Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, for example, to a ceiling-mounted air conditioner. Background Art

[0002] At present, most household air conditioners are wall-mounted or cabinet-type. Cabinet-type air conditioners take up a large space and have high requirements for the size of the house. Wall-mounted air conditioners are generally installed on the wall. In order to ensure the air inlet and outlet of the wall-mounted air conditioner, there is a gap between the top of the wall-mounted air conditioner and the ceiling, which makes the installation of the wall-mounted air conditioner more abrupt and leads to a poor sense of integration with the home decoration.

[0003] A related patent provides a ceiling-mounted air conditioner, which includes an air-conditioning shell, a bottom of which is formed a first air inlet, and a side wall of which is formed at least one second air inlet.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, the ceiling-mounted air conditioner sets the air inlet at the bottom and side wall, so that the ceiling-mounted air conditioner can be abutted against the ceiling when installed, improving the sense of integration after the ceiling-mounted air conditioner is installed. However, the air inlet of the ceiling-mounted air conditioner in the related patent is a hollow structure, so dust is easily accumulated at the air inlet, affecting the air intake, and further affecting the normal operation of the ceiling-mounted air conditioner.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0010] The ceiling-mounted air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0011] The ceiling-mounted air conditioner of the disclosed embodiment has an air inlet disposed on the bottom wall of the ceiling-mounted air conditioner housing, so that there is no need for air inlet at the top of the ceiling-mounted air conditioner. In this way, no space needs to be reserved at the top when the ceiling-mounted air conditioner is installed, and the ceiling-mounted air conditioner can be installed on the ceiling or suspended ceiling, which can not only reduce the installation space of the ceiling-mounted air conditioner, but also improve the sense of integration of the ceiling-mounted air conditioner with home decoration, and solve the pain points of wall-mounted air conditioner installation. An air inlet guide plate is disposed at the air inlet, and the air inlet guide plate can be rotated forward or backward to open or close the air inlet, so that when the ceiling-mounted air conditioner is not working, the air inlet can be closed to prevent dust from entering the air inlet and affecting the air intake.

[0033] Combination Figures 1 to 10 As shown, an embodiment of the present disclosure provides a ceiling-mounted air conditioner, which includes a shell 10, and the shell 10 defines a accommodating cavity 103 with an air inlet 101 and an air outlet 102. The air inlet 101 is arranged on the bottom wall of the shell 10, and the air outlet 102 is arranged on the front side wall 108 of the shell 10.

[0034] In the disclosed embodiment, the air inlet 101 of the ceiling-mounted air conditioner is arranged on the bottom wall of the shell 10, and the air outlet 102 is arranged on the front side wall 108 of the shell 10. In this way, the top wall 107 of the ceiling-mounted air conditioner can be set against the ceiling or the suspended ceiling, and no space needs to be reserved on the top of the ceiling-mounted air conditioner, which improves the aesthetics of the installation of the ceiling-mounted air conditioner and the sense of integration with the home decoration.

[0035] Optionally, the air inlet 101 is located at the rear side of the bottom wall of the shell 10 , so that the airflow flows in from the rear side of the shell 10 and then flows through the heat exchanger 201 , thereby improving the heat exchange effect with the heat exchanger 201 .

[0036] Optionally, the air outlet 102 is located on the front side wall 108 of the housing 10, so that the air outlet 102 does not occupy the top wall 107 of the housing 10, avoiding affecting the installation of the air conditioner. Moreover, the air outlet 102 is arranged on the front side wall 108 of the housing 10, which facilitates the air conditioner to discharge air forward and increases the air outlet area.

[0037] Optionally, the ceiling air conditioner further includes a temperature control component, which includes a fan 202 and a heat exchanger 201 and is located in the accommodating cavity 103 . The fan 202 can drive the air flow from the air inlet 101 through the heat exchanger 201 and then out of the air outlet 102 .

[0038] In the disclosed embodiment, the temperature control component is located in the accommodating cavity 103, and the fan 202 can drive the air flow at the air inlet 101 to flow through the heat exchanger 201, and flow out from the air outlet 102 after heat exchange with the heat exchanger 201, so that the air conditioner can blow out cold air or hot air to adjust the indoor temperature.

[0039] Optionally, the fan 202 is a cross-flow fan, which can increase the air volume of the air conditioner and thus improve the temperature control effect.

[0040] Optionally, the length of the cross-flow fan extends along the length direction of the housing 10 to reduce the dimensions of the air conditioner in other directions and facilitate the installation of the air conditioner.

[0041] Optionally, there are multiple cross-flow fans, and at least two of the multiple cross-flow fans are sequentially arranged along the length direction of the housing 10 .

[0042] In the disclosed embodiment, there are multiple crossflow fans, which can not only increase the air volume of the crossflow fans, but also increase the size of the ceiling air conditioner and the installation flexibility of the ceiling air conditioner. The opening and closing of each crossflow fan can also be independently controlled to increase the diversity of the air output of the ceiling air conditioner and improve the user experience.

[0043] Optionally, along the direction from back to front, the air inlet 101, the heat exchanger 201, the fan 202 and the air outlet 102 are arranged in sequence.

[0044] In the disclosed embodiment, the airflow flowing into the air inlet 101 first exchanges heat with the heat exchanger 201, then flows through the fan 202, and then flows out from the air outlet 102. The air inlet 101, the heat exchanger 201, the fan 202, and the air outlet 102 are arranged in sequence from the back to the front, that is, the air inlet 101 is arranged at the back, so that the airflow flowing into the air inlet 101 has enough path to flow through the heat exchanger 201, thereby increasing the heat exchange time with the heat exchanger 201 and improving the heat exchange efficiency.

[0045] Optionally, along the direction from front to back, the heat exchanger 201 is arranged to be tilted upward, and a part of the evaporator is located above the air inlet 101 .

[0046] In the disclosed embodiment, the heat exchanger 201 is tilted to increase the heat exchange area between the heat exchanger 201 and the airflow, thereby improving the temperature adjustment effect of the ceiling air conditioner. Part of the evaporator is located above the air inlet 101, so that the airflow flowing into the air inlet 101 can flow to the heat exchanger 201, further increasing the heat exchange area between the heat exchanger 201 and the air inlet 101.

[0047] Optionally, along the direction from top to bottom, the projection of the heat exchanger 201 is located inside the air inlet 101, and the upper end of the heat exchanger 201 abuts against the top wall 107 of the shell 10, so that the airflow flowing into the air inlet 101 must flow through the heat exchanger 201 and then flow to the air outlet 102, ensuring that the airflow flowing into the air inlet 101 can fully exchange heat, thereby improving the temperature control effect of the ceiling air conditioner.

[0048] Optionally, the height of the accommodating cavity 103 decreases from the back to the front. Since the air outlet 102 is arranged on the front side wall 108 and the air inlet 101 is arranged on the rear side of the bottom wall, the flow area of ​​the accommodating cavity 103 decreases as it approaches the air outlet 102, which can increase the air outlet speed of the air outlet 102. In addition, the area of ​​the air outlet 102 is reduced, which is also convenient for setting the air outlet device.

[0049] Optionally, the bottom wall of the shell 10 extends in a horizontal direction, and the distance between the top wall 107 of the shell 10 and the bottom wall of the shell 10 gradually decreases from the back to the front, so that the components in the shell 10 can be placed stably and the accommodating cavity 103 can be changed.

[0050] Optionally, the ceiling air conditioner also includes a driving device, which is located on one side of the crossflow fan and is used to drive the crossflow fan to rotate; wherein the number of the driving devices is the same as the number of the crossflow fans and corresponds one to one.

[0051] In the disclosed embodiment, each cross-flow fan is provided with a driving device, so that each cross-flow fan can be independently controlled to open or close or rotate speed, which can improve the air outlet diversity of the ceiling-mounted air conditioner.

[0052] Optionally, there are multiple air outlets 102, and the number of air outlets 102 is the same as the number of cross-flow fans and corresponds one to one.

[0055] In the disclosed embodiment, the volute 2021 is located above the crossflow fan, and the volute 2021 is located on one side of the crossflow fan, so that the volute 2021 and the volute tongue form a fan 202 cavity, and the fan 202 cavity is equipped with a crossflow fan. The volute 2021 and the volute tongue cooperate with the crossflow fan to adjust the air outlet direction of the crossflow fan, so that the airflow can flow from the rear side of the crossflow fan to the front side. One side of the volute 2021 extends to the side of the crossflow fan facing the heat exchanger 201, so that the heat exchanger 201 flowing out can flow into the fan 202 cavity, and then pass through the inside of the crossflow fan, and flow out from the lower part of the crossflow fan along the radial direction of the crossflow fan, so that the airflow flowing out of the crossflow fan can flow out from the air outlet 102. Since the bottom wall of the shell 10 extends horizontally, the distance between the top wall 107 of the shell 10 and the bottom wall of the shell 10 gradually decreases from the back to the front, and the outlet of the cross-flow fan is inclined downward from the back to the front, so that the outlet of the cross-flow fan can cooperate with the air outlet 102, thereby increasing the air output of the air outlet 102 and reducing the loss of air volume.

[0056] Optionally, the ceiling air conditioner further comprises reinforcing ribs, which are arranged on the side of the volute 2021 away from the cavity of the fan 202. This can improve the strength of the volute 2021 and prevent the volute 2021 from deforming.
