DETAILED DESCRIPTION

[0028] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0029] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0030] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0031] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0032] At present, common drum washing machines need to add water multiple times to mix detergent or washing powder and perform multiple rinses to achieve the purpose of washing clothes. For some clothes that are only partially dirty, if multiple rinses are performed as in the existing washing method, more water and time will be used, which is not economical and the user experience is poor. To solve this problem, the present application proposes a drum washing machine.

[0033] For ease of understanding, when the drum washing machine is placed upright on the ground, the side facing the user and operated by the user is the front direction of the drum washing machine, and the side facing away from the user is the rear direction of the drum washing machine.

[0034] Figure 1 A schematic structural diagram of a drum washing machine according to some embodiments is shown. Figure 2 A front schematic diagram of a drum washing machine according to some embodiments is shown.

[0035] See also Figure 1 to Figure 2A drum washing machine includes a housing 1, a drum 2, a detergent dispensing assembly 3, a controller and a detection member 4. The housing 1 is in a cylindrical shape extending up and down, and is rectangular as a whole. Of course, it can also be in other shapes, such as a circle, which is not limited here. A base is provided at the bottom of the housing 1, and the base supports the housing 1. The base is equipped with downwardly protruding feet and other parts in contact with the ground, so that there is a certain gap between the base as a whole and the ground.

[0036] The drum 2 is rotatably arranged in the housing 1, and a washing cavity is formed inside the drum 2. When washing clothes, the clothes are placed in the washing cavity for washing clothes. Specifically, the drum 2 includes an outer drum arranged in the housing 1 and an inner drum arranged in the outer drum. The inner drum is rotatable relative to the outer drum. There is a certain interval between the inner drum and the outer drum to form a water-containing cavity. A water hole connected to the water-containing cavity is provided on the inner peripheral wall of the inner drum. A drain port is provided at the bottom of the outer drum. The inner drum can discharge washing water to the outer drum through the water hole. The washing water is discharged from the washing machine through the drain pipe assembly connected to the drain port at the bottom of the outer drum. The internal cavity of the inner drum constitutes the washing cavity. In this embodiment, the drum 2 and the housing 1 are opened at the front side thereof, and the rotation axis of the drum 2 is arranged in the horizontal direction.

[0037] In this embodiment, a front panel 11 is provided on the front side wall of the housing 1, and a clothing inlet is provided on the front panel 11, and the clothing inlet is communicated with the inside of the drum 2. A door 13 is also hinged on the front panel 11, and the door 13 is used to close the clothing inlet. When the door 13 is opened, the user can put the clothing from the clothing inlet into the drum 2, specifically, the washing chamber in the inner drum for washing. When the door 13 is closed, the washing machine can be in the washing program.

[0038] Figure 3 A schematic structural diagram of a main control board of a drum washing machine according to some embodiments is shown. Figure 4 A structural schematic diagram of a main control panel of a drum washing machine according to some embodiments is shown from another perspective.

[0039] See also Figure 3 Figure 4 In this embodiment, a main control panel 12 is further provided on the top of the front panel 11. The main control panel 12 is used to set control buttons so that the user can select different washing programs to control the washing machine. A control knob 121 is also provided on the main control panel 12, which is used to control the washing time or water intake by rotating to different scales. The control knob 121 is located in the middle of the main control panel 12. A soap box 122 is provided at one end of the main control panel 12. The soap box 122 stores laundry liquid or laundry powder, which can be automatically added to the inner drum to avoid manual addition by the user, thereby improving user convenience.

[0040] In this embodiment, a mounting hole 123 is provided on the front side wall of the box 1. The mounting hole 123 can be specifically located on the main control board 12, especially at one end of the main control board 12. The mounting hole 123 and the soap box 122 can be located on both sides of the control knob 121, respectively. It is understandable that the mounting hole 123 is arranged at one end of the main control board 12, and can be arranged offset with the barrel 2. When the mounting hole 123 extends toward the rear of the box 1, it is located in the interval between the barrel 2 and the box 1, so as to avoid interference with the barrel 2. Among them, since the barrel 2 is usually cylindrical, and the box 1 is usually a rectangular box, when the barrel 2 is placed in the box, the upper left corner and the upper right corner of the box 1 do not overlap with the barrel 2 in the front-to-back direction of the box 1, so that the mounting hole 123 is arranged at one end of the main control board 12, it can be just located in the interval between the barrel 2 and the box 1, which is convenient for the subsequent installation of the detergent dispensing component 3.

[0041] In this embodiment, the detergent delivery assembly 3 can be pulled out and arranged in the mounting hole 123, and the detergent delivery assembly 3 has a spray head 33, and the spray head 33 is used to spray detergent to the clothes to be washed in the sensing area 41, and the sensing area 41 is located outside the mounting hole 123. Therefore, the spray head 33 can be used to spray the detergent onto the clothes to be washed, especially the local dirty parts of the clothes to be washed, such as the local dirty parts of the down jacket, by spraying the water-free detergent, so that the local dirty parts are covered with detergent, and the detergent can be put into the inner drum, and the clothes such as the down jacket are driven to rotate by the inner drum, and the dirt is removed by means of high temperature, so that the clothes are washed, the water consumption is reduced, and the washing time is saved. It is understandable that the detergent can also be other, such as dry cleaning detergent, foam detergent, etc., which are sprayed to the local dirty parts of the clothes through the spray head 33 and attached to them.

[0042] In the present embodiment, the detection member 4 is arranged on the housing 1, and is configured to generate a first signal when it is detected that the clothes to be washed are located in the sensing area 41, and transmit the first signal to the controller (not shown in the figure), the controller is arranged on the housing 1, and is respectively communicated with the detergent delivery component 3 and the detection member 4. When the controller receives the first signal, the controller controls the spray head 33 to spray detergent to the clothes to be washed. It is understandable that the local dirty parts of the clothes to be washed can be placed in the sensing area 41, so that the detergent can be automatically delivered to the local dirty parts in a targeted manner, thereby improving the level of automation and enhancing the user experience. Among them, the controller may include a programmable logic control component, a memory, and an electronic component connected to the programmable logic control component, etc., which is arranged on the main control board 12. In some embodiments, the controller may be the control center of the washing machine, or it may be used alone to control the detergent delivery component to deliver detergent.

[0043] It can be understood that the first signal is a signal for delivering detergent. After receiving the first signal, the controller can control the spray head 33 to spray detergent to a local position of the clothes to be washed. When the detection element 4 cannot detect the clothes to be washed in the sensing area 41, a second signal can be generated. After receiving the second signal, the controller can control the spray head to immediately stop spraying detergent.

[0044] Figure 5 A schematic structural diagram of a detergent dispensing assembly of a drum washing machine according to some embodiments is shown. Figure 6 A schematic structural diagram of a detergent dispensing assembly of a drum washing machine according to some embodiments is shown from another perspective.

[0045] Among them, continue to see Figure 5 and Figure 6 The detergent dispensing assembly 3 includes a storage portion 31 and an injection portion 32. The storage portion 31 has a cavity for storing detergent. The injection portion 32 is connected to the cavity and the injection head 33, and is used to extract the detergent in the cavity and spray it onto the clothes to be washed through the injection head 33. Since the detergent dispensing assembly 3 can be pulled out and arranged in the mounting hole 123, when the detergent in the storage portion 31 is exhausted, it can be pulled out as a whole and refilled, which is convenient for long-term use. It is understandable that the storage portion 31 is provided with a closable opening, and the opening is connected to the cavity, so that after the opening is opened, the detergent can be poured into the cavity, and the opening can be closed after the filling is completed.

[0046] Furthermore, the detergent delivery assembly 3 also includes a support box 34, the upper portion of which is open to form a mounting cavity, the storage portion 31 and the injection portion 32 are clamped in the mounting cavity, and the support box 34 can be pulled out and arranged in the mounting hole 123, so that when the detergent needs to be filled, the support box 34 can be pulled out, and then the storage portion 31 is removed from the support box 34 and refilled, which has a certain protective effect on the storage portion 31 and the injection portion 32. Of course, the storage portion 31 and the injection portion 32 can be hard-connected so as to be directly pullable and arranged in the mounting hole 123. It is understandable that in order to avoid interference between the support box 34 and the barrel 2, after the support box 34 is installed in place in the mounting hole 123, there should be a certain distance between it and the barrel 2.

[0047] Among them, the support box 34 can be a rectangular box as a whole, and the mounting hole 123 is a rectangular hole that matches it. In this way, when the support box 34 is installed in the mounting hole, it can use its own rectangular shape to limit it to prevent it from turning over. At the same time, the support box 34 should be slightly smaller than the aperture of the mounting hole 123 to facilitate the user to pull out the support box 34. After being installed in place, the support box 34 is supported on the bottom wall of the mounting hole 123.

[0048] Furthermore, the storage part 31 and the spray part 32 are arranged side by side in the support box 34 along the front-to-back direction of the box body 1, thereby utilizing the front-to-back depth of the box body 1, saving space, and avoiding the installation hole 123 from being too large to affect the structure of the main control board 12. The spray part 32 includes a pumping pump, the inlet of the pumping pump is connected to the cavity, and the outlet of the pumping pump is connected to the spray head 33 through a connecting pipe 35, so that the detergent is extracted by the pumping capacity of the pumping pump and sprayed onto the local dirty parts of the clothes to be washed with a certain pressure.

[0049] The pumping pump is electrically connected to the controller and is controlled by the controller. For example, after the controller receives the first signal, it controls the pumping pump to work. It is understandable that when the laundry is away from the sensing area 41 until it is not in the sensing area 41, the detection element 4 cannot detect the laundry, and at this time, the second signal is generated, and the controller controls the pumping pump to stop working. Of course, in some embodiments, timing operations can also be performed. For example, after the controller receives the first signal, it controls the pumping pump to work for a preset time. After the preset time is exceeded, the pumping pump is controlled to stop working. In this embodiment, the preset time can be set to 4s.

[0050] It is understandable that the injection portion 32 may further include a shell, and the pumping pump is disposed in the shell. The shell protects the pumping pump and prevents it from being exposed.

[0051] In some embodiments, the cleaning agent delivery assembly 3 further includes a decorative plate 36, which is connected to one end of the support box 34 away from the barrel 2. The size of the decorative plate 36 matches the size of the mounting hole 123, so that when the support box 34 is installed in place, the decorative plate 36 is located at the front end of the support box 34 to close the mounting hole 123 and improve the aesthetics of the main control board 12. The spray head 33 is arranged on the decorative plate 36. Specifically, a clamping hole may be provided on the decorative plate 36. The spray head 33 is clamped on the clamping hole, one end of which is connected to the connecting pipe 35, and the other end extends out of the clamping hole for cleaning agent spraying. In order to expand the spraying area of ​​the spray head 33, the inner diameter of the spray head 33 gradually increases along the spraying direction to form a conical structure.

[0052] In some embodiments, when the cleaning agent dispensing assembly 3 is installed in place in the installation hole 123, the decorative panel 36 is flush with the outer wall of the main control panel 12, thereby further improving the aesthetics of the main control panel 12 and avoiding the formation of an uneven structure that affects the user experience.

[0053] In some embodiments, see Figure 8, a step 124 is provided on the outer edge of the mounting hole 123. When the detergent dispensing assembly 3 is installed in place in the mounting hole 123, the support box 34 is supported on the bottom wall of the mounting hole 123, and the edge of the decorative plate 36 abuts on the step portion 124, thereby limiting the support box 34 from continuing to move toward the rear side of the box body 1, so as to limit the position of the detergent dispensing assembly 3 in the mounting hole 123. It can be understood that when the edge of the decorative plate 36 abuts on the step portion 124, the thickness of the decorative plate 36 is adapted to the extension length of the step portion 124 in the front-to-back direction, so that the outer wall surface of the decorative plate 36 can be flush with the outer wall of the main control board 12, and the projection of the support box 34 in the front-to-back direction should be inside the decorative plate 36, and there is a certain distance between the outer edge of the support box 34 away from the end of the cylinder 2 and the outer edge of the decorative plate 36, so that the decorative plate 36 can abut on the step portion, and the support box 34 can extend into the mounting hole.

[0054] In some embodiments, the detection member 4 is disposed on the decorative plate 36, so that it is convenient to be integrally disposed with the detergent delivery assembly 3. The detection member 4 is located on the side of the spray head 33 close to the bottom of the box body 1. After it detects that the laundry to be washed is approaching, the detergent sprayed by the spray head 33 is convenient to reach the laundry to be washed according to its inertia, and the spray head 33 sprays the detergent obliquely downward. Of course, the detection member 4 can also be located on the upper side of the spray head 33, and the spray head 33 sprays the detergent obliquely upward.

[0055] In some embodiments, the detection member 4 includes a distance sensor, and the sensing area 41 is located on the side of the detection end of the distance sensor away from the front side wall of the box body 1, and the boundary of the sensing area 41 is located within the detection area of ​​the distance sensor, so that when the clothes to be washed are close to the distance sensor and enter the sensing area 41, they can be detected by the distance sensor, thereby sending a first signal to the controller. The distance sensor can be a photoelectric type, and the detection end detects whether there is an obstruction within a certain distance from its front end to make a judgment. In this embodiment, the detection distance of the distance sensor is 10mm. When the clothes are within 10mm of the detection end of the distance sensor, it can be determined that the clothes are in the sensing area 41.

[0056] It can be understood that the sensing area 41 is a virtual space area located on the side of the detection end of the distance sensor away from the front side wall of the box 1, and its boundary is within the boundary of the detection area that can be detected by the detection end of the distance sensor. The specific range and shape can be determined according to the performance indicators of the distance sensor and the settings of technicians, and are not limited here.

[0057] Figure 7 A partial structural schematic diagram of a detergent dispensing assembly of a drum washing machine according to some embodiments is shown. Figure 8 A state diagram showing a drum washing machine when a support box is pulled out from a main control panel according to some embodiments is shown.

[0058] Continue to see Figure 7 and Figure 8 In some embodiments, a press-rebound mechanism is also connected to the decorative plate 36. By setting the press-rebound mechanism, when the support box 34 is installed in place, the decorative plate 36 is pressed toward the rear end of the box body 1, so that the decorative plate 36 is locked with the inner wall of the mounting hole 123, thereby fixing the detergent dispensing component 3. When the support box 34 needs to be pulled out to refill the detergent, the decorative plate 36 is pressed toward the rear end of the box body 1 again, so that the decorative plate 36 and the mounting hole 123 are unlocked, and the support rod pops out of the mounting hole 123, which is convenient for the user to take out the detergent dispensing component 3. Among them, the press-rebound mechanism may include a locking pin 51 and a claw 52. The locking pin 51 is arranged on the inner side surface of the decorative panel 36, and the claw 52 is arranged on the inner wall of the mounting hole 123. The rear end of the claw 52 is connected to the elastic member. When the support box 34 is installed in place, the locking pin 51 is just wrapped and locked by the claw 52. When the support box 34 needs to be popped out, the decorative panel 36 is pressed toward the rear end of the box body 1, so that the elastic member drives the claw 52 to release the lock with the locking pin 51, and the support box 34 is popped out of the mounting hole 123.

[0059] To sum up, in this embodiment, by setting up a detergent delivery component 3 and a detection component 4, when the clothes to be washed enter the sensing area 41, the detection component 4 detects the clothes to be washed, and the controller controls the spray head 33 of the detergent delivery component 3 to spray detergent toward the local dirty parts of the clothes to be washed to clean the local parts. The clothes after spraying can be put into the drum, rotated and subjected to high-temperature treatment to remove the dirt, thereby reducing the amount of water used for washing clothes and reducing the washing time. The user experience is improved by cleaning the local dirt on the clothes. Compared with the method of solving the problem of washing local dirt on the clothes by setting up an ultrasonic washing component, the structure is simpler, has a lower cost, and is conducive to promotion.
