Description

Technical Field

[0001] The invention relates to the technical field of household washing machines, and in particular to a novel small-sized washing machine. Background Art

[0002] With the improvement of living standards, people are yearning for a better life and paying more attention to health. Classified and timely washing of socks, underwear and baby clothes has become a new demand. To meet these demands, different types of small washing machines are already on the market.

[0003] For example, a new patent with the authorization publication number [CN204875227U] discloses a portable laundry device, including a base, a motor, a gear plate, an upper cover, a impeller, a locking cover, and a power supply device; the gear plate is mounted on a pillar in the middle of the base through a bearing, the motor is mounted in the base in a ring shape, the motor is meshed with the outer edge of the gear plate through a transmission shaft, a spline shaft is provided on the upper part of the gear plate, the impeller is installed on the spline shaft through a spline hole, and the impeller is locked on the spline shaft through the locking cover, the upper cover is arranged between the impeller and the gear plate, and the upper cover is fixed to the base through the spline shaft; the volume and weight are reduced several times, especially suitable for clothes that are small in size and need to be changed frequently, such as socks, underwear, baby clothes, etc. Although the structural design is simple, it cannot solve the problem of drying clothes.

[0004] In addition, there are other small washing machine products with other structural designs on the market. Generally, the overall size of the traditional washing machine is reduced. However, this method will reduce the effective proportion of the washing space (effective proportion of the washing space = washing space volume / washing machine volume). The structure is relatively complex and the design cost is high. In addition, the small washing space cannot achieve good efficiency utilization during use, and the marketing effect may also be relatively poor. Summary of the invention

[0005] The present invention mainly aims at the problem of poor effective space occupancy rate of existing small washing machines, and proposes a new type of small washing machine. By establishing a flexible connection between the washing drum and the box body, the traditional washing machine outer drum structure is omitted, so that the box body also has the function of a water drum, which effectively improves the occupancy rate of the washing space and makes the overall structure of the washing machine more compact and exquisite.

[0006] The present invention is implemented by adopting the following technical scheme: a novel small-sized washing machine comprises a base, a box body, a control panel and an upper cover assembly, wherein the base is arranged at the bottom of the box body and the upper cover assembly is arranged at the top of the box body;

[0007] The box body is provided with a washing drive assembly, which includes a washing drum assembly, a motor and a motor fixing seat. The motor is arranged below the washing drum assembly, and its output shaft is connected to the bottom of the washing drum assembly to drive the washing drum assembly to rotate. The motor is fixed on the motor fixing seat, and the motor fixing seat is sealedly connected to the box body through a flexible connector. The space above the plane where the flexible connector is located is a washing water storage space, that is, the space formed by the box body, the motor fixing seat and the flexible connector is a washing water storage space.

[0008] The flexible connector is an annular structure with a drain port on it. A drain valve is installed at the drain port. After washing or during rinsing and dehydration, the water in the box is discharged to the outside of the machine. The outer annular edge of the flexible connector is fixedly connected to the box and crimped by a fixed block. The inner annular edge of the flexible connector is fixed to the motor fixing seat and connected by a flexible connector steel wire. The washing drum assembly is obviously located in the washing water storage space. The washing drum assembly is driven to rotate by a motor. Combined with the connection and matching method of the flexible connector and the box, the outer drum of the traditional washing machine is omitted, so that the box is used as a water storage drum, which effectively saves and simplifies the washing machine space and increases the effective proportion of the washing space.

[0009] Furthermore, in order to reduce the transmission of force when the washing drum assembly rotates, the annular structural body of the flexible connector is a downwardly protruding arc structure to weaken the impact of the force on the box body during rotation, thereby achieving the use effect when the outer drum is omitted.

[0010] Furthermore, the washing drum assembly includes a washing drum and an agitator, wherein the agitator is fixedly arranged at the bottom of the washing drum, a second through hole is arranged on the agitator, and a plurality of agitating protrusions are arranged on the inner side wall of the agitator along its circumference.

[0011] Furthermore, in order to achieve a better shock absorption effect, a shock absorbing damper is also arranged on the motor fixing seat, and the shock absorbing damper is fixedly arranged between the motor fixing seat and the base.

[0012] Furthermore, a heating plate is provided on the fixed block, and the heating plate is electrically connected to the control board. The heating plate heats the washing water to a specified temperature according to the selected program, thereby heating the water, washing clothes with warm water, and improving the washing effect.

[0013] Furthermore, the box body is provided with an overflow port, and when the water reaches a certain water level, water flows out from the overflow port.

[0014] Furthermore, the flexible connector is made of flexible materials such as rubber or silicone.

[0015] Furthermore, the base is also provided with rubber bottom corners to increase the overall stability of the washing machine when it is placed and to achieve a shock-absorbing effect.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] This plan proposes a new type of small washing machine, which eliminates the outer drum structure of the existing small washing machine, combines the existing washing system with the box through a flexible connector, and gives the box the function of holding water; and eliminates the original lifting system of the washing part, and adds a bottom balancing shock absorption system, that is, a flexible connector, shock absorber and other structural designs, to increase the effective proportion of the washing space, achieve better use effect, and have higher practical application and promotion value.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] A new type of small washing machine omits the outer drum of a traditional washing machine, so that the box can also hold water. Figure 1 and Figure 2As shown, it includes a base 1, a box body 2 and an upper cover assembly 3, the base 1 is arranged at the bottom of the box body 2, the upper cover assembly 3 is arranged at the top of the box body 2, and a control panel 31 is arranged in the upper cover assembly 3; a washing drive assembly is arranged in the box body 2, and the washing drive assembly includes a washing drum assembly, a motor 4 and a motor fixing seat 6, the washing drum assembly includes a washing drum 21 and an agitator 23, the agitator 23 is fixedly arranged at the bottom of the washing drum 21, and a plurality of stirring protruding ribs 232 are arranged on the inner side wall of the agitator 23 along its circumference, and a plurality of first through holes 211 are arranged on the side wall of the washing drum 21, and the motor 4 is arranged below the washing drum 21, and the output shaft of the motor 4 is fixedly connected to the bottom of the washing drum 21 through the flange 5, and the rotation of the output shaft of the motor 4 drives the flange 5 to rotate, thereby driving the washing drum 21 and the agitator 23 to rotate synchronously;

[0028] The motor 4 is fixed in the box 2 through the motor fixing seat 6, and the motor fixing seat 6 and the box 2 are sealed by a flexible connector 8, which is made of a flexible material such as rubber or silicone. The space in the box above the plane where the flexible connector 8 is located is the washing water storage space, that is, the upper space formed by the box 2, the motor fixing seat 6 and the flexible connector 8 is the washing water storage space. Figure 7 and Figure 8 As shown, the flexible connector 8 is an annular structure, and the annular structure body of the flexible connector 8 is an arc-shaped structure 82 protruding downward. In this embodiment, the annular structure can adopt a circular ring structure or an elliptical ring structure, etc., and can be designed specifically according to actual conditions, and no specific restrictions are made here. In this solution, the washing drum 21 is driven to rotate by the motor 4, and combined with the connection and cooperation method between the flexible connector 8 and the box body 2, the outer drum of the traditional washing machine is omitted, so that the box body 2 also has the function of holding water, effectively saving and simplifying the washing machine space, and increasing the effective proportion of the washing space.

[0029] Continue to refer Figure 1 and Figure 2 The annular outer edge of the flexible connector 8 is fixedly connected to the box body 2 and crimped by the fixing block 22. The annular inner edge of the flexible connector 8 is fixed to the motor fixing seat 6 and connected by the flexible connector wire. Figure 4 As described above, a drain outlet 81 is provided on the flexible connector 8 (a drain valve is installed at the drain outlet 81), and the water in the box 2 is discharged to the outside of the washing machine after washing is completed or during rinsing and dehydration. A heating plate can also be provided on the fixed block 22, and the heating plate is electrically connected to the control board 31. The control board 31 controls the heating of the washing water, so that warm water can be used to wash clothes and the washing effect can be improved.

[0030] In addition, the upper cover assembly 3 is also provided with a fan 32 and a heater 33. The heater 33 is located below the fan 32 and is provided at the exhaust port of the fan 32. The fan 32 and the heater 33 are protected by a housing 35. The housing is provided with an air outlet 36. The heated hot air is blown out from the air outlet 36 to dry the clothes. In addition, in this embodiment, the air outlet 36 extends into the agitator 23. The middle part of the agitator 23 is provided with an upwardly protruding windward opening 231. The windward opening 231 is connected to the air outlet 36. In this embodiment, Figure 5 and Figure 6 As shown, the agitator 23 is provided with a second through hole 234, the inner side wall of the agitator 23 is provided with a plurality of stirring protruding ribs 232 along its circumference, the bottom of the agitator 23 is provided with a plurality of protruding ribs 233, the protruding ribs 233 are provided with vents, the air outlet 36 extends into the agitator 23, and a drying ventilation duct 235 is formed between the protruding ribs 233 and the washing drum 21. During the drying process, the gas flows as shown in FIG. Figure 1 Indicated by the arrow.

[0031] In addition, a motor protection cover 41 is provided on the outside of the motor 4. In order to achieve a better shock-absorbing effect, a shock-absorbing damper 7 is also provided on the motor fixing base 6, and the other side of the shock-absorbing damper 7 is fixed on the base 1; the base 1 is also provided with a rubber bottom angle 11 to increase the overall stability of the washing machine when it is placed and achieve a shock-absorbing effect.

[0032] In this embodiment, because the heating body 33 is located in the washing drum 21 after the upper cover assembly 3 is closed, in order to prevent the washing water from affecting the heating body 33 during washing, the water inlet of the washing machine is controlled by the flow meter 9 in this scheme, and the highest water level is located below the heating body 33. For the sake of safety, an overflow port 24 is provided on the housing 2, and the heating body 33 is arranged below the fan. The horizontal plane where the heating body 33 is located is higher than the horizontal plane where the overflow port 24 provided on the housing 2 is located. For example, the height of the heating body 33 above the overflow port 24 is 5-10mm. When the electronic control part fails and water continues to enter, it reaches a certain water level and water flows out from the overflow port, thereby effectively protecting the heating body 33.

[0033] In addition, an air inlet 34 is provided on the upper cover assembly. The air inlet of the upper cover is designed to allow dry air from the outside to enter the machine to replace the wet air inside. An exhaust port 12 is provided on the box body 2. The fan 32 is the power source of the air duct circulation, and the air after drying the clothes is discharged from the exhaust port 12. The wind is heated when passing through the heating body. A temperature sensor is provided on the heating body 33. The heated dry air enters the inner cavity of the agitator 23. The agitator 23 and the washing drum 21 form a hot air flow cavity at the bottom (such as Figure 1In the drying process, the washing drum is rotated forward and reversely at a specific speed and regularity, and the hot air is blown directly onto the clothes through the second through hole on the agitator 23. After the hot air dries the clothes, the air is discharged through the exhaust port 12 to achieve drying of the clothes.

[0034] In this solution, the water storage system consists of a motor fixing base, a flexible connector and a box body (the traditional washing machine consists of an outer drum and a motor clutch fixing base); since the washing module is a moving part during the washing and dehydration process, the original solution needs to reserve a gap between the inner washing drum and the outer water storage drum, as well as a gap between the outer water storage drum and the box body, resulting in a relatively small effective proportion of the washing space, which is particularly prominent in small washing machines; for example, for a small washing machine with a nominal weight of 1kg, the space occupied by this solution is only about 56% of that of the traditional solution, that is, for washing machines of the same capacity, this solution has a smaller volume. The main reason is that this solution eliminates the outer water storage drum and directly connects the motor fixing base to the box body, eliminating the gap between the outer water storage drum and the box body, thereby reducing the size of the small washing machine and achieving the purpose of increasing the effective proportion of the washing space.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
