Description

[Technical field]

[0001] The present invention relates to an automobile with an office function, and more particularly to an automobile with an office function capable of controlling air conditioning inside the vehicle compartment. [Background technology]

[0002] Today, most offices are located in office buildings, which are real estate, and many office workers work in their offices. This means that they commute long distances and spend long, unproductive hours. The inventor considered converting the office function from an office building, which is real property, to an automobile, which is movable property. He thought that this could be achieved by using an automobile, which has a spacious interior, and equipping it with office equipment such as a multifunction printer or PC, and office furniture such as desks and chairs that can be used for small meetings.

[0003] However, the interior of an automobile is prone to become very hot, and in order to improve the work efficiency of those who carry out office work inside the automobile, it is necessary to cool or heat the interior of the automobile to keep the temperature inside the automobile at an appropriate level. To achieve this, it may seem like it would be possible to use the car's air conditioner, but the engine must be running when using the car air conditioner, which can lead to problems such as increased exhaust gas emissions at the parking area and noise pollution. One solution to this problem is to install a known room air conditioner in the vehicle cabin and run it on a battery, but this has the problem that the air conditioner cannot be operated for long periods of time because it consumes a lot of power.

[0004] Conventional technology (Patent Document 1) that can reduce the operating load of an air conditioner includes an air conditioner that promotes indoor air convection using a radiant heat exchanger and suppresses the cooling and heating load through the radiant heat effect. However, while this air conditioning system has been proposed for indoor use in homes as well as in large facilities such as gymnasiums and auditoriums, its use in the passenger compartment of an automobile has not yet been considered.

[0005] [Patent Document 1] JP 2015-25627 A Summary of the Invention [Problem to be solved by the invention]

[0006] SUMMARY OF THE PRESENT INVETION The present invention has been made in view of the above circumstances, and has as its object to provide an automobile with an office function, which is capable of operating an air conditioner inside the automobile for a long period of time on battery power. [Means for solving the problem]

[0007] The automobile with an office function of the first invention is an automobile with an office function equipped with office equipment and office furniture in the passenger compartment of the automobile, and is equipped with an air conditioning device for heating and cooling the passenger compartment, The air conditioning system comprises an air conditioner including an indoor unit and an outdoor unit, and a radiant heat exchanger that passes the refrigerant used by the air conditioner through a heating element to radiate and absorb radiant heat, the indoor unit and the radiant heat exchanger being mounted inside the passenger compartment of the automobile, and the outdoor unit being mounted on the outside of the body of the automobile. The second invention is a vehicle with office functions, which is characterized in that, in the first invention, the indoor unit is attached to the upper part at the rear of the passenger compartment, the radiant heat exchanger is positioned below the indoor unit at the rear of the passenger compartment, the indoor unit's air outlet is positioned facing the front of the passenger compartment, and the radiant heat action direction of the radiant heat exchanger is facing the front of the passenger compartment. The automobile with office functions of the third invention is the same as the automobile of the first invention, and is characterized in that the outdoor unit is suspended from a body frame, which is a structural strength member of the automobile, by means of a suspension bracket. Effect of the Invention

[0008] According to the first invention, the automobile has an office function, so it can be used as an office building. Moreover, the radiant heat exchanger can promote the convection of air inside the vehicle, so the air conditioner can be operated less frequently, which reduces battery consumption. Furthermore, the air conditioner's outdoor unit is installed on the outside of the vehicle, so the heat emitted is not released outside the vehicle, which does not reduce the cooling effect inside the vehicle. According to the second invention, the indoor unit and the radiant heat exchanger are disposed at the rear of the vehicle cabin, so that the cool / hot air and radiant heat flow and propagate forward through the center of the vehicle body, enabling the vehicle cabin to be cooled or heated in a short period of time. According to the third invention, the outdoor unit is suspended from the body frame, which is a structural strength member, so that the outdoor unit can be held stably. While the indoor unit and radiant heat exchanger are placed inside the vehicle cabin, the overall center of gravity of the vehicle can be lowered, ensuring the driving stability of the vehicle.

[Diagram 5] FIG. 2 is an explanatory diagram of the schematic configuration of an air conditioning device A. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Next, an embodiment of the present invention will be described with reference to the drawings. In this specification, references to front and rear refer to the front and rear of the vehicle, and references to left and right refer to left and right when looking forward from within the vehicle body.

[0011] (Car with office function) The automobile with an office function according to the present invention has an office space OS equipped with office equipment and furniture within the passenger compartment of the automobile C, and an example of this will be described with reference to Figs. The illustrated automobile C is a station wagon with a total length of about 4 to 5 m, or a bus generally called a microbus with a total length of 6 to 8 m. Note that a medium-sized bus with a total length of about 9 m or a large bus with a total length of about 12 m may also be used. The body structure of the automobile C is a known structure in which the cabin and engine are placed on a body frame 10, which is a structural strength member, and the wheels are suspended below via a suspension device. Note that any body structure other than the structure illustrated may be used.

[0012] In the front of the cabin of the microbus-type vehicle C, there is a driver's seat 11 and a passenger seat 12, and the space behind them is used as an office space OS. A battery 13 is installed behind the passenger seat 12, and this battery 13 is capable of storing electricity generated by a solar panel 14 installed on the ceiling of the car C. The electricity stored in this battery 13 is used to drive the air conditioning device A, which will be described later. There are no particular restrictions on where the battery 13 can be placed, and the passenger seat 12 may be removed and the battery 13 may be installed there.

[0013] The office space OS in the vehicle cabin is equipped with various office equipment and office furniture for working and / or meetings. To enter and exit the office space OS, a sliding door 16 and the subsequent step 17 on the side of the vehicle body can be used. 1 shows, as examples of office equipment, a personal computer monitor 21 (the personal computer itself is placed under a desk 31, which will be described later), a multifunction device 22 with printing / faxing functions, a monitor 23, and a projector 24. These are arranged in this order from the front to the rear in the office space OS, but this is an example and the order is not limited to this. Furthermore, the office equipment is not limited to these, and any type of office equipment can be used.

[0014] A desk 31 with the personal computer monitor 21 placed on it is placed in the front part of the office space OS, and office chairs 32 are placed on both the front and back of the desk 31. A sanitary unit 33 is placed in the center of the office space OS, and is equipped with a toilet, shower, lockers, etc. Opposite the sanitary unit 33 is a kitchen unit 34, which is equipped with cooking utensils such as a sink and a range.

[0015] A meeting table 35 is placed in the rear part of the office space OS, with benches 36, 36 on either side of it. The projector 24 is placed on top of the meeting table 35. A curtain 37 separates the rear part, which serves as the meeting space, from the center part. Projection by the projector 24 can be achieved by lowering a white roll curtain or the like in front of the monitor 23 or the curtain 37, and these means are optional.

[0016] As shown in Fig. 4, the indoor unit 1 and the radiant heat exchanger 4 are disposed at the rear of the vehicle interior, and appropriate furniture is disposed around them. For example, a bench 36 is placed on the left and right sides of the floor in the vehicle interior, and shelves 38 are placed on the left and right sides of the ceiling. The above layout example is just one example. If car C is to function as an office, it may contain various devices and equipment, and their layout may be arbitrary.

[0017] (Air conditioning equipment) The air conditioner installed in the automobile with office function of the present invention is a known device, for example, as described in Patent No. 5544580. Since the present invention is characterized by the arrangement inside the automobile of the air conditioner and radiant heat exchanger that constitute the air conditioner, the configuration and function of the air conditioner itself will only be roughly described.

[0018] The air conditioner A shown in Fig. 5 is made up of an indoor unit 1 (shown by thin dots) and an outdoor unit 2 (shown only in outline), which constitute an air conditioner, and a radiant heat exchanger 4 (shown by thick lines, etc.). The indoor unit 1 and the outdoor unit 2 are connected by a gas pipe 5 and a liquid pipe 6, and perform the refrigeration function of the air conditioner. The radiant heat exchanger 4 is connected by a gas branch pipe 7 and a gas branch pipe 8 that branch off from the gas pipe 5, and is incorporated into the refrigeration cycle of the air conditioner. A drain pipe 9 is also connected to the radiant heat exchanger 4. Note that, although a number of opening and closing valves that control the flow direction and flow rate of the refrigerant are attached to each of the pipes 5 to 8, illustration and explanation of these are omitted.

[0019] An air conditioner consisting of an indoor unit 1 and an outdoor unit 2 is a known device with a cooling and heating function. The indoor unit 1 has an indoor heat exchanger that functions as a condenser or evaporator, and is equipped with a fan that blows out hot and cold air. 1o is an outlet for the hot and cold air. The outdoor unit 2 has an outdoor heat exchanger that functions as an evaporator or a condenser, and a compressor, and further has an exhaust port 2o for discharging air that has undergone heat exchange.

[0020] The radiation type heat exchanger 4 is equipped with a heating element 45 (indicated by thin dots) through which multiple refrigerants pass and a straightening plate (reference number omitted) that straightens the flow of radiant heat, and is fixed by upper, lower, left and right frames 41, 42, 43, 44 (indicated by thick dots). The heating element 45 is connected to the gas branch pipes 7 and 8 via upper and lower headers (not shown). In the radiant heat exchanger 4, the cold and hot heat radiated from the heating element 45 can be used in addition to air conditioning by the air conditioner. This allows air conditioning to start up quickly and improves air convection, so the air volume of the air conditioner can be reduced, reducing the unpleasant draft feeling for the human body and improving comfort. In addition, the air conditioner can be operated for a long time on battery power because the operating frequency of the air conditioner can be reduced to reduce battery consumption. In the illustrated embodiment, the heating element 45 is arranged vertically, but it may also be arranged horizontally.

[0021] (Air conditioning unit placement) In the present invention, the indoor unit 1 and the radiant heat exchanger 4 are installed inside the passenger compartment of an automobile. More specifically, as shown in Figures 2 and 3, the indoor unit 1 is attached to the upper part at the rear of the vehicle interior, and the radiant heat exchanger 4 is disposed below the indoor unit 1 at the rear of the vehicle interior. Also, as shown in Figure 4, the air outlet 1o of the indoor unit 1 is disposed facing the front of the vehicle interior, and the radiant heat emission direction of the radiant heat exchanger 4 faces the front of the vehicle interior.

[0022] As described above, since the indoor unit 1 and the radiant heat exchanger 4 are disposed at the rear of the vehicle interior, the cold / hot air blown out by the indoor unit 1 flows forward through the center of the vehicle body as shown by the arrow y1, as shown in FIG. 3. In addition, the radiant heat generated by the radiant heat exchanger 4 is radiated and absorbed toward the front of the vehicle body as shown by the arrow y2. Therefore, the radiant heat y2 is combined with the cold / hot air y1 blown out by the indoor unit 1 to cool or heat the vehicle interior in a short time. In this way, the air convection is improved, so the air volume of the air conditioner can be suppressed, and the unpleasant draft feeling for the human body can be reduced. Note that natural convection y3 occurs from the upper part of the radiant heat exchanger 4 during heating, and natural convection y4 occurs from the lower part during cooling.

[0023] In the present invention, the outdoor unit 2 is attached to the outside of the body of the automobile. There is no particular restriction on the attachment location as long as it is on the outside of the body, and it may be on the outside of the front or rear of the body, or on the upper or lower side of the body. In the embodiment shown in Fig. 2 and Fig. 5, the outdoor unit 2 is suspended from the body frame 10, which is a structural strength member of the automobile, by using a suspension bracket 15. This suspension position may be in the vicinity of the suspension position of the spare tire, which is the lower rear part of the body, and the outdoor unit 2 may be suspended adjacent to the spare tire, or, if legally possible, by removing the spare tire.

[0024] In this way, because the air conditioner's outdoor unit 2 is mounted outside the vehicle body, the heat it emits is not released outside the vehicle body, reducing the cooling effect inside the vehicle. Also, because the outdoor unit 2 is suspended from the vehicle body frame 10, which is a structural strength member, the outdoor unit 2 can be held stably, and while the indoor unit 1 and radiant heat exchanger 4 are placed inside the vehicle, the overall center of gravity of the vehicle can be lowered, ensuring the running stability of the automobile. [Industrial Applicability]

[0025] According to the present invention, a car can function as an office, and can therefore serve as a substitute for an office building. The car with office functions of the present invention can also contribute to a company's business continuity plan (BCP). The automobile with office functions of the present invention is not limited to a specific industry and can be used in a variety of industrial fields. [Explanation of symbols]
