[0054] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or display that includes a series of steps or units does not necessarily limit to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0055] In the prior art, a dishwasher includes a washing pump and a heater. The washing pump is used to draw water into the interior of the inner tank to wash the tableware in the inner tank, and the heater is used to heat the water during the washing process to achieve high-temperature water washing. The power of the heater is relatively large, and most of the power consumption of the dishwasher is caused by the heater. The energy consumption of the dishwasher is relatively high.

[0056] After repeated thinking and verification, the inventor found that if a water tank is provided on the outer side of the inner tank of the dishwasher, and a semiconductor component is provided between the inner tank and the water tank, both sides of the semiconductor component are respectively attached to the inner tank and the water tank, and the semiconductor component is in thermal conduction with the inner tank and the water tank respectively. A battery is provided in the dishwasher, the semiconductor component is electrically connected to the battery, and the semiconductor component and the battery are respectively electrically connected to the control panel of the dishwasher. The working state of the semiconductor component can be determined according to the working state of the dishwasher. When there is a temperature difference between the inner tank and the water tank, the semiconductor component generates an electromotive force and charges the battery; when the dishwasher is drying or standing still, the battery can supply power to the semiconductor component. In this way, the heat generated by the heater can be fully utilized, improving the energy efficiency of the dishwasher. In addition, a pipeline system is connected between the water tank and the inner tank, and the water in the water tank can be reused, improving the water efficiency of the dishwasher.

[0057] In view of this, the inventor designed a control method and a dishwasher for a dishwasher. By providing a semiconductor component between the inner tank and the water tank, the semiconductor component is electrically connected to the battery and the control panel respectively. The control method first determines the working state of the dishwasher, and determines the working state of the semiconductor component according to the working state of the dishwasher. When the heat generated by the heater causes a temperature difference between the inner tank and the water tank, the semiconductor component can use the temperature difference to charge the battery. When the dishwasher is in other working states, the battery can charge the semiconductor component to make the semiconductor component refrigerate or heat. In addition, a pipeline system is provided between the inner tank and the water tank, and the water in the water tank can be reused. In this way, it is beneficial to improve the energy efficiency and water efficiency of the dishwasher.

[0058] The following describes in detail the technical solutions of the control method and the dishwasher for the dishwasher provided by the embodiments of the present application with reference to the accompanying drawings.

[0059] Refer to Figures 1 to 4 As shown, the control method for the dishwasher provided by the embodiments of the present application is applied to a dishwasher. The dishwasher includes an inner tank 100, a water tank 200, a semiconductor component 300, a battery 400, and a control panel 500. The water tank 200 is provided on the outer side of the inner tank 100, and a pipeline system is provided between the water tank 200 and the inner tank 100. Among them, the water in the water tank 200 can flow to the inner tank 100 through the pipeline system, and the water in the inner tank 100 can also flow to the water tank 200 through the pipeline system. In a possible implementation manner, after the water in the water tank 200 flows into the inner tank 100 and processes the tableware in the inner tank 100, it can also flow back to the water tank 200 through the pipeline system, that is, the water in the water tank 200 can be reused, which is beneficial to improving the water efficiency of the dishwasher.

[0060] One side of the semiconductor component 300 is attached to the outer wall of the inner tank 100 and conducts heat with the outer wall of the inner tank 100. The other side of the semiconductor component 300 is attached to the outer wall of the water tank 200 and conducts heat with the outer wall of the water tank 200. Schematically, the opposite sides of the semiconductor component 300 are respectively pressed against the outer wall of the inner tank 100 and the outer wall of the water tank 200. Thermal conductive silicone can be respectively arranged between the semiconductor component 300 and the inner tank 100 and between the semiconductor component 300 and the water tank 200 to increase the heat transfer efficiency between the semiconductor component 300 and the inner tank 100 and the water tank 200.

[0061] The battery 400 is electrically connected to the semiconductor component 300. Among them, the semiconductor component 300 can charge the battery 400 or be powered by the battery 400 in different working states. The control panel 500 is respectively electrically connected to the semiconductor component 300 and the battery 400. It can be understood that the control panel 500 can control the semiconductor component 300 and the battery 400.

[0062] Those skilled in the art can understand that semiconductor materials have the thermoelectric effect, which is specifically manifested as follows: When two different semiconductors are connected at both ends to form a circuit and there is a certain temperature difference on both sides of the semiconductor, an electromotive force will be generated in the semiconductor (Seebeck effect); When an electric current is passed through the circuit composed of two different semiconductors, heat absorption or heat release will occur on both sides of the semiconductor, and this phenomenon is reversible (Peltier effect). The thermoelectric effect can be used to realize the power generation and refrigeration / heating of the semiconductor component 300. The intensity of the thermoelectric effect of the semiconductor is related to the number of nodes. The semiconductor is composed of alternating N junctions and P junctions. The more the number of N-P nodes, the stronger the thermoelectric effect. The specific structure of the semiconductor component 300 is well known to those skilled in the art and is not uniquely limited here.

[0063] Such as Figure 3 and Figure 4 As shown, the control method of the dishwasher includes:

[0064] S110: Determine the working state of the dishwasher. The working states of the dishwasher include washing, drying, and standing still.

[0065] Specifically, the working state of the dishwasher can be controlled by the user operating the control panel 500, that is, the control panel 500 can obtain the working state of the dishwasher.

[0066] S120: Determine the working state of the semiconductor component 300 according to the working state of the dishwasher.

[0067] Specifically, the semiconductor component 300 has two working states. One is to generate an electromotive force using the temperature difference, and the other is to generate refrigeration or heating using external power supply. The working state of the semiconductor component 300 can be determined according to the external environment.

[0068] In this embodiment, a water tank 200 is arranged outside the inner tank 100 of the dishwasher, and a semiconductor component 300 is arranged between the inner tank 100 and the water tank 200. Both sides of the semiconductor component 300 are respectively attached to the inner tank 100 and the water tank 200, and the semiconductor component 300 is in thermal conduction with the outer wall of the inner tank 100 and the outer wall of the water tank 200 respectively. The dishwasher is also provided with a battery 400 and a control panel 500. The battery 400 is electrically connected to the semiconductor component 300, and the control panel 500 is electrically connected to the semiconductor component 300 and the battery 400 respectively. The control method of the dishwasher first determines the working state of the dishwasher, and then determines the working state of the attachment according to the working state of the dishwasher. In this way, the semiconductor component 300 can be charged and discharged in combination with different working states of the dishwasher, playing a role in saving energy consumption. And a pipeline system is arranged between the water tank 200 and the inner tank 100, and the water in the water tank 200 can be reused, improving the water efficiency of the dishwasher.

[0069] In one embodiment, as Figures 1 - 3 shown, when the dishwasher is in the washing state, there is a temperature difference between the inner tank 100 and the water tank 200, and the semiconductor component 300 uses the temperature difference to form an electromotive force and charges the battery 400.

[0070] Specifically, when the dishwasher is in the washing state, the water entering the inner tank 100 is heated by a heater and then sprayed onto the tableware in the inner tank 100 and the wall surface of the inner tank 100. The temperature of the inner tank 100 rises and is higher than the external environment, and heat is transferred from the inner tank 100 to the outside. Due to the large specific heat capacity of water, the temperature change of the water in the water tank 200 is relatively slow, and a large temperature difference is formed between the temperature of the inner tank 100 and the temperature of the water tank 200. The above temperature difference satisfies the conditions of the semiconductor Seebeck effect, and the semiconductor component 300 generates a thermoelectric electromotive force, and the battery 400 connected to the semiconductor component 300 continuously performs the charging work.

[0071] Optionally, a gap can be arranged between the inner tank 100 and the water tank 200, and the heat dissipated from the inner tank 100 is not easily transferred to the water tank 200, so as to further slow down the temperature change of the water in the water tank 200, ensure the temperature difference between the inner tank 100 and the water tank 200, and further ensure the charging efficiency of the semiconductor component 300 to the battery 400.

[0072] When the dishwasher is in the drying or static state, the semiconductor component 300 can generate a refrigerating or heating effect by using external power supply.

[0073] Specifically, the above refrigerating or heating effect is for the inner tank 100. When the semiconductor component 300 cools the inner tank 100, it heats the water tank 200 synchronously. When the semiconductor component 300 heats the inner tank 100, it cools the water tank 200 synchronously. By controlling the direction of the current flowing through the semiconductor component 300, the semiconductor component 300 can be controlled to cool or heat the inner tank 100.

[0074] When the relative humidity in the inner container 100 is relatively high and the semiconductor component 300 cools the inner container 100, condensed water is precipitated in the area where the high-humidity gas in the inner container 100 contacts the wall surface of the semiconductor component 300, which is beneficial to reducing the relative humidity in the inner container 100. When the semiconductor component 300 heats the inner container 100, it can promote the evaporation of the residual water attached to the wall surface of the inner container 100 and prevent the residual water attached to the wall surface of the inner container 100 from breeding bacteria.

[0075] With the above settings, when the dishwasher is in the washing state, the semiconductor component 300 uses the temperature difference between the inner container 100 and the water tank 200 to form an electromotive force to charge the battery 400, which is beneficial to the full utilization of energy and improves the energy efficiency of the dishwasher. When the dishwasher is in the drying or static state, the semiconductor component 300 cools or heats the inner container 100, which is beneficial to reducing the relative humidity in the inner container 100.

[0076] In a specific embodiment, as Figure 3 shown, when the dishwasher is in the drying state, the semiconductor component 300 is externally powered, the side of the semiconductor component 300 in contact with the inner container 100 cools down, and the side of the semiconductor component 300 in contact with the water tank 200 heats up.

[0077] Specifically, when the dishwasher is in the drying state, the inner container 100 is filled with high-humidity gas and needs to be dehumidified. The control panel 500 transmits a signal to the battery 400, and the battery 400 starts to actively discharge, providing an electromotive force to both sides of the semiconductor component 300. The Peltier effect is used to drive the electrons in the semiconductor component 300 to move from the side facing the inner container 100 to the side facing the water tank 200. The side of the semiconductor component 300 in contact with the inner container 100 serves as the cooling surface, and the temperature drops rapidly. A temperature difference appears between the side of the semiconductor component 300 in contact with the inner container 100 and the inner container 100, and the semiconductor component 300 absorbs heat from the inner container 100, thereby cooling the inner container 100. The area where the inner container 100 contacts the semiconductor component 300 contacts the high-humidity gas in the inner container 100, and condensed water is precipitated under the influence of low temperature, achieving the purpose of reducing the humidity of the gas in the inner container 100. At the same time, electrons gather on the water tank 200 side, and the heat of the semiconductor component 300 is transferred to the stored water in the water tank 200. The specific heat capacity of water is relatively high, and the water temperature in the water tank 200 changes slowly, and it can continuously absorb heat from the semiconductor to ensure that the semiconductor will not be damaged due to heat dissipation failure.

[0078] Exemplarily, as Figure 2As shown, a water tank 120 may be provided at the bottom of the inner tank 100. After the high-humidity gas in the inner tank 100 precipitates condensed water, the condensed water slides down under the action of gravity and finally flows into the water tank 120. The condensed water in the water tank 120 may also flow into the water tank 200 via the pipeline system to further improve the water efficiency of the dishwasher.

[0079] The above settings are beneficial to controlling the gas humidity in the inner tank 100 in the dry state of the dishwasher and are beneficial to improving the drying effect of the dishwasher.

[0080] In a specific embodiment, as Figure 1 and Figure 3 shown, a humidity sensor 110 is installed on the inner tank 100 to obtain the relative humidity in the inner tank 100. Exemplarily, the humidity sensor 110 may be installed on the side wall of the inner tank 100, and it can obtain the gas humidity in the inner tank 100. The humidity sensor 110 is electrically connected to the control panel 500, and then the control panel 500 can control the state of the semiconductor component 300 according to the gas humidity in the inner tank 100. The specific structure of the humidity sensor 110 in this embodiment is not limited, and those skilled in the art can select a suitable humidity sensor 110 according to actual needs or can also select an existing humidity sensor 110 on the market.

[0081] When the dishwasher is in a static state, when the relative humidity in the inner tank 100 reaches the first preset value, the semiconductor component 300 is positively powered, and the side of the semiconductor component 300 in contact with the inner tank 100 cools down, and the side of the semiconductor component 300 in contact with the water tank 200 heats up.

[0082] Among them, the specific size of the first preset value can be set as needed and is not uniquely limited here. When the relative humidity in the inner tank 100 reaches the first preset value, the semiconductor component 300 cools the inner tank 100, and the area of the inner tank 100 in contact with the semiconductor component 300 comes into contact with the high-humidity gas in the inner tank 100, and condensed water precipitates under the influence of low temperature, achieving the purpose of reducing the gas humidity in the inner tank 100.

[0083] When the relative humidity in the inner tank 100 drops from the first preset value to the second preset value, the semiconductor component 300 is reversely powered and lasts for a preset time. The side of the semiconductor component 300 in contact with the inner tank 100 heats up, and the side of the semiconductor component 300 in contact with the water tank 200 cools down.

[0084] Specifically, the second preset value is less than the first preset value. The specific magnitude of the second preset value can be set as required and is not uniquely defined herein. When the relative humidity in the inner container 100 drops from the first preset value to the second preset value, the semiconductor component 300 absorbs heat from the water tank 200 side and dissipates heat on the inner container 100 side, thereby heating the inner container 100, promoting the evaporation of the residual moisture on the wall surface of the inner container 100, lasting for a preset time T, and ultimately achieving the purpose of drying the wall surface of the inner container 100 to prevent the growth of bacteria due to the residual water on the wall surface.

[0085] The above settings enable the dishwasher to control the relative humidity in the inner container 100 in the static state, making it not easy for bacteria to grow in the inner container 100.

[0086] In a specific implementation manner, as Figure 3 shown, when the semiconductor component 300 is externally powered, the control panel 500 obtains the power of the battery 400. When the power of the battery 400 is higher than the preset percentage, the battery 400 supplies power to the semiconductor component 300. When the power of the battery 400 drops to the preset percentage, the control panel 500 supplies power to the semiconductor component 300.

[0087] Exemplarily, the above preset percentage can be 10%, 15% or 20% etc., and is not uniquely defined herein. As Figure 3 shown, taking the drying state of the dishwasher as an example, in the drying state of the dishwasher, the battery 400 is preferentially used to supply power to the semiconductor component 300. When the power of the battery 400 reaches the preset percentage, the control panel 500 of the dishwasher supplies power to the semiconductor component 300. It can be understood that in the static state of the dishwasher, the battery 400 is also preferentially used to supply power to the semiconductor component 300. When the power of the battery 400 reaches the preset percentage, the control panel 500 of the dishwasher supplies power to the semiconductor component 300.

[0088] The above settings are beneficial to ensuring the service life of the battery 400 and the reliability of the dishwasher.

[0089] In a possible implementation manner, the dishwasher further includes a thermostat 800. The thermostat 800 is configured to detect the temperature of the semiconductor component 300, and the thermostat 800 is electrically connected to the control panel 500. The control method further includes stopping supplying power to the semiconductor component 300 when the temperature of the semiconductor component 300 reaches the preset temperature.

[0090] Exemplarily, the thermostat 800 can be arranged above the semiconductor component 300, which can monitor the temperature condition of the semiconductor component 300 in real time and be used as a failure power-off measure. When the dishwasher is in the drying state or the static state, if the heat dissipation of the semiconductor component 300 fails and the temperature continuously rises to the preset temperature, the thermostat 800 cuts off the power emergently to protect the semiconductor component 300 from being damaged. That is to say, the above arrangement can ensure the service life of the semiconductor component 300 and the reliability of the dishwasher.

[0091] In one embodiment, as Figure 2 shown, the pipeline system includes a liquid inlet pipeline 600 and a liquid outlet pipeline 700. The liquid inlet pipeline 600 includes a liquid inlet pipe 610, a liquid inlet water distributor 620, a first connecting pipe 630 and a second connecting pipe 640. The liquid inlet pipe 610 includes a first liquid inlet branch pipe 612 and a second liquid inlet branch pipe 613. The liquid inlet pipe 610 further includes a liquid inlet main pipe 611, which is respectively connected to the first liquid inlet branch pipe 612 and the second liquid inlet branch pipe 613. A water inlet valve 614 and a flow meter 615 can be arranged on the liquid inlet main pipe 611. The water inlet valve 614 and the flow meter 615 cooperate to control the water inflow of the liquid inlet pipe 610.

[0092] The end of the first liquid inlet branch pipe 612 extends into the water tank 200. Among them, the end of the first liquid inlet branch pipe 612 extending into the water tank 200 can be located at the top of the water tank 200, so that there is a gap between the end of the first liquid inlet branch pipe 612 extending into the water tank 200 and the liquid level in the water tank 200, avoiding the water in the water tank 200 flowing out through the first liquid inlet branch pipe 612 and the liquid inlet main pipe 611 due to siphonage.

[0093] The end of the second liquid inlet branch pipe 613 is connected to the first port of the liquid inlet water distributor 620. The two ends of the first connecting pipe 630 are respectively connected to the second port of the liquid inlet water distributor 620 and the water tank 200. The two ends of the second connecting pipe 640 are respectively connected to the third port of the liquid inlet water distributor 620 and the inner tank 100. Exemplarily, a water tank 120 is arranged at the bottom of the inner tank 100, and the end of the second connecting pipe 640 far from the liquid inlet water distributor 620 can be connected to the water tank 120.

[0094] Schematically, the first port and the second port of the liquid inlet water distributor 620 are the two liquid inlet ends of the liquid inlet water distributor 620, and the third port of the liquid inlet water distributor 620 is the liquid outlet end of the liquid inlet water distributor 620. One of the second liquid inlet branch pipe 613 and the first connecting pipe 630 can be communicated with the second connecting pipe 640 through the liquid inlet water distributor 620, and the liquid inlet water distributor 620 can also control that neither the second liquid inlet branch pipe 613 nor the first connecting pipe 630 is communicated with the second connecting pipe 640. The liquid inlet water distributor 620 can be electrically connected to the control panel 500, and further the control panel 500 can control the state of the liquid inlet water distributor 620.

[0095] The liquid outlet pipeline 700 includes a liquid outlet main pipe 710, a first liquid outlet branch pipe 720, a second liquid outlet branch pipe 730, and a liquid outlet water distributor 740. Two ends of the liquid outlet main pipe 710 are respectively connected to the inner tank 100 and a first port of the liquid outlet water distributor 740. Two ends of the first liquid outlet branch pipe 720 are respectively connected to a second port of the liquid outlet water distributor 740 and the water tank 200. The second liquid outlet branch pipe 730 is connected to a third port of the liquid outlet water distributor 740.

[0096] Schematically, the first port of the liquid outlet water distributor 740 is the liquid inlet end of the liquid outlet water distributor 740, and the second port and the third port of the liquid outlet water distributor 740 are respectively two liquid outlet ends of the liquid outlet water distributor 740. The liquid outlet main pipe 710 can communicate with one of the first liquid outlet branch pipe 720 and the second liquid outlet branch pipe 730 through the liquid outlet water distributor 740, and the liquid outlet water distributor 740 can also control that neither the first liquid outlet branch pipe 720 nor the second liquid outlet branch pipe 730 communicates with the liquid outlet main pipe 710. The liquid outlet water distributor 740 can be electrically connected to the control panel 500, and further the control panel 500 can control the state of the liquid outlet water distributor 740. The liquid inlet water distributor 620 and the liquid outlet water distributor 740 cooperate to work, and the flow of water between the inner tank 100 and the water tank 200 can be controlled by controlling the states of the liquid inlet water distributor 620 and the liquid outlet water distributor 740.

[0097] The control method further includes:

[0098] When the dishwasher is in the washing state, the inner tank 100 is preferentially supplied with water by the water tank 200 through the first connecting pipe 630, the liquid inlet water distributor 620, and the second connecting pipe 640. After the water tank 200 is emptied, the inner tank 100 is supplied with water by the second liquid inlet branch pipe 613, the liquid inlet water distributor 620, and the second connecting pipe 640, and the water tank 200 is replenished with water by the first liquid inlet branch pipe 612.

[0099] Specifically, at the beginning of the washing state of the dishwasher, the water in the water tank 200 flows into the inner tank 100, the liquid inlet water distributor 620 connects the water tank 200 and the inner tank 100. After the water tank 200 is emptied, the liquid inlet water distributor 620 connects the inner tank 100 and the second liquid inlet branch pipe 613, the water inlet valve 614 is opened, and an external water source is provided to the inner tank 100 through the water inlet pipe 610. The water inflow is controlled by the flow meter 615, and the water inlet valve 614 is closed after the water inlet is completed. After the water inlet of the inner tank 100 ends, the inner tank 100 replenishes water to the water tank 200 through the water inlet pipe 610 and the water inlet main pipe 611.

[0100] After the dishwasher ends the washing state, the water in the inner tank 100 is discharged externally through the liquid outlet main pipe 710, the liquid outlet water distributor 740, and the second liquid outlet branch pipe 730.

[0101] Specifically, after the dishwasher finishes the washing state, the washing water is sewage and needs to be discharged. The liquid outlet water distributor 740 controls the water discharged by the liquid outlet pump 750 to be discharged externally through the second liquid outlet branch pipe 730.

[0102] With the above settings, the water in the water tank 200 is used for washing, avoiding the growth of bacteria due to the long-term storage of the water in the water tank 200.

[0103] In a specific embodiment, as Figure 2 and Figure 3 shown, the working state of the dishwasher further includes cold rinsing. Among them, during the cleaning process of the dishwasher, the cold rinsing state is located between the washing state and the drying state.

[0104] When the dishwasher is in the cold rinsing state, the water in the water tank 200 flows into the inner tank 100 through the first connecting pipe 630, the liquid inlet water distributor 620, and the second connecting pipe 640. Exemplarily, when the dishwasher is in the cold rinsing state, the water in the water tank 200 flows into the water tank 120 at the bottom of the inner tank 100 through the first connecting pipe 630, the liquid inlet water distributor 620, and the second connecting pipe 640 to perform cold rinsing on the tableware in the inner tank 100.

[0105] After the dishwasher finishes the cold rinsing state, the water in the inner tank 100 flows towards the water tank 200 through the liquid outlet main pipe 710, the liquid outlet water distributor 740, and the first liquid outlet branch pipe 720.

[0106] It can be understood that when the dishwasher is in the cold rinsing state and after finishing the cold rinsing state, the water in the water tank 200 circulates between the water tank 200 and the inner tank 100, realizing the reuse of the water in the water tank 200. After the dishwasher finishes the cold rinsing state, the water in the water tank 200 can be used as the pre-washing water for the next wash, effectively reducing the periodic water consumption of the dishwasher and improving the water efficiency. In the drying state after the cold rinsing state of the dishwasher, the water in the water tank 200 is cold rinsing water, which is normal temperature water and is used for the heat dissipation of the semiconductor component 300 and is not discharged after the drying state ends. When the water tank 200 is in the storage state, the water in the water tank 200 serves as the heat dissipation / cooling end medium and can maintain a relatively stable temperature.

[0107] In a possible implementation manner, the working state of the dishwasher further includes hot rinsing. During the cleaning process of the dishwasher, the hot rinsing state is located between the cold rinsing state and the drying state. When the dishwasher is in the hot rinsing state, the liquid inlet water distributor 620 connects the second connecting pipe 640 with the second liquid inlet branch pipe 613, and supplies water to the inner tank 100 through the liquid inlet pipe 610; after the dishwasher finishes the hot rinsing state, the liquid outlet water distributor 740 connects the liquid outlet main pipe 710 with the second liquid outlet branch pipe 730, and the hot rinsing water in the inner tank 100 is discharged externally through the liquid outlet main pipe 710, the liquid outlet water distributor 740, and the second liquid outlet branch pipe 730.

[0108] As Figure 1 andFigure 2 As shown, the present application also provides a dishwasher, which includes an inner tank 100, a water tank 200, a semiconductor component 300, a battery 400, and a control panel 500. The water tank 200 is arranged outside the inner tank 100, and a pipeline system is arranged between the water tank 200 and the inner tank 100. One side of the semiconductor component 300 is attached to the outer wall of the inner tank 100 and conducts heat with the outer wall of the inner tank 100, and the other side of the semiconductor component 300 is attached to the outer wall of the water tank 200 and conducts heat with the outer wall of the water tank 200. The battery 400 is electrically connected to the semiconductor component 300. The control panel 500 is electrically connected to the semiconductor component 300 and the battery 400 respectively. The control panel 500 controls the operation of the dishwasher by using the above control method.

[0109] For the dishwasher provided by the present application, the semiconductor component 300 can be charged and discharged in combination with different working states of the dishwasher, playing a role in saving energy consumption. And a pipeline system is arranged between the water tank 200 and the inner tank 100, and the water in the water tank 200 can be reused, improving the water efficiency of the dishwasher.

[0110] In a possible implementation manner, the part of the water tank 200 in contact with the semiconductor component 300 is made of a metal material, and the part of the water tank 200 located outside the semiconductor component 300 is made of a non-metal material.

[0111] Exemplarily, the part of the water tank 200 in contact with the semiconductor is made of a stainless steel sheet, and the rest of the water tank 200 can be made of plastic. As Figure 2 shown, the part of the water tank 200 in contact with the semiconductor component 300 forms a contact area 210 on the side wall of the water tank 200. The part of the water tank 200 in contact with the semiconductor component 300 being made of a metal material can ensure the heat transfer efficiency between the water tank 200 and the semiconductor component 300. Optionally, the water tank 200 can be formed into an integral part through an integral molding process to achieve the sealing between the metal part and the non-metal part of the water tank 200.

[0112] The water tank 200 covers the side of the inner tank 100. Exemplarily, the water tank 200 can be an approximate plate-like structure, and the part of the water tank 200 located outside the semiconductor component 300 can be attached to the side of the inner tank 100 and cover the side of the inner tank 100. The part of the water tank 200 located outside the semiconductor component 300 can be made of a low thermal conductivity polymer plastic.

[0113] When the dishwasher is in the washing state, the inner tank 100 dissipates heat outward as a whole. In this embodiment, the water tank 200 can effectively prevent the heat of the inner tank 100 from escaping when the dishwasher is in the washing state, keep the environment of the inner tank 100 at a high temperature state, improve the thermal energy utilization rate, and further improve the energy efficiency of the dishwasher.

[0114] In a specific embodiment, there is a gap between the top end of the semiconductor component 300 and the top end of the water tank 200.

[0115] Schematically, the semiconductor component 300 can be located near the middle of the inner tank 100, and the overall height of the water tank 200 is higher than that of the semiconductor component 300. When the semiconductor component 300 transfers heat to the water tank 200, the water near the contact area 210 between the water tank 200 and the semiconductor component 300 is heated and its temperature rises, the density decreases, and it begins to float upward, pushing the water in the water tank 200 to circulate. After being heated, it flows to the other side for heat dissipation, ensuring that the water temperature in the water tank 200 remains relatively stable.

[0116] With the above arrangement, the water temperature in the water tank 200 changes slowly, and stable heat transfer can be achieved between the water tank 200 and the semiconductor, maintaining the stable operation of the semiconductor component 300.

[0117] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
