Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor unit of an air conditioner with dual air outlets. Background Technology

[0002] As people's demands for the appearance of cabinet air conditioners increase, single-column dual-outlet air conditioners with a more neat and aesthetically pleasing appearance are becoming increasingly popular. This type of cabinet air conditioner maximizes the integrity of the front view, meaning the air outlets can only be placed on the left and right sides of the front door panel. In columnar cabinet air conditioners, air is primarily delivered through a cross-flow fan that works in conjunction with the volute and casing. Due to the different structures of the volute and casing, the airflow rate and flow resistance differ on the left and right sides of the air outlet on the columnar cabinet air conditioner's casing. Therefore, achieving balanced airflow from the left and right outlets has become a pressing technical problem to be solved. Utility Model Content

[0031] In this invention, an indoor unit of an air conditioner with dual air outlets features a rotating cross-flow fan that creates airflow between the volute tongue and the volute surface. This airflow passes through a first and a second air duct section and exits from the first air outlet corresponding to the first air duct section and the second air outlet corresponding to the second air duct section. The first and second air outlets are respectively located on opposite side walls of the casing, increasing the air delivery range and enabling ultra-wide-angle whole-room air delivery. When the airflow generated by the cross-flow fan flows between the volute tongue and the volute surface, it is mainly concentrated on one side of the volute surface. By adjusting the airflow direction through a diversion device at the front end of the main air duct section, the flow rate of the air entering the first and second air duct sections can be adjusted, reducing the resistance of the airflow entering the first and second air duct sections. Ultimately, this adjusts the amount of airflow exiting the first and second air outlets, ensuring that the total amount of airflow exiting the first and second air outlets is equal or similar. This results in balanced left and right airflow from the indoor unit, guaranteeing effective lateral air delivery and uniform indoor temperature.

[0045] Figure 1 This is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 7 This utility model provides an indoor unit of an air conditioner with dual air outlets, including a housing 100, a flow distribution device, and a cross-flow fan 140. The housing 100 has a first air outlet 101 and a second air outlet 102. The first air outlet 101 is located on one side wall of the housing 100, and the second air outlet 102 is located on the other side wall of the housing 100. Both the first air outlet 101 and the second air outlet 102 extend vertically. An air duct is provided inside the housing 100, including a main air duct section 130, and a first air duct section 110 and a second air duct section 120 connected to the front end of the main air duct section 130. The first air duct section 110 is connected to the first air outlet 101, and the second air duct section 120 is connected to the second air outlet 102. The main air duct section 130 includes a first air duct wall 131 and a second air duct wall 132 disposed opposite to each other. The cross-flow fan 140 is disposed inside the housing 100. The first air duct wall 131 is a volute tongue surface, and the second air duct wall 132 is a volute shell surface. The volute tongue surface has a volute tongue portion that mates with the cross-flow impeller 140. The volute tongue portion, the volute shell surface, and the cross-flow impeller 140 work together. A flow diversion device is located at the front end of the main air duct section 130. The flow diversion device is configured to guide and divert the airflow from the main air duct section 130, so that part of the airflow flows to the first air duct section 110, and the remaining part flows to the second air duct section 120.

[0046] The cross-flow fan 140 rotates, creating airflow between the volute tongue and the volute surface. This airflow passes through the first air duct section 110 and the second air duct section 120, and exits from the first air outlet 101 corresponding to the first air outlet 110 and the second air outlet 102 corresponding to the second air outlet 120. The first air outlet 101 and the second air outlet 102 are respectively located on two opposite side walls of the housing 100, increasing the air delivery range and enabling ultra-wide-angle whole-house air delivery. When the airflow generated by the cross-flow fan 140 flows between the volute tongue and the volute surface, it is mainly concentrated on one side of the volute surface. By adjusting the airflow direction through the diversion device at the front end of the main air duct section 130, the flow rate of the air entering the first air duct section 110 and the second air duct section 120 can be adjusted, and the resistance of the airflow entering the first air duct section 110 and the second air duct section 120 can be reduced. Finally, the amount of airflow flowing out of the first air outlet 101 and the second air outlet 102 is adjusted accordingly, so that the total amount of airflow flowing out of the first air outlet 101 and the second air outlet 102 is equal or not much different, so that the air outlet of the indoor unit of the air conditioner is balanced from left to right, ensuring the horizontal air supply effect, and also ensuring the uniform temperature of the indoor space.

[0047] In some embodiments of this utility model, such as Figure 1 As shown, the first air duct section 110 is connected to the first air duct wall 131, and the second air duct section 120 is connected to the second air duct wall 132. The second air duct wall 132 is configured such that the airflow direction within the main air duct section 130 is towards the side of the housing 100 with the first air outlet 101. The angle of change of the airflow direction from the main air duct section 130 under the action of the second air duct section 120 is greater than the angle of change under the action of the first air duct section 110.

[0048] The tangent at the front end of the volute surface of the second air duct wall 132 faces the first air duct section 110, causing the airflow on one side of the volute surface to flow towards the inlet of the first air duct under the guidance of the volute surface. Therefore, the second air duct wall 132 is configured such that the flow direction of the airflow in the main air duct section 130 faces the side of the housing 100 with the first air outlet 101. Here, the angle at which the flow direction of the airflow in the main air duct section 130 changes under the action of the second air duct section 120 is greater than the angle at which it changes under the action of the first air duct section 110. This means that the forward angle between the flow direction of the airflow in the main air duct section 130 and the flow direction of the airflow in the second air duct section 120 is greater than the forward angle between the flow direction of the airflow in the main air duct section 130 and the flow direction of the airflow in the first air duct section 110. This arrangement increases the resistance of the airflow entering the second air duct section 120. Therefore, without the guidance of the diversion device, the amount of airflow passing through the first air duct will be much greater than the amount of airflow passing through the second air duct.

[0049] In some embodiments of this utility model, such as Figure 1As shown, the first air duct section 110 includes a third air duct wall 111 and a fourth air duct wall 112 arranged opposite to each other, with the third air duct wall 111 connected to the front end of the first air duct wall 131. The second air duct section 120 includes a fifth air duct wall 121 and a sixth air duct wall 122 arranged opposite to each other, with the fifth air duct wall 121 connected to the front end of the second air duct wall 132. The sixth air duct wall 122 and the fourth air duct wall 112 are connected by a rearwardly arched curved surface. The curved surface is symmetrically arranged about a vertical plane.

[0050] The curved surface also has the function of diverting the flow. After the airflow passes through the first air duct wall 131 and the second air duct wall 132, it is diverted by the diverting device and the curved surface and flows out from the first air duct section 110 defined by the oppositely arranged third air duct wall 111 and fourth air duct wall 112 and the second air duct section 120 defined by the oppositely arranged fifth air duct wall 121 and sixth air duct wall 122.

[0051] In some embodiments of this utility model, such as Figure 1 As shown, the plane containing the rear edges of the first air outlet 101 and the second air outlet 102 is parallel to the plane containing the front edges of the first air outlet 101 and the second air outlet 102. The plane containing the rear edges of the first air outlet 101 and the second air outlet 102 is perpendicular to the plane of symmetry of the curved surface. This arrangement ensures that the first air outlet 101 and the second air outlet 102 are of substantially the same size, while also ensuring that the rear edges of the first air outlet 101 and the second air outlet 102 are substantially at corresponding positions on the two side walls in the front-back direction, making the first air outlet 101 and the second air outlet 102 appear symmetrical and aesthetically pleasing.

[0052] In some other embodiments of this utility model, the plane in which the rear edge of the first air outlet 101 and the rear edge of the second air outlet 102 are located is perpendicular to a vertical plane extending in the front-rear direction.

[0053] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the airflow distribution device includes a first air distribution plate 910. The first air distribution plate 910 is curved. A portion of the first air distribution plate 910 is located within the main air duct section 130, and another portion is located within the second air duct section 120. The surface of the first air distribution plate 910 facing the second air duct wall 132 is a concave surface. The first air distribution plate 910 is used to guide a portion of the airflow from the main air duct section 130 into the second air duct section 120. By setting the first air distribution plate 910, the resistance to airflow from the main air duct section 130 into the second air duct section 120 can also be reduced.

[0054] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the air distribution device also includes a second air distribution plate 920 and a third air distribution plate 930. The second air distribution plate 920 is curved. The second air distribution plate 920 is located on the side of the first air distribution plate 910 away from the second air duct wall 132, and the surface of the second air distribution plate 920 facing the first air distribution plate 910 is a concave surface. The curvature of the first air distribution plate 910 is greater than that of the second air distribution plate 920. The second air distribution plate 920 is located within the main air duct section 130, and the air outlet edge of the second air distribution plate 920 is near the connection between the sixth air duct wall 122 and the fourth air duct wall 112. The third air distribution plate 930 is located on the side of the second air distribution plate 920 away from the first air distribution plate 910. The third air distribution plate 930 is curved, and the surface of the third air distribution plate 930 facing the second air distribution plate 920 is a concave surface. The angle between the cross-section at the air outlet edge of the third air distribution plate 930 and the cross-section at the air inlet edge of the third air distribution plate 930 is greater than or equal to 160°.

[0055] The second air distribution plate 920 divides the airflow from the main air duct section 130 into two approximately equal parts. One part of the airflow, guided by the surface of the second air distribution plate 920 facing the first air distribution plate 910, enters the second air duct section 120. The other part of the airflow, guided by the surface of the second air distribution plate 920 facing the third air distribution plate 930, enters the first air duct section 110. The third air distribution plate 930 facilitates the guidance of airflow into the first air duct.

[0056] In some other embodiments of this utility model, the third air distribution plate 930 is flat.

[0057] In some embodiments of this utility model, such as Figure 2 As shown, the distance between the cross-section 911 at the air inlet edge of the first air distributor 910 and the cross-section 133 at the outlet end of the second air duct wall 132 gradually decreases along the airflow direction. This arrangement allows the airflow entering the first air distributor 910 and the second air duct wall 132 to be gathered and its velocity to increase. Furthermore, in some embodiments of this utility model, such as... Figure 2 As shown, the angle α between the cross-section 911 at the air inlet edge of the first air distribution plate 910 and the cross-section 133 at the outlet end of the second air duct wall 132 is within 10°.

[0058] In some embodiments of this utility model, such as Figure 2 As shown, the distance between the cross-section 921 at the air inlet edge of the second air distribution plate 920 and the cross-section 133 at the outlet end of the second air duct wall 132 gradually decreases, gradually increases, or remains constant along the airflow direction. Further, in some embodiments of this utility model, such as... Figure 2As shown, the angle b between the cross-section 921 at the air inlet edge of the second air distribution plate 920 and the cross-section 133 at the outlet end of the second air duct wall 132 is within 5°.

[0059] In some embodiments of this utility model, such as Figure 2 As shown, the distance between the cross-section 931 at the air inlet edge of the third air distributor 930 and the cross-section 133 at the outlet end of the second air duct wall 132 gradually increases or remains constant along the airflow direction. This arrangement facilitates the third air distributor 930 in guiding airflow into the first air duct section 110. Furthermore, in some embodiments of this utility model, such as... Figure 2 As shown, the angle c between the cross-section 931 at the air inlet edge of the third air distribution plate 930 and the cross-section 133 at the outlet end of the second air duct wall 132 is within 15°.

[0060] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a vertical plane extending laterally through the air inlet edge of the first air distributor 910 intersects the air duct to form two vertical reference lines, namely the first reference line and the second reference line. The first reference line is located on either the second air duct wall 132 or the fourth air duct wall 112. The distance between the air inlet edge of the first air distributor 910 and the first reference line is 1 / 4 to 1 / 2 of the distance between the first and second reference lines. A vertical plane extending laterally through the air inlet edge of the second air distributor 920 intersects the air duct to form two vertical reference lines, namely the third reference line and the fourth reference line. The third reference line is located on either the second air duct wall 132 or the fourth air duct wall 112. The distance between the air inlet edge of the second air distributor 920 and the third reference line is 2 / 5 to 3 / 5 of the distance between the third and fourth reference lines. A vertical plane extending laterally through the air inlet edge of the third air distribution plate 930 intersects with the air duct to form two vertical reference lines, namely the fifth reference line and the sixth reference line. The sixth reference line is located on either the first air duct wall 131 or the third air duct wall 111. The distance between the air inlet edge of the third air distribution plate 930 and the sixth reference line is 1 / 7 to 1 / 3 of the distance between the fifth and sixth reference lines.

[0061] The above settings define the positions of the air inlet edges of the first air distribution plate 910, the second air distribution plate 920, and the third air distribution plate 930 in the lateral direction of the main air duct section 130. This setting helps to ensure that the amount of airflow entering the first air duct section 110 and the second air duct section 120 is roughly balanced.

[0062] In some embodiments of this utility model, such as Figure 1As shown, the first and second air outlets are respectively located at the front of their respective side walls. This arrangement allows the first and second air outlets to be as close as possible to the indoor activity area, which is beneficial for the airflow from the first and second air outlets to reach the indoor activity area as quickly as possible.

[0063] In some embodiments of this utility model, such as Figure 1 As shown, both the first and second air outlets are rectangular strip-shaped outlets with a length of 1120mm to ensure a large air volume.

[0064] In some embodiments of this utility model, such as Figure 4 As shown, the indoor unit of the air conditioner also includes a light-emitting device 160, which extends vertically and is located in the center of the front surface of the housing 100. The light-emitting device 160, located on the front surface of the housing 100 and extending vertically, enhances the aesthetics of the indoor unit and strengthens its decorative function as a household appliance. Especially for vertical air conditioner indoor units, the vertically extending light-emitting part creates visual unity with the vertical shape of the indoor unit, enhancing the overall product appeal.

[0065] In some embodiments of this utility model, such as Figure 7 As shown, the light-emitting device 160 includes a lamp housing 162 and a light-emitting part 161. The front surface of the lamp housing 162 is recessed inward to form a groove extending along the length direction of the lamp housing 162. The light-emitting part 161 is disposed at the bottom of the groove. The light-emitting part 161 is a light-emitting strip extending along the length direction of the lamp housing 162.

[0066] The groove extends along the length of the lamp housing 162, and the light strip is installed at the bottom of the groove. The lamp housing 162 can protect and fix the light strip, making it less susceptible to damage from bumps. Moreover, the concave shape of the lamp housing makes the light strip more eye-catching when it is lit.

[0067] In some embodiments of this utility model, such as Figures 2 to 4 As shown, a mounting groove extending vertically is provided in the middle of the front surface of the housing 100, and the light-emitting device 160 is disposed in the mounting groove.

[0068] In some embodiments of this utility model, such as Figure 4 As shown, the front surface of the housing 100 includes a first region and a second region located on both sides of the groove. The edge of the first region away from the groove is located on the rear side of the first region near the edge of the groove, and the edge of the second region away from the groove is located on the rear side of the second region near the edge of the groove.

[0069] The light-emitting part 161 extending vertically is disposed in the groove. The first and second regions on both sides of the groove are inclined towards the groove from both sides, that is, inclined towards the light-emitting part 161 from both sides, so that the position of the light-emitting part 161 is concave, thereby having a more eye-catching effect when the light-emitting part 161 extending vertically emits light.

[0070] In some embodiments of this utility model, such as Figure 7 As shown, the housing 100 includes a support frame 191 and two front panels 192. A mounting groove is provided in the middle of the front surface of the support frame 191. The two front panels 192 are disposed on the front side of the support frame 191 and are respectively located on both sides of the groove.

[0071] The lamp housing is installed in the mounting groove, the light-emitting part 161 is set in the groove of the lamp housing, and the two front panels 192 form the front surface of the housing 100, correspondingly forming the first region and the second region of the housing 100.

[0072] In some embodiments of this utility model, such as Figure 1 As shown, the two front panels 192 are transparent panels, preferably glass panels. When the light-emitting part 161 emits light, the emitted light is transmitted to the glass panel, making the indoor unit of the air conditioner more aesthetically pleasing.

[0073] In some embodiments of this utility model, two front panels 192 are bonded to the front surface of the support frame 191.

[0074] In some embodiments of this utility model, such as Figure 7 As shown, the first and second regions are symmetrically arranged. The groove is symmetrically arranged about the symmetrical surfaces of the first and second regions. The included angle between the first and second regions is between 170° and 175°, that is, the included angle between the front surfaces of the two front panels 192 is between 170° and 175°. The included angle between the two sides of the groove is between 90° and 95°, making the groove M-shaped.

[0075] The 192-degree angle design of the entire front panel and the concave assembly design highlight the luminous effect of the light-emitting part. Moreover, the symmetrical arrangement of the first and second regions and the symmetrical arrangement of the grooves enhances the aesthetics of the housing 100, at which point the light-emitting part 161 is positioned in the middle of the front surface of the housing.

[0076] In some embodiments of this utility model, such as Figure 4 As shown, the length L of the light-emitting part 161 is 1157mm, which makes the indoor unit of the air conditioner look better.

[0077] In some embodiments of this utility model, the indoor unit of the air conditioner further includes two formaldehyde removal devices, respectively disposed at the lower end of the first air outlet 101 and the lower end of the second air outlet 102. Each formaldehyde removal device has an opposing air-facing surface and an air-discharging surface, and is rotatably disposed about a vertical axis, so that the formaldehyde removal device has at least two rotational positions.

[0078] The airflows from the first air outlet 101 and the second air outlet 102 each pass through their corresponding formaldehyde removal devices. The formaldehyde in these airflows is either adsorbed onto the formaldehyde removal devices or directly chemically decomposed, thereby reducing the formaldehyde content in the air. Furthermore, the formaldehyde removal devices are movably positioned, which not only improves the efficiency of formaldehyde removal but also helps eliminate condensation on the devices. For example, the two rotation positions can be a first rotation position and a second rotation position. When the formaldehyde removal device is in the first rotation position, the angle between the windward surface and the airflow direction within the duct can be a right angle. At this time, the airflow blows directly towards the windward surface, maximizing the contact area between the formaldehyde removal device and the airflow, thus improving the efficiency of formaldehyde removal. When condensation appears on the formaldehyde removal device, the device can be rotated to the second rotation position. At this time, the windward surface can be parallel to the airflow direction within the corresponding first duct section 110 or second duct section 120. The airflow at the location of the formaldehyde removal device increases, and the condensation problem is solved.

[0079] In some embodiments of this utility model, such as Figure 3 As shown, the indoor unit of the air conditioner also includes two air guide grilles 170, which are respectively set at the first air outlet 101 and the second air outlet 102, so that the air blows forward in the case of wide-angle air supply, taking into account more air supply angles.

[0080] In some embodiments of this utility model, such as Figure 1 As shown, the indoor unit of the air conditioner also includes two sets of swing blades 150, which are respectively set in the first air duct section 110 and the second air duct section 120, and can realize the function of vertical air supply at the first air outlet 101 and the second air outlet 102.

[0081] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the indoor unit of the air conditioner also includes two sliding plates 180, which are located at the first air outlet 101 and the second air outlet 102, for opening and closing the corresponding first air outlet 101 and the second air outlet 102.
