24 is formed in a plate shape and the rear side end 24a and the front side end 24b are arranged in a wide rectangular shape on the left and right, the light of the light emitting diode 23a enters from the rear side end 24a. Since the front end 24b is also a rectangular shape that is wide on the left and right sides, it is easy to mold the resin, the transmitted light is not uneven, and a display that is easy to see is obtained.

  Further, the procedure for assembling the light guide plate 24 to the front door 3 will be described with reference to FIGS. The front end 24b is guided by the guide 3k so as to be hooked on the protruding portion 3j formed on the rear side of the front member 3a of the front door 3 and inserted into the front hole 3h. When the light guide plate 24 is locked to the front member 3a and the rear member 3b is superimposed on the front member 3a in this state, the rear surface side end 24a of the light guide plate 24 enters the rear hole 3i, and the light guide plate 24 is moved to the front side. It is set between the member 3a and the rear member 3b. And by filling a heat insulating material, a heat insulating material adhere | attaches and the front side member 3a, the rear side member 3b, and the light-guide plate 24 are fixed firmly. In particular, since the light guide plate 24 is inclined and long and is formed in a flat plate shape, the heat guide material adheres to the light guide plate 24 in a wide area because the surface area of the light guide plate 24 is large. It is firmly fixed to.

  In the above example, the light emitting diode 23a of the illumination 23 uses a white diode that can easily see stored items such as food and drink. However, the illumination 23 provided on the upper front of the heat insulating container 2 is replaced with a colored light emitting diode. The illumination cover 23b made of a transparent resin member covering the outline of the illumination 23 may be colored, and in this way, colored light is transmitted to the light guide plate 24 so that the surface of the front door 3 is transmitted. The front end 24b of the light guide plate 24 that is arranged is colored and turned on, so that the light and darkness of the lighting is clear from turning off, and the refrigerator 1 is turned on even when the room is bright. There is an effect that can be confirmed with.

  In addition, as a color when the colored light emitting diode 23a is used, it is preferable to use the blue light emitting diode 23a. In the case of the refrigerator 1 used in a hospital room or the like, the storage case 9 is illuminated in blue and white. Can be felt clean, and the light on the front side 24b of the light guide plate 24 arranged on the surface of the front door 3 is lit in blue and has a sense of security that is gentle on the eyes. It can be confirmed at a glance that the power is on, and it is not too bright even at night and the like, and it is difficult to disturb human sleep. Further, instead of using the blue light emitting diode 23a, the light from the light emitting diode 23a that is colored blue and transmitted through the illumination cover 23b of the transparent resin member that covers the outline of the illumination 23 is made blue. Similarly, the inside of the storage case 9 can be felt clean by illuminating the inside of the storage case 9 in a similar manner, and the front side end 24b of the light guide plate 24 arranged on the surface of the front door 3 can be seen in blue. A light with a gentle and secure feeling can be seen at a glance that the refrigerator 1 is turned on even when the room is bright, and it is not too bright even at night, etc. The effect that it is suitable for the use in is obtained.

  Further, in the above example, the front side end 24b of the light guide plate 24 is disposed in the front handle hole 3d on the front surface of the front door 3, and the front handle hole 3d can be formed wide vertically, and the front side end 24b is formed. Although the front side end 24b is easy to see from above according to the inclined surface of θ3 in FIG. 6, the top and bottom width of the front handle hole 3d is slightly narrowed as shown in FIG. The front end 24b may be exposed on the front surface of the front door 3 below the front handle hole 3d.

  In the above example, the front side end 24b is a flat example having no irregularities. However, the front side end 24b has a textured surface so that the light from the light emitting diode 23a is blurred on the front side end 24b.
