Detailed Description

An embodiment of the present invention provides a wall-mounted type air conditioning indoor unit, fig. 1 is a schematic structural view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention, and fig. 2 is a schematic structural exploded view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention. An indoor unit 1 of a wall-mounted air conditioner of the present invention includes a casing 10 and at least one purification device 50 provided in the casing 10. The housing 10 has an inlet opening 11 for the inflow of an air flow and at least one outlet opening for the outflow of an air flow. Specifically, the cabinet 10 includes a front case 18 and a rear cover 19, and the intake vent 11 is formed on the rear cover 19. The wall-mounted type air conditioning indoor unit 1 supplies air to the front thereof, and thus, the air inlet 11 may be provided at the upper side or the rear side of the cabinet 10, and the air outlet may be provided at the front side or the lower side of the cabinet 10. The number of the air outlets can be one, two or more than two. Each of the purifying devices 50 is located on an airflow path from the air inlet 11 to a corresponding one of the air outlets to remove impurities from air flowing therethrough and purify the air. Specifically, the purifying device 50 can adsorb, decompose or otherwise remove nitrogen oxides, ozone and other harmful gases harmful to human health from the air flowing through it, so that the air flowing into the room is clean air. The number of the purification devices 50 may also be one, two, or more than two. The number of purification device 50 can be the same with the number of air outlets, and every air outlet all corresponds a purification device 50 to the air homoenergetic that makes to send out through every air outlet can be purified. In alternative embodiments, the number of purification devices 50 and the number of outlets may also be different.

Fig. 3 is a schematic front view of a purification module according to an embodiment of the present invention, and fig. 4 is a schematic cross-sectional view taken along a sectional line a-a in fig. 3. Referring to fig. 3 and 4, each purification apparatus 50 includes a core 51, and the core 51 has a plurality of through holes 511 for passing an air flow therethrough, each through hole 511 penetrating the core 51 obliquely downward in an air flow direction of an air flow path in which the purification apparatus is located. For example, when the airflow flowing direction of the airflow flowing path in which the purification apparatus is located is from the rear to the front, the through hole 511 thereof penetrates the core 51 obliquely downward from the rear to the front, that is, the through hole 511 thereof extends obliquely downward from the rear to the front. On one hand, the air supply direction of the indoor unit can be adjusted, so that the airflow is sent out by inclining a certain angle to the lower part of the front side, and better refrigerating experience and heating experience are realized; on the other hand, the length of the through-hole 511 is extended, and the contact time and the contact area of the air with the inner wall of the through-hole 511 are increased, thereby improving the purification effect of the purification apparatus 50.

Further, the plurality of through holes 511 are uniformly distributed on the core 51, the inner diameter of each through hole 511 is the same, and the inclination angles of the plurality of through holes 511 of the same core 51 are the same, so as to facilitate uniform air supply.

In some embodiments of the present invention, the purification apparatus 50 further includes a frame 52 for housing the core 51, and an inner side surface of the frame 52 and an inner wall of each through hole 511 are coated with a catalytic substance for accelerating decomposition of nitrogen oxides and ozone to increase a decomposition speed of nitrogen oxides and ozone, thereby improving a purification effect.

Further, the catalytic species may include both the first catalyst and the second catalyst. The first catalyst comprises a metal oxide for accelerating the decomposition of nitrogen oxidesExamples of this may include: TiO 2₂、WO₃Or V₂O₅And so on. The second catalyst comprises a manganese cerium or ferromanganese or manganese cobalt composite metal oxide for accelerating the ozone decomposition.

In some preferred embodiments, the first catalyst and the second catalyst are coated on the inner wall surfaces of the upstream section and the downstream section of the through-hole 511 in the direction of the internal airflow flow thereof, respectively, or the downstream section and the upstream section of the through-hole 511 in the direction of the internal airflow flow thereof, respectively. That is, the inner wall surface of the through-hole 511 may be divided into two sections, an upstream section upstream and a downstream section downstream in the flow direction of the gas flow therein, one of which is coated with the first catalyst and the other of which is coated with the second catalyst. In other words, the first catalyst and the second catalyst are coated at different positions on the inner wall of the through hole 511, respectively, so that on one hand, the mixing of the two catalysts can be prevented from generating unnecessary chemical reactions, and on the other hand, the nitrogen oxide and the ozone can be decomposed at the same time, thereby effectively removing the nitrogen oxide and the ozone.

Further, the flow direction of the gas flow on the gas flow path where the purification apparatus 50 is located is the thickness direction thereof. The thickness of the purifying device 50 is preferably 10mm-60mm, so that the purifying device 50 has a good purifying effect and is relatively thin, and the accommodating space inside the wall-mounted air conditioner indoor unit 1 is saved. In this embodiment, the thickness of the purification device 50 is preferably 40mm, and the portion with the thickness of 20mm on the side close to the air outlet is coated with the second catalyst on the inner wall of the through hole; the part with the thickness of 20mm on the side far away from the air outlet, and the inner wall of the through hole is coated with a first catalyst. That is, the purification apparatus 50 decomposes and removes nitrogen oxides first and then decomposes and removes ozone, which is an order advantageous to thoroughly remove two kinds of harmful gases, thereby thoroughly purifying air.

In some embodiments of the present invention, an angle α formed by each through hole 511 and a vertical plane and located below is an angle value ranging from 10 ° to 80 °, so that good cooling and heating experience can be achieved, and the problems of excessive noise and small air volume caused by excessive resistance of the purification device 50 to the air flow can be avoided.

In some embodiments of the present invention, the wall-mounted air conditioning indoor unit 1 further includes at least one ion wind generating device 30 for inducing at least a portion of the air introduced from the air inlet 11 to flow toward one or more of the at least one air outlet using an electric force. The ion wind generating device 30 can generate ion wind using electric field force, and the generation of the ion wind is based on the corona discharge principle. Due to the action of the high voltage, the electric field intensity near the needle electrode of the ion wind generating device 30 is extremely large, so that a large number of air molecules in the region are ionized. Under the action of an electric field, charged particles move directionally and collide with neutral particles without electricity in the movement process, and partial kinetic energy is transferred to the neutral particles, so that the neutral particles move directionally together, namely, ion wind is generated.

The present invention can replace at least part of the rotary air supply component (such as a fan) by driving the air supply by at least one ion wind generating device 30. Because the ion wind generating device 30 utilizes the electric field force to make the particles in the air obtain kinetic energy, so as to form ion wind, compared with a rotary air supply assembly, the ion wind generating device 30 has the advantages of small pressure loss, low energy consumption, low noise and the like, thereby greatly reducing the noise generated when the wall-mounted air conditioner indoor unit 1 operates. Meanwhile, since the ion wind generated by the ion wind generating device 30 is not generated by pressure but is a soft wind close to nature generated by an electric field force, the comfort level of the wall-mounted air conditioner indoor unit 1 can be improved.

The designer of the present invention, while providing the ion wind generating device 30, also recognizes that the ion wind is generated because the high voltage discharging device is provided inside the ion wind generating device 30During the operation of the generator 30, a certain amount of harmful gas (mainly O) is generated₃And nitrogen oxides). In order to prevent these harmful gases from being discharged, the present invention specifically designs the ion wind generating device 30 and the purifying device 50 as follows: the number of the ion wind generating devices 30 is the same as that of the purifying devices 50, and each ion wind generating device 30 is located at the upstream of a corresponding one of the purifying devices 50 in the flowing direction of the air flow in the casing 10 and is fixedly connected with the purifying device to form a whole which can be assembled and disassembled at the same time. Not only the assembling process of the wall-mounted air conditioner indoor unit 1 is simplified, the retention structure of the purification device 50 is omitted, the occupied space and the volume of the wall-mounted air conditioner indoor unit 1 are reduced, but also the harmful gas generated by each ion wind generating device 30 can be absorbed, so that the harmful substances such as nitrogen oxides, ozone and the like in the air supplied to the room can be more comprehensively removed, and the purification effect is further improved.

In some embodiments of the present invention, referring to fig. 1 and 2, the at least one air outlet 12 is disposed at a front side of the cabinet 10, and the air inlet 11 is disposed at a rear side or an upper side of the cabinet 10. The ion wind generation device 30 and the purification device 50 are each provided in one number, and the purification device 50 is provided directly in front of the ion wind generation device 30. The flow direction of the air flow in the cabinet 10 is from the rear to the front, and the through hole 511 of the purification apparatus 50 extends obliquely downward from the rear to the front, i.e., the front end opening of the through hole 511 is lower than the rear end opening thereof.

Further, the wall-mounted type air conditioning indoor unit 1 further includes a heat exchanging device 40 for exchanging heat with air flowing therethrough. The heat exchanging device 40 may be disposed at the rear side of the ion wind generating device 30 or at the front side of the purification device 50. Specifically, the heat exchanging device 40 may be a plate-shaped evaporator.

Fig. 5 is a schematic exploded view of a wall-mounted air conditioning indoor unit according to another embodiment of the present invention. In the embodiment shown in fig. 5, the number of the air outlets is plural, and includes two lateral air outlets 13 respectively disposed at two lateral sides of the casing 10 and facing the lateral front of the casing 10. Therefore, the wall-mounted air conditioner indoor unit 1 can respectively supply air towards the front of the transverse outer side of the casing 10, an encircling air supply effect is formed, the air supply range of the wall-mounted air conditioner indoor unit 1 is expanded, cold air or hot air is prevented from being directly blown to a human body, and the uniformity of indoor temperature is improved.

Further, the number of the ion wind generating devices 30 and the number of the purifying devices 50 are two, the two ion wind generating devices 30 are respectively arranged on the airflow flowing path from the air inlet 11 to the two lateral air outlets 13, and the two purifying devices 50 are respectively arranged outside the two ion wind generating devices 30. At this time, the airflow flow direction of the airflow flow path in which the two purification apparatuses 50 are located is from inside to outside, from the middle to both sides. Therefore, the through hole 511 of the purification apparatus 50 extends obliquely downward from inside to outside, i.e., the height of the inner side port of the through hole 511 close to the center of the cabinet 10 is higher than the height of the outer side port thereof far from the center of the cabinet 10.

In the embodiment shown in fig. 5, the air outlet further includes a bottom air outlet 14 disposed at the bottom of the casing 10 for supplying air to the front lower side of the wall-mounted indoor unit 1 of the air conditioner. The wall-mounted air-conditioning indoor unit 1 can be driven to supply air by the ion air generating device 30 alone or can be matched with the fan assembly 80 to drive air supply together. The ion wind generated by the ion wind generating device 30 can be sent out after heat exchange by the heat exchange device 40, or can be directly sent out without heat exchange by the heat exchange device 40, and can be sent out after independently supplying air or mixing with air flow driven by a fan assembly.

In some embodiments of the present invention, referring to fig. 1 and 2, at least part of the air outlets 12 are circular, each circular air outlet 12 is provided with an opening and closing mechanism 20 for rectifying the air supply, and each opening and closing mechanism 20 includes a central baffle 21 and a plurality of curved blades 22.

The central baffle 21 is fixedly disposed at the center of the corresponding one of the outlets 12, and an air outlet area is formed between the outer periphery of the central baffle and the inner periphery of the corresponding one of the outlets 12. For example, the central baffle 21 may be circular, and the corresponding outlet area is annular. In alternative embodiments of the present invention, the central baffle 21 may have other shapes such as a square shape, an oval shape, and the like.

The plurality of curved blades 22 are sequentially arranged along the circumferential direction of the central baffle 21, and the plurality of curved blades 22 are configured to be gathered toward the center of the central baffle 21 to at least partially open the wind outlet region, and to be fully gathered and contracted to the front side or the rear side of the central baffle 21. Therefore, when the wall-mounted air conditioner indoor unit 1 is shut down, the plurality of curved blades 22 are unfolded towards the edge of the air outlet 12, the air outlet area can be completely sealed, external dust and impurities can be effectively prevented from entering the air duct, and the working effect of the wall-mounted air conditioner indoor unit 1 is guaranteed. When the wall-mounted air conditioner indoor unit 1 works, the plurality of curved blades 22 gather and contract towards the center of the central baffle 21 to completely open the air outlet area, so that air can be supplied to the wall-mounted air conditioner indoor unit 1 conveniently.

Specifically, in some embodiments, the number of curved blades 22 may be 6 and are evenly disposed along the circumference of the central baffle 21. In other embodiments, the number of the blades may also be less than 6 or more than 6, and may be specifically set according to the size of the blades, the size of the central baffle 21, and the size of the air outlet 12. Preferably, the plurality of curved blades 22 can be completely gathered and contracted to the rear side of the central baffle 21, that is, when the plurality of curved blades 22 are in a completely gathered state, the central baffle 21 can shield the plurality of curved blades 22, and a user cannot observe the curved blades 22 from the outside of the air supply opening, so that the appearance of the air supply opening is more attractive. More importantly, the curved blades 22 can be completely folded to the rear side of the central baffle 21, so that additional air duct space is not occupied, and the space utilization rate inside the wall-mounted air conditioner indoor unit 1 is improved. The plurality of curved blades 22 may also be flared away from the center of the central baffle 21 to at least partially enclose the wind exit region. The plurality of curved blades 22 can be unfolded to completely cover the annular air outlet region, so that the air outlet can be completely closed.

Fig. 6 and 7 are schematic block diagrams of different orientations of curved blades of an opening and closing structure according to an embodiment of the present invention, respectively. In the present embodiment, the curved blade 22 is approximately crescent shaped, having an outer contoured edge portion that is convex and an inner contoured edge portion that is concave. The inner peripheral edge portion is disposed toward the center of the central baffle 21 when the plurality of curved blades 22 are gathered, and accordingly, the outer peripheral edge portion may be disposed toward the inner peripheral edge of the outlet 12 when the plurality of curved blades 22 are gathered. The outer and inner contoured edge portions together define the root and tip ends of the curved blade 22.

As shown in fig. 6-7, in some embodiments of the invention, the outer contoured edge portion of each curved blade 22 includes: a first circular arc shaped section 221 and a second circular arc shaped section 222. The inner contour edge portion includes: a third circular arc shaped section 223 and a fourth circular arc shaped section 224. The first and fourth circular arc-shaped

sections

221, 224 are progressively closer towards the root end of the curved blade 22, such that the root end of the curved blade 22 forms a tapered curved region. The second and third circular arc-shaped

sections

222, 223 are progressively closer towards the tip of the curved blade 22 so that the tip of the curved blade 22 also forms a tapered curved region. That is, the first circular arc-shaped section 221 and the fourth circular arc-shaped section 224 gradually approach in a direction toward the root end of the curved blade 22, so that the root end of the curved blade 22 forms a tapered curved region; the second arc-shaped section 222 and the third arc-shaped section 223 gradually approach in a direction directed toward the tip of the curved blade 22 so that the tip of the curved blade 22 forms a tapered curved region.

In some preferred embodiments of the present invention, the curvature of the first circular arc-shaped section 221 is equal to the curvature of the outer periphery of the central barrier 21. That is, when the plurality of curved blades 22 are completely gathered to the rear side of the central barrier 21, the first circular arc-shaped sections 221 of the plurality of curved blades 22 coincide with the outer peripheral edge of the central barrier 21. After the plurality of curved blades 22 are gathered, a partial region of each curved blade 22 is located between two adjacent curved blades 22 of the curved blade 22. The curvature of the second circular arc-shaped section 222 is equal to the curvature of the inner periphery of the air outlet 12. That is, when the plurality of curved blades 22 are fully unfolded to cover the wind outlet region, the second arc-shaped sections 222 of the plurality of curved blades 22 are overlapped with the inner periphery of the wind outlet 12. By such design, the plurality of curved blades 22 can be completely folded to the rear side of the central baffle 21 or completely unfolded to shield the air outlet region, so that the air outlet 12 has a more complete and beautiful appearance.

In addition, the curvature and length of the third circular arc shaped section 223 are both equal to the curvature and length of the first circular arc shaped section 221. In this embodiment, when the plurality of curved blades 22 are completely unfolded to cover the air outlet region, the first arc-shaped section 221 and the third arc-shaped section of each of the two adjacent curved blades 22 are just spliced together, so that the plurality of curved blades 22 can completely cover the air outlet region, and meanwhile, the adjacent curved blades 22 are not overlapped as much as possible, so that the size of the curved blades is fully utilized, and the appearance of the air outlet is more complete and attractive.

In some embodiments of the invention, to facilitate the gathering and unfolding of the plurality of curved blades 22, each curved blade 22 is preferably rotatably disposed about its root end to either the front or rear side of the central bezel 21. Moreover, after the plurality of curved blades 22 are gathered, a partial region of each curved blade 22 is located between two adjacent curved blades 22 of the curved blade.

Further, the first arc-shaped section 221 further has a guiding flange 225 that is gradually higher from the root end adjacent to the curved blade 22 to the direction away from the root end, so as to guide the curved blades 22 in the front-rear direction of the indoor unit when the curved blades 22 are contracted or expanded, so that the curved blades 22 can be at least partially overlapped. This is so because during the collapsing of the plurality of curved blades 22, there may be mechanical interference between adjacent curved blades 22. The guide flange 225 is located at a lower position near the root end and a higher position away from the root end, and when the adjacent curved blades 22 are folded to overlap each other, the guide flange 225 can guide the adjacent blades to slightly move toward the rear side so that the adjacent curved blades 22 are staggered in the front-rear direction of the opening and closing structure 20 to prevent mechanical interference.

In some embodiments of the present invention, referring to fig. 2, the number of the air outlets 12 provided with the opening and closing mechanism 50 is multiple, and the wall-mounted air conditioning indoor unit 1 further includes a plurality of axial fans 60 disposed in one-to-one correspondence with the air outlets 12 provided with the opening and closing mechanism 50. Specifically, the ion wind generating device 10 has one number, the axial flow fans 60 have two numbers, and the two axial flow fans 60 are respectively disposed on both lateral sides of the ion wind generating device 10.

In fig. 2, the positive direction of the X axis is directed to the front side of the wall-mounted indoor air conditioner, the positive direction of the Y axis is directed to the right side of the wall-mounted indoor air conditioner, and the positive direction of the Z axis is directed to the upper side of the wall-mounted indoor air conditioner. In the depth direction of the wall-mounted air conditioning indoor unit 1, an air guide structure 70 is disposed on the rear side of at least part of the air outlet 12. Preferably, an air guide mechanism 70 is provided at the outlet 12 having the opening and closing mechanism 20.

Fig. 8 is a front view schematically illustrating a wind guide structure of a wall-mounted air conditioning indoor unit according to an embodiment of the present invention. Referring to fig. 8, each wind guide structure 70 includes: a rotating ring 73 and two pendulum blade assemblies.

The rotating ring 73 is disposed inside the casing 10 and opposite to the corresponding one of the air outlets 12, and the rotating ring 73 is configured to controllably rotate around a central axis thereof. The inner circumferential edge of the rotating ring 73 may overlap with the inner circumferential edge of the outlet 12 in the vertical and horizontal directions of the wall-mounted air conditioning indoor unit 1, that is, the inner circumferential edge of the rotating ring 73 is disposed at the rear side of the inner circumferential edge of the outlet 12.

The two swing blade assemblies can be arranged on the rotating ring 73 at intervals, each swing blade assembly comprises a swing blade driving mechanism and a plurality of swing blades 74, the plurality of swing blades 74 are located on the inner side of the rotating ring, the root of each swing blade 74 is provided with a rotating shaft 741, and the tail end of each rotating shaft 741 can penetrate through a round hole. The swing blade driving mechanism is configured to drive the plurality of swing blades 74 to synchronously rotate around the respective rotation shafts 741. And the swing blades 74 of the two swing blade assemblies are also symmetrically arranged about the above-mentioned one diameter of the rotating ring 73, and the rotation shafts 741 of the two swing blades 74 which are symmetrical to each other are on the same straight line. The size of the flap 74 can be set according to the size of the air outlet area.

In some embodiments of the present invention, each of the pendulum drive mechanisms is rotatable following the rotation ring 73 and comprises: curved connecting rod, a plurality of rocker, crank and connecting rod motor.

In the present embodiment, the rotation range of the rotation ring 73 is preferably 0 to 90 °. The working principle of the air guiding structure 70 is as follows: the rotating ring 73 rotates to a preset position to drive the rotation shafts 741 of the plurality of swing blades 74 to move to a position at a specific angle relative to the horizontal plane, and then adjusts the rotation angle of the swing blades 74 according to the user's requirement. Specifically, when the user needs to wind the air conditioning indoor unit 1 up and down, the rotating ring 73 is rotated to 0 ° first. At this time, the rotation shaft 741 is in a horizontal position, as shown in the right air outlet 12 of the air-conditioning indoor unit 1 in fig. 6, and at this time, the two curved links are driven to move up and down, so as to turn the plurality of swing blades 74 up and down. When the swing blades 74 are turned upwards, the air outlet 12 blows air upwards; when the swing blades 74 are turned down, the air outlet 12 blows air downward. When the user needs to let air out from the indoor unit in the left-right direction, the rotating ring 73 is rotated to 90 degrees first. At this time, the rotation shaft 741 is in the vertical direction, as shown in fig. 6, and the left air outlet of the indoor unit 1 of the air conditioner drives the two curved links to move, so as to turn the plurality of swing blades 74 left and right. When the swing blades 74 are turned left, the air outlet 12 discharges air to the left; when the swing blades 74 are turned right, the air outlet 12 discharges air right.

Therefore, the swinging blade 74 of the air guiding structure 70 of the present invention can rotate around the rotation axis 741, and can also revolve around the center of the rotation ring 73 following the rotation ring. During the use of the indoor unit 1 of the air conditioner, a user can adjust the rotating ring 73 to rotate to determine the wind sweeping direction of the air inlet 12, such as up-down wind sweeping, left-right wind sweeping, and wind sweeping at an angle of 45 °, and then adjust the swinging vane 74 to rotate to sweep wind. Alternatively, while the rotary ring 73 is rotating, the wind sweeping is performed simultaneously to blow out the natural wind as much as possible. The swing blade 74 of the present invention has more various swing angles, and the user can more freely adjust the air supply angle of the air supply outlet.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
