Description

本発明は、洗面器に関する。 The present invention relates to a washbasin.

従来、カウンター等の支持部材に周縁部を載置した状態で設置されるベッセル式の洗面器として、例えば特許文献１に示すような洗面ボウル部と、この洗面ボウル部の外周部に連設されるとともに、下端部で支持部材に載置される外側部と、を備えた陶器製の洗面器が知られている。 Conventionally, as a vessel-type wash basin installed with a peripheral portion placed on a support member such as a counter, for example, a wash basin portion as shown in Patent Document 1 and a wash basin portion are connected to the outer peripheral portion of the wash basin portion. In addition, a pottery wash basin having an outer portion mounted on a support member at the lower end portion is known.

このような陶器製の洗面器では、洗面ボウル部の温度が低い場合に洗面ボウル部内に熱湯を入れることにより熱収縮が生じて割れるといったヒートショック対策や、製造過程における焼成時の切れ対策として、洗面ボウル部内の角部の曲率半径を大きくすることで応力の分散を図っている。 In such a pottery wash basin, when the temperature of the wash basin is low, hot water is put into the wash basin to cause heat shrinkage and cracking, which is a measure against heat shock and a measure against cutting during firing in the manufacturing process. Stress is dispersed by increasing the radius of curvature of the corners inside the washbasin.

しかしながら、上述した陶器製の洗面器では、ヒートショックによる割れ対策や焼成時の切れ対策として洗面ボウル部内の角部の曲率半径を大きくすることが行われているが、曲率半径を大きくした分、外側部の内側面が内側に張り出すこととなり、洗面ボウル部の容積が小さくなるという問題があった。
また、近年では洗面器のデザインとしてシャープ感が要求されるケースが多くなっているが、上方から見た平面視で洗面ボウル部の角部の曲率半径を大きくすることで、とくに外側部部分のシャープ感がなくなり、洗面器全体の外観が低下していた。 However, in the above-mentioned pottery wash basin, the radius of curvature of the corners in the wash basin is increased as a measure against cracking due to heat shock and a measure against cutting during firing. There is a problem that the inner surface of the outer portion projects inward and the volume of the washbasin bowl portion becomes smaller.
Also, in recent years, there are many cases where a sharp feeling is required for the design of the washbasin, but by increasing the radius of curvature of the corner of the washbasin in a plan view from above, especially the outer part The sharpness disappeared, and the appearance of the entire washbasin deteriorated.

本発明は、上述する問題点に鑑みてなされたもので、焼成時の切れやヒートショックによる陶器の割れを防止できるうえ、洗面ボウル部の容量を大きくすることができ、外観をシャープなデザインにすることができる洗面器を提供することを目的とする。 The present invention has been made in view of the above-mentioned problems, and it is possible to prevent the pottery from being cracked due to cutting during firing or heat shock, and it is possible to increase the capacity of the washbasin portion, resulting in a sharp appearance. The purpose is to provide a washbasin that can be used.
