Description

Technical Field

[0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine. Background Art

[0002] A washing machine is a household appliance that uses mechanical energy to drive water flow to wash clothes and other fabrics. According to the rotation method, there are fully automatic washing machines with pulsator rotation and drum washing machines. Since the drum washing machine has a side-opening door, it is impossible to open the door to add detergents during washing, so it is necessary to add laundry detergent, softener and other detergents from the outside and flush them into the drum through the water. For a typical fully automatic pulsator washing machine, since the door cover is set at the top and can be paused and opened during washing, the requirements for detergent placement are not high.

[0003] The basic structure of a fully automatic pulsator washing machine is as follows: it has a rectangular box with a rotating washing tub inside for accommodating clothes; a pulsator is provided at the bottom of the washing tub, and the pulsator is driven to rotate by a power system, which includes an electric motor and a clutch system; a control panel seat is provided on the top of the box, and an openable door cover is provided on the control panel seat.

[0004] The detergent box of the existing fully automatic washing machine is set inside the control panel seat or at the rear of the control panel seat, but this traditional design brings many defects and inconveniences: when the current detergent box is filled with water into the outer barrel, the water injection port must be located outside the clothing input port, and the water injection port is close to the outer barrel cover. When the water pressure is low, the "water hook" phenomenon often occurs, causing part of the water to flow to the outside of the outer barrel, causing inconvenience and even safety problems. In addition, when the detergent box is set inside the control panel seat, it can be pulled out and set in the control panel seat at the rear side of the clothing input port. The side of the control panel seat corresponding to the clothing input port is provided with an opening, and the detergent box is set in the opening; each time the clothes are washed, the detergent box must be pulled out and then the detergent is added, which is very troublesome for the user to use. If detergents such as softeners are added when the washing machine has started working, it will be even more inconvenient; when the detergent box is set behind the control panel seat, due to the distance from the user, adding detergent requires the user to stretch his arm, which is inconvenient to use and affects the appearance. In addition, manual detergent addition, too much or too little will affect the washing effect of the clothes.

[0005] However, with the improvement of automation level, the requirements for intelligent, environmentally friendly and healthy home appliances are getting higher and higher, which puts forward requirements for intelligent and automatic dispensing of fully automatic washing machines.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0007] In view of the above-mentioned problems in the prior art, the present invention proposes a washing machine, wherein the rotating structure can realize the input of detergent and the filling of water into the outer barrel through rotation. When filling water into the outer barrel, the injection cavity can be moved inward by rotation to prevent water from flowing to the outside of the outer barrel, and the washing machine has good concealment.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0017] Furthermore, an outflow nozzle for outflow of the detergent is provided on the rotating structure, the outflow nozzle is communicated with the detergent input cavity, and the outflow nozzle is located in the middle of the rotating structure.

[0018] Furthermore, a plurality of water injection ports are provided at the lower portion of the outer end wall, which are connected to the water injection cavity and are used to allow the water in the water injection cavity to flow into the outer barrel.

[0019] Furthermore, a water injection nozzle connected to the water injection chamber and used for injecting water into the water injection chamber is provided on the rotating structure. The water injection nozzle is located in the middle of the rotating structure, and the water injection nozzle and the outflow nozzle are arranged side by side at the same height.

[0040] See also Figure 1-Figure 8 , is an embodiment of the washing machine proposed by the present invention, a washing machine comprises: a box body, an outer barrel and an inner barrel are arranged in a set arrangement in the box body, a control panel seat 10 is arranged on the top of the box body, a clothing input port 11 located above the outer barrel is arranged on the control panel seat 10, a convex receiving groove 12 is arranged at the side wall of the clothing input port 11, the side wall of the clothing input port 11 surrounds the clothing input port 11, and the clothing input port 11 is circular. A rotating structure 20 is arranged at the receiving groove 12, the rotating structure 20 is rotatably arranged in the receiving groove 12, and the rotating structure 20 can realize the input of detergent and the injection of water into the outer barrel by rotation; the rotating structure 20 is provided with a detergent input cavity 21 for inputting detergent, a water injection cavity 22 for injecting water into the outer barrel, and an inner end wall 23 matching the side wall of the clothing input port 11.

[0041] The rotating structure 20 can realize the input of detergent and the inflow of water into the outer barrel by rotating. When water is injected into the outer barrel, the injection chamber 22 can be moved inward by rotating, that is, moved in the direction close to the axis of the inner barrel, which is conducive to increasing the distance between the injection chamber 22 and the outer barrel cover, and is conducive to the water flow spraying toward the center of the inner barrel, which is conducive to the washing of the clothes in the inner barrel; and the distance between the water flow and the inner edge of the outer barrel cover is increased, so as to avoid the water flow from flowing to the outside of the outer barrel when the water pressure is unstable, thereby ensuring safety. By providing an outwardly convex receiving groove 12 at the side wall of the clothing input port 11, the rotating structure 20 is arranged in the receiving groove 12, so that the rotating structure 20 is hidden; an inner end wall 23 matching the side wall of the clothing input port 11 is provided, so that when the rotating structure 20 is in a closed state, the inner end wall 23 matches the side wall of the clothing input port 11, thereby ensuring the concealment of the rotating structure 20.

[0042] See also Figure 1-Figure 3 As shown, the rotating structure 20 has a closed state, an upward rotating state in which the detergent input chamber 21 is moved inwards and opened by rotation, and a downward rotating state in which the water injection chamber 22 is moved inwards and opened by rotation. That is, the rotating structure 20 has a closed state that matches the side wall of the clothing input port 11, and also has an upward open state and a downward open state. When detergent needs to be added, the rotating structure 20 is rotated upward to open, so that the detergent input chamber 21 moves inwards and extends into the clothing input port 11, and the rotating structure 20 is in an upward open state to achieve the input of detergent; when water needs to be injected into the outer barrel, the rotating structure 20 is rotated downward to open, so that the water injection chamber 22 moves inwards and extends into the clothing input port 11, so that the distance between the water injection chamber 22 and the outer barrel cover increases, and the rotating structure 20 is in a downward open state to complete the injection of water into the outer barrel.

[0043] The rotating structure 20 is hingedly arranged in the accommodating groove 12, and the rotating structure 20 rotates around the hinge axis 25; in order to realize the rotation of the rotating structure 20 around the hinge axis 25, the accommodating groove 12 has an arc-shaped bottom surface with the center line of the hinge axis 25 as the axis, and the distance from any point on the arc-shaped bottom surface to the center line of the hinge axis 25 is equal, ensuring that the rotating structure 20 can rotate in the accommodating groove 12 and minimizing the volume of the accommodating groove 12; preferably, the rotating structure 20 is provided with an arc-shaped outer end wall 24 with the center line of the hinge axis 25 as the axis, that is, the distance from any point on the outer end wall 24 to the center line of the hinge axis 25 is equal; providing an arc-shaped outer end wall 24 is beneficial to increasing the volume of the rotating structure 20. In order to realize that when the rotating structure 20 is in the upward open state, the detergent injection chamber 21 rotates inwardly and extends into the clothing injection port 11, and when the rotating structure 20 is in the downward open state, the water injection chamber 22 rotates inwardly and extends into the clothing injection port 11, it is necessary to set the hinge shaft 25 close to the inner end wall 23, and the distance between the hinge shaft 25 and the outer end wall 24 is greater than the distance between the hinge shaft 25 and the inner end wall 23; preferably, the distance between the hinge shaft 25 and the outer end wall 24 is 7 to 15 times greater than the distance between the hinge shaft 25 and the inner end wall 23.

[0044] See also Figure 7 and Figure 8 As shown, in order to realize the rotation of the rotating structure 20 and the positioning of the rotating structure 20 in the closed state and the two open states, the rotating structure 20 is driven by a motor 30. Since the hinge shaft 25 is close to the inner end wall 23, in order to provide space for the motor 30, a transmission 40 is provided between the motor 30 and the rotating structure 20. The transmission 40 comprises a first transmission gear 41 connected to the output shaft of the motor 30 and a second transmission gear 42 connected to the hinge shaft 25, wherein the axis of the first transmission gear 41 is located outside the axis of the second transmission gear 42, and the rotational torque of the motor 30 is transmitted to the hinge shaft 25 through the meshing of the gears, so as to drive the rotation of the rotating structure 20. By setting the motor 30, the rotation angle of the motor 30 can be set to achieve accurate positioning of the rotating structure 20, and there is no need to set a positioning structure on the driving rotating structure 20; by setting the transmission 40, the rotation axis of the torque transmission can be changed, which is beneficial to the installation space of the motor 30 and can change the transmission ratio; preferably, the transmission 40 is set as a reducer, and the diameter of the second transmission gear 42 is set to be larger than the diameter of the first transmission gear 41. The transmission 40 also has a third transmission gear 43 meshing with both the first transmission gear 41 and the second transmission gear 42.

[0045] The rotating structure 20 has an inner end wall 23 and an outer end wall 24 , and the upper and lower ends of the inner end wall 23 and the outer end wall 24 are connected. The rotating structure 20 also has left and right side end walls perpendicular to the hinge shaft 25 , and the left and right side end walls are connected to the inner end wall 23 and the outer end wall 24 .

[0046] The detergent input cavity 21 is the upper part of the rotating structure 20, and a detergent input port 211 connected to the detergent input cavity 21 is provided at the upper part of the outer end wall 24. The detergent input port 211 is used to add detergent into the detergent input cavity 21. When the rotating structure 20 is in an upwardly opened state, the detergent input cavity 21 rotates inwardly and extends into the clothing input port 11, and the upper part of the outer end wall 24 rotates upwardly and inwardly, so that the detergent input port 211 is exposed and rotated into the clothing input port 11. At this time, the detergent input port 211 is located at the upper part of the detergent input cavity 21, which is conducive to the addition of detergent.

[0047] The water injection chamber 22 is located at the lower part of the rotating structure 20, and a plurality of water injection ports 221 communicating with the water injection chamber 22 are provided at the lower part of the outer end wall 24. The water injection ports 221 are used to flow the water in the water injection chamber 22 into the outer barrel. When the rotating structure 20 is in the downwardly opened state, the water injection chamber 22 rotates inwardly and extends into the clothing input port 11, and the lower part of the outer end wall 24 rotates downwardly and inwardly, so that the water injection ports 221 are exposed and rotated into the clothing input port 11. At this time, the water injection ports 221 are located at the upper part of the water injection chamber 22, which is conducive to injecting water into the outer barrel.

[0048] The washing machine further includes a detergent storage chamber 50, which is connected to the detergent input chamber 21. The detergent input into the detergent input chamber 21 flows into the detergent storage chamber 50 for storage. When the washing machine washes each time, the detergent is extracted from the detergent storage chamber 50. An extraction pump is provided to realize automatic addition of detergent, which is convenient for users to use. It is also conducive to the miniaturization of the rotating structure 20 and the reduction of the volume of the rotating structure 20. The detergent storage chamber 50 is preferably provided as an arc-shaped cavity or an annular cavity provided outside the clothing input port 11. The detergent storage chamber 50 surrounds the outside of the clothing input port 11, which is conducive to increasing the volume of the detergent storage chamber 50, and is conducive to the reasonable use of the space position in the control tray 10, and is conducive to the reasonable distribution of the weight of the detergent storage chamber 50. The detergent storage cavity 50 can be set as an annular cavity. Since an outwardly protruding receiving groove 12 is provided on the side wall of the clothing input port 11, in order to avoid the receiving groove 12, an opening or a fracture for avoiding the receiving groove 12 is opened on the detergent storage cavity 50; after the fracture is set, the detergent storage cavity 50 forms an unclosed ring, and the size of the fracture in the circumferential direction of the clothing input port 11 is larger than the size of the receiving groove 12 in the circumferential direction.

[0049] The detergent storage chamber 50 is connected to the detergent input chamber 21 through the second connecting pipe 72. The rotating structure 20 is provided with an outflow nozzle 26 for the detergent to flow out. The outflow nozzle 26 is in communication with the detergent input chamber 21. The second connecting pipe 72 is connected to the outflow nozzle 26, and the detergent input into the detergent input chamber 21 flows through the outflow nozzle 26 and the second connecting pipe 72 to reach the detergent storage chamber 50. In order to reduce the residual detergent input in the detergent input chamber 21, the outflow nozzle 26 is arranged in the middle of the rotating structure 20. When the rotating structure 20 is in an upwardly opened state, the height of the outflow nozzle 26 is lower than the bottom height of the detergent input chamber 21. It is preferred that the outflow nozzle 26 is arranged in the middle of the rotating structure 20. A through opening is opened on the receiving groove 12, and the outflow nozzle 26 extends from the through opening 121 and is connected to the second connecting pipe 72. When the rotating structure 20 rotates, the outflow nozzle 26 moves in the through opening 121.

[0050] See also Figure 6 and Figure 7 As shown, in order to achieve the dilution and dissolution of the detergent and prevent the detergent from directly dripping and contacting the clothes, a water inlet chamber 60 is provided in the control panel seat 10, and the water inlet chamber 60 is connected to the water inlet valve 80 to guide the external tap water into the water inlet chamber 60. At the beginning of the washing program of the washing machine, an appropriate amount of detergent is added from the detergent storage chamber 50 into the water inlet chamber 60, and then the water inlet valve 80 is opened to feed water into the water inlet chamber 60 for diluting and dissolving the detergent, and the water in the water inlet chamber 60 flows into the water injection chamber 22 and is injected into the outer barrel. A third connecting pipe 73 is provided between the water inlet chamber 60 and the detergent storage chamber 50, which is used to add the detergent stored in the detergent storage chamber 50 into the water inlet chamber 60.

[0051] A water injection nozzle 27 connected to the water injection chamber 22 is provided on the rotating structure 20, and a first connecting pipe 71 is provided between the water inlet chamber 60 and the water injection chamber 22. One end of the first connecting pipe 71 is connected to the water inlet chamber 60, and the other end is connected to the water injection nozzle 27; it is used to flow the water in the water inlet chamber 60 into the water injection chamber 22. The water injection nozzle 27 is located in the middle of the rotating structure 20, and it is preferably arranged that the water injection nozzle 27 and the outflow nozzle 26 are arranged side by side at the same height; the water injection nozzle 27 also extends from the through opening 121.

[0052] The water injection nozzle 27 and the outflow nozzle 26 can be arranged on the rear end wall of the rotating structure 20; or on the side end wall of the rotating structure 20, see Fig. 9 As shown, the position of the corresponding through-port 121 also needs to be changed.
