Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a ducted air conditioner and an air conditioner. Background Technology

[0002] Ductless air conditioners, also known as concealed air conditioners, are typically installed by hanging them from the ceiling for air delivery. Currently, most ductless air conditioners in the industry have a single-sided duct layout, and the casing of the ductless air conditioner is generally a regular cuboid. The casing is mainly composed of sheet metal parts. The long and flat casing has weak bending strength, and the middle part is prone to collapse.

[0003] Ductless air conditioners mainly operate with two return air methods: rear return air and bottom return air. However, both return air through a single air inlet, resulting in a small return air area. Therefore, when the air volume is insufficient, the air conditioning unit typically increases the fan speed to meet the indoor air volume requirement. But when the indoor temperature is too high or too low, rapid cooling or heating is needed. To achieve rapid temperature adjustment, a higher air volume is required. However, with a single air inlet return air, the return air area is insufficient to meet the demand. The only solution is to maximize the fan speed to meet the air volume requirement, which can easily lead to equipment damage, high energy consumption, and increased fan noise, resulting in a poor user experience. Utility Model Content

[0004] To address the problem of insufficient air volume demand in existing technologies, this utility model provides a ducted air conditioner and an air conditioning unit.

[0005] The present invention adopts the following technical solution.

[0006] The first aspect of this utility model discloses a duct air conditioner, comprising: a fan chamber and a return air cover. One side of the fan cavity is an air inlet for returning air through the air inlet, and a fan for returning air is installed inside the fan cavity; The return air cover is connected to the fan cavity through an auxiliary return air throughlet, which is used to assist the return air in the fan cavity through the auxiliary return air throughlet, so that one side of the fan cavity returns air through the air inlet and the other side returns air through the auxiliary return air throughlet, thus realizing bidirectional return air.

[0007] Preferably, the duct unit further includes: a housing, one side of which is the fan chamber and the other side is the heat exchange chamber, and the return air cover is disposed between the fan chamber and the heat exchange chamber.

[0008] Preferably, the return air cover includes a first sidewall, a second sidewall, and a third sidewall. One side of the second sidewall is connected to the sidewall of the heat exchange chamber through the first sidewall, and the other side is provided with the third sidewall, so that the return air cover forms a C-shaped structure.

[0009] Preferably, the return air cover further includes a fourth sidewall, one side of which is connected to the third sidewall and the other side of which is connected to the sidewall of the fan cavity, and the third sidewall is provided with a plurality of auxiliary return air passages.

[0010] Preferably, the return air cover further includes a reinforcing fold, and the return air cover is connected to the housing through the reinforcing fold.

[0011] The second aspect of this utility model discloses an air conditioner, including the aforementioned ducted air conditioner.

[0012] The beneficial effect of this utility model is that, compared with the prior art, This utility model features a fan cavity with air return through an air inlet on one side and auxiliary air return through an auxiliary air return vent on the other side, achieving bidirectional air return. This significantly increases the air return area and air volume, better meeting the air return needs in different scenarios and improving heat exchange efficiency. At the same time, by increasing the air return volume, the fan speed is prevented from being too high, improving the fan's durability and operational stability, reducing equipment noise, and enhancing the user experience.

[0013] The return air cover of this utility model is set between the fan cavity and the heat exchange cavity, which on the one hand increases the return air volume of the fan cavity, and on the other hand avoids the loss of airflow in the heat exchange cavity, which would reduce the heat exchange efficiency.

[0014] The return air cover of this utility model forms a C-shaped structure through the connection of the first, second and third side walls, which improves the bending strength, transportation stability and resistance to deformation of the shell, and effectively prevents the middle of the shell from collapsing.

[0015] This invention connects the auxiliary return air passage on the third side wall to the fan cavity, allowing auxiliary return air to be assisted when the fan returns air, thereby increasing the return air area, which in turn reduces the fan speed, reduces noise, and improves user comfort. At the same time, because the auxiliary return air passage is only provided on the third side wall, the airflow in the heat exchange cavity will not be lost, which increases the return air volume while ensuring heat exchange efficiency.

[0016] The return air cover of this utility model improves the bending strength and overall strength of the shell by strengthening the connection between the folded edge and the shell, and improves the connection stability between the return air cover and the shell. Attached Figure Description

[0020] like Figures 1-4 As shown, Embodiment 1 of this utility model discloses a ducted air conditioner, including: a fan chamber, a heat exchange chamber, and a return air cover 3. An air inlet 12 is provided on one side of the fan cavity for returning air through the air inlet 12, and a fan 2 for returning air is provided inside the fan cavity; The heat exchange chamber is used to exchange heat with the airflow and exhaust air through the air outlet 11; The return air cover 3 is connected to the fan cavity through the auxiliary return air ...

[0021] The present invention provides bidirectional return air by having air return through the air inlet 12 on one side of the fan cavity and auxiliary return air through the auxiliary return air throughlet 15 on the other side, which greatly increases the return air area and the return air volume, better meets the return air requirements in different scenarios, improves heat exchange efficiency, and at the same time avoids excessively high fan speed by increasing the return air volume, thereby improving the durability and operational stability of the fan, reducing equipment noise, and improving the user experience.

[0022] like Figure 1 and Figure 2 As shown, the ducted air conditioner also includes a housing 1, which includes a side plate 9, a heat exchange plate 10, and a return air plate 14. The heat exchange plate 10 and the return air plate 14 are connected on the left and right sides by the side plate 9, and on opposite sides by a return air cover 3. The housing 1 has a heat exchange chamber on the side corresponding to the heat exchange plate 10 and a fan chamber on the side corresponding to the return air plate 14. The return air cover 3 is disposed between the fan chamber and the heat exchange chamber. The fan chamber has an air inlet 12 on one side and an air outlet 11 on the other side of the heat exchange chamber.

[0023] Preferably, but not limitingly, the heat exchange plate 10 and the return air plate 14 can be disposed at the bottom of the housing 1, and the return air cover 3 is also disposed at the bottom of the housing 1.

[0024] The return air cover 3 of this utility model is set between the fan cavity and the heat exchange cavity, which on the one hand increases the return air volume of the fan cavity, and on the other hand avoids the loss of airflow in the heat exchange cavity, which leads to a decrease in heat exchange efficiency.

[0025] The return air cover 3 includes a first side wall 4, a second side wall 5 and a third side wall 6. One side of the second side wall 5 is connected to the side wall of the heat exchange chamber through the first side wall 4, and the other side is provided with the third side wall 6, so that the return air cover 3 forms a C-shaped structure, thereby forming a pipe cavity 13 inside.

[0026] The return air cover 3 of this utility model forms a C-shaped structure through the connection of the first, second and third side walls, which improves the bending strength, transportation stability and resistance to deformation of the shell 1, effectively prevents the middle of the shell 1 from collapsing, and at the same time, the passage of the duct 13 is also conducive to the smooth return air.

[0027] The return air cover 3 also includes a fourth side wall 7, one side of which is connected to the third side wall 6 and the other side is connected to the side wall of the fan cavity. The third side wall 6 is provided with a plurality of auxiliary return air passages 15.

[0028] Preferably, but not limitingly, the auxiliary return air vent 15 can be honeycomb-shaped or circular, with a diameter of three to four millimeters, and multiple auxiliary return air vents 15 can be arranged side by side or staggered along the length direction.

[0029] This invention connects the auxiliary return air passage 15 on the third side wall 6 to the fan cavity, enabling auxiliary return air to be provided through the auxiliary return air passage 15 when the fan returns air, thereby increasing the return air area, reducing fan speed, noise, and improving user comfort. At the same time, since the auxiliary return air passage 15 is only provided on the third side wall 6, the airflow in the heat exchange cavity will not be lost, increasing the return air volume while ensuring heat exchange efficiency.

[0030] like Figure 4 As shown, the return air cover 3 further includes a reinforcing fold 8, and the return air cover 3 is connected to the housing 1 through the reinforcing fold 8.

[0031] The return air cover 3 can be provided with a reinforcing fold 8 on any side wall, and the reinforcing fold 8 is connected to the side plate 9 on the housing 1.

[0032] The return air cover 3 of this utility model is connected to the shell 1 by strengthening the folded edge 8, which further improves the bending strength and overall strength of the shell 1, and improves the connection stability between the return air cover 3 and the shell 1.

[0033] The working principle of this utility model is as follows: the fan 2 is started, so that the fan cavity returns air through the fan 2. One side of the fan cavity returns air through the air inlet 12, and the other side returns air through the auxiliary return air passage 16 to achieve bidirectional return air; the airflow in the fan cavity flows to the heat exchange cavity after returning air through the fan 2; the airflow flows out from the air outlet 11 after heat exchange in the heat exchange cavity.

[0034] Embodiment 2 of this utility model discloses an air conditioner, including the aforementioned ducted air conditioner.

[0035] The beneficial effect of this utility model is that, compared with the prior art, This utility model features a fan cavity with air return through an air inlet on one side and auxiliary air return through an auxiliary air return vent on the other side, achieving bidirectional air return. This significantly increases the air return area and air volume, better meeting the air return needs in different scenarios and improving heat exchange efficiency. At the same time, by increasing the air return volume, the fan speed is prevented from being too high, improving the fan's durability and operational stability, reducing equipment noise, and enhancing the user experience.

[0036] The return air cover of this utility model is set between the fan cavity and the heat exchange cavity, which on the one hand increases the return air volume of the fan cavity, and on the other hand avoids the loss of airflow in the heat exchange cavity, which would reduce the heat exchange efficiency.

[0037] The return air cover of this utility model forms a C-shaped structure through the connection of the first, second and third side walls, which improves the bending strength, transportation stability and resistance to deformation of the shell, and effectively prevents the middle of the shell from collapsing.

[0038] This invention connects the auxiliary return air passage on the third side wall to the fan cavity, allowing auxiliary return air to be assisted when the fan returns air, thereby increasing the return air area, which in turn reduces the fan speed, reduces noise, and improves user comfort. At the same time, because the auxiliary return air passage is only provided on the third side wall, the airflow in the heat exchange cavity will not be lost, which increases the return air volume while ensuring heat exchange efficiency.

[0039] The return air cover of this utility model improves the bending strength and overall strength of the shell by strengthening the connection between the folded edge and the shell, and improves the connection stability between the return air cover and the shell.
