  In this Embodiment 1, the small refrigerator 1 using one thermomodule 18 (refer FIG. 6 etc.) using the quiet and compact size Peltier device as an example of the storage 1 is shown. As shown in FIG. 1 and the like, the refrigerator 1 forms an outer shell by a heat insulating container 2 whose front surface is open and a front door 3 that closes the front surface of the heat insulating container 2. Further, as shown in FIG. 5 and the like, the heat insulating container 2 includes an inner box 4 and an outer box 5, a foam heat insulating material (not shown) injected so as to be interposed between the inner box 4 and the outer box 5, and the like. The heat insulation container 2 insulates the inside and outside of the refrigerator 1 from heat.

  Next, the configuration of the front door 3 will be described. The front door 3 is also filled with a heat insulating material (not shown) to insulate the front surface of the refrigerator 1. As shown in FIG. 4 and the like, the front ends of the left frame 6 and the right frame 7 which are formed long in the back and are supported so as to be drawn back and forth with respect to the heat insulating container 2 are fixed on the left and right sides of the back surface of the front door 3. In addition, the rear end portion of the left frame 6 and the right frame 7 is connected by a stay 8, and the storage portion formed in a frame shape when viewed from above formed by the front door 3, the left and right frames 6, 7 and the stay 8. In addition, a food storage case (storage case) 10 formed of a resin member for storing stored items such as food and drink 9 is detachably fitted and fixed. Thus, the box-shaped food storage case 10 which is fixed to the rear of the front door 3 and whose upper surface is opened is moved back and forth from the heat insulating container 2 by moving the front door 3 back and forth from the heat insulating container 2. In this way, the food storage case 10 is pulled forward from the heat insulating container 2 so that stored items such as food and drink 9 can be easily taken in and out from above without any obstacles. And since the food / drink 9 is easy to put in and take out in this way, it is suitable for a small refrigerator used in a hospital room or the like, which is often used by elderly people, for example.

  Moreover, since the front door 3 is pulled out only in the front and rear, there is no need for a space for the door to be rotated 90 degrees or more and opened left or right so that the door does not get in the way like a conventional small refrigerator. The installation space can be narrowed, and it is easy to install in a room with little space such as a hotel or hospital room. In particular, in hotels and the like, it is often installed in a state where only the front door 3 portion of the refrigerator 1 can be seen by being pushed into a wall or furniture to improve the appearance, and the drawer type by the front door 3 and the food storage case 10 is often used. With this configuration, the space for installing the left and right refrigerators 1 of the refrigerator 1 can be narrowed, and a product that can be easily installed in a hotel room can be obtained.

  Next, the configuration of the inner box 4 will be described. As shown in FIGS. 4 and 12, the inner box 4 includes a heat transfer plate 11 made of a metal member such as aluminum having a U-shaped side cross-section that integrally forms the upper and lower surfaces and the rear surface. The left side plate 12 and the right side plate 13 are formed of a resin member that closes the left and right sides of the heat transfer plate 11 and are formed in a box shape with the front surface opened. In this way, the heat transfer plate 11 is formed of a metal member because it transmits cold heat from a thermo module 18 using a Peltier element, which will be described later, which serves as a cooling means, and the food 9 and the like from the top, bottom, and back surfaces. In addition, by forming the left side plate 12 and the right side plate 13 with resin members, the left and right rail portions 12a and 13a with which the left and right frames 6 and 7 are put in and out are recessed by resin molding. This is because it is easy to make, and as an example of the resin material of the left and right side plates 12 and 13, if it is molded with a sticky member such as polypropylene, a material that is difficult to crack and is easy to mold is obtained.

  In addition, by forming the left and right side plates 12 and 13 with resin members, the shape of the heat transfer plate 11 becomes a simple U-shaped three-surface shape with only the upper and lower surfaces and the back surface, and up to the left and right side walls as in the past. Since it is not necessary to perform deep drawing so that the five surfaces are integrally formed, the metal plate can be easily formed, and the inner box 4 can be formed at low cost. In addition, rollers 12b and 13b for guiding the left and right frames 6 and 7 are provided in front of the left and right rail portions 12a and 13a, respectively. Further, a roller 7a for moving the right rail portion 13a is provided on the rear side of the right frame 7, and a roller (not shown) for moving the left rail portion 12a is also provided on the rear side of the left frame 6. It has been.

  Next, the configuration of the outer box 5 will be described. As shown in FIG. 4 and the like, the outer box 5 has an upper surface composed of a lower three-surface member 14 having a concave shape when viewed from the front and formed integrally by bending three surfaces of the left and right side surfaces and the lower surface, and a resin member forming the upper surface The member 15 and the back member 16 made of a resin member covering the back surface form five surfaces. In addition, a frame-shaped frame 17 is provided on the front surface of the outer box 5 to improve the appearance and prevent foam insulation (not shown) from leaking from the gap between the front side of the outer box 5 and the inner box 4. Yes. Further, as shown in FIGS. 6 and 11, a thermo module 18 that cools the heat transfer plate 11 is fixed to the back member 16. The thermo module 18 is composed of a Peltier element, and in the rear wall of the heat insulating container 2, a storage hole passes through the outer box 5 and a heat insulating material (not shown), leaving a metal plate constituting the heat transfer plate 11 of the inner box 4. The thermo module 18 is disposed in the storage hole. Further, an aluminum alloy heat transfer block 19 having good thermal conductivity is interposed between the thermo module 18 and the heat transfer plate 11 of the inner box 4, and the heat transfer block 19 is inserted into the heat transfer plate 11 of the inner box 4. The heat transfer surface portion of the thermo module 18 and the heat transfer plate 11 of the inner box 4 are joined via a heat transfer block 19 so that heat can be transferred. The heat transfer block 19 is integrally fixed to the heat insulating container 2 by injecting a heat insulating material. In addition, the thermo module 18 is fixed to the heat transfer block 19 by screws or the like from the rear side.

  Further, as shown in FIG. 6 and the like, a heat sink 20 is provided which is thermally conductively joined to the heat source side heat exchange surface portion of the thermo module 18, and the heat sink 20 is configured to exchange heat by circulating outside air in the vertical direction. In addition, a large number of aluminum fins are arranged in the vertical direction. Further, the entire back surface of the heat insulating container 2 is covered so as to cover the heat sink 20, and electrical parts (not shown) and the like are stored outside the rear wall of the heat insulating container 2, and a ventilation path for cooling the heat sink 20 is formed. A back cover 22 is provided. The back cover 22 is formed in a substantially box shape with the front surface open, and the bottom surface of the back cover 22 is inclined upward as it goes rearward, and a suction port 22a for sucking outside air from the bottom surface is opened. Further, the upper surface of the back cover 22 is inclined downward as it goes rearward, and an exhaust port 22b is formed in the upper surface portion.

  Also, a blower fan 23 is provided inside the exhaust port 22b, and the outside air sucked from the suction port 22a below the refrigerator 1 passes through the heat sink 20 by the rotation of the blower fan 23 disposed at the upper part of the refrigerator 1 and is heated. It is exchanged and discharged from the upper exhaust port 22b. Further, since the suction port 22a on the lower surface of the back cover 22 is inclined upward as it goes rearward, the distance between the floor surface on which the refrigerator 1 is installed and the suction port 22a is widened as shown by the dimension H in FIG. The air path resistance for sucking outside air is small, dust is prevented from being sucked from the floor, and clogging of the filter 26 and the like which will be described later is prevented and maintenance such as cleaning of the filter 26 can be facilitated. In addition, since the blower fan 23 is arranged at the upper part of the refrigerator 1, the distance from the blower fan 23 to the suction port 22a is long, so that the wind speed of the intake air sucked from the suction port 22a can be prevented from increasing, and therefore the suction port 22a. There is also an effect of preventing the inhalation of dust from.

  With such a configuration, in the refrigerator 1 of this embodiment, the heat transfer block 19 is cooled by the Peltier element thermo-module 18, and the upper and lower surfaces and the back surface of the inner box 4 are integrated from the heat transfer block 19. Cold heat is transmitted to the formed heat transfer plate 11, the food and drink 9 in the food storage case 10 stored in the heat insulating container 2 is cooled by the cooled heat transfer plate 11, and the temperature in the heat insulating container 2 is 3 ° C. to 7 ° C. Refrigerated to the extent. Further, the heat sink 20 side of the Peltier element is configured such that the heat sink 20 is cooled by the outside air sucked from the suction port 22a by the blower fan 23, and the heat of the Peltier element (thermo module) 18 is radiated. The air that has passed through the heat sink 20 is discharged from the exhaust port 22b.

  Next, the heat transfer plate 11 formed of a metal member such as an aluminum alloy that constitutes the inner box 4 is configured by three surfaces of the upper and lower surfaces and the rear surface, and the left and right surfaces are configured by the left and right side plates 12 and 13 of the resin member. The effect of this will be described in more detail. Since the rear surface of the heat transfer plate 11 is a surface to which heat from the thermo module 18 is first transmitted, the inside of the refrigerator 1 can be cooled particularly effectively, and the cold heat is transmitted from the upper side to the lower side. Since the upper surface of the inner box 4 is composed of the heat transfer plate 11, the inside of the refrigerator can be effectively cooled from above. Moreover, the lower surface of the inner box 4 is composed of the heat transfer plate 11 and is also cooled from below, so that the inside 1 of the refrigerator can be sufficiently cooled from the upper and lower sides and the rear side, and the left and right side plates 12 and 13 are made of resin. It can be formed of a member.

  Further, by integrally forming the lower surface of the heat transfer plate 11 from the back surface, the dew adhering to the heat transfer plate 11 by the cooling is smoothly transferred from the back surface to the lower surface, and the drain outlet 24 on the lower surface of the heat transfer plate 11 is formed. There is also an effect that can be easily collected and drained. In addition, by configuring the lower surface of the inner box 4 with the heat transfer plate 11, for example, when the application direction of the power source of the thermo module 18 is switched to have a function like a refrigerator as well as a refrigerator. Since the heat is transmitted from the lower side to the upper side, it is possible to obtain heat that can effectively keep the interior from the lower surface portion of the heat transfer plate 11.

  Further, by forming the left and right side plates 12 and 13 of the inner box 4 separately from the heat transfer plate 11 with resin members, not only the rail portions 12a and 13a can be easily molded, but also in this embodiment, FIG. As shown in the G dimension of the cross-sectional view, the rail portions 12 a and 13 a can be formed further to the rear than the back surface of the heat transfer plate 11 of the inner box 4. Thereby, since the front and rear moving distances of the left and right frames 6 and 7 fixed to the front door 3 can be increased, the distance between the food storage case 10 and the back surface of the heat transfer plate 11 as shown in the side sectional view of FIG. The storage space before and after the food storage case 10 can be made narrower, the distance for pulling out the food storage case 10 forward can be increased, and the storage capacity of the food and drink 9 can be sufficiently widened even in the small refrigerator 1, Moreover, there exists an effect by which what can take in and out of food easily is obtained.

  In addition, the front door 3 that covers the entire front surface of the refrigerator 1 is provided with a single food storage case 10, and the configuration of the drawer-type refrigerator 1 that is put in and out of the front and rear is a refrigerator with a large storage capacity for storing a container 9 such as food. However, it is suitable for small refrigerators with a food storage capacity of 15 liters to 45 liters used in hotels, hospital rooms, etc., especially if the storage capacity is in the range of 20 liters to 30 liters. It is optimal as a refrigerator used in hospital rooms that refrigerate beverages. Moreover, since it was set as the structure refrigerated with the thermo module 18 using a Peltier device as a cooling means, a refrigerator becomes large with a compressor like the refrigerator using a refrigerating cycle, or the sound of a compressor operation | movement and a refrigerant | coolant circulating. Therefore, it is possible to obtain a refrigerator that is very quiet and has a low noise level that prevents people from sleeping, and that the refrigerator 1 that is optimal as a refrigerator 1 in a hotel or hospital room can be obtained.

  Next, a configuration for storing a 2-liter plastic bottle 9a as an example of stored items such as food and drink 9 will be described. The PET bottle 9a with a capacity of 2 liters is a general one and has an outer height of about 310 mm. The thick part of its body is cylindrical and has a diameter of about 90 mm, and a rectangular shape of about 90 mm × 100 mm. There are many sizes of small refrigerators that are used in hotels and hospital rooms, especially those that cannot be stowed upside down, even if they are standing upright. Purchase a lot of 500ml plastic bottles. There was a problem that the purchase cost was higher than purchasing a 2 liter size such as storing (for example, while selling 2 liter size PET bottles for about 200 yen when selling cheap, 500 The size of milliliters is about 100 yen, so if you buy 2 liters, you can purchase 4 liters for about 400 yen, about twice the size of 2 liters. Use is required become very expensive.). Further, when the plastic bottle 9a is tilted sideways and stored, the beverage may leak out from the lid portion 9b, or in the case of carbonated beverage, the carbonated beverage may blow out due to the impact when it is taken out and stood. In this embodiment, as shown in FIGS. 8 and 9, a 2 liter-sized plastic bottle 9a can be stored in a state of being inclined forward.

  By doing in this way, there is no dimension of about 310 mm or more which can store the height of the 2 liter-sized PET bottle 9a in the vertical height, depth, and left and right width of the food storage portion in the inner box 4 of the refrigerator 1. Even if there is a height and depth that can store a 2 liter size PET bottle 9a diagonally forward, the 2 liter size PET bottle 9a can be stored and the storage capacity is a small size of about 20-30 liters. The refrigerator 1 which can fully accommodate the 2 liter size PET bottle 9a was obtained. Further, by storing the 2 liter-sized plastic bottle 9a in a state where the upper side is inclined to the near side from the standing state, the vertical height of the refrigerator 1 can be lowered, and in the event of an earthquake, etc. A refrigerator that is difficult to move and toppling over is obtained, and is suitable for a refrigerator installed in a hotel or hospital room. In particular, in the case where the food storage case 10 in which the stored items 9 are easy to be taken in and out is a drawer type, it is necessary to provide a slight gap between the food storage case 10 and the lower surface of the inner box 4 so as to be easily pulled out. The height of the refrigerator 1 is required by the gap, but since the height of the refrigerator 1 can be lowered by tilting and storing the plastic bottle 9a, the configuration is suitable for the configuration of the drawer-type storage case. Yes.

  Further, when the front door 3 is moved back and forth with the upper surface portion of the front door 3 and the like, and the 2 liter-sized plastic bottle 9a is taken in and out, the thin and easy to hold lid 9b side is the front door 3 side. Since it comes to the near side, there is an effect that it is easy to hold the plastic bottle 9a and it is easy to take in and out. In addition, as a reason that the 2 liter size PET bottle 9a can be tilted and stored, the 2 liter size PET bottle 9a falls forward and can be stored as long as the front door is rotated left and right as in the conventional case. However, according to this embodiment, the box-shaped food storage case 10 that is pulled out together with the front door 3 and the front door 3 is required. Since the storage portion is configured, the 2 liter size PET bottle 9a can be easily stored without falling forward.

  In addition, as the angle at which the upper part of the 2 liter-sized plastic bottle 9a is inclined forward, as shown by the F angle in FIG. 9, a food storage capacity of 20 to 30 liters when the inclination is about 30 to 40 degrees from the horizontal plane. It was suitable for a small refrigerator of the horizontally long (type wider than height) type.

  Moreover, as a structure which supports the upper part of the 2 liter size plastic bottle 9a, it is good also as a structure supported by the front side part of the food storage case 10, but in this embodiment, it is 2 liters further on the back surface of the front door 3. When the plastic bottle 9a having a size is tilted and stored, a recess 3a is formed as a storage portion of the lid portion 9b in which a portion where the lid portion 9b portion is located is recessed forward according to the shape of the lid portion 9b, and 2 liters The size and height of the refrigerator can be reduced by the amount that the lid portion 9b of the 2 liter size PET bottle 9a is located in front of the front surface of the heat insulating container 2 while preventing the size of the PET bottle 9a from moving back and forth. The small refrigerator 1 can accommodate a 2-liter plastic bottle 9a.

  Next, the configuration of the drain pan 25 formed of a resin member and the filter 26 formed of a resin member will be described. As shown in FIGS. 6 and 7, the drain outlet 24 is provided at the bottom of the heat insulating container 2. Then, the drain water adhering to the inner surface of the inner box 4 is guided to a dish-shaped drain pan 25 disposed below the heat insulating container 2. As shown in FIG. 10 etc., the foot 27 is arrange | positioned in a total of four places on the bottom face of the heat insulation container 2, front and rear, and right and left, and it arrange | positions so that a level | step difference part may face each. As shown in FIGS. 14 and 15, the drain pan 25 has a substantially T-shaped horizontal plane, the front width is made larger than the rear width, and the drain capacity can be increased. The drain pan 25 is configured so that the left and right sides of the drain pan 25 are guided between the step portions of the left and right foot 27. As a result, the drain pan 25 is attached so that its rear portion is slidably inserted between the stepped portion of the foot 27 and the bottom surface of the heat-insulating container 2 so as to be able to move back and forth.

  Further, a filter 26 is provided at the rear part of the drain pan 25 so as to be pivotally supported by the rear part of the drain pan 25 and cover the suction port 22a opened on the bottom surface of the rear part of the refrigerator 1. When the air flows through the suction port 22a, the heat sink 20 It is possible to remove dust and the like mixed in the air flowing into the air. In the filter 26, the shafts 26a and 26b provided at the left and right front portions use the elasticity of the resin member to the bearings 25a and 25b formed at the left and right of the rear portion of the drain pan 25 corresponding to the shafts 26a and 26b. By being pushed in, the rear side of the filter 26 is rotatably fitted upward as shown by a two-dot chain line in FIG. 15, and is simply supported so that the filter 26 does not come off from the drain pan 25. The filter 26 is supported by the drain pan 25 so as not to rotate downward from a horizontal state.

  6 and 7, when the drain pan 25 is inserted into the lower surface of the refrigerator 1, the filter 26 attached to the rear of the drain pan 25 passes under the drain drain port 24 to form the suction port 22a. The filter 26 is guided along the upward inclination of the lower surface of the back cover 22 and rotated by the shafts 26a and 26b, and the rear of the filter 26 is disposed in the suction port 22a. 1 can be set in the suction port 22a at the rear part. Further, when removing the filter 26, the filter 26 can be pulled out and removed by pulling the drain pan 25 forward of the refrigerator 1. For this reason, even when the refrigerator 1 is installed in a wall or furniture and maintenance can be performed only from the front door 3 side, the filter 26 can be easily attached and detached from the front of the refrigerator 1 for easy cleaning. is there. Further, since the filter 26 is inclined upward as it goes rearward along the suction port 22a, the distance between the filter 26 and the floor surface on which the refrigerator 1 is installed is wide (H dimension in FIG. 7), so that it accumulates on the floor surface. It is difficult to suck the dust and the like, and there is an effect that the period during which the filter 26 needs to be cleaned can be lengthened.

  Next, lighting of the refrigerator 1 will be described. As shown in FIG. 10 and FIGS. 16 to 18, an illumination 28 of a light emitting diode (light emitting part) 28 a is provided on the front upper part of the center of the left and right of the heat insulating container 2. It is easy to use the refrigerator so that the stored items can be seen. The light emitting diode 28a is connected to the printed wiring board (wiring board) 29 by soldering or the like in a substantially vertical state, and the front side of the wiring board 29 is inclined upward as shown in FIG.
