Electronic toilet seat with water heating seat cushion

Abstract

The invention disclose an electronic toilet seat with water heating seat cushion, which comprises: a body; a heating water tank which is positioned inside the body; a seat cushion which is positioned outside the body and an inner cavity of which is annularly perforated; a seat cushion inner cavity water feeding pipe which is connected with an outlet of the heating water tank and a seat cushion inner cavity water feeding connecting port; at least one seat cushion inner cavity exhaust pipe one end of which is communicated with the inner cavity of the seat cushion, a communication port of which is positioned at the rear part of the inner cavity of the seat cushion and the other end of which is communicated with the heating water tank; a seat cushion water returning pipe which is communicatedwith the seat cushion inner cavity water drainage connecting port and the heating water tank, wherein both the water feeding connecting port and the water drainage connection port are positioned at the rear part of the inner cavity of the seat cushion; the electronic toilet seat is characterized by further comprising a guide pipe positioned inside the inner cavity of the seat cushion, one end port of the guide pipe is communicated with the water feeding connecting port, and the other end port of the guide pipe stretches to the front part of the inner cavity of the seat cushion. With the help of the improvement, the gas inside the inner cavity of the seat cushion can be better exhausted during water filling so that the seat ring better keeps warm uniformly and the capacity of the inner cavity of the seat cushion is fully utilized, besides, the cost is low.

Description

Technical field [0001] The present invention relates to an electronic toilet seat which is installed on the toilet to form the "electronic toilet" in the national standard GB4706.53-2002 and has a water heating cushion. In the international patent classification table, the classification can belong to E03D9 / 08. Background technique [0002] The previous application ZL200620063475.6 and CN101403239A proposed a technical solution for the electronic toilet seat of the so-called washable sanitary ware to form the annular seat cushion into a closed annular cavity to store the hot water used by the water spray system. This solution uses clean hot water to warm the seat cushion and expands the hot water storage capacity, thus reducing the volume of the heating water tank and its console. The earlier application therefore also called the inner cavity of the seat cushion an expansion tank. After that, the first application CN200810167730.5 proposed an improvement to the exhaust problem o...

Problems solved by technology

However, according to the analysis of the running test, the exhaust port in the water inlet area connected to the first exhaust pipe in the inner cavity of the seat cushion is easily submerged by the water entering the adjacent water inlet and loses the exhaust function. There is a partition between the water inlet area and the water outlet area at the rear of the cavity to separate the annular cavity, so that the air on the side of the water inlet 1 at the rear of the seat cushion inner cavity can only be squeezed to the front of the seat cushion inner cavity first, and then squeezed to the front of the seat cushion inner cavity. To the side of the water outlet 1 at the rear of the seat cushion inner cavity, it is discharged through the exhaust port connected to the second exhaust pipe located in the water outlet area

The exhaust path is greatly increased, and all the air must be discharged from the exhaust port connected to the second exhaust pipe located in the water outlet area, and the exhaust resistance increases accordingly, so the air that cannot be discharged smoothly will affect the interior of the seat cushion. water-filled state
