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 air-conditioning the interior of the automobile. [Background technology]

[0002] Today, offices are often 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 office functions from an office building, which is real estate, to a vehicle, which is movable property. He thought that this could be achieved by using a vehicle with a spacious interior and installing office equipment such as a multifunction printer or PC, as well as office furniture such as desks and chairs that can be used for small meetings.

[0003] However, the temperature inside an automobile is prone to become high, and in order to improve the work efficiency of those who handle office work inside the automobile, it is necessary to cool or heat the interior of the automobile to maintain the temperature inside the automobile at an appropriate level. To achieve this, it may seem like the best thing to do is to use the car's air conditioner, but this requires the engine to be running, which can lead to problems such as increased exhaust gas emissions and noise pollution at the parking spot. One solution to this problem is to install a conventional room air conditioner in the vehicle cabin and run it on a battery. However, this method has the problem that the air conditioner cannot be operated for long periods of time due to the large amount of power consumed by the air conditioner.

[0004] A conventional technique (Patent Document 1) that can reduce the operating load of an air conditioner is an air conditioner that promotes indoor air convection using a radiant heat exchanger and reduces the heating and cooling 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 application to automobile cabins has not yet been considered.

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

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

[0011] (Car with office functions) The automobile with office functions according to the present invention has an office space OS equipped with office equipment and furniture inside the cabin of the automobile C, and an example thereof will be described with reference to FIGS. The illustrated automobile C is a 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 automobile C is a well-known structure in which the passenger compartment, engine, etc. are mounted on a body frame 10, which is a structural strength member, and the wheels are suspended below via a suspension system. Note that any body structure other than the structure shown in the figure may be used.

[0012] The microbus-type vehicle C has a driver's seat 11 and a passenger seat 12 at the front of the cabin, 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 installed there.

[0013] The office space OS inside the vehicle 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 on the side of the vehicle body and the subsequent step 17 can be used. In Figure 1, examples of office equipment include a computer monitor 21 (the computer itself is placed under a desk 31, which will be described later), a multifunction printer 22 with printing / faxing functions, a monitor 23, and a projector 24. These are arranged in this order from the front to the back of 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 PC monitor 21 placed on it is placed in the front part of the office space OS, and office chairs 32 are placed on both sides in front and behind it. A sanitary unit 33 is located 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 a sink, a range, and other cooking utensils.

[0015] A meeting table 35 is placed in the rear 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 portion, which serves as the meeting space, from the center portion. The projection from the projector 24 can be achieved by lowering a white roller blind or the like in front of the monitor 23 or the curtain 37; these means are optional.

[0016] As shown in Figure 4, the indoor unit 1 and the radiant heat exchanger 4 are located at the rear of the vehicle cabin, with appropriate furniture arranged around them. For example, benches 36 are placed on the left and right sides of the floor in the vehicle cabin, and shelves 38 are placed on the left and right sides of the ceiling. The above example of layout is just one example, and if car C is to function as an office, it can include various devices and equipment, and their layout can be arbitrary.

[0017] (Air conditioning equipment) The air conditioning system installed in the automobile with office functions of the present invention is a known system, for example, as described in Patent Publication No. 5544580. Since the present invention is characterized by the arrangement of the air conditioner and radiant heat exchanger that make up the air conditioning system within the automobile, only a schematic explanation of the structure and function of the air conditioning system itself will be given.

[0018] The air conditioner A shown in Figure 5 comprises an indoor unit 1 (shown by thin dots) and an outdoor unit 2 (shown only in outline), which constitute the 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, which perform the refrigeration function of the air conditioner. The radiant heat exchanger 4 is connected by gas branch pipes 7 and 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 each of the pipes 5 to 8 is fitted with a number of on-off valves that control the flow direction and flow rate of the refrigerant, but these are not shown or described here.

[0019] An air conditioner consisting of an indoor unit 1 and an outdoor unit 2 is a well-known device with heating and cooling functions. 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 cold and warm air. 1o is an outlet for the cold and warm 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 outlet 2o for discharging air that has undergone heat exchange.

[0020] The radiation heat exchanger 4 is equipped with a heating element 45 (shown by thin dots) through which multiple refrigerants pass and a rectifying plate (reference number omitted) that rectifies the flow of radiant heat, and is fixed by upper, lower, left, and right frames 41, 42, 43, and 44 (shown 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 the air conditioning to start up quickly and improves air convection, making it possible to reduce the airflow volume of the air conditioner, reducing the unpleasant draft feeling felt by the human body and improving comfort. In addition, the operating frequency of the air conditioner can be reduced, reducing battery consumption, allowing the air conditioner to operate for long periods of time on battery power. 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 the 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 release direction of the radiant heat exchanger 4 faces the front of the vehicle interior.

[0022] As described above, the indoor unit 1 and radiant heat exchanger 4 are positioned at the rear of the vehicle cabin. As shown in Figure 3, the cool / hot air blown out by the indoor unit 1 flows forward through the center of the vehicle, as indicated by arrow y1. In addition, the radiant heat emitted by the radiant heat exchanger 4 is radiated and absorbed toward the front of the vehicle, as indicated by arrow y2. This allows the radiant heat y2 to combine with the cool / hot air y1 blown out by the indoor unit 1, thereby cooling or heating the vehicle cabin in a short time. This improves air convection, reducing the airflow volume of the air conditioner and reducing the unpleasant draft feeling experienced by humans. Natural convection y3 occurs from the upper portion of the radiant heat exchanger 4 during heating, and natural convection y4 occurs from the lower portion during cooling.

[0023] In the present invention, the outdoor unit 2 is mounted on the outside of the vehicle body. There are no particular limitations on the mounting location as long as it is on the outside of the vehicle body, and it may be on the outside of the front or rear of the vehicle body, or on the upper or lower side of the vehicle body. In the embodiment shown in Figures 2 and 5, the outdoor unit 2 is suspended from the body frame 10, which is a structural strength member of the vehicle, using a suspension bracket 15. This suspension position may be near the suspension position of the spare tire, which is on the lower rear side of the vehicle body, and the outdoor unit 2 may be suspended adjacent to the spare tire, or, if legally permitted, with the spare tire removed.

[0024] In this way, the air conditioner's outdoor unit 2 is mounted outside the vehicle body, so 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 vehicle's driving stability. [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]
