In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0021] See also Figures 1 to 4 , Figure 1 is an exploded view of a plasma module provided by one embodiment of the present invention; Figure 2 is a schematic diagram of the layout of multiple plasma modules provided by one embodiment of the present invention; Figure 3 is a schematic structural diagram of a dielectric component provided by an embodiment of the present invention; Figure 4 FIG. 1 is a schematic diagram of an inner loop provided by an embodiment of the present invention. Figure 1As shown, the plasma module includes a dielectric component and a discharge component; the dielectric component is used to form a discharge area; the discharge component is arranged on both sides of the dielectric component to generate plasma; wherein, when the discharge component discharges, the plasma fills the discharge area.

[0022] Specifically, cleaning equipment is usually used to clean utensils. Different cleaning equipment can clean different types of utensils. For example, the cleaning equipment can be a dishwasher, which can be used to clean tableware. Generally, after the dishwasher finishes cleaning the tableware, the user needs to take the tableware out of the dishwasher and place it in a cupboard for storage. However, since the cupboard itself needs to be provided with a corresponding structure for storage when cleaning, the user is likely to leave the tableware in the dishwasher after the dishwasher finishes cleaning. When the tableware is left in the dishwasher for a long time, it is easy to breed bacteria and produce odor.

[0023] The cleaning equipment provided by the present invention is provided with an internal circulation device, which includes a fan assembly and a plurality of plasma modules. The internal circulation device is used to sterilize the air in the cleaning equipment to improve the cleanliness of the cleaning equipment and prevent the utensils in the cleaning equipment from generating odor. The internal circulation device may also include an air duct structure, which is used to limit the direction of movement of the airflow to facilitate the circulation of the airflow. At the same time, a fan assembly and a plurality of plasma modules are provided in the air duct structure. The specific structure of the air duct structure depends on different cleaning equipment, and its specific structure is not limited here. Figure 2 As shown, multiple plasma modules can be arranged on a fixed panel, and the fixed panel is arranged in the air duct structure. When the airflow circulates in the air duct structure, it needs to pass through the fixed panel, so that the plasma modules on the fixed panel can sterilize it. In addition, if the internal space of the cleaning equipment is small and the internal circulation structure cannot be set, the internal circulation structure can be changed to an external circulation structure, and the air in the cleaning equipment is led out from one side, and after being sterilized by the plasma module, it flows into the cleaning equipment from the other side.

[0024] The plasma module may include a dielectric component and a discharge component. The discharge component is used to excite plasma, and may include a first connection end and a second connection end. The first connection end is used to connect to a negative electrode or a grounding end, and the second connection end is used to connect to a positive electrode. The dielectric component is mainly used to provide a discharge medium to form a discharge area. The plasma excited by the discharge component can diffuse to the entire discharge area under the action of the discharge medium. When setting, the dielectric component is set in the middle of the discharge component, that is, the part of the discharge component with the first connection end is set on one side of the dielectric component, and the part of the discharge component with the second connection end is set on the other side of the dielectric component.

[0025] In actual use, take a dishwasher as an example. When the user puts the dishes into the dishwasher and starts the dishwasher, the dishwasher washes the dishes according to the set program. After the washing is completed, the dishwasher will first detect whether the door is closed. If the door is closed, it will enter the sterilization stage. In the sterilization stage, the air humidity inside the dishwasher is first detected, and the corresponding working mode is confirmed according to the air humidity. For example, when the air humidity is high, the sterilization intensity increases accordingly. When the air humidity is low, the sterilization intensity decreases accordingly. The sterilization intensity can be challenged by parameters such as the sterilization time and the wind speed of the fan component. The higher the sterilization intensity, the longer the sterilization time and the faster the fan speed. The weaker the sterilization intensity, the shorter the sterilization time and the slower the fan speed. After confirming the working mode, select the corresponding working mode, and then start the fan component and plasma module according to the selected working mode. The fan component blows the air in the dishwasher to the plasma module. When the airflow passes through the discharge area, the plasma will sterilize the passing airflow, and the airflow passing through the discharge area will circulate through the discharge area under the restriction of the air duct structure, such as Figure 4 As shown, the airflow can be continuously sterilized to improve the cleanliness of the air in the dishwasher.

[0026] As a further embodiment, the discharge assembly includes a first conductive member and a second conductive member; the first conductive member is arranged on one side of the dielectric assembly, and the second conductive member is arranged on the other side of the dielectric assembly relative to the first conductive member. As a further embodiment, one end of the first conductive member is connected to the ground electrode, and one end of the second conductive member is connected to the high voltage electrode. As a further embodiment, the first conductive member and the second conductive member are both metal meshes.

[0027] The discharge assembly may include a first conductive member and a second conductive member, both of which can conduct electricity and can be made of any conductive material, for example, both of which can be metal members. Preferably, both of the first conductive member and the second conductive member can be metal meshes, which are made of metal materials to facilitate airflow.

[0028] One of the first conductive member and the second conductive member is used to be connected to the ground terminal, and the other one is used to be connected to the high voltage pole. For example, one end of the first conductive member is connected to the ground terminal, and one end of the second conductive member is connected to the high voltage pole. When the plasma module is started, plasma is generated by the first conductive member and the second conductive member.

[0029] The first conductive member is disposed on one side of the dielectric component, and the second conductive member is disposed on the other side of the dielectric component, that is, the dielectric component is disposed between the first conductive member and the second conductive member. When the first conductive member and the second conductive member excite plasma, the plasma can diffuse to the discharge region in the dielectric component.

[0030] As a further embodiment, the dielectric component comprises a dielectric member, and the discharge components are arranged on both sides of the dielectric member. As a further embodiment, a plurality of through holes are arranged at intervals on the dielectric member.

[0031] The dielectric component may include a dielectric member, which may be composed of small-sized inorganic molecular materials, and has a plurality of through holes formed on the dielectric member. The through holes formed on the dielectric member are laid on the entire dielectric member, such as Figure 3 As shown, n through holes can be provided in the lateral direction of the dielectric member, and m through holes can be provided in the longitudinal direction of the dielectric member, and n and m are both positive integers, so a total of n*m through holes are provided on the dielectric member, and the provided through holes are used for airflow to pass through.

[0032] As a further embodiment, it further comprises a skeleton assembly, and the skeleton assembly is respectively arranged on the outer side of the first conductive member and the outer side of the second conductive member. As a further embodiment, the skeleton assembly comprises a first skeleton interception net and a second skeleton interception net, and the first skeleton interception net is arranged on the outer side of the first conductive member, and the second skeleton interception net is arranged on the outer side of the second conductive member.

[0033] The skeleton assembly is used to support the entire plasma module, and the skeleton assembly may include a first skeleton interception net and a second skeleton interception net, which are respectively arranged on both sides of the discharge assembly, for example, the first skeleton interception net is arranged on the outside of the first conductive member, and the second skeleton interception net is arranged on the outside of the second conductive member. Figure 1 As shown, the first skeleton interception net is located on the left side of the first conductive member, and the second skeleton interception net is located on the right side of the second conductive member. When assembling the plasma module, the first conductive member is placed on the first skeleton interception net, the dielectric member is placed on the first conductive member, the second conductive member is placed on the dielectric member, and finally the second skeleton interception net is placed on the second conductive member.

When the tableware is left in the dishwasher for a long time, it is easy to breed bacteria and produce odor.

[0036] The cleaning equipment provided by the present invention is provided with an internal circulation device, which includes a fan assembly and a plurality of plasma modules. The internal circulation device is used to sterilize the air in the cleaning equipment to improve the cleanliness of the cleaning equipment and prevent the utensils in the cleaning equipment from generating odor. The internal circulation device may also include an air duct structure, which is used to limit the direction of movement of the airflow to facilitate the circulation of the airflow. At the same time, a fan assembly and a plurality of plasma modules are provided in the air duct structure.

[0037] The plasma module may include a dielectric component and a discharge component.

The first connection end is used to connect to a negative electrode or a grounding end, and the second connection end is used to connect to a positive electrode.

[0039] See also Figure 5 The present invention also provides a control method, which is applied to a cleaning device and is used to control the start and stop of an internal circulation device of the cleaning device so as to clean the air in the cleaning device. The control method includes S110-S120.

[0040] S110: If it is detected that the cleaning device completes the cleaning task, the air humidity in the cleaning device is obtained.

[0041] In an embodiment of the present invention, the air humidity can be obtained by a humidity sensor, that is, a humidity sensor can be provided in the cleaning device to detect the air humidity in the cleaning device. When the cleaning device completes the cleaning task, the air humidity is obtained from the humidity sensor. Taking a dishwasher as an example, when a user puts tableware into the dishwasher and starts the dishwasher, the dishwasher washes the tableware according to the set program. After the washing is completed, the dishwasher will first detect whether the door is closed. If the door is closed, it will enter the sterilization stage. In the sterilization stage, the air humidity inside the dishwasher is first detected, and the corresponding working mode is confirmed according to the air humidity. For example, when the air humidity is high, the sterilization intensity increases accordingly, and when the air humidity is low, the sterilization intensity decreases accordingly. The sterilization intensity can be adjusted by parameters such as the sterilization time and the wind speed of the fan component. The higher the sterilization intensity, the longer the sterilization time and the faster the wind speed of the fan. The weaker the sterilization intensity, the shorter the sterilization time and the slower the wind speed of the fan. Preferably, a humidity threshold can be set, and two working modes can be set based on the humidity threshold. When the air humidity is greater than the humidity threshold, it is a strong working mode, and when the air humidity is less than or equal to the humidity threshold, it is a normal working mode. In the strong working mode, the sterilization time is longer, and in the normal working mode, the sterilization time is shorter.

[0042] For example, the humidity threshold can be 70%. When the air humidity is greater than 70%, the strong working mode is started. In the strong working mode, the sterilization time is 15 minutes per hour. When the air humidity is less than or equal to 70%, the normal working mode is started. In the normal working mode, the sterilization time is 10 minutes per hour.

[0043] S120, starting the internal circulation device, and confirming the working mode of the internal circulation device according to the air humidity so that the internal circulation device cleans the air in the cleaning equipment.

[0044] In the embodiment of the present invention, after the air humidity is confirmed, the corresponding working mode is started according to the air humidity, such as the aforementioned strong working mode and normal working mode. After the working mode is confirmed, the corresponding working mode is selected, and then the fan assembly and the plasma module are started according to the selected working mode. The fan assembly blows the air in the dishwasher to the plasma module. When the airflow passes through the discharge area, the plasma will sterilize the airflow passing through, and the airflow passing through the discharge area will circulate through the discharge area under the restriction of the air duct structure, so that the airflow can be continuously sterilized, thereby improving the cleanliness of the air in the dishwasher.

[0045] The plasma module, cleaning equipment and control method disclosed in the present invention can generate plasma through a discharge component, expand the range of the plasma through a dielectric component, and sterilize the airflow through the plasma to prevent the cleaning equipment from generating odor.

[0046] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
