Description

Technical Field

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

[0002] After the existing dishwasher finishes washing the tableware, the tableware will generally be placed in the inner tank of the dishwasher for a period of time before being taken out for use. Since the inner tank of the dishwasher is a relatively humid closed environment, the tableware stored in the inner tank for a long time will cause odors to be generated, and it is also easy to breed bacteria, which is not good for the health of consumers. For example, users do not often go into the kitchen to cook due to business trips or other factors, resulting in low frequency of use of the dishwasher, resulting in the tableware being placed in the inner tank for a period of time before being taken out. Therefore, there is a great demand for storage treatment of the washed tableware. The storage treatment is generally achieved by turning on the heating tube, fan, and UV lamp to dry and disinfect the tableware in the inner tank;

[0003] Dishwashers on the market use an intermittent manner to store and process the tableware in the inner tank, that is, the dishwasher stores and processes the tableware once at a preset interval. The preset time of the interval is set by the user and remains unchanged, so that the time when the dishwasher starts the storage process each time remains unchanged. Since the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank may change after each storage process, if the next storage process is still performed according to the preset time of the interval, the start time of the next storage process will be delayed due to the increase in the number of tableware in the inner tank and the increase in the humidity of the environment inside and outside the inner tank, resulting in odor and bacteria breeding in the inner tank, contaminating the tableware; or the start time of the next storage process will be advanced due to the decrease in the number of tableware in the inner tank and the decrease in the temperature and humidity of the environment inside and outside the inner tank, resulting in energy waste.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a control method for a dishwasher and a dishwasher. By detecting the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank, the interval time of the dishwasher's storage treatment is obtained, so that the interval time of the dishwasher's storage treatment changes with the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank, so that the start time of each storage treatment of the dishwasher becomes reasonable, so as to avoid contamination of the tableware in the inner tank and reduce energy waste.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] The present invention provides a control method for a dishwasher, wherein the dishwasher has an inner tank for containing tableware, and the dishwasher performs intermittent storage processing on the tableware in the inner tank;

[0008] Determine the interval time T for dishwasher storage and treatment based on the number of dishes in the inner tank and the temperature and humidity of the environment inside and outside the inner tank.

[0009] Furthermore, the dishwasher performs N storage treatments on the tableware in the inner tank, and the interval time is the difference between the end time of the N-1th storage treatment of the dishwasher and the start time of the Nth storage treatment of the dishwasher;

[0010] By obtaining the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank at the end of the N-1th storage process of the dishwasher, the interval time T is determined. The interval time T is negatively correlated with the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank.

[0011] Furthermore, when the interval time T is reached, if it is detected that the actual opening times of the dishwasher door body is greater than or equal to the set opening times, the dishwasher cancels the Nth storage process;

[0012] If it is detected that the actual opening times of the dishwasher door are less than the set opening times, the dishwasher starts the Nth storage process.

[0013] Furthermore, the dishwasher is connected to the cooking device through the communication module, and the actual opening times of the dishwasher door are obtained according to the number of times the cooking device is opened when the interval time T is reached.

[0014] Furthermore, after detecting that the actual number of times the dishwasher door is opened is less than the set number of times, if it is detected that the dishwasher is executing a washing program, a rinsing program and / or a drying program, the dishwasher will start the Nth storage process after waiting for the washing program, the rinsing program and / or the drying program to be completed.

[0015] Furthermore, the dishwasher's storage treatment for the tableware in the inner tank includes the dishwasher drying and / or disinfecting the tableware in the inner tank; detecting the temperature and humidity of the environment inside and outside the inner tank when the dishwasher starts the storage treatment, and determining the parameters for the dishwasher's drying treatment or disinfection treatment of the tableware.

[0016] Furthermore, a drying module is provided in the inner tank, and the drying module includes a fan and a heating module, and the parameters of the tableware drying process include the rotation speed of the fan and the heating temperature of the heating module;

[0017] If the internal temperature of the inner tank is not greater than the external temperature, and the internal humidity of the inner tank is not greater than the external humidity, the speed of the fan is the first speed, and the heating temperature of the heating module is the first temperature;

[0018] If the internal ambient temperature of the liner is not greater than the external ambient temperature, and the internal ambient humidity of the liner is greater than the external ambient humidity, the rotation speed of the fan is a second rotation speed greater than the first rotation speed, and the heating temperature of the heating module is the first temperature;

[0019] If the internal ambient temperature of the liner is greater than the external ambient temperature and the internal ambient humidity of the liner is greater than the external ambient humidity, the fan speed is the second speed and the heating temperature of the heating module is the second temperature greater than the first temperature.

[0020] Furthermore, the dishwasher is equipped with a battery for powering the drying module. After detecting that the dishwasher is powered off, the battery starts working, and the battery powers the chip inside the drying module, turning on the fan to intermittently dry the tableware in the inner tank.

[0021] Furthermore, the fan start time can be set in advance by the user, or the fan is connected to the household appliance through a communication module. The fan start time can be determined according to the usage of the household appliance. If the number of times the household appliance is used is less than the set number of times when the set time is reached, the fan is turned on.

[0022] The present invention also provides a dishwasher, and adopts the control method of the dishwasher provided by the above technical solution.

[0023] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0024] By detecting the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank, the interval time of the dishwasher's storage and processing is obtained, so that the interval time of the dishwasher's storage and processing changes with the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank, thereby making the start time of each storage and processing of the dishwasher reasonable, avoiding contamination of the tableware in the inner tank and reducing energy waste.

[0025] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0030] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1 As shown, the present invention provides a control method for a dishwasher, wherein the dishwasher has an inner tank for holding tableware, and the dishwasher performs intermittent storage processing on the tableware in the inner tank;

[0033] Determine the interval time T for dishwasher storage and treatment based on the number of dishes in the inner tank and the temperature and humidity of the environment inside and outside the inner tank.

[0034] In an embodiment of the present invention, the interval time of the dishwasher's storage treatment is obtained by detecting the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank, so that the interval time of the dishwasher's storage treatment changes with the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank, thereby making the start time of each storage treatment of the dishwasher reasonable, avoiding contamination of the tableware in the inner tank and reducing energy waste.

[0035] The dishwasher includes a door body provided with an access opening for taking tableware out of or placing tableware in the inner tank and an opening and closing access opening; when the door body opens the access opening, tableware can be placed in or taken out of the inner tank, and when the door body closes the access opening, the inner tank is in a closed environment.

[0036] Specifically, the front side of the inner container is provided with a front access opening for taking out or placing tableware from the inner container and a front door for opening and closing the front access opening, or the top side of the inner container is provided with a top access opening for taking out or placing tableware from the inner container and a top door for opening and closing the top access opening;

[0037] The dishwasher's storage process for tableware includes drying and disinfecting the tableware in the inner tank, and the dishwasher's cleaning process for tableware includes washing, rinsing and drying the tableware. Under normal circumstances, after the dishwasher dries the tableware, if the tableware is not taken out of the inner tank for a long time, the tableware is stored intermittently to reduce energy waste. For example, after the dishwasher completes the first storage process for the tableware, the tableware continues to be stored in the inner tank of the dishwasher. When the storage time reaches the interval time T, the dishwasher starts the second storage process for the tableware. It should be noted that under normal circumstances, the dishwasher door is in a closed state during the storage and storage of the tableware. Of course, there are situations where the dishwasher door is opened and the tableware is taken out.

[0038] Specifically, the dishwasher performs N storage treatments on the tableware in the inner tank, and the interval time is the difference between the end time of the N-1th storage treatment of the dishwasher and the start time of the Nth storage treatment of the dishwasher;

[0039] By obtaining the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank at the end of the N-1th storage process of the dishwasher, the interval time T is determined. The interval time T is negatively correlated with the number of tableware in the inner tank and the temperature and humidity of the environment inside and outside the inner tank.

[0040] By determining the interval time T, the start time of the Nth storage process of the dishwasher can be determined; for example, the dishwasher performs three storage processes on the tableware. After the first storage process of the dishwasher is completed, the number of tableware in the inner tank is obtained as N1, the humidity of the environment in the inner tank is the first humidity, the temperature is the first temperature, the humidity of the environment outside the inner tank is the second humidity, and the temperature is the second temperature. The interval time between the end of the first storage process of the dishwasher and the start of the second storage process of the dishwasher is determined to be T1. After the interval time T1 is reached, the dishwasher starts the second storage process;

[0041] After the second storage process of the dishwasher is completed, the number of dishes in the inner tank is obtained to be N2 which is greater than N1, the humidity of the environment outside the inner tank is a third humidity which is greater than the first humidity, the temperature is a third temperature which is greater than the first temperature, the humidity of the environment outside the inner tank is the second humidity, the temperature is the second temperature, and the interval time between the end of the second storage process of the dishwasher and the start of the third storage process of the dishwasher is determined to be T2 which is less than T1, and after the interval time T2 is reached, the dishwasher starts the third storage process;

[0042] The more tableware there is, the higher the humidity and temperature are. The more tableware is in a high temperature and high humidity environment, the easier it is to mold and produce bacteria, and the more necessary it is to store and process the tableware as soon as possible. The high temperature and high humidity environment here can be the internal environment of the inner tank or the external environment of the inner tank.

[0043] The change in the number of tableware may be due to the user taking out the tableware from the inner tank, resulting in a decrease in the number of tableware. The change in external temperature and humidity may be due to weather changes, for example, a sunny day becomes cloudy. The change in internal temperature and humidity may be due to changes in heating temperature and fan speed during this storage process, combined with changes in external temperature and humidity, which lead to changes in internal temperature and humidity after this storage process.

[0044] like Figure 1 As shown, in the embodiment of the present invention, when the interval time T is reached, if it is detected that the actual opening times of the dishwasher door body are greater than or equal to the set opening times, the dishwasher cancels the Nth storage process;

[0045] If it is detected that the actual opening times of the dishwasher door are less than the set opening times, the dishwasher starts the Nth storage process.

[0046] In the embodiment of the present invention, during the interval time T, if the actual number of times the door is opened is greater than or equal to the set number of times the door is opened, it means that the number of times the door is opened is relatively large. Multiple openings of the door can ventilate the inner tank, dry the tableware, and prevent the tableware in the inner tank from getting moldy and producing odor. Therefore, the dishwasher may not perform the next storage process, reducing energy waste. During the interval time T, there is a possibility that the user opens the door multiple times to take the tableware out of the inner tank.

[0047] If the actual number of times the door is opened is less than the set number of times, it means that the door is opened less frequently or even not once, and the inner tank cannot be effectively ventilated. Therefore, the dishwasher needs to be stored for the next time.

[0048] Furthermore, the dishwasher is connected to the cooking device through the communication module, and the actual opening times of the dishwasher door are obtained according to the number of times the cooking device is opened when the interval time T is reached.

[0049] The cooking device is a gas stove, and the dishwasher is provided with a controller. The interior of the dishwasher door is hollow to form a accommodating cavity, and the controller is arranged in the accommodating cavity. The cooking device and the controller are wirelessly or wiredly connected. The cooking device transmits the number of opening times to the controller. The controller obtains the number of opening times of the dishwasher door according to the number of opening times of the cooking device, and compares the obtained number of opening times of the dishwasher door with the set number of opening times.

[0050] Furthermore, after detecting that the actual number of times the dishwasher door is opened is less than the set number of times, if it is detected that the dishwasher is executing a washing program, a rinsing program and / or a drying program, the dishwasher will start the Nth storage process after waiting for the washing program, the rinsing program and / or the drying program to be completed.

[0051] During the interval time T, the door is open and the tableware is taken out of the inner tank. It is also possible that tableware with a certain degree of dirt is put into the dishwasher. In order to prevent contamination of the tableware already in the inner tank, there is a possibility that all the tableware in the inner tank will be rewashed. Therefore, before the Nth storage process begins, it is necessary to detect whether the dishwasher is executing a program. Only after the program executed by the dishwasher is completed can the dishwasher enter the Nth storage process.

[0052] In an embodiment of the present invention, the way in which the dishwasher performs storage processing on the tableware in the inner tank includes the dishwasher performing drying processing and / or disinfecting processing on the tableware in the inner tank; detecting the temperature and humidity of the environment inside and outside the inner tank when the dishwasher starts the storage processing, and determining the parameters for the dishwasher to dry the tableware or the parameters for the disinfection processing of the tableware.

[0053] In the embodiment of the present invention, a temperature sensor for detecting the temperature of the environment inside the inner tank and a humidity sensor for detecting the humidity are provided inside the inner tank of the dishwasher, and a temperature sensor for detecting the temperature of the environment outside the inner tank and a humidity sensor are provided outside the dishwasher;

[0054] Taking the detection of the temperature and humidity of the internal environment of the inner tank as an example, the dishwasher includes a drying module for drying the tableware and a disinfection module for disinfecting the tableware. The drying module includes a fan and a heating module; the time required for the dishwasher to store and process the tableware is the preset storage time. Each time the dishwasher performs a storage process, the fan is first controlled to work, and the temperature and humidity in the inner tank are detected by a humidity sensor and a temperature sensor. Then, according to the temperature and humidity in the inner tank, it is judged whether the dishwasher has completed the drying process. If the drying process is completed, the disinfection module is controlled to work, and the fan is controlled to stop working. After the disinfection module works for the first preset time, it is judged whether the storage time of the dishwasher reaches the preset storage time. If not, it returns to continue to control the fan to work to prevent moisture. If so, the dishwasher ends this storage process. The preset storage time can be calibrated according to actual conditions.

[0055] The disinfection module is arranged in an inner tank and works by ultraviolet disinfection, high temperature disinfection, electrolytic disinfection or dry disinfection.

[0056] Whether the humidity sensor fails is detected according to the humidity in the inner tank, wherein if the humidity sensor fails, the fan is controlled to work continuously for a second preset time, and then it is determined that the dishwasher has completed the drying process.

[0057] An air inlet is arranged on the inner tank, a fan is arranged at the air inlet, and a heating module is arranged in the inner tank. During the drying process, the fan and the heating module are turned on simultaneously or at different times. The fan is used to supply air into the inner tank, and the air is heated by the heating module to dry the dishes in the inner tank. A simple structure such as a heating tube can be selected. The fan is turned on to accelerate the circulation of ambient air inside and outside the dishwasher to reduce the humidity of the internal environment of the dishwasher, and the heating module arranged in the dishwasher is turned on to heat and evaporate the air with high humidity inside the dishwasher, thereby further increasing the humidity reduction rate and achieving a good dehumidification effect.

[0058] An air outlet is formed on the door body, and an air outlet device is provided at the air outlet. The air outlet device may be an air outlet fan, and the air outlet device is used to extract the gas in the inner tank. Therefore, the air outlet is arranged higher than the air inlet, so that the airflow sent into the inner tank through the air inlet needs to rise and flow a certain distance in the inner tank before it can be blown out from the air outlet. This can effectively increase the flow area and flow sufficiency of the airflow in the inner tank, greatly improve the drying effect and drying efficiency, thereby shortening the drying time and improving the user experience. The controller arranged in the door body is connected to the fan, heating module, disinfection module, temperature sensor and humidity sensor.

[0059] Since the inner tank is in a relatively closed state, part of the outside air that enters the inner tank remains in the inner tank, making the pressure inside the inner tank relatively high compared to the outside air. At this time, after the fan is turned on for the first time, the controller controls the air outlet fan to turn on. Since the air pressure inside the inner tank is relatively high, this is conducive to the outflow of air and liquid inside the inner tank. After the fan and the air outlet fan are turned on for the first time at the same time for the second time, the controller controls the fan and the air outlet fan to be turned off at the same time for the first time. In this way, the purpose of gradually updating the air in the inner tank in different time periods is achieved. The setting of the second time period can also ensure the effect of air renewal in the inner tank, and avoid the fan and the air outlet fan from running too long and affecting their service life. The controller stores the preset number of times the fan and the air outlet fan are turned on at the same time. After the number of simultaneous openings is greater than the preset number, the controller fan and the air outlet fan are turned off.

[0060] When the storage starts, the drying module is controlled to start working until the humidity value in the inner tank is less than or equal to the first humidity threshold; after the drying module stops working, it is detected whether the humidity value in the inner tank is greater than the second humidity threshold, and the second humidity threshold is greater than the first humidity threshold; after detecting that the humidity value in the inner tank is greater than the second humidity threshold, the disinfection module is controlled to start working. That is, when the dishwasher starts to execute the storage program, the drying module is controlled to start working until the humidity value in the inner tank is less than or equal to the first humidity threshold. In this way, the air humidity value in the inner tank is reduced, thereby avoiding high air humidity in the inner tank, which leads to a large number of bacteria.

[0061] It is understandable that after the drying module stops working, the water droplets remaining in the inner tank will evaporate into the air in the inner tank, thereby increasing the humidity in the inner tank and causing bacteria to grow in large numbers. Therefore, after the drying module stops working, if the humidity value in the inner tank is detected to be greater than the second humidity threshold, the disinfection module is controlled to start working. Since the disinfection module will only be triggered to start under certain conditions, the energy consumption of the dishwasher can be reduced while ensuring the disinfection rate of the dishwasher, thereby improving the user experience.

[0062] Furthermore, the parameters of the tableware drying process include the speed of the fan and the heating temperature of the heating module;

[0063] If the internal ambient temperature of the liner is not greater than the external ambient temperature, and the internal ambient humidity of the liner is not greater than the external ambient humidity, the speed of the fan is the first speed, and the heating temperature of the heating module is the first temperature; in this environment, the speed of the fan is the first speed, and the first speed is 0, so that the gas in the liner is kept from circulating, and the air with high external humidity is prevented from entering the liner, and the heating temperature of the heating module is the first temperature, and the first temperature is 0;

[0064] If the internal ambient temperature of the liner is not greater than the external ambient temperature, and the internal ambient humidity of the liner is greater than the external ambient humidity, the speed of the fan is a second speed greater than the first speed, and the heating temperature of the heating module is the first temperature; in this environment, if the heating module is turned on, the gas entering the liner from the outside will condense on the side wall of the liner, thereby returning to moisture. Therefore, blowing cold air at this time can reduce the humidity, so that the speed of the fan is the second speed of the first speed, the heating temperature of the heating module is the first temperature, and the first temperature is 0;

[0065] If the temperature inside the liner is higher than the temperature outside the liner, and the humidity inside the liner is higher than the humidity outside the liner, the speed of the fan is the second speed, and the heating temperature of the heating module is the second temperature higher than the first temperature. In this environment, the inside of the liner is a high temperature and high humidity environment, and condensation is easy to form inside the liner, so hot air is continuously blown, the speed of the fan is the second speed, and the heating temperature of the heating module is the second temperature higher than the first temperature.

[0066] In addition, if the internal ambient temperature of the inner tank is greater than the external ambient temperature, and the internal ambient humidity of the inner tank is not greater than the external ambient humidity, then it is further determined whether the external ambient temperature is high or low. If it is high, it is a high temperature and high humidity environment, and both the fan and the heating module are working. If it is low temperature, it is a low temperature and high humidity environment, the fan is working and the heating mode is not working, or both the fan and the heating module are not working.

[0067] like Figure 1As shown, in an embodiment of the present invention, the dishwasher is loaded with a battery for powering the drying module. After detecting that the dishwasher is powered off, the battery starts to work, and the battery powers the chip inside the drying module, turning on the fan to intermittently dry the tableware in the inner tank.

[0068] In an embodiment of the present invention, the battery is a storage battery. If the user is away from home for a long time and there is a power outage, the storage battery will start working and only supply power to the chip inside the drying module. The low-power fan will be turned on regularly to ventilate the inside of the dishwasher, keep the dishes dry for a long time, and realize the storage and processing of tableware.

[0069] The fan start time can be set in advance by the user, or the fan is connected to the household appliance through a communication module. The fan start time can be determined according to the usage of the household appliance. If the number of times the household appliance is used is less than the set number of times when the set time is reached, the fan is turned on.

[0070] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
