Description

Technical Field

[0001] This invention belongs to the field of dishwasher detergent dispensing devices, and more specifically, relates to an automatic dispensing device. Background Technology

[0002] Currently, dishwashers are being used more and more, but traditional dishwashers require users to manually add detergent each time they use them, which is cumbersome. The amount of detergent added also depends on the user's experience, and may be too much or too little. The operation is inconvenient, tedious, and not smart enough.

[0003] Chinese patent application number CN202221160499.9 discloses a washing consumables dispensing device and a dishwasher, which realizes automatic dispensing of washing consumables, but its structure is complex.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic dispensing device that has a simple structure and can automatically dispense dishwashing tablets in a quantitative manner.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] An automatic dispensing device includes a material hopper, a lifting device, and a material release device.

[0008] A material bucket, consisting of a body, a bottom, and a lid;

[0009] Lifting device, including a lifting rod that can be raised and lowered;

[0010] The bottom of the bucket is provided with a hole for the lifting rod of the lifting device to move up and down. The bucket cover is provided with a hole. The lifting rod can be lifted from the bottom of the bucket to the hole on the bucket cover or lifted out of the bucket cover from the hole on the bucket cover along the inner cavity of the bucket.

[0011] The material release device is located above the bucket lid. The material release device triggers the push rod to release the material that has been pushed out.

[0012] In this invention, a large quantity of material is stored in a container at once. The material is spherical dishwashing tablets. Each time a dishwashing tablet is needed, the lifting device raises its rod, lifting the spherical tablets from the container and pushing them out of the lid through a hole. Alternatively, the rod can push the tablets out of the lid without lifting them completely. Because a material release device is installed on the lid, after the tablets are lifted to the top, the device contacts them and pushes them off the rod, separating them from the rod. If a single lift of the rod is insufficient, the rod can be lifted multiple times to provide enough tablets for the desired washing needs. The amount of dishwasher tablets in the detergent dispenser is much greater than the amount needed for a single wash. Therefore, adding dishwasher tablets to the dispenser once can meet the needs of multiple washes, eliminating the need to manually add dishwasher tablets for each wash. Furthermore, the dishwasher can automatically dispense the correct amount of dishwasher tablets as needed, thus improving its automation level.

[0013] Furthermore, the bottom of the bucket is a concave cone shape with a hole in the center, and the lifting rod of the lifting device is located in the hole.

[0014] Because the container holds a relatively large number of dishwashing tablets and there is no need to add more for a period of time, in order to ensure that the lifting device can still effectively supply dishwashing tablets even when the number of tablets in the container is small, the bottom of the container is designed as a downward-concave cone with a hole in the center. The lifting device's rod is located in the hole. In this way, the spherical dishwashing tablets in the container automatically gather towards the center of the cone-shaped bottom under the action of gravity. When the lifting rod is raised, it will definitely lift the dishwashing tablets out of the container, thus ensuring that each lift of the lifting rod can effectively supply dishwashing tablets.

[0015] Furthermore, the top of the top rod has a material holding area.

[0016] To ensure the lifting rod effectively raises the dishwasher tablet, a material holding area is provided at the top of the rod. This area must be large enough to stably hold a spherical dishwasher tablet, preventing it from falling off the rod as it rises.

[0017] Furthermore, the material holding area at the top of the push rod is an arc-shaped recess.

[0018] As mentioned above, the material bucket contains spherical dishwashing blocks. In order to prevent the spherical dishwashing blocks from falling off the push rod when it is lifted, the material holding area at the top of the push rod needs to be set as an arc-shaped recess. In this way, after the spherical dishwashing blocks fall into the arc-shaped recess, the spherical dishwashing blocks will be stably located at the top of the push rod and rise with the push rod when it is lifted.

[0019] Furthermore, the lid is equipped with a material release device as a guide rib. The bottom of the guide rib is located on the outer periphery of the hole in the lid, and the other end of the guide rib extends obliquely upward to the top of the hole in the lid.

[0020] After the push rod raises the spherical dishwashing block, the obliquely positioned guide ribs press and push the spherical dishwashing block off the top of the push rod, separating it from the push rod. To prevent the guide ribs from pressing the spherical dishwashing block onto the top of the push rod and preventing it from falling, the guide ribs can be positioned close to the center line of the hole in the lid, rather than exactly on the center line. That is, the guide ribs are positioned on the side of the center line of the push rod, rather than exactly on the center line. In this way, since the spherical dishwashing block does not make contact with the guide ribs at its center line, but rather with its curved surface off the center line, the curved surface of the spherical dishwashing block, compressed by the guide ribs, generates a lateral pushing force, causing it to fall from the top of the push rod.

[0021] Furthermore, to prevent the guide rib from being too low and obstructing the push rod from rising out of the lid, the guide rib can include two interconnected arms with an obtuse angle between them. One arm serves as a vertical arm, its bottom end fixed to the outer periphery of the hole in the lid, while the free end of the other arm extends obliquely upwards to above the hole in the lid. This vertical arm creates sufficient space between the other arm of the guide rib and the lid for the spherical dishwashing block to rise out of the lid, preventing the guide rib from blocking the push rod's ascent and thus avoiding the problem of the spherical dishwashing block failing to detach from the top of the push rod.

[0022] Furthermore, an axial semi-through groove is provided on the upper circumference of the top rod. The semi-through groove cooperates with the guide rib, and the width of the semi-through groove is greater than the width of the guide rib.

[0023] To more effectively ensure that the guide rib contacts the spherical dishwashing block and pushes it off the top of the push rod, an axial semi-through groove is provided on the upper circumference of the push rod. The semi-through groove mates with the guide rib, and its width is greater than that of the guide rib. Thus, after the push rod rises and exits the lid, the guide rib can slide into the semi-through groove at the upper end of the push rod, ensuring that the guide rib does not obstruct the rise of the push rod and guarantees contact between the guide rib and the spherical dishwashing block, thus pushing it off the top of the push rod.

[0024] Furthermore, the lid is either sloping or conical.

[0025] To ensure the spherical dishwashing tablets roll to their designated positions after falling from the top of the lever, the lid needs to be either sloping or conical. This way, the tablets land on the lid and continue rolling along the sloping or conical surface to reach their intended positions, guaranteeing proper dispensing.

[0026] Furthermore, the lid can be separated from the barrel body or the lid can be opened and closed.

[0027] To facilitate the addition of dishwasher tablets to the bucket, the lid can be detached from the bucket body or hinged to the bucket body to allow it to open and close. When dishwasher tablets need to be added to the bucket, the lid is detached from the bucket body or the lid is opened. After adding the dishwasher tablets, the lid is placed on top of the bucket body or closed.

[0028] Furthermore, the free end of the guide rib must extend at least above the center of the arc-shaped notch at the top of the top rod.

[0029] The guide rib can be set on one side of the center line of the hole in the lid, or on the center line. In order to ensure that the guide rib can push the spherical dishwashing block off the top rod, the free end of the guide rib must extend at least above the center of the arc-shaped recess at the top of the top rod. In this way, the guide rib can push the spherical dishwashing block away from the center of the arc-shaped recess and thus fall off the top of the top rod.

[0030] Furthermore, the diameter of the arc-shaped recess at the top of the push rod is greater than or equal to the diameter of the spherical material.

[0031] In order to ensure that the top of the top rod can stably hold the spherical dishwashing block and remain stable during the rising process before the lid is lifted, the diameter of the arc-shaped recess at the top of the top rod is greater than or equal to the diameter of the spherical dishwashing block.

[0032] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0033] This invention discloses an automatic dispensing device, comprising a material hopper, a lifting device, and a material release device. The lifting device's push rod moves up and down along the bottom of the hopper, lifting spherical dishwasher tablets from the bottom upwards along the inner cavity of the hopper and pushing them out of the hopper lid. The material release device, located above the hopper lid, triggers the push rod to release the material, causing it to detach from the push rod. By holding a large quantity of spherical dishwasher tablets in the hopper at a time, the lifting device's push rod rises to dispense the tablets each time a dishwasher is needed. The push rod is raised multiple times to provide dishwasher tablets as required, ensuring a sufficient total quantity for each wash. Adding dishwasher tablets to the hopper once is sufficient for multiple washes, eliminating the need for manual addition of tablets for each wash. The device has a simple structure and automatically dispenses a precise amount of dishwasher tablets as needed, improving the automation level of the dishwasher.

Therefore, they should not be construed as limiting this invention.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] like Figures 1 to 3 As shown, the present invention provides an automatic dispensing device, which includes a material hopper, a lifting device, and a material release device.

[0046] The material bucket has a lid 1, a body 2, and a bottom 3. The lifting device includes a lifting rod 4 that can be raised and lowered.

[0047] The bottom of the bucket has a hole for the lifting rod of the lifting device to move up and down, and the bucket lid has a hole. The lifting rod can be lifted from the bottom of the bucket to the hole on the lid or lifted out of the lid through the hole on the lid. In this embodiment, both the bucket lid 1 and the bucket bottom 3 have holes for the lifting rod 4 of the lifting device to move up and down, and the lifting rod 4 can be lifted from the bottom 3 to the lid 1 through the hole on the bucket.

[0048] The material release device is located above the barrel cover 1. The material release device triggers the top rod 4 to release the material that has been pushed out, causing it to detach from the top rod 4.

[0049] In this invention, a large number of spherical dishwashing blocks 5 are placed in a container at a time. Each time dishwashing is needed, the lifting device raises the rod 4, lifting the spherical dishwashing blocks 5 from the container and pushing them out of the lid 1 through a hole. Since a material release device is provided on the lid 1, after the spherical dishwashing blocks 5 are lifted above the lid 1, the material release device contacts the spherical dishwashing blocks 5 and pushes them off the rod 4, thus separating them from the rod 4. If the number of dishwashing blocks provided by a single lift of the rod 4 is insufficient for the washing needs, the rod 4 can be lifted multiple times to provide more dishwashing blocks, ensuring a sufficient total quantity for the washing requirements. The amount of dishwasher tablets in the detergent dispenser is much greater than the amount needed for a single wash. Therefore, adding dishwasher tablets to the dispenser once can meet the needs of multiple washes, eliminating the need to manually add dishwasher tablets for each wash. Furthermore, the dishwasher can automatically dispense the correct amount of dishwasher tablets as needed, thus improving its automation level.

[0050] Combination Figure 1 , Figure 4 As shown, the bottom 3 of the material bucket is a concave cone shape with a hole in the center, and the lifting rod 4 of the lifting device is located in the hole.

[0051] Since the container contains a large quantity of dishwashing tablets and there is no need to add more for a period of time, in order to ensure that the lifting rod 4 of the lifting device can still effectively provide dishwashing tablets even when the quantity of dishwashing tablets in the container is small, the bottom 3 of the container is designed as a concave cone shape with a hole in the center. The lifting rod 4 is located in the hole. In this way, the spherical dishwashing tablets 5 in the container will automatically gather towards the center of the conical bottom 3 under the action of gravity. When the lifting rod 4 lifts, it will definitely lift the dishwashing tablets out of the container, thus ensuring that each lift of the lifting rod 4 can effectively provide dishwashing tablets.

[0052] In order for the top rod 4 to effectively lift the dishwashing block, a material holding area is provided at the top of the top rod 4. The material holding area must be able to stably place a spherical dishwashing block 5 so that the spherical dishwashing block 5 will not fall off the top rod 4 when it is lifted upward.

[0053] As described above, the material bucket contains spherical dishwashing blocks 5. In order to prevent the spherical dishwashing blocks 5 from falling off the top rod 4 when it is lifted upward, the material holding area at the top of the top rod 4 needs to be set as an arc-shaped recess 42. In this way, after the spherical dishwashing blocks 5 fall into the arc-shaped recess 42, the spherical dishwashing blocks 5 will be stably located at the top of the top rod 4 and rise with the top rod 4 when it is lifted.

[0054] In order to ensure that the top of the top rod 4 can stably hold the spherical dishwashing block 5 and not fall off during the rising process before the lid 1 is lifted, the diameter of the arc-shaped recess 42 at the top of the top rod 4 is greater than or equal to the diameter of the spherical dishwashing block 5.

[0055] The lid 1 is equipped with a material release device, which is a guide rib 6. The bottom of the guide rib 6 is located on the outer periphery of the hole in the lid 1, and the other end of the guide rib 6 extends obliquely upward to the top of the hole in the lid 1.

[0056] After the push rod 4 raises the spherical dishwashing block 5, the obliquely positioned guide rib 6 pushes the spherical dishwashing block 5 off the top of the push rod 4, causing it to separate from the push rod 4. To prevent the guide rib 6 from pressing the spherical dishwashing block 5 onto the top of the push rod 4 and preventing it from falling, the guide rib 6 can be positioned close to the center line of the hole in the lid 1, rather than exactly on the center line. That is, the guide rib 6 is positioned on the side of the center line of the push rod 4, rather than exactly on the center line. In this way, since the spherical dishwashing block 5 does not contact the guide rib 6 at its center line, but rather at an arc-shaped surface deviating from the center line, the arc-shaped surface of the spherical dishwashing block 5 can be pushed laterally by the guide rib 6, causing it to fall off the top of the push rod 4.

[0057] To prevent the guide rib 6 from being too low and obstructing the lifting rod 4 from exiting the lid 1, the guide rib 6 can include two interconnected arms with an obtuse angle between them. One arm serves as a vertical arm, with its bottom end fixed to the outer periphery of the hole in the lid 1. The free end of the other arm extends obliquely upward to above the hole in the lid 1. This vertical arm creates sufficient space between the other arm of the guide rib 6 and the lid 1 for the spherical dishwashing block 5 to exit the lid 1, preventing the guide rib 6 from obstructing the lifting rod 4 and causing the spherical dishwashing block 5 to not fully exit the lid 1, thus avoiding the problem of the spherical dishwashing block 5 being unable to detach from the top of the lifting rod 4.

[0058] The guide rib 6 can be set on one side of the center line of the hole in the lid 1, or it can be set on the center line. In order to ensure that the guide rib 6 can push the spherical dishwashing block 5 off the top rod 4, the free end of the guide rib 6 must extend at least above the center of the arc-shaped recess 42 at the top of the top rod 4. In this way, the guide rib 6 can push the spherical dishwashing block 5 away from the center of the arc-shaped recess 42 and thus fall off the top of the top rod 4.

[0059] The upper circumference of the top rod 4 is provided with an axial semi-through groove 41, which cooperates with the guide rib 6. The groove width of the semi-through groove 41 is greater than the width of the guide rib 6.

[0060] To more effectively ensure that the guide rib 6 contacts the spherical dishwashing block 5 and pushes it off the top of the push rod 4, an axial semi-through groove 41 is provided on the upper circumference of the push rod 4. The semi-through groove 41 cooperates with the guide rib 6, and the width of the semi-through groove 41 is greater than the width of the guide rib 6. In this way, after the push rod 4 rises and exits the lid 1, the guide rib 6 can slide into the semi-through groove 41 at the upper end of the push rod 4, so that the guide rib 6 will not block the rise of the push rod 4, and will definitely ensure that the guide rib 6 contacts the spherical dishwashing block 5 and pushes it off the top of the push rod 4.

[0061] In order for the spherical dishwashing block 5 to roll to the set position after falling from the top of the push rod 4, the lid 1 needs to be an inclined or conical surface. In this way, after the spherical dishwashing block 5 falls from the top of the push rod 4 onto the lid 1, it can continue to roll to the set position along the inclined or conical surface of the lid 1, ensuring the proper dispensing of the spherical dishwashing block 5.

[0062] To facilitate the addition of dishwasher tablets to the container, the lid 1 can be detached from the container body 2, or the lid 1 can be hinged to the container body 2 to allow it to open and close. When dishwasher tablets need to be added to the container, the lid 1 is detached from the container body 2 or the lid 1 is opened. After adding the dishwasher tablets, the lid 1 is placed on top of the container body 2 or the lid 1 is closed.

[0063] At work, such as Figure 1 As shown, the push rod 4 rises from the bottom 3 of the bucket upwards along the inner cavity of the bucket. At this time, a spherical dishwashing block 5 is located in the arc-shaped recess 42 at the top of the push rod 4 and rises with the push rod 4, as... Figure 2As shown, after the push rod 4 pushes the spherical dishwashing block 5 out of the lid 1, the guide rib 6 slides into the semi-through groove 41 at the upper end of the push rod 4. The push rod 4 continues to rise. Since the other end of the guide rib 6 extends obliquely upward to above the hole in the lid 1, the guide rib 6 contacts the spherical dishwashing block 5 at the top of the push rod 4, forcing it to deviate from the arc-shaped recess 42 at the top of the push rod 4. The degree of deviation increases with the degree of rise of the push rod 4, eventually causing the spherical dishwashing block 5 to fall from the top of the push rod 4. After landing on the lid 1, the spherical dishwashing block 5 rolls along the conical surface of the lid to the set position, thus completing the placement. The push rod of the lifting device descends, and the above action is repeated to lift the spherical dishwashing block 5.

[0064] This invention discloses an automatic dispensing device, comprising a material hopper, a lifting device, and a material release device. The lifting device's push rod moves up and down along the openings in the hopper bottom and lid, lifting spherical dishwasher tablets from the bottom of the hopper upwards through the inner cavity and releasing them from the lid. The material release device, located above the lid, activates the push rod, releasing the propelled material. By storing a large quantity of spherical dishwasher tablets in the hopper at a time, the lifting device's push rod rises to dispense the tablets each time a dishwasher is needed. The push rod is raised multiple times to provide the required amount of tablets, ensuring a sufficient total quantity for each wash. Adding dishwasher tablets to the hopper once is sufficient for multiple washes, eliminating the need for manual addition each time. The device is simple in structure and automatically dispenses a precise amount of tablets as needed, improving the automation level of the dishwasher.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
