Description

Technical Field

[0001] This disclosure relates to the field of kitchen appliance technology, and more particularly to a dishwasher. Background Technology

[0002] Dishwashers are widely used in daily life as kitchen appliances, replacing manual cleaning of dishes and other items. However, if users misuse the dishwasher, such as failing to clean it promptly or leaving it unused for extended periods, residual water inside can breed bacteria and produce unpleasant odors. Therefore, the market demand for dishwashers with no residual water is becoming increasingly strong.

[0003] Furthermore, dishwashers have numerous interconnected internal components. Changing one component will affect the structure of other related components, necessitating a redesign of the molds for these interconnected parts, thus increasing production costs. Therefore, achieving a water-free dishwasher while avoiding increased production costs is a crucial issue that requires attention. Summary of the Invention

[0004] The purpose of this disclosure is to provide a dishwasher that reduces residual water inside the dishwasher and improves the user experience.

[0005] To achieve the above objectives, the embodiments of this disclosure provide the following technical solutions:

[0006] This disclosure provides a dishwasher. The dishwasher includes a washing assembly, a first drain pipe, a drain pump, a breather, a third drain pipe, and a power component. The inlet end of the first drain pipe is connected to the washing assembly. The drain pump is disposed on the first drain pipe. The breather includes a housing, a second drain pipe, an anti-siphon channel, and a first check valve. The second drain pipe is formed inside the housing, the outlet end of the first drain pipe is connected to the inlet end of the second drain pipe, and the outlet end of the second drain pipe is connected to the outside of the housing. The anti-siphon channel is formed inside the housing, the first end of the anti-siphon channel is connected to the second drain pipe, and the second end of the anti-siphon channel is connected to the outside of the housing. The first check valve is disposed on the anti-siphon channel for opening or closing the anti-siphon channel. The inlet end of the third drain pipe is connected to the drain pump, the outlet end of the third drain pipe is connected to the anti-siphon channel, and the first check valve is located between the outlet end of the third drain pipe and the second end of the anti-siphon channel. The power unit is installed on the third drain pipe and is used to drive the residual liquid in the drain pump to flow from the drain pump to the anti-siphon channel.

[0007] The dishwasher provided in this embodiment allows residual water inside the dishwasher to flow into the third drain pipe, which is connected to the drain pump. By installing a power component on the third drain pipe and connecting its outlet end to an anti-siphon channel via a first check valve, the residual water inside the dishwasher can ultimately be discharged to the outside of the dishwasher through the anti-siphon channel and the second drain pipe. This helps reduce residual water inside the dishwasher, keeping it dry, reducing bacterial growth and odors, and improving the user experience. Furthermore, this design avoids directly connecting the outlet end of the third drain pipe to the second drain pipe, thus avoiding the need for openings in the second drain pipe and maintaining its integrity and stability. It also prevents washing water from the second drain pipe from entering the third drain pipe through the anti-siphon channel and damaging the power component due to water pressure.

[0008] In some embodiments, the respirator further includes a receiving cavity formed inside the housing, a second end of the anti-siphon channel communicating with the receiving cavity, the receiving cavity communicating with the outside of the housing, and the outlet end of the third drain pipe communicating with the receiving cavity.

[0009] In some embodiments, the outlet end of the third drain pipe is connected to the top of the receiving cavity, and the second end of the anti-siphon channel is connected to the bottom of the receiving cavity.

[0010] In some embodiments, the respirator further includes a balancing pressure tube and a second check valve. The balancing pressure tube is formed inside the housing, with a first end communicating with the receiving cavity and a second end communicating with the outside of the housing. The second check valve is disposed on the balancing pressure tube and is used to open or close the balancing pressure tube.

[0011] In some embodiments, the dishwasher further includes a receiving container; the third drain pipe includes a first pipe and a second pipe. The inlet end of the first pipe is connected to the drain pump, and the second end of the first pipe is connected to the receiving container. The inlet end of the second pipe is connected to the receiving container, and the outlet end of the second pipe is connected to the anti-siphon channel; the power component is disposed on the second pipe.

[0012] In some embodiments, the washing assembly includes a body and a liquid collection device. The liquid collection device is disposed at the bottom of the body and connected to the body; a water tank is formed on the liquid collection device, the water tank is in communication with the interior of the body, and the inlet end of the first drain pipe is connected to the water tank through the drain pump.

[0013] In some embodiments, the liquid collecting element has a first through hole communicating with the water tank. The drain pump includes a pump casing and a pump body. The pump casing is connected to the liquid collecting element, and a cavity and a liquid collecting port communicating with the cavity are formed on the pump casing. The cavity communicates with the water tank through the first through hole, and the inlet end of the third drain pipe communicates with the liquid collecting port. The pump body is disposed inside the pump casing.

[0014] In some embodiments, the dishwasher further includes a filter screen disposed at the liquid collection port for filtering liquid flowing into the third drain pipe.

[0015] In some embodiments, the collection port is located at or near the bottom of the cavity.

[0016] In some embodiments, the liquid collecting member includes a first portion and a second portion. The water tank is formed on the first portion. The first portion has a second through hole, which corresponds to the drain pump. The second portion is engaged with the second through hole; the first through hole is formed on the second portion.

[0032] The technical solutions in some embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0033] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with this embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0034] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0035] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0036] In addition, the use of “based on” implies openness and inclusivity, because processes, steps, calculations or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0037] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0038] This document describes exemplary embodiments with reference to sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the areas are enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as being limited to the shapes of the areas shown herein, but rather include shape deviations due to, for example, manufacturing processes. For example, etched areas shown as rectangular would typically have curved features. Therefore, the areas shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0039] like Figure 1 As shown, this embodiment of the present disclosure provides a dishwasher 100, which includes a washing assembly 1, a first drain pipe 2, and a drain pump 3. The water inlet end of the first drain pipe 2 is connected to the washing assembly 1, and the drain pump 3 is disposed on the first drain pipe 2.

[0040] For example, such as Figure 1 As shown, the washing assembly 1 may include a circulation pump 11, a water inlet pipe 12, a spray arm 13, and a shelf 14. The circulation pump 11 is connected to the water inlet pipe 12, and the water inlet pipe 12 is connected to the spray arm 13. The spray arm 13 is provided with a plurality of spray holes connected to the water inlet pipe 12.

[0041] When the dishwasher 100 is required to perform a washing operation, the dishes to be washed are placed on the rack 14. Washing water is introduced into the dishwasher 100. The washing water enters the circulation pump 11 through a connecting pipe connected to the circulation pump 11. The circulation pump 11 starts, thereby delivering the washing water to the water inlet pipe 12, and finally to the spray arm 13 along the water inlet pipe 12. The washing water is sprayed out from the spray holes on the spray arm 13 to wash the dishes placed on the rack 14. Afterwards, the washing water continues to flow back to the circulation pump 11, forming a circulating washing process. The water flow direction in the circulation pump 11 and the water inlet pipe 12 can be referenced as follows: Figure 2 The dotted line ① in the text.

[0042] For example, the number of spray arms 13 can be one or more. Figure 1 Taking three spray arms 13 as an example, the spray arms 13 include the top spray arm 13A, the middle spray arm 13B, and the bottom spray arm 13C.

[0043] Understandably, the more spray arms 13 there are, the more spray holes on the spray arms 13 will be, and more water will be used to clean the dishes placed on the shelf 14, which will help improve the washing ability and washing efficiency of the dishwasher 100.

[0044] For example, the number of shelves 14 can be one or more. Figure 1 Taking two shelves 14 as an example, the shelves 14 include the top shelf 14A and the bottom shelf 14B.

[0045] For example, the upper shelf 14A is disposed between the top spray arm 13A and the middle spray arm 13B, and the lower shelf 14B is disposed between the middle spray arm 13B and the bottom spray arm 13C.

[0046] Understandably, the more shelves 14 there are, the more dishes can be placed, thus increasing the number of dishes that the dishwasher 100 can wash in a single cycle. Furthermore, by placing the shelves between two shelves 14, the washing water sprayed from the spray nozzles of the two spray arms 13 can simultaneously wash the dishes on the shelves 14, thereby improving the washing capacity of the dishes on the shelves 14.

[0047] In some examples, such as Figure 1 As shown, the washing assembly 1 also includes a body 15 and a liquid collection device 16. The liquid collection device 16 is located at the bottom of the body 15 and is connected to the body 15. A water tank S is formed on the liquid collection device 16, and the water tank S is connected to the interior of the washing assembly 1. The water inlet end of the first drain pipe 2 is connected to the water tank S through a drain pump 3.

[0048] For example, the body 15 is the inner tub of the dishwasher 100, which forms a washing space to accommodate the spray arm 13, the shelf 14, and tableware, etc.

[0049] For example, the liquid collection unit 16 is detachably connected to the body 15.

[0050] For example, the liquid collection component 16 is connected to the body 15 by threads, and a rubber ring is provided between the liquid collection component 16 and the body 15 for sealing. This makes it easy to disassemble the liquid collection component 16 and prevents water leakage at the connection between the liquid collection component 16 and the body 15.

[0051] For example, a filter device is provided at the connection position between the liquid collection component 16 and the body 15, which can filter the washing water flowing into the liquid collection component 16 to prevent food residue from entering the circulation pump 11 (and the drain pump 3 and the power component mentioned below) and causing damage to the circulation pump 11 (and the drain pump 3 and the power component mentioned below).

[0052] For example, the above-mentioned filtration device and liquid collection element 16 can be an integral structure.

[0053] This reduces the number of parts in the dishwasher 100, which helps simplify the assembly process.

[0054] Alternatively, the aforementioned filter device may be a separate component, mounted on the liquid collection member 16 by fasteners. For example, the filter device may be mounted on the liquid collection member 16 by screws.

[0055] This allows for flexible disassembly of the aforementioned filter device, facilitating its cleaning and replacement.

[0056] For example, such as Figure 1 As shown, the water tank S formed on the liquid collection member 16 is used to collect the washing water sprayed from the spray holes of the spray arm 13.

[0057] For example, such as Figure 1 and Figure 2 As shown, the inlet of the circulation pump 11 is connected to the water tank S, so that the washing water collected by the water tank S and sprayed from the spray holes of the spray arm 13 can enter the circulation pump 11 to form a circulating washing process.

[0058] For example, the drain pump 3 is located at or near the lowest point of the liquid collection unit 16, which facilitates the drainage of washing water from the liquid collection unit 16.

[0059] For example, the type of drainage pump 3 can be a centrifugal pump or an axial flow pump, etc.

[0060] See Figure 2 After the washing unit 1 of the dishwasher 100 has finished its operation, the washing water inside the dishwasher 100 needs to be drained. The drain pump 3 is used to direct the washing water inside the dishwasher 100 to the first drain pipe 2 and discharge it. The water flow direction in the drain pump 3 and the first drain pipe 2 can be referenced... Figure 2 The dotted line ② in the text.

[0061] In some examples, such as Figure 1 As shown, the dishwasher 100 also includes a breather 4, which includes: a housing 41, a second drain pipe 42, an anti-siphon channel 43, and a first check valve 44. The second drain pipe 42 is formed inside the housing 41, with the outlet end of the first drain pipe 2 connected to the inlet end of the second drain pipe 42, and the outlet end of the second drain pipe 42 connected to the outside of the housing 41. The anti-siphon channel 43 is formed inside the housing 41, with its first end connected to the second drain pipe 42 and its second end connected to the outside of the housing 41. The first check valve 44 is disposed on the anti-siphon channel 43 and is used to open or close the anti-siphon channel 43.

[0062] For example, housing 41 is used to protect internal components.

[0063] For example, such as Figure 1 As shown, the second drain pipe 42 is inverted U-shaped, which can increase the liquid level in the second drain pipe 42 and achieve the effect of preventing siphoning.

[0064] By providing a second drain pipe 42, the washing water in the first drain pipe 2 can be discharged to the outside of the outer casing 41 through the second drain pipe 42.

[0065] For example, the anti-siphon channel 43 is connected to the outside, which can balance the air pressure between the anti-siphon channel 43 and the outside, and can prevent the siphon phenomenon from occurring in the first drain pipe 2 during the process of the dishwasher 100 discharging washing water, prevent the clean washing water in the liquid collection component 16 from being discharged, and prevent the heating component in the dishwasher 100 from burning dry.

[0066] For example, the first check valve 44 can be unidirectionally open, allowing external air to enter the anti-siphon channel 43 through the first check valve 44 to balance the air pressure between the anti-siphon channel 43 and the outside. It can also prevent the washing water in the second drain pipe 42 from flowing out of the anti-siphon channel 43 to the outside due to excessive water pressure during the operation of the drain pump 3.

[0067] In related technologies, dishwashers stop working after draining the washing water. However, residual water remains on the washing components, washed dishes, and the inner walls of the machine. Over time, this residual water can promote bacterial growth and produce odors, affecting the user experience.

[0068] Based on this, the dishwasher 100 of this embodiment further includes a third drain pipe 5 and a power component 6. The inlet end of the third drain pipe 5 is connected to the drain pump 3, and the outlet end of the third drain pipe 5 is connected to the anti-siphon channel 43. The first check valve 44 is located between the outlet end of the third drain pipe 5 and the second end of the anti-siphon channel 43. The power component 6 is disposed on the third drain pipe 5 and is used to drive the residual liquid in the drain pump 3 to flow from the drain pump 3 to the anti-siphon channel 43.

[0069] For example, the power component 6 can be a water pump.

[0070] like Figure 1 As shown, by setting up the third drain pipe 5, residual water present in the washing components 1, washed dishes, and the inner wall of the machine body 15 inside the dishwasher 100 will collect in the collection unit 16, and then flow into the third drain pipe 5 through the drain pump 3. After the power unit 6 on the third drain pipe 5 is activated, the residual water flowing into the third drain pipe 5 can flow through the first check valve 44 to the anti-siphon channel 43 due to water pressure, and then flow into the second drain pipe 42 to the outside, thereby draining the residual water from the dishwasher 100. This helps to keep the inside of the dishwasher 100 dry, reduce bacterial growth and odors, and improve the user experience of the dishwasher 100. Figure 1 As shown, the direction of the residual water drain from the dishwasher 100 can be referenced. Figure 1 The dotted line ③ in the text.

[0071] Furthermore, by connecting the outlet end of the third drain pipe 5 to the anti-siphon channel 43, it is possible to avoid directly connecting the outlet end of the third drain pipe 5 to the second drain pipe 42, thereby avoiding the need for drilling holes in the second drain pipe 42 and helping to maintain the integrity and stability of the second drain pipe 42. In addition, a first check valve 44 is also installed between the outlet end of the third drain pipe 5 and the anti-siphon channel 43, which can prevent washing water in the second drain pipe 42 from entering the third drain pipe 5 through the anti-siphon channel 43 and damaging the power component 6 due to the water pressure of the washing water.

[0072] Therefore, the dishwasher 100 provided in this embodiment of the present disclosure, by providing a third drain pipe 5 connected to the drain pump 3, allows residual water inside the dishwasher 100 to flow into the third drain pipe 5. By providing a power component 6 on the third drain pipe 5 and connecting the outlet end of the third drain pipe 5 to the anti-siphon channel 43 through the first check valve 44, the residual water inside the dishwasher 100 can ultimately be discharged to the outside of the dishwasher 100 through the anti-siphon channel 43 and the second drain pipe 42. This helps reduce residual water inside the dishwasher 100, keeps the inside of the dishwasher 100 dry, reduces bacterial growth and odors, and improves the user experience of the dishwasher 100. Furthermore, the above arrangement also avoids directly connecting the outlet end of the third drain pipe 5 to the second drain pipe 42, thereby avoiding the need for opening holes in the second drain pipe 42, which helps maintain the integrity and strength of the second drain pipe 42; it also prevents washing water in the second drain pipe 42 from entering the third drain pipe 5 through the anti-siphon channel 43 and damaging the power component 6 due to the water pressure of the washing water.

[0073] In addition, the dishwasher 100 provided in this embodiment does not require major modifications to other internal functional components, thus avoiding the need to redesign the molds of other interrelated functional components and avoiding increasing the production cost of the dishwasher.

[0074] In some examples, the aforementioned power component 6 can be a positive displacement pump, such as a diaphragm pump, gear pump, piston pump, peristaltic pump, etc. This prevents backflow of liquid in the third drain pipe 5.

[0075] In some examples, the collection unit 16 is also provided with a water inlet valve for introducing clean washing water into the dishwasher 100.

[0076] In some examples, the liquid collection unit 16 is also provided with a heating element, which is used to heat the washing water. The heated washing water can improve the washing ability of the dishes to be washed and improve the washing efficiency.

[0077] In some examples, the liquid collection unit 16 is also provided with a pressure sensor and an air chamber for connecting the pressure sensor. The pressure sensor can detect the pressure of the washing water, so as to determine the height of the washing water level in the dishwasher 100 based on the pressure of the washing water.

[0078] In some examples, the liquid collection unit 16 is also equipped with a temperature sensor, which can detect and obtain the temperature of the washing water, thereby determining whether the washing water needs to be heated.

[0079] In some examples, the collection unit 16 is also equipped with a turbidity sensor, which can detect and obtain the turbidity of the washing water, so as to determine whether the washing water needs to be replaced.

[0080] In some examples, the dishwasher 100 also includes a drying unit for drying the components inside the dishwasher 100, which helps to maintain a dry environment inside the dishwasher 100.

[0081] In some examples, the dishwasher 100 also includes a processor that determines the state of the dishwasher 100 based on the aforementioned sensors and sends control signals to various components (such as the circulation pump).

[0082] In some embodiments, such as Figure 3 As shown, the respirator 4 also includes a receiving cavity 45 formed inside the outer shell 41, the second end of the anti-siphon channel 43 is connected to the receiving cavity 45, the receiving cavity 45 is connected to the outside of the outer shell 41, and the water outlet end of the third drain pipe 5 is connected to the receiving cavity 45.

[0083] For example, the receiving cavity 45 is used to receive residual water flowing in from the outlet end of the third drain pipe 5.

[0084] By setting up the receiving cavity 45, space can be provided for the residual water, which can prevent the residual water in the third drain pipe 5 from being discharged in a timely manner due to the small flow rate of the anti-siphon channel 43 or the first check valve 44, and helps to reduce the workload of the power component 6.

[0085] In some embodiments, such as Figure 3 As shown, the outlet end of the third drain pipe 5 is connected to the top of the receiving cavity 45, and the second end of the anti-siphon channel 43 is connected to the bottom of the receiving cavity 45.

[0086] For example, the top of the receiving cavity 45 is provided with a connector to facilitate the connection between the outlet end of the third drain pipe 5 and the receiving cavity 45.

[0087] With the above settings, the residual water in the receiving cavity 45 can open the first check valve 44 by its own gravity, and the residual water in the receiving cavity 45 can flow out to the outside of the dishwasher 100 through the anti-siphon channel 43.

[0088] In some embodiments, such as Figure 3 As shown, the respirator 4 also includes a balancing pressure tube 46 and a second check valve 47. The balancing pressure tube 46 is formed inside the housing 41, with its first end connected to the receiving cavity 45 and its second end connected to the outside of the housing 41. The second check valve 47 is disposed on the balancing pressure tube 46 and is used to open or close the balancing pressure tube 46.

[0089] For example, the second check valve 47 can allow air in the balancing air pipe 46 to flow unidirectionally into the receiving cavity 45, thereby balancing the air pressure in the receiving cavity 45 and the balancing air pipe 46, that is, balancing the air pressure in the receiving cavity 45 and the outside air.

[0090] With the above settings, the residual water in the receiving cavity 45 can flow out to the outside through the anti-siphon channel 43 and the second drain pipe 42, and avoid excessive residual water in the receiving cavity 45 from flowing out through the balance air pressure pipe 46.

[0091] In some embodiments, such as Figure 3 As shown, the dishwasher 100 also includes a receiving container 7. The third drain pipe 5 includes a first pipe 51 and a second pipe 52. The inlet end of the first pipe 51 is connected to the drain pump 3, and the second end of the first pipe 51 is connected to the receiving container 7. The inlet end of the second pipe 52 is connected to the receiving container 7, and the outlet end of the second pipe 52 is connected to the anti-siphon channel 43. The power unit 6 is disposed on the second pipe 52.

[0092] For example, such as Figure 4 As shown, the container 7 has an inlet 71 and an outlet 72. The inlet 71 is located at the upper part of the container 7, and the outlet 72 is located at the lower part of the container 7, which facilitates the flow of liquid from the inlet 71 and the flow of liquid from the outlet 72.

[0093] For example, the second end of the first pipe 51 is connected to the water inlet 71 of the container 7, and the water inlet of the second pipe 52 is connected to the water outlet 72 of the container 7.

[0094] For example, such as Figure 5 As shown, the power component 6 has an inlet 61 and an outlet 62, which are respectively connected to the second pipe 52.

[0095] During the operation of the power unit 6, the liquid can be driven to flow in the direction from inlet 61 to outlet 62.

[0096] With the above settings, as much residual water as possible can be drained from the container 7, allowing it to flow into the anti-siphon channel 43, thereby reducing the amount of residual water in the container 7 and helping to keep the inside of the dishwasher 100 dry.

[0097] In some embodiments, combined with Figures 6-9 The liquid collecting component 16 has a first through hole K1 that communicates with the water tank S. Combined with... Figures 10-13The drainage pump 3 includes a pump casing 31 and a pump body 32. The pump casing 31 is connected to the liquid collecting member 16, and a cavity Q and a liquid collecting port 311 communicating with the cavity Q are formed on the pump casing 31. The cavity Q is connected to the water tank S through a first through hole K1, and the water inlet end of the third drain pipe 5 is connected to the liquid collecting port 311. The pump body 32 is disposed inside the pump casing 31.

[0098] For example, the washing water in the water tank S enters the cavity Q through the first through hole K1, and is discharged to the first drain pipe 2 by the drain pump 3.

[0099] For example, such as Figure 12 and Figure 13 As shown, the liquid collecting component 16 includes a protruding portion 161 corresponding to the drain pump 3, and the protruding portion 161 of the liquid collecting component 16 and the pump housing 31 together form a cavity Q.

[0100] For example, the pump housing 31 is detachably connected to the protrusion 161 of the liquid collection member 16.

[0101] For example, the pump housing 31 and the protruding part 161 are connected by a snap-fit, which makes it convenient to inspect and replace the drainage pump 3.

[0102] Understandably, the blades of the drainage pump 3 are located inside the cavity Q.

[0103] For example, the pump casing 31 is also provided with an exhaust port (not shown in the figure), through which air in the cavity Q can be discharged, which is beneficial to the normal operation of the drainage pump 3.

[0104] In some examples, such as Figure 10 As shown, the liquid collection port 311 is located at or near the bottom of the cavity Q.

[0105] This design allows residual water in the dishwasher 100 to collect in the sink S, enter the cavity Q through the first through hole K1 connected to the sink S, and then enter the third drain pipe 5 connected to the collection port 311. This facilitates the power unit 6 to discharge the residual water through the third drain pipe 5, thus keeping the inside of the dishwasher 100 dry.

[0106] For example, the pump body 32 is the driving component of the drainage pump 3.

[0107] For example, pump body 32 includes a motor.

[0108] In some embodiments, such as Figure 10 As shown, the dishwasher 100 also includes a filter screen 8, which is located at the liquid collection port 311 and is used to filter the liquid flowing into the third drain pipe 5.

[0109] For example, the filter screen 8 is detachably connected to the pump housing 31.

[0110] This setup makes it easy to clean and replace filter 8.

[0111] By setting up a filter screen 8, impurities can be prevented from entering the third drain pipe 5 through the liquid collection port 311, thus avoiding damage to the power component 6 installed on the third drain pipe 5.

[0112] In some embodiments, combined with Figures 6-9 The liquid collecting component 16 includes a first portion 162 and a second portion 163. A water tank S is formed on the first portion 162. The first portion 162 has a second through hole K2, which is correspondingly disposed with respect to the drain pump 3. The second portion 163 is engaged with the second through hole K2. A first through hole K1 is formed on the second portion 163.

[0113] For example, the first part 162 and the second part 163 are connected by a snap-fit.

[0114] Understandably, in combination Figure 13 After removing the second part 163, the blades of the drain pump 3 can be exposed. If the drain pump 3 is blocked by foreign objects, the second part 163 can be opened to remove the foreign objects from the drain pump 3.

[0115] The above settings can reduce the maintenance difficulty of drainage pump 3.

[0116] like Figure 14 As shown in the embodiments of this disclosure, a control method for a dishwasher is also provided. After the dishwasher is turned on, the dishwasher starts its program and controls the drain pump to drain water to avoid residual washing water inside the dishwasher. Then, the processor controls the water inlet valve to open, allowing water to enter the dishwasher. The processor determines whether the heating element needs to be activated according to the program settings. If heating is not required, the processor controls the circulation pump to operate, and the dishwasher begins washing; if heating is required, the processor controls the circulation pump to operate, the dishwasher begins washing, and simultaneously controls the heating element to operate, heating the washing water. After a period of time, the washing cycle ends, and the drain pump discharges the washing water. The processor then determines whether it is the final washing stage. If the determination result is "no," the above-mentioned "water inlet valve opens, dishwasher fills with water" step continues; if the determination result is "yes," the washing cycle ends, and the drain pump discharges the washing water. Then, the power unit is activated to discharge residual water. After the residual water is discharged, the drying stage begins. The processor controls the drying unit to operate, and then the power unit is activated again to discharge residual water, and the program ends.

[0117] Therefore, the dishwasher control method provided in this embodiment includes at least one process of power component discharge of residual water after the drain pump discharges the washing water. Thus, the residual water inside the dishwasher can be discharged, keeping the inside of the dishwasher dry, avoiding the generation of odors, and improving the user experience of the dishwasher.

[0118] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
