Description

High-speed hanging dryer

Technical field

The invention provides a dewatering device, in particular to a high speed and low noise high speed hanging type dryer.

Background technique

Traditionally, clothes or other clothes need to be air-dried after washing. In the drying process, it is ideal to have the weather of the sun. However, in fact, various weathers such as cloudy and rainy days make the drying of traditional clothes very inconvenient. Moreover, the traditional drying method takes a long time, usually takes several days of drying time, and the ingredients of the soap or washing liquid remain in the clothes.

The household washing machine slowly walks into each household, and the washing machine usually has a dehydrating function, so that after the washed clothes are dehydrated, it takes only one day or so to dry. Some manufacturers have also introduced a dehydrator that only has a dehydrating function.

However, the problem with domestic washing machines and dryers is that the moisture cannot be sufficiently dried due to the low motor speed. For those who need to wear or use clothes immediately, household washing machines and dryers are not sufficient, but the drying time is reduced, and they cannot be worn or used immediately after dehydration.

Furthermore, at present, the household dryer mainly fixes a plurality of spring supports on the base, and the motor is connected from the lower side to the spring support member, and the upper end of the motor shaft is connected to the inner cylinder through the coupling shaft to realize the rotation and drying. However, the inner cylinder of the current dryer is easy to hit the outer tub, causing displacement and noise. Moreover, the rotation speed of the dryer is generally below 1500 rpm, and it is impossible to completely dry the clothes. If the clothes are to be fully dried, a higher rotation speed of 2000 rpm or more is required. If the existing household dryer is operated at a speed exceeding 1500 rpm, the dryer is prone to dumping and cannot work normally. .

In addition, other waterproof devices can be provided to protect the motor from being affected.

As shown in FIG. 7, the elastic member 9 may be a washer or a gasket, but a conventional gasket or gasket is easily broken due to a large shear force generated by high-speed rotation of the motor during use, and is preferably used in the present invention. A solid or hollow cylinder so that the shear forces generated during operation of the motor are offset by the rolling of the cylinder so that the elastomer does not tear. One end of the fixing member 8 is fixed to the motor, and the other end is fixed to the supporting plate through the radial direction of the elastic member 9.

In Fig. 8, the elastic member adopts a hollow cylindrical structure with a hollow passage 91 disposed therebetween.

In Fig. 9, the safety lock 12 adopts an electric circuit for calculating whether the outer cylinder cover 10 and the buckle 11 are engaged. Only when the outer cylinder cover 10 and the buckle 11 are covered, the motor can be operated to stop the brake, otherwise The brake 6 is operated to avoid danger and accident.

In Fig. 10, since the water is thrown out during operation of the dryer, it is easy to contact with the circuit structure. In order to ensure safety more effectively, the aforementioned safety lock structure may not be used, and a mechanical linkage structure is preferably used. The outer bucket cover 10 and the electric switch are controlled by mechanical linkage, the power source is connected to the motor and the brake through the junction box 20, and the power supply is turned on and off by the upper switch handle 21.

The rear end of the outer tub cover 10 is rotatably fixed on the dryer, and the front end of the outer tub cover 10 is provided with a lock nose for fastening to the dryer, and a switch handle 21 is disposed on the dryer for pressing the buckle The rear outer lid 10 is also used to start the dryer.

The lower end of the safety pin 24 is provided with a spring 25 for providing an upward force to the safety pin 24. A cover button 22 and a safety lock cylinder 23 connected thereto are also provided, and the safety pin 24, the cover button 22, and the safety lock cylinder 23 are located on the same side of the switch handle 21.

10 and 11, when the outer lid 10 is opened by pressing the lid open button 22, the safety pin 24 is protruded upward to prevent the switch handle 21 from being erroneously operated to start the machine.

When the power is turned on, the outer cylinder cover 10 is covered, and the safety pin 24 is pressed downward to move into the cylinder body, and then the rotary handle 21 is pressed against the outer cylinder cover 10, at which time the spin dryer can be started. An exemplary structure is such that when the outer cylinder cover 10 is closed, the lock nose of the outer cylinder cover 10 presses the spring of the safety pin 24 to sink it, thereby releasing the restriction on the switch handle 21; at the same time, the safety pin 24 sinks to the end. At this time, the restriction on the safety lock cylinder 23 is lost, and the safety lock cylinder 23 is automatically buckled into the lock nose of the outer cylinder cover 10 by the torsion spring, thereby forming the lock of the outer cylinder cover 10.

When the machine is turned off, turning the switch handle 21 to the OFF side, the machine is powered off, and the brake 6 is activated, at which time the outer cylinder cover 10 is still in the locked state. When the cover button 22 is pressed, the safety lock cylinder 23 rotates out of the outer cylinder cover 10 to lock the nose, and the safety lock cylinder 23 no longer presses the safety pin 24, and the safety pin 24 re-emerges under the action of the spring, and the outer cylinder cover 10 also Under the action of its elastic action and safety pin spring, it will pop up and the safety pin 24 will bounce upward under the action of the spring.

In the structural design, the distance between the bottom of the inner cylinder and the support plate is 15mm-20mm, which ensures that the inner cylinder 2 does not contact the support plate 3, and does not affect the rotation of the inner cylinder 2, but does not cause the discharge inside. The water from the barrel 2 is splashed onto the motor. The distance from the bottom of the brake to the support plate is set to A, the distance from the top of the inner cylinder to the support plate is set to B, and A is not less than 1/4 of B and not more than 3/4 of B.

The invention does not use the cup to seal the water at the bottom of the tube, thereby avoiding the vibration of the rotating shaft passing through the cup to the outer tube, thereby reducing the vibration during use. The inner cylinder of the present invention forms a symmetrical inverted triangular structure with the motor, so that the vibration range of the outer cylinder is very small. The motor is suspended by the shock absorber to the bottom of the support plate, which can automatically adjust the position of the center of gravity, can maintain the concentricity with the inner cylinder, has good dewatering effect, saves energy, and reduces working time.

By adopting the above settings, the high-speed suspension type dryer can smoothly achieve a high rotation speed of 2500 rpm or more, with lower noise, less jitter, high machine stability, and the drying of clothes minimizes drying. Time, even dry, can be worn, reducing people's drying time.
