Description

A foldable washbasin

technical field

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

Background technique

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

The washbasin is generally used to collect and drain sewage when people wash their hands and rinse their mouths. After people wash their hands and rinse their mouths, most of the time, the washbasin almost loses its function, and in today’s limited space resources. It also takes up a lot of space. Therefore, people have invented a collapsible washbasin, which is intended to be deployed when the washbasin is needed, and to be folded when the washbasin is not needed to save space. There are related design studies in China now.

For example, the utility model patent with the application number of 201420223362.2 discloses a manual and electric folding washstand. One end is connected to the skateboard, and there are telescopic locks on the boards on both sides of the box. Usually, the sink shrinks into the "mouth"-shaped box. When using it, the sink can be pulled up by manpower, and the skateboard is driven on the slide by the support arm. Sliding, the water basin rises to a high place, and then hangs the whole water basin on the telescopic head through the "L"-shaped "one" hook, so that it can be used like an ordinary water basin. When it is necessary to shrink the hand basin back to the "mouth" Shape the box body, pull the pull ring by hand, the pull ring drives the two locks to shrink through the pull wire, the hook is taken off, and the water basin retracts into the box body. The utility model has the advantages of atmosphere, convenient use and space saving. The utility model patent with application number 03242776.X discloses a sanitary ware combined with a washbasin and a flush toilet. The sanitary ware includes a washbasin and a toilet. The washbasin communicates with the top of the water storage tank through a folder. The washbasin is connected by a folder, and the washbasin can be used for activities from horizontal to vertical 90 degrees. The level of the washbasin is upright to 90 degrees, and the water inlet linkage switch group and the drainage linkage switch group can be controlled through the connection of the folder. The water inlet linkage switch group includes a water inlet switch and a water outlet switch. Because the washbasin communicates with the top of the water storage tank through the folder, when the washbasin 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 controlled by the water storage tank. Water level float control, when the float 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, otherwise it is opened. The waste water in the sink flows directly into the water storage tank through the drain hole of the sink. When the waste water reaches the water level, the outlet switch of the water inlet linkage switch group is turned off. When the waste water exceeds the water level, the excess waste water flows into the toilet from the overflow pipe of the water storage tank. ;When using the toilet, fold the sink by 90 degrees through the folder, and the water inlet switch of the water inlet linkage switch group is opened by the folder. The water supply and drainage interlocking switch are driven and connected by the folder; after the toilet is used, only the sink is pulled down to a horizontal position, and the folder drives the drainage interlocking switch to open the drain port (44) to flush the toilet. The utility model can effectively save the area of the toilet and save water.

To sum up, the currently reported folding washbasins can save space to a certain extent, but because the designed washbasins are hard entities with a certain spatial structure and occupy a large area, the space saved after folding Still very limited, and the structure is complicated, and the cost is high.
