Detailed description of the invention
With specific embodiment, the utility model is described further below.
Be illustrated in figure 1 the electronic toilet of a kind of low noise of the present utility model, it comprises water closet body (omit in figure and do not draw), seat ring 7, hydro-peening system 1, heating water tank 3, circulating water pump 5, supercharging impeller water pump 2, threeway backwater joint 6, first tee junction 10, second tee junction 9 etc.Described seat ring 7 has can the liquid storage cylinder of accommodating hot water, and seat ring liquid storage cylinder is provided with water inlet, the first water return outlet and the second water return outlet.
The device that heating water tank 3 heats as topmost water and stores, is provided with heater strip in it, casing is provided with heating water tank water inlet 303, heating water tank delivery port 301, heating water tank water return outlet 302, spilling water stack 304.Heating water tank water inlet is positioned at the bottom of casing.Water inlet is connected with running water pipe, and is provided with water intaking valve 8.Also be provided with water level switch 11 in casing, it can detect the water level of heating water tank, and when detecting that in case, liquid level is lower than the low liquid level of appointment, namely control circuit can control water intaking valve 8 and open, and starts water inlet; And after water level is higher than appointment low water stage, circulating water pump is started working; When detecting that in case, liquid level is higher than the high liquid level of appointment, namely control circuit can control water intaking valve 8 and cut out, and stops water inlet.
The delivery port 301 of heating water tank connects the water inlet 502 of circulating water pump 5.Circulating water pump delivery port 501 is access to seat ring liquid storage cylinder water inlet.
Described seat ring liquid storage cylinder has the water stream channel of annular, seat ring offers respectively the first water inlet 701, second water inlet 702, first water return outlet 703 and the second water return outlet 704.As Fig. 1, Fig. 7, Fig. 8 are visible, water inlet and the first water return outlet 703 lay respectively at the starting point of annular flow channel and terminal and separated by a longitudinal septum 705, and seat ring liquid storage cylinder second water return outlet 704 and seat ring liquid storage cylinder water inlet are located on the same side of longitudinal septum.Seat ring liquid storage cylinder second water return outlet 704 in the vertical direction is higher than seat ring liquid storage cylinder first water return outlet 703 and water inlet.Can first flow into from water inlet from the water of circulating water pump 5, flow in seat ring liquid storage cylinder one week could flow out from the first water return outlet 703 and through the first return pipe 723 flow out seat ring give impeller pump 2 pump chamber moisturizing and be back to heating water tank 3, inner air is then discharged outside seat ring liquid storage cylinder by the second water return outlet 704 and the second return pipe 724.Namely the second water return outlet 704 is double plays the backwater effect be vented and after seat ring liquid storage cylinder 7 full water.In this example, seat ring liquid storage cylinder is provided with the first water inlet 701 and the second water inlet 702, and circulating water pump delivery port 501 is connected by the first water inlet 701 of the second tee junction 9 and seat ring liquid storage cylinder and the second water inlet 702 water inlet.Certainly, also according to actual conditions, a seat ring liquid storage cylinder water inlet can be only set.
To be connected with water spray system 1 and what supply water to it is impeller pump 2.The delivery port 203 of impeller pump 2 is connected on the interface 101 of water spray system 1.
The water inlet of impeller pump 2 is connected with the first end of the first tee junction 10, and the second end of the first tee junction 10 is connected with the first return pipe 723, and the 3rd end of the first tee junction 10 is then connected with connecting 604.The first interface 601 of threeway backwater joint 6 is connected with connecting 604, second interface 602 of threeway backwater joint 6 is connected with seat ring second return pipe 724,3rd interface of threeway backwater joint 6 is then direct to be connected with heating water tank 302 water return outlet, and arranges flap valve 12 herein.Flap valve 12 is positioned at heating water tank 3, good seal performance, the aqueous reflux prevented in heating water tank 3.Impeller pump in the vertical direction, lower than circulating water pump water inlet 502, first flows through impeller pump to make the water coming from seat ring liquid storage cylinder and is filled by pump chamber, and then flow back to heating water tank 3 through connecting 604.Upper impeller pump 2 overcoat has damping gum cover 201, and is fixed on above warm air system 4 by screw.Gum cover 201 makes impeller pump 2 and realizes soft contact between main frame, can reduce vibrations when running.
Warm air system 4 is fixed on base, is in the side of water spray system.
Water inlet process of the present utility model is as follows: tap water enters heating water tank 3 from water intaking valve 8 through the bottom water inlet 303 of heating water tank 3.After water level rises to certain default liquid level, heating tube starts heating, circulating water pump 5 operates simultaneously, the water heated up a little is transported to seat ring liquid storage cylinder through seat ring water inlet pipe 721, and when water level in seat ring liquid storage cylinder rises to seat ring first water return outlet height, water can flow through impeller pump 2 by pump chamber priming petock through seat ring first return pipe 723, then arrives threeway backwater joint 6 and gets back to heating water tank 3.On the other hand, along with the water level in seat ring liquid storage cylinder rises, the air in seat ring liquid storage cylinder can be discharged to heating water tank 3 through the second return pipe 724, and when after seat ring liquid storage cylinder full water, water also can arrive threeway backwater joint 6 through the backflow of this pipe and enter heating water tank 3.Second return pipe 724 plays exhaust backwater effect, and the first return pipe then plays backwater effect.Heating water tank 3 middle water level is elevated to a certain degree, and water level switch will control water intaking valve 8 and close, and heating tube continues the water heating in heating heating water tank 3 and makes it circulate in the water route of whole system by circulating water pump 5, and last water termostat is at design temperature.
When user uses water spray system 1, water spray system is opened, impeller pump 2 is started working, drawn water from seat ring liquid storage cylinder by the first return pipe 723 and the second return pipe 724, first return pipe directly draws water supply impeller pump from seat ring liquid storage cylinder, and the second return pipe then flows to impeller pump through connecting, and water is sent through impeller pump 2 delivery port 203, water spray system is entered, finally from the functional hole ejection water spray system 1 shower nozzle from interface 101.When impeller pump 2 works, noise is very little, builds the comfortable environment that goes to toilet to user.According to the gear that user selects, electronic toilet can control the rotating speed of this pump, thus regulating pondage heel pressure.In the hydro-peening stage, when the water level switch of heating water tank detects low water stage, heating water tank can start intake and heat.
In order to make impeller pump can fill water in pump chamber when life's work, the utility model is provided with the self-cleaning operation of hydro-peening system.Namely when starting shooting first, after energising water inlet, water level beginning detects that the water level in heating water tank attains to a high place, meaning heating water tank and seat ring liquid storage cylinder reach peak level all, impeller pump can start work, the hydro-peening system of connection impeller pump is sprayed water, impeller pump, air between impeller pump and the switch of hydro-peening system shower nozzle are discharged, makes real being immersed in water of impeller pump.The self-cleaning operation duration was approximately for 6 ~ 8 seconds.
Above-described embodiment is only as one of preferred embodiment of the present utility model; not limit practical range of the present utility model with this; therefore all equivalence changes done according to shape of the present utility model, structure, principle, all should be covered by within protection domain of the present utility model.
