The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 and 2, in a conventional hotel room toilet, a toilet room, a shower area and a washing area are of a three-in-one structure in the same space, the shower area is arranged close to a passageway 001, and is separated from the toilet room and the washing area by adopting a glass partition, and a pre-feeling 003 is arranged at the rear side of a room door 002. The water supply mode of the toilet is mainly that a water supply pipe 015 is embedded in a wall removing mode, and a toilet water tank 014 is covered by a face brick. The drainage mode of hotel toilets generally adopts interlayer drainage, specifically, a 013 channel of drainage pipe is laid below a lower floor, an access pipe well 004 is arranged, an access door 008 is arranged at the side of the access pipe well 004, a sewage vertical pipe 005, an exhaust vertical pipe 006 and a wastewater vertical pipe 007 are arranged inside the access pipe well, drainage pipes of sanitary appliances such as a toilet 010, a shower bath 009 and a hand basin 011 penetrate through the floor to enter a lower-layer space, the drainage vertical pipe 012 is inserted into the lower-layer floor space, and the sanitary appliances need to enter the lower-layer hotel toilets to maintain and overhaul in a ceiling and a public pipe well when a fault occurs.

The defect that two guest rooms cannot be used due to the fact that the lower layer is easy to leak in the interlayer drainage mode conventionally adopted by the existing hotel guest rooms and needs to enter the hotel toilet at the lower layer for overhauling is overcome. As shown in fig. 3 and 4, a water supply and drainage system for hotel toilets is provided, which mainly comprises two parts, namely a guest room toilet 200 close to the side of a guest room aisle 100 and a lower drainage external pipe inspection ditch 300 correspondingly arranged at the bottom of a floor slab of the guest room toilet 200, wherein at least the floor slabs of the guest room aisle 100 and the guest room toilet 200 are floor slabs in a shape like a Chinese character 'jing' to save the beam height and adapt to a centralized air-conditioning pipeline which may appear in the ceiling of the guest room aisle 100. Every hotel guest room corresponds and has set an independence guest room bathroom 200, guest room bathroom 200 is whole to be the rectangle structure, is close to guest room door and lies in being close to guest room pavement 100 side of guest room, just closestool outlet 201, shower outlet 202 and the wash-basin outlet 206 in the guest room bathroom 200 are close to the long limit in its outside and arrange.

The lower drainage outer inspection pipe ditch 300 is open in side and located at the outer side position below the guest room toilet 200, and is used for arranging water supply and drainage pipes of the guest room toilet 200 such as the toilet drain port 201, the rain drain port 202 and the hand basin drain port 206, and the toilet drain port 201, the rain drain port 202 and the hand basin drain port 206 are correspondingly connected with a sewage pipeline 304 and a waste water pipeline 305 which are transversely laid in the lower drainage outer inspection pipe ditch 300 through pipelines penetrating through the floor of the toilet.

Specifically, the side opening of lower drainage outward survey pipe ditch 300 is seted up in the wall body top of guest room pavement 100 one side is to upper strata bathroom floor, do not get into in the guest room of lower floor alright overhaul the guest room bathroom 200 of upper strata in the guest room pavement 100 of lower floor, and overhaul and can not destroy the floor waterproof layer of guest room bathroom 200, prolonged the hotel bathroom and used the life, do not disturb guest's life yet, greatly improve hotel bathroom and give the reliability and the economic nature of drainage technique.

In some embodiments, in order to overcome the defects that the existing hotel guest room water supply pipes are all constructed in a way of wall surface groove removal and pipe burying, structures are possibly damaged, and the safety of a house is affected, as shown in fig. 3, 4 and 13, the water supply pipes of the guest room toilet 200 are all arranged on the wall body outside the guest room walkway 100 to form an external inspection water supply pipe which is vertically arranged, a water outlet at the lower end of the external inspection water supply pipe is correspondingly connected with a toilet, a shower and a hand basin in the guest room toilet 200, and a water inlet at the upper end of the external inspection water supply pipe is correspondingly connected with a horizontal hot water supply pipe 301 and a horizontal cold water supply pipe 302 which are transversely paved in the lower drainage external inspection pipe ditch 300.

The horizontal hot water supply pipe 301, the horizontal cold water supply pipe 302 and the vertical external inspection water supply pipes are arranged on the side of the guest room walkway 100, and the horizontal hot water supply pipe 301, the horizontal cold water supply pipe 302 and the vertical external inspection water supply pipes can be directly overhauled and maintained in the guest room walkway 100 without entering the guest room toilet 200 on the lower layer.

In some embodiments, as shown in fig. 3, 4, 7, 8 and 13, the external water supply pipes respectively include a cold shower water supply vertical pipe 101, a hot shower water supply vertical pipe 102, a toilet water supply vertical pipe 103, a cold wash basin water supply vertical pipe 104 and a hot wash basin water supply vertical pipe 105 which are vertically spaced, the cold shower water supply vertical pipe 101 and the hot shower water supply vertical pipe 102 are arranged side by side on a walkway wall corresponding to a shower area side of the guest room toilet 200, the toilet water supply vertical pipe 103 is arranged on a walkway wall corresponding to a toilet bowl side of the guest room toilet 200, and the cold wash basin water supply vertical pipe 104 and the hot wash basin water supply vertical pipe 105 are arranged side by side on a walkway wall corresponding to a wash basin drain 206 side, so as to supply water to the toilet.
