As shown in Patent Documents 1 to 3, when the ultraviolet light emitting lamp is embedded in the wall surface of the storage room, the ultraviolet light from the lamp can be irradiated toward the storage room, so that the storage room can float or be stored. It can sterilize various germs adhering to the wall surface of the chamber. However, in the configurations of Patent Documents 1 to 3, it is unavoidable that dead zones where ultraviolet light does not reach are formed, such as the surface of the cooling fan in the cooling unit and the surface of the cooler. No bactericidal action against germs adhering to the surface of vessels, etc. can be obtained. In addition, compared to refrigerators that are operated under sub-zero conditions where it is difficult for germs to grow, a thawing chamber that thaws frozen products such as frozen foods has a high operating temperature and is prone to breed germs. For this reason, a more strict sterilization action is required in the thawing warehouse, and it is desirable that the dead zone where the ultraviolet light does not reach is as small as possible.

SUMMARY OF THE INVENTION An object of the present invention is to provide a thawing warehouse which is excellent in sterilization ability and sterilization efficiency by suppressing the formation of dead zones where ultraviolet rays do not reach.

The present invention is directed to a thawing chamber for thawing frozen food in the chamber. The thawing chamber is formed by filling a foam insulating material 15 between an inner box 13 and an outer box 14, and comprises a heat insulating box body 4 having a storage room 3 for storing frozen foods, and a front opening 6 of the storage room 3. A door 7 to be opened and closed, a cooler 65 disposed so as to be in contact with the outer surface of the inner box 13 constituting the heat insulating box body 4 on the side of the foam insulation material 15 to cool the air in the refrigerator, and the air in the refrigerator to be circulated. A blower 23 for blowing air, a heater 26 for heating the air in the refrigerator, and an ultraviolet lamp 24 for emitting ultraviolet light are provided. The inner surface of the inner box 13 on the storage chamber 3 side is a mirror surface. The blower 23, the heater 26, and the ultraviolet lamp 24 are assembled in a blower unit 17 arranged along one of the left and right sides of the storage chamber 3. A storage area R for storing frozen food is set. The ultraviolet lamp 24 is arranged inside a lamp chamber 50 formed inside the blower unit 17 . A partition wall 66 that partitions the lamp chamber 50 has a first opening 57 that allows ultraviolet light emitted from the ultraviolet lamp 24 to irradiate the storage area R, and a second opening 58 that allows ultraviolet light to irradiate the blower 23. , and a third opening 59 for allowing irradiation of ultraviolet light toward the heater 26 .

The partition wall 66 includes a side case 28 that constitutes the blower unit 17 and faces the storage area R, a first partition wall 52 arranged between the blower 23 and the ultraviolet lamp 24, the heater 26 and the ultraviolet lamp 24. and a second partition wall 53 disposed between. A first opening 57 is formed in the side case 28 , a second opening 58 is formed in the first partition wall 52 , and a third opening 59 is formed in the second partition wall 53 .

The lamp chamber 50 is partitioned in four directions by the side case 28 , a first partition wall 52 , a second partition wall 53 and a third partition wall 54 . The third partition wall 54 includes a first reflecting wall 54a for redirecting the ultraviolet light emitted from the ultraviolet lamp 24 toward the second partition wall 53, and a first reflecting wall 54a for redirecting the ultraviolet light toward the side case 28 side. 2 reflective walls 54b are formed.

A photocatalyst C can be placed inside the lamp chamber 50 .

In the defrosting warehouse according to the present invention, the ultraviolet lamp 24 is provided in the blower unit 17, and the partition wall 66 that partitions the lamp chamber 50 of the blower unit 17 is provided with ultraviolet light emitted from the ultraviolet lamp 24 to the storage area R. A first opening 57 allowing irradiation, a second opening 58 allowing irradiation of the blower 23 with ultraviolet light, and a third opening 59 allowing irradiation of the heater 26 with ultraviolet light were formed. According to this, the ultraviolet light emitted from the ultraviolet lamp 24 can be irradiated not only to the storage area R, but also to the blower 23 and the heater 26 in the blower unit 17, so that it can be directed only to the storage area R. The dead zone in which the ultraviolet light does not reach can be made smaller in the storage chamber 3 than in the conventional structure in which the ultraviolet light is irradiated. Therefore, according to the present invention, the entire inside of the refrigerator including the inside of the blower unit 17 can be irradiated with ultraviolet light, so that a defrosting refrigerator having excellent sterilization ability and sterilization efficiency can be obtained. In particular, in the conventional configuration in which the ultraviolet light emitting lamp is arranged on the side wall of the storage chamber facing the cooling unit, it is difficult to irradiate the blower fan and the heater with ultraviolet light. When the ultraviolet lamp 24 is attached to the blower unit 17 together with the blower 23 and the heater 26, the blower 23 and the heater 26 can be reliably irradiated with ultraviolet light. In addition, the inner surface of the inner box 13 constituting the heat insulating box 4 on the side of the storage chamber 3 is mirror-finished, and the cooler 65 is disposed so as to be in contact with the outer surface of the inner box 13 on the foam insulating material 15 side. By eliminating unevenness on the inner surface of the inner box 13 on the side of the storage chamber 3, attenuation of the ultraviolet light when reflected on the inner surface of the inner box 13 is suppressed, and a dead zone is generated in the storage chamber 3. Since it is possible to irradiate the entire inside of the storage room 3 with ultraviolet light while suppressing the contamination, it is possible to obtain a thawing chamber excellent in sterilization ability and sterilization efficiency in this respect as well.

When the first opening 57 is formed in the side case 28 that constitutes the blower unit 17, compared to a configuration in which a separate light guide path is provided for sending the ultraviolet light emitted from the ultraviolet lamp 24 to the storage area R, the configuration is reduced. It is possible to reliably irradiate the storage area R with ultraviolet light while achieving simplification.

The third partition wall 54 constituting the partition wall 66 has a first reflecting wall 54a for redirecting the ultraviolet light emitted from the ultraviolet lamp 24 to the second partition wall 53 side, and the ultraviolet light to the side case 28 side. If the second reflecting wall 54b for changing direction is provided, the ultraviolet light emitted from all directions of the ultraviolet lamp 24 can be directed to the heater 26 or the storage area R. As a result, the output of the ultraviolet light directed toward the heater 26 and the storage area R can be increased, so that the entire inside of the refrigerator can be sterilized more reliably and efficiently.

When the photocatalyst C is placed inside the lamp chamber 50, the photocatalyst C is excited by the ultraviolet light from the ultraviolet lamp 24, and its oxidation-reduction reaction decomposes organic matter and kills germs. Therefore, the ultraviolet light emitted from the ultraviolet lamp 24 can directly kill germs and further improve the sterilization ability.

A heater 26 is arranged between the rear case 27 and the left side 13L of the storage chamber 3 . The heater 26 in this embodiment is a sheath heater, and the heater pipe includes a horizontal portion 61 positioned above the blower 23 and extending in the front-rear direction, and a first vertical portion 62 extending downward from the front and rear ends of the horizontal portion 61. and a second vertical portion 63 that reverses and extends upward from the lower end of the first vertical portion 62 (see FIG. 3). Reference numeral 64 in FIG. 1 denotes a holder for fixing the heater 26 to the rear case 27. As shown in FIG.

1 to 3, reference numeral 65 denotes a cooler, which is an evaporator responsible for cooling the air inside the storage room 3. FIG. The cooler 65 is arranged so as to be in contact with the outer surface of the inner box 13 on the side of the foamed heat insulating material 15 , and cools the inside air through the inner box 13 . More specifically, the cooler 65 is a refrigerant pipe formed in a meandering shape, and is arranged so as to come into contact with the outer surface of the rear surface 13B of the inner box 13 facing the storage area R on the foam insulation 15 side. A cooling device responsible for supplying refrigerant to the cooler 65 is composed of the compressor 9, the condenser 10, the condenser fan 11, and the like.

In the thawing chamber 1 of the present embodiment having the above configuration, when the air blower 23 is turned on and the propeller fan 41 is rotated, the air inside the storage area R is blown through the front guard 47 by the blowing unit. The air is sucked in from the right side surface of 17 and then delivered to the space between the left inner box 13 and the left side surface 13L. The air in the refrigerator sent out from the blower unit 17 flows along the left side 13L, passes between the inner box 13 and the blower unit 17, and passes through the rear surface 13B of the inner box 13, the lower surface 13D, the upper surface, and the heat insulating door 7. , and is fed into the storage area R of the storage chamber 3 . At this time, if the heater 26 is turned on, the internal temperature can be increased. Conversely, when the cooler 65 is turned on, the internal temperature can be lowered. As described above, by turning the heater 26 and the cooler 65 on and off, it is possible to maintain the inside of the refrigerator at a predetermined temperature and perform the thawing process on the stored food.

By pressing a lamp button (not shown), the ultraviolet lamp 24 is turned on to sterilize the entire inside of the refrigerator. Specifically, when the ultraviolet lamp 24 is turned on, ultraviolet light is emitted radially from the irradiation area of the lamp 24 when viewed from the front. Of the ultraviolet rays emitted radially in this way, the ultraviolet rays emitted rightward are irradiated to the storage area R through the first opening 57 . The ultraviolet light emitted downward is applied to the blower 23 through the second opening 58 . The ultraviolet light emitted leftward is applied to the heater 26 through the third opening 59 . The ultraviolet light emitted upward is reflected by the first and second reflecting walls 54a and 54b, respectively, is irradiated to the heater 26 through the third opening 59, and passes through the first opening 57. The storage area R is irradiated with the light through.

As described above, according to the thawing chamber 1 of the present embodiment, not only the storage area R in the storage chamber 3 but also the blower 23 and the heater 26 assembled to the blower unit 17 are irradiated with ultraviolet light. Since sterilization can be performed by irradiating, it is possible to suppress the occurrence of a dead zone where ultraviolet rays do not reach, and to perform sterilization more reliably and efficiently. At this time, since the inner surface of the inner box 13 on the side of the storage chamber 3 is mirror-finished, it is possible to prevent the storage area R from forming a dead zone where ultraviolet rays do not reach, and the storage area R can be sterilized more reliably. It can be carried out.

By disposing the cooler 65 so as to be in contact with the outer surface of the inner box 13 on the foam insulating material 15 side, and by eliminating unevenness on the inner surface of the inner box 13 on the storage chamber 3 side, the dead zone is formed into the storage area R. can be prevented from occurring. By making the inner surface of the inner box 13 on the side of the storage room 3 a mirror surface, it is possible to suppress the attenuation of the ultraviolet light when it is reflected on the inner surface. can be sterilized effectively. A sterilization effect can also be expected by irradiating the back (left side) of the blower unit 17 and the back (left side) of the heater 26 with the ultraviolet light reflected on the left side 13L of the inner box 13 .

Since the first opening 57 is formed in the side case 28 that constitutes the blower unit 17, the configuration is simplified compared to a configuration in which a separate light guide path is provided for sending the ultraviolet light emitted from the ultraviolet lamp 24 to the storage area R. , the storage area R can be reliably irradiated with the ultraviolet light.

The third partition wall 54 constituting the partition wall 66 has a first reflecting wall 54a for redirecting the ultraviolet light emitted from the ultraviolet lamp 24 to the second partition wall 53 side, and the ultraviolet light to the side case 28 side. Since the second reflecting wall 54b for changing the direction is provided, the ultraviolet light emitted from all directions of the ultraviolet lamp 24 is directed to the heater 26 or the storage area R, and is directed to the heater 26 or the storage area R. Since the output of the directed ultraviolet light can be increased, the entire inside of the refrigerator can be sterilized more reliably and efficiently.

Since the photocatalyst C is formed on the entire inner and outer surfaces of the partition plate 51 facing the ultraviolet lamp 24, the ultraviolet light from the ultraviolet lamp 24 can be expected to excite the photocatalyst C, resulting in a sterilizing effect. More specifically, the photocatalyst C that has received ultraviolet light, which is the excitation light, from the ultraviolet lamp 24 decomposes organic matter through oxidation-reduction reactions that occur on its surface. Can be sterilized. Since the photocatalyst C is formed on the entire inner and outer surfaces of the partition plate 51 that partitions the lamp chamber 50 of the ultraviolet lamp 24, the ultraviolet light, which is the excitation light, can be irradiated from a position closely facing the photocatalyst C. Therefore, more light energy can be supplied to the photocatalyst C, and the bactericidal action of the photocatalyst C against various germs can be efficiently exhibited.

FIG. 7 shows another embodiment of the defrosting warehouse according to the present invention. In this thawing chamber 1, the photocatalyst C formed on the entire inner surface of the partition plate 51 is eliminated, and a louver 70 coated with a photocatalyst is installed inside the left wall 53 in the lamp chamber 50. Different from the example. The louver 70 has a large number of blades 71 extending in the vertical direction, and slits 72 are formed between adjacent blades 71 for passing ultraviolet light. A thin film of photocatalyst C is formed on the surface of each blade 71 . Since other points are the same as those of the previous embodiment, the same members are denoted by the same reference numerals, and the description thereof will be omitted.

Also in the thawing chamber 1 according to this another embodiment, when the photocatalyst C formed on the surface of the blade 71 is irradiated with the ultraviolet light, which is the excitation light, the oxidation-reduction reaction occurs on the surface of the photocatalyst C to decompose the organic matter. can do. Therefore, germs adhering to the surface of the blade 71 can be sterilized. Since the photocatalyst C can be placed inside the lamp chamber 50, ultraviolet light, which is the excitation light, can be irradiated from a position facing the photocatalyst C closely. Therefore, more light energy can be supplied to the photocatalyst C, and the bactericidal action of the photocatalyst C against germs is efficiently exhibited.

In the above embodiment, the blower unit 17 is arranged on the left side of the storage chamber 3, but it is also possible to adopt a form in which the blower unit 17 is arranged on the right side of the storage chamber 3, that is, along the right side 13R of the inner box 13. can. In this case, the members arranged in the storage chamber 3 are arranged in opposite directions from those in the above embodiment.
