Description

TECHNICAL FIELD

[0001] The utility model relates to a dish-washing machine, and particularly provides a dish-washing machine water cup assembly and dish-washing machine. BACKGROUND

[0002] The inner container of the dish-washing machine is usually provided with a water cup structure, which is provided with a water outlet and connected to the water inlet end of a circulating water pump through a pipeline. The water outlet end of the circulating water pump is connected to a spray arm, thereby forming a complete water circulation system. During the operation of the dish-washing machine, the circulating water pump draws the washing water in the water cup and delivers it to the spray arm to perform high-pressure spray cleaning on tableware, thereby ensuring the effective removal of stains. The stability of the water circulation system directly affects the cleaning efficiency and working reliability of the dish-washing machine.

[0003] However, in actual use, when the water level in the water cup is low, a funnel-shaped vortex will be generated near the water outlet, which will cause some air to enter the water outlet and then enter the water pump. This air suction phenomenon will cause cavitation in the water pump, which is specifically manifested as follows: when the local pressure at the impeller of the water pump drops below the saturated vapor pressure of the washing water, a large number of air bubbles will be formed in the liquid. These air bubbles will rapidly break and generate shock waves after entering the high-pressure zone, causing continuous mechanical damage to the impeller and other flow components, thereby affecting the normal operation of the water pump. The cavitation phenomenon not only reduces the working efficiency of the water pump, but also causes abnormal noise and severe vibration during the operation of the equipment, which seriously affects the service life and overall operation reliability of the water pump. In addition, the mixing of air will also significantly reduce the water pressure of the spray system, causing the water discharge amount and spraying force of the spray arm to decrease, thereby affecting the washing effect of the tableware and causing incomplete cleaning.

[0004] Therefore, there is an urgent need in the art for a dish-washing machine water cup assembly and dish-washing machine to solve the above problems. SUMMARY

[0040] To solve the problem that the water pump of the existing dishwasher is easy to suck in air at the water outlet of the water cup, the embodiment discloses a dishwasher to optimize the structure of the water cup, reduce the entry of air, and improve the service life of the water pump. The dishwasher comprises a water cup assembly and a water pump. Referring to Figure 1 , the water cup assembly comprises a water cup 1 and a baffle 2. The water cup 1 is arranged at the bottom of the inner tank of the dishwasher. The water cup 1 is provided with a downwardly recessed groove 101 for accommodating water inside the dishwasher. The side wall of the groove 101 is provided with a water outlet 102 connected to the water inlet of the water pump. The water pump can drive the water in the water cup 1 to enter the water pump through the water outlet 102 and deliver it to the spray arm to complete the spray cleaning process of the tableware. Referring to Figure 2 , the baffle 2 is arranged in front of the water outlet 102 to limit the water level flowing into the water outlet 102 and prevent air from mixing due to the reduction of water quantity. Specifically, one end of the baffle 2 is arranged at the inner wall of the groove 101 above the water outlet 102, and the other end extends to the lower part of the groove 101, so that the bottom of the baffle 2 is lower than the top of the water outlet 102. This arrangement can reduce the water level flowing into the water outlet 102, so that when the water quantity in the groove 101 is small, air can still be prevented from entering the water outlet 102, reducing the risk of cavitation of the water pump.

[0041] Further, the bottom of the water outlet 102 is provided with a slope surface 1021, and the part close to the water cup 1 is higher than the part away from the water cup 1. The slope surface 1021 and the baffle 2 form a horn structure, and specifically, the cross-sectional area of the part close to the water cup 1 is smaller than that of the part away from the water cup 1. This arrangement can deepen the water level flowing into the water outlet 102, thereby avoiding the entry of air into the water outlet 102 when the water level in the water cup 1 is low.

[0042] The specific arrangement of the baffle 2 will be described below through two embodiments.

[0043] Embodiment one

[0044] Referring to Figure 3 and Figure 4The water cup assembly further comprises a filter 3 for filtering impurities in water flowing into the water cup 1. The filter 3 comprises a support 301 and a filter screen, which is not shown in the figure. The number of supports 301 is four, and the four supports 301 are arranged at intervals along the circumference. An installation portion 3011 is formed at the interval between the two adjacent supports 301, and the filter screen is arranged in the installation portion 3011. The baffle 2 is in the shape of an annular plate, and the baffle 2 is sleeved outside the filter 3. The inner side edge of the baffle 2 is connected with the four supports 301. The baffle 2 is arranged on the filter 3, so that the baffle 2 can be installed synchronously during the installation of the filter 3, and the assembly operation of the baffle 2 does not need to be performed separately. This structure optimizes the assembly process, reduces the independent installation steps of the parts, helps to reduce the production cost and improve the assembly efficiency. Further, the inner side edge of the baffle 2 is provided with a containing groove 201 for containing the filter screen. This arrangement makes the close fit of the outer side edge of the baffle 2 with the inner wall of the groove 101 of the water cup 1 effectively reduce the existence of the gap, avoid the air leakage problem caused by the gap, and thus reduce the possibility of air entering the water outlet 102.

[0045] With reference to Figure 1 and Figure 2 , the filter 3 is at least partially arranged in the groove 101 of the water cup 1, so that the baffle 2 is arranged in the groove 101. The groove 101 is in the shape of a cylindrical recess, and an annular interval is formed between the inner wall of the groove 101 and the outer wall of the filter 3. The inner side edge of the baffle 2 is fitted to the outer wall of the filter 3, and the outer side edge is fitted to the inner wall of the groove 101, so that the baffle 2 closes the gap between the groove 101 and the filter 3, preventing air from entering the water outlet 102. The inner side edge of the baffle 2 is lower than the outer side edge, and the outer side edge of the baffle 2 is higher than the top of the water outlet 102, and the inner side edge is lower than the top of the water outlet 102. This arrangement can reduce the water level entering the water outlet 102 and reduce the air intake of the water pump. Further, the inclination angle of the part of the baffle 2 close to the water outlet 102 relative to the horizontal plane is greater than the inclination angle of the part of the baffle 2 away from the water outlet 102 relative to the horizontal plane.

[0046] Regarding the groove 101 and the filter 3, although the shape of the groove 101 in the embodiment is a cylindrical recess, and an annular interval is formed between the inner wall of the groove 101 and the outer wall of the filter 3, this arrangement is not a limitation of the utility model, and those skilled in the art can also use other arrangements in other embodiments without deviating from the principles of the utility model, for example: the shape of the groove 101 can adopt other geometric structures, such as polygons or ellipses, or the interval between the groove 101 and the filter 3 can be changed to adapt to different installation requirements or optimize the water flow path. This does not deviate from the basic principles of the utility model, and therefore falls within the scope of protection of the utility model.

[0047] Further, referring to Figure 5 , one of the inner wall of the groove 101 and the outer side edge of the baffle 2 is provided with a recess, and the other is provided with a corresponding protrusion. The shape of the recess matches the shape of the protrusion, so that the baffle 2 and the groove 101 are kept in close contact. The setting mode of the shape-matched recess and protrusion 4 can make the groove 101 and the baffle 2 fit more closely, prevent air leakage; It can also prevent the filter 3 from rotating in the groove 101, and ensure its stability after installation.

[0048] Example two

[0049] Referring to Figure 6 and Figure 7 , the baffle 2 is integrally formed with the water cup 1. The baffle 2 extends from the upper side of the water outlet 102 to the lower side of the front side of the water outlet 102, so that the bottom of the baffle 2 is lower than the top of the water outlet 102. This setting mode can reduce the water level entering the water outlet 102 and reduce the air intake of the water pump. This setting mode can also avoid installing the baffle 2 separately, and simplify the assembly process. This setting mode effectively avoids the complex operation of separately installing the baffle 2 in the traditional way, thereby simplifying the assembly process and reducing the assembly time and labor cost of the assembly.

[0050] Further, the baffle 2 and the inner wall of the groove 101 of the water cup 1 are provided with a reinforcing rib to improve the structural strength of the baffle 2. Further, the baffle 2 and the inner wall of the groove 101 of the water cup 1 are provided with a plurality of reinforcing ribs, and the plurality of reinforcing ribs are arranged along the edge of the baffle 2.

[0051] Further, the bottom of the water outlet 102 is provided with a slope 1021, and the slope 1021 and the baffle 2 form a horn. The cross-sectional shape of the part of the horn close to the water cup 1 is approximately rectangular or waist-shaped hole, and the cross-sectional shape of the part of the horn away from the water cup 1 is approximately circular. This setting mode can deepen the water level flowing into the water outlet 102, thereby avoiding air entering the water outlet 102 when the water level in the water cup 1 is low.

[0052] So far, the technical scheme of the present application has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without deviating from the principles of the present application, those skilled in the art can make equivalent changes or replacements to related technical features, and the technical scheme after these changes or replacements will fall within the protection scope of the present application.
