Figure 4 In the middle, the first cavity 15 is set as two. In order to better demonstrate the component structure of the air conditioner 100, Figure 5 China Figure 4 A partial cross-sectional view at position A in the middle.

[0147] In some embodiments, two fresh air modules are provided.

[0148] In some embodiments, two fresh air outlets 14 are provided. The two fresh air outlets are located on opposite sides of the indoor air outlet.

[0155] The technical solution in this application mainly targets concealed air conditioning products. To meet aesthetic requirements, the fresh air module must be completely hidden within the decorative panels on both sides. However, due to the need for filter replacement in the fresh air module, a location for filter replacement must be reserved. In this application, by creating a hole in the base plate 2, the cover 25 rotates open along one side after the switch on the cover 25 is turned on. Due to gravity, the cover 25 falls too quickly, which can lead to slow reaction time for disassembly personnel and a poor user experience.

[0156] In response to the problem that the cover plate 25 of the air conditioner 100 falls too fast in this application, this application adds a component at the pivot of the cover plate 25 to block the rotation of the cover plate 25, thereby reducing the rotation speed of the cover plate 25 and slowing down the falling speed, giving the user reaction time and improving the user experience.

[0157] Reference Figures 6-12 The air conditioner 100 includes a rotating shaft. The rotating shaft is mounted on the side of the base plate 2 near the top plate.

[0158] The air conditioner 100 includes a first mounting member 28. The first mounting member 28 is mounted on a cover plate 25. It is used for connection with a rotating shaft and can rotate along the rotating shaft.

[0159] The air conditioner 100 includes a first gear mounting member 29. The first gear mounting member 29 is mounted on a cover plate 25. It is used to connect to a rotating shaft and can rotate along the shaft. The first gear mounting member 29 and the first mounting member 28 operate synchronously.

[0160] The air conditioner 100 includes a damper assembly 30. The damper assembly 30 is mounted on one side of the rotating shaft. The damper assembly 30 is connected to a first gear mount 29 so that when the cover 25 rotates along the rotating shaft, the first gear mount 29 is subjected to resistance from the damper assembly 30 to slow down the rotational speed of the cover 25.

[0161] In some embodiments, the first gear mount 29 includes a first gear 253. The center of the first gear 253 is connected to a shaft and is rotatable along the shaft.

[0164] In some embodiments, the damper assembly 30 includes a second gear 302. The second gear 302 is connected to the damper 301 and meshes with a first gear 253. When the cover plate 25 rotates relative to the pivot, the first gear 253 receives a damping force from the damper 301 through the second gear 302.

[0165] In this application, for living room air conditioning scenarios or pre-installed ducted air conditioning scenarios, a cover plate 25 is provided directly below the corresponding fresh air module filter assembly. The cover plate 25 adopts a push-button touch switch (press-to-open). Figure 7 (Center arrow position) Open. By setting a damper assembly 30 on one side of the cover 25, and through the assembly method of gear and shaft connection, the resistance of the damper assembly 30 during rotation can effectively reduce the speed at which the cover 25 rotates and falls, giving the user reaction time, thereby avoiding the cover falling too quickly and giving the user a bad disassembly and assembly experience.

The second mounting portion 37 is disposed opposite to the first mounting portion 36, and a space for mounting the damper assembly 30 is formed between the first mounting portion 36 and the second mounting portion 37.

[0176] Reference Figures 11-12 The first mounting portion 36 and the second mounting portion 37 are symmetrically arranged. Taking one of them as an example, the first mounting portion 36 includes a main structure 352, on which an auxiliary mounting structure 351 is provided. A mounting space is formed between one side of the main structure 352 and the auxiliary mounting structure 351, which is used to accommodate one side of the damper assembly 30, so that the damper assembly 30 can be mounted between the first mounting portion 36 and the second mounting portion 37.

[0177] In some embodiments, the auxiliary mounting structure 351 extends from one side of the main structure 352. A protruding structure is provided at the end of the auxiliary mounting structure 351 away from the main structure 352. This protruding structure is located on the side away from the mounting space.

[0178] In some embodiments, the first mounting portion 36 and the second mounting portion 37 are provided with a circular opening on the side near the first gear 253 to accommodate the shape of the second gear 302.

[0180] In some embodiments, refer to Figure 10 The first mounting member 28 includes a first mounting component 254. The center of the first mounting component 254 is connected to the first rotating shaft 26 and is rotatable along the first rotating shaft 26.

[0181] In some embodiments, refer to Figure 10 The first mounting component 28 includes a first connector 251. One end of the first connector 251 is connected to the first mounting member 254, and the other end of the first connector 251 is connected to the cover plate body.

When the cover plate 25 rotates along the rotating shaft, the first gear mounting member 29 receives resistance from the damper assembly 30 to slow down the rotation speed of the cover plate 25. This allows the filter assembly 51 to fall off due to insufficient reaction time when the user opens the cover plate 25, based on the user's reaction time.

[0186] In some embodiments, refer to Figure 13 A switch assembly 4 is provided on the opposite side of the mounting port 24, and the switch assembly 4 is used to fix the cover plate 25 when the mounting port 24 is closed.

[0187] The cover 25 is opened by a push-button tactile switch using the switch assembly 4. After opening the cover 25, the filter assembly can be pulled out and replaced.

[0188] In some embodiments, the switch assembly 4 is used to fix the cover plate 25 when the cover plate 25 closes the assembly port 24 or to eject the cover plate 25 from the assembly port 24.

[0189] In some embodiments, the switch assembly 4 includes a spring-loaded latch 42. The spring-loaded latch 42 is mounted on the base plate 2 and is fixedly connected to the base plate 2.

[0190] The switch assembly 4 includes a spring-loaded body 41. The spring-loaded body 41 is mounted on the side of the cover plate 25 facing the interior of the inner housing and is fixedly connected to the cover plate 25.

[0191] The spring-loaded body 41 can be inserted into the spring-loaded buckle 42 and fixedly connected to the spring-loaded buckle 42 as the cover plate 25 moves, or the spring-loaded body 41 can be ejected from the spring-loaded buckle 42 and moved away from the spring-loaded buckle 42 by pressing the side of the spring-loaded body 41 away from the spring-loaded buckle 42, so as to drive one side of the cover plate 25 away from the assembly port 24, so as to take out the filter assembly through the assembly port 24.

[0192] When using the filter, the user can press the spring-loaded buckle 42, which will pop out of the spring-loaded body 41 and the cover 25 will fall down, thus opening the cover 25 to replace the filter.

[0193] In some embodiments, the switch assembly 4 includes a spring-loaded latch 42. The spring-loaded latch 42 is mounted on the side of the cover plate 25 facing the interior of the inner housing and is fixedly connected to the cover plate 25.

Alternatively, by pressing the side of the spring-loaded buckle 42 away from the spring-loaded body 41, the spring-loaded buckle 42 can be ejected from the spring-loaded body 41 and moved away from the spring-loaded body 41, thereby moving one side of the cover plate 25 away from the assembly port 24, so that the filter assembly can be removed through the assembly port 24.

[0196] In this application, the example shown is that the spring-loaded buckle 42 is installed on the base plate 2, and the spring-loaded body 41 is installed on the cover plate 25. (Refer to...) Figures 14-17 .

[0197] In some embodiments, refer to Figure 17 The spring-loaded latch 42 includes a housing 421. The housing 421 is mounted on the base plate 2. In some embodiments, the housing 421 is mounted on the cover plate 25.

[0198] In some embodiments, the spring-loaded latch 42 includes a claw 422. The claw 422 is installed inside the housing 421 and can retract or open under the action of an external force along the length of the housing 421.

[0199] Reference Figure 18 When the latch 422 opens, the spring-loaded body 41 ejects the latch 422, causing the cover plate 25 to eject from the assembly port 24. (Refer to...) Figure 19 When the pawl 422 retracts, the spring-loaded body 41 clamps the pawl 422, and the cover plate 25 is fixed at the assembly port 24.

[0200] In some embodiments, a spring-loaded latch 42 or a spring-loaded body 41 is mounted on the second mounting plate 32.

[0203] The air conditioner 100 proposed in this embodiment includes an indoor housing, which includes a top plate and a bottom plate 2 disposed opposite to each other along the height direction. The bottom plate 2 has an assembly opening 24, and a cover plate 25 is installed on the assembly opening 24. A filter assembly 51 is inserted into or pulled out of a first cavity 15 through the assembly opening 24.

By installing a push-button tactile switch on the base plate 2, the cover plate 25 can be opened by pressing the bottom 2, and the filter assembly 51 can be replaced, which effectively reduces the difficulty for users to replace the filter assembly 51, while ensuring the aesthetics and integrity of the base plate 2 of the air conditioner 100.

[0204] In some embodiments, the air conditioner 100 includes a TVOC gas detection device 5. (See reference...) Figure 2 The TVOC gas detection device 5 is installed at the indoor air inlet 11.

[0205] The mounting housing 421 of the TVOC gas detection device 5 has small holes on its surface to receive changes in indoor airflow.

[0206] The TVOC gas detection device 5 is designed with a mounting cover 25 on the back, and an opening on the back of the mounting cover 25 to allow indoor air to flow into the interior of the TVOC gas detection device 5 through the opening.

[0207] After the air conditioner is turned on, the indoor air inlet 11 draws in air and creates a negative pressure zone, causing airflow. Since the TVOC gas detection device 5 is close to the indoor air inlet 11, the air near it will also generate negative pressure flow, thereby causing air quality changes on the surface of the TVOC gas detection device 5, enabling the TVOC gas detection device 5 to receive external air quality signals.

[0208] In some embodiments, the TVOC gas detection device 5 is configured as a TVOC sensor.

[0209] In this application, a spring-loaded buckle and a spring-loaded body are respectively provided on the cover plate and the bottom plate. By lightly pressing, the spring-loaded buckle and the spring-loaded body are separated. When the cover plate pops open, the cover plate rotates and falls to open, thereby enabling the replacement of the filter assembly.

[0210] The air conditioner also includes a controller, which is used to send instructions to the air conditioner 100 to control the working process of the air conditioner 100.

[0211] The controller is used to coordinate the operation of the entire air conditioner 100. This includes receiving user commands, controlling the operation of various modes such as cooling mode, heating mode, fan mode, shutdown mode, and fresh air mode, as well as uploading the operating status of the air conditioner 100 to the cloud.

[0212] TVOC gas detection device 5 is installed at indoor air inlet 11 to receive real-time indoor air quality information.

[0213] The TVOC gas detection device 5 is assembled with a cover that has multiple small holes on the front. It is connected to the indoor air inlet 11 of the air conditioner with a snap fastener. It is set at the indoor air inlet 11 and can receive changes in indoor air quality most quickly when the air conditioner is turned on.

[0214] Setting the indoor air inlet 11 can be effectively applied to the scenario of pre-installed duct air conditioners. Unlike the scenario of living room air conditioners, pre-installed scenarios do not necessarily have a front panel. Therefore, if you want to use the TVOC gas detection device 5 in the scenario of pre-installed systems, the most reasonable design position is the indoor air inlet 11.

[0215] In this application, the TVOC gas detection device 5 is installed in the indoor air inlet 11. Compared with the related technology where the TVOC gas detection device 5 is installed in the online controller, the surrounding air flows faster, which can quickly receive changes in air quality, and the signal reception is fast and the detection device is sensitive.

[0216] The principle of the TVOC gas detection device 5 for detecting indoor air concentration is as follows: by periodically monitoring the resistance value of the TVOC sensitive element in the TVOC gas detection device 5, reading the resistance value in real time, and performing software filtering based on the resistance value, the indoor air concentration is obtained.

[0217] Reference Figure 20 This explains the control logic for gas detection in the TVOC gas detection device 5.

[0218] In some embodiments, the controller is configured to receive the indoor air concentration detected by the TVOC gas detection device 5 (S2001).

[0219] In some embodiments, an index value is obtained based on the indoor air concentration and a preset reference value using a first calculation logic (S2002).

[0220] In some embodiments, the average value of inde× within a first time period is obtained, and this average value is defined as the first average value (S2003).

[0221] In some embodiments, the average value of inde× within a second time period is obtained, and this average value is defined as the second average value (S2004).

[0222] The first time period is longer than the second time period, and the first and second time periods end at the same point on the timeline.

[0223] In some embodiments, when the first average value exceeds the second average value, the preset benchmark value is slowly reduced (S2005).

[0224] In some embodiments, when the second average value exceeds the first average value, the preset reference value is slowly increased (S2006).

[0225] In some embodiments, the system stops and changes the preset baseline value until the calculated index value is consistent with the average value of the index value in the second time period or the difference is within the preset difference range (S2007).

[0226] In the above steps, the execution order of S2003 and S2004 can be adjusted according to the settings.

[0227] In step S2007, when the difference between the calculated index value and the average value of the index value in the second time period is within a preset difference range, it is determined that the two are close and the stopping condition is met.

[0228] In the above, since the TVOC detection value is based on changes in indoor air quality, it can better adapt to changes in the environment, improving the reliability of the TVOC gas detection device 5. This also reduces user complaints caused by the display unit showing a red or yellow light for an extended period.

[0229] Reference Figure 24 This is an example diagram illustrating the change process of the index value in a certain scenario. It should be noted that the values ​​in the diagram are for illustrative purposes only and are not the required values ​​for the technical solution of this application.

[0230] Initially, the average index value over 24 hours is 200, and the average index value over 30 days is 150. At this point, the real-time detected index value is 300. Since the current average value over 24 hours is less than the average value over 30 days, the preset baseline value is slowly increased. The real-time index value then begins to decrease slowly at a rate of (300-200) / 10 = 10 / hour, which is (index value - average index value over 24 hours) ÷ 10 / hour.

[0231] After 10 hours, the real-time value is comparable to the average value over 24 hours. At this point, the value of the preset baseline is no longer changed.

[0232] This application allows for adjustment of preset benchmark values ​​for specific scenarios, thereby adjusting the output index value and influencing the level display of the air quality level. This avoids the situation where a single detection logic causes the level display to remain at the same level in high-concentration scenarios, failing to accurately reflect changes in indoor air quality, providing a poor user experience, and affecting product reliability.

[0233] The corresponding index value is calculated based on the actual air quality concentration in the user's home and a preset benchmark value. The preset benchmark value is then adjusted according to changes in air quality concentration to enhance the adaptability of the TVOC gas detection device 5 to changes in the indoor environment.

[0234] In some embodiments, the controller is configured such that the adjustment period of the preset reference value is a first period, the first period being calculated based on the average of the index value and the index value within a second time period using a second operational logic.

[0235] In this embodiment, by setting an adjustment period, sudden changes in the preset benchmark value are avoided, which could lead to sudden changes in the index value and result in inaccurate air quality level display.

[0236] In some embodiments, the first period is obtained by weighting the difference between the index value and the average index value within the second time period.

[0237] The weighting coefficients can be set as needed. Generally, the weighting coefficients are less than 1.

[0238] In some embodiments, the weighting factor is less than 1 / 3. This is used to weight the differences and prevent the preset benchmark value from changing too quickly.

[0239] In some embodiments, after the air conditioner is turned on for the first time, the average value of the indoor air concentration detected by the TVOC gas detection device 5 during the third time period after the first turn-on is obtained, and the average value is defined as the initial preset reference value.

[0240] In this embodiment, the initial preset baseline value is obtained by detecting the indoor air concentration within a certain period of time after the first power-on. The self-learning function can form a reliable detection value in the early stage, so that the changes in indoor air quality can be more reliably sensed in the future, thereby providing more reliable detection change values.

[0241] In this application, the TVOC gas detector 5 will activate its self-learning and self-adjusting index value function upon first use. The index value is adjusted based on the actual air quality concentration in the user's home. Through a long period of learning, a stable average air quality value is formed as the preset benchmark value for the index test. This ensures that the TVOC gas detector 5 can effectively detect changes in indoor polluted air concentration when encountering high concentration events, thereby improving the reliability of the TVOC gas detector 5 in air quality detection.

[0242] It should be noted that the above-mentioned indoor air concentration refers to the concentration of indoor TVOC gas.

[0243] Reference Figure 21 This describes one implementation method of gas detection using the TVOC gas detection device 5 in the embodiments of this application.

[0244] The TVOC gas detection device 5 (S2101) is turned on for the first time.

[0245] The controller receives the indoor air concentration (S2102) detected by the TVOC gas detection device 5;

[0246] Determine whether the TVOC gas detection device 5 has been turned on for the third time period (S2103);

[0247] In step S2103, if the target is reached, then step S2104 is executed to calculate the average value of the indoor air concentration detected by the TVOC gas detection device 5 during the third time period, and define the average value as a preset benchmark value.

[0248] The index value is obtained based on the indoor air concentration and the preset benchmark value using the first calculation logic (S2105).

[0249] Get the average of the index values ​​over 30 days and define this average as the first average (S2106).

[0250] Obtain the average value of the index over 24 hours and define this average value as the second average value (S2107).

[0251] Determine whether the first average value exceeds the second average value (S2108).

[0252] In step S2108, if the value exceeds the limit, step S2109 is executed to slowly reduce the preset reference value in a first cycle. The first cycle is calculated based on the average value of the index value and the index value within 24 hours.

[0253] Determine whether the current index value is consistent with the average index value in the last 24 hours (S2111);

[0254] If the values ​​match in step S2111, then step S2112 is executed to stop changing the preset reference value.

[0255] If there is a discrepancy in step S2111, then step S2109 is executed.

[0256] If the condition is not met in step S2103, then step S2103 is executed.

[0257] In step S2108, if the value does not exceed the threshold, then step S2110 is executed to slowly increase the preset reference value in a second cycle. The second cycle is calculated based on the index value and the average of the index values ​​over 24 hours.

[0258] Determine whether the current index value is calculated from the average index value of the last 24 hours (S2113).

[0259] If the results are consistent in step S2113, then step 2012 is executed.

[0260] If there is a discrepancy in step S2113, then step S2110 is executed.

[0261] In the above, whether the index value is consistent with the average index value over the past 24 hours is used as the condition for stopping the change of the preset baseline value. In some embodiments, it can also be determined whether the condition for stopping the change is met by judging whether the difference between the two meets a preset difference range.

[0262] In some embodiments, in the first calculation logic, the indoor air concentration detected by the TVOC gas detection device 5 is compared with a multiple of a preset reference value to obtain the corresponding index value.

[0263] In some embodiments, when the indoor air concentration detected by the TVOC gas detection device 5 exceeds a preset multiple of the baseline value, the index value is the product of the preset baseline value and the corresponding multiple.

[0264] For example, when the preset baseline value is calculated to be 150, the index value is 300 when the indoor air concentration exceeds twice the preset baseline value.

[0265] When the indoor air concentration exceeds three times the preset benchmark value, the index value is 350. The air quality level at this time is then calculated based on the index value.

[0266] Then, the air quality level is determined based on the preset threshold.

[0267] In some embodiments, the air conditioner includes a level display component. The level display component is used to display the indoor air quality level. The level displayed by the level display component corresponds to an air quality energy level.

[0268] In some embodiments, the level display component is electrically connected to the controller. The level display component is configured to display at least a first level and a second level based on the air quality concentration detected by the TVOC gas detection device 5. The first level represents an air quality that is superior to the air quality represented by the second level.

[0269] In some embodiments, when the calculated index value does not reach the first preset threshold X1, the level display component displays the first level.

[0270] In some embodiments, when the calculated index value exceeds a first preset threshold X1 but does not reach a second preset threshold X2, the level display component displays a second level.

[0271] The first preset threshold is less than the second preset threshold.

[0272] In some embodiments, the first preset threshold X1 is greater than zero, the range of (0, X1) is defined as the first range, [X1, X2) is defined as the second range, and [X2, ∞) is defined as the third range.

[0273] It is known that different ranges can be set to correspond to different air quality levels.

[0274] In some embodiments, the grade display component includes LED lights configured to display different colors according to different grades.

[0275] In some embodiments, the LED lights can display at least three different colors to represent different air quality levels. Different colors define different air quality levels.

[0276] For example, the LED lights are set to three colors: red, yellow, and green, corresponding to the third, second, and first levels, respectively. These levels are arranged from lowest to highest.

[0277] In some embodiments, the index value of the green light is in the range of (0, 200), the index value of the yellow light is in the range of [200, 400), and the index value of the red light is in the range of [400, ∞).

[0278] For example, when the preset baseline value is calculated to be 150, and the indoor air concentration exceeds twice the preset baseline value, the index value is 300. The level display component then displays a yellow light.

[0279] When the indoor air concentration exceeds three times the preset benchmark value, the index value is 450. The level display unit will then show a red light.

[0280] By setting up a level display component, the current indoor air quality can be displayed intuitively to the user without the need for terminal devices, reducing the difficulty for users to check indoor air quality.

[0281] In some embodiments, if the air conditioner stops before the third time period after the first power-on, the data before the stop is saved, and the indoor air concentration detected by the TVOC gas detection device 5 continues to be recorded the next time the unit is powered on, until the recording time reaches the third time period, at which point the level display component starts to display the level.

[0282] In some embodiments, the third time period needs to be greater than T1. If the third time period is too short, the obtained indoor air concentration cannot adequately characterize the indoor air quality; therefore, the third time period needs to be greater than T1.

[0283] In some embodiments, the third time period needs to be less than T2. ​​If the third time period is too long, the preparation time of the TVOC gas detection device 5 will be too long, resulting in excessively long waiting times for users. Furthermore, the indoor air quality may have changed over time, making it impossible to reflect subsequent indoor conditions. Therefore, the third time period needs to be less than T2.

[0284] In some embodiments, the third time period is set to 24 hours.

[0285] After the TVOC gas detector 5 has been in operation for 24 hours, it will begin broadcasting indoor air quality in real time, using a preset benchmark value as the detection basis. In the event of a high concentration of air pollution, it will provide an index value based on the multiple of the indoor air concentration relative to the benchmark.

[0286] In some embodiments, an index value is given based on the multiple of the deviation of the indoor air concentration from the baseline.

[0287] After the TVOC gas detection device 5 completes its self-learning during the third time period for the first time, it will continue to save the monitoring data. After the third time period, it will update the saved data from the most recent third time period.

[0288] Similarly, the TVOC gas detection device 5 will also include monitoring data within the first time period, and will update the saved data within the most recent first time period after the first time period has expired.

[0289] The TVOC gas detection device 5 will also include monitoring data within a second time period, and will update the saved data within the most recent second time period after the second time period has elapsed.

[0290] It should be noted that data can be stored in the TVOC gas detection device 5 or in the controller.

[0291] In some embodiments, the fresh air fan includes at least a first speed and a second speed, wherein the first speed is lower than the second speed.

[0292] In some embodiments, when the rating component displays the first rating, the fresh air fan operates at the first setting.

[0293] In some embodiments, when the rating component displays the second rating, the fresh air fan operates at the second setting.

[0294] In some embodiments, the fresh air fan also includes a third speed setting, which is greater than the second speed setting.

[0295] In some embodiments, when the level display shows the second fan, the fresh air fan operates at the second level. After operating for a period of time, if the level display still shows the second level, the fresh air fan is upgraded to the third level to increase the amount of outdoor air entering the room.

[0296] In some embodiments, the rating display component may also display a third rating, wherein the second rating represents air quality that is better than the air quality represented by the third rating.

[0297] In some embodiments, when the level display shows the third level, the fresh air fan operates at the third level; after operating for a period of time, when the level display shows the second level, the fresh air fan reduces to the second level.

[0298] Reference Figure 25 This is an example diagram illustrating the correspondence between the index value of the TVOC sensor after it is turned on and the level display component (here referring to the indicator light).

[0299] During the initial 24 hours, the TVOC sensor is turned on but does not output an index value, and the indicator light does not display anything during this time.

[0300] After 24 hours, the index value 150 will be output, at which point the corresponding traffic light color will be green.

[0301] After a period of time, the first high-concentration scenario was detected, and the index value gradually increased, exceeding 200, which is more than twice the average value within 24 hours (preset baseline value). At this time, the corresponding signal light color is yellow.

[0302] After a period of time, it was detected that a higher concentration scene had been entered, and the index continued to increase, exceeding 450, which is more than three times the average value (preset baseline value) within 24 hours. At this time, the corresponding signal light color is red.

[0303] Reference Figure 22 The control logic of a fresh air blower is illustrated using an example of a blower with three speed settings and a level display showing three levels. The level display shows the second level (S2201).

[0304] The fresh air ventilator is operating at the first speed setting (S2202);

[0305] Determine whether the set time has been reached (S2203);

[0306] In step S2203, if the condition is met, then step S2204 is executed to determine whether the level display component still displays the second level.

[0307] If the display still appears in step 2204, then step S2205 is executed, and the fresh air fan operates at the second speed.

[0308] If not displayed in step S2204, then proceed to step S2206, and the fresh air fan will automatically shut down.

[0309] If the condition is not met in step S2203, then step S2203 is executed.

[0310] In the above, TVOC and fresh air are linked for control. The quality of the air can be judged by the red, yellow and green light reaction detected by the TVOC gas detection device 5. The appropriate fresh air level is then automatically selected for the customer. Without increasing the indoor noise level and ensuring the customer's home experience, the indoor air is effectively exchanged and the indoor air quality is improved.

[0311] The TVOC gas detection device 5 detects a deterioration in air quality and, after issuing a signal, can automatically activate different levels of fresh air supply through control logic, thereby achieving efficient ventilation.

[0312] After the fresh air system has been running for a period of time, the air quality feedback improves, allowing users to better perceive the improvement in indoor air quality brought about by the fresh air system.

[0313] In some embodiments, the TVOC gas detection device 5 transmits three signal lights, namely "red," "yellow," and "green," to the user's remote control or mobile APP. Different signal lights represent different indoor air quality at this time, thereby informing the user of the current indoor air quality.

[0314] Reference Figure 26 In the TVOC and fresh air linkage mode, when the TVOC indicator light is yellow, the fresh air system automatically switches to low fan speed. If the yellow indicator light remains on for 5 minutes, the fresh air system automatically switches to medium fan speed. When the yellow light turns green, the fresh air system automatically shuts off.

[0315] When the TVOC indicator light is red, the fresh air system automatically switches to high fan speed; when the light changes from red to yellow, it switches to medium fan speed. (Reference) Figure 23 Taking a fresh air fan with three speed settings and a level display component showing the three levels as an example, we can illustrate another control logic of the fresh air fan.

[0316] The grade display component shows the third grade (S2301);

[0317] The fresh air ventilator is operating at the third speed setting (S2302);

[0318] Determine whether the level display component has dropped from level three to level two (S2303);

[0319] In step S2303, if the temperature drops to the second level, then step S2304 is executed, and the fresh air fan operates at the second speed.

[0320] Determine whether the level display component has dropped from level 2 to level 1 (S2306);

[0321] In step S2306, if the temperature drops to the first level, then step S2307 is executed, whereby the fresh air fan operates at the first level for a period of time and then is turned off or the fresh air fan is turned off directly.

[0322] In step S2306, if the level does not drop to the first level, then step S2306 is executed.

[0323] If the temperature does not drop to the second level in step S2303, then step S2305 is executed, and the fresh air fan remains in operation.

[0324] In step S2305, if the fresh air fan remains at the third speed for a period of time and the displayed speed level does not decrease, an alarm can be triggered to check whether there is a problem with the fresh air function of the air conditioner.

[0325] In step S2306, if the level display component does not drop to the first level, wait for a period of time. If, after a period of time, the level display component still does not drop or even rises to the third level, then increase the fresh air fan.

[0326] In step S2204, when the display level of the level display component is displayed as the second level or the third level, it is necessary to increase the operating level of the fresh air fan to improve the fresh air efficiency.

[0327] In the above steps, the detection results (air quality level) of the TVOC gas detection device 5 are linked to the operating status of the fresh air fan, so that the fresh air function can be automatically turned on when the air quality is poor, in order to improve the indoor air quality as soon as possible. At the same time, since the indoor air quality is detected in real time, the fresh air function can be turned on in a timely manner. In addition, when the problem is initially detected, the fresh air fan can operate at a lower fan speed, producing less noise, and can improve the indoor air quality as early as possible.

[0328] Meanwhile, if indoor air quality does not improve, further treatment can be achieved by increasing the speed of the fresh air fan.

[0329] The air conditioner proposed in this application embodiment includes a fresh air module disposed inside the outdoor casing or the indoor casing and a TVOC gas detection device 5 disposed in the indoor air inlet 11. The TVOC gas detection device 5 is used to detect the indoor air concentration.

[0330] The controller is configured to receive the indoor air concentration detected by the TVOC gas detection device 5; after the first power-on, it performs self-learning within a third time period to form a stable average air quality value as the preset benchmark value of the index.

[0331] After the initial self-learning upon startup, the index value can be obtained based on the indoor air concentration and preset benchmark values ​​using the first calculation logic.

[0332] In order to continuously enhance the adaptability of the TVOC gas detection device 5 to changes in the indoor environment, a long-term self-learning and self-adjustment logic will be activated after the third time period.

[0333] Get the average value of the index values ​​within the first time period, and define this average value as the first average value. Get the average value of the index values ​​within the second time period, and define this average value as the second average value. The first time period is longer than the second time period, and the first time period and the second time period have the same endpoint on the time axis.

[0334] When the first average value exceeds the second average value, the preset benchmark value is slowly decreased; when the second average value exceeds the first average value, the preset benchmark value is slowly increased until the calculated index value matches the average index value within the second time period or the difference is within the preset difference range, at which point the preset benchmark value is stopped. The corresponding index value is calculated based on the actual air quality concentration in the user's home and the preset benchmark value, and the preset benchmark value is adjusted according to changes in the actual air quality concentration in the user's home to enhance the adaptability of the TVOC gas detection device 5 to changes in the indoor environment.
