Dish-washing machine reservation method and dish-washing machine

Abstract

Before the dish-washing machine runs, the time length of the reservation process of the dish-washing machine and the temperature T outside a washing cavity of the dish-washing machine are obtained, whether the time length of the reservation process is larger than a first time value or not and whether the temperature T outside the washing cavity is larger than a first temperature value or not are judged, and if yes, the dish-washing machine is started. If the reservation time of the dish-washing machine is too long and the temperature outside the washing cavity is too high, high-temperature disinfection is conducted in the reservation process of the dish-washing machine at a preset time interval, and if the reservation time of the dish-washing machine is not too long, high-temperature disinfection is not conducted in the reservation process of the dish-washing machine. In the reservation process of the dish-washing machine, residues of a dinner plate in a washing cavity are difficult to clean, and the residues breed bacteria to generate peculiar smell; and the soaking time of the tableware is determined according to the length of the reserved time before washing, so that food residues on the tableware are softened and are convenient to wash, and the washing effect of the dish washing machine is enhanced on the premise of ensuring water conservation.

Description

Technical Field

[0001] The invention belongs to the field of dishwasher reservation, and in particular relates to a dishwasher reservation method and a dishwasher. Background Art

[0002] In modern society, with the continuous development of society and the continuous improvement of living standards, more and more people are starting to use dishwashers. Now dishwashers all support scheduled dishwashing. The dishes are placed in the dishwasher and a scheduled time is set for washing. Generally, the scheduled time is relatively long, which will cause the dish residues to become hard and difficult to clean, and the residues in hot weather will breed bacteria and produce odor. In addition, in addition to the long scheduled time causing the tableware residues to become hard and difficult to clean, and the residues in hot weather will breed bacteria and produce odor, the existing dishwasher technology also has other defects. For example, when the scheduled time is too long and the temperature outside the washing chamber is too high, the food residues on the tableware in the dishwasher may be difficult to clean, and the cleaning effect may not be thorough enough, resulting in bacteria and stains still remaining on the tableware, and the cleaning effect of the dishwasher may be greatly reduced.

[0003] The present invention is proposed in view of the above problems in order to solve these problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a dishwasher reservation method and a dishwasher. Through the invention, the washing time of the dishwasher can be reduced, the washing efficiency can be improved, the dirt and wear inside the dishwasher can be reduced, and the dishwasher can be kept in good working condition.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A method for reserving a dishwasher, before the dishwasher is operated, obtaining the duration of the reservation process of the dishwasher and the temperature T outside the washing chamber of the dishwasher,

[0007] Determine whether the duration of the reservation process exceeds the first time value, and at the same time determine whether the temperature T outside the washing chamber exceeds the first temperature value,

[0008] If so, high temperature disinfection is performed at a preset time interval during the reservation process of the dishwasher.

[0009] If not, high temperature disinfection will not be performed during the reservation process of the dishwasher.

[0010] Furthermore, the reservation method further comprises obtaining the volume of the dishes in the washing chamber of the dishwasher as a percentage of the volume of the washing chamber before the dishwasher is operated,

[0011] determining whether the volume of the dishes in the washing chamber accounts for a volume of the washing chamber that is greater than a second set value,

[0012] If so, the dishwasher soaks the dishes in the washing chamber before washing.

[0013] If not, the dishwasher sprays and wets the dishes in the washing cavity before washing.

[0014] Furthermore, before starting to wash, the dishwasher determines the time to soak the dishes according to the length of the reserved time.

[0015] Furthermore, before washing, the dishwasher obtains the volume of the dishes in the washing cavity occupied by the dishes in the washing cavity.

[0016] determining whether the volume of the dishes in the washing chamber accounts for a volume of the washing chamber that is greater than a second set value,

[0017] If yes, the dishwasher automatically starts the strong wash program.

[0018] If not, the dishwasher defaults to the standard washing mode.

[0019] Furthermore, the washing chamber is equipped with an image acquisition device.

[0020] The image of the dishes in the washing chamber is obtained by an image acquisition device and uploaded to the cloud platform.

[0021] The cloud platform calculates the volume of the washing cavity occupied by the dishes in the washing cavity according to the picture of the dishes in the washing cavity.

[0022] Furthermore, the user's indoor temperature T1 is taken in real time through other devices.

[0023] The dishwasher obtains the local weather real-time data T2 in real time.

[0024] The temperature outside the washing chamber T is calculated by weighting the user's indoor temperature T1 and T2, that is,

[0025] T=λT1+(1-λ)T2, 0<=λ<=1.

[0026] Furthermore, the dishwasher is connected to other devices for communication.

[0027] After obtaining the user's indoor temperature T1, other devices send the user's indoor temperature T1 to the dishwasher.

[0028] Furthermore, during the reservation process of the dishwasher, the dishwasher automatically adjusts the time and temperature of the reservation process according to the conditions of the dishes in the washing chamber.

[0029] Furthermore, a dishwasher is provided, wherein a temperature sensor is arranged outside the washing chamber of the dishwasher for directly measuring the indoor temperature of the user as the temperature T outside the washing chamber.

[0030] Furthermore, the washing chamber of the dishwasher is provided with a spray arm.

[0031] When it is determined that the volume of the dishes in the washing chamber accounts for a volume of the washing chamber that is less than or equal to a second set value, the spray arm is used to spray and wet the dishes in the washing chamber.

[0032] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0033] Put the dishes in the dishwasher and set a time for washing dishes. If the set time is greater than four hours, the food residue on the dishes will harden, making it difficult to clean the dishes. If the temperature outside the washing chamber is greater than 25 degrees Celsius, the food residue on the dishes will breed bacteria and produce odor. Therefore, in order to solve the above problems, the present application satisfies the requirement that when the set time and the temperature outside the washing chamber are greater than the first set value, high-temperature disinfection is performed once an hour during the reservation process, and the door is automatically opened and closed after disinfection, so as to avoid the problem that the dishes are difficult to clean, breed bacteria and produce odor due to the high temperature outside the washing chamber, thereby enhancing the user's experience. The present application determines the softening method of the food residue on the dishes before washing by the volume of the dishes in the washing chamber accounting for the volume of the washing chamber, so as to reduce the use of water and achieve the purpose of saving water resources. In addition, all the dishes in the washing chamber are covered while ensuring water conservation, ensuring that every corner of the dishes can be fully moistened, which can reduce the washing time, improve the washing efficiency, reduce the dirt and wear inside the dishwasher, and keep the machine in good working condition.

[0041] Example 1

[0042] A method for reserving a dishwasher, before the dishwasher is operated, the duration of the reservation process of the dishwasher and the temperature T outside the washing chamber of the dishwasher are obtained, the reservation process is the time from the reservation start time to the start of washing, and it is judged whether the duration of the reservation process exceeds a first time value, and at the same time, it is judged whether the temperature T outside the washing chamber exceeds a first temperature value, if the duration of the reservation process exceeds the first time value and the temperature T outside the washing chamber exceeds the first temperature value, then high-temperature disinfection is performed at a preset time interval during the reservation process of the dishwasher. The preset time interval is one hour, that is, at this time, the dishwasher performs disinfection work every hour, the first time value of the reservation process of the dishwasher is 4 hours, and the first temperature value of the temperature T outside the washing chamber of the dishwasher is 25°C, when it is judged that the dishwasher simultaneously satisfies the reservation process time greater than 4 hours and the temperature T outside the washing chamber of the dishwasher is greater than 25°C, then high-temperature disinfection is performed every hour during the reservation process of the dishwasher, and after the high-temperature disinfection, the dishwasher automatically opens the door for a period of time and then closes the door of the dishwasher. The dishwasher automatically opens the door after high-temperature disinfection and then automatically closes the door 10 minutes later; when the time for the dishwasher to meet the reservation process is greater than 4 hours, but the temperature T outside the washing chamber of the dishwasher is less than or equal to 25°C, high-temperature disinfection is not performed during the reservation process of the dishwasher; or, when the time for the dishwasher reservation process is less than or equal to 4 hours, and the temperature T outside the washing chamber of the dishwasher is less than or equal to 25°C, high-temperature disinfection is also not performed during the reservation process of the dishwasher.

[0043] In this embodiment, the temperature T outside the washing chamber can be obtained by taking the user's indoor temperature T1 in real time, and the dishwasher obtains the local weather real-time data T2 in real time. The temperature T outside the washing chamber is calculated by weighted calculation based on the user's indoor temperature T1 and T2, that is, T=λT1+(1-λ)T2, 0<=λ<=1. The value of λ varies according to the time and temperature in different regions of the country. According to the Qinling-Huaihe line, the country is divided into the north and south regions. The south of the Qinling-Huaihe line is the southern region, and the north of the Qinling-Huaihe line is the northern region. Among them, the λ value in the southern region from June to September is 0.9, and the λ value in the southern region except June to September including June and September is 0.7. The λ value in the northern region from June to September is 0.8, and the λ value in the northern region except June to September including June and September is 0.6.

[0044] In this embodiment, the temperature sensor set in the dishwasher or other equipment in the user's room obtains the user's indoor temperature T1, and the indoor temperature T1 can be displayed on the display panel of the dishwasher. The temperature sensor in the air conditioner or thermostat converts the temperature data into an electrical signal, and the temperature sensor is connected to the home network to receive and send indoor temperature data. Alternatively, a temperature sensor is set outside the washing chamber of the dishwasher to directly measure the user's indoor temperature as the temperature outside the washing chamber T, and the device and the network are connected through a gateway or router; the temperature sensor and other electrical appliances, air conditioners, humidifiers, etc. are intelligently interacted through a cloud server. When the temperature sensor detects a temperature change, it will send the data to the cloud server, and then the cloud server will pass it to the dishwasher according to the detected indoor real-time temperature. The temperature outside the washing chamber T in this application is obtained by weighting the user's indoor temperature T1 and the local weather real-time data T2, so that the obtained temperature outside the washing chamber is more accurate, the error is reduced, and the problem of the dishwasher being difficult to disinfect and clean the dishes is solved, and the user's experience is increased.

[0045] In this embodiment, the reservation method also includes installing an image acquisition device in the washing cavity. Before the dishwasher is operated, a picture of the tableware in the washing cavity is obtained through the image acquisition device and uploaded to a cloud platform. The cloud platform obtains the picture of the tableware through the image acquisition device and calculates its volume, so as to more accurately determine the volume occupied by the tableware in the washing cavity, thereby better controlling the washing process.

[0046] In this embodiment, the image acquisition device installed in the washing chamber is used to determine whether the volume of the tableware in the washing chamber accounts for more than a second set value. The second set value is set to 2 / 5 of the volume of the tableware in the washing chamber. The specific calculation method is: the cloud platform analyzes the ratio of the bottom area and height of the tableware in the washing chamber to the bottom area and height of the washing chamber according to the picture of the tableware in the washing chamber, and multiplies the ratio of the bottom area and height of the tableware in the washing chamber to the bottom area and height of the washing chamber, so as to obtain the ratio of the volume of the tableware in the washing chamber to the volume of the washing chamber. If it is determined that the volume of the tableware in the washing chamber accounts for more than 2 / 5 of the volume of the washing chamber, the dishwasher soaks the tableware in the washing chamber before washing. The dishwasher determines the soaking time of the tableware according to the length of the reservation time. If the reservation process is too long, the tableware residue may harden and become difficult to clean, so it is necessary to soak it and wet it for convenient washing.

[0047] In this embodiment, under the premise that the volume of the dishes in the washing chamber accounts for more than 2 / 5 of the volume of the washing chamber, the soaking time of the dishes is determined according to the time of the reservation process. For example: under the premise that the volume of the dishes in the washing chamber accounts for more than 2 / 5 of the volume of the washing chamber, if the reservation process time exceeds 8 hours and it is judged that the volume of the dishes in the washing chamber accounts for more than 2 / 5 of the volume of the washing chamber, the dishes need to be soaked and wetted 40 minutes before washing, if the reservation process time is greater than the first time value of 4 hours and less than 8 hours, the dishes are soaked and wetted for 30 minutes, and if the reservation process time is less than or equal to the first time value of 4 hours, the dishes are soaked and wetted for 30 minutes.

[0048] In this embodiment, the cloud platform calculates the volume of the tableware in the washing cavity based on the picture of the tableware in the washing cavity. The present application calculates and judges through the cloud platform. The cloud platform has computing functions and does not need to perform calculations locally. The advantage of cloud computing is that it can provide powerful computing power and storage space, allowing users to complete computing tasks more efficiently. Through cloud computing, users can quickly expand computing resources as needed, with high flexibility and cost-effectiveness, and can realize intelligent control of the operation of the dishwasher, improve the user experience, and reduce wear and damage to the tableware by precisely controlling the washing process, thereby extending the service life of the tableware.

[0049] In this embodiment, the dishwasher does not perform disinfection two hours before the start of washing. Not performing disinfection two hours before the start of washing can save energy consumption of the dishwasher, thereby being more energy-saving and environmentally friendly. At the same time, not performing disinfection two hours before the start of washing can reduce the impact of noise and heat generated by the dishwasher during operation on the surrounding environment. Not performing disinfection two hours before the start of washing can avoid the user being disturbed by the disinfection of the dishwasher when performing other activities, thereby improving the user's experience. Moreover, not performing disinfection two hours before the start of washing can avoid the burden on the dishwasher itself caused by long-term continuous operation, thereby extending the service life of the dishwasher.

[0050] In this embodiment, the washing chamber of the dishwasher is provided with a spray arm. When it is determined that the volume of the dishes in the washing chamber accounts for less than or equal to 2 / 5 of the volume of the washing chamber, the spray arm is used to spray and moisten the dishes in the washing chamber. In the present application, when it is determined that the volume of the dishes in the washing chamber accounts for less than or equal to 2 / 5 of the volume of the washing chamber, the volume of the dishes in the washing chamber is relatively small at this time. The spray arm is used to spray water to moisten the dishes, and the spray intensity and range can be adjusted, which can reduce the amount of water used and achieve the purpose of saving water resources; and the spray arm can cover the dishes more comprehensively to ensure that every corner can be fully washed, which can reduce the washing time and improve the washing efficiency.

[0051] In this embodiment, the washing programs of the dishwasher include but are not limited to double-sided washing and strong washing. Before washing, the dishwasher obtains the volume of the dishes in the washing cavity occupied by the washing cavity, and determines whether the volume of the dishes in the washing cavity accounts for more than 2 / 5 of the volume of the washing cavity. If so, the dishwasher automatically starts the double-sided washing or strong washing program. If not, the dishwasher defaults to the standard washing mode for washing. If the volume of the dishes is small, the dishwasher defaults to the standard washing mode for washing, which can save water resources and electricity. In addition, the automatic identification of the volume of the dishes and the selection of the appropriate washing program can greatly reduce the user's operation time and energy and improve the washing efficiency.

[0052] In this embodiment, the double-sided washing program of the dishwasher is to thoroughly clean the dishes through the upper and lower double water flow, thereby improving the washing effect, and to spray the tableware in two directions through the upper and lower double water flow, thereby achieving more thorough cleaning. This technology is different from the straight-line spray arm of the traditional dishwasher. Its advantage lies in achieving upper and lower two-way spraying, and double-sided wrapping and washing of the tableware. The double-sided washing program is achieved by utilizing the built-in spray arm and washing program control of the dishwasher. Inside the dishwasher, the spray arm is used to spray water. The component generates a strong water flow through high-speed rotation to clean the tableware. In the double-sided washing mode, the dishwasher will control the up and down movement of the spray arm during the washing process to generate upper and lower double water flow, and spray the tableware in two directions. This double-sided washing program can more thoroughly clean the front and back of the tableware, thereby improving the washing effect. In order to achieve better washing results, the dishwasher will also be equipped with corresponding washing programs; for example, the dishwasher is equipped with multiple washing programs such as strong wash, energy-saving wash, and quick wash. The appropriate washing program can be selected according to different types of tableware and the degree of stains to achieve better washing results. If the tableware is large, then selecting a double-sided wash program can more comprehensively clean the inside and outside of the tableware and reduce the residual food residue and stains. This method can adapt to different types of tableware and different washing needs. For example, large baking trays, stew pots and other tableware, or tableware that needs to be cleaned particularly carefully, can achieve better washing results by automatically identifying and selecting washing programs. In addition, this method of automatically identifying and selecting washing programs can reduce the user's troubles in selecting washing programs, making washing simpler and more convenient.

[0053] In this embodiment, during the reservation process of the dishwasher, the dishwasher automatically adjusts the time and temperature of the reservation process according to the condition of the dishes in the washing chamber. By automatically adjusting the time and temperature of the reservation process, the dishwasher can better adapt to different types of dishes and stains and improve washing efficiency. It automatically adjusts the temperature according to the condition of the dishes to avoid damage to the dishes due to excessively high or low temperatures and protect the integrity and service life of the dishes. Automatically adjusting the time and temperature can reduce energy consumption and energy waste, and also help reduce carbon emissions, which is in line with the concept of environmental protection. Users do not need to manually set the time and temperature, which reduces the burden on users to operate the dishwasher and makes it more convenient and quick to use.

[0054] Example 2

[0055] A dishwasher is provided with a temperature sensor outside a washing chamber of the dishwasher for directly measuring the indoor temperature of a user as the temperature T outside the washing chamber.

[0056] In this embodiment, the washing chamber of the dishwasher is provided with a spray arm.

[0057] When it is determined that the volume of the dishes in the washing chamber accounts for less than or equal to the second set value, the spray arm is used to spray and wet the dishes in the washing chamber. In the present application, when it is determined that the volume of the dishes in the washing chamber accounts for less than or equal to 2 / 5 of the volume of the washing chamber, the volume of the dishes in the washing chamber is small at this time. The spray arm is used to spray and wet the dishes, and the spray intensity and range can be adjusted, which can reduce the amount of water used and achieve the purpose of saving water resources; and the spray arm can cover the dishes more comprehensively to ensure that every corner can be fully washed, which can reduce the washing time and improve the washing efficiency.

[0058] Proper use of the spray arms can help extend the life of your dishwasher because their proper operation reduces dirt and wear inside the machine, keeping it in good working condition.
