Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, and specifically relates to a washing machine with a split countertop module. Background Technology

[0002] The glass countertop of current drum washing machines is made by bonding the countertop frame and the glass with double-sided tape or solid adhesive. However, this method introduces several problems: 1. The gap between the glass and the countertop frame. If it's too small, the countertop frame may shrink and crush the glass in low temperatures; if it's too large, it will affect the appearance and may even allow foreign objects to fall in. 2. Since the glass is fixed to the countertop with double-sided tape or solid adhesive, the countertop frame's shrinkage in cold weather, pulling the glass through the adhesive, can also cause the glass to break (in extremely cold climates like those in Russia). 3. Water easily accumulates on the countertop and seeps into the gap between the glass and the countertop, causing mold to grow on the adhesive. 4. The back of the glass has a colored screen-printed finish; using solid adhesive or countertop adhesive can cause the screen-printed layer on the back of the glass to detach or peel off under large temperature differences.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention proposes a washing machine with a split countertop module, which facilitates the assembly and coordination between components, effectively protects the countertop glass, and improves product quality.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

The upper frame and the lower frame are fixed by fasteners, and a buffer strip is provided between the upper frame and the tabletop glass and / or between the lower frame and the tabletop glass.

[0010] Furthermore, the buffer strip has a first buffer bar located between the upper frame and the tabletop glass.

[0011] Furthermore, the upper frame has an upper frame body and an outer frame extending downward along the edge of the upper frame body, and the upper frame body is provided with a receiving groove for accommodating the first buffer strip.

[0012] Furthermore, multiple drainage grooves are provided on the side of the first buffer strip near the tabletop glass, allowing water to pass through.

[0013] Furthermore, multiple seepage channels are spaced apart.

[0014] Furthermore, the lower shell has a lower housing, a first mounting frame extending upward along the lower housing and surrounding the outside of the tabletop glass, and the buffer strip has a second buffer strip located between the first mounting frame and the tabletop glass.

[0015] Furthermore, the first buffer bar and the second buffer bar are arranged adjacent to each other.

[0016] Furthermore, the lower housing is provided with a flow guide groove located inside the first mounting frame, and a through flow guide hole is provided at the bottom of the flow guide groove.

[0017] Furthermore, the second buffer strip is located above the flow guide groove.

[0018] Furthermore, a plurality of spaced protrusions are provided on the side of the second buffer strip near the tabletop glass, and a drainage section for water to pass through is formed between two adjacent protrusions.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] See Figures 1-8 The figure shows the first embodiment of the washing machine with a split countertop module proposed in this invention. A washing machine with a split countertop module includes: a cabinet (not shown in the figure) and a split countertop module 100. The split countertop module 100 is provided on the top of the cabinet. The split countertop module 100 has: an upper frame 10, a lower shell 20, and a countertop glass 30 clamped between the upper frame 10 and the lower shell 20. The upper frame 10 and the lower shell 20 are fixed by fasteners 1. The countertop glass 30 is clamped between the upper frame 10 and the lower shell 20. Buffer strips 60 are provided between the upper frame 10 and the countertop glass 30, and between the lower frame 20 and the countertop glass 30. The split-type tabletop module 100 has an upper frame 10 and a lower shell 20. The tabletop glass 30 is clamped between the upper frame 10 and the lower shell 20. The upper frame 10 and the lower shell 20 are fixed by fasteners 1, which helps to ensure the firmness of the split-type tabletop module 100 after fixing and avoids the problem of gaps between components. By clamping the tabletop glass 30 and setting the buffer strip 60, when the shrinkage or expansion rate between the components is different due to temperature changes, it can be achieved by slight relative displacement between the tabletop glass 30 and the upper frame 10 and the lower shell 20, avoiding stretching of the tabletop glass 30, which helps to improve the quality of the product and expand the range of usable environments of the product.

[0052] In other implementations, a buffer strip 60 may be provided only between the upper frame 10 and the tabletop glass 30, or only between the lower frame 20 and the tabletop glass 30.

[0053] See Figure 6As shown, the buffer strip 60 has a first buffer strip 61 located between the upper frame 10 and the tabletop glass 30, and a second buffer strip 62 located between the lower shell 20 and the tabletop glass 30. The first buffer strip 61 is located above the tabletop glass 30, and the second buffer strip 62 is located on the outer side of the tabletop glass 30. The upper frame 10 and the lower shell 20 are injection molded using the same material, so the dimensional changes of the upper frame 10 and the lower shell 20 are the same when the temperature changes. When the temperature changes significantly, the dimensional change of the upper frame 10 and the lower shell 20 is greater than that of the tabletop glass 30. At lower temperatures, the shrinkage of the upper frame 10 and the lower shell 20 is greater than that of the tabletop glass 30. The tabletop glass 30 moves slightly relative to the upper frame 10 and the lower shell 20, causing both the first buffer strip 61 and the second buffer strip 62 to be slightly compressed.

[0054] See Figure 4 and Figure 6 As shown, the upper frame 10 is frame-shaped, comprising an upper frame body 11 and an outer frame 12 extending downwards along the edge of the upper frame body 11. A receiving groove 13 for accommodating the first buffer strip 61 is provided on the upper frame body 11, located on the lower end surface of the upper frame body 11. The first buffer strip 61 is horizontally positioned, and multiple drainage grooves 611 are provided on the side of the first buffer strip 61 near the tabletop glass 30, allowing water to flow through. These drainage grooves 611 allow water dripping onto the tabletop glass 30 to flow outwards, preventing water accumulation on the tabletop glass 30. The multiple drainage grooves 611 are spaced apart, creating a concave-convex shape on the side of the first buffer strip 61 near the tabletop glass 30. This facilitates the compression and deformation of the upper frame 10, preventing the shrinkage force caused by temperature changes from acting on the tabletop glass 30 and ensuring the safety of the tabletop glass.

[0055] See Figure 3 and Figure 4 As shown, the lower shell 20 has a lower shell 21 and a first mounting frame 22 extending upward along the lower shell 21. The first mounting frame 22 surrounds the outer side of the tabletop glass 30. The lower shell 21 is plate-shaped. The first mounting frame 22 and the lower shell 21 surround to form a rear receiving groove 23, in which the tabletop glass 30 is located. A second buffer strip 62 is located between the first mounting frame 22 and the tabletop glass 30. The second buffer strip 62 is vertically arranged, and a plurality of spaced protrusions 621 are provided on the side of the second buffer strip 62 near the tabletop glass 30. A drainage portion 622 for water passage is formed between two adjacent protrusions 621. The first buffer strip 61 and the second buffer strip 62 are arranged adjacent to each other. Specifically, the first buffer strip 61 is installed in the receiving groove 13 of the upper frame 10, and the second buffer strip 62 is installed on the inner side of the first mounting frame 22 of the lower shell 20. The seepage channel 611 and the drainage section 622 are connected, so that water dripping onto the glass tabletop 30 can flow through the seepage channel 611 and then along the drainage section 622.

[0056] The lower housing 21 has a flow guide groove 231 located inside the first mounting frame 22, and a through flow guide hole 232 is formed at the bottom of the flow guide groove 231. The second buffer strip 62 is located above the flow guide groove 231. Water flowing along the guide section 622 flows downward into the flow guide groove 231, and then flows downward out of the split-type tabletop module 100 along the flow guide hole 232. Preferably, the dimensions of the flow guide groove 231 in the inward and outward directions are greater than or equal to the dimensions of the second buffer strip 62 in the inward and outward directions, with the direction closer to the center of the lower housing 21 being the inward direction and the opposite being the outward direction.

[0057] The water seepage groove 611 on the first buffer strip 61, the drainage part 622, the guide groove 231, and the guide hole 232 on the second buffer strip 62 form a guide channel for water dripping onto the tabletop glass 30. This allows the water dripping onto the tabletop glass 30 to be guided through the gap between the tabletop glass 30 and the upper frame 10 and the lower shell 20, and then flow downwards out of the split tabletop module 100.

[0058] In this embodiment, the tabletop glass 30 is square, the upper frame 10 is square, the first mounting frame 22 is square, and the first buffer strip 61 and the second buffer strip 62 are also squares formed by four sides.

[0059] See Figure 3 As shown, the lower shell 20 also has a lower side frame 26 extending upward along the edge of the lower shell 21, and the upper frame 10 has an outer side frame 12 covering the outside of the lower side frame 26. The upper frame 10 and the lower shell 20 are fixed by fasteners 1. Specifically, the upper frame 10 has a recessed fastening groove 15, and a through hole 151 is formed at the bottom of the fastening groove 15. The lower shell 20 has a threaded post 27 that matches the fastener 1. The fastener 1 has a fastening cap 101 and a fastening post 102. The height of the fastening cap 101 is less than the depth of the fastening groove 15, that is, the fastening cap 1 is located inside the fastening groove 15. Preferably, the ratio of the depth of the fastening groove 15 to the height of the fastening cap 101 is 1.5-2.5. A sealing cap 2 is fastened to the top of the fastening groove 15 to prevent water from entering the fastening groove 15. The upper surface of the sealing cap 2 is set higher than the upper surface of the fastening groove 15 so that the items placed in the fastening groove 15 of the table module 30 can come into contact with the sealing cap 2 first, which plays a buffering and protective role.

[0060] See Figures 9-22 The image shows a second embodiment of the washing machine with a split countertop module proposed in this invention. The difference between this embodiment and the first embodiment is that a main control component 40 is provided on the split countertop module 100, and the washing machine is still provided with an observation module 50. Other aspects can adopt the same structure as the first embodiment.

[0061] See Figure 10 and Figure 11As shown, the observation module 50 includes a camera module 52 and a protective sleeve 53. The camera module 52 has a camera 521 for capturing images of the inside of the washing machine drum. The protective sleeve 53 is installed on the washing machine, and the camera module 52 is located inside the protective sleeve 53. The protective sleeve 53 has a sleeve body 531, a shooting port 532 opened on the sleeve body 531, and a light-transmitting protective lens 533 sealing the shooting port 532. By setting up the observation module 50, the situation inside the washing machine drum can be observed, and the washing process can be observed during the washing machine's operation. The protective sleeve 53 protects the camera module 52 and allows it to be installed on the washing machine. The protective lens 533 allows the camera 521 to be installed inside the protective sleeve 53, enabling it to capture images of the inside of the drum. This helps to protect the camera 521 and allows for observation of the situation inside the drum.

[0062] The camera 521 is located inside the protective lens 533, that is, the camera 521 and the protective lens 533 are arranged adjacent to each other; a sealing ring 534 is provided between the protective lens 533 and the shooting port 532 to prevent water from entering the protective cover 53.

[0063] The camera module 52 also has a light 522 extending from the protective sleeve 53. The light 522 provides illumination for the camera 521 and can also serve as a drum light for the washing machine. An opening is provided on the sleeve 531, through which the light 522 extends. The protective sleeve 53 is a cylindrical shape with one open end; the opening is located at the bottom of the protective sleeve 53, and the camera opening 532 is located on the cylindrical wall of the protective sleeve 53. A sealing gasket 54 is placed between the light 522 and the opening, ensuring a seal between the light 522 and the opening.

[0064] The camera module 52 is fixed inside the protective sleeve 53. Specifically, the camera module 52 has a fixing ear plate 523. The camera module 52 is fixed inside the protective sleeve by fasteners. The protective sleeve 53 has a fastening groove 536 that matches the fasteners. Fixing the camera module 52 inside the protective sleeve 53 by fasteners helps to ensure the stability and firmness of the camera module 52 after it is fixed.

[0065] See Figure 17 and Figure 18As shown, the observation module 50 is mounted on the washing machine's window gasket 200. This mounting on the window gasket 200 reduces the transmission of vibrations during washing machine operation to the protective cover 53, thus providing shock absorption. Furthermore, mounting on the window gasket 200 avoids obstructing the washing machine's washing space. The washing machine's window gasket 200 has a first mounting portion 201 for mounting the protective cover 53. The first mounting portion 201 has a first mounting hole 2011 formed in the window gasket 200, into which the protective cover 53 is inserted. The first mounting portion 201 also has a first mounting cylinder 2012 extending from the first mounting hole 2011 away from the center of the window gasket 200. The first mounting cylinder 2012 is fitted onto the outside of the protective cover 53. The first mounting cylinder 2012 increases the contact area between the protective cover 53 and the first mounting cylinder 2012, improving the stability of the protective cover 53 after installation and preventing rotation of the protective cover 53.

[0066] The protective sleeve 53 is snapped and fixed inside the first mounting cylinder 2012. The first mounting cylinder 2012 has at least one pair of opposing bayonet slots 20121. The protective sleeve 53 has a buckle 537 that matches the bayonet slots 20121, and the buckle 537 engages within the bayonet slots 20121. By providing the bayonet slots 20121 and the buckle 537, the installation and fixing of the protective sleeve 53 is facilitated, thereby improving installation efficiency.

[0067] The washing machine is equipped with a spray head 70 for spraying and protecting the lens 533. A second mounting part 202 for mounting the spray head 70 is provided on the window gasket 200 of the washing machine. The spray head 70 is used to spray and protect the lens 533 and the observation window glass.

[0068] The observation module 50 also includes a display component 51, which displays images captured by the camera module 52. The display component 51 is mounted on the split-type countertop module 100 of the washing machine. The display component 51 has a display screen 511, which is sealed to the upper frame 10. A second sealing strip 512 is provided between the display glass 511 and the upper frame 10. The countertop module 100 also has a main control component 40 mounted on the upper frame 10 and the lower shell 20. The main control component 40 is arranged side by side with the display component 51. By placing the main control component 40 on the split-type countertop module 100, the control panel is omitted, which helps to reduce the installation and fixing of the control panel and improves assembly efficiency. Furthermore, placing the main control component 40 between the upper frame 10 and the lower shell 20 eliminates the need for components such as the main control board bracket and lamp holder, which helps to reduce the number of components in the main control component 40, reduce the procurement cost of components, and reduce the assembly steps of the main control component 40, thereby improving the installation efficiency of the main control component 40 and reducing manufacturing costs.

[0069] See Figure 21As shown, the main control component 40 also includes a display panel 41 located below the lower housing 20, a display film 43 located above the lamp holder 42, a main control glass 45 sealed to the upper frame 10, and a touch film 44 located below the main control glass 45. The display film 43 is attached to the upper end of the lamp holder 42, and the touch film 44 is attached to the lower end surface of the main control glass 45, with the display film 43 and the touch film 44 spaced apart. Preferably, the gap H between the display film 43 and the touch film 44 is 0.1mm to 0.3mm.

[0070] The split-type tabletop module 100 also has a tabletop glass 30 disposed between the upper frame 10 and the lower shell 20. The main control component 40 and the tabletop glass 30 are arranged front and rear, with the main control component 40 located in front of the tabletop glass 30. The main control component 40 and the display component 51 are arranged side by side. The lower shell 20 is provided with a rear receiving groove 23 for accommodating the tabletop glass 30, a front receiving groove 24 for accommodating the main control glass 45, and a front receiving groove 29 for accommodating the display component 51. A first sealing strip 46 is provided between the main control component 40 and the upper frame 10 to achieve a seal between the main control glass 45 and the upper frame 10. A second sealing strip 512 is provided between the display glass 511 and the upper frame 10 to prevent water seepage.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
