Detailed Description
The technical scheme of the application is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1-4, a dishwashing liquid storage container comprises a container body 110 and a storage cavity 120 arranged in the container body 110, wherein a liquid outlet 130 is arranged at the top of the container body 110, and the liquid outlet 130 is communicated with the storage cavity 120; a guide plate is transversely arranged in the storage cavity 120, and at least one guide plate 121 is arranged; the upper end of the deflector 121 is inclined toward the top of the container body 110; the baffle 121 divides the storage cavity into a plurality of layers of cavities from top to bottom; the upper end of the guide plate 121 is provided with a liquid passing notch 122; when there are multiple guide plates 121, the multiple guide plates 121 are stacked up and down, and the upper ends of the guide plates 121 that are adjacent up and down are staggered left and right.
Because the volume of the dish washing liquid storage container is larger than that of the existing dish washing liquid storage container, the dish washing liquid is sticky colloidal liquid, and the fluidity is poor. The dish washing liquid is stored and is in an upright state like the cabinet door of the dish washing machine, the dish washing liquid storage container can be toppled along with the cabinet door every time the user opens the cabinet door of the dish washing machine, but the operation time of opening the door every time is not particularly long, so that the dish washing liquid in the dish washing liquid storage container is likely to flow out of the liquid outlet 130 smoothly, especially when the dish washing liquid in the dish washing liquid storage container is in the bottom of the dish washing liquid storage container along with the use of less and less, the dish washing liquid is more difficult to ensure that the toppling state is smoothly flowing out every time. Therefore, a guide plate 121 with a specific inclined structure is arranged in the storage cavity of the dishwashing liquid storage container, the guide plate 121 divides the storage cavity into an upper multi-layer space and a lower multi-layer space, and dishwashing liquid flows along the bottom surface of the storage cavity towards the top of the dishwashing liquid storage container, namely towards the liquid outlet 130 each time the dishwashing liquid storage container is toppled; when the dishwashing liquid in the lower cavity is blocked by the upper guide plate 121, the dishwashing liquid can flow to the liquid passing notch 122 along the inclined direction of the guide plate 121 and enter the upper cavity through the liquid passing notch 122; when the cabinet door is closed again, i.e. the storage cavity 120 is raised, most of the dishwashing liquid in each layer of cavity is caught by the deflector 121; according to the principle, each time the dish washing liquid storage container is subjected to dumping operation, the dish washing liquid in the lower cavity of the dish washing liquid storage container gradually flows into the upper cavity; finally, the dishwashing liquid in the storage cavity 120 can flow out from the liquid outlet 130 more quickly and smoothly, and the use rate of the dishwashing liquid can be increased, so that the use cost is saved.
How many guide plates 121 are specifically arranged in the storage cavity 120 to divide the storage cavity 120 into how many layers of cavities, the toppling degree of the dishwashing liquid storage container and the flowing condition of the dishwashing liquid in the dishwashing liquid storage container are specifically determined according to the opening of a specific dishwasher door, and the person skilled in the art can make corresponding adjustment according to the needs. As shown in fig. 3 and fig. 4, the liquid outlet 130 of the dish washing liquid storage container is disposed at the left side of the top, two guide plates 121 are disposed in the storage cavity 120 of the dish washing liquid storage container, the two guide plates 121 are stacked up and down, and the liquid passing notch 122 of the guide plate 121 on the upper layer and the liquid passing notch 122 of the guide plate 121 on the lower layer are staggered in the vertical direction and are respectively disposed at two sides of the storage cavity 120.
Specifically, the storage cavity 120 has a capacity greater than 100ML; as shown in fig. 2, the lower portion of the storage chamber 120 has a smaller thickness than the upper portion. In the prior art, the washing consumables put into the dish washing machine mainly comprise dish washing powder and a dish brightening agent. The dish washing powder is solid and powdery, is mainly used for washing consumables for washing tableware, and is added according to the washing amount of the tableware, so that the required adding amount is relatively large; the dish-brightening agent is used for further cleaning the washed tableware, so that the tableware is brighter and more attractive, and the required throwing amount is smaller. The liquid dishwashing liquid stored in the dishwashing liquid storage container is used for replacing dishwashing powder with dishwashing liquid, the dishwashing consumption of each time can be further improved, and the existing container structure for putting small-dose washing consumables can not meet the requirements of storage and putting of the dishwashing liquid at all; in addition, compared with the use cost of the dishwashing powder dishwashing liquid, the dishwashing powder dishwashing liquid is lower, the purchasing is more convenient, the washing capacity of the dishwashing liquid is stronger, and the dishwashing powder dishwashing liquid can be suitable for washing more different kinds of tableware such as Chinese meal, western meal and the like. The capacity of the dishwashing liquid storage container is required to be more than 100ML, preferably 300ML to 600ML, to satisfy multiple dishwashing operations of the dishwasher. The lower portion of the storage cavity 120 is narrower, so that at least one of the front and rear sides of the storage cavity 120 is inclined, as shown in fig. 2, and the rear side of the storage cavity 120 is inclined, so that the dishwashing liquid can flow from the bottom to the upper chamber more quickly.
As shown in fig. 3 and 4, the dishwashing liquid storage container body 110 is a rectangular hollow plate-shaped container, and the liquid passing notch 122 is flush with the left or right side of the storage cavity. The dishwashing liquid in the dishwashing liquid storage container is flowed by a pouring operation, which is referenced along the interior of the storage cavity 120 or the deflector 121 as a path. When the dishwashing liquid flows into the upper-layer cavity from the liquid passing notch 122, the dishwashing liquid can more quickly flow into the upper-layer cavity along the corresponding side surface because the liquid passing notch 122 is arranged flush with the inner side surface of the storage cavity 120.
The top of the guide plate 121 extends towards the top of the dishwashing liquid storage container and is provided with a partition guide plate 123; the top end of the partition guide 123 is not connected to the top surface of the storage chamber 120 and the top surface of the upper guide plate 121; the upper end of the partition guide plate 123 is provided with a through-partition notch 124. The guide plate 121 partitions the storage cavity 120 into an upper multi-layer cavity and a lower multi-layer cavity in a vertical direction, so that when the storage cavity 120 is inclined along with the cabinet door of the dish washer, the dishwashing liquid in the storage cavity 120 gradually flows to a position closer to the liquid outlet 130 and is stored; the partition guide plate 123 divides each layer of the accommodating cavity into a plurality of small partitions, and particularly as shown in fig. 3 or fig. 4, 7 partitions are divided, so that when the storage cavity 120 is tilted along with the cabinet door of the dishwasher, the dishwashing liquid in each layer of the accommodating cavity flows and is stored in the liquid outlet 130 in a partition-by-partition lateral direction; therefore, after the baffle 121 and the partition guide 123 are disposed, the combination of the baffle 121 and the partition guide 123 can gradually move the dishwashing liquid in the storage cavity 120 from the bottom of the storage cavity 120 to the liquid outlet 130 along the vertical direction and the transverse direction, so that the dishwashing liquid in the storage cavity 120 can completely flow out of the liquid outlet 130 until being used.
The lower end of the partition guide plate 123 is connected to the middle section of the guide plate 121, and the upper end thereof is inclined toward the storage cavity 120 away from the liquid passing notch 122. The partition guide plate 123 is inclined towards the liquid outlet direction along the direction of the liquid outlet 130, so that the speed of the liquid from the bottom to the top of the storage cavity 120 is further increased, the smooth throwing of the liquid is ensured, and the waste of the liquid is avoided.
A liquid passing guide plate 125 is arranged on one side of the liquid passing notch 122, which is close to the guide plate 121, and extends towards the top of the dish washing liquid storage container; the top end of the liquid passing guide plate 125 is not connected with the top surface of the storage cavity 120 and the top surface of the upper guide plate 121; the upper end of the liquid passing guide plate 125 is provided with a passing area notch 124. The liquid passing guide plate 125 performs supplementary partition on the end part of each layer of the containing cavity, and the position of the supplementary partition is changed to enable the dish washing liquid which just enters the layer of the containing cavity to be stored in the layer of the containing cavity as much as possible, so that the dish washing liquid cannot flow back to the lower layer of the containing cavity; on the other hand, the liquid passing guide plate 125 and the opposite side surfaces of the storage cavity 120 extend the liquid passing channel of the liquid passing notch 122 to the bottom surface of the upper guide plate 121, so that the dishwashing liquid can reach the upper guide plate 121 faster and flow transversely, and the speed of the dishwashing liquid flowing from the bottom of the storage cavity 120 to the position near the liquid outlet 130 is improved.
The liquid passing guide plate 125 is arranged in parallel with the inner side surface of the storage cavity 120 at the adjacent position; the lower end of the liquid passing guide plate 125 passes through the liquid passing notch 122 and is provided with a flow limiting part 126; the flow restrictor 126 is located in a downstream region of the through-region notch 124 provided in a lower vicinity thereof. When the dish washing liquid storage container is vertical, part of the dish washing liquid in the upper layer containing cavity can flow back to the lower layer containing cavity from the liquid passing notch part 122, the limiting part can guide the reflowed dish washing liquid to the partition position right below the liquid passing notch part 122, the dish washing liquid can not adhere to the back surface of the guide plate 121 and flow back to the farther partition position, and when the dish washing liquid storage container is tilted again, the dish washing liquid can rapidly enter the upper layer containing cavity from the partition position right below the liquid passing notch part 122, so that the speed of the dish washing liquid flowing from the bottom of the storage cavity 120 to the position near the liquid outlet 130 is further improved.
The left side surface and the right side surface of the dish washing liquid storage container are parallel, and the included angle range between the lower end of the guide plate 121 and the left side surface or the right side surface of the storage cavity 120 is: 95-135 degrees; the included angle between the lower end of the partition guide plate 123 and the guide plate 121 is in the range of: 95-150 degrees. The baffle 121 and the partition guide plate 123 are disposed in a limited space in the storage cavity 120, and the angle of the inclined arrangement affects the reasonable use of the limited space, and affects the flow guiding effect on the dishwashing liquid, so as to limit the included angle P between the baffle 121 and the left side or right side of the storage cavity 120 to be within 95-135 degrees, and limit the included angle M between the partition guide plate 123 and the baffle 121 to be within 95-150 degrees, thereby not only ensuring the reasonable arrangement of the baffle 121 and the partition guide plate 123 in the storage cavity 120, but also ensuring the flow guiding effect on the dishwashing liquid, as shown in fig. 3.
As shown in fig. 1 and 2 and fig. 7, a runner-based dishwashing liquid delivery system, comprising a delivery device 200 and a dishwashing liquid storage container; the feeding device 200 is provided with a liquid flow channel 32, a liquid outlet cavity 31, a feeding cavity 21, a feeding window part 22 and a quantitative valve 23, the feeding cavity 21 is provided with a feeding port 26, and the quantitative valve is arranged at the feeding port 26; the feeding cavity 21 is communicated with the feeding window part 22 through the feeding opening 26, the lower end of the liquid flow channel 32 is communicated with the liquid outlet cavity 31, and the upper end of the liquid flow channel 32 is communicated with the feeding cavity 21; the liquid outlet chamber 31 communicates with the liquid outlet 130 of the dishwashing liquid storage container. The quantitative valve 23 may be a liquid flow electromagnetic valve in the prior art, and may control the opening or closing of the liquid flow channel thereof in real time according to a control signal, so as to accurately realize the dispensing amount of the dish washing liquid flowing through the dish washing liquid. The dish washing liquid throwing system adopts a scheme that the throwing cavity 21 and the quantitative valve 23 are matched, so that the dish washing liquid throwing system enters the throwing cavity 21 by means of the operation of turning a dish washing liquid cabinet door by a user and then enters the throwing window part 22 through the quantitative valve 23 under the action of gravity; when the dish washing liquid is needed when the dishes are washed, the liquid in the dish washing cavity is used for flushing the throwing window part 22, and the dish washing liquid is thrown into the dish washing process, so that the dish washing machine can automatically and quantitatively throw the dish washing liquid, and the operation of adding washing consumables in the dish washing process each time is not needed for a user. The liquid channel is adopted by the dishwashing liquid delivery system to communicate the liquid outlet cavity with the delivery cavity, the upper end of the liquid channel is connected to the top of the delivery cavity, so that the dishwashing liquid in the liquid outlet cavity is higher than the dishwashing liquid in the delivery cavity in height after the dishwashing liquid delivery system is overturned along with a cabinet door, and the dishwashing liquid can smoothly and more flow into the delivery cavity under the action of gravity and larger liquid level difference.
More preferably, as shown in fig. 1 and 2, the dishwashing liquid is not directly put into the putting cavity 21 from the dishwashing liquid storage container, but enters the liquid outlet cavity 31 first and then flows into the putting cavity 21 through the liquid channel 32, that is, the dishwashing liquid storage container and the putting cavity 21 are separated by a special structure; because the liquid flow channel 32 has a relatively small liquid flow width, after the dishwashing liquid flows into the delivery cavity 21 from the liquid outlet cavity 31, the dishwashing liquid is difficult to flow back into the liquid outlet cavity 31 from the delivery cavity 21, and is less likely to flow back into the dishwashing liquid storage container.
