[0037] Exemplary embodiments of the present application will be described hereinafter with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0038] It should be noted that the technical terms or scientific terms used in the present application should be understood as their general meanings understood by the skilled in the art, unless otherwise specified.

[0039] A deodorization control method and device, a laundry treatment device, and a storage medium are described below with reference to the accompanying drawings.

[0040] Currently, electric appliances with deodorization function in the related art usually adopt two deodorization schemes. One scheme is to use steam for deodorization. This scheme usually performs deodorization processing simultaneously in the process of performing an additional processing program of the electric appliance, for example, deodorization by passing in steam in the process of performing a drying program. This scheme performs deodorization processing simultaneously with other programs, and the deodorization processing is difficult to match the real odor situation of the load, and there is a situation that all odor molecules on the load cannot be removed, or after all odor molecules are removed, the deodorization processing is still continued, resulting in a waste of resources.

[0041] Another scheme is to set an adsorbent in the electric appliance, and to adsorb odor molecules by the adsorbent. Since the adsorbent is always adsorbing before reaching saturation, the adsorbent needs to be replaced after reaching saturation. Therefore, in this scheme, there is no need to control the deodorization processing by a program, and only the adsorbent needs to be replaced regularly. However, the adsorbent is a consumable, and the cost is high. If the replacement cycle of the adsorbent is not reasonable, the deodorization effect will also be affected.

[0042] In view of the problem of poor deodorization effect in the related art, the present application provides a deodorization device, Figure 1 a structural schematic diagram of the deodorization device is shown, Figure 2 a three-dimensional sectional view of the deodorization device is shown, Figure 3 a structural exploded view of the deodorization device is shown. Among them Figure 2 is a sectional view of the deodorization device shown in Figure 1 along the direction of A-A'.

[0043] As shown in Figures 1-3 , the deodorization device includes an excitation source 1, a deodorization plate 2, and a shell 3. The deodorization plate 2 includes an adsorbent capable of adsorbing odor molecules and a catalyst capable of decomposing odor molecules; the shell 3 is provided with a plurality of through holes 31, and the deodorization plate 2 is arranged in the shell 3; at least part of the excitation source 1 is arranged in the shell 3, and is used to excite the catalyst to decompose odor molecules.

[0044] The catalyst and the adsorbent included in the odor-removing plate 2 can be the same material or different materials. In some embodiments, the catalyst and the adsorbent included in the odor-removing plate 2 can be implemented by at least one material with a composite function, which can be a material with both adsorption function and catalytic oxidation function, such as a modified MOF (Metal-Organic Framework) material, a carbon nitride material, etc.

[0045] In other embodiments, the catalyst and the adsorbent included in the odor-removing plate 2 can be implemented by different materials. Among them, the catalyst can include at least one material with catalytic oxidation function, such as an oxidation metal material, a sulfide material, a nitride material, etc. The oxidation metal material can include titanium dioxide, zinc oxide, etc., the sulfide material can include ferrous sulfide, copper sulfide, etc., and the nitride material can include titanium nitride, boron nitride, etc. The adsorbent can include at least one material with adsorption function, such as activated carbon, lignocellulose, etc. In these embodiments, the catalyst and the adsorbent can be mixed in a certain ratio to make the above-mentioned odor-removing plate 2, and the mixing ratio of the catalyst and the adsorbent can include but is not limited to 1:1, 1:2, 1:3, etc.

[0046] Some holes can be provided on the odor-removing plate 2, such as making the odor-removing plate 2 into a honeycomb structure or a mesh structure, etc., which can increase the contact area of the odor-removing plate 2 with air, thereby improving the probability of the adsorbent and the catalyst included in the odor-removing plate 2 contacting odor molecules, and improving the adsorption capacity and decomposition capacity of the odor-removing plate 2 for odor molecules.

[0047] Since the odor-removing plate 2 includes both the adsorbent with the function of adsorbing odor molecules and the catalyst with the function of decomposing odor molecules, when the odor-removing device provided in the embodiments of the present application is used for odor removal, odor molecules will be adsorbed onto the adsorbent in the odor-removing plate 2, and the catalyst on the odor-removing plate 2 will be catalytically activated to eliminate odor molecules in the environment around the catalyst. The odor molecules in the environment around the catalyst include odor molecules in the air around the catalyst and odor molecules adsorbed on the adsorbent around the catalyst.

[0048] Because the catalyst can decompose the odor molecules adsorbed on the adsorbent, thereby releasing the adsorption sites of the adsorbent, the adsorbent can be continuously used without reaching the saturation state of the adsorbent, so there is no need to replace the adsorbent, which not only improves the odor removal effect but also reduces the cost.

[0049] A plurality of through holes 31 are provided on the shell 3, air can enter the inside of the shell 3 through the through holes 31, and odor molecules in the air are adsorbed by the adsorbent included in the odor-removing plate 2 located in the shell 3 and decomposed by the catalyst included in the odor-removing plate 2, thereby removing the odor molecules in the air. The air after removing the odor molecules is discharged to the outside of the shell 3 through the through holes 31.

[0050] The multiple through holes 31 on the outer casing 3 can be evenly or unevenly arranged. Through holes 31 can be provided on one or more sides of the outer casing 3. For two opposite sides of the outer casing 3, such as a first side and a second side, each through hole 31 on the first side can have a corresponding through hole 31 on the second side. Here, "corresponding through hole 31" refers to the mapping position of the through hole 31 on the first side on the second side, which coincides with the position of the corresponding through hole 31 on the second side. This structure improves the airflow when passing through the deodorizing device, that is, it increases the amount of air passing through the deodorizing plate 2 per unit time, thereby improving the deodorizing efficiency.

[0051] At least a portion of the excitation source 1 is disposed within the housing 3 to facilitate the activation of the catalyst contained in the deodorizing plate 2 located within the housing 3.

[0052] In some embodiments of this application, such as Figure 4 The schematic diagram of the excitation source 1 shown includes a first positive electrode 11, a first negative electrode 12, and a light source 13. The light source 13 is connected to the first positive electrode 11 and the first negative electrode 12. The light source 13 is disposed inside the housing 3, and the first positive electrode 11 and the first negative electrode 12 are disposed outside the housing 3. The first positive electrode 11 and the first negative electrode 12 are used to connect to an external power supply. The light source 13 includes any one of a full-spectrum light source, an ultraviolet light source, and an infrared light source.

[0053] Figure 3 Excitation source 1 in the diagram is schematically shown as an excitation source including light source 13. Excitation source 1 employs... Figure 4 In the case of the structure shown, the deodorizing plate 2 can be designed as a sleeve-like structure with a hollow channel. The channel is surrounded by the plate material of the deodorizing plate 2, and the light source 13 of the excitation source 1 is inserted into the hollow channel. This structure can be referenced. Figure 3 The exploded view of the deodorization device shown shows that the structure is designed so that when the light source 13 is lit, it can fully illuminate the deodorization plate 2, thereby improving the activation efficiency of the catalyst in the deodorization plate 2.

[0054] After the first positive electrode 11 and the first negative electrode 12 are connected to an external power source, the light source 13 is illuminated. The light shines on the deodorizing plate 2, causing the catalyst contained in the deodorizing plate 2 to undergo electronic transitions, thereby enabling it to undergo an oxidation-reduction reaction with odor molecules. In addition, while the excitation source 1 uses the light source 13 to excite the catalyst, the light also shines on the surrounding air or the loading object that needs to be deodorized. The light shining on the air increases the activity of molecules in the air, which helps to improve the adsorption and decomposition efficiency of odor molecules in the air by the deodorizing plate 2. When the light shines on the loading object, it can generate a photothermal effect through light radiation, sterilizing and protecting the loading object. At the same time, it stimulates the resonance of odor molecules, accelerating the detachment of odor molecules from the loading object into the air, thereby improving the deodorization efficiency and effect on the loading object.

[0055] When the light source 13 adopts a full-spectrum light source, the spectral range is richer, which can excite the vibration of chemical bonds in odor molecules, causing the odor molecules attached to the load to resonate, prompting the odor molecules to accelerate their detachment from the load and enter the air. Therefore, the full-spectrum light source is more conducive to improving the deodorization effect.

[0056] In other embodiments of this application, such as Figure 5 The schematic diagram of the excitation source 1 shown includes a second positive electrode 14, a second negative electrode 15, a positive terminal 16, and a negative terminal 17. The second positive electrode 14 and the second negative electrode 15 are disposed outside the housing 3 for connection to an external power source. The positive terminal 16 and the negative terminal 17 are disposed inside the housing 3 and connected to the deodorizing plate 2. The second positive electrode 14 is connected to the positive terminal 16, and the second negative electrode 15 is connected to the negative terminal 17.

[0057] The connection between the positive terminal 16 and the negative terminal 17 and the deodorizing plate 2 can be welded or detachable. After the second positive electrode 14 and the second negative electrode 15 are connected to an external power source, current is applied to the deodorizing plate 2 through the positive terminal 16 and the negative terminal 17, thereby electrocatalyzing the catalyst in the deodorizing plate 2. Under the action of electrical energy, the catalyst undergoes electron transition, thus enabling it to undergo an oxidation-reduction reaction with odor molecules.

[0058] The deodorizing device provided in this application combines the characteristics of adsorption and catalytic oxidation of odor molecules. During the deodorizing process using this device, odor molecules in the air surrounding the deodorizing plate are captured by the adsorbent and placed on the adsorption sites on its surface. At the same time, the catalyst, under the action of the excitation source, oxidizes and decomposes the odor molecules in the surrounding air and the odor molecules adsorbed on the surface of the adsorbent, thereby removing the odor molecules.

[0059] The adsorbent has a highly efficient ability to capture odor molecules, thus quickly removing odors from the air and concentrating dispersed odor molecules in the area surrounding the catalyst. While odor molecules are adsorbed, the catalyst decomposes odor molecules in the surrounding area, including those in the surrounding air and those adsorbed on the adsorbent surface. This improves deodorization efficiency and releases adsorption sites on the adsorbent surface occupied by odor molecules, allowing the adsorbent to be used for a long time without replacement.

[0060] Other embodiments of this application also provide an electrical device, which includes an air duct and a deodorizing device provided in any of the above embodiments; the deodorizing device is disposed within the air duct.

[0061] The aforementioned electrical appliances can be any device with an air duct or fresh air system, such as washing machines, dryers, washer-dryer combos, tumble dryers, dishwashers, air purifiers, air conditioners, or refrigerators. The deodorizing device can be installed anywhere within the air duct of the electrical appliance, such as behind the filter assembly. This means the airflow reaches the deodorizing device after passing through the filter assembly, allowing the filter to remove airborne debris such as lint and dander, reducing the likelihood of clogging the openings on the deodorizing device's casing.

[0062] The air duct inside the electrical equipment can be used to form a circulating air path. When the airflow passes through the deodorizing device, it enters through the through holes on the outer shell of the deodorizing device. The odor molecules carried in the air are adsorbed by the adsorbent in the deodorizing plate and oxidized and reduced by the catalyst in the deodorizing plate, thereby removing the odor molecules carried in the air. Then, the fresh air is discharged from the through holes in the outer shell, which achieves the removal of odor molecules inside the electrical equipment. Moreover, the adsorbent in the deodorizing plate can be recycled under the action of the catalyst, so there is no need to replace the adsorbent. It has a good deodorizing effect and reduces costs.

[0063] Some embodiments of this application provide a method for odor control; see [link to relevant documentation]. Figure 6 The method includes the following steps 101-103.

[0064] Step 101: Obtain the odor index of the loading material, which is used to characterize the difficulty of decomposing the odor on the loading material.

[0065] Step 102: Determine the program parameters of the odor removal program based on the odor index.

[0066] Step 103: Perform a deodorization procedure on the load based on the program parameters.

[0067] The executing entity in this application embodiment can be an electrical device used to perform an odor removal control method. In this embodiment, the electrical device acquires the odor index of the load. The odor index can characterize the difficulty of decomposing the odor on the load, so the odor index can reflect the actual situation of odor contamination on the load. Based on the odor index of the load, the program parameters of the odor removal program are determined. The program parameters determined in this way have a high degree of matching with the odor situation on the load. By executing the odor removal program on the load according to the determined program parameters, the odor removal effect on the load can be greatly improved.

[0068] The load can be the object processed by the electrical appliance. For example, if the appliance is a clothes dryer, the load can be clothes; if the appliance is a dishwasher, the load can be dishes.

[0069] Odor indices are parameters that quantify the odors adhering to a substrate, reflecting the difficulty of decomposing the odors. Odor indices include, but are not limited to, one or more of odor level, odor type, and odor concentration. Odor level may include, but is not limited to, mild, moderate, and severe. Odor type may include, but is not limited to, sweat odor, formaldehyde odor, smoke odor, alcohol odor, hot pot odor, and cooking fumes.

[0070] In some embodiments of this application, the electrical equipment may be equipped with an interactive component for users to submit odor indicators of the load. Users can submit their configured foreign matter indicators to the electrical equipment through this interactive component. The electrical equipment receives the odor indicators of the load submitted by the user.

[0071] The aforementioned interactive components may include, but are not limited to, buttons, touchscreens, etc. In embodiments where the foreign object indicator is submitted by the user, the foreign object indicator may include odor level and / or odor type.

[0072] Odor type is relatively easy for users to identify. However, regarding odor level, in some embodiments, users can determine the odor level based on their subjective perception of the intensity of the odor emitted by the load. For example, the electrical device provides physical buttons corresponding to different odor levels. Suppose there are three physical buttons: "mild," "moderate," and "severe." If a user clicks the "severe" button based on the intensity of the odor emitted by the load, the electrical device will detect that the "severe" button has been clicked and determine that the odor index of the load is "severe."

[0073] In other embodiments, the differences in decomposition difficulty among different odor types can be experimentally determined in advance. Specifically, the same deodorization device can be used to process the same load material with the same concentration but different odor types, and the processing time required for different odor types can be measured. Based on the processing time required for different odor types, the decomposition difficulty of different odor types is qualitatively analyzed; the longer the processing time, the greater the decomposition difficulty. Based on the differences in decomposition difficulty, the odor level corresponding to different odor types is determined. Specifically, from the processing times corresponding to different odor types, the minimum and maximum processing times can be determined. According to the number of odor levels to be divided, the interval formed by the minimum and maximum processing times is divided into equal sub-intervals of that level. According to the order of odor levels from low to high and the order of duration of each sub-interval from short to long, each odor level is mapped one-to-one with each sub-interval. The sub-interval to which the processing time corresponding to an odor type belongs is determined, and the odor level corresponding to that sub-interval is determined.

[0074] For example, suppose the processing time for sweat odor is 5 minutes, formaldehyde odor is 6 minutes, smoke odor is 15 minutes, alcohol odor is 18 minutes, hot pot odor is 23 minutes, and cooking odor is 25 minutes, as tested in the above manner. Assume the odor levels are divided into three categories: mild, moderate, and severe. Then, the interval [5,25] is divided into three sub-intervals: [5,12), [12,19), and [19,25]. The odor level "mild" corresponds to sub-interval [5,12), the odor level "moderate" corresponds to sub-interval [12,19), and the odor level "severe" corresponds to sub-interval [19,25]. The processing times for both odor types "sweat odor" and "formaldehyde odor" fall within sub-interval [5,12), therefore, the odor types "sweat odor" and "formaldehyde odor" correspond to the odor level "mild." The processing times for the odor types "smoke" and "alcohol" both fall within the sub-interval [12,19), therefore, the odor types "smoke" and "alcohol" correspond to the odor level "moderate". The processing times for the odor types "hot pot smell" and "cooking smoke smell" both fall within the sub-interval [19,25], therefore, the odor types "hot pot smell" and "cooking smoke smell" correspond to the odor level "severe".

[0075] The processing times for each odor type in the above examples are only used to illustrate how to determine the correspondence between odor level and odor type, and are not intended to illustrate the actual processing time for each odor type.

[0076] After determining the odor level corresponding to each odor type using the above method, the correspondence between different odor types and odor levels is provided to the user through the aforementioned interactive components. For example, the correspondence between each odor type and odor level can be displayed on a touchscreen, allowing the user to select the corresponding odor level based on the odor type on the load. Alternatively, physical buttons corresponding to different odor levels can be set on the control panel of the electrical appliance, with each physical button labeled with its corresponding odor level and odor type, making it convenient for the user to select the appropriate physical button based on the odor type on the load.

[0077] In addition to users submitting odor indicators locally on the electrical appliance, in some other embodiments of this application, users can also submit odor indicators via a client on a user terminal such as a mobile phone or tablet. This client can be the client corresponding to the electrical appliance, i.e., a client for users to manage and use the electrical appliance. The client can display an interface for users to submit odor indicators, which may include buttons corresponding to odor levels and / or odor types. Users can submit odor indicators to the client by clicking the corresponding buttons. After detecting that a button has been clicked, the client determines the odor level and / or odor type corresponding to the clicked button and sends the determined odor level and / or odor type to the electrical appliance, which then receives the odor indicator.

[0078] In one implementation, the client terminal and the appliance are connected via Wi-Fi, Bluetooth, or other communication methods. The client directly sends the odor indicators submitted by the user to the appliance. In another implementation, both the appliance and the client terminal are connected to the server. The client first sends the odor indicators submitted by the user to the server. The server then forwards the odor indicators to the appliance belonging to the user of that client.

[0079] In the above-mentioned various embodiments where odor indicators are submitted by users, the interaction with users is strong, which increases user participation and helps to increase the frequency of use of the odor removal program.

[0080] In other embodiments of this application, a detection device may also be installed on the electrical equipment to automatically detect the odor index of the load. In these embodiments, the odor index may include one or more of odor level, odor concentration, and odor type.

[0081] The detection device may include, but is not limited to, odor sensors, concentration sensors, etc. The detection device can be installed in a container within electrical equipment to hold the load, or it can be installed within the air duct of the electrical equipment.

[0082] In some embodiments, the electrical equipment can detect the odor type of the load using a detection device, and use the odor type as an odor index of the load. Further, after detecting the odor type, the odor level of the load can be determined based on a preset correspondence between odor types and odor levels, and the odor level can be used as an odor index, or both the odor type and odor level of the load can be used as an odor index of the load. The preset correspondence between odor types and odor levels can be obtained in the manner described above.

[0083] In other embodiments, the electrical equipment can also detect the odor concentration of the load using a detection device, and use the odor concentration as an odor index of the load. Alternatively, the electrical equipment can detect the odor type and odor concentration of the load using a detection device, and use the odor type and corresponding odor concentration as an odor index of the load. Furthermore, based on the detected odor type, a corresponding odor level can be determined, and the odor level and odor concentration can be used as odor indices, or the odor type, odor level, and odor concentration can be used as odor indices.

[0084] Electrical equipment automatically detects odor indicators of the load through a detection device, which improves the automation level of the equipment. The deodorization process does not require user intervention, and the automatically detected odor indicators are more accurate and more consistent with the actual situation of the load carrying odors. Subsequent processing based on the automatically detected odor indicators can effectively improve the deodorization effect on the load.

[0085] After obtaining the odor index of the load, the electrical equipment can determine the corresponding program parameters of the odor index of the load from the preset mapping relationship between odor index and program parameters; the determined program parameters are used as the program parameters of the deodorization program to be performed on the load.

[0086] The deodorization program parameters include the program's runtime, fan speed, and excitation source power. The excitation source is used to activate the catalyst that can decompose odor molecules.

[0087] In the embodiments of this application, the value range of each program parameter corresponding to different odor indicators can be determined in advance through a large number of experiments. The program parameters within the value range are used to deodorize the loading material of the corresponding odor indicator, which can achieve a good deodorization effect.

[0088] Assuming the correspondence between the measured different odor indicators and the value ranges of the program parameters is shown in Table 1, in some embodiments, the excitation source may include a light source. Alternatively, in other embodiments, the excitation source may be an excitation power source. Table 1 shows the power of the light source and the power of the excitation power source corresponding to different odor indicators.

[0089] Table 1

[0090]

[0091] A value can be selected from the range of program parameters corresponding to the measured odor index. The mapping relationship between different odor indices and the selected program parameter values ​​can be pre-configured in the electrical equipment. The configured mapping relationship is the above-mentioned preset mapping relationship between odor index and program parameter.

[0092] For electrical equipment including fans and deodorizing devices including excitation sources, the above embodiments can be used to automatically determine the parameters of the deodorization process based on the odor index of the load.

[0093] By pre-setting the mapping relationship between odor indicators and program parameters in electrical appliances, the appliances can automatically determine program parameters based on the odor indicators of the load. The determined program parameters have a higher compatibility with the actual odor situation of the load, and subsequent use of these program parameters to execute the deodorization program can achieve better deodorization results.

[0094] In some embodiments of this application, the electrical equipment may also include a heating device, which may be located inside or outside the container used to hold the load, or within the air duct of the electrical equipment. The program parameters of the deodorization program may further include a heating flag indicating whether the heating device is activated and the heating power of the heating device. Determining the program parameters of the deodorization program based on odor indicators further includes:

[0095] From the preset mapping relationship between odor indicators and heating flags, obtain the heating flag corresponding to the odor indicator of the load; according to the obtained heating flag, turn on the heating device, and from the preset mapping relationship between odor indicators and heating power, obtain the heating power corresponding to the odor indicator of the load.

[0096] The heating flag can be preset with characters to indicate whether the heating device is on or off, such as "yes" or "1" for on and "no" or "0" for off. The preset mapping relationship between odor indicators, heating flag, and heating power can be as shown in Table 2.

[0097] Table 2

[0098] Odor type Odor level Heating flag Heating power (W) Sweat, formaldehyde Mild No / Smoke, wine Moderate Yes 700-1100 Hot pot, oil smoke Heavy Yes 1100-1800

[0099] In cases where electrical equipment includes a heating device, the above embodiments can be used to determine whether to activate the heating device based on odor indicators, and if activation is determined, to further determine the heating power of the heating device. Thus, when electrical equipment has a heating device, the activation of the heating device and its heating power can be automatically determined based on the odor indicators of the load, resulting in a higher degree of automation in the deodorization process. Furthermore, activating the heating device raises the temperature of the environment surrounding the load, thereby increasing the activity of odor molecules on the load and allowing them to detach from the load and enter the air more quickly, thus accelerating the deodorization rate.

[0100] After the electrical equipment automatically determines the program parameters of the deodorization program based on the odor index of the load, it executes the deodorization program on the load. Specifically, based on the fan speed included in the program parameters, it controls the operation of the fan; based on the power of the excitation source included in the program parameters, it controls the operation of the excitation source; and when the running time of the fan and the excitation source reaches the running time included in the program parameters, it controls the fan and the excitation source to stop running.

[0101] The operation of the fan creates a circulating airflow within the electrical equipment's ductwork. This airflow carries odor molecules from the load and blows them to the deodorizing device, where they enter through openings in the device's casing. If the device includes an adsorbent, the odor molecules are adsorbed onto adsorption sites on its surface. If the device's excitation source includes a light source, the light is illuminated according to the odor index, illuminating the catalyst within the device. This photocatalysis decomposes odor molecules from the surrounding air and the adsorbent surface, thus removing them. Furthermore, the light illuminating the load has a bactericidal effect and causes the chemical bonds of the odor molecules attached to the load to resonate, accelerating the detachment of odor molecules and increasing the deodorization rate.

[0102] If the excitation source in the deodorization device is an excitation power supply, the excitation power supply is turned on according to the power of the excitation voltage determined by the odor index, and current is applied to the deodorization plate in the deodorization device. Under the action of electrocatalysis, the catalyst in the deodorization plate decomposes the odor molecules in the surrounding air and on the surface of the adsorbent, thereby removing the odor molecules.

[0103] Perform the above-described operation for the specified duration, then shut down the fan and excitation source. Since the program parameters are determined based on the odor index of the load, they are more closely matched to the actual odor situation of the load. Controlling the fan operation based on this predetermined speed and controlling the excitation source operation based on this predetermined power allows for better removal of odors from the load, achieving excellent deodorization without wasting resources. Furthermore, the deodorization device utilizes an adsorbent and a catalyst. The catalyst continuously decomposes odor molecules on the surface of the adsorbent, releasing adsorption sites, allowing the adsorbent to be recycled without replacement, thus reducing costs.

[0104] When the electrical equipment includes a heating device, and the program parameters determined based on the odor index include program parameters related to the heating device, the heating device is turned on based on the heating flag bit indicated in the program parameters, and the heating device is controlled to start operation with the heating power included in the program parameters; when the operating time of the heating device reaches the operating time included in the program parameters, the heating device is controlled to stop operation.

[0105] Since the program parameters are determined based on the odor index of the load, whether the heating device needs to be turned on, and if so, at what power, can be matched with the actual odor situation of the load. Based on this determined heating flag, it is determined whether to turn on the heating device. When turned on, the heating device is controlled to operate according to the heating power determined by the odor index, raising the temperature of the environment where the load is located. This increases the activity of odor molecules on the load, allowing them to detach from the load and enter the air more quickly, thereby accelerating the deodorization rate.

[0106] In some embodiments of this application, the control panel of the electrical appliance may provide a button for activating the deodorization program. The electrical appliance determines that the deodorization program needs to be executed when it detects that the button has been clicked by a user. Alternatively, the electrical appliance determines that the deodorization program needs to be executed when it receives an odor indicator submitted by a user. Or, the electrical appliance determines that the deodorization program needs to be executed when it automatically detects an odor indicator of the load through a detection device.

[0107] If the electrical equipment does not detect the user-triggered command to start the deodorization program, nor does it receive any odor indicators submitted by the user, and the detection device does not detect any odor indicators on the load, then the deodorization program will not be executed on the load. Instead, a non-deodorization program specified by the user will be executed. The non-deodorization program may include, but is not limited to, drying programs, washing programs, and sterilization programs.

[0108] In some embodiments of this application, if the electrical device receives a non-odor removal program execution command, it increments the cumulative execution count of the non-odor removal program by 1; if it receives an odor removal program execution command, it resets the cumulative execution count to zero. Each time the cumulative execution count is incremented, the electrical device compares the cumulative execution count with a preset threshold. If the cumulative execution count is greater than or equal to the preset threshold, a preset regeneration program is executed. This preset regeneration program is used to decompose the odor molecules adsorbed on the adsorbent. If the cumulative execution count is less than the preset threshold, the device continues to detect whether the received program execution command is a non-odor removal program execution command, and repeats this process until the cumulative execution count is greater than or equal to the preset threshold.

[0109] The aforementioned preset threshold can be, but is not limited to, 8, 10, or 15. Since the excitation source in the deodorization device is not activated to activate the catalyst during the non-deodorization process of the electrical equipment, odor molecules inevitably exist within the equipment. These odor molecules may be adsorbed by the adsorbent in the deodorization device, occupying adsorption sites on the adsorbent surface. Because the catalyst is not activated, the odor molecules at some adsorption sites cannot be decomposed in time, and the adsorption sites cannot be released promptly. As the number of consecutive non-deodorization processes increases, the adsorbent may gradually reach saturation, affecting the efficiency of subsequent deodorization processes. Therefore, in the above embodiment, upon detecting that the number of consecutive non-deodorization processes has reached the preset threshold, a preset regeneration process is executed to decompose the odor molecules adsorbed on the adsorbent, releasing the occupied adsorption sites on the adsorbent surface and preparing for subsequent deodorization processes.

[0110] The aforementioned preset regeneration program can be a program pre-configured in the electrical equipment. This preset regeneration program can pre-configure the power of the excitation source and the runtime of the preset regeneration program. In this embodiment, the runtime is referred to as the preset regeneration duration. The preset regeneration duration can be 5 minutes, 10 minutes, or 15 minutes, etc.

[0111] The electrical equipment determines that the cumulative number of operations is greater than or equal to a preset threshold, and controls the operation of the excitation source, which is used to activate the catalyst that can decompose odor molecules; when the operation time of the excitation source reaches the preset regeneration time of the adsorbent, the excitation source is controlled to stop operating.

[0112] The electrical equipment can control the operation of the excitation source based on the power of the excitation source pre-configured in the preset regeneration program. By executing the preset regeneration program, the odor molecules accumulated on the adsorbent are decomposed, releasing the adsorption sites of the adsorbent. In this way, if the next program executed by the electrical equipment is a deodorization program, the adsorbent will have enough adsorption sites available, improving the processing efficiency of the deodorization program.

[0113] In some embodiments of this application, when the electrical device receives the execution instruction of the non-deodorization program, it increments the cumulative number of runs by 1. That is, the non-deodorization program has just started to be executed. If it is determined that the cumulative number of runs is greater than or equal to a preset threshold, in some embodiments, a preset regeneration program can be executed during the operation of the currently running non-deodorization program.

[0114] During the execution of the non-odor removal program, the preset regeneration program is executed, so that the preset regeneration time of the preset regeneration program is included in the runtime of the non-odor removal program. This makes the execution of the preset regeneration program imperceptible to the user and prevents the user from waiting due to the separate execution of the preset regeneration program.

[0115] In other embodiments, the electrical device determines that the cumulative number of runs is greater than or equal to a preset threshold, and the currently running non-deodorization program has ended. It then detects that the load has been removed and executes a preset regeneration program. In other words, the preset regeneration program is executed only after the non-deodorization program has ended and the load in the electrical device has been removed by the user, thus ensuring that the user can use the load without interruption.

[0116] The odor control method provided in this application is applicable to the odor control devices provided in any of the preceding embodiments, i.e., odor control devices including odor control plates containing adsorbents and catalysts and excitation sources. It is also applicable to odor control devices that include catalysts and excitation sources but do not include adsorbents.

[0117] To facilitate understanding of the complete process of the odor control method provided in the embodiments of this application, the following is in conjunction with the appendix. Figure 7 Let's illustrate with examples.

[0118] S1: The electrical equipment receives the program execution instruction.

[0119] S2: Determine whether the program execution instruction is the execution instruction of the deodorization program. If yes, execute step S3; otherwise, execute step S7.

[0120] S3: Reset the cumulative number of runs of the non-odor removal program to zero, and obtain the odor index of the load, and determine the program parameters of the odor removal program based on the odor index.

[0121] If the odor index is "mild", proceed to step S4; if the odor index is "moderate", proceed to step S5; if the odor index is "severe", proceed to step S6.

[0122] S4: Based on the program parameters, control the fan to run at 800r / min and control the full-spectrum light source to run at 1.5W power. After running for 10 minutes, turn off the fan and the light source.

[0123] S5: Based on program parameters, control the fan to run at 1500r / min and control the full-spectrum light source to run at 3W power. After running for 15 minutes, turn off the fan and the light source.

[0124] S6: Based on program parameters, control the fan to run at 2000r / min and control the full-spectrum light source to run at 5W power. After running for 20 minutes, turn off the fan and the light source.

[0125] S7: Increment the cumulative number of runs of the non-odor removal program by 1, and determine whether the cumulative number of runs is greater than or equal to the preset threshold. If yes, proceed to step S8; otherwise, return to step S1.

[0126] S8: Execute the preset regeneration program, specifically turn on the excitation source, turn off the excitation source when the preset regeneration time is reached, and then return to step S1.

[0127] The parameter values ​​in steps S4-S6 above are all illustrative.

[0128] Taking a clothes dryer as an example, with clothes as the load, and a light source as the excitation source for the deodorizing device in the dryer, such as... Figure 8 The diagram illustrating the odor removal principle shows that when the dryer is running, the excitation light source shines on the user's clothes. This light radiation generates a photothermal effect, sterilizing and caring for the clothes. Simultaneously, it stimulates the resonance of odor molecules, causing them to detach from the clothes and enter the internal air circulation duct. In the duct, the odor molecules are captured by a widely acting adsorbent at their surface adsorption sites. Meanwhile, a catalyst, under the influence of the light source, oxidizes and decomposes the surrounding odor molecules (including those in the air and on the adsorbent surface), completely removing the odors.

[0129] The adsorbent has a highly efficient ability to capture odor molecules, thus quickly removing odors during the operation of the dryer and concentrating dispersed odor molecules in the area surrounding the catalyst. While odor molecules are adsorbed, the catalyst decomposes odor molecules in the surrounding area, including those in the surrounding air and those adsorbed on the adsorbent surface, improving overall odor removal efficiency. Simultaneously, it releases adsorption sites on the adsorbent surface occupied by odor molecules, allowing the adsorbent to be used for a long time without replacement.

[0130] This application also included an odor removal test. A dryer using both an adsorbent and a catalyst, and a dryer using only a catalyst, were used to deodorize clothes with the same type of odor for the same duration. The test showed that the dryer using both an adsorbent and a catalyst had significantly improved odor removal efficiency. After the deodorization process was completed, the odor level of the clothes in the dryer using both an adsorbent and a catalyst was significantly lower than that in the dryer using only a catalyst. The test results are shown in Table 3.

[0131] Table 3

[0132]

[0133] The same dryer was set to specific temperature and humidity conditions. Ammonia was added to the enclosed space of the dryer to simulate odor. Deodorization was performed using a catalyst at two different time periods, and also using an adsorbent and a catalyst. In both tests, the gas path was circulated for 10 minutes. The test using only the catalyst reduced the odor concentration by 57.4%, while the test using both the adsorbent and the catalyst reduced the odor concentration by 86.6%, demonstrating a significant improvement in deodorization effect.

[0134] In this embodiment, the electrical device can acquire the odor index of the load. The odor index characterizes the difficulty of decomposing the odor on the load, thus reflecting the actual situation of odor contamination on the load. Based on the odor index of the load, the program parameters of the deodorization program are automatically determined. The program parameters have a high degree of matching with the odor condition of the load. Executing the deodorization program on the load according to the program parameters can significantly improve the deodorization effect. Furthermore, the deodorization device used in this embodiment can simultaneously use an adsorbent and a catalyst. The adsorbent can concentrate odor molecules near the deodorization device and adsorb them onto the adsorbent surface. After catalytic activation, the catalyst can decompose odor molecules in the surrounding air and on the adsorbent surface, thereby achieving the effect of odor removal. Moreover, the catalyst decomposes odor molecules on the adsorbent surface, continuously releasing adsorption sites on the adsorbent, allowing the adsorbent to be recycled without replacement, resulting in low cost and good deodorization effect.
