Referring to fig. 1 and 2, in a transportation component 11 according to an embodiment of the present invention, the transportation component 11 includes a telescopic assembly 110 and a transportation pipe 118 connected to the telescopic assembly 110, and the telescopic assembly 110 is formed with an accommodating space 120. The conveying member 11 is used for driving the telescopic assembly 110 to extend by the first fluid under the condition that the accommodating space 120 is filled with the first fluid. The delivery tube 118 is formed with a fluid passage 119 spaced from the receiving space 120, the fluid passage 119 being for delivering a second fluid.

In the above-mentioned conveying component 11, the telescopic assembly 110 is provided to reduce the space occupied by the household appliance 20, and the space required by the telescopic assembly 110 in the process of telescopic is also small. The delivery pipe 118 can cooperate with the functional requirements of the household appliance 20 to realize the action of the second fluid, and no manual operation is needed, so that the household appliance 20 (as shown in fig. 10) is more intelligent, the working efficiency is improved, and the service time is shortened.

Specifically, in one example, the second fluid is acted upon, such as by providing water, air, water, or air intake. It should be noted that the action of the second fluid is not limited to the above example, and may be specifically configured according to the requirement.

In the illustrated embodiment, the retraction assembly 110 is retractable in an up-down direction. The telescopic assembly 110 is formed with a receiving space 120. The receiving space 120 is sealed to prevent leakage of the first fluid. In some embodiments, the first fluid may be a gas, and the bellows assembly 110 may be extended using gas pressure. In some embodiments, the first fluid may be a liquid and hydraulic pressure may be used to extend retraction assembly 110.

In addition, a delivery tube 118 is coupled to retraction assembly 110. The telescopic assembly 110 can move the delivery pipe 118 during the telescopic process. Thus, the delivery pipe 118 can deliver the second fluid in cooperation with the telescopic state of the telescopic assembly 110, and no additional component for driving the delivery pipe 118 is required. The structure of the conveying member 11 can be simplified. In some embodiments, delivery tube 118 may be disposed within retraction assembly 110 and communicate to the exterior of retraction assembly 110. In some embodiments, delivery tube 118 is partially disposed within retraction assembly 110 and partially disposed outside of retraction assembly 110 and is coupled to the exterior of retraction assembly 110. In some embodiments, delivery tube 118 may be located outside of retraction assembly 110.

Further, the delivery pipe 118 is formed with a fluid passage 119 therein spaced from the receiving space 120. In this manner, the second fluid may be delivered to a particular location or region of the exterior via the fluid channel 119.

In some embodiments, the conveying component 11 is further configured to maintain the retraction assembly 110 in an extended state with the first fluid in the receiving space 120. In this way, the first fluid can be used to maintain the extended state of the telescopic assembly 110 without additional components, thereby enabling specific control in coordination with the function of the household appliance 20.

Specifically, when a certain amount of the first fluid is introduced into the receiving space 120, a fluid pressure (e.g., a gas pressure or a liquid pressure) may be generated in the receiving space 120 by continuously introducing the first fluid into the receiving space 120, so as to drive the expansion assembly 110 to expand and maintain the expanded state. In this way, it is possible to match the functional requirements of introducing the second fluid into the interior of the household appliance 20 or of extracting the second fluid through the delivery duct 118.

In one example, the household appliance 20 is an electric rice cooker, and when the telescopic assembly 110 is in the extended state, the telescopic assembly 110 can be extended below the liquid level in the electric rice cooker, and air can be injected into water through the delivery pipe 118 (in this case, the second fluid is air) to perform bubble washing of rice.

In some embodiments, the transport component 11 is used to retract the retraction assembly 110 upon withdrawal of the first fluid from the housing space 120. In this way, it is ensured that the transport component 11 does not take up a large space.

Specifically, under the condition that a certain amount of first fluid is introduced into the accommodating space 120, the first fluid in the accommodating space 120 is extracted, so that negative pressure is present in the accommodating space 120, the telescopic assembly 110 is driven to retract inwards, and gradually returns to the state before the first fluid is introduced, and the telescopic assembly 110 occupies a smaller space in the retracted state.

In some embodiments, referring to fig. 1, the telescoping assembly 110 is formed with a first port 111 and a second port 112. The delivery tube 118 extends through the first port 111 and is partially disposed in the receiving space 120. The delivery tube 118 communicates with the second port 112, the delivery tube 118 for outputting the second fluid entering the fluid passage 119 from the second port 112, and/or the delivery tube 118 for outputting the second fluid entering the fluid passage 119 from the second port 112. In this manner, the installation of the delivery tube 118 and the unidirectional and/or bidirectional delivery of the second fluid using the delivery tube 118 is achieved.

Specifically, the delivery pipe 118 extends from the first port 111 of the telescopic assembly 110 into the receiving space 120, and communicates with the second port 112 within the receiving space 120. In the expansion direction, the first port 111 and the second port 112 are respectively disposed at both end portions of the expansion assembly 110.

In the illustrated embodiment, the first port 111 is provided at a top portion 113 of the retraction assembly 110 and the second port 112 is provided at a bottom portion 116 of the retraction assembly 110. The other end of the delivery tube 118, which is located outside of the retraction assembly 110, may be connected to a fluid source, such as a gas or liquid source.

In the case where the delivery tube 118 is used to output the second fluid entering the fluid channel 119 through the second port 112, the second fluid may be delivered along the delivery tube 118 to the second port 112 and out of the retraction assembly 110 into the interior of the household appliance 20 from the second port 112. The second fluid may be a gas and/or a liquid. Thus, the functions of liquid inlet and air inlet are realized.

In case the delivery tube 118 is used for outputting the second fluid entering the fluid channel 119 from the second port 112, the second fluid may be output from inside the household appliance 20 along the delivery tube 118. The second fluid may be a gas and/or a liquid. Thus, the functions of liquid pumping and air pumping are realized.

In summary, the delivery pipe 118 is used to output the second fluid entering the fluid channel 119 through the second port 112, and/or the delivery pipe 118 is used to output the second fluid entering the fluid channel 119 from the second port 112, that is, the delivery pipe 118 can achieve the two-way flow delivery of the second fluid, or achieve one of the two-way delivery. May be configured according to the functional requirements of the household appliance 20. And is not particularly limited herein.

In addition, in the embodiment shown in fig. 1, a sealing member may be disposed between the delivery pipe 118 and the first port 111, so that a good sealing property in the receiving space 120 may be ensured, thereby preventing leakage of the first fluid.

In some embodiments, referring to fig. 2, the telescoping assembly 110 is formed with a first port 111 and a second port 112. The delivery pipe 118 is positioned in the receiving space 120 and communicates the first port 111 and the second port 112. The delivery tube 118 is used to allow the second fluid entering the fluid passage 119 from the first port 111 to be output from the second port 112, and/or the delivery tube 118 is used to allow the second fluid entering the fluid passage 119 from the second port 112 to be output from the first port 111. In this manner, unidirectional and/or bidirectional delivery of the second fluid by the delivery tube 118 may also be achieved.

Specifically, in the case where the delivery pipe 118 is used to cause the second fluid, which enters the fluid passage 119 from the first port 111, to be output from the second port 112, the second fluid may be delivered to the second port 112 through the first port 111. The second fluid may be a gas and/or a liquid. Thus, the functions of liquid inlet and air inlet are realized.

In the case where the delivery pipe 118 is used to cause the second fluid, which enters the fluid passage 119 from the second port 112, to be output from the first port 111, the second fluid may be delivered to the first port 111 along the delivery pipe 118. The second fluid may be a gas and/or a liquid. Thus, the functions of liquid pumping and air pumping are realized.

In some embodiments, retraction assembly 110 has a top portion 113 and a bottom portion 116 in the direction of retraction. The first port 111 is provided at the top 113 and the second port 112 is provided at the bottom 116. In this manner, the placement of the delivery tube 118 within the receiving space 120 is facilitated.

Specifically, in the illustrated embodiment, the delivery tube 118 is helical and is positioned within the receiving space 120. Thus, in the case where the delivery tube 118 moves as the telescopic assembly 110 is extended and retracted, the helical delivery tube 118 facilitates the movement of the delivery tube 118. Specifically, the delivery tube 118 may be telescoped in an up-and-down direction in cooperation with the telescoping assembly 110.

Accordingly, via the second port 112, the second fluid may flow along the fluid passage 119 to the first port 111, performing a function of pumping the second fluid. Meanwhile, the telescopic assembly 110 drives the conveying pipe 118 to extend and retract in the up-and-down direction, so that the conveying part 11 can occupy a small space. In one example, the first port 111 and the second port 112 may be disposed at the top portion 113 and the bottom portion 116, respectively, along a central axis direction of the retraction assembly 110. Thus, the processing is convenient.

It should be noted that the following embodiments are described and explained with reference to the embodiment of the telescopic assembly 110 shown in fig. 2. It is to be understood that the description and explanation given in connection with the embodiment shown in fig. 2 also applies substantially to the telescopic assembly 110 of the embodiment shown in fig. 1.

Further, referring to fig. 2 and 3, in some embodiments, the telescopic assembly 110 includes a plurality of telescopic members 12, each of the telescopic members 12 has a hollow structure, the telescopic members 12 are sequentially sleeved along a telescopic direction, and the innermost telescopic member 12 forms a bottom 116. Thus, the arrangement of the telescopic structure of the telescopic assembly 110 and the accommodating space 120 is realized, and the structure is simple.

Specifically, each telescopic member 12 may be a hollow cylindrical structure, and the inner spaces of each telescopic member 12 are connected to each other to form the receiving space 120. Referring to fig. 2, a top portion 113 is formed on the top telescopic member 12, and the other telescopic members 12 are sequentially sleeved on the telescopic member 12 located on the top portion 113. In the up-down direction, the extensible member 12 having the smallest cross-sectional area is located innermost, and one end portion thereof is sealed to form the bottom 116. Adjacent two telescoping members 12 are slidable relative to each other.

In some embodiments, the telescoping assembly 110 includes a first end member 114 connected to the outermost telescoping member 12 and positioned at the top portion 113, the first end member 114 defining a first port 111 and a third port 115, the third port 115 communicating with the receiving space 120 and adapted for passage of the first fluid. In this manner, the process handling and replacement of the first end member 114 may be facilitated.

It is understood that a first fluid may be introduced into housing space 120 to drive retraction assembly 110 to extend. Specifically, the first fluid passes into the housing space 120 along the third port 115, and fluid pressure is generated in the housing space 120. Fluid pressure may urge retraction assembly 110 to extend downward. In this manner, extension of retraction assembly 110 is achieved.

In the illustrated embodiment, the first port 111 and the third port 115 are not in communication with each other within the first end member 114 to avoid interaction between the first fluid and the second fluid.

In addition, since the first end member 114 can be separately machined with the first port 111 and the third port 115, the first end member 114 can be detachably mounted to the outermost one of the expanders 12. In one example, a sealing element may be disposed between the first end member 114 and the outermost telescoping member 12 to ensure the sealing of the receiving space 120.

In some embodiments, retraction assembly 110 further includes a second end member 117, second end member 117 being disposed at base 116, second end member 117 covering second port 112. In this manner, material is prevented from blocking the second port 112.

Specifically, in the illustrated embodiment, the second port 112 opens downwardly. During the process of extending the telescopic assembly 110 downward into the interior of the household appliance 20, the second port 112 with the downward opening is easily blocked by the material (such as rice) inside the household appliance 20. Thus, the second end member 117 covers the second port 112 and acts to prevent material from blocking the second port 112.

The connection between the bottom 116 and the second end member 117 can be achieved by means of threads, snap-fit, welding, interference, etc., and the connection is not limited in detail.

In some embodiments, the second end member 117 has a protrusion 1171, the protrusion 1171 connecting the outer side of the innermost telescoping member 12, the protrusion 1171 for limiting the telescoping position of the innermost telescoping member 12. Thus, the telescopic effect of the conveying component 11 is ensured, and meanwhile, the structure is simple.

Specifically, referring to fig. 2, the protrusion 1171 corresponds to another telescopic member 12 sleeved on the innermost telescopic member 12. As shown in fig. 2, the innermost telescopic member 12 is a telescopic member 12d, the other telescopic member 12 sleeved on the telescopic member 12d is a telescopic member 12c, and the protrusion 1171 protrudes out of the outer side surface of the telescopic member 12 d.

The protrusion 1171 may limit the retracted position of the telescoping member 12d during retraction of the telescoping assembly 110. For example, during retraction of retraction assembly 110, with boss 1171 abutting the bottom of telescoping member 12c, the retraction travel of telescoping member 12d is limited by boss 1171.

In some embodiments, a gap 1172 is formed between the second end member 117 and the base 116 in communication with the second port 112. In this manner, the delivery of the second fluid at the bottom 116 may be facilitated.

Referring back to fig. 2, by providing the gap 1172, the fluid output from the second port 112 is more easily introduced into the interior of the household appliance 20, and the fluid from the interior of the household appliance 20 is more easily introduced into the second port 112. In particular, in the case where the second fluid in the fluid channel 119 is output by the second port 112, laterally of the second end element 117, the second fluid can be more easily conveyed inside the household appliance 20 at the bottom 116; in the event that the second fluid is delivered from the second port 112 to the fluid passage 119, the second fluid inside the household appliance 20 may more easily enter the second port 112 along the gap 1172.

In certain embodiments, second end member 117 is formed with a filter aperture 1173 in communication with gap 1172. In this manner, the filter aperture 1173 prevents a relatively large volume of material in the second fluid from entering the gap 1172 and blocking the second port 112 if the second fluid is delivered at the gap 1172.

In the illustrated embodiment, a filter aperture 1173 is provided between the gap 1172 and the external environment. A second fluid is required to enter gap 1172 along filter aperture 1173. In particular, when the household appliance 20 is an electric rice cooker, the second fluid may be water. When the conveying component 11 is used for extracting water in the electric cooker, the filtering holes 1173 can prevent rice grains in the electric cooker from entering the gap 1172, so that the second port 112 can be prevented from being blocked by the rice grains, and the conveying efficiency of the conveying component 11 can be prevented from being influenced. Preferably, the size of the filter holes 1173 can be smaller than the smallest cross-section of the rice kernels.

In one example, the plurality of telescoping members 12 are each circular in cross-section perpendicular to the telescoping direction, making the telescoping members 12 easy to machine. In other embodiments, the cross section of the plurality of telescoping members 12 perpendicular to the telescoping direction may be rectangular, triangular, and other regular or irregular polygons, etc.

In the present embodiment, the delivery pipe 118 is telescopically disposed in the receiving space 120, and particularly, the length of the delivery pipe 118 is greater than the linear distance between the first port 111 and the second port 112 in a case where the telescopic assembly 110 is at a maximum extension length.

In the illustrated embodiment, the delivery tube 118 may be helical. In this manner, the delivery tube 118 can be stacked and has a minimum stretchable length corresponding to the telescopic assembly 110, facilitating the installation and detachment of the delivery tube 118, and preventing the delivery tube 118 from being separated from the first port 111 and/or the second port 112 or being broken so that the fluid passage 119 cannot communicate in case the delivery tube 118 is stretched in the up-down direction.

In some embodiments, the plurality of telescoping members 12 includes a first telescoping member 121 and a second telescoping member 124, the second telescoping member 124 being slidably disposed within the first telescoping member 121. A sealing member 13 is disposed between the first telescopic member 121 and the second telescopic member 124, and the sealing member 13 seals a gap between the first telescopic member 121 and the second telescopic member 124. Thus, the telescopic assembly 110 can be prevented from being unable to extend or retract due to fluid leakage in the housing space 120 while achieving the telescopic effect of the telescopic assembly 110.

Referring to fig. 4-6, specifically, the cross-sectional area of the first expansion element 121 along the vertical direction is larger than the cross-sectional area of the second expansion element 124, and the second expansion element 124 and the first expansion element 121 can slide relatively along the vertical direction. This allows the second telescoping member 124 to be received within the hollow structure of the first telescoping member 121. The sealing member 13 is provided to ensure that the sealing property of the receiving space 120 is maintained even when the first telescopic member 121 and the second telescopic member 124 are stationary and relatively moved.

In certain embodiments, the seal 13 may include a mounting portion 131 and a resilient seal arm 134 extending from the mounting portion 131. Referring to fig. 5 and 7, the mounting portion 131 is mounted on an outer sidewall of the second expansion element 124, the elastic sealing arm 134 elastically abuts against an inner sidewall surface of the first expansion element 121, and a moving space for the elastic sealing arm 134 to elastically deform is formed on a side of the mounting portion 131 where the elastic sealing arm 134 protrudes. In this way, the sealing effect is achieved while the sealing element 13 is prevented from being displaced on the outer side wall of the second telescopic element 124.

It will be appreciated that when the resilient sealing arm 134 resiliently abuts against the inner side wall of the first telescopic member 121, the resilient sealing arm 134 is resiliently deformed and is squeezed into the active space. Since the movable space is sufficient to accommodate the elastic sealing arm 134, the elastic sealing arm 134 cannot be attached to the surface of the mounting portion 131 in the movable space, so that the elastic sealing arm 134 only exerts the elastic force generated by the elastic deformation of itself on the inner sidewall of the first telescopic member 121, and an excessive friction force is not generated. In this way, the sealing member 13 is not displaced on the inner side wall of the first telescopic member 121, and the sealing performance of the accommodating space 120 may be affected.

In some embodiments, the outer sidewall of the second telescopic member 124 is formed with a groove 129, and the mounting portion 131 is mounted in the groove 129. In this manner, groove 129 may serve to confine seal member 13 to second telescoping member 124, preventing seal member 13 from shifting.

Referring to fig. 4, the outer sidewall of the second telescopic member 124 may have two side plates along the vertical direction. A groove 129 may be formed between the two side plates. The mounting portion 131 is secured within the recess 129. It will be appreciated that in the event of mutual sliding between the first telescopic member 121 and the second telescopic member 124, the sealing member 13 is subjected to a sliding friction force due to the fact that the sealing member 13 is fitted to the surface of the first telescopic member 121. By providing the groove 129 on the outer side wall of the second telescopic member 124, the sealing member 13 is prevented from being displaced, which may affect the sealing performance of the receiving space 120.

In some embodiments, referring to fig. 5, the resilient seal arm 134 includes a first arm 135 and a second arm 136. The first arm 135 extends obliquely upward from the mounting portion 131 in the telescopic direction. The second arm 136 is connected to an end of the first arm 135 remote from the mounting portion 131. In this way, the second telescopic member 124 can be easily slid along the inner sidewall of the first telescopic member 121 while preventing the sealing member 13 from being displaced.

In the illustrated embodiment, the mounting portion 131 extends in the vertical direction and is formed with a top end 132 and a bottom end 133. Referring to fig. 4, the top end 132 and the bottom end 133 respectively contact two ends of the inner wall of the groove 129 with interference, the first arm 135 extends upward from the bottom end 133 of the mounting portion 131 along the direction B and is connected to the second arm 136, the second arm 136 extends upward from the first arm 135 along the direction C, and an included angle is formed between the extending portion of the first arm 135 along the direction B and the mounting portion 131. In this way, a movable space for accommodating the elastic sealing arm 134 is formed between the elastic sealing arm 134 and the mounting portion 131 at an interval, so that a force generated between the sealing member 13 and the inner sidewall of the first expansion member 121 is substantially an elastic force, thereby preventing the sealing member 13 from being displaced. In one example, the C direction is parallel to the telescoping direction.

Specifically, the included angle is an acute angle. Referring to fig. 5, when the first expansion member 121 is sleeved on the second expansion member 124, the elastic sealing arm 134 can have a guiding function, so as to facilitate the sliding of the second expansion member 124 along the inner sidewall of the first expansion member 121.

In some embodiments, referring to fig. 4, the first telescopic member 121 includes a first cylinder 122 and a first stopping edge 123 extending from the first cylinder 122 into the first cylinder 122. Second telescoping member 124 includes a second barrel 125 and a second stop 126 extending from second barrel 125 and beyond second barrel 125. The second stop rib 126 cooperates with the first stop rib 123 to limit the extension distance of the first telescopic member 121 and the second telescopic member 124. Thus, the first and second

telescopic members

121 and 124 are prevented from being separated.

Specifically, the first stopping edge 123 extends radially on the inner side wall of the bottom of the first cylinder 122 and is formed with a through hole for the second cylinder 125 to pass through. Second stop 126 includes a first stop 127 and a second stop 128, first stop 127 extending radially on the outside wall of the top of second barrel 125. Correspondingly, second rib 128 extends radially on the outside wall of the bottom of second cylinder 125. The thickness of the first stopping edge 123 may be greater than that of the first stopping edge 127, when the second cylinder 125 penetrates through the first cylinder 122, the first stopping edge 123 may limit the sliding direction of the second cylinder 125 on the inner side wall of the first cylinder 122, and the first stopping edge 127 and the first stopping edge 123 may cooperate to limit the downward telescopic distance of the second cylinder 125.

Similarly, second flange 128 and first stop flange 123 cooperate to limit the upward extension and retraction of second barrel 125. As such, first stop edge 123 and second stop edge 126 cooperatively define second telescoping member 124 for sliding movement within first barrel 122. In one example, the position of first rib 127 and second rib 128 on second barrel 125 can be freely adjusted. The specific values of the positions of the first rib 127 and the second rib 128 are not limited herein.

Additionally, in other embodiments, the second stop 126 may define a groove 129. The groove 129 is formed in the second cylinder 125 in an annular shape, and two corresponding annular side plates are formed in the vertical direction, the first rib 127 forms one side plate of the groove 129, the other side plate of the groove 129 is located above the second rib 126 in the vertical direction, and the top end 132 and the bottom end 133 are respectively abutted to the two side plates of the groove 129 in an interference manner. Thus, the second stopping edge 126 is provided to eliminate the need for a side plate for the groove 129, and to simplify the structure.

In addition, first rib 127 and/or second rib 128 can be removably coupled to second cylinder 125, in one example, first rib 127 is removably coupled to second cylinder 125, and preferably, second rib 128 is removably coupled to second cylinder 125. In this way, the second telescopic member 124 is conveniently slid into the top of the first cylinder 122 along the inner side wall of the first cylinder 122.

In some embodiments, the conveying member 11 includes a restoring member 137 coupled to the plurality of telescoping members 12, the restoring member 137 for driving the telescoping assembly 110 to retract. In this manner, a retraction effect of retraction assembly 110 may be achieved.

Specifically, referring to fig. 4, an accommodating space 138 is movably defined among the first retaining edge 127, the first cylinder 122, the second cylinder 125, and the first retaining edge 123. The restoring member 137 is disposed in the accommodating space 138. One end of the reset piece 137 abuts against the bottom of the first stopping edge 127, and the other end of the reset piece 137 abuts against the top of the first stopping edge 123.

In particular, the first fluid may be a gas. When air is introduced into the receiving space 120 through the third opening 115, the second expansion member 124 is pushed by air pressure to slide downward along the inner sidewall of the first expansion member 121. Meanwhile, the restoring member 137 is pressed in the accommodating space 138 to be elastically deformed, so that the restoring member 137 has a tendency of sliding and retracting the second extensible member 124 into the first extensible member 121.

In the case where the gas is output from the housing space 120 along the third port 115, the restoring member 137 is restored and pushes the first rib 127 in the retracting direction. Second telescoping member 124 is ultimately slidably retracted within first telescoping member 121. In this manner, the retraction effect of retraction assembly 110 is achieved. When the first fluid is liquid, the action principle is similar to that when the first fluid is gas, and will not be described herein.

In one example, the upper surface of the first stopper 123 is provided with a flange for defining the restoring member 137, and the flange has the effect of thickening the first stopper 123. Thus, the first stopper edge 123 may have a certain strength. The restoring member 137 prevents the first stopping edge 123 from separating from the first cylinder 122 or the first stopping edge 123 from breaking when the elastic force applied to the first stopping edge 123 is too large.

Additionally, in one example, the restoring member 137 may resiliently couple the top portion 113 and the first telescoping member 121, and/or the restoring member 137 may resiliently couple the top portion 113 and the second telescoping member 124. In another example, restoring member 137 is disposed externally to the overall structure of retraction assembly 110.

In addition, the restoring member 137 may also include a hydraulic member, a pneumatic member (e.g., a cylinder), a motor, and a magnetic member, and the driving principle is similar to that of the elastic member, and thus, will not be described in detail. In the case that the restoring member 137 includes a magnetic member, the magnetic member may include a permanent magnetic member, and may also include an electromagnetic member, and the second telescopic member 124 slides in the telescopic direction within the first telescopic member 121 by the acting force (including the attractive force or the repulsive force) of the two magnetic members.

In one example, the first stopping edge 123 is provided with a permanent magnetic member, and the second stopping edge 126 is provided with an electromagnetic member, so that the sliding of the second telescopic member 124 is realized by changing the magnetism of the electromagnetic member so that the first stopping edge 123 and the second stopping edge 126 attract or repel each other. In another example, the first stop edge 123 and the second stop edge 126 are each provided with an electromagnetic member. The restoring member 137 may also include a combination of two or more of an elastic member, a hydraulic member, a pneumatic member, a motor, and a magnetic member, and the other embodiments are not particularly limited herein.

It is understood that in this embodiment, the first telescopic member 121 and the second telescopic member 124 do not only refer to two specific telescopic members 12 sleeved with each other in the telescopic assembly 110, but only for clearly describing the specific related structure for realizing the telescopic function between two adjacent telescopic members 12, any two telescopic members 12 sleeved and connected have the same or similar specific structure between the first telescopic member 121 and the second telescopic member 124.

In particular, in the illustrated embodiment, the number of telescopic elements 12 is four, namely

telescopic elements

12a, 12b, 12c, 12d, in the first case the first telescopic element 121 can be 12a and the second telescopic element 124 can be 12 b; in the second case, the first telescopic member 121 may be 12b, and the second telescopic member 124 may be 12 c; in a third case, the first telescoping member 121 can be 12c and the second telescoping member 124 can be 12 d. It is understood that in other embodiments, the number of telescoping members 12 can be any number, and is provided according to the specific situation, and the number of telescoping members 12 is not limited herein.

In some embodiments, the delivery tube 118 is helical in whole or in part, or the delivery tube 118 is pleated in whole or in part. In this manner, the delivery tube 118 may be caused to move in cooperation with the retraction assembly 110.

Referring to fig. 3, in the illustrated embodiment, the delivery pipe 118 is generally helical and is housed in the housing space 120.

It will be appreciated that, when the telescopic assembly 110 is extended or retracted, the conveying pipe 118 is driven to move along the extension or retraction direction of the telescopic assembly 110. If the length of the delivery tube 118 is less than the maximum length of the retraction assembly 110, the delivery tube 118 may be stretched to break the delivery tube 118 or the delivery tube 118 may become disconnected from the first port 111 and/or the second port 112.

Referring to fig. 1 again, in the illustrated embodiment, the delivery tube 118 is partially helical, and the helical delivery tube 118 is partially housed in the housing space 120.

In other embodiments, the delivery tube 118 may be coupled to the exterior of the retraction assembly 110 in whole or in part in a helical configuration. Other embodiments are not specifically limited herein.

In addition, the delivery tube 118 may be made of a material having good elasticity. In one example, the delivery tube 118 may be a silicone tube. It will be appreciated that in other examples, the delivery tube 118 may be other flexible or resilient tubes. In this way, the delivery tube 118 is ensured to move in response to the telescoping of the telescoping assembly 110 in a timely manner, while being less prone to breakage.

In addition, in the case where the duct 118 is folded in whole or in part, the duct 118 is provided with a plurality of folds in whole or in part of the duct wall. In this way, the delivery tube 118 may unfold or fold along the crease when the delivery tube 118 is stretched or compressed.

Referring to fig. 9, a conveying device 10 according to an embodiment of the present invention includes the conveying component 11 according to any one of the embodiments, and a power component 23 connected to the conveying component 11, where the power component 23 is used for conveying a first fluid and a second fluid.

In the above-mentioned delivery device 10, the telescopic assembly 110 is provided to reduce the space occupied by the household appliance 20, and the space required by the telescopic assembly 110 in the process of telescopic is also small. The delivery pipe 118 can cooperate with the functional requirements of the household appliance 20 to realize the action on the second fluid without manual operation, so that the household appliance 20 is more intelligent, the working efficiency is improved, and the service time is shortened.

Specifically, referring to fig. 9-10, a conveying pipeline structure for conveying fluid is connected between the power component 23 and the conveying component 11.

When the first fluid is gas, the power part 23 may comprise a power device such as an air pump; when the first fluid is a liquid, the power part 23 may comprise a power device such as a water pump; when the second fluid is gas, the power part 23 may comprise a power device such as an air pump; when the second fluid is a liquid, the power unit 23 may comprise a power device such as a water pump.

Further, in the case where the power unit 23 can deliver liquid and gas, the power unit 23 may include a combination of an air pump and a water pump, and the air pump and the water pump in the power unit 23 may be operated separately. Of course, the power unit 23 is not limited to the air pump and the water pump. In certain embodiments, the power component 23 may comprise a hydraulic machine. The power unit 23 is not particularly limited herein.

In one example, the delivery device 10 is further provided with a pressurizing device for engaging the power member 23. In this manner, when the power component 23 is used to deliver the first fluid and/or the second fluid, a greater fluid pressure may be provided, which may enhance the cleaning effect of the delivery device 10.

Referring to fig. 8-10, a household appliance 20 according to an embodiment of the present invention includes a main body 21 and a conveying device 10 according to the above embodiment, the main body 21 forms a containing chamber 22, the conveying device 10 is connected to the main body 21, and a telescopic assembly 110 is used to introduce a second fluid into the containing chamber 22 or to guide the second fluid out of the containing chamber 22.

In the household appliance 20, the telescopic assembly 110 is provided to reduce the space occupied by the household appliance 20, and the space required by the telescopic assembly 110 in the telescopic process is also small. The delivery pipe 118 can cooperate with the functional requirements of the household appliance 20 to realize the action on the second fluid without manual operation, so that the household appliance 20 is more intelligent, the working efficiency is improved, and the service time is shortened.

It is understood that the household appliance 20 includes, but is not limited to, electric rice cooker, electric pressure cooker, coffee maker, soybean milk maker, cooking machine, etc. The specific type of the home appliance 20 is not limited herein.

In the illustrated embodiment, the household appliance 20 is an electric rice cooker, and the accommodating chamber 22 can be used for accommodating and cleaning or cooking rice grains, specifically, the accommodating chamber 22 is filled with water through the conveying device 10 to wash and cook rice, so that the electric rice cooker can realize the functions of automatically washing and cooking rice.

In the embodiment shown in fig. 9, the household appliance 20 may comprise an upper body 24. In one embodiment, the upper body 24 may be disposed over the body 21. It is understood that the upper body 24 may serve as an upper cover of the home appliance 20. The upper part body 24 covers the upper part of the body 21, and the quantitative cavity 11 is used for conveying materials downwards into the body 21.

In fig. 9, an inner container 25 is provided in the body 21, the top of the inner container 25 has an opening, and the material can enter the inner container 25 from the top opening of the inner container 25.

In some embodiments, upper body 24 is movably connected to body 21. For example, the upper body 24 is rotatably connected to the main body 21, and the upper body 24 rotates relative to the main body 21 to open or close the top opening of the inner container 25. For another example, the upper body 24 is slidably connected to the main body 21, and the upper body 24 slides relative to the main body 21 to open or close the top opening of the inner container 25. For another example, the upper body 24 is rotatably and slidably connected to the body 21, and the upper body 24 slides with respect to the body 21 to open or close the top opening of the inner container 25, and is rotatably provided at a side of the body 21 with respect to the body 21.

In certain embodiments, upper body 24 is removably coupled to body 21. Specifically, a storage space is provided below the upper body 24. The circumferential direction of the storage space is provided with a circumferential opening, and the body 21 can be taken out of and put into the storage space from the circumferential opening of the storage space. The top of the body 21 is opened with a body opening, and when the body 21 is located in the accommodating space, the quantitative cavity 11 of the upper body 24 can be communicated with the space in the body 21 through the body opening, so that the material in the quantitative cavity can be conveyed into the body 21, for example, the inner container 25.

The upper body 24 may have a flat plate shape, a bent shape, or the like, and the specific shape of the upper body 24 is not particularly limited.

According to the control method of the household appliance 20 provided by the embodiment of the invention, the household appliance 20 comprises the body 21 and the conveying device 10 of the embodiment, and the body 21 is provided with the accommodating chamber 22.

Referring to fig. 11, the control method includes:

step S01, controlling the power component 23 to introduce liquid from the fluid passage 119 so that the liquid enters the accommodating chamber 22;

step S02, controlling the power component 23 to supply fluid to the accommodating space 120 to drive the expansion assembly 110 to extend;

step S03, controlling the power component 23 to transfer gas and/or liquid from the fluid channel 119 to the liquid in the accommodating chamber 22 when the telescopic assembly 110 is extended;

in step S04, when the expansion/contraction assembly 110 is expanded, the power unit 23 is controlled to stop supplying the gas and/or the liquid, and the power unit 23 is controlled to draw the liquid in the accommodation chamber 22 through the fluid passage 119.

In the control method, the power component 23 is controlled to selectively convey liquid or gas into the accommodating chamber 22, the liquid is extracted from the accommodating chamber 22, and the telescopic state of the telescopic assembly 110 in the body 21 is controlled, so that the power component 23 and the telescopic assembly 110 are matched with each other, the automatic operation of the conveying device 10 in the accommodating chamber 22 is realized, the household appliance 20 is more intelligent, the working efficiency is improved, and the service time is shortened.

In particular, the household appliance 20 may also be provided with an operation interface for operating the household appliance 20 by a user, and a circuit configuration. The operation interface is electrically connected to the circuit device, which is electrically connected to the power unit 23. The power unit 23 has the functions of liquid inlet, liquid extraction, air inlet and air extraction. In one example, in the event that the operator interface receives an actuation of the inlet, the circuit arrangement may activate the power member 23, and the power member 23 may begin to feed the inlet along the duct 118 into the receiving chamber 22.

In another example, the first fluid is a gas and the second fluid is a liquid. The circuit means may provide a command to the power unit 23, and the power unit 23 may supply liquid to the fluid passage 119, and the liquid may be introduced into the accommodating chamber 22 along the delivery pipe 118. Then, the power unit 23 may also inject air into the accommodating space 120, and the air drives the expansion assembly 110 to expand.

In other embodiments, the home appliance 20 may be provided with the first condition and the second condition. Specifically, after the telescopic assembly 110 is extended, if the liquid in the accommodating chamber 22 satisfies the first condition, the circuit device may send a command to the power component 23, and the power component 23 stops introducing the liquid into the accommodating chamber 22, so that the second port 112 is located below the liquid level. At this point, the power component 23 may begin to inject gas into the housing chamber 22, which is injected into the liquid at the second port 112. Thus, the liquid in the accommodating chamber 22 is turned over due to the continuous air intake, and in the case that the household appliance 20 is an electric rice cooker, the rice grains can be turned over in the accommodating chamber 22 to wash the rice with bubbles.

Specifically, when the liquid in the accommodating chamber 22 satisfies the second condition, the circuit device may send a command to the power component 23, and the power component 23 stops introducing the gas into the accommodating chamber 22. At this point, retraction assembly 110 is still in an extended state, i.e., second port 112 is still below the fluid level. The circuit arrangement may provide a command to the power unit 23 that the power unit 23 begins to draw fluid from the chamber 22 along the fluid delivery line 118 through the second port 112. Thus, the liquid pumping function is realized.

It should be noted that the first condition of the household appliance 20 can be set by taking different parameters, such as the volume of liquid injected by the power component 23 into the housing chamber 22.

Specifically, when the liquid volume in the accommodating chamber 22 reaches a set value, such as 2 liters, the first condition may be considered to be satisfied. Of course, the time for injecting the liquid into the accommodating chamber 22 by the power unit 23 may be 20 seconds, for example. Specifically, when the power member 23 injects the liquid into the accommodating chamber 22 for 20 seconds, the first condition may be considered to be satisfied.

Similarly, the second condition of the household appliance 20 can be set by adopting different parameters, such as the volume of the gas injected into the accommodating chamber 22 by the power component 23, or the time for injecting the gas into the accommodating chamber 22 by the power component 23, and specifically, the examples given with respect to the first condition can be referred to, and will not be described in detail herein.

In addition, the first condition and/or the second condition of the household appliance 20 may be preset conditions, or may be changed or adjusted according to specific situations.

Specifically, in one example, the operation interface of the home appliance 20 may be provided with a structure for adjusting the first condition and/or the second condition, such as a button, a touch screen. In this way, the user can operate according to specific conditions. The first condition and/or the second condition in other embodiments are not limited herein.

Specifically, the control method is further described below with the household appliance 20 as an electric rice cooker.

In this embodiment, referring to fig. 12, in step S01, when a certain amount of rice grains are transported in the accommodating chamber 22, the user can operate the household appliance 20, and the household appliance 20 controls the power unit 23 to feed the liquid into the accommodating chamber 22 along the fluid passage 119, so that the rice grains are all immersed in the liquid. Thus, conditions are provided for realizing the rice washing function.

In step S02, the gas pressure in the telescopic assembly 110 is increased by gradually introducing gas into the accommodating space 120, so that the telescopic assembly 110 can be extended in the telescopic direction. Thus, conditions are provided for improving the rice washing effect.

In other embodiments, step S01 and step S02 may be performed simultaneously. That is, while the liquid is introduced into the accommodating chamber 22, the fluid (the fluid may be a liquid, a gas, or a mixture of a gas and a liquid) may be introduced into the accommodating space 120, so that the expansion/contraction assembly 110 is expanded. Thus, the household electrical appliance 20 can control the telescopic assembly 110 to feed liquid at different heights along the telescopic direction, and on one hand, the inner wall of the accommodating chamber 22 can be cleaned, so as to prevent materials (such as rice grains) in the accommodating chamber 22 from being attached to the inner wall of the accommodating chamber 22. On the other hand, the waiting time can be reduced, and the efficiency is improved.

In step S03, the retractable assembly 110 is extended to a position below the liquid level in the accommodating chamber 22. The household appliance 20 controls the power unit 23 to feed air or liquid or both air and liquid into the liquid along the fluid passage 119, so that the materials (such as rice grains) are tumbled in the liquid. Therefore, the function of automatically cleaning materials is realized.

In addition, in other embodiments, step S02 and step S03 may be performed simultaneously. In this manner, the household appliance 20 can control the intake and/or intake of air at different heights of the telescopic assembly 110 along the telescopic direction. So, for only the feed liquor, carry out the rice washing mode of drawing liquid again, can make the grain of rice in the accommodation chamber 22 fully roll in liquid, avoided because the problem that the rice of washing that leads to at the dead angle is not in place, realize that the three-dimensional rice of washing for the cleaning performance is better.

In step S04, the retraction assembly 110 remains extended and extended below the liquid level in the accommodation chamber 22. The household appliance 20 can control the braking force component 23 to stop the air and/or liquid from entering the containing chamber 22. At this time, the home appliance 20 may control the braking force member 23 to draw the liquid in the accommodating chamber 22 along the fluid passage 119. Therefore, liquid used for cleaning the materials can be pumped out, and the liquid used for cleaning the materials is not required to be poured out by a user.

It is understood that the home appliance 20 may set the order of the operation steps according to circumstances, such as the home appliance 20 may repeat the steps S01 and S03 a plurality of times after performing the step S02, thereby securing the rice washing effect of the home appliance 20. Alternatively, after the rice washing function is completed, the household appliance 20 may separately perform the operation of step S01 to deliver the liquid for cooking to the accommodating chamber 22 without providing a liquid inlet. Thus, the structure is prevented from being too complicated.

In addition, for the operation steps of the household appliance 20, a time interval may be set. For example, in step S04, a preset time may be set between the stop of the liquid feeding operation and the liquid pumping operation of the household appliance 20. Specifically, in the case where the liquid supplied in step S04 has the condition for washing the materials or cooking the materials, the home appliance 20 performs the liquid drawing within a preset time after controlling the power part 23 to stop supplying the liquid. After the time reaches the preset time, the household appliance 20 controls the power component 23 to perform the liquid pumping operation. Preferably, the amount of liquid drawn by the power member 23 can be specifically set.

For example, when rice is cooked, sugar in the rice grains partially precipitates into the liquid. In this manner, by performing the liquid drawing operation of step S04, the conveying device 10 can draw out the liquid having a high sugar content during the rice cooking process. Therefore, the sugar content of the rice is low, and the rice is suitable for users with high blood sugar, especially hyperglycemia.

Referring to fig. 13, in some embodiments, the control method further includes:

in step S10, after the liquid in the accommodating chamber 22 is extracted, the power unit 23 is controlled to stop supplying the fluid to the accommodating space 120 to contract the expansion assembly 110. In this way, the retraction assembly 110 can be automatically retracted after completing the work, and does not occupy a large space.

Specifically, after step S04 has been performed, the controllable braking force component 23 stops the gas from being introduced into the accommodating space 120. Retraction of the retraction assembly 110 in the retraction direction is enabled by the reduction of air pressure within the retraction assembly 110.

In one example, the power member 23 can suck the air in the receiving space 120, and a negative pressure is formed in the receiving space 120, so that the retraction assembly 110 retracts in the retraction direction.

In another example, the conveying member 11 may be provided with a restoring member 137. Retraction assembly 110 may be actuated to retract via reset 137. After the power member 23 stops supplying air to the accommodating space 120, the retraction assembly 110 retracts in the retraction direction.

In yet another example, the restoring member 137 may cooperate with the power member 23. When the power member 23 can suck the gas in the receiving space 120, the restoring member 137 can generate a force for retracting the telescopic assembly 110 in accordance with the negative pressure generated in the receiving space 120.

Referring to fig. 14, an embodiment of the present invention provides a method for controlling a household appliance 20, where the household appliance 20 includes a main body 21 and the transportation device 10 of the above embodiment, and the main body 21 forms an accommodating chamber 22.

The control method comprises the following steps:

step S21, controlling the power component 23 to supply fluid to the accommodating space 120 to drive the expansion assembly 110 to extend;

step S22, controlling the power unit 23 to transfer the liquid from the fluid passage 119 into the accommodation chamber 22 when the expansion unit 110 is expanded;

in step S23, when the expansion/contraction unit 110 expands, the power unit 23 is controlled to stop supplying the liquid, and the power unit 23 is controlled to draw the liquid in the accommodation chamber 22 through the fluid passage 119.

In the control method, the power part 23 is controlled to convey liquid into the accommodating chamber 22, the liquid is extracted from the accommodating chamber 22, and the extension state of the telescopic assembly 110 in the body 21 is controlled, so that the power part 23 and the telescopic assembly 110 are matched with each other, the automatic operation of the conveying device 10 in the accommodating chamber 22 is realized, the household appliance 20 is more intelligent, the working efficiency is improved, and the using time is shortened.

In one example, the fluid introduced into the receiving space 120 may be gas. In step S21, the expansion unit 110 is subjected to the action of the air pressure by continuously introducing air into the accommodating space 120, so that the expansion unit 110 can expand along the expansion direction.

In step S22, when the expansion/contraction unit 110 is extended, a certain amount of liquid is transported in the housing chamber 22, and the liquid is added into the housing chamber 22 to process the material or the housing chamber 22. For example, cleaning the contents, cleaning the holding chamber 22 or cooking contents, etc.

Specifically, in the case of a certain amount of material in the housing chamber 22, the material can be cleaned or cooked by feeding the fluid into the housing chamber 22 along the fluid passage 119. After the material cleaning operation is completed, step S23 is performed, and the cleaned liquid or the excess liquid can be pumped away.

In step S23, the electric home appliance 20 may control the braking force component 23 to stop feeding liquid into the accommodating chamber 22. At this time, the telescopic assembly 110 is extended and extended below the liquid level of the accommodating chamber 22. Along the fluid passage 119, the household appliance 20 can control the power component 23 to draw out the liquid in the housing chamber 22. Thus, the liquid discharging function is realized.

In addition, for the operation steps of the household appliance 20, a time interval may be set. For example, in step S23, a preset time may be set between the stop of the liquid feeding operation and the liquid pumping operation of the household appliance 20. Specifically, in the case where the liquid supplied in step S23 has the condition for washing the materials or cooking the materials, the home appliance 20 performs the liquid drawing within a preset time after controlling the power part 23 to stop supplying the liquid. After the time reaches the preset time, the household appliance 20 controls the power component 23 to perform the liquid pumping operation. The amount of liquid drawn by the power unit 23 can be specifically set.

For example, when rice is cooked, sugar in the rice grains partially precipitates into the liquid. In this manner, by performing the liquid drawing operation of step S23, the conveying device 10 can draw out the liquid having a high sugar content during the rice cooking process. Therefore, the sugar content of the rice is low, and the rice is suitable for users with high blood sugar, especially hyperglycemia.

Referring to fig. 15, in some embodiments, the control method includes:

in step S30, when the expansion/contraction unit 110 is expanded and the power member 23 is controlled to feed the liquid from the fluid passage 119 into the housing chamber 22, the power member 23 is controlled to feed the gas from the fluid passage 119 into the housing chamber 22.

Referring to fig. 16, in some embodiments, the control method includes:

in step S31, when the expansion/contraction unit 110 is expanded, the power member 23 is controlled to feed the liquid from the fluid passage 119 into the accommodation chamber 22, and then the power member 23 is controlled to feed the gas from the fluid passage 119 into the accommodation chamber 22.

So, can make the material roll in liquid, promote the washing material effect.

It will be appreciated that the material is displaced in the liquid by the gas, thereby causing the material to move in the liquid. In addition, the materials collide with each other in the liquid, so that stains on the materials can be shaken off, and the cleaning effect is improved.

Referring to fig. 17, in some embodiments, the control method includes:

in step S40, after the liquid in the accommodating chamber 22 is extracted, the power unit 23 is controlled to stop supplying the fluid to the accommodating space 120 to contract the expansion assembly 110. In this way, the retraction assembly 110 can be automatically retracted after completing the work, and does not occupy a large space.

Specifically, after step S23 has been performed, the controllable braking force component 23 stops the gas from being introduced into the accommodating space 120. Retraction of retraction assembly 110 in the retraction direction is enabled by the reduction of the internal air pressure within retraction assembly 110.
