Description

Technical Field

[0001] This utility model relates to the field of dishwashing equipment technology, and more specifically to a rinse aid dispensing structure, dispenser, and dishwasher for a dishwasher. Background Technology

[0002] As living standards continue to improve, household dishwashers, as a hands-free appliance, are becoming increasingly popular among consumers. The dishwasher dispenser is a key component in a dishwasher used to control the amount of detergent added, and it has a direct impact on the washing results.

[0003] However, existing dishwasher dispensers typically use one solenoid valve to control the rinse aid dispensing channel and another solenoid valve to control the rinse powder water path. This requires two independent solenoid valves to separately implement rinse aid dispensing and water path control, resulting in a heavy load, complex structure, and large space occupation, leading to low space utilization and small capacity of the dispenser. Utility Model Content

[0004] To overcome the aforementioned shortcomings of the prior art, this utility model provides a rinse aid dispensing structure, dispenser, and dishwasher that can control the rinse aid dispensing and water circuit structure through a solenoid valve, thereby simplifying the structure and reducing costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dishwasher rinse aid dispensing structure, including a dispensing box;

[0006] The dispenser box has a rinse aid reservoir, a rinse aid metering dispenser, a rinse aid dispensing channel, and a water channel structure. One side of the rinse aid metering dispenser is provided with an inlet that connects to the rinse aid reservoir, and the other side is provided with an outlet that connects to the rinse aid dispensing channel. The end of the rinse aid dispensing channel is provided with a rinse aid outlet.

[0007] The dispensing box is also equipped with a solenoid valve, and the valve core of the solenoid pump is fitted with a valve seal. The valve seal passes through the brightener storage chamber, the brightener metering chamber, the brightener dispensing channel and the water circuit structure in sequence.

[0008] The valve seal has a first sealing part and a second sealing part. The first sealing part is located in the brightener metering chamber and, driven by the solenoid valve, blocks the discharge port or the inlet port to dispense brightener. The second sealing part is located in the water circuit structure and, driven by the solenoid valve, controls the water circuit switching.

[0009] Preferably, the valve core of the solenoid valve is equipped with a spring, which helps to reset the valve core, buffer impact force, adjust the sensitivity of action, save energy and protect the environment, and improve reliability.

[0010] This technical solution provides a dishwasher rinse aid dispensing structure that allows the rinse aid dispensing and water circuit structure to share a single solenoid valve control via a valve seal having a first sealing part and a second sealing part. Compared to traditional products that use two solenoid valves to control the rinse aid dispensing and water circuit separately, this simplifies the structure, reduces costs, and increases the capacity of the dispensing box.

[0011] In a preferred embodiment, the water circuit structure includes an inlet channel, a first water circuit channel, and a second water circuit channel. The first water circuit channel is connected to the dishwashing powder chamber to rinse the dishwashing powder, and the second water circuit channel is connected to the dishwashing liquid dispensing channel. One side of the inlet channel is provided with a first water inlet hole connected to the first water circuit channel, and the other side is provided with a second water inlet hole connected to the second water circuit channel. A valve seal also passes through the second water circuit channel and the inlet channel in sequence. The second sealing part is located in the inlet channel and, driven by the solenoid valve, blocks the first water inlet hole or blocks the second water inlet hole to control the switching of the water circuit.

[0012] This technology connects the second water channel (which does not rinse the dishwashing powder) to the dishwashing liquid dispensing channel. After dispensing the dishwashing liquid, the dispensing channel can be rinsed with water to prevent viscous dishwashing liquid residue from remaining in the channel, ensuring that the dishwashing liquid can be smoothly dispensed into the dishwasher cavity. At the same time, the water channel switching and rinse aid dispensing are controlled by a single solenoid valve, which simplifies the structure and reduces costs.

[0013] In a preferred embodiment, the dispensing box is equipped with a peristaltic pump and a dishwashing liquid reservoir; the dishwashing liquid reservoir is connected to the dishwashing liquid dispensing channel via the peristaltic pump. Preferably, the dishwashing liquid reservoir may be equipped with a liquid level detection device, which can transmit the detected dishwashing liquid level data to the dishwasher controller so that the user can monitor the remaining dishwashing liquid level in real time and be promptly reminded to add dishwashing liquid.

[0014] In a preferred embodiment, the front of the dispensing box is provided with a rinse aid outlet, a dishwashing liquid outlet, and a dishwashing powder outlet. The dishwashing liquid outlet is connected to the dishwashing liquid dispensing channel, and the dishwashing powder outlet is connected to the dishwashing powder chamber.

[0015] In a preferred embodiment, the front of the dispensing box is provided with a rotatable rinse aid dispensing cap and a detergent dispensing cap. The inside of the rinse aid dispensing cap is provided with a rinse aid dispensing compartment, and the inside of the detergent dispensing cap is provided with a dishwashing powder dispensing compartment and a dishwashing liquid dispensing compartment. The rinse aid dispensing compartment is connected to the rinse aid reservoir, and the dishwashing liquid dispensing compartment is connected to the dishwashing liquid reservoir. When the detergent dispensing cap is closed, the dishwashing powder dispensing compartment is located inside the dishwashing powder compartment.

[0016] In this technology, the dispensing box is equipped with a rotatable rinse aid dispensing cap and a detergent dispensing cap, making it convenient for users to add rinse aid and detergent. The rinse aid is stored in the rinse aid reservoir, and the detergent is stored in the detergent reservoir. One addition can be used multiple times, making it more convenient to use.

[0017] In a preferred embodiment, a level sensor is provided in the polishing agent reservoir to detect the polishing agent level in real time.

[0018] In a preferred embodiment, the rinse aid dispensing chamber is connected to a vent located on the back of the dispensing box, which allows for timely venting and helps to increase the dispensing speed of the rinse aid.

[0019] A dispenser comprising a rinse aid dispensing structure for a dishwasher as described in any of the above technical solutions.

[0020] The dispenser in this technology adopts the rinse aid dispensing structure of the dishwasher mentioned above, which can share a single solenoid valve to control both the rinse aid dispensing and the detergent water circuit. It has a simple structure, low cost, and large capacity.

[0021] A dishwasher includes a dispenser as described in the above-described technical solution.

[0022] The dishwasher in this technology uses the aforementioned dispenser, which simplifies the structure, reduces costs, and provides a large dispensing capacity.

[0023] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are:

Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0041] Reference Figure 1-9 This invention describes a dishwasher rinse aid dispensing structure, dispenser, and dishwasher according to an embodiment of the present invention. The rinse aid dispensing structure can be applied to the dishwasher dispenser, and the dishwasher can be a drawer-type dishwasher.

[0042] In one embodiment, such as Figure 1-9 As shown, a dishwasher rinse aid dispensing structure includes a dispensing box 1;

[0043] The interior of the dispensing box 1 has a rinse aid storage chamber 101, a rinse aid metering dispensing chamber 102, a rinse aid dispensing channel 103, and a water channel structure; one side of the rinse aid metering dispensing chamber 102 is provided with an inlet hole that connects to the rinse aid storage chamber 101, and the other side is provided with an outlet hole that connects to the rinse aid dispensing channel 103; the end of the rinse aid dispensing channel 103 is provided with a rinse aid outlet 116.

[0044] The dispensing box 1 is also equipped with a solenoid valve 2. The valve core 20 of the solenoid pump 2 is fitted with a valve seal 21. The valve seal 21 passes through the brightener storage chamber 101, the brightener metering dispensing chamber 102, the brightener dispensing channel 103 and the water circuit structure in sequence.

[0045] The valve seal 21 has a first sealing part 211 and a second sealing part 212. The first sealing part 211 is located in the brightener metering chamber 102 and blocks the discharge port or the inlet port to dispense brightener under the drive of the solenoid valve 2. The second sealing part 212 is located in the water circuit structure and controls the water circuit switching under the drive of the solenoid valve 2.

[0046] The dispenser box 1 is installed on the inner door of the dishwasher, and the dispenser box 1 is equipped with a rotatable rinse aid dispenser cover 13. The inside of the rinse aid dispenser cover 13 is a rinse aid dispensing chamber 130, which is connected to the rinse aid reservoir 101. The rinse aid reservoir 101, the rinse aid dispensing chamber 102, the rinse aid dispensing channel 103, and the water circuit structure are independent of each other and are separated by a partition inside the dispenser box 1. The discharge port and the inlet port are opened on the partitions on both sides of the rinse aid dispensing chamber 102, and the discharge port and the inlet port are coaxially arranged so that the valve seal 21 can pass through. The rinse aid outlet 116 is opened on the front of the dispenser box 1 and is used to dispense rinse aid into the inner cavity of the dishwasher.

[0047] In practice, the valve seal 21 is an integrally formed elastic component, which can be made of elastic materials such as silicone or rubber; the dispensing box 1 consists of a dispensing box upper cover 11 and a dispensing box lower cover 12 that are fastened together, which facilitates assembly and maintenance.

[0048] Specifically, driven by the solenoid valve 2, when the first sealing part 211 blocks the discharge port, the inlet opens, and the finishing agent metering chamber 102 connects with the finishing agent storage chamber 101. The finishing agent in the finishing agent storage chamber 101 enters the finishing agent metering chamber 102 through the inlet. When the first sealing part 211 blocks the discharge port, the discharge port opens, and the finishing agent metering chamber 102 connects with the finishing agent dispensing channel 103. The finishing agent in the finishing agent metering chamber 102 enters the finishing agent dispensing channel 103 through the discharge port and flows out from the finishing agent outlet 116. The above-mentioned finishing agent dispensing structure uses the solenoid valve 2 to drive the first sealing part 211 to move back and forth to dispense a metered amount of finishing agent each time, thereby realizing the finishing agent dispensing.

[0049] Preferably, the valve core 20 of the solenoid valve 2 is provided with a spring 22, which plays a role in assisting the valve core 20 to reset, buffering impact force, adjusting the sensitivity of action, saving energy and protecting the environment, and improving reliability.

[0050] This embodiment provides a dishwasher rinse aid dispensing structure that allows the rinse aid dispensing and water circuit structure to be controlled by a single solenoid valve 2 through a valve seal 21 having a first sealing part 211 and a second sealing part 212. Compared with traditional products that use two solenoid valves to control the rinse aid dispensing and water circuit separately, this simplifies the structure, reduces costs, and increases the capacity of the dispensing box 1.

[0051] In one embodiment of this invention, the first sealing part 211 includes a sealing boss and a first conical disc disposed around the bottom edge of the sealing boss. The sealing boss is used to seal the discharge hole, and the first conical disc is used to seal the inlet hole. In a specific implementation, in order to facilitate the installation of the valve seal 21, the inner diameter of the inlet hole is larger than the inner diameter of the discharge hole. Under the drive of the solenoid valve 2, the first sealing part 211 can move forward so that the sealing boss is interference-fitted with the discharge hole to seal the discharge hole. The first sealing part 211 can also move backward so that the first conical disc completely covers the inlet hole to seal the inlet hole.

[0052] The above-described embodiments enhance the sealing effect, ensuring a tight seal for both the inlet and outlet ports. In addition to the above embodiments, the first sealing part 211 can also employ other structures to achieve the sealing of the inlet and outlet ports.

[0053] In this embodiment, the water channel structure includes a water inlet channel 104, a first water channel 105 and a second water channel 106. The first water channel 105 is connected to the dishwashing powder chamber 111 to rinse the dishwashing powder, and the second water channel 106 is connected to the dishwashing liquid dispensing channel 107.

[0054] One side of the water inlet channel 104 is provided with a first water passage hole that connects to the first water passage 105, and the other side is provided with a second water passage hole that connects to the second water passage 106.

[0055] The valve seal 21 also passes through the second water passage 106 and the water inlet passage 104 in sequence. The second sealing part 212 is located in the water inlet passage 104 and blocks the first water passage or the second water passage under the drive of the solenoid valve 2 to control the switching of the water passage.

[0056] The water inlet channel 104, the first water channel 105, and the second water channel 106 are independent channels separated from each other inside the dispensing box 1. The first water channel 105 and the second water channel 106 are located on both sides of the water inlet channel 104. A partition is also provided between the second water channel 106 and the brightener dispensing channel 103. The partition has a through hole for the valve seal 21 to pass through. The first water hole, the second water hole, the through hole, the discharge hole, and the inlet hole are arranged coaxially in sequence. The valve seal 21 is installed in the dispensing box 1 by passing through the inlet hole, the discharge hole, the through hole, and the second water hole in sequence.

[0057] Specifically, inside the dispensing box 1, along the installation direction of the valve seal 21, are sequentially arranged a rinse aid reservoir 101, a rinse aid dispensing chamber 102, a rinse aid dispensing channel 103, a second water channel 106, a water inlet channel 104, and a first water channel 105. The first sealing part 211 is located inside the rinse aid dispensing chamber 102, and the second sealing part 212 is located inside the water inlet channel 104. The rinse aid dispensing and water channel switching can be controlled by the same solenoid valve 2. Simultaneously, the dispensing box 1 is equipped with a rinse aid outlet 116, a dishwashing liquid outlet 115, and a dishwashing powder outlet 114. The water flow direction in the first water channel 105 is as follows: Figure 1 As shown by the middle arrow, water flows from the first water channel 105 to the dishwashing powder chamber 111, rinses the dishwashing powder, and then flows out from the dishwashing powder outlet 114 into the inner cavity of the dishwasher; the dispensing box 1 is also provided with a main water inlet 121 that is connected to the water inlet channel 104.

[0058] In the above embodiment, by connecting the second water channel 106 (which does not rinse dish powder) to the dishwashing liquid dispensing channel 107, the dishwashing liquid dispensing channel 107 can be rinsed with water after the dishwashing liquid is dispensed, preventing viscous dishwashing liquid from remaining in the dishwashing liquid dispensing channel 107 and ensuring that the dishwashing liquid can be smoothly dispensed into the dishwasher cavity; at the same time, the water channel switching and the rinse aid dispensing are controlled by a single solenoid valve 2, which simplifies the structure and reduces costs.

[0059] In one embodiment of this invention, the second sealing part 212 is located at the foremost end of the valve seal 21. The second sealing part 212 includes a sealing protrusion and a second conical disc surrounding the bottom edge of the sealing protrusion. The sealing protrusion is used to seal the first water passage hole, and the second conical disc is used to seal the second water passage hole. In a specific implementation, to facilitate the installation of the valve seal 21, the inner diameter of the second water passage hole is generally larger than the inner diameter of the first water passage hole. Under the drive of the solenoid valve 2, the second sealing part 212 moves forward so that the sealing protrusion is press-fitted with the first water passage hole to seal the first water passage hole, and the second sealing part 212 moves backward so that the second conical disc completely covers the second water passage hole to seal the second water passage hole.

[0060] The above-described embodiments enhance the sealing effect, ensuring a tight seal for both the first and second water passages. Besides the above embodiments, the second sealing part 212 can also employ other structures to achieve the sealing. In specific implementations, the outer diameter of the second conical disc is smaller than the outer diameter of the first conical disc.

[0061] In this embodiment, the dispensing box 1 is equipped with a peristaltic pump 4 and a dishwashing liquid storage box 3; the dishwashing liquid storage box 3 is connected to the dishwashing liquid dispensing channel 107 through the peristaltic pump 4.

[0062] The dishwashing liquid storage box 3 is connected to the dishwashing liquid dispensing compartment 141 on the dispensing box 1 to store dishwashing liquid, allowing for multiple uses from a single addition. Specifically, the peristaltic pump 4 and the dishwashing liquid storage box 3 are located on the back of the dispensing box 1. The inlet of the peristaltic pump 4 is connected to the dishwashing liquid storage box 3 via a suction pipe 41, and the outlet is connected to the dishwashing liquid dispensing channel 107 via a discharge pipe 42.

[0063] In the above embodiment, dishwashing liquid is provided by peristaltic pump 4 and dishwashing liquid storage box 3. The dishwashing liquid can be stored in dishwashing liquid storage box 3, with a large storage capacity, which is convenient for multiple uses after one filling.

[0064] Preferably, the dishwashing liquid storage box 3 may be equipped with a liquid level detection device, which can transmit the detected liquid level data of the dishwashing liquid to the controller of the dishwasher so that the user can keep track of the remaining amount of dishwashing liquid in real time and remind the user to add dishwashing liquid in a timely manner.

[0065] In this embodiment, the front of the dispensing box 1 is provided with a rinse aid outlet 116, a dishwashing liquid outlet 115, and a dishwashing powder outlet 114. The dishwashing liquid outlet 115 is connected to the dishwashing liquid dispensing channel 107, and the dishwashing powder outlet 114 is connected to the dishwashing powder chamber 111.

[0066] The front of the dispensing box 1 faces the inner cavity of the dishwasher. The rinse aid outlet 116 and the dishwashing liquid outlet 115 are adjacent to each other, and the rinsing powder outlet 114 is located above the former two. In specific implementation, water enters the dishwashing powder chamber 111 through the first water channel 105 to rinse the dishwashing powder, and finally flows out from the rinsing powder outlet 114 into the inner cavity of the dishwasher. The dishwashing liquid enters the dishwashing liquid dispensing channel 107 from the dishwashing liquid storage box 3 through the peristaltic pump 4, and finally flows out from the dishwashing liquid outlet 115.

[0067] The above embodiment is equipped with a rinse aid outlet 116, a dishwashing liquid outlet 115, and a dishwashing powder outlet 114, which can dispense rinse aid, dishwashing liquid, and dishwashing powder. It is compatible with dishwashing liquid and is more convenient to use.

[0068] In this embodiment, the front of the dispensing box 1 is provided with a rotatable rinse aid dispensing cover 13 and a detergent dispensing cover 14. The inside of the rinse aid dispensing cover 13 is provided with a rinse aid dispensing chamber 130, and the inside of the detergent dispensing cover 14 is provided with a dishwashing powder dispensing chamber 142 and a dishwashing liquid dispensing chamber 141.

[0069] The rinse aid dispensing chamber 130 is connected to the rinse aid reservoir 101, and the dishwashing liquid dispensing chamber 141 is connected to the dishwashing liquid reservoir 3. When the detergent dispensing cap 14 is closed, the dishwashing powder dispensing chamber 142 is located inside the dishwashing powder reservoir 111.

[0070] The front of the dispensing box 1 is provided with a rinse aid chamber 113, a dishwashing liquid chamber 112, and a dishwashing powder chamber 112, which contain a rinse aid dispensing compartment 130, a dishwashing liquid dispensing compartment 141, and a dishwashing powder dispensing compartment 142. The filling tube of the rinse aid dispensing compartment 130 passes through the outlet of the rinse aid chamber 113 and is connected to the rinse aid storage chamber 101. The filling tube of the dishwashing liquid dispensing compartment 141 passes through the outlet of the dishwashing liquid chamber 112 and is connected to the dishwashing liquid transfer chamber in the dispensing box 1. The dishwashing liquid transfer chamber is connected to the dishwashing liquid storage box 3.

[0071] Preferably, a sealing element is provided between the rinse aid dispensing cap 13, the detergent dispensing cap 14 and the dispensing box 1 to achieve a sealing function.

[0072] In practice, the user opens the rinse aid dispensing cap 13 and pours the rinse aid into the rinse aid dispensing chamber 130. The rinse aid flows from the rinse aid dispensing chamber 130 into the rinse aid storage chamber 101 for storage, allowing it to be used multiple times after one addition. The user opens the detergent dispensing cap 14 and pours the dishwashing liquid / dishwashing powder into the dishwashing liquid dispensing chamber 141 / dishwashing powder dispensing chamber 142. The dishwashing liquid flows into the dishwashing liquid storage box 3 for storage, allowing it to be used multiple times after one addition. After the detergent dispensing cap 14 is closed, the dishwashing powder in the dishwashing powder dispensing chamber 142 rinses the dishwashing powder in the dishwashing powder chamber 111.

[0073] In this technology, the dispensing box 1 is equipped with a rotatable rinse aid dispensing cap 13 and a detergent dispensing cap 14, which makes it convenient for users to add rinse aid and detergent. The rinse aid is stored in the rinse aid storage chamber 101 and the dishwashing liquid storage box 3 stores the dishwashing liquid. One addition can be used multiple times, making it more convenient to use.

[0074] In this embodiment, a level sensor is provided in the polishing agent reservoir 101 to detect the polishing agent level in real time.

[0075] The liquid level sensor may include a float 1011 and a reed switch 1012; the liquid level sensor is electrically connected to the controller of the dishwasher.

[0076] Specifically, the level sensor is used to detect the level of the rinse aid reservoir and send the rinse aid level data to the dishwasher controller. If the level is too low, it can remind the user to add more rinse aid.

[0077] In this embodiment, the polishing agent dispensing chamber 102 is connected to a vent 122 located on the back of the dispensing box 1, which can release air in time and help improve the dispensing speed of polishing agent.

[0078] The vent 122 serves a two-way airflow function: when the gas inside the rinse aid dispensing chamber 102 expands due to heat, it is exhausted through the vent 122; when rinse aid is dispensed into the dishwasher cavity, air can also enter through the vent 122 to prevent a vacuum from forming during dispensing; furthermore, when rinse aid is added, the vent 122 can quickly expel gas, making the dispensing process faster and smoother. When the vent 122 is venting, the airflow path between the rinse aid dispensing chamber 102 and the vent 122 is as follows: Figure 1 As indicated by the middle arrow, the vent 122 is positioned above the brightener dispensing chamber 102.

[0079] Specifically, when the dispenser 1 is installed on the inner door of the dishwasher, its back is located inside the inner door, not in the inner cavity of the dishwasher. The vent 122 is connected to the atmosphere outside the inner door, which makes the rinse aid dispensing smoother, while preventing the vent 122 from sucking in the high-temperature water vapor in the inner cavity of the dishwasher to produce condensation.

[0080] Based on the above embodiments, the working principle of the brightening agent dispensing structure is as follows: the valve seal 21 adopts a two-stage sealing structure for control, the first sealing part 211 controls the dispensing of brightening agent, and the second sealing part 212 controls the water circuit switching.

[0081] When the solenoid valve 2 is closed, the valve core 20 is in the first position, the first sealing part 211 blocks the discharge hole, and the second sealing part 212 blocks the first water passage. At this time, the dishwashing liquid dispensing channel 103 is in a sealed state, the water flows through the second water channel 106, and the dishwashing powder is not rinsed out, but flows out from the dishwashing liquid outlet 115.

[0082] When the dishwasher needs to be dispensed with dishwashing liquid, the peristaltic pump 4 draws the dishwashing liquid from the dishwashing liquid reservoir 3 into the second water channel 106 on the dispensing box 1, and finally flows out into the dishwasher cavity through the dishwashing liquid outlet 115. The second water channel 106 is connected to the dishwashing liquid dispensing channel 107. When the water flows through the second water channel 106, it can flush the viscous dishwashing liquid into the dishwasher cavity, preventing blockage of the dishwashing liquid outlet 115.

[0083] When the dishwasher needs to rinse the detergent, the solenoid valve 2 opens, causing the valve seal 21 to move to the second position. The first sealing part 211 blocks the feed hole, and the second sealing part 212 blocks the second water passage. At this time, the water circuit switches to the first water circuit channel 105 to rinse the detergent. The rinsed detergent flows out from the detergent outlet 114 into the inner cavity of the dishwasher.

[0084] After the dishwashing powder is rinsed off, the solenoid valve 2 opens and closes according to the rinse aid dispensing requirements, repeating the process of the rinse aid entering the rinse aid dispensing chamber 101 from the rinse aid reservoir 101 and then entering the rinse aid dispensing channel 103, thus dispensing the rinse aid.

[0085] In one embodiment, such as Figure 7-9 As shown, this utility model provides a dispenser 200, which includes a dishwasher rinse aid dispensing structure as described in any of the above embodiments.
