Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a dishwasher and a washing control method thereof. Background Art

[0002] Currently, there are two types of dishwashers on the market: those without water tanks and those with water tanks. The first type is without water tanks, and the water inlet and drainage of the dishwasher adopt the traditional direct connection with the household water pipes, and the structure is relatively simple. The second type is with a water tank. On the one hand, water is supplied by a built-in clean water tank, and on the other hand, a waste water tank is set up to recycle washing waste water to avoid wasting water resources. At present, the clean water tank and waste water tank of most dishwashers are installed on the left and right sides of the dishwasher respectively. In addition to increasing the cost of the machine, the setting of two water tanks also fills up the space on the left and right sides of the dishwasher, which will affect the installation of other functions of the dishwasher. Summary of the Invention

[0003] Based on this, it is necessary to provide a dishwasher and a washing control method thereof, which utilizes the cooperation of the water inlet component and the washing component to realize the integrated design of the clean water tank and the waste water tank, saving the installation space of the dishwasher while effectively reducing the energy consumption of the dishwasher.

[0004] A dishwasher comprises: an inner tank for accommodating tableware; a water tank disposed on an outer wall of the inner tank and connected to the inner tank for heat conduction; a washing assembly, the washing assembly being in communication with the inner tank and the water tank, the water tank being used to supply washing water to the washing assembly, and the washing assembly being used to spray washing water onto the tableware in the inner tank; a water inlet assembly, the water inlet assembly being in communication with an external water source and the water tank, the water inlet assembly being used to deliver clean washing water to the water tank; a heating device disposed on the washing assembly and being used to heat washing water; wherein the dishwasher has at least a first mode and a second mode, wherein when in the first mode, the washing assembly sprays high-temperature washing water onto the tableware in the inner tank, and the water tank stores clean washing water for preheating by absorbing heat; and when in the second mode, high-temperature washing wastewater in the inner tank is delivered to the water tank through the washing assembly to release heat to dry the tableware in the inner tank.

[0005] The present application provides a dishwasher that forms a water circulation system by providing a washing assembly that connects the inner tank and the water tank, respectively. With the cooperation of the water inlet assembly and the washing assembly, a single water tank can serve as both a clean water storage system and a waste water storage system. Furthermore, by connecting the water tank and the inner tank, heat transfer between the two is achieved. When hot water is used for washing in the inner tank, the water tank can store wash water for heat absorption and supply it to the washing assembly after the heat absorption is completed. This reduces the amount of electricity required for heating by reducing the heat absorption temperature difference. When washing is completed, the high-temperature wastewater generated by washing can be transferred to the water tank for heat dissipation and transfer to the inner tank. This allows the dishwasher to preheat clean water in the water tank and release heat from the high-temperature wastewater in the water tank to dry dishes in different usage modes. The above structure not only achieves an integrated design of the clean water tank and the wastewater tank, thereby reducing the number of parts and saving installation space, but also effectively reduces the energy consumption of the dishwasher.

[0006] In one embodiment, the washing assembly includes a water cup, a water delivery assembly and a spray arm, the spray arm is arranged in the inner tank, the water delivery assembly is respectively connected to the water cup, the water tank and the spray arm, the water tank supplies washing water to the water cup through the water delivery assembly, the heating device is arranged on the water cup or the water delivery assembly, the water cup is provided with a first liquid flow end, when in the first mode, the washing water in the water cup enters the spray arm through the first liquid flow end and the water delivery assembly and is sprayed onto the tableware in the inner tank through the spray hole of the spray arm; when in the second mode, the high-temperature washing waste water in the inner tank is transported to the water tank through the water delivery assembly to release heat to dry the tableware in the inner tank. By adopting the above structure, first, before the first washing, the water cup can obtain clean washing water from the water tank for use by the spray arm; when the first mode is executed, the washing water in the water cup will be heated by the heating device and sucked out by the water delivery component to the spray arm for hot water washing. Since the washing water is heated, the temperature of the dishwasher's inner tank is higher than the temperature of the water tank. At this time, the clean washing water in the water tank is in a heat absorption stage, and will absorb heat from the inner tank to increase the temperature of the clean water in the water tank, thereby preheating. The preheated clean washing water flows to the water cup through the water delivery component for use, thereby reducing the amount of electricity required for heating by reducing the heat absorption temperature difference; when the second mode is executed, the washing work of the dishwasher is completed, and there is high-temperature washing waste water to be discharged in the inner tank. The high-temperature washing waste water is discharged into the water tank through the water delivery component. At this time, the high-temperature washing waste water in the water tank can release heat and transfer it to the inner tank. The released heat can be used to dry the tableware in the dishwasher, thereby improving the drying effect.

[0007] In one embodiment, the water inlet assembly is used to deliver clean washing water to the water tank when the first mode is executed and / or before the first mode is executed.

[0008] In one embodiment, the water cup is provided with a first liquid inlet end, which is in communication with the inner tank and is configured to receive the wastewater from the inner tank. When in the second mode, the high-temperature wastewater from the inner tank is sequentially transported through the water cup and the water delivery assembly to the water tank. By providing a water cup for receiving the wastewater from the inner tank, the recovered wastewater can be drawn out through the water delivery assembly and then re-supplied to the spray arm for washing, thereby enabling the reuse of the wash water and conserving water resources.

[0009] In one embodiment, the water cup is positioned at the bottom of the inner container, which is provided with a drain port connected to the first liquid inlet. With this structure, wash water entering the inner container, after washing the dishes, falls to the bottom of the inner container under the action of gravity and further flows back into the water cup, thereby simplifying the design of the power assembly and forming a simple water circulation system.

[0010] In one embodiment, a second liquid outlet is provided at the bottom of the water tank, connected to the first liquid outlet via the water delivery assembly. The second liquid outlet is located at a higher level than the first liquid outlet. This structure allows the wash water in the water tank to flow through the second liquid outlet under gravity toward the first liquid outlet, into the water cup, and then into the spray arm. This reduces the design of the power assembly and simplifies the structure of the water delivery assembly, thereby improving the installation efficiency of the dishwasher.

[0011] In one embodiment, it also includes a water tank valve and a water diverter valve, the water delivery component includes a first washing pump and a pipeline component, the water inlet end of the first washing pump is connected to the first liquid end through the pipeline component, the two ends of the water tank valve are respectively connected to the water outlet end of the first washing pump and the water tank through the pipeline component, the water tank valve is used to connect or disconnect the first washing pump and the water tank, the two ends of the water diverter valve are respectively connected to the water outlet end of the first washing pump and the spray arm through the pipeline component, the water diverter valve is used to connect or disconnect the first washing pump and the spray arm, the first washing pump is used to deliver washing water to the spray arm and / or deliver high-temperature washing wastewater to the water tank. With the above structure, when the water tank valve is open and the first washing pump is closed, washing water injected into the water tank through the water inlet assembly flows to the water cup under the action of gravity. When the water tank valve is closed and the water diversion valve is open, the first washing pump operates to supply the washing water in the water cup to the spray arm for spraying. When the water tank valve is open and the water diversion valve is closed, the first washing pump operates to transfer the high-temperature washing wastewater flowing from the inner tank into the water cup to the water tank for storage, releasing heat and achieving the effect of drying dishes. The coordination of the water tank valve, the water diversion valve, and the first washing pump simplifies the structure of the water delivery assembly and achieves effective control of the flow of washing water.

[0012] In one embodiment, the water delivery assembly includes a first wash pump, a second wash pump, and a piping assembly. The first wash pump connects the first liquid-passing end and the spray arm via the piping assembly and is used to deliver wash water to the spray arm. The second wash pump connects the first liquid-passing end and the water tank via the piping assembly and is used to deliver high-temperature wastewater to the water tank. This structure simplifies the control process and reduces the risk of dishwasher malfunction due to damage to individual components.

[0013] In one embodiment, a water tank valve is further included, wherein both ends of the water tank valve are respectively connected to the water outlet end of the second washing pump and the water tank through the pipeline assembly, and the water tank valve is used to connect or disconnect the second washing pump and the water tank.

[0014] In one embodiment, the heating device includes a fluid channel, the ends of which are connected to the first liquid transfer port and the water inlet port of the first wash pump, respectively, via the pipe assembly. The heating device is configured to heat the wash water flowing through the fluid channel. Long dishwasher wash times have long been a common complaint, with heating the wash water accounting for a significant portion of the wash time. By adopting the above-described structure, the heating device need not heat all of the liquid in the water cup simultaneously, but only the liquid flowing through the fluid channel. This increases the rate at which the wash water temperature rises, thereby improving washing efficiency.

[0015] In one embodiment, the heating device includes a shell and a heating element, the shell is connected to the first liquid end and the water inlet end of the first washing pump through the pipe assembly respectively, the shell is provided with the fluid channel, the heating element is arranged on the shell, and the heating element is used to heat the washing water in the fluid channel.

[0016] In one embodiment, the device further includes a drain assembly, one end of which communicates with the water tank and the other end of which communicates with the exterior of the dishwasher. After the dishwasher completes drying, the waste water in the water tank is drained to the exterior of the dishwasher through the drain assembly. By providing an independent drain channel on the water tank, the waste water does not need to flow back into the water cup, but is instead drained through the cup. This helps keep the inner cavity of the dishwasher dry and the dishes cleaner and more hygienic.

[0017] A second aspect of the present application provides a washing control method for a dishwasher.

[0018] A washing control method for a dishwasher, the dishwasher comprising an inner tank, a water tank, a washing assembly, a water inlet assembly, and a heating device, the water tank being connected to the outer wall of the inner tank for heat conduction, the washing assembly being communicated with the inner tank and the water tank respectively, the water tank being used to supply washing water to the washing assembly, the washing assembly being used to spray washing water onto the dishes in the inner tank, the water inlet assembly being communicated with an external water source and the water tank respectively, the water inlet assembly being used to deliver clean washing water to the water tank, the heating device being provided on the washing assembly, and the heating device being used to heat Washing water, the washing control method includes the following steps: S2: the heating device is started to heat the washing water in the washing component, and the washing component sprays the heated high-temperature washing water onto the tableware in the inner tank for cleaning. At the same time, the washing water stored in the water tank absorbs heat for preheating; S3: the washing water in the water tank is supplied to the washing component after preheating; S4: after cleaning is completed, the washing component transports the high-temperature washing waste water in the inner tank to the water tank to release heat, and uses heat transfer to dry the tableware in the inner tank. The second aspect of the present application provides a washing control method for a dishwasher. With the cooperation of a water inlet component and a washing component, a single water tank can have both the functions of clean water storage and waste water storage, and mutual heat transfer is achieved by connecting the water tank and the inner tank. When hot water is used for washing in the inner tank, the water tank can store washing water for heat absorption and supply it to the washing component after the heat absorption is completed, thereby reducing the amount of electricity required for heating by reducing the heat absorption temperature difference. When washing is completed, the high-temperature waste water generated by washing can be output to the water tank for heat dissipation and transfer the heat to the inner tank, so that in different usage modes of the dishwasher, the functions of preheating clean water in the water tank and releasing heat from the high-temperature waste water in the water tank to dry dishes can be achieved.

[0019] In one embodiment, the washing component includes a water cup, a water delivery component and a spray arm, the spray arm is arranged in the inner tank, the water delivery component is connected to the water cup, the water tank and the spray arm respectively, the heating device is arranged on the water cup or the water delivery component, the water cup is provided with a first liquid inlet end, the first liquid inlet end is connected to the inner tank for receiving the washing wastewater in the inner tank, and the specific steps of the washing control method are as follows: S2: the heating device is started to heat the washing water in the water cup or flowing through the water delivery component, the water delivery component works to supply the heated high-temperature washing water to the spray arm to spray and clean the tableware in the inner tank, and at the same time, the washing water stored in the water tank absorbs heat for preheating; S3: after the washing water in the water tank is preheated, it is delivered to the water cup through the water delivery component for use; S4: after cleaning is completed, the water delivery component is started to deliver the high-temperature washing wastewater in the inner tank that flows back into the water cup into the water tank to release heat, and the tableware in the inner tank is dried by heat transfer. When the dishwasher performs hot water washing, the washing water in the water cup will be heated by the heating device and sucked out by the water supply assembly to the spray arm for hot water washing. Since the washing water is heated, the temperature of the dishwasher's inner tank is higher than the temperature of the water tank. At this time, the clean washing water in the water tank is in the heat absorption stage, and will absorb heat from the inner tank to increase the temperature of the clean water in the water tank, thereby preheating. By preheating, the heat absorption temperature difference is reduced, thereby reducing the amount of electricity required for heating by the heating device; when the dishwasher's cleaning work is completed, the high-temperature washing waste water in the inner tank will flow back into the water cup and be transported to the water tank through the water supply assembly. At this time, the high-temperature washing waste water in the water tank can release heat and transfer it to the inner tank. The released heat can be used to dry the tableware in the dishwasher, thereby improving the drying effect.

[0020] In one embodiment, it also includes a water tank valve and a water diversion valve, the water delivery component includes a first washing pump and a pipe component, the water inlet end of the first washing pump is connected to the first liquid end through the pipe component, the two ends of the water tank valve are respectively connected to the water outlet end of the first washing pump and the water tank through the pipe component, and the two ends of the water diversion valve are respectively connected to the water outlet end of the first washing pump and the spray arm through the pipe component; the specific steps of S2 are as follows: S21: the water tank valve is closed and the water diversion valve is opened; S22: at the same time as or before the first washing pump is started, the water inlet component is opened to inject washing water into the water tank to absorb heat for preheating; S23: the heating device is started to heat the water in the cup or The washing water flowing through the pipe assembly is heated, and the first washing pump is started to supply the heated high-temperature washing water to the spray arm to spray and clean the tableware in the inner tank; the specific steps of S3 are as follows: after the washing water in the water tank is preheated, the water tank valve is opened, the first washing pump is shut down, and the preheated water in the water tank flows to the water cup for use; the specific steps of S4 are as follows: S41: the water tank valve is opened, and the water diversion valve is closed; S42: the first washing pump is started to transport the high-temperature washing waste water that flows back from the inner tank to the water cup into the water tank; S43: the water tank valve is closed, waiting for the high-temperature washing waste water to release heat in the water tank, and the tableware in the inner tank is dried by heat transfer. When the water tank valve is closed and the diverter valve is open, the first wash pump operates to supply the washing water in the cup to the spray arm for spraying. Simultaneously, the water tank is filled with water through the water inlet assembly, allowing the stored washing water to absorb heat and preheat. When the washing water in the tank has been preheated to a preset temperature or for a preset time, the water tank valve opens and the first wash pump closes, allowing the preheated washing water to flow to the cup under gravity for use. When the dishwasher is finished cleaning, the water tank valve opens and the diverter valve closes, allowing the first wash pump to transfer the high-temperature wastewater from the inner tank to the cup and store it in the water tank to release heat and achieve the effect of drying the dishes.

[0041] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] The following describes dishwashers according to some embodiments of the present invention with reference to the accompanying drawings.

[0044] like Figures 1 to 4 As shown, this embodiment discloses a dishwasher, comprising: an inner tank 1, which is used to accommodate tableware; a water tank 2, which is arranged on the outer wall of the inner tank 1 and connected to the inner tank 1 for heat conduction; a washing assembly 3, which is respectively connected to the inner tank 1 and the water tank 2, and is used to supply washing water to the washing assembly 3, and the washing assembly 3 is used to spray washing water onto the tableware in the inner tank 1; a water inlet assembly 4, which is respectively connected to an external water source and the water tank 2, and is used to transport clean washing water to the water tank 2; a heating device 5, which is arranged on the washing assembly 3 and is used to heat washing water; wherein the dishwasher has at least a first mode and a second mode, when in the first mode, the washing assembly 3 sprays high-temperature washing water onto the tableware in the inner tank 1, and the clean washing water is stored in the water tank 2 to absorb heat and preheat, and when in the second mode, the high-temperature washing wastewater in the inner tank 1 is transported to the water tank 2 through the washing assembly 3 to release heat to dry the tableware in the inner tank 1.

[0045] The present application provides a dishwasher that forms a water circulation system by providing a washing assembly 3 that connects the inner tank 1 and the water tank 2, respectively. With the cooperation of the water inlet assembly 4 and the washing assembly 3, the single water tank 2 can serve as both a clean water storage system and a waste water storage system. Furthermore, by connecting the water tank 2 and the inner tank 1, heat transfer between the water tank 2 and the inner tank 1 is achieved. When hot water is used for washing in the inner tank 1, the water tank 2 can store the wash water for heat absorption and supply it to the washing assembly 3 after the heat absorption is completed. This reduces the amount of electricity required for heating by reducing the heat absorption temperature difference. When washing is completed, the high-temperature wastewater generated by washing can be transferred to the water tank 2 for heat dissipation and transfer to the inner tank 1. Thus, in different usage modes of the dishwasher, the clean water in the water tank 2 can be preheated, and the high-temperature wastewater in the water tank 2 can release heat to dry dishes. By adopting the above structure, not only is the clean water tank 2 and the wastewater tank 2 integrated into a design that reduces the number of parts and saves installation space for the dishwasher, but the energy consumption of the dishwasher is also effectively reduced.

[0046] like Figures 1 to 4As shown, in addition to the features of the above embodiment, this embodiment further defines: the washing assembly 3 includes a water cup 31, a water delivery assembly 32 and a spray arm 33, the spray arm 33 is arranged in the inner tank 1, the water delivery assembly 32 is respectively connected to the water cup 31, the water tank 2 and the spray arm 33, the water tank 2 supplies washing water to the water cup 31 through the water delivery assembly 32, the heating device 5 is arranged on the water cup 31 or the water delivery assembly 32, the water cup 31 is provided with a first liquid flow end 311, when in the first mode, the washing water in the water cup 31 enters the spray arm 33 through the first liquid flow end 311 and the water delivery assembly 32 and is sprayed onto the tableware in the inner tank 1 through the spray hole of the spray arm 33; when in the second mode, the high-temperature washing wastewater in the inner tank 1 is delivered to the water tank 2 through the water delivery assembly 32 to release heat to dry the tableware in the inner tank 1. By adopting the above structure, first, before the initial wash, the water cup 31 can obtain clean wash water from the water tank 2 for use by the spray arm 33; when executing the first mode, the wash water in the water cup 31 will be heated by the heating device 5 and sucked out by the water delivery component 32 to the spray arm 33 for hot water washing. Since the wash water is heated, the temperature of the dishwasher inner tank 1 is higher than that of the water tank 2. At this time, the clean wash water in the water tank 2 is in a heat absorption stage, and will absorb heat from the inner tank 1 to increase the temperature of the clean water in the water tank 2, thereby preheating it. The preheated clean wash water flows to the water cup 31 through the water delivery component 32 for use, thereby reducing the power required for heating by reducing the heat absorption temperature difference; when executing the second mode, the washing work of the dishwasher is completed, and there is high-temperature wash waste water to be discharged in the inner tank 1. The high-temperature wash waste water is discharged into the water tank 2 through the water delivery component 32. At this time, the high-temperature wash waste water in the water tank 2 can release heat and transfer it to the inner tank 1. The released heat can be used to dry the dishes in the dishwasher, improving the drying effect.

[0047] In addition to the features of the above embodiment, this embodiment further defines that: the water inlet assembly 4 is used to deliver clean washing water to the water tank 2 when the first mode is executed and / or before the first mode is executed.

[0048] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiment, this embodiment further defines: a water cup 31 is provided with a first liquid inlet end 312, which is in communication with the inner liner 1 and is used to receive the washing wastewater in the inner liner 1. When in the second mode, the high-temperature washing wastewater in the inner liner 1 is sequentially transported to the water tank 2 through the water cup 31 and the water delivery assembly 32. By providing the water cup 31 for receiving the washing wastewater in the inner liner 1, the recovered washing wastewater can be sucked out by the water delivery assembly 32 and then supplied to the spray arm 33 for washing, thereby enabling the washing water to be reused multiple times, thereby achieving the effect of saving water resources.

[0049] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiment, this embodiment further defines: a water cup 31 is disposed at the bottom of the inner container 1, and a liquid discharge port is provided at the bottom of the inner container 1, connected to the first liquid inlet end 312. With this structure, wash water entering the inner container 1, after washing the dishes, falls to the bottom of the inner container 1 under the action of gravity and further flows back into the water cup 31, thereby simplifying the design of the power component and forming a simple water circulation system.

[0050] like Figure 1 and Figure 3 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further provides: a second liquid-passing end 21 is provided at the bottom of the water tank 2. The second liquid-passing end 21 communicates with the first liquid-passing end 311 via a water delivery assembly 32, and the second liquid-passing end 21 is located at a higher level than the first liquid-passing end 311. This structure allows wash water within the water tank 2 to flow through the second liquid-passing end 21 to the first liquid-passing end 311 under the action of gravity, into the water cup 31, and then to be consumed by the spray arm 33. This reduces the design of the power assembly and simplifies the structure of the water delivery assembly 32, thereby improving the installation efficiency of the dishwasher.

[0051] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: it also includes a water tank valve 6 and a water diverter valve 7, the water delivery component 32 includes a first washing pump 321 and a pipe component 322, the water inlet end of the first washing pump 321 is connected to the first liquid end 311 through the pipe component 322, the two ends of the water tank valve 6 are respectively connected to the water outlet end of the first washing pump 321 and the water tank 2 through the pipe component 322, the water tank valve 6 is used to connect or disconnect the first washing pump 321 and the water tank 2, the two ends of the water diverter valve 7 are respectively connected to the water outlet end of the first washing pump 321 and the spray arm 33 through the pipe component 322, the water diverter valve 7 is used to connect or disconnect the first washing pump 321 and the spray arm 33, the first washing pump 321 is used to deliver washing water to the spray arm 33 and / or deliver high-temperature washing wastewater to the water tank 2. With the above structure, when the water tank valve 6 is open and the first washing pump 321 is closed, the washing water injected into the water tank 2 through the water inlet assembly 4 can flow to the water cup 31 under the action of gravity. When the water tank valve 6 is closed and the water diversion valve 7 is open, the first washing pump 321 operates to supply the washing water in the water cup 31 to the spray arm 33 for spraying. When the water tank valve 6 is open and the water diversion valve 7 is closed, the first washing pump 321 operates to transfer the high-temperature washing wastewater flowing from the inner tank 1 into the water cup 31 to the water tank 2 for storage, releasing heat and achieving the effect of drying the dishes. The coordination of the water tank valve 6, the water diversion valve 7, and the first washing pump 321 can simplify the structure of the water delivery assembly 32 and achieve effective control of the flow of washing water.

[0052] In addition to the features of the above embodiment, this embodiment further defines that the water delivery assembly 32 includes a first wash pump 321, a second wash pump, and a pipe assembly 322. The first wash pump 321 is connected to the first liquid outlet 311 and the spray arm 33 via the pipe assembly 322. The first wash pump 321 is used to deliver wash water to the spray arm 33. The second wash pump is connected to the first liquid outlet 311 and the water tank 2 via the pipe assembly 322. The second wash pump is used to deliver high-temperature wastewater to the water tank 2. By adopting the above structure, independent first and second wash pumps are provided for delivering wash water to the spray arm 33 and high-temperature wastewater to the water tank 2, respectively. This simplifies the control process and reduces the risk of failure of the entire dishwasher due to damage to individual components.

[0053] In addition to the features of the above embodiments, this embodiment is further defined as follows: it also includes a water tank valve 6, the two ends of which are respectively connected to the water outlet end of the second washing pump and the water tank 2 through a pipe assembly 322, and the water tank valve 6 is used to connect or disconnect the second washing pump and the water tank 2.

[0054] In addition to the features of the aforementioned embodiment, this embodiment further provides that: heating device 5 is provided with a fluid channel, the ends of which are connected to first liquid passage 311 and the water inlet of first wash pump 321, respectively, via pipe assembly 322. Heating device 5 is used to heat the wash water flowing through the fluid channel. Long dishwasher wash times have long been a user complaint, with heating the wash water accounting for a significant portion of the wash time. By adopting the aforementioned structure, heating device 5 need not simultaneously heat all the liquid in water cup 31; it only heats the liquid flowing through the fluid channel, increasing the rate at which the wash water temperature rises, thereby improving washing efficiency.

[0055] In addition to the features of the above embodiment, this embodiment further defines that: the heating device 5 includes a shell and a heating element, the shell is connected to the first liquid end 311 and the water inlet end of the first washing pump 321 through a pipe assembly 322, the shell is provided with a fluid channel, and the heating element is arranged on the shell, and the heating element is used to heat the washing water in the fluid channel.

[0056] In addition to the features of the above-described embodiment, this embodiment further comprises a drain assembly, one end of which communicates with water tank 2 and the other end of which communicates with the exterior of the dishwasher. After the dishwasher completes drying, the wastewater in water tank 2 is drained to the exterior of the dishwasher through the drain assembly. By providing an independent drain channel in water tank 2, the wastewater is discharged through water cup 31 without having to flow back into the inner cavity of inner container 1, thereby maintaining a dry interior and ensuring cleaner and more hygienic dishware.

[0057] The second aspect of the present application provides a washing control method for a dishwasher, such as Figures 1 to 5As shown, the dishwasher includes an inner tank 1, a water tank 2, a washing component 3, a water inlet component 4 and a heating device 5. The water tank 2 is connected to the outer wall of the inner tank 1 for heat conduction. The washing component 3 is communicated with the inner tank 1 and the water tank 2 respectively. The water tank 2 is used to supply washing water to the washing component 3, and the washing component 3 is used to spray washing water onto the tableware in the inner tank 1. The water inlet component 4 is communicated with an external water source and the water tank 2 respectively. The water inlet component 4 is used to transport clean washing water to the water tank 2. The heating device 5 is arranged on the washing component 3 and is used to heat washing water. The washing control method includes the following steps: S2: the heating device 5 is started to heat the washing water in the washing component 3. The washing component 3 works to spray the heated high-temperature washing water onto the tableware in the inner tank 1 for cleaning. At the same time, the washing water stored in the water tank 2 absorbs heat for preheating; S3: the washing water in the water tank 2 is preheated and supplied to the washing component 3 for use; S4: after cleaning is completed, the washing component 3 transports the high-temperature washing waste water in the inner tank 1 to the water tank 2 to release heat, and uses heat transfer to dry the tableware in the inner tank 1. The second aspect of the present application provides a washing control method for a dishwasher. With the cooperation of the water inlet component 4 and the washing component 3, a single water tank 2 can have both the functions of clean water storage and waste water storage, and mutual heat transfer is achieved by connecting the water tank 2 and the inner tank 1. When hot water is used for washing in the inner tank 1, the water tank 2 can store washing water for heat absorption and supply it to the washing component 3 after the heat absorption is completed. The amount of electricity required for heating is reduced by reducing the heat absorption temperature difference. When washing is completed, the high-temperature waste water generated by washing can be transported to the water tank 2 for heat dissipation and the heat is transferred to the inner tank 1. Therefore, in different usage modes of the dishwasher, the functions of preheating clean water in the water tank 2 and releasing heat from the high-temperature waste water in the water tank 2 to dry dishes can be achieved.

[0058] like Figure 1 and Figure 6As shown, in addition to the features of the above embodiment, this embodiment further defines: the washing assembly 3 includes a water cup 31, a water delivery assembly 32 and a spray arm 33, the spray arm 33 is arranged in the inner tank 1, the water delivery assembly 32 is connected to the water cup 31, the water tank 2 and the spray arm 33 respectively, the heating device 5 is arranged on the water cup 31 or the water delivery assembly 32, the water cup 31 is provided with a first liquid inlet end 312, the first liquid inlet end 312 is connected to the inner tank 1 for receiving the washing wastewater in the inner tank 1, and the specific steps of the washing control method are as follows: S2: the heating device 5 starts to heat the water in the water cup 31 or the water tank 2 The washing water flowing through the water supply component 32 is heated, and the water supply component 32 works to supply the heated high-temperature washing water to the spray arm 33 to spray and clean the tableware in the inner tank 1. At the same time, the washing water stored in the water tank 2 absorbs heat and is preheated; S3: After the washing water in the water tank 2 is preheated, it is transported to the water cup 31 for use through the water supply component 32; S4: After cleaning is completed, the water supply component 32 starts to transport the high-temperature washing waste water in the inner tank 1 that flows back to the water cup 31 into the water tank 2 to release heat, and the tableware in the inner tank 1 is dried by heat transfer. When the dishwasher performs hot water washing, the washing water in the water cup 31 will be heated by the heating device 5 and sucked out by the water delivery component 32 to the spray arm 33 for hot water washing. Since the washing water is heated, the temperature of the dishwasher's inner tank 1 is higher than the temperature of the water tank 2. At this time, the clean washing water in the water tank 2 is in the heat absorption stage, and will absorb heat from the inner tank 1 to increase the temperature of the clean water in the water tank 2, thereby preheating. The preheating reduces the heat absorption temperature difference, thereby reducing the amount of electricity required for heating by the heating device 5; when the dishwasher's cleaning work is completed, the high-temperature washing waste water in the inner tank 1 will flow back into the water cup 31 and be transported to the water tank 2 through the water delivery component 32. At this time, the high-temperature washing waste water in the water tank 2 can release heat and transfer it to the inner tank 1. The released heat can be used to dry the tableware in the dishwasher, thereby improving the drying effect.

[0059] like Figures 1 to 4 、 Figure 7 and Figure 8As shown, in addition to the features of the above embodiment, this embodiment is further defined as follows: it also includes a water tank valve 6 and a water diverter valve 7, the water delivery assembly 32 includes a first washing pump 321 and a pipe assembly 322, the water inlet end of the first washing pump 321 is connected to the first liquid end 311 through the pipe assembly 322, the two ends of the water tank valve 6 are respectively connected to the water outlet end of the first washing pump 321 and the water tank 2 through the pipe assembly 322, and the two ends of the water diverter valve 7 are respectively connected to the water outlet end of the first washing pump 321 and the spray arm 33 through the pipe assembly 322; the specific steps of S2 are as follows: S21: the water tank valve 6 is closed, and the water diverter valve 7 is opened; S22: at the same time as or before the first washing pump 321 is started, the water inlet assembly 4 is opened to inject washing water into the water tank 2 to absorb heat for preheating; S23 : The heating device 5 starts to heat the washing water in the water cup 31 or flowing through the pipe assembly 322, and the first washing pump 321 starts to supply the heated high-temperature washing water to the spray arm 33 to spray and clean the tableware in the inner tank 1; the specific steps of S3 are as follows: after the washing water in the water tank 2 is preheated, the water tank valve 6 is opened, the first washing pump 321 is shut down, and the preheated water in the water tank 2 flows to the water cup 31 for use; the specific steps of S4 are as follows: S41: the water tank valve 6 is opened and the water diversion valve 7 is closed; S42: the first washing pump 321 starts to transport the high-temperature washing waste water that flows back from the inner tank 1 to the water cup 31 into the water tank 2; S43: the water tank valve 6 is closed, waiting for the high-temperature washing waste water to release heat in the water tank 2, and using heat transfer to dry the tableware in the inner tank 1. When the water tank valve 6 is closed and the water diverter valve 7 is open, the first wash pump 321 operates to supply the wash water in the water cup 31 to the spray arm 33 for spraying. Simultaneously, the water tank 2 is filled with water through the water inlet assembly 4, allowing the wash water in the water tank 2 to absorb heat and preheat. When the wash water in the water tank 2 has been preheated to a preset temperature or for a preset time, the water tank valve 6 is opened and the first wash pump 321 is closed, allowing the preheated wash water to flow to the water cup 31 under the action of gravity for use. When the dishwasher is finished cleaning, the water tank valve 6 is opened and the water diverter valve 7 is closed. The first wash pump 321 operates to transfer the high-temperature wash water flowing from the inner tank 1 to the water cup 31 into the water tank 2 for storage, releasing heat and achieving the effect of drying the dishes. The coordination of the water tank valve 6, the water diverter valve 7, and the first wash pump 321 simplifies the structure of the water delivery assembly 32 and effectively controls the flow of wash water.

[0060] like Figure 9 As shown, in addition to the features of the above embodiment, this embodiment further defines: after step S4, the washing control method also includes: S5: after the drying is completed, the washing waste water in the water tank 2 is discharged to the outside of the dishwasher through the drainage component or flows back to the water cup 31 by opening the water tank valve 6 for the pre-washing step of the next washing.

[0061] like Figure 10As shown, in addition to the features of the above embodiments, this embodiment further defines: before step S2, the washing control method also includes: S1: the water inlet component 4 is started, and clean washing water is injected into the water tank 2 from an external water source, and the washing component 3 obtains washing water from the water tank 2.
