A mechanical timer and two double contact switches K1 and K2 on the mechanical timer are connected in series with a control circuit of an electric machine so as to form three power on loops; one path has the structure that the K1 directly is connected with the electric machine so as to form a dewatering power on loop; second path has the structure that the K1 is communicated with the K2 and two contacts of the K2 are respectively be connected with the electric machine in repeatedly contacting way so as to form the clockwise and anticlockwise rotary intermittence washing power on loop; thereby, the utility model has the advantages of simple structure, low cost, small size, light weight, multiple purposes in one machine, convenient maintenance, etc.

Description

Washer-extractor

The utility model relates to a kind of washing clothes also can be to its car washing installation that dewaters.

Existing Water Extraction Machinery is to drive dehydration barrel by dehydration electric motor to rotate at a high speed, produce bigger centrifugal force thus, a barrel interior clothing is attached on barrel wall, moisture content is then dished out at a high speed by the hole on the bucket wall, reach the purpose of sloughing moisture content on the clothing, but dehydration barrel only has only a dehydrating function.Existing washing machine mainly comprises single container washing machine and intelligentized automatic washing machine.Single container washing machine is that washing motor drives impeller and carries out positive and reverse return and transfer and realize washing function, and it does not have dehydrating function.Two-tub washing machine is made of the washtub of washing motor drive impeller rotation and the dehydration barrel that is driven by dehydration electric motor, and they realize washing clothes and dehydrating function respectively.Automatic washing machine is to adopt a motor to realize washing and dewater two kinds and move, but this motor must slow down to cooperate and drive impeller and wash action by clutch, and directly drives dehydration barrel with this motor and carry out clothes dewatering.In sum, washing machine or Water Extraction Machinery are except that other control assembly, the words of having only a motor, can only realize dewatering or wash in a kind of function, on the washing machine if having washing simultaneously and during dehydrating function, except other control assembly, must have two motors or a motor to add a clutch could realize.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, compact, with the motor washer-extractor of two processes that just can wash and dewater.

The purpose of this utility model is finished by following technical solution, it mainly comprises cylindrical shell, base, be installed in the motor in the base, braked wheel, the dehydration barrel in simplified and the cover plate on cylindrical shell top etc. are serially connected with two and cooperatively interact and form the contact switch K of three control power circuits with motor in the power circuit of control motor ₁And K ₂, this two can only put K switch ₁And K ₂Be arranged on the timer, and can put K switch by the timer drive ₁And K ₂Action is to finish the work that switches on and off power circuit.

Described contact switch K ₁And K ₂Be double contact switch, promptly they are made of two stationary contacts and a movable contact, wherein K ₁Stationary contact B be connected to motor formation-power circuit, K ₁Stationary contact A be connected to K ₂Movable contact, and K ₂Two stationary contact c, d be connected to motor respectively and form positive and negative separately two power circuits.

Above-mentioned two contact switch K ₁And K ₂Be set on the timer, and timer is positioned on the control panel on cylindrical shell top.

The utility model also is fixed with impeller in the bottom center of dehydration barrel.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an Electric Machine Control power circuit principle schematic of the present utility model.

Below by accompanying drawing the utility model is described in detail.The utility model adopts single barrel of formula of unit, it is made of top staving 1 and bottom base 2, in base 2, motor 4 is installed by damping spring 3, on the axle of motor 4 braked wheel 5 is housed, motor shaft upwards stretches into cylindrical shell 1, be provided with leather cup support 6 in the junction of stretching into cylindrical shell 1, device has had the leather cup 7 that sealing and flexible support are used on it, it is being inserted in motor shaft and is being fastened on the leather cup support 6, and motor shaft on stretching into the bottom that its end, cylindrical shell 1 back is connected in the dehydration tube 8 that is placed in cylindrical shell 1 in bottom the dehydration tube on, central authorities are fixed with impeller 13, thus can be directly rotation by motor 4 drive dehydration barrel 8 rotations.Offer through hole 9 on the perisporium of dehydration barrel 8, dehydration barrel 8 is when dewatering action, and water will leak from above-mentioned through hole 9.Reach dehydrating effect.Top at cylindrical shell 1 is connecting the cover plate 10 that can upwards dig with articulated structure, and the limit of cover plate 10 is provided with control panel 11, and timer 12 is installed on the plate.

The utility model adopts unit monotubular formula structure, and it mainly makes the motor can be by washing, dehydration necessary requirement and action respectively requires motor 4 can intermittently drive dehydration barrel 8 during as washing and carries out low speed rotating campaign by motor control loop.And when dehydration, require motor 4 to rotate at a high speed.For reaching above-mentioned goal of the invention, the utility model adopts mechanical timer (clockwork spring type) G, and timer is provided with two double contact switch K ₁And K ₂, i.e. this two double contact switch K ₁And K ₂Constitute by a movable contact and two stationary contacts respectively, and described movable contact is attached on mechanical timer G and the turning cylinder, two stationary contacts are placed on the corresponding position, the rotation of the turning cylinder by timer, be switched on or switched off action respectively in order, its course of action is: above-mentioned two double contact switch K ₁And K ₂Be serially connected in the control circuit of motor 4 K respectively ₁Stationary contact A be connected in motor M and constitute a dehydration power circuit.K ₁Stationary contact B be connected in K ₂Movable contact, and K ₂Two stationary contact c, d be connected to respectively on the binding post of motor M, constitute positive and negative two power circuits respectively, and be connected to a capacitor C between them.During use, the turn-knob of timer G is gone to washing location A, timer G work this moment, make contact K switch ₂Then remain intermittent connectivity action between two stationary contact c, d, at this moment motor M drives dehydration barrel and turns left or turn right motion under lower-speed state.When the turn-knob of timer G goes to dehydration location automatically, this moment contact switch K ₁To directly connect stationary contact B, at this moment K ₂Contact switch still keeps movable contact intermittently to contact respectively with two stationary contact c, d under the effect of timer G, but no power, this moment is by contact switch K ₁Directly connect the dehydration power circuit of motor, motor M is rotated at a high speed carry out dehydration work.Timer described in the utility model also can be selected motor timer etc. for use.The utility model compared with prior art, have simple in structure, but the low reduced volume of cost is in light weight, a tractor serves several purposes, maintaining is convenient, is suitable for the actual characteristics such as promote the use of of Modern Family.
