Description
Technical field
The present invention relates to washing machine structure, specifically refer to a kind of dewatering protector for washing machine.
Background technology
The machinery automatic washing machine is that door closure switch, drainage selector switch, not draining halt switch, water storage switch, rinsing selector switch, washing selector switch and dehydration switch etc. are formed by electric program-controlled device, water level switch, safety switch usually.By the control circuit that various switches are formed, control the voltage output of motor, water intaking valve, electromagnet to discharge water and buzzer, make washing machine realize program run.Carry out draining, dehydration procedure after the single wash operation finishes, and dehydration procedure carries out after generally needing to drain only in the drainage procedure end, with the water in the clothing bucket, dehydration procedure could carry out smoothly like this; Otherwise the laundry water in the clothing bucket does not also drain and just begins dehydration only, and not only dehydrating amount is big, wastes energy, and the stall phenomenon can take place, and washing machine can not be dewatered smoothly.Do not see in the existing automatic washing machine relevant apparatus that detects clothing inner bucket water amount before dehydration procedure is arranged.
Summary of the invention
Technical problem to be solved by this invention is that the present situation at prior art provides a kind of dewatering protector for washing machine that can detect the remaining water yield in the clothing bucket inner bag before dehydration procedure; so that washing machine just can carry out dehydration procedure under not with the situation of water as far as possible, reach the purpose of protection washing machine, using water wisely, energy savings.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of dewatering protector for washing machine; it comprises casing and dehydration barrel; it is characterized in that: other has pressure sensor device to be arranged on chassis cavity bottom and close chassis cavity bottom surface; and an end that makes pressure sensor device extends outside the chassis cavity bottom surface hermetically, and with control dehydration work whether microswitch contact conflicting cooperates.
As improvement, described chassis cavity bottom is provided with the groove that is used for collecting residual water, and pressure sensor device is arranged in the groove or groove and upwardly extending space, is convenient to further collect remaining water, and improves device work effect.
One of preferred, described pressure sensor device is to adopt flexure strip, is provided with the hole on the bottom surface of groove, flexure strip is arranged on this place, hole site hermetically, described shell fragment has and protrudes can conflict protuberance on described microswitch of this flexure strip, and is simple in structure, with low cost.
Preferred two, described pressure sensor device is to adopt floating block or ball float, and connects floating block or ball float and the connecting rod on described microswitch of extending, conflict downwards.
Further improve, described connecting rod comprises mutually the connecting rod first and the connecting rod second portion of bending at an angle, and described floating block or ball float are arranged on the end of described connecting rod second portion, and the connecting rod second portion passes hole on the bottom surface of groove.
At last, described microswitch is screwed on the chassis cavity reverse side.
Compared with prior art, the invention has the advantages that: by being provided with the control device of dehydration microswitch, can detect water remaining in the washing machine, control the keying of dehydration switch then according to detection architecture, thereby whether the control washing machine carries out dehydration procedure, avoided in washing machine water not drain that washing machine promptly starts the dehydration stall phenomenon that switch took place voluntarily according to predefined Mechanically programm under the clean situation, reduced dehydrating amount, the energy and water source have been saved, structure is very simple, with low cost, result of use is good.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, this dewatering protector for washing machine comprises:
The microswitch 3 of dehydration control, microswitch 3 in the present embodiment is arranged between the below and washing machine shell (not shown) of inner bag 1, be screwed on chassis cavity 1 reverse side, on the contact of the microswitch 3 of the protuberance 211 aligning dehydration controls of flexure strip.
As shown in Figure 1, behind washing machine drainage, if draining does not fully have remaining unnecessary sewage in the washing machine inner chamber, flexure strip 21 does not stress, be in to the curved naturally protruding state in 12 tops, hole, at this moment, the protuberance 211 of flexure strip does not contact microswitch 3, and microswitch 3 is in closure state, under the control of this predefined Mechanically programm of washing machine, close automatically logical, the beginning dehydration procedure.
As shown in Figure 2, sewage in the washing machine inner chamber not discharging is complete, at this moment, sewage can accumulate in the groove 11 of inner chamber, after flexure strip 21 is subjected to these pressure that accumulate in the sewage in the groove 11, and can be towards the direction bending of dehydration microswitch 3, thereby make protuberance 211 on the shell fragment 21 microswitch 3 of conflicting, disconnect the microswitch 3 of dehydration control by force, this moment, microswitch 3 was in off-state, made washing machine can not carry out dehydration procedure.This moment, washing machine can be reported to the police or other operation according to the program of design in advance.Effectively avoided in the washing machine inner chamber, remaining under the situation of sewage and carried out the caused stall phenomenon of dehydration procedure.
To shown in Figure 5, this dewatering protector for washing machine comprises as Fig. 3
The microswitch 3 of dehydration control, the microswitch 3 in the present embodiment is arranged between the below and washing machine shell (not shown) of inner chamber 1;
Water flotation gear 5, the water flotation gear 5 in the present embodiment comprises connecting rod 51 and floating block 52.Wherein, connecting rod 51 comprises mutually the connecting rod first 511 and the connecting rod second portion 512 of bending at an angle, the below that hole 12 is positioned at inner chamber 1 is passed corresponding to microswitch 3 by connecting rod first 511, connecting rod second portion 52 is positioned at the top of inner chamber 1, connecting rod first 511 adopts sealing rings, thereby is arranged on 12 places, hole hermetically and can be along the hole 12 rotates; Floating block 52 is fixed on the end of connecting rod second portion 512.Connecting rod 51 can move up and down in the hole, drive lower edge 12 of floating block 52, cooperates with microswitch 3.
As shown in Figure 3, behind washing machine drainage, if draining fully, do not have remaining unnecessary sewage in the washing machine inner chamber 1, floating block 52 does not stress, and the microswitch 3 of dehydration control is left in the lower end of floating block 52, at this moment, microswitch 3 is in closure state, under the control of the predefined Mechanically programm of washing machine, close automatically logical, the beginning dehydration procedure.
As shown in Figure 4, when the sewage in the washing machine inner chamber 1 not discharging also have fully when remaining, at this moment, sewage can accumulate in the groove 11 of inner chamber 1, and floating block 52 is subjected to these buoyancy that accumulates in the sewage in the groove 11 come-ups, moves on the drivening rod second portion 512, thereby connecting rod first 511 is moved up, can not touch the contact of microswitch 3, disconnect microswitch 3 by force, make washing machine can not carry out dehydration procedure.This moment, washing machine can be reported to the police or other operation according to the program of design in advance.Effectively avoided in the washing machine inner bag, remaining under the situation of sewage and carried out the caused stall phenomenon of dehydration procedure.
