Technical Field

The utility model relates to an electronic toilet, its IPC classification number is E03D9/08 (20060101).

Background

Current intelligent toilet bowl as described in prior patent with publication No. CN101886420B, it possesses the functions of buttocks washing, female washing (bidet) and enema (intestinal tract washing). In order to increase the automatic cleaning function of the nozzle, the existing design is improved by arranging a self-cleaning water outlet hole V1 on the valve 1 'and arranging a self-cleaning device 4' at the nozzle, as shown in figure 1. Wherein, the self-cleaning water outlet hole V1 of the valve 1 'is communicated with the water inlet V1' of the self-cleaning device. In the standby state, when the user selects the bowel cleansing function, the movement of the valve is as shown in fig. 2. In the standby state, the position of the shutter axial through hole 2.1 'is shown in fig. 2 a'. When the user selects the intestinal tract cleaning function, the axial through hole 2.1 ' of the opening and closing part rotates to the position b ' in the figure 2, water is guided to the self-cleaning device 4 ' through the valve 1 ' to perform self-cleaning on the nozzle 3 ', then the nozzle starts to extend, the axial through hole 2.1 ' continues to stay at the position b ' in the figure 2, the valve 1 ' keeps guiding the water to the self-cleaning device 3 ' to perform cleaning on the spray pipe, when the nozzle extends to the command position, the axial through hole 2.1 ' starts to rotate to the position of the intestinal tract cleaning hole V3, finally the hole rotates to the position e ' in the figure 2, and the water is conducted to the intestinal tract cleaning nozzle V3 ' of the nozzle through the valve 1 ' to be sprayed. In the above process, the axial through hole 2.1 ' of the opening and closing member passes through the woman washing water hole V2 shown in fig. 2 c ' and the adjacent area between the woman washing water hole d ' shown in fig. 2 and the intestinal tract, so that water is firstly sprayed out from the woman washing nozzle V2 ' of the nozzle, then water spraying is stopped, and finally water is sprayed out from the intestinal tract cleaning nozzle V3 '. In the cleaning process, after the self-cleaning device performs self-cleaning on the nozzle and the spray pipe, the water pressure sprayed out of the nozzle is discontinuous and abrupt, so that the cleaning comfort of a user is influenced.

And because the apertures and the positions of the gynecological washing nozzle and the intestinal nozzle are different, the water pressure, the temperature and the water spraying position sprayed from the gynecological washing nozzle and the intestinal nozzle have larger difference, and the bad use feeling generated by the user is more obvious.

Referring to fig. 18, the second embodiment of the toilet bowl is a schematic view showing the movement state of the hole of the opening and closing member and the spout when the user selects the bowel cleansing function (i.e., the third function outlet sprays water). In fig. 18 a, after the toilet receives the instruction of the intestinal tract cleaning function, the first electric device and the second electric device drive the opening and closing member and the spout to move to the reset position, at this time, the first through hole 311 and the second through hole 312 are both closed, and the spout is not extended; referring to fig. 18 b, after the resetting is completed, the controller 40 controls the second electric device to drive the first through hole 311 to rotate to a position between the second water outlet hole 122 and the third water outlet hole 123, at this time, the second through hole 312 is communicated with the diversion trench, and the self-cleaning structure 20 washes the nozzle; referring to fig. 18 c, the second through hole 312 of the opening and closing member is maintained at the position of b in fig. 18, and the controller 40 controls the first electric device to rotate to drive the nozzle to extend; in fig. 18 d, the controller 40 determines that the nozzle extends to the command position, the second electric device drives the first through hole 311 of the opening and closing member to be communicated with the third water outlet hole 123, at this time, the second through hole 312 is closed, the first electric device stops moving, and the nozzle starts to spray from the intestinal tract spray hole for cleaning; when a command of stopping water spraying is received, see e in fig. 18, the controller controls the second electric device to drive the first through hole 311 to rotate to a position between the second water outlet hole 122 and the third water outlet hole 123, at this time, the second water outlet hole 312 is communicated with the diversion trench, the first electric device rotates to drive the spray pipe to withdraw, and the recovered spray pipe is cleaned; when the nozzle is reset, the controller controls the axial bore to rotate back to the reset state, see f in fig. 18.

The utility model discloses the working procedure of toilet bowl, after the toilet bowl received the instruction that the user pressed the third function delivery port water spray that remote control or button sent, this toilet bowl opens and shuts the through-hole earlier remove to communicate with the guiding gutter, self-cleaning structure washs the nozzle, then the spray tube stretches out from the position that resets, and self-cleaning structure washs the spray tube. When the spray pipe extends to the designated position, the second electric device drives the through hole of the opening and closing piece to be switched to the position communicated with the second outlet hole from the position communicated with the diversion trench, and the through hole does not need to penetrate through other water outlet holes in the switching process, so that the problem that the flushing assembly sprays water to a human body discontinuously and sprays and washes sudden changes from different positions with different water pressures is avoided, and the use comfort of the toilet is improved. And the working step can clean the nozzle and the spray pipe before and after cleaning the human body, thereby reducing the accumulation of stains on the nozzle and the spray pipe and improving the cleanliness of the toilet bowl.

In this specification, the upstream direction is the forward direction and the downstream direction is the backward direction in the water flow in and out flow direction.

The present invention is not limited to the above embodiment, and if various modifications or variations of the present invention do not depart from the spirit and scope of the present invention, they are intended to be covered if they fall within the scope of the claims and the equivalent technology of the present invention.
