The invention provides a drainage structure, a dish washer base and a dish washer, wherein a water outlet pipe 3 extends outwards from the side wall of a drainage pump installation cavity 2 in an inclined mode, an included angle between the side wall of the drainage pump installation cavity 2 and the central line of the water outlet pipe 3 is set to be 2-8 degrees, smoothness of water flow is improved, drainage amount of a drainage pump in a certain time can reach the maximum value, and further efficiency of the drainage pump is improved.

Referring to fig. 1 to 4, the drain outlet structure is used for discharging water in a dishwasher base 1, and comprises a drain pump installation cavity 2 and a water outlet pipe 3 communicated with the drain pump installation cavity 2, wherein the water outlet pipe 3 extends outwards in an inclined manner from the side wall of the drain pump installation cavity 2; the included angle between the side wall of the drainage pump installation cavity 2 and the central line of the water outlet pipe 3 is set to be 2-8 degrees.

According to the drainage structure provided by the embodiment of the invention, the water outlet pipe 3 is outwards and obliquely extended from the side wall of the drainage pump installation cavity 2, and the included angle between the side wall of the drainage pump installation cavity 2 and the central line of the water outlet pipe 3 is set to be 2-8 degrees, so that under the condition that the diameter of the water outlet pipe 3 is fixed, smooth drainage of water flow from the water outlet pipe 3 is facilitated, the smoothness of water flow is improved, the drainage amount of the drainage pump in a certain time can reach the maximum value, the efficiency of the drainage pump reaches the highest utilization, and the efficiency of the drainage pump is improved.

In the prior art, the center line of the water outlet pipe 3 is perpendicular to the sidewall of the installation cavity of the drain pump, so that the diameter requirement on the water outlet pipe 3 is larger, and the space utilization rate of the base 1 is lower. In particular, it is a common practice for those skilled in the art to increase the diameter of the water outlet pipe 3 in order to smoothly discharge the water flow, and thus the diameter of the water outlet pipe 3 is generally set to 20mm or more, thus also making the space utilization low. In addition, in the case where the diameter of the water outlet pipe 3 is constant, when the angle between the sidewall of the drain pump installation chamber 2 and the center line of the water outlet pipe 3 is set to be less than 2 degrees or more than 8 degrees, the amount of water discharged by the drain pump is reduced for the same drain pump for a certain period of time. In detail, the invention sets the included angle between the side wall of the drainage pump installation cavity 2 and the central line of the water outlet pipe 3 to be any one of 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees or 8 degrees. In the embodiment of the invention, the water discharge pump is preferably set to be 5 degrees, so that the water discharge amount of the water discharge pump can reach the maximum value in a certain time aiming at the same water discharge pump, and the efficiency of the water discharge pump reaches the highest utilization.

In addition, referring to fig. 1, x indicates the length of the water pipe 3; referring to fig. 2, c refers to an included angle between a sidewall of the drain pump installation cavity 2 and a center line of the water outlet pipe 3; referring to fig. 3, d refers to an angle between the center line of the guide vane 4 and the center line of the water outlet pipe 3; referring to fig. 4, e indicates the diameter of the water pipe 3.

Preferably, the diameter of the water outlet pipe 3 is set to be 12-15 mm. It should be noted that, because the larger the included angle C between the side wall of the drain pump installation cavity 2 and the center line of the water outlet pipe 3 is, the larger the diameter E of the water outlet pipe 3 is required, therefore, by setting the included angle between the side wall of the drain pump installation cavity 2 and the center line of the water outlet pipe 3 to 2-8 °, the diameter of the water outlet pipe 3 can be further set to 12-15 mm, thereby increasing the space utilization rate of the base 1 and simultaneously ensuring that the efficiency of the drain pump reaches the highest. In detail, the diameter of the water outlet pipe 3 is set to be any one of 12mm, 13mm, 14mm or 15mm, so that the space utilization rate of the base 1 is ensured to be high.

Preferably, the side wall of the drainage pump installation cavity 2 is provided with a water outlet communicated with the water outlet pipe 3, and the periphery of the water outlet is provided with a guide vane 4 for guiding out water flow in the drainage pump installation cavity 2. The guide vane 4 arranged at the periphery of the water outlet is used for guiding out the water flow in the drainage pump installation cavity 2, so that the smoothness of the water flow is improved. In addition, a diversion trench can be arranged in the drainage pump installation cavity 2, so that the water flow is further conveniently led into the water outlet pipe 3, and the water is smoothly discharged.

Preferably, the guide vane 4 is arranged at an angle to the outlet pipe 3. In a refinement, the included angle D between the central line of the guide vane 4 and the central line of the water outlet pipe 3 is 30-60 degrees. It should be noted that, if the included angle between the center line of the deflector 4 and the center line of the water outlet pipe 3 is smaller than 30 degrees or larger than 60 degrees, the water flow will react with the deflector 4 during the discharging process, the deflector 4 will block the water flow, and the water flow will not be smoothly discharged from the water outlet pipe 3. Therefore, the angle D between the center line of the deflector 4 and the center line of the outlet pipe 3 is preferably 30 to 60 °. In this embodiment, the guide vane 4 and the drain pump installation cavity 2 are integrally formed, and the guide vane 4 can be set as two walls of the drain pump installation cavity 2, so that the overall performance of the connection between the guide vane 4 and the drain pump installation cavity 2 is increased. In addition, the guide vane 4 can be manufactured into an independent mounting vane, so that the installation and the replacement are convenient. Specifically, the included angle D between the center line of the deflector 4 and the center line of the outlet pipe 3 is set to any one of 30 °, 40 °, 50 ° or 60 °.

Preferably, the number of the guide vanes 4 may be plural, and the plurality of guide vanes 4 may be divided into two groups symmetrical with respect to the center line of the water outlet pipe 3. Through a plurality of guide vanes 4, the water flow is further helped to be smoothly guided out of the water outlet pipe 3, and the smoothness of the water flow is further improved.

Preferably, the length X of the water outlet pipe 3 is set to 20 to 35mm, so that the assembly is convenient while the installation space of the base 1 is effectively utilized. Preferably, the length of the water outlet pipe 3 can be set to any one of 20mm, 25mm, 30mm or 35mm according to actual needs, so as to facilitate assembly and use.

In addition, the invention also provides a dish washer base 1, which comprises the water draining and discharging structure.

The invention also provides a dish washer which comprises the water draining and discharging structure.

It should be noted that, because the dish washer base 1 and the dish washer can both relate to the drainage water outlet structure, the water flow is smoothly discharged from the water outlet pipe 3 through the arrangement of the drainage water outlet structure, the smoothness of the water flow is increased, and the drainage amount of the drainage pump in a certain time can reach the maximum value, so that the efficiency of the drainage pump is improved.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
