Detailed Description

Fig. 1 is a sectional view of a wall-mounted air conditioning indoor unit according to an embodiment of the present invention. Referring to fig. 1, the indoor unit of an air conditioner may generally include a frame for supporting a fan 170 and a heat exchanger 160, a casing 120 covering the frame 110, and a front panel 130 disposed at a front portion of the casing 120 to form a front surface of an indoor wall unit of the air conditioner. Specifically, the top of the casing 120 is provided with an air inlet grille 122, and an air inlet 121 is formed on the air inlet grille 122 to allow ambient air to enter the indoor unit of the air conditioner. The framework, the housing and the front panel can jointly form a casing of the indoor unit of the air conditioner.

Further, the wall-mounted unit of the air conditioner room further includes a purification assembly 150. The cleaning assembly 150 is configured to be controllably moved and to cover the intake vent 121 to clean air entering the cabinet through the intake vent 121. The heat exchanger 160 may be disposed inside the purification assembly 150 and configured to exchange heat with air flowing therethrough to form clean temperature-changed heat exchange air.

Specifically, the purge assembly 150 may be configured to be switched by the driving device between a purge position completely shielding the intake vent 121 and a non-purge position away from the intake vent 121.

That is, when the air quality is medium or poor, the purifying assembly 150 can move from the inner side of the front panel 130 to the inner side of the air inlet 121 under the driving of the driving device, the purifying assembly 150 completely shields the air inlet 121, the purifying assembly 150 is in full contact with the air, the air flow entering the indoor unit 100 is fully purified, and the air quality of the indoor environment is improved.

The cleaning assembly 150 is driven by the driving device to move from the inner side of the front panel 130 to the inner side of the air inlet 121 in the upward and backward directions, the whole surface of the cleaning assembly 150 completely covers the air inlet 121, and the airflow entering the indoor unit 100 needs to be fully cleaned by the cleaning assembly 150 and then enters the indoor unit 100.

When the air quality is good or excellent, the purification assembly 150 can be driven by the driving device to move from the inner side of the air inlet 121 to the inner side of the front panel 130, that is, to the position between the front panel 130 and the indoor heat exchanger 160, so that the air inlet 121 is exposed, the wind resistance of the purification assembly 150 can be reduced, and the air conditioner is more energy-saving and environment-friendly.

When the purifying assembly 150 is driven by the driving device to move from the inner side of the air inlet 121 to the inner side of the front panel 130 in the forward and downward directions, the whole purifying assembly 150 can completely move to the inner side of the front panel 130 to completely expose the air inlet 121, and the purifying assembly 150 does not generate resistance to the airflow entering the air inlet 121. The purifying assembly 150 can also be partially moved to the inner side of the front panel 130 to partially shield a portion of the air inlet 121, and partially expose and partially shield the portion of the air inlet 121, thereby reducing the wind resistance of the purifying assembly 150. Therefore, the flexibility and adjustability of the air purification capacity are realized, and the expansion and the flexibility of the use of the air conditioner are realized.

The vertical distance of the purge assembly 150 from the surface of the heat exchanger 160 is relatively close as the purge assembly 150 moves within the enclosure. Thus, when the cleaning assembly 150 moves to block a portion 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.

It was common in the art prior to the present invention to mitigate the problem of uneven heat exchange efficiency by reducing the overall frequency of the heat exchanger 160. However, this is at the expense of the cooling capacity of the wall-mounted unit in the air conditioner room, and the use effect of the user is seriously affected.

Fig. 2 is a schematic structural view of a heat exchanger according to an embodiment of the present invention. Referring to fig. 2, to solve the above problem, the heat exchanger 160 may be configured to have a plurality of heat exchange areas, and each of the two heat exchange areas has a refrigerant pipeline. Further, the air conditioner indoor wall-mounted unit further comprises a liquid separation adjusting device 70. The liquid separation adjusting device 70 is disposed at the upstream of the refrigerant input end of the heat exchanger, and two liquid separation outlets thereof are respectively communicated to the refrigerant pipelines of the two heat exchange areas, so as to distribute the amount of the refrigerant entering the refrigerant pipelines of the two heat exchange areas according to the position of the purification assembly 150.

The present invention creatively divides the heat exchanger 160 into a plurality of heat exchange areas, and adjusts the input amount of the refrigerant in each heat exchange area according to the difference of the air volume flowing through the plurality of heat exchange areas. Therefore, the whole wall-mounted unit of the air conditioner room is guaranteed to have high heat exchange efficiency, the phenomenon that the local temperature difference of the heat exchanger 160 is too large is avoided, the running stability of the heat exchanger 160 is enhanced, and better use experience is provided for users.

Specifically, the two heat exchange areas are a first heat exchange area located below the air inlet 121 and a second heat exchange area located below the front side of the front edge of the air inlet 121. The purification assembly 150 is configured to be controllably movable between a first position upstream of the air intake path of the first heat exchange area and a second position upstream of the air intake path of the second heat exchange area. The first position is a purification position where the purification assembly completely shields the air inlet, and the second position is a non-purification position where the purification assembly leaves the air inlet.

Fig. 3 is a schematic front view of a dispensing adjustment device 70 according to one embodiment of the present invention. Fig. 4 is a schematic cross-sectional view of a dispensing adjustment device 70 according to one embodiment of the present invention.

Referring to fig. 3, the liquid-separating adjusting device 70 has a flow-dividing chamber, and an elastic member 700 is disposed in the flow-dividing chamber to divide the inner space thereof into a first sub-chamber and a second sub-chamber, so as to respectively accommodate at least part of the refrigerant flowing into the flow-dividing chamber. Specifically, the liquid separation adjusting device 70 further includes a main diversion pipeline 200, a first diversion pipeline 210 and a second diversion pipeline 220, which are communicated with the refrigerant inlet thereof. The main diversion pipeline 200 is configured to guide the refrigerant into the diversion cavity. The first diversion pipeline 210 is configured to communicate with the first sub-chamber to guide the refrigerant in the first sub-chamber to flow out of the liquid separation regulating device 70. The second guiding pipe 220 is configured to communicate with the second sub-chamber to guide the refrigerant in the second sub-chamber to flow out of the liquid separation regulating device 70.

Further, the first guiding pipeline 210 is configured to communicate with the refrigerant receiving opening of the first heat exchanging region, so as to guide the refrigerant in the first sub-chamber to enter the first heat exchanging region. The second guiding pipeline 220 is configured to communicate with the refrigerant receiving port of the second heat exchange area to guide the refrigerant in the second sub-chamber to enter the second heat exchange area.

In some embodiments of the present invention, the elastic member 700 is composed of a fixed part 710 and a movable part 720. The fixing portion 710 is arc-shaped and is configured such that the outer peripheral end edge thereof is fixed to the inner wall of the branch chamber. The movable portion 720 is disposed such that a portion of its peripheral edge is connected to at least a portion of the inner peripheral edge of the fixed portion 710, and another portion of its peripheral edge is adjacent to at least a portion of the inner peripheral edge of the fixed portion 710 and/or a portion of the inner wall of the branch chamber, so as to separate the refrigerant in the first sub-chamber and the second sub-chamber and respectively deliver the refrigerant therein to the refrigerant pipes of the two heat exchange regions.

Referring to fig. 4, in some embodiments of the present invention, the elastic member 700 may be a sheet shape. The fixed part 710 and the movable part 720 may form a complete sectional shape having the same shape and size as at least one section of the distribution chamber to divide the inner space thereof into two parts.

That is, when the refrigeration effect of two heat transfer regions is similar, the heat transfer pressure of the two is also comparatively balanced to make respectively with the first subchamber of two heat transfer regional intercommunications and the fluid pressure of second subchamber roughly equal. From this, when the pressure in first subchamber and the second subchamber is equal, elastic component 700 can not receive rather than vertically effort, or this effort is far less than its self resilience force, thereby avoid movable part 720 and fixed part 710 or shunt intracavity wall between produce the clearance, and then prevent the indoor fluid exchange that produces of first subchamber and second subchamber, so that current comparatively balanced heat transfer effect can be maintained in two heat transfer regions, avoid its appearance of the too big condition of local difference in temperature, the stability of heat exchanger operation has been strengthened.

Further, a portion of the fixed portion 710 connected to the inner wall of the flow dividing chamber (hereinafter, referred to as a connecting portion) is away from the inlet of the flow dividing chamber for receiving the refrigerant, with respect to a portion of the movable portion 720 adjacent to at least a portion of the inner circumferential end edge of the fixed portion 710 and/or the inner wall of the flow dividing chamber (hereinafter, referred to as an adjacent portion).

Thus, when the pressures within the first and second sub-chambers are not equal, the pressure differential between the first and second sub-chambers causes the resilient sheet to be subjected to forces perpendicular thereto. When this effort is greater than the resilience force of elastic component 700 self, clearance is produced between movable part 720 and the reposition of redundant personnel intracavity wall, first sub-chamber and second sub-chamber intercommunication each other to produce the fluid exchange and get into the volume of the refrigerant in first sub-chamber and the second sub-chamber respectively.

When the purification assembly moves and switches between the purification position and the non-purification position, the wind resistance generated by the purification assembly to the two heat exchange areas is different, and then the heat exchange efficiency of the two heat exchange areas is different.

Specifically, when the purification assembly 150 is located at the upstream of the air inlet path of the first heat exchange region communicated with the first sub-chamber, the wind resistance of the first heat exchange region is increased, the heat exchange efficiency is reduced, and the temperature of the refrigerant therein is gradually lower than the temperature of the refrigerant in the second heat exchange region, so that the fluid pressure in the first heat exchange region is gradually lower than the fluid pressure in the second heat exchange region.

Accordingly, the fluid pressure within the first sub-chamber communicating with the first heat exchange region is progressively less than the fluid pressure within the second sub-chamber communicating with the second heat exchange region. When the effort that the fluid pressure difference of two subchambers produced was greater than the resilience force of elastic component 700 self, the one end atress that is located the adjacent part of moving part was crooked to the little first subchamber of fluid pressure to make the cross-sectional area that first subchamber is close to the refrigerant input of reposition of redundant personnel chamber reduce, and make the second subchamber be close to the cross-sectional area increase of the refrigerant input of reposition of redundant personnel chamber. From this, crooked movable part 720 can guide more relatively refrigerant to flow into the second subchamber to the refrigerant volume that the restriction flowed into in the first subchamber, thereby make the temperature difference and the heat transfer pressure difference of the first heat transfer region of intercommunication with the first subchamber and the second heat transfer region of intercommunication with the second subchamber reduce gradually, until the effort that the pressure difference of first subchamber and second subchamber produced is less than the resilience force of elastic component 700.

The air-conditioning indoor unit of the invention divides the refrigerant by arranging the liquid separation adjusting device 70 with the elastic part 700, so that when the heat exchange effect of each heat exchange area of the heat exchanger is obviously different, the elastic part 700 can automatically adjust the amount of the refrigerant entering each heat exchange area under the action of the pressure difference in the liquid separation cavity caused by the difference of the heat exchange effect, and no additional detection or monitoring device is needed, thereby simplifying the structure of the air-conditioning indoor unit and reducing the manufacturing cost thereof.

In some embodiments of the present invention, the heat exchanger 160 has a three-section housing, which includes a first heat exchange section 301 horizontally disposed below the air inlet 121, a second heat exchange section 302 extending downward from a front end of the first heat exchange section 301 to a front side, and a third heat exchange section 303 vertically extending downward from a lower end of the second heat exchange section 302. The first and second flow directing lines 210, 220 are both configured to tap into the shell from the second heat exchange section 302.

That is, the input ends of the first diversion pipeline 210 and the second diversion pipeline 220 can be connected to the second heat exchange section 302 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 diversion pipeline 210 and the second diversion pipeline 220 located inside the second heat exchange section 302 extend in opposite directions, so as to prevent the refrigerant in the respective branch pipelines of the two heat exchange areas from influencing each other.

In some embodiments of the present invention, the first heat exchange section 301 and at least a portion of the second heat exchange section 302 form a first heat exchange zone. The third heat exchange section 303 and at least a portion of the second heat exchange section 302 form a second heat exchange area. The first guiding pipe 210 is bent and extends upwards to the first heat exchange section 301 in the second heat exchange section 302 to cover the whole first heat exchange area. The second guiding pipe 220 is bent inside the second heat exchange section 302 and extends downwards to the third heat exchange section 303 to cover the whole second heat exchange area.

That is, the upper half of the second heat exchange section 302 belongs to the first heat exchange area, and the lower half of the second heat exchange section 302 belongs to the second heat exchange area. Thus, when the purification assembly 150 is positioned between the first position and the second position, the main effect on the heat exchanger 160 is substantially all located on the second heat exchange section 302 where the input ends of the first diversion conduit 210 and the second diversion conduit 220 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 guide pipeline 210 and the second guide pipeline 220 are arranged at the middle position of the heat exchanger 160, so that the bending adjustment amplitude of the movable piece can be reduced, the bending adjustment times of the movable piece can be reduced, and the service life of the movable piece can be prolonged.

In some embodiments of the invention, the heat exchanger further comprises an electronic expansion valve 161 arranged at the output of said second pilot line 220. 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 to respectively detect the first surface temperature of the first heat exchange area and the 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, in the operation process of the heat exchanger 160, the electronic expansion valve 161 can also be adjusted manually and controllably 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 the user is ensured.

Specifically, the temperature difference between the first surface temperature and the second surface temperature may be further set according to the performance of the heat exchanger 160, the operating state of the on-hook of the air conditioner room, 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.

In the indoor unit of the air conditioner, the purification component is driven by the driving device to move between a purification position which completely shields the air inlet of the indoor unit and a default position which is away from the air inlet, and when the purification function is not started, the purification component is positioned and moved out of the air inlet to reach a non-purification position; after the purification function is started, the purification component is driven by the driving device to move to a purification position which completely shields the air inlet of the indoor unit, and the air flow entering the indoor unit is purified.

Because above-mentioned purification subassembly is when purifying position and non-purification position, the windage that the indoor set fan produced the air current is obviously different, and after getting into purification mode, the air current filters, inevitably leads to the heat transfer effect decay through indoor set heat exchanger, appears the high load problem easily, can carry out corresponding control according to the operation mode of air conditioner, makes the air conditioner reduce the normal refrigeration or the influence of heating the function to the air conditioner when purifying.

For example, after entering the purification mode, a target tube temperature of the heat exchanger tube temperature of the indoor unit can be set, the heat exchanger tube temperature of the indoor unit is detected in real time, and the feedback control is performed on the refrigeration system of the air conditioner according to the 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 above-described refrigeration system may include a heat exchanger in the indoor unit, a compressor of the outdoor unit, and other necessary structures, and the refrigeration system may be applied to the following specific control modes.

When the air conditioner operates in a refrigerating mode, if the temperature of the heat exchanger pipe after purification is lower than the target pipe temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the fan of the indoor unit can be subjected to feedback control according to the difference, and the lower the temperature of the heat exchanger pipe is, the faster the fan rotating speed of the indoor unit is. If the increase of the rotating speed of the fan of the indoor unit can not 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 degree of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube can not 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 is prevented.

When the air conditioner performs heating operation, if the temperature of the heat exchanger pipe after purification is higher than the target pipe temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the fan of the indoor unit can be subjected to feedback control according to the difference, and the higher the temperature of the heat exchanger pipe is, the faster the fan rotating speed of the indoor unit is. If the increase of the rotating speed of the fan of the indoor unit can not 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 degree of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube can not 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 overhigh temperature of the heat exchanger of the indoor unit is prevented.
