Description
Technical Field
The present invention relates to an air conditioning apparatus, and more particularly, to an air conditioning indoor unit having an ion purification function and an air conditioner including the same.
Background
In an air conditioner as an air conditioning apparatus, with the expansion of a user group and the continuous improvement of quality of life, the demand of the user group for the air conditioner is no longer satisfied only with a limited function of adjusting the temperature and humidity of air. In addition, an increasing population of users is beginning to be aware of potential health problems caused by the quality of indoor air, and thus, purification of indoor air is also becoming a high-attention problem.
In recent years, various researches have been made in the field of air conditioning apparatuses, around how to achieve purification of indoor air. In an air conditioning indoor unit of an existing air conditioner, sterilization and deodorization are commonly realized by physical adsorption of activated carbon and the like. However, such a physical adsorption method is not only short in consumable life, but also needs to be replaced for 3 to 6 months, and in order to make the air (air outlet) blown into the room clean, it is generally only possible to provide a physical adsorption member at the effective area of the air outlet of the indoor unit main body of the air conditioning indoor unit, and the sterilization and deodorization speed is slow, and the sterilization and deodorization effect is also greatly affected by the adsorption capacity of the physical adsorption member. In addition, when the wind (intake air) entering the air conditioning indoor unit passes through the physical adsorption member containing the adsorption material such as activated carbon, the wind resistance is large, and not only the amount of the wind is affected, but also the power and noise of the air conditioning indoor unit are increased.
Therefore, how to continuously and efficiently purify the air to be blown into the room without frequently replacing consumables and without the air volume of the air outlet being affected basically becomes a technical problem to be solved.
In addition, a novel ion purification technology is known, in which dust and particles in the air are settled by generating negative ions by an ion generating module, and bacteria, viruses, mold and the like floating in the air are sterilized and disinfected.
However, there is no way to upgrade and improve the old air conditioner indoor unit held in the market, and there is a need for a consumer to replace a new air conditioner indoor unit, which increases the cost. Meanwhile, the existing used old air conditioner indoor unit is abandoned under the condition that the conventional service life is not achieved, and resource waste and economic loss of consumers are caused. On the other hand, old air conditioners for sale by manufacturers and sellers are also accelerated to be eliminated or sold at a reduced price, so that economic losses of the manufacturers and sellers are caused.
Therefore, how to apply the novel ion purification technology at low cost without replacing the existing indoor unit of the air conditioner is another technical problem to be solved urgently.

The ion generation module used in the air conditioning indoor unit 100 according to the embodiment of the present invention is not limited to the ion generation module 140 having the ion generation portion 142 protruding from the module main body 141 shown in fig. 2A and 2B, and other types of ion generation modules, such as the ion generator 140A shown in fig. 3, may be used.

In addition, in this version of the ionizer 140A, the ion ejection opening 143A is flush with the outer edge of the module body 141A.
(connection Structure 150)
Next, with reference to fig. 4 to 8, examples of the connection structure used in the air conditioning indoor unit 100 according to the embodiment of the present invention will be described.
("H" shaped mounting plate 150A embodiment)
Fig. 4-8 illustrate one embodiment of a connection structure 150 that is an "H" shaped mounting plate 150A.
The "H" -shaped mounting plate 150A shown in fig. 4 is approximately "H" -shaped overall, and is formed with a module mounting portion 151A in which the module bodies 141, 141A of the ion generating modules 140, 140A are mounted or fixed in the "—" portion of the "H" -shape, and flange portions 152A, 152A as the "|" portion of the "H" -shape are integrally formed at both ends of the "-" portion. As an example, as shown in fig. 5, fixing holes 153A, 153A may be formed in the burring portions 152A, and the H-shaped mounting plate 150A may be attached to a circumferential flange portion 111d provided on the casing 111 of the indoor unit main body 110 by a fastener such as a bolt, for example, to fix the H-shaped mounting plate 150A to the casing 111 of the indoor unit main body 110. In addition, the flange portions 152A, which are the "H" -shaped portions, may be fixed to the circumferential flange portion 111d by an adhesive method to fix the "H" -shaped mounting plate 150A to the casing 111 of the indoor unit main body 110.
Fig. 6 shows a case where the ion generating module mounted on the "H" -shaped mounting plate shown in fig. 4 is mounted and fixed to the indoor unit main body of the air conditioning indoor unit according to the embodiment of the present invention, wherein, as can be seen from fig. 1, the "H" -shaped mounting plate 150A on which the ion generating modules 140, 140A are mounted or fixed is arranged such that the "—" portion of the "H" -shaped mounting plate 150A, that is, the module mounting portion 151A is vertical with respect to the left-right direction, and the "|" portion of the "H" -shaped mounting plate 150A, that is, the burring portions 152A, 152A are flush with the circumferential flange portions 111d provided on the upper side and the lower side of the casing 111 of the indoor unit main body 110.
The ion generating modules 140 and 140A are mounted or fixed to the "-" portion of the "H" -shaped mounting plate 150A, that is, the module mounting portion 151A, and are provided on the outer wall surface of the machine chamber 110b on the side of the air outlet 111b (for example, the right side) outside the indoor unit main body 110 (that is, the downstream side of the air outlet section 110A2 of the indoor unit main body 110), and as shown in fig. 1, the ion generating sections 142 and 142A of the ion generating modules 140 and 140A are made flush with the edge (for example, the right edge) on the side of the air outlet 111b in the width direction.
The module bodies 141, 141A of the ion generating modules 140, 140A may be fixed to the "-" portion of the "H" -shaped mounting plate 150A, i.e., the module mounting portion 151A, by a fastener such as a bolt, or may be attached to the "-" portion of the "H" -shaped mounting plate 150A, i.e., the module mounting portion 151A, by another means (e.g., by an adhesive means).
Preferably, the ion generating portions 142, 142A of the ion generating modules 140, 140A are located near the large air volume region outside the air outlet 111 b.
The "large air volume region" referred to in the present invention means a region in which the air volume is significantly larger than that of other regions (i.e., small air volume regions) in the air outlet passage of the air blown out from the air outlet 111 b. The "large air volume region" includes a region where the air volume is maximum, and includes a case where the region is not the region where the air volume is maximum but is slightly smaller than the region where the air volume is maximum.
Specifically, as shown in fig. 6, the large air volume area is, for example, a position of a side edge of the drain pan 114. The air that passes through the indoor heat exchanger 113 and is blown to the vicinity of the drain pan 114 is blown obliquely upward by the side edge of the drain pan 114 having a tilted structure, and thus the side edge of the drain pan 114 is set to a large air volume region, or even a region where the air volume is maximum. By positioning the ion generating portion 142 of the ion generating module 140 near the side edge of the drain pan 114, the ion generating portion 142 in the air outlet region extending from the right side to the left outside the air outlet 111b generates negative ions after being energized, and the generated negative ions can be present in a large amount at a large air volume region (or region of maximum air volume) of the blow-out duct, whereby a large amount of negative ions are present at the large air volume region (or region of maximum air volume), dust and ions in the air can be removed to a large extent, and sterilization and disinfection can also be effectively performed.
The large air volume area includes a position located downward in the middle of the air outlet 111b in the height direction, in addition to the position of the side edge of the drain pan 114.
In this way, the ion generating portions 142 and 142A extending from the right side to the left side to the outside of the air outlet 111b generate negative ions after being energized, and the generated negative ions can be present in a large air volume area of the blow-out duct, whereby a large amount of negative ions exist in the large air volume area, and dust and ions in the air can be removed to a large extent, and sterilization and disinfection can be performed effectively.
The arrangement positions of the ion generating modules 140 and 140A are not limited to the positions where the ion generating portions 142 and 142A of the ion generating modules 140 and 140A are flush with the right edge of the air outlet 111b, and a part of the ion generating modules 140 and 140A (for example, only the ion generating portions 142 and 142A) may be protruded to the downstream side of the air outlet section 110A2 of the indoor unit main body 110 (i.e., inside the heat exchange chamber 110A).
The ion generating parts 142, 142A whose outermost ends are flush with the edge (upper edge or right edge) of the air outlet 111b generate negative ions after being energized, and the generated negative ions can enter the air outlet area outside the air outlet 111b under the action of kinetic energy generated by emission (downward or leftward), so that the generated negative ions can remove dust and particles in the air as well, and can sterilize and disinfect.
However, since the ion generating portions 142 and 142A do not extend into the air outlet region outside the air outlet 111b and the outermost ends are flush with the edge (upper edge or right edge) of the air outlet 111b, there is a possibility that negative ions generated from the ion generating portions 142 and 142A are adsorbed to, for example, the metal casing 111 (i.e., the outer wall surface of the machine room 110 b) and/or the metal "H" -shaped mounting plate 150A and/or the module body 141 of the indoor unit body 110, so that some negative ions are lost. In order to reduce or even avoid such loss of generated negative ions, it is preferable that at least the "-" portion of the metal material "H" shaped mounting plate 150A, i.e., the module mounting portion 151A and/or the module body 141, of the housing 111 of the indoor unit main body 110, which is close to the ion generating portions 142, 142A, is coated with a coating capable of preventing adsorption of negative ions. In addition, when other design conditions are satisfied, the housing 111 of the indoor unit main body 110 and/or the H-shaped mounting plate 150A and/or the module main body 141 may be made of a material other than a metal material, for example, a resin or the like, which can prevent negative ion adsorption. In this way, the loss of negative ions due to the adsorption of negative ions to the metal housing 111 and/or the H-shaped mounting plate 150A and/or the module body 141 can be prevented.
(example of hanging 150B)
Fig. 7 and 8 illustrate one embodiment of a connection structure 150, which is a sling 150B.
The hoist 150B shown in fig. 7 has a module mounting portion 151B in a flat plate shape, for example, to which the module bodies 141, 141A of the ion generating modules 140, 140A are mounted or fixed, a burring 152B (fixing portion) bent inward is formed at an upper end of the module mounting portion 151B of the hoist 150B, and first fixing holes 153B, 153B are formed in the burring 152B bent inward at an upper end. In addition, a hooking portion 154B turned out is formed at an upper end of the module mounting portion 151B of the hanging piece 150B. Further, a protruding piece 155B (fixing portion) protruding toward one side (right side) in the width direction is provided at one end (right end in fig. 7) of the module mounting portion 151B of the hanging piece 150B, and a second fixing hole 156B is formed in the protruding piece 155B located at the one side (right side) in the width direction.
The hooking portion 154B allows the hanging tool 150B to be hooked to the circumferential flange portion 111d on the upper side of the casing 111 of the indoor unit main body 110, and the hanging tool 150B to be firmly fixed to the circumferential flange portion 111d and the outer wall surface of the casing 111 of the indoor unit main body 110 in both directions by passing fasteners such as bolts through the first fixing holes 153B, 153B and the second fixing hole 156B.
In addition, the hanging member 150B may be firmly fixed to the circumferential flange portion 111d and the outer wall surface of the casing 111 of the indoor unit main body 110 in two directions by an adhesive method, instead of forming the first fixing holes 153B and/or the second fixing hole 156B.
The hooking portion 154B is formed in a folded shape, for example, but may be formed in any other suitable shape. The module attaching portion 151B of the hanging member 150B to which the ion generating modules 140, 140A are fixed can be hung on the wall surface of the indoor unit main body 110 of the air conditioning indoor unit 100 outside the casing 111 at a position above the air outlet 111B, more specifically, for example, above the right side in the air outlet 111B by hooking the hooking portion 154B to the circumferential flange portion 111d on the upper side of the casing 111 of the indoor unit main body 110, and the ion generating portions 142, 142A of the ion generating modules 140, 140A are positioned on the downstream side of the air outlet section 110A2 of the indoor unit main body 110. Thus, since the hanging piece 150B is disposed such that the module bodies 141, 141A of the ion generating modules 140, 140A mounted thereon are located in the small air volume region, and the module body ion generating portions 142, 142A of the ion generating modules 140, 140A are projected to the vicinity of the "large air volume region", it is possible to reduce the influence of the wind resistance in the blowing passage of the air by the module bodies 141, 141A of the ion generating modules 140, 140A and the module mounting portion 151B of the hanging piece 150B.
The module bodies 141, 141A of the ion generating modules 140, 140A may be fixed to the module mounting portion 151B of the hoist 150B in a plate shape, for example, by a fastener such as a bolt, as shown in fig. 8, or may be attached to the module mounting portion 151B of the hoist 150B in a plate shape, for example, by other means (for example, by adhesion).
As one example, the module bodies 141, 141A of the ion generating modules 140, 140A are laterally mounted on the module mounting portion 151B of the hoist 150B such that the ion generating portions 142, 142A of the ion generating modules 140, 140A are directed to one side in the left-right direction (width direction), for example, the left side. In addition, the module bodies 141, 141A of the ion generating modules 140, 140A may be also longitudinally mounted on the module mounting portion 151B of the hoist 150B such that the ion generating portions 142, 142A of the ion generating modules 140, 140A are directed downward.
In addition, it is desirable that the ion generating modules 140, 140A are disposed such that a portion of the ion generating modules 140, 140A (e.g., only the ion generating portions 142, 142A) protrude from the side edge or the lower edge of the module mounting portion 151B of the hoist 150B, but not limited thereto, and as shown in fig. 8, the ion generating modules 140, 140A may be disposed such that the outermost ends of the ion generating portions 142, 142A of the ion generating modules 140, 140A are flush with the side edge or the lower edge of the module mounting portion 151B of the hoist 150B.
At this time, since the outermost ends of the ion generating parts 142, 142A are flush with the side edges or the lower edges of the module mounting portions 151B of the hanging member 150B, there is a possibility that negative ions generated from the ion generating parts 142, 142A are adsorbed on the module mounting portions 151B and/or the module main bodies 141, 141A of the hanging member 150B, for example, made of a metal material, so that a part of the negative ions are lost. In order to reduce or even avoid such loss of generated negative ions, it is desirable to coat the module mounting portion 151B and/or the module bodies 141, 141A of the hanging member 150B with a coating capable of preventing adsorption of negative ions. In addition, when other design conditions are satisfied, the hanging member 150B and/or the module main bodies 141, 141A may be made of a material other than a metal material, for example, a resin, which can prevent negative ion adsorption. In this way, the loss of negative ions due to the adsorption of negative ions to the metal hoist 150 and/or the module bodies 141, 141A can be prevented.
In this way, for example, the ion generating portions 142 and 142A in the air outlet region extending from the upper side to the lower side or from one side in the width direction to the other side to the outside of the air outlet 111b generate negative ions after being energized, and the generated negative ions can be present in a large air volume region of the air outlet passage in a large amount, whereby dust and particles in the air can be removed to a greater extent by the presence of a large amount of negative ions in the large air volume region, and sterilization and disinfection can be performed more effectively.
The ion generating parts 142, 142A, the outermost ends of which are flush with the side edges or the lower edges of the module mounting part 151B of the hanging member 150B, generate negative ions after being energized, and the generated negative ions can enter the air outlet area outside the air outlet 111B by kinetic energy (downward or leftward), whereby the generated negative ions can remove dust and particles in the air as well, and sterilization and disinfection can be performed.
(technical effects)
According to the embodiment of the present invention, in the air conditioning indoor unit 100 and the air conditioner including the air conditioning indoor unit 100 of the present invention, the case 111 is provided with the circumferential flange portion 111d that encloses at least a part of the air outlet 111b and at least a part of the outer wall surface of the machine room 110b on the side of the air outlet 111b, the air conditioning indoor unit 100 further includes the ion generating modules 140 and 140A, the ion generating modules 140 and 140A are mounted or fixed to the circumferential flange portion 111d by the connection structure 150, and are located on the downstream side of the air outlet section 110A2 of the heat exchange chamber 110A of the air conditioning indoor unit 100, and therefore, dust and particles in the air outlet passage can be adsorbed by the negative ions generated by the ion generating modules 140 and 140A, and thus, the air in the air outlet passage can be sterilized and disinfected, and the air blown from the air conditioning indoor unit does not need to be replaced frequently, and the air to be cleaned by the adsorption material (consumable material) including the active carbon or the like, and the ion generating modules 140A can be mounted on the downstream side of the air conditioning indoor unit in a new type of the air conditioning indoor unit, and thus the air conditioning indoor unit can be replaced.
(modification)
Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
For example, in the embodiment of the present invention, the connection structure 150 is a member for attaching the ion generating modules 140, 140A to the indoor unit main body 110, and the "H" shaped attachment plate 150A shown in fig. 4 and 6 and the hanging member 150B shown in fig. 7 and 8 are exemplified, but the present invention is not limited thereto, and any other connection structure suitable for being attached to the outside of the casing 111 of the air conditioning indoor unit 100 may be used.
For example, in the embodiment of the present invention, as shown in fig. 4 and 6, the "H" -shaped mounting plate 150A has the burring parts 152A, 152A as the "|" part of the "H" -shape integrally formed at both ends of the module mounting part 151A as the "-" part, but the present invention is not limited to this, and may be a hanging tool having a "T" -shape, and the burring part of the "-" part of the "T" -shape integrally formed only at one end of the module mounting part as the "|" part.
In the embodiment of the present invention, the connection structure 150 is formed as a single member as shown in fig. 3 to 8, but the present invention is not limited thereto, and the connection structure 150 may be an integral structure integrally formed with the module bodies 141, 141A of the ion generating modules 140, 140A, or may be an assembly structure capable of being assembled with the ion generating units 142, 142A into one ion generating module 140, 140A, whereby the ion generating modules 140, 140A can be directly mounted at a predetermined position outside the casing 111 of the indoor unit main body 110.
For example, in the air conditioning indoor unit 100 according to the embodiment of the present invention, the ion generating portion 142 of the ion generating module 140 protruding from the module main body 141 has a grid-shaped ion outlet 143 as shown in fig. 2, and the ion generator 141a is arranged at a position corresponding to the ion outlet 143 of the ion generating portion 142, and negative ions generated from the ion generator 141a are emitted from the ion generating portion 142 to the outside of the ion generating module 140 through the grid-shaped ion outlet 143, but the shape of the ion outlet 143 of the present invention is not limited to the grid-shaped one, and may be any other suitable shape such as a stripe shape, a single or a plurality of holes. The ion generating portion 142A of the ion generating module 140A used in the air conditioning indoor unit 100 according to the embodiment of the present invention discharges the negative ions generated by the ion generator 141Aa provided inside and near the ion outlet 143A to the outside of the ion generating module 140A through the ion outlet 143A by the hole-shaped ion outlet 143A formed in one side end surface of the module main body 141A, but the present invention is not limited to discharging the negative ions to the outside of the ion generating module 140A through the hole-shaped ion outlet 143A, and may discharge the negative ions to the outside of the ion generating module 140A through the ion outlet 143A of another shape such as a grid shape or a stripe shape.
In the plurality of mounting modes of the embodiment of the present invention, the terminals (the plurality of flat emitter electrode portions (electrodes)) of the ion generators 141a, 141Aa in the ion generating portions 142, 142A are arranged so that negative ions are generated in the width direction, that is, the direction in which the negative ions are generated is perpendicular to the air blowing direction, but the direction in which the negative ions are generated in the present invention is not limited to the width direction, and the direction in which the negative ions are generated may be made the same as the air blowing direction by adjusting the arrangement direction of the terminals (the plurality of flat emitter electrode portions (electrodes)) of the ion generators 141a, 141 Aa. At this time, the air flow is subjected to small wind resistance, and negative ions can stay in the air for a longer time.
In the installation positions of the ion generating module according to the present invention shown in fig. 6 and 8, only the ion generating sections 142 and 142A are shown to protrude into the air outlet region outside the air outlet 111b, but the present invention is not limited to this, and a small number of module bodies 141 and 141A of the ion generating modules 140 and 140A may be made to protrude into the air outlet region outside the air outlet 111b (downstream side of the air outlet section 110A2 of the indoor unit body 110), or a part of the ion generating modules 140 and 140A may be made to enter the casing 111 of the indoor unit body 110 and downstream side of the air outlet section 110A2 of the heat exchange chamber 110A.
In the embodiment of the present invention, the air conditioning indoor unit 100 is described as an example of the side air outlet type air conditioning indoor unit, but the present invention is not limited thereto, and the air conditioning indoor unit 100 may be a lower air outlet type air conditioning indoor unit, and in this case, the same technical effects as those of the above-described embodiment of the present invention can be similarly achieved only by providing the ion generating modules 140 and 140A capable of generating negative ions at appropriate positions between the indoor unit main body 110 and the air outlet panel 120 of the air conditioning indoor unit 100 (for example, on the surface of the air outlet panel 120 on the side of the space above the ceiling) or on the surface of the air outlet panel 120 on the side of the room by the "H" shaped mounting plate 150A, the hanging member 150B, or any other connection structure 150 having any suitable shape, or by integrally forming or assembling the ion generating modules 140 and 140A having connection structures.
