Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air circulation structure of a refrigerating vehicle equipped with a humidifying device for transporting fresh food such as vegetables, fruits, fish and meats without deteriorating the freshness thereof, and particularly for transporting the food at a higher freshness than before. The present invention relates to an air circulation structure of a refrigerating vehicle such as a truck or a trailer equipped with a humidifying device, which runs on land.

[0002]

[Prior art]

 Generally, in order to transport fresh foods such as vegetables, fruits, fish and meats without deteriorating their freshness, the evaporator of the refrigerator is mounted on the upper part of the front wall of the body of the refrigerating vehicle. In order to keep the freshness of fresh foods by cooling them with the evaporator and forcibly refluxing the inside of the car body with a fan, it is necessary to transport them at a low temperature according to the type of fresh foods. Is.

For example, in the case of fruits, the temperature range is such that cold damage does not occur, and in the case of fish meat, which causes a change in taste when frozen, the temperature range is such that it does not freeze. However, since there is no problem with fish meat, a low temperature condition corresponding to it is required, and depending on the fresh food, it may be necessary to supply a larger amount of cold air than usual and forcefully circulate it. As a result, the inside of the car body dries and the humidity drops, which in turn adversely affects the quality of fresh food. Therefore, a humidifier was installed in addition to the conventional refrigerator.

[0004]

[Problems to be solved by the device]

 As shown in Japanese Patent Application No. 4-25982, the main body of the humidifier of a normal refrigeration vehicle is provided with the blower part of the refrigerator in the upper part of the front part of the cargo room of the heat insulating structure, and the air circulation structure is provided for the load. It is formed by extending a duct panel with a gap from the ceiling surface of the room, and a damper is openably and closably provided between the air outlet of the air blower and the air flow passage, and water is generated by ultrasonic waves. Is vibrated and ejected in a mist form to the blower part of the refrigerator.The remaining mist and the mist accumulated when the damper is closed when the air blow is stopped are changed to water again and the duct panel There was a case in which the water flowed upward, and the water did not flow into the gutters provided on both sides of the duct panel, thereby contaminating the luggage in the luggage compartment.

An object of the present invention is to prevent water accumulated on the duct panel from flowing smoothly into the gutters provided at the lower portions of both sides to prevent the luggage in the luggage compartment from being contaminated.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the main body of the humidifier and the air blower of the refrigerator are provided at the upper part of the front part of the heat-insulated luggage compartment, and the duct panel is provided with a gap from the ceiling surface of the luggage compartment. An air flow passage is formed by stretching, and a damper is openably and closably provided between the air outlet of the air blower and the air flow passage. The damper is opened when the air is blown, and when the air blow is stopped by its own weight. It is configured to close automatically, and a drain pan having a rising flange at the side edge or rear edge is laid on the upper surface of the duct panel, and gutters into which water from the drain pan flows are provided at the lower left and right sides of the duct panel. There is provided an air circulation structure for a refrigerating vehicle equipped with a humidifying device, characterized in that a return pipe for returning water accumulated at the bottom of the trough to the humidifying device is provided.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an inner detailed view of a portion A in FIG. 4 showing an air circulation structure of a refrigerating vehicle equipped with a humidifier according to the present invention, and FIG. FIG. 3 is a partial perspective view of an air circulation structure to which the present invention is applied, and FIG. 4 is a side view of a refrigeration vehicle to which the present invention is applied.

The air circulation structure of a refrigerating vehicle according to the present embodiment is provided with a main body 12 of a humidifier and a blower 16 of a refrigerator 14 at the upper part of the front of a heat-insulated luggage compartment 10. An air flow passage 24 is formed by extending the duct panel 20 through a suspension member 22 with a gap from the ceiling surface 18, and the air flow passage 24 is formed between the air blow port of the blower unit 16 and the air flow passage 24. A damper 26 is provided so as to be openable and closable, the damper 26 is opened when air is blown, and is automatically closed by its own weight when the air blow is stopped. On the upper surface of the duct panel 20, rising flanges 28, 28 are formed on the side edges. The drain pan 30 having the above structure is laid, and is constructed so as to be joined to the drain pan 30 when the damper 26 is closed. The rising flanges 28, 28 prevent water on the drain pan 30 from going out, so Is the luggage contaminated? Can be prevented.

Gutters 21 and 21 are provided on the lower left and right sides of the duct panel 20, and drainage holes 23 and 23 correspond to the drain pan 30 and the duct panel 20 so that water flows into the gutters 21 and 21, respectively. The water that is transparently provided at the position and collected in the gutters 21 and 21 is returned to the main body 12 of the humidifier through a return pipe 32.

[0010]

【effect】

 As described above, in this plan, a drain pan having rising flanges at the side edge or the rear edge is laid on the upper surface of the duct panel of the air flow passage, and water from the drain pan flows into the lower part on both the left and right sides of the duct panel. Since there is a gutter and a return pipe that returns the water accumulated at the bottom of the trough to the humidifying device, the excess mist generated during humidification and the mist accumulated when the damper is closed when the air blow is stopped, It will not turn into water again and flow over the duct panel to contaminate luggage in the luggage compartment.
