Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automobile having a kitchen, a toilet and a shower facility in a vehicle interior.

[0002]

[Prior art and problems]

 In recent years, buses with kitchens, toilets, showers, etc., especially small buses, have been provided in the passenger compartment.

The tank positions of those baths are restricted in layout due to water supply. In other words, it is necessary to select a lower position because the water supply from the water supply by hand will deteriorate if placed in a higher position, but there is currently no space.

[0004]

[Problems to be solved by the device]

 Therefore, it is an object of the present invention to provide a tank mounted on a vehicle and a water supply apparatus for the tank, which has a good water supply at a low position and has a simple vehicle layout.

[0005]

[Means for Solving the Problems]

 According to the present invention, in an automobile having a kitchen, a toilet, and a shower facility in a vehicle compartment, a fresh water tank is installed under a sofa, a dirty water tank is installed under the floor, and a water pump with a water faucet is installed. The suction side is connected to a fresh water tank by a water circuit via a strainer and a water supply valve, and the discharge side is connected to a water circuit via a pressure reducing valve to supply water to the shower, etc. and a water circuit to supply water to the shower etc. via a water heater. A wastewater tank is installed to store used wastewater.

[0006]

[Action]

 Therefore, the fresh water tank is installed under the sofa, which is convenient for the layout, and the water hose is connected to the faucet provided in the water pump installed in the lower position to supply water at the water pressure of the fresh water tank. Is supplied to the necessary places such as toilets and showers by a water pump.

Therefore, the layout of the vehicle becomes easy and the water supply is good.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a bus 1. Sofas 2 are provided on both sides of a rear half of a floor 12, and a lower part of the sofa 2 is referred to with reference to FIGS. 2, 3, and 4. , A fresh water tank 3 is attached to the floor 12.

Reference numeral 3a indicates a socket for piping.

A toilet 4, a kitchen 6 and a shower booth 5 are provided at the rear end of the vehicle. Under the floor, a sewage tank 10 is provided between the frames, and a water pump 11 is provided outside the frame (on the left side in the illustrated example). A water heater 16 is attached.

Seats 7 and 8 and a driver seat 9 are provided in the front half of the floor 12.

Further, in FIG. 5, the fresh water tank 3 is connected to the water intake port 11c of the water pump 11 by a water circuit via a water supply valve 17 and a strainer 18, and referring to FIGS. The discharge port 11d of the pump 11 is connected to a water tap 25 for a shower or a toilet via a pressure reducing valve 19.

Further, the water heater 16 is connected to a hot water tap 26 of a shower or a kitchen.

Here, reference numerals 11 b and 14 denote safety valves, reference numerals 20 to 22 denote drain valves, respectively, which are connected to the sewage tank 10, and reference numeral 11 a denotes a water tap provided in the water pump 11. Is shown.

Although not shown in order to avoid complication of the drawing, drainage used for toilets, showers, kitchens, etc. is connected by a water circuit so as to be drained to a dirty water tank.

Therefore, in a place where there is a water supply such as a garage, a hose can be connected to the water tap 11a of the water pump 11 to easily supply water to the fresh water tank 3 with the water pressure of the water supply. Water can be supplied and hot water can also be supplied via a heater.

Further, the position of the fresh water tank has a wide selectivity, and does not become a constraint on the vehicle layout.

The drain valves 20 to 22 are provided for the maintenance of the water supply device and have no relation to the operation during use.

[0020]

[Effect of device]

 Since the present invention is configured as described above, the position and shape of the fresh water tank are not a constraint on the vehicle layout, and the water supply position is low, so the work is easy.
