Description

Folding hand basin

Technical field

The invention relates to the field of product folding design, in particular to a folding hand basin.

Background technique

With the rapid increase in the global population and the reduction of resources, the living space per capita is getting smaller and smaller, especially in large and medium-sized cities with dense population, or special occasions such as small room hotels, small capsule apartments, travel cars, small yachts, etc. limited. Therefore, in the case of limited use space, this requires us to make reasonable and effective use of product materials, maximize the efficiency of space use, and not occupy excessive use space when designing industrial products that are closely related to people's lives. Folding furniture breaks through the design pattern of traditional furniture. By folding, the area or bulky items can be compressed as much as possible, which can make room for the living room and is favored by consumers.

Sinks are generally used to collect and drain sewage when washing hands and rinsing. After people finish washing their hands and gargle, most of the time, the sinks have almost lost their function, and in today's space resources are limited. Under, it also takes up a lot of space. Therefore, people have invented a foldable sink, which is designed to be used when the sink is needed. When the sink is not needed, it is folded to save space. There are related design studies in China.

For example, the utility model patent of the application No. 201420223362.2 discloses a manual and electric folding type hand washing table. The technical scheme of the hand washing table is: an "L" shaped sliding plate is embedded in the slideway, and one end of the supporting arm is connected with the hand basin, and One end is connected with the slide plate, and there are telescopic lock heads on the boards on both sides of the box body. Usually, the hand basin is contracted into the "mouth" shape box body, and the hand basin can be pulled up manually by the manpower, and the slide plate is driven on the slide path by the support arm. Sliding, the basin rises to a high place, and then the entire basin is hung on the telescopic head through the "L"-shaped "one" hook, so that it is used like a normal basin, when the handle basin needs to be retracted back to the word "mouth" The shape of the box body, the pull ring is pulled by hand, the pull ring drives the two lock heads to shrink by the pull wire, the hook is taken off, and the water basin is retracted into the box body, and the utility model has the advantages of being atmospheric, convenient to use and space saving. The utility model patent No. 03242776.X discloses a sanitary ware which is combined with a sink and a toilet. The sanitary ware comprises a sink and a toilet, and the hand basin is connected with the upper part of the water storage tank through a folder. The sink is connected by a folder that can be leveld up to 90 degrees. The level of the sink is up to 90 degrees, and the water inlet switch group and the drain switch can be controlled by the connection of the folder. The water inlet switch group includes the water inlet switch and the water outlet switch. Since the hand basin is connected to the upper part of the water storage tank through the folder, when the hand basin is in the horizontal position above the toilet water storage tank, the water inlet switch of the water inlet linkage switch group is closed, and the water outlet switch of the water inlet linkage switch group is received by the water storage tank. When the water level float is controlled, when the float ball is higher than the water level line of the water storage tank, the water outlet switch of the water inlet linkage switch group is closed, and vice versa. The waste water in the sink directly flows into the water storage tank through the drain hole of the hand basin. When the waste water reaches the water level line, the water outlet switch of the water inlet switch group is closed, and the waste water exceeds the water level. When the line is used, excess waste water flows into the toilet from the overflow pipe of the water storage tank; when the toilet is used, the hand washing pool is folded 90 degrees by the folder, and the water inlet switch of the water inlet switch group is driven by the folder, if the water tank When the water is insufficient, water is supplied to the water storage tank through the water inlet switch group, and the drainage linkage switch is connected by the folder; after the toilet is used, the hand basin is only pulled down to the horizontal position, and the folder drives the drainage linkage switch to open the drainage. The mouth (44) flushes the toilet. The utility model can effectively save the area of the bathroom and save water.

In summary, the currently reported folding sinks can save space to a certain extent, but because the designed sinks are hard entities with a certain spatial structure, they occupy a large area and can save space after folding. It is still very limited, and the structure is complicated and the cost is high.
