BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifying device for a refrigerated vehicle for transporting fresh foods such as vegetables, fruits, fish, meat and the like without reducing its freshness, and in particular, runs on land such as trucks and trailers. It relates to a freezer car.

[0002]

2. Description of the Related Art Generally, in order to transport fresh food such as vegetables, fruits, fish, meat and the like without lowering its freshness, as disclosed in Japanese Utility Model Publication No. 62-25651, an upper part of a front wall of a body of a freezing vehicle is disclosed. An evaporator that communicates with the interior of the vehicle body is protruded from the evaporator, and an evaporator of a refrigerator is stored in the interior of the evaporator. Fresh food was cooled, but depending on the fresh food, it may be necessary to supply a larger amount of cold air than usual and force it to circulate.

[0003]

In such a case, the inside of the vehicle body is dried and the humidity is reduced, which results in a decrease in the quality of fresh food. Conventionally, the humidifying device in this case includes a main unit that humidifies the air sucked by the FAN by vibrating water with ultrasonic waves in accordance with an instruction from a humidity adjusting device (sensor switch), and a main unit including the main unit. Since the water tank and the pump are separately installed, the water in the water tank, the pump, and the pipe cannot be completely drained. Since the pump operates only when the humidity control device of the humidifying device is in a humidified state, the remaining water freezes in winter and cold regions, and is susceptible to damage.

[0004]

According to the present invention, an evaporator house communicating with the interior of a vehicle body is protruded above a front wall of a vehicle body of a refrigerating car, and an evaporator of a refrigerator and a main body of a humidifying device are provided inside the evaporator house. The condenser of the refrigerator and the water tank of the humidifier are mounted under the floor of the body of the refrigerator car, and the pump and the drain valve of the humidifier are mounted on the outer surface of the water tank in advance. The water tank and the main body of the humidifier are connected by two pipes.
Connected and the pump is independent of the humidifier body.
The above-mentioned problem is solved by a configuration in which the humidifying water is circulated by operating it .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described below. FIG. 1 shows an entire perspective view of a freezer truck indicated by a chain line with a refrigerator and a humidifier according to the present invention attached thereto, and FIG. FIG. 3 shows a partially cutaway front view in which a pump and a drain valve are mounted, FIG. 3 shows a partially cutout left side view of FIG. 2, and FIG. 4 shows electric wiring of a humidifier.

In the refrigerating vehicle shown in this embodiment, an EVA house 12 communicating with the inside of the vehicle body is protruded above the front wall of the vehicle body 10,
An evaporator 14 of a refrigerator and a main body 16 of a humidifier are housed inside the evaporator house 12, and a body 10 of the refrigerator car is
The condenser 18 of the refrigerator and the water tank 20 of the humidifier are installed under the floor of the case.
The pump 24 is housed in the case 22 in advance so that the rotation axis is vertical and the bottom is lower than the bottom of the water tank 20.

The bottom of the pump 24 and the water tank 20
Is connected by a pipe 28 through a drain valve 26 at a position lower than the bottom of the pump 24,
The drain valve 26 is opened and closed by operating the lever 30. 29 is a pipe for sending water to the main body 16 of the humidifier.

The mounting member 3 is provided on the upper surface of the water tank 22.
2 and 32 are fixed, and are mounted under the floor of the body 10 of the refrigerator car through the mounting members 32 and 32,
4, an inlet 36 and an air vent 38 are provided.
A drain valve 26 is also provided at the bottom of 2.

The electric wiring of the humidifier shown in this embodiment is shown in FIG.
As shown in the figure, the switch for the humidifier in the cab 40 is
When it is set to N, the pump 24 operates continuously irrespective of the humidity adjusting device (sensor switch) 42 to send the water in the water tank 22 to the main body 16 of the humidifying device through the pipe 29 and circulate the water to the water tank 22 through the return pipe 46. . On the other hand, when the humidity adjusting device (sensor switch) 42 is turned on, the main body portion (ultrasonic vibration device) 16 of the humidifier and the humidifier FA
By operating N44, the inside of the vehicle body 10 of the refrigerating car is in a humidified state.

If the condenser 18 of the refrigerator is mounted near the pipes 29 and 46 as shown by the dashed line in FIG.
The water inside 6 is warmed, which also prevents freezing.

[0011]

[Effects of the Invention] Since the present invention is configured as described above, the following effects can be obtained.

Since the water tank, the pump of the humidifier, and the drain valve are fixed and connected by piping, the piping connecting them is very short, little water is collected, and the water drains from the drain valve. Water tank and humidifier
Is connected with two pipes, and the pump is
It operates independently of the humidifier body to circulate humidified water.
Since it is configured so as to be left, damage due to freezing of water can be prevented.

Since the pump of the humidifier and the drain valve are previously mounted on the outer surface of the water tank and connected by piping, the space occupied by these is reduced, and the work of attaching other accessories is facilitated. It has also become easier to attach and detach the body of the frozen car under the floor.

If the condenser of the refrigerator is mounted near the pipe, the water inside the pipe is warmed by the heat radiation of the condenser, thereby also preventing freezing.

Since the pump is housed in a case,
Well protected.
