Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of washing machines, and particularly relates to a washing machine and a control method thereof. BACKGROUND

[0002] The pulsator washing machine is a kind of washing machine, and the bottom of the pulsator washing machine is provided with a disc-shaped pulsator with protruding ribs. Under the driving of the pulsator, the water flow in the washing barrel forms vortex flow that rotates right and left alternately, and drives the fabrics to rotate and tumble, so that the dirt on the clothes can be removed. There are single-barrel, nested-barrel and double-barrel types. The pulsator washing machine has simple structure, convenient maintenance, high washing efficiency, but has high fabric wear rate and consumes much water.

[0003] Nowadays, with the development of science and technology, new water flow washing machines controlled by computers appear, which adopt large pulsators and concave pulsators. The advantages are that the clothes are less entangled, the washing is uniform, and the fabric wear rate is low. The washing barrel has four types of full plastic, enamel, aluminum alloy and stainless steel.

[0004] The working principle of the pulsator washing machine is that the pulsator installed at the bottom of the washing barrel rotates forward and backward to drive the clothes to continuously turn up and down and left and right, so that the clothes and the barrel wall are gently rubbed in the water to realize decontamination and cleaning under the action of the detergent.

[0005] The existing pulsator washing machine has the following problems: when the pulsator washing machine is filled with water, the washing water flows from the water box in the disc seat area into the washing barrel. Since the distance between the water inlet and the bottom of the washing barrel is large, there is a large water flow sound during the water filling process. The water flow sound during the water filling process is easy to become a noise source, thereby affecting the user's experience.

[0006] In view of this, the present application is proposed. SUMMARY

When the washing machine executes the washing program, the external washing water enters the water inlet channel 3 through the water inlet part 2, and flows into the bottom of the washing tub 1 through the water inlet channel 3. In the prior art, the water inlet mode of the pulsator washing machine is that the external washing water flows into the inner tub 15 from the water box in the disc seat area, at the same time, due to the existence of the height of the inner tub 15, the distance from the water outlet of the water box in the disc seat to the bottom of the inner tub 15 is large, and there is a large water flow sound in the water inlet process, which is complained by the user. Compared with the prior art, in the embodiment of the present application, the external washing water flows into the water inlet part 2 and then directly flows into the bottom of the washing tub 1 through the water inlet channel 3 to realize the water inlet process, which avoids the washing water directly flowing from the high water outlet into the bottom of the inner tub 15, reduces the water inlet sound in the water inlet process, further realizes the noise reduction, and improves the user experience.

[0045] Embodiment one

[0046] As Figure 2 shown, in the embodiment of the present application, a washing machine is introduced, the inner peripheral wall of the washing tub 1 of the washing machine is provided with a water inlet part 2, the lower end of the water inlet part 2 is communicated with a water inlet channel 3, the water inlet channel 3 is arranged closely to the inner peripheral wall of the washing tub 1, the lower end of the water inlet channel 3 extends to the bottom of the washing tub 1. When the washing machine executes the washing program, the external washing water enters the water inlet channel 3 through the water inlet part 2, and flows into the bottom of the washing tub 1 through the water inlet channel 3. In the prior art, the water inlet mode of the pulsator washing machine is that the external washing water flows into the inner tub 15 from the water box in the disc seat area, at the same time, due to the existence of the height of the inner tub 15, the distance from the water outlet of the water box in the disc seat to the bottom of the inner tub 15 is large, and there is a large water flow sound in the water inlet process, which is complained by the user. Compared with the prior art, in the embodiment of the present application, the external washing water flows into the water inlet part 2 and then directly flows into the bottom of the washing tub 1 through the water inlet channel 3 to realize the water inlet process, which avoids the washing water directly flowing from the high water outlet into the bottom of the inner tub 15, reduces the water inlet sound in the water inlet process, further realizes the noise reduction, and improves the user experience.

[0047] The water inlet nozzle 8 is of a conical structure and extends towards the water inlet channel 3, and a gap is provided between the extending end of the water inlet nozzle 8 and the water inlet channel 3. A certain gap is provided between the bottom end of the water inlet nozzle 8 and the upper end of the water inlet channel 3, because the water inlet channel 3 is arranged on the inner circumferential wall of the washing tub 1 and can rotate with the washing tub 1, if the water inlet nozzle 8 is arranged in close contact with the water inlet channel 3, the water inlet effect of the washing machine will be affected, and the washing tub 1 will also rotate.

[0048] As shown in Figure 2 In the embodiment of the present application, the upper end of the water inlet channel 3 is provided with a baffle 13, the lower end of the baffle 13 is fixed to the top of the water inlet channel 3, and the upper end extends obliquely towards the top of the shell 11 and is arranged higher than the water inlet nozzle 8; the extending direction of the baffle 13 is obliquely towards the top of the shell 11 away from the water inlet channel 3. More preferably, the baffle 13 is integrally formed with the water inlet channel 3, and the baffle 13 is arranged at the upper end of the water inlet channel 3 in order to collect washing water at the water inlet channel 3, by arranging the baffle 13, the washing water passing through the water inlet nozzle 8 can be prevented from being sprayed to the periphery of the washing tub 1, so that the washing water is collected at the water inlet channel 3, the water inlet flow is increased, and the excess washing water is prevented from directly flowing into the washing tub 1 from the outside of the water inlet channel 3.

[0049] In the embodiment of the present application, the baffle 13 can be connected to the inner circumferential wall of the washing tub 1 at the front and rear ends, and a closed hollow structure is formed, or the baffle 13 is located in the washing tub 1 and extends forward and rearward, and the lower end is connected to the upper end of the water inlet channel 3, which also allows the washing water to be collected at the water inlet channel 3.

[0050] After the external washing water passes through the water inlet nozzle 8, most of the washing water will be directly sprayed into the water inlet channel 3, and the remaining washing water will be blocked by the baffle 13 and collected at the upper end of the water inlet channel 3 and then flow into the bottom of the washing tub 1 through the water inlet channel 3.

[0051] In the embodiment of the present application, a gap is provided between the bottom end of the water inlet nozzle 8 and the baffle 13. When the washing machine is washing, the washing tub 1 will rotate, and in the case of not affecting the rotation of the washing tub 1, the gap between the water inlet nozzle 8 and the baffle 13 should be as small as possible, and the gap should not be too large, otherwise the water outlet effect of the water inlet nozzle 8 will be affected.

[0052] In the embodiment of the present application, the bottom of the shell 11 of the washing machine is also provided with a positioning device 14, the washing tub 1 can be stopped at a set position through the positioning device 14, and the water inlet nozzle 8 is arranged towards the baffle 13. When the washing tub 1 is stopped at the set position, the water inlet nozzle 8 is arranged towards the baffle 13, which can prevent the water inlet nozzle 8 from spraying washing water to the outside of the water inlet channel 3, and the baffle 13 can block the water inlet nozzle 8 from directly spraying washing water into the washing tub 1.

[0053] Meanwhile, during the washing process, if the washing tub 1 does not stop at the set position, the water inlet nozzle 8 and the baffle 13 are misaligned. At this time, the washing machine will continue to work, and the water inlet method is similar to the existing technology, spraying washing water directly into the washing tub 1 through the water inlet nozzle 8.

[0054] Example 2

[0055] like Figure 1 As shown, in this embodiment of the invention, the difference from Embodiment 1 is that a water inlet section 2 is provided at the upper end of the water inlet channel 3. The bottom of the water inlet section 2 is connected to the water inlet channel 3, and the upper end is opened vertically opposite to the water inlet nozzle 8. Preferably, the water inlet section 2 includes a conical sidewall 21, which forms a water inlet chamber 22, and the water inlet of the water inlet chamber 22 is arranged facing the water inlet nozzle 8. The water inlet process can also be achieved by replacing the baffle with the water inlet section.

[0056] In this embodiment of the invention, the water inlet 2 is positioned near the opening of the washing tub 1, and the water inlet nozzle 8 is positioned facing the water inlet chamber 22. To facilitate the spraying of washing water into the water inlet chamber 22, the water ultimately flows into the bottom of the washing tub 1 through the water inlet channel 3. One end of the water inlet chamber 22 has an opening, and the other end has a water outlet, with the opening facing upwards. The upper opening has a larger diameter than the water outlet to meet the water inlet requirements. The water outlet is detachably connected to the water inlet channel 3. With this configuration, external washing water preferentially passes through the water inlet nozzle 8, which sprays the washing water into the water inlet chamber 22. The water outlet at the bottom of the water inlet chamber 22 allows the washing water to flow into the water inlet channel 3, thus achieving water intake for the washing machine.

[0057] In this embodiment of the invention, the water inlet nozzle 8 is further provided with a flow stabilizing block 9 inside. The flow stabilizing block 9 allows the water in the water inlet nozzle 8 to flow out quickly and spray into the water inlet chamber 22. More specifically, the flow stabilizing block 9 includes a cover and a shielding block. The cover is connected to the top of the shielding block and covers the top of the shielding block.

[0058] It should be noted that during the assembly process, the flow stabilizer 9 needs to be installed inside the water inlet nozzle 8, for example, by welding, at the outlet of the water inlet nozzle 8. The flow stabilizer 9 provides a stable and sufficient flow rate for the rinsing water output from the water inlet nozzle 8, which can be sprayed evenly in the water inlet chamber 22.

[0059] Because of the flow stabilizer 9, the washing water can only flow in through the opening. Compared with the case without the flow stabilizer 9, the width of the water flow is significantly reduced. Therefore, the water flow velocity after passing through the flow stabilizer 9 will be significantly increased, so that the water outlet nozzle 8 has a certain spraying effect and can obtain a better rinsing effect.

[0060] The lowest end of the water inlet nozzle 8 is slightly higher than the uppermost end of the water inlet part 2, so that there is a gap between the water inlet nozzle 8 and the uppermost end of the water inlet part 2, which satisfies that the washing water is sprayed by the water inlet nozzle 8 and does not splash to the outer periphery of the water inlet part 2.

[0061] In the embodiment of the present application, a plurality of overflow holes 4 are further formed in the conical side wall 21, the overflow holes 4 are arranged towards the axis of the washing tub 1, and the overflow holes 4 connect the water inlet chamber 22 with the atmosphere in the washing tub 1. The water inlet part 2 is arranged on the inner peripheral wall of the washing tub 1, and the overflow holes 4 are arranged for two purposes. When the water inlet pressure of the washing machine fluctuates, if the water inlet pressure of the electromagnetic valve 6 is too high and the water inlet flow is greater than the passing capacity of the water inlet flow channel 3, the excess water will flow into the washing tub 1 from the water inlet chamber 22 through the overflow holes 4, so as to avoid waste of the excess washing water. Meanwhile, the overflow holes 4 are arranged towards the axis of the washing tub 1, so as to make the water in the washing tub 1 gather at the bottom of the washing tub 1.

[0062] As shown in Figure 1 In the embodiment of the present application, the washing machine further comprises a control disc seat 12 arranged at the upper end of the shell 11, the control disc seat 12 is provided with a water inlet pipeline 5, the water inlet pipeline 5 is provided with the electromagnetic valve 6, one end of the water inlet pipeline 5 is connected with an external water source, and the other end of the water inlet pipeline 5 is connected with a water inlet hose 7. The electromagnetic valve 6 is arranged on the water inlet pipeline 5, so as to control the water inlet flow of the washing water. The external water source starts to inject the washing water into the washing machine, and at the same time, the electromagnetic valve 6 discharges the washing water into the water inlet chamber 22. After the washing tub 1 reaches the water inlet amount set in the washing program, the external water source stops water inlet, and the washing machine enters the washing clothes program.

[0063] Meanwhile, the other end of the water inlet pipeline 5 is connected with the water inlet hose 7. Since the washing machine will vibrate during the dehydration, the water inlet hose 7 is arranged, so as not to cause the water inlet pipeline 5 to be stressed or damaged, and affect the normal use of the washing machine.

[0064] As shown in Figure 1As shown, in the embodiment of the present application, the water inlet hose 7 extends towards the water inlet chamber 22, and the extending end is connected with the water inlet nozzle 8. The bottom end of the water inlet nozzle 8 is provided with a gap with the uppermost end of the water inlet chamber 22. The external water source passes through the electromagnetic valve 6, the water inlet hose 7 and the water inlet nozzle 8 in sequence from the water inlet pipeline 5, is sprayed into the water inlet chamber 22 through the water inlet nozzle 8, and flows into the bottom of the washing tub 1 through the water inlet flow channel 3. During washing, the washing tub 1 rotates. In the case of not affecting the rotation of the washing tub 1, the gap between the water inlet nozzle 8 and the water inlet chamber 22 should be as small as possible. If the gap is too large, the water outlet effect of the water inlet nozzle 8 will be affected, and the washing water is sprayed around the conical side wall 21 or directly sprayed into the washing tub 1. When the user selects the washing clothes button, opens the upper cover of the washing machine to put in the additive, and presses the start button, the electromagnetic valve 6 is opened, and the external water source starts to inject water into the water inlet part 2. The washing water first flows through the water inlet pipeline 5, the water inlet hose 7 and the water inlet nozzle 8, is sprayed into the water inlet chamber 22 through the water inlet nozzle 8, and then flows into the bottom of the washing tub 1 through the water inlet flow channel 3, so as to realize the washing water inlet process. When the water level reaches the water level switch, the water inlet is stopped, and the washing machine enters the washing clothes program.

[0065] A detergent box 10 is further installed between the water inlet nozzle 8 and the water inlet hose 7, and the detergent box 10 is suitable for containing the detergent.

[0066] The washing machine in the above embodiment further comprises at least one container for containing the additive, the container is the detergent box 10, a liquid suction port for sucking the additive into the washing water inlet pipeline by the negative pressure is arranged in the negative pressure area and is communicated with the detergent box 10 containing the additive, a metering device for detecting the amount of the additive put in is arranged between the liquid suction port and the detergent box 10, and an additive control valve for controlling the on-off between the metering device and the detergent box 10 is arranged.

[0067] The additive automatically added in the washing machine of the present application is the liquid additive for washing clothes such as detergent, softener and disinfectant, and the additive manually added can be washing powder and the above liquid additive. When the additive is automatically added, the amount of the additive required is calculated according to the amount of clothes and / or fabric and / or dirtiness and / or water temperature and / or water quality in the inner tub 15, and then the number of times of sucking the additive into the detergent box 10 by the water flow negative pressure is calculated. The automatic adding device of the present application puts in the additive, and then the external water source is used to inject water. The external water source enters the detergent box 10 through the water inlet pipeline 5 and the water inlet hose 7, dissolves the detergent in the detergent box 10, becomes washing water, is sprayed into the water inlet chamber 22 through the water inlet nozzle 8, finally enters the inner tub 15, and the additive dissolving step is completed.

[0068] As Figure 1 and Figure 2As shown in this embodiment of the invention, a positioning device 14 is also installed at the bottom of the washing machine. The washing tub 1 can be stopped at a set position by the positioning device 14. When the washing tub 1 stops at the set position, the water inlet nozzle 8 is located directly above the water inlet chamber 22. The positioning device 14 can drive the washing tub 1 to stop at the preset set position of the washing machine. When the washing tub 1 stops at the set position, the lower end of the water inlet nozzle 8 is directly facing the water inlet chamber 22, preventing washing water from flowing into the bottom of the washing tub 1 from the outer periphery of the water inlet 2 or other positions if it is not aligned with the water inlet 2.

[0069] Meanwhile, during the washing process, if the washing tub 1 does not remain at the set position, the washing machine will continue to work. The water intake method is similar to existing technology, with washing water being sprayed directly into the washing tub 1 through the water inlet nozzle 8.

[0070] Example 3

[0071] like Figure 4 As shown in the embodiment of the present invention, a control method for a washing machine is introduced. This control method is applied to the washing machine described in the above embodiment. When the washing machine is filling with water, the washing tub 1 is stopped at a set position. The water inlet channel 3 is connected to the water inlet nozzle 8, and the washing water flows directly to the bottom of the washing tub 1 through the water inlet nozzle 8 and the water inlet channel 3. The purpose of setting the set position is to allow the water inlet nozzle 8 to spray the washing water more accurately into the water inlet chamber 22. When the washing machine is filling with water, the washing tub 1 stops at the set position, and the water inlet nozzle 8 faces the water inlet chamber 22 or the baffle 13. The external washing water passes through the water inlet pipe 5 and the water inlet hose 7, dissolving the detergent in the detergent box 10. The detergent is then sprayed through the water inlet nozzle 8 onto the water inlet chamber 22 or the baffle 13, and collected in the water inlet channel 3, flowing into the bottom of the washing tub 1.

[0072] In this embodiment of the invention, the washing machine has a silent water intake mode and a normal water intake mode. When the silent water intake mode is executed, the washing tub 1 stops rotating to a set position, and the water inlet channel 3 provided on the tub wall of the washing tub 1 is connected to the water inlet nozzle 8. The washing water flows through the water inlet nozzle 8 and the water inlet channel 3 to the bottom of the washing tub 1. When the normal water intake mode is executed, the washing tub 1 stops rotating to a non-set position or rotates at a set rotation-to-stop ratio. The washing water flows through the water inlet nozzle 8 and is sprayed directly into the washing tub 1 from the top opening of the washing tub 1. When the washing machine is operating, if the silent water intake mode is activated, the washing machine will determine the position of the washing tub 1 during the water intake program. It will determine whether the washing tub 1 is in the set position. When the washing tub 1 is in the set position, the water inlet nozzle 8 is directly facing the water inlet chamber 22, so that the water inlet nozzle 8 can directly spray the washing water into the water inlet chamber 22. Alternatively, the water inlet nozzle 8 is directly facing the baffle 13, and the baffle 13 collects the washing water at the water inlet channel 3, thereby enabling the washing water to enter from the bottom of the washing tub 1 and preventing the water inlet nozzle 8 from spraying the washing water around the washing tub 1. When the washing machine detects that the washing tub 1 is not in the set position before water intake, it will drive the washing tub 1 to rotate to the set position to prepare for the water intake process.

[0073] When the washing machine is in normal water intake mode, the washing tub 1 will stay in a non-set position. At this time, the water inlet nozzle 8 is misaligned with the water inlet chamber 22 or the baffle 13, and the water inlet nozzle 8 will spray washing water directly into the washing tub 1.

[0074] Example 4

[0075] like Figure 3 As shown in the figure, an embodiment of the present invention introduces a washing machine. The washing machine in this embodiment differs from the washing machine in the above embodiment in that it includes a housing 11, and a coaxial inner tub 15 and an outer tub 16 are provided inside the housing 11. A water inlet channel 3 is provided on the inner peripheral wall of the outer tub 16, and a water inlet nozzle 8 is provided in the control panel 12. The water inlet nozzle 8 is fixedly connected to the water inlet channel 3. Since the outer tub 16 does not rotate, the fixed connection between the water inlet nozzle 8 and the water inlet channel 3 in this embodiment of the present invention can make the relationship between the water inlet nozzle 8 and the water inlet channel 3 more stable, and external washing water can enter the water inlet channel 3 through the water inlet nozzle 8.

[0076] The water inlet channel 3 extends downward along the inner circumferential wall of the outer tub 16 and connects to the bottom of the inner tub 15. The external washing water is controlled by the solenoid valve 6 to control the water flow rate and passes through the water inlet pipe 5, water inlet hose 7, detergent box 10, water inlet nozzle 8, water inlet chamber 22, and water inlet channel 3 in sequence, and finally flows into the bottom of the inner tub 15.
