For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0038] Based on the background technology pointing out that the existing dishwashers have a residual drainage problem, the utility model provides a dishwasher, which aims to connect the sink and the first drainage pipe by setting a second drainage pipe and a connecting pipe, and then after the second drainage pipe is connected to the water source, when the water flows through the connection between the second drainage pipe and the connecting pipe, the flow rate increases and the pressure decreases, thereby forming a negative pressure at the connection between the second drainage pipe and the connecting pipe, producing an adsorption effect, and then being able to suck out the residual water in the sink and discharge it in turn along the second drainage pipe and the first drainage pipe, thereby making the drainage of the cleaning equipment more thorough and avoiding the contamination of the cleaning equipment by the residual water.
[0039] Specifically, the dishwasher of the present invention can clean items (such as plates, etc.) in the dishwasher. The dishwasher includes a sink 2, a first drain pipe 41, a second drain pipe 42 and a connecting pipe 43. One end of the first drain pipe 41 is connected to the sink 2 to drain the water in the sink 2, a first end of the second drain pipe 42 is connected to a water source, a second end of the second drain pipe 42 is connected to the first drain pipe 41, a first end of the connecting pipe 43 is connected to the sink 2, and a second end of the connecting pipe 43 is connected to the second drain pipe 42. The connection point between the connecting pipe 43 and the second drain pipe 42 is located between the first end and the second end of the second drain pipe 42. After the second drain pipe 42 is connected to the water source, the water flowing in the second drain pipe 42 can cause the connecting pipe 43 to generate negative pressure to drain the residual water in the sink 2.
[0040] For example, Figure 1 As shown, the dishwasher of the utility model comprises a shell 1 and a water tank 2 installed in the shell 1, a first drainage pipeline 41, a second drainage pipeline 42 and a connecting pipeline 43. The water tank 2 is arranged at the lower part of the dishwasher to hold cleaning water. The first drainage pipeline 41 is arranged in a horizontal direction. The right end of the first drainage pipeline 41 is connected to the water tank 2. The left end of the first drainage pipeline 41 extends out of the dishwasher and is connected to the drainage floor drain, so that the sewage in the water tank 2 can be discharged. The second drainage pipeline 42 is arranged in a horizontal direction. The right end of the second drainage pipeline 42 is connected to a water source. The left end of the second drainage pipeline 42 is connected to the first drainage pipeline 41. The connecting pipeline 43 is arranged in a vertical direction. The top end of the connecting pipeline 43 is connected to the water tank 2, and the bottom end of the connecting pipeline 43 is connected to the second drainage pipeline 43. The second drain pipe 42 is connected with the water source, and the connection part of the connecting pipe 43 and the second drain pipe 42 is located near the right end of the second drain pipe 42, that is, near the water source. The pipe section at the connection part of the second drain pipe 42 and the connecting pipe 43 is a reducer, and the pipe diameter becomes smaller here. When the second drain pipe 42 is connected to the water source, water flows along the second drain pipe 42. When flowing through the reducer, the flow rate of water increases. According to the Venturi effect, the water pressure becomes smaller. When the flow rate of water is controlled within a reasonable range, a negative pressure will be formed at the reducer, thereby generating an adsorption effect, and then the residual water in the water tank 2 can be sucked out, and discharged along the second drain pipe 42 and the first drain pipe 41 in turn, so that the drainage of the dishwasher is more thorough and the pollution of the dishwasher by the residual water is avoided.
[0041] It should be noted that the present invention does not limit the water source. For example, a person skilled in the art may set the water source to be the water inlet pipe, faucet or water tank of the dishwasher, etc. Such flexible adjustment and change does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.
[0042] Of course, the utility model preferably sets the water source as the water inlet pipe of the dishwasher, which has a simple structure, is easy to control, and saves costs.
[0043] It should also be noted that a one-way valve can also be provided at the bottom end of the connecting pipe 43 of the utility model to ensure that water can only flow toward the second drainage pipe 42 through the connecting pipe 43. However, in actual applications, when the flow rate of water in the second drainage pipe 42 is controlled within a reasonable range, a negative pressure will be formed at the reducer, and water will not flow into the connecting pipe 43. Instead, an adsorption effect will be generated to suck out the residual water in the water tank 2. For cost saving considerations, the utility model preferably does not provide a one-way valve at the bottom end of the connecting pipe 43.
[0044] Preferably, if Figure 1 As shown, the dishwasher of the present invention further comprises a valve assembly installed on the second drainage pipe 42 , and the valve assembly can prevent water in the second drainage pipe 42 from flowing back.
[0045] That is to say, the valve assembly on the second drainage pipe 42 can prevent the water in the second drainage pipe 42 from flowing back, that is, it can prevent the water in the second drainage pipe 42 from flowing back into the sink 2, and can also prevent the residual water in the sink 2 from flowing back to the water source through the second drainage pipe 42, thereby effectively avoiding the pollution of the sink 2 and the water source by the backflow water.
[0046] It should be noted that the present invention does not limit the type of valve assembly. For example, a person skilled in the art may set the valve assembly to be a solenoid valve or a one-way valve, etc., as long as the water in the second drainage pipe 42 can be prevented from flowing back. Such adjustment and change of the specific type of the valve assembly does not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.
[0047] Preferably, if Figure 1 As shown, the valve assembly of the present invention includes a first one-way valve 51 , which is arranged between a connection point between the connecting pipeline 43 and the second drainage pipeline 42 and a second end of the second drainage pipeline 42 .
[0048] For example, Figure 1 As shown, the first one-way valve 51 of the utility model is arranged between the left end of the second drainage pipe 42 and the reducer near the reducer. By setting the first one-way valve 51, after the residual water in the sink 2 is discharged, it can effectively prevent sewage from flowing back into the second drainage pipe 42, thereby polluting the sink 2 and the water source.
[0049] Preferably, if Figure 1As shown, the valve assembly of the present invention further includes a second one-way valve 52 , which is disposed between a connection point between the connecting pipeline 43 and the second drainage pipeline 42 and a first end of the second drainage pipeline 42 .
[0050] For example, Figure 1 As shown, the second one-way valve 52 of the utility model is arranged between the right end of the second drainage pipe 42 and the reducer, close to the reducer. By setting the second one-way valve 52, the sewage in the sink 2 can be prevented from polluting the water source through the second drainage pipe 42.
[0051] Preferably, if Figure 1 As shown, the dishwasher of the utility model further includes a drainage pump 3 , one end of the drainage pump 3 is connected to the water tank 2 , and the other end of the drainage pump 3 is connected to the first drainage pipeline 41 .
[0052] For example, Figure 1 As shown, the right end of the drain pump 3 of the present invention is connected to the water tank 2, and the left end of the drain pump 3 is connected to the first drain pipe 41. The water in the water tank 2 can be quickly pumped into the first drain pipe 41 for discharge through the drain pump 3, thereby improving the drainage efficiency of the dishwasher.
[0053] It should be noted that the utility model can also set a valve on the first drainage pipe 41 to prevent the water in the first drainage pipe 41 from flowing back. Those skilled in the art can set the valve as a one-way valve or a solenoid valve, etc. Such flexible adjustment and change does not deviate from the principle and scope of the utility model and should be limited within the protection scope of the utility model.
[0054] Preferably, if Figure 1 As shown, the dishwasher of the present invention further includes a first solenoid valve 61 , which is disposed on the first drainage pipe 41 to prevent water in the first drainage pipe 41 from flowing back.
[0055] For example, Figure 1 As shown, the first solenoid valve 61 of the utility model is arranged at the right end of the first drainage pipe 41 near the drainage pump 3. By installing the first solenoid valve 61, sewage can be effectively prevented from flowing back into the sink 2 through the first drainage pipe 41, thereby avoiding pollution of the sink 2.
[0056] The utility model preferably sets a first solenoid valve 61 on the first drainage pipeline 41, which can avoid the problem that the one-way valve is not effective due to fatigue of the one-way valve, thereby causing problems such as sewage backflow.
[0057] Preferably, if Figure 1 As shown, the dishwasher of the present invention further includes a breather 7 , which is disposed on the first drainage pipe 41 to balance the air pressure inside and outside the first drainage pipe 41 .
[0058] For example, Figure 1 As shown, the first drainage pipe 41 of the utility model is inverted U-shape in the breather 7, so that the liquid level of the first drainage pipe 41 can be increased to achieve the anti-siphon effect. The first drainage pipe 41 is connected to the external atmospheric pressure through the breather 7, so that the pressure difference between the internal air pressure of the first drainage pipe 41 and the external atmospheric pressure can be balanced, further improving the anti-siphon effect, preventing the clean water in the water tank 2 from being discharged, and avoiding dry burning of the heating components in the cleaning equipment.
[0059] Preferably, if Figure 1 As shown, the connection point between the second drainage pipeline 42 and the first drainage pipeline 41 of the present invention is located downstream of the respirator 7 .
[0060] For example, Figure 1 As shown, the connection point between the second drainage pipe 42 and the first drainage pipe 41 of the utility model is located on the left side of the respirator 7, close to the left end of the first drainage pipe 41. This arrangement makes the connection point between the second drainage pipe 42 and the first drainage pipe 41 closer to the drainage floor drain, so that the sewage in the second drainage pipe 42 can be quickly discharged.
[0061] Preferably, if Figure 1 As shown, the dishwasher of the present invention further includes a second solenoid valve 62 , which is disposed at the first end of the second drainage pipeline 42 to control the on / off state of the water source.
[0062] For example, Figure 1 As shown, the second solenoid valve 62 of the utility model is arranged at the right end of the second drainage pipeline 42 close to the water source, so that the on-off state of the water source can be controlled more intelligently.
[0063] The specific drainage process of the dishwasher of the present invention is as follows: after the washing program of the dishwasher is completed, the drainage pump 3 discharges the sewage in the water tank 2 through the first drainage pipe 41. After the drainage is completed, the first solenoid valve 61 is closed to prevent the sewage from flowing back. After standing for a period of time, when the residual water in the dishwasher is collected in the water tank 2, the second solenoid valve 62 is opened. When the water at the water source passes through the second drainage pipe 42, negative pressure is generated at the reducer, and the residual water in the water tank 2 is sucked away and discharged. After the drainage is completed, the second solenoid valve 62 is closed.
