Description

Technical Field

[0001] This utility model relates to the field of dishwashers, and in particular to a water tank venting structure and a dishwasher. Background Technology

[0002] Traditional dishwashers typically use a closed design for their water tanks, relying mainly on mechanical valves to regulate water flow or on external pressure relief vents to regulate air pressure, adapting to abnormally high water or air pressure. However, this pressure relief method is prone to blockage, leading to excessive water flow and air pressure that cannot be released in time, causing the water tank to deform or even burst, affecting the product's lifespan and the equipment's safety. Utility Model Content

[0003] Therefore, it is necessary to provide a water tank venting structure and a dishwasher to address the problem that traditional dishwasher water tank depressurization methods are prone to causing excessive water flow and air pressure to be unable to be released in time due to channel blockage, which can lead to water tank deformation or even bursting.

[0004] A water tank venting structure includes: an inner liner assembly having a washing chamber; a water tank assembly disposed on the inner liner assembly, having a liquid storage chamber, an overflow port communicating with the liquid storage chamber, and a flow passage communicating with the overflow port; and a locking assembly disposed on the inner liner assembly and / or the water tank assembly, the locking assembly connecting the inner liner assembly and the water tank assembly, the locking assembly having an output port, and the flow passage, the output port, and the washing chamber being sequentially connected.

[0005] The first aspect of this application discloses a water tank venting structure, which sequentially connects a liquid storage chamber, an overflow port, a flow channel, an outlet, and a washing chamber to form a stable pressure relief path. This allows compressed air during liquid injection into the water tank assembly to be transmitted to the washing chamber through the pressure relief path, preventing excessive air pressure from causing the water tank assembly to burst. Furthermore, the pressure relief path is not blocked by external dust or other factors. This design also allows excess water flow to be delivered to the washing chamber through the pressure relief path, preventing excessive liquid volume from causing the water tank assembly to burst, effectively extending the product's lifespan and improving equipment safety. The locking assembly connects the inner tank assembly and the water tank assembly, ensuring good stability and reliability. Moreover, the locking assembly has an outlet that allows airflow and liquid to be delivered to the washing chamber, thus combining structural fixation and airflow / drainage functions. This eliminates the need for additional components for liquid output, optimizing space utilization.

[0006] In one embodiment, the inner tank assembly has an opening located in the extension direction of the flow channel. The opening communicates with both the flow channel and the outlet. The locking assembly is disposed on the inner tank assembly and located at the opening. The opening's communication with both the flow channel and the outlet allows liquid in the flow channel to smoothly pass through the inner tank assembly's shell and enter the washing chamber, ensuring the stability of the pressure relief process. The opening's location in the extension direction of the flow channel shortens the liquid transport distance from the storage chamber to the washing chamber, improving practicality.

[0007] In one embodiment, the water tank assembly includes a sealing groove and a sealing element. The sealing element is disposed on the inner liner assembly and / or the water tank assembly, and is located within the sealing groove. The sealing element is positioned between the inner liner assembly and the water tank assembly, and is used to seal the gap between them. By sealing the gap between the inner liner assembly and the water tank assembly, liquid leakage is prevented, thus avoiding product leakage and impacting the user experience. The sealing groove further enhances the stability and reliability of the sealing element.

[0008] In one embodiment, the flow channel includes a first flow channel and a second flow channel. The second flow channels are multiple and spaced apart, extending in the same direction as the first flow channel. The overflow port, the first flow channel, the multiple second flow channels, and the output port are sequentially connected. The multiple second flow channels, all connected to the output port, allow water to be delivered into the washing chamber through the output ports in various directions. This design is more efficient and effectively disperses the impact force of the water flow on the washing chamber. The fact that the second flow channels are aligned with the first flow channel shortens the air and water transport distance, enabling timely response to pressure reduction and drainage needs.

[0009] In one embodiment, the water tank assembly includes a water tank shell and a flow guide. The water tank shell is disposed on the inner liner assembly and has a liquid storage chamber. The flow guide is disposed on the water tank shell and located within the liquid storage chamber, and has an overflow port and a flow passage. The flow guide creates a stable pressure relief and drainage channel, allowing liquid to automatically flow through the overflow port and flow passage of the flow guide into the washing chamber of the inner liner assembly once a certain liquid level is reached, preventing excessive liquid buildup that could cause the water tank assembly to burst.

[0010] In one embodiment, the water tank housing includes a first housing and a second housing. The first housing is disposed on the inner liner assembly, and the second housing is disposed on the first housing. The second housing and the first housing together form the liquid storage cavity. The flow guide is disposed on either the first housing or the second housing. The separate design of the first and second housings facilitates the disassembly, assembly, and subsequent maintenance of the water tank assembly. The flow guide on either the first or second housing provides a stable supporting foundation, ensuring a stable water flow output.

[0011] In one embodiment, the second housing has a groove communicating with the liquid storage chamber and the overflow port. A guide member is disposed on the first housing, extending towards the groove and / or abutting against the groove wall. Because the second housing has a groove and the overflow port communicates with it, liquid needs to rise to a higher level before it can be fed into the overflow port. This design allows the liquid storage chamber to hold more liquid, thus providing sufficient liquid for other components of the dishwasher, resulting in good practicality.

[0012] In one embodiment, the overflow port is provided at one end of the guide member near the second housing. Because the overflow port is located at the end of the guide member near the second housing, and because the guide member abuts against the second housing, the liquid needs to rise to near the top of the second housing before it can be discharged from the overflow port. This increases the actual usable capacity of the storage chamber, ensuring that the storage chamber can store more liquid and improving the operating efficiency of the equipment.

[0013] In one embodiment, the flow guide includes a flow guide column and protrusions. The flow guide column is disposed on the first housing, and there are multiple protrusions, all disposed on the flow guide column and located at the end of the flow guide column away from the first housing. The multiple protrusions are spaced apart circumferentially along the flow guide column, extending towards the second housing and / or abutting against the second housing. An overflow port is formed between two adjacent protrusions. The formation of multiple overflow ports between the multiple protrusions improves pressure relief efficiency. When liquid is injected, compressed air and excess liquid can be quickly discharged through multiple overflow ports, preventing deformation or bursting of the water tank housing due to excessive air or hydraulic pressure. The multiple protrusions located at the end of the flow guide column away from the first housing require the liquid to rise to a higher level before being discharged through the overflow ports, increasing the actual water storage capacity of the storage chamber.

[0014] In one embodiment, the guide column includes a guide column body, a connecting block, and partitions. The guide column body is disposed on the first housing and has a first flow channel communicating with the overflow port. The connecting block has a second mounting hole for engaging with the locking assembly. Multiple partitions are disposed on the guide column body and the connecting block, spaced circumferentially around the connecting block. The connecting block, two adjacent partitions, and the guide column body together form a second flow channel, which communicates with the first flow channel and the outlet port. By creating multiple second flow channels with partitions spaced circumferentially around the connecting block, the water flow impact force can be dispersed into multiple second flow channels, effectively reducing the water flow impact force. This design optimizes fluid distribution and effectively reduces noise. The second mounting hole of the connecting block, engaging with the locking assembly, securely connects the water tank assembly and the inner liner assembly.

[0015] In one embodiment, the locking assembly includes a fastener and a connector. The fastener is disposed on the inner tank assembly and has an output port. The fastener has a first mounting hole. The connector is disposed on the fastener and passes through the first mounting hole. The water tank assembly has a second mounting hole. The connector passes through the first mounting hole and engages with the second mounting hole. By engaging with the second mounting hole of the water tank assembly through the first mounting hole of the fastener, a stable mechanical connection is formed between the inner tank assembly and the water tank assembly. The fastener allows the connector to connect the inner tank assembly and the water tank assembly, and the output port allows gas and liquid in the storage chamber to be transported to the washing chamber. Thus, the fastener integrates multiple functions, simplifies the structure, and optimizes space utilization.

[0016] In one embodiment, the fastener includes a protrusion, a support base, and protrusions. The protrusion is disposed on the inner tank assembly and / or the water tank assembly, and the protrusion has the first mounting hole. The support base is disposed on the protrusion, and there are multiple protrusions, all disposed on the support base. The multiple protrusions are spaced apart circumferentially along the support base, and the output port is formed between two adjacent protrusions. The protrusions allow the fastener to be more stably fixed to the inner tank assembly via the connector. The multiple output ports formed between the multiple protrusions allow airflow and water flow to be delivered into the washing chamber from multiple directions, effectively transporting airflow and liquid and significantly optimizing space utilization.

[0017] A dishwasher includes: the aforementioned water tank venting structure.

[0018] The second aspect of this application discloses a dishwasher that utilizes an overflow port, a flow channel, and an output port in its water tank venting structure to form a stable conveying channel. This allows for the timely discharge of compressed air and excess liquid from the water tank caused by liquid injection, preventing the water tank assembly from bursting due to excessive air or hydraulic pressure. This design significantly improves the dishwasher's safety performance and reduces the risk of equipment malfunction. The locking assembly not only connects the inner tank assembly and the water tank assembly but also serves as a flow guide and air guide, making it highly practical. Attached Figure Description

[0037] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0039] Example 1

[0040] like Figure 1-4 and Figure 6 As shown, this embodiment discloses a water tank venting structure, including: an inner liner assembly 1, the inner liner assembly 1 having a washing chamber 101; a water tank assembly 2, the water tank assembly 2 being disposed on the inner liner assembly 1, the water tank assembly 2 having a liquid storage chamber 201, the water tank assembly 2 having an overflow port 202 communicating with the liquid storage chamber 201, the water tank assembly 2 having a flow passage 203 communicating with the overflow port 202; and a locking assembly 3, the locking assembly 3 being disposed on the inner liner assembly 1 and / or the water tank assembly 2, the locking assembly 3 being used to connect the inner liner assembly 1 and the water tank assembly 2, the locking assembly 3 having an output port 301, the flow passage 203, the output port 301 and the washing chamber 101 being sequentially connected.

[0041] The first aspect of this application discloses a water tank venting structure. A liquid storage chamber 201, an overflow port 202, a flow channel 203, an output port 301, and a washing chamber 101 are sequentially connected to form a stable pressure relief path. This allows compressed air from the water tank assembly 2 during liquid injection to be transmitted to the washing chamber 101 through the pressure relief path, preventing excessive air pressure from causing the water tank assembly 2 to burst. Furthermore, the pressure relief path will not be blocked by external dust or other factors. This design also allows excess water to be delivered to the washing chamber 101 through the pressure relief path, preventing excessive liquid volume from causing the water tank assembly 2 to burst, effectively extending the product's service life and improving equipment safety. The locking component 3 connects the inner tank assembly 1 and the water tank assembly 2 together, ensuring good stability and reliability. Furthermore, the locking assembly 3 is provided with an output port 301 that allows airflow and liquid to be delivered into the washing chamber 101. Thus, the locking assembly 3 has both structural fixing and airflow guiding functions, eliminating the need for additional components for liquid output and optimizing space utilization.

[0042] like Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner liner assembly 1 is provided with an opening 102, the opening 102 is located in the extending direction of the flow channel 203, the opening 102 communicates with the flow channel 203 and the output port 301 respectively, and the locking assembly 3 is disposed on the inner liner assembly 1 and located at the opening 102. By communicating with the flow channel 203 and the output port 301 through the opening 102, the liquid in the flow channel 203 can smoothly pass through the shell of the inner liner assembly 1 and enter the washing chamber 101, ensuring the stability of the pressure relief process. Because the opening 102 is located in the extending direction of the flow channel 203, the transport distance of the liquid in the storage chamber 201 to the washing chamber 101 is shortened, resulting in good practicality.

[0043] like Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water tank assembly 2 is provided with a sealing groove 204, and also includes a sealing element 4. The sealing element 4 is disposed on the inner liner assembly 1 and / or the water tank assembly 2, and the sealing element 4 is located at the sealing groove 204. The sealing element 4 is located between the inner liner assembly 1 and the water tank assembly 2, and the sealing element 4 is used to seal the gap between the inner liner assembly 1 and the water tank assembly 2. By sealing the gap between the inner liner assembly 1 and the water tank assembly 2 with the sealing element 4, liquid leakage from the gap between the inner liner assembly 1 and the water tank assembly 2 is prevented, which would affect product leakage and thus affect the user's experience. The sealing groove 204 makes the sealing element 4 more stable and reliable.

[0044] like Figure 6 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the flow channel 203 includes a first flow channel 2031 and a second flow channel 2032, the number of second flow channels 2032 is multiple and the multiple second flow channels 2032 are arranged at intervals, the extension direction of the second flow channels 2032 is the same as that of the first flow channel 2031, and the overflow port 202, the first flow channel 2031, the multiple second flow channels 2032 and the output port 301 are sequentially connected. Because there are multiple second flow channels 2032, all of which are connected to the output port 301, water is transported to the washing chamber 101 through the output ports 301 in various directions. This design is more reasonable and can effectively disperse the impact force of the water flow on the washing chamber 101. Because the second flow channels 2032 are in the same direction as the first flow channels 2031, the transport distance of airflow and water flow is shortened, enabling timely response to the need for pressure reduction and drainage.

[0045] like Figure 7 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water tank assembly 2 includes a water tank shell 21 and a flow guide 22. The water tank shell 21 is disposed on the inner tank assembly 1, and the water tank shell 21 has the liquid storage chamber 201. The flow guide 22 is disposed on the water tank shell 21 and located within the liquid storage chamber 201. The flow guide 22 has the overflow port 202 and the flow passage 203. The flow guide 22 forms a stable pressure relief and drainage channel, so that when the liquid reaches a certain liquid level, it is automatically transported to the washing chamber 101 of the inner tank assembly 1 through the overflow port 202 and the flow passage 203 of the flow guide 22, avoiding excessive liquid not being discharged in time and causing the water tank assembly 2 to burst.

[0046] like Figure 7 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water tank shell 21 includes a first shell 211 and a second shell 212. The first shell 211 is disposed on the inner liner assembly 1, and the second shell 212 is disposed on the first shell 211. The second shell 212 and the first shell 211 enclose the liquid storage cavity 201, and the flow guide 22 is disposed on the first shell 211 or the second shell 212. The separate design of the first shell 211 and the second shell 212 makes the disassembly and assembly of the water tank assembly 2 and subsequent maintenance more convenient. The flow guide 22, disposed on the first shell 211 or the second shell 212, provides a stable supporting foundation, ensuring a stable water flow output.

[0047] like Figure 4-7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second housing 212 is provided with a groove 205, the groove 205 communicating with the liquid storage chamber 201 and the overflow port 202; the guide member 22 is disposed on the first housing 211, the guide member 22 extending toward the groove 205 and / or the guide member 22 abutting against the groove wall of the groove 205. Because the second housing 212 has a groove 205 and the overflow port 202 communicates with the groove 205, the liquid needs to rise to a higher level before it can be input from the overflow port 202. This design allows the liquid storage chamber 201 to store more liquid, thereby providing sufficient liquid for other components of the dishwasher, resulting in good practicality.

[0048] like Figure 4-7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the overflow port 202 is provided at one end of the guide member 22 near the second housing 212. Because the overflow port 202 is provided at one end of the guide member 22 near the second housing 212, and because the guide member 22 abuts against the second housing 212, the liquid needs to rise to near the top of the second housing 212 before it can be discharged from the overflow port 202. This increases the actual usable capacity of the liquid storage chamber 201, ensuring that the liquid storage chamber 201 can store more liquid and improve the operating efficiency of the equipment.

[0049] like Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the guide member 22 includes a guide column 221 and a boss 222. The guide column 221 is disposed on the first housing 211. The number of bosses 222 is multiple, and all bosses 222 are disposed on the guide column 221 and located at the end of the guide column 221 away from the first housing 211. The multiple bosses 222 are spaced apart circumferentially along the guide column 221. The bosses 222 extend toward the second housing 212 and / or abut against the second housing 212. An overflow port 202 is formed between two adjacent bosses 222. By forming multiple overflow ports 202 between multiple bosses 222, the pressure relief efficiency is improved. When liquid is injected, compressed air and excess liquid can be quickly discharged through multiple overflow ports 202, avoiding deformation or bursting of the water tank housing 21 due to excessive air or hydraulic pressure. By having multiple protrusions 222 located at the end of the guide column 221 away from the first housing 211, the liquid needs to rise to a higher level before it can be discharged through the overflow port 202, thus increasing the actual water storage capacity of the liquid storage chamber 201.

[0050] like Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the guide post 221 includes a guide post body 2211, a connecting block 2212, and a partition block 2213. The guide post body 2211 is disposed on the first housing 211. The guide post body 2211 has a first flow channel 2031 communicating with the overflow port 202. The connecting block 2212 has a second mounting hole 206, which is used to cooperate with the locking assembly 3. The partition block 2213... The number of partitions 2213 is multiple, each disposed on the guide post body 2211 and the connecting block 2212, with the partitions 2213 spaced circumferentially along the connecting block 2212. The connecting block 2212, two adjacent partitions 2213, and the guide post body 2211 enclose a second flow channel 2032, which communicates with the first flow channel 2031 and the outlet 301. By having multiple partitions 2213 spaced circumferentially along the connecting block 2212 to form multiple second flow channels 2032, the water flow impact force can be dispersed into multiple second flow channels 2032, effectively reducing the water flow impact force. This design optimizes fluid distribution and effectively reduces noise. The water tank assembly 2 and the inner liner assembly 1 are securely connected by the second mounting hole 206 of the connecting block 2212 cooperating with the locking assembly 3.

[0051] like Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the locking assembly 3 includes a fastener 31 and a connector 32. The fastener 31 is disposed on the inner liner assembly 1, the fastener 31 has the output port 301, and the fastener 31 has a first mounting hole 302. The connector 32 is disposed on the fastener 31 and passes through the first mounting hole 302. The water tank assembly 2 has a second mounting hole 206. The connector 32 passes through the first mounting hole 302 and engages with the second mounting hole 206. By the connector 32 passing through the first mounting hole 302 of the fastener 31 and engaging with the second mounting hole 206 of the water tank assembly 2, a stable mechanical connection is formed between the inner liner assembly 1 and the water tank assembly 2. The fastener 31 enables the connector 32 to connect the inner tank assembly 1 and the water tank assembly 2 together. The fastener 31 is provided with an outlet 301 so that the gas and liquid in the liquid storage chamber 201 can be transported to the washing chamber 101. Thus, the fastener 31 integrates multiple functions, simplifies the structure, and optimizes the space utilization.

[0052] like Figure 13As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the fastener 31 includes a protrusion 311, a support base 312, and protrusions 313. The protrusion 311 is disposed on the inner tank assembly 1 and / or the water tank assembly 2, and the protrusion 311 has the first mounting hole 302. The support base 312 is disposed on the protrusion 311. There are multiple protrusions 313, all of which are disposed on the support base 312. The multiple protrusions 313 are spaced apart along the circumference of the support base 312, and the output port 301 is formed between two adjacent protrusions 313. The arrangement of the protrusions 311 allows the fastener 31 to be more stably fixed to the inner tank assembly 1 through the connector 32. The multiple output ports 301 formed between the multiple protrusions 313 allow airflow and water flow to be delivered into the washing chamber 101 from multiple directions, effectively transporting airflow and liquid and significantly optimizing space utilization.
