Description

Technical Field

[0001] The invention relates to automatic cleaning equipment, in particular to a cleaning machine. Background Art

[0002] A cleaning machine usually uses a water pump to drive water flow to spray and flush the object to be cleaned up and down, left and right to achieve a cleaning effect. Currently, commonly used cleaning machines include dishwashers. Dishwashers can complete a series of functions such as washing, rinsing, disinfection, and drying, greatly reducing the tedious manual labor intensity. Dishwashers have many advantages such as strong decontamination performance, thorough disinfection, and energy and water saving, and are becoming more and more popular among people.

[0003] A dishwasher is usually provided with a return water chamber at the bottom of the spray assembly of the dishwasher, and the return water chamber is covered with a filter assembly, which is used to filter the water flow of the spray assembly to clean the object to be cleaned. During cleaning, the residual food dirt is generally collected in the filter assembly through the filter assembly, and the water flow is filtered by the filter assembly and flows into the return water chamber, and then pumped out by the water pump to the spray assembly to clean the object to be cleaned, thereby realizing the function of circulating cleaning. After cleaning, the fine dirt is discharged with the sewage, and the large particles of dirt remain in the filter assembly, which needs to be manually cleaned, which is troublesome. If the cleaning is not timely, the remaining dirt is easy to breed bacteria, contaminate the tableware, and endanger human health. In order to solve this problem, a dishwasher with a dirt crushing assembly is launched on the market. The large particles of dirt remaining in the filter assembly are crushed by the dirt crushing assembly to form fine dirt, and then discharged from the dishwasher. The existing dirt crushing assembly is roughly divided into two types. One is to set a crushing knife in the cup, and the crushing knife is driven by a motor to crush the collected dirt and then discharge it; the other is to set a circulating crushing pump, and the circulating crushing pump is driven by a motor to perform circulating cleaning and crushing at the same time.

[0004] However, a dishwasher with a crushing blade in the cup holder needs to add an additional motor to drive the crushing blade in addition to the motor that drives the circulating water pump, which is costly and has a complicated internal structure. Although a dishwasher with a circulating crushing pump only needs one motor to drive, it will not crush and discharge large particles of dirt at once during crushing. Instead, the dirt will circulate in the washing machine with the water flow. When the dirt is washed with the water flow, the tableware is easily damaged. At the same time, it is easy to generate gas vortexes during crushing, which affects the performance of the water pump and seriously affects the cleaning performance. Summary of the invention

[0005] In order to at least partially solve the problems existing in the prior art, a cleaning machine is provided. The cleaning machine includes a body base, a spray cleaning component and a filter crushing component, the body base has a concave water return chamber, the spray cleaning component has a water pump, the water inlet of the water pump is connected to the water return chamber, the filter crushing component is located in the water return chamber, the filter crushing component has a crushing knife, the cleaning machine also includes a motor and a first one-way transmission member, the output shaft of the motor has a first rotation direction and a second rotation direction opposite to each other, the water pump is connected to the output shaft, and the crushing knife is connected to the output shaft through the first one-way transmission member, when the output shaft rotates in the first rotation direction, the first one-way transmission member is locked, and the motor only drives the water pump to rotate, and when the output shaft of the motor rotates in the second rotation direction, the first one-way transmission member transmits the rotation of the output shaft to the crushing knife to drive the crushing knife to rotate.

[0006] Through this arrangement, the functions of cyclic cleaning and dirt crushing can be achieved simultaneously by setting up one motor, and the cost of the cleaning machine is reduced without affecting the cleaning performance.

[0007] Exemplarily, the first one-way transmission member is coaxially connected to the rotating shaft of the water pump, and the cleaning machine further comprises a first transmission connection assembly, which is connected between the first one-way transmission member and the rotating shaft of the crushing knife to transmit the rotation of the first one-way transmission member to the rotating shaft of the crushing knife. Through this arrangement, the positions of the water pump and the crushing knife are more flexible, which is convenient for the internal layout of the cleaning machine.

[0008] Exemplarily, the first transmission connection assembly includes a first gear and a second gear meshing with each other, the first gear is coaxially connected to the first one-way transmission member, and the second gear is coaxially connected to the rotating shaft of the crushing knife. Therefore, through this arrangement, the performance of the cleaning machine is stable.

[0009] Exemplarily, the transmission ratio of the first gear to the second gear is less than 1. In this way, the rotation speed of the crushing knife can be increased, and the crushing efficiency can be improved.

[0010] Exemplarily, the first one-way transmission member is coaxially connected to the rotating shaft of the crushing knife, and the cleaning machine further comprises a second transmission connection assembly, which is connected between the output shaft of the motor and the first one-way transmission member to transmit the rotation of the output shaft to the first one-way transmission member. Through this arrangement, the first one-way transmission member can have more position options, which is convenient for the internal layout of the cleaning machine.

[0011] Exemplarily, the cleaning machine also includes a second one-way transmission member, through which the output shaft of the motor is connected to the rotating shaft of the water pump, and the second one-way transmission member transmits the rotation of the output shaft when the output shaft rotates along the first rotation direction, and is locked when the output shaft rotates along the second rotation direction.

[0012] Exemplarily, the second one-way transmission member comprises a one-way bearing. Through this arrangement, the water pump does not need a special water suction end arrangement, and the selection range of the water pump is wider.

[0013] Exemplarily, the output shaft of the motor includes a first output shaft and a second output shaft, the first output shaft extends upward out of the motor housing and is connected to the rotating shaft of the water pump, and the second output shaft extends downward out of the motor housing and is connected to the first one-way transmission member. Through this arrangement, the internal structure of the cleaning machine is simplified and the layout is more reasonable.

[0014] For example, the output shaft of the motor extends upward out of the motor housing and is connected to the rotating shaft of the water pump, the lower end of the output shaft is connected to the first one-way transmission member, the first one-way transmission member is located in the housing, and the motor further includes a third output shaft, one end of the third output shaft is connected to the first one-way transmission member and the other end extends downward out of the housing. With this arrangement, the internal structure of the cleaning machine can be further simplified.

[0015] Exemplarily, the first one-way transmission member includes a one-way bearing. Through this arrangement, the first one-way transmission member can be simple and compact in structure and easy to install.

[0016] Exemplarily, the motor is located below the water return chamber and is coaxially arranged with the water pump. With this arrangement, the motor is isolated from water, preventing dangerous accidents such as motor burning caused by water, thereby improving the safety of the cleaning machine. In addition, since the water pump is usually arranged above the bottom surface of the water return chamber, and the filtering and crushing assembly extends below the bottom surface of the water return chamber, there is a certain space below the water return chamber corresponding to the water pump, which is just enough to arrange the motor, thereby making the structure of the cleaning machine more compact.

[0017] Exemplarily, the bottom surface of the water return chamber has a concave crushing chamber, the crushing chamber has a drain port, the filtering and crushing assembly also includes a lifting cup, the lifting cup is provided with a filtering hole, the lifting cup is detachably arranged in the crushing chamber, and the crushing knife is rotatably arranged in the lifting cup. In this way, the crushing knife can be taken out together with the lifting cup, which is convenient for daily care, maintenance and replacement of the crushing knife.

[0018] Exemplarily, the cleaning machine further includes a filter screen, the filter screen covers the top surface of the water return chamber, the filter screen has a first opening and a second opening, the water pump passes through the first opening, the top of the lifting cup extends to above the second opening, and a water inlet is provided on the side of the top of the lifting cup. Through this arrangement, the water in the water return chamber has a better cleanliness, ensuring that the cleaning performance of the cleaning machine is higher.

[0019] Exemplarily, the spray cleaning assembly includes a spray arm, and the spray arm is connected to the water outlet at the top of the water pump. Through this arrangement, the output shaft of the motor rotates in the first rotation direction, driving the water pump to transfer water from the return water chamber into the spray arm through the water outlet of the water pump, thereby driving the spray arm to rotate and spray, making the cleaning water flow more three-dimensional and achieving cleaning without dead angles.

DETAILED DESCRIPTION

[0031] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0032] The present invention provides a cleaning machine 100. The cleaning machine 100 can be used in homes, restaurants, hotels and other environments to clean tableware such as bowls, chopsticks, plates, dishes, knives, forks, vegetables, fruits, etc. Therefore, the cleaning machine 100 provided herein can be a dishwasher, a fruit and vegetable cleaning machine and many other cleaning devices. In other words, in the case where it is necessary to use water flow to clean the objects to be cleaned (the bowls, dishes, vegetables, fruits, etc. mentioned above), the principle provided by the present invention can be adopted.

[0033] The following will be combined with the attached Figure 1-7 The cleaning machine 100 according to the embodiment of the present invention is described in detail.

[0034] like Figure 1-2 As shown, the cleaning machine 100 may include a body base 200, a spray cleaning component 300 and a filtering and crushing component 400. Exemplarily, the body base 200 may be located at the bottom of the cleaning machine 100. The body base 200 may be used to carry the cleaning water flow and the object to be cleaned. Preferably, the material of the body base 200 may be metal or plastic. The body base 200 may have a concave backwater chamber 210. The backwater chamber 210 can collect water that falls after cleaning the object to be cleaned. The backwater chamber 210 may be covered with a filter net 230, and the filter net 230 can prevent dirt in the water from entering the backwater chamber 210. The water flow in the backwater chamber 210 can be discharged by a water pump 310 for circulating cleaning of the object to be cleaned.

[0035] The spray cleaning assembly 300 may have a water pump 310. The water inlet of the water pump 310 may be connected to the water return chamber 210. The spray cleaning assembly 300 pumps water from the water return chamber 210 through the water pump 310, and then transports it upward to the spray arm 320. The spray arm 320 sprays the pumped water onto the object to be cleaned in the cleaning machine 100 to clean the object to be cleaned. The spray arm 320 may be located at the lower part of the cleaning machine 100 as shown in the figure, spraying the object to be cleaned from bottom to top; it may also be set at the upper part of the cleaning machine 100, spraying the object to be cleaned from top to bottom.

[0036] The filtering and crushing assembly 400 may be located in the water return chamber 210. Figure 1-2 , the filter crushing assembly 400 may include a lifting cup 420. The lifting cup 420 is arranged in the middle of the filter screen 230 and is recessed into the water return chamber 210. The filter screen 230 gradually tilts downward from all sides toward the lifting cup 420, so that the dirt filtered by the filter screen 230 can flow into the lifting cup 420 with the water flow. The filter crushing assembly 400 may have a crushing knife 410. The crushing knife 410 is arranged in the lifting cup 420. The crushing knife 410 may be composed of an upper blade and a lower handle, and when the blade rotates, large particles of dirt can be crushed into fine particles, making it easy to discharge.

[0037] The cleaning machine 100 further includes a motor 500 and a first one-way transmission member 610. The first one-way transmission member 610 may include a clutch, a ratchet, a one-way gear, and the like.

[0038] The output shaft 510 of the motor 500 may have a first rotation direction (e.g., right rotation) and a second rotation direction (e.g., left rotation) that are opposite to each other. The water pump 310 may be connected to the output shaft 510, and the crushing knife 410 may also be connected to the output shaft 510 through a first one-way transmission member 610. The first one-way transmission member 610 may be located at any position on the rotating shafts of the output shaft 510 and the crushing knife 410, or at any position between the output shaft 510 and the rotating shafts of the crushing knife 410. The first one-way transmission member 610 may be coaxial with the output shaft 510, coaxial with the crushing knife 410, or coaxial with both.

[0039] When the output shaft 510 rotates along the first rotation direction, the first one-way transmission member 610 can be locked, and the motor 500 can only drive the water pump 310 to rotate. When the output shaft 510 of the motor 500 rotates along the second rotation direction, the first one-way transmission member 610 can transmit the rotation of the output shaft 510 to the crushing knife 410 to drive the crushing knife 410 to rotate. In other words, when the output shaft 510 rotates along the first rotation direction, the first one-way transmission member 610 cannot transmit the rotation of the output shaft 510 to the rotating shaft of the crushing knife 410. In this way, only the water pump 310 can be driven to absorb and drain water, while the crushing knife 410 does not move. When the output shaft 510 rotates along the second rotation direction, only the crushing knife 410 can be driven to rotate, and the water pump 310 can rotate along the second rotation direction, but since this rotation direction is not the working direction of the water pump 310, it cannot absorb and drain water. The water pump 310 may include a one-way pump, that is, the water pump 310 can absorb and drain water when rotating in a first rotation direction, but cannot absorb and drain water when rotating in the opposite direction, such as idling. Taking the more commonly used impeller pump as an example, the water inlet of the water pump 310 may have a one-way axial flow water suction section to meet the above-mentioned use requirements. Optionally, when the crushing knife 410 rotates, the water pump 310 may not rotate, and this embodiment will be described in detail later.

[0040] like Figure 1 As shown, when the cleaning machine 100 cleans the object to be cleaned, the output shaft 510 of the motor 500 rotates along the first rotation direction, driving the water pump 310 to discharge the water in the water return chamber 210, thereby cleaning the object to be cleaned. During the cleaning process, the water flow and the dirt can flow to the filter 230. The water flow filtered by the filter 230 can enter the water return chamber 210. The water flow in the water return chamber 210 is discharged by the water pump 310 for cyclic cleaning of the object to be cleaned. The dirt that fails to pass through the filter 230 can be crushed by the crushing knife 410 of the filter crushing assembly 400. When the crushing knife 410 crushes the dirt, the output shaft 510 of the motor 500 rotates along the second rotation direction, driving the crushing knife 410 to crush the large particles of dirt, so that it forms fine dirt, which is then discharged to the outside of the cleaning machine 100. Through this arrangement, the functions of cyclic cleaning and dirt crushing can be achieved by setting a motor 500 at the same time, and the cost of the cleaning machine 100 is reduced without affecting the cleaning performance.

[0041] As mentioned above, if Figure 1-3 As shown, the spray cleaning assembly 300 may include a spray arm 320. Preferably, the spray arm 320 may be connected to the water outlet at the top of the water pump 310. Through this arrangement, the output shaft 510 of the motor 500 rotates along the first rotation direction, driving the water pump 310 to pass the water outlet of the water pump 310 into the spray arm 320, and then driving the spray arm 320 to rotate and spray, so that the cleaning water flow is more three-dimensional, and cleaning without dead angles is achieved.

[0042] For example, Figure 1-2 and Figure 4 As shown, the bottom surface of the return water chamber 210 may have a concave crushing chamber 220. The crushing chamber 220 may have a drain port 221. The drain port 221 may be connected to a sewage discharge port, and after cleaning, all the water in the cleaning machine 100 may be discharged. The lifting cup 420 may preferably be in the shape of an annular cup. A filter hole 430 may be provided on the lifting cup 420. The lifting cup 420 may be detachably disposed in the crushing chamber 220, for example, by a snap-fit ​​member. The crushing knife 410 may be rotatably disposed in the lifting cup 420, for example, by a bearing. Dirt that fails to pass through the filter screen 230 and water that fails to pass through the filter screen 230 in time may enter the lifting cup 420, and the water enters the return water chamber 210 through the filter hole 430. The output shaft 510 of the motor 500 rotates in the second rotation direction, driving the crushing blade 410 to crush large particles of dirt into fine dirt, which is then discharged to the outside of the cleaning machine 100 through the drain port 221. In this way, the crushing blade 410 can be taken out together with the lifting cup 420, which is convenient for daily care, maintenance and replacement of the crushing blade 410.

[0043] As mentioned above, if Figure 1-2 As shown, the filter screen 230 can cover the top surface of the water return chamber 210. The filter screen 230 can have a first opening 231 and a second opening 232. The water pump 310 can pass through the first opening 231. The top of the cup 420 can extend above the second opening 232. A water inlet 440 can be provided on the side of the top of the cup 420. Dirt that fails to pass through the filter screen 230 and water that fails to pass through the filter screen 230 in time can enter the cup 420 through the water inlet 440, and the water can be filtered through the cup 420 and flow into the water return chamber 210, while the dirt remains in the cup 420. After the dirt is crushed by the crushing knife 410, it is discharged to the outside of the cleaning machine 100 through the drain port 221. Through this arrangement, the water in the water return chamber 210 has a good cleanliness, ensuring that the cleaning performance of the cleaning machine 100 is high.

[0044] Preferably, if Figure 1 As shown, the first one-way transmission member 610 may include a one-way bearing. A one-way bearing is a bearing that can rotate freely in one direction and is locked in another direction. The one-way bearing can be of any type and model, and technicians in this field can also choose any type of one-way bearing that is currently available or may appear in the future, as long as it can achieve the above functions, so it will not be described in further detail. Through this arrangement, the first one-way transmission member 610 can be simple and compact in structure and easy to install.

[0045] For example, Figure 1-2As shown, the first one-way transmission member 610 can be coaxially connected to the rotating shaft of the water pump 310. The cleaning machine 100 can also include a first transmission connection assembly 710. The first transmission connection assembly 710 can be one or a combination of multiple transmission modes such as gear transmission, belt transmission, chain transmission, etc. The first transmission connection assembly 710 can have one or more functions, such as one or more functions of speed increase, speed reduction, change of transmission direction, etc. The first transmission connection assembly 710 can be connected between the first one-way transmission member 610 and the rotating shaft of the crushing knife 410, so that the rotation of the first one-way transmission member 610 can be transmitted to the rotating shaft of the crushing knife 410. Through this arrangement, the positions of the water pump 310 and the crushing knife 410 are more free, which is convenient for the internal layout of the cleaning machine 100.

[0046] Preferably, if Figure 1-2 As shown, the first transmission connection assembly 710 may include a first gear 711 and a second gear 712 meshing with each other. The first gear 711 is coaxially connected to the first one-way transmission member 610. The second gear 712 is coaxially connected to the rotating shaft of the crushing knife 410. Gear transmission has many advantages such as reliable operation, long service life, high transmission ratio efficiency, compact mechanism, and wide power and speed application range. Therefore, through this arrangement, the cleaning machine 100 has stable performance.

[0047] Preferably, the transmission ratio of the first gear 711 to the second gear 712 is less than 1. In this way, the rotation speed of the crushing knife 410 can be increased, thereby improving the crushing efficiency.

[0048] In the second embodiment, if Figure 5 As shown, the first one-way transmission member 610' can be coaxially connected to the rotating shaft of the crushing knife 410. The cleaning machine 100 can also include a second transmission connection assembly. The second transmission connection assembly can be connected between the output shaft 510 of the motor 500 and the first one-way transmission member 610' to transmit the rotation of the output shaft 510 to the first one-way transmission member 610'. The second transmission connection assembly can refer to the description of the corresponding part of the first transmission connection assembly 710, which will not be repeated herein for the sake of brevity. Through this arrangement, the first one-way transmission member 610' can have more position options, which is convenient for the internal layout of the cleaning machine 100.

[0049] In the third embodiment, if Figure 6As shown, the cleaning machine 100 may further include a second one-way transmission member 620. The output shaft 510 of the motor 500 may be connected to the rotating shaft of the water pump 310 through the second one-way transmission member 620. The second one-way transmission member 620 may drive the output shaft 510 to rotate when the output shaft 510 rotates in a first rotation direction, and may be locked when the output shaft 510 rotates in the second rotation direction. Like the first one-way transmission member 610, the second one-way transmission member 620 may also include a clutch, a ratchet, a one-way gear, etc. Through this arrangement, the water pump 310 does not need a special water suction end arrangement, and the water pump 310 has a wider range of choices.

[0050] Preferably, if Figure 6 As shown, the second one-way transmission member 620 may include a one-way bearing. The one-way bearing may refer to the description of the corresponding part of the first one-way transmission member 610, which will not be repeated herein for the sake of brevity. Through this arrangement, the second one-way transmission member 620 can be made simple and compact in structure and easy to install.

[0051] Although Figure 6 The second one-way transmission member 620 is shown to be used in combination with the first one-way transmission member 610 in the first embodiment, but the second one-way transmission member 620 can also be combined with the second embodiment described above and the fourth embodiment to be described later.

[0052] Preferably, if Figure 1 As shown, the motor 500 can be located below the backwater chamber 210 and coaxially arranged with the water pump 310. The motor 500 can be connected and fixed below the backwater chamber 210 by a threaded connector or a snap-fit ​​connector. The output shaft 510 of the motor 500 can extend into the cleaning machine 100 through the motor mounting hole below the backwater chamber 210 and be connected to the rotating shaft of the water pump 310. Through this arrangement, the motor 500 is isolated from water, preventing dangerous accidents such as the burning of the motor 500 caused by water, thereby improving the safety of the cleaning machine 100. In addition, since the water pump 310 is usually arranged above the bottom surface of the backwater chamber 210, and the filtering and crushing assembly 300 will extend below the bottom surface of the backwater chamber 210, there is a certain space below the backwater chamber 210 corresponding to the water pump 310, which can just be used to arrange the motor 500, thereby making the structure of the cleaning machine 100 more compact.

[0053] Of course, in other embodiments not shown, if the layout allows, the output shaft 510 of the motor 500 can also be coaxially connected to the crushing knife 410. Optionally, the motor 500 can also be non-coaxial with the water pump 310 and the crushing knife 410, but transmits rotation to the water pump 310 and the crushing knife 410 through other transmission devices connected therebetween. In addition, if the layout allows, the motor 500 can be located above, on the side, or at any other suitable position of the water return chamber 210.

[0054] Preferably, if Figure 1-3 As shown, the output shaft 510 of the motor 500 may include a first output shaft 511 and a second output shaft 512. The first output shaft 510 may extend upward out of the housing 520 of the motor 500 and be connected to the rotating shaft of the water pump 310. The second output shaft 512 may extend downward out of the housing 520 of the motor 500 and be connected to the first one-way transmission member 610. The first output shaft 511 and the second output shaft 512 may be two ends of the same output shaft 510. Through this arrangement, the internal structure of the cleaning machine 100 is simplified and the layout is more reasonable.

[0055] In the fourth embodiment, if Figure 7 As shown, the output shaft 510 of the motor 500 can extend upward out of the housing 520 of the motor 500 and be connected to the rotating shaft of the water pump 310. The lower end of the output shaft 510 can be connected to the first one-way transmission member 610''. The first one-way transmission member 610'' can be located in the housing 520. The motor 500 can also include a third output shaft 530. One end of the third output shaft 530 can be connected to the first one-way transmission member 610'' and the other end extends downward out of the housing 520 and can be connected to the rotating shaft of the crushing knife 410. Through this arrangement, the internal structure of the cleaning machine 100 can be further simplified.

[0056] In the description of the present invention, it is necessary to understand that the orientation or positional relationship indicated by directional words such as "front", "back", "up", "down", "left", "right", "lateral", "vertical", "vertical", "horizontal", "top", "bottom", etc. is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.
