Description

Technical Field

[0001] This invention relates to the field of washing equipment technology, and particularly to a washing mechanism, a dishwasher, a washing control method, and a control device. Background Technology

[0002] With the increasing popularity of home appliances, the demand for improvements in their functionality is also growing. For washing equipment such as dishwashers, the main improvement requirement lies in the high long-term cost of detergent. Therefore, consideration is being given to designing the washing mechanism to utilize high-pressure rinsing to reduce or eliminate the use of detergent.

[0003] However, using high-pressure rinsing to reduce or eliminate the use of detergent necessitates increasing the impact force of the water flow to compensate for any shortcomings in cleaning effectiveness caused by reducing or eliminating detergent. Based on existing washing methods, increasing the impact force of the water flow requires increasing the power of components such as the water pump, which leads to problems with high-intensity vibration and noise. Summary of the Invention

[0004] To address the problem that using high-pressure water jets to reduce or eliminate detergent usage can generate high levels of vibration and noise in existing dishwashers and other washing equipment, this invention proposes a washing mechanism, a dishwasher, a washing control method, and a control device.

[0005] In a first aspect, the present invention provides a washing mechanism, comprising a water supply component disposed on a water supply pipeline and an impact generating component disposed on the water supply component. The impact generating component includes a positive electrode and a negative electrode disposed at intervals inside the water supply component. When energized, the positive electrode and the negative electrode can generate a shock wave inside the water supply component based on the electrohydraulic effect.

[0006] In one embodiment, the water supply component has at least one water outlet, which is connected to a nozzle via a pipe.

[0007] In one embodiment, the water conveying component is located on the water conveying pipeline near the output end of the water pump.

[0009] Secondly, the present invention provides a dishwasher that includes the washing mechanism described above.

[0010] In one embodiment, the water supply component of the washing mechanism has two water outlets, which are respectively connected to the first spray arm and the second spray arm of the dishwasher via pipelines.

[0011] Thirdly, the present invention provides a washing control method, comprising:

[0012] Determine the duration of the power-on interval;

[0013] Each time the energizing interval is elapsed, the generating electrode of the impact generating component of the washing mechanism is momentarily energized once to generate an impact water flow based on the electrohydraulic effect.

[0014] In one implementation, it further includes:

[0015] Determine the washing stage;

[0016] The voltage value for energizing the generating electrode is determined based on the washing stage.

[0017] In one implementation, it further includes:

[0020] Fourthly, the present invention provides a washing control device, comprising:

[0021] An interval duration determination module, used to determine the power-on interval duration; and

[0022] A power-on control module is used to momentarily energize the generating electrode of the impact generating component of the washing mechanism once every time one of the power-on intervals has elapsed, so as to generate an impact water flow based on the electrohydraulic effect.

[0023] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present invention can be achieved.

[0024] The washing mechanism, dishwasher, washing control method, and control device provided by the present invention have at least the following advantages compared with the prior art:

[0034] The invention will now be further described with reference to the accompanying drawings.

[0035] Example 1

[0036] An embodiment of the present invention provides a washing mechanism, including a water supply component 9 disposed on a water supply pipeline and an impact generating component disposed on the water supply component 9. The impact generating component includes a positive electrode 1 and a negative electrode 2 disposed at intervals inside the water supply component 9. When energized, the positive electrode 1 and the negative electrode 2 can generate shock waves inside the water supply component 9 based on the electrohydraulic effect.

[0037] Specifically, this embodiment uses a dishwasher as an example to illustrate the technical solution of the present invention, as shown in the accompanying drawings. Figure 1 Figure 2 and Figure 3 As shown in the attached diagram, a water delivery component is installed on the dishwasher's water supply line (section 6 of the internal water supply pipe). This component is equipped with an impact generating assembly to create shock waves in the water flow. The water delivery component serves two purposes: facilitating the installation of the impact generating assembly and also functioning as a water distribution connector. Figure 1 As shown, the two protruding points on the water conveying component are the positive electrode 1 and the negative electrode 2 of the impact generating component. The positive electrode 1 and the negative electrode 2 penetrate through the water conveying component into its interior.

[0038] Driven by the dishwasher's water pump 10, water is propelled to the water delivery component. The water then flows through the inner water pipe 6 and is sprayed onto the tableware surface through the spray nozzles of the spray arm to rinse the tableware. When the impact generating component is momentarily energized, the component mounted on the water delivery component operates. Due to the electrohydraulic effect, a shock wave is instantaneously generated inside the water delivery component, such as... Figure 3 As shown, due to the instantaneous shock wave generated by the electrohydraulic effect, the pressure of the two water flows in the water supply component towards the spray arm increases instantaneously. Finally, high-pressure water flows are ejected through the nozzles on the first spray arm 7 and the second spray arm 8 to impact the tableware. This can achieve a higher impact force than the water flow driven by the original water pump 10, easily washing away the contaminants on the tableware.

[0039] Furthermore, due to the intermittent and instantaneous nature of the electrohydraulic effect, the resulting shock waves are also intermittent, thus avoiding prolonged high-pressure water rinsing and the noise caused by prolonged continuous rinsing. Simultaneously, the washing mechanism in this embodiment does not impose any requirements on the specifications or operating power of the dishwasher's original water pump 10, therefore avoiding vibration problems caused by increasing the specifications or operating power of the water pump 10.

[0040] Furthermore, the water supply component 9 has at least one water outlet, which is connected to a spray head via a pipe. In this embodiment, when applied to a dishwasher, the water supply component has a first water outlet 3 and a second water outlet 4 respectively connected to the first spray arm 7 and the second spray arm 8.

[0041] Of course, when applied to other equipment that requires high-pressure washing, the number of water outlets can be adjusted accordingly, such as high-pressure car wash equipment.

[0042] Furthermore, the water conveying component 9 is located on the water conveying pipeline near the output end of the water pump 10. When the water conveying component is impacted due to the electrohydraulic effect, it will generate a certain degree of vibration. The structure of the water conveying pipeline near the water pump 10 is relatively stable and rigid, so the vibration can be reduced to a certain extent from the impact of the entire pipeline structure.

[0043] Furthermore, it also includes a heating element installed on the water supply pipeline, which has multiple heating levels. By combining high-pressure rinsing with heating of the washing water, the shortcomings in cleaning effectiveness that may arise from reducing or eliminating the use of detergent can be further compensated for.

[0044] Example 2

[0045] This embodiment is an improvement on embodiment 1. For some of the same content, please refer to embodiment 1. This embodiment will not repeat the same content.

[0046] This embodiment mainly focuses on improving the structure of the water conveying component. The primary consideration is that the shock wave generated within the component should ideally propagate along the water conveying direction, i.e., to the water-using end, minimizing the risk of the shock wave propagating towards the water-incoming end (i.e., the end where the water pump 10 is located). Therefore, this is achieved by designing a check valve-like structure within the water conveying component.

[0047] In this embodiment, a blocking component is provided at the water inlet 5 of the water supply component. The blocking component is a conical cylindrical structure made of elastic material. The circumference of the part of the blocking component corresponding to the bottom of the cone is connected to the inner wall of the water inlet 5 of the water supply component and maintains the seal at this point. The part of the blocking component corresponding to the top of the cone has a flow hole, and the direction from the bottom of the cone to the top of the cone corresponds to the direction of water flow.

[0048] During normal water supply, water flows from the bottom to the top of the cone of the baffle. Under the pressure of the water flow, the flow-through orifice at the top of the cone deforms locally and expands outward, increasing the orifice size and enabling a larger flow rate. When an impact occurs in the water supply component due to the electrohydraulic effect, a portion of the shock wave acts on the top of the cone of the baffle through the water flow. Under the impact pressure, the flow-through orifice deforms locally and contracts inward, reducing the orifice diameter. This reduces the intensity of the shock wave transmission to the water pump 10 and allows the shock wave to be reflected to the water-using end, forming a high-pressure water flow for impact cleaning, thus improving the utilization rate of impact energy.

[0049] Example 3

[0050] An embodiment of the present invention provides a dishwasher, characterized in that it includes the washing mechanism described above, and thus possesses all the technical effects thereof.

[0051] Furthermore, as shown in the attached figure Figure 2 As shown, the water supply component 9 of the washing mechanism has two water outlets, which are respectively connected to the first spray arm 7 and the second spray arm 8 of the dishwasher through pipes.

[0052] Example 4

[0053] An embodiment of the present invention provides a washing control method, comprising:

[0054] Step S000: Proceed to the pre-wash procedure;

[0055] Step S100: Determine the power-on interval duration and washing stage;

[0056] Step S200: Determine the target water temperature and the voltage value for energizing the generating electrode according to the washing stage, and heat the washing water delivered to the washing mechanism according to the target water temperature;

[0057] Step S300: After each energizing interval, the generating electrode of the impact generating component of the washing mechanism is energized instantaneously once according to a determined voltage value to generate an impact water flow based on the electrohydraulic effect.

[0058] Specifically, as shown in the attached diagram. Figure 4 As shown, the washing process includes pre-wash, washing, and rinsing programs, with the washing program primarily serving a cleaning function. The washing program can include multiple washing stages, each with different washing parameters. These parameters include the voltage value (a higher voltage value results in a stronger impact), the target water temperature, and potentially the duration of the power-on interval (a shorter interval results in more frequent impacts).

[0059] In this embodiment, please refer to the accompanying drawings. Figure 4 The washing program used in dishwashers mainly includes three washing stages. Because the substances and ion counts in the water differ in each stage, the electrohydraulic effect voltage is set to V1 for the first stage, V2 (V2 > V1) for the second stage, and V1 again for the third stage. For example... Figure 4 As shown, after a regular pre-wash, the dishwasher enters the first, second, and third stages, all of which employ high-pressure pulse rinsing based on the electrohydraulic effect. The target water temperature increases sequentially during each washing stage, T3 > T2 > T1, using high-temperature water to remove grease from the surface of the dishes. Then, a rinsing stage is performed. This rinsing stage does not involve pulse rinsing; it primarily serves to remove any secondary contamination remaining on the surface of the dishes before the washing cycle ends. Multiple cycles can be performed within a single washing stage.

[0060] Example 5

[0061] An embodiment of the present invention provides a washing control device, comprising:

[0062] An interval duration determination module, used to determine the power-on interval duration; and

[0063] The power-on control module is used to momentarily energize the generating electrode of the impact generating component of the washing mechanism once every power-on interval to generate an impact water flow based on the electrohydraulic effect.
