Abstract

The present utility model relates to a toilet. The toilet comprises: a seat body having a sewage accommodating bowl; a ring flushing pipeline, the ring flushing pipeline being used for performing ring flushing on the sewage accommodating bowl; a bottom flushing pipeline, the bottom flushing pipeline being used for performing bottom flushing on the sewage accommodating bowl; and a flush valve, the flush valve being capable of being in fluid communication with at least one of the ring flushing pipeline and the bottom flushing pipeline, such that water for flushing flows to the sewage accommodating bowl via the flush valve. A first power supply apparatus is arranged in the seat body, and the first power supply apparatus is configured to supply power to the flush valve. By "sinking" the power supply apparatus which supplies power to the flush valve to the seat body of the toilet, the flexibility of supplying power to the flush valve and the flexibility of the arrangement of the power supply apparatus are achieved, thereby avoiding problems such as a layout difficulty or an electrical safety issue caused by concentrating electronic devices on a toilet lid or other positions.

Abstract

The present invention relates to a method for manufacturing a toilet blank. The manufacturing method includes the following steps: a grouting step: producing a seat blank, an inner container blank and a main body blank; a first demolding step: demolding a part of a main body mold, a part of an inner container mold and a part of a seat mold; a first bonding step: bonding a first bonding surface of the inner container blank and a bonding surface of the main body blank to each other; a second demolding step: demolding another part of the inner container mold from the inner container blank; a second bonding step: bonding a bonding surface of the seat blank and a second bonding surface of the inner container blank to each other; and a third demolding step: demolding demolded parts of the seat mold, the inner container mold and the main body mold from a bonded toilet blank. By bonding the blanks to each other with parts of the molds not demolded, the contact of an operator with the blanks is reduced during bonding, and the blanks can be accurately located relative to each other using the parts of the molds.
