[0085] The bottom of the shell is in a normally open structure to form a mounting port, through which the heat exchanger, the fan and the water pan are assembled into the shell.

[0086] The ceiling type air conditioner further comprises a panel assembly, the panel assembly is provided with an air inlet and an air outlet, the panel assembly is arranged at the bottom of the shell and covers the mounting port, the air inlet is in communication with the air inlet channel,

[0087] In use, after the fan is running, under the action of the fan, external air enters the air inlet channel through the air inlet, after heat exchange with the heat exchanger, the air is transported to the air outlet direction through the air outlet channel, and finally, the heat-exchanged air is output to the indoor space through the air outlet.

[0088] In an embodiment of the present application, in order to increase the coverage range of the air supply, the panel assembly 4 is improved and designed as follows. As shown in Figures 1-6As shown, an embodiment of the ceiling type air conditioner provided by the present application comprises:

[0089] A housing 1, a bottom of the housing 1 forms a mounting port.

[0090] A heat exchanger 2, the heat exchanger 2 is configured to perform heat exchange treatment on the airflow flowing through, the heat exchanger 2 is arranged in the housing 1; a supply air passage is formed between the heat exchanger 2 and the inner wall of the housing 1, and the heat exchanger 2 surrounds the air inlet passage.

[0091] A fan 3, the fan 3 is located in the air inlet passage.

[0092] A panel assembly 4, the panel assembly 4 is arranged at the bottom of the housing 1.

[0093] The panel assembly 4 comprises: a mounting panel 41, a bottom of the mounting panel 41 is provided with an air inlet port 411 and a first air outlet port 412, a side of the mounting panel 41 is provided with a second air outlet port 413, and the first air outlet port 412 is arranged outside the air inlet port 411;

[0094] The panel assembly 4 comprises: an air deflector 42, the air deflector 42 is rotatably arranged in the first air outlet port 412;

[0095] The mounting panel 41 is arranged at the bottom of the housing 1 and covers the mounting port, the air inlet port 411 communicates with the air inlet passage, and the first air outlet port 412 communicates with the supply air passage;

[0096] The mounting panel 41 is provided with an air guide portion 414 between the first air outlet port 412 and the second air outlet port 413, and the air guide portion 414 is provided with a communication port 4141, and the communication port 4141 communicates with the supply air passage;

[0097] One side of the air guide portion 414 forms a first air outlet channel, the other side of the air guide portion 414 forms a second air outlet channel, the first air outlet port 412 communicates with the supply air passage through the first air outlet channel, and the second air outlet port 413 communicates with the communication port 4141 through the second air outlet channel.

[0098] Specifically, the panel assembly 4 in the present application forms an air outlet area arranged in an up-down manner on the mounting panel 41, air is outletted outward from the bottom of the mounting panel 41 through the first air outlet port 412, and air is outletted outward from the side of the mounting panel 41 through the second air outlet port 413.

[0099] The first air outlet 412 is arranged at the bottom of the air supply channel and directly communicates with the air supply channel, the first air outlet 412 and the second air outlet 413 are spaced apart by the air guide part 414, and the second air outlet 413 communicates with the air supply channel through the communication opening 4141 arranged on the air guide part 414.

[0100] The airflow after heat exchange through the heat exchanger 2 is conveyed downward in the air supply channel, and the airflow after heat exchange can directly blow out below the installation panel 41 through the first air outlet 412 at the bottom. At the same time, the airflow conveyed in the air supply channel flows to the air guide part 414 and can also be conveyed toward the second air outlet 413 direction through the communication opening 4141 to blow out outward through the second air outlet 413.

[0101] Since the second air outlet 413 blows air laterally and the airflow in the air supply channel flows vertically downward, in order to improve the air outlet speed of the second air outlet 413 to increase the coverage range of the airflow output by the second air outlet 413, the air outlet cross-sectional area of the second air outlet along the air outlet direction has a decreasing trend.

[0102] Specifically, during the air supply process, when it is needed to convey the airflow after heat exchange outward through the second air outlet 413, the air outlet area of the first air outlet 412 can be reduced or the first air outlet 412 can be closed through the air guide plate 42, so that the airflow conveyed by the air supply channel enters the second air outlet through the communication opening 4141.

[0103] Due to the decreasing trend of the air outlet cross-sectional area of the second air outlet, the flow rate of the airflow will increase during the flow of the airflow in the second air outlet, and finally the flow rate of the airflow output from the second air outlet 413 is large to increase the air outlet coverage range of the second air outlet 413.

[0104] By arranging the air guide part 414 on the installation panel 41, the air guide part separates the first air outlet 412 and the second air outlet 413, and the communication opening 4141 is arranged on the air guide part 414 to meet the communication of the second air outlet 413 with the air supply channel through the communication opening 4141, and the first air outlet and the second air outlet form the first air outlet and the second air outlet on both sides of the air guide part 414. For the second air outlet 413, the air outlet cross-sectional area of the second air outlet has a decreasing trend, so that the airflow flowing into the second air outlet through the communication opening 4141 can be accelerated to improve the air outlet speed of the second air outlet 413, thereby increasing the air supply range.

[0105] In an embodiment of the present application, the air guide part 414 extends outwardly and downwardly.

[0106] Specifically, for the air guide portion 414 arranged on the mounting panel 41, the air guide portion 414 is in an inclined extending state, the upper portion of the air guide portion 414 will extend to the lower outer edge of the air supply channel, and the lower portion of the air guide portion 414 will extend obliquely towards the outside.

[0107] In this way, after the airflow conveyed by the air supply channel flows to the bottom of the mounting panel 41, on the one hand, the airflow can be directly output from the first air outlet 412, and on the other hand, the airflow has a tendency to flow outward under the guidance of the air guide portion 414, thereby making it easier for part of the airflow to flow to the second air outlet 413 through the communication port 4141.

[0108] Furthermore, in the case where the first air outlet 412 and the second air outlet 413 are both in an open state for air supply outward, the second air outlet 413 can still have sufficient air volume supply to provide the air volume of the second air outlet 413, thereby greatly increasing the air supply coverage range of the second air outlet 413.

[0109] By arranging the air guide portion 414 on the mounting panel 41, the air guide portion separates the first air outlet 412 and the second air outlet 413, and the communication port 4141 is arranged on the air guide portion 414 to meet the second air outlet 413 communicating with the air supply channel through the communication port 4141. The air guide portion 414 extends obliquely outward from top to bottom, so that the airflow conveyed by the air supply channel can flow into the side of the air guide portion 414 close to the second air outlet 413 through the guidance of the air guide portion 414, so as to increase the air volume of the second air outlet 413, thereby increasing the air supply range.

[0110] In an embodiment, the communication port 4141 is arranged opposite to the second air outlet 413; the communication port 4141 is configured to convey the airflow towards the direction of the second air outlet 413.

[0111] Specifically, for the airflow flowing towards the direction of the second air outlet 413 through the communication port 4141, in order to reduce the air resistance of the airflow in the second air duct, the communication port 4141 and the second air outlet 413 are arranged in an opposite manner. In this way, after the airflow enters the communication port 4141, it can directly flow towards the direction of the second air outlet 413, so as to improve the air speed of the second air outlet 413.

[0112] The air communication hole 4141 is arranged opposite to the second air outlet 413, so that the air flow input from the air communication hole 4141 can directly flow towards the second air outlet 413, thereby improving the air outlet efficiency of the second air outlet 413. Especially in the case that the air deflector 42 closes the first air outlet 412, the air deflector 414 is used to guide the air flow output by the air supply channel to the air communication hole 4141, so that the air flow can more smoothly flow towards the second air outlet 413 through the air communication hole 4141.

[0113] In an embodiment, the air deflector 414 is further provided with a bending portion 4142 which is bent upwards and extends, and the edge of the bending portion 4142 and the mounting panel 41 form the second air outlet 413.

[0114] Specifically, in order to better guide the air flow to flow towards the second air outlet 413, for the air flow conveyed by the air supply channel to flow into the second air outlet through the air communication hole 4141, the flow direction of the air flow in the air supply channel and the air outlet direction of the second air outlet 413 are staggered. For the air flow entering the second air outlet through the air communication hole 4141, there is still a tendency to flow downward. Therefore, the air flow input through the air communication hole 4141 is guided to flow by forming the bending portion 4142 on the lower part of the air deflector 414.

[0115] The bending portion 4142 extends upwards at an angle towards the second air outlet 413, so as to guide the air flow to smoothly flow towards the second air outlet 413 through the bending portion 4142.

[0116] By additionally providing the bending portion 4142 which bends upwards and extends on the air deflector 414, the bending portion 4142 extends towards the second air outlet 413, so that the air flow conveyed through the air communication hole 4141 flows towards the second air outlet 413 under the guidance of the bending portion 4142, thereby further improving the air outlet efficiency of the second air outlet 413.

[0117] In an embodiment, a plurality of rib plates 415 are arranged side by side at the second air outlet 413, the rib plates 415 are vertically arranged, and the rib plates 415 are connected between the mounting panel 41 and the bending portion 4142.

[0118] Specifically, the second air outlet 413 on the mounting panel 41 is in a strip-shaped structure as a whole, in order to make the air outlet amount at different positions of the second air outlet 413 uniformly distributed, a plurality of rib plates 415 are sequentially arranged on the mounting panel 41 along the length direction of the second air outlet 413, the rib plates 415 can divide the air flow flowing into the second air outlet 413, so as to ensure that the air outlet amount at different positions of the second air outlet 413 remains substantially uniform.

[0119] By increasing the plurality of parallel arranged baffle plates 415 at the second air outlet 413, the airflow to the second air outlet 413 can be guided by the vertical arrangement of the baffle plates 415, and under the action of the plurality of baffle plates 415, the airflow output by the second air outlet 413 can be divided to ensure uniform distribution of the airflow output by the second air outlet 413.

[0120] In one embodiment of the present application, as shown in Figures 1-12 The ceiling type air conditioner comprises a shell 1, a heat exchanger 2, a fan 3 and a panel assembly 4.

[0121] The bottom of the shell 1 forms a mounting opening, the heat exchanger 2 is configured to perform heat exchange treatment on the airflow passing through, and the heat exchanger 2 is arranged in the shell 1; an air supply channel is formed between the heat exchanger 2 and the inner wall of the shell 1, the heat exchanger 2 surrounds the air supply channel, and the fan 3 is located in the air supply channel.

[0122] The panel assembly 4 comprises a mounting panel 41, the bottom of the mounting panel 41 is provided with an air inlet 411 and an air outlet portion, and the air outlet portion is annular and distributed on the outer side of the air inlet 411.

[0123] The air outlet portion is configured to communicate with the air supply channel and output the airflow after heat exchange via the heat exchanger 2 from the side and corner portions of the mounting panel 41, respectively.

[0124] Specifically, the mounting panel 41 is formed with the annular distributed air outlet portion around the air inlet 411, and the airflow after heat exchange supplied by the air supply channel can be output outward through the air outlet portion. Since the air outlet portion is annular in structure, the air outlet portion can supply the airflow after heat exchange outward from all directions of the mounting panel 41, thereby effectively increasing the coverage range of the air outlet to achieve 360-degree comprehensive air supply.

[0125] By forming the annular distributed air outlet portion on the mounting panel 41, during use, the airflow after heat exchange treatment by the heat exchanger 2 flows to the air outlet portion through the air supply channel, and the annular design of the air outlet portion allows the air outlet portion to output air outward at the side and corner portions of the mounting panel 41, so that the mounting panel 41 can output air outward in 360 degrees. Thus, the technical problem of small air supply coverage range caused by no air output at the corner position of the mounting panel 41 can be solved, and the air outlet portion can effectively increase the coverage range of the air outlet to improve the air supply effect of the ceiling type air conditioner.

[0126] In one embodiment, the side position of the mounting panel 41 is provided with a first air outlet 412, and the edge and corner positions of the mounting panel 41 are provided with auxiliary air outlets 416; a rotatable air guide plate 42 is arranged in the first air outlet 412;

[0131] The first air outlet 412 and the auxiliary air outlet 416 are respectively communicated with the air supply channel. In use, the airflow after heat exchange conveyed by the air supply channel can be respectively outputted through the first air outlet 412 and the auxiliary air outlet 416. Thus, the air supply can be realized at the side area and the corner area of the installation panel 41, and the air supply treatment can be realized at the four sides and the corners of the installation panel 41.

[0132] By increasing the auxiliary air outlet 416 at the corner of the installation panel 41, the auxiliary air outlet 416 is communicated with the air supply channel, and the airflow after heat exchange can be further outputted through the auxiliary air outlet 416, and the air supply can be realized at the corner area of the installation panel 41, which is more conducive to improving the coverage range of the air supply.

[0133] In an embodiment, the panel assembly 4 further comprises a grid cover plate 43 arranged on the installation panel 41 and covering the air inlet 411. The side of the grid cover plate 43 and the installation panel 41 form a first air outlet interval 401. The first air outlet 412 is arranged opposite to the corresponding first air outlet interval 401.

[0134] The panel assembly 4 further comprises a cover plate 44 shielding the outside of the auxiliary air outlet 416. The cover plate 44 and the installation panel 41 form a second air outlet interval 402.

[0135] The adjacent two first air outlet intervals 401 are communicated through the second air outlet interval 402 at the corresponding corner to form a ring-shaped air outlet part.

[0136] Specifically, the panel assembly 4 covers the air inlet 411 by the grid cover plate 43, and the first air outlet spacing 401 is formed between the grid cover plate 43 and the mounting panel 41, the first air outlet 412 outputs air flow outward through the first air outlet spacing 401, and the air deflector 42 is further arranged in the first air outlet spacing 401.

[0137] The auxiliary air outlet 416 is shielded by the cover plate 44, and the second air outlet spacing 402 is formed between the cover plate 44 and the mounting panel 41, and the air flow output by the auxiliary air outlet 416 is output outward through the second air outlet spacing 402.

[0138] The first air outlet spacing 401 and the second air outlet spacing 402 are in communication with each other, so that the air outlet portion surrounding the air inlet 411 is formed on the mounting panel 41, and 360-degree air outlet is realized.

[0139] By increasing the cover plate 44, the cover plate 44 can shield the auxiliary air outlet 416 at the corner position of the mounting panel 41, and under the action of the cover plate 44, the air flow output from the auxiliary air outlet 416 is not blown vertically but output from the edge of the cover plate, so that the corner of the mounting panel 41 can output air flow horizontally outward, which is more conducive to improving the coverage range of air outlet.

[0140] In an embodiment, the cover plate 44 is detachably arranged at the corresponding corner of the grid cover plate 43; or the cover plate 44 and the grid cover plate 43 are an integral structure.

[0141] Specifically, the cover plate 44 can be an independent component, or can be an integral structure with the grid cover plate 43.

[0142] For the cover plate 44 of the independent structure, it can be installed on the grid cover plate 43 by clamping or screw fixing and the like.

[0143] The cover plate 44 is detachably installed on the grid cover plate 43, which can facilitate the installation and removal of the cover plate 44 by the operator. By processing the grid cover plate 43 and the cover plate 44 as an integral structure, the process of installing the cover plate 44 can be saved, and the assembly efficiency is improved.

[0144] In an embodiment, the mounting panel 41 can be provided with a second air outlet 413 on the side portion to meet the requirement of air outlet on the side portion of the mounting panel 41. The structure design and air outlet mode of the second air outlet 413 can refer to the description in the above embodiment, which is not limited here.

[0145] In an embodiment, the ceiling type air conditioner further comprises a water collecting tray 5, which is annularly arranged in the installation opening and is located below the heat exchanger 2 and above the installation panel 41.

[0146] The corner of the water collecting tray 5 is provided with a first ventilation part 51, and the auxiliary air outlet 416 is communicated with the air supply channel through the first ventilation part 51.

[0147] Specifically, the water collecting tray 5 is arranged in the installation opening of the shell 1 and needs to meet the requirement of receiving the condensed water of the heat exchanger 2. Therefore, the water collecting tray 5 is annularly arranged, and the air inlet 411 and the first air outlet 412 are separated by the water collecting tray 5. In addition, the water collecting tray 5 needs to avoid the air inlet 411 to ensure that the air flow input by the air inlet 411 enters the air inlet channel, and the water collecting tray 5 is provided with the first ventilation part 51 at the corner to meet the requirement that the air flow in the air supply channel can flow to the auxiliary air outlet 416 through the first ventilation part 51, thereby meeting the requirement that the auxiliary air outlet 416 can smoothly output air.

[0148] By arranging the first ventilation part 51 on the water collecting tray 5, the water collecting tray 5 can realize the mutual communication between the auxiliary air outlet 416 and the air supply channel formed outside the heat exchanger 2 through the first ventilation part 51 arranged at the corner, thereby realizing that the air supply channel supplies the air flow after heat exchange to the auxiliary air outlet 416 through the first ventilation part 51 arranged on the water collecting tray 5, to ensure the smoothness of air supply.

[0149] In an embodiment, the side of the water collecting tray 5 is provided with a second ventilation part 52, and the first air outlet 412 and the second air outlet 413 are communicated with the air supply channel through the second ventilation part 52.

[0150] Specifically, since the water collecting tray 5 is located in the installation opening and separates the first air outlet 412 and the air inlet 411, the second ventilation part 52 is formed at the side of the water collecting tray 5, and the second ventilation part 52 avoids the first air outlet 412 and the second air outlet 413, to meet the requirement that the first air outlet 412 and the second air outlet 413 are communicated with the air supply channel.

[0151] By arranging the second ventilation part 52 at the side of the water collecting tray 5, the second ventilation part 52 can communicate the first air outlet 412 and the second air outlet 413 with the air supply channel, thereby ensuring the smoothness of air supply of the air supply channel.

[0152] In another embodiment of the present application, as shown in Figures 1-12 In order to avoid the condensation of the panel assembly 4, the panel assembly 4 is improved in structure as follows.

[0153] The panel assembly 4 comprises a mounting panel 41, a bottom of the mounting panel 41 is provided with an air inlet 411, side edges of the mounting panel 41 are provided with first air outlets 412; the mounting panel 41 is arranged at the bottom of the shell 1 and covers the mounting opening, the air inlet 411 is communicated with the air inlet channel, and the first air outlets 412 are communicated with the air supply channels;

[0154] The panel assembly 4 comprises a grating cover plate 43, the grating cover plate 43 is arranged on the mounting panel 41 and covers the air inlet 411, and a side portion of the grating cover plate 43 and the mounting panel 41 form first air outlet intervals 401, and the first air outlets 412 are arranged opposite to corresponding first air outlet intervals 401;

[0155] The panel assembly 4 comprises a cover plate 44, and the cover plate 44 and the mounting panel 41 form second air outlet intervals 402;

[0156] The first air outlet intervals 401 are communicated with adjacent second air outlet intervals 402, and the second air outlet intervals 402 are configured to output air flow towards corresponding corner portions of the mounting panel 41.

[0157] Specifically, during operation of the ceiling type air conditioner, air flow conveyed by the air supply channel flows through the first air outlets 412 and is outputted outwards through the first air outlet intervals 401. Since the first air outlet intervals 401 and the second air outlet intervals 402 are communicated with each other, part of the air flow is also expanded into the second air outlet intervals 402 and flows towards the edge corner direction of the mounting panel 41 from the edge of the cover plate 44 during output from the first air outlet intervals 401.

[0158] The air flow output from the second air outlet intervals 402 can blow towards the mounting panel 41, and the air flow can cover the surface of the edge corner portion of the mounting panel 41, so that condensation is reduced at the edge corner portion of the mounting panel 41 under the action of the air flow.

[0159] By arranging the cover plate 44 on the mounting panel 41, the second air outlet intervals 402 are formed between the cover plate 44 and the mounting panel 41 at the corner position, during use, the air flow output by the first air outlets 412 is outputted to the indoor environment through the first air outlet intervals 401, and the first air outlet intervals 401 are communicated with adjacent second air outlet intervals 402, so that part of the air flow output from the second air outlets 413 can also flow into the second air outlet intervals 402, and then flow towards the corner direction of the mounting panel 41 under the action of the second air outlet intervals 402, so that the air flow also flows through the corner position of the mounting panel 41, thereby reducing condensation at the corner position of the mounting panel 41 and improving user experience.

[0160] In an embodiment, the mounting panel 41 is further provided with a protruding flow guide 417 on the outer surface opposite to the cover plate 44; the flow guide 417 is configured to guide the airflow to flow from the second air outlet interval 402 towards the corner of the mounting panel 41.

[0161] Specifically, for the airflow flowing between the cover plate 44 and the mounting panel 41, in order to guide the airflow to be evenly dispersed after being output from the second air outlet interval 402 towards the corner of the mounting panel 41.

In this way, the airflow will be evenly dispersed under the action of the flow guide 417, and the corner of the mounting panel 41 can be better covered.

[0162] By forming the flow guide 417 on the surface of the mounting panel 41 opposite to the cover plate 44, the airflow output from the auxiliary air outlet 416 can be guided to be output from the edge of the cover plate 44 via the flow guide 417. The flow guide 417 can guide the airflow to flow smoothly, so as to improve the uniformity of the airflow distribution.

[0165] By forming the recess on the mounting panel 41 opposite to the cover plate 44, the airflow can be buffered between the recess and the cover plate 44, and the airflow can be guided to be evenly output in cooperation with the flow guide 417, so as to improve the anti-condensation processing capability of the corner of the mounting panel 41.

[0166] In an embodiment, the recess is formed in an arc-shaped concave surface.

[0167] Specifically, by designing the recess in an arc-shaped concave surface, the arc-shaped concave surface has small wind resistance and is more conducive to guiding the airflow to flow, so as to improve the smoothness of the airflow output.

[0168] In an embodiment, the corner of the mounting panel 41 is provided with an auxiliary air outlet 416, and the auxiliary air outlet 416 is in communication with the air supply channel.

[0174] In use, the airflow output from the auxiliary air outlet 416 can be diverged to the flow guide parts 417 to make the second air outlet interval 402 uniformly output the airflow, so as to more comprehensively cover the corners of the mounting panel 41 with the airflow.

[0175] By arranging the flow guide parts 417 in a radial distribution on the mounting panel 41, the plurality of flow guide parts 417 cooperate to guide the airflow to be uniformly output from the edge of the cover plate 44, so as to improve the uniformity of the airflow distribution at the corner area of the mounting panel 41.
