Compared with the scheme that the movable end 150-2 of the purification assembly 150 is directly driven by the arc-shaped rack 143 and the first guide rail 145-3 is adopted to provide a sliding track for the movable end 150-2 of the purification assembly 150, the space occupied by the movement of the movable end 150-2 of the purification assembly 150 driven by the connecting rod 146 and the second guide rail 145-7 with the irregular shape is smaller, and the internal space of the indoor unit 100 of the air conditioner can be saved.
In order to clearly and intuitively understand the movable end 150-2 of the purifying assembly 150 driven by the arc-shaped rack 143 and to adopt the different points between the scheme that the first guide rail 145-3 provides a sliding track for the movable end 150-2 of the purifying assembly 150 and the scheme that the arc-shaped rack 143 drives the movable end 150-2 of the purifying assembly 150 to match the movement of the second guide rail 145-7 with an irregular shape through the connecting rod 146, fig. 13 shows the path of the second guide rail 145-7 with an irregular shape and the path of the first guide rail 145-3 with an arc shape, as shown in fig. 13, a is the path of the second guide rail 145-7 with an irregular shape formed by connecting the first arc-shaped section 145-7-1 and the second arc-shaped section 145-7-2 with an arc shape different from that of the first arc-7-1, B is the path of the first guide rail 145-3 with an arc shape, the irregularly shaped second guide rail 145-7 is positioned outside the first guide rail 145-3 having an arc shape.
Accordingly, if the movable end 150-2 of the purification assembly 150 is directly moved by the arc-shaped rack 143 along the first guide rail 145-3 having an arc shape, the moving path of the movable end 150-2 of the purification assembly 150 is located at the outer side, and if the movable end 150-2 of the purification assembly 150 is moved by the connecting rod 146, the moving path of the movable end 150-2 of the purification assembly 150 is located at the inner side. Therefore, the space required for the movable end 150-2 of the cleaning assembly 150 to move along the irregular-shaped second guide rail 145-7 by the connecting rod 146 is smaller, more internal space of the indoor unit 100 can be made, the size of the indoor unit 100 does not need to be increased, and sufficient space can be provided for the arrangement of the heat exchanger 160, the fan 170 and other components while the driving device 140 and the cleaning assembly 150 are arranged.
As shown in fig. 1, 2, 6, 8, 9 and 14, the movable end 150-2 of the purge assembly 150 can be detachably connected to the driving device 140, so as to facilitate cleaning and replacement of the purge assembly 150.
The purification assembly 150 can include a bracket and a purification module 151 disposed on the bracket. The shape and size of the purification module 151 may be determined according to the size of the air inlet 121 and the inner space of the indoor unit 100, and for example, the purification module 151 may have an arc shape.
Purification module 151 can include that static adsorption module, plasma purification module, anion generation module and ceramic activated carbon device etc. that set gradually from outer to inner, and static adsorption module, plasma purification module, anion generation module and ceramic activated carbon device all can be the arc form.

The bracket may include two connecting portions 152 disposed opposite to each other, a cross bar 153 may be disposed between the connecting portions 152, both ends of the cross bar 153 are connected to the two connecting portions 152, respectively, and the rear end of the purification module 151 abuts against the cross bar 153. In the scheme that 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 with the corresponding arc-shaped rack 143; in the scheme that the arc-shaped rack 143 drives the movable end 150-2 of the purifying assembly 150 to move along the second guide rail 145-7 with an irregular shape through the link 146, the two connecting parts 152 are rotatably connected with the corresponding link 146. The rear end of the purification module 151 is disposed on the connection part 152 and between the two connection parts 152. The front end of the purification module 151 may be directly fixed inside the front panel to constitute a fixed end 150-1 of the purification assembly 150. The rear end of the purification module 151 and the bracket together constitute the movable end 150-2 of the purification assembly 150.
Because the purification assembly 150 is in purification mode and non-purification mode, the windage that indoor set fan produced the air current is obviously different, after opening purification performance, the air current filters, must lead to the heat transfer effect attenuation through heat exchanger 160, appears high load problem easily, can carry out corresponding control according to the operational mode of air conditioner, makes the air conditioner reduce the influence to the normal refrigeration of air conditioner or heating function when purifying.
For example, after the purification function is turned on, a target tube temperature of the heat exchanger tube temperature of the indoor unit 100 may be set, the heat exchanger tube temperature of the indoor unit 100 may be detected in real time, and the refrigeration system of the air conditioner may be feedback-controlled according to a temperature difference between the detected tube temperature and the target tube temperature. The air conditioner to which the indoor unit of the present invention is applied further includes an outdoor unit, the cooling/heating system may include a heat exchanger in the indoor unit, a compressor of the outdoor unit, and other necessary structures, and the cooling/heating system may be applied to the following specific control manner.
When the air conditioner operates in a cooling mode, if the temperature of the heat exchanger tube after purification is lower than the target tube temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the fan of the indoor unit 100 can be subjected to feedback control according to the difference, and the lower the temperature of the heat exchanger tube is, the faster the fan rotating speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value with the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured to be maintained within the second temperature difference threshold value with the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the excessively low temperature of the heat exchanger of the indoor unit 100 is prevented.
When the air conditioner performs heating operation, if the temperature of the heat exchanger tube after purification is higher than the target tube temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the feedback control can be performed on the fan of the indoor unit 100 according to the difference, and the higher the temperature of the heat exchanger tube is, the faster the fan rotation speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value from the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured within the second temperature difference threshold value from the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the overhigh temperature of the heat exchanger of the indoor unit 100 is prevented.
The first temperature difference threshold and the second temperature difference threshold may be configured according to the specification and the use requirement 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 purge assembly 150 is driven by the driving means to switch between the purge mode and the non-purge mode, the vertical distance of the purge assembly 150 from the surface of the heat exchanger 160 is relatively short. Therefore, when the purifying assembly 150 shields a part of the heat exchanger 160, a relatively large wind resistance is generated in the local area, which affects the heat exchange efficiency of the local area. Therefore, the heat exchanger 160 generates local temperature difference, and the problems of condensation or freezing and the like are easy to occur, so that the heat exchange capability of the heat exchanger is weakened.
Fig. 16 is a schematic block diagram of a heat exchanger 160 according to an embodiment of the present invention.
To solve the above problem, in some alternative embodiments of the present invention, the heat exchanger 160 has a plurality of heat exchange areas and at least one electronic expansion valve 161, and is configured to adjust an opening degree of the electronic expansion valve 161 according to a position of the purification assembly 150 to control an amount of refrigerant entering the plurality of heat exchange areas.
The electronic expansion valve 161 may be plural. The specific number of the electronic expansion valves 161 may be the same as the number of the heat exchange areas, so that each heat exchange area has one electronic expansion valve 161 opposite to the electronic expansion valve, and the input amount of the refrigerant entering the heat exchange area can be directly adjusted and controlled by the corresponding electronic expansion valve 161, thereby adapting to the heat exchange efficiency of each heat exchange area, which is different due to different windage resistances, and further making the heat exchange effect of each area of the heat exchanger 160 substantially the same.
The number of the plurality of heat exchange areas is two, and the two heat exchange areas are respectively a first heat exchange area positioned below the air inlet 121 and a second heat exchange area positioned below the front side of the front edge of the air inlet 121;
when the purifying module 150 is driven by the driving device 140 to be converted into the purifying mode, the purifying module 150 shields the air inlet, at this time, the position of the purifying module 150 is the first position, and the downstream of the air inlet path of the air inlet 121 is the first heat exchanging area.
When the cleaning assembly 150 is driven by the driving device 140 to switch to the non-cleaning mode, the cleaning 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, and at this time, the position of the cleaning assembly 150 is the second position. At this time, the area corresponding to the inner side of the front panel is the second heat exchange area.
The heat exchanger 160 may have a main line 162 for guiding inflow of the refrigerant and first and second branch lines 163 and 164 for supplying the refrigerant to the first and second heat exchange regions, respectively. The electronic expansion valve 161 may be disposed at an input end of the first branch line 163 or the second branch line 164 to adjust an amount of the refrigerant entering the first branch line 163 and/or the second branch line 164.
In the cleaning module 150, in the cleaning mode, the cleaning module 150 is driven by the driving device 140 to move to a position completely shielding the air inlet 121, 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 wind resistance of the purification assembly 150. Thus, it is necessary to restrict the flow of the refrigerant into the first heat exchange region and/or to increase the flow of the refrigerant into the second heat exchange region.
When the indoor ambient air quality is slightly good and the user does not require the cleaning module of the indoor unit 100 to start the cleaning mode, the cleaning module 150 is driven by the driving device 140 to move from the position completely shielding the air inlet 121 to the position inside the front panel, and does not contact with the ambient air in a large area, so as to reduce or avoid the contact with the air as much as possible. At this time, the second heat exchange area located at the rear side of the purification assembly 150 and approximately perpendicular to the plane of the air inlet 121 is significantly affected by the wind resistance of the purification assembly 150. Thus, it is necessary to restrict the flow of the refrigerant into the second heat exchange region and/or to increase the flow of the refrigerant into the first heat exchange region.
That is, the heat exchanger 160 may be divided into different heat exchange areas according to different moving positions of the purification assembly 150. Further, when the position of the purification assembly 150 is changed, the indoor unit can immediately adjust the refrigerant input amount of each heat exchange area directly, so that the overall heat exchange effect of the heat exchanger 160 is rapidly balanced, and the phenomenon that the local temperature difference of the heat exchanger 160 is too large is avoided.
In some alternative embodiments, the number of electronic expansion valves 161 may be one. The electronic expansion valve 161 may be disposed at an input end of the second shunt line 164, and configured such that when the purge assembly 150 is driven by the driving device 140 to move to a position shielding the air inlet 121, the electronic expansion valve 161 increases its opening degree to a first opening degree. That is, when the purge assembly 150 is located at the first position, the air resistance thereof reduces the air flow passing through the first heat exchange area, thereby reducing the heat exchange amount of the refrigerant in the first heat exchange area. At this time, the electronic expansion valve 161 may increase the opening degree thereof so that the refrigerant flowing into the second heat exchange region is increased and the refrigerant flowing into the first heat exchange region is decreased. Therefore, the heat exchange pressure and the heat exchange efficiency of the first heat exchange area and the second heat exchange area are adaptive to the air volume flowing through the first heat exchange area and the second heat exchange area, and the heat exchange effects of the first heat exchange area and the second heat exchange area are balanced.
Accordingly, when the purge assembly 150 is moved to the second position by the driving device 140, the electronic expansion valve 161 decreases its opening degree to a second opening degree smaller than the first opening degree. That is, 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 exchange amount of the refrigerant in the second heat exchange area. At this time, the electronic expansion valve 161 may decrease the opening degree thereof so that the refrigerant flowing into the second heat exchange region decreases and the refrigerant flowing into the first heat exchange region increases. Therefore, the heat exchange effect of the first heat exchange area and the second heat exchange area is balanced.
Specifically, since the first heat exchange area located below the air inlet 121 is more likely to contact more ambient air than the second heat exchange area located at the front side inside the housing, the heat exchange efficiency is relatively high. Therefore, the electronic expansion valve 161 may be directly disposed at the input end of the second branch pipe 164 for delivering the refrigerant to the second heat exchange area, so as to pre-limit the input amount of the refrigerant entering the second heat exchange area, thereby preventing or properly limiting the imbalance of the heat exchange effect possibly generated by the heat exchanger 160.
In alternative embodiments, the number of heat exchange areas of the heat exchanger 160 may be other values greater than two. Accordingly, the movement position of the purge assembly 150 may be further subdivided. In this embodiment, the plurality of moving positions of the purification assembly 150 may respectively correspond to a plurality of sets of ideal refrigerant input amounts of each heat exchange area. That is, for the situation that the heat exchanger 160 may have various uneven heat exchange efficiencies, the corresponding refrigerant input amount distribution ratios are respectively set, so that the adjustment of the refrigerant input amount in each branch pipe of the heat exchanger 160 is more accurate and rapid.
This embodiment is through setting up electronic expansion valve 161 at the input of the second reposition of redundant personnel pipeline 164 of second heat transfer area for when the position of purification subassembly 150 changes, only need electronic expansion valve 161 to change a relative less opening difference can make the heat transfer pressure of two heat transfer areas obtain the equilibrium, thereby improved electronic expansion valve 161's governing speed, and make electronic expansion valve 161's regulation range more steady, prolonged its life.
Further, specific values of the first opening degree and the second opening degree can be set according to the actual use condition 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%, etc. The second opening degree may be any opening degree value between 15% and 50%, and may be 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, or the like, for example.
In some embodiments of the present invention, the heat exchanger 160 has a three-section housing including a first heat exchange section 165 horizontally disposed below the air intake 121, a second heat exchange section 166 extending from a front end of the first heat exchange section 165 to a lower front side, and a third heat exchange section 167 vertically extending downward from a lower end of the second heat exchange section 166. First and second tap lines 163, 164 are each configured to tap into the shell from second heat exchange section 166.
That is, the input ends of the first shunt line 163 and the second shunt line 164 can be connected to the second heat exchange section 166 located at the middle position of the heat exchanger 160 along the same extending direction. Therefore, the refrigerant input pipeline mechanism is compact and occupies small space. Further, the first branch pipe 163 and the second branch pipe 164 inside the second heat exchange section 166 extend in opposite directions, so that the refrigerant in the respective branch pipes of the two heat exchange areas can be prevented from influencing each other.
In some embodiments of the present invention, first heat exchange section 165 and at least a portion of second heat exchange section 166 form a first heat exchange zone. Third heat exchange section 167 and at least a portion of second heat exchange section 166 form a second heat exchange zone. First bypass line 163 bends within second heat exchange section 166 to extend upwardly to first heat exchange section 165 to cover the entire first heat exchange area. The second tap line 164 is bent within the second heat exchange section 166 down 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. Thus, when the purification assembly 150 is positioned between the first and second positions, the primary effect it has on the heat exchanger 160 is substantially all located on the second heat exchange section 166 where the input ends of the first and second shunt lines 163, 164 are located. Thereby making the windage of the cleaning assembly 150 have a similar effect on the heat exchange effect of the first heat exchange area and the second heat exchange area. Therefore, the input ends of the first shunt pipeline 163 and the second shunt pipeline 164 are both arranged at the middle position of the heat exchanger 160, so that the adjustment range of the opening degree of the electronic expansion valve 161 can be reduced, the adjustment times can be reduced, and the operation of the heat exchanger 160 is more stable.
In some embodiments of the present invention, a first temperature sensor and a second temperature sensor (not shown) are respectively disposed on outer surfaces of the first heat exchange area and the second heat exchange area to respectively detect a first surface temperature of the first heat exchange area and a second surface temperature of the second heat exchange area. Further, the electronic expansion valve 161 may be configured such that when the difference between the first surface temperature and the second surface temperature is greater than a predetermined temperature difference, the electronic expansion valve 161 increases or decreases a predetermined opening value.
That is, the opening degree of the electronic expansion valve 161 may be first adjusted (increased to the first opening degree or decreased to the second opening degree) instantaneously according to the movement position of the purge assembly 150. Then, in the operation process of the heat exchanger 160, the electronic expansion valve 161 can also perform real-time adjustment according to the first surface temperature and the second surface temperature of the first heat exchange area and the second heat exchange area, so that the heat exchange effect of each area of the heat exchanger 160 is continuously maintained at substantially the same level, and the use effect of a user is ensured.
Specifically, the temperature difference value of the first surface temperature and the second surface temperature may be further set according to the performance of the heat exchanger 160, the purification mode of the indoor unit, and the like. In some embodiments of the present invention, the temperature difference may be any temperature value between 0.5 and 2 ℃. For example, the temperature may be 0.5 ℃, 0.7 ℃, 0.9 ℃, 1 ℃, 1.5 ℃, 2 ℃ or the like. In some preferred embodiments, the temperature difference may preferably be 1 ℃, so as to ensure that the surface temperatures of the regions of the heat exchanger 160 do not differ too much, and avoid too frequent adjustment of the opening degree of the electronic expansion valve 161.
In some embodiments of the present invention, in the event that the difference between the first surface temperature and the second surface temperature is greater than the temperature difference, the electronic expansion valve 161 is configured to: when the first surface temperature is less than the second surface temperature, the electronic expansion valve 161 increases the opening value. When the first surface temperature is greater than the second surface temperature, the electronic expansion valve 161 decreases the opening value. Specifically, the preset opening degree adjusting value can be any value between 1% and 10%. For example, it may be 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, or the like.
That is, after the opening degree of the electronic expansion valve 161 is primarily adjusted according to the moving position of the purification assembly 150, in the operation process of the heat exchanger 160, the heat exchange effect of the first heat exchange area and the second heat exchange area may be slightly different due to the influence of factors such as the indoor environment where the wall-mounted air conditioner is located, and the surface temperature of the heat exchanger is unbalanced. At this time, the opening degree of the electronic expansion valve 161 is adjusted to a small extent according to the surface temperature difference of each heat exchange area of the heat exchanger 160, so that the input amount of the cooling medium in the heat exchanger 160 can be regulated in real time, and the local temperature difference on the heat exchanger 160 can be eliminated rapidly. In particular, the fine adjustment can also provide data support for the preset opening value required when the first opening, the second opening and the like are optimized and adjusted for the first time, and the fine adjustment is greatly beneficial to the functional perfection of the wall-mounted unit in the air conditioner room.
