Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a drainage system and a dishwasher thereof. Background Technology

[0002] As a kitchen appliance, dishwashers have become increasingly popular in recent years. To reduce the risk of kitchen flooding due to dishwasher leaks, multiple leak safety alarm control methods have been added to dishwashers.

[0003] Current dishwashers use methods such as float-triggered alarms, high-water-level alarms, and inlet valve pulse-triggered alarms to detect leaks. When a dishwasher leaks, water typically flows to and collects on the base cover, eventually triggering a microswitch to generate an alarm. However, once water accumulates on the base cover, the dishwasher cannot automatically remove it. Repair personnel must remove the dishwasher from the cabinet and empty it to clear the water. When a large amount of water accumulates in the base cover, the user's kitchen floor may be covered in water droplets, especially on wooden floors, increasing the difficulty of repairs and severely impacting the user experience.

Detailed Implementation

[0028] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0029] refer to Figure 1-3 This embodiment provides a drainage system, including a water cup assembly 1, a base cover 2, and a drainage device (not shown in the figure). The water cup assembly 1 has an upward-opening water storage chamber 11, and a net drain outlet 122 communicating with the water storage chamber 11 is provided on the outer wall of the water cup assembly. The base cover 2 is located below the water cup assembly 1 and has an upward-opening water collection chamber 21, which is used to collect water leakage from the dishwasher. The drainage device includes a net drain pump 31, a suction pipe assembly, and a drain pipe assembly. The net drain pump 31 is detachably installed on the water cup assembly 1 and communicates with the net drain outlet 122 of the water cup assembly 1. The net drain pump 31 is connected to the water collection chamber 21 through the suction pipe assembly, and the net drain pump 31 is connected to the sewer through the drain pipe assembly.

[0030] As can be seen, by connecting the drain pump 31 to the drain outlet 122 of the water cup assembly 1, the water collection chamber 21 of the chassis cover 2, and the drain pipe assembly respectively, the residual water in the water cup assembly 1 and the accumulated water on the chassis cover 2 can be discharged automatically and in a timely manner using the same drain pump. This improves the utilization rate of the drain pump, reduces the risk of the cabinet being soaked due to water leakage, reduces the difficulty and cost of maintenance, and improves the user experience.

[0031] Specifically, the drain pump 31 is connected to the water cup assembly 1 and the chassis cover 2 in the following ways, including but not limited to:

[0032] The first type, reference Figure 5 The drain pump 31 is equipped with a cavity (not shown in the figure), a suction port 311, and a discharge port 312. The cavity is connected to the suction port 311 and the discharge port 312. The suction port 311 is connected to the drain outlet 122 and the suction pipe assembly via a three-way valve. The discharge port 312 is connected to the sewer via the drain pipe assembly. This allows the three-way valve to control the suction port 31 to selectively connect to the drain outlet 122 or the suction pipe assembly, thereby controlling the drain pump 31 to drain water from the cup assembly or the chassis cover.

[0033] The second type has a drain pump 31 with a cavity, a suction port 311, a drain inlet, and an outlet 312. The cavity is connected to the suction port 311, the drain inlet, and the outlet 312. The suction port 311 is connected to a suction pipe assembly to form a suction pipeline, and the drain inlet is connected to a drain outlet 122 to form a drain pipeline. The outlet 312 is connected to the sewer through a drain pipe assembly. This allows the suction pipeline and the drain pipeline to be independent of each other, eliminating the need for a three-way valve and reducing costs. Additionally, each of the suction and drain pipelines has a switch valve to control the on / off state of the pipeline, ensuring that when only one pipeline is working, the other is unaffected. Alternatively, the switch valve on the drain pipeline can be omitted, or both pipelines can be omitted.

[0034] refer to Figure 1-6 The suction pipe assembly includes an inlet pipe 321 and an inlet connector 322. The chassis cover 2 is provided with a fixing part 22 suitable for fixing the inlet connector 322 and located in the water collection chamber 21. The inlet connector 322 is detachably installed on the fixing part 22. One end of the inlet pipe 321 is connected to the suction port 311, and the other end is connected to the water collection chamber 21 through the inlet connector 322. The drain pipe assembly includes a main drain pipe 33. The opposite ends of the main drain pipe 33 are respectively connected to the outlet 312 of the clean drain pump 31 and the sewer.

[0035] Specifically, a plurality of protrusions 23 extending upward and spaced apart are provided in the water collection cavity 21. In this embodiment, there are four protrusions 23, which are paired in pairs to form two pairs of protrusions. The two pairs are respectively located on opposite sides inside the water collection cavity 21. A fixing part 22 is integrally formed on the outer wall of one of the protrusions 23. The fixing part 22 includes two symmetrically arranged fixing buckles 221. The two fixing buckles 221 are configured to jointly clamp the water inlet end of the water inlet connector 322, thereby detachably installing the water inlet connector onto the chassis cover.

[0036] Specifically, an annular groove 3221 is provided on the outer surface of the water inlet end of the water inlet connector 322. In this embodiment, a lower annular flange and an upper annular flange are provided on the outer surface of the water inlet end of the water inlet connector 322 at intervals, and an annular groove 3221 is formed between the upper annular flange and the lower annular flange. When installing the water inlet connector 322, first align the annular groove 3221 of the water inlet connector 322 with the area between the two fixing clips 221, and then push it forcefully between the two fixing clips 221. After installation, the parts of the two fixing clips 221 are respectively inserted into the opposite ends of the annular groove 3221, and the two fixing clips 221 together clamp the water inlet end of the water inlet connector 322 (see Figure 2 This allows the water inlet connector 322 to be stably, reliably, and detachably installed on the chassis cover 2, and prevents the water inlet connector 322 from coming off upwards or downwards.

[0037] refer to Figure 1-7Furthermore, the drainage device also includes a mounting bracket 34 and / or a drainage pump (not shown in the figure). The clean drainage pump 31 is detachably mounted on the water cup assembly 1 via the mounting bracket 34. An installation port 121 and a main drainage outlet 123 are provided on the outer wall of the water cup assembly 1. The main drainage outlet 123 is connected to the water storage chamber 11 through the installation port 121, and the clean drainage outlet 122 is connected to the water storage chamber 11 through the installation port 121. Alternatively, the clean drainage outlet 122 can be directly connected to the water storage chamber 11. The drainage pump is detachably mounted at the installation port 121 and connected to the main drainage outlet 123, used to drain most of the water in the water cup assembly. During the drainage process of the water cup assembly, the drainage pump first automatically drains most of the water in the water cup assembly, and then the clean drainage pump 31 automatically drains the remaining water in the water cup assembly to prevent bacteria growth and odor production due to residual water.

[0038] Specifically, the mounting bracket 34 is snapped onto the upper end of the drain pump 31, and the mounting bracket 34 and the drain pump 31 are detachably connected by at least two first connectors. In this embodiment, first mounting portions 341 are provided on opposite side walls of the mounting bracket 34, and an outwardly extending lug 313 is provided on the outer side wall of the drain pump 31 at a position corresponding to the first mounting portion. The lug 313 is detachably connected to the corresponding first mounting portion 341 by a first connector (e.g., a screw or bolt).

[0039] refer to Figure 7 A locking hole 343 is provided at the top of the mounting bracket 34. The locking hole 343 is T-shaped, with one end larger than the other, and / or a second mounting part 342 is integrally formed on the mounting bracket 34. (Reference) Figure 3 A downwardly extending latching portion 13 is integrally formed at the position corresponding to the latching hole 343 on the water cup assembly 1. The latching portion 13 engages with the latching hole 343 to quickly pre-position the mounting bracket 34 on the water cup assembly. A connecting portion 14 is provided at the position corresponding to the second mounting portion 342 on the water cup assembly 1. The connecting portion 14 and the second mounting portion 342 are detachably connected by a second connector (e.g., screw or bolt) to stably and reliably fix the mounting bracket 34 on the water cup assembly.

[0040] refer to Figure 1-2Furthermore, the drainage system also includes an overflow detection component 4, which is located inside the water collection chamber 21. This component detects whether there is any leakage in the water collection chamber 21 and issues an overflow alarm signal based on the leakage situation. This enables the dishwasher to have a leakage alarm and automatic water removal function. When the dishwasher issues an overflow alarm signal or a high water level signal, the drain pump is activated to promptly remove the water accumulated in the chassis cover 2, effectively reducing the risk of the cabinet being flooded due to leakage. In this embodiment, the overflow detection component 4 includes a float and a micro switch. When the dishwasher leaks, causing the float foam in the chassis cover to rise and trigger the micro switch, the dishwasher issues an overflow alarm signal and a drain pump start command based on the trigger signal. The drain pump can run continuously or intermittently until the micro switch resets as the water level in the chassis cover decreases.

[0041] This embodiment also provides a dishwasher, which includes an inner tub assembly and a drainage system as described above. A water cup assembly 1 is disposed between the inner tub assembly and the base cover 2. The water storage chamber of the water cup assembly 1 is connected to the inside of the inner tub assembly. The water collection chamber 21 of the base cover 2 is connected to the overflow port of the inner tub assembly through an overflow pipe. This enables the timely and automatic discharge of residual water from the water cup assembly and accumulated water on the base cover using the same flush pump, reducing the risk of water leakage causing the cabinet to be soaked, reducing maintenance difficulty and cost, and improving user experience.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
