Description

Technical Field

[0001] This utility model relates to the field of RV technology, specifically to a sunken toilet, an expandable room, and an expandable RV. Background Technology

[0002] This section introduces background technology that may be related to various aspects of the embodiments of this utility model, which is believed to provide useful background information to help readers better understand the various aspects of the embodiments of this utility model. Therefore, it is understood that the description in this section is for the above purposes and does not constitute an admission of the prior art.

[0003] With the rapid development of society and the economy, people's living standards are constantly improving, and more and more people enjoy self-driving tours. Motorhomes, due to their convenience and comfort, have become the first choice for self-driving tours. A motorhome, also known as a "home on wheels," combines the functions of a "house" and a "vehicle," but its primary attribute is still that of a vehicle—a mobile vehicle with the basic facilities necessary for home living. Due to height and width restrictions on motorhome operation, their size is limited. Motorhomes are generally fixed, and their overall size limitation results in a relatively small interior space. When people use motorhomes for travel, they need to use the toilet for washing and showering. While meeting the main functions and comfort of seating and accommodation, motorhome design often sacrifices toilet and shower functions. Some motorhomes do have toilets, but the space is too small to meet the standard size requirements of a normal toilet, making users feel cramped.

[0004] Currently, RV bathrooms combine showers, sinks, and toilets into a single space. With just one washbasin, one can only stand in the remaining area of ​​the bathroom, which is at the edge, making it impossible to stand upright as shoulders and arms constantly bump against the walls. Therefore, most existing RVs have limited space, making it impossible to create a comfortable bathroom while still providing adequate seating and resting space. Utility Model Content

[0047] like Figures 1 to 13 As shown in this embodiment of the invention, to further enhance practicality, the toilet compartment body 1 also includes a storage compartment 14. The inner diameter of the storage compartment 14 is larger than the outer diameter of the expansion compartment 3, and a shelf 141 is provided at the junction of the storage compartment 14 and the expansion compartment 3. After the expansion compartment 3 is extended, there is sufficient space for movement, allowing the user to stand inside the toilet compartment body 1. During use, the user's shoulders and arms will not touch the inner wall of the storage compartment 14, and other activities will not cause them to bump into the toilet walls. Meanwhile, various toiletries can be placed on the shelf 141, improving space utilization.

[0048] like Figures 1 to 13 As shown in this embodiment of the invention, a user access window 100 is provided on the side wall of the toilet compartment body 1, and a closing door 111 is provided on the access window. A toilet 39 or a squat toilet, or other sanitary equipment, can be installed inside the extended compartment 3.

[0049] In this embodiment of the utility model, to further demonstrate the advanced nature of the sunken toilet provided by the utility model, this embodiment of the utility model also provides an expandable room, including a compartment, wherein an expandable toilet is provided inside the compartment, and the expandable toilet is the aforementioned sunken toilet.

[0050] In this embodiment of the present invention, to further demonstrate the advanced nature of the expandable cabin provided by the present invention, this embodiment of the present invention also provides an expandable RV, including a vehicle body and a cabin fixed on the vehicle body, wherein the cabin is the aforementioned expandable cabin.

[0051] In summary, the sunken toilet, expandable cabin, and expandable RV provided by this utility model embodiment utilize the bottom space of the toilet, extending the bottom space downwards.
