Description

Technical Field

[0001] The present invention relates to the field of clothing treatment equipment, and more particularly, to a box structure, a production method, and a clothing treatment equipment having such a structure. Background Art

[0002] Existing clothing treatment equipment mostly includes washing machines and dryers. Washing machines are generally divided into drum type and agitator type. Compared with agitator type clothing treatment equipment, the structure of drum type clothing treatment equipment is more delicate and compact. The body of the drum type washing machine is only half the volume of the body of the agitator type washing machine. It not only occupies less space, but also is safe and convenient to use. Preferably, the drum type washing machine can prevent clothes from tangling, wash more evenly, and has a much lower wear rate on clothes than the agitator type washing machine. It can also wash clothes such as cashmere, wool, and silk, achieving comprehensive washing. In addition, the drum type washing machine has newly developed functions such as three-dimensional flow pattern and anti-water overflow. It not only causes no wear on clothes, has a high washing degree, but also has a high water utilization rate, saving water resources. The drum type washing machine has been favored by more and more consumers, and most dryers are of the drum type.

[0003] The laundry method of the drum type clothing treatment equipment is designed by imitating the principle of a club hitting clothes. The drum is rotated by the mechanical work of the motor, and the clothes are continuously lifted and dropped in the drum, lifted and dropped again, doing repetitive movements. This inevitably leads to severe vibration of the machine body during the laundry process. In order to enable the drum type clothing treatment equipment to withstand the above severe vibration, existing drum type clothing treatment equipment mostly uses a metal box to improve the mechanical strength of the box. However, due to the large weight of the drum, a strengthening structure needs to be added to its side plate to improve the use safety of the equipment.

[0004] Currently, the side walls of the boxes of drum type clothing treatment equipment on the market mostly use U-shaped metal bending to form, and then reinforcing members are welded or riveted to the upper and lower parts of the side walls respectively to increase the mechanical strength of the box and install the bucket for storing washing water and the drum inside the box. To form the above structure, not only special bending equipment and reinforcing member molds need to be customized, but also corresponding welding or riveting production lines need to be equipped. The production method is relatively complex, with large input of manpower and material resources and low production efficiency, which reduces the market competitiveness of the product to a certain extent.

[0005] Therefore, for the boxes of current drum type clothing treatment equipment, further improvement is still needed.

[0006] In view of this, the present application is specifically proposed. Summary of the Invention

[0007] The problem solved by the present invention is that in the prior art, there are many side plate strengthening structure components in the drum type clothing treatment equipment, with large investment and low production efficiency.

[0008] To solve the above problems, the present invention provides a box structure, a production method and a laundry treatment device having this structure. The box structure includes a box body, which includes a left side plate, a back plate and a right side plate. The left side plate and the right side plate are connected to the back plate to form a structure surrounded by three sides with openings at the front, top and bottom. An upper sealing plate is provided at the top of the box body. The upper sealing plate is connected to the left side plate, the right side plate and the back plate and covers the upper opening of the three-sided surrounding structure.

[0009] Specifically, the upper sealing plate is an integrally formed sheet metal structure. The setting of the upper sealing plate can reduce the production steps when installing strengthening members on the box body, improve the production efficiency of the product. At the same time, the setting of covering the upper opening of the three-sided surrounding structure can effectively improve the waterproof level of the laundry treatment device and extend the service life of the laundry treatment device.

[0010] Further, upper flanges are provided at the tops of the left side plate, the back plate and the right side plate. The upper sealing plate is placed on the upper flanges and fixedly connected to the upper flanges.

[0011] Since the left side plate, the right side plate and the back plate are all relatively thin, setting the upper flanges helps the installation of the upper sealing plate.

[0012] Further, a front side connection part is provided on the front side of the upper sealing plate. Front flanges are respectively provided on the front sides of the left side plate and the right side plate. A positioning structure is provided between the front side connection part and the front flanges.

[0013] The setting of the positioning structure can realize the rapid positioning of the upper sealing plate, which helps to shorten the installation time of the upper sealing plate and improve the installation efficiency.

[0014] Further, the positioning structure includes a hook and a hole. The hook extends into the hole to complete the positioning.

[0015] Specifically, the hook is provided on the front side connection part, and the hole is provided on the front flange. Their positions can be interchanged.

[0016] Further, at least one control board connection part is also provided on the upper sealing plate.

[0017] There are two control board connection parts, which are convenient for the stable connection of the control board.

[0018] Further, at least one avoidance part is also provided on the upper sealing plate.

[0019] The avoidance hole is used for the installation and / or wiring of internal components of the laundry treatment device.

[0020] Further, the avoidance part includes at least one wiring avoidance hole.

[0021] After the upper sealing plate is installed, the grounding wire can be taken out through the wire routing avoidance hole and fixed on the upper sealing plate, saving the setting of the grounding piece and ensuring the reliable grounding of the laundry treatment device.

[0022] Furthermore, at least one strengthening structure is also provided on the upper sealing plate.

[0023] Specifically, the strengthening structure can be a groove and / or a boss. The boss can provide support for the top cover of the laundry treatment device and improve its pressure resistance. The groove can be provided with corresponding fixing structures to complete the fixing of other components while strengthening the strength of the upper sealing plate.

[0024] The present invention also discloses a method for manufacturing a box body structure for manufacturing the box body structure as described above, which is specifically carried out according to the following steps:

[0025] S1: Bend the box body into a structure surrounded by three sides with openings at the front, top and bottom through a box body forming device;

[0026] S2: Set the upper sealing plate on the upper opening of the box body and position it through a positioning structure;

[0027] S3: Fix the upper sealing plate to the left side plate, right side plate and back plate to complete the production.

[0028] This manufacturing method uses a box body forming device and an upper sealing plate forming device. The entire manufacturing process can be completed with two sets of molds and the above three steps, which is convenient and fast. Correspondingly, in the prior art, at least two devices and four sets of molds are required to manufacture the box body, left strengthening member, right strengthening member and upper connecting plate. In the manufacturing steps, the left strengthening member, right strengthening member and upper connecting plate need to be positioned and fixed respectively, the manufacturing steps are cumbersome, the manufacturing efficiency is low, and the investment is large.

[0029] The present invention also discloses a laundry treatment device including the box body structure as described above.

[0030] The laundry treatment device has the same advantages as the above box body structure compared with the prior art, which will not be elaborated here.

[0031] Compared with the prior art, the box body structure of the present invention has the following advantages: Through the setting of the upper sealing plate, the present invention realizes the rapid installation of the side plate strengthening structure of the drum-type laundry treatment device, simplifies the composition of the strengthening structure at the same time, uses the fully covered upper sealing plate to fixedly connect the left and right side plates and the back plate, obtains a better strengthening effect, has a higher waterproof level at the same time, saves the corresponding equipment investment and mold investment, greatly reduces the production cost while improving the production efficiency.
