Technical Field

[0001] This utility model belongs to the field of dishwasher technology, specifically relating to a dispenser and dishwasher for a multi-functional dishwasher. Background Technology

[0002] Dishwashers are increasingly widely used due to their advantages such as good cleaning effect, food disinfection, and time and labor saving. A patent with publication number CN110916587B discloses a dishwasher and a dispenser and door assembly for it. The dispenser includes: a dispenser housing with a liquid storage chamber, an external dispensing port, and a dispensing outlet; a storage compartment with a storage cover; and a pump assembly located in the dispenser housing, having a suction port and a pumping port. The suction port communicates with the liquid storage chamber, and the pumping port communicates with the dispensing outlet. The existing dispenser's internal pump structure has many limitations, resulting in inaccurate dispensing of rinsing agents; furthermore, it cannot dispense solid cleaning consumables such as dishwasher detergent powder, exhibiting poor versatility. Therefore, there is a need to design a dispenser and dishwasher for a multi-functional dishwasher to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a dispenser for a multi-functional dishwasher. This invention connects the dishwasher powder dispensing component to the water inlet, enabling direct dispensing of solid dishwasher powder. It also includes a dishwasher liquid dispensing chamber and a rinse aid dispensing chamber, resulting in better versatility.

[0004] The objective of this invention is achieved through the following technical solution: A dispenser for a multi-functional dishwasher includes a dispenser housing, which contains a dishwasher detergent dispenser chamber, a dishwasher liquid dispenser chamber, and a rinse aid dispenser chamber. An external liquid storage chamber is provided on the dispenser housing, which is connected to the dishwasher liquid dispenser chamber. A piston pump body and a piston pump dispensing area are provided within the dispenser housing, with the piston pump body positioned between the dispensing area and the external liquid storage chamber. The dispenser housing also includes a rinse aid storage chamber connected to the rinse aid dispenser chamber, and two adjacent rinse aid dispensing areas and a rinse aid volume-regulating chamber are located on the side of the rinse aid storage chamber. Furthermore, the dispenser housing contains a water inlet path, from which two parallel pre-wash and rinsing water paths branch out. An electromagnetic reversing valve body is provided within the dispenser housing for switching the flow direction of the water inlet path. The pre-wash water path is connected to the piston pump dispensing area, and the rinsing water path faces the dishwasher detergent dispenser chamber.

[0005] Preferably, the dispenser housing is provided with a combined dispensing device rotatably connected thereto, and a first rotating shaft is provided between the combined dispensing device and the dispenser housing for connecting the two; the combined dispensing device is provided with two dishwashing liquid dispensing chambers and a rinsing agent dispensing chamber arranged side by side and adjacent to each other; the opening end of the combined dispensing device is provided with a sealing cover detachably connected thereto, and a first sealing element is provided between the sealing cover and the combined dispensing device for sealing.

[0006] Preferably, the dishwashing liquid dispensing chamber has a first outlet, and a first flexible tube connects the first outlet to the external storage chamber; the dispenser housing has a first connection port, and a second flexible tube connects the first connection port to the external storage chamber; the dispenser housing contains a piston pump body for extraction, the piston pump body has a piston pump inlet and a piston pump outlet, the piston pump inlet communicates with the first connection port, and the piston pump outlet communicates with the piston pump dispensing area; a photoelectric liquid level sensor is provided at the bottom of the outer side of the external storage chamber; the dispenser housing also has a dishwashing liquid dispensing port, which is directly connected to the piston pump dispensing area.

[0007] Dishwashing liquid is used in large quantities in daily life, so an external reservoir is included for expanded storage capacity, allowing for extended use without frequent refills. This external reservoir also makes it compatible with various dishwasher sizes, improving its versatility. Due to the high viscosity of the dishwashing liquid, a photoelectric level sensor is used to detect the level. This sensor utilizes the principle of light reflection and refraction at the interface of two different media, avoiding direct contact with the viscous liquid and ensuring accurate level detection.

[0008] A dishwashing liquid dispensing port is provided here, allowing the operator to add dishwashing liquid directly to the piston pump dispensing area in a single transaction. During daily use, the operator adds dishwashing liquid to the dispensing chamber and then seals it with the sealing cap. The dishwashing liquid flows through the first outlet into the external storage chamber. The piston pump then draws the dishwashing liquid from the external storage chamber along the second hose to the first connection port, and finally dispenses it from the piston pump into the piston pump dispensing area. The piston pump dispensing area is connected to the dishwashing area, completing the automatic dishwashing liquid dispensing process.

[0009] Preferably, the rinsing agent dispensing chamber has a second outlet, the dispenser housing has a rinsing agent storage chamber, and a third hose is provided between the second outlet and the rinsing agent storage chamber; the dispenser housing also has a rinsing agent dispensing area and a rinsing agent volume-fixing chamber, which are arranged adjacent to each other; the dispenser housing has an electromagnetic volume-fixing valve for controlling the flow channel, and a valve sealing ring is fixedly installed on the valve stem of the electromagnetic volume-fixing valve; the two inner walls of the rinsing agent volume-fixing chamber have a first volume-fixing chamber seal and a second volume-fixing chamber seal arranged parallel to each other, the first volume-fixing chamber seal is located near the rinsing agent dispensing area, and the second volume-fixing chamber seal is located near the rinsing agent storage chamber.

[0010] Preferably, the front end face of the dispenser housing is provided with a rinsing outlet, which is connected to the rinsing agent dispensing area; the electromagnetic volume-regulating dispensing valve includes a first spring for resetting, and when the electromagnetic volume-regulating dispensing valve is working, the control valve sealing ring moves relative to the first and second seals of the volume-regulating cavity.

[0011] Preferably, the rinse aid storage cavity is provided with a float assembly, and a magnet is installed on the float assembly; a magnetic switch assembly is provided on the outside of the rinse aid storage cavity, adjacent to the float assembly.

[0012] The rinsing agent has a relatively low viscosity, so after being added, it automatically flows to the rinsing agent storage chamber through the second outlet. In the default state, the valve seal ring blocks the second seal of the volume-fixing chamber, allowing the rinsing agent to accumulate within the storage chamber. When the electromagnetic volume-fixing valve is energized, its stem causes the valve seal ring to contract, moving it from the second seal to the first seal. This allows the rinsing agent to flow from the storage chamber into the volume-fixing chamber. When the electromagnetic volume-fixing valve is de-energized, the valve seal ring automatically resets under the action of the first spring, re-blocking the second seal. At this point, the first seal is open, allowing the designated volume of rinsing agent to flow from the volume-fixing chamber to the rinsing agent dispensing area, and then from there to the rinsing agent dispensing outlet, which connects to the dish and chopstick work area. This completes the automatic dispensing process.

[0013] Since the rinse aid is in liquid form, a float assembly is installed in the rinse aid storage chamber for liquid level detection. When the liquid level is low, the magnet on the float assembly approaches the magnetic switch assembly, which then sends an electrical signal to the dishwasher's control panel, triggering an alarm program. The magnet is an existing part and is not shown in the accompanying drawings.

[0014] Preferably, the dispenser housing is provided with a dishwasher detergent dispensing assembly rotatably connected thereto, and a second rotating shaft is provided between the dishwasher detergent dispensing assembly and the dispenser housing for connecting the two; the dishwasher detergent dispensing assembly has a dishwasher detergent dispensing chamber inside, and the dishwasher detergent dispensing assembly is located directly below the combined dispensing device; the dispenser housing is provided with a water inlet for connecting to an external water source, and the water inlet is connected to the water inlet path; the bottom of the dishwasher detergent dispensing chamber is provided with a drain hole, and a liquid outlet is provided between the bottom of the dishwasher detergent dispensing assembly and the dispenser housing; the dispenser housing is provided with an electromagnetic reversing valve body for switching the flow direction of the water inlet path.

[0015] Preferably, the water inlet path is divided into a pre-wash water path and a rinsing water path on the distributor housing. The end of the rinsing water path is provided with an inclined outlet, which is set towards the dishwashing powder dispensing chamber. The pre-wash water path is connected to the piston pump dispensing area.

[0016] Preferably, the electromagnetic reversing valve body includes a valve sealing rod, and the distributor housing is provided with an electromagnetic reversing valve port, a pre-wash valve port, and a dishwasher detergent water circuit valve port. The pre-wash valve port is connected to the pre-wash water circuit; the dishwasher detergent water circuit valve port is connected to the rinsing water circuit; the electromagnetic reversing valve port is located between the pre-wash valve port and the dishwasher detergent water circuit valve port; the electromagnetic reversing valve body also includes a second spring for resetting.

[0017] Connected to an external water source via the inlet, the electromagnetic reversing valve body can switch between the rinsing and pre-rinsing water paths. When the electromagnetic reversing valve body is energized, the valve sealing rod moves to the valve port under the action of electromagnetic force, at which point the pre-rinsing valve port opens, and water flows from the inlet water path along the pre-rinsing valve port into the pre-rinsing water path. When de-energized, the valve sealing rod moves to the pre-rinsing valve port under the action of the second spring; at this time, the pre-rinsing water path closes, and water flows from the inlet water path along the detergent dispensing valve port into the rinsing water path. The pre-rinsing water path pre-rinses the dishes and utensils in the work area, while the rinsing water path uses water flow to dispense the detergent; this eliminates the need to empty the detergent, reducing structural costs. Since the inclined outlet faces the detergent dispensing chamber, the high-speed water flow rinses the detergent dispensing chamber. When water overflows from the detergent dispensing chamber, it is released into the dish and utensil work area through the liquid outlet. Residual water in the detergent dispensing chamber flows out through the drain hole, thus preventing water stains from remaining in the detergent dispensing chamber.

[0018] Because the pre-wash water circuit is connected to the piston pump's dispensing area, this ensures that the water flow can flush the dishwashing liquid dispensing port, preventing the high-viscosity dishwashing liquid residue from condensing and avoiding affecting the normal operation of the piston pump.

[0019] This utility model also proposes a dishwasher for use as a dispenser in a multi-functional dishwasher.

[0020] Compared with existing technologies, this utility model has the following advantages: 1. This utility model can freely dispose of various types of washing consumables, making it more versatile; 2. The dispensing method can be freely selected. Dishwashing liquid and rinsing agent can be automatically dispensed, while dishwashing powder can be manually dispensed in a single application; 3. To address the different viscosities of dishwashing liquid and rinsing agent, two independent dispensing channels are set up, greatly improving dispensing efficiency and accuracy; 4. The external liquid storage chamber offers flexible application scenarios and better versatility; 5. Dishwashing powder dispensing does not require flipping and can be directly rinsed and dissolved, resulting in lower manufacturing costs; 6. The integrated design of the dishwashing powder dispensing chamber, dishwashing liquid dispensing chamber, and rinsing agent dispensing chamber maximizes space utilization.

[0035] The dispenser housing 1 is provided with a dishwasher detergent dispensing assembly 33 rotatably connected thereto, and a second rotating shaft 34 is provided between the dishwasher detergent dispensing assembly 33 and the dispenser housing 1 for connecting the two; the dishwasher detergent dispensing assembly 33 is provided with a dishwasher detergent dispensing chamber 2, and the dishwasher detergent dispensing assembly 33 is located directly below the combined dispensing device 15; the dispenser housing 1 is provided with a water inlet 35 for connecting to an external water source, and the water inlet 35 is connected to the water inlet channel 11; the bottom of the dishwasher detergent dispensing chamber 2 is provided with a drain hole 36, and a liquid outlet 37 is provided between the bottom of the dishwasher detergent dispensing assembly 33 and the dispenser housing 1; the dispenser housing 1 is provided with an electromagnetic reversing valve body 14 for switching the flow direction of the water inlet channel 11. The water inlet channel 11 branches into a pre-wash channel 12 and a rinsing channel 13 on the distributor housing 1. The end of the rinsing channel 13 is provided with an inclined outlet 38, which faces the dishwashing powder dispensing chamber 2. The pre-wash channel 12 is interconnected with the piston pump dispensing area 7. The electromagnetic reversing valve body 14 includes a valve sealing rod 141. The distributor housing 1 is provided with an electromagnetic reversing valve port 39, a pre-wash valve port 40, and a dishwashing powder water channel valve port 41. The pre-wash valve port 40 is connected to the pre-wash channel 12. The dishwashing powder water channel valve port 41 is connected to the rinsing channel 13. The electromagnetic reversing valve port 39 is located between the pre-wash valve port 40 and the dishwashing powder water channel valve port 41. The electromagnetic reversing valve body 14 also includes a second spring 142 for resetting.

[0036] The specific working process of this embodiment is as follows: Since dishwashing liquid is used in large quantities in daily life, an external storage chamber 5 is provided to expand the storage capacity, allowing for long-term use without frequent refills. Simultaneously, the external storage chamber 5 is compatible with various dishwasher sizes, offering better versatility. Due to the high viscosity of the dishwashing liquid, a photoelectric liquid level sensor 23 is used to detect the liquid level. The photoelectric liquid level sensor 23 utilizes the principle of light reflection and refraction at the interface of two different media, avoiding direct contact with the high-viscosity dishwashing liquid and ensuring accurate liquid level detection.

[0037] A dishwashing liquid dispensing port 24 is provided here, allowing the operator to directly add dishwashing liquid to the piston pump dispensing area 7 in a single transaction. During daily use, the operator adds dishwashing liquid to the dishwashing liquid dispensing chamber 3 and then seals it with the sealing cap 17. The dishwashing liquid enters the external storage chamber 5 through the first outlet 19. The piston pump body 6 operates, drawing the dishwashing liquid from the external storage chamber 5 along the second hose 22 to the first connection port 21. Then, the dishwashing liquid is dispensed from the piston pump body 6 into the piston pump dispensing area 7. The piston pump dispensing area 7 is connected to the dishwashing and chopsticks working area, completing the automatic dishwashing liquid dispensing process.

[0038] The rinsing agent has a relatively low viscosity, so after the rinsing agent is added, it will automatically flow along the second outlet 25 to the rinsing agent storage chamber 8. In the default state, the valve sealing ring 271 blocks the second seal 29 of the volume-fixing cavity, allowing the rinsing agent to accumulate in the rinsing agent storage cavity 8. When the electromagnetic volume-fixing dispensing valve 27 is energized, the valve stem of the electromagnetic volume-fixing dispensing valve 27 causes the valve sealing ring 271 to contract. The valve sealing ring 271 then moves from the second seal 29 of the volume-fixing cavity to the first seal 28 of the volume-fixing cavity, allowing the rinsing agent to flow from the rinsing agent storage cavity 8 into the rinsing agent volume-fixing cavity 10. When the electromagnetic volume-fixing dispensing valve 27 is de-energized, the valve sealing ring 271 automatically resets under the action of the first spring 272, thus re-blocking the second seal 29 of the volume-fixing cavity. At this time, the first seal 28 of the volume-fixing cavity is open, allowing a predetermined amount of rinsing agent to flow from the rinsing agent volume-fixing cavity 10 to the rinsing agent dispensing area 9, and then from the rinsing agent dispensing area 9 to the rinsing agent dispensing outlet 30. The rinsing agent dispensing outlet 30 is connected to the dish and chopsticks working area, completing the automatic dispensing process of the rinsing agent.

[0039] Since the rinse aid is in liquid form, a float assembly 31 is installed in the rinse aid storage chamber 8 for liquid level detection. When the liquid level is low, the magnet on the float assembly 31 approaches the magnetic switch assembly 32, which then sends an electrical signal to the dishwasher control panel, thereby triggering the alarm program. The magnet is an existing part and is not shown in the accompanying drawings.

[0040] Connected to an external water source via inlet 35, the electromagnetic reversing valve body 14 can switch between the rinsing water path 13 and the pre-rinse water path 12. When the electromagnetic reversing valve body 14 is energized, the valve sealing rod 141 moves to the electromagnetic reversing valve port 39 under the action of electromagnetic force. At this time, the pre-rinse valve port 40 opens, and water flows from the inlet water path 11 along the pre-rinse valve port 40 to the pre-rinse water path 12. When de-energized, the valve sealing rod 141 moves to the pre-rinse valve port 40 under the action of the second spring 142; at this time, the pre-rinse water path 12 closes, and water flows from the inlet water path 11 along the dishwasher detergent water path port 41 to the rinsing water path 13. The pre-rinse water path 12 can pre-rinse the dishes and utensils in the work area, and the rinsing water path 13 can use water flow to dispense dishwasher detergent; here, there is no need to pour out the dishwasher detergent, reducing structural costs. Since the inclined outlet 38 is directly opposite the dishwasher detergent dispensing chamber 2, the dishwasher detergent dispensing chamber 2 can be rinsed using high-speed water flow. When water overflows from the dishwashing powder dispensing chamber 2, it is dispensed into the dish and chopstick work area through the liquid outlet 37. Residual water in the dishwashing powder dispensing chamber 2 can flow out through the drain hole 36, thus preventing water stains from remaining in the chamber.

[0041] Since the pre-wash water path 12 is connected to the piston pump liquid dispensing area 7, this ensures that the water flow can flush the dishwashing liquid dispensing port 24, preventing the high-viscosity dishwashing liquid residue from condensing and avoiding affecting the normal operation of the piston pump body 6.
