Description

Technical Field

[0001] This invention belongs to the field of household appliance technology, specifically, it relates to a dishwasher control method and a dishwasher. Background Technology

[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, and dishes. Existing dishwashers can be divided into two types: commercial dishwashers and household dishwashers. Household dishwashers mainly come in various forms such as cabinet type, countertop type, sink-integrated type, and integrated type.

[0003] With the increasing number of households using dishwashers, the arrangement of dishes during operation has a significant impact on the cleaning effect. If the dishes are placed too densely, stains are difficult to rinse off, resulting in poor cleaning and reduced cleaning quality. Currently, the density of dish placement relies on the user's judgment, which is prone to bias and makes it difficult to guarantee the cleaning effect. Therefore, this invention is proposed to address this issue.

[0004] This invention proposes a dishwasher control method. After the user places the dishes and starts the washing program, the dishwasher first controls the top spray device to spray water onto the dishes. A collection device is set at the bottom of the dishwasher to collect the water flowing in after spraying. Based on the water flow rate entering the collection device within a preset time, if the water flow rate is greater than a preset value, it means that the dishes are not placed too densely, and the washing process can begin. If the water flow rate is less than the preset value, it means that the dishes are placed too densely, and the dishwasher will automatically remind the user to adjust the placement of the dishes. This avoids the placement of the dishes affecting the washing effect and improves the cleaning effect and quality of the dishes. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and solve the problem that the dishwasher's washing effect is easily caused by the tableware being placed too densely. The present invention provides a dishwasher control method and a dishwasher.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A dishwasher control method, the dishwasher including a spray assembly and a receiving cavity, the dishwasher control method comprising:

[0008] The placement of tableware in the receiving cavity is detected, and the placement status includes at least the density of placement.

[0009] The dishwasher selects whether to start the washing process based on the arrangement of the tableware.

[0010] Furthermore, the dishwasher's ability to select whether to start the washing process based on the arrangement of the tableware includes:

[0011] If the arrangement of the tableware meets the washing requirements, the dishwasher will automatically start the washing program. If the arrangement of the tableware does not meet the washing requirements, the dishwasher will remind the user to adjust the arrangement of the tableware and will repeatedly check the arrangement of the tableware until it meets the washing requirements.

[0012] Furthermore, detecting the placement of the tableware within the receiving cavity includes:

[0013] The spray assembly performs water spray detection and collects the flow rate of the water after spraying within a preset time.

[0014] The dishwasher determines the density of the tableware arrangement in the receiving cavity based on the water flow rate. If the water flow rate is greater than a preset value, it indicates that the tableware arrangement is not dense. If the water flow rate is less than or equal to the preset value, it indicates that the tableware arrangement is too dense.

[0015] Furthermore, the preset value is either the dishwasher's factory default value or a value set by the user.

[0016] Furthermore, if the tableware is not placed too densely and meets the washing requirements of the dishwasher, the dishwasher will automatically start the washing process to wash the tableware; if the tableware is placed too densely and does not meet the washing requirements of the dishwasher, the dishwasher will remind the user to adjust the placement of the tableware and repeatedly check the placement of the tableware until it meets the washing requirements.

[0017] Furthermore, adjusting the arrangement of the tableware includes changing the placement of the tableware and / or reducing the number of tableware items.

[0018] Furthermore, a collection device for collecting spray water is provided at the bottom of the dishwasher, and a water flow detector for detecting water flow rate is provided at the collection port of the collection device.

[0019] Furthermore, the arrangement of the tableware also includes the placement of the tableware.

[0020] Furthermore, detecting the placement of the tableware includes:

[0021] Acquire images of the tableware within the receiving cavity;

[0022] The image is compared with the information stored in the dishwasher's storage unit to determine the arrangement of the tableware.

[0023] The present invention also proposes a dishwasher, wherein the dishwasher applies any of the dishwasher control methods described above.

[0024] By adopting the above technical solution, the present invention has the following beneficial technical effects compared with the prior art:

[0025] 1. This invention proposes a dishwasher control method. After the user places the tableware and starts the washing program, the dishwasher first controls the top spray assembly to spray water onto the tableware to be washed. A collection device is set at the bottom of the dishwasher to collect the water flowing in after spraying. The washing process is started based on the water flow rate entering the collection device within a preset time. If the water flow rate is greater than the preset value, it means that the tableware is not placed too densely, and the washing process can start. If the water flow rate is less than or equal to the preset value, it means that the tableware is placed too densely, and a reminder is issued to the user to adjust the tableware placement. This avoids the tableware placement affecting the washing effect and improves the cleaning effect and quality of the tableware.

[0026] 2. Users can avoid stacking tableware by changing the placement of the tableware and / or reducing the number of tableware items, so that the surface of the tableware can be thoroughly rinsed and cleaned, thereby improving cleaning efficiency and shortening cleaning time.

[0027] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0028] The accompanying drawings, as part of this invention, are used to provide a further understanding of the invention. The illustrative embodiments and descriptions of the invention are used to explain the invention, but do not constitute an undue limitation of the invention. Obviously, the drawings described below are merely some embodiments, and those skilled in the art can obtain other drawings based on these drawings without creative effort. In the drawings:

[0031] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0032] To make the objectives, 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 with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] like Figure 1 As shown, the present invention provides a dishwasher control method. The dishwasher includes a spray assembly and a receiving cavity. The dishwasher control method includes:

[0036] S1. Detect the arrangement of tableware in the receiving cavity, including at least the density of the arrangement;

[0037] S2. The dishwasher can be set to start the washing cycle based on the arrangement of the dishes.

[0038] In the dishwasher control method provided by the present invention, the dishwasher can automatically detect the placement status of the tableware in the receiving cavity, such as the density of the tableware placement, and thereby control whether to start the washing process of the dishwasher, so as to avoid the situation where the placement status does not meet the washing requirements, avoid the dishwasher operating ineffectively or inefficiently when the tableware is not properly placed, and improve the cleaning effect of the dishwasher.

[0039] In embodiments of the present invention, the arrangement of tableware includes not only the density of the arrangement but also the placement of the tableware. Generally, the denser the tableware is arranged, the more water the dishwasher needs during the spray rinsing process, and the longer the spray rinsing time. The placement of the tableware determines the spray range of the spray assembly, and also determines the position and range of the spray assembly's operation. Only when the spray range of the spray assembly covers all the tableware can all the tableware to be washed be thoroughly cleaned, avoiding secondary washing for the user and reducing user costs.

[0040] Understandably, as the core component of a dishwasher, the spray assembly in this embodiment can change its spray angle and reciprocate along a horizontal plane during operation. In other embodiments, the spray assembly can also reciprocate along a vertical plane or along circular or square trajectories. Furthermore, a detection probe can be installed in the receiving cavity to prevent the spray assembly from spraying in areas where no tableware is placed, thereby maximizing water utilization and avoiding waste.

[0041] It should be noted that there are multiple ways to detect the placement of tableware in the receiving cavity in step S1. Since the placement of tableware includes various status information such as the density of tableware placement and the placement position of tableware, different detection methods can be set for different status information of tableware that you want to obtain. For example, water spray detection can be used to detect the density of tableware placement, and image acquisition and comparison can be used to determine the placement position and / or density of tableware placement.

[0042] As attached Figure 2 As shown, in one embodiment of the present invention, detecting the placement state of tableware in the receiving cavity includes:

[0043] The spray assembly performs water spray detection and collects the flow rate of the water after spraying within a preset time.

[0044] The dishwasher determines the density of the dishes in the cavity based on the water flow rate. If the water flow rate is greater than the preset value, it means that the dishes are not placed densely. If the water flow rate is less than or equal to the preset value, it means that the dishes are placed too densely.

[0045] Furthermore, the preset values ​​are either the dishwasher's factory default values ​​or user-defined values. Regarding the specific value of the preset value, those skilled in the art can set it according to actual needs, taking into account the dishwasher's washing power and the washing capacity of the washing chamber. When the dishwasher has a higher washing power and a larger washing capacity, the preset value can be set accordingly; when the dishwasher has a lower washing power and a smaller washing capacity, the preset value can be set accordingly.

[0046] In the above embodiment, after the user places the tableware and starts the washing program, the dishwasher first controls the top spray component to spray water onto the tableware to be cleaned. A collection device is set at the bottom of the dishwasher to collect the water flowing in after spraying. The washing process is started based on the water flow rate entering the collection device within a preset time. If the water flow rate is greater than the preset value, it means that the tableware is not placed too densely, and the washing process can be started automatically. If the water flow rate is less than or equal to the preset value, it means that the tableware is placed too densely, and a reminder is issued to the user to adjust the tableware placement. This avoids the tableware placement affecting the washing effect and improves the cleaning effect and quality of the tableware.

[0047] As another embodiment of the present invention: detecting the placement status of tableware includes:

[0048] Acquire images of the tableware within the receiving cavity;

[0049] The image is compared with the information stored in the dishwasher's storage unit to determine the arrangement of the tableware.

[0050] The captured images are compared with image information stored in the dishwasher's storage unit to determine the arrangement of the tableware, including the position or density of the tableware. Optionally, the dishwasher's storage unit stores image information corresponding to different tableware arrangements before it leaves the factory, or the user inputs image information into the storage unit after the dishwasher leaves the factory; alternatively, the storage unit automatically updates downloaded image information using a network system. By comparing the captured images with the stored image information, the arrangement of the tableware can be confirmed.

[0051] Furthermore, the dishwasher selects whether to start the washing cycle based on the arrangement of the dishes, including:

[0052] If the arrangement of the tableware meets the washing requirements, the dishwasher will automatically start the washing cycle. If the arrangement of the tableware does not meet the washing requirements, the dishwasher will remind the user to adjust the arrangement of the tableware and will repeatedly check the arrangement of the tableware until it meets the washing requirements.

[0053] During the dishwashing process, proper placement of the dishes can quickly remove stains or food residue from the surface and ensure that the sprayed water reaches every part of the dishes for cleaning. If the dishes are stacked or placed too close together, it will be difficult to remove stains between the dishes, which not only wastes a lot of water resources but also makes it difficult to achieve the desired dishwashing effect and reduces cleaning efficiency.

[0054] It should be noted that adjusting the arrangement of the tableware in the above embodiments includes changing the placement of the tableware and / or reducing the number of tableware pieces.

[0055] Users can avoid stacking tableware by changing the placement of the tableware and / or reducing the number of tableware items, so that the surface of the tableware can be thoroughly rinsed and cleaned, improving cleaning efficiency and shortening cleaning time.

[0056] It should be further explained that when the arrangement of tableware does not meet the washing requirements, the dishwasher will remind the user in several ways. For example, it can remind the user through a beeping sound, a whistle, or other specific music; or it can remind the user through specific voice prompts such as "Tableware not arranged properly" or "Tableware too densely packed" to remind the user to adjust the arrangement of the tableware in time.

[0057] As an embodiment of the present invention, the dishwasher control method specifically includes the following steps:

[0058] S100, The program starts, the spray assembly performs water spray detection, and collects the flow rate of the water after spraying within a preset time.

[0059] S101. The dishwasher determines the density of the tableware in the receiving cavity based on the water flow rate. If the water flow rate is greater than the preset value, it means that the tableware is not densely packed. If the water flow rate is less than or equal to the preset value, it means that the tableware is too densely packed.

[0060] S102. If the tableware is not placed too densely, it proves that the tableware placement meets the washing requirements, and the dishwasher will automatically start the washing process; if the tableware is placed too densely, it proves that the tableware placement does not meet the washing requirements, and the dishwasher will remind the user to adjust the tableware placement and repeat the above steps S100-S101 until the tableware placement meets the washing requirements.

[0061] By conducting a water spray test before starting the washing cycle to determine the water flow rate, it is possible not only to detect and determine the density of the tableware, but also to pre-wash the tableware, ensuring that the number and placement of tableware in the dishwasher are appropriate, reducing the amount of spray water used, promoting faster cleaning of tableware, and improving the dishwasher's operating efficiency and quality.

[0062] In another embodiment of the present invention, the dishwasher control method specifically includes the following steps:

[0063] S100, The program starts and acquires images of the tableware inside the receiving cavity;

[0064] S101. Compare the image with the information stored in the dishwasher's storage unit to determine the placement of the tableware.

[0065] S102. If the arrangement of the tableware meets the washing requirements, the dishwasher will automatically start the washing process. If the arrangement of the tableware does not meet the washing requirements, the dishwasher will remind the user to adjust the arrangement of the tableware and repeat steps S100-S101 until the arrangement of the tableware meets the washing requirements.

[0066] By using image acquisition and image comparison within the dishwasher system, the placement of tableware is determined. If the placement meets the washing requirements (e.g., no tableware is stacked and there are reasonable gaps between tableware), the dishwasher automatically starts the washing process and proceeds to the next stage of tableware processing. If the placement does not meet the washing requirements, the dishwasher sends a reminder to the user. After receiving the reminder, the user adjusts the placement of the tableware, and then repeats the detection steps S100-S101 until the washing requirements are met before automatically resuming the washing process. This improves the cleaning effect and quality of the tableware, avoids secondary cleaning, and prevents resource waste.

[0067] The present invention also proposes a dishwasher that applies the dishwasher control method described in any of the above embodiments.

[0068] Furthermore, a collection device for collecting spray water is provided at the bottom of the dishwasher, and a water flow detector for detecting water flow rate is provided at the collection port of the collection device.

[0069] In this invention, a collection device is used to determine the flow rate of the water returning after spraying. If the flow rate is greater than a preset value within a preset time range, it indicates that the dishes inside the dishwasher are not densely packed, and the washing process can be started. If the flow rate is less than or equal to the preset value, it indicates that the dishes inside the dishwasher are too densely packed, and water remains on the dishes. In this case, the dishwasher will automatically remind the user to adjust the arrangement of the dishes to avoid affecting the washing effect and reducing the cleaning quality of the dishes.

[0070] Compared with the prior art, the technical solutions in the above embodiments of the present invention have the following beneficial technical effects:

[0071] 1. This invention proposes a dishwasher control method. After the user places the dishes and starts the washing program, the dishwasher first controls the top spray component to spray water onto the dishes to be cleaned. A collection device is set at the bottom of the dishwasher to collect the water flowing in after spraying. The washing process is started based on the water flow rate entering the collection device within a preset time. If the water flow rate is greater than the preset value, it means that the dishes are not placed too densely, and the washing process can start. If the water flow rate is less than or equal to the preset value, it means that the dishes are placed too densely, and a reminder is issued to the user to adjust the placement of the dishes. This avoids the placement of the dishes affecting the washing effect and improves the cleaning effect and quality of the dishes.

[0072] 2. Users can avoid stacking tableware by changing the placement of the tableware and / or reducing the number of tableware items, so that the surface of the tableware can be thoroughly rinsed and cleaned, thereby improving cleaning efficiency and shortening cleaning time.
