Description

Technical Field

[0001] This invention relates to the field of dishwasher technology, and in particular to a dishwasher control method and a dishwasher. Background Technology

[0002] A dishwasher is a common kitchen appliance whose main function is to clean dishes. During use, a dishwasher typically goes through several stages, including pre-wash, main wash, rinsing, and drying. The drying stage involves heating air with a heater, then using a fan to blow the hot air onto the dishes to achieve the desired dryness. After the rinsing stage, the dishwasher enters the drying stage. Users can manually open the door or use an automatic door opener to release steam and improve drying efficiency. However, when the dishwasher opens automatically, a large amount of steam diffuses to the surrounding area and upwards. This steam can affect the cabinet containing the dishwasher and surrounding appliances. Over time, this can cause the cabinet to crack or rust, and damage nearby appliances, impacting the user experience. Furthermore, if someone is nearby when the door opens automatically, there is a risk of burns. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a control method for a dishwasher and a dishwasher, so that when the dishwasher door is opened during the drying stage, baffles extend from the top and sides of the dishwasher to block hot and humid gas, preventing the cabinets around the dishwasher from cracking and the appliances from being damaged by the hot gas, and avoiding a large amount of hot gas surging outwards and scalding the user. This can ensure the drying effect of the dishwasher without affecting the surrounding cabinets and appliances.

[0004] In a first aspect, embodiments of the present invention provide a control method for a dishwasher. The dishwasher is equipped with a telescopic baffle, which is used to guide hot air overflowing from the dishwasher door to a designated location. The method includes: when the dishwasher enters the drying stage, detecting whether there is a human body within a preset safe distance range of the dishwasher using a human body detection module; if not, determining the extension length of the baffle and the opening time of the dishwasher door based on the internal temperature of the dishwasher, and determining the opening angle of the door based on the extension length of the baffle; opening the door to the opening angle and extending the baffle to the extension length using an automatic door opening and closing module; and closing the door after the door opening time reaches the opening time.

[0005] In an optional embodiment of this application, the baffle is disposed on the top of the dishwasher; or, the baffle is disposed on the top and both sides of the dishwasher.

[0006] In optional embodiments of this application, the baffle is made of a material that deforms under stress, recovers its original shape when there is no external force, and can be reused repeatedly; or, the baffle is made of a material that deforms when exposed to water, recovers its original shape in a dry environment, and can be reused repeatedly.

[0007] In an optional embodiment of this application, after the step of detecting whether a human body is within the preset safe distance range of the dishwasher by the human body detection module, the method further includes: if so, determining the moment when a human body is detected within the safe distance range as a first moment; after the human body moves away from the dishwasher, determining the moment when no human body is detected within the safe distance range as a second moment; determining the time from the first moment to the second moment as the door opening delay time; and determining whether to open the door through the automatic door opening and closing module based on the door opening delay time.

[0008] In an optional embodiment of this application, the step of determining whether to open the door through the automatic door opening and closing module based on the door opening delay time includes: obtaining the remaining time of the dishwasher's washing program and determining the time difference between the remaining time and the door opening delay time; if the time difference is greater than a preset time threshold, opening the door to the opening angle and extending the baffle to the extension length through the automatic door opening and closing module; if the time difference is less than or equal to the time threshold, keeping the door closed.

[0009] In an optional embodiment of this application, the steps of determining the extension length of the baffle and the opening time of the dishwasher door based on the internal temperature of the dishwasher include: obtaining a preset internal reference temperature, an initial opening time, and an initial extension length of the dishwasher; determining the temperature difference between the internal temperature of the dishwasher and the internal reference temperature; determining the change in opening time and the change in extension length based on the temperature difference; determining the opening time of the dishwasher door based on the initial opening time and the change in opening time; and determining the extension length of the baffle based on the initial extension length and the change in extension length.

[0010] In an optional embodiment of this application, after determining the door opening angle based on the extension length of the baffle, the method further includes: if the internal temperature of the dishwasher is less than or equal to a preset temperature threshold, maintaining the door opening angle unchanged; if the internal temperature of the dishwasher is greater than the temperature threshold, adjusting the door opening angle based on the internal temperature. In an optional embodiment of this application, the step of adjusting the door opening angle based on the internal temperature includes: determining the temperature difference between the internal temperature of the dishwasher and the temperature threshold; determining the change in the opening angle based on the temperature difference; and adjusting the door opening angle based on the change in the opening angle.

[0011] In an optional embodiment of this application, after the steps of determining the extension length of the baffle and the opening time of the dishwasher door based on the internal temperature of the dishwasher, and determining the opening angle of the door based on the extension length of the baffle, the method further includes: if the extension length of the baffle is greater than or equal to a preset extension length threshold, determining the extension length of the baffle as a preset maximum extension length; if the opening angle of the door is greater than or equal to a preset opening angle threshold, determining the opening angle of the door as a preset maximum opening angle.

If not, the extension length of the baffle and the opening time of the dishwasher door are determined based on the internal temperature of the dishwasher. The opening angle of the door is determined based on the extension length of the baffle. An automatic door opening and closing module opens the door to the opening angle and extends the baffle to its extension length. After the door has been open for the required duration, the automatic door opening and closing module closes the door. In this method, when the dishwasher door is opened during the drying stage, baffles extend from the top and sides to block hot and humid air, preventing cracking of cabinets and damage to appliances around the dishwasher caused by hot air, and avoiding scalding of users by large amounts of hot air. This ensures the drying effect of the dishwasher without affecting surrounding cabinets and appliances.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Currently, with the continuous improvement of social technology, integrated whole-house customization and a wide variety of kitchen appliances have greatly improved people's quality of life. However, due to limited kitchen space, dishwashers are usually built into cabinets, leaving room for more expensive cabinets and other kitchen appliances. (See also...) Figure 1 The diagram shown is of an existing dishwasher and Figure 2 The diagram shows a steam flow pattern in an existing dishwasher. When the dishwasher is in the drying process, whether the user manually opens the door or the dishwasher has an automatic door opening function, the overflowing high-humidity and high-heat steam will condense on the cabinets and appliances around the dishwasher. Over time, this can cause the cabinets to become damp and deformed, and the appliances to be damaged, resulting in a poor user experience.

[0029] Existing dishwashers have the following drawbacks during the drying stage:

[0030] (1) When the dishwasher is in the drying stage, the steam diffuses upwards and affects the surrounding cabinets and appliances above, as well as the users around the dishwasher;

[0031] (2) If an air duct assembly is added to the top of the dishwasher's inner tub to blow out heat, it cannot effectively blow the steam away from the appropriate distance, and the steam will still affect the surrounding cabinets and the appliances above.

[0032] (3) If the dishwasher door opens automatically without warning during the drying stage, people around the dishwasher may be burned.

[0033] Based on this, the present invention provides a control method and a dishwasher for a dishwasher, specifically a steam diversion control method and a dishwasher that can be applied to the drying stage of the dishwasher. This effectively solves problems such as cabinet deformation, appliance damage, and user burns caused by steam overflow during the drying stage, without affecting the appearance and ease of use of the dishwasher, when the user manually opens the door or the dishwasher opens the door automatically. For different types of dishwashers, such as built-in dishwashers, corresponding air outlet devices or baffles can be designed.

[0034] To facilitate understanding of this embodiment, a dishwasher control method disclosed in this embodiment of the invention will first be described in detail.

[0035] Example 1:

[0036] This invention provides a control method for a dishwasher, wherein the dishwasher is equipped with a telescopic baffle, which is used to guide the hot air overflowing from the dishwasher door to a designated position.

[0037] In this embodiment, a telescopic baffle can be provided for the dishwasher. The baffle can guide the hot air overflowing from the dishwasher door to a designated position a certain distance away from the cabinet where the dishwasher is located. For example, the upper baffle extends 10-50cm.

[0038] The selection of the designated location should take into account its impact on the surrounding environment and the smoothness of heat dissipation. The location should be chosen away from cabinets and appliances to avoid impacting the surrounding environment, such as causing poor airflow or affecting the even distribution of indoor temperature.

[0039] In some embodiments, the baffle is disposed on the top of the dishwasher; or, the baffle is disposed on the top and both sides of the dishwasher.

[0040] See also Figure 3 The diagram shows a dishwasher with a top baffle. In this embodiment, a top telescopic baffle 1 can be added to the top of the dishwasher. The baffle 1 can be extended and retracted by a push rod motor 2.

[0041] See also Figure 4The diagram shows a dishwasher with baffles on the top and sides. In this embodiment, U-shaped telescopic baffles 1 can also be added to the top and sides of the dishwasher. The U-shaped baffles 1 can be one piece or two pieces. The two pieces of baffles are composed of an upper baffle 11, a left baffle 12 and a right baffle 13.

[0042] In some embodiments, the baffle is made of a material that deforms under stress, recovers its original shape when there is no external force, and can be reused repeatedly; or, the baffle is made of a material that deforms when exposed to water, recovers its original shape in a dry environment, and can be reused repeatedly.

[0043] In this embodiment, the baffle can be an irregularly shaped baffle, for example, the top baffle can be set as an irregularly shaped baffle. The material of the irregularly shaped baffle is deformable under force, can return to its original shape when no external force is applied, and can be reused, such as rubber. Alternatively, it can be a material that can deform when exposed to water, can return to its original shape in a dry environment, and can be reused, such as silicone. The shape of the irregularly shaped baffle can be changed according to the amount of hot air to adapt to different amounts of hot air.

[0044] In summary, the baffle design in this embodiment ensures effective heat blocking without affecting the overall appearance of the dishwasher. The shape and size of the baffle are designed based on the dishwasher's workload and the amount of heat generated, ensuring complete heat blockage even under conditions of high workload and high heat generation.

[0045] It should also be noted that although the dishwasher in this embodiment has an additional baffle, the appearance of the dishwasher in the closed state is the same as that of the original dishwasher. (See also...) Figure 5 This is a schematic diagram showing the appearance of a dishwasher in the closed state.

[0046] In summary, this embodiment provides a dishwasher that prevents hot air overflowing during the drying stage from causing cabinet deformation, appliance damage, and burns. For example, a built-in dishwasher measures 597mm in length, 570mm in width, and 800mm in height, weighing 70kg. A baffle is added to the top of the dishwasher. This baffle is 590mm long and 560mm wide, made of lightweight aluminum alloy, and is fixed to the top of the dishwasher using a slot. The baffle design should consider its impact on the dishwasher's internal space and usability, and be easy to install and use. The baffle opens automatically when the dishwasher begins the drying stage. At this time, the overflowing gas is guided outside the cabinet where the dishwasher is located through an air vent device, thus preventing the gas from affecting the cabinet and appliances. A human detection module can also detect whether to delay the door opening, effectively preventing burns to people around the dishwasher. This effectively solves the problems of cabinet deformation, appliance damage, and burns caused by hot air overflowing during the drying stage.

[0047] Based on the above description, please refer to Figure 6 The flowchart shown illustrates a control method for a dishwasher, which includes the following steps:

[0048] Step S602: When the dishwasher enters the drying stage, the human body detection module detects whether there is a human body within the preset safe distance range of the dishwasher.

[0049] The dishwasher in this embodiment may include: a control module, a human body detection module mounted on the door panel, and an automatic door opening / closing module. The control module is connected to both the human body detection module and the automatic door opening / closing module. The control module can control the operation or shutdown of both the human body detection module and the automatic door opening / closing module.

[0050] See also Figure 7 The diagram illustrates a control method for a dishwasher. When the dishwasher enters the drying stage of the washing program, it checks whether the automatic door opening time has been reached according to the program settings. If the automatic door opening time has not been reached, the detection continues. If the automatic door opening time has been reached, the human body detection module (which can be a human body sensor) starts working and determines whether there are people around the dishwasher, i.e., whether there are people within the dishwasher's preset safe distance range, based on the collected information.

[0051] Step S604: If not, determine the extension length of the baffle and the opening time of the dishwasher door based on the internal temperature of the dishwasher, and determine the opening angle of the door based on the extension length of the baffle.

[0052] like Figure 7 As shown, if no human body is present within the dishwasher's preset safe distance range, it is determined that no one is around the dishwasher, and the automatic door opening action is executed. Prior to executing the automatic door opening action, this embodiment can determine the baffle extension length and the dishwasher door opening time based on the dishwasher's internal cavity temperature, and determine the door opening angle based on the baffle extension length.

[0053] By calculating the baffle extension length, door opening time, and door opening angle using the above methods, the dishwasher can achieve better hot air flow and drying effects.

[0054] Step S606: Open the door to the opening angle using the automatic door opening and closing module, and extend the baffle to the extension length; after the door has been open for the required duration, close the door using the automatic door opening and closing module.

[0055] like Figure 7As shown, after determining the baffle extension length, door opening duration, and door opening angle, the automatic door opening module can open the door to the opening angle and extend the baffle to its extension length. Hot air can escape from the door and be guided to a designated location by the baffle. After the door has been open for the required duration, the automatic door opening module can close the door, thus ending the drying phase of the dishwasher's washing program.

[0056] This invention provides a control method for a dishwasher. When the dishwasher enters the drying stage, a human detection module detects whether a human is within a preset safe distance range. If not, the extension length of the baffle and the opening time of the dishwasher door are determined based on the internal temperature of the dishwasher. The opening angle of the door is determined based on the extension length of the baffle. An automatic door opening and closing module opens the door to the opening angle and extends the baffle to its extension length. After the door has been open for the required duration, the automatic door opening and closing module closes the door. In this method, when the dishwasher door is opened during the drying stage, baffles extend from the top and sides to block hot and humid air, preventing cracking of cabinets and damage to appliances around the dishwasher caused by the hot air, and avoiding scalding of users by large amounts of hot air. This ensures the drying effect of the dishwasher without affecting surrounding cabinets and appliances.

[0057] Example 2:

[0058] This invention provides a dishwasher control method, which can be implemented based on the aforementioned embodiments. This embodiment focuses on describing the situation where a human body detection module detects that no human body is within the dishwasher's preset safe distance range. (See also...) Figure 8 The flowchart shown represents another control method for a dishwasher, which includes the following steps:

[0059] Step S802: When the dishwasher enters the drying stage, the human body detection module detects whether there is a human body within the preset safe distance range of the dishwasher.

[0060] Step S804: If yes, determine the moment when a human body is detected within a safe distance as the first moment.

[0061] like Figure 7 As shown, if a person is within the dishwasher's preset safe distance, it is determined that someone is around the dishwasher, and the automatic door opening action needs to be delayed. First, the moment when someone is detected can be determined as the first moment.

[0062] Step S806: After the human body moves away from the dishwasher, the moment when no human body is detected within the safe distance range is defined as the second moment.

[0063] After detecting someone, the detection can continue until no one is detected, meaning no human body is within a safe distance. At this point, it can be determined that the person is away from the dishwasher. Figure 7 As shown, if the first moment is not cleared, detection can continue until no one is detected, and the moment when no one is detected is determined as the second moment.

[0064] Step S808: Determine the time from the first moment to the second moment as the door opening delay time.

[0065] like Figure 7 As shown, after determining the first moment and the second moment, the time from the first moment to the second moment can be determined as the door opening delay time, which is the duration of the human body around the dishwasher.

[0066] Step S810: Determine whether to open the door via the automatic door opening / closing module based on the door opening delay time.

[0067] This embodiment can determine whether the door needs to be opened further based on the door opening delay, that is, whether to open the door through the automatic door opening and closing module.

[0068] In some embodiments, the remaining time of the dishwasher's washing program can be obtained, and the time difference between the remaining time and the door opening delay time can be determined. If the time difference is greater than a preset time threshold, the door can be opened to the opening angle and the baffle can be extended to the extension length via the automatic door opening and closing module. If the time difference is less than or equal to the time threshold, the door can be kept closed.

[0069] like Figure 7 As shown, this embodiment can obtain the remaining time of the dishwasher's washing program and calculate the time difference between the remaining time and the door opening delay time. The preset time threshold X can be represented as the time required for the door to open and dry.

[0070] like Figure 7 As shown, if the time difference is greater than the preset time threshold X, it can be considered that the remaining time minus the door opening delay time still has enough time for the door to open and dry, and the steps of opening the door to the opening angle and extending the baffle to the extension length by the automatic door opening and closing module can be performed.

[0071] like Figure 7 As shown, if the above time difference is less than or equal to the preset time threshold X, it can be considered that the remaining time minus the door opening delay time is insufficient for the door to open for drying. In this case, the door can be kept closed and the door can no longer be opened for drying.

[0072] The method provided in this embodiment of the invention can determine whether the remaining time of the washing program minus the door opening delay time is greater than the time threshold X required for the door to open for drying, thereby making a delayed door opening judgment when there are people around the dishwasher.

[0073] The method provided in this embodiment of the invention involves a human body detection module on the dishwasher door collecting information and reporting it to the control module. The control module then determines whether to open or close the door based on the reported information. The human body detection module can operate at different times depending on the program stage. It does not work during the non-drying stage, but starts working during the drying stage when an automatic door opening signal is detected.

[0074] Once the dishwasher is in the drying stage, it will automatically open the door and open the baffle as set in the program when it detects that no one is around. After the door opening time in the drying stage reaches the set value, the door will close and the program will continue or the dishwasher will turn off.

[0075] Once the dishwasher is in the drying phase, if it detects someone nearby, it delays the door opening time. If someone remains at a non-safe distance from the dishwasher, the dishwasher keeps the door closed or prompts the user, "The door is about to open, please move away from the dishwasher," until the user leaves, at which point it will then open the door and extend the baffle. If the detected person is within the safe distance of the dishwasher, it executes the door opening logic and simultaneously provides a voice prompt to the user that the door is about to open.

[0076] Example 3:

[0077] This invention provides a control method for a dishwasher, which can be implemented based on the aforementioned embodiments. This embodiment focuses on describing the specific method of determining the extension length of the baffle and the opening time of the dishwasher door based on the internal temperature of the dishwasher, as well as the specific method of adjusting the opening angle of the door based on the internal temperature.

[0078] In this embodiment, the door opening time and the baffle extension length can vary according to different internal cavity temperatures. If the opening time is reached and the internal cavity temperature is lower than the preset internal cavity reference temperature, the door will not open. If the opening time is reached and the internal cavity temperature is higher than or equal to the preset internal cavity reference temperature, the door can be opened according to the program settings.

[0079] In this embodiment, the extension length of the baffle can be determined based on the temperature difference between the inner cavity temperature and the inner cavity reference temperature. The opening angle can be adapted to the extension length of the baffle to achieve dynamic control of the opening angle. At the same time, the opening angle can also be adjusted according to the inner cavity temperature. The preset values ​​of the baffle extension length and the opening angle are determined based on a certain temperature, and the extension length of the baffle and the opening angle are dynamically adjusted according to the actual inner cavity temperature.

[0080] In some embodiments, the dishwasher's preset cavity reference temperature, initial door opening time, and initial extension length can be obtained; the temperature difference between the dishwasher's cavity temperature and the cavity reference temperature can be determined; the change in door opening time and the change in extension length can be determined based on the temperature difference; the door opening time of the dishwasher can be determined based on the initial door opening time and the change in door opening time; and the extension length of the baffle can be determined based on the initial extension length and the change in extension length.

[0081] For example, with the internal cavity temperature of 45°C as the reference temperature, the initial door opening time is 10 minutes and the initial extension length is 15 cm. When the temperature increases by 3°C, the door opening time increases by 2 minutes and the baffle extension length increases by 1 cm.

[0082] In some embodiments, if the extension length of the baffle is greater than or equal to a preset extension length threshold, the extension length of the baffle is determined to be the preset maximum extension length; if the opening angle of the door is greater than or equal to a preset opening angle threshold, the opening angle of the door is determined to be the preset maximum opening angle.

[0083] In this embodiment, an extension length threshold and an opening angle threshold can also be set. If the extension length of the baffle is greater than or equal to the extension length threshold, it can be determined that the baffle extends at its maximum extension length; if the opening angle is greater than or equal to the preset opening angle threshold, it can be determined that the door opens at its maximum opening angle.

[0084] In some embodiments, if the internal temperature of the dishwasher is less than or equal to a preset temperature threshold, the door opening angle remains unchanged; if the internal temperature of the dishwasher is greater than the temperature threshold, the door opening angle is adjusted based on the internal temperature.

[0085] In this embodiment, the correspondence between the extension length of each baffle and the corresponding door opening angle can be preset, while reserving an angle margin and setting a maximum door opening angle. When the dishwasher is ready to open, it can automatically adapt to the preset recommended door opening angle based on the actual extension length of the current baffle. The internal temperature of the dishwasher can be monitored. If the internal temperature (which can be calculated based on the heat dissipation efficiency) is less than or equal to a preset temperature threshold, the door will open at the recommended opening angle to ensure that at least a basic heat dissipation effect is achieved.

[0086] If the internal temperature exceeds the temperature threshold, a dynamic adjustment strategy is required, which involves adjusting the door opening angle based on the internal temperature.

[0087] In some embodiments, the temperature difference between the dishwasher's internal cavity temperature and a temperature threshold can be determined; the change in the door opening angle can be determined based on the temperature difference; and the door opening angle can be adjusted based on the change in the door opening angle.

[0088] In this embodiment, the door opening angle can be gradually increased in fixed angular increments X (e.g., 5°C or other values ​​set according to specific circumstances) until a balance point is reached that efficiently exhausts heat without wasting excessive energy. The impact of increasing the door opening angle on the rate of temperature decrease in the cavity can be continuously evaluated. If the calculated door opening angle, increasing in increments, exceeds the preset maximum opening angle limit, the door opening angle will be the preset maximum value to avoid inconvenience or safety hazards caused by excessive door opening. Through the above intelligent control logic, the dishwasher can flexibly adapt to different usage scenarios and conditions, ensuring smooth exhaust of heat from the cavity while optimizing energy use and improving the user experience.

[0089] The dishwasher control method provided in this embodiment of the invention can collect information about the area around the dishwasher through a human detection module on the door to determine whether there are people around, thereby preventing scalding of people near the dishwasher. A telescopic baffle is also provided to prevent steam from directly escaping upwards; the baffle changes the direction of steam movement, thus protecting cabinets and appliances around the dishwasher from damage. The extension length of the baffle and the opening duration of the door can be determined based on the internal cavity temperature, and the opening angle of the door can be determined based on the extension length of the baffle, allowing the dishwasher to have better heat dissipation and drying effects. A maximum extension length and a maximum opening angle are also provided to avoid inconvenience or safety hazards that may result from the door opening too wide.

[0090] The dishwasher control method provided in this embodiment of the invention has the following advantages:

[0091] 1. Optimized design: By adding a baffle on top of the dishwasher, the gas is directed to a certain distance from the cabinet where the dishwasher is located, which effectively solves the problem of deformation of surrounding cabinets and damage to electrical appliances caused by air overflow when the dishwasher is opened, without affecting the appearance and ease of use of the dishwasher.

[0092] 2. Comprehensive protection: It can not only effectively divert large amounts of high-temperature and high-humidity gas that overflows in a short time, but it can also adapt to various types of dishwashers, including built-in dishwashers, providing more comprehensive protection and avoiding damage to cabinets and appliances caused by gas overflow.

[0093] 3. Improved durability: It can reduce damage to cabinets and appliances caused by gas leakage, thereby improving the durability of dishwashers and surrounding equipment, extending their service life, and reducing maintenance costs.
