Description

Technical Field

[0001] This invention relates to the field of dishwashers, and specifically provides a method for controlling a dishwasher. Background Technology

[0002] A dishwasher is a device used to automatically clean tableware such as bowls, chopsticks, plates, dishes, knives, and forks. To enhance the cleaning effect, existing dishwashers typically use ultraviolet (UV) sterilization or high-temperature sterilization. However, high-temperature sterilization requires high-power heaters, consuming a large amount of electricity to heat the liquid to the set temperature, such as 90°C or higher. This increases energy consumption, and for tableware made of materials such as plastic and rubber, high temperatures may cause the release of harmful substances or material deformation, compromising their safety and lifespan. While UV sterilization consumes less energy and does not damage materials such as plastic and rubber, it requires the installation of an additional UV module inside the dishwasher, which undoubtedly increases the cost.

[0003] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0004] To address at least one problem in the prior art, namely, how to reduce energy consumption and cost during the sterilization process of dishwashers while ensuring the safety and lifespan of tableware, this application provides a control method for a dishwasher. The dishwasher includes an inner tub and a liquid storage tank, which are connected via an air inlet. A switch assembly is provided at the air inlet. The control method includes:

[0005] After the dishwasher completes the washing mode, it obtains the current temperature of the liquid in the storage tank and the current air pressure in the inner tank.

[0006] Based on the current temperature and the current air pressure, determine whether the dishwasher meets the preset sterilization and disinfection conditions;

[0007] Based on the judgment result, the dishwasher is selectively controlled to perform sterilization and disinfection mode;

[0008] The preset sterilization mode conditions include the following two conditions:

[0009] The current temperature is greater than or equal to the preset temperature, and the preset temperature is within the temperature range of 60-70℃.

[0010] The current air pressure is greater than or equal to the preset air pressure.

[0011] In the preferred embodiment of the above control method, the step of "selectively controlling the dishwasher to perform sterilization and disinfection mode based on the judgment result" further includes:

[0012] When the current temperature is greater than or equal to the preset temperature and the current air pressure is greater than or equal to the preset air pressure, the dishwasher is controlled to execute the sterilization and disinfection mode.

[0013] In the preferred embodiment of the above control method, after the step of "controlling the dishwasher to execute the sterilization and disinfection mode", the method further includes:

[0014] Obtain the current running time of the sterilization and disinfection mode;

[0015] Based on the preset temperature, the preset running time of the sterilization and disinfection mode is determined;

[0016] Compare the current running time with the preset running time;

[0017] When the current running time is greater than or equal to the preset running time, the dishwasher is controlled to stop the sterilization and disinfection mode.

[0018] In the preferred embodiment of the above control method, the preset running time is negatively correlated with the preset temperature.

[0019] In a preferred embodiment of the above control method, after the step of "controlling the dishwasher to stop the sterilization and disinfection mode", the method further includes:

[0020] Control the dishwasher to execute the drying mode.

[0021] In the preferred embodiment of the above control method, after the step of "controlling the dishwasher to perform the drying mode", the method further includes:

[0022] After the dishwasher completes the drying mode, the drying and storage time of the tableware inside the dishwasher is obtained.

[0023] Compare the drying and storage time with the first preset time;

[0024] When the drying and storage time is greater than or equal to the first preset time, the current temperature and current air pressure are obtained so that the sterilization and disinfection mode can be executed again when the dishwasher meets the preset sterilization and disinfection conditions.

[0025] In the preferred embodiment of the above control method, after the step of "controlling the dishwasher to perform the drying mode", the method further includes:

[0026] After the dishwasher completes the drying mode, the total storage time of the tableware inside the dishwasher is obtained.

[0027] Compare the total storage time with the second preset time;

[0028] When the total storage time is greater than or equal to the second preset time, the dishwasher is controlled to stop working.

[0029] In a preferred embodiment of the above control method, the method further includes, before, after, or simultaneously with the step of "controlling the dishwasher to stop working":

[0030] Control the dishwasher door to open.

[0031] In a preferred embodiment of the above control method, the method further includes the following step before the step of "controlling the dishwasher to execute the drying mode":

[0032] Control the drainage component on the inner liner to perform the drainage operation.

[0033] In the preferred embodiment of the above control method, after the step of "obtaining the current temperature of the liquid in the storage tank", the method further includes:

[0034] Based on the current temperature and the preset temperature, determine the operating power of the heating component in the storage tank;

[0035] The heating component is controlled to operate at the specified operating power.

[0036] Those skilled in the art will understand that the dishwasher control method of this application, by using a current temperature greater than or equal to a preset temperature (within the range of 60-70℃) and a current air pressure greater than or equal to a preset air pressure as conditions for triggering the sterilization and disinfection mode, can not only effectively improve the sterilization and disinfection effect of tableware, but also ensure that the safety and service life of tableware made of materials such as plastic and rubber are not affected by high-temperature sterilization and disinfection. Furthermore, this solution uses low-temperature steam technology for sterilization and disinfection of tableware, which significantly reduces energy consumption compared to traditional high-temperature sterilization and disinfection methods, and eliminates the need for an additional ultraviolet module compared to ultraviolet sterilization and disinfection methods, thereby reducing costs.

[0037] Furthermore, based on the long negative correlation between preset running time and preset temperature, determining the preset running time of the sterilization mode according to the preset temperature can improve the sterilization and disinfection effect of tableware.

[0038] Furthermore, after controlling the dishwasher to stop executing the sterilization and disinfection mode, controlling the dishwasher to execute the drying mode can keep the tableware clean and avoid secondary contamination and bacterial growth.

[0039] Furthermore, after completing the drying cycle, the dishwasher regularly sterilizes and disinfects the tableware stored inside, ensuring the cleanliness of the tableware.

[0040] Furthermore, by controlling the drain assembly on the inner drum to perform a draining operation before controlling the dishwasher to execute the drying mode, not only can the drying effect on the dishes be improved, but energy consumption can also be reduced.

[0041] Furthermore, based on the current temperature and the preset temperature, the operating power of the heating element is determined and adjusted accordingly. This ensures that the steam temperature meets the preset sterilization and disinfection conditions, avoiding the impact of excessively low steam temperature on the sterilization and disinfection effect of tableware, as well as the problems of excessively high steam temperature leading to high energy consumption and affecting the safety and service life of tableware made of plastic, rubber, and other materials. Attached Figure Description

[0042] The preferred embodiments of the present invention are described below with reference to the accompanying drawings, in which:

[0043] Figure 1 This is a flowchart of the dishwasher control method of this application;

[0044] Figure 2 This is a logic diagram of one possible implementation of the dishwasher control method of this application. Detailed Implementation

[0045] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0046] First, combine Figure 1 The control method of the dishwasher of this application is described.

[0047] like Figure 1 As shown, to address the issue of reducing energy consumption and cost during the sterilization process of a dishwasher while ensuring the safety and lifespan of tableware, this application discloses a dishwasher comprising an inner tub and a liquid reservoir. The liquid reservoir and the inner tub are connected via an air inlet, which is equipped with a switch assembly. The inner tub is used to hold tableware, and the liquid reservoir generates steam, which enters the inner tub through the air inlet to sterilize the tableware. Based on the above configuration, the control method of this application's dishwasher includes:

[0048] S101. After the dishwasher completes the washing cycle, it acquires the current temperature of the liquid in the reservoir and the current air pressure in the inner tub. For example, a temperature sensor can be installed in the reservoir to detect the current temperature of the liquid. Alternatively, a pressure sensor can be installed in the inner tub to detect the current air pressure.

[0049] S102. Based on the current temperature and current air pressure, determine whether the dishwasher meets the preset sterilization and disinfection conditions. For example, the preset sterilization and disinfection conditions include a preset temperature and a preset air pressure. After obtaining the current temperature and current air pressure, by comparing the current temperature with the preset temperature and the current air pressure with the preset air pressure, it can be determined whether the dishwasher meets the preset sterilization and disinfection conditions.

[0050] S103. Based on the judgment result, selectively control the dishwasher to execute the sterilization and disinfection mode. For example, after determining that the dishwasher meets the preset sterilization and disinfection conditions, the dishwasher can be controlled to execute the sterilization and disinfection mode to sterilize and disinfect the tableware inside the dishwasher.

[0051] The preset sterilization mode conditions include the following two conditions:

[0052] 1) The current temperature is greater than or equal to the preset temperature, which is within the range of 60-70℃. During sterilization, a steam temperature within the range of 60-70℃ can reduce the problem of high energy consumption caused by high-temperature sterilization.

[0053] 2) The current air pressure is greater than or equal to the preset air pressure. Specifically, the current air pressure inside the liner must be greater than or equal to the preset air pressure to improve the effectiveness of low-temperature steam sterilization.

[0054] When the current temperature and air pressure meet the above conditions, the dishwasher will execute the sterilization mode. This not only reduces energy consumption and costs during the sterilization process but also prevents high-temperature sterilization from affecting the safety and lifespan of tableware made of plastic, rubber, and other materials. The liquid used can be water.

[0055] This application uses a current temperature greater than or equal to a preset temperature (within the range of 60-70℃) and a current air pressure greater than or equal to a preset air pressure as conditions to trigger the sterilization and disinfection mode. This not only effectively improves the sterilization and disinfection effect of tableware but also ensures that the safety and lifespan of tableware made of materials such as plastic and rubber are not affected by high-temperature sterilization and disinfection. Furthermore, this solution uses low-temperature steam technology for tableware sterilization and disinfection, which significantly reduces energy consumption compared to traditional high-temperature sterilization and disinfection methods. Compared to ultraviolet sterilization and disinfection methods, it eliminates the need for an additional ultraviolet module, thus reducing costs.

[0056] The preferred embodiments of the dishwasher control method of this application are described below.

[0057] In one embodiment, the step of "obtaining the current temperature of the liquid in the storage tank and the current air pressure in the inner liner" is followed by:

[0058] Control the drainage components on the inner liner to perform the drainage operation.

[0059] It should be noted that the inner drum is equipped with a drainage component to drain the waste liquid and residue generated during the washing process, ensuring the cleanliness of the dishes and the inside of the dishwasher. This application does not limit the number of drainage operations; one, two, or more drainage operations can be performed. A single drainage operation can be of a fixed duration, while two or more drainage operations can maintain a consistent duration for each operation and set a time interval between adjacent drainage operations. This drainage operation is a conventional method in the art and will not be described in detail here.

[0060] Furthermore, this application does not limit the drainage component, which can be a drainage port provided on the inner liner, wherein the drainage port is equipped with a valve body for controlling the opening or closing of the drainage port, thereby realizing the drainage operation and stopping the drainage operation.

[0061] In one embodiment, the step of "controlling the drainage assembly on the inner liner to perform a drainage operation" further includes:

[0062] Control the injection assembly to inject liquid into the storage tank;

[0063] Obtain the liquid level height;

[0064] Compare the liquid level height with the preset liquid level height;

[0065] When the liquid level is greater than or equal to the preset liquid level, the liquid injection component is controlled to stop the liquid injection operation.

[0066] It should be noted that this application does not limit the liquid injection component, which can be a liquid injection port set on the inner liner, the liquid injection port is connected to the liquid source, and the liquid injection port is equipped with a valve body to control the opening or closing of the liquid injection port, thereby realizing the liquid injection operation and stopping the liquid injection operation.

[0067] It should also be noted that a liquid level sensor is installed in the storage tank to obtain the liquid level height.

[0068] For example, let's assume a preset liquid level height H0 of 6cm. The liquid level height is obtained and compared to the preset height H0. When H ≥ 6cm, it indicates that the liquid level in the storage tank has reached the required level, therefore the injection component is controlled to stop injection.

[0069] Furthermore, the steps before, after, or simultaneously with the "controlling the injection assembly to stop the injection operation" include:

[0070] Control the heating components in the liquid storage tank to perform heating operations.

[0071] The liquid storage tank is equipped with a heating element to heat the liquid and generate steam for sterilizing and disinfecting the tableware. Furthermore, the heating element is a common type of heater in this field, and therefore will not be described in detail here.

[0072] In one implementation, the step of "selectively controlling the dishwasher to execute the sterilization and disinfection mode based on the judgment result" further includes:

[0073] When the current temperature reaches the preset temperature and the current air pressure reaches the preset air pressure, the dishwasher will be controlled to execute the sterilization and disinfection mode.

[0074] For example, let's define a preset temperature T0 of 60°C and a preset pressure P0 of 4MPa. After obtaining the current temperature T and current pressure P, compare the current temperature T with the preset temperature T0, and the current pressure P with the preset pressure P0. When T ≥ 60°C and P ≥ 4MPa, control the dishwasher to execute the sterilization and disinfection mode.

[0075] In one embodiment, the step of "controlling the dishwasher to perform sterilization mode" further includes:

[0076] Get the current running time of the sterilization and disinfection mode;

[0077] Based on the preset temperature, determine the preset running time of the sterilization and disinfection mode;

[0078] Compare the current running time with the preset running time;

[0079] When the current running time is greater than or equal to the preset running time, the dishwasher will stop the sterilization and disinfection mode.

[0080] It should be noted that since the dishwasher in this application sterilizes and disinfects tableware under a steam temperature of 60-70℃, the sterilization and disinfection mode must run for a preset time in order to achieve a good sterilization and disinfection effect.

[0081] For example, let's assume a preset temperature T0 of 60℃ and a preset running time t0 of 30 minutes. After the dishwasher starts the sterilization mode, the current running time t of the sterilization mode is obtained. The preset running time t0 of the sterilization mode is determined based on the dishwasher's preset temperature to ensure the sterilization effect on the tableware. The current running time t1 is compared with the preset running time t0. When t1 ≥ 30 minutes, the dishwasher stops the sterilization mode. When t1 < 30 minutes, the dishwasher continues to perform the sterilization mode on the tableware at 60℃.

[0082] Furthermore, the preset running time is negatively correlated with the preset temperature.

[0083] It should be noted that the preset running time is negatively correlated with the preset temperature; that is, the higher the preset temperature, the shorter the preset running time, and vice versa. For example, when the preset temperature T0 is 60℃, the preset running time t0 is 30 minutes. When the preset temperature T0 is 70℃, the preset running time t0 is 25 minutes.

[0084] In one implementation, the step of "controlling the dishwasher to stop the sterilization mode" further includes:

[0085] Control the dishwasher to execute the drying mode.

[0086] It should be noted that, to avoid secondary contamination and bacterial growth of the tableware, and to ensure its cleanliness, the dishwasher will execute a drying mode after stopping the sterilization and disinfection mode to dry the tableware. This drying mode is a common method in the field and is not limited here. For example, it could be a door-open drying mode, utilizing the temperature difference between the inside and outside of the dishwasher to dry the tableware.

[0087] Furthermore, the step of "controlling the dishwasher to perform the drying mode" includes the following:

[0088] Control the drainage components on the inner liner to perform the drainage operation.

[0089] It should be noted that, in order to improve the drying effect of the dishwasher on the dishes and reduce energy consumption, the draining operation on the inner drum should be performed before the dishwasher starts the drying mode.

[0090] In one implementation, the step of "controlling the dishwasher to perform a drying mode" is followed by:

[0091] After the dishwasher finishes the drying mode, obtain the drying and storage time of the dishes inside the dishwasher.

[0092] Compare the drying and storage time with the first preset time;

[0093] When the drying and storage time is greater than or equal to the first preset time, the current temperature and current air pressure are obtained so that the sterilization and disinfection mode can be executed again when the dishwasher meets the preset sterilization and disinfection conditions.

[0094] It should be noted that prolonged storage of tableware in the dishwasher's inner drum may lead to bacterial growth, affecting the cleanliness of the tableware. Therefore, after the dishwasher completes its drying cycle, it is necessary to periodically run a sterilization cycle on the tableware. The drying and storage time refers to the time the tableware remains in the dishwasher after the drying cycle has finished.

[0095] For example, let's define the first preset time t`0 as 12 hours. After the dishwasher completes the drying mode, the drying and storage time of the tableware is obtained. The drying and storage time t2 is compared with the first preset time t`0. When t2 ≥ 12 hours, it indicates that the tableware has been stored in the dishwasher for a relatively long time. During this period, bacteria may grow on the tableware, affecting its cleanliness. Therefore, when t2 ≥ 12 hours, the current temperature T and current air pressure P are obtained again. If the current temperature T and current air pressure P meet the preset sterilization and disinfection conditions, the sterilization and disinfection mode is executed again to sterilize and disinfect the tableware, ensuring its cleanliness.

[0096] In one implementation, the step of "controlling the dishwasher to perform a drying mode" is followed by:

[0097] After the dishwasher completes the drying mode, obtain the total storage time of the dishes inside the dishwasher;

[0098] Compare the total storage time with the second preset time;

[0099] When the total storage time is greater than or equal to the second preset time, the dishwasher will stop working.

[0100] It should be noted that prolonged operation of the dishwasher may accelerate wear and tear and aging of the equipment. Therefore, the dishwasher will stop operating when the total storage time of the dishes is greater than or equal to the second preset time. The total storage time refers to the time the dishes have been stored in the dishwasher after the first drying cycle has finished.

[0101] For example, let's consider a second preset time t``0 of 48 hours. After the dishwasher completes the drying mode, the total storage time t3 of the dishes inside the dishwasher is obtained. The total storage time t3 is compared with the second preset time t``0. If t3 ≥ 48 hours, it indicates that the dishes have been stored for too long. Specifically, if the total storage time t3 is less than 48 hours, the dishwasher remains in standby mode while the dishes are stored, and it periodically performs sterilization and disinfection, resulting in a longer operating time. To avoid potential wear and accelerated aging of the dishwasher due to prolonged operation, the dishwasher is stopped when t3 ≥ 48 hours.

[0102] Furthermore, the steps before, after, or simultaneously with "controlling the dishwasher to stop working" may include:

[0103] Control the dishwasher door to open.

[0104] It should be noted that, to prevent bacteria from growing on the dishes inside the dishwasher in a closed environment after it stops running, the dishwasher door is kept closed.

[0105] In one embodiment, the step of "obtaining the current temperature of the liquid in the storage tank" is followed by:

[0106] Based on the current temperature and the preset temperature, determine the operating power of the heating components in the storage tank;

[0107] Control the heating components to operate according to the operating power.

[0108] It should be noted that, to avoid the dishwasher's sterilization process where excessively high temperatures could affect the safety and lifespan of plastic and rubber tableware, or excessively low temperatures could affect the sterilization effect, the dishwasher determines the operating power of the heating element in the liquid reservoir after the wash cycle is complete, based on the current and preset temperatures of the liquid. The heating element is then controlled to operate at this power to ensure the steam temperature meets the preset sterilization conditions.
