Description

Technical Field

[0001] This invention belongs to the field of clothing processing equipment, and more specifically, relates to a twin-tub washing machine. Background Technology

[0002] With the improvement of living standards, washing machines have become an indispensable household item. Among them, twin-tub washing machines remain popular. Most twin-tub washing machines on the market have a one-piece tub structure. When the user is running at full load, only a single wall structure can protrude from the top edge of the tub opening. The fit between the large frame and this position is made into a U-shape. When the height-to-width ratio of the U-shape is large, the water sealing effect is good. However, the mold for the U-shape structure is made of thin iron, which is easy to break. It is generally made to be more than 3.5mm thick. The gap between the U-shape and the one-piece tub is greater than 1mm, which makes it easy for water to splash. The current best solution is to attach a sealing strip along the water flow direction to block it, but the sealing strip is not very effective. Water will still splash after more than three cycles, which reduces the user experience.

[0003] Chinese patent application CN2390903Y discloses a twin-tub washing machine, specifically relating to the fastening method between the upper frame and the tub of the twin-tub washing machine. The washing machine includes an upper frame, outer shell, integrated tub, and base. The invention is characterized by the outer shell and integrated tub being a single injection-molded unit with smooth transitions at the four corners and sides using rounded arcs. Reinforcing ribs are provided on the tub wall, and the upper frame and tub are fastened together using a clamping fastening method. However, this structure results in a poor fit between the top surface of the large frame and the integrated tub, as it is a surface fit. This also leads to a poor appearance of the large frame. Furthermore, when the washing machine is running at full load and during the spray rinsing process, water splashes along the lower edge of the large frame.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a twin-tub washing machine, including an integrated tub and a large frame. The large frame is fitted on the top of the upper edge of the integrated tub, which can increase the rigidity of the integrated tub. A stepped structure is provided on the integrated tub and abuts against the limiting part on the large frame to form a sealed pressure chamber, which can store the washing water in the pressure chamber and form a certain static pressure on the bottom to prevent water from splashing out during washing.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a twin-tub washing machine, characterized in that it includes,

[0007] An integrated barrel, wherein the inner wall of the integrated barrel is provided with a first step structure;

[0008] The large frame is fitted onto the top of the outer edge of the integrated tub. The inner wall of the large frame has a protruding limiting part that abuts against the first step structure to form a sealed pressure chamber for storing washing water and preventing it from splashing out of the tub.

[0009] This invention improves the strength of the integrated tub structure by setting a first step structure on the integrated tub, which abuts against a first limiting part set on the inner wall of the large frame. The large frame is fitted on the top of the integrated tub, forming a pressure chamber. When the washing machine is running, splashed water is stored in the pressure chamber, and a certain static pressure is formed at the bottom of the pressure chamber to prevent water from splashing out of the integrated tub, thus improving the user's washing experience.

[0010] Furthermore, the first step structure is disposed on the upper edge of the inner wall of the integrated barrel;

[0011] The pressure chamber is located between the first limiting part and the first stepped structure at the opposite position.

[0012] Furthermore, the bottom surface of the first limiting part is sealed to the bottom surface of the first stepped structure;

[0013] A gap is formed between the side of the first step structure and the first limiting part.

[0014] Furthermore, the side of the first stepped structure extends obliquely from the bottom of the first stepped structure to the top of the double-section body.

[0015] Furthermore, the first limiting part abuts against the bottom surface of the first stepped structure at one end near the inside of the barrel, and protrudes radially from the bottom surface of the first stepped structure.

[0016] Furthermore, the top of the integrated barrel is smoothly connected to the side.

[0017] Furthermore, the outer wall of the integrated barrel is also provided with a second step structure, which is arranged opposite to the first step structure;

[0018] The outer periphery of the large frame is provided with a second limiting part, which abuts against the second step structure.

[0019] Furthermore,

[0020] The large frame includes a first annular plate and a second annular plate, the first annular plate and the second annular plate are disposed on the integrated barrel, and the second annular plate abuts against the second step structure;

[0021] A connecting plate, the two ends of which are respectively connected to a first annular plate and a second annular plate.

[0022] Furthermore, the first limiting part is provided to protrude downwards from the connecting plate.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0024] (1) The present invention provides a first step structure on the top of the integrated tub, which abuts against the first limiting part on the large frame and forms a funnel-shaped pressure chamber. During washing, the splashed water is stored in the pressure chamber, which forms a certain static pressure on the bottom of the pressure chamber and prevents the water from splashing out further.

[0025] (2) By setting the first step structure and the second step structure to abut against the first limit part and the second limit part respectively, the second limit part and the second step structure are fitted with a small gap to meet the installation requirements and facilitate the installation and disassembly of the large frame. At the same time, the strength of the integrated tub is increased. The first limit part and the first step structure are fitted without gap to change the direction of water flow during washing and reduce the impact force of water.

[0026] (3) By forming an inverted U-shaped structure with the first limiting part and the second limiting part, and setting a chamfer structure at the top of the integrated barrel near the inner wall, it is convenient for the large frame to be installed on the integrated barrel.

[0037] like Figures 1 to 3 As shown, the present invention provides a twin-tub washing machine, comprising an integrated tub 1 and a large frame 2.

[0038] The inner wall of the integrated barrel 1 is provided with a first step structure 12.

[0039] The large frame 2 is fitted onto the top of the outer edge of the integrated barrel 1.

[0040] The inner wall of the large frame 2 is provided with a protruding first limiting part 22, which abuts against the first step structure 12 to form a sealed pressure chamber 3, which is used to store washing water and prevent washing water from splashing out of the tub.

[0041] The present invention provides a first step structure 12 on the integrated tub 1, which abuts against the first limiting part 22 on the large frame 2, forming a sealed pressure chamber 3. When washing clothes, the splashed water is stored in the pressure chamber 3, and a certain static pressure is formed at the bottom of the pressure chamber 3, further preventing water from splashing out, improving the practical effect and enhancing the user experience.

[0042] During installation, the large frame 2 is directly fitted onto the top of the integrated tub 1, so that the first step structure 12 on the integrated tub 1 abuts against the first limiting part 22 on the large frame 2, so that the large frame 2 and the inner wall of the integrated tub 1 form a sealed pressure chamber 3. In use, it stores washing water and forms a certain static pressure at the bottom of the pressure chamber 3, changing the direction of water flow and reducing the impact force of water. The structure is simple, meets the installation requirements, and does not reduce the aesthetics of the tub structure.

[0043] Furthermore, the first step structure 12 is disposed on the upper edge of the inner wall of the integral barrel 1.

[0044] The pressure chamber 3 is located between the first limiting part 22 and the first step structure 12.

[0045] By placing the pressure chamber 3 between the first limiting part 22 and the first step structure 12, it is convenient to store the washing water inside the integrated tub 1 and prevent the washing water from splashing from the lower edge of the large frame 2 when the washing machine is running at full load, thus reducing the user experience.

[0046] Furthermore, the bottom surface of the first limiting part 22 is sealed to the bottom surface of the first step structure 12.

[0047] A gap is formed between the side of the first step structure 12 and the first limiting part 22.

[0048] The first limiting part 22 and the first step structure 12 are fitted without clearance.

[0049] By fitting the first limiting part 22 with the first step structure 12 without gap, the sealing performance of the washing machine's installation structure is improved, the amount of water splashing during washing is reduced, and a sealed pressure chamber 3 is formed, further increasing the water sealing characteristics of the structure and improving the practicality of the equipment.

[0050] When the twin-tub washing machine is fully loaded for washing, the washing water in the integrated tub 1 moves. The first limiting part 22 and the first step structure 12 are in close contact, which can change the direction of the water flow when the washing water touches the first step structure 12, reduce the impact force of the washing water, reduce the amount of splashing water, and improve the user experience.

[0051] Furthermore, the side of the first step structure 12 extends obliquely from the bottom of the first step structure 12 to the top of the integrated barrel 1.

[0052] Specifically, such as Figure 2As shown, by tilting the side of the first step structure 12, the water volume in the pressure chamber 3 is increased, further increasing the static pressure of the washing water on the bottom of the pressure chamber 3, improving the effect of preventing further splashing when the device is in use, and enhancing the user experience.

[0053] Furthermore, the first limiting part 22 abuts against the bottom surface of the first stepped structure 12 at one end near the inside of the barrel, and protrudes radially from the bottom surface of the first stepped structure 12.

[0054] By having the first limiting part 22 protrude radially from the bottom surface of the first stepped structure 12, the washing water in the integrated tub 1 can change its flow direction when it comes into contact with the first limiting part 22, thereby reducing the impact force of the water and lowering the splashing rate of the washing water. A gap is provided between the large frame 2 and the top of the integrated tub 1.

[0055] Furthermore, the top of the integrated barrel 1 is smoothly connected to the inclined surface.

[0056] The smooth transition connection is a chamfered structure 14.

[0057] The present invention provides a chamfered structure 14 at one end of the top of the integrated tank 1, which is connected to the side of the first stepped structure 12. The gap between the large frame 2 and the integrated tank 1 further increases the water storage capacity of the pressure chamber 3. At the same time, it facilitates the disassembly and installation of the large frame 2 on the integrated tank 1.

[0058] Specifically, such as Figures 2 to 3 As shown, the chamfered structure 14 is disposed at one end of the inner wall of the top of the integrated barrel 1 and is connected to the side of the first step structure 12. The side is inclined to facilitate the cooperation between the first step structure 12 and the first limiting part 22, thereby improving the strength of the integrated barrel 1. At the same time, it also facilitates the installation of the large frame 2 on the integrated barrel 1.

[0059] Furthermore, the area of ​​the pressure chamber 3 gradually decreases from the top of the integrated barrel 1 along the axial direction to the second step.

[0060] The pressure chamber 3 is funnel-shaped.

[0061] This invention increases the amount of washing water that can be stored by designing the pressure chamber 3 in a funnel shape. At the same time, it increases the pressure of the washing water in the pressure chamber 3, preventing further splashing of the washing water, thus improving the practicality of the equipment and enhancing the user experience.

[0062] By setting the chamfered structure 14 at the top of the integrated barrel 1, it is convenient for the large frame 2 to be installed on the integrated barrel 1. The chamfered structure 14 is connected to the inclined surface of the first step structure 12, so that the wall thickness of the integrated barrel 1 from the top to the first step structure 12 gradually increases and the area of ​​the pressure chamber 3 gradually decreases, forming a funnel-shaped pressure chamber 3. When the first step structure 12 and the first limiting part 22 are in a gapless fit, the water flow direction is changed and the impact force of the water is reduced.

[0063] Furthermore, the outer wall of the integrated barrel 1 is also provided with a second step structure 11, which is arranged opposite to the first step structure 12.

[0064] By setting the first step structure 12 and the second step structure 11, when the large frame 2 and the integrated tub 1 are engaged, the engagement point of the large frame 2 and the integrated tub 1 is supported, making the engagement of the integrated tub 1 and the large frame 2 more tight and increasing the stability of the large frame 2 of the twin-tub washing machine.

[0065] The outer periphery of the large frame 2 is provided with a second limiting part 21, which abuts against the second step structure 11.

[0066] Furthermore, the second limiting part 21 is sealed to the opposite surface of the second step structure 11.

[0067] The bottom surface of the second limiting part 21 is in clearance fit with the bottom surface of the second step structure 11.

[0068] By setting the second step structure 11 on the outer wall of the integrated barrel 1 and abutting against the second limiting part 21, and with a gap fit between the bottom surface of the second limiting part 21 and the bottom surface of the second step structure 11, the large frame 2 can be separated from the integrated barrel 1 through the gap at the abutment point between the second limiting part 21 and the second step structure 11 during maintenance, which facilitates the installation and disassembly of the integrated barrel 1 and the large frame 2.

[0069] The first limiting part 22 and the second limiting part 21 form an inverted U-shaped structure, so that the large frame 2 is fitted onto the top of the integrated barrel 1.

[0070] The present invention provides a first limiting part 22 and a second limiting part 21 on the large frame 2, and forms an inverted U-shaped structure on the body of the large frame 2, so that the large frame 2 can be better installed with the integrated barrel 1. The large frame 2 is directly snapped onto the integrated barrel 1 through the inverted U-shaped structure, and the first limiting part 22 and the second limiting part 21 abut against the first step structure 12 and the second step structure 11 respectively, thereby increasing the strength of the integrated barrel 1 structure.

[0071] Specifically, by setting the first step structure 12 on the upper edge of the inner wall of the integrated tub 1 and the second step structure 11 on the upper edge of the outer wall of the integrated tub 1, the first step structure 12 and the second step structure 11 are arranged opposite to each other and abut against the first limiting part 22 and the second limiting part 21 on the large frame 2, respectively. At the same time, the first limiting part 22 and the first step structure 12 are fitted without gap, which facilitates the tight connection between the large frame 2 and the integrated tub 1 inside the tub, changes the direction of water flow during washing, and reduces the impact force of water; the second limiting part 21 and the second step structure 11 are fitted with a small gap, which makes it convenient for the large frame 2 to be installed and disassembled.

[0072] Specifically, by wrapping the upper edge of the integrated tub 1 with the large frame 2, the rigidity of the top of the integrated tub 1 is increased, and water is prevented from splashing out of the integrated tub 1 during washing or spin-drying, thus improving the user experience.

[0073] During installation, the large frame 2 is placed above the integrated barrel 1, and the first limiting part 22 on the large frame 2 is abutted against the first step structure 12 without gap. Then, the second limiting part 21 is abutted against the second step structure 11. There is a gap at the abutment point between the second step structure 11 and the second limiting part 21, which facilitates the removal of the large frame 2 from the integrated barrel 1 during disassembly. The gap is small, which meets the installation requirements and does not affect the aesthetics of the fit between the large frame 2 and the integrated barrel 1.

[0074] The inner wall of the integrated barrel 1 is also provided with reinforcing ribs 13, which further increases the strength of the barrel wall of the integrated barrel 1.

[0075] By setting reinforcing ribs 13 on the inner wall of the integrated tub 1, the strength of the tub wall is increased, the weight of the entire twin-tub washing machine frame 2 is reduced, the complexity of the integrated tub 1 structure is reduced, and the deformation of the integrated tub 1 structure due to the low strength of the tub wall and the weight of the water and clothes inside the integrated tub 1 is prevented, which would reduce the strength of the tub wall and affect the aesthetics of the washing machine.

[0076] Furthermore, the large frame 2 includes a first annular plate 23 and a second annular plate, the first annular plate and the second annular plate being disposed on the integrated barrel 1, and the second annular plate abutting against the second step structure 11.

[0077] A connecting plate 24, the two ends of which are respectively connected to a first annular plate 23 and a second annular plate.

[0078] The first limiting part 22 is provided on the connecting plate 24 and protrudes downward.

[0079] This invention provides a first step structure 12 and a second step structure 11 on the side wall and inner wall of the upper edge of the integrated tub 1, respectively, which abut against the first limiting part 22 and the second limiting part 21 on the large frame 2. The large frame 2 forms an inverted U-shaped structure through the first limiting part 22 and the second limiting part 21. During installation, the large frame 2 wraps around the upper edge of the integrated tub 1, increasing the rigidity of the integrated tub 1. At the same time, the second limiting part 21 and the second step structure 11 have a small gap fit, making it easy to install and disassemble the large frame 2 and the integrated tub 1, while also meeting installation requirements and increasing aesthetics. The first limiting part 22 and the first step structure 12 have a gapless fit, which can change the water flow direction and reduce the water flow pressure during washing.

[0080] By setting a chamfered structure 14 at one end of the top of the integrated tub 1, it is convenient to install and disassemble the large frame 2. Together with the first limiting part 22 and the second step structure 11 on the large frame 2, a sealed pressure chamber 3 is formed. When the washing machine is fully loaded, the splashed water can be stored in the pressure chamber 3. At the same time, a certain static pressure is formed at the bottom of the pressure chamber 3 to further prevent water from splashing out and improve the user experience.

[0081] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced.
