Two infusion pipes, one of which is connected between a drying agent storage box and a dishwashing chamber, and the other is connected between a detergent storage box and the dishwashing chamber, are connected. Rotation of the two rotating members creates negative pressure within the two infusion pipes, thereby transferring the drying agent in the drying agent storage box to the dishwashing chamber and the detergent in the detergent storage box to the dishwashing chamber. This allows the dishwasher to transfer both the detergent and the drying agent into the dishwashing chamber by controlling only one drive pump (more specifically, only one motor), significantly reducing the material cost of the dishwasher. Furthermore, since the detergent and the drying agent are driven separately by a single drive pump, the dishwasher's integration is improved, thereby reducing its assembly and transportation costs. It can be seen that compared with the current dishwashers, the dishwasher of the technical solution of this application has the advantages of low material cost, low component cost and low transportation cost.

[0043] The utility model provides a dishwasher.

[0044] In the embodiment of the present utility model, Figures 1 to 7 As shown, the dishwasher includes a cabinet 10 , a drying agent storage box 60 , a detergent storage box 70 and a driving pump 20 .

[0045] Specifically, the cabinet 10 is provided with a dishwashing cavity 11 , and a cavity wall of the dishwashing cavity 11 is provided with a drain port for discharging food residues and cleaning liquid.

[0046] The drying agent storage box 60 and the detergent storage box 70 are both provided in the cabinet 10 . The drying agent storage box 60 is used to store the drying agent, and the detergent storage box 70 is used to store the detergent.

[0047] The driving pump 20 includes a motor 21, two pump housings 22, two rotating parts 23, two infusion pipelines, and two one-way transmission structures.

[0048] Two output shafts are respectively provided at both ends of the motor 21 , and the two output shafts rotate in the same direction, that is, the two output shafts either rotate in a clockwise direction or in a counterclockwise direction at the same time.

[0049] The two pump housings 22 are respectively arranged at both ends of the motor 21, and a pump cavity 225 is formed inside the two pump housings 22; the two rotating parts 23 are respectively rotatably installed in the two pump cavities 225, and the two rotating parts 23 are respectively connected to the two output shafts of the motor 21 through two unidirectional transmission structures.

[0050] Among them, one of the two one-way transmission structures is configured to transmit power only when the output shaft of the motor 21 rotates around the first direction, and the other is configured to transmit power only when the output shaft of the motor 21 rotates around the second direction.

[0051] One of the two infusion pipes is connected between the drying agent storage box 60 and the dishwashing chamber 11, and the other is connected between the detergent storage box 70 and the dishwashing chamber 11. When the two rotating parts 23 rotate, negative pressure is formed in the two infusion pipes respectively, so that the drying agent in the drying agent storage box 60 is transferred to the dishwashing chamber 11, and the detergent in the detergent storage box 70 is transferred to the dishwashing chamber 11.

[0052] To facilitate understanding of this solution, it is assumed that the two output shafts of the motor 21 are respectively the first output shaft and the second output shaft, the two rotating members 23 are respectively the first rotating member 23 and the second rotating member 23; the two infusion pipelines are respectively the first infusion pipeline and the second infusion pipeline; and the two one-way transmission structures are respectively the first one-way transmission structure and the second one-way transmission structure.

[0053] Two pump housings 22 are disposed at either end of the motor 21, and each pump housing 22 defines a pump chamber 225. A first rotating member 23 and a second rotating member 23 are rotatably mounted within the two pump chambers 225, respectively. The first output shaft of the motor 21 is in transmission connection with the first rotating member 23 via a first one-way transmission structure. The first one-way transmission structure is configured to transmit power between the first output shaft of the motor 21 and the first rotating member 23 only when the first output shaft of the motor 21 rotates in a first direction, thereby causing the first rotating member 23 to rotate within the pump chamber 225. When the first output shaft of the motor 21 rotates in a second direction, the first one-way transmission structure does not transmit power to the first rotating member 23.

[0054] The second output shaft of the motor 21 is connected to the second rotating member 23 through a second one-way transmission structure; the second one-way transmission structure is configured to transmit power between the output shaft of the motor 21 and the second rotating member 23 only when the second output shaft of the motor 21 rotates around the second direction, so that the second rotating member 23 rotates in the pump chamber 225, and when the first output shaft of the motor 21 rotates around the first direction, the second one-way transmission structure will not transmit power to the second rotating member 23.

[0055] In this way, regardless of whether the first output shaft and the second output shaft of the motor 21 rotate simultaneously in the first direction or the second direction, at least one of the first one-way transmission structure and the second one-way transmission structure can transmit power, that is, at least one of the first rotating member 23 and the second rotating member 23 rotates within the pump chamber 225. One of the first direction and the second direction is clockwise, and the other is counterclockwise. That is, when the first direction is clockwise, the second direction is counterclockwise; and when the first direction is counterclockwise, the second direction is clockwise.

[0056] The first liquid infusion pipeline is connected between the drying agent storage box 60 and the dishwashing chamber 11; when the first output shaft of the motor 21 rotates around the first direction, negative pressure is formed in the first liquid infusion pipeline, and under the action of the negative pressure, the drying agent in the drying agent storage box 60 is transferred to the dishwashing chamber 11.

[0057] The second infusion pipe is connected between the detergent storage box 70 and the dishwashing chamber 11. When the second output shaft of the motor 21 rotates in the second direction, negative pressure is formed in the first infusion pipe. Under the action of the negative pressure, the detergent in the detergent storage box 70 is transferred to the dishwashing chamber 11.

[0058] In other words, when the drying agent needs to be transferred to the dishwashing chamber 11, the motor 21 only needs to be controlled to rotate in the first direction. When the detergent needs to be transferred to the dishwashing chamber 11, the motor 21 only needs to be controlled to rotate in the second direction. In other words, by controlling the rotation direction of the motor 21, the drying agent and detergent can be transferred. This eliminates the need for a separate drive pump 20 for each of the drying agent storage box 60 and the detergent storage box 70.

[0059] Optionally, the first direction and the second direction may be set to be clockwise and counterclockwise, respectively.

[0060] Specifically, in some embodiments, the driving pump 20 also includes two infusion tubes 24, both of which are hollow to form infusion pipes, and the two infusion tubes 24 are respectively arranged in the two pump chambers 225. One end of the two infusion tubes 24 is connected to the drying agent storage box 60, and the other end is connected to the dishwashing chamber 11. The other end of the two infusion tubes 24 is connected to the detergent storage box 70, and the other end is connected to the dishwashing chamber 11.

[0061] In another embodiment, the driving pump 20 further includes an inlet pipe and an outlet pipe. One end of the inlet pipe is connected to the detergent storage box 70 or the rinse agent storage box 60 and the other end is connected to the pump chamber 225. One end of the outlet pipe is connected to the dishwashing chamber 11 and the other end is connected to the pump chamber 225. The inlet pipe, the pump chamber 225, and the outlet pipe form a liquid delivery pipe. The specific configuration can be determined according to actual conditions and is not specifically limited in this application.

[0062] In summary, the dishwasher of the present invention comprises two rotating members 23 rotatably mounted within two pump chambers 225, each of which is connected to the two output shafts of the motor 21 via two one-way transmission structures. One of the two one-way transmission structures is configured to transmit power only when the output shaft of the motor 21 rotates in a first direction, and the other is configured to transmit power only when the output shaft of the motor 21 rotates in a second direction. Furthermore, two liquid infusion pipes are connected, one between the drying agent storage box 60 and the dishwashing chamber 11, and the other between the detergent storage box 70 and the dishwashing chamber 11. Rotation of the two rotating members 23 creates negative pressure within the two liquid infusion pipes, thereby transferring the drying agent in the drying agent storage box 60 and the detergent in the detergent storage box 70 to the dishwashing chamber 11. This allows the dishwasher to transfer both detergent and drying agent into the dishwashing chamber 11 by controlling only one drive pump 20 (more specifically, only one motor 21), significantly reducing the material cost of the dishwasher. Furthermore, since the detergent and the rinse aid are driven separately by a single drive pump 20, the dishwasher's integration is improved, thereby reducing its assembly and transportation costs. Thus, compared to existing dishwashers, the dishwasher of the present invention has the advantages of low material cost, low component cost, and low transportation cost.

[0063] In some embodiments, the one-way transmission structure includes a one-way bearing, through which the output shaft of the motor 21 is connected to the rotating member 23. It will be appreciated that a one-way bearing is capable of free rotation in only one direction and is locked in the other. In this embodiment, the one-way bearing connects the output shaft of the motor 21 and the rotating member 23, resulting in a simpler structure and easier installation, which helps reduce the difficulty of assembling the drive pump 20. Of course, in other embodiments, the one-way transmission structure can be configured as a ratchet.

[0064] In some embodiments, the rotating member 23 includes a rotating body 231, and the rotating body 231 is provided with a first assembly groove on the side facing the motor 21. The pump housing 22 is provided with a second assembly groove, and the second assembly groove is arranged toward the first assembly groove. The second assembly groove and the first assembly groove cooperate with each other to form a bearing seat, and the one-way bearing is installed on the bearing seat.

[0065] Specifically, the rotating body 231 has a first mounting seat on one side facing the motor 21. The first mounting seat is provided with a first assembly groove. The pump housing 22 is provided with a second mounting seat, which is arranged toward the first mounting seat and is provided with a second assembly groove. The first mounting seat and the second mounting seat cooperate with each other to form a bearing seat, in which the one-way bearing is mounted. As is known, the bearing seat can lubricate the bearing with lubricating oil inside it, reducing friction and wear and ensuring the long-term stable operation of the bearing. In this embodiment, installing the one-way bearing in the bearing seat makes the one-way bearing transmission more stable and can also increase the service life of the one-way bearing.

[0066] The formation of the bearing seat is optional. In some embodiments, the first mounting seat and the second mounting seat are assembled to form the bearing seat. In another embodiment, the first mounting seat is inserted into the second mounting groove to form the bearing seat. In yet another embodiment, the second mounting seat is inserted into the first mounting groove to form the bearing seat. The specific configuration can be determined based on actual conditions and is not specifically limited in this application.

[0067] In some embodiments, the rotating member 23 also includes at least two rolling structures arranged at intervals, and the two rolling structures are both installed on the rotating body 231, and an extrusion gap is formed between the rolling structure and the side wall of the pump chamber 225; the pump housing 22 is also provided with an inlet 223 and an outlet 224 connected to the pump chamber 225; the driving pump 20 also includes two infusion tubes 24, and the two infusion tubes 24 respectively form two infusion pipelines, and the two infusion tubes 24 respectively pass through the two pump housings 22, wherein the infusion tube 24 enters the pump chamber 225 from the inlet 223, and leaves the pump chamber 225 from the outlet 224 after passing through the extrusion gap.

[0068] Specifically, the two infusion tubes 24 are both hoses. The two infusion tubes 24 are respectively inserted into the extrusion gaps of the two pump housings 22. One end of the two infusion tubes 24 extends from the inlet 223 to communicate with the drying agent storage box 60, and the other end extends from the outlet 224 to communicate with the dishwashing chamber 11. The other one of the two infusion tubes 24 extends from the inlet 223 to communicate with the detergent storage box 70, and the other end extends from the outlet 224 to communicate with the dishwashing chamber 11.

[0069] When the rotating member 23 rotates, the two roller structures squeeze the liquid infusion tube 24. This creates a vacuum inside the liquid infusion tube 24, drawing in the drying agent or detergent. The two roller structures then squeeze the tube again to squeeze the drying agent or detergent out. This demonstrates that the drive pump 20 of this application is a peristaltic pump. As we know, peristaltic pumps can precisely control the amount of liquid delivered. When applied to the technical solution of this application, they can precisely control the amount of drying agent and detergent delivered.

[0070] In some embodiments, the rolling structure includes a pressure roller 233. The rotating body 231 includes a rotating column and two mounting plates 232. The rotating column is connected to the one-way transmission structure. The two mounting plates 232 are respectively mounted at both ends of the rotating column. The ends of the pressure roller 233 are rotatably mounted on the two mounting plates 232, and at least a portion of the pressure roller 233 protrudes from the side of the mounting plates 232. In other words, the two mounting plates 232 are used to provide mounting locations for the two rolling structures, thereby reducing the difficulty of installing the pressure roller 233.

[0071] Furthermore, both mounting plates 232 are provided with a plurality of mounting notches, which are spaced apart along the circumference of the mounting plates 232. Each mounting notch extends through the sidewall of the mounting plates 232, and the multiple mounting notches on the two mounting plates 232 correspond one to one. In other words, the pressure roller 233 is mounted between the two mounting plates 232 via the mounting notches. The provision of the mounting notches reduces the difficulty of removing the pressure roller 233.

[0072] In some embodiments, the pump housing 22 includes a cover 221 and a housing 222. The housing 222 is open, facing away from the motor 21, and the cover 221 is detachably mounted to the open side of the housing 222. This separates the pump housing 22 into the cover 221 and the housing 222, and the cover 221 and the housing 222 are detachably connected. If the rotating member 23 is damaged, the cover 221 and the housing 222 can be separated, facilitating subsequent repairs. Of course, in other embodiments, the cover 221 and the housing 222 are integrally formed.

[0073] Furthermore, the rotating member 23 also includes a rotating shaft 235. The rotating shaft 235 is protruding from the side of the rotating body 231 facing the cover 221. The cover 221 is provided with a slot, and the rotating shaft 235 is rotatably inserted into the slot. Specifically, the slot is provided on the side of the cover 221 facing the opening, and the rotating shaft 235 is rotatably inserted into the slot to ensure more stable rotation of the rotating member 23. Of course, in other embodiments, the slot can be omitted from the side of the cover 221 facing the opening.

[0074] In some embodiments, the rotating member 23 further includes a plurality of reinforcing ribs 234. The plurality of reinforcing ribs 234 are disposed on the rotating body and spaced apart along the circumference of the rotating body. The ends of the reinforcing ribs 234 are respectively connected to the two mounting plates 232. In other words, the structural strength of the rotating member 23 is enhanced by the plurality of reinforcing ribs 234.

[0075] In some embodiments, the dishwasher also includes a high-temperature water tank 30 and a spray assembly 50. The high-temperature water tank 30 is arranged in the cabinet 10. One end of one of the two infusion tubes 24 is connected to the high-temperature water tank 30 and the other end is connected to the drying agent storage box 60. One end of the other is connected to the high-temperature water tank 30 and the other end is connected to the detergent storage box 70. The spray assembly 50 is movably arranged in the dishwashing cavity 11 and is connected to the high-temperature water tank 30.

[0076] Specifically, the liquid delivery pipe 24 transfers the drying agent and detergent to the high-temperature water tank 30 to mix with the high-temperature water.

[0077] During the main wash phase, the liquid infusion pipe 24 transfers the detergent to the high-temperature water tank 30 to mix with water, and then the mixture of water and detergent is sprayed into the dishwashing chamber 11 through the spray assembly 50 to wash the dishes.

[0078] During the rinsing stage, the liquid infusion pipe 24 transfers the drying agent to the high-temperature water tank 30 to mix with water, and then the mixture of water and drying agent is sprayed into the dishwashing chamber 11 through the spray assembly 50 to perform the main wash of the dishes.

[0079] The spray assembly 50 is movable in the dishwashing cavity 11 , so the spraying area of ​​the spray assembly 50 can be increased, thereby being able to fully clean the tableware and improving the cleaning effect on the tableware.

[0080] The dishwasher further includes a circulating water tank 40, which is disposed within the cabinet 10 and communicates with the dishwashing chamber 11 to collect cleaning liquid (including but not limited to water, detergent, or a mixture thereof) after pre-washing. The spray assembly 50 is communicated with both the high-temperature water tank 30 and the circulating water tank 40. During the main wash phase, the cleaning liquid collected in the circulating water tank 40 can be used to clean the dishes, thereby reusing water and reducing water waste.

[0081] Furthermore, the high-temperature water tank 30 and the circulating water tank 40 are both located at the bottom of the cabinet 10. Specifically, this utilizes the space at the bottom of the cabinet 10 to house the high-temperature water tank 30 and the circulating water tank 40, which helps reduce the space occupied by the dishwasher. Of course, in other embodiments, the high-temperature water tank 30 and the circulating water tank 40 are both located at the top of the cabinet 10.

[0082] In some embodiments, the side of the cabinet 10 is provided with an entrance communicating with the dishwashing chamber 11. The dishwasher also includes a cabinet door 12 and a cutlery basket. The cabinet door 12 is movable relative to the cabinet 10 for opening and closing the entrance. The cutlery basket is located on the side of the cabinet door 12 facing the dishwashing chamber 11. Specifically, the dishwashing chamber 11 is connected to the outside environment through the entrance. When the cutlery basket is needed to place the dishes to be cleaned, the user can move the cabinet door 12 to the dining table to collect the dishes. After collecting the dishes, the cabinet door 12 is directly pushed into the dishwashing chamber 11 through the entrance to clean them. After cleaning the dishes, the cabinet door 12 is simply pulled out, allowing the cleaned dishes to be placed in the cutlery storage area. This is quick and efficient, helping to reduce labor costs. Of course, in other embodiments, the cabinet door 12 is rotatably located at the entrance to open and close the entrance, and the cutlery basket is located within the dishwashing chamber 11.

[0083] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
