Description

Technical Field

[0001] This application relates to the field of dishwasher technology, and in particular to a dishwasher flushing device. Background Technology

[0002] Dishwashers, as tools for cleaning dishes, use a large amount of water to rinse the dishes during operation. The rinsed water is then discharged through a drainage system, which includes a water cup, a drain pipe, and a drain pump. Wastewater accumulates in the water cup and is then drained through the drain pipe. However, traditional drain pumps are mostly one-way pumps. When the dishwasher finishes its cycle, some wastewater remains in the pipe between the water cup and the drain pump and flows back into the water cup. Over time, this can lead to bacterial growth in the water cup, potentially affecting human health.

[0003] During the drying process inside the dishwasher, a large amount of steam is generated. This steam is typically released to the outside through a breather. However, due to the narrow exhaust passage of the breather, it cannot expel the steam in time when there is a large amount of steam. If the steam inside the breather cannot be released in time, it will create high pressure in the exhaust passage, which will not only affect the efficiency of subsequent steam discharge but may also damage the breather. Therefore, there is an urgent need for a dishwasher with higher exhaust efficiency. Utility Model Content

[0004] One objective of this application is to provide a dishwasher cleaning and drainage device that can solve at least one of the defects in the aforementioned background art.

[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a dishwasher cleaning and draining device, comprising an inner tub, a water cup, and a peristaltic pump, wherein a breather is installed on the inner tub, the breather is provided with a water storage chamber and a drain chamber, the water storage chamber is provided with a first connector and a second connector, the water cup is provided with a drain port, one end of the peristaltic pump is connected to the first connector, and the other end is connected to the drain port, the second connector is connected to the drain chamber, and the second connector is provided with a first one-way valve for blocking the water flow.

[0006] With this design, when the dishwasher finishes draining, the residual wastewater at the bottom of the cup can be pumped through the drain port into the storage tank for storage, preventing the wastewater from remaining in the cup for a long time and breeding bacteria. When waiting for the next drain, the first one-way valve opens, and the wastewater stored in the storage chamber enters the drain chamber and is discharged together with the wastewater from the previous drain.

[0007] Preferably, the drain outlet is located at the bottom of the water cup, and a stepped groove is provided inside the drain outlet. A removable first filter is installed in the stepped groove, and the size of the first filter is slightly smaller than the size of the stepped groove. This arrangement allows wastewater to be drained from the water cup. The wastewater flows to the peristaltic pump through the gap between the first filter and the stepped groove, while residue in the wastewater is isolated within the water cup, preventing blockage of the drain outlet.

[0008] Preferably, a mutually cooperating limiting structure is provided between the stepped groove and the first filter. This configuration allows the limiting structure to restrict the position of the first filter, preventing its angle from deflecting and affecting the filtration effect.

[0009] Preferably, the water cup is also provided with a wastewater outlet, and there is an arc between the wastewater outlet and the bottom of the water cup. This design allows wastewater generated after dishwasher cleaning to be discharged through the wastewater outlet, while the arc between the wastewater outlet and the bottom of the water cup allows as much water as possible to be discharged through the wastewater outlet.

[0010] Preferably, a removable second filter is installed on the wastewater outlet, and a wastewater inlet is also provided on the drainage chamber, the wastewater inlet being connected to the wastewater outlet. This arrangement prevents residue from the water cup from entering the wastewater outlet and causing blockage, thanks to the second filter.

[0011] Preferably, a second one-way valve is provided on the sewage inlet. With this configuration, when drainage is required, the second one-way valve opens, allowing sewage in the water cup to enter the drainage chamber through the sewage inlet for discharge.

[0012] Preferably, the breather is further provided with an air inlet communicating with the interior of the inner tank. A condenser for condensing steam is installed on the breather, with one end connected to the breather and the other end having an air outlet. The air outlet is connected to the bottom of the dishwasher via a flexible hose and communicates with the outside. With this configuration, steam in the inner tank can enter the breather and condenser sequentially through the air inlet for condensation. The condensed water will then flow back into the inner tank under gravity, making exhaust smoother and improving the drying effect.

[0013] Preferably, the respirator has a first air duct communicating with the air inlet, and the condenser has a second air duct communicating with the first air duct. Condensation fins are installed in both the first and second air ducts. This arrangement allows steam to condense within the first and second air ducts, and the condensation fins increase the contact area with the steam, further improving the machine's condensation efficiency.

[0014] Preferably, a fan is installed inside the condenser. This can further improve the steam flow efficiency and prevent steam from accumulating in the condenser for a long time, thus affecting the subsequent steam discharge.

[0015] Preferably, the top of the water storage chamber extends upwards to form a folded buffer chamber, which is connected to the first air duct. This design allows the buffer chamber to balance the air pressure within the water storage chamber, ensuring that residual wastewater in the water cup can smoothly enter the water storage chamber. Furthermore, it provides a buffer space when the amount of steam in the respirator is large, improving the smoothness of steam discharge.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] Wastewater remaining in the cup is pumped into the storage chamber by a peristaltic pump to prevent it from stagnating at the bottom and breeding bacteria. The storage tank and drain chamber are connected, with a first one-way valve between them. When draining again, the first one-way valve opens and discharges the wastewater in the storage chamber along with the wastewater from the previous drain. Additionally, a second one-way valve is installed at the wastewater inlet of the drain chamber to prevent wastewater from flowing back into the cup and causing water accumulation.

[0018] Steam in the inner liner can enter the breather and condenser sequentially through the air inlet for condensation. The condensed water then flows back into the inner liner under gravity, improving the efficiency of subsequent steam exhaust. Furthermore, the condensing fins installed in the condenser and breather further enhance steam condensation efficiency, making exhaust smoother and thus improving the drying effect. This invention improves the cleanliness of the water cup and has advantages such as strong sewage discharge capacity and high condensation efficiency. Attached Figure Description

[0025] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0029] One aspect of this application provides a dishwasher's flushing device, such as... Figure 1 , Figure 2 and Figure 3As shown, one preferred embodiment includes an inner tank 1, a water cup 4, and a peristaltic pump 100. A breather 2 is installed on the inner tank 1, and the breather 2 has a water storage chamber 21 and a drain chamber 22. The water storage chamber 21 has a first connector 211 and a second connector 212. The water cup 4 has a drain port 41. One end of the peristaltic pump 100 is connected to the first connector 211, and the other end is connected to the drain port 41. When the dishwasher finishes draining, the residual wastewater at the bottom of the water cup 4 can be driven by the peristaltic pump 100 to enter the water storage tank through the drain port 41 for storage, thus preventing the wastewater from remaining in the water cup 4 for a long time and causing bacterial growth that could affect human health.

[0030] Furthermore, such as Figure 2 As shown, the second connector 212 is connected to the drain chamber 22, which has a drain outlet 222 to facilitate the transfer of wastewater from the water storage chamber 21 back into the drain chamber 22 for discharge. Additionally, to prevent water from the water storage chamber 21 from entering the drain chamber 22 during storage, a first one-way valve 201 is installed on the second connector 212. When the dishwasher drains again, the first one-way valve 201 opens, allowing the wastewater stored in the water storage chamber 21 to enter the drain chamber 22 and be discharged along with the wastewater from the previous drain.

[0031] In this embodiment, as Figure 3 and Figure 4 As shown, the drain port 41 is located at the bottom of the water cup 4. A stepped groove 401 is provided inside the drain port 41, and a removable first filter 301 is installed within the stepped groove 401. The size of the first filter 301 is slightly smaller than the size of the stepped groove 401, so that wastewater can flow to the peristaltic pump 100 through the gap between the first filter 301 and the stepped groove 401, while larger particles such as food residue are trapped inside the water cup 4, thus preventing blockage of the drain port 41. Of course, depending on the situation, the first filter assembly can be replaced with components such as a filter screen that also have the ability to isolate residue.

[0032] It is understandable that the position and angle of the first filter 301 may change under the long-term scouring of water. If the position of the first filter 301 is tilted, it will seriously affect the filtering effect of the dishwasher on food residue. Therefore, in some embodiments of this application, a mutually cooperating limiting structure is provided between the stepped groove 401 and the first filter 301. The limiting structure limits the first filter 301 to prevent the angle of the first filter 301 from deflecting and affecting the filtering effect.

[0033] Specifically, such as Figure 4As shown, a limiting groove 401 is provided on the side of the stepped groove 401, and a limiting block 402 is provided on the side of the first filter 301. The user can insert the first filter 301 into the stepped groove 401 and then rotate the first filter 301 to make the limiting block 402 embed into the limiting groove 401, thereby completing the limiting of the first filter 301.

[0034] Furthermore, the water cup 4 is also provided with a wastewater outlet 42, through which the wastewater generated after the dishwasher washes can be discharged; in addition, there is an arc between the wastewater outlet 42 and the bottom of the water cup 4, and the height of the wastewater outlet 42 is slightly lower than the bottom of the water cup 4, so as to ensure that the water in the water cup 4 is discharged through the wastewater outlet 42 as much as possible.

[0035] In this embodiment, as Figure 5 As shown, a detachable second filter 302 is installed in the sewage outlet 42, and a sewage inlet 221 is provided on the drainage chamber 22. The sewage inlet 221 is connected to the sewage outlet 42 to ensure that the sewage in the water cup 4 can enter the drainage chamber 22 for discharge. The second filter 302 prevents the residue in the water cup 4 from entering the sewage outlet 42 and causing blockage. After the drainage is completed, the user can collect and clean the food residue in the water cup 4.

[0036] To prevent water in the drain chamber 22 from flowing back into the water cup 4, such as Figure 2 As shown, a second one-way valve 202 is installed on the sewage inlet 221. When drainage is required, the second one-way valve 202 opens, and the sewage in the water cup 4 can enter the drainage chamber 22 through the sewage inlet 221 for discharge. After the drainage is completed, the second one-way valve 202 closes to block the sewage in the drainage chamber 22, preventing the sewage from flowing back into the water cup 4 and further improving the cleanliness of the water cup 4.

[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the breather 2 is also equipped with an air inlet 23 that communicates with the interior of the inner liner 1. A condenser 3 for condensing steam is installed on the breather 2. One end of the condenser 3 is connected to the breather 2, and the other end has an air outlet 31. The air outlet 31 is connected to the bottom of the dishwasher and communicates with the outside via a hose. Steam in the inner liner 1 can enter the breather 2 and condenser 3 sequentially through the air inlet 23 for condensation. The condensed water will then flow back to the inner liner 1 under gravity, making the exhaust smoother and improving the drying effect.

[0038] Specifically, such as Figure 2As shown, the respirator 2 has a first air duct 24 connected to the air inlet 23, and the condenser 33 has a second air duct 32 connected to the first air duct 24, ensuring that steam in the inner liner 1 can sequentially enter the first air duct 24 and the second air duct 32 for condensation. Furthermore, to further improve the condensation efficiency of the device, condenser plates 300 are provided in both the first air duct 24 and the second air duct 32 to increase the contact area of ​​the steam. When steam flows in the first air duct 24 and the second air duct 32, it collides with the condenser plates 300, then condenses into water, and under the influence of gravity, flows back into the inner liner 1 through the air inlet 23.

[0039] Understandably, in order for the condensate on the condenser 300 to drip down quickly, the condenser 300 in this application should be tilted in the direction of its own gravity. At the same time, a guide plate 26 is provided near the air inlet 23 to guide the condensate into the air inlet 23, so as to ensure that the condensate can quickly enter the inner liner 1.

[0040] Furthermore, such as Figure 2 As shown, a fan 400 is installed inside the condenser 3. The air inlet of the fan 400 is connected to the second air duct 32, and the air outlet of the fan 400 is connected to the air outlet 31. When the fan 400 is running, it can increase the air flow rate, prevent a large amount of steam from accumulating in the breather 2 and the condenser 3, and thus make the exhaust of the dishwasher smoother, thereby improving the drying effect.

[0041] In this embodiment, as Figure 2 As shown, a folded buffer chamber 25 extends upward from the top of the water storage chamber 21, and the buffer chamber 25 is connected to the first air duct 24. The buffer chamber 25 serves two purposes: firstly, it balances the air pressure within the water storage chamber 21, ensuring that residual wastewater in the water cup 4 can smoothly enter the water storage chamber 21; secondly, it provides a buffer space when the amount of steam in the respirator 2 is large, improving the smoothness of steam discharge. When there is a large amount of steam in the first air duct 24, some steam can temporarily enter the buffer chamber 25 for decompression, preventing damage to the respirator 2 due to excessive internal air pressure.

[0042] Furthermore, such as Figure 1 As shown, the top of the buffer chamber 25 is higher than the top of the inner liner 1. This can prevent water in the water storage chamber 21 from splashing into the first air duct 24, and can also prevent steam in the respirator 2 from entering the water storage chamber 21.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.
