Description

[Detailed Description of the Invention] The present invention relates to a food sales vehicle used for mobile display and sales of fresh or frozen foods.

Traditionally, mobile sales of foods that require refrigerated storage include
A vehicle such as a small truck whose loading platform is open to the atmosphere is used, and a refrigeration system is mounted on the vehicle. However, in the conventional sales vehicle, the refrigerating case of the refrigerating device is installed on the cargo platform without a cover, and the refrigerating case is exposed to the outside air. Therefore, the food in the refrigerated case may be exposed to direct sunlight, leading to a decrease in the cooling effect, and shoppers cannot be protected from direct sunlight or wind and rain.

In order to eliminate such drawbacks, it is possible to utilize a cab-over type vehicle, such as an automobile, which has a closed space through which people can enter and exit, and to arrange the refrigerated cases in the closed space, that is, the luggage compartment of the vehicle. Conceivable. However, in this case, every time the refrigerated case is opened, the odor emitted from the food stored in the case leaks into the cargo compartment, and as a result, the cargo compartment into which shoppers enter is filled with odor. That will happen. This odor reduces the desire to purchase. Therefore, when the refrigerating case is placed in the closed space described above, forced ventilation of the space is an essential condition.

The present invention contemplates forced ventilation of a closed space in which a refrigerated case is placed without using special forced ventilation means.

The present invention focuses on the fact that the condenser of a refrigeration system mounted on a vehicle is generally an air-cooled type. It is characterized by its use in forced ventilation.

The features of the invention will become clearer from the following description of the illustrated embodiment.

The vehicle 10 according to the present invention is a so-called cab-over type automobile that includes a box-shaped vehicle body 12 and running wheels 14, as shown in FIGS. 1 and 2. Inside the vehicle body 12, a closed space 16 is provided.
(See Figure 3) is specified. Also, car body 1
The upper portion of the periphery of the vehicle 2 is provided with a number of glass windows 18 similar to those in conventional cab-over vehicles. Further, in the front portion of one side of the vehicle body 12, an entrance 20 and an opening/closing door 22 are provided to allow people to enter and exit the space 16.

Referring to FIG. 3, the space 16 is divided by a partition wall 24 into a driver's cab 26 at the front of the vehicle and an exhibition and sales room 28 behind the driver's cab.
Although not shown, various operating devices such as a steering wheel, an accelerator, and a brake for controlling the running of the vehicle 10 are arranged in the driver's cab 26 .

In the illustrated example, the entrance/exit 20 opens to an exhibition/sales room 28 . Access to the driver's cab 26 is possible through an entrance 30 provided in the wall 24. The wall 24 can be made unnecessary. Moreover, both chambers 26 and 28 can be completely shut off by the wall 24 without providing an entrance/exit 30 therein. In this case, an entrance and a door for entering and exiting the driver's cab 26 are provided in the vehicle body 12 independently of the entrance 20 and the door 22.

The vehicle 10 includes a large number of refrigerated cases 32 for storing foods such as frozen foods or fresh foods.
A refrigeration system equipped with an air-cooled condenser 34 for removing heat from the cooling medium to be supplied to each refrigeration case 32 is mounted on the tower.

The refrigerated case 32 is installed on the floor on both sides of the exhibition and sales room 28 in order to secure a passage 36 extending in the front and rear direction of the vehicle 10 in the center of the exhibition and sales room 28, and the condenser 34 is installed on the floor at the center of the exhibition and sales room 28. room 2
4 is installed on the floor at the rear end. The exhibition and sales room 28 may be provided with accessory equipment such as a fresh water tank 38 and a cash register table 40 extending from the room 28 through the wall 24 to the operator's cab 26 depending on the space of the room.

Each refrigerating case 32 incorporates a conventionally well-known evaporator for cooling medium, although not shown, and the refrigerant vapor generated from the evaporator is generated by the engine, which is the driving source of the vehicle 10, although not shown. is introduced into a conventionally well known compressor which is operated by
The cooling medium compressed by the compressor is sent to the condenser 34 and returns to the evaporator of each refrigerating case 32 after removing heat therefrom. Due to the circulation of the cooling medium described above, the food in each refrigerating case 32 is cooled and preserved.

The condenser 34 includes a well-known heat dissipation grid 42 into which the cooling medium from the compressor is introduced;
A fan 44 is provided to generate an air flow passing through the heat dissipation grid. In the illustrated example, fan 4
4 are provided in pairs on one side of the heat dissipation grid 42, and each fan 44 of the condenser 34 is connected to the vehicle body 1.
It is arranged at the rearmost part of the exhibition and sales room 28 so as to face each opening 46 provided in a pair at the rear of the exhibition sales room 28.

A cylindrical hood 48 is provided around each fan 44, surrounding the fan and having one end open to each corresponding opening 46. Both fans 44 are
They are driven and rotated in the same direction by the engine as a driving source or by another driving source independent of the engine. The rotation of this fan 44 causes the second
As indicated at 50 in the figure, an airflow is created through the heat dissipation grid 42 towards the openings 46.

This air stream 50 is discharged to the outside of the vehicle through the openings 46 after effectively removing heat from the cooling medium to be sent to the evaporator of each refrigeration case 32 via the heat dissipation grid 42.

Therefore, the fan 44 of the condenser 34 promotes the action of removing heat from the cooling medium, and
It acts to forcefully ventilate the exhibition and sales room 28.

The number of the fans 44 and openings 46 can be increased or decreased as necessary. Furthermore, the direction of rotation of the fan 44 can be reversed so that the direction of the airflow is opposite to that described above. However, when the air flow 50 is in the opposite direction, the air drawn through the openings 46 is generally at a high temperature, so that the air flow is less effective at removing heat from the cooling medium, and the heat dissipation grid The air, which has become even hotter by passing through 42, is discharged toward the front of the exhibition and sales room 28. Therefore, in order to cause the opening 46 to function as an air outlet, the air flow passes through the fan 44 through the opening 4.
It is preferable to operate it so that it flows out toward the direction 6.

Although the hood 48 can be made unnecessary,
It is desirable to use the hood 48 to ensure that the air flow generated by the operation of the fan 44 passes through the heat dissipation grid 42, thereby increasing the cooling effect of the refrigeration device.

Further, the condenser 34 can be installed at a desired location in the exhibition and sales room 28, but as described above, the condenser 34 is installed at a position separated from the entrance/exit 22 that is opened and closed by people entering and exiting. It is advantageous to ventilate the exhibition and sales room 28 as a whole.

According to the present invention, as described above, a closed space of a vehicle in which a refrigerating case of a refrigeration device is arranged can be forcedly ventilated without using a special ventilation means only for forced ventilation.

Therefore, the closed space can be forcedly ventilated without complicating the configuration of the vehicle, and the odor emitted from the refrigerated case into the closed space every time the refrigerated case is opened and closed is removed to the outside of the vehicle. It can be discharged early. As a result, shoppers entering the closed space will not feel uncomfortable due to the odor, and the odor will not discourage them from purchasing.
