Description

Technical Field

[0001] The present invention relates to the field of washing equipment, and particularly to a drum washing machine and a method for discharging washing agents thereof. Background Art

[0002] With the improvement of people's living standards, washing equipment such as washing machines and dishwashers has entered people's daily lives; taking the drum washing machine as an example, the drum washing machine performs cleaning by putting washing agents, washing water, and laundry to be washed into the drum and rotating it around a horizontal axis. The drum has a plurality of rolling bars formed thereon, so that the clothes are lifted by the rolling bars and then dropped to impact and rub, thereby cleaning the clothes.

[0003] Among them, the washing machine door body is a common accessory of a drum washing machine, which is used to prevent the water in the drum from overflowing and is convenient for users to understand the operating state of the washing machine at any time. For the traditional drum washing machine door body, it generally only has the functions of an observation window and sealing water. A separate detergent discharge box needs to be designed inside the washing machine to achieve the discharge of washing agents. Such a design not only complicates the structure of the drum washing machine, prolongs the production cycle, and increases the production cost, but also is not conducive to the maintenance of the drum washing machine and is inconvenient for users' daily use. Problems such as foam overflow and water overflow from the front when the water pressure changes may occur during use, and problems such as residue and insufficient dissolution of detergents such as washing powder and laundry detergent may also occur.

[0004] To solve the above problems, during the early research process, the applicant successively submitted a patent application with the application number CN201510123069.8 and a patent application with the application number CN201820452028.2. The structure is as Figure 1 shown, that is, at least one discharge cavity is provided on the door glass of the drum washing machine door body for containing washing agents. At the same time, the outlet of the water supply pipeline is matched with the discharge cavity to discharge clean water into the discharge cavity. A discharge unit including a siphon tube and a siphon cover is provided in the discharge cavity, so that the washing agent diluted by clean water can be discharged from the discharge cavity; this structure combines the washing agent control device with the door glass, without the need to separately set a control device in the drum washing machine. While ensuring the discharge of washing agents, it simplifies the internal structure of the washing machine and reduces the overall production cost of the washing machine;

[0005] However, the applicant recently conducted further research on this structure and found that when the detergent diluted with clear water was discharged in the early solution, due to the setting of the siphon device, although it could achieve a relatively smooth discharge function, after the discharge ended, a certain amount of liquid often accumulated in the discharge chamber, making it impossible to completely discharge the substances in the discharge chamber. When the washing was over and the washing machine was idle for a period of time, on the one hand, bacteria were likely to grow in the discharge chamber, which was not conducive to ensuring the hygiene inside the washing machine. On the other hand, when the liquid in the discharge chamber evaporated naturally, white scaling often occurred in the discharge chamber. Since the discharge chamber could be directly observed from the outside of the door glass, it seriously affected the appearance of the washing machine and the cleanliness inside the washing machine. Summary of the Invention

[0006] In view of this, the present invention aims to provide a drum washing machine and a method for discharging detergent to solve the problem in the prior art that the substances in the discharge chamber cannot be completely discharged by using the siphon structure.

[0047] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0048] Embodiment 1

[0049] This embodiment is directed to a detergent control device for a drum washing machine. Similar to the drum washing machine in the prior art, the drum washing machine includes an inner drum 3, an outer drum 4, and a door body 1. The inner drum 3 is rotatably disposed inside the outer drum 4, the door body 1 is connected to the outer drum 4, and a receiving cavity 21 and a discharge cavity 22 are respectively provided on the door glass 11 of the door body 1. The receiving cavity 21 communicates with the discharge cavity 22.

[0050] In the prior art and in the early research process of the applicant, a siphon device was provided in the receiving cavity 21. The receiving cavity 21 communicates with the discharge cavity 22 through the siphon device. The detergent and washing water are discharged from the receiving cavity 21 into the inner drum 3 through the siphon device and the discharge cavity 22 in sequence. This structure combines the detergent control device with the door glass, eliminating the need to separately provide a control device in the drum washing machine. While ensuring the discharge of the detergent, it simplifies the internal structure of the washing machine and reduces the overall production cost of the washing machine. However, although this structure can achieve a relatively smooth discharge function, due to the setting of the siphon device, a certain amount of liquid often accumulates in the discharge cavity after the discharge ends, making it impossible to completely discharge the substances in the discharge cavity. When the washing machine is idle after the laundry is finished, on the one hand, bacteria are likely to breed in the discharge cavity, which is not conducive to ensuring the hygiene inside the washing machine. On the other hand, when the liquid in the discharge cavity naturally volatilizes, white scaling often appears in the discharge cavity. Since the discharge cavity can be directly observed from the outside of the door glass, it seriously affects the appearance of the washing machine and the cleanliness inside the washing machine.

[0051] In order to solve the problem that in the prior art, the siphon structure cannot completely discharge the substances in the discharge cavity, this embodiment provides a drum washing machine and a method for discharging washing agents, as shown in the attached Figure 2-3 figure. The drum washing machine includes a door body 1, an inner drum 3, and an outer drum 4. The inner drum 3 is disposed inside the outer drum 4. The door body 1 cooperates with the outer drum 4. A cavity 2 is provided on the door glass 11 of the door body 1 for accommodating washing agents or washing water. A discharge opening 24 is provided on the cavity 2. The cavity 2 communicates with the inner drum 3 through the discharge opening 24, so that the washing agents or washing water in the cavity 2 can directly enter the inner drum 3 through the discharge opening 24. In addition, the drum washing machine further includes a control device 5. The control device 5 includes a fixed part 51 and a movable part 52. The fixed part 51 is fixedly connected to the outer drum 4 or the door seal. The movable part 52 is disposed inside the cavity 2 in a movable manner. The fixed part 51 cooperates with the movable part 52, and the movable part 52 cooperates with the discharge opening 24 to block or open the discharge opening 24 by the movable part 52.

[0052] Thus, when the movable part 52 blocks the discharge opening 24, a user or the washing machine can discharge washing agents into the cavity 2. After the door body 1 is completely closed, when starting to wash clothes or when it is necessary to discharge washing agents, the washing machine intakes water into the cavity 2 through the water inlet 6 to dilute the washing agents. At the same time, the fixed part 51 and the movable part 52 cooperate to cause the movable part 52 to displace inside the cavity 2 and open the discharge opening 24, thereby realizing the discharge of the washing agents and the washing water.

[0053] In this embodiment, the cavity 2 directly communicates with the inner drum 3 through the discharge opening 24. There is no need to provide a siphon structure. Only by providing the fixed part 51 and the movable part 52 and through their cooperation, the blocking or opening of the discharge opening 24 can be realized. On the one hand, it can conveniently and quickly discharge the washing agents and can completely discharge the substances in the cavity 2, which is beneficial to ensuring the hygiene and cleanliness inside the washing machine and is beneficial to maintaining the good appearance of the washing machine. On the other hand, based on the design concept of combining the washing agent control device with the door glass, the internal structure of the washing machine can be further simplified, and the production cost of the whole washing machine can be reduced.

[0054] In addition, it should be noted that in this embodiment, and even in the present invention, the term "washing agent" refers to washing products such as washing powder, bleach, fabric softener, detergent, bleach, etc. that can be purchased on the market. Since they are all prior art, no further description will be given.

[0055] Embodiment 2

[0056] As shown in the attached Figure 2-3As shown in the figure, this embodiment is further introduced on the basis of Embodiment 1. The cavity 2 includes a material storage cavity 21 and a discharge cavity 22. A discharge hole 23 is provided on the first bottom wall 211 of the material storage cavity 21. The discharge cavity 22 is arranged below the first bottom wall 211. The material storage cavity 21 communicates with the discharge cavity 22 through the discharge hole 23. A discharge opening 24 is provided at one end of the discharge cavity 22 close to the inner cylinder 3. The fixing part 51 displaces the movable part 52 through electromagnetic force or mechanical force. The movable part 52 at least includes a movable door 521. The movable door 521 is connected to the first bottom wall 211 in a movable manner. The movable door 521 cooperates with the discharge opening 24, and the bottom of the movable door 521 cooperates with the second bottom wall 221 of the discharge cavity 22.

[0057] When no force is generated between the fixing part 51 and the movable part 52, the bottom of the movable door 521 fits against the second bottom wall 221 to block the discharge opening 24. At this time, detergent can be discharged into the material storage cavity 21, or an appropriate amount of washing water can be continuously discharged to dilute the detergent. When a force is generated between the fixing part 51 and the movable part 52, the movable door 521 moves relative to the first bottom wall 211 and the second bottom wall 221, so that a gap or channel is formed between the bottom of the movable door 521 and the second bottom wall 221, that is, the discharge opening 24 is opened. At this time, washing water can be discharged into the material storage cavity 21. Driven by the water flow, the detergent flows from the material storage cavity 21 through the discharge hole 23, the discharge cavity 22, and the discharge opening 24 in sequence and enters the inner cylinder 3, thereby realizing the discharge of the detergent and the washing water.

[0058] To ensure that the materials in the cavity 2 can be discharged fully and completely, the first bottom wall 211 and the second bottom wall 221 are further introduced in this embodiment. A concave groove 212 is provided on the first bottom wall 211. The discharge hole 23 penetrating the concave groove 212 is provided in the concave groove 212, so that the materials in the material storage cavity 21 can be gathered at the concave groove 212 and completely flow into the discharge cavity 22 through the discharge hole 23. The second bottom wall 221 is inclined downward, that is, the discharge opening 24 is an opening expanding toward the inner cylinder 3, which is convenient for the materials to pour into the inner cylinder 3, so that the materials flowing into the discharge cavity 22 can completely flow into the inner cylinder 3. Through the relevant structures of the first bottom wall 211 and the second bottom wall 221, it is beneficial to ensure that the materials completely flow from the cavity 2 into the inner cylinder 3 and avoid the situation of materials accumulating in the cavity 2.

[0059] Furthermore, the first bottom wall is an inclined surface, and the discharge hole is located at the lowest end of the inclined surface. Such a structure can make the detergent water drain more thoroughly and avoid residue.

[0060] Further, the second bottom wall of the discharge cavity is inclined from one side corresponding to the discharge hole to the other side. Such a structure can make the detergent water drain more thoroughly and avoid residue.

[0061] The inclination angles of the first bottom wall 211 and the second bottom wall 221 are 1° to 10°, preferably 2° to 6°.

[0062] In addition, on the basis of the above structure, this embodiment further provides a method for discharging detergent in a drum washing machine, including:

[0063] S1. Discharge the detergent into the cavity 2;

[0064] Among them, when discharging the detergent into the cavity 2, the fixing part 51 does not exert a force on the movable part 52, that is, the movable part 52 blocks the discharge opening 24.

[0065] S2. The fixing part 51 exerts a force on the movable part 52;

[0066] Among them, by controlling the fixing part 51 to exert a force on the movable part 52, the movable part 52 generates a displacement relative to the first bottom wall 211 and the second bottom wall 221, so that a gap or channel is formed between the movable part 52 and the second bottom wall 221, that is, the discharge opening 24 is opened.

[0067] S3. Discharge washing water into the cavity 2.

[0068] Discharging washing water into the cavity 2 can, on the one hand, dilute the detergent in the cavity 2, and on the other hand, the water flow can drive the detergent to flow through the discharge opening 24 from the cavity 2 and be put into the inner tub 3.

[0069] Embodiment 3

[0070] As shown in the appendix Figure 3-4 On the premise that the relevant structures are the same as those in Embodiment 1 or Embodiment 2, the fixing part 51 and the movable part 52 are specifically introduced in this embodiment;

[0071] Among them, the fixing part 51 displaces the movable part 52 through electromagnetic force. The fixing part 51 is an electromagnetic device 511, preferably an electromagnet, an electromagnetic coil, etc. The movable part 52 includes a movable door 521. The movable door 521 cooperates with the electromagnetic device 511, and at least part of the structure of the movable door 521 is made of ferromagnetic materials such as iron, cobalt, nickel, etc.; the movable door 521 is connected to the first bottom wall 211 in a manner that can move in the vertical direction.

[0072] As shown in the appendix Figure 3As shown, when the door body 1 is opened, or when the door body 1 is closed and the electromagnetic device 511 is not powered on, the bottom of the movable door 521 is in contact with the second bottom wall 221 to block the discharge opening 24; as shown in the appendix Figure 4 As shown, when the door body 1 is completely closed and the electromagnetic device 511 is powered on, the electromagnetic device 511 generates an electromagnetic suction force to move the movable door 521 upward, so that a gap or channel is formed between the bottom of the movable door 521 and the second bottom wall 221 to discharge the washing agent and washing water. After that, if the power supply of the electromagnetic device 511 ends, the movable door 521 moves downward under the action of its own gravity until the bottom of the movable door 521 is in contact with the second bottom wall 221, and the discharge opening 24 is blocked again.

[0073] In addition, on the basis of the above structure, this embodiment also provides a method for discharging the washing agent of a drum washing machine, including:

[0074] S1. Discharge the washing agent into the material storage cavity 21;

[0075] Among them, it can be that the user opens the door body 1 to manually discharge the washing agent into the material storage cavity 21, or the washing machine automatically discharges the washing agent into the material storage cavity 21.

[0076] S2. Judge whether the door body 1 is completely closed. If so, go to step S3;

[0077] When the door body 1 is completely closed, subsequent feeding operations can be carried out; when the door body 1 is not completely closed, preferably, the washing machine continuously sends a reminder to the user to prompt the user to close the door body 1.

[0078] S3. Discharge a specified amount of washing water into the material storage cavity 21 through the water inlet 6;

[0079] At this time, discharging a specified amount of washing water is beneficial to diluting the washing agent.

[0080] S4. The electromagnetic device 511 is powered on;

[0081] When the electromagnetic device 511 is powered on, it generates an electromagnetic suction force to move the movable door 521 upward, so that a gap or channel is formed between the bottom of the movable door 521 and the second bottom wall 221, and the discharge opening 24 is opened, so that the substances in the material storage cavity 21 and the discharge cavity 22 enter the inner cylinder 3 through the discharge opening 24.

[0082] S5. Continue to discharge a specified amount of washing water into the material storage cavity 21;

[0083] At this time, the continuously discharged washing water can, on the one hand, flush the material storage cavity 21 and the discharge cavity 22, drive the remaining washing agent into the inner cylinder 3, and on the other hand, continue to supply water into the inner cylinder 3 until the amount of water required for washing is met.

[0084] When S6 and the water inlet 6 are closed and after the elapse of the preset duration, the electromagnetic device 511 is de-energized.

[0085] Consequently, the electromagnetic device 511 does not generate electromagnetic suction force, and the movable door 521 moves downward under the action of its own gravity until the bottom of the movable door 521 abuts against the second bottom wall 221 to block the discharge opening 24.

[0086] Embodiment 4

[0087] As shown in the attached Figure 5-6 figures, on the premise that the relevant structures in this embodiment are the same as those in Embodiment 1 or Embodiment 2, the fixed part 51 and the movable part 52 are specifically introduced;

[0088] The fixed part 51 displaces the movable part 52 by mechanical force. The fixed part 51 includes a fixing plate 512 and a lifting arm 513. One end of the fixing plate 512 is fixedly connected to the outer cylinder 4 or the door seal, the other end of the fixing plate 512 is connected to the lifting arm 513, and the lifting arm 513 extends away from the inner cylinder 3; the movable part 52 includes a movable door 521, and a movable arm 522 is arranged on the side of the movable door 521 close to the inner cylinder 3, and the movable arm 522 cooperates with the lifting arm 513; meanwhile, the movable part 52 is connected to the first bottom wall 211 in a manner that it can move in the vertical direction.

[0089] When the door body 1 is not closed, the movable arm 522 and the lifting arm 513 are disengaged from each other, and the bottom of the movable door 521 abuts against the second bottom wall 221 to block the discharge opening 24; when the door body 1 is completely closed, the movable arm 522 is engaged with the lifting arm 513, and the lifting arm 513 lifts the movable arm 522. At the same time, the movable door 521 is lifted, so that a gap or passage is formed between the bottom of the movable door 521 and the second bottom wall 221, that is, the discharge opening 24 is opened; after the laundry is finished and the door body 1 is opened, the engagement relationship between the movable arm 522 and the lifting arm 513 is released, that is, the movable arm 522 and the lifting arm 513 return to the disengaged state from each other, and the movable part 52 moves downward under the action of its own gravity until the bottom of the movable door 521 abuts against the second bottom wall 221, thereby blocking the discharge opening 24 again.

[0090] To facilitate the movement of the movable arm 522, a transition surface 514 is provided at the end of the lifting arm 513 away from the inner cylinder 3, so that during the closing process of the door body 1, the movable arm 522 can smoothly engage with the lifting arm 513 along the transition surface 514; at the same time, a cross-section matching the transition surface 514 can also be provided on the movable arm 522, so that the movable arm 522 and the lifting arm 513 can cooperate more smoothly.

[0091] Example 5

[0092] As shown in the Figure 7-8 accompanying drawings, on the premise that the relevant structures in this embodiment are the same as those in Embodiment 1 or Embodiment 2, the fixed part 51 and the movable part 52 will be specifically introduced;

[0093] The fixed part 51 rotates the movable part 52 by mechanical force. The fixed part 51 includes a fixed plate 512 and a first ejector pin 515.
