[0001] Case division information

[0002] This application is a divisional case based on the Chinese patent application “Application No. 201710724041.9, filed on August 21, 2017, entitled “Wall-mounted indoor unit and air conditioner”, and all the contents thereof are incorporated herein by reference. Technical Field

[0003] The present invention relates to the technical field of air conditioners, and in particular to a wall-mounted indoor unit and an air conditioner. Background Art

[0004] Conventional wall-mounted indoor units have an air outlet located on the front panel of the housing. When the unit is delivering air, the impeller pulls the heat-exchanged air out through the outlet. When a user is within the air conditioning unit's air supply range, the airflow from the outlet is high and blows directly toward the user. Especially in the hot summer, prolonged exposure to cold air can cause discomfort and negatively impact health, especially for the elderly and children, who are more susceptible to colds and other illnesses. Summary of the Invention

[0005] The main purpose of the present invention is to propose a wall-mounted indoor unit, which aims to achieve two-way split air outlet, and at least one of the ways is windless air outlet, thereby reducing the wind speed and achieving windless air outlet, so as to improve the comfort of users using the air-conditioning indoor unit.

[0006] To achieve the above-mentioned objectives, the present invention proposes a wall-mounted indoor unit and an air conditioner including the wall-mounted indoor unit, wherein the wall-mounted indoor unit includes a shell, a first wind shield and a second wind shield; wherein the shell has an air outlet duct located on its inner side, and a first air outlet connected to the air outlet duct, and the shell is provided with a second air outlet connected to the air outlet duct on the upper side or lower side of the first air outlet; the first wind shield is rotatably installed on the first air outlet to rotate to open or cover the first air outlet; the second wind shield is installed on the second air outlet, and the first wind shield and / or the second wind shield are provided with wind dispersion holes.

[0007] Preferably, the second air outlet is provided on the upper side of the first air outlet, and the side of the second wind shield away from the first air outlet is rotatably connected to the shell.

[0008] Preferably, the second air outlet is provided at a lower side of the first air outlet, and a side portion of the second baffle adjacent to the first air outlet is rotatably connected to the shell.

[0009] Preferably, the wall-mounted indoor unit has a volute for forming the air outlet duct, the volute is provided with an air passage connecting the air outlet duct and the second air outlet, and a spoiler is rotatably installed in the air passage.

[0010] Preferably, there are multiple spoilers, which are sequentially spliced ​​along the length direction of the air passage, and each of the short spoilers is pivotally connected to the volute.

[0011] Preferably, the spoiler is provided with a plurality of spoiler holes on its plate surface.

[0012] Preferably, the second wind shield is provided with air dispersion holes, and the air dispersion holes on the second shield and the air dispersion holes on the spoiler are staggered with each other in the air outlet direction of the air passage.

[0013] Preferably, the inner wall surface of the air passage is provided with a heat-insulating layer.

[0014] Preferably, the inner surface of the first windshield is provided with a heat-insulating layer.

[0015] Preferably, a guide plate located in the air passage is rotatably installed in the volute.

[0046]

[0047] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0049] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0050] In addition, if there are descriptions involving "outdoor side", "indoor side", etc. in the embodiments of the present invention, the descriptions of "outdoor side", "indoor side", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "outdoor side" and "indoor side" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] The present invention provides a wall-mounted indoor unit and an air conditioner comprising the wall-mounted indoor unit. The wall-mounted indoor unit can achieve windless air discharge, thereby improving the comfort of users using the wall-mounted indoor unit.

[0052] See also Figure 1 and Figure 2 In a first embodiment of the wall-mounted indoor unit of the present invention, the wall-mounted indoor unit includes a shell 100, a first wind shield 10 and a second wind shield 20; wherein the shell 100 has an air outlet duct 1a located on the inner side thereof, and a first air outlet connected to the air outlet duct 1a, and the shell 100 is provided with a second air outlet connected to the air outlet duct 1a on the upper side or lower side of the first air outlet; the first wind shield 10 is rotatably installed on the first air outlet to rotate to open or cover the first air outlet; the second wind shield 20 is installed on the second air outlet, and the first wind shield 10 or the second wind shield 20 is penetrated by a wind dispersion hole.

[0053] The housing 100 includes a rear shell and a front shell 110 located in front of the rear shell. The rear shell and the front shell 110 enclose a cavity for mounting the heat exchanger 1 and the air duct assembly of the wall-mounted indoor unit. The top of the front shell 110 has an air inlet 111. The first air outlet is located at the lower end of the front panel of the front shell 110, and the second air outlet is located above the first air outlet (equivalent to a position near the lower end of the front panel), or the second air outlet is located above the first air outlet (equivalent to the bottom of the front shell 110). The heat exchanger 1 is adjacent to the air inlet 111. The air duct assembly includes a rotor 2, which is located on the side of the heat exchanger 1 facing away from the air inlet 111 and is located at the inner end of the outlet duct 1a. When the wall-mounted indoor unit is in operation, the rotor 2 drives airflow into the air inlet 111. After heat exchange in the heat exchanger 1, the airflow is delivered to the air outlet through the outlet duct 1a, and finally blows out from the air outlet into the room.

[0054] The first windshield 10 is rotatably connected to the housing 100, so that the first windshield 10 can be rotated to open or close the first air outlet. The wall-mounted indoor unit also includes a drive device disposed within the housing 100, connected to the first windshield 10 to drive the first windshield 10 to rotate. For example, the first drive device includes a first motor and a first crank, one end of the first crank being connected to the first motor, and the other end of the crank being connected to the first windshield 10, so that the first motor drives the first crank to rotate, thereby driving the first windshield 10 to rotate. Alternatively, the first drive device includes a first motor, a gear connected to the first motor, and a connecting rod, one end of the connecting rod being slidably connected to the housing 100, the other end of the connecting rod being connected to the first windshield 10, and the connecting rod being provided with a rack that meshes with the gear, so that the first motor drives the gear to rotate, thereby driving the connecting rod to rotate, thereby driving the first windshield 10 to rotate.

[0055] There is no limitation on the method of installing the second wind shield 20 at the second air outlet. The specific method should be selected based on whether the second wind shield 20 is provided with air dispersion holes. If the second wind shield 20 is a perforated plate without air dispersion holes, the second wind shield 20 can be snap-connected or pivotally connected to the shell 100. If the second wind shield 20 is a solid plate without air dispersion holes, the second wind shield 20 should be rotatably connected to the shell 100.

[0056] The technical solution of the present invention is to provide a second air outlet on the housing 100 and a second wind shield 20 installed at the second air outlet, and the first wind shield 10 or the second wind shield 20 is provided with a wind dispersion hole. When the wall-mounted indoor unit is in operation, the airflow blown out from the air outlet duct 1a is diffused out through the wind dispersion holes on the first wind shield 10 or the second wind shield 20. During this process, the wind speed of the airflow is reduced, and the airflow is dispersed and softened, so that the wind speed of the airflow blowing into the room is small and relatively soft, and the user cannot feel the flow of the airflow, thereby achieving a windless air outlet effect. Compared with conventional wall-mounted indoor units that blow air directly into the room, the wall-mounted indoor unit of the present invention can achieve two-way diversion of air, and at least one of the ways is windless air outlet, thereby reducing the wind speed and achieving windless air outlet, so as to improve the user's comfort when using the air conditioner indoor unit.

[0057] See also Figure 2 In this embodiment, the second air outlet is arranged on the upper side of the first air outlet, the first baffle is provided with air dispersion holes, the second air shield 20 is not provided with air dispersion holes, and the second air shield 20 is rotatably connected to the shell 100.

[0058] Specifically, the first air outlet and the second air outlet are both arranged on the front panel of the surface shell 110, and the second air outlet is located above the first air outlet; the volute 120 has an upper volute 120, and the air passage 2a is arranged on the upper volute 120.

[0059] like Figure 3-A As shown, in this mode, the first wind deflector 10 is opened and the second wind deflector 20 is closed. The airflow of the wall-mounted indoor unit is not divided, and only one airflow is formed and blown out directly from the first air outlet to achieve rapid cooling. This mode is suitable for the initial stage of cooling of the wall-mounted indoor unit to quickly cool the room.

[0060] like Figure 3-B As shown, in this mode, the first wind deflector 10 is closed and the second wind deflector 20 is opened, and the airflow of the wall-mounted indoor unit is divided into two airflows. The first airflow diffuses out through the air diffusion holes on the first wind deflector 10, so that there is no wind out of the first air outlet; the second airflow is directly blown upward through the second air outlet, and then naturally settles down in a spray shape. During this process, the wind speed decreases, so that there is no wind out of the second air outlet.

[0061] Since the second air outlet is located above the first air outlet, there are two ways to rotatably connect the second wind shield 20 to the housing 100:

[0062] Same method Figure 3-BAs shown, the side of the second windshield 20 near the first air outlet is rotatably connected to the housing 100. When the second windshield 20 is opened, it extends the air supply distance of the second air outlet. The airflow from the second air outlet is blown to a higher position and then naturally settles, making it less likely to blow onto the user.

[0063] Method 2 Figure 3-C As shown, the side of the second windshield 20 away from the first air outlet is rotatably connected to the housing 100. In this way, the airflow blown out from the second air outlet is blocked by the inner surface of the second windshield 20 and will not blow toward the outer surface of the housing 110, thereby preventing condensation from forming on the outer surface of the housing 110.

[0064] The second windshield 20 and the housing 100 may be connected by hinges or pivots. For example, rotating shafts are provided at both ends of the second windshield 20 , and shaft holes for inserting the rotating shafts are provided on the housing 100 .

[0065] See also Figure 2 In order to adjust the air flow through the second air outlet, the wall-mounted indoor unit has a volute 120 for forming an air outlet duct 1a. The volute 120 is provided with an air passage 2a connecting the air outlet duct 1a and the second air outlet, and a spoiler 30 is rotatably installed in the air passage 2a.

[0066] Specifically, the volute 120 is located within the housing 100 and is used to form the air outlet duct 1a. The side of the spoiler 30 that is closer to the first air outlet is pivotally connected to the volute 120. By controlling the angle of rotation of the spoiler 30, the opening of the air passage 2a is adjusted, thereby controlling the airflow through the second air outlet. For example, when the spoiler 30 is rotated so that its plate surface is aligned with the air outlet direction of the air passage 2a, the air flow through the second air outlet is greater; when the spoiler 30 is rotated so that its plate surface forms an angle with the air outlet direction of the air passage 2a, the air flow through the second air outlet is less; and when the spoiler 30 is rotated so that its plate surface is perpendicular to the air outlet direction of the air passage 2a, the air flow through the second air outlet is less.

[0067] As for the method of controlling the rotation of the spoiler 30, it can be manually controlled or driven by a motor.

[0068] See also Figure 2 To enhance the wind-free effect of the second air outlet, the spoiler 30 is equipped with multiple spoiler holes on its surface. These holes initially disturb the airflow, reducing its velocity. This arrangement allows the airflow to flow more smoothly as it exits the second air outlet, gradually being disturbed by the spoiler holes on the spoiler 30 and diffused by the air holes on the second wind deflector 20.

[0069] See also Figure 2 Considering that if the spoiler holes on the spoiler 30 and the air dispersion holes on the second baffle plate are arranged opposite to each other in the air outlet direction of the air passage 2a, the airflow passing through the spoiler 30 will directly pass through the air dispersion holes on the second wind shield 20 along the air outlet direction, resulting in the spoiler 30 not significantly disturbing the airflow and failing to effectively reduce the airflow speed.

[0070] Therefore, in this embodiment, the air dispersion holes on the second baffle plate and the air dispersion holes on the spoiler 30 are staggered in the direction of air flow out of the air passage 2a. This allows the airflow to be buffered within the air passage 2a after passing through the spoiler 30 before being dispersed through the air dispersion holes on the second air baffle plate 20. This further reduces the airflow velocity and enhances the wind-free effect of the second air outlet.

[0071] See also Figure 2 A deflector 40 is rotatably mounted within the volute 120 and positioned within the air passage 2a. By adjusting the rotation angle of the deflector 30, the direction of the airflow within the air outlet passage can be adjusted to deflect toward the first or second air outlet, thereby controlling the amount of airflow passing through the first and second air outlets.

[0072] See also Figure 4 and Figure 5 In the second embodiment of the wall-mounted indoor unit of the present invention, the difference from the first embodiment is that the first baffle is not provided with air dispersion holes, while the second air baffle 20 is provided with air dispersion holes.

[0073] See also Figure 5 To enhance the wind-free airflow effect of the first air outlet, the guide plate 40 may be provided with air dispersion holes on its surface. When the guide plate is rotated so that its surface forms an angle (a right angle or an acute angle) with the airflow direction of the air outlet channel, the airflow velocity decreases after passing through the air dispersion holes on the guide plate, resulting in a lower and softer airflow to the first air outlet. The user cannot feel the airflow, thus achieving the wind-free airflow effect of the first air outlet.

[0074] like Figure 6-A As shown, in this mode, the first wind deflector 10 is opened, the second wind deflector 20 and the spoiler 30 are both closed, and the airflow of the wall-mounted indoor unit is blown out directly from the first air outlet to achieve rapid cooling. This mode is suitable for the initial stage of cooling of the wall-mounted indoor unit to quickly cool the room.

[0075] like Figure 6-BAs shown, in this mode, the first wind deflector 10 and the spoiler 30 are both opened, the second wind deflector 20 is closed, and the guide plate 40 is rotated until its plate surface is perpendicular to the air outlet direction of the air outlet duct 1a. The airflow of the wall-mounted indoor unit is divided into two airflows. The first airflow (as shown in "I" in the figure) passes through the wind holes on the guide plate 40 and is blown out through the first air outlet; the second airflow (as shown in "II" in the figure) passes through the air passage 2a and the wind holes on the second wind deflector 20 and diffuses upward. In this way, both the first air outlet and the second air outlet can achieve windless air outlet, and the air outlet range is wider.

[0076] Considering that condensation water is likely to form on the outer surface of the first wind shield 10 when the air flow is blown out from the first air outlet, it is preferred that an insulation layer 4 is provided on the inner surface of the first wind shield 10 to avoid condensation water forming on the outer wall surface of the first wind shield 10 when the air flow passes through the first air outlet.

[0077] See also Figures 7 to 9 In the third embodiment of the wall-mounted indoor unit of the present invention, the difference from the above-mentioned second embodiment is that the second air outlet is arranged on the lower side of the first air outlet, and the second wind shield 20 corresponding to the second air outlet is also located on the lower side of the first air outlet.

[0078] Specifically, the first air outlet is provided on the front panel of the face shell 110 , and the second air outlet is provided at the bottom of the face shell 110 ; the volute 120 has a lower volute 120 located below the upper volute 120 , and the air passage 2a is provided in the lower volute 120 .

[0079] like Figure 10-A As shown, in this mode, the first wind deflector 10 is opened, the second wind deflector 20 and the spoiler 30 are both closed, and the airflow of the wall-mounted indoor unit is blown out directly from the first air outlet to achieve rapid cooling. This mode is suitable for the initial stage of cooling of the wall-mounted indoor unit to quickly cool the room.

[0080] like Figure 10-B As shown, in this mode, the first wind deflector 10 is opened, the second wind deflector 20 and the spoiler 30 are closed, and the guide plate 40 is rotated until its plate surface is perpendicular to the air outlet direction of the air outlet duct 1a. The airflow of the wall-mounted indoor unit is blown into the room through the air dispersion holes on the guide plate 40 and becomes soft, thereby achieving windless air outlet from the first air outlet.

[0081] like Figure 10-C As shown, in this mode, the first wind deflector 10 is closed, the second wind deflector 20 is closed, and the spoiler 30 is opened. The airflow of the wall-mounted indoor unit only diffuses downward through the air holes on the second wind deflector 20, and will not blow directly towards the user. In this way, windless air discharge from the second air outlet can be achieved.

[0082] like Figure 10-D As shown, in this mode, the first wind deflector 10 and the spoiler 30 are both open, the second wind deflector 20 is closed, and the guide plate 40 is rotated until its plate surface is perpendicular to the air outlet direction of the air outlet duct 1a. The airflow of the wall-mounted indoor unit is divided into two airflows. The first airflow (as shown in "I" in the figure) passes through the air dispersion holes on the guide plate 40 and blows out through the first air outlet; the second airflow (as shown in "II" in the figure) diffuses downward through the air dispersion holes on the second wind deflector 20 and does not blow directly towards the user. In this way, both the first and second air outlets can be blown out without a sense of wind, and the air outlet range is wide. In addition to being applicable to the air conditioning cooling state, this mode can also be used in the air conditioning heating state, and also delivers warm air to the bottom floor of the room to achieve a warming effect.

[0083] Please refer again Figure 9 Considering that when the airflow passes through the air passage 2a, condensation water is easily generated on the rear wall of the volute 120 adjacent to the air passage 2a, it is preferred that an insulation layer 4 is provided on the inner wall of the air passage 2a. The insulation layer 4 is made of insulation material, which can be insulation cotton or insulation foam.

[0084] See also Figure 11 and Figure 12 The fourth embodiment of the wall-mounted indoor unit of the present invention is different from the first embodiment in that both the first wind shield 10 and the second wind shield 20 are provided with air dispersing holes.

[0085] like Figure 13-A As shown, in this mode, the first wind deflector 10 is opened, the second wind deflector 20 and the spoiler 30 are both closed, and the airflow of the wall-mounted indoor unit is blown out directly from the first air outlet to achieve rapid cooling. This mode is suitable for the initial stage of cooling of the wall-mounted indoor unit to quickly cool the room.

[0086] like Figure 13-B As shown, in this mode, the first wind shield 10 and the second wind shield 20 are closed, and the guide plate 40 is rotated until its plate surface is consistent with the air outlet direction of the air outlet duct 1a. The airflow of the wall-mounted indoor unit is divided into two airflows. The first airflow (as shown in "I" in the figure) is blown out through the air dispersion holes on the first wind shield 10; the second airflow (as shown in "II" in the figure) is diffused upward through the air dispersion holes on the second wind shield 20, and will not be blown directly towards the user. In this way, both the first air outlet and the second air outlet can achieve windless air outlet, and the air outlet range is wider.

[0087] See also Figure 14 and Figure 15In order to achieve an adjustable spoiler range of the spoiler 30, based on any of the above embodiments, in the fifth embodiment of the wall-mounted indoor unit of the present invention, the number of spoilers 30 is multiple, and the multiple spoilers 30 are spliced ​​in sequence along the length direction of the air passage 2a, and each of the spoiler short plates is pivotally connected to the volute 120.

[0088] Specifically, each spoiler 30 is arranged in a long strip shape, and multiple spoilers 30 are spliced ​​in sequence along the extension direction of the wind channel 2a. The side of the spoiler 30 adjacent to the first air outlet is pivotally connected to the housing 100, so as to achieve the effect of segmented spoiling of the wind channel 2a by controlling the number of spoilers 30 opened, thereby achieving the segmented windless air outlet of the first air outlet (such as Figure 14 ) or no wind at all (such as Figure 15 ).

[0089] See also Figure 16 Based on any of the above embodiments, considering that if the air diffusion hole 3 is provided in a straight cylindrical shape through the first wind shield 10 or the second wind shield 20, then when the wall-mounted indoor unit is cooling, the airflow is directly blown outward after passing through the air diffusion hole 3, and the airflow does not pass through the outer plate surface of the first wind shield 10 or the second wind shield 20, resulting in a large temperature difference between the inner side and the outer side of the first wind shield 10, and the water vapor in the air is easily condensed into condensed water on the outer plate surface of the first wind shield 10.

[0090] To avoid this, the outer ends of the air diffusion holes 3 on the first or second windshield 10, 20 are preferably arranged to expand outward in an arc shape. Taking the first windshield 10 as an example, when air flows out of the air diffusion holes 3 on the first windshield 10, the air diffuses smoothly outward at the expanded ends of the air diffusion holes 3 to the outer surface of the first windshield 10, thereby balancing the temperature difference between the inner and outer surfaces of the first windshield 10 and preventing the formation of condensation on the outer surface of the first windshield 10.

[0091] See also Figure 17 In other embodiments, in order to achieve a better windless effect, the wind diffusion holes 3 are arranged in a curved direction, so that the wind diffusion holes 3 are arranged in a curved shape to penetrate the first wind shield 10 or the second wind shield 20. Compared with the straight-cylindrical wind diffusion holes 3, in this embodiment, the curved wind diffusion holes 3 have a larger wind resistance and more effectively reduce the airflow speed at the air outlet, thereby achieving a better windless effect.

[0092] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
