[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a constant temperature and high humidity cabinet equipped with a cold air circulation duct.

[0002]

[Prior art]

 In recent years, in the preservation of foods, from the viewpoint of maintaining the freshness of foods, various preservation techniques have been proposed, such as refrigeration preservation, frozen preservation, partial preservation, and constant temperature and high humidity preservation.

The above-mentioned conventional constant temperature and high humidity chamber will be described below with reference to the drawings. FIG. 2 shows a conventional constant temperature and high humidity chamber. In FIG. 2, reference numeral 1 is a main body cabinet made of a heat-insulating box whose front surface is open, 2 is a door having a heat-insulating body, a compressor 3 and a condenser 4 are provided above the ceiling of the main body cabinet 1, and the ceiling of the main body cabinet 1 is provided. A cooler 5 is provided in the section, a drain pan 5a is provided below the cooler 5, a condenser motor 6 and a condenser fan 7 are provided in the condenser 4, and a cooler motor 8 and a cooler fan 9 are provided in the cooler. I am.

A drainage pipe 12 for draining water in the refrigerator is formed by covering the cooler 5 with a top surface 10a, a back surface 10b, both side surfaces 10c, a bottom surface 10d, and an inner box 10 which also serves as a duct 11 which is sequentially connected. Is provided on the bottom surface 10d of the inner box 10. The back surface 1a of the main body cabinet 1 is provided with a recess 1b for embedding a drain hose 13 for draining the defrost water of the cooler 5.

The operation of the constant temperature and high humidity chamber configured as described above will be described below with reference to FIG.

First, cold air generated by a cooling device sequentially connected to the compressor 3, the condenser 4, and the cooler 5 passes through the space between the inner box 10 which also serves as the duct 11 and the main body cabinet 1 to the top surface 10. a, the back surface 10b, the bottom surface 10d, both side surfaces 10c, and the ceiling surface 10a again are sent by the fan 9 for a cooler, and the inside of the refrigerator is cooled by the wall surface of the cooled inner box 10. Therefore, the air in the refrigerator does not pass through the cooler 4 and is not dehumidified. As a result, the inside of the refrigerator is kept at high humidity.

Further, water droplets accumulated in the refrigerator are drained by a drainage pipe 12 provided in the inner box 10, and defrost acid of the cooler 5 is drained by a drainage hose 13 provided in a recess 1b on the back surface 1a of the main body cabinet. It

[0008]

[Problems to be solved by the device]

 However, in the above-mentioned conventional configuration, the drain hose 13 is passed through the recess 1b of the back surface 1a of the main body cabinet, so that the mounting becomes complicated. Further, since the heat insulating material of the concave portion 1b of the back surface 1a of the main body cabinet is thin, there is a drawback that sweating easily occurs.

The present invention is intended to solve the above-mentioned conventional problems, and provides a constant temperature and high humidity chamber that allows defrost water of a cooler to flow along the back side of the main body cabinet in the duct to prevent sweating on the back side of the main body cabinet. The purpose is to provide.

[0010]

[Means for Solving the Problems]

 In order to achieve this purpose, the constant temperature and high humidity chamber of the present invention is provided with a drain plate at the lower part of the cooler, which has a square hole for flowing defrost water along the back side of the cabinet in the duct. .

Further, the bottom of the main body cabinet is provided with a drainage port for draining water droplets in the refrigerator and the cooler, and an external drainage pipe.

Further, the top surface on the rear side of the inner box is provided with an opening for allowing water drops to flow into the refrigerator.

[0013]

[Action]

 The constant temperature and high humidity chamber of the present invention has the above-mentioned configuration, so that the defrost water of the cooler flows along the back side of the main body cabinet in the duct, and thus the perspiration of the back side of the main body cabinet can be prevented.

Further, since the water droplets in the refrigerator and the defrost water of the cooler are drained at one place, the installation can be simplified.

Further, it is possible to keep high humidity all the time.

【Example】

 Hereinafter, a first embodiment of a constant temperature and high humidity chamber according to the present invention will be described with reference to the drawings. It should be noted that the same components as those of the related art will be denoted by the same reference numerals and detailed description thereof will be omitted.

FIG. 1 is a sectional view of a constant temperature and high humidity chamber according to a first embodiment of the present invention. In FIG. 1, reference numeral 14 denotes a drain plate, which is provided with a square hole 14a and is inclined toward the cabinet rear surface 1a side in the duct 11.
