Description

Technical Field

[0001] The present invention relates to the technical field of heating equipment, and in particular to a control method and device for heating equipment, a readable storage medium, and a heating equipment. Background Art

[0002] In the related art, in heating equipment without a thermostat, such as a disinfection cabinet, the temperature is controlled by controlling the working time of the heating wire during the heating and disinfection process.

[0003] However, general heating equipment controls heating through a preset fixed heating time, resulting in inaccurate heating control and poor temperature control effect. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present invention provides a method for controlling a heating device.

[0006] A second aspect of the present invention provides a control device for a heating device.

[0007] A third aspect of the present invention provides a control device for a heating device.

[0008] A fourth aspect of the present invention provides a readable storage medium.

[0009] A fifth aspect of the present invention provides a heating device.

[0010] In view of this, the first aspect of the present invention provides a control method for a heating device, wherein the heating device includes a heating element, and the control method includes: obtaining the temperature change rate of the heating device in response to a start-up instruction; determining the working time of the heating element based on the temperature change rate; and controlling the operation of the heating element based on the working time.

[0011] In this technical solution, the heating device is specifically a disinfection cabinet, which includes a heating element. The heating element can be an electric heating element or a hot air component. By controlling the heating element to be powered on and heated to generate high temperature, the high temperature is used to kill microorganisms such as bacteria and viruses, thereby achieving sterilization and disinfection. Specifically, during the operation of the heating device, after receiving a start command, the heating element is controlled to be powered on, wherein a relay can be set between the heating element and the power supply. When the heating element is required to work, the relay is closed, the heating element is connected to the power supply, and the power supply provides electrical energy to the heating element, thereby controlling the operation of the heating element. When the heating element is required to stop working, the relay is disconnected, the heating element is disconnected from the power supply, and heating stops.

[0012] Generally speaking, when using a heating device for disinfection, in order to ensure the disinfection effect, it is also necessary to prevent high temperatures from damaging the objects being disinfected, such as plastic tableware and glassware. Therefore, the temperature inside the heating device needs to be maintained within a suitable range. Low-cost heating devices do not have a dedicated temperature control module, so the temperature cannot be maintained by adjusting the heating power of the heating element. Instead, the operating time of the heating element must be adjusted to maintain the temperature within a certain range.

[0013] For example, the target disinfection temperature range of the heating device is A℃ to B℃, and A>B. Then the heating element of the heating device can be controlled to continue heating within X minutes to increase the temperature inside the heating device to A℃. After that, the heating element of the heating device can be controlled to stop heating within Y minutes to slowly drop the temperature of the heating device to B degrees Celsius.

[0014] Among them, the heating power of the heating element is fixed, and the temperature change in the heating device will vary with the environment. Therefore, the temperature change caused by the same heating time may be different. In this regard, after receiving the start instruction, the embodiment of the present application first obtains the temperature change rate corresponding to the heating device. The temperature change rate indicates the rate of increase or decrease of the temperature in the heating device when the heating element of the heating device is working or not working under the current environment of the heating device. In other words, based on the temperature change rate, it is possible to determine the time required for the heating device to raise the internal temperature to the upper limit of the target temperature range, the working time required for the heating element, and the time it takes for the internal temperature of the heating device to naturally drop to the lower limit of the target temperature range after the heating element stops working.

[0015] Therefore, the working time of the heating element is determined according to the temperature change rate, and the heating element of the heating device is controlled to work based on the working time, so that the internal temperature of the heating device can be accurately controlled within the appropriate disinfection temperature range. On the one hand, it avoids excessively high temperature and prevents the heating device from causing damage to the object being disinfected. On the other hand, it can effectively ensure the disinfection temperature and avoid excessively low temperature, thereby ensuring the disinfection effect.

[0016] The embodiment of the present application determines the target working time of the heating element of the heating device according to the temperature change rate corresponding to the current environment of the heating device, and controls the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

[0017] In addition, the control method of the heating device in the above technical solution provided by the present invention may also have the following additional technical features:

[0018] In the above technical solution, the temperature change rate includes the heating rate and the cooling rate.

[0019] In this technical solution, during the operation of the heating element of the heating device, the heating element releases heat and causes the temperature inside the heating device to rise. When the heating element stops working, since the temperature inside the heating device is higher than the ambient temperature, the heat inside the heating device will gradually dissipate into the environment, causing the temperature inside the heating device to naturally drop.

[0020] In this process, the rate of temperature rise is affected by the ambient temperature on the one hand and the heating power of the heating element on the other hand, while the rate of temperature drop is affected by the ambient temperature and the thermal insulation performance of the heating equipment.

[0021] Therefore, the temperature rise rate and temperature drop rate of the heating device are not the same. The embodiment of the present application respectively obtains the heating rate and the cooling rate of the heating device, thereby setting the working time of the heating element, and controlling the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

[0022] In any of the above technical solutions, obtaining the temperature change rate of the heating device includes: obtaining the ambient temperature; and determining the temperature change rate according to the ambient temperature.

[0023] In this technical solution, the temperature change rate inside the heating device specifically includes the heating device's heating rate and the heating device's cooling rate. When the heating device heats up, the heating element operates and releases heat, causing the temperature inside the heating device to rise. During this process, before the heating element operates, the temperature inside the heating device is close to the ambient temperature. When the heating power of the heating element is fixed, the lower the ambient temperature, the slower the heating rate. Therefore, the heating rate is affected by the ambient temperature.

[0024] At the same time, when the heating device stops heating and cools down, because the temperature inside the heating device is higher than the ambient temperature, the heat inside the heating device will gradually dissipate into the environment, causing the temperature inside the heating device to naturally drop. During this process, the lower the ambient temperature, the greater the temperature difference between the heating device and the ambient temperature, and therefore the faster the temperature drop. Therefore, the cooling rate is also affected by the ambient temperature.

[0025] It can be seen that the heating rate and cooling rate of the heating equipment are both related to the ambient temperature. Therefore, by collecting the ambient temperature and determining the heating rate and cooling rate of the heating equipment according to the ambient temperature, the actual temperature change rate of the heating equipment under the current environmental conditions can be accurately reflected, thereby determining the working time of the heating element according to the temperature change rate, and accurately controlling the internal temperature of the heating equipment so that the internal temperature is controlled within the appropriate disinfection temperature range, avoiding excessively high temperature, and preventing the heating equipment from causing damage to the object being disinfected. At the same time, it can effectively ensure the disinfection temperature and ensure the disinfection effect.

[0026] It is understood that in some embodiments, the heating device can collect ambient temperature information using its own ambient temperature sensor. In other embodiments, the heating device can obtain ambient temperature information collected by other smart home devices through the Internet of Things, such as air conditioners, air purifiers, and fresh air blowers. This eliminates the need for a separate temperature sensor for the heating device, optimizing the structure and cost of the heating device.

[0027] In any of the above technical solutions, the temperature change rate is determined according to the ambient temperature, including: obtaining a preset heating rate, a preset cooling rate, a heating coefficient and a cooling coefficient; determining the heating rate according to the ambient temperature, the preset heating rate and the heating coefficient; determining the cooling rate according to the ambient temperature, the preset cooling rate and the cooling coefficient.

[0028] In this technical solution, when determining the temperature change rate, the temperature rise coefficient of the heating device and the temperature drop coefficient of the heating device can be determined respectively according to the current ambient temperature.

[0029] Specifically, first, obtain the preset heating rate and preset cooling rate of the heating device, and obtain the heating coefficient and cooling coefficient of the heating device. The preset heating rate and preset cooling rate are obtained through experiments at the factory and can reflect the heating rate and cooling rate of the heating device in most cases. The preset heating rate and preset cooling rate can be the heating rate and cooling rate experimentally measured when the ambient temperature is within the range of 24°C to 26°C.

[0030] The temperature rise coefficient specifically reflects the heating capacity of a heating element in a heating device. The greater the heating power of the heating element, the greater the heating capacity and the larger the temperature rise coefficient. This coefficient is related to the model, parameters, and power of the heating element. Therefore, once the heating element is selected, the temperature rise coefficient of the heating device is fixed. Therefore, this coefficient can be preset in the heating device controller during production.

[0031] The cooling coefficient specifically reflects the thermal insulation capacity of the cabinet of the heating equipment. The better the thermal insulation capacity of the cabinet, the less likely the heat in the heating equipment is to dissipate outside the cabinet, and the lower the cooling coefficient.

[0032] According to the actual ambient temperature of the environment in which the heating device is currently located, the pre-stored preset heating rate, and the pre-stored heating coefficient, the heating rate of the heating device in the current environment can be accurately calculated.

[0033] At the same time, based on the actual ambient temperature of the environment in which the heating device is currently located, the pre-stored preset cooling rate, and the pre-stored cooling coefficient, the cooling rate of the heating device in the current environment can be accurately calculated.

[0034] The embodiment of the present application accurately calculates the heating rate and cooling rate of the heating device to obtain the temperature change rate corresponding to the current environment of the heating device, so as to determine the target working time of the heating element of the heating device, and controls the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

[0035] In any of the above technical solutions, determining the heating rate according to the ambient temperature, the preset heating rate and the heating coefficient includes:

[0036] The heating rate is calculated using the following formula:

[0037] Vr=Vr1+(T-26)×Kr;

[0038] Wherein, Vr is the heating rate, Vr1 is the preset heating rate, T is the ambient temperature, and Kr is the heating coefficient.

[0039] In this technical solution, taking 26°C as the reference temperature, the difference between the current ambient temperature T and the reference temperature is first calculated, and then the product of the difference and the temperature rise coefficient is calculated to obtain the difference between the heating rate at the current room temperature and the preset heating rate at the reference temperature, and the preset heating rate at the reference temperature is compensated accordingly, so as to obtain the accurate heating rate of the heating device at the current ambient temperature. The heating working time of the heating element is determined by the heating rate, and the heating element of the heating device is controlled to work based on the working time, so that the internal temperature of the heating device can be accurately controlled within the appropriate disinfection temperature range to ensure the disinfection effect.

[0040] In any of the above technical solutions, the cooling rate is determined according to the ambient temperature, the preset cooling rate and the cooling coefficient, including:

[0041] The cooling rate is calculated using the following formula:

[0042] Vd=Vd1+(26-T)×Kd;

[0043] Wherein, Vd is the cooling rate, Vd1 is the preset cooling rate, T is the ambient temperature, and Kd is the cooling coefficient.

[0044] In this technical solution, taking 26°C as the reference temperature, the difference between the current ambient temperature T and the reference temperature is first calculated, and then the product of the difference and the cooling coefficient is calculated to obtain the difference between the cooling rate at the current room temperature and the preset cooling rate at the reference temperature, and the preset cooling rate at the reference temperature is compensated accordingly, so as to obtain the accurate cooling rate of the heating equipment at the current ambient temperature. The working time of the heating element when it stops heating is determined by the cooling rate, and the heating element of the heating equipment is controlled to work based on the working time, so that the internal temperature of the heating equipment can be accurately controlled within the appropriate disinfection temperature range to ensure the disinfection effect.

[0045] In any of the above technical solutions, obtaining the temperature change rate of the heating device further includes: obtaining time information when the ambient temperature is not obtained; and determining the temperature change rate based on the time information.

[0046] In this technical solution, if the current heating device cannot obtain the actual ambient temperature, such as there is no temperature sensor installed on the heating device, or the network module of the heating device cannot be connected to the Internet normally, or there is no smart home device that can obtain the ambient temperature in the network environment or the Internet of Things where the heating device is located, the corresponding temperature change rate can be determined by time information.

[0047] Specifically, the time information includes season information and time period information. The format of the time information can be the "year-month-day" time format. The control device of the heating device can have a built-in time module, and an initial time is set at the factory. The time module automatically counts and records the current time information.

[0048] In other embodiments, the heating device can access a time server via a wireless network to obtain more accurate time information. The time server can be a network server, a gateway, a user's mobile phone, or other smart home device, which is not limited in this application.

[0049] Since the ambient temperature is different in different seasons and time periods, the corresponding temperature change rate will also be different. In the embodiment of the present application, different temperature change rates are preset for different seasons and time periods.

[0050] For example, according to the season, a year is divided into four seasons: spring (such as March to May), summer (such as June to August), autumn (such as September to November), and winter (such as December to February). According to the time period, a day is divided into daytime (8:00 to 20:00) and night (such as 21:00 to 7:00).

[0051] A corresponding temperature change rate is set for each time period in each season, so there are a total of 8 preset temperature change rates for different time periods in different seasons. After obtaining the current time information, the heating device determines the preset temperature change rate by looking up the table based on the current season and time period. This is then determined as the temperature change rate that currently controls the operation of the heating device, as well as the corresponding operating time. Based on this operating time, the heating element of the heating device is controlled to operate, enabling the heating device to accurately control its internal temperature within the appropriate disinfection temperature range, ensuring the disinfection effect.

[0052] In any of the above technical solutions, obtaining the temperature change rate of the heating device also includes: when the ambient temperature and time information are not obtained, determining the preset heating rate as the heating rate, and determining the preset cooling rate as the cooling rate.

[0053] In this technical solution, if the heating device cannot obtain the actual ambient temperature or the current accurate time information, the preset heating rate and the preset cooling rate calibrated at the factory are directly used as the temperature change rate to control the operation of the heating device, thereby determining the working time of the heating element. Among them, the preset heating rate and the preset cooling rate are obtained through experiments at the factory and can reflect the heating rate and the cooling rate of the heating device in most cases. Among them, the preset heating rate and the preset cooling rate can be the heating rate and the cooling rate measured experimentally when the ambient temperature is in the range of 24°C to 26°C.

[0054] In any of the above technical solutions, the working time includes a first time and a second time, the first time indicates the time during which the heating element continues to work, and the second time indicates the time during which the heating element stops working.

[0055] In this technical solution, the operating duration specifically includes a first duration for instructing the heating element to heat, and a second duration for instructing the heating element to stop heating. During operation of the heating device, the heating element is first controlled to continue heating for the first duration. After the operating duration of the heating element reaches the first duration, that is, after the temperature in the heating device reaches the upper limit of the target temperature range, the heating element is controlled to stop heating for the next second duration. At this time, the relay connected to the heating element can be controlled to disconnect.

[0056] After the time period after the heating element stops heating reaches the second time period, the control relay is turned on. At this time, the heating element continues to work again within the next first time period, and the cycle continues.

[0057] The embodiment of the present application determines the first duration of continuous operation of the heating element and the second duration of stopping operation of the heating element based on the temperature change rate, and controls the operation of the heating element of the heating device based on the first duration and the second duration, so that the internal temperature of the heating device can be accurately controlled within a suitable disinfection temperature range. On the one hand, it avoids excessively high temperatures and prevents the heating device from causing damage to the disinfected object. On the other hand, it can effectively ensure the disinfection temperature and avoid excessively low temperatures, thereby ensuring the disinfection effect.

[0058] In any of the above technical solutions, the working time of the heating element is determined according to the temperature change rate, including: determining the first target temperature and the second target temperature according to the start-up instruction, the first target temperature being greater than the second target temperature; determining the first time according to the first target temperature, the ambient temperature and the heating rate; determining the second time according to the first target temperature, the second target temperature and the cooling rate.

[0059] In this technical solution, the first target temperature is the upper limit temperature of the target temperature range when the heating device is disinfected, and the second target temperature is the lower limit temperature of the target temperature range when the poison cabinet is disinfected.

[0060] When determining the first duration, that is, the duration during which the heating element continues to work, the first duration Tr is calculated based on the first target temperature Tg1, the obtained ambient temperature T and the calculated heating rate Vr.

[0061] It is understandable that when the ambient temperature cannot be obtained, calculation can be performed using a pre-stored preset temperature.

[0062] The specific calculation formula is as follows:

[0063] Tr=(Tg1-T)÷Vr;

[0064] Wherein, Tr is the first duration, Tg1 is the first target temperature, Vr is the heating rate, and T is the ambient temperature.

[0065] When determining the second duration, that is, the duration during which the heating element stops working, the second duration Td is calculated based on the first target temperature Tg1, the second target temperature Tg2 and the calculated cooling rate Vd.

[0066] The specific calculation formula is as follows:

[0067] Td=(Tg1–Tg2)÷Vd;

[0068] Wherein, Td is the second time duration, Tg1 is the first target temperature, Tg2 is the second target temperature, and Vd is the cooling rate.

[0069] In any of the above technical solutions, obtaining the ambient temperature includes: sending a query instruction to the target device, where the query instruction is used to control the target device to send the ambient temperature to the heating device; and receiving the ambient temperature.

[0070] In this technical solution, the target device can be a network server that stores bindings between the heating device and any other household devices capable of obtaining ambient temperature information within the home environment in which the heating device is located. For example, the heating device sends a query command to the network server. Based on the query command, the network server requests the air conditioner in the home environment to proactively report the ambient temperature. After the air conditioner reports the ambient temperature, the server forwards the temperature to the heating device. It is understood that if the air conditioner does not report the ambient temperature within a preset time, the network server can request the next household device, such as an air purifier, to report the ambient temperature.

[0071] The target device can also be other household appliances in the same IoT environment as the heating device, such as air conditioners. The heating device sends a query instruction to the air conditioner through the IoT. The air conditioner calls its own temperature detection module to obtain the ambient temperature based on the received query instruction and sends it to the heating device.

[0072] The target device can also be the user's mobile phone. The heating device sends a query instruction to the user's mobile phone APP (Application). The mobile phone APP can collect the ambient temperature based on its own sensors, or obtain the regional ambient temperature through the Internet, or obtain the ambient temperature through other home devices bound to the APP, and send it to the heating device.

[0073] The embodiment of the present application initiates a query to the target device and obtains the ambient temperature through the target device, so that the heating device does not need to be equipped with an independent temperature sensor, thereby optimizing the structure and cost of the heating device.

[0074] The second aspect of the present invention provides a control device for a heating device, wherein the heating device includes a heating element, and the control device includes: an acquisition module for acquiring the temperature change rate of the heating device in response to a start-up instruction; a determination module for determining the working time of the heating element based on the temperature change rate; and a control module for controlling the operation of the heating element based on the working time.

[0075] In this technical solution, the heating device includes a heating element, which can be an electric heating element or a hot air component. By controlling the heating element to be powered on and heated to generate high temperature, the high temperature is used to kill microorganisms such as bacteria and viruses, thereby achieving sterilization and disinfection. Specifically, during the operation of the heating device, after receiving a start-up command, the heating element is controlled to be powered on, wherein a relay can be set between the heating element and the power supply. When the heating element is required to work, the relay is closed, the heating element is connected to the power supply, and the power supply provides electrical energy to the heating element, thereby controlling the operation of the heating element. When the heating element is required to stop working, the relay is disconnected, the heating element is disconnected from the power supply, and heating stops.

[0076] Generally speaking, when using a heating device for disinfection, in order to ensure the disinfection effect, it is also necessary to prevent high temperatures from damaging the objects being disinfected, such as plastic tableware and glassware. Therefore, the temperature inside the heating device needs to be maintained within a suitable range. Low-cost heating devices do not have a dedicated temperature control module, so the temperature cannot be maintained by adjusting the heating power of the heating element. Instead, the operating time of the heating element must be adjusted to maintain the temperature within a certain range.

[0077] For example, the target disinfection temperature range of the heating device is A℃ to B℃, and A>B. Then the heating element of the heating device can be controlled to continue heating within X minutes to increase the temperature inside the heating device to A℃. After that, the heating element of the heating device can be controlled to stop heating within Y minutes to slowly drop the temperature of the heating device to B degrees Celsius.

[0078] Among them, the heating power of the heating element is fixed, and the temperature change in the heating device will vary with the environment. Therefore, the temperature change caused by the same heating time may be different. In this regard, after receiving the start instruction, the embodiment of the present application first obtains the temperature change rate corresponding to the heating device. The temperature change rate indicates the rate of increase or decrease of the temperature in the heating device when the heating element of the heating device is working or not working under the current environment of the heating device. In other words, based on the temperature change rate, it is possible to determine the time required for the heating device to raise the internal temperature to the upper limit of the target temperature range, the working time required for the heating element, and the time it takes for the internal temperature of the heating device to naturally drop to the lower limit of the target temperature range after the heating element stops working.

[0079] Therefore, the working time of the heating element is determined according to the temperature change rate, and the heating element of the heating device is controlled to work based on the working time, so that the internal temperature of the heating device can be accurately controlled within the appropriate disinfection temperature range. On the one hand, it avoids excessively high temperature and prevents the heating device from causing damage to the object being disinfected. On the other hand, it can effectively ensure the disinfection temperature and avoid excessively low temperature, thereby ensuring the disinfection effect.

[0080] The embodiment of the present application determines the target working time of the heating element of the heating device according to the temperature change rate corresponding to the current environment of the heating device, and controls the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

Therefore, the control device of the heating device also includes all the beneficial effects of the control method for a heating device provided in any of the above technical solutions. To avoid repetition, they will not be repeated here.

When the program or instruction is executed by a processor, the steps of the control method of the heating device provided in any of the above technical solutions are implemented. Therefore, the readable storage medium also includes all the beneficial effects of the control method of the heating device provided in any of the above technical solutions.

[0090] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0091] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0092] Refer to the following Figures 1 to 5 The present invention describes a control method and apparatus for a heating device, a readable storage medium, and a heating device according to some embodiments of the present invention.

[0093] Example 1

[0094] like Figure 1 As shown, in some embodiments of the present invention, a method for controlling a heating device is provided. Figure 1 FIG. 1 shows one of the flow charts of the control method of the heating device according to an embodiment of the present invention. Figure 1 As shown, the method includes:

[0095] Step 102, after receiving the start instruction, obtaining the temperature change rate of the heating device;

[0096] Step 104, determining the operating time of the heating element according to the temperature change rate;

[0097] Step 106: Control the operation of the heating element according to the operation duration.

[0098] In an embodiment of the present invention, the heating device includes a heating element, which can be an electric heating element or a hot air component. By controlling the heating element to be powered on and heated to generate high temperature, the high temperature is used to kill microorganisms such as bacteria and viruses, thereby achieving sterilization and disinfection. Specifically, during the operation of the heating device, after receiving a start-up instruction, the heating element is controlled to be powered on, wherein a relay can be set between the heating element and the power supply. When the heating element is required to work, the relay is closed, the heating element is connected to the power supply, and the power supply provides electrical energy to the heating element, thereby controlling the operation of the heating element. When the heating element is required to stop working, the relay is disconnected, the heating element is disconnected from the power supply, and heating stops.

[0099] Generally speaking, when using a heating device for disinfection, in order to ensure the disinfection effect, it is also necessary to prevent high temperatures from damaging the objects being disinfected, such as plastic tableware and glassware. Therefore, the temperature inside the heating device needs to be maintained within a suitable range. Low-cost heating devices do not have a dedicated temperature control module, so the temperature cannot be maintained by adjusting the heating power of the heating element. Instead, the operating time of the heating element must be adjusted to maintain the temperature within a certain range.

[0100] For example, the target disinfection temperature range of the heating device is A℃ to B℃, and A>B. Then the heating element of the heating device can be controlled to continue heating within X minutes to increase the temperature inside the heating device to A℃. After that, the heating element of the heating device can be controlled to stop heating within Y minutes to slowly drop the temperature of the heating device to B degrees Celsius.

[0101] Among them, the heating power of the heating element is fixed, and the temperature change in the heating device will vary with the environment. Therefore, the temperature change caused by the same heating time may be different. In this regard, after receiving the start instruction, the embodiment of the present application first obtains the temperature change rate corresponding to the heating device. The temperature change rate indicates the rate of increase or decrease of the temperature in the heating device when the heating element of the heating device is working or not working under the current environment of the heating device. In other words, based on the temperature change rate, it is possible to determine the time required for the heating device to raise the internal temperature to the upper limit of the target temperature range, the working time required for the heating element, and the time it takes for the internal temperature of the heating device to naturally drop to the lower limit of the target temperature range after the heating element stops working.

[0102] Therefore, the working time of the heating element is determined according to the temperature change rate, and the heating element of the heating device is controlled to work based on the working time, so that the internal temperature of the heating device can be accurately controlled within the appropriate disinfection temperature range. On the one hand, it avoids excessively high temperature and prevents the heating device from causing damage to the object being disinfected. On the other hand, it can effectively ensure the disinfection temperature and avoid excessively low temperature, thereby ensuring the disinfection effect.

[0103] The embodiment of the present application determines the target working time of the heating element of the heating device according to the temperature change rate corresponding to the current environment of the heating device, and controls the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

[0104] In some embodiments of the present invention, the temperature change rate includes a heating rate and a cooling rate.

[0105] In an embodiment of the present invention, during the operation of the heating element of the heating device, the heating element releases heat and causes the temperature inside the heating device to rise. When the heating element stops working, since the temperature inside the heating device is higher than the ambient temperature, the heat inside the heating device will gradually dissipate into the environment, causing the temperature inside the heating device to naturally drop.

[0106] In this process, the rate of temperature rise is affected by the ambient temperature on the one hand and the heating power of the heating element on the other hand, while the rate of temperature drop is affected by the ambient temperature and the thermal insulation performance of the heating equipment.

[0107] Therefore, the temperature rise rate and temperature drop rate of the heating device are not the same. The embodiment of the present application respectively obtains the heating rate and the cooling rate of the heating device, thereby setting the working time of the heating element, and controlling the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

[0108] In some embodiments of the present invention, Figure 2 FIG. 2 shows a second flow chart of a method for controlling a heating device according to an embodiment of the present invention. Figure 2 As shown, obtaining the temperature change rate of the heating device includes:

[0109] Step 202, obtaining the ambient temperature;

[0110] Step 204: Determine the temperature change rate according to the ambient temperature.

[0111] In the embodiments of the present invention, the temperature change rate within the heating device specifically includes the heating rate of the heating device and the cooling rate of the heating device. When the heating device heats up, the heating element operates and releases heat, causing the temperature within the heating device to rise. During this process, before the heating element operates, the temperature within the heating device is close to the ambient temperature. When the heating power of the heating element is fixed, the lower the ambient temperature, the slower the heating rate. Therefore, the heating rate is affected by the ambient temperature.

[0112] At the same time, when the heating device stops heating and cools down, because the temperature inside the heating device is higher than the ambient temperature, the heat inside the heating device will gradually dissipate into the environment, causing the temperature inside the heating device to naturally drop. During this process, the lower the ambient temperature, the greater the temperature difference between the heating device and the ambient temperature, and therefore the faster the temperature drop. Therefore, the cooling rate is also affected by the ambient temperature.

[0113] It can be seen that the heating rate and cooling rate of the heating equipment are both related to the ambient temperature. Therefore, by collecting the ambient temperature and determining the heating rate and cooling rate of the heating equipment according to the ambient temperature, the actual temperature change rate of the heating equipment under the current environmental conditions can be accurately reflected, thereby determining the working time of the heating element according to the temperature change rate, and accurately controlling the internal temperature of the heating equipment so that the internal temperature is controlled within the appropriate disinfection temperature range, avoiding excessively high temperature, and preventing the heating equipment from causing damage to the object being disinfected. At the same time, it can effectively ensure the disinfection temperature and ensure the disinfection effect.

[0114] It is understood that in some embodiments, the heating device can collect ambient temperature information using its own ambient temperature sensor. In other embodiments, the heating device can obtain ambient temperature information collected by other smart home devices through the Internet of Things, such as air conditioners, air purifiers, and fresh air blowers. This eliminates the need for a separate temperature sensor for the heating device, optimizing the structure and cost of the heating device.

[0115] In some embodiments of the present invention, the temperature change rate is determined according to the ambient temperature, including: obtaining a preset heating rate, a preset cooling rate, a heating coefficient and a cooling coefficient; determining the heating rate according to the ambient temperature, the preset heating rate and the heating coefficient; determining the cooling rate according to the ambient temperature, the preset cooling rate and the cooling coefficient.

[0116] In the embodiment of the present invention, when determining the temperature change rate, the temperature rise coefficient of the heating device and the temperature drop coefficient of the heating device may be determined respectively according to the current ambient temperature.

[0117] Specifically, first, obtain the preset heating rate and preset cooling rate of the heating device, and obtain the heating coefficient and cooling coefficient of the heating device. The preset heating rate and preset cooling rate are obtained through experiments at the factory and can reflect the heating rate and cooling rate of the heating device in most cases. The preset heating rate and preset cooling rate can be the heating rate and cooling rate experimentally measured when the ambient temperature is within the range of 24°C to 26°C.

[0118] The temperature rise coefficient specifically reflects the heating capacity of a heating element in a heating device. The greater the heating power of the heating element, the greater the heating capacity and the larger the temperature rise coefficient. This coefficient is related to the model, parameters, and power of the heating element. Therefore, once the heating element is selected, the temperature rise coefficient of the heating device is fixed. Therefore, this coefficient can be preset in the heating device controller during production.

[0119] The cooling coefficient specifically reflects the thermal insulation capacity of the cabinet of the heating equipment. The better the thermal insulation capacity of the cabinet, the less likely the heat in the heating equipment is to dissipate outside the cabinet, and the lower the cooling coefficient.

[0120] According to the actual ambient temperature of the environment in which the heating device is currently located, the pre-stored preset heating rate, and the pre-stored heating coefficient, the heating rate of the heating device in the current environment can be accurately calculated.

[0121] At the same time, based on the actual ambient temperature of the environment in which the heating device is currently located, the pre-stored preset cooling rate, and the pre-stored cooling coefficient, the cooling rate of the heating device in the current environment can be accurately calculated.

[0122] The embodiment of the present application accurately calculates the heating rate and cooling rate of the heating device to obtain the temperature change rate corresponding to the current environment of the heating device, so as to determine the target working time of the heating element of the heating device, and controls the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

[0123] In some embodiments of the present invention, determining the heating rate according to the ambient temperature, the preset heating rate, and the heating coefficient includes:

[0124] The heating rate is calculated using the following formula:

[0125] Vr=Vr1+(T-26)×Kr;

[0126] Wherein, Vr is the heating rate, Vr1 is the preset heating rate, T is the ambient temperature, and Kr is the heating coefficient.

[0127] In an embodiment of the present invention, taking 26°C as the reference temperature, the difference between the current ambient temperature T and the reference temperature is first calculated, and then the product of the difference and the temperature rise coefficient is calculated to obtain the difference between the heating rate at the current room temperature and the preset heating rate at the reference temperature, and the preset heating rate at the reference temperature is compensated accordingly, thereby obtaining the accurate heating rate of the heating device at the current ambient temperature. The heating working time of the heating element is determined by the heating rate, and the heating element of the heating device is controlled to work based on the working time, which can enable the heating device to accurately control its internal temperature within the appropriate disinfection temperature range to ensure the disinfection effect.

[0128] In some embodiments of the present invention, determining the cooling rate according to the ambient temperature, the preset cooling rate, and the cooling coefficient includes:

[0129] The cooling rate is calculated using the following formula:

[0130] Vd=Vd1+(26-T)×Kd;

[0131] Wherein, Vd is the cooling rate, Vd1 is the preset cooling rate, T is the ambient temperature, and Kd is the cooling coefficient.

[0132] In an embodiment of the present invention, taking 26°C as the reference temperature, the difference between the current ambient temperature T and the reference temperature is first calculated, and then the product of the difference and the cooling coefficient is calculated to obtain the difference between the cooling rate at the current room temperature and the preset cooling rate at the reference temperature, and the preset cooling rate at the reference temperature is compensated accordingly, thereby obtaining the accurate cooling rate of the heating device at the current ambient temperature. The working time of the heating element when it stops heating is determined by the cooling rate, and the heating element of the heating device is controlled to work based on the working time, so that the internal temperature of the heating device can be accurately controlled within the appropriate disinfection temperature range to ensure the disinfection effect.

[0133] In some embodiments of the present invention, Figure 3 FIG. 3 shows a flow chart of a control method for a heating device according to an embodiment of the present invention. Figure 3 As shown, obtaining the temperature change rate of the heating device also includes:

[0134] Step 302: If the ambient temperature is not obtained, obtain time information;

[0135] Step 304: Determine the temperature change rate based on the time information.

[0136] In an embodiment of the present invention, if the current heating device cannot obtain the actual ambient temperature, such as no temperature sensor is set on the heating device, or the network module of the heating device cannot be connected to the Internet normally, or there is no smart home device that can obtain the ambient temperature in the network environment or the Internet of Things where the heating device is located, the corresponding temperature change rate can be determined by time information.

[0137] Specifically, the time information includes season information and time period information. The format of the time information can be the "year-month-day" time format. The control device of the heating device can have a built-in time module, and an initial time is set at the factory. The time module automatically counts and records the current time information.

[0138] In other embodiments, the heating device can access a time server via a wireless network to obtain more accurate time information. The time server can be a network server, a gateway, a user's mobile phone, or other smart home device, which is not limited in this application.

[0139] Since the ambient temperature is different in different seasons and time periods, the corresponding temperature change rate will also be different. In the embodiment of the present application, different temperature change rates are preset for different seasons and time periods.

[0140] For example, according to the season, a year is divided into four seasons: spring (such as March to May), summer (such as June to August), autumn (such as September to November), and winter (such as December to February). According to the time period, a day is divided into daytime (8:00 to 20:00) and night (such as 21:00 to 7:00).

[0141] A corresponding temperature change rate is set for each time period in each season, so there are a total of 8 preset temperature change rates for different time periods in different seasons. After obtaining the current time information, the heating device determines the preset temperature change rate by looking up the table based on the current season and time period. This is then determined as the temperature change rate that currently controls the operation of the heating device, as well as the corresponding operating time. Based on this operating time, the heating element of the heating device is controlled to operate, enabling the heating device to accurately control its internal temperature within the appropriate disinfection temperature range, ensuring the disinfection effect.

[0142] In some embodiments of the present invention, obtaining the temperature change rate of the heating device further includes: determining a preset heating rate as the heating rate and determining a preset cooling rate as the cooling rate when the ambient temperature and time information are not obtained.

[0143] In an embodiment of the present invention, if the heating device cannot obtain the actual ambient temperature or the current accurate time information, the preset heating rate and the preset cooling rate calibrated at the factory are directly used as the temperature change rate for controlling the operation of the heating device, thereby determining the operating time of the heating element. Among them, the preset heating rate and the preset cooling rate are obtained through experiments at the factory and can reflect the heating rate and the cooling rate of the heating device in most cases. Among them, the preset heating rate and the preset cooling rate can be the heating rate and the cooling rate measured experimentally when the ambient temperature is in the range of 24°C to 26°C.

[0144] In some embodiments of the present invention, the working time includes a first time and a second time, the first time indicates the time during which the heating element continues to work, and the second time indicates the time during which the heating element stops working.

[0145] In an embodiment of the present invention, the operating duration specifically includes a first duration for instructing the heating element to heat, and a second duration for instructing the heating element to stop heating. During operation of the heating device, the heating element is first controlled to continue heating for the first duration. After the operating duration of the heating element reaches the first duration, that is, after the temperature in the heating device reaches the upper limit of the target temperature range, the heating element is controlled to stop heating for the next second duration. At this time, the relay connected to the heating element can be controlled to disconnect.

[0146] After the time period after the heating element stops heating reaches the second time period, the control relay is turned on. At this time, the heating element continues to work again within the next first time period, and the cycle continues.

[0147] The embodiment of the present application determines the first duration of continuous operation of the heating element and the second duration of stopping operation of the heating element based on the temperature change rate, and controls the operation of the heating element of the heating device based on the first duration and the second duration, so that the internal temperature of the heating device can be accurately controlled within a suitable disinfection temperature range. On the one hand, it avoids excessively high temperatures and prevents the heating device from causing damage to the disinfected object. On the other hand, it can effectively ensure the disinfection temperature and avoid excessively low temperatures, thereby ensuring the disinfection effect.

[0148] In some embodiments of the present invention, the working duration of the heating element is determined based on the temperature change rate, including: determining a first target temperature and a second target temperature based on a start-up instruction, the first target temperature being greater than the second target temperature; determining a first duration based on the first target temperature, the ambient temperature and the heating rate; determining a second duration based on the first target temperature, the second target temperature and the cooling rate.

[0149] In the embodiment of the present invention, the first target temperature is the upper limit temperature of the target temperature range when the heating device is disinfected, and the second target temperature is the lower limit temperature of the target temperature range when the poison cabinet is disinfected.

[0150] When determining the first duration, that is, the duration during which the heating element continues to work, the first duration Tr is calculated based on the first target temperature Tg1, the obtained ambient temperature T and the calculated heating rate Vr.

[0151] It is understandable that when the ambient temperature cannot be obtained, calculation can be performed using a pre-stored preset temperature.

[0152] The specific calculation formula is as follows:

[0153] Tr=(Tg1-T)÷Vr;

[0154] Wherein, Tr is the first duration, Tg1 is the first target temperature, Vr is the heating rate, and T is the ambient temperature.

[0155] When determining the second duration, that is, the duration during which the heating element stops working, the second duration Td is calculated based on the first target temperature Tg1, the second target temperature Tg2 and the calculated cooling rate Vd.

[0156] The specific calculation formula is as follows:

[0157] Td=(Tg1–Tg2)÷Vd;

[0158] Wherein, Td is the second time duration, Tg1 is the first target temperature, Tg2 is the second target temperature, and Vd is the cooling rate.

[0159] In some embodiments of the present invention, obtaining the ambient temperature includes: sending a query instruction to a target device, where the query instruction is used to control the target device to send the ambient temperature to a heating device; and receiving the ambient temperature.

[0160] In an embodiment of the present invention, the target device may be a network server that stores binding relationships between the heating device and household appliances capable of obtaining ambient temperature information within the home environment in which the heating device is located. For example, the heating device sends a query command to the network server. Based on the query command, the network server requests the air conditioner in the home environment to proactively report the ambient temperature. After the air conditioner reports the ambient temperature, the server forwards the ambient temperature to the heating device. It is understood that if the air conditioner does not report the ambient temperature within a preset time, the network server may request the next household appliance, such as an air purifier, to report the ambient temperature.

[0161] The target device can also be other household appliances in the same IoT environment as the heating device, such as air conditioners. The heating device sends a query instruction to the air conditioner through the IoT. The air conditioner calls its own temperature detection module to obtain the ambient temperature based on the received query instruction and sends it to the heating device.

[0162] The target device can also be the user's mobile phone. The heating device sends a query instruction to the user's mobile phone APP (Application). The mobile phone APP can collect the ambient temperature based on its own sensors, or obtain the regional ambient temperature through the Internet, or obtain the ambient temperature through other home devices bound to the APP, and send it to the heating device.

[0163] The embodiment of the present application initiates a query to the target device and obtains the ambient temperature through the target device, so that the heating device does not need to be equipped with an independent temperature sensor, thereby optimizing the structure and cost of the heating device.

[0164] In some embodiments of the present invention, Figure 4 FIG4 shows a fourth flow chart of a method for controlling a heating device according to an embodiment of the present invention. Figure 4 As shown, the method includes:

[0165] Step 402, receiving a user's selection input;

[0166] Step 404, starting the disinfection function according to user input;

[0167] Step 406, determine whether the device is connected to the network; if yes, proceed to step 408, otherwise proceed to step 410;

[0168] Step 408, obtaining the indoor temperature;

[0169] Step 410, controlling heating according to a default working time;

[0170] Step 412, determine whether the indoor temperature is obtained; if yes, proceed to step 414, otherwise proceed to step 418;

[0171] Step 414, calculating the heating rate according to the indoor temperature;

[0172] Step 416, calculating the cooling rate according to the indoor temperature;

[0173] Step 418, determine whether the time information is obtained; if yes, proceed to step 420, otherwise proceed to step 424;

[0174] Step 420, determining the season and time period based on the time information;

[0175] Step 422, determine the heating rate and cooling rate by looking up a table according to the season and time period;

[0176] Step 424, obtaining a preset heating rate and cooling rate;

[0177] Step 426, calculating the heating time according to the heating rate;

[0178] Step 428, calculating the cooling time for stopping heating according to the cooling rate;

[0179] Step 430: Control heating according to the heating time and the cooling time.

[0180] In an embodiment of the present invention, the heating device is connected to the Internet of Things via Wi-Fi, etc., and by obtaining indoor temperature information from a mobile phone or other household appliances, the temperature rise and fall rates are intelligently adjusted, thereby more accurately controlling the temperature of the heating device.

[0181] Specifically, the test measures the heating device's temperature rise and fall rates at different temperatures, generating relevant data. This data can be stored locally, in an app, or in the cloud. If stored in the app or cloud, it will be proactively sent to the device when it connects to the network.

[0182] When the user selects the function of the heating device, the temperature data is first obtained from the APP, and then the temperature rate table is queried based on the temperature data to obtain the temperature rise rate Vr and the temperature drop rate Vd. Finally, the heating time and the heating stop time are calculated based on this rate, and the related loads are controlled to start and stop.

[0183] When the device is not connected to the Internet, it runs at the default Vr1 and Vd1 (which can be the parameters at 24 degrees Celsius indoors).

[0184] When the device is connected to the Internet but cannot obtain the temperature, it will obtain the season (spring, summer, autumn, winter) and whether it is daytime (8:00-20:00) or night based on the network system time, and then select the corresponding default rate parameters, that is, the 8 default parameters stored locally.

[0185] Example 2

[0186] In some embodiments of the present invention, a control device for a heating device is provided, wherein the heating device includes a heating element, Figure 5 FIG. 4 shows a structural block diagram of a control device for a heating device according to an embodiment of the present invention. Figure 5 As shown, the control device 500 of the heating device includes:

[0187] The acquisition module 502 is used to obtain the temperature change rate of the heating device in response to the start instruction; the determination module 504 is used to determine the working time of the heating element according to the temperature change rate; the control module 506 is used to control the operation of the heating element according to the working time.

[0188] In an embodiment of the present invention, the heating device includes a heating element, which can be an electric heating element or a hot air component. By controlling the heating element to be powered on and heated to generate high temperature, the high temperature is used to kill microorganisms such as bacteria and viruses, thereby achieving sterilization and disinfection. Specifically, during the operation of the heating device, after receiving a start-up instruction, the heating element is controlled to be powered on, wherein a relay can be set between the heating element and the power supply. When the heating element is required to work, the relay is closed, the heating element is connected to the power supply, and the power supply provides electrical energy to the heating element, thereby controlling the operation of the heating element. When the heating element is required to stop working, the relay is disconnected, the heating element is disconnected from the power supply, and heating stops.

[0189] Generally speaking, when using a heating device for disinfection, in order to ensure the disinfection effect, it is also necessary to prevent high temperatures from damaging the objects being disinfected, such as plastic tableware and glassware. Therefore, the temperature inside the heating device needs to be maintained within a suitable range. Low-cost heating devices do not have a dedicated temperature control module, so the temperature cannot be maintained by adjusting the heating power of the heating element. Instead, the operating time of the heating element must be adjusted to maintain the temperature within a certain range.

[0190] For example, the target disinfection temperature range of the heating device is A℃ to B℃, and A>B. Then the heating element of the heating device can be controlled to continue heating within X minutes to increase the temperature inside the heating device to A℃. After that, the heating element of the heating device can be controlled to stop heating within Y minutes to slowly drop the temperature of the heating device to B degrees Celsius.

[0191] Among them, the heating power of the heating element is fixed, and the temperature change in the heating device will vary with the environment. Therefore, the temperature change caused by the same heating time may be different. In this regard, after receiving the start instruction, the embodiment of the present application first obtains the temperature change rate corresponding to the heating device. The temperature change rate indicates the rate of increase or decrease of the temperature in the heating device when the heating element of the heating device is working or not working under the current environment of the heating device. In other words, based on the temperature change rate, it is possible to determine the time required for the heating device to raise the internal temperature to the upper limit of the target temperature range, the working time required for the heating element, and the time it takes for the internal temperature of the heating device to naturally drop to the lower limit of the target temperature range after the heating element stops working.

[0192] Therefore, the working time of the heating element is determined according to the temperature change rate, and the heating element of the heating device is controlled to work based on the working time, so that the internal temperature of the heating device can be accurately controlled within the appropriate disinfection temperature range. On the one hand, it avoids excessively high temperature and prevents the heating device from causing damage to the object being disinfected. On the other hand, it can effectively ensure the disinfection temperature and avoid excessively low temperature, thereby ensuring the disinfection effect.

[0193] The embodiment of the present application determines the target working time of the heating element of the heating device according to the temperature change rate corresponding to the current environment of the heating device, and controls the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

[0194] In some embodiments of the present invention, the image acquisition module is further used to acquire the ambient temperature; and the determination module is further used to determine the temperature change rate according to the ambient temperature.

[0195] In the embodiments of the present invention, the temperature change rate within the heating device specifically includes the heating rate of the heating device and the cooling rate of the heating device. When the heating device heats up, the heating element operates and releases heat, causing the temperature within the heating device to rise. During this process, before the heating element operates, the temperature within the heating device is close to the ambient temperature. When the heating power of the heating element is fixed, the lower the ambient temperature, the slower the heating rate. Therefore, the heating rate is affected by the ambient temperature.

[0196] At the same time, when the heating device stops heating and cools down, because the temperature inside the heating device is higher than the ambient temperature, the heat inside the heating device will gradually dissipate into the environment, causing the temperature inside the heating device to naturally drop. During this process, the lower the ambient temperature, the greater the temperature difference between the heating device and the ambient temperature, and therefore the faster the temperature drop. Therefore, the cooling rate is also affected by the ambient temperature.

[0197] It can be seen that the heating rate and cooling rate of the heating equipment are both related to the ambient temperature. Therefore, by collecting the ambient temperature and determining the heating rate and cooling rate of the heating equipment according to the ambient temperature, the actual temperature change rate of the heating equipment under the current environmental conditions can be accurately reflected, thereby determining the working time of the heating element according to the temperature change rate, and accurately controlling the internal temperature of the heating equipment so that the internal temperature is controlled within the appropriate disinfection temperature range, avoiding excessively high temperature, and preventing the heating equipment from causing damage to the object being disinfected. At the same time, it can effectively ensure the disinfection temperature and ensure the disinfection effect.

[0198] It is understood that in some embodiments, the heating device can collect ambient temperature information using its own ambient temperature sensor. In other embodiments, the heating device can obtain ambient temperature information collected by other smart home devices through the Internet of Things, such as air conditioners, air purifiers, and fresh air blowers. This eliminates the need for a separate temperature sensor for the heating device, optimizing the structure and cost of the heating device.

[0199] In some embodiments of the present invention, the acquisition module is also used to obtain the preset heating rate, the preset cooling rate, the heating coefficient and the cooling coefficient; the determination module is also used to determine the heating rate based on the ambient temperature, the preset heating rate and the heating coefficient; and to determine the cooling rate based on the ambient temperature, the preset cooling rate and the cooling coefficient.

[0200] In the embodiment of the present invention, when determining the temperature change rate, the temperature rise coefficient of the heating device and the temperature drop coefficient of the heating device may be determined respectively according to the current ambient temperature.

[0201] Specifically, first, obtain the preset heating rate and preset cooling rate of the heating device, and obtain the heating coefficient and cooling coefficient of the heating device. The preset heating rate and preset cooling rate are obtained through experiments at the factory and can reflect the heating rate and cooling rate of the heating device in most cases. The preset heating rate and preset cooling rate can be the heating rate and cooling rate experimentally measured when the ambient temperature is within the range of 24°C to 26°C.

[0202] The temperature rise coefficient specifically reflects the heating capacity of a heating element in a heating device. The greater the heating power of the heating element, the greater the heating capacity and the larger the temperature rise coefficient. This coefficient is related to the model, parameters, and power of the heating element. Therefore, once the heating element is selected, the temperature rise coefficient of the heating device is fixed. Therefore, this coefficient can be preset in the heating device controller during production.

[0203] The cooling coefficient specifically reflects the thermal insulation capacity of the cabinet of the heating equipment. The better the thermal insulation capacity of the cabinet, the less likely the heat in the heating equipment is to dissipate outside the cabinet, and the lower the cooling coefficient.

[0204] According to the actual ambient temperature of the environment in which the heating device is currently located, the pre-stored preset heating rate, and the pre-stored heating coefficient, the heating rate of the heating device in the current environment can be accurately calculated.

[0205] At the same time, based on the actual ambient temperature of the environment in which the heating device is currently located, the pre-stored preset cooling rate, and the pre-stored cooling coefficient, the cooling rate of the heating device in the current environment can be accurately calculated.

[0206] The embodiment of the present application accurately calculates the heating rate and cooling rate of the heating device to obtain the temperature change rate corresponding to the current environment of the heating device, so as to determine the target working time of the heating element of the heating device, and controls the operation of the heating element based on the working time, thereby achieving precise control of the disinfection temperature of the heating device and improving the disinfection effect of the heating device.

[0207] In some embodiments of the present invention, the determination module is further configured to calculate the heating rate using the following formula:

[0208] Vr=Vr1+(T-26)×Kr;

[0209] Wherein, Vr is the heating rate, Vr1 is the preset heating rate, T is the ambient temperature, and Kr is the heating coefficient.

[0210] In an embodiment of the present invention, taking 26°C as the reference temperature, the difference between the current ambient temperature T and the reference temperature is first calculated, and then the product of the difference and the temperature rise coefficient is calculated to obtain the difference between the heating rate at the current room temperature and the preset heating rate at the reference temperature, and the preset heating rate at the reference temperature is compensated accordingly, thereby obtaining the accurate heating rate of the heating device at the current ambient temperature. The heating working time of the heating element is determined by the heating rate, and the heating element of the heating device is controlled to work based on the working time, which can enable the heating device to accurately control its internal temperature within the appropriate disinfection temperature range to ensure the disinfection effect.

[0211] In some embodiments of the present invention, the determination module is further configured to calculate the cooling rate using the following formula:

[0212] Vd=Vd1+(26-T)×Kd;

[0213] Wherein, Vd is the cooling rate, Vd1 is the preset cooling rate, T is the ambient temperature, and Kd is the cooling coefficient.

[0214] In an embodiment of the present invention, taking 26°C as the reference temperature, the difference between the current ambient temperature T and the reference temperature is first calculated, and then the product of the difference and the cooling coefficient is calculated to obtain the difference between the cooling rate at the current room temperature and the preset cooling rate at the reference temperature, and the preset cooling rate at the reference temperature is compensated accordingly, thereby obtaining the accurate cooling rate of the heating device at the current ambient temperature. The working time of the heating element when it stops heating is determined by the cooling rate, and the heating element of the heating device is controlled to work based on the working time, so that the internal temperature of the heating device can be accurately controlled within the appropriate disinfection temperature range to ensure the disinfection effect.

[0215] In some embodiments of the present invention, the acquisition module is further configured to acquire time information when the ambient temperature is not acquired; and the determination module is further configured to determine the temperature change rate based on the time information.

[0216] In an embodiment of the present invention, if the current heating device cannot obtain the actual ambient temperature, such as no temperature sensor is set on the heating device, or the network module of the heating device cannot be connected to the Internet normally, or there is no smart home device that can obtain the ambient temperature in the network environment or the Internet of Things where the heating device is located, the corresponding temperature change rate can be determined by time information.

[0217] Specifically, the time information includes season information and time period information. The format of the time information can be the "year-month-day" time format. The control device of the heating device can have a built-in time module, and an initial time is set at the factory. The time module automatically counts and records the current time information.

[0218] In other embodiments, the heating device can access a time server via a wireless network to obtain more accurate time information. The time server can be a network server, a gateway, a user's mobile phone, or other smart home device, which is not limited in this application.

[0219] Since the ambient temperature is different in different seasons and time periods, the corresponding temperature change rate will also be different. In the embodiment of the present application, different temperature change rates are preset for different seasons and time periods.

[0220] For example, according to the season, a year is divided into four seasons: spring (such as March to May), summer (such as June to August), autumn (such as September to November), and winter (such as December to February). According to the time period, a day is divided into daytime (8:00 to 20:00) and night (such as 21:00 to 7:00).

[0221] A corresponding temperature change rate is set for each time period in each season, so there are a total of 8 preset temperature change rates for different time periods in different seasons. After obtaining the current time information, the heating device determines the preset temperature change rate by looking up the table based on the current season and time period. This is then determined as the temperature change rate that currently controls the operation of the heating device, as well as the corresponding operating time. Based on this operating time, the heating element of the heating device is controlled to operate, enabling the heating device to accurately control its internal temperature within the appropriate disinfection temperature range, ensuring the disinfection effect.

[0222] In some embodiments of the present invention, the determination module is further configured to determine the preset heating rate as the heating rate and the preset cooling rate as the cooling rate when the ambient temperature and time information are not obtained.

[0223] In an embodiment of the present invention, if the heating device cannot obtain the actual ambient temperature or the current accurate time information, the preset heating rate and the preset cooling rate calibrated at the factory are directly used as the temperature change rate for controlling the operation of the heating device, thereby determining the operating time of the heating element. Among them, the preset heating rate and the preset cooling rate are obtained through experiments at the factory and can reflect the heating rate and the cooling rate of the heating device in most cases. Among them, the preset heating rate and the preset cooling rate can be the heating rate and the cooling rate measured experimentally when the ambient temperature is in the range of 24°C to 26°C.

[0224] In some embodiments of the present invention, the working time includes a first time and a second time, the first time indicates the time during which the heating element continues to work, and the second time indicates the time during which the heating element stops working.

[0225] In an embodiment of the present invention, the operating duration specifically includes a first duration for instructing the heating element to heat, and a second duration for instructing the heating element to stop heating. During operation of the heating device, the heating element is first controlled to continue heating for the first duration. After the operating duration of the heating element reaches the first duration, that is, after the temperature in the heating device reaches the upper limit of the target temperature range, the heating element is controlled to stop heating for the next second duration. At this time, the relay connected to the heating element can be controlled to disconnect.

[0226] After the time period after the heating element stops heating reaches the second time period, the control relay is turned on. At this time, the heating element continues to work again within the next first time period, and the cycle continues.

[0227] The embodiment of the present application determines the first duration of continuous operation of the heating element and the second duration of stopping operation of the heating element based on the temperature change rate, and controls the operation of the heating element of the heating device based on the first duration and the second duration, so that the internal temperature of the heating device can be accurately controlled within a suitable disinfection temperature range. On the one hand, it avoids excessively high temperatures and prevents the heating device from causing damage to the disinfected object. On the other hand, it can effectively ensure the disinfection temperature and avoid excessively low temperatures, thereby ensuring the disinfection effect.

[0228] In some embodiments of the present invention, the determination module is also used to determine the first target temperature and the second target temperature according to the start-up instruction, the first target temperature being greater than the second target temperature; determine the first duration according to the first target temperature, the ambient temperature and the heating rate; and determine the second duration according to the first target temperature, the second target temperature and the cooling rate.

[0229] In the embodiment of the present invention, the first target temperature is the upper limit temperature of the target temperature range when the heating device is disinfected, and the second target temperature is the lower limit temperature of the target temperature range when the poison cabinet is disinfected.

[0230] When determining the first duration, that is, the duration during which the heating element continues to work, the first duration Tr is calculated based on the first target temperature Tg1, the obtained ambient temperature T and the calculated heating rate Vr.

[0231] It is understandable that when the ambient temperature cannot be obtained, calculation can be performed using a pre-stored preset temperature.

[0232] The specific calculation formula is as follows:

[0233] Tr=(Tg1-T)÷Vr;

[0234] Wherein, Tr is the first duration, Tg1 is the first target temperature, Vr is the heating rate, and T is the ambient temperature.

[0235] When determining the second duration, that is, the duration during which the heating element stops working, the second duration Td is calculated based on the first target temperature Tg1, the second target temperature Tg2 and the calculated cooling rate Vd.

[0236] The specific calculation formula is as follows:

[0237] Td=(Tg1–Tg2)÷Vd;

[0238] Wherein, Td is the second time duration, Tg1 is the first target temperature, Tg2 is the second target temperature, and Vd is the cooling rate.

[0239] In some embodiments of the present invention, the control device further includes: a sending module for sending a query instruction to the target device, the query instruction being used to control the target device to send the ambient temperature to the heating device; and a receiving module for receiving the ambient temperature.

[0240] In an embodiment of the present invention, the target device may be a network server that stores binding relationships between the heating device and household appliances capable of obtaining ambient temperature information within the home environment in which the heating device is located. For example, the heating device sends a query command to the network server. Based on the query command, the network server requests the air conditioner in the home environment to proactively report the ambient temperature. After the air conditioner reports the ambient temperature, the server forwards the ambient temperature to the heating device. It is understood that if the air conditioner does not report the ambient temperature within a preset time, the network server may request the next household appliance, such as an air purifier, to report the ambient temperature.

[0241] The target device can also be other household appliances in the same IoT environment as the heating device, such as air conditioners. The heating device sends a query instruction to the air conditioner through the IoT. The air conditioner calls its own temperature detection module to obtain the ambient temperature based on the received query instruction and sends it to the heating device.

[0242] The target device can also be the user's mobile phone. The heating device sends a query instruction to the user's mobile phone APP (Application). The mobile phone APP can collect the ambient temperature based on its own sensors, or obtain the regional ambient temperature through the Internet, or obtain the ambient temperature through other home devices bound to the APP, and send it to the heating device.

[0243] The embodiment of the present application initiates a query to the target device and obtains the ambient temperature through the target device, so that the heating device does not need to be equipped with an independent temperature sensor, thereby optimizing the structure and cost of the heating device.
