Background technique

Please refer to shown in Fig. 1, existing pulsator type washing machine comprises: the appearance casing 11 of washing machine; The inside of casing 11 is provided with and hangs and fixes by suspender spring device 12, and is used to hold the outer bucket 13 of washing water ; The rotatable washing tub 14 installed inside the outer tub 13 and coaxial with the outer tub 13; the lower side of the outer tub 13 and the inside of the washing tub 14 are provided with an agitator 15, and the above-mentioned outer tub 13, washing tub 14 and agitator 15 can be unified It is the outer barrel assembly A1. In the prior art, the outer tub assembly A1 is suspended on the housing 11 by means of the boom spring device 12, and the contact position between the boom spring device 12 and the outer tub assembly A1 is at the lower end of the outer tub assembly A1. The upper end of the assembly A1 is in a free state and tends to tilt in a certain direction, so that the center of gravity deviates from the dehydration rotation axis. When the washing tub 14 is washing and rotating, especially when the washing tub 14 is rotating at a high speed for dehydration, the vibration is large and the noise is also large, so it is easy to hit The casing 11 is easy to generate noise and even damage the machine; it hits the safety protection switch to make the washing machine refill the water to wash and adjust the distribution of clothes, which is easy to waste water and electricity resources and prolong the washing time.

Utility model content

The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a fully automatic washing machine in which the center of gravity deviates from the dehydration rotation axis and the outer tub assembly maintains a horizontal state by adding an elastic connection between the outer tub and the shell.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a vibration-reducing and noise-reducing washing machine includes a housing, an outer bucket is arranged in the housing, and a boom spring device is included, and one end of the boom spring device is connected to the On the housing, the other end is connected to the lower end of the outer tub, and at least four vibration-damping connectors are included. One end of the vibration-damping connectors is connected to the upper outer edge of the outer tub, and the other end is connected to the housing. One end of the connecting piece connected to the outer edge of the upper part of the outer barrel is evenly distributed on the outer edge of the outer barrel.

The vibration-damping connector is a spring.

The vibration-damping connector is arranged parallel to one of the walls of the casing.

The vibration-damping connector is arranged parallel to the horizontal plane. Adopting a structure arranged in parallel can achieve a better balance effect.

Compared with the prior art, the utility model has the following advantages: the vibration-absorbing connector can keep the outer tub assembly in a horizontal state, thus reducing the violent vibration of the outer tub and impacting the shell due to the uneven distribution of clothes in the washing tub. and safety protection switch, reduce vibration, reduce noise, and also reduce washing water and electricity consumption increased by touching the safety switch. The utility model adopts four vibration-damping connectors to make the outer tub assembly in a horizontal state, greatly The stability of the washing machine is improved, and the washing machine is a novel fully automatic washing machine with reasonable and simple structure and excellent performance.

Detailed ways

The content of the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Example:

Please refer to Fig. 2, a vibration-reducing and noise-reducing washing machine includes a housing 1, an outer tub 3 is arranged inside the housing 1, a washing tub 4 and an agitator 5 are coaxially arranged in the outer tub 3 in turn, and the outer tub 3 is Bucket 3, washing bucket 4 and agitator 5 constitute the outer tub assembly A, which includes a boom spring device 2, one end of the boom spring device 2 is connected to the four corners of the housing 1, and the other end is connected to the lower end of the outer tub 3 , also includes at least four damping connectors 6, one end of the damping connectors 6 is connected to the upper outer edge of the outer tub 3, the other end is connected to the four corners of the housing 1, and the vibration damping connectors 6 are connected to the outer tub 3 One end of the upper outer edge is evenly distributed on the outer edge of the outer bucket 3 .

The outer tub assembly A is suspended on the casing 1 by means of four suspender spring devices 2 hanging on the lower end of the outer tub 3 and leveling at least four damping connectors 6 .

The vibration-damping connector 6 of this embodiment adopts a spring structure, and there are four vibration-damping connecting springs in total.

In order to further ensure the balance effect, the vibration-damping connector 6 is arranged parallel to one of the walls of the housing 1 , or arranged parallel to the horizontal plane.

When the washing machine is in the no-load and non-working state, the outer tub assembly A maintains a horizontal state, and the four vibration-damping connection springs maintain a free length without the effect of force. During the washing process of the washing machine, the agitator 5 drives the clothes to rotate, due to the effect of inertia The outer tub assembly A will also rotate, and the damping connection spring will generate tension or elastic force to keep the outer tub assembly A in a horizontal state; during the dehydration stage of the washing machine, because the laundry is not evenly distributed in the washing tub 4, the outer tub The center of gravity of the assembly A deviates from the dehydration rotation axis, and the four vibration-damping connection springs will generate tension or elastic force to keep the outer tub assembly A in a horizontal state, which greatly reduces the impact on the outer tub assembly caused by the high-speed dehydration rotation of the washing tub 4. The vibration and noise of A, and at the same time avoid wasting the water and electricity resources that need to be refilled and washed to adjust the distribution of clothes and prolong the washing time due to the excessive vibration of the outer tub assembly A hitting the safety protection switch; The spring will generate pulling force or elastic force to avoid hitting the housing 1 due to the dehydration inertia of the outer tub assembly A.

In this embodiment, the number of vibration-reducing connecting springs can be six or eight, and they are arranged on the edge of the outer barrel 3 at the same distance, which can also play the role of balancing the outer barrel assembly A.

The above detailed description is a specific description of the feasible embodiment of the utility model. This embodiment is not used to limit the patent scope of the utility model. Any equivalent implementation or change that does not deviate from the utility model shall be included in this case within the scope of the patent.
