Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to a dishwasher, a dishwasher control method, and a device. Background Technology

[0002] Users who don't frequently cook in the kitchen due to business trips, vacations, or other factors often have low dishwasher usage, creating a significant need for proper dish storage after washing. Most dishwashers on the market offer 72-hour or 168-hour storage functions to dry and preserve washed dishes. However, the storage phase in existing dishwashers simply follows a preset program, controlling the fan to operate. This lack of adaptability and matching to actual usage environments results in inconsistent humidity levels inside the dishwasher, leading to bacterial growth and poor dish storage capabilities.

[0003] A small number of dishwasher models on the market are equipped with a humidity sensor, which can detect the humidity of the dishwasher's inner drum and adjust the drying logic in real time based on the detection results to ensure that the humidity inside the dishwasher is maintained below a certain level.

[0004] However, the accuracy of using humidity sensors to detect the humidity inside a dishwasher is currently low. Summary of the Invention

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments 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.

[0024] Example 1

[0025] Currently, humidity sensors are installed inside the dishwasher's inner tub. During the washing process, they are easily covered with water droplets, or when the humidity inside the dishwasher is too high, condensation easily forms on the sensor's surface, severely affecting the sensor's detection accuracy. The presence of water droplets on the humidity sensor means that the humidity value detected by the sensor does not reflect the actual humidity inside the dishwasher's inner tub, resulting in low accuracy for the humidity sensor.

[0026] Based on this, Embodiment 1 of the present invention provides a control method for a dishwasher. Figure 1 This is a flowchart illustrating the dishwasher control method in Embodiment 1 of the present invention, as shown below. Figure 1 As shown, the dishwasher control method of Embodiment 1 of the present invention includes the following steps:

[0027] S101: Obtain the first humidity value detected by the humidity sensor.

[0028] Specifically, the first humidity value can be obtained by using a humidity sensor installed in the inner liner.

[0029] S102: When the first humidity value is greater than or equal to a preset first humidity threshold, a first dehumidification device for removing moisture from the surface of the humidity sensor is activated.

[0030] It should be noted that in the embodiments of the present invention, humidity refers to relative humidity, and the unit is RH.

[0031] Specifically, the first humidity threshold can be different for humidity sensors with different accuracies. For example, for a humidity sensor with an accuracy of 1%, the first humidity threshold is 99%, while for a humidity sensor with an accuracy of 0.1%, the first humidity threshold is 99.9%. This is because when the humidity sensor is covered with water droplets, the humidity is already at its highest, reaching saturation.

[0032] Furthermore, when the first humidity value is less than the first humidity threshold, the first humidity value is used as the accurate humidity value detected by the humidity sensor.

[0033] In other words, when the first humidity value is greater than or equal to the first humidity threshold, the first dehumidification device for removing moisture from the surface of the humidity sensor needs to be activated to eliminate the situation where water droplets are attached to the surface of the humidity sensor; when the first humidity value is less than the first humidity threshold, it can be determined that there are no water droplets attached to the surface of the humidity sensor, so the first humidity value detected by it is the accurate humidity value.

[0034] S103: When the working time of the first dehumidification device reaches the preset first time threshold, the second humidity value detected by the humidity sensor is obtained.

[0035] This is because, under normal circumstances, the water droplets on the surface of the humidity sensor can be dried when the first dehumidifier operates for a preset first time threshold. The first time threshold can be adjusted according to the power of the first dehumidifier, the installation location of the first dehumidifier, etc.

[0036] S104: When the second humidity value is less than the first humidity threshold, the second humidity value is used as the accurate humidity value detected by the humidity sensor.

[0037] When the second humidity value is less than the first humidity threshold, it means that the water droplets on the surface of the humidity sensor have been dried. At this time, the second humidity value detected by the humidity sensor is the accurate humidity value detected by the humidity sensor.

[0038] Furthermore, when the second humidity value is less than the first humidity threshold, the first dehumidification device needs to be controlled to stop working.

[0039] Of course, in some cases, even if the first dehumidifier operates for a preset first time threshold, it may not be able to dry the water droplets on the surface of the humidity sensor. For example, if there are many water droplets, the first dehumidifier may only blow away some of the water droplets after operating for the first time; or, after the water droplets are blown away, a small portion of water droplets may fall back onto the humidity sensor. In this case, the second humidity value detected by the humidity sensor will still be greater than or equal to the preset first humidity threshold.

[0040] Therefore, further, the dishwasher control method of Embodiment 1 of the present invention further includes: when the second humidity value is greater than or equal to the first humidity threshold, controlling the first dehumidification device to continue working; when the working time of the first dehumidification device reaches a preset second duration threshold, acquiring the third humidity value detected by the humidity sensor; and using the third humidity value as the accurate humidity value detected by the humidity sensor. Wherein, the second duration threshold is greater than the first duration threshold.

[0041] Furthermore, when the working time of the first dehumidifier reaches a preset second time threshold, the first dehumidifier is controlled to stop working.

[0042] In other words, when the first dehumidifier reaches its first time threshold, it is sufficient to dry the water droplets. The first dehumidifier continues to operate until it reaches the second time threshold to improve detection accuracy and prevent accidental failure to dry the water in one cycle, which could lead to a false judgment that the dishwasher's interior humidity is too high. Specifically, if the humidity decreases after the first dehumidifier operates once (corresponding to the first time threshold) or twice (corresponding to the second time threshold), it indicates that the water droplets on the humidity sensor's surface have dried, and the humidity sensor has returned to normal operation. If the humidity fails to decrease after the first dehumidifier operates twice, it indicates that the humidity inside the dishwasher is indeed too high, and the high humidity value is not due to water droplets on the humidity sensor's surface.

[0043] Furthermore, after using the first humidity value, the second humidity value, or the third humidity value as the accurate humidity value detected by the humidity sensor, the method further includes: when the accurate humidity value is greater than a preset second humidity threshold, activating a second dehumidification device to dehumidify the inner tub of the dishwasher. Specifically, the second humidity threshold can be determined according to the drying control program in the dishwasher. Thus, when the humidity inside the dishwasher is high, the second dehumidification device (humidification reduction device) can be activated to reduce the humidity inside the dishwasher cavity.

[0044] For example, such as Figure 2 As shown, this is a method to improve the accuracy of humidity detection. When the humidity sensor detects that the humidity in the dishwasher cavity is greater than 99%, it assigns a value of N=1, meaning the hot air fan runs once and operates for a period of time t0 (t0 is equivalent to the first time threshold). After the operation, it continues to detect the humidity in the cavity. If the detected humidity is still greater than 99%, it assigns a value of N=2, meaning the hot air fan runs twice and operates again for a period of time t0 (t0+t0 is equivalent to the second time threshold). If the detected humidity is less than 99%, it indicates that the hot air has dried the water droplets on the surface of the humidity sensor, and the humidity sensor returns to normal operation. If the hot air fan has run twice consecutively (N=2), and the detected humidity is still greater than 99%, a high humidity warning is issued, and the cavity dehumidification device is activated to dehumidify the dishwasher cavity. In short, the above logic is that when the humidity is initially detected to be greater than 99%, the hot air fan is activated to blow on the surface of the humidity sensor. After the hot air fan runs once or twice, the humidity decreases, indicating that the water droplets on the surface of the humidity sensor have been dried, and the humidity sensor returns to normal operation. If the humidity fails to decrease after the hot air blower has run twice, it indicates that the humidity inside the dishwasher is indeed too high, and it is not due to water droplets on the surface of the humidity sensor causing the humidity value to be too high. You can start the dehumidification device to reduce the humidity inside the dishwasher.

[0045] In other words, when the humidity sensor detects a humidity level greater than 99%, the hot air fan is activated to dehumidify and evaporate the water droplets on the surface of the humidity sensor, preventing inaccurate humidity readings. Once the humidity inside the dishwasher is confirmed to be greater than 99%, the dehumidification equipment is then activated to dry the interior.

[0046] Therefore, the dishwasher control method provided in Embodiment 1 of the present invention can improve the detection accuracy of the humidity sensor by using a first dehumidification device to remove water from the surface of the humidity sensor when the first humidity value detected by the humidity sensor is greater than or equal to the preset first humidity threshold. This can eliminate the situation where water droplets adhering to the surface of the humidity sensor cause the dishwasher to be mistakenly considered to have excessive humidity inside, thereby improving the detection accuracy of the humidity sensor.

[0047] Example 2

[0048] Corresponding to Embodiment 1 of the present invention, Embodiment 2 of the present invention provides a control device for a dishwasher. Figure 3 This is a schematic diagram of the dishwasher control device in Embodiment 1 of the present invention, as shown below. Figure 3 As shown, the dishwasher control device includes an acquisition module 20 and a processing module 21.

[0049] Specifically, the acquisition module 20 is used to acquire the first humidity value detected by the humidity sensor;

[0050] When the first humidity value is greater than or equal to a preset first humidity threshold, the processing module 21 is used to activate a first dehumidification device for removing moisture from the surface of the humidity sensor.

[0051] When the working time of the first dehumidification device reaches a preset first time threshold, the acquisition module 20 is further used to acquire the second humidity value detected by the humidity sensor;

[0052] When the second humidity value is less than the first humidity threshold, the processing module 21 is further configured to use the second humidity value as the accurate humidity value detected by the humidity sensor.

[0053] The dishwasher control device provided in Embodiment 2 of the present invention, when the first humidity value detected by the humidity sensor is greater than or equal to the preset first humidity threshold, utilizes a first dehumidification device for removing moisture from the surface of the humidity sensor. This can eliminate the situation where water droplets adhering to the surface of the humidity sensor are mistakenly interpreted as excessive humidity inside the dishwasher, thereby improving the detection accuracy of the humidity sensor.

[0054] Furthermore, when the second humidity value is greater than or equal to the first humidity threshold, the processing module 21 is also used to control the first dehumidification device to continue working.

[0055] When the working time of the first dehumidifier reaches the preset second time threshold, the acquisition module 20 is also used to acquire the third humidity value detected by the humidity sensor;

[0056] The processing module 21 is further configured to use the third humidity value as the accurate humidity value detected by the humidity sensor. Furthermore, when the first humidity value is less than the first humidity threshold, the processing module 21 is also configured to use the first humidity value as the accurate humidity value detected by the humidity sensor.

[0057] Furthermore, when the second humidity value is less than the first humidity threshold, the processing module 21 is also used to control the first dehumidification device to stop working.

[0058] Furthermore, when the working time of the first dehumidifier reaches a preset second time threshold, the processing module 21 is also used to control the first dehumidifier to stop working.

[0059] For specific details regarding the dishwasher control device mentioned above, please refer to the relevant documentation. Figures 1 to 2 The relevant descriptions and effects in the illustrated embodiments are for understanding purposes only and will not be repeated here.

[0060] Example 3

[0061] This invention also provides a dishwasher, which includes a humidity sensor, a first dehumidification device, and a controller. The humidity sensor is disposed at the air outlet of the dishwasher's air duct, and the first dehumidification device is disposed in the air duct. The humidity sensor, the first dehumidification device, and the controller are communicatively connected to each other.

[0062] Furthermore, the dishwasher also includes a waterproof device (4) disposed above the humidity sensor.

[0063] Furthermore, the first dehumidification device includes a hot air blower.

[0064] For example, such as Figure 4As shown, a dishwasher with improved humidity detection accuracy mainly consists of a dishwasher inner tank (2), a dish rack (3), a spray arm (7), a washing pump (10), a water cup (14), a drain pump (13), a drain pipe (12), a hot air fan (9), an air duct (8), a waterproof device (4), and a humidity sensor (6). The washing pump (10) transports the washing water collected at the bottom of the water cup (14) to the spray arm (7), and sprays it onto the surface of the tableware through the spray holes on the spray arm (7). The tableware is loaded on the dish rack (3). The drain pump (13) is connected to the water cup (14) through the drain pipe (12) to discharge the washing water after washing. The washing water is finally discharged through a U-shaped pipe (11), which mainly prevents the discharged washing water from flowing back. A humidity sensor (6) is provided on the side wall of the inner liner (2) to detect the humidity in the inner liner (2). A waterproof device (4) is wrapped above the humidity sensor (6) to prevent washing water from splashing onto the surface of the humidity sensor (6) during washing. There is an air outlet (5) inside the waterproof device (4) close to the humidity sensor (6). The air outlet (5) is connected to the air duct (8) outside the inner liner (2). There is a hot air fan (9) in the air duct (8). The hot air fan (9) provides hot air to dry the water droplets on the surface of the humidity sensor (6).

[0065] Therefore, in the dishwasher provided by this embodiment of the invention, the humidity sensor is installed on the side wall of the dishwasher's inner tub, and is covered by a waterproof device. An air outlet is located inside the sensor, connected to an external hot air fan. The waterproof device prevents water droplets from falling onto the humidity sensor during the washing process, thus avoiding detection errors.

[0066] Furthermore, a first humidity value detected by a humidity sensor is obtained; when the first humidity value is greater than or equal to a preset first humidity threshold, a first dehumidification device for removing moisture from the surface of the humidity sensor is activated; when the working time of the first dehumidification device reaches a preset first duration threshold, a second humidity value detected by the humidity sensor is obtained; when the second humidity value is less than the first humidity threshold, the second humidity value is used as the accurate humidity value detected by the humidity sensor. When the working time of the first dehumidification device reaches the preset first duration threshold, the water droplets on the surface of the humidity sensor can be dried, thereby eliminating the possibility of mistakenly believing that the humidity inside the dishwasher is too high due to water droplets adhering to the surface of the humidity sensor, thus improving the detection accuracy of the humidity sensor.

[0067] Compared to dishwashers on the market, the dishwasher of this invention can improve the detection accuracy of the humidity sensor, avoid the misinterpretation that the humidity inside the dishwasher is too high due to water droplets adhering to the sensor surface, thus activating the dehumidification equipment, avoiding power waste, extending the service life of the equipment, and improving detection accuracy.

The processor executes various functional applications and data processing by running non-transitory software programs, instructions, and modules stored in the memory, thereby implementing the dishwasher control method in the above method embodiments.

In some embodiments, the memory may optionally include memory remotely located relative to the processor, which can be connected to the processor via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.
