Abstract

(57) [Summary] (Correction) [Purpose] To provide a freshness preservation device for a refrigeration vehicle that enables easy maintenance and replacement of the evaporator and filter of the refrigerator without removing the bulkhead. An air intake port is formed by opening the lower portion of a bulkhead that is erected from the inner surface of the front wall 16 of the vehicle body 14 with a ventilation gap, and the inside of the vehicle body 14 is formed outside the upper portion of the front wall 16. An evaporator house is provided so as to communicate with each other through an air intake port and a ventilation gap, and a cool air outlet of an evaporator 32 is attached to a ceiling inside the evaporator house so as to open inside the vehicle body 14, and an ethylene adsorption filter is provided inside the evaporator house. At the same time, the bulkhead can open and close the portion that shuts off the inside of the evaporator house and the inside of the vehicle body 14. If a humidifier is attached to the upper surface of the partition plate 48, the inside of the vehicle body 14 can be humidified, and the flat plate above the bulkhead can be opened and closed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a freshness preservation device for a refrigeration vehicle that transports fresh food such as vegetables and fruits while maintaining its freshness.

[0002]

[Prior Art]

 Generally, a refrigerator is mounted on a vehicle body to transport fresh food such as vegetables and fruits while maintaining its freshness, and cool air is blown from the evaporator of the refrigerator to the inside of the vehicle body. It cools the loaded fresh foods and releases aging harmful substances such as ethylene, which causes ripening and aging of the fresh foods, especially in vegetables and fruits, so it is a filter for absorbing this ethylene. Was provided.

[0003]

[Problems to be solved by the device]

 In the cold air circulation structure of a normal refrigeration vehicle, a bulkhead is erected from the inside of the front wall of the vehicle body of the refrigeration vehicle with a gap for ventilation, and the lower part of the bulkhead is opened to form an air intake port. An outermost upper part of the front wall is provided with an evaporator house which communicates with the inside of the vehicle body through the air intake port and the ventilation gap, and a cool air blower of a refrigerator evaporator is installed on a ceiling inside the evaporator house. The outlet is installed so as to open inside the vehicle body, and a filter for absorbing the ethylene is provided inside the air inlet, while an evaporator and an ethylene absorption filter of the refrigerator are used. Maintenance and replacement are required every time, but since the evaporator is installed inside the upper part of the bulkhead and the ethylene absorption filter is installed inside the lower part of the bulkhead, it is necessary to perform maintenance and replacement. Was very troublesome because the bulkhead had to be removed.

[0004]

[Means for Solving the Problems]

 According to the present invention, a bulkhead is erected from the inner surface of the front wall of a vehicle body with a gap for ventilation, and the lower portion of the bulkhead is opened to form an air intake port. An evaporator house that communicates with the inside of the vehicle body through the air intake port and the ventilation gap is projected, and the cool air outlet of the evaporator of the refrigerator opens inside the vehicle body on the ceiling inside the evaporator house. Thus, the above problem is solved by providing the ethylene adsorption filter inside the evaporator house and opening and closing the part where the bulkhead blocks the inside of the evaporator house from the inside of the vehicle body.

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an internal cross-sectional view of a front part and an evaporator house of the refrigeration vehicle of FIG. 2, and FIG. 2 is a side view of the refrigeration vehicle of the present embodiment. 3 is a sectional view taken along the line AA of FIG. 1, FIG. 4 is a sectional view taken along the line BB of FIG. 1, FIG. 5 is a detailed view of a portion C shown in FIG. Shows the details of the portion D in the arrow of FIG. 1, FIG. 7 shows the details of the portion E of the arrow in FIG. 6, and FIG. 8 shows the FF sectional view of FIG.

As shown in FIGS. 1 and 2, a refrigerating vehicle 10 according to this embodiment has a vehicle body 14 mounted on a chassis of a cab 12, and the vehicle body 14 includes a front wall portion 16 and a ceiling portion 18. The floor 20 and the left and right side walls 22, 22 are boxes for transportation, and an evacuation house 24 communicating with the inside of the vehicle body 12 is provided on the outside of the upper part of the front wall. Is a box body composed of a ceiling portion 26, a front end wall portion 28, and a lower inclined portion 30, and is mounted on the ceiling portion 26 so that a cool air outlet 34 of an evaporator 32 of a refrigerator opens inside the vehicle body 14. However, the compressor 36 of the refrigerator is attached to the lower portion of the floor portion 20 of the vehicle body 14.

As shown in FIGS. 1, 3 and 4, the inner surface of the front wall portion 16 of the vehicle body 12 has a Z-shaped cross section and is spaced from the upper surface of the floor portion 20 by a distance of H to blow the cold air. A plurality of columns 38, 38 extending upward to the vicinity of the outlet 34 are erected at a predetermined gap and a flat plate 40 serving as a bulkhead is adhered to the gap between the adjacent columns 38 and 38 to cool air. There is no duct, a portion of the floor 20 at an interval h from the upper surface is a cold air inlet 42, and an opening / closing plate is provided at a portion of the plurality of columns 38, 38 ... As shown in FIG. 1, the upper edge of the flat plate 42 is pivotally attached to the upper portions of the plurality of columns 38, 38 through hinges 44, and the lower edge of the flat plate 42 is shown in FIG. Is removably fixed to the plurality of columns 38, ..

As shown in FIG. 1 and FIG. 7, the inside of the evaporator house 24 is divided into upper and lower parts by a partition plate 48 having an L-shaped cross section except the part occupied by the evaporator 32, and the partition plate 48 is An inclined support member 50 having a Z-shaped cross section is fixed between the lower surface and the lower inclined portion 30 of the evaporation house 24.

As shown in FIGS. 7 and 8, an appropriate number of hooks 54, 54, ... Are arranged in a row on the lower surface of the partition plate 48 through the bending members 52, and these hooks 54.5
A filter 56 containing an adsorbent that absorbs aging harmful substances such as ethylene released from perishable products is suspended in 4 .., and the lower end of the filter 56 is a nylon fastener 58 fixed to the upper surface of the inclined portion 30. It is detachably fastened by a wire mesh 60 and is protected by a wire mesh 60.

[0010]

【effect】

 With the above configuration, the cold air sucked from the cold air inlet 42 flows upward in the duct of the cold air formed by the gap between the adjacent columns 38 and 38, and when passing through the filter 56, fresh products are discharged. The aging harmful substance such as ethylene is absorbed, flows into the inside of the evaporator house 24, and is blown out from the cold air blowout port 34 of the evaporator 32 of the refrigerator, but the blown out cool air is guided to the inclined cold air guide plate 64. Since it is burnt and completely flows into the duct 62, it smoothly flows through the inside of the vehicle body 14 and the cold air is sufficiently distributed to the cargo.

If the humidifier 62 is attached to the upper surface of the partition plate 48, the inside of the vehicle body 14 can be humidified and the flat plate 42 above the bulkhead can be opened and closed. Maintenance and inspection of the evaporator 32 of the inside refrigerator and replacement of the filter 56 can be easily performed.
