[0002] As people's living standards improve, the use of air conditioners is becoming more and more popular. At present, ordinary air conditioners can adjust the air temperature and humidity to keep the indoor temperature and humidity environment within a comfortable range. In order to solve the problem of insufficient heating capacity of air conditioners, air conditioners are usually equipped with electric heating devices for auxiliary heating. When the air conditioner is running in cooling mode, due to the high humidity of the air, condensation will occur inside the air conditioner, and condensation will also accumulate on the electric heating device, posing a hidden danger of condensation dripping. Moreover, the electric heating devices of existing air conditioners are generally of a single power type. When the cooling is turned on, due to the interaction between cold and hot and the large amount of heat, the accumulation of condensation on the electric heating device will cause large cold and hot shock deformation and water vapor.

[0042] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified and limited, the terms "first" and "second" are used to clearly illustrate the numbering of product components and do not represent any substantial difference. "Up," "down," "left," "right," etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0044] It should be noted that, unless otherwise specified or limited, the term "connected" should be understood in a broad sense, for example, it can mean directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present invention can be understood by those skilled in the art in specific circumstances.

[0045] Figure 1 FIG. 1 is a flow chart of an air conditioning anti-condensation control method according to an embodiment of the present invention. Figure 1 As shown, the air conditioning anti-condensation control method provided by the present invention includes the following steps:

[0046] Step S10, determining that the air conditioner is operating in a cooling mode and the cooling operation time is greater than a first time period;

[0047] Step S20, obtaining the air conditioner operating frequency;

[0048] Step S30 , when the air conditioner operating frequency is less than or equal to the preset frequency, the operating state and operating mode of the PTC heating device are controlled according to the temperature difference between the indoor ambient temperature and the set temperature.

[0049] In this embodiment, an air conditioner is installed to regulate the indoor air environment. The air conditioner includes a compressor, a condenser and an evaporator. The compressor compresses the gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser (outdoor unit) to dissipate heat and become a liquid refrigerant at room temperature and high pressure; the liquid refrigerant enters the evaporator (indoor unit) through an expansion valve or a capillary tube (throttling component), the space suddenly increases, the pressure decreases, the liquid refrigerant vaporizes and becomes a gaseous low-temperature refrigerant, absorbing a large amount of heat in the air, the evaporator will become cold, and the air will blow through the evaporator, so that the indoor unit blows out cold air to achieve indoor cooling; the water vapor in the air will condense into water droplets after encountering the cold evaporator, forming condensation water.

[0050] Among them, when the air conditioner is running in cooling mode, the air conditioner operating frequency self-adjusts according to the changes in indoor temperature. The compressor runs at a non-fixed frequency and quickly reaches the set temperature at a high speed when the air conditioner is turned on. After that, the compressor changes to a low and slow speed to maintain the temperature, ensuring that the indoor temperature will not fluctuate between hot and cold, ensuring the user's physical comfort, while saving energy and reducing consumption. In addition, a preset frequency is pre-set, and the preset frequency is used to determine the high and low frequency of the air conditioner operation. When the air conditioner operating frequency is greater than the preset frequency, the air conditioner operating frequency is determined to be high; when the air conditioner operating frequency is less than or equal to the preset frequency, the air conditioner operating frequency is determined to be low. For example, if the preset frequency is set to 30Hz, then the air conditioner operating frequency is determined to be low when it is less than or equal to 30Hz.

[0051] When the air conditioner operates at a low frequency, it may be running at a low wind speed. In order to prevent condensation, frequency limitation will be implemented during low wind speed operation. Therefore, low-frequency operation is one of the conditions for determining a low wind speed. The air conditioner may also operate at a low frequency after the indoor ambient temperature reaches the set temperature. This is different from the low wind speed operation.

[0052] Air conditioners also include PTC (Positive Temperature Coefficient) heaters. These devices use PTC elements for electrical heating. PTC elements have a low resistance at room temperature and can generate heat when powered. When the temperature reaches near the Curie temperature, the PTC element's resistance increases rapidly within a narrow temperature range, approaching that of an insulator. This makes PTC elements self-regulating, flame-free, and non-flammable, eliminating potential safety hazards. They also offer high heating efficiency and high power. PTC elements can be considered constant-temperature heaters, with their operating temperature roughly constant at their Curie temperature. When the air conditioner is in cooling mode, the air temperature drops, cooling the PTC heater. Water vapor in the air condenses upon contact with the cold PTC heater, forming condensation. At this point, the PTC heater is controlled to be on and powered on, raising its temperature and preventing condensation. It also reduces relative humidity through heating, thus preventing condensation.

[0053] The PTC heating device has a first operating mode and a second operating mode, and the operating temperature of the PTC heating device in the first operating mode is greater than the operating temperature in the second operating mode. In the first operating mode, the operating temperature of the PTC heating device is the first operating temperature, that is, the PTC heating device generates heat at the first operating temperature; in the second operating mode, the operating temperature of the PTC heating device is the second operating temperature, that is, the PTC heating device generates heat at the second operating temperature; the first operating temperature is greater than the second operating temperature.

[0054] Specifically, in this embodiment, when the air conditioner is turned on, the air conditioner's operating mode is first determined. Once the air conditioner is determined to be operating in cooling mode, the cooling operation duration to be continued after cooling is turned on is determined. If the air conditioner is determined to be operating in cooling mode and the cooling operation duration is greater than a first duration, for example, 30 minutes, after 30 minutes of cooling operation, the indoor temperature changes, and the air conditioner operating frequency also changes accordingly according to the cooling mode setting program. Thereafter, the air conditioner operating frequency is obtained and compared with a preset frequency. If the air conditioner's operating frequency is less than or equal to the preset frequency, it indicates a low operating frequency. The air conditioner may be operating at a low fan speed or at a low frequency after reaching the set temperature. At this time, the operating state and operating mode of the PTC heater are further controlled based on the temperature difference between the indoor ambient temperature and the set temperature. The temperature difference between the indoor ambient temperature and the set temperature can reflect the indoor temperature fluctuations and determine the cooling and condensation prevention requirements. The operating state of the PTC heater is controlled and the operating mode of the PTC heater is selected based on the cooling and condensation prevention requirements. The PTC heater can be activated and heated in a timely manner based on the cooling and condensation prevention requirements to increase the temperature of the PTC heater and prevent condensation from forming on the PTC heater. This can reduce the indoor relative humidity through heating, thereby effectively preventing condensation. Furthermore, the PTC heater has different heating temperatures in different operating modes. Selecting the operating mode of the PTC heater based on the cooling and condensation prevention requirements has a minimal impact on the user's cooling capacity, reducing power consumption and achieving energy savings while ensuring user comfort.

[0055] The air conditioner anti-condensation control method of the present invention obtains the air conditioner operating frequency after the cooling is turned on for a first period of time. When the air conditioner operating frequency is low, the working state and working mode of the PTC heater are controlled according to the temperature difference between the indoor ambient temperature and the set temperature. The PTC heater can be turned on in time to operate and generate heat according to the cooling and anti-condensation requirements to increase the temperature of the PTC heater and prevent condensation from forming on the PTC heater. It can also reduce the indoor relative humidity by heating, thereby effectively achieving the anti-condensation effect. At the same time, the PTC heater has different heating temperatures in different working modes. The working mode of the PTC heater is selected according to the cooling and anti-condensation requirements, which has little impact on the user's cooling capacity. On the premise of ensuring the user's physical comfort, it reduces power consumption, saves energy and reduces consumption, and effectively solves the defects in the prior art that condensation will accumulate on the electric heater in the air conditioner cooling mode, there is a hidden danger of condensation dripping, and the cold and hot shock deformation and water vapor caused by the turning on of the electric heater at this time are large, which affect the user experience and the service life of the electric heater.

[0056] Specifically, in the first operating mode, the operating temperature of the PTC heating device is greater than the first temperature, i.e., the first operating temperature is greater than the first temperature. In the second operating mode, the operating temperature of the PTC heating device is less than the second temperature, i.e., the second operating temperature is less than the second temperature, and the second temperature is less than the first temperature. For example, the first temperature of 200°C is suitable for high-power, rapid heating of the air conditioner; the second temperature of 150°C is suitable for low-power heating of the air conditioner.

[0057] Specifically, if Figures 2 to 6 As shown, the PTC heating device includes a first conductive member 1, at least two second conductive members 2 and at least two PTC heating layers 3, the first conductive member 1 is arranged between the at least two second conductive members 2, each PTC heating layer 3 is arranged between the first conductive member 1 and one second conductive member 2, and both sides of the PTC heating layer 3 are in conductive contact with the first conductive member 1 and the second conductive member 2 respectively; wherein, the PTC heating layer 3 includes a first PTC heating layer and a second PTC heating layer, the first PTC heating layer has a first operating temperature, the second PTC heating layer has a second operating temperature, and the first operating temperature is greater than the second operating temperature. The operation of the PTC heating device in the first operating mode includes: controlling the first conductive member 1 and the second conductive member 2 on both sides of the first PTC heating layer to be energized. The operation of the PTC heating device in the second operating mode includes: controlling the first conductive member 1 and the second conductive member 2 on both sides of the second PTC heating layer to be energized.

[0058] In this embodiment, the first conductive member 1 is disposed between at least two second conductive members 2, such that the at least two second conductive members 2 can each be disposed opposite a portion of the first conductive member 1, thereby forming an installation space between the second conductive member 2 and the portion of the first conductive member 1 opposite the second conductive member 2. Thus, the at least two second conductive members 2 and the first conductive member 1 can form at least two installation spaces. One of the first conductive member 1 and the second conductive member 2 is used to connect to the neutral wire, and the other is used to connect to the live wire. That is, when the first conductive member 1 is connected to the neutral wire, the at least two second conductive members 2 are each connected to the live wire; when the first conductive member 1 is connected to the live wire, the at least two second conductive members 2 are each connected to the neutral wire.

[0059] Each PTC heating layer 3 is disposed between a second conductive element 2 and a first conductive element 1. That is, the number of PTC heating layers 3 is the same as the number of second conductive elements 2. The PTC heating layers 3 are installed within the aforementioned installation space, with both sides of the PTC heating layer 3 in conductive contact with the second conductive element 2 and the first conductive element 1, respectively, forming a laminated heating element. At least two PTC heating layers 3, the first conductive element 1, and at least two second conductive elements 2 form at least two heating elements. When any second conductive element 2 is electrically connected to the first conductive element 1, the PTC heating layer 3 located between the second conductive element 2 and the first conductive element 1 is energized and generates heat.

[0060] The at least two PTC heating layers 3 include a first PTC heating layer and a second PTC heating layer, and the first PTC heating layer and the second PTC heating layer each include a different type of PTC heating sheet 31. By using different types of PTC heating sheets 31, the first PTC heating layer has a first operating temperature, the second PTC heating layer has a second operating temperature, and the first operating temperature is greater than the second operating temperature.

[0061] When the first conductive member 1 and the second conductive member 2 on both sides of the first PTC heating layer are controlled to be energized, the first PTC heating layer is energized and generates heat, so that the PTC heating device generates heat at the first operating temperature. At this time, the PTC heating device operates in the first operating mode.

[0062] When the first conductive member 1 and the second conductive member 2 on both sides of the second PTC heating layer are controlled to be energized, the second PTC heating layer is energized and generates heat, so that the PTC heating device generates heat at the second operating temperature. At this time, the PTC heating device operates in the second operating mode.

[0063] The PTC heating device of this embodiment realizes the selective control of the first working mode and the second working mode of the PTC heating device by controlling the first PTC heating layer to be powered on and heated or the second PTC heating layer to be powered on and heated as needed, thereby meeting the application requirements of different scenarios. In addition, at least two PTC heating layers 3 form a multi-layer heating body with a stacked structure with the first conductive member 1 and at least two second conductive members 2. The structure is compact, saves space, increases power density, improves usage effect, and enhances user comfort.

[0064] In a specific embodiment, Figure 4 As shown, the PTC heating device includes a first conductive member 1 and two second conductive members 2, and the first conductive member 1 and the second conductive member 2 are both conductive strips; the first PTC heating layer is a conventional high-temperature PTC heating sheet layer, and the normal operating temperature can reach above 200°C. When the conductive strips on both sides of the high-temperature PTC heating sheet layer are energized, the PTC heating device is in the first working mode and is used for high-power and rapid heating of the air conditioner; the second PTC heating layer is a conventional low-temperature PTC sheet layer, and the normal operating temperature is below 150°C. It is used for low-power heating of the air conditioner. When the conductive strips on both sides of the low-temperature PTC heating sheet layer are energized, the PTC heating device is in the second working mode.

[0065] Specifically, when the air conditioner operating frequency is less than or equal to the preset frequency, the operating state and operating mode of the PTC heating device are controlled according to the temperature difference between the indoor ambient temperature and the set temperature, including the following steps:

[0066] Step S301, obtaining the indoor ambient temperature;

[0067] Step S302: When the temperature difference between the indoor ambient temperature and the set temperature is greater than or equal to the first temperature difference and less than or equal to the second temperature difference, the PTC heating device is controlled to turn on and operate in the first working mode.

[0068] In this embodiment, the set temperature can be set by the user by obtaining the indoor ambient temperature and presetting a first temperature difference and a second temperature difference. The first temperature difference and the second temperature difference are used to determine whether the temperature difference between the indoor ambient temperature and the set temperature is within the preset temperature difference range. When the temperature difference between the indoor ambient temperature and the set temperature is less than the first temperature difference, the temperature difference between the indoor ambient temperature and the set temperature is determined to be less than the preset temperature difference range. When the temperature difference between the indoor ambient temperature and the set temperature is greater than or equal to the first temperature difference and less than or equal to the second temperature difference, the temperature difference between the indoor ambient temperature and the set temperature is determined to be within the preset temperature difference range. When the temperature difference between the indoor ambient temperature and the set temperature is greater than the second temperature difference, the temperature difference between the indoor ambient temperature and the set temperature is determined to be greater than the preset temperature difference range. For example, if the first temperature difference is set to 0.5°C and the second temperature difference is set to 2°C, the temperature difference between the indoor ambient temperature and the set temperature is determined to be within the preset temperature difference range if it is between 0.5°C and 2°C; and the temperature difference between the indoor ambient temperature and the set temperature is determined to be greater than the preset temperature difference range if it is greater than 2°C.

[0069] Specifically, in this embodiment, the indoor ambient temperature is first obtained; then, the temperature difference between the indoor ambient temperature and the set temperature is calculated, and the temperature difference between the indoor ambient temperature and the set temperature is compared with the first temperature difference and the second temperature difference. When the temperature difference between the indoor ambient temperature and the set temperature is greater than or equal to the first temperature difference and less than or equal to the second temperature difference, it means that the temperature difference between the indoor ambient temperature and the set temperature is within the preset temperature difference range, that is, the indoor ambient temperature has dropped to a limited extent and has not yet reached the set temperature, but the temperature difference between the indoor ambient temperature and the set temperature is not too large, the cooling has produced a certain effect, and there is a need to prevent condensation. At this time, the PTC heating device is controlled to turn on and operate in the first working mode. The PTC heating device generates heat at the higher first working temperature, has a large power, can quickly heat and heat, increase the temperature of the PTC heating device, prevent condensation from forming on the PTC heating device when it is cold, and can simultaneously reduce the indoor humidity by heating, thereby effectively achieving an anti-condensation effect.

[0070] Specifically, controlling the PTC heating device to turn on and operate in the first operating mode specifically includes: controlling the PTC heating device to operate in the first operating mode for a second time period.

[0071] In this embodiment, based on the need for condensation prevention, the PTC heating device is controlled to operate continuously in the first operating mode for a second duration (for example, 10 minutes). This allows the PTC heating device to effectively raise its own temperature and prevent the formation of condensation. Furthermore, the PTC heating device continuously dehumidifies the air through heating for the second duration, effectively reducing air humidity and achieving a better condensation prevention effect. Furthermore, after the PTC heating device operates continuously in the first operating mode for the second duration to ensure the condensation prevention effect is achieved, the PTC heating device can be controlled to shut down, preventing excessive heating from affecting the user's cooling capacity. This ensures user comfort while reducing power consumption and achieving energy savings.

[0072] More specifically, if the difference between the indoor ambient temperature and the set temperature is determined to be greater than or equal to a first temperature difference and less than or equal to a second temperature difference, the PTC heater is controlled to activate and operate in the first operating mode after a fourth delay (for example, 5 minutes). By controlling the PTC heater to activate heating after continuing cooling for the fourth time, the cooling capacity loss caused by condensation prevention and dehumidification in the heating mode can be compensated, ensuring user comfort.

[0073] Furthermore, when the operating frequency of the air conditioner is less than or equal to the preset frequency, the operating state and operating mode of the PTC heating device are controlled according to the temperature difference between the indoor ambient temperature and the set temperature, and the following steps are also included:

[0074] Step S303: When the temperature difference between the indoor ambient temperature and the set temperature is greater than the second temperature difference, the PTC heating device is controlled to turn on and operate in the second working mode.

[0075] In this embodiment, after obtaining the indoor ambient temperature, the temperature difference between the indoor ambient temperature and the set temperature is calculated, and the temperature difference between the indoor ambient temperature and the set temperature is compared with the first temperature difference and the second temperature difference. When the temperature difference between the indoor ambient temperature and the set temperature is greater than the second temperature difference, it means that the temperature difference between the indoor ambient temperature and the set temperature is greater than the preset temperature difference range, that is, the temperature difference between the indoor ambient temperature and the set temperature is large, the indoor ambient temperature is limited to decrease, or the cooling set temperature is low and is far from reaching the set temperature, and it is necessary to meet both cooling and anti-condensation requirements. At this time, the PTC heating device is controlled to operate in the second working mode, and the PTC heating device generates heat at the lower second working temperature, thereby increasing the temperature of the PTC heating device to prevent condensation from forming on the PTC heating device when it is cold. In addition, the indoor humidity can be reduced by heating, effectively achieving an anti-condensation effect. In addition, the power of the PTC heating device is low, which has little impact on the user's cooling capacity, ensuring the user's physical comfort while reducing power consumption and saving energy.

[0076] Specifically, controlling the PTC heating device to turn on and operate in the second operating mode specifically includes: controlling the PTC heating device to operate in the second operating mode for a third time period.

[0077] In this embodiment, based on the need for condensation prevention, the PTC heating device is controlled to operate in the second operating mode for a third duration (for example, 15 minutes). This effectively raises the PTC heating device's temperature to prevent condensation. Furthermore, the PTC heating device continuously dehumidifies the air through heating for the third duration, effectively reducing humidity and achieving a more effective condensation prevention effect. Furthermore, after the PTC heating device operates in the second operating mode for the third duration to ensure the desired condensation prevention effect, it can be controlled to shut down. This prevents excessive heating from impacting the user's cooling capacity, ensuring user comfort while reducing power consumption and achieving energy savings.

[0078] More specifically, if the difference between the indoor ambient temperature and the set temperature is greater than a second temperature difference, the PTC heater is controlled to activate and operate in the second operating mode after a fifth delay (e.g., 8 minutes). By controlling the PTC heater to activate heating after continuing cooling for the fifth time, the cooling capacity loss caused by condensation prevention and dehumidification in the heating mode can be compensated, ensuring user comfort.

[0079] Furthermore, when the operating frequency of the air conditioner is less than or equal to the preset frequency, the operating state and operating mode of the PTC heating device are controlled according to the temperature difference between the indoor ambient temperature and the set temperature, and the following steps are also included:

[0080] Step S304: When the temperature difference between the indoor ambient temperature and the set temperature is less than the first temperature difference, the PTC heating device is controlled to be in an off state.

[0081] In this embodiment, after obtaining the indoor ambient temperature, the temperature difference between the indoor ambient temperature and the set temperature is calculated, and the temperature difference between the indoor ambient temperature and the set temperature is compared with the first temperature difference and the second temperature difference. If the temperature difference between the indoor ambient temperature and the set temperature is less than the first temperature difference, it indicates that the temperature difference between the indoor ambient temperature and the set temperature is less than the preset temperature difference range. In other words, the temperature difference between the indoor ambient temperature and the set temperature is small or has reached the set temperature. Since the cooling operation duration after the air conditioner is started is the first duration, it indicates that the cooling set temperature is high and the probability of condensation is low. At this time, the PTC heating device is controlled to be in the off state, and the air conditioner can operate normally in cooling mode, thereby reducing power consumption and saving energy.

[0082] The control device provided by the present invention is described below. The control device described below and the air conditioning anti-condensation control method described above can be referenced to each other.

[0091] On the other hand, the present invention further provides an air conditioner, comprising an air conditioner body, a PTC heating device and the electronic device provided by the above embodiment.

[0092] Among them, Figures 2 to 6 As shown, the PTC heating device includes a first conductive member 1, at least two second conductive members 2, and at least two PTC heating layers 3. The first conductive member 1 is disposed between the at least two second conductive members 2. Each PTC heating layer 3 is disposed between the first conductive member 1 and one of the second conductive members 2, and both sides of the PTC heating layer 3 are in conductive contact with the first conductive member 1 and the second conductive member 2, respectively. The PTC heating layer 3 includes a first PTC heating layer and a second PTC heating layer. The first PTC heating layer has a first operating temperature, the second PTC heating layer has a second operating temperature, and the first operating temperature is greater than the second operating temperature. The PTC heating device also includes a heat sink 4 and an insulating layer 5. The heat sink 4 includes a housing 41 having an installation cavity formed therein. The first conductive member 1, the second conductive member 2, and the PTC heating layer 3 are all inserted into the installation cavity. The connection end of the first conductive member 1 and the connection ends of the at least two second conductive members 2 extend out of the same end of the housing 41 and are staggered in the longitudinal direction of the housing 41. The insulating layer 5 covers the outside of the first conductive member 1, the second conductive member 2, and the PTC heating layer 3 and is disposed in the installation cavity.

[0093] In this embodiment, at least two PTC heating layers 3, the first conductive member 1, and the at least two second conductive members 2 form at least two heating elements, and the at least two heating elements together constitute a multi-layer heating element. The insulating layer 5 is wrapped around the outside of the arranged multi-layer heating element, and then the multi-layer heating element is inserted as a whole into the installation cavity of the shell 41. The installation cavity forms a heating space for the multi-layer heating element, and the insulating layer 5 is used for insulation between the multi-layer heating element and the inner wall of the shell 41. The connecting end of the first conductive member 1 and the connecting end of the at least two second conductive members 2 both extend out of the same end of the shell 41, and are staggered in the length direction of the shell 41, and are used to connect to the wiring terminals of the external power supply circuit respectively, thereby transmitting current to the PCT heating layer 3. The heat generated by the PCT heating layer 3 when it is energized is transferred to the heat sink 4 through heat conduction. The heat sink 4 is used to dissipate heat outward, thereby realizing the heating function.

[0094] When any one of the second conductive elements 2 and the first conductive element 1 is electrically connected, the PTC heating layer 3 located between the second conductive element 2 and the first conductive element 1 is energized and generates heat, that is, one heating body generates heat; when any two or more parts of the second conductive elements 2 and the first conductive element 1 are electrically connected, multiple PTC heating layers 3 located between the parts of the second conductive element 2 and the first conductive element 1 are electrically connected and generate heat, that is, multiple heating bodies generate heat; when all the second conductive elements 2 and the first conductive element 1 are electrically connected, all the PTC heating layers 3 are energized and generate heat, that is, the multi-layer heating body generates heat as a whole, thereby realizing multi-stage heating control.

[0095] The air conditioner of this embodiment is provided with multiple PTC heating layers 3 and multiple second conductive elements 2 through the PTC heating device to form multiple heating bodies. The multiple PTC heating layers 3 can be controlled to be energized and heated separately or simultaneously as needed to realize multi-stage heating control. It can be used in different cold and hot scenes to meet multi-mode application requirements. Moreover, the multiple PTC heating layers 3 form a multi-layer heating body with a stacked structure with the first conductive element 1 and the multiple second conductive elements 2. The structure is compact, which saves space while increasing power density, improving usage effect, and greatly improving user comfort. At the same time, by arranging the connection end of the first conductive element 1 and the connection end of the multiple second conductive elements 2 in a staggered arrangement, the circuit connection structures of the first conductive element 1 and the second conductive element 2 are staggered with each other, which is convenient for installation, helps to reduce space occupation, and is beneficial to insulation, avoiding breakdown, leakage short circuit, etc. caused by the circuit connection structures being too close. The insulation performance is good while occupying a small space.

[0096] Specifically, if Figure 3 、 Figure 4 and Figure 5As shown, the heat sink 4 further includes a plurality of heat sinks 42, which are connected to the outer side of the housing 41 and are spaced apart along the length of the housing 41. The provision of multiple heat sinks 42 effectively increases the heat dissipation area of the heat sink 4, improves the heat dissipation efficiency, and thereby improves the heating efficiency of the PCT heating device and enhances its performance.

[0097] Specifically, a plurality of heat sinks 42 are provided on two opposite outer side surfaces of the housing 41 , which further increase the heat dissipation area of the heat sink 4 and improve the heating efficiency.

[0098] Furthermore, a plurality of heat sinks 42 are provided on four outer side surfaces of the housing 41 .

[0099] In one embodiment, Figure 2 、 Figure 3 and 5 As shown, the PTC heating device further includes a mounting member 6, to which the heat sink 4, the connection end of the first conductive member 1, and the connection ends of the plurality of second conductive members 2 are fixedly connected, and the mounting member 6 insulates and isolates the connection end of the first conductive member 1 from the connection ends of the plurality of second conductive members 2. By providing the mounting member 6, the first conductive member 1, the second conductive member 2, and the heat sink 4 are mounted and fixed more firmly and stably. The heat sink 4 and the multi-layer heating element do not need to be directly fixedly connected, which is conducive to ensuring the insulation effect between the multi-layer heating element and the heat sink 4. Moreover, the mounting member 6 insulates and isolates the connection end of the first conductive member 1 from the connection ends of the plurality of second conductive members 2, thereby avoiding breakdown, leakage short circuit, and the like between the connection ends, and thus improving the insulation performance.

[0100] Specifically, the mounting member 6 is made of insulating material, such as ceramic, plastic, rubber, etc.

[0101] Specifically, if Figure 3 and Figure 5 As shown, a first socket 61 and multiple second sockets 62 are provided in the mounting member 6, and a first connecting groove 63 and multiple second connecting grooves 64 are also provided on the side of the mounting member 6. The first socket 61 is connected to the first connecting groove 63, and the multiple second sockets 62 are connected to the multiple second connecting grooves 64 in a one-to-one correspondence, and the first connecting groove 63 is located on the side of the second connecting groove 64 away from the second socket 62; the connecting end of the first conductive member 1 is plugged and fixed in the first socket 61, and the end of the first conductive member 1 extends into the first connecting groove 63; the connecting end of the second conductive member 2 is plugged and fixed in the second socket 62, and the end of the second conductive member 2 extends into the second connecting groove 64.

[0102] In this embodiment, by providing a first plug-in hole 61 and a fixed connection with the first conductive member 1, and a second plug-in hole 62 and a fixed connection with the second conductive member 2, the structure is simple and the connection is firm and stable; the end of the first conductive member 1 extends into the first connecting groove 63, so that the connection end of the first conductive member 1 is exposed from the first connecting groove 63, and the first conductive member 1 is connected to the external power supply line at the position of the first connecting groove 63; the end of the second conductive member 2 extends into the second connecting groove 64, so that the connection end of the second conductive member 2 is exposed from the second connecting groove 64, and the second conductive member 2 is connected to the external power supply line at the position of the second connecting groove 64; and the first connecting groove 63 is located on the side of the second connecting groove 64 away from the second plug-in hole 62, that is, the first connecting groove 63 and the second connecting groove 64 are located at different positions on the side of the mounting member 6, so that the circuit connection positions of the first conductive member 1 and the second conductive member 2 are respectively located at different positions on the side of the mounting member 6, effectively ensuring the insulation isolation effect of the connection end of the first conductive member 1 and the connection ends of the plurality of second conductive members 2, and convenient installation, improving the use effect.

[0103] Specifically, the second connection grooves 64 are respectively provided on different sides of the mounting member 6, which is conducive to ensuring that the circuit connection structures of the plurality of second conductive members 2 are staggered with each other, thereby ensuring the insulation effect.

[0104] In an embodiment not shown, the first jack 61 may also pass through the end face of the mounting member 6, and the mounting member 6 does not need to be provided with the first connecting groove 63. The end of the first conductive member 1 extends out of the end face of the mounting member 6, that is, the first conductive member 1 is connected to the external power supply circuit at the end face position of the mounting member 6; at the same time, the second conductive member 2 is connected to the external power supply circuit at the side position of the mounting member 6, so that the circuit connection positions of the first conductive member 1 and the second conductive member 2 are respectively located on different sides of the mounting member 6, which has a better insulation isolation effect on the connection end of the first conductive member 1 and the connection ends of the multiple second conductive members 2.

[0105] Specifically, the extension directions of the first insertion hole 61 and the plurality of second insertion holes 62 are parallel to each other, and the first insertion hole 61 and the plurality of second insertion holes 62 are spaced apart from each other in a direction perpendicular to the extension direction. Thus, the length directions of the first conductive member 1 and the plurality of second conductive members 2 are parallel to each other, and spaced apart from each other in a direction perpendicular to their lengths.

[0106] In one embodiment, Figure 2 and Figure 3 As shown, the PTC heating device further includes a fixing member 7, and the ends of the heat sink 4, the first conductive member 1, and the plurality of second conductive members 2 away from the mounting member 6 are all fixedly connected to the fixing member 7. The ends of the heat sink 4, the first conductive member 1, and the plurality of second conductive members 2 are respectively fixed by the mounting member 6 and the fixing member 7, making the structure more stable and reliable.

[0107] Specifically, the first conductive member 1 and the second conductive member 2 may be conductive plates or conductive strips, which are parallel to each other and spaced apart, and the PTC heating layer 3 is clamped and fixed between the first conductive member 1 and the second conductive member 2. The ends of the conductive plates or conductive strips are fixed by mounting members 6 and fixing members 7 to ensure that the PTC heating layer 3 is firmly and stably clamped, preventing the first conductive member 1 and the second conductive member 2 from piercing the insulating layer 5 and causing leakage short circuit, thereby ensuring insulation from the housing 41.

[0108] Specifically, the insulating layer 5 includes at least two layers of insulating film. By providing two or more layers of insulating film, the strength of the insulating layer 5 is improved, and the insulating layer 5 wraps and fixes the multi-layer heating element structure more firmly, stably and reliably. This effectively prevents the shell 41 of the heat sink 4 from piercing the insulating layer 5, or the first conductive element 1, the second conductive element 2, and the PTC heating layer 3, when the multi-layer heating element is installed in the shell 41, causing leakage short circuit, thereby ensuring the insulation effect between the multi-layer heating element and the shell 41.

[0109] In a specific embodiment, the insulating film is a polyesterimide film.

[0110] Specifically, if Figure 4 As shown, the PTC heating layer 3 includes a plurality of PTC heating sheets 31 arranged along the length direction. The plurality of PTC heating sheets 31 are connected in sequence to form the PTC heating layer 3, which is conducive to achieving a higher heating power density, improving the use effect, and at the same time helping to reduce costs and having strong practicality.

[0111] Specifically, the lengths of the first conductive member 1 and the second conductive member 2 are both greater than the length of the PTC heating layer 3, and the widths of the first conductive member 1 and the second conductive member 2 are greater than or equal to the width of the PTC heating sheet 31, so that the first conductive member 1 and the second conductive member 2 can effectively clamp and fix multiple PTC heating sheets 31 and arrange them to form the PTC heating layer 3, and it is also beneficial to prevent the PTC heating sheet 31 from puncturing the insulating film and causing short circuit leakage, which is stable, reliable and practical.

[0112] In one embodiment, the multiple PTC heating layers 3 each include a different type of PTC heating sheet 31. By using different types of PTC heating sheets 31, different PTC heating layers 3 have different heating power densities and heating characteristics, such as different Curie temperatures. By selecting different PTC heating layers 3 for power supply and heating as needed, the requirements of more specific application scenarios can be met, the use effect can be improved, and the scope of application is wider.

[0113] Of course, in other embodiments, the PTC heating sheets 31 of all PTC heating layers 3 may be of the same type, and the heating power may be selected by selecting and combining different numbers of PTC heating layers 3. Alternatively, the PTC heating sheets 31 of a portion of the PTC heating layers 3 may be of the same type, while the PTC heating sheets 31 of another portion of the PTC heating layers 3 may be of different types, thereby providing a wider range of choices, making use more convenient and flexible, improving the use effect, and being able to meet the use requirements of more application scenarios.

[0114] In one embodiment, Figure 3 and Figure 4 As shown, there are two second conductive members 2 , which are symmetrically stacked on opposite sides of the first conductive member 1 , and two PTC heating layers 3 are respectively connected between the two second conductive members 2 and the first conductive member 1 .

[0115] In this embodiment, two second conductive members 2 and a first conductive member 1 are arranged in a stacked arrangement, and two PTC heating layers 3 are clamped between the three conductive members to form a double-stacked PTC heating element structure. The structure is simple and compact, and the two PTC heating layers 3 are controlled to be energized and heated separately as needed to achieve multi-stage control, which can meet multi-mode application requirements.

[0116] When the PTC heating device of this embodiment is in use, the first conductive member 1 and the two second conductive members 2 are energized in the order of live wire / neutral wire / neutral wire, or neutral wire / live wire / live wire.

[0117] In another embodiment, Figure 6 As shown, the number of second conductive members 2 is greater than two, and a plurality of second conductive members 2 greater than two are arranged at intervals around the periphery of the first conductive member 1, and a PTC heating layer 3 is connected between each second conductive member 2 and the first conductive member 1. By arranging a plurality of second conductive members 2 at intervals around the periphery of the first conductive member 1, a plurality of PTC heating layers 3 are arranged in a one-to-one correspondence with the plurality of second conductive members 2, thereby forming a plurality of heating elements arranged around the periphery of the first conductive member 1, forming a multi-layer heating element structure stacked in an annular manner, realizing more than two heating elements, a compact structure, reducing occupied space, and increasing air filter density. The plurality of PTC heating layers 3 are controlled to be energized and heated separately as needed, realizing multi-stage control, and being able to meet the needs of more mode applications.

[0118] Specifically, the first conductive member is a hollow shaft, and the plurality of PTC heating sheet layers are located between the second electrode plate and the first electrode plate.

[0119] In a specific embodiment, Figure 6As shown, the first conductive part 1 is a conductive shaft, such as a hollow shaft, a cylindrical shaft, etc.; the second conductive part 2 is an arc-shaped conductive plate, and three arc-shaped conductive plates are arranged at intervals around the outer periphery of the conductive shaft; the cross-section of the PTC heating layer 3 is fan-shaped, and the three PTC heating layers 3 are also arranged at intervals around the outer periphery of the conductive shaft, and are conductively fixedly connected to the conductive shaft, and the outer side of the PTC heating layer 3 is conductively fixedly connected to the arc-shaped conductive plate, thereby forming a fan-shaped heating body; the three fan-shaped heating bodies are combined to form a cylindrical heating body.

[0120] Of course, the first conductive element 1 can also be a prism axis, such as a triangular prism, a quadrangular prism, a hexagonal prism, etc., which can form a heating element in the shape of a triangular prism, a quadrangular prism, or a hexagonal prism.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
