The working principle of the dishwasher is as follows: a washing pump in the dish washer sprays washing water dissolved with detergent to the tableware to be washed at a high speed, and the washing water washes the tableware for multiple times and is discharged; then the washing pump extracts clean water to wash the tableware, and after the tableware is washed clean, a heating element in the dish washing machine heats the air in the washing cavity, so that the tableware is dried.

In order to improve the cleaning effect of the dish washing machine, the dish washing machine can also carry out sterilization and disinfection treatment on tableware, and the current commonly used sterilization and disinfection modes comprise high-temperature sterilization, ozone sterilization, ultraviolet sterilization and the like.

High temperature sterilization is a common sterilization method, and the principle is that a heating element is arranged in the dishwasher, and the heating element can heat the air in the washing cavity. The tableware is placed in the washing cavity, and microorganisms on the tableware can be killed by the high-temperature environment in the washing cavity.

Ozone is a common oxidizing bactericide, and ozone sterilization is to destroy the structure of a microbial film by using the oxidation of oxygen atoms in ozone, so that the tableware can be sterilized. Ozone is generally explosive and special in taste, and the human body inhales too much ozone which is harmful to health, so that a door of the dishwasher cannot be opened immediately after the dishwasher is sterilized by ozone, and the door needs to be opened after the ozone is decomposed for a period of time.

Ultraviolet sterilization is to use ultraviolet rays with a wavelength ranging from 240nm to 280nm to destroy the molecular structure of Deoxyribonucleic Acid (DNA) or Ribonucleic Acid (RNA) in bacterial viruses, and especially ultraviolet rays with a wavelength of about 253.7nm have a better destruction effect on the bacterial viruses, so that growing cells and/or regenerative cells are killed, and the sterilization and disinfection effects on tableware are achieved.

The ultraviolet sterilization belongs to a purely physical sterilization and disinfection method, and has the advantages of simplicity, rapidness, high sterilization efficiency, no secondary pollution, convenience in control, realization of automation and the like. But the ultraviolet rays have weak penetrating power and cannot penetrate most of transparent glass and plastics.

The current dish washer that has ultraviolet sterilization function generally can be at the roof or the side wall mounting ultraviolet lamp subassembly in washing chamber, and this ultraviolet lamp subassembly passes through joint or threaded connection's mode to be connected on the roof or the side wall in washing chamber, and these connected mode later stages dismouting maintenance are comparatively inconvenient. Moreover, due to the long-term high-temperature washing operation of the dish washing machine, the clamping structure or the threads of the ultraviolet lamp assembly are easy to loosen and leak steam, so that the service life of the dish washing machine is shortened. When the bowl basket or the tableware is taken and placed, the bowl basket or the tableware is easy to collide with the ultraviolet lamp assembly, and then the ultraviolet lamp assembly is damaged.

In addition, because the tableware in the washing cavity is generally stacked, when the ultraviolet light irradiates the tableware, a blind area which cannot be irradiated by the ultraviolet light inevitably appears on the tableware, so that the tableware is not completely sterilized, and the sterilizing effect is poor.

Based on this, as shown in fig. 1, fig. 1 is a schematic view of an overall structure of the dishwasher provided in the embodiment of the present application, and the dishwasher 100 may include an inner container 1, a door 2, and a base 3.

The inner container 1 forms a washing cavity 11 inside, and the washing cavity 11 can be used for placing tableware to be washed. The door 2 can be rotatably connected with the inner container 1 for opening and closing the washing chamber 11. The base 3 is arranged on one side of the inner container 1. As shown in fig. 1, the base 3 is disposed below the inner container 1. In addition, the dishwasher 100 may further include a casing (not shown), which may be disposed outside the inner container 1 and may protect the inner container 1.

As shown in fig. 2, fig. 2 is a schematic view of an overall structure of the washing system 4 and the sterilization device 5 according to the embodiment of the present application, and the dishwasher 100 may further include the washing system 4 and the sterilization device 5. The washing system 4 is formed with a washing flow path, both ends of which are respectively communicated with the washing chamber 11 (fig. 1). Thereby, the washing water can circulate in the washing flow path to wash the dishes.

As shown in fig. 1, the inner container 1 includes a bottom plate 12, and the bottom plate 12 may be connected to the base 3. In order to connect the two ends of the washing flow path with the washing chamber, a water outlet 121 and a water inlet (not shown) are provided on the bottom plate 12, the washing system 4 (fig. 2) can be disposed in the base 3, and the two ends of the washing flow path are connected with the washing chamber 11 through the water outlet 121 and the water inlet, respectively.

Referring to fig. 2, a sterilizing device 5 is connected in the washing flow path, and includes a sterilizing lamp (not shown in fig. 2) for emitting ultraviolet light toward the washing flow path to sterilize and disinfect the washing water in the washing flow path.

Because the sterilizing device is arranged in the washing flow path, when the washing water in the washing flow path passes through the sterilizing device, the ultraviolet light emitted by the sterilizing lamp can sterilize and disinfect the washing water in the washing flow path. Therefore, when the washing water sterilized and disinfected by the sterilizing device is used for cleaning tableware, the tableware can be comprehensively sterilized, and the sterilizing effect of the dish washing machine is good.

With continued reference to fig. 2, the washing system 4 may include a circulation pump 41 and a reservoir 42. Wherein one end of the circulation pump 41 is communicated with the washing chamber 11 (fig. 1), and the other end is connected with one end of the sterilization device 5.

The liquid storage box 42 includes a bottom wall 421 and a side wall 422 disposed around the bottom wall 421, a liquid storage tank 423 having a water collection opening is enclosed by the bottom wall 421 and the side wall 422, the water collection opening is communicated with the water discharge opening 12 (fig. 1), the side wall 422 is provided with a water delivery opening (not shown in the figure) communicated with the liquid storage tank 423, and the water delivery opening is communicated with the other end of the sterilization device 5.

When the dishwasher 100 washes dishes, the washing water in the reservoir 423 flows into the sterilization device 5 from the water inlet under the action of the circulation pump 41 for sterilization and disinfection, and the washing water after sterilization and disinfection flows into the circulation pump 41 and flows into the washing chamber 11 under the action of the circulation pump 41 to wash the dishes in the washing chamber 11. The washing water after washing enters the reservoir 423 through the drain port 121, thereby completing one washing cycle. In the washing process, the tableware can be thoroughly washed through a plurality of washing cycles of the circulating pump 41, so that the washing effect of the tableware is better, and the water consumption of the washing machine in the washing process is greatly reduced.

It is understood that, in order to introduce external water into the dishwasher 100, in some embodiments, the reservoir 42 may further include a water inlet 424 in communication with the reservoir 423, and the dishwasher 100 may further include a water inlet pipe (not shown) having one end in communication with the water inlet 424 and the other end in communication with an external waterway system. In this way, water in the external waterway may be introduced into the reservoir 42 through the inlet 424 via the inlet line, which may satisfy the water demand of the dishwasher 100.

In order to spray the dishes in the washing chamber 11 more completely, as shown in fig. 3, fig. 3 is a schematic view of the overall structure of fig. 2 when the spray seat 43 is connected with the spray arm 44, in some embodiments, the dishwasher 100 may further include the spray seat 43 and the spray arm 44, and the spray seat 43 may be disposed in the base 3 (fig. 1) and connected with the circulation pump 41. Spray arm 44 may be located within wash chamber 11 (fig. 1) and connected to spray seat 43 via a water inlet. The spray seat 43 can distribute the washing water, and the spray arm 44 can spray the washing water onto the dishes to clean the dishes better.

As shown in fig. 3, spray arms 44 may include a bottom spray arm 441 and a top spray arm 442. Thus, the tableware can be cleaned in all directions through the bottom spraying arm 441 and the top spraying arm 442, and the cleaning effect of the dishwasher is improved.

In some embodiments, in order to heat the washing water, the dishwasher may further include a heating device (not shown) connected in the washing flow path for heating the washing water in the washing flow path. For example, the heating device may be a heating sheet integrally provided in the circulation pump 41.

In some embodiments, in order to detect the temperature of the washing water, the dishwasher 100 may further include a temperature sensor (not shown in the drawings) connected in the washing flow path for detecting the temperature of the washing water in the washing flow path.

In some embodiments, the dishwasher 100 may further include a breather (not shown) and a water softener (not shown) connected to the water inlet line, the water softener being configured to adsorb calcium, magnesium, and the like from the water to soften the water entering the reservoir 423, the softened water reducing the probability of scale formation. The respirators communicate with the washing chamber 11 and the outside, respectively, to equalize the pressure of the washing chamber 11 with the outside atmosphere.

In order to prevent food residues washed from the dishes from entering the washing flow path, in some embodiments, the washing system 4 may further include a filter screen (not shown) located at the water inlet of the storage box 42, so that the food residues washed from the dishes can be isolated in the reservoir 423 by the filter screen, thereby effectively preventing the food residues from entering the sterilization device 5 and prolonging the service life of the sterilization device 5.

In order to realize the circulation of the washing water in the sterilization device 5, referring to fig. 4, fig. 4 is an exploded view of the sterilization device 5 according to an embodiment of the present disclosure, in some embodiments, the sterilization device 5 may further include a device body 52, a circulation channel 521 is formed inside the device body 52, one end of the device body 52 is formed with a first circulation port, and the other end is formed with a second circulation port. The first circulation port communicates with a water supply port of the reservoir 42 (fig. 3), and the second circulation port is connected to one end of the circulation pump 41 (fig. 3). The germicidal lamp 51 is connected to the apparatus body 52 for emitting ultraviolet light into the flow path 521 (the connected state of the germicidal lamp 51 to the apparatus body 52 can be seen in fig. 2).

The washing water flowing out from the water supply port of the reservoir 42 can flow into the flow path 521 through the first flow port of the apparatus main body 52, and the germicidal lamp 51 connected to the apparatus main body 52 can sterilize the washing water flowing into the flow path 521. The sterilized washing water flows out from the second circulation port of the apparatus main body 52 and is then sprayed into the washing chamber 11 by the circulation pump 41.

In this way, by providing the device main body 52 and connecting the germicidal lamp 51 to the device main body 52, the washing water can be circulated in the germicidal device 5, and further, the washing water circulated in the germicidal device 5 can be sterilized and disinfected.

The shape of the device body 52 may vary, and the device body 52 may be cylindrical, for example.

In order to facilitate communication between the circulation passage 521 and the circulation pump 41 and the reservoir 42 in the apparatus main body 52, the cross-sectional shape of the circulation passage 521 may be circular. Of course, the cross-sectional shape of the flow channel 521 may be other shapes depending on the actual use requirements of the flow channel 521.

In some embodiments, the dishwasher 100 may further include a pipe clamp (not shown), by which the device body 52 can be more conveniently communicated with the circulation pump 41 and the reservoir 42.

With continued reference to fig. 4, in some embodiments, the device body 52 is provided with a light outlet 522 communicating with the flow channel 521, and the germicidal lamp 51 is disposed at the light outlet 522 and emits ultraviolet light into the flow channel 521 through the light outlet 522, that is, as shown in fig. 2, a part of the germicidal lamp 51 extends into the flow channel 521 through the light outlet 522 (fig. 4). Thus, the ultraviolet light emitted from the germicidal lamp 51 can be easily emitted into the flow channel 521 through the light-emitting hole 522, and the water in the flow channel 521 can be sterilized and disinfected.

In order to sterilize the washing water in the circulation passage 521 in a plurality of directions, in some embodiments, the number of the light emitting holes 522 and the germicidal lamps 51 is plural, the light emitting holes 522 are spaced apart along the circumference of the apparatus body 52, and each germicidal lamp 51 is located at one light emitting hole 522.

In this way, the ultraviolet light emitted from the plurality of germicidal lamps 51 is incident into the flow channel 521 through the plurality of light emitting holes 522, so that the washing water in the flow channel 521 can be sterilized in a plurality of directions, and the sterilizing effect of the washing water is improved.

The number of the light emitting holes 522 and the germicidal lamps 51 is not limited herein, and the number of the light emitting holes 522 and the germicidal lamps 51 is four, for example.

Referring to fig. 9, fig. 9 is a cross-sectional view of the sterilization device 5 according to the embodiment of the present application, in which the sealing member 53 is sandwiched between the mounting portion 5111 and the connecting portion 524.

Through setting up sealing member 53, because sealing member 53 and waterproof cover 513, the installation department 5111 of fixing base 511 and the connecting portion 524 of device main part 52 all support and lean on, this sealing member 53 has not only played the sealed effect outside the junction of waterproof cover 513 with fixing base 511 like this, it enters into inside waterproof cover 513 to have further avoided the washing water from the junction of waterproof cover 513 with fixing base 511, still played the sealed effect between fixing base 511 and device main part 52, further avoided the washing water to follow light-emitting hole 522 and flow out.

In order to ensure the sealing effect of the sealing member 53, the outer shape of the waterproof case 513 may be circular, and the sealing member 53 may also be circular.

The sealing member 53 may be made of a rubber material having a certain elasticity, so that the waterproof effect of the sealing member 53 can be further improved.

In order to further improve the sealing effect between the fixing seat 511 and the device main body 52, referring to fig. 10, fig. 10 is a partial structural schematic diagram of the sterilization device 5 provided in the embodiment of the present application, a placing groove 526 is opened on the connecting portion 524, the placing groove 526 is disposed around the avoiding hole 5241, and the sealing member 53 is located in the placing groove 526 and abuts against the groove bottom of the placing groove 526.

Thus, when the fixing base 511 is mounted on the device body 52, the sealing member 53 abuts not only the lower surface and the groove bottom of the mounting portion 5111 of the fixing base 511, but also the connecting portion 524 of the device body 52 outside the placement groove 526, so that the sealing effect between the fixing base 511 and the device body 52 is improved.

In order to control the dishwasher, as shown in fig. 11, fig. 11 is a circuit architecture diagram of the dishwasher provided in the embodiment of the present application, the dishwasher may further include a controller 6, and the controller 6 refers to a device that can generate an operation control signal according to an instruction operation code and a timing signal, and instruct the dishwasher to execute a control instruction. Illustratively, the controller 6 may be a Central Processing Unit (CPU), a general purpose processor Network Processor (NP), a Digital Signal Processor (DSP), a Programmable Logic Device (PLD), a microprocessor, a microcontroller, or any combination thereof. The controller 6 may also be other devices with processing functions, such as a circuit, a device, or a software module, which is not limited in any way by the embodiments of the present application.

For example, after the user selects and starts the drying program, the controller 6 can control the operation of the electrical components, and the tableware in the washing liner meets the user's requirements.

As shown in fig. 11, the dishwasher includes a pressure sensor 71, a turbidity sensor 72, a drain pump 73, a shunt valve 74, a power supply 75, and a display 76. Among them, the pressure sensor 71, the turbidity sensor 72, the drain pump 73, the water diversion valve 74, the power supply 75, the display 76, the temperature sensor 77, the heating device 78, and the sterilization device 5 are electrically connected to the controller 6.

The pressure sensor 71 can be used to detect the pressure inside the inner container and maintain the pressure inside the inner container in a balanced state. The turbidity sensor 72 may be provided in the washing flow path, and may detect the turbidity level of the washing water, and determine whether the washing water is reused or discharged.

The drain pump 73 may be used to drain the washing water, and the shunt valve 74 may distribute the flow of the washing water to various locations. For example, the shunt valve 74 may be provided at the spray seat 43, and the washing water is flowed toward the bottom spray arm 441 or the top spray arm 442 by opening and closing the shunt valve 74.

The display 76 may be used to display a control panel of a washing machine or dishwasher operational information. For example, the dishwasher may display information on the operational state, operational duration, etc. of the dishwasher through the display 76. The user may also control the dishwasher via the display 76.

Referring to fig. 12, fig. 12 is a first flowchart illustrating a method for controlling a dishwasher according to an embodiment of the present application, where the method includes steps.

S100: the controller controls the dishwasher to operate a washing program.

Wherein, the washing program can be set by the user before starting the washing program. For example, a user may select a washing mode of the dishwasher by operating on a display on the dishwasher. The washing time and the washing temperature of the washing process may be different according to the selected washing mode.

S200: if the washing program includes a sterilization step, the controller controls the sterilization device to be turned on.

When the washing program comprises a sterilization step, the controller can control the sterilization device to be opened in the running process of the washing program to sterilize and disinfect the washing water, and the sterilized and disinfected washing water cleans the tableware, so that the tableware is sterilized and disinfected. In the washing process, the washing water can comprehensively clean the tableware, so that the sterilization and disinfection effects of the dish washing machine are ensured.

In some embodiments, the washing program of the dishwasher may include a washing program and a rinsing program. Wherein, the cleaning procedure is mainly responsible for cleaning most of the stains carried on the tableware. In this process, the dish washer washes dishes with washing water to which a detergent is added, and washes off oil stains and the like on the dishes. The rinsing procedure is mainly responsible for washing away residual detergent on the tableware and carrying out secondary washing.

Therefore, as shown in fig. 13, fig. 13 is a second flowchart of the control method of the dishwasher according to the embodiment of the present application, and the step S110 of controlling the dishwasher to run the washing program by the controller is included.

S110: the controller controls the dishwasher to sequentially run a washing program and a rinsing program.

Thus, when the controller controls the dishwasher to perform a washing program, the dishwasher washes the dishes with the washing water to which the detergent is added, and cleans up the stains and the like on the dishes. When the controller controls the dish washer to carry out a cleaning program, the tableware is rinsed by using clean water, and the detergent left on the tableware in the cleaning program process is washed clean, so that no residual stain is left on the surface of the tableware.

If the washing program includes the sterilization step, the controller controls the sterilization device to be turned on including step S210.

S210: and controlling the sterilizing device to be opened when the washing program carries out the rinsing program.

As can be seen from the above, the cleaning stage is mainly responsible for removing stains such as oil stains from the dishes, and is mainly responsible for cleaning the dishes. At this time, if the sterilizing apparatus is turned on to sterilize the dishes, the washing water is turbid, and a good sterilizing effect cannot be obtained. Therefore, the tableware can be sterilized without opening the sterilizing device at this stage. After the main oil stain of the tableware is cleaned, the tableware is sterilized after entering a rinsing program, the sterilization effect of the dish washing machine can be ensured, and the electric energy effect of the dish washing machine can be reduced.

In some embodiments, as shown in fig. 14, fig. 14 is a third flowchart illustrating a control method of a dishwasher according to an embodiment of the present application, and the step of controlling the dishwasher to sequentially run a washing program and a rinsing program by the controller further includes steps S111 to S112.

S111: if the running time of the washing program is less than or equal to the preset washing time, after the washing program enters the cleaning program, the controller acquires the temperature of the washing water detected by the temperature sensor and controls the heating device to heat the washing water to the first cleaning temperature.

S112: if the running time of the washing program is longer than the preset washing time, after the washing program enters the washing program, the controller acquires the temperature of the washing water detected by the temperature sensor and controls the heating device to heat the washing water to the second washing temperature.

Wherein the second cleaning temperature is higher than the first cleaning temperature. The re-washing stage may have a longer time to heat the washing water to a higher second washing temperature due to a longer operation time of the washing program. Therefore, the oil stain on the tableware can be better dissolved, and the cleaning efficiency of the dish washing machine is improved.

Illustratively, the first cleaning temperature may be from 45 ℃ to 50 ℃. For example, the first cleaning temperature may be 45 ℃, 48 ℃, or 50 ℃, and the second cleaning temperature may be 5 ℃ higher than the first cleaning temperature. When the first cleaning temperature and the second cleaning temperature are within the above range, the stains on the tableware can be better cleaned, and simultaneously, the heating time can be prevented from being too long, and more washing time can be distributed.

It is understood that the preset washing time may be selected according to actual circumstances. For example, the preset washing time may be 60min.

In some embodiments, the rinsing program may include a cold rinsing program and a hot rinsing program that are performed sequentially.

In the cold rinsing procedure, the dishwasher mainly rinses the tableware by using clean water with lower temperature, and is mainly responsible for washing off the washing water with detergent remained on the tableware in the washing procedure, so that no detergent remains on the tableware. In the hot procedure that floats, dish washer mainly utilizes the higher washing of temperature to carry out the rinsing again to the tableware, utilizes the higher condition of hot temperature that floats simultaneously, promotes the temperature on tableware surface, and then makes things convenient for follow-up stoving procedure, makes things convenient for the stoving of tableware.

As shown in fig. 15, fig. 15 is a fourth flowchart illustrating a control method of a dishwasher according to an embodiment of the present application, in which the controller controls the dishwashers to sequentially run a washing program and a rinsing program including steps S121 to S124.

S121: and if the running time of the washing program is less than or equal to the preset washing time, the controller controls the running time of the hot bleaching program to be the first hot bleaching time.

S122: after the washing program enters the hot rinsing program, the controller acquires the temperature of the washing water detected by the temperature sensor and controls the heating device to heat the washing water to the first rinsing temperature.

S123: and if the running time of the washing program is greater than the preset washing time, the controller controls the running time of the hot rinsing program to be a second hot rinsing time.

S124: after the washing program enters the hot rinsing program, the controller acquires the temperature of the washing water detected by the temperature sensor, and the controller controls the heating device to heat the washing water to a second rinsing temperature.

Wherein the second rinsing temperature is higher than the first rinsing temperature, and the second hot rinsing time is longer than or equal to the hot rinsing time.

Since the temperature sensor can detect the temperature of the washing water. Therefore, after the washing program enters the hot rinsing program, the controller can grasp the temperature condition of the washing water in real time through the information transmitted by the temperature sensor.

Since the heating device can heat the washing water, the heating device is controlled by the controller to heat the washing water. Meanwhile, the controller can control the temperature condition of the washing water through the temperature sensor, and when the washing water is heated to the first rinsing temperature or the second rinsing temperature, the controller can control the heating device to be turned off.

Similarly, when the washing time is greater than the preset time, the washing time is longer. At this time, the time of the hot rinsing process may be a second hot rinsing time, and the rinsing temperature may be a second rinsing temperature. Therefore, the tableware can be better cleaned, and the preparation is made for subsequent drying. Meanwhile, since the second rinsing temperature is high, a part of microorganisms on the dishes can be killed by using high temperature.

Before executing the washing program, the running time of the washing program and the running time of the hot float can be correspondingly executed by the controller in a mode selected by the user. The running time of the hot-bleaching program is longer when the running time of the washing program selected by the user is longer, and the running time of the hot-bleaching program is shorter when the running time of the washing program selected by the user is shorter.

In some embodiments, as shown in fig. 16, fig. 16 is a flowchart illustrating a fifth flowchart of a control method of a dishwasher according to an embodiment of the present application, where the step S211 to S212 is included when the controller controls the sterilization device to open after the washing program enters the hot-rinsing program.

S211: if the temperature of the washing water is higher than the preset temperature, the controller controls the sterilizing device to be in a closed state.

S212: if the temperature of the washing water is less than or equal to the preset temperature, the controller controls the sterilizing device to be in an open state.

When the temperature of the washing water is high, the high-temperature washing water can perform a high-temperature sterilization effect on the tableware. At this time, the washing water with higher temperature can have better sterilization effect on the tableware.

Therefore, when the temperature of the washing water is higher than the preset temperature, the controller can control the sterilization device to be closed, and the tableware is sterilized by the high-temperature washing water. When the temperature of the washing water is less than or equal to the preset temperature, the controller can control the sterilization device to be opened, the sterilization device is used for sterilizing the washing water, and then the sterilized washing water is used for sterilizing and disinfecting the tableware, so that a better sterilization effect is ensured. Therefore, the sterilizing device can be selectively opened and closed, so that the opening time of the sterilizing device in the washing process can be shortened, and the electric energy effect is reduced on the premise of ensuring the sterilizing effect.

In some embodiments, the preset temperature may be 60 ℃. When the temperature of the washing water is more than 60 ℃, the washing water has a good high-temperature sterilization effect and can perform a good sterilization effect on tableware. In this case, the tableware can be effectively used without using a sterilizer.

When the temperature of the washing water is less than or equal to 60 ℃, the washing water needs to be disinfected by a disinfection device, and then the disinfected washing water is used for disinfecting and sterilizing the surface of the tableware, so that the tableware is disinfected.

In some embodiments, the difference between the first heat bleaching time and the second heat bleaching time may be 5min to 10min. When the running time of the washing program is longer, the hot bleaching time of the tableware can be prolonged, so that the temperature of the surface of the tableware can be fully raised, the surface of the tableware can be raised to a higher temperature, and the subsequent drying effect is facilitated. When the difference is within the above range, a good rinsing effect can be provided to the tableware. When the difference time is too long, the washing time of the tableware is reduced, and the washing effect is affected.

In some embodiments, the difference between the second rinse temperature and the first rinse temperature may be from 5 ℃ to 10 ℃. When the difference falls within the above range, the tableware can be heated to the second rinsing temperature for a sufficient time to rinse the tableware at a higher temperature when the washing time is longer. When the difference is more than the above range, the heating time is increased, thereby making the rinsing time less.

In some embodiments, the washing program may further include a pre-washing program, wherein the dishes are washed with cold water to wash away the easily re-soiled dishes during the washing program. And then, carrying out a cleaning program, and cleaning the tableware by using the heated washing water to wash away the stains which are not easy to clean on the tableware.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
