DETAILED DESCRIPTION

[0076] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0077] In the embodiment of the present application, an air conditioner 10 is provided, which is configured to be installed in a designated area and provide air conditioning to the designated area, thereby improving the air quality in the designated area and improving the comfort of the user. The air conditioning function may include temperature regulation, humidity regulation, fresh air exchange, and wind speed regulation. In the embodiment of the present application, the fresh air exchange function of the air conditioner 10 is taken as an example for description.

[0078] In the prior art, when the designated area is subjected to fresh air exchange, the fresh air introduces the air of the external environment into the designated area, and the air in the designated area is led out to the external environment; therefore, due to the difference in temperature and humidity of the external environment, the fresh air may affect the air conditioning function of the designated area. In order to ensure the air conditioning function of the designated area, the air conditioner 10 increases the operating power, which causes the fresh air to increase the energy consumption of the air conditioner 10. In addition, since the addition of the fresh air exchange function requires the opening of an additional air inlet and air outlet for fresh air exchange on the wall of the designated area, this not only increases the cost but also has a significant impact on the appearance.

[0079] To improve the above technical issues, please refer to Figure 1 and Figure 2 , an air conditioner 10 of the present application is provided.

[0080] The air conditioner 10 includes an air conditioner main body 100, a fresh air component 200 and a controller 300. The air conditioner main body 100 can be configured to provide a temperature regulation function to a designated area. In other words, the air conditioner main body 100 can have an air guide (not shown in the figure), which can guide the airflow passing through the evaporator to the designated area, thereby providing a temperature regulation function to the designated area. In addition, the air conditioner main body 100 also has an air inlet 110, which is configured to lead the air in the designated area to the inside of the air conditioner main body 100 and guide the airflow to the evaporator. It should be noted that in order to facilitate the circulation of the refrigerant between the outdoor unit and the indoor unit of the air conditioner 10, and in order for the indoor unit to export condensed water to the outside, a perforation is opened on the wall of the designated area, and the refrigerant pipe between the indoor unit and the outdoor unit and the drainage pipe of the indoor unit all pass through the perforation and extend to the outside of the designated area.

[0081] The fresh air exchange component 200 includes a channel tube 210 , a total heat exchanger 220 and an air guide component 230 .

[0082] Among them, the full heat heat exchanger 220 is installed on the air conditioner body 100, and a ventilation channel (not marked in the figure) is formed on the full heat heat exchanger 220. When the air flow passes through the core of the full heat heat exchanger 220, full heat exchange can be performed with the air flow through the core. When the air conditioner 10 is heating, the heat can be absorbed by the core to heat the fresh air intake, and when the air conditioner 10 is cooling, the cold can be absorbed by the core to cool the fresh air intake, thereby preventing the fresh air from affecting the air conditioning of the designated area.

[0083] The channel tube 210 is connected to the total heat exchanger 220, and the internal channel of the channel tube 210 is connected to the ventilation channel. The channel tube 210 can be configured to supply air to the total heat exchanger 220, and the channel tube 210 is also configured to export the airflow exported by the total heat exchanger 220. It should be noted that one end of the channel tube 210 is connected to the total heat exchanger 220, and the other end of the channel tube 210 can extend to the outside of the designated area through the above-mentioned perforation, so as to facilitate the channel tube 210 to inhale the airflow from the outside to achieve fresh air. It should be noted that it is precisely because the air intake and air outlet of the fresh air exchange component 200 are achieved through the channel tube 210, so that the fresh air exchange function can be achieved by adding a pipeline, so that the added pipeline can be extended from the perforation, which can solve the problem of increased cost and appearance caused by the need to open additional installation holes on the wall of the designated area in the prior art.

[0084] The air guide assembly 230 is connected to the total heat exchanger 220, and the air guide assembly 230 is configured to guide the airflow to flow through the ventilation channel and the channel tube 210 in sequence to exhaust air in the first operating state. In other words, when the air guide assembly 230 is in the first operating state, the air guide assembly 230 can absorb air from the designated area and guide the airflow to be discharged from the ventilation channel and the channel tube 210, thereby achieving the purpose of exhausting fresh air; in addition, the air guide assembly 230 is also configured to guide the airflow to flow through the channel tube 210 and the ventilation channel in sequence to intake air in the second operating state. In other words, when the air guide assembly 230 is in the second operating state, the air guide assembly 230 can absorb air from the external environment through the channel tube 210, and guide the inhaled airflow to the designated area in sequence along the channel tube 210, the ventilation channel and the air guide assembly 230. Among them, by switching the air guide assembly 230 between the first operating state and the second operating state, intermittent air intake and air discharge of the designated area can be achieved, so as to achieve the purpose of providing a fresh air exchange function for the designated area.

[0085] It should be noted that in the embodiment of the present application, when the air guide component 230 is taking in air, the air guide component 230 guides the airflow to the air inlet 110 of the air-conditioning body 100, so that the airflow introduced into the designated area can flow through the evaporator in the air-conditioning body 100, and can supplement the coldness in the introduced airflow in the case of cooling, and can supplement the heat of the introduced airflow in the case of heating, thereby ensuring the air conditioning effect on the designated area.

[0086] In addition, the controller 300 is electrically connected to the air guide assembly 230, and the controller 300 is configured to control the air guide assembly 230 to switch between the first operating state and the second operating state, so as to achieve the purpose of providing fresh air to the designated area.

[0087] The controller 300 may be an integrated circuit chip with signal processing capability. The controller 300 may be a general-purpose processor, including a central processing unit (CPU), a single-chip microcomputer, a microcontroller unit (MCU), a complex programmable logic device (CPLD), a field programmable gate array (FPGA), an application-specific integrated circuit (ASIC), an embedded ARM, and the like. The controller 300 may implement or execute the disclosed methods, steps, and logic diagrams in the embodiments of the present invention.

[0088] In a feasible implementation, the air conditioner 10 may further include a memory for storing program instructions executable by the controller 300. The memory may be an independent external memory, including but not limited to a random access memory (RAM), a read only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), and an electrically erasable read-only memory (EEPROM). The memory may also be integrated with the controller 300, for example, the memory may be integrated with the controller 300 in the same chip.

[0089] As described above, the fresh air exchange component 200 in the air conditioner 10 can be provided with only one channel tube 210 to realize the fresh air intake and exhaust, which can not only realize the purpose of fresh air exchange for the designated area, but also can be provided with the channel tube 210 in the wall hole provided when the air conditioner 10 is installed, thereby solving the technical problem of increasing the cost and affecting the appearance by providing additional air inlets and air outlets. In addition, the fresh air exchange component 200 adopts a full heat heat exchanger 220 for air intake and air exhaust, and the air conditioner 10 can control the air guide component 230 to switch between the first operating state and the second operating state through the controller 300, so that the air intake airflow and the air exhaust airflow in the fresh air exchange function can be fully heat exchanged, thereby preventing the fresh air from affecting the air conditioning of the designated area, thereby reducing the energy consumption of the air conditioner 10.

[0090] Optionally, in some embodiments of the present application, in order to facilitate intermittent air intake and outlet of a channel tube 210 to achieve a fresh air function, and at the same time to achieve effective full heat exchange in the ventilation channel, the full heat heat exchanger 220 can adopt a rotary full heat heat exchanger 220.

[0091] Wherein, in the case where the total heat exchanger 220 adopts a rotary total heat exchanger 220, the ventilation channel includes an air inlet channel and an air outlet channel; the air inlet channel and the air outlet channel are both connected to the interior of the channel tube 210, and the air inlet channel is configured to guide the airflow introduced by the channel tube 210 to enter the air, and the air outlet channel is configured to guide the airflow into the channel tube 210 to exhaust the air. It should be noted that in the rotary total heat exchanger 220, a rotatable core is provided inside, and the core is partially located in the air inlet channel and partially located in the air outlet channel; at the same time, when the core rotates, part of the core located in the air inlet channel will also rotate into the air outlet channel, so that after the airflow in the air outlet channel exchanges heat with the core, the core is transferred into the air inlet channel to transfer heat or cold to the airflow in the air inlet channel, so as to preheat or precool the airflow in the air inlet channel, thereby preventing the airflow introduced into the designated area by the fresh air function from affecting the air conditioning function of the designated area and causing energy consumption to increase, thereby achieving the purpose of reducing energy consumption.

[0092] Optionally, in order to facilitate the air intake and air discharge of the channel tube 210, in an embodiment of the present application, the channel tube 210 may include a duct portion 211 and an air guide cavity 212, wherein the air guide cavity 212 is connected to the shell of the total heat exchanger 220, and the air guide cavity 212 is arranged outside the total heat exchanger 220 to prevent the air guide cavity 212 and the air guide assembly 230 from interfering with each other. The air guide cavity 212 has a cavity inside, and the cavity is connected to the ventilation channel, and the ventilation area of ​​the cavity is larger than the ventilation area of ​​the internal channel of the duct portion, and the cavity is configured to increase the communication area between the channel tube 210 and the ventilation channel, thereby facilitating the air intake and air discharge of the channel tube 210. One end of the duct portion 211 is connected to the air guide cavity 212, and the other end is configured to extend into the external environment, so that the airflow is guided to the external environment through the duct portion 211, or the air is sucked from the external environment through the duct portion 211.

[0093] In one embodiment of the present application, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5The air guide assembly 230 may include a first fan 231 and a second fan 232, both of which are connected to the total heat exchanger 220, and the first fan 231 is connected to the exhaust passage, and the second fan 232 is connected to the air inlet passage. When the air guide assembly 230 is operated in the first operating state, the first fan 231 is operated, and the first fan 231 guides the airflow to flow through the exhaust passage and the channel pipe 210 in sequence to exhaust air; in other words, when the first fan 231 is operated, the first fan 231 can absorb air from the designated area, and guide the airflow from the exhaust passage and the channel pipe 210 to the external environment of the designated area. In addition, when the air guide component 230 is operating in the second operating state, the second fan 232 is operating, and the second fan 232 guides the airflow to flow through the channel tube 210 and the air inlet channel in sequence to intake air; in other words, when the second fan 232 is operating, the second fan 232 can draw air from the external environment through the channel tube 210, and guide the airflow to flow through the channel tube 210, the air inlet channel and the second fan 232 in sequence and introduce it into the designated area.

[0094] Optionally, the air guide assembly 230 may further include a shell 201, which is connected to the shell of the total heat exchanger 220, and a first cavity 202 and a second cavity 203 are formed inside the shell 201, and the first cavity 202 and the second cavity 203 are connected to each other. A through hole 221 is also provided at the connection between the shell 201 and the total heat exchanger 220, and the through hole 221 is connected to both the first cavity 202 and the second cavity 203. At the same time, the through hole 221 is also connected to the internal space of the total heat exchanger 220, so that the first fan 231 in the first cavity 202 can suck air from the designated area when in operation, and the through hole 221 can guide the airflow into the interior of the total heat exchanger 220, so as to guide the airflow from the exhaust channel and the channel pipe 210; and the second fan 232 in the second cavity 203 can guide the airflow guided by the total heat exchanger 220 to the interior of the designated area from the through hole 221 when in operation.

[0095] In addition, in order to facilitate the first fan 231 to suck air from the designated area, an air suction port 2311 is opened on the shell 201. The air suction port 2311 is connected to the first cavity 202 and is configured to be set close to the air inlet 110 of the air conditioner body 100.

[0096] Of course, see Figure 6In another embodiment of the present application, the air guide component 230 may include a two-way fan 233, which can rotate forward and reverse, and the air outlet direction of the two-way fan 233 in the forward rotation state is opposite to the air outlet direction of the two-way fan 233 in the reverse rotation state. Among them, when the air guide component 230 is operated in the first operating state, the two-way fan 233 rotates forward and guides the airflow to flow through the exhaust channel and the channel pipe 210 in sequence to exhaust air; in addition, when the air guide component 230 is operated in the second operating state, the two-way fan 233 reverses and guides the airflow to flow through the channel pipe 210 and the air inlet channel in sequence to intake air. Therefore, the intermittent forward and reverse rotation of the two-way fan can achieve fresh air in the designated area.

[0097] Also, see Figure 7 In another embodiment of the present application, the air guide assembly 230 includes a third fan 234, a first channel 235, and a second channel 236. The first fan 231 is connected to the total heat exchanger 220 and communicates with the ventilation channel, so that the first fan 231 can guide the airflow into the ventilation channel or suck air from the ventilation channel. The two ends of the first channel 235 are respectively connected to the channel tube 210 and the total heat exchanger 220, so that the first channel 235 can guide the airflow from the ventilation channel to the channel tube 210. The two ends of the second channel 236 are respectively connected to the channel tube 210 and the air inlet end of the third fan 234, so that the third fan 234 can suck air from the second channel 236. When the air guide assembly 230 is operated in the first operating state, the first channel 235 is turned on and guides the airflow to flow through the ventilation channel, the first channel 235, and the channel tube 210 in sequence to exhaust air. When the air guide assembly 230 operates in the second operating state, the second channel 236 is turned on and guides the airflow to flow through the channel tube 210, the second channel 236 and the ventilation channel in sequence. It should be noted that when the first channel 235 is turned on, the second channel 236 is turned off; similarly, when the second channel 236 is turned on, the first channel 235 is turned off. Thus, the opening and closing of the first channel 235 and the second channel 236 realize the fresh air in the designated area.

[0098] Of course, please refer to Figure 2-Figure 7In the embodiment of the present application, in order to reduce the cleaning frequency of the air guide assembly 230, the fresh air replacement assembly 200 may optionally further include a first filter 241, which is disposed inside the channel tube 210, so that foreign matter such as dust in the airflow can be filtered when air is sucked from the channel tube 210, thereby reducing foreign matter such as dust in the airflow, thereby improving the quality of fresh air. In addition, dust accumulation on the air guide assembly 230 can be prevented, thereby achieving the purpose of reducing the cleaning frequency of the air guide assembly 230. Similarly, in order to improve the quality of fresh air, the fresh air exchange component 200 may also include a second filter 242, which is disposed at the air inlet of the air guide component 230, and the second filter 242 is configured to filter the airflow introduced into the air guide component 230; in other words, dust and other foreign matter entering the air guide component 230 may be filtered by the second filter 242, thereby allowing the dust in the designated area to be filtered by the second filter 242, which may reduce the dust and other foreign matter entering the air guide component 230, thereby reducing the cleaning frequency of the air guide component 230.

[0099] It should be understood that in other embodiments of the present application, the first filter 241 and the second filter 242 may be omitted. For example, the first filter 241 may be omitted. In this case, the dust entering from the air inlet of the air guide assembly 230 may be filtered by the second filter 242, thereby reducing the dust in the air guide assembly 230 to achieve the purpose of reducing the cleaning frequency of the air guide assembly 230. For another example, the second filter 242 may be omitted, and the dust in the airflow introduced from the external environment may be filtered by the first filter 241, thereby reducing the cleaning frequency of the air guide assembly 230.

[0100] Optionally, see Figure 1 and Figure 2 In the embodiment of the present application, in order to facilitate the control of the air guide component 230, so as to achieve effective fresh air exchange for the designated area and solve the technical problem of increased energy consumption. The air conditioner 10 may also include at least one of a first temperature detection device 310, a second temperature detection device 320 and a third temperature detection device 330. Among them, the first temperature detection device 310 is installed in the channel tube 210, and the first temperature detection device 310 is configured to detect the outer ring temperature value, and the outer ring temperature value represents the temperature of the external environment. The second temperature detection device 320 is installed in the total heat exchanger 220, and the second temperature detection device 320 is configured to detect the total heat exchange temperature value, and the total heat exchange temperature value represents the temperature inside the total heat exchanger 220. The third temperature detection device 330 is installed at the air inlet of the air guide component 230, and the third temperature sensor is configured to detect the exhaust temperature value, and the exhaust temperature value represents the temperature at the air inlet when the air guide component 230 derives the airflow.

[0101] It should be noted that the air conditioner 10 includes a first temperature detection device 310, a second temperature detection device 320 and a third temperature detection device 330. The first temperature detection device 310, the second temperature detection device 320 and the third temperature detection device 330 are all electrically connected to the controller 300, and the first temperature detection device 310, the second temperature detection device 320 and the third temperature detection device 330 can send the detected outer ring temperature value, the total heat exchange temperature value and the exhaust temperature value to the controller 300, and the controller 300 controls the air guide component 230 to switch between the first operating state and the second operating state according to the outer ring temperature value, the total heat exchange temperature value and the exhaust temperature value.

[0102] Based on the air conditioner 10 provided above, please refer to Figure 8 In some embodiments of the present application, a fresh air control method is also provided, which is used to solve the problem that fresh air increases the energy consumption of the air conditioner 10. The fresh air control method may include:

[0103] Step S10: receiving an intake air temperature value.

[0104] The intake air temperature value indicates the temperature of the air inlet 110 of the air conditioner body 100. Of course, in the embodiment of the present application, a temperature detection device may be provided at the air inlet 110 to detect the intake air temperature value at the air inlet 110. Of course, the temperature detection device may be electrically connected to the controller 300 to send the intake air temperature value to the controller 300.

[0105] Step S20: issuing a fresh air exchange signal according to the intake air temperature value and the first preset temperature value.

[0106] The fresh air signal is configured to control the air guide assembly 230 to operate in the first operating state. In other words, when the intake air temperature value and the first preset temperature value meet the preset conditions, the fresh air assembly 200 is controlled to start operating with exhaust air. At this time, the core of the total heat exchanger 220 can be preheated or precooled by the airflow inside the designated area, so that the total heat exchanger 220 can preheat or precool the intake airflow.

[0107] Optionally, see Fig. 9 , step S20 may include:

[0108] Step S21, calculating the difference between the intake air temperature value and the first preset temperature value to obtain the temperature difference value.

[0109] The temperature difference may represent the absolute value of the difference between the intake air temperature value and the first preset temperature value. In other words, the temperature difference may represent the degree of proximity between the intake air temperature value and the first preset temperature value.

[0110] Step S22: determine whether the temperature difference is greater than or equal to a fourth preset value.

[0111] Optionally, in some embodiments of the present application, the value range of the fourth preset value may be 2°C-5°C. In other words, the value of the fourth preset value may be 2°C, 3°C, 4°C or 5°C.

[0112] Step S23: If the temperature difference is less than a fourth preset value, a fresh air signal is issued.

[0113] Step S23 can also be regarded as the judgment result in step S22 being no. At this time, since the temperature difference is less than the fourth preset value, it indicates that the intake temperature is close to the first preset temperature. In this case, fresh air exchange can reduce the impact on the air conditioning effect in the designated area, thereby ensuring effective air conditioning inside the designated area to ensure the comfort of the user.

[0114] It should be noted that in other embodiments of the present application, other methods may be used to determine whether the air conditioner 10 performs fresh air exchange. For example, when the air conditioner 10 has been running for a preset time and has not yet performed fresh air exchange, in this case, the air guide assembly 230 may be controlled to start running in the first operating state. The preset time may range from 1h to 3h. In other words, the preset time may be 1h, 1.5h, 2h, 2.5h, or 3h.

[0115] Of course, in other embodiments of the present application, the issuance of the fresh air signal may also be based on other conditions. For example, the fresh air signal may be issued based on an instruction issued by the user end, wherein the user may issue an instruction through a remote control, an intelligent terminal, or a set gesture, so that the controller 300 may issue a fresh air signal based on the instruction. For another example, a dust sensor or a carbon dioxide sensor may be provided to issue an instruction when the dust content or carbon dioxide content in the specified area is detected to be greater than a set threshold, and the controller 300 issues a fresh air control signal based on the instruction.

[0116] Please continue reading Figure 8 After a fresh air exchange signal is issued in step S20, and the air guide assembly 230 is controlled to start operating in the first operating state according to the fresh air exchange signal, the fresh air control method further includes:

[0117] Step S30, receiving the total heat exchange temperature value, the exhaust temperature value and the outer ring temperature value.

[0118] The total heat exchange temperature value is obtained by detecting the temperature inside the total heat exchanger 220 by the second temperature detection device, and is sent to the controller 300 by the second temperature detection device 320. The exhaust temperature value is obtained by detecting the temperature at the air inlet when the air guide assembly 230 outputs the airflow by the third temperature detection device 330, and is sent to the controller 300 by the third temperature detection device 330. The outer ring temperature value is obtained by detecting the temperature of the channel pipe 210 by the first temperature detection device 310, and is sent to the controller 300 by the first temperature detection device 310.

[0119] Step S40: issuing a switching signal according to the total heat exchange temperature value, the exhaust temperature value and the outer ring temperature value.

[0120] The switching signal is configured to control the air guide assembly 230 to switch between the first operating state and the second operating state.

[0121] It should be noted that the temperature at the air inlet of the air guide component 230 can represent the ambient temperature inside the designated area. When the outer ring temperature value representing the external ambient temperature is significantly different from the exhaust temperature value representing the internal ambient temperature, directly introducing the air from the external environment into the designated area will affect the air conditioning of the designated area. Therefore, it is necessary to preheat or precool the airflow introduced from the external environment through the total heat exchanger 220 to prevent the intake of fresh air from affecting the air conditioning of the designated area. The operating state of the air guide component 230 can be switched according to the total heat exchange temperature value, the exhaust temperature value and the outer ring temperature value, so that the airflow can be effectively preheated or precooled through the total heat exchanger 220; and when the preheating or precooling effect of the total heat exchanger 220 is reduced, the operating state of the air guide component 230 can be switched to exhaust air to supplement the heat or cold of the core of the total heat exchanger 220, so as to ensure that the total heat exchanger 220 can effectively preheat or precool the intake of fresh air.

[0122] Optionally, the switching signal may include a first change signal and a second change signal, wherein the first change signal is configured to control the operation state of the air guide assembly 230 to switch from the first operation state to the second operation state, and the second change signal is configured to control the operation state of the air guide assembly 230 to switch from the second operation state to the first operation state; see Fig.10 In addition, step S40 may include:

[0123] Step S41: When the difference between the total heat exchange temperature value and the exhaust gas temperature value is less than or equal to a second preset value, a first change signal is issued.

[0124] When the difference between the exhaust temperature value and the total heat exchange temperature value is less than or equal to the second preset value, it means that the temperature difference between the core of the total heat exchanger 220 and the internal environment of the specified area is small, which means that the core of the total heat exchanger 220 has absorbed enough heat or cold, so that the total heat exchanger 220 can effectively preheat or pre-cool the fresh air intake. Therefore, in this case, the air guide assembly 230 can be switched to the air intake state.

[0125] Optionally, the value range of the second preset value may be 2°C-5°C. In other words, the value of the second preset value may be 2°C, 3°C, 4°C or 5°C.

[0126] Step S42: When the difference between the total heat exchange temperature value and the outer ring temperature value is less than or equal to the third preset value, a second change signal is issued.

[0127] When the difference between the outer ring temperature value and the total heat exchange temperature value is less than or equal to the third preset value, it means that the temperature difference between the core of the total heat exchanger 220 and the external environment is small. Therefore, it means that the core of the total heat exchanger 220 can no longer provide effective preheating or precooling. Therefore, it is necessary to switch the operating state of the air guide component 230 to the first operating state to heat or cool the core of the total heat exchanger 220 through airflow when exhaling fresh air.

[0128] Optionally, the value range of the third preset value may be 2°C-5°C. In other words, the value of the third preset value may be 2°C, 3°C, 4°C or 5°C.

[0129] As described above, the air conditioner 10 can be subjected to fresh air processing according to the air intake temperature value of the air conditioner 10, and the operating state of the air guide component 230 can be switched according to the total heat exchange temperature value, the exhaust temperature value and the outer ring temperature value, so as to realize intermittent air intake and outlet in the designated area through the channel pipe 210, prevent fresh air from affecting the air conditioning of the designated area, and reduce the energy consumption of the air conditioner 10.

[0130] Of course, see Fig.11 In some embodiments of the present application, the fresh air control method may further include:

[0131] Step S50, obtaining the running time value of the air guide assembly 230.

[0132] The running time value may start counting from when the air guide assembly 230 is started according to the fresh air signal.

[0133] Step S51: Determine whether the running time value is greater than or equal to a preset value.

[0134] The preset value may range from 0.5h to 2h. In other words, the preset value may range from 30min, 45min, 1h, 1.2h, 1.5h or 2 hours.

[0135] Step S52: If the running time value is greater than or equal to the preset value, the air guide assembly 230 is controlled to stop.

[0136] In other words, when the judgment result in step S51 is yes, it means that the fresh air exchange function has been running for a long enough time, so the operation of the fresh air exchange function can be suspended to save energy.

[0137] Of course, in other embodiments of the present application, the fresh air exchange action may also be stopped according to an instruction issued by the user. Alternatively, an instruction may be issued when the dust sensor or carbon dioxide sensor detects that the dust content or carbon dioxide content in the specified area is reduced to a set threshold, and the controller 300 stops the fresh air exchange action according to the instruction.

[0138] Based on the air conditioner 10 provided above, please refer to Fig.12 In some other embodiments of the present application, a fresh air control method is provided, which is used to solve the problem that fresh air increases the energy consumption of the air conditioner 10. The fresh air control method is the same as steps S10 to S20 of the fresh air control method provided above, and will not be repeated here. After step S20, the fresh air control method provided in this embodiment includes:

[0139] Step S300, receiving the fresh air operation time value.

[0140] The fresh air operation time value may represent the time when the air guide component 230 is started. In other words, the timing of the fresh air operation time value starts after the air guide component 230 is turned on according to the fresh air exchange signal.

[0141] Step S301: sending a switching signal according to the fresh air operation time value.

[0142] The switching signal is configured to control the operating state of the air guide assembly 230 to switch between a first operating state and a second operating state.

[0143] Among them, in step S301, the method that can be adopted can be as follows: when the fresh air operation time value reaches an integer multiple of the set value each time, a switching signal is issued in sequence. It should be noted that the switching signal in this method can control the air guide component 230 to switch to the second operating state when the air guide component 230 is in the first operating state, and the switching signal can also control the air guide component 230 to switch to the first operating state when the air guide component 230 is in the second operating state. It should be understood that in other methods, when the switching signal includes a first change signal and a second change signal, the first change signal can be issued when the fresh air operation time value reaches an even multiple of the set value each time, and the second change signal can be issued when the fresh air operation time value reaches an odd multiple of the set value each time.

[0144] Therefore, the air conditioner 10 can be processed with fresh air according to the suction temperature value of the air conditioner 10, and the operating state of the air guide component 230 can be switched according to the operating time of the air guide component 230, so as to realize intermittent air intake and outlet in the designated area through the channel pipe 210, prevent the fresh air from affecting the air conditioning of the designated area, and reduce the energy consumption of the air conditioner 10.

[0145] In summary, the air conditioner 10 and the fresh air control method provided in the embodiment of the present application can only set one channel tube 210 to realize the fresh air intake and outlet, which can not only realize the purpose of fresh air in the designated area, but also set the channel tube 210 in the wall hole set when the air conditioner 10 is installed, so as to solve the technical problem of increasing the cost and affecting the appearance by adding an additional air inlet and air outlet. In addition, the fresh air component 200 adopts a full heat heat exchanger 220 for air intake and air outlet, and the air conditioner 10 can control the air guide component 230 to switch between the first operating state and the second operating state through the controller 300, so that the air intake airflow and the air outlet airflow in the fresh air function are fully heat exchanged, thereby preventing the fresh air from affecting the air conditioning of the designated area, thereby reducing the energy consumption of the air conditioner 10.
