Detailed Description

The invention is further described below with reference to the accompanying drawings. For convenience of description, hereinafter, the terms "inner", "inside" or "inwardly" and the like are used with respect to descriptions near or toward the interior of the material dispenser (e.g., dishwashing block dispenser), and the terms "outer", "outside" or "outwardly" and the like are used with respect to descriptions near or toward the exterior of the material dispenser. "upper", "lower", "vertical", "horizontal" are relative to the orientation of the material dispenser arrangement in the operative state.

The spout sealing structure according to the present invention may be applied to various devices, apparatuses or equipment where the spout needs to be sealed, and the material dispenser according to the present invention may be any suitable material dispenser suitable for various fields, in particular for dispensing solid material blocks. Hereinafter, the spout sealing structure and the material dispenser according to the present invention will be described in terms of a typical dishwashing block dispenser.

Referring to fig. 1, a dish block dispenser, which is a material dispenser capable of dispensing dish blocks into a dish washer in a vertical direction, is mounted on a door body of the dish washer. In particular, the dishwashing machine may be provided with a dishwashing block dispenser when the door is open, and the dishwashing machine may be provided with a dishwashing block dispenser when the door is closed, i.e. the dishwashing block dispenser is arranged in a substantially vertical direction in the operating state.

Referring to fig. 2-8, schematic diagrams of a dishwashing block dispenser are shown as a material dispenser according to the present invention. The spout sealing structure according to the present invention is applied to the dishwashing-block dispenser. Specifically, as shown in fig. 2-4 and 6, the discharge port sealing structure mainly comprises: a discharge port 1 and a sealing cover assembly 2.

The discharge opening 1 is arranged in a plane P perpendicular to the vertical direction (in relation to the operational state of the dish bar dispenser, i.e. in the closed state of the door of the dishwasher) so that the dish bar can be discharged downwards (i.e. the material can be discharged downwards). The spout 1 comprises an outer sealing wall 10 circumferentially surrounding the spout 1, which outer sealing wall 10 extends downwards relative to the plane P of the spout 1 and the inner elevation 101 of which outer sealing wall 10 is spaced apart from the peripheral edge 11 of the spout 1. The discharge opening 1 may for example be square with rounded corners as shown, but it will be appreciated that the discharge opening may also be rectangular or other polygonal with rounded corners, depending on different design requirements etc.

The sealing cover assembly 2 is arranged to be pivotable about a pivot axis 20 parallel to the plane P of the discharge opening 1 for a pivotal movement between a closed position sealing the discharge opening 1 and an open position opening the discharge opening 1. The pivot axis 20 may be located, for example, outside of the outer sealing wall 10. The seal cap assembly 2 includes: a seal cap body 21, the seal cap body 21 comprising a circumferential side wall 210. In the closed position, the circumferential side wall 210 is in sealing engagement with the inner facade 101 of the outer sealing wall 10.

To further facilitate sealing, the circumferential side wall 210 of the seal cover body 21 may be formed by a material or material coating (e.g., rubber, resin, etc.) that has a certain elasticity and is suitable for sealing, so that when the circumferential side wall 210 is engaged with the inner side elevation 101, the circumferential side wall 210 may closely fit (even undergo a certain elastic deformation, interference fit, etc.) with the inner side elevation 101 to achieve a sufficient seal.

According to the invention, the dishwashing pieces are designed to be discharged in a downwardly projecting manner, which is a great advantage over prior art designs in which the dishwashing pieces are projected from a horizontally arranged discharge opening. Under the condition of horizontal throwing, the bowl washing block has viscosity and can drop slag, so that the bowl washing block is easy to scratch the edge of the discharge hole in the process of discharging from the horizontally arranged discharge hole and falling downwards in turn, the sealing structure at the discharge hole is polluted, and the problems of corrosion of a sealing element, deterioration of a sealing effect and the like are caused. In the present invention, however, both the outer seal wall 10 and the circumferential side wall 210 of the seal cap body 210 in the vicinity of the discharge port 1 are disposed in a substantially vertical direction in the closed position, thereby providing a seal structure outside the discharge port and in the vertical direction. By the sealing structure, the bowl washing block can be prevented from contacting the sealing interface between the sealing cover assembly and the outer sealing wall in the discharging process when the sealing cover assembly is opened, and the sealing effect is prevented from being damaged due to pollution of the sealing interface.

Further preferably, referring to fig. 3, the sealing cover body 21 may include a circumferential groove 211, and the circumferential groove 211 may be located inside the circumferential sidewall 210 and recessed into the sealing cover body 21. Preferably, in the closed position, the circumferential groove 211 may cover the tap hole 1. The grooves 211 collect debris falling from the dishwashing pieces above the outlet 1 so that in the closed position, the dishwashing pieces above the outlet 1 do not slide down onto the sealing interface and thus destroy the sealing effect.

Further preferably, referring to fig. 3, the peripheral edge 11 of spout 1 may include a circumferential flange 110 projecting outwardly in a direction relative to plane P in which spout 1 lies. In the closed position, the circumferential flange 110 is positioned above the circumferential groove 211 to direct the dishwashing piece debris into the circumferential groove 211. Preferably, the ends of the circumferential flange 110 may taper such that the ends of the circumferential flange 110 are above the circumferential groove 211 but do not completely block the circumferential groove 211. Because the circumferential flange 110 thus disposed is facing the circumferential groove 211, it is better to guide the falling dishwashing piece debris directly into the circumferential groove, avoiding it from falling in the direction of the sealing interface, further avoiding contamination of the sealing surface.

Further preferably, referring to fig. 3, the inner side of the circumferential flange 110 may form a spout guiding wall together with the inner side wall 12 of the spout 1. The guide wall of the discharge hole has a certain length along the vertical direction so as to standardize the position of the dish washing block and prevent the dish washing block from inclining, thereby ensuring that the dish washing block smoothly slides out in a correct posture when being put in.

Further preferably, referring to fig. 3, the spout 1 may further comprise a sloping inner wall 13. The sloping inner wall 13 extends obliquely upwards from a side peripheral edge of the spout 1, for example a side peripheral edge close to the pivot axis 20, when seen in the closed position. The slope inner wall can be more favorable for collecting the dish washing block scraps, the discharge hole is inevitably smaller than the thickness and the width of a storage part (described in detail later) of the material distributor (namely the dish washing block distributor) due to the existence of the sealing interface, the slope guiding structure is arranged at the joint of the discharge hole and the storage part, the dish washing block scraps can slide into the groove of the sealing cover body conveniently, the inner space of the storage part is ensured to be clean and clean, and the transmission or the throwing action of a related movement mechanism is not influenced due to the accumulation of scraps.

Further preferably, referring to fig. 3-4, the seal cap body 21 may include a seal ring 220 and a groove 212 on the circumferential side wall 210. The seal ring 220 may be disposed within the groove 212, and in the closed position, the seal ring 220 is in sealing engagement with the inner facade 101 of the outer sealing wall 10. The sealing ring 220 may, for example, have a number of sealing lips. The sealing ring 220 may also be fixedly connected to the circumferential sidewall 210, for example, by welding, bonding, injection molding, or the like.

Further preferably, referring to fig. 3, the inner elevation 101 of the outer sealing wall 10 may have a form that gradually expands outwardly in a vertically downward direction. This expanded form of the inner facade 101 further facilitates the entry and sealing engagement of the circumferential side wall 210 of the sealing cap body 21.

Further preferably, referring to fig. 4, the sealing cover body 21 may include a slag collecting groove 213. The slag collecting groove 23 is constituted by an inner surface 214 of the seal cover body 21 facing the discharge port 1 and the circumferential side wall 210, and in the closed position, the slag collecting groove 213 is opened toward the vertically upward direction. Further preferably, the slag collection channel can substantially completely cover the discharge port when the seal cap assembly closes the discharge port, so that the dishwashing piece debris can fall completely into the slag collection channel (and into the recess described above) without falling onto the seal interface, disrupting the sealing effect. And during each throwing, as the sealing cover assembly is pivoted downwards from the closed position to the open position, the scraps in the slag collecting groove can fall out, so that the slag collecting groove is emptied.

Further preferably, the seal cap assembly 2 may be driven by any suitable drive for pivotal movement between the open and closed positions. For example, referring to fig. 7, pivoting of the seal cover assembly may be accomplished by providing shaft apertures and shafts in the material dispenser (i.e., dishwashing block dispenser) housing and seal cover body, and a suitable drive motor may be provided at the pivot structure to drive rotation of the shaft. Alternatively, the driving force may be applied to other portions of the seal cover body to thereby effect pivoting of the seal cover assembly. A manner of driving the dishwashing block push rod in combination with the driving of the sealing cap assembly is described hereinafter.

The present invention also provides a material dispenser, in particular a dishwashing block dispenser and the material dispenser of the present invention is described hereinafter by way of example as a dishwashing block dispenser. Referring specifically to Figs. 2-8, the block dispenser is shown as including the spout seal and housing 3 as previously described. The housing 3 comprises a storage portion 30, which storage portion 30 is intended for storing dishwashing pieces, i.e. materials, and comprises said discharge opening 1, which discharge opening 1 is arranged at the underside of the storage portion 30, as shown in fig. 2, 6, 7.

Further preferably, the storage section 30 includes a drivable drive 31. The drive 31 may comprise a push rod 32 reciprocally movable in a vertical direction for pushing the dishwashing pieces in the storage portion 30 downwards. The push rod may include a pushing portion (not shown) for pushing the dishwashing block so that the dishwashing block can be forcibly pushed out by the pushing portion of the push rod even if the dishwashing block sticks to the inner wall of the housing or slightly interferes with the inner wall of the housing after being wetted. Moreover, the structure of the horizontal pushing and throwing in the prior art generally has higher requirement on the dimension specification of the dish washing block, when pushing small-sized dish washing blocks, the pushing out failure can be caused if the pushing stroke is insufficient, and the dish washing block distributor pushes the dish washing blocks to throw in the vertical direction, so the scheme of the invention solves the problem and is suitable for dish washing blocks with various dimension specifications. By combining the sealing at the side of the discharge hole and the push rod driving structure, the influence of the stroke error of the push rod on the sealing effect can be reduced, and if the conventional end face sealing (namely the sealing on the plane of the discharge hole) is adopted, the sealing effect is directly determined by the stroke of the push rod, and the sealing effect is directly and negatively influenced when the stroke of the push rod is in error. In addition, the push rod can be driven by any suitable gear rack or worm gear to realize the linear reciprocating motion of the push rod along the vertical direction, and the self-locking of the transmission mechanism and the improvement of the transmission efficiency can be realized.

Further preferably, the invention also provides an embodiment of the material distributing mechanism and the sealing assembly opening and closing mechanism in linkage. Referring to fig. 5, the push rod 32 includes a driving portion 320. The driving portion 320 may be, for example, a cylindrical protruding portion provided at the end of the push rod 32. The seal cover body 21 includes a driven boss 215, the driven boss 215 extending perpendicularly from an inner surface 214 of the seal cover body 21, and the driven boss 215 includes a guide groove 216, the guide groove 216 being formed on a surface of the driven boss 215 perpendicular to the pivot axis 20. The guide slot 216 includes at least a first segment 217 and a second segment 218, wherein the first segment 217 extends substantially parallel to the horizontal direction, i.e., substantially perpendicular to the pushing direction of the push rod 32, when viewed in the closed position, such that the sealing cover assembly is positioned accurately when sealing, i.e., is not inclined when the sealing cover assembly is swayed left and right due to manufacturing errors. The second section 218 extends from the first end 2171 of the first section 217. The first end 2171 of the first section 217 is further away from the pivot axis 20 than the second end 2172 of the first section 217. The driving part 320 is disposed in the guide groove 216 of the driven boss 215 so that the sealing cap assembly 2 can be driven by the push rod 32 reciprocally moving in the vertical direction to perform a pivotal movement between the open position and the closed position, as shown in fig. 2 and 6.

Specifically, starting from the closed position shown in the left-hand side of fig. 2 and 6, the push rod 32 is pushed downward in the vertical direction by the drive, and the drive portion 320 located in the guide groove 216 of the sealing cover body 21 pushes the sealing cover body 21 to pivot downward until the open position shown in the right-hand side of fig. 2 and 6, while the dish washing block falls from the open discharge opening 1; thereafter, as the push rod 32 is pulled upward in the vertical direction by the driver, the driving portion 320 located in the guide groove 216 of the sealing cover body 21 pulls the sealing cover body 21 to pivot upward until returning to the closed position. During this movement cycle of the push rod 32, a storage bin (not shown) in the storage section 30 for storing dishwashing pieces will also rotate therewith, so that when the sealing cap body 21 closes the discharge opening 1 again, a new dishwashing piece has been rotated over the discharge opening 1 awaiting delivery.

It is further preferred that both the first section 217 and the second section 218 extend in a substantially horizontal direction when viewed in the closed position. Alternatively, the second section 218 extends obliquely upward relative to the first section 217 when viewed in the closed position. That is, an included angle of 0 ° or more may exist between the first section 217 and the second section 218, which may be optimally determined according to the installation space of the sealing cap assembly, the stroke of the push rod, etc. For example, preferably, when the second stage 218 is inclined at an appropriate angle with respect to the first stage 217, the volume of the seal cap body 21 can be reduced, so that the related structure is more compact. The inclination angle is preferably 30 ° to 60 °, more preferably 45 °.

It will be appreciated that in the simplest case, the dishwashing pieces can be dropped directly from the outlet 1 after the sealing cover assembly 2 is opened. However, according to some other preferred embodiments of the invention, as in fig. 7 and 8, the housing 3 may also comprise a throwing portion 33, for example for guiding the throwing of the dish pieces falling from the spout 1 towards a desired direction. The throwing portion 33 is located below the storage portion 30, and the storage portion 30 communicates with the throwing portion 33 through the discharge port 1, so that the dishwashing pieces falling from the discharge port 1 are thrown through the throwing portion 33.

Further preferably, the pouring section 33 may comprise a sliding channel 330 communicating with the discharge opening 1 and extending downwards, a channel outlet 332 and a movable cover 331 covering the channel outlet 332, the channel outlet 332 being for example arranged substantially in a vertical direction, or the channel outlet 332 lying in a plane substantially parallel to the vertical direction, so that a dishwashing piece falling vertically from the discharge opening 1 will eventually be poured sideways to further facilitate the pouring into a desired position in the dishwasher. Of course, it will be appreciated that in various embodiments, the channel outlets 332 may be inclined to some extent relative to vertical.

It is further preferred that in the case of the movable cover 331, the upper edge 3310 of the movable cover 331 is pivotally connected to an upper edge (not shown) of the slide-down passage 330 by a pivot shaft so as to be pivotally movable between a vertical position closing the passage outlet 332 and an inclined position opening the passage outlet 332. By providing such a pivoting opening and closing structure of the movable cover 331, when the dish bar slides down the slide channel 330 to the channel outlet 332, the movable cover 331 will be pushed and opened by the dish bar to allow the dish bar to drop from the outlet 332 into the dishwasher. By providing the movable cover 331, water flow or foreign matter can be prevented from entering the inside of the putting portion 33.

In addition, the storage portion 30 may further include a cover 301 that can be opened and closed. The cover 301 may be mounted to the storage section 30 in a suitable manner and remain sealed in a closed condition so that after the cover 301 is opened or removed, a storage bin for storing dishwashing pieces may be exposed for adding dishwashing pieces thereto.

Exemplary embodiments of the inventive arrangements are described in detail hereinabove with reference to the preferred embodiments. It will be appreciated by those skilled in the art that various modifications and adaptations can be made to the specific embodiments described above without departing from the spirit of the disclosure, and that various combinations of the features and structures presented in the disclosure can be implemented without departing from the scope of the disclosure, which is defined by the appended claims.
