Description

  The present invention relates to a detachable cooler for keeping the cargo compartment of a cargo compartment integrated vehicle cold.

Conventionally, a driver's cab (cab) and a luggage compartment are provided separately on the chassis, and the luggage compartment is insulated to keep the cargo compartment at a low temperature by using a heat insulation structure. Refrigerated vehicles and refrigerated vehicles that supply cold air are known and used for transporting fresh foods and frozen products.
These cold storage vehicles, refrigerated vehicles, and refrigerated vehicles are excellent in that the inside of the cargo compartment can be kept at a low temperature for a long time. However, since they are generally expensive, there is a need for an inexpensive vehicle with reduced cooling performance.
Therefore, for the so-called dry air that does not have a heat insulation structure or cooling device, the cargo compartment passes through the rear part of the operator's cabin from the air outlet of the operator's cabin air conditioner, once exposed to the outside, and then penetrates the front wall of the cargo compartment A cold insulation device having a duct that reaches the cargo compartment is known (see Patent Documents 1 to 3).
According to these cold insulators, the cargo compartment can be kept cold by introducing the cool air blown from the air conditioner in the cab into the cargo compartment via the duct.
In the present specification, a vehicle in which a driver's cab and a luggage compartment such as a dry car, a cold storage car, a refrigerator car, and a freezer car are separated from each other is referred to as a “cargo compartment separate vehicle”. Other vehicles such as light vans such as 2-box, 1.5-box, and one-box, station wagons, campers, etc. It is expressed as “room-integrated vehicle”.

However, the cold insulator disclosed in the prior art has the following problems.
That is, in a separate vehicle with a cargo compartment to which the above-described cold insulation device is applied, it is common that a window is not provided on the side of the cargo compartment in order to suppress a temperature rise in the cargo compartment due to sunlight irradiation or the like. Therefore, the cold insulation effect can be easily obtained simply by introducing cool air into the cargo compartment from the duct attached to the air outlet of the air conditioner.
However, in a cargo room integrated vehicle, it is necessary to ensure daylighting in the cargo room, and since it is common to provide a window on the side of the cargo room, a duct attached to the air outlet of an air conditioner as in the prior art Therefore, simply introducing cool air into the cargo compartment cannot suppress an increase in temperature in the cargo compartment due to sunlight irradiation or the like, and there is a problem that a sufficient cooling effect cannot be obtained.

In particular, due to the recent increase in environmental awareness, it is recommended to stop the engine when the vehicle is parked or stopped. Even if the engine and air conditioner are stopped and the introduction of cold air into the cargo compartment is temporarily stopped, In a separate cargo compartment type vehicle, since the cargo compartment does not have a window, the cold state in the cargo compartment can be maintained within a certain time.
However, as described above, in the cargo compartment integrated vehicle, a lot of windows are provided on the side surface of the cargo compartment, and the cargo compartment and the cab are spatially connected. As a result of a large amount of sunlight entering through the windows, there is a problem that the temperature in the cargo compartment rises rapidly within a short time after the engine is stopped.
In addition, in a cargo compartment integrated vehicle, cargo such as fresh food that needs to be kept cold is not always loaded into the cargo compartment, but when cargo that does not require cold storage is loaded or the cargo compartment can be used as a rear seat. For this reason, the conventional structure in which the cold insulation device is installed on the vehicle has a problem that it cannot respond flexibly to changes in the use of the luggage compartment.
Furthermore, in a separate cargo compartment type vehicle, it is necessary to make a hole in the driver's cab and the cargo compartment to pass through the duct, which causes troublesome construction work and lowers the vehicle sales price because of modifications. There is also a problem.

  In view of such problems, an object of the present invention is to provide a detachable cooler for a cargo compartment integrated vehicle that can effectively cool the cargo compartment and can be easily detached.

The detachable cooler for a cargo compartment integrated vehicle according to the present invention is used for a cargo compartment integrated vehicle in which a driver's cab and a cargo compartment are integrated, and is simply formed by surrounding the cargo compartment. A cold insulation room, a door that allows a part of the simple cold room to be opened and closed, and a duct having one end connected to the cold air outlet of the cab and the other end opened to the simple cold room, The duct is detachable from the cold air outlet.
Further, the simple cold storage chamber and the duct are formed of a material having a heat shielding property.

Since the present invention provides a simple cold storage room surrounding the cargo compartment, it is possible to effectively suppress a temperature rise due to sunlight irradiation from the windows, etc. for a cargo compartment integrated vehicle having many windows on the side of the cargo compartment. A sufficient cooling effect can be obtained. This cold insulation effect can be maintained while the engine and the air conditioner of the cargo compartment integrated vehicle are stopped and the cold air introduction into the cargo compartment is temporarily stopped.
In addition, since the duct is detachable, when the luggage compartment is used as a rear seat or the like, the simple cold storage compartment and the duct can be removed to respond flexibly to changes in the use of the luggage compartment.
In addition, it is not necessary to make a hole for the duct to pass through the cab and the cargo compartment as in the case of separate vehicles in the cargo compartment, so the construction is easy, and the sale price of the vehicle decreases due to modification Can be prevented.
Moreover, the cold-retaining effect can be further enhanced by forming the simple cold-reserving chamber and the duct with a material having a heat shielding property.

An embodiment of a detachable cooler (hereinafter sometimes simply referred to as “detachable cooler”) for a luggage compartment integrated vehicle of the present invention will be described with reference to the drawings. In this embodiment, a one-box type light van is used as the cargo compartment integrated vehicle.
As shown in FIGS. 1 to 3, the detachable cooler 1 is roughly composed of a simple cool chamber 10, a door 20 and a duct 30.
The simple cold storage chamber 10 is formed by surrounding the interior of the luggage compartment 100. In the present embodiment, the front, rear, left, right, and upper and lower surfaces of the luggage compartment 100 are enclosed in a box shape. In order to prevent the cold air from escaping to the outside, it is preferable to form the simple cold storage chamber 10 in a box shape as in this embodiment, but for example, it is formed with five surfaces on the front, rear, left and right without having a lower surface. Alternatively, in the case where the luggage compartment integrated vehicle has a structure that does not include a door on either of the left and right sides, the simple cold storage chamber 10 is formed without the surface (for example, the right surface) that does not include the door. Also good.
The material of the simple cold storage chamber 10 is preferably heat-insulating. For example, the surface of a cellular sheet made of polyethylene or the like is affixed with a metal foil such as aluminum, or the surface of the polyester fabric is vinyl chloride. Examples thereof include a tent material coated with a synthetic resin such as a resin. Moreover, if the raw material which has heat insulation and heat insulation is used, cold insulation performance can be improved more. Furthermore, it is preferable that the material of the simple cold chamber 10 has flexibility. This is because by providing flexibility, the detachable cooler 1 can be folded or rolled and stored in the luggage compartment 100 when not used.
The simple cold storage chamber 10 is held in a three-dimensional box shape that is detachable from the luggage compartment 100. As the method, for example, the string 11 is attached to the four corners on the upper outer side of the simple cold storage chamber 10, and each string 11 is tied to the protrusions in the luggage compartment 100, or the four corners on the upper outer side of the simple cold storage chamber 10 Attach the ring to the top of the luggage room 100 and place a pipe that extends in the front-rear direction. Examples thereof include a method of magnetizing the metal part in the chamber 100, but are not limited thereto.

The door 20 is provided in order to make it easy to load and unload the baggage into and from the simple cool room 10 by allowing a part of the simple cool room 10 to be freely opened and closed. The door 20 is preferably provided at a position corresponding to the left and right doors (see FIG. 1) and a position corresponding to the rear door (see FIGS. 2 and 3). 2 and 3, the illustration of the rear door is omitted.
As the opening / closing mechanism of the door 20, known means such as a wire fastener (chuck), a point fastener (snap button), a hook, a hook-and-loop fastener, and a magnet may be used.

One end of the duct 30 is a member that is detachably connected to the cold air outlet 102 of the driver's cab 101 of the vehicle, and the other end is a member that is opened into the simple cold room 10.
The duct 30 may be attached to all of the cold air outlets 102 present in the cab 101, or may be attached to only a part thereof. In the present embodiment, a duct 30 is attached to each of the two cold air outlets 102 as shown in FIG. In addition, the ducts 30 attached to the plurality of cold air outlets 102 may be joined together in the middle and connected to the simple cold storage chamber 10 or may be simply connected without joining the plurality of ducts 30. It may be connected in the cold room 10. Of course, it is necessary to arrange the duct 30 at a position that does not hinder driving.
The duct 30 is preferably connected to the upper part of the simple cold chamber 10. FIG. 3 shows a connection port 30a between the duct 30 and the simple cold storage chamber 10. As a result, the cold air moves from the upper side to the lower side in the simple cold chamber 10, so that the entire simple cold chamber 10 can be kept cold at a substantially uniform temperature.
The material constituting the duct 30 preferably has a heat shielding property, and the same material as that of the simple cold storage chamber 10 can be used.
As a method of detachably connecting the duct 30 to the cold air outlet 102, for example, as shown in FIG. A well-known means such as a method of attaching the other fastener to the end of the duct 30 or a line fastener (chuck), a point fastener (snap button), a hook, or a magnet can be used instead of the hook-and-loop fastener.

The present invention is not limited to the configuration shown in the above embodiment, and can be appropriately changed without departing from the gist thereof. For example, by attaching a partition plate to the simple cold storage room 10, the interior is divided into a plurality of compartments, and the luggage that needs to be kept cold at the lowest temperature is loaded into the compartment far from the door, and the cargo that needs to be frequently taken in and out May be loaded into a compartment close to the door.
Further, a door may be provided in a part of the duct 30 so that a part of the cool air can be introduced into the cab 101.
Of course, the detachable cooler 1 of the present invention can also be used as a simple warmer by blowing warm air from the cold air outlet 102.
