[0002] In addition to sterilizing cutting boards, knives, and cutlery, knife and cutting board sterilizers generally also have a hot air drying function, which can dry the washed tableware in time, effectively inhibiting bacterial growth and mold, and making it easier to preserve.

[0003] In traditional technology, if it is detected that there are items that have just been placed in the storage area of ​​the knife and cutting board sterilizer, the drying function is activated to dry all the items in the storage area of ​​the knife and cutting board sterilizer.

[0004] However, activating the drying function as soon as it detects items recently placed in the storage area of ​​the knife and cutting board sterilizer can easily lead to unnecessary energy waste. Furthermore, it can easily cause over-drying, resulting in cracking, warping, or other damage to certain tableware such as bamboo or wooden cutting boards, chopsticks, and spoons.

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0041] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. Furthermore, in the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if there is transmission of electrical signals or data between the connected objects.

[0042] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0043] In one embodiment, such as Figure 1 The diagram shows a structural block diagram of a drying device, which includes the following steps:

[0044] The detection device 102 is used to detect the humidity value of each item storage area.

[0045] The detection device 102 is installed in the drying equipment. Specifically, a corresponding detection device can be installed in each item storage area of ​​the drying equipment. The detection device can be used to detect the humidity value of each item storage area.

[0046] In practice, drying equipment can be a knife and cutting board sterilizer, and various item storage areas can be areas for storing various tableware, specifically including cutting board storage areas, knife storage areas, chopsticks and spoon storage areas, etc.

[0047] For example, the detection device 102 can detect the humidity value of each item storage area in real time. In this embodiment, the detection device may include multiple humidity sensors, and each humidity sensor may be set in a corresponding item storage area. That is, the number of humidity sensors in the drying equipment may correspond to the number of item storage areas. Of course, the detection device may also be any detection device, as long as it can detect the humidity value of each item storage area. This application does not limit this.

[0048] Specifically, during the operation of the drying equipment, the detection devices installed in each item storage area can detect each item storage area to collect the corresponding humidity value. The detection device 102 is connected to the controller 104 and can transmit the collected humidity value corresponding to each item storage area to the controller 104.

[0049] The controller 104 is configured to: acquire a first humidity value for each item storage area; determine a target item storage area; the target item storage area being an item storage area whose first humidity value is not less than a first preset value; control a drying device to dry the target item storage area; acquire a second humidity value for the target item storage area; the second humidity value being the humidity value of the target item storage area detected during the drying process; and control the drying device to stop drying the target item storage area if the detected second humidity value is less than a second preset value; the first preset value being greater than the second preset value.

[0050] The humidity value may include a first humidity value and a second humidity value. The first humidity value is the humidity value detected in the storage area of ​​items that are not currently undergoing drying treatment. The second humidity value is the humidity value detected in the target item storage area during the drying treatment process. The target item storage area is an item storage area where the first humidity value is not less than a first preset value.

[0051] For example, in the drying equipment, humidity sensors for each item storage area detect a first humidity value and a second humidity value for each item storage area. The controller 104 acquires the first humidity value for each item storage area. If the first humidity value is not less than a first preset value, it determines the target item storage area that needs drying treatment and performs drying treatment on the target item storage area. During the drying treatment of the target item storage area, the second humidity value of the target item storage area is detected. If the second humidity value of the target item storage area is detected to be less than a second preset value, the controller stops drying treatment on the target item storage area where the second humidity value is less than the second preset value.

[0052] Specifically, the values ​​of the first preset value and the second preset value can be set based on empirical values, as long as the first preset value is greater than the second preset value.

[0053] The drying device 106 is used to dry the target item storage area in response to the control of the controller.

[0054] The drying device is a device that can dry the storage area of ​​the target items. It is understood that in this embodiment, the drying device may include heaters, fans, etc., to achieve the drying treatment of the storage area of ​​the target items.

[0055] In the aforementioned drying equipment, a first humidity value is acquired for each item storage area. The storage area with a first humidity value not less than a first preset value is then identified as the target item storage area. The drying process is controlled to proceed in the target item storage area. During the drying process, a second humidity value is acquired for the target item storage area. If the second humidity value of the target item storage area is detected to be less than a second preset value, the drying process is stopped. This achieves the drying of areas requiring humidity adjustment and timely cessation of the drying process, effectively reducing over-drying and avoiding heat waste.

[0056] In one embodiment, the drying device includes a positive temperature coefficient (PTC) heater; the controller is configured to determine a first demand level information for the target item storage area based on the difference between a first humidity value and a first preset value; and to activate the corresponding fan for the target item storage area based on the first demand level information, and control the PTC heater to be in an on state, so as to control the drying device to dry the target item storage area.

[0057] The drying unit may include a heater and multiple fans. The heater may be a positive temperature coefficient (PTC) heater, and the fans may be variable frequency fans with multiple speed settings. Specifically, the number of fans may correspond to the number of storage areas.

[0058] In practice, if the drying equipment is a knife and cutting board sterilizer, it has two areas: a controller area and a utensil drying and storage area. The utensil drying and storage area can include multiple independent storage zones for different tableware and kitchen utensils. For example, chopsticks are stored in one zone, spoons in another, knives in another, and cutting boards in yet another. Each storage zone is relatively independent and not interconnected, and has a hot air inlet and a dried air outlet. The hot air inlets of all storage zones are connected to a main hot air duct. Crucially, each independent storage zone's air inlet is equipped with a variable frequency fan to control whether air is introduced and the amount of hot air.

[0059] Specifically, you can refer to Figure 2The diagram illustrates the control relationships and hot air flow diagram within the drying equipment. The control relationship involves the controller acquiring humidity values ​​from a humidity sensor. The controller controls the PTC heater and the fans in the air inlet channels of each storage area. The hot air flow diagram shows that outside cold air is heated by the PTC heater and then transferred to the corresponding storage area via the fans in the air inlet channels.

[0060] For example, during the operation of the drying equipment, the controller acquires a first humidity value of the target item storage area. Based on the difference between the first humidity value and a first preset value, it determines the first required level information for the target item storage area. According to this first required level information, the controller activates the corresponding fan for the target item storage area and controls the PTC heater to be in the on state, thereby controlling the drying device to dry the target item storage area. Specifically, because the PTC heater has thermal equilibrium characteristics, when the airflow speed increases, its heat dissipation increases, causing the PTC heater to cool down. Therefore, it automatically increases its heating power to replenish the heat, thereby maintaining a constant hot air temperature. Thus, the larger the difference between the first humidity value and the first preset value, the larger the corresponding first required level information.

[0061] In practice, multiple sets of first humidity values ​​and the correspondence between the difference range of the first preset value and the first demand level information can be preset. Thus, given the difference between the first humidity value and the first preset value, the corresponding first demand level information can be determined based on the magnitude of the difference between the first humidity value and the first preset value.

[0062] In the above embodiments, the first required level information of the target item storage area is determined based on the difference between the first humidity value and the first preset value of the target item storage area. Based on the first required level information, the corresponding fan of the target item storage area is started, and the PTC heater is controlled to be in the on state. Through the PTC heater and the fan, the target item storage area is dried more accurately. Furthermore, the first required level information is determined based on the difference between the first humidity value and the first preset value, thereby improving the drying efficiency of the target item storage area.

[0063] In one embodiment, the controller is further configured to determine the second required level information of the target item storage area based on the difference between the second humidity value and the second preset value, and adjust the fan corresponding to the target item storage area based on the second required level information of the target item storage area, so as to control the drying device to dry the target item storage area.

[0064] The second humidity value is the humidity value of the target item storage area detected during the drying process of the target item storage area.

[0065] For example, during the drying process of the drying equipment, a second humidity value of the target item storage area is acquired. Based on the difference between the second humidity value and a second preset value, a second required humidity level is determined for the target item storage area. The fan speed corresponding to the target item storage area is then adjusted according to this second required humidity level to control the drying process. Specifically, during the drying process, the humidity value gradually decreases. However, if the fan speed corresponding to the target item storage area is too high, over-drying may occur.

[0066] In practice, multiple sets of second humidity values ​​and the correspondence between the difference range of the second preset value and the first demand level information can be preset. Thus, when the difference between the second humidity value and the second preset value is determined, the corresponding second demand level information can be determined according to the magnitude of the difference between the second humidity value and the second preset value.

[0067] In the above embodiments, the second required level information of the target item storage area is determined based on the difference between the second humidity value and the second preset value of the target item storage area. The level of the fan corresponding to the target item storage area is then adjusted according to the second required level information. Through the PTC heater and the fan, the target item storage area is dried more accurately. Furthermore, determining the second required level information based on the difference between the second humidity value and the second preset value effectively reduces the occurrence of over-drying.

[0068] To better understand the drying process of the drying equipment in this embodiment, we will use a knife and cutting board sterilizer as an example. If the item storage area in this knife and cutting board sterilizer includes three sections, these can be designated as a knife area, a cutting board area, and a chopsticks and spoon area, depending on actual usage. The number of item storage areas is not limited to three. Specifically, refer to... Figure 3 The diagram shows the structure of a knife and cutting board sterilizer, including: air outlet 3-1 for the knife area, air outlet 3-2 for the cutting board area, air outlet 3-3 for the chopsticks and spoon area, door panel 3-4 for the chopsticks and spoon area, display area 3-5, and touch button area 3-6. Each storage area has an independent ventilation channel and an independent air outlet for airflow. Display area 3-5 displays the usage status of the knife and cutting board sterilizer. Touch button area 3-6 allows the user to control the start or stop of the sterilizer.

[0069] refer to Figure 4The diagram illustrates the structure of the air inlet in a knife and cutting board sterilizer, including: air inlet 4-1 for the knife area, air inlet 4-2 for the cutting board area, air inlet 4-3 for the chopsticks and spoon area, a PTC heater 4-4, a main controller 4-5, humidity sensors 4-6, 4-7, and 4-8 for the knife, cutting board, and chopsticks and spoon areas. Each storage area has an independent ventilation channel and an independent air inlet to obtain hot air. Each storage area also has an independent humidity sensor, which is located on the side wall of the storage area at a height that can be the middle of the total height of the storage area. Specifically, a first preset value and a second preset value can be set for each storage area based on the type of items stored in each area.

[0070] refer to Figure 5 The diagram shows the structure of another drying device, a knife and cutting board sterilizer, including: an overall air inlet 5-1, a PTC hot air channel 5-2, a main hot air channel 5-3, a variable frequency fan 5-4 for the knife area, a variable frequency fan 5-5 for the chopsticks and spoon area, and a variable frequency fan 5-6 for the cutting board area. The overall air inlet 5-1 is used to achieve overall airflow from the drying device. The PTC hot air channel 5-2 is used to obtain hot air from the PTC heater. The main hot air channel 5-3 is used to receive hot air transferred from the PTC hot air channel. Each item storage area has an independent variable frequency fan; the humidity adjustment speed of the corresponding item storage area is controlled by adjusting the speed of the variable frequency fan.

[0071] refer to Figure 6 The diagram shows the structure of another drying device, a knife and cutting board sterilizer, including a variable frequency fan 6-1 and a check valve 6-2. Each fan corresponds to a check valve, and the variable frequency fan and corresponding check valve for each storage area constitute the air inlet channel switch for that area. Specifically, the check valve prevents air from being directly drawn from the branch ducts of other storage areas when only one storage area's fan is on, without drawing in the hot air heated by the PTC heater from the main duct. If this happens, not only will hot air not be drawn to dry the area, but the PTC heater's thermal protection will be triggered, or the machine may be damaged by high temperature.

[0072] In one embodiment, the controller is configured to: obtain the number of item storage areas currently undergoing drying when a second humidity value of a target item storage area is detected to be less than a second preset value; control the drying device to stop drying the item storage area currently undergoing drying when the number of item storage areas currently undergoing drying is 1; and control the corresponding fan of the target item storage area with a second humidity value less than the second preset value to be turned off when the number of item storage areas currently undergoing drying is not 1 and a second humidity value of a target item storage area is not less than the second preset value.

[0073] For example, if a second humidity value in a target item storage area is detected to be lower than a second preset value, the timing for shutting down the corresponding fan in the target item storage area is determined based on the number of item storage areas currently undergoing drying. Specifically, if there is only one item storage area currently undergoing drying, the drying device is controlled to stop drying the item storage area currently undergoing drying. If there are more than one item storage area currently undergoing drying, and the second humidity value in a target item storage area is not lower than the second preset value, the fan in the target item storage area with a second humidity value lower than the second preset value is controlled to be shut down.

[0074] In the above embodiment, when a second humidity value of a target item storage area is detected to be less than a second preset value, the number of item storage areas currently undergoing drying is used to determine whether to directly shut down the PTC heater. If a target item storage area still has a second humidity value greater than the second preset value, the drying process continues, but the fan in the target item storage area with a second humidity value less than the second preset value needs to be turned off. This achieves drying of areas that require humidity adjustment, effectively reducing over-drying, avoiding heat waste, and thus reducing energy consumption.

[0075] In one embodiment, the controller is configured to control the shutdown of the PTC heater in the drying device, and after a preset time after the PTC heater is shut down, control all fans of the drying device to be in a shut-off state.

[0076] Specifically, if the second humidity value of the target item storage area is detected to be lower than the second preset value, and there is only one item storage area currently undergoing drying, the PTC heater is triggered to shut down. After a preset time following the PTC heater's shutdown, all fans are controlled to be in the off state. The preset time is generally set to 30 seconds. Specifically, the preset time can be set based on empirical values, and this invention does not limit it.

[0077] In the above embodiment, when the second humidity value of the target item storage area is detected to be less than the second preset value, and there is only one item storage area currently undergoing drying, the PTC heater is turned off. After a preset time after the PTC heater is turned off, the corresponding fan is then turned off to achieve heat dissipation protection for the PTC heater, which helps to reduce the possibility of drying equipment failure.

[0078] In one embodiment, such as Figure 7 As shown, a drying control method is provided, including:

[0079] Step 702: Obtain the first humidity value of each item storage area.

[0080] The first humidity value is the humidity level of the storage area for items that have not yet undergone drying.

[0081] Specifically, a humidity detection device, which can be a humidity sensor, can be installed in each storage area.

[0082] Step 704: Determine the target item storage area; the target item storage area is an item storage area with a first humidity value not less than a first preset value.

[0083] The target item storage area can be an item storage area with a first humidity value not less than a first preset value and which has not yet undergone drying treatment.

[0084] Step 706: Dry the target item storage area.

[0085] Specifically, heaters and fans can be deployed in the storage area to dry the target items.

[0086] In practice, a first preset value can be set for each storage area based on the type of items stored there, thereby enabling more precise drying of the items stored in the target storage area.

[0087] Step 708: Obtain the second humidity value of the target item storage area; the second humidity value is the humidity value of the target item storage area detected during the drying process of the target item storage area.

[0088] Step 710: If the second humidity value of the target item storage area is detected to be less than the second preset value, stop the drying process of the target item storage area; wherein the first preset value is greater than the second preset value.

[0089] The second humidity value is the humidity level of the target item storage area detected during the drying process. The first preset value is greater than the second preset value; specifically, the first preset value should be slightly greater than the second preset value.

[0090] For example, humidity sensors in each item storage area detect a first humidity value and a second humidity value for each storage area. If the first humidity value is not less than a first preset value, a target item storage area requiring drying is determined, and this area is then dried. During the drying process, the second humidity value of the target item storage area is detected. If the second humidity value is detected to be less than a second preset value, the drying process for the target item storage area with the second humidity value less than the second preset value is stopped.

[0091] In the above drying control method, the first humidity value of each item storage area is obtained, and the item storage area with the first humidity value not less than the first preset value is determined as the target item storage area, so as to control the drying process of the target item storage area. During the drying process of the target item storage area, the second humidity value of the target item storage area is obtained. If the second humidity value of the target item storage area is detected to be less than the second preset value, the drying process of the target item storage area is stopped. This realizes the drying process of the area that needs humidity adjustment and timely stops the drying process, effectively reducing the occurrence of over-drying and avoiding heat waste.

[0092] In some embodiments, step 706 includes: determining the first demand level information of the target item storage area based on the difference between the first humidity value and the first preset value of the target item storage area;

[0093] Based on the first demand level information of the target item storage area, the corresponding fan of the target item storage area is started, and the PTC heater is turned on to dry the target item storage area.

[0094] In practice, drying equipment can contain heaters and multiple fans. The heaters can be PTC heaters, and the fans can be variable frequency fans with multiple speed settings. Specifically, the number of fans can correspond to the number of storage areas.

[0095] For example, based on the difference between a first humidity value and a first preset value in the target item storage area, a first demand level information for the target item storage area is determined. Based on this first demand level information, the corresponding fan in the target item storage area is activated, and the PTC heater is controlled to be in the on state, thereby achieving the drying process. Specifically, because the PTC heater has thermal equilibrium characteristics, when the airflow speed increases, its heat dissipation increases, causing the PTC heater to cool down. Therefore, the heating power is automatically increased to supplement the heat, thereby maintaining a constant hot air temperature. Thus, the larger the difference between the first humidity value and the first preset value, the larger the corresponding first demand level information.

[0096] Specifically, multiple sets of first humidity values ​​and the correspondence between the difference range of the first preset value and the first demand level information can be preset, so that when the difference between the first humidity value and the first preset value is determined, the corresponding first demand level information can be determined according to the magnitude of the difference between the first humidity value and the first preset value.

[0097] In the above embodiments, the first required level information of the target item storage area is determined based on the difference between the first humidity value and the first preset value of the target item storage area. Based on the first required level information, the corresponding fan of the target item storage area is started, and the PTC heater is controlled to be in the on state. Through the PTC heater and the fan, the target item storage area is dried more accurately. Furthermore, the first required level information is determined based on the difference between the first humidity value and the first preset value, thereby improving the drying efficiency of the target item storage area.

[0098] In some embodiments, step 706 further includes: drying the target item storage area, which further includes:

[0099] Based on the difference between the second humidity value and the second preset value, the second required level information of the target item storage area is determined;

[0100] Based on the second demand level information of the target item storage area, the corresponding fan of the target item storage area is adjusted to dry the target item storage area.

[0101] In practice, multiple sets of second humidity values ​​and the correspondence between the difference range of the second preset value and the first demand level information can be preset. Thus, when the difference between the second humidity value and the second preset value is determined, the corresponding second demand level information can be determined according to the magnitude of the difference between the second humidity value and the second preset value.

[0102] In the above embodiments, the second required level information of the target item storage area is determined based on the difference between the second humidity value and the second preset value of the target item storage area. The level of the fan corresponding to the target item storage area is then adjusted according to the second required level information. Through the PTC heater and the fan, the target item storage area is dried more accurately. Furthermore, determining the second required level information based on the difference between the second humidity value and the second preset value effectively reduces the occurrence of over-drying.

[0103] In some embodiments, step 710 includes:

[0104] If the second humidity value of the target item storage area is detected to be less than the second preset value, the number of item storage areas currently undergoing drying processing is obtained.

[0105] If there is 1 item storage area currently undergoing drying, stop drying the item storage area currently undergoing drying.

[0106] If the number of storage areas for items currently undergoing drying is not 1, and there is a second humidity value in a target item storage area that is not less than a second preset value, control to shut down the corresponding fan in the target item storage area where the second humidity value is less than the second preset value.

[0107] In the above embodiment, when a second humidity value of a target item storage area is detected to be less than a second preset value, the number of item storage areas currently undergoing drying is used to determine whether to directly shut down the PTC heater. If a target item storage area still has a second humidity value greater than the second preset value, the drying process continues, but the fan in the target item storage area with a second humidity value less than the second preset value needs to be turned off. This achieves drying of areas that require humidity adjustment, effectively reducing over-drying, avoiding heat waste, and thus reducing energy consumption.

[0108] In some embodiments, stopping the drying process in an area where items are currently being dried includes:

[0109] The PTC heater is shut down by the control.

[0110] After a preset time following the shutdown of the PTC heater, all fans are controlled to be in the off state.

[0111] Specifically, if the second humidity value of the target item storage area is detected to be lower than the second preset value, and there is only one item storage area currently undergoing drying, the PTC heater is triggered to shut down. After a preset time following the PTC heater's shutdown, all fans are controlled to be in the off state. The preset time is generally set to 30 seconds. Specifically, the preset time can be set based on empirical values, and this invention does not limit it.

[0112] In the above embodiment, when the second humidity value of the target item storage area is detected to be less than the second preset value, and there is only one item storage area currently undergoing drying, the PTC heater is turned off. After a preset time after the PTC heater is turned off, the corresponding fan is then turned off to achieve heat dissipation protection for the PTC heater, which helps to reduce the possibility of drying equipment failure.

[0113] To better understand the complete drying control process in the embodiments of the present invention, a complete example is provided for illustration. (Refer to...) Figure 8 The diagram illustrates a flow chart of a drying control method in another embodiment, including the following steps:

[0114] Step 802: Detect the humidity value of each item storage area.

[0115] Step 804: Determine if the humidity of the storage area for items is not less than a first preset value. If it is, proceed to step 806; otherwise, proceed to step 802. Specifically, detect the humidity value of the storage area for items that have not yet undergone drying treatment.

[0116] Step 806: Control the fan in the storage area of ​​items with humidity values ​​greater than the first preset value to be turned on.

[0117] Step 808: Control the PTC heater to be in the on state. Specifically, control the PTC heater to start or keep the PTC heater on.

[0118] Step 810: Determine if the humidity in the target item storage area is lower than the second preset value. If it is, proceed to step 812; otherwise, proceed to step 806.

[0119] Step 812: Determine if the current quantity of the target item storage area is 1. If the current quantity of the target item storage area is 1, proceed to step 816; if the current quantity of the target item storage area is not 1, proceed to step 814.

[0120] Step 814: Control the shutdown of the corresponding fan in the target item storage area where the second humidity value is less than the second preset value.

[0121] Step 816: Control the PTC heater to shut down.

[0122] Step 818: 30 seconds after the PTC heater is turned off, control all fans to be in the off state.

[0123] To better understand the complete process of the drying control method in the embodiments of the present invention, a complete example is provided for illustration. (Refer to...) Figure 9 The diagram illustrates a flow chart of a drying control method in yet another embodiment, including the following steps:

[0124] Step 902: Obtain the first humidity value of each item storage area.

[0125] Step 904: Determine the storage area for items with a first humidity value not less than a first preset value as the target storage area.

[0126] Step 906: Determine the first required level information of the target item storage area based on the difference between the first humidity value and the first preset value of the target item storage area; based on the first required level information of the target item storage area, control the start of the corresponding fan of the target item storage area and control the PTC heater to be in the on state to dry the target item storage area.

[0127] Step 908: Determine the second required level information of the target item storage area based on the difference between the second humidity value and the second preset value; adjust the fan corresponding to the target item storage area according to the second required level information of the target item storage area to dry the target item storage area.

[0128] Step 910: Obtain the second humidity value of the target item storage area.

[0129] Step 912: If the second humidity value of the target item storage area is less than the second preset value, obtain the number of item storage areas currently undergoing drying treatment.

[0130] Step 914: If the number of item storage areas currently undergoing drying is 1, control the PTC heater to be turned off; after a preset time after the PTC heater is turned off, control all fans to be in the off state; if the number of item storage areas currently undergoing drying is not 1, and there is a target item storage area with a second humidity value not less than a second preset value, control the corresponding fan in the target item storage area with a second humidity value less than the second preset value to be turned off.

[0131] In this embodiment, by acquiring the first humidity value of each item storage area, the item storage area with a first humidity value not less than a first preset value is determined as the target item storage area, so as to control the drying process of the target item storage area. During the drying process of the target item storage area, the second humidity value of the target item storage area is acquired. If the second humidity value of the target item storage area is detected to be less than the second preset value, the drying process of the target item storage area is stopped. This realizes the drying process of the area that needs humidity adjustment and timely stops the drying process, effectively reducing the occurrence of over-drying and avoiding heat waste.
