Description

Technical Field

[0001] This utility model relates to the field of dishwashing equipment technology, and more specifically to a water circuit control structure for a dishwasher distributor, a distributor, and 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, traditional dishwasher dispensers can only dispense dishwasher detergent and rinse aid, and the detergent needs to be refilled every time, which is inconvenient. Although a few products on the market have added a dishwashing liquid dispensing function, dishwashing liquid is relatively viscous and easily leaves residue in the dispensing channel, causing blockages and making it difficult to fully dispense into the dishwasher cavity. At the same time, the water circuit of existing dispensers usually only has a detergent rinsing channel and a pre-wash channel without detergent rinsing, and uses a separate solenoid valve for control. A separate solenoid valve is also needed to control the rinse aid dispensing, which is complex and costly. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a water circuit control structure for a dishwasher dispenser, a dispenser and a dishwasher, which can switch between rinsing powder and dishwashing liquid to prevent dishwashing liquid residue in its dispensing channel.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a water circuit control structure for a dishwasher dispenser. The dishwasher dispenser includes a dispensing box, and the water circuit control structure includes a solenoid valve disposed on the dispensing box, a water inlet channel disposed in the dispensing box, a first water circuit channel, and a second water circuit channel.

[0006] One side of the water inlet channel is provided with a first water passage hole that connects to the first water passage, and the other side is provided with a second water passage hole that connects to the second water passage; the first water passage connects to the dishwashing powder chamber, and the second water passage connects to the dishwashing liquid dispensing channel;

[0007] The valve core of the electromagnetic pump is fitted with a valve seal, which passes through the second water passage and the inlet water passage in sequence. The valve seal has a first sealing part. The first sealing part is located in the inlet water passage and, driven by the electromagnetic valve, blocks the first water passage or the second water passage to control the switching of the water passage.

[0008] This technical solution provides a water circuit control structure for a dishwasher dispenser, which includes a first water circuit channel for rinsing dishwashing powder and a second water circuit channel connected to a dishwashing liquid dispensing channel. A solenoid valve can switch between rinsing dishwashing powder and dishwashing liquid, so that after dispensing dishwashing liquid, the dishwashing liquid dispensing channel can be rinsed with water, which can prevent viscous dishwashing liquid from remaining in the dishwashing liquid dispensing channel and ensure that the dishwashing liquid can be smoothly dispensed into the inner cavity.

[0009] In a preferred embodiment, the dispensing box further includes a polishing agent reservoir, a polishing agent dispensing chamber, and a polishing agent dispensing channel. One side of the polishing agent dispensing chamber has an inlet port communicating with the polishing agent reservoir, and the other side has an outlet port communicating with the polishing agent dispensing channel.

[0012] This technology uses multiple water outlets arranged in a honeycomb pattern to ensure that the dishwasher detergent is quickly dispersed and placed into the dishwasher cavity. The total cross-sectional area of ​​the multiple water outlets is smaller than the cross-sectional area of ​​the main water inlet, which gives the water used to rinse the detergent a certain pressure, thus increasing the speed of rinsing the detergent.

[0013] In a preferred embodiment, the total cross-sectional area of ​​the multiple water outlets is 55% to 80% of the cross-sectional area of ​​the main water inlet, ensuring that the water used to rinse dish soap has sufficient pressure, resulting in faster and cleaner rinsing.

[0014] Preferably, the total cross-sectional area of ​​the multiple water outlets can be two-thirds of the cross-sectional area of ​​the main water inlet.

[0015] In a preferred embodiment, the bottom of the dishwashing powder chamber is connected to a dishwashing powder outlet located on the front of the dispensing box, and the bottom of the dishwashing powder chamber is inclined towards the side connected to the dishwashing powder outlet to prevent water accumulation.

[0016] In a preferred embodiment, the dispensing box is equipped with a peristaltic pump and a dishwashing liquid storage box; the dishwashing liquid storage box is connected to the dishwashing liquid dispensing channel via the peristaltic pump, and the end of the dishwashing liquid dispensing channel is equipped with a dishwashing liquid outlet.

[0017] In this technology, the dishwashing liquid storage box is used to store dishwashing liquid, which can be added once and used multiple times.

[0018] In a preferred embodiment, the dishwashing liquid reservoir is equipped with a liquid level detection device. This device can transmit the detected liquid level data to the dishwasher controller so that the user can monitor the remaining liquid level in real time and be reminded to add more dishwashing liquid in a timely manner.

[0019] In a preferred embodiment, the front of the dispensing box has a rotatable rinse aid dispensing cap and a detergent dispensing cap. The inside of the rinse aid dispensing cap is a rinse aid dispensing compartment, and the inside of the detergent dispensing cap is 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 via a dishwashing liquid transfer chamber within the dispensing box. When the detergent dispensing cap is closed, the dishwashing powder dispensing compartment is located within the dishwashing powder compartment. The dishwashing liquid transfer chamber is connected to a vent located on the back of the dispensing box, allowing for timely venting and improving the speed of dishwashing liquid dispensing.

[0021] The dispenser in this technology adopts the water circuit control structure of the dishwasher dispenser mentioned above. It can rinse the dishwashing liquid dispensing channel with water after the dishwashing liquid is dispensed, which can prevent viscous dishwashing liquid from remaining in the dishwashing liquid dispensing channel and ensure that the dishwashing liquid can be smoothly dispensed into the dishwasher cavity. Furthermore, the rinse aid dispensing and detergent water circuit switching are controlled by a single solenoid valve, which is simple in structure, low in cost, and has a large dispensing box capacity.

[0022] A dishwasher includes a dispenser as described in the above-described technical solution.

[0023] The dishwasher in this technology uses the aforementioned dispenser, which prevents viscous dishwashing liquid from remaining in the dishwashing liquid dispensing channel.

[0045] Reference Figure 1-12 This invention describes a water circuit control structure for a dishwasher distributor, a distributor, and a dishwasher according to an embodiment of the present invention. The water circuit control structure of the dishwasher distributor is applied to the dishwasher distributor, and the dishwasher can be a drawer-type dishwasher.

[0046] In one embodiment, such as Figure 1-12 As shown, a water circuit control structure for a dishwasher dispenser is provided. The dishwasher dispenser includes a dispensing box 1. The water circuit control structure includes a solenoid valve 2 disposed on the dispensing box 1, a water inlet channel 100 disposed in the dispensing box 1, a first water circuit channel 101 and a second water circuit channel 102.

[0047] The water inlet channel 100 has a first water passage hole on one side that connects to the first water passage 101, and a second water passage hole on the other side that connects to the second water passage 102; the first water passage 101 connects to the dishwashing powder chamber 111, and the second water passage 102 connects to the dishwashing liquid dispensing channel 107.

[0048] A valve seal 21 is fitted on the valve core 20 of the electromagnetic pump 2. The valve seal 21 passes through the second water passage 102 and the water inlet passage 100 in sequence. The valve seal 21 has a first sealing part 211. The first sealing part 211 is located in the water inlet passage 100 and, driven by the electromagnetic valve 2, blocks the first water passage or the second water passage to control the switching of the water passage.

[0049] Among them, the water inlet channel 100, the first water channel 101 and the second water channel 102 are independent channels separated from each other inside the dispensing box 1. The first water channel 101 and the second water channel 102 are located on both sides of the water inlet channel 100, and the first water hole and the second water hole are coaxially arranged.

[0050] Specifically, the dispensing box 1 is provided with 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; for example Figure 1As shown by the middle arrow, water can flow from the first water channel 101 to the dishwasher detergent chamber 111, rinse the detergent, and then flow out from the detergent rinsing outlet 114 into the dishwasher's interior. Alternatively, water can flow through the second water channel 102 to the dishwasher liquid dispensing channel 107, and then flow out from the dishwasher liquid outlet 115 into the dishwasher's interior, rinsing any residual dishwasher liquid in the dispensing channel 107. The dispensing box 1 is also equipped with a main water inlet 121 that communicates with the water inlet channel 100. Preferably, both the dishwasher liquid outlet 115 and the detergent rinsing outlet 114 are located on the front of the dispensing box 1, facing the dishwasher's interior.

[0051] 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.

[0052] This embodiment provides a water path control structure for a dishwasher dispenser, which includes a first water path channel 101 for rinsing dishwashing powder and a second water path channel 102 for not rinsing dishwashing powder. The second water path channel 102 is connected to the dishwashing liquid dispensing channel 107. By switching the water path, the dishwashing powder and dishwashing liquid can be rinsed. After dispensing the dishwashing liquid, the dishwashing liquid dispensing channel 107 can be rinsed with water to prevent viscous dishwashing liquid from remaining in the dishwashing liquid dispensing channel 107 and to ensure that the dishwashing liquid can be smoothly dispensed into the dishwasher cavity.

[0053] In this embodiment, the dispensing box 1 is further provided with a polishing agent storage chamber 105, a polishing agent dispensing chamber 104, and a polishing agent dispensing channel 103; one side of the polishing agent dispensing chamber 104 is provided with an inlet hole communicating with the polishing agent storage chamber 105, and the other side is provided with an outlet hole communicating with the polishing agent dispensing channel 103; the end of the polishing agent dispensing channel 103 is provided with a polishing agent outlet 116; the valve seal 21 passes through the polishing agent storage chamber 105, the polishing agent dispensing chamber 104, and the polishing agent dispensing channel 103 in sequence, and the valve seal 21 also has a second sealing part 212; the second sealing part 212 is located in the polishing agent dispensing chamber 104, and under the drive of the solenoid valve 2, it blocks the outlet hole or blocks the inlet hole to dispense polishing agent.

[0054] The detergent dispenser 1 is installed on the inner door of the dishwasher, and has a rotatable rinse aid dispenser cover 13. Inside the rinse aid dispenser cover 13 is a rinse aid dispensing chamber 130, which is connected to the rinse aid reservoir 105. The rinse aid reservoir 105, the rinse aid dispensing chamber 104, the rinse aid dispensing channel 103, the water inlet channel 100, the first water channel 101, and the second water channel 102 are independent of each other and are controlled by the dispenser. The partition inside the container 1 is separated; a partition is also provided between the second water channel 102 and the brightener dispensing channel 103. The partition has a through hole for the valve seal 21 to pass through. The discharge hole and the inlet hole are holes opened on the partitions on both sides of the brightener dispensing chamber 104. 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 container 1 by passing through the inlet hole, the discharge hole, the through hole and the second water hole in sequence.

[0055] 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 is composed of a dispensing box upper cover 11 and a dispensing box lower cover 12 that are snapped together, which is convenient for assembly and maintenance; the rinse aid outlet 116 is opened on the front of the dispensing box 1 and is used to dispense rinse aid into the dishwasher cavity.

[0056] Specifically, driven by the solenoid valve 2, when the second sealing part 212 blocks the discharge port, the inlet opens, and the finishing agent metering chamber 104 connects with the finishing agent storage chamber 105. The finishing agent in the finishing agent storage chamber 105 enters the finishing agent metering chamber 104 through the inlet. When the second sealing part 212 blocks the discharge port, the discharge port opens, and the finishing agent metering chamber 104 connects with the finishing agent dispensing channel 103. The finishing agent in the finishing agent metering chamber 104 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 second sealing part 212 to move back and forth to dispense a metered amount of finishing agent each time, thereby realizing the finishing agent dispensing.

[0057] The water circuit control structure of the dishwasher dispenser described above can control water circuit switching and rinse aid dispensing by sharing 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 water circuit switching and rinse aid dispensing separately, this simplifies the structure, reduces costs, and increases the capacity of the dispensing box 1.

[0058] In one embodiment of this invention, a level sensor is provided in the rinse aid reservoir 105 to detect the rinse aid level in real time and send the rinse aid level data to the dishwasher controller. If the level is too low, the user can be reminded to add rinse aid. The level sensor includes a float 1051 and a reed switch 1052.

[0059] Furthermore, the rinse aid dispensing chamber 104 can also be connected to a venting channel 122, which serves a bidirectional airflow function: when the gas inside the rinse aid dispensing chamber 104 expands due to heat, it is exhausted through the venting channel 122; when rinse aid is dispensed into the dishwasher cavity, air can also enter through the venting channel 122 to prevent the formation of a vacuum during dispensing; in addition, when rinse aid is added, the venting channel 122 can quickly expel gas, making the dispensing process faster and smoother. When the venting channel 122 is venting, the airflow path within the venting channel 122 is as follows: Figure 1 As indicated by the middle arrow, the outlet of the vent 122 is located on the back of the dispensing box 1. Since the back of the dispensing box 1 is located outside the inner door of the dishwasher, rather than inside the dishwasher cavity, when the dispensing box 1 is installed on the inner door, the vent 122 is connected to the atmosphere outside the inner door. This allows for smoother liquid addition and also prevents the vent 122 from drawing in high-temperature water vapor from the dishwasher cavity, which would otherwise cause condensation.

[0060] In this embodiment, the top of the dishwashing powder chamber 111 is provided with a plurality of water outlet holes 1110 arranged in a honeycomb pattern, and the plurality of water outlet holes 1110 are connected to the first water channel 101; the water inlet channel 101 is connected to the main water inlet 121; the total cross-sectional area of ​​the plurality of water outlet holes 1110 is smaller than the cross-sectional area of ​​the main water inlet 121.

[0061] The main water inlet 121 can be located on the side of the dispensing box 1.

[0062] The above embodiment, by employing multiple water outlets 1110 arranged in a honeycomb pattern, ensures that the dishwashing powder is quickly dispersed and placed into the dishwasher cavity. Furthermore, the total cross-sectional area of ​​the multiple water outlets 1110 is smaller than the cross-sectional area of ​​the main water inlet 121, which allows the water used to rinse the dishwashing powder to have a certain pressure, thereby increasing the speed of rinsing the dishwashing powder.

[0063] In this embodiment, the total cross-sectional area of ​​the multiple water outlets 1110 is 55% to 80% of the cross-sectional area of ​​the main water inlet 121, such as 55%, 60%, 65%, 70%, 80%, etc., which can ensure that the water used to rinse dish soap has sufficient pressure, rinsing the dish soap faster and rinsing it cleaner.

[0064] Preferably, the total cross-sectional area of ​​the plurality of water outlet holes 1110 can be two-thirds of the cross-sectional area of ​​the main water inlet 121.

[0065] In this embodiment, the bottom of the dishwashing powder chamber 111 is connected to the dishwashing powder outlet 114 located on the front of the dispensing box 1, and the bottom of the dishwashing powder chamber 111 is inclined to the side connected to the dishwashing powder outlet 114 to prevent water accumulation.

[0066] The rinse aid outlet 116, the dishwashing liquid outlet 115, and the dishwashing powder outlet 114 can all be located on the front of the dispensing box 1, that is, the side facing the inner cavity of the dishwasher. The rinse aid outlet 116 and the dishwashing liquid outlet 115 are adjacent to each other, and the dishwashing powder outlet 114 is located above the former two.

[0067] In practice, water enters the dishwashing powder chamber 111 through the first water channel 101 to rinse the dishwashing powder, and finally flows out from the dishwashing powder outlet 114 into the dishwasher cavity; dishwashing liquid can enter the dishwashing liquid dispensing channel 107 from the dishwashing liquid storage box 3 through the peristaltic pump 4, and finally flow out from the dishwashing liquid outlet 115.

[0068] 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, and the end of the dishwashing liquid dispensing channel 107 is provided with a dishwashing liquid outlet 115.

[0069] The dishwashing liquid storage box 3 can be connected to the dishwashing liquid dispensing compartment 141 on the dispensing box 1 to store dishwashing liquid, which can be added once and used multiple times.

[0070] 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 through the liquid extraction pipe 41, and the outlet is connected to the dishwashing liquid dispensing channel 107 through the liquid outlet pipe 42.

[0071] In this embodiment, the dishwashing liquid storage box 3 is equipped with a liquid level detection device.

[0072] The dishwashing liquid storage box 3 includes an upper storage box 31 and a lower storage box 32. The liquid level detection device is located in the cavity formed by the upper storage box 31 and the lower storage box 32. The liquid level detection device includes a storage box float 33 and a storage box reed switch 34.

[0073] Specifically, the liquid level detection device can transmit the detected dishwashing liquid level data to the dishwasher controller so that users can monitor the remaining amount of dishwashing liquid in real time and be reminded to add dishwashing liquid in a timely manner.

[0074] 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.

[0075] The rinse aid dispensing compartment 130 is connected to the rinse aid storage chamber 105. The dishwashing liquid dispensing compartment 141 is connected to the dishwashing liquid storage box 3 through the dishwashing liquid transfer chamber 106 in the dispensing box 1. When the detergent dispensing cap 14 is closed, the dishwashing powder dispensing compartment 142 is located in the dishwashing powder chamber 111. The dishwashing liquid transfer chamber 106 is connected to a vent 123 located on the back of the dispensing box 1, which can release air in time and improve the dispensing speed of dishwashing liquid.

[0076] Preferably, a rinse aid seal is provided between the rinse aid dispensing cap 13 and the dispensing box 1, and a detergent seal is provided between the detergent dispensing cap 14 and the dispensing box 1, which serves to seal the contents.

[0077] 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 111, which contain a rinse aid dispensing chamber 130, a dishwashing liquid dispensing chamber 141, and a dishwashing powder dispensing chamber 142. The filling tube of the rinse aid dispensing chamber 130 passes through the outlet of the rinse aid chamber 113 and is connected to the rinse aid storage chamber 105. The filling tube of the dishwashing liquid dispensing chamber 141 passes through the outlet of the dishwashing liquid chamber 112 and is connected to the dishwashing liquid transfer chamber 106. The dishwashing liquid transfer chamber 106 is connected to the dishwashing liquid storage box 3. The vent 123 serves a two-way airflow function: when the gas inside the dishwashing liquid transfer chamber 106 expands due to heat, it is vented through the vent 123; when the dishwashing liquid transfer chamber 106 delivers dishwashing liquid to the dishwashing liquid storage box 3, air can also enter through the vent 123 to prevent the formation of a vacuum; furthermore, when adding dishwashing liquid, the vent 123 can quickly expel gas, making the addition faster and smoother. When venting, the airflow direction is as follows: Figure 1 As indicated by the middle arrow.

[0078] Specifically, open the rinse aid dispensing cap 13 and pour 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 105 for storage. At the same time, open the detergent dispensing cap 14 and pour the dishwashing liquid / dishwashing powder into the dishwashing liquid dispensing chamber 141 / dishwashing powder dispensing chamber 142. Close the detergent dispensing cap 14 so that the dishwashing powder in the dishwashing powder dispensing chamber 142 is located in the dishwashing powder chamber 111. The bottom surface of the dishwashing powder dispensing chamber 142 may have multiple small holes to allow the rinsing water to flow out into the dishwashing powder chamber 111, and then out into the dishwasher cavity through the rinsing water outlet 114. The dishwashing liquid first flows from the dishwashing liquid dispensing chamber 141 into the dishwashing liquid transfer chamber 106 in the dispensing box 1, and then flows through the dishwashing liquid transfer chamber 106 into the dishwashing liquid storage box 3.

[0079] In practice, when the dispensing box 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 123 is connected to the atmosphere outside the inner door, which makes the addition of dishwashing liquid smoother, while preventing the vent 123 from sucking in the high-temperature water vapor in the inner cavity of the dishwasher to produce condensation.
