Abstract
Description
Technical Field
[0001] This application relates to the field of DC equipment technology, such as DC washing machines and methods and apparatus for controlling DC washing machines. Background Technology
[0002] Washing machines, as a common intelligent device for cleaning clothes, are widely used. Currently, washing machines can be powered by municipal AC power. This AC power is converted to DC power to supply the control circuit and control the operation of the washing machine. However, some electrical energy is lost during the AC-to-DC conversion process.
[0003] Furthermore, for washing machines equipped with drain pumps, if the clothes pockets are not cleaned during the washing process, the debris may flow into the drain pump inlet pipe with the water flow during drainage, causing blockage and damage to the drain pump, which in turn causes washing machine malfunction and affects the user experience. Summary of the Invention

This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0027] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.
[0028] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
[0029] Unless otherwise stated, the term "multiple" means two or more.
[0030] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.
[0031] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.
[0032] In this embodiment, the control circuit of the DC washing machine can be directly powered by DC, reducing energy loss caused by AC-to-DC conversion. Furthermore, two parallel electrode plates are attached to the outside of the drain pump inlet pipe of the DC washing machine, forming a capacitor. This allows for the acquisition of the current capacitance value of the DC washing machine capacitor and the current ambient temperature, resulting in a temperature-compensated capacitance value. If the current compensated capacitance value is greater than or equal to the blockage threshold, a blockage warning can be issued promptly. This allows for timely cleaning of debris in the drain pump inlet pipe, reducing the likelihood of blockage and further minimizing the risk of damage to the DC washing machine, thus improving the user experience.
[0033] Figure 1 This is a schematic diagram of the structure of a DC washing machine provided in an embodiment of this disclosure. Figure 1 As shown, the DC washing machine includes: an upper plate 1 and a lower plate 3 of a capacitor, and a drain pump inlet pipe 2 located between the upper plate 1 and the lower plate 3. The upper plate 1 and the lower plate 3 are parallel and can be attached to the outside of the drain pump inlet pipe 2, thus forming the capacitor in the DC washing machine.
[0034] Generally, the capacitance value of a capacitor is related to the dielectric material, relative area, and distance between the upper plate 1 and the lower plate 3. Since the two plates of the capacitor are positioned on the outside of the drain pump inlet pipe 2 and their positions are fixed (i.e., the relative area and distance between the two plates are fixed), the capacitance value can change according to the dielectric material between the two plates. Therefore, different capacitance values indicate different dielectric materials between the two plates, meaning different substances in the drain pump inlet pipe 2 of the DC washing machine. Thus, the degree of blockage in the drain pump inlet pipe can be determined based on the capacitance value, allowing for blockage alerts and reducing the likelihood of blockage.
[0035] In a DC washing machine, the drain pump inlet pipe blockage detection and control circuit can be powered by DC. Therefore, in some embodiments, the DC washing machine includes a battery that can be configured to provide DC power to the control circuit of the DC washing machine.
[0036] There are various types of storage batteries, such as lead-acid batteries and lithium iron phosphate batteries. Storage batteries can store electrical energy obtained by converting municipal AC power into DC power, or convert and store electrical energy from other energy sources. Solar energy is a clean, environmentally friendly, and sustainable energy source. In some embodiments, the DC washing machine may also include a solar energy conversion device configured to convert the acquired solar energy into electrical energy and store it in the storage battery. Therefore, converting natural, clean, and sustainable energy into electrical energy, and powering capacitors and control circuits through the storage battery, further protects the environment and reduces energy waste.
[0037] During the application of the washing machine, the degree of blockage in the drain pump inlet pipe of the DC washing machine can be determined by the change in capacitance value, and corresponding control can be performed.
[0038] Figure 2 This is a schematic flowchart illustrating a control method for a DC washing machine according to an embodiment of this disclosure. The DC washing machine includes a drain pump inlet pipe and a capacitor, wherein the two electrode plates of the capacitor are parallel and respectively attached to the outside of the drain pump inlet pipe, as shown below. Figure 2 As shown, the process for controlling a DC washing machine includes:
[0039] Step 201: Obtain the current capacitance value of the capacitor in the DC washing machine and the current ambient temperature value.
[0040] In this embodiment, a DC power supply can be provided to the control circuit of the DC washing machine. This allows for the acquisition of the capacitor's capacitance value and the monitoring of the ambient temperature surrounding the DC washing machine. The corresponding capacitance value and ambient temperature can be acquired in real-time or periodically; currently, the current capacitance value and current ambient temperature have been collected.
[0041] Step 202: Determine the current temperature compensation capacitance value that matches the current capacitance value and the current ambient temperature value, and obtain the current compensated capacitance value.
[0042] The capacitance value of a capacitor is related not only to the dielectric between the electrode plates but also to the ambient temperature, requiring corresponding temperature compensation. Therefore, the correspondence between capacitance values, temperature values, and temperature-compensated capacitance values can be stored locally or in the cloud. In some embodiments, when the drain pump inlet pipe contains debris of varying degrees of blockage, the capacitance value corresponding to each degree of blockage can be obtained; the temperature-compensated capacitance value corresponding to each capacitance value can be determined, and the correspondence between capacitance values, temperature values, and temperature-compensated capacitance values can be stored.
[0043] Multiple tests can be performed on the same model of DC washing machine to obtain the capacitance value of the capacitor corresponding to each degree of blockage. Based on the temperature compensation principle, the temperature compensation capacitor value corresponding to each capacitance value can be determined, and the correspondence between capacitance value, temperature value, and temperature compensation capacitor value can be saved. Alternatively, big data mining can be used to obtain the capacitance value of the capacitor corresponding to each degree of blockage, and based on the temperature compensation principle, the temperature compensation capacitor value corresponding to each capacitance value can be determined, and the correspondence between capacitance value, temperature value, and temperature compensation capacitor value can be saved.
[0044] Thus, after obtaining the current capacitance value and the current ambient temperature value, the current temperature compensation capacitance value can be determined based on the stored correspondence between capacitance value, temperature value, and temperature compensation capacitance value. Therefore, the current compensated capacitance value can be obtained based on the current capacitance value and the current temperature compensation capacitance value. Alternatively, in some embodiments, if the cloud server stores the correspondence between capacitance value, temperature value, and temperature compensation capacitance value, the obtained current capacitance value and current ambient temperature value can be sent to the cloud server. The cloud server can then determine and send the current temperature compensation capacitance value based on the stored correspondence. Upon receiving the current temperature compensation capacitance value, the current compensated capacitance value can be obtained based on the current capacitance value and the current temperature compensation capacitance value.
[0045] Step 203: If the current compensated capacitance value is greater than or equal to the blockage capacitance threshold, perform a blockage alert.
[0046] A blockage tolerance threshold can be preset based on the model of the DC washing machine. If the current compensated capacitance value is greater than or equal to the blockage tolerance threshold, it indicates that there is debris in the drain pump inlet pipe and it needs to be cleaned, triggering a blockage alert. The blockage alert can be triggered in several ways, including one or more methods such as text, light, and voice.
[0047] In some embodiments, the congestion alert processing includes: determining the current congestion level corresponding to the current compensated capacitance value; determining the current alert strategy corresponding to the current congestion level; and processing it.
[0048] The correspondence between capacitance value range and blockage level can be saved in advance. In this way, the current blockage level corresponding to the current compensated capacitance value can be determined based on the saved correspondence between capacitance value range and blockage level, and the current reminder strategy corresponding to the current blockage level can be executed.
[0049] For example, the capacitance value range is divided into three segments, corresponding to the highest, medium, and lowest levels of congestion. Thus, if the current congestion level corresponding to the current compensated capacitance value is the highest level, text, light, and voice alerts can be simultaneously provided, and an alert message can be sent to the matched user terminal. If the current congestion level corresponding to the current compensated capacitance value is the medium level, text and light alerts can be provided simultaneously. And if the current congestion level corresponding to the current compensated capacitance value is the lowest level, only a text alert can be provided.
[0050] In some embodiments, the capacitor of the DC washing machine is determined to be operating normally only when the capacitance value is within a set range. Therefore, it may also include: when the current compensated capacitance value is greater than or equal to the blockage capacitance threshold and less than the preset capacitance upper limit, a blockage reminder is performed, wherein the preset capacitance upper limit is greater than the blockage capacitance threshold.
[0051] Of course, if the capacitance value is not within the set range, the capacitor may be ineffective and needs to be reset. Therefore, in some embodiments, an invalid detection reminder is issued when the current compensated capacitance value is greater than or equal to the preset upper limit of capacitance, or when the current compensated capacitance value is less than or equal to the preset lower limit of capacitance; wherein, the preset lower limit of capacitance is less than the blockage capacitance threshold.
[0052] As can be seen, in this embodiment, two parallel electrode plates are attached to the outside of the drain pump inlet pipe of the DC washing machine, forming a capacitor. In this way, the current capacitance value of the DC washing machine capacitor and the current ambient temperature value can be obtained, and the current compensated capacitance value after temperature compensation can be obtained. If the current compensated capacitance value is greater than or equal to the blockage capacitance threshold, a blockage reminder can be issued in time. This allows for timely cleaning of debris in the drain pump inlet pipe, reducing the probability of blockage and further reducing the chance of damaging the DC washing machine, thus improving the user experience.
[0053] The following describes the operation process in a specific embodiment, illustrating the control process for a DC washing machine provided by the embodiments of the present invention.
[0054] In this embodiment, the DC washing machine, such as Figure 1 As shown, the device includes: an upper plate 1 and a lower plate 3 of a capacitor, and a drain pump inlet pipe 2 located between the upper plate 1 and the lower plate 3. The upper plate 1 and the lower plate 3 are parallel and can be attached to the outside of the drain pump inlet pipe 2, forming the capacitor in the DC washing machine. The control circuit of the DC washing machine is powered by DC. Furthermore, the DC washing machine has stored the correspondence between capacitance value, temperature value, and temperature compensation capacitance value, and has preset a blockage capacitance threshold Ca, a preset upper capacitance limit Cmax, and a preset lower capacitance limit Cmin.
[0055] Figure 3 This is a schematic flowchart illustrating a control method for a DC washing machine provided in an embodiment of this disclosure. (In conjunction with...) Figure 3 The process for controlling a DC washing machine includes:
[0056] Step 301: Obtain the current capacitance value Cn of the capacitor in the DC washing machine, and the current ambient temperature value.
[0057] It can acquire the current capacitance value and the current ambient temperature value at regular intervals or in real time.
[0058] Step 302: Based on the correspondence between the saved capacitance value, temperature value and temperature compensation capacitance value, determine the current temperature compensation capacitance value that matches the current capacitance value Cn and the current ambient temperature value, and obtain the current compensated capacitance value Cr.
[0059] Step 303: Determine whether the current compensated capacitance value Cr is between the preset lower limit Cmin and the preset upper limit Cmax. If yes, proceed to step 304; otherwise, proceed to step 306.
[0060] Step 304: Determine whether the current compensated capacitance value Cr is greater than or equal to the blockage capacitance threshold Ca? If yes, proceed to step 305; otherwise, the current detection and control process ends.
[0061] Step 305: Issue a blockage alert; this detection and control process is now complete.
[0062] It can provide one or more reminders, such as text, light, and voice, and can also send reminder messages to the terminal.
[0063] Step 306: Issue an invalid notification; this detection and control process is now complete.
[0064] The capacitor can be reset, but the test is ineffective.
[0065] As can be seen, in this embodiment, two parallel electrode plates are attached to the outside of the drain pump inlet pipe of the DC washing machine, forming a capacitor. In this way, the current capacitance value of the DC washing machine capacitor and the current ambient temperature value can be obtained, and the current compensated capacitance value after temperature compensation can be obtained. If the current compensated capacitance value is greater than or equal to the blockage capacitance threshold, a blockage reminder can be issued in time. This allows for timely cleaning of debris in the drain pump inlet pipe, reducing the probability of blockage and further reducing the chance of damaging the DC washing machine, thus improving the user experience.
[0066] Based on the above process for controlling a DC washing machine, a device for controlling a DC washing machine can be constructed.
[0067] Figure 4 This is a schematic diagram of a control device for a DC washing machine according to an embodiment of this disclosure. The DC washing machine includes: a drain pump inlet pipe and a capacitor, wherein the two electrode plates of the capacitor are parallel and respectively attached to the outside of the drain pump inlet pipe, as shown below. Figure 4 As shown, the DC washing machine control device is powered by DC and includes: an acquisition module 410, a determination module 420, and a first control module 430.
[0068] The acquisition module 410 is configured to acquire the current capacitance value of the capacitor in the DC washing machine and the current ambient temperature value.
[0069] The determination module 420 is configured to determine the current temperature compensation capacitance value that matches the current capacitance value and the current ambient temperature value, and to obtain the current compensated capacitance value.
[0070] The first control module 430 is configured to perform a blockage reminder when the current compensated capacitance value is greater than or equal to the blockage capacitance threshold.
[0071] In some embodiments, the system further includes: a configuration storage module configured to, when the drain pump inlet pipe contains debris of different degrees of blockage, acquire the capacitance value of a capacitor corresponding to each degree of blockage; determine the temperature compensation capacitance value corresponding to each capacitance value; and store the correspondence between the capacitance value, the temperature value, and the temperature compensation capacitance value.
[0072] In some embodiments, the first control module 430 is specifically configured to determine the current level of congestion corresponding to the current compensated capacitance value; determine the current reminder strategy corresponding to the current level of congestion; and process it.
[0073] In some embodiments, the first control module 430 is further configured to perform a blockage reminder when the current compensated capacitance value is greater than or equal to the blockage capacitance threshold and less than the preset capacitance upper limit, wherein the preset capacitance upper limit is greater than the blockage capacitance threshold.
[0074] In some embodiments, the system further includes a second control module configured to issue an invalid detection alert when the current compensated capacitance value is greater than or equal to a preset upper limit of capacitance, or when the current compensated capacitance value is less than or equal to a preset lower limit of capacitance; wherein the preset lower limit of capacitance is less than a blockage capacitance threshold.
[0075] The following describes in detail the DC washing machine control process using a device for controlling a DC washing machine.
[0076] In this embodiment, the DC washing machine, such as Figure 1 As shown, the device includes: an upper plate 1 and a lower plate 3 of a capacitor, and a drain pump inlet pipe 2 located between the upper plate 1 and the lower plate 3. The upper plate 1 and the lower plate 3 are parallel and can be attached to the outside of the drain pump inlet pipe 2, forming the capacitor in the DC washing machine. The control circuit of the DC washing machine is powered by DC. Furthermore, a preset capacitance threshold Ca, a preset upper capacitance limit Cmax, and a preset lower capacitance limit Cmin are defined.
[0077] Figure 5 This is a schematic diagram of a control device for a DC washing machine provided in an embodiment of this disclosure. Figure 5 As shown, the control device for a DC washing machine is powered by DC and includes: an acquisition module 410, a determination module 420, a first control module 430, a configuration storage module 440, and a second control module 450.
[0078] The configuration storage module 440 stores the correspondence between the capacitance value, temperature value and temperature compensation capacitance value.
[0079] In this way, after the acquisition module 410 acquires the current capacitance value Cn of the capacitor in the DC washing machine in real time or at regular intervals, and the current ambient temperature value, the determination module 420 can determine the current temperature compensation capacitor value that matches the current capacitance value Cn and the current ambient temperature value according to the correspondence between the capacitance value, temperature value and temperature compensation capacitor value stored in the configuration storage module 440, and obtain the current compensated capacitance value Cr.
[0080] Therefore, if the current compensated capacitance value Cr is between [Cmin, Cmax] and Cr ≥ Ca, the first control module 430 can provide one or more congestion reminders, such as text, light, or voice, and can also send congestion reminder information to the terminal. However, if the current compensated capacitance value Cr is not between [Cmin, Cmax], i.e., Cr ≤ Cmin, or Cr ≥ Cmax, the second control module 440 can reset the capacitor, detect invalidity, and provide an invalidity reminder.
[0081] As can be seen, in this embodiment, two parallel electrode plates are attached to the outside of the drain pump inlet pipe of the DC washing machine, forming a capacitor. In this way, the device for controlling the DC washing machine can obtain the current capacitance value of the DC washing machine capacitor and the current ambient temperature value, and obtain the current compensated capacitance value after temperature compensation. If the current compensated capacitance value is greater than or equal to the blockage capacitance threshold, a blockage reminder can be issued in time. This allows for timely cleaning of debris in the drain pump inlet pipe, reducing the probability of blockage and further reducing the chance of damaging the DC washing machine, thus improving the user experience.
