Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Fig. 1 is a sectional view of an indoor unit in the related art.

Referring to fig. 1, in the related art, an indoor unit of a vertical air conditioner includes an air inlet grill 800, a heat exchanger 600, a cross-flow fan 700, a connection assembly, a left pillar 400, a right pillar 200, an air duct casing 100, and an air deflector 500; the air duct shell 100 comprises a front vortex tongue 110 and a rear vortex tongue 120, and the front vortex tongue 110 and the rear vortex tongue 120 define an opening communicated with an air outlet of the vertical air-conditioning indoor unit; the left upright column 400 and the right upright column 200 are tightly installed at the inner side of the air inlet grille 800 and are arranged at intervals, and the right upright column 200 is tightly connected with the right end of the heat exchanger 600; the heat exchanger 600 is arranged in the air inlet grille 800, and two ends of the heat exchanger 600 are respectively connected with the front volute tongue 110 and the rear volute tongue 120 through the connecting components; the connecting assembly comprises a left connecting plate and a right connecting plate, the left end of the heat exchanger 600 is connected with the front volute tongue 110 through the left connecting plate, and the right end of the heat exchanger 600 is connected with the rear volute tongue 120 through the right connecting plate; the cross-flow fan 700 is installed between the front and rear scroll tongues 110 and 120 and is located inside the heat exchanger 600; the air deflector 500 is slidably mounted on the duct housing 100 and defines a gap with the rear volute tongue 120.

Through careful analysis, the inventor of the present disclosure finds that the main reason for the above problem is that when the indoor unit does not operate, the air deflector is used for shielding the air outlet of the indoor unit to improve the aesthetic property of the indoor unit, and therefore, a gap is defined between the air deflector and the rear vortex tongue to ensure the movement of the air deflector. When the indoor unit sends cold air to the right side, the cold air flowing out of the opening can be divided into two parts, one part of cold air enters the room through the air outlet, and the other part of cold air enters the gap between the air deflector and the rear volute tongue and contacts with the inner side of the right upright post.

During refrigeration, under the action of the cross-flow fan, hot air introduced from the air inlet grille is divided into two parts, one part of hot air is changed into cold air after exchanging heat with the heat exchanger and passes through the opening, and the other part of hot air is stored between the heat exchanger and the air inlet grille and is contacted with the outer side of the right upright post.

Therefore, the two sides of the right upright post are respectively contacted with hot air and cold air, so that the cold and hot water on the surface of the right upright post are crossed to form a condensation environment for the condensed water to generate. Because the right upright post is positioned outside the water pan of the indoor unit, condensed water formed on the right upright post can flow downwards along the right upright post and enters the indoor space through the gap of the indoor unit, and therefore the water leakage phenomenon of the indoor unit occurs.

In view of the above problems, the inventors of the present disclosure first thought that a plurality of layers of insulation liners are adhered to the surface of the right pillar to avoid a condensation environment caused by condensed water on the surface of the right pillar, but the number of insulation liners required in this way is large, which may increase the cost of the indoor unit.

In view of this, the inventor of this disclosure has abandoned the scheme of heat preservation liner, through be provided with the wall of keeping out the wind of outside extension on the surface of back vortex tongue, and keep out the wind wall and be located the place ahead of right stand, perhaps, keep out the wind wall and the preceding terminal surface parallel and level of right stand and have the clearance with the preceding terminal surface, make right stand shielded, thereby cold wind can not contact with right stand, perhaps, most cold wind can not contact with right stand, and then the condensation environment that the on-surface of right stand can not form and supply the condensate water to form, in order to avoid the formation of comdenstion water, and, cancel the heat preservation liner, can also reduce the cost of indoor set.

The preferred technical solution of the indoor unit and the air conditioner of the present invention will be described with reference to the following embodiments.

Fig. 2 is a sectional view of the indoor unit of the present embodiment; FIG. 3 is an isometric view of the air chute housing of the present embodiment.

As shown in fig. 2 and 3, the present embodiment provides an indoor unit including a duct casing 100 and a right pillar 200.

The air duct housing 100 includes a front volute tongue 110 and a rear volute tongue 120. Wherein, the inner surface of the rear volute tongue 120 and the front volute tongue 110 define an opening communicating with the outlet of the indoor unit.

The outer surface of the rear volute tongue 120 is provided with a wind shielding wall 300 extending outward. The wind shielding wall 300 is located in front of the right pillar 200, or the wind shielding wall 300 is flush with the front end surface of the right pillar 200 and has a gap with the front end surface.

The wall 300 of keeping out the wind is located the place ahead of right stand 200, perhaps keeps out the wind wall 300 and the preceding terminal surface parallel and level of right stand 200 and has the clearance with preceding terminal surface for keep out the wind wall 300 and can block cold wind, avoid cold wind and the contact of right stand 200, perhaps, make most cold wind not contact with right stand 200. The above-mentioned cold air refers to a part of cold air flowing from the opening to between the air deflector 500 and the rear volute tongue 120.

When the indoor unit is used for refrigerating, cold air entering between the air deflector 500 and the rear volute tongue 120 is in contact with the air baffle wall 300, then the air baffle wall 300 enables the cold air to enter the air deflector 500 and a shell of the indoor unit through a gap between the air deflector 500 and the right upright post 200, and finally the cold air enters the indoor through the gap of the indoor unit and/or an air outlet of the indoor unit so as to reduce the indoor air temperature. Therefore, the provision of the wind shielding wall 300 makes the cool wind not contact with the right pillar 200, or reduces the amount of contact of the cool wind with the right pillar 200, thereby avoiding the occurrence of a condensation environment for the formation of condensed water on the surface of the right pillar 200.

The wind shielding wall 300 is located in front of the right upright post 200, which means that when the indoor unit is used, one surface of the indoor unit facing a user is a front surface, and one surface of the indoor unit opposite to the front surface is a rear surface, which can also be called a back surface, wherein an air outlet of the indoor unit is located on the front surface, and an air inlet of the indoor unit is located on the rear surface, so that the wind shielding wall 300 is located in front of the right upright post 200 with respect to the user.

The wind shielding wall 300 is flush with the front end surface of the right pillar 200 and has a gap with the front end surface, wherein the user is used as a reference object, and the surface of the right pillar 200 facing the air outlet of the indoor unit or the user is the front end surface. The wind shielding wall 300 has a gap with the front end surface, and a gap is formed between the left side of the front end surface and the end surface of the wind shielding wall 300 in the left-right direction with respect to a user, and the gap ensures installation of the right column 200, and can be used to form a hot air passage for hot air to flow, so that a junction area of cold air and hot air is outside the right column 200.

The wind shielding wall 300 is located in front of the right pillar 200, or the wind shielding wall 300 is flush with and has a gap with the front end surface of the right pillar 200, which can be understood as that there is a gap between the wind shielding wall 300 and the side end surface of the right pillar 200, the gap is used for ensuring the installation of the right pillar 200, and the gap forms a hot air passage for flowing hot air, so that the intersection area of the hot air and the cold air is not on the surface of the right pillar 200, thereby avoiding the formation of condensed water.

It should be noted that, when the two ends of the right upright post 200 are respectively connected to the right end of the heat exchanger 600 and the air inlet grille 800, the hot air entering from the air inlet grille 800 is blocked by the right upright post 200, so that the gap between the right upright post 200 and the wind shielding wall 300 does not function as a hot air passage. When the right pillar 200 is installed on the air inlet grill 800 with a gap from the right end of the heat exchanger 600, the hot wind entering from the air inlet grill 800 may intersect with the cold wind.

Referring to fig. 2, the duct housing 100 functions to define an air outlet duct with the heat exchanger 600, the left and right connection plates, and the like, and the cross flow fan 700 is installed in the air duct and is fixedly coupled with the duct housing 100.

As shown in fig. 3, the duct casing 100 further includes an upper cover 130 and a lower cover 140, the upper cover 130 and the lower cover 140 are respectively disposed at the top and the bottom of the indoor unit, the upper cover 130 and the lower cover 140 are used for connecting the front volute tongue 110 and the rear volute tongue 120, and the upper cover 130 is further used for carrying a motor for driving the cross-flow fan to rotate and the vertical swinging blade to rotate. Wherein, both ends of the cross flow fan 700 are rotatably connected with the upper end cap 130 and the lower end cap 140, respectively.

The indoor unit further includes an air guide plate 500 slidably mounted on the upper cover 130 and an air inlet grill 800. The air guide plate 500 is used for shielding an air outlet of the indoor unit when the indoor unit is not in use, so that the attractiveness of the indoor unit is improved. The air inlet grill 800 is used for allowing hot air or cold air in a room to enter the indoor unit and then exchange heat with the heat exchanger 600, so that the indoor unit can be cooled or heated.

It is understood that, in order to secure the installation space of the right pillar 200 and the wind shielding wall 300 to block the cold wind from contacting the right pillar 200, a free end surface of the wind shielding wall 300 may be disposed closely to the right pillar 200, wherein the end surface refers to an end surface of the wind shielding wall 300 opposite to the rear vortex tongue 120 in the left-right direction.

In an alternative implementation, the distance between the wind shielding wall 300 and the right pillar 200 is 3mm to 5mm in the left-right direction, so that the wind shielding wall 300 is disposed closely to the right pillar 200 to ensure that a condensation environment for condensed water does not occur on the surface of the right pillar 200.

In an alternative implementation, the rear volute tongue 120 is a split structure or a unitary structure.

In order to prevent cold air from contacting the right upright post 200, the structure of the rear volute tongue 120 itself may be modified, for example, the size of the gap between the rear volute tongue 120 and the air deflector 500 is reduced, so as to reduce the amount of cold air entering between the rear volute tongue 120 and the air deflector 500. Specifically, a wind shielding structure may be provided on the rear scroll tongue 120, the wind shielding structure blocking the entrance of cold wind and being disposed closely to the wind guide plate 500.

When the rear volute tongue 120 is of an integrated structure, the wind shielding structure is integrated on the rear volute tongue 120, so that the manufacturing efficiency of the rear volute tongue 120 can be improved.

When the rear volute tongue 120 has a split structure, the rear volute tongue 120 may include a wind blocking portion and a main body portion connected to the wind blocking wall 300. The wind blocking part and the main body part are detachably connected, so that the rear volute tongue 120 can be matched with indoor units of different models to expand the use range of the rear volute tongue 120.

Therefore, the rear volute tongue 120 of the split structure or the integrated structure may be provided with a wind shielding structure to reduce the amount of cold wind entering between the wind deflector 500 and the rear volute tongue 120.

FIG. 4 is a cross-sectional view of the rear volute tongue of the one-piece construction of the present embodiment.

As shown in fig. 4, the rear vortex tongue 120 of the one-piece structure optionally includes a plate-shaped first curved section 121, a second curved section 122, and a first connection section 123.

Wherein the inner surface of the first curved section 121 defines an opening with the front volute tongue 110; the wind shielding wall 300 is provided on the outer surface of the first curved section 121.

The second bending section 122 is disposed at the opening, and a connection end of the second bending section 122 is fastened to the first bending section 121, and a free end surface of the second bending section 122 is used to define a first air duct with the air deflector 500.

The first connection section 123 is disposed on an outer surface of the first bent section 121 and serves to be securely connected with a right end of the heat exchanger 600. Through the arrangement, the structure of the rear volute tongue 120 can be simplified, and the manufacturing efficiency of the rear volute tongue 120 is improved.

The first duct is used for allowing part of the cold air or hot air flowing out of the opening to flow in, so that the cold air or hot air contacts the wind shielding wall 300.

The second curved section 122 serves as the wind shielding structure described above.

The second bending section 122 is arranged to block part of the cold air from entering the gap between the air deflector 500 and the rear vortex tongue 120, so as to reduce the amount of cold air contacting the wind shielding wall 300.

The rear volute tongue 120 defined by the first curved section 121, the second curved section 122 and the first connecting section 123 is simple in structure and can be manufactured by injection molding, so that the manufacturing cost is reduced and the production efficiency is improved.

Fig. 5 is a sectional view of the rear vortex tongue of the split type structure of the present embodiment.

As shown in fig. 5, optionally, the rear volute tongue 120 of the split-type structure includes a first plate-shaped portion 124 and a second plate-shaped portion 125.

Wherein, the inner side of the first plate-shaped part 124 and the front vortex tongue 110 define an opening and are used for being tightly connected with the right end of the heat exchanger 600 of the indoor unit; the wind shielding wall 300 is provided on an outer surface of the first plate-like portion 124.

The second plate-shaped portion 125 is disposed at the opening, the connecting end of the second plate-shaped portion 125 is tightly connected with the first plate-shaped portion 124, and the outer surface of the second plate-shaped portion 125 is used for defining a second air duct with the air deflector 500. Through the arrangement, the application range of the rear volute tongue 120 is expanded, and the manufacturing cost of the rear volute tongue 120 is reduced.

The second duct is used for allowing part of the cold air or hot air flowing out of the opening to flow in, so that the cold air or hot air contacts the wind shielding wall 300.

The second plate-like portion 125 serves as the wind shielding structure described above.

Because the first plate-shaped part 124 and the second plate-shaped part 125 define the rear volute tongue 120 with a split structure, when the rear volute tongue 120 is matched with the air deflector 500 with different structures, only the structure of the second plate-shaped part 125 needs to be changed, and the structure of the first plate-shaped part 124 does not need to be changed, so that the mold for manufacturing the first plate-shaped part 124 can be continuously used, and the mold opening cost of the rear volute tongue 120 is further reduced.

Referring to fig. 5, exemplarily, a cross section of the first plate-like portion 124 includes a third bent section and a second connection section. Wherein the inner surface of the third curved section defines an opening with the front volute tongue 110. The second connection section is disposed on an outer surface of the third bending section and is fixedly connected with a right end of the heat exchanger 600.

Referring to fig. 5, the cross-section of the second plate-like portion 125 illustratively includes a first polygonal segment and a second polygonal segment. Wherein, the connecting end of the first polygonal section is connected with the connecting end of the second polygonal section, and the free end of the first polygonal section is tightly connected with the first plate-shaped part 124. The first and second polygonal segments define an L-shaped configuration, and the angle between the second polygonal segment and the first plate portion 124 is acute.

The second polygonal section and the air deflector 500 define a second air duct, and the second polygonal section may be rectangular.

In an alternative implementation, the right upright 200 is a tubular structure or a plate-like structure.

Fig. 6 is a sectional view of the right pillar of the plate-like structure of the present embodiment.

As shown in fig. 6, the right pillar 200 of the plate-like structure optionally includes a first plate section 210, a bent section 220, and a second plate section 230.

Wherein, the opposite ends of the bending section 220 are respectively fastened and connected with the connecting ends of the first plate section 210 and the second plate section 230;

the first flat plate section 210 is used for being tightly connected with the right end of the heat exchanger 600; the second plate section 230 is adapted to be securely connected to the air intake grill 800. Through the arrangement, direct intersection of cold air and hot air can be avoided.

Because the first flat plate section 210 is fastened and connected with the heat exchanger 600, the bending section 220 is located between the air inlet grille 800 and the heat exchanger 600, so that when the indoor unit is refrigerating, the bending section 220 can block hot air, the hot air is prevented from directly intersecting with cold air, and the efficiency in a hot air inlet duct is improved under the action of the cross flow fan 700.

It should be noted that the right pillar 200 of the plate-shaped structure can be combined with the two rear vortex tongue 120 structures arbitrarily, for example, the rear vortex tongue 120 of the split structure.

As shown in fig. 7, optionally, the right upright 200 of the tubular structure comprises a plate-shaped first horizontal section 240, a second horizontal section 250, a first vertical section 260 and a second vertical section 270;

wherein, both ends of the first vertical section 260 are respectively fastened with the first end sections of the first horizontal section 240 and the second horizontal section 250, and the first horizontal section 240 and the second horizontal section 250 are located at the same side of the first vertical section 260.

The connecting end of the second vertical section 270 is fastened to the second end of the second horizontal section 250, the second vertical section 270 and the first vertical section 260 are respectively located at two sides of the second horizontal section 250, and the second vertical section 270 is used for being fastened to the air inlet grille 800. Through the arrangement, the right upright column 200 can be tightly connected with the air inlet grille 800, the upper end cover 130, the lower end cover 140 and other parts, so that the structural firmness of the indoor unit is improved.

Referring to fig. 7, the right column 200 is defined by a first horizontal section 240, a second horizontal section 250, a first vertical section 260, and a second vertical section 270, and has an open ring-shaped cross section.

It should be noted that the first vertical section 260 may include at least two sections connected in sequence to the vertical section, and the axes of the two sections are parallel and arranged at intervals, so that a reinforcing rib structure is defined on the first vertical section 260 to avoid bending of the first vertical section 260.

The second vertical section 270 may be fastened to the air intake grill 800 by a threaded connection.

The right pillar 200 may be fabricated by bending a metal plate, or the right pillar 200 may be formed by injection molding.

Since the right pillar 200 of the tubular structure requires a small installation space, it is helpful to reduce the overall size of the indoor unit.

In an alternative implementation, the right upright post 200 is provided with an insulating layer, so that the occurrence of condensed water on the surface of the right upright post 200 can be further avoided.

The insulating layer can be mounted on the surface of the right upright post 200 by adopting bonding, clamping connection, threaded connection or other modes. Wherein, the insulating layer may be disposed on the inner side of the right pillar 200; alternatively, the insulating layer may be provided on the outer side of the right pillar 200; or, the inner side and the outer side of the right upright post 200 are both provided with heat preservation layers.

Due to the arrangement of the wind shielding wall 300, only a small part of cold wind can contact with the right upright post 200, so that a heat insulation layer can be arranged on the right upright post 200 to reduce the usage amount of the heat insulation layer, and the cost of the indoor unit is reduced.

The heat insulation layer is made of heat insulation materials, so that the temperature of the right upright post 200 can not reach the temperature formed by condensed water, and the heat insulation layer is made of polyurethane plates or polyethylene plates.

The thickness of the heat-insulating layer is 3 mm-8 mm. For example, a 5mm polyurethane sheet may be adhered to the inside of the right stud 200.

Referring to fig. 2, in an alternative implementation, the air deflection plate 500 includes a plate-shaped body portion 510 and a first bent portion 520 and a second bent portion 530. The first bending part 520 and the second bending part 530 are respectively disposed at two opposite sides of the body part 510 and located at the same side of the body part 510, and the first bending part 520 is disposed close to the opening.

The air deflector 500 can be arbitrarily matched with the two rear volute tongues 120, for example, when being matched with the rear volute tongue 120 with an integrated structure, the free end of the second bending section 220 is located at the inner side of the first bending section 520, so that the first bending section 520 and the second bending section 220 are matched with each other to block cold air from entering.

The embodiment also provides an air conditioner, which comprises an outdoor unit and the indoor unit.

Wherein, the outdoor unit is connected with the indoor unit through a pipeline.
