The specific embodiment
The invention will be further described below in conjunction with drawings and the specific embodiments:
As shown in Figure 1 and Figure 2, bathing waste water filtering and draining device includes ponding dish 1, overflow formula strainer 3 and reversal valve 2 between the ponding dish and spent hot water's retracting device of bath wastewater draining.Wherein:
The waste water import 211 of body can communicate with the retracting device import 222 of outer sleeve body by delivery port 213 for the passway that the spent hot water after filtering through strainer 3 enters interior body 21 in described; This waste water import 211 is common cavernous structure, and profile can be circle, also can be square, or the circular and square shape that combines.The passway of the flushing water import 212 of body interior body 21 for the recoil water of washing and filtering device 3 enters can communicate with the sewage draining exit 223 of outer sleeve body 22 by delivery port 213 in described.The delivery port 213 of body is and the retracting device import 222 of outer sleeve body 22, the planform that sewage draining exit 223 matches in described, by interior body 21 relatively rotating in outer sleeve body 22, this delivery port 213 communicates with retracting device import 222, sewage draining exit 223 respectively, forms the spent hot water and flows to the passage that retracting device or backwashing water flow to sewer.The switch groove 214 of body is the localization part of mechanical knob switch on interior body 21 in described, the manufacturing that can match with the mechanical knob switch of its structure, shape.The dowel hole 215 of body can manufacture when outer sleeve body 22 assembles with interior body 21 in described, by the alignment pin in this dowel hole 215, can realize the location of angle when interior body 21 rotates, and guarantees the convenient and reliable operation of mechanical knob switch.The step 216 of body is the draw bail between interior body 21 and the strainer 3 in described, can being connected and fixed by body in the realizations such as attachment bolt 21 and strainer 3.
The top of outer sleeve body 22 is located in the flushing water import 221 of described outer sleeve body, the manufacturing that matches with the flushing water import 212 of interior body 21 of its contour structures, and, when this flushing water import 221 communicates with the flushing water import 212 of interior body 21, the backwashing sewage water passage of back-flushing filter 3 can be formed, thereby backwashing sewage water sewer can be entered.The retracting device import 222 of described outer sleeve body and sewage draining exit 223 are respectively spent hot water after the filtration and enter the passway that retracting device and flushing water enter sewer, and this retracting device import 222 and sewage draining exit 223 symmetry manufacturing respectively are 180 ° of straight line rightabouts.By the rotation of interior body 21, can make the spent hot water flow to retracting device or flushing water is entered sewer.The locating slot 224 of described outer sleeve body is diametric two semi-circular groove, the stopping means that rotates in outer sleeve body 22 for interior body 21; The angle that interior body 21 rotates with respect to the limit of outer sleeve body 22 is 0 ° and 180 °, by the position-limiting action of locating slot 224, can realize communicating and closing of each hole between the inside and outside body easily and accurately.
Working method 2 of the present invention, for body 21 in of the present invention turns over working method after 180 °, as shown in Figure 2, flushing water import 212 in the interior body 21 is in communicating state with the flushing water import 221 in the outer sleeve body 22, and the delivery port 213 in the interior body 21 also is in communicating state simultaneously with the sewage draining exit 223 in the outer sleeve body 22.Under this duty, putting flushing water above strainer 3 filter screens 32 recoils to strainer 3, the backwashing sewage water that washing and filtering device 3 forms is body 21 in the flushing water import 221 of outer sleeve body 22 and the flushing water import 212 in the interior body 21 enter into, and then enters sewer through the passage of sewage draining exit 223 formation in the delivery port 213 of interior body 21 and the outer sleeve body 22.
The interior body by handling reversal valve and the relative rotation of outer sleeve body, described filtering and draining device can switch between above-mentioned working method 1 and working method 2, makes this device have the function of filtered and recycled and sewage backwash two aspects.
Owing to adopt above technical scheme, the present invention matches with retracting device to use and has tangible advantage and good effect than existing simple retracting device.It not only can guarantee the cleaning of retracting device and unimpeded, and can fully guarantee the functional performance and the result of use of retracting device, can also prolong the application life of retracting device.Simultaneously, compact conformation of the present invention, easy to process, and also all connection places all adopt the connecting mode of screw thread or bolt etc., are convenient to dismounting and cleaning, are very suitable for using.
As optimal way of the present invention, retracting device is for reclaiming the heat interchanger of waste water residual heat.As the optional mode of another kind of the present invention, retracting device also can be to reclaim the water saving fixtures that waste water carries out cycling and reutilization.
(patent No.: the ZL00201305.3) use that matches, its result of use will be more obvious, effectively, can prolong the application life of heat interchanger better for the present invention and the applicant's patented product assembling screw shell heat interchanger.
