Patent Description:
Most of frame structures in the related art are one-piece, which guarantees stability of the frames. When mounting a component with a large size, the frame itself may block the mounting of the component, and thus the component is hard to be assembled into the frame. As to this problem, the related art discloses a frame structure, which includes a base and a vertical beam located at a front side of the base and extending upwards above a drying tub. When assembled to the drying tub, a rear side of the base is provided with no vertical beam. Thus, during assembly, the vertical beam located at the front side cannot provide good fixing for the drying tub, and it is easy to shake, to affect assembly effect.

A plurality of vertical beams are provided, and at least part of the vertical beams is formed by detachably connecting at least two sub-units.

In the support frame <NUM>, at least part of the vertical beams is formed by detachably connecting at least two sub-units. Thus, after the two sub-units are separated, an unobstructed large mounting space is defined, facilitating mounting of components. For example, if the support frame <NUM> is applied in the laundry processing device <NUM>, a large mounting space for mounting a laundry processing module can be defined by the support frame <NUM> after the sub-units of the vertical beam are separated. After completion of mounting the laundry processing module, the remaining sub-units are assembled, facilitating assembly. Furthermore, compared to a support frame <NUM> in the related art, the present embodiment further enhances strength of the support frame <NUM> without affecting mounting of components.

The base <NUM> is formed into a square base <NUM>. Four vertical beams are provided, i.e. a first vertical beam <NUM>, a second vertical beam <NUM>, a third vertical beam <NUM> and a fourth vertical beam <NUM>. The four vertical beams are formed to extend upwards from four corners of the square base <NUM>, such that the four vertical beams are utilized to define an accommodating space between them.

Two corners located at a side of the square base <NUM> are provided with the first vertical beam <NUM> and the second vertical beam <NUM> respectively, and the first vertical beam <NUM> and/or the second vertical beam <NUM> are formed by detachably connecting at least two sub-units.

According to an optional embodiment of the present application, the first vertical beam <NUM> is formed by detachably connecting two sub-units. The two sub-units of the first vertical beam <NUM> are a first lower vertical beam <NUM> and a first upper vertical beam <NUM> respectively. The first lower vertical beam <NUM> extends upwards from the square base <NUM>, the first upper vertical beam <NUM> extends upwards from the first lower vertical beam <NUM>, and the first upper vertical beam <NUM> has a lower end detachably connected to an upper end of the first lower vertical beam <NUM>.

Specifically, as illustrated in <FIG>, the vertical beams include two short vertical beams and three long vertical beams. The two short vertical beams and the three long vertical beams all extend in an up-and-down direction. Lower ends of one short vertical beam and the three long vertical beams are connected to four corners of the square base <NUM> respectively, and the short vertical beam and lower portions of the three long vertical beams are utilized to define a first accommodating space <NUM> located at a lower portion. The short vertical beam has a small height, thus it will not has an interference effect during mounting upper components. That is, a large mounting space is defined between the fourth vertical beam <NUM> and the second vertical beam <NUM>, and upper components can be easily assembled into a second accommodating space <NUM> through the mounting space. After assembly of the component is completed, the lower end of the second short vertical beam is connected to the upper end of the first short vertical beam, greatly improving assembly efficiency and structural stability.

According to another optional embodiment of the present application, the second vertical beam <NUM> is formed by detachably connecting two sub-units. The two sub-units of the second vertical beam <NUM> are a second lower vertical beam <NUM> extending upwards from the square base <NUM> and a second upper vertical beam <NUM> extending upwards from the second lower vertical beam <NUM>, respectively. A lower end of the second upper vertical beam <NUM> is detachably connected to an upper end of the second lower vertical beam <NUM>.

Specifically, as illustrated in <FIG>, the vertical beams include four short vertical beams and two long vertical beams. The four short vertical beams and the two long vertical beams all extend in the up-and-down direction. Lower ends of two short vertical beams and the two long vertical beams are connected to the four corners of the square base <NUM>, such that the two short vertical beams and lower portions of the two long vertical beams define a first accommodating space <NUM> located at a lower portion. When first upper vertical beam is separated from the first lower vertical beam, and the second upper vertical beam is separated from the second lower vertical beam, a large mounting space is defined in an upper portion of the frame. That is, a wide range of mounting space is defined behind the third vertical beam and the fourth vertical beam, and a laundry processing module can be conveniently passed through the mounting space and assembled into the support frame <NUM>. After completion of assembly of the component, the lower ends of the two short vertical beams are connected to the upper ends of the two short vertical beams, greatly improving assembly efficiency and structural stability. Thus, the present embodiment can make the laundry processing module be assembled into the second accommodating space <NUM> more conveniently.

In some examples, the lower end of the first upper vertical beam <NUM> is provided with a vertical beam connecting sheet <NUM> extending downwards, and the vertical beam connecting sheet <NUM> of the first upper vertical beam <NUM> is connected to the upper end of the first lower vertical beam <NUM> by a fastener. The lower end of the second upper vertical beam <NUM> is provided with a vertical beam connecting sheet <NUM> extending downwards, and the vertical beam connecting sheet <NUM> of the second upper vertical beam <NUM> is connected to the upper end of the second lower vertical beam <NUM> by a fastener. For example, the vertical beam connecting sheet <NUM> defines a perforation adapted for passage of the fastener, facilitating connection.

In some examples, the vertical beam connecting sheet <NUM> of the first upper vertical beam <NUM> is bent outwards and extends downwards relative to the first upper vertical beam <NUM>, such that at least part of an outer side of the upper end of the first lower vertical beam <NUM> is covered by the vertical beam connecting sheet <NUM>. The vertical beam connecting sheet <NUM> of the second upper vertical beam <NUM> is bent outwards and extends downwards relative to the second upper vertical beam <NUM>, such that at least part of an outer side of the upper end of the second lower vertical beam <NUM> is covered by the vertical beam connecting sheet <NUM>. This not only facilitates the connection, but also ensures the connection reliability and stability between them.

According to an embodiment of the present application, the square base <NUM> has a bottom plate <NUM> and four side enclosure plates <NUM> connected to sides of the bottom plate <NUM>. Lower ends of two adjacent vertical beams are connected by the side enclosure plate <NUM>, to ensure connection reliability and structural stability of the support frame <NUM>.

According to an embodiment of the present application, the support frame <NUM> further includes a plurality of connecting cross beams <NUM>. Middle portions of two adjacent vertical beams are connected by the connecting cross beam <NUM>, to further ensure connection reliability and structural stability of the support frame <NUM>.

In some embodiments, two corners located at another side of the square base <NUM> are provided with a third vertical beam <NUM> and a fourth vertical beam <NUM> respectively. Middle portions of outer surfaces of the third vertical beam <NUM> and the fourth vertical beam <NUM> each define a recessed first accommodating recess <NUM>, and two ends of at least one connecting cross beam <NUM> are disposed in the first accommodating recesses <NUM> of the third vertical beam <NUM> and the fourth vertical beam <NUM>, respectively, to prevent the connecting cross beam <NUM> from occupying excessive space and also to achieve positioning and mounting, which facilitates improvement of assembly efficiency of the support frame <NUM>. Meanwhile, the design of the first accommodating recess <NUM> also enhances strength of the vertical beam, and reduces its deformation and damage.

In some examples, a bottom wall of the first accommodating recess <NUM> defines a snapping hole <NUM>, and two ends of the connecting cross beam <NUM> are each provided with a snapping tongue <NUM>. The snapping tongue <NUM> is bent towards the vertical beam (bent rearwards as illustrated in <FIG> and <FIG>), and the snapping tongue <NUM> is inserted downwards into the snapping hole <NUM>, to mount the connecting cross beam <NUM> to the third vertical beam <NUM> and the fourth vertical beam <NUM>. In some specific examples, the snapping tongue <NUM> may have a hook shape, to hang the connecting cross beam <NUM> on the two vertical beams.

The support frame <NUM> further includes a top connecting frame <NUM>. The top connecting frame <NUM> is connected to the upper end of the vertical beam. At least part of the top connecting frame <NUM> is integrally formed with one sub-unit of the vertical beam from the same plate using a bending forming process.

Referring to <FIG> and <FIG>, the top connecting frame <NUM> is connected to the upper end of each of the first upper vertical beam <NUM>, the second upper vertical beam <NUM>, the third vertical beam <NUM> and the fourth vertical beam <NUM>.

It could be understood that, the at least part of the top connecting frame <NUM> is formed by bending one sub-unit of the first vertical beam <NUM> and/or the second vertical beam <NUM>.

Specifically, in an example illustrated in <FIG>, a cross beam of the top connecting frame <NUM> extending in a front-and-rear direction is integrally formed with the first upper vertical beam <NUM> from the same plate by using a bending forming process. Before the first upper vertical beam <NUM> is connected to the first lower vertical beam <NUM>, a mounting space having a large opening is defined by upper portions of the third vertical beam <NUM>, the fourth vertical beam <NUM> and the second vertical beam <NUM>, such that a component to be assembled can be conveniently mounted in the second accommodating space <NUM>. After completion of assembly, the first upper vertical beam <NUM> which is connected with the top connecting frame <NUM> is connected to the first lower vertical beam <NUM>. The operation is simple, facilitating improvement of the assembly efficiency.

In an example illustrated in <FIG>, a cross beams of the top connecting frame <NUM> extending in the front-and-rear direction and located at a right side is integrally formed with the first upper vertical beam <NUM> from the same plate by using a bending forming process, and a cross beam of the top connecting frame <NUM> extending in the front-and-rear direction and located at a left side is integrally formed with the second upper vertical beam <NUM> from the same plate by using a bending forming process. Before the first upper vertical beam <NUM> is connected to the first lower vertical beam <NUM> and the second upper vertical beam <NUM> is connected to the second lower vertical beam <NUM>, only the third vertical beam <NUM>, the fourth vertical beam <NUM> and the four connecting cross beams <NUM> are relied on to provide support for the component to be assembled. As this is not a closed structure and will not interfere with or block the component to be assembled during assembly, the mounting of the component to be assembled is further facilitated. After completion of assembly, the first upper vertical beam <NUM> and the second upper vertical beam <NUM>, which are connected with the top connecting frame <NUM>, are connected to the first lower vertical beam <NUM> and the second lower vertical beam <NUM>, respectively. The operation is simple, facilitating improvement of assembly efficiency.

The corner of the top connecting frame <NUM> located at the front right is snap-fitted with the upper end of the fourth vertical beam <NUM> through fit between the insertion sheet <NUM> and the notch <NUM>. Furthermore, the upper end of the third vertical beam <NUM> is also snap-fitted with the corner of the top connecting frame <NUM> located at the front left through fit between the insertion sheet <NUM> and the notch <NUM>. The connection is reliable and stable.
