Description

[Technical Field]

[0001] The present invention relates to a portable toilet unit for use outdoors, such as at a construction site or building site, and a vehicle equipped with the portable toilet unit. [Background technology]

[0002] Portable toilet units have been available for use outdoors at construction sites, etc. For example, Patent Document 1 below discloses a vehicle with a toilet unit mounted on the loading platform that combines a toilet with an office and rest room. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-205961

[0004] However, in the toilet unit described in Patent Document 1, a passageway is provided between the toilet and the office / rest room to prevent odors from inside the toilet from directly entering the office / rest room, but the presence of this passageway causes the entire toilet unit to become larger and each room, such as the toilet or office / rest room, to become smaller, which creates the problem of reducing the freedom of layout of each of these rooms.

[0005] The present invention has been made to address the above-mentioned problems, and its purpose is to provide a portable toilet unit and a vehicle equipped with a portable toilet unit that allows the entire toilet unit to be made smaller and each room, such as a toilet or an office / break room, to be made larger, while also allowing for greater freedom in the layout of each of these rooms. Summary of the Invention

[0006] In order to achieve the above-mentioned object, the present invention is characterized in that a portable living room housing that forms a living space is provided with a toilet room with a toilet bowl and an adjacent toilet room with a toilet entrance / exit for entering and exiting the toilet room, and the adjacent toilet room is provided with an air blowing device that forcibly blows air toward the toilet entrance / exit.

[0007] According to this, the portable toilet unit is equipped with an air blower that forcibly blows air toward the toilet entrance into the adjacent toilet room adjacent to the toilet room, thereby preventing odors from inside the toilet room from directly entering the adjacent toilet room, allowing the entire portable toilet unit to be made smaller and each room, such as the toilet room or adjacent toilet room, to be made larger, while also increasing the degree of freedom in the layout of each of these rooms.

[0008] Another feature of the present invention is that in the portable toilet unit, the air blower is an air conditioner that outputs cool air or warm air toward the toilet entrance.

[0009] According to this, the portable toilet unit is composed of an air conditioner whose blower outputs cool or warm air toward the toilet entrance, so that the toilet room and the room adjacent to the toilet can be cooled or heated while preventing odors from inside the toilet from directly entering the room adjacent to the toilet.

[0010] Another feature of the present invention is that in the portable toilet unit, the toilet room has a ventilation opening that communicates with the outside of the living room housing.

[0011] According to this, the portable toilet unit has a ventilation opening in the toilet room that connects to the outside of the living room housing, so that odor-containing air from inside the toilet room can be prevented from being expelled outside the living room housing by the air blowing device and flowing toward the room adjacent to the toilet.

[0012] Another feature of the present invention is that in the portable toilet unit, the ventilation opening is provided with an exhaust device that sucks in air from within the toilet room and forcibly expels it to the outside of the living room housing.

[0013] According to this, in the portable toilet unit, the ventilation opening is equipped with an exhaust device that sucks in air from within the toilet room and forcibly discharges it outside the living room housing, so that air containing odors from within the toilet room can be forcibly discharged outside the living room housing.

[0014] Another feature of the present invention is that in the portable toilet unit, the toilet-adjacent room extends longitudinally along the direction of entry and exit of the toilet entrance to form a living space, and is equipped with an opening and closing door for opening and closing the toilet entrance, a main entrance and exit for entering and exiting the toilet-adjacent room from outside the living room housing, and a window that allows the inside of the toilet-adjacent room to be seen from outside along the direction of entry and exit of the toilet entrance.

[0015] According to this, the portable toilet unit has a living space formed by the toilet adjacent room extending long along the direction of the toilet doorway, so that a queue of people waiting to use the toilet can be effectively formed in the toilet adjacent room with the toilet doorway as the base point. Here, the fact that the toilet adjacent room extends long along the direction of the toilet doorway to form a living space means that the length of this living space in the direction of the doorway is longer than the length in the width direction perpendicular to the direction of the doorway.

[0016] In addition, since the portable toilet unit is provided with a door that opens and closes the toilet entrance, it is possible to prevent odor-containing air from inside the toilet room from flowing into the adjacent toilet room, and the amount of air blown into the toilet room by the air blower can be adjusted by the opening degree of the door. Furthermore, since the portable toilet unit is provided with a main entrance in the adjacent toilet room for entering and exiting the adjacent toilet room from outside the living room housing, outside air can be introduced into the adjacent toilet room each time the portable toilet unit enters and exits the adjacent toilet room, thereby reducing odors within the adjacent toilet room. Furthermore, since the portable toilet unit is provided with a window in the adjacent toilet room along the direction of the toilet entrance that allows the interior of the adjacent toilet room to be viewed from outside, it is possible to check the queue of people waiting to use the toilet in the adjacent toilet room, i.e., the degree of congestion of the toilet, from outside.

[0017] Another feature of the present invention is that the portable toilet unit is provided with a main entrance / exit for entering and exiting the living room housing from the outside, and the toilet entrance / exit is located opposite the main entrance / exit.

[0018] According to this, the portable toilet unit has a toilet entrance located opposite the main entrance for entering and exiting the living room housing from the outside, so that the outside air flowing in from the main entrance can be effectively directed toward the toilet room, preventing odors from within the toilet room from flowing toward the room adjacent to the toilet.

[0019] Furthermore, the present invention can be implemented not only as an invention of a portable toilet unit, but also as an invention of a vehicle equipped with a portable toilet unit.

[0020] Specifically, a vehicle equipped with a portable toilet unit may be provided with a portable toilet unit as set forth in any one of claims 1 to 6 and a loading platform on which the portable toilet unit can be placed. As a result, a vehicle equipped with a portable toilet unit can be expected to achieve the same effects as the portable toilet unit described above.

[0021] In this case, in the vehicle equipped with the portable toilet unit, the living room housing may have a window, and the window may have a shutter.

[0022] According to this, since the vehicle equipped with the portable toilet unit has a window with a shutter in the living room casing, it is possible to prevent damage to the window when the vehicle equipped with the portable toilet unit is traveling, and the shutter being closed also indicates to those around that the portable toilet unit cannot be used.

[0023] In addition, in these cases, in the vehicle equipped with the portable toilet unit, the toilet room is located adjacent to the rear of the driver's cab, which is located at the very front of the vehicle equipped with the portable toilet unit in the direction of travel, and the toilet-adjacent room is located rearward of the toilet room in the direction of travel of the vehicle equipped with the portable toilet unit.

[0024] According to this, in a vehicle equipped with a portable toilet unit, the toilet room is located adjacent to the rear of the driver's cab, which is located at the very front of the vehicle in the direction of travel, and the toilet adjacent room is located rearward of the toilet room in the direction of travel of the vehicle.Since the toilet room is located between the driver's cab and the toilet adjacent room, it is possible to prevent the toilet room from being damaged during transportation and leaking waste, etc.

[0025] In these cases, in the vehicle equipped with the portable toilet unit, the roof of the living space housing may be formed so as to rise higher from the front side to the rear side of the vehicle equipped with the portable toilet unit.

[0026] According to this, in a vehicle equipped with a portable toilet unit, the roof of the living room housing is formed higher from the front to the rear of the vehicle, so that the roof is pushed downward by the air flowing from the front of the vehicle onto the roof surface, thereby stabilizing the portable toilet unit on the loading platform and reducing wind pressure resistance when the vehicle equipped with a portable toilet unit is traveling.

[0029] (100 vehicles equipped with portable toilet units) This portable toilet unit-equipped vehicle 100 is a vehicle equipped with a simple-installation toilet that can be installed, moved, or removed primarily outdoors without the need for sewer construction. Portable toilet unit-equipped vehicle 100 is primarily composed of vehicle 101 and portable toilet unit 110.

[0030] Vehicle 101 is a four-wheeled vehicle that can be loaded with portable toilet unit 110 and transported, and can be used with portable toilet unit 110 loaded therein, and is configured by integrally forming a driver's cab 102, with the driver's seat and passenger seat covered by a single roof, and a loading platform 103 on which luggage is placed. In other words, vehicle 101 is a typical truck with no roof or walls and equipped with loading platform 103 that is open to the outside. In this embodiment, vehicle 101 is a flatbed truck (a so-called 2-ton long truck) with a loading capacity of 2.95 t, and loading platform 103 is 4,300 mm long and 1,780 mm wide.

[0031] The portable toilet unit 110 is a simple-installation toilet that can be installed, moved, or removed primarily outdoors without the need for sewer construction. The portable toilet unit 110 is composed of a box-shaped living room housing 111.

[0032] The room housing 111 is a portable building that integrally includes the room spaces of the toilet adjacent room 130 and the toilet room 140. In this embodiment, the room housing 111 is formed in the shape of a rectangular parallelepiped with its long sides extending in the fore-and-aft direction of the vehicle 101. In this embodiment, the room housing 111 is formed to have dimensions of 3600 mm in length, 1700 mm in width, and 2580 mm in height. The room housing 111 is mainly configured with a body frame 112, a floor panel 113, a front wall panel 114, a main opening / closing door 115, side wall panels 116 and 117, a rear wall panel 118, a roof panel 119, a partition wall 120, and a toilet opening / closing door 121.

[0033] Body frame 112 is a component that supports floor panel 113, front wall panel 114, side wall panels 116 and 117, rear wall panel 118, and roof panel 119, and constitutes the framework of room housing 111. Specifically, body frame 112 is formed by assembling metal rods into a rectangular parallelepiped shape. In this case, the bottom portion of body frame 112 that supports floor panel 113 is formed by assembling metal rods into a square ladder shape in a plan view.

[0034] Furthermore, the main frame 112 is formed to have a length that is shorter than the length in the longitudinal direction (the X-axis direction in the drawing) and the length in the width direction (the Y-axis direction in the drawing) of the loading platform 103 in a plan view. In this case, the main frame 112 is formed to a length that prevents the main opening / closing door 115, which will be described later, from protruding from the rear end of the loading platform 103 when the main opening / closing door 115 is opened with the main frame 112 (portable toilet unit 110) placed on the loading platform 103. Furthermore, hanging hooks 112a made of L-shaped plates are provided on the upper ends of the support pillars at the four corners of the main frame 112 for hoisting the entire portable toilet unit 110.

[0035] The floor panels 113 are components that make up the floors of the toilet adjacent room 130 and the toilet room 140, and are made of flat panel material made of metal or resin material. The floor panels 113 are made up of one or more panel materials fixed onto the main frame 112 with fixtures such as bolts (not shown).

[0036] Front wall panel 114 is a component that makes up the front of portable toilet unit 110, and is made of a panel material formed into a flat plate from a weather-resistant metal material (such as aluminum) or a resin material (such as polycarbonate or polyvinyl chloride). Front wall panel 114 is positioned upright on the outer edge of floor panel 113, and is fixed to floor panel 113 and side wall panels 116, 117 via fasteners (not shown) such as bolts.

[0037] In this case, an opening is formed in the left wall surface of the front wall panel 114 as seen from the front, cut out in a vertically long rectangle as seen from the front, and a main opening / closing door 115 is provided in this opening. An outdoor unit 132b of the air conditioner 132 is attached to the right wall surface of the outer surface of the front wall panel 114 as seen from the front. An indoor unit 132a of the air conditioner 132 and a table 134 are attached to the left wall surface of the inner surface of the front wall panel 114 as seen from the front.

[0038] The main opening / closing door 115 is a component that opens and closes the inside of the toilet adjacent room 130 to the outside, allowing the user to enter and exit the toilet adjacent room 130, and is made of a panel material formed into a flat plate from a weather-resistant metal material (such as aluminum) or a resin material (such as polycarbonate or polyvinyl chloride). In this embodiment, the main opening / closing door 115 is made of a metal panel.

[0039] The upper and lower ends of the right edge of this main door 115 when viewed from the front are rotatably connected to the front wall panel 114 via round bars. In other words, the main door 115 is configured as a single-wing door that opens toward the outside. In this case, the main door 115 is configured to be lockable.

[0040] The side wall panels 116, 117 are components that make up the left and right side walls of the portable toilet unit 110, and are made of flat panel material made of weather-resistant metal material (such as aluminum) or resin material (such as polycarbonate or polyvinyl chloride). Of these side wall panels 116, 117, the left side wall panel 116 in a front view is provided with an adjacent room window 131, and the right side wall panel 117 in a front view is provided with an exhaust device 144. These side wall panels 116, 117 are each positioned upright on the outer edge of the floor panel 113 and are fixed to the floor panel 113, front wall panel 114, and rear wall panel 118, respectively, via fasteners such as bolts (not shown).

[0041] Rear wall panel 118 is a component that makes up the rear of portable toilet unit 110, and is composed of a flat plate-like body made of weather-resistant metal material (such as aluminum) or resin material (such as polycarbonate or polyvinyl chloride). Rear wall panel 118 is provided with a toilet room window 143, and has a rain gutter 118a attached to the upper part of its outer surface, extending in the width direction (rearward along the Y axis in the figure). Rear wall panel 118 is positioned upright on the outer edge of floor panel 113, and is fixed to floor panel 113 and side wall panels 116, 117 via fasteners (not shown) such as bolts.

[0042] Roof panel 119 is a component that forms the roof of portable toilet unit 110 and also forms the ceiling of each of toilet adjoining room 130 and toilet room 140, and is made of a panel material formed into a flat plate from a weather-resistant metal material (such as aluminum) or resin material (such as polycarbonate or polyvinyl chloride). This roof panel 119 is placed on the upper ends of front wall panel 114, side wall panels 116 and 117, and rear wall panel 118, and is attached to main frame 112 with fasteners (not shown) such as bolts.

[0043] In this case, the roof panel 119 is attached in a position that slopes downward from the front wall panel 114 toward the rear wall panel 118. That is, in this embodiment, the rear wall panel 118 is formed to be lower in height than the front wall panel 114. As a result, the ceilings in each of the toilet adjacent room 130 and the toilet room 140 also slope downward from the front wall panel 114 toward the rear wall panel 118.

[0044] Partition wall 120 is a component that separates the internal space within living room housing 111 between toilet-adjacent room 130 and toilet room 140, and is made of a panel material formed into a flat plate from a metal material (such as aluminum) or a resin material (such as polycarbonate or polyvinyl chloride). Partition wall 120 is disposed upright at the boundary between toilet-adjacent room 130 and toilet room 140 on floor panel 113, and is fixed to floor panel 113, roof panel 119, and main frame 112 via fasteners (not shown) such as bolts.

[0045] In this case, a vertically long rectangular opening is formed in the left half of the partition wall 120 when viewed from the toilet adjacent room 130 side, and this opening is provided with a toilet door 121. That is, the toilet door 121 is formed in a position opposite the main door 115 provided on the front wall panel 114.

[0046] The toilet door 121 is a component that opens and closes the toilet room 140 relative to the adjacent toilet room 130 so that the user can enter and exit the toilet room 140, and is made of a panel material formed into a flat plate from wood, metal (such as aluminum), or resin (such as polycarbonate or polyvinyl chloride). In this embodiment, the toilet door 121 is made of a wooden panel.

[0047] When viewed from the front, the upper and lower ends of the left edge of this toilet door 121 are rotatably connected to the partition wall 120 via round bars. In other words, the toilet door 121 is configured as a single-wing door that opens toward the adjacent toilet room 130. In this case, the toilet door 121 is configured to be lockable.

[0048] Toilet-adjacent room 130 is a space that functions as a rest room in portable toilet unit 110 or a waiting room when toilet room 140 is used, and is formed between front wall panel 114 and partition wall 120 within living room housing 111. In other words, toilet-adjacent room 130 is formed within living room housing 111 at a position adjacent to toilet room 140, in a state that communicates with the outside of portable toilet unit 110 via main opening / closing door 115.

[0049] More specifically, the toilet-adjacent room 130 is formed as a rectangular space in a plan view that extends elongatedly in the direction of entry and exit of the toilet door 121 (the X-axis direction in the figure). Here, a long space means that the direction of entry and exit of the toilet door 121 (the X-axis direction in the figure) is longer than the width direction (the Y-axis direction in the figure) perpendicular to the direction of entry and exit (the X-axis direction in the figure). In this embodiment, the toilet-adjacent room 130 is formed to have a floor area of ​​3.8 square meters. The toilet-adjacent room 130 is provided with an adjacent-room window 131, an indoor unit 132a of an air conditioner 132, a stool 133, a table 134, and a lighting fixture 135.

[0050] The adjacent room window 131 is a sliding window with transparent glass that allows the outside of the portable toilet unit 110 to be seen from inside the toilet adjacent room 130, and also allows the inside of the toilet adjacent room 130 to be seen from outside the portable toilet unit 110. In this case, the adjacent room window 131 is provided with a shutter 131a at the top of the window frame that can be rolled up and down to cover the adjacent room window 131. This adjacent room window 131 is formed to extend from the toilet opening / closing door 121 toward the main opening / closing door 115.

[0051] The air conditioner 132 is a mechanical device that prevents odors from inside the toilet room 140 from entering the toilet adjacent room 130 and adjusts the temperature and humidity inside the toilet adjacent room 130 and the toilet room 140. Specifically, the air conditioner 132 is mainly composed of an indoor unit 132a and an outdoor unit 132b.

[0052] The indoor unit 132a is a mechanical device installed in the toilet-adjacent room 130 that outputs cool air, warm air, or dehumidified air (hereinafter referred to as "cool air, etc."). The indoor unit 132a is installed in a position and orientation that sends cool air, etc., toward the toilet room 140. In this embodiment, the indoor unit 132a is installed in the toilet-adjacent room 130, at the top of the left half of the front wall panel 114 (at a height of approximately 180 cm, which is above the head of an adult).

[0053] In this case, indoor unit 132a can freely change the airflow direction within a range of 180° left and right relative to the front and within a range of 90° downward relative to the horizontal. Therefore, as shown in Figure 5, indoor unit 132a is installed in a position shifted to the left rather than directly in front of toilet door 121, but by adjusting the airflow direction, cool air or the like can be sent into toilet room 140 even when toilet door 121 is half-open. In addition, indoor unit 132a is operated by a remote controller (so-called remote control) (not shown), which is a remote-controlled operation device operated by the user.

[0054] The outdoor unit 132b is a box-shaped mechanical device that sends refrigerant gas through piping to the indoor unit 132a to generate cool air, warm air, or dehumidified air in the indoor unit 132a. The outdoor unit 132b is attached to the outer surface, which is the back surface of the front wall panel 114 to which the indoor unit 132a is attached.

[0055] The stool 133 is a device for a person using the toilet-adjacent room 130 to sit on. In this embodiment, the stool 133 is configured as a bench (capable of seating about four people) extending along the longitudinal direction of the toilet-adjacent room 130, and is connected to the side wall panel 117 and placed in a fixed state. It goes without saying that the stool 133 may also be placed in an unfixed state within the toilet-adjacent room 130.

[0056] The table 134 is a device on which a user can place items or write. In this embodiment, the table 134 is configured as a folding table that folds down and hangs down from the front wall panel 114. The table 134 is provided below the indoor unit 132a.

In this embodiment, the lighting fixture 135 is configured with LEDs lined up inside a housing extending in the longitudinal direction of the toilet-adjacent room 130, and is attached to the ceiling surface inside the toilet-adjacent room 130, which is the underside of the roof panel 119.

[0058] Toilet room 140 is a space in portable toilet unit 110 where people can relieve themselves, and is formed between rear wall panel 118 and partition wall 120 within living room housing 111. In other words, toilet room 140 is formed adjacent to toilet adjacent room 130 within living room housing 111, and faces main opening / closing door 115 with toilet adjacent room 130 in between.

[0059] More specifically, toilet room 140 is formed as a rectangular space in a plan view that extends elongatedly in the width direction (the Y-axis direction in the figure) of living room casing 111. In this embodiment, toilet room 140 is formed to have a floor area of ​​1.44 square meters. This toilet room 140 is provided with a toilet unit 141, a hand-washing basin 142, a toilet room window 143, an exhaust device 144, and a lighting fixture 145.

[0060] The toilet unit 141 is a device for users to relieve themselves, and is an integral unit consisting of a toilet bowl on which the user sits to relieve themselves and a waste cistern for collecting excrement. This toilet unit 141 is located on the side wall panel 117, which is the farthest back side, in the toilet room 140. In this embodiment, the toilet unit 141 is configured as a Western-style toilet that the user uses while sitting, but it goes without saying that it may also be configured as a Japanese-style toilet or urinal that the user uses while squatting. In this embodiment, the toilet unit 141 is installed on the floor panel 113, but the toilet portion may also be attached to the side wall panels 116, 117 or the rear wall panel 118.

[0061] The hand-washing basin 142 is a fixture for users to wash their hands and get dressed, and is comprised of a faucet, a water receiving bowl, a clean water tank, a drainage tank, a mirror, etc. The hand-washing basin 142 is attached to the rear wall panel 118 in a position facing the toilet door 121.

[0062] The toilet room window 143 is a sliding window with translucent glass that is installed for the purpose of letting in light or ventilation inside the toilet room 140. The toilet room window 143 is attached to the upper part of the rear wall panel 118.

[0063] The exhaust device 144 is a device that sucks air from inside the toilet room 140 and exhausts it outside the portable toilet unit 110. In this embodiment, the exhaust device 144 is configured by a ventilation fan. The exhaust device 144 is attached to the side wall panel 117 above the toilet unit 141.

[0064] The lighting fixture 145 is a fixture for illuminating the inside of the toilet room 140. In this embodiment, the lighting fixture 145 is configured with LEDs lined up inside a housing extending in the longitudinal direction of the toilet room 140, and is attached to the ceiling surface inside the toilet room 140, which is the underside of the roof panel 119. The portable toilet unit 110 is also provided with a power input section (not shown) that includes a breaker or the like for connecting an external power source to operate the air conditioner 132, the lighting fixtures 135, 145, and the exhaust device 144.

[0065] (Operation of the portable toilet unit-equipped vehicle 100) Next, the operation of the portable toilet unit-equipped vehicle 100 configured as described above will be described. First, a worker installing the portable toilet unit-equipped vehicle 100 at the installation location places the portable toilet unit 110 on the loading platform 103 of the vehicle 101. Specifically, the worker uses a forklift or crane to lift the portable toilet unit 110 and place it on the loading platform 103 of the vehicle 101. In this case, the worker places the portable toilet unit 110 on the loading platform 103 with the toilet room 140 positioned behind the driver's cab 102. The worker also secures the portable toilet unit 110 to the loading platform 103 using fasteners such as bolts or wire ropes provided on the loading platform 103.

[0066] Next, the worker moves the portable toilet unit-equipped vehicle 100 to the installation location. Specifically, the worker can move the portable toilet unit-equipped vehicle 100 by driving the vehicle 101 to the installation location. In this case, the installation location may be a construction site, a work site, various event venues, an accident or disaster site, a commercial facility, a public facility, or a nursing home. In this case, the worker closes the shutter 131a of the adjacent room window 131 to prevent damage to the adjacent room window 131 due to flying objects such as flying stones, dust, bird droppings, insects, rain, snow, or hail during transportation. In addition, the worker can prevent odors from building up in the toilet room 140 by opening the toilet room window 143.

[0067] Furthermore, in portable toilet unit-equipped vehicle 100, roof panel 119 of living room housing 111 is formed so that it continuously rises in height from the front to the rear of vehicle 101, so that air flowing from the front of vehicle 101 onto roof panel 119 presses roof panel 119 downward, thereby stabilizing portable toilet unit 110 on loading platform 103. Furthermore, in portable toilet unit-equipped vehicle 100, rear wall panel 118 is formed so that it is lower in height than front wall panel 114, so that wind resistance when portable toilet unit-equipped vehicle 100 is traveling can be reduced.

[0068] Next, when the worker has moved the portable toilet unit-equipped vehicle 100 to the installation location, he or she prepares the portable toilet unit 110 for use. Specifically, the worker restricts the movement of the portable toilet unit-equipped vehicle 100 using tire chocks (not shown) or the like, and then connects an external power source to the power input section to enable operation of the air conditioner 132, lighting fixtures 135, 145, and exhaust device 144. The worker also places a step platform S at the rear end of the loading platform 103 of the vehicle 101 to allow the user to get on and off.

[0069] Furthermore, by entering the toilet adjacent room 130 through the main opening / closing door 115 and operating the exhaust device 144 and the air conditioner 132, the air in the toilet room 140 and the toilet adjacent room 130 can be exhausted to the outside via the exhaust device 144, and the temperatures in both rooms can be made comfortable. In this case, the worker adjusts the air direction so that cool air from the indoor unit 132a is output toward the toilet opening / closing door 121 (see FIG. 5). In this way, the worker can prepare the portable toilet unit 110 for use at the installation location of the portable toilet unit-equipped vehicle 100.

[0070] Next, the user climbs up from the step platform S to the rear end of the loading platform 103, and then opens the main opening / closing door 115 to enter the adjacent-toilet room 130. The user can also take a rest in the adjacent-toilet room 130, or proceed to the back of the adjacent-toilet room 130, open the opening / closing toilet door 121, and use the toilet room 140 to relieve themselves. In this case, regardless of the operating status of the exhaust device 144, the portable toilet unit 110 outputs cool air from the indoor unit 132a toward the opening / closing toilet door 121, thereby preventing odors from within the toilet room 140 from flowing into the adjacent-toilet room 130 (see FIG. 5).

[0071] Furthermore, if toilet room 140 is in use and more persons U1-U4 wishing to use toilet room 140 enter adjacent toilet room 130, the next users U1-U4 can naturally form a queue by lining up along the direction in which adjacent toilet room 130 extends, since adjacent toilet room 130 extends long along the direction of entry and exit (X-axis direction) of toilet opening and closing door 121 (see FIG. 4). In this case, adjacent room window 131 of portable toilet unit 110 is formed to extend from toilet opening and closing door 121 toward main opening and closing door 115, so a person outside portable toilet unit 110 can check the occupancy level of toilet room 140 from the outside through adjacent room window 131.

[0072] Next, when removing the portable toilet unit-equipped vehicle 100, the worker stops the operation of the lighting fixtures 135, 145 and the exhaust device 144, and then disconnects the external power supply from the power input section. The worker also removes the step platform S and the tire chocks to enable the vehicle 101 to move. The worker can then drive the vehicle 101 to remove the portable toilet unit-equipped vehicle 100 from the installation location. The worker can also use a forklift or crane to lift the portable toilet unit 110 and remove it from the loading platform 103 of the vehicle 101.

[0073] In this embodiment, the portable toilet unit 110 is used while placed on the loading platform 103 of the vehicle 101. However, the portable toilet unit 110 can also be removed from the loading platform 103 of the vehicle 101 and installed at an installation location for use.

[0074] As can be understood from the above operation description, according to the above embodiment, the vehicle 100 equipped with a portable toilet unit is equipped with an air conditioner 132 that forcibly blows air toward the toilet opening / closing door 121 into the toilet adjacent room 130 adjacent to the toilet room 140, thereby preventing odors from within the toilet room 140 from directly entering the toilet adjacent room 130, allowing the entire portable toilet unit 110 to be made smaller and each room, such as the toilet room 140 or the toilet adjacent room 130, to be made larger, while also allowing for greater freedom in the layout of each of these rooms.

[0075] Furthermore, the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the scope of the present invention. In the description of each modification, the same parts as those in the above-described embodiment are designated by the same reference numerals, and redundant description will be omitted.

[0076] For example, in the above embodiment, portable toilet unit 110 is configured to include air conditioner 132 in toilet adjacent room 130 and to output cool air, etc., toward toilet door 121. However, portable toilet unit 110 may be configured to include a blower that forcibly blows air into toilet adjacent room 130 toward the toilet entrance. In other words, air conditioner 132 corresponds to the blower according to the present invention. Therefore, portable toilet unit 110 can also be configured to include a blower that simply outputs air, such as an electric fan, in toilet adjacent room 130 instead of or in addition to air conditioner 132, and to output air toward toilet door 121.

[0077] Furthermore, in the above embodiment, the air conditioner 132 is provided at a position offset in the Y-axis direction from the toilet door 121. This allows the air conditioner 132 to send air toward the toilet room 140 even when the toilet door 121 is half-open. However, as shown in FIG. 6, the air conditioner 132 can also be provided on the side wall panel 117 so as to send air toward the toilet door 121. In this way, by providing the indoor unit 132a on a wall panel in the shorter direction (in the above embodiment, on a wall panel in the longer direction) from the toilet door 121 in the toilet adjacent room 130, it is possible to send air with reduced temperature changes, such as cool air, to the toilet room 140. It goes without saying that the air conditioner 132 may also be provided at a position opposite the toilet door 121.

[0078] Furthermore, in the above embodiment, the toilet room 140 is configured to include the toilet room window 143 and the exhaust device 144 so that air within the toilet room 140 can be exhausted to the outside. In other words, the toilet room window 143 and the exhaust device 144 correspond to the ventilation opening according to the present invention. However, this ventilation opening may be configured as either the toilet room window 143 or the exhaust device 144 alone, or the configuration of the toilet room window 143 and the exhaust device 144, for example, a ventilation opening that constantly connects the toilet room 140 to the outside, may also be used. The portable toilet unit 110 may also be configured without a ventilation opening. Furthermore, the portable toilet unit 110 may be provided with the exhaust device 144 or a ventilation opening in the toilet adjacent room 130, but it is preferable that only the ventilation opening in the toilet adjacent room 130 be connected to the outside when the air conditioner 132 is operated.

[0079] Furthermore, in the above embodiment, portable toilet unit 110 is provided with toilet door 121 for entering and exiting toilet room 140 from toilet adjacent room 130. In other words, toilet door 121 corresponds to the toilet entrance / exit according to the present invention. However, portable toilet unit 110 can also omit toilet door 121 and configure the toilet entrance / exit as a simple opening.

[0080] Furthermore, in the above embodiment, portable toilet unit 110 is provided with main opening / closing door 115 for entering and exiting from toilet adjacent room 130 to the outside. In other words, main opening / closing door 115 corresponds to the main entrance / exit according to the present invention. However, portable toilet unit 110 may also be configured so that main opening / exit door 115 is omitted and the main entrance / exit is simply an opening. Also, portable toilet unit 110 may be configured so that a separate room is provided in addition to toilet adjacent room 130, and a main entrance / exit including main opening / closing door 115 is provided in this separate room.

[0081] Furthermore, in the above embodiment, the portable toilet unit 110 is configured with the toilet door 121 (toilet entrance) located in a position opposite the main door 115 (main entrance). However, the portable toilet unit 110 can also be configured with the toilet door 121 (toilet entrance) located in a position other than the position opposite the main door 115 (main entrance).

[0082] Furthermore, in the above embodiment, the toilet adjacent room 130 is formed to extend elongatedly along the entrance / exit direction of the toilet opening / closing door 121. Here, "the toilet adjacent room 130 is formed to extend elongatedly along the entrance / exit direction of the toilet opening / closing door 121" means that the length of the living space of the toilet adjacent room 130 in the entrance / exit direction (the X-axis direction in the figure) is formed to be longer than the width direction length in the direction perpendicular to this entrance / exit direction (the Y-axis direction in the figure). However, the toilet adjacent room 130 can also be formed to extend elongatedly along the width direction perpendicular to the entrance / exit direction of the toilet opening / closing door 121.

[0083] In the above embodiment, the toilet-adjacent room 130 is configured with the adjacent room window 131 provided in the side wall panel 116. However, the toilet-adjacent room 130 may be configured with the adjacent room window 131 provided in the side wall panel 117 or the front wall panel 114 instead of or in addition to the side wall panel 116, or the adjacent room window 131 may be omitted. Also, the adjacent room window 131 may be configured without the shutter 131a.

[0084] Furthermore, in the above embodiment, the portable toilet unit-equipped vehicle 100 is configured such that the toilet room 140 is located behind the driver's cab 102. That is, the living room housing 111 has the toilet room 140 formed at the innermost portion relative to the main opening / closing door 115. In this case, the living room housing 111 has a floor area of ​​1.44 square meters, which is larger than the 1.28 square meters of a typical toilet room in a typical detached house, by forming the toilet room 140 using the entire width of the living room housing 111. However, it goes without saying that the toilet room 140 can be formed in any position and size within the living room housing 111. For example, the portable toilet unit-equipped vehicle 100 can also be configured such that the toilet adjacent room 130 is located behind the driver's cab 102 and the toilet room 140 is located on the rear side of the cargo bed 103. In this case, the portable toilet unit 110 can be configured such that the main opening / closing door 115 is provided on the side wall panels 116, 117 that form the toilet adjacent room 130.

[0085] Furthermore, in the above embodiment, the toilet-adjacent room 130 is formed adjacent to the toilet room 140 using the same overall width of the living room casing 111 as the toilet room 140, thereby ensuring a floor area of ​​3.8 square meters, which is larger than 1 tsubo (3.3 square meters). However, it goes without saying that the toilet-adjacent room 130 can be formed in any position and size within the living room casing 111.

[0086] Furthermore, living room housing 111 forms toilet room 140 at the innermost part of living room housing 111 across the full width of living room housing 111, and forms toilet-adjacent room 130 adjacent to this toilet room 140 across the full width of living room housing 111, so that living room housing 111 as a whole on cargo bed 103 is large enough to accommodate toilet-adjacent room 130 and toilet room 140 while also ensuring free space 103a on cargo bed 103. This allows portable toilet unit-equipped vehicle 100 to ensure free space 103a for utility use on cargo bed 103 while configuring living room housing 111 with a necessary and sufficient size. However, living room housing 111 may naturally be formed in a size that can be placed on the entire floor surface of cargo bed 103.

[0087] In the above embodiment, the roof panel 119 is formed to be higher from the front side toward the rear side (front wall panel 114) of the vehicle 101. However, the roof panel 119 may be configured to be inclined toward a wall panel other than the front wall panel 114, or may be configured in a horizontal position.

[0088] In the above embodiment, the main door 115 and the toilet door 121 are configured as single-wing doors. However, the main door 115 and the toilet door 121 may be configured as double-wing doors or as sliding doors.

[0089] In the above embodiment, the vehicle 101 is configured as a 2-ton long truck. However, it goes without saying that the vehicle 101 may be configured as a truck of a size other than a 2-ton long truck, such as a 2-ton short truck, a 2-ton wide truck, or a 3-ton truck.
