[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will further describe the embodiments of the present application in combination with the drawings.

[0031] The following description of the embodiments with reference to the drawings is not representative of all embodiments consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

The character " / " generally represents the relationship between the front and rear associated objects as "or".

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments, and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] The present application provides a dishwasher for automatically brushing and cleaning dishes, pots, bowls, cups and the like. The dishwasher has an upper machine body and a base assembly 1 fixedly connected with the upper machine body. It can be understood that the upper machine body is configured to include, but not limited to, a heating element for sterilizing and disinfecting the dishes, a spray cleaning element for cleaning the dishes, and a driving element for driving the spray cleaning element to rotate and / or move. The base assembly 1 includes a base 11 and a water inlet valve body 15 for stabilizing water pressure and adjusting water flow. The base 11 has a base inner cavity 112 formed therein. A supply and discharge through hole 111 is formed in the cavity side wall of the base inner cavity 112. The supply and discharge through hole 111 is used to install a waterway element. In the present embodiment, the water inlet valve body 15 is used as the waterway element. The water inlet valve body 15 is located in the base inner cavity 112 and is fixedly installed in the supply and discharge through hole 111.

[0035] Specifically, the water inlet valve body 15 has a water inlet port. The water inlet port of the water inlet valve body 15 is inserted into the supply and discharge through hole 111 and extends through the supply and discharge through hole 111 to form an outer port for connecting an external water supply pipe towards the outside of the base 11. The water inlet valve body 15 also has a water outlet port for connecting an internal conduit. Alternatively, the water inlet valve body 15 and a pipe connector are both used as waterway elements. The water inlet valve body 15 is installed in the supply and discharge through hole 111 through the pipe connector. That is, the pipe connector has a first end and a second end. The first end of the pipe connector is inserted into the supply and discharge through hole 111 and extends out of the supply and discharge through hole to form an outer port for connecting an external water supply pipe. The second end of the pipe connector is detachably connected with the water inlet valve body 15.

[0036] During long-term use of the dishwasher, the connection between the internal conduit and the water inlet valve body 15 and the connection between the water inlet valve body 15 and the pipe connector are prone to overflow and water leakage. This causes the leaked liquid to accumulate in the base inner cavity 112, which increases the risk of short circuit of electrical elements in the base inner cavity 112.

[0037] To solve the above problems, as shown in Figure 1 and Figure 2 , a flow guide channel 118 is formed in the base 11 from the cavity side wall to the cavity bottom wall 113 of the base 11. The width of the flow guide channel 118 is equal to or greater than the diameter of the supply and discharge through hole 111. The flow guide channel 118 is located below the supply and discharge through hole 111 and is used to guide the liquid leaked from the waterway element to the cavity bottom wall 113. In this way, the liquid leaked from the waterway element can be directed to the lowest part of the cavity bottom wall 113 without spreading.

[0038] Further, the base assembly 1 further comprises a pre-warning detection member 12, which is preferably a liquid level detection element, such as a float liquid level meter. The pre-warning detection member 12 can also be a detector element, such as a microwave detector, an infrared detector. The pre-warning detection member 12 can also be a sensor element. The pre-warning detection member 12 is arranged on the cavity bottom wall 113 of the base inner cavity 112, that is, the pre-warning detection member 12 is preferably arranged at the lowest position of the cavity bottom wall 113, so that the pre-warning detection member 12 can timely detect the liquid seeped out of the waterway element and simultaneously send a pre-warning signal to prevent overflow from occurring, thereby effectively preventing the dishwasher from accumulating a large amount of water, and personnel can drain water according to the pre-warning signal.

[0039] As a preferred mode of the present embodiment, as shown in Figure 1 and Figure 2 , the base 11 further comprises a base body and an overflow flow guide portion 13 connected with the base body. The connection here is preferably one-piece forming, so as to reduce the assembly difficulty of the base assembly 1 and ensure that the assembly of the overflow flow guide portion 13 and the base body is more stable. The connection between the overflow flow guide portion 13 and the base body can also be a plug-in connection, so that the overflow flow guide portion 13 can be produced separately, which is also conducive to subsequent disassembly and cleaning. The overflow flow guide portion 13 extends from the cavity side wall to the cavity bottom wall 113, and the overflow flow guide portion 13 is internally provided with a flow guide channel 118. Specifically, the overflow flow guide portion 13 is arranged below the feed-and-drain through hole 111, and the base 11 has a base base surface for abutting against a building body (such as the ground, the countertop, etc.). The direction from the base base surface and perpendicular to the base base surface is the height direction H of the base 11, and the feed-and-drain through hole 111 is preferably located directly above the overflow flow guide portion 13. The overflow flow guide portion 13 comprises a side flow guide body and a bottom flow guide body fixed to the side flow guide body, the side flow guide body extends from the cavity bottom wall 113 to the cavity side wall along the height direction H, and the bottom flow guide body extends from the cavity side wall towards the side close to the pre-warning detection member 12.

[0040] In this way, the liquid seeped out of the waterway element can be directed by the overflow flow guide portion 13 to the cavity bottom wall 113 of the base inner cavity 112 and collected towards the side close to the pre-warning detection member 12, so as to be timely monitored by the pre-warning detection member 12 and remind personnel to drain water and perform maintenance.

[0041] In the long-term use of the dishwasher, the position where the above-mentioned outer port is connected with the external water supply pipe is also prone to overflow and water seepage, and the seeped liquid will cause a large amount of water to accumulate outside the base 11 and cause serious waste.

[0042] As a preferred mode of the present embodiment, as shown in Figure 3 and Figure 4As shown, the overflow guide part 13 further has a guide part body 131 and an external water end 133, the guide part body 131 is internally provided with a guide cavity 132, the guide cavity 132 is part of the guide channel 118, the extension direction of the guide cavity 132 is perpendicular to the cavity side wall, and in the height direction H of the base 11, the slot of the guide cavity 132 faces the feed and drain through hole 111, so that the part of the liquid seeped out by the waterway element can be received by the guide cavity 132, thereby ensuring that the liquid seeped out by the waterway element can be completely guided to the lowest part of the cavity bottom wall 113.

[0043] Further, as shown in Figure 3 and Figure 4 , the external water end 133 protrudes out of the base body and is located below the outer port formed by the extension of the waterway element out of the feed and drain through hole 111, the external water end 133 is internally provided with a water receiving groove, the water receiving groove is communicated with the guide channel 118, the opening of the water receiving groove faces the outer port, that is, the opening of the external water end 133 faces the outer port of the feed and drain through hole 111, the opening of the external water end 133 is upwardly arranged, so that the liquid overflowed and leaked at the position where the outer port is connected with the external water pipe will be received by the water receiving groove of the external water end 133 and guided into the guide channel 118, and finally drained to the lowest part of the cavity bottom wall 113 through the guide channel 118. It can be understood that the base body is arranged between the water receiving groove and the guide channel 118, and the water receiving groove is communicated with the guide channel 118 through the guide cavity 132. It can be understood that, as shown in Figure 3 , the side of the water receiving groove of the external water end 133 away from the guide part body 133 is protrusively formed with an anti-overflow groove wall 137 along the height direction H of the base 11, the two ends of the anti-overflow groove wall 137 are respectively connected with the two opposite groove walls of the water receiving groove, thereby ensuring that the liquid falling into the water receiving groove will not flow out of the water receiving groove again.

[0044] As a preferred mode of the present embodiment, as shown in Figure 3 , the internal part of the external water end 133 is provided with a plurality of separation protrusions 135, the plurality of separation protrusions 135 are arranged at intervals, the extension direction of each separation protrusion 135 is consistent with the extension direction T of the guide cavity 132, that is, each separation protrusion 135 extends from the anti-overflow groove wall 137 towards the guide channel 118, and the separation protrusion 135 separates the water receiving groove to form a plurality of separated grooves 138 communicated with the guide channel 118. Preferably, one end of each separation protrusion 135 close to the guide channel 118 extends into the internal cavity 112 of the base.

[0045] Thus, since the width of each of the separation grooves 138 is smaller than the width of the water receiving groove, larger sundries will not fall into the water receiving groove of the outer water receiving end 133 and finally enter the flow guide cavity 132 and the inner cavity 112 of the base, thereby better protecting the hygiene of the water receiving groove and the inner cavity 112 of the base and ensuring that the liquid exuded by the waterway component can smoothly flow through the separation grooves 138, the flow guide cavity 132, the flow guide channel 118, and finally collect at the lowest part of the cavity bottom wall 113, thereby ensuring that the early warning detection component 12 can make timely monitoring.

[0046] As a preferred mode of the present embodiment, as shown in Figure 3 , the overflow flow guide part 13 further has an outer blocking body 114, which is arranged above the separation protrusions 135,

[0047] The outer blocking body 114 is arranged on the side of the flow guide cavity 132 close to the outer water receiving end 133 and extends from the top side wall of the flow guide cavity 132 toward the side of the separation protrusions 135. Preferably, the outer blocking body 114 is connected to the separation protrusions 135 on the side close to the separation protrusions 135, which can be abutment or integrally formed. The size of the first through opening formed by the adjacent two separation protrusions 135 and the outer blocking body 114 and the size of the second through opening formed by the separation protrusions 135, the outer blocking body 114, and the side wall of the outer water receiving end 133 are both much smaller than the size of the flow guide cavity 132 in the cross section, thereby further blocking larger sundries from entering the flow guide cavity 132 and more effectively protecting the hygiene of the inner cavity 112 of the base.

[0048] As another preferred mode of the present embodiment, as shown in Figure 5 , the part of the separation protrusions 135 extending into the flow guide cavity 132 is protruded and formed with a support body 136 toward the top side wall of the flow guide cavity 132. Understandably, when there are multiple separation protrusions 135, some of the separation protrusions 135 can be protruded and formed with a support body 136 toward the top side wall of the flow guide cavity 132, or each of the separation protrusions 135 can be protruded and formed with a support body 136 toward the top side wall of the flow guide cavity 132. The support body 136 is preferably connected to the top side wall of the flow guide cavity 132, and the support body 136 is fixedly connected to the top side wall of the flow guide cavity 132.

[0049] Thus, this not only further blocks larger sundries from entering the flow guide cavity 132, but also more effectively protects the hygiene of the flow guide cavity 132 and the inner cavity 112 of the base. At the same time, the support body 136 and the separation protrusions 135 can be combined to form a reinforcing rib structure, thereby enhancing the overall structural strength of the base 11.

[0050] It should be noted that, in particular, please refer to Figure 3 , Figure 4 andFigure 5 As shown, the above-mentioned method of setting the outer blocking body 114 is combined with the method of setting the support body 136. The outer blocking body 114 can be connected to the support body 136. This connection can be selected as an abutment connection, a plug-in connection, or an integral molding.

[0051] Preferably, the bottom sidewall of the flow guiding cavity 132 extends obliquely from the side of the external water inlet 133 toward the side of the bottom wall 113 of the inner cavity 112 of the base. In this way, the liquid falling into the external water inlet 133 will not stagnate in the external water inlet 133, but will flow along the extension direction T of the flow guiding cavity 132 to the bottom wall 113 of the inner cavity 112 of the base under the guidance of the bottom sidewall of the obliquely set flow guiding cavity 132. This allows the early warning detection element 12 to make monitoring more timely, thereby ensuring that personnel can make timely judgments and take appropriate measures.

[0052] As a preferred embodiment, please refer to the following for details. Figure 1 and Figure 2 As shown, the bottom wall 113 of the cavity has a drainage portion 115. The drainage portion 115 extends obliquely from the side near the overflow guide portion 13 toward the warning detection element 12. The warning detection element 12 is preferably located at the lowest point in the middle of the inner cavity 112 of the base. The drainage portion 115 is inclined downward from the side near the overflow guide portion 13 toward the lowest point in the middle of the inner cavity 112 of the base. The drainage portion 115 is preferably an arc-shaped surface, or it can be a plane, so that the liquid seeping out of the water circuit element and the liquid seeping out of the connection between the above-mentioned outer port and the external water supply pipe can all flow to the warning detection element 12, so that the warning detection element 12 can make timely detection.

[0053] Furthermore, please refer to the specific details. Figure 1 and Figure 2 As shown, the base assembly 1 also includes a chassis cover 14. A collection groove 116 is provided on one side of the drainage portion 115 where the early warning detection element 12 is located. That is, the collection groove 116 is formed in the middle of the inner cavity 112 of the base. Liquid falling onto the drainage portion 115 will be guided by the guide portion and collected into the collection groove 116. This not only prevents liquid falling onto the bottom wall 113 of the cavity from spreading and affecting the use of other electrical components, but also facilitates rapid detection by the early warning detection element 12. The chassis cover 14 is embedded inside the collection groove 116, and the early warning detection element 12 is mounted and fixed on the chassis cover 14.

[0054] For details, please refer to Figure 2 As shown, the chassis cover 14 includes a detection fixing seat 141 and a movable float 142, as... Figure 6As shown, the inside of the detection fixed seat 141 is provided with a fixed seat cavity, and the movable float 142 is movably disposed in the fixed seat cavity. The detection fixed seat 141 is provided with a flow port 143 on the side of the bottom of the collection tank 116. After the liquid flows into the bottom of the collection tank 116, it will form water accumulation. However, when the amount of water accumulation increases, the liquid level rises, and the movable float 142 will also move upward accordingly. Furthermore, the warning detection element 12 is installed and fixed on the top of the detection fixing seat 141 of the chassis cover 14. Specifically, the top of the detection fixing seat 141 is provided with a warning embedding groove 147 for embedding and fixing the warning detection element 12. The detection fixing seat 141 is provided with a detection port, and the movable float 142 is provided with a detection protrusion 144. When the detection protrusion 144 of the movable float 142 moves toward the detection port, the detection port of the warning detection element 12 detects the detection protrusion 144 through the detection port. The warning detection element 12 converts the liquid level change into an electrical signal or a mechanical displacement signal and transmits it to the control element of the dishwasher. After conversion and processing by the control element, a display warning signal and / or an audible warning signal are formed, thereby achieving the purpose of liquid level measurement and warning.

[0055] To ensure that the detection port of the early warning detection component 12 can accurately detect the detection protrusion 144 of the active float 142, such as Figure 6 As shown, preferably, a positioning protrusion 117 is formed on the bottom wall 113 of the inner cavity 112 of the base. The positioning protrusion 117 is located in the collecting groove 116. The movable float 142 is provided with a movable positioning hole 145 that inserts into and passes through the positioning protrusion 117. The movable positioning hole 145 slides with the positioning protrusion 117. When the liquid level rises, the movable float 142 rises along the protrusion direction of the positioning protrusion 117. Furthermore, the detection fixing seat 141 is provided with a fixing assembly hole 146 for inserting the positioning protrusion 117, thereby realizing that the detection fixing seat 141 is fixedly connected to the base 11 through the positioning protrusion 117.

[0056] Preferably, please refer to the following for details. Figure 1 and Figure 2 As shown, the drainage section 115 extends along the circumferential direction of the collecting tank 116. This arrangement greatly increases the drainage area of ​​the drainage section 115, thereby ensuring that the liquid falling towards the bottom wall 113 of the cavity can be within the range of the drainage section 115 and eventually guided into the collecting tank 116 for collection.
