During the movement of the connecting rod 146 with the arc-shaped rack 143, the positioning sliding column 146-1 slides in the hollow area, and at the same time drives the purification component 150 along the second guide rail 145-7 campaign.

As shown in Figures 14 and 15, the side of the base 144 facing the arc-shaped rack 143 can also be formed with an arc-shaped groove 144-4, and the side of the arc-shaped rack 143 close to the base 144 is provided with at least one second roller 143-3, the second roller 143-3 can be accommodated in the arc groove 144-4 and slidingly connected with the arc groove 144-4. Thus, the arc-shaped rack 143 can slide stably along the arc-shaped groove 144 - 4 , and the stability of the driving device 140 can be improved.

The side cover 145 away from the base 144 can be formed with a second guide rail 145-7, and the cleaning assembly 150 is driven by the connecting rod 146 to rotatably and slidably cooperate with the second guide rail 145-7, so as to cooperate with the non-cleaning mode in the purification mode. Switch between purification modes.

The motor 141 drives the arc rack 143 to slide along the arc groove 144-4 through the gear 142. During the sliding process of the arc rack 143, the connecting rod 146 slides with the arc rack 143, and between the arc rack 143 The relative movement of rotation is generated, and the purification assembly 150 is driven by the connecting rod 146 and moves along the second guide rail 145-7 along the path of the second guide rail 145-7, thereby realizing the conversion of the purification assembly 150 between the purification mode and the non-purification mode.

The second guide rail 145-7 may include a first arc segment 145-7-1 and a second arc segment 145-7-2 connected to the first arc segment 145-7-1, the first arc segment 145 - 7-1 and the second arc segment 145-7-2 have different arcs, that is to say, the degree of curvature of the first arc segment 145-7-1 and the second arc segment 145-7-2 is different, by This forms an irregularly shaped second guide rail 145-7 consistent with the movement path of the purification assembly 150. The first arc segment 145-7-1 can be located at the position corresponding to the frame of the lateral end of the casing 120 and the air inlet 121. The two arc segments 145 - 7 - 2 extend forward and downward to the inner side of the front panel 130 . The arc-shaped groove 144-4 can also extend to the inner side of the front panel 130, and the second arc-shaped segment 145-7-2 can be located outside the arc-shaped groove 144-4, that is to say, the same as the arc-shaped groove 144-4. The position of the second arc segment 145-7-2 is closer to the front panel 130 than that of .

Motor 141 drives gear 142 to rotate, and gear 142 drives arc rack 143 to slide in arc groove 144-4, and arc rack 143 is in sliding process, and connecting rod 146 slides with arc rack 143, and with arc Rotational relative motion is generated between the racks 143, and the cleaning assembly 150 is driven by the connecting rod 146 to move along the irregularly shaped second guide rail 145-7 between the position inside the front panel 130 and the position inside the air inlet 121 , so that the conversion of the purification assembly 150 between the purification mode and the non-purification mode is realized, and the movement path of the purification assembly 150 is located outside the arc-shaped groove 144-4.

Compared with the scheme of directly using the arc-shaped rack 143 to drive the purification assembly 150, and using the first guide rail 145-3 to provide a sliding track for the purification assembly 150, the connecting rod 146 drives the purification assembly 150 to cooperate with the irregularly shaped second guide rail 145-3. The movement of 7 takes up less space, which can save the interior space of the air conditioner indoor unit 100.

In order to facilitate a clear and intuitive understanding of using the arc-shaped rack 143 to drive the purification assembly 150, and using the first guide rail 145-3 to provide a sliding track for the purification assembly 150, the arc-shaped rack 143 drives the purification assembly 150 through the connecting rod 146. The different points of the motion scheme of the irregularly shaped second guide rail 145-7, the paths of the irregularly shaped second guide rail 145-7 and the arc-shaped first guide rail 145-3 are shown in FIG. 13 , as shown in FIG. As shown in 13, A is an irregular shape formed by connecting the first arc segment 145-7-1 and the second arc segment 145-7-2 with a different radian from the first arc segment 145-7-1 The path of the second guide rail 145-7, B is the path of the arc-shaped first guide rail 145-3, and the irregular-shaped second guide rail 145-7 is located outside the arc-shaped first guide rail 145-3.

Correspondingly, if the purification assembly 150 is directly driven by the arc-shaped rack 143 to move along the arc-shaped first guide rail 145-3, the movement track of the purification assembly 150 is located on the outside; if the purification assembly 150 is driven by the connecting rod 146, the purification assembly 150 The trajectory of motion should be on the inside. Therefore, the movement of the cleaning assembly 150 driven by the connecting rod 146 along the irregularly shaped second guide rail 145-7 requires less space, allowing more internal space of the indoor unit 100 without increasing the volume of the indoor unit 100. While arranging the driving device 140 and the purification assembly 150, sufficient space can also be provided for the arrangement of the heat exchanger 160, the blower 170 and other components.

As shown in FIGS. 1 , 2 , 6 , 8 , 9 and 14 , the purification assembly 150 can be detachably connected to the driving device 140 , which facilitates the cleaning and replacement of the purification assembly 150 .

The purification assembly 150 may include a bracket and a purification module 151 placed on the bracket. The shape and size of the purification module 151 can be determined according to the internal space of the indoor unit 100 and the size of the air inlet 121, for example, the purification module 151 can be arc-shaped.

Purification module 151 can comprise electrostatic adsorption module, plasma purification module, anion generation module and ceramic activated carbon device etc. that are arranged in sequence from outside to inside, electrostatic adsorption module, plasma purification module, anion generation module and ceramic activated carbon device all can be arc shape.

The electrostatic adsorption module can absorb charged PM2.5 particles, efficiently filter PM2.5 particles in the environment, and the plasma purification module can capture proprietary non-paired plasma, efficiently kill bacteria and viruses, and decompose into traces of H2O and CO2 into the air , The negative ion generating module can release negative ions into the air to form oxygen negative ions, efficiently remove dust and sterilize, purify the air, and activate air molecules at the same time, improve human lung function and promote metabolism.

The bracket may include two oppositely arranged connecting parts 152. In the scheme where the arc-shaped rack 143 directly drives the purification assembly 150 to slide along the arc-shaped guide rail, the two connecting parts 152 are directly connected to the corresponding arc-shaped rack 143; In the solution where the arc-shaped rack 143 drives the cleaning assembly 150 to move along the irregularly shaped second guide rail 145 - 7 through the connecting rod 146 , the two connecting parts 152 are rotationally connected to the corresponding connecting rod 146 . The purification module 151 is disposed on the connection part 152 and located between the two connection parts 152 .

There can be one purification module 151, and the two sides of the purification module 151 are respectively engaged in the slots of the corresponding connecting portion 152, and the two motors 141 respectively drive the corresponding gear 142 and the arc rack 143 to move synchronously, and the arc rack 143 can drive the two connecting parts 152 and the purification module 151 to slide along the arc-shaped first guide rail 145-3, so that the purification assembly 150 can be converted between the purification mode and the non-purification mode. When the purification assembly 150 is converted into the purification mode, the purification The entire surface of the module 151 completely covers the air inlet 121. The airflow entering the indoor unit 100 needs to be purified by the purification component 150 before entering the indoor unit 100; It directly enters the indoor unit 100 without being purified by the purification component 150 .

The two motors 141 respectively drive the gear 142 and the arc rack 143 to move synchronously. The arc rack 143 can drive the connecting rod 146 connected to it to slide and rotate, and the connecting rod 146 drives the purification component 150 connected to it to rotate along the irregular The shape of the second guide rail 145-7 moves so that the purification assembly 150 is switched between the purification mode and the non-purification mode. 100 airflow needs to be purified by the purification assembly 150 before entering the indoor unit 100; when the purification assembly 150 is switched to the non-purification mode, the purification module 151 moves out of the purification port 121, and the airflow directly enters the indoor unit 100 without being purified by the purification assembly 150.

There can be two purification modules 151, a cross bar 153 can be arranged between the connecting parts 152, the two ends of the cross bar 153 are respectively connected with the two connecting parts 152, and the middle position of the cross bar 153 can be provided with a joint part 154 to connect The two purification modules 151 , and the sides of the two purification modules 151 located at the joint portion 154 abut against each other.

The purification assembly 150 is driven by the drive device 140 to move between a position away from the air inlet 121 and the inside of the air inlet 121. When the purification function is not turned on, the purification assembly 150 is driven by the drive device to move out of the air inlet 121 and is in a non-purification position; After the purification function is turned on, the purification component 150 is driven by the driving device to move to completely cover the air inlet 121 and is in the purification position to purify the airflow entering the indoor unit 100 .

When the purification unit 150 is in the purification position and the non-purification position, the wind resistance of the airflow generated by the fan of the indoor unit is obviously different. After the purification function is turned on, the airflow is filtered, which will inevitably lead to the attenuation of the heat exchange effect of the heat exchanger 160, which is prone to high load According to the operating mode of the air conditioner, corresponding control can be carried out so that the air conditioner can reduce the impact on the normal cooling or heating function of the air conditioner during purification.

For example, after the purification function is turned on, the target tube temperature of the heat exchanger tube temperature of the indoor unit 100 can be set, and the heat exchanger tube temperature of the indoor unit 100 can be detected in real time, and the air conditioner can be adjusted according to the temperature difference between the detected tube temperature and the target tube temperature. Feedback control of the refrigeration system.

A specific control method is:

When the air conditioner is in cooling operation, if the tube temperature of the heat exchanger after purification is lower than the target tube temperature and does not exceed the first temperature difference threshold (for example, 3 degrees), the fan of the indoor unit 100 can be feedback-controlled according to the difference to exchange heat. The lower the pipe temperature, the faster the speed of the fan of the indoor unit 100 . If the increase in the fan speed of the indoor unit 100 cannot ensure that the heat exchanger tube temperature remains within the first temperature difference threshold with the target tube temperature, then increase the opening of the throttling device of the compression refrigeration cycle. When the temperature difference between the tube temperature and the target tube temperature is maintained within the second temperature difference threshold, the frequency of the compressor is reduced, so as to prevent the heat exchanger temperature of the indoor unit 100 from being too low and causing a high load.

When the air conditioner is in cooling operation, if the tube temperature of the heat exchanger after purification is higher than the target tube temperature and does not exceed the first temperature difference threshold (for example, 3 degrees), feedback control can be performed on the fan of the indoor unit 100 according to the difference. The higher the heat pipe temperature is, the faster the fan speed of the indoor unit 100 is. If the increase in the fan speed of the indoor unit 100 cannot ensure that the heat exchanger tube temperature remains within the first temperature difference threshold with the target tube temperature, then increase the opening of the throttling device of the compression refrigeration cycle. When the temperature difference between the tube temperature and the target tube temperature is maintained within the second temperature difference threshold, the frequency of the compressor is reduced, so as to prevent the heat exchanger temperature of the indoor unit 100 from being too high and causing a high load.

The first temperature difference threshold and the second temperature difference threshold can be configured according to the specifications and usage requirements of the heat exchanger of the indoor unit 100, for example, the first temperature difference threshold is set to plus or minus 3 degrees Celsius, and the second temperature difference threshold is set to plus or minus 5 degrees Celsius.

In addition, when the purification assembly 150 is driven by the driving device to switch between the purification mode and the non-purification mode, the vertical distance between the purification assembly 150 and the surface of the heat exchanger 160 is relatively short. Therefore, when the purification component 150 moves to cover a certain part of the heat exchanger 160, a relatively large wind resistance will be generated in this local area, which will affect the heat exchange efficiency of this local area. As a result, a local temperature difference occurs in the heat exchanger 160 , and problems such as condensation or freezing are prone to occur, thereby weakening its heat exchanging capacity.

Fig. 16 is a schematic structural diagram of a heat exchanger 160 according to an embodiment of the present invention.

To solve the above problems, in some optional embodiments of the present invention, the heat exchanger 160 has multiple heat exchange areas and at least one electronic expansion valve 161 , and is configured to adjust the opening of the electronic expansion valve 161 according to the position of the purification assembly 150 temperature to control the amount of refrigerant entering multiple heat transfer zones.

There may be a plurality of electronic expansion valves 161 . The specific number of electronic expansion valves 161 can be the same as the number of heat exchange areas, so that each heat exchange area has an electronic expansion valve 161 opposite to it, so that the electronic expansion valve 161 corresponding to it can be directly adjusted and controlled to enter The input amount of refrigerant therein is adapted to the heat exchange efficiency of each heat exchange area due to the difference in wind resistance, so that the heat exchange effect of each area of the heat exchanger 160 is approximately the same.

The number of multiple heat exchange areas is two, respectively the first heat exchange area located below the air inlet 121 and the second heat exchange area located below the front side of the front edge of the air inlet 121;

When the purification component 150 is driven by the driving device 140 to switch to the purification mode, the purification component 150 covers the air inlet, and the position of the purification component 150 at this time is the first position, and the downstream of the air intake path of the air inlet 121 is the first heat exchange area.

When the purification assembly 150 is driven by the driving device 140 to switch to the non-purification mode, the purification assembly 150 can move out of the air inlet 121 to expose the air inlet 121 . For example, the cleaning assembly 150 is driven by the driving device 140 to move from the position covering the air inlet 121 to the position inside the front panel. At this time, the position of the cleaning assembly 150 is the second position. At this time, the corresponding area inside the front panel is the second heat exchange area.

The heat exchanger 160 may have a main pipeline 162 for guiding the inflow of refrigerant, and a first distribution pipeline 163 and a second distribution pipeline 164 for respectively delivering the refrigerant to the first heat exchange area and the second heat exchange area. The electronic expansion valve 161 can be disposed at the input end of the first distribution pipeline 163 or the second distribution pipeline 164 to adjust the amount of refrigerant entering the first distribution pipeline 163 and/or the second distribution pipeline 164 .

When the cleaning assembly 150 is in the cleaning mode, the cleaning assembly 150 is driven by the driving device 140 to move to a position where the air inlet 121 is completely covered, so as to clean the air entering the indoor unit 100 . At this time, the first heat exchange area located inside the purification assembly 150 and below the air inlet 121 is significantly affected by the air resistance of the purification assembly 150 . Therefore, it is necessary to limit the refrigerant flowing into the first heat exchange area, and/or increase the refrigerant flowing into the second heat exchange area.

When the indoor ambient air quality is slightly better and the user does not require the purification component of the indoor unit 100 to start the purification mode, the purification component 150 is driven by the driving device 140 to move from the position that completely covers the air inlet 121 to the position inside the front panel, and does not interact with the ambient air. Locations where large areas are exposed to reduce or minimize contact with air. At this time, the second heat exchange area located on the rear side of the purification unit 150 and substantially perpendicular to the plane where the air inlet 121 is located is more obviously affected by the air resistance of the purification unit 150 . Therefore, it is necessary to limit the refrigerant flowing into the second heat exchange area, and/or increase the refrigerant flowing into the first heat exchange area.

That is, according to different moving positions of the purification component 150 , the heat exchanger 160 can be divided into different heat exchange areas accordingly. Furthermore, when the position of the purification component 150 changes, the indoor unit can directly adjust the refrigerant input volume of each heat exchange area immediately, so as to quickly balance the overall heat exchange effect of the heat exchanger 160, avoiding the heat exchange of the heat exchanger 160 There is a phenomenon of excessive local temperature difference.

In some optional embodiments, the number of electronic expansion valve 161 may be one. The electronic expansion valve 161 can be arranged at the input end of the second distribution pipeline 164, and is configured such that when the purification assembly 150 is driven by the driving device 140 to move to the position where the air inlet 121 is covered, the electronic expansion valve 161 increases its opening to first opening. That is, when the purification assembly 150 is located at the first position, its air resistance reduces the air flow passing through the first heat exchange area, thereby reducing the amount of refrigerant exchanged in the first heat exchange area. At this time, the opening degree of the electronic expansion valve 161 can be increased, so that the refrigerant flowing into the second heat exchange area increases, and the refrigerant flowing into the first heat exchange area decreases. Thus, the heat exchange pressure and heat exchange efficiency of the first heat exchange area and the second heat exchange area are adapted to the air volume flowing through them, so that the heat exchange effects of the two are balanced.

Correspondingly, when the purification assembly 150 is moved to the second position by the driving device 140 , the electronic expansion valve 161 reduces its opening degree to a second opening degree smaller than the first opening degree. That is to say, the air resistance of the purification assembly 150 at the second position reduces the air flow passing through the second heat exchange area, thereby reducing the heat transfer amount of the refrigerant in the second heat exchange area. At this time, the opening degree of the electronic expansion valve 161 can be reduced, so that the amount of refrigerant flowing into the second heat exchange area decreases and the amount of refrigerant flowing into the first heat exchange area increases. Thus, the heat exchange effects of the first heat exchange area and the second heat exchange area are balanced.

Specifically, since the first heat exchange area located below the air inlet 121 is more likely to be in contact with more ambient air than the second heat exchange area located at the front inside the casing, the heat exchange efficiency is relatively high. Therefore, the electronic expansion valve 161 can be directly arranged at the input end of the second distribution pipeline 164 that delivers refrigerant to the second heat exchange area, so that the input amount of refrigerant entering the second heat exchange area can be limited in advance to prevent or properly limit The heat exchange effect produced by the heat exchanger 160 may be unbalanced.

In some optional embodiments, the number of heat exchange regions of the heat exchanger 160 may also be other values greater than two. Correspondingly, the moving position of the purification component 150 can also be further subdivided. In this embodiment, the multiple moving positions of the purification assembly 150 may respectively correspond to multiple sets of ideal refrigerant input amounts for each heat exchange area. That is to say, in view of the various situations of uneven heat exchange efficiency that may occur in the heat exchanger 160, the corresponding refrigerant input volume split ratios are respectively set, so that the adjustment of the refrigerant input volume in each branch pipeline of the heat exchanger 160 More accurate and faster.

In this embodiment, the electronic expansion valve 161 is arranged at the input end of the second shunt pipeline 164 of the second heat exchange area, so that when the position of the purification assembly 150 changes, only a relatively small opening of the electronic expansion valve 161 is required. The temperature difference can balance the heat exchange pressures of the two heat exchange areas, thereby increasing the adjustment speed of the electronic expansion valve 161, making the adjustment range of the electronic expansion valve 161 more gentle and stable, and prolonging its service life.

Further, the specific values of the first opening degree and the second opening degree can be set according to the actual usage of the indoor unit. In some embodiments of the present invention, the first opening degree may be any opening degree value between 70% and 80%. For example, it may be 70%, 72%, 74%, 76%, 78%, or 80%. The second opening can be any opening value between 15% and 50%, for example, it can be 15%, 20%, 25%, 30%, 35%, 40%, 45% or 50%.

In some embodiments of the present invention, the heat exchanger 160 has a three-section shell, and the shell includes a first heat exchange section 165 horizontally arranged below the air inlet 121 , and the front end of the first heat exchange section 165 is forward. The second heat exchange section 166 extending below the side and the third heat exchange section 167 vertically extending downward from the lower end of the second heat exchange section 166 . Both the first distribution pipeline 163 and the second distribution pipeline 164 are configured to enter the casing from the second heat exchange section 166 .

That is, the input ends of the first branch line 163 and the second branch line 164 can be connected to the second heat exchange section 166 located in the middle of the heat exchanger 160 along the same extending direction. As a result, the mechanism of the refrigerant input pipeline is compact and occupies a small space. Further, the pipelines inside the second heat exchange section 166 of the first branch pipeline 163 and the second branch pipeline 164 respectively extend in opposite directions, so as to avoid refrigerant in the respective branch pipelines of the two heat exchange regions interdependent.

In some embodiments of the present invention, the first heat exchange section 165 and at least part of the second heat exchange section 166 form a first heat exchange area. The third heat exchange section 167 and at least part of the second heat exchange section 166 form a second heat exchange area. The first branch pipeline 163 bends in the second heat exchange section 166 and extends upward to the first heat exchange section 165 to cover the entire first heat exchange area. The second branch pipeline 164 bends in the second heat exchange section 166 and extends downward to the third heat exchange section 167 to cover the entire second heat exchange area.

That is, the upper half of the second heat exchange section 166 belongs to the first heat exchange area, and the lower half of the second heat exchange section 166 belongs to the second heat exchange area. Therefore, when the purification assembly 150 is located between the first position and the second position, its main influence on the heat exchanger 160 is basically located where the input ends of the first branch line 163 and the second branch line 164 are located. on the second heat exchange section 166. Therefore, the influence of the air resistance of the purification component 150 on the heat exchange effect of the first heat exchange area and the second heat exchange area is relatively similar. Therefore, setting the input ends of the first branch line 163 and the second branch line 164 at the middle position of the heat exchanger 160 can not only reduce the adjustment range of the opening degree of the electronic expansion valve 161, but also reduce its adjustment. The number of times makes the operation of the heat exchanger 160 more stable.

In some embodiments of the present invention, a first temperature sensor and a second temperature sensor (not shown in the figure) are respectively arranged on the outer surfaces of the first heat exchange area and the second heat exchange area, so as to respectively detect the temperature of the first heat exchange area. The first surface temperature of the hot zone and the second surface temperature of the second heat exchange zone. Further, the electronic expansion valve 161 can be configured such that when the difference between the first surface temperature and the second surface temperature is greater than a preset temperature difference, the electronic expansion valve 161 increases or decreases a preset opening value.

That is to say, the opening of the electronic expansion valve 161 can be adjusted immediately (increasing to the first opening or decreasing to the second opening) according to the moving position of the purification assembly 150 .
