Description

Technical Field

[0001] The present invention relates to the field of air conditioners, and in particular to a ceiling air conditioner. Background Art

[0002] In the prior art, the ceiling air conditioner is installed on the ceiling in a vertical state, which makes it difficult to clean its evaporator and other components. If it is not cleaned for a long time, the evaporator heat exchange efficiency may be poor, affecting the user experience. It is also easy for bacteria to grow on the surface of the evaporator, affecting the user's health.

[0003] In addition, the central divergent ribs of the ceiling machine chassis are mostly in the same plane. It is not easy to ensure the flatness of the plane when the reinforcing ribs are formed, and the strength is relatively poor; the motor of the ceiling machine fan is usually directly fixed to the chassis by installing bolts, which will cause resonance noise and affect the user experience. Summary of the invention

[0004] The problem solved by the present invention is that in the prior art, the evaporator in the ceiling fan is not easy to clean. If it is not cleaned for a long time, the evaporator heat exchange efficiency is likely to be poor, affecting the user experience. It is also easy for bacteria to grow on the surface of the evaporator, affecting the health of the user.

[0005] To solve the above problems, the present invention discloses a ceiling machine, including a chassis and a shell, wherein the chassis is connected to the shell to form a accommodating cavity, and the accommodating cavity is at least used to set an evaporator. At least one opening that can communicate with the outside of the ceiling machine is provided on the shell, and the opening can be opened or closed, and the opening is arranged corresponding to the evaporator for cleaning the evaporator when the opening is opened.

[0006] By setting the opening on the shell, when the user needs to clean the evaporator, he only needs to open the opening to expose the evaporator and perform the corresponding operation. Lateral foam for forming an air duct is arranged between the evaporator and the shell. In order to ensure that the wind passing through the evaporator enters the air duct, an air outlet is arranged on the lateral foam. The opening is arranged corresponding to the air outlet, so that when the opening is opened, the evaporator can be directly contacted through the air outlet, which will not restrict the user's operation, greatly simplifies the operation steps of cleaning the evaporator, and improves the cleaning efficiency.

[0007] Furthermore, a lateral foam is provided between the evaporator and the shell, an air outlet is provided on the lateral foam, and the opening is provided corresponding to the air outlet.

[0008] The above arrangement can reduce the improvement of the existing structure. When the opening is opened, the evaporator can be cleaned through the air outlet, which is simple and convenient. Preferably, the opening and the air outlet are arranged near the chassis. Since the ceiling machine is suspended on the ceiling, the chassis is actually arranged at the uppermost side. The opening and the air outlet are arranged near the chassis so that the two correspond to the upper side of the evaporator. On the one hand, the wind resistance can be reduced, the air circulation efficiency inside the ceiling machine can be improved, and the noise can be reduced. On the other hand, when cleaning the evaporator, water can be added near the upper side of the evaporator to achieve top-down cleaning, thereby improving the cleaning effect.

[0009] Furthermore, a reinforcement ring is arranged near the center of the chassis, and the reinforcement ring protrudes toward the side where the evaporator is arranged. A plurality of reinforcement structures are also arranged on the chassis, and the first ends of the plurality of reinforcement structures are connected to the reinforcement ring, and the second ends of the plurality of reinforcement structures are radially connected to the periphery of the chassis.

[0010] Since heavier components such as fans and evaporators usually need to be installed on the chassis, it is necessary to ensure sufficient structural strength. The reinforcement ring and the reinforcement structure can significantly improve the strength of the chassis to ensure the smooth support and installation of the above-mentioned components. The reinforcement ring is used to set the fan. In addition to strengthening the strength of the chassis, the reinforcement structure can also be used to set other installation structures. The above structure is simple and can be produced by mold pressing, which is easy to process, thereby improving production efficiency.

[0011] Furthermore, a groove is provided in the reinforcement ring, the groove is recessed toward a side away from the evaporator, a first connecting portion and a second connecting portion are provided on the groove, the first connecting portion and the second connecting portion protrude toward a side where the evaporator is provided, and the first connecting portion and the second connecting portion are used to connect to a motor of a fan in a ceiling machine.

[0012] In the prior art, the motor of the fan is connected to the chassis by screws. When the strength of the chassis is insufficient, resonance noise is likely to occur between the motor and the chassis, seriously affecting the user experience. The present invention significantly increases the structural strength of the fan motor installation position without increasing the thickness of the chassis material through the reinforcement ring and the protrusions of the groove, the first connecting part and the second connecting part, thereby avoiding the generation of resonance noise and improving the user experience.

[0013] Furthermore, a wire groove extending toward the outside of the chassis is provided on the reinforcement ring, and the wire groove is used for arranging the wiring of the fan.

[0014] The wire trough is arranged close to the terminal mounting part, or the wire trough and the terminal mounting part are an integrated structure. Optionally, the wire trough is recessed to the side away from the evaporator. This arrangement can make room for the wiring of the fan without occupying too much space in the accommodating cavity. At the same time, the wire trough and the terminal mounting part are an integrated structure so that the two can reinforce each other, thereby further improving the strength of the two.

[0015] Furthermore, the reinforcement structure includes a first reinforcement portion and a second reinforcement portion, wherein the first reinforcement portion is arranged close to the outer side of the chassis, and the second reinforcement portion is arranged close to the reinforcement ring, and the second reinforcement portion protrudes toward one side of the evaporator relative to the first reinforcement portion.

[0016] This arrangement can improve the local strength of the reinforcement structure, thereby facilitating the arrangement of more components on the chassis. In addition, this arrangement eliminates the need for the reinforcement structure to remain in the same plane, thereby improving the molding strength while reducing the difficulty of molding.

[0017] Furthermore, the angle between the chassis and the evaporator inlet and outlet pipes is recorded as the pipeline angle, and a terminal mounting portion is provided between the two reinforcement structures corresponding to the pipeline angle, and the terminal mounting portion is used to fix the load-bearing docking terminal of the evaporator.

[0018] The bearing docking terminal is used to support the inlet pipe and / or outlet pipe of the evaporator. This arrangement allows the inlet and outlet pipes of the evaporator to be located at the same angle. Preferably, the water tray water pump is also arranged at the corresponding position of the pipeline angle, thereby making the structure of the ceiling machine more compact.

[0019] Furthermore, the three corners on the chassis corresponding to the bending position of the evaporator are recorded as bending angles, and two reinforcing structures are provided corresponding to each bending angle. An electric heating mounting part is provided between the two reinforcing structures corresponding to at least one bending angle, and the electric heating mounting part is used to fix the electric heater.

[0020] The chassis is usually a rectangular structure. In the prior art, the electric heater is usually arranged on a straight line segment between the two corners. This arrangement takes up a large space and forms a turbulence between the evaporator and the fan corresponding to the air outlet, affecting the heat exchange efficiency of the evaporator. Setting the electric heater near the corner of the chassis is equivalent to setting it at the bend of the evaporator. On the one hand, it can save space, and on the other hand, it can significantly improve the heat exchange efficiency of the evaporator, thereby improving the operation effect of the ceiling machine.

[0021] Furthermore, a third connection portion is provided on one of the reinforcement structures corresponding to each bending angle, and a fourth connection portion is provided between two reinforcement structures corresponding to each bending angle, and the third connection portion and the fourth connection portion are used for fixed connection with the fixing frame of the evaporator.

[0022] The fourth connection part protrudes toward the side where the evaporator is provided, and the third connection part protrudes or recesses toward the side where the evaporator is provided. This arrangement can adopt more protruding or recessed structures to connect with the fixing frame, which significantly enhances the connection strength between the chassis and the evaporator.

[0023] Furthermore, chassis foam is provided on one side of the chassis close to the evaporator, and a plurality of avoidance openings are provided on the chassis foam, wherein at least one avoidance opening is provided corresponding to the evaporator and is used for connecting the evaporator and the chassis.

[0024] The avoidance opening is also arranged corresponding to one or more of the fan motor, the electric heater and the bearing docking terminal, so as to facilitate the connection between the above components and the chassis. The chassis foam is used to avoid condensation on the chassis, thereby ensuring the stable operation of the ceiling machine.

[0025] Compared with the prior art, the ceiling machine of the present invention has the following advantages:

[0026] The present invention provides a closable or openable opening on the shell, so that the evaporator can be cleaned without disassembling the panel and other components, thereby improving the convenience of cleaning, ensuring the heat exchange efficiency of the evaporator, and improving the user experience. In addition, the reinforcement ring and the reinforcement structure on the chassis significantly improve the chassis strength, and the evaporator, the fan and the electric heater can be stably installed. The present invention has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] To make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0037] A ceiling machine according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] This embodiment provides a ceiling machine, such as Figure 1 to Figure 7 As shown, it includes a chassis 100 and a shell 200, the chassis 100 is connected to the shell 200 to form a accommodating cavity, the accommodating cavity is at least used to set the evaporator 500, and at least one opening 202 that can communicate with the outside of the ceiling machine is set on the shell 200, the opening 202 can be opened or closed, and the opening 202 is set corresponding to the evaporator 500, and is used to clean the evaporator 500 when the opening 202 is opened.

[0039] In the prior art, since the ceiling machine is suspended on the ceiling, if the evaporator 500 is to be cleaned, the panel or grille of the ceiling machine needs to be removed and then the corresponding operation is performed. In addition, since other structures such as the fan 300 are also provided inside the evaporator 500, the operating space for cleaning the evaporator 500 is small, and the operation is extremely inconvenient. In this embodiment, through the setting of the opening 202 on the shell 200, when the user needs to clean the evaporator 500, he only needs to open the opening 202 to expose the evaporator 500 to perform the corresponding operation. A lateral foam 400 for forming an air duct is provided between the evaporator 500 and the shell 200. In order to ensure that the wind passing through the evaporator 500 enters the air duct, an air outlet is provided on the lateral foam 400. The opening 202 is arranged corresponding to the air outlet, so that when the opening 202 is opened, the evaporator 500 can be directly contacted through the air outlet, which will not restrict the user's operation, greatly simplifying the operating steps of cleaning the evaporator 500 and improving the cleaning efficiency. It should be noted that the opening 202 that can be opened or closed means that a movable baffle (not shown in the drawings) is arranged at the position of the opening 202, and the baffle can close or open the opening 202. A handle is arranged on the baffle, and the handle is arranged on the outside of the shell 200, so that the user can pull the handle to open or close the opening 202. The baffle can also be controlled by an automatic opening and closing structure. Its specific driving device and structure can refer to the prior art and will not be limited or elaborated here.

[0040] As an embodiment of the present invention, Figure 4 As shown, a lateral foam 400 is provided between the evaporator 500 and the shell 200, and an air outlet is provided on the lateral foam 400, and the opening 202 is provided corresponding to the air outlet. The above-mentioned arrangement can reduce the improvement of the existing structure. When the opening 202 is opened, the evaporator 500 can be cleaned through the air outlet, which is simple and convenient. Preferably, the opening 202 and the air outlet are arranged at a position close to the chassis 100. Since the ceiling machine is suspended on the ceiling, the chassis 100 is actually arranged at the uppermost side. The opening 202 and the air outlet are arranged at a position close to the chassis 100 so that the two correspond to the upper side of the evaporator 500. On the one hand, the wind resistance can be reduced, the air circulation efficiency inside the ceiling machine can be improved, and the noise can be reduced. On the other hand, when cleaning the evaporator 500, water can be introduced at a position close to the upper side of the evaporator 500 to achieve top-down cleaning, thereby improving the cleaning effect.

[0041] As an embodiment of the present invention, Figure 1 , Figure 2As shown, a reinforcing ring 107 is provided at a position close to the center of the chassis 100, and the reinforcing ring 107 protrudes toward the side where the evaporator 500 is provided. A plurality of reinforcing structures 102 are also provided on the chassis 100, and the first ends of the plurality of reinforcing structures 102 are connected to the reinforcing ring 107, and the second ends of the plurality of reinforcing structures 102 are radially connected to the periphery of the chassis 100. Since the chassis 100 usually needs to be provided with heavier components such as the fan 300 and the evaporator 500, it is necessary to ensure sufficient structural strength. The reinforcing ring 107 and the reinforcing structure 102 can significantly improve the strength of the chassis 100 to ensure the smooth support and installation of the above components. The reinforcing ring 107 is used to install the fan 300, and the reinforcing structure 102, in addition to reinforcing the strength of the chassis 100, can also be provided with other installation structures for supporting and installing other components in the ceiling machine. The above structure is simple and can be produced by mold pressing, which is convenient for processing, thereby improving production efficiency. It should be noted that the reinforcement ring 107 may be in a circular, rectangular, or polygonal shape, preferably a circular shape.

[0042] As one of the preferred embodiments, Figure 1 As shown, a groove 1071 is provided in the reinforcement ring 107, and the groove 1071 is recessed toward a side away from the evaporator 500. A first connection portion 105 and a second connection portion 106 are provided on the groove 1071, and the first connection portion 105 and the second connection portion 106 protrude toward a side where the evaporator 500 is provided. The first connection portion 105 and the second connection portion 106 are used to connect with the motor of the fan 300 in the ceiling machine. In the prior art, the motor of the fan 300 is connected to the chassis 100 by screws. When the chassis 100 is not strong enough, resonance noise is likely to occur between the motor and the chassis 100, which seriously affects the user's experience. In this embodiment, by means of the reinforcement ring 107 and the protruding arrangement of the groove 1071, the first connection portion 105 and the second connection portion 106, the structural strength of the fan 300 motor installation position is significantly increased without increasing the material thickness of the chassis 100, thereby avoiding the generation of resonance noise and improving the user's experience.

[0043] As an embodiment of the present invention, Figure 1 , Figure 2As shown, the reinforcement structure 102 includes a first reinforcement portion 1021 and a second reinforcement portion 1022, wherein the first reinforcement portion 1021 is arranged close to the outer side of the chassis 100, and the second reinforcement portion 1022 is arranged close to the reinforcement ring 107, and the second reinforcement portion 1022 protrudes toward the side of the evaporator 500 relative to the first reinforcement portion 1021. This arrangement can improve the local strength of the reinforcement structure 102, thereby facilitating the arrangement of more components on the chassis 100, such as the electric heater 600, the wire buckle 700, etc. In addition, this arrangement makes it unnecessary for the reinforcement structure 102 to remain in the same plane, thereby reducing the difficulty of molding and improving the molding strength.

[0044] As an embodiment of the present invention, Figure 2 , Figure 7 As shown, the angle corresponding to the chassis 100 and the inlet and outlet pipes of the evaporator 500 is recorded as the pipeline angle, and a terminal mounting portion 109 is provided between the two reinforcing structures 102 corresponding to the pipeline angle, and the terminal mounting portion 109 is used to fix the load-bearing docking terminal 900 of the evaporator 500. The load-bearing docking terminal 900 is used to support the inlet pipe and / or outlet pipe of the evaporator 500. This setting makes the inlet and outlet pipes of the evaporator 500 positioned at the same angle. Preferably, the water tray water pump is also provided at the corresponding position of the pipeline angle, thereby making the structure of the ceiling machine more compact. In addition, the terminal mounting portion 109 is provided to support the inlet and outlet pipes of the evaporator 500, further improving the installation stability of the evaporator 500.

[0045] In this implementation, if Figure 2 , Figure 7As shown, the three corners on the chassis 100 corresponding to the bending position of the evaporator 500 are recorded as bending angles, and two reinforcing structures 102 are correspondingly arranged at each bending angle. An electric heating mounting portion 108 is arranged between the two reinforcing structures 102 corresponding to at least one bending angle, and the electric heating mounting portion 108 is used to fix the electric heater 600. In this embodiment, the electric heating mounting portion 108 includes screw holes respectively arranged on the two reinforcing structures 102, and at least one of the two screw holes is arranged on the second reinforcing portion 1022. It should be understood that the chassis 100 is usually a rectangular structure. In the prior art, the electric heater 600 is usually arranged on a straight line segment between two corners. This arrangement occupies a large space and forms a turbulent flow between the evaporator 500 and the fan 300 corresponding to the air outlet, which affects the heat exchange efficiency of the evaporator 500. Setting the electric heater 600 at a position close to the corner of the chassis 100 is equivalent to setting it at the bend of the evaporator 500. On the one hand, it can save space, and on the other hand, it can significantly improve the heat exchange efficiency of the evaporator 500, thereby improving the operation effect of the ceiling machine. As an embodiment of the present invention, an electric heating installation portion 108 is provided between the two reinforcement structures 102 corresponding to the three corners of the chassis 100. This arrangement can set three electric heaters 600 in the ceiling machine, thereby significantly improving the auxiliary heating capacity of the ceiling machine.

[0046] In this embodiment, if Figure 2 As shown, a third connection portion 1023 is provided on one of the reinforcement structures 102 corresponding to each bending angle, and a fourth connection portion 103 is provided between the two reinforcement structures 102 corresponding to each bending angle, and the third connection portion 1023 and the fourth connection portion 103 are used to be fixedly connected to the fixing frame (not shown in the drawings) of the evaporator 500. Among them, the fourth connection portion 103 protrudes toward the side where the evaporator 500 is provided, and the third connection portion 1023 protrudes or is recessed toward the side where the evaporator 500 is provided, which is specifically determined according to the structure of the evaporator 500 and the fixing frame, and will not be repeated or limited here. It should be understood that the reinforcement structures 102 arranged radially separate the chassis 100 into a plurality of flat plate portions 101, and the fourth connection portion 103 is arranged on the flat plate portion 101. This arrangement can adopt more protruding or recessed structures to connect with the fixing frame, which significantly enhances the connection strength between the chassis 100 and the evaporator 500.

[0047] As an embodiment of the present invention, Figure 7As shown, a chassis foam 800 is provided on one side of the chassis 100 close to the evaporator 500, and a plurality of avoidance openings 801 are provided on the chassis foam 800, and the avoidance openings 801 are at least provided corresponding to the evaporator 500, and are used for connecting the evaporator 500 with the chassis 100. The avoidance openings 801 are also provided corresponding to one or more of the fan 300 motor, the electric heater 600, and the bearing docking terminal 900, so as to facilitate the connection between the above components and the chassis 100. The chassis foam 800 is used to prevent condensation from occurring on the chassis 100, thereby ensuring the stable operation of the ceiling machine.

[0048] As some optional embodiments, Figure 7 As shown, a plurality of wire buckles 700 are also provided on the chassis 100, and the wire buckles 700 are provided corresponding to the avoidance openings 801. A wire buckle 700 is provided between two bending angles to facilitate the standard wiring of the ceiling machine and avoid affecting its operation.

[0049] As an embodiment of the present invention, Figure 3 , Figure 4 As shown, a plurality of mounting ears 201 are arranged on the periphery of the housing 200, and the mounting ears 201 are used to suspend the ceiling machine. In some embodiments, corresponding suspension bolts are arranged in the mounting ears 201, so that the ceiling machine is suspended on the ceiling.

[0050] In this embodiment, if Figure 1 , Figure 2 As shown, a wire groove 104 extending toward the outside of the chassis 100 is provided on the reinforcement ring 107, and the wire groove 104 is used to set the wiring of the fan 300. Preferably, the wire groove 104 is set corresponding to the pipe angle. As a more optimal solution, the wire groove 104 is set close to the terminal mounting portion 109, or the wire groove 104 and the terminal mounting portion 109 are an integrated structure. Optionally, the wire groove 104 is recessed toward the side away from the evaporator 500. This setting can make room for the corresponding wiring of the fan 300 without occupying too much space in the accommodating cavity. At the same time, the wire groove 104 and the terminal mounting portion 109 are an integrated structure so that the two can reinforce each other, thereby further improving the strength of the two.

[0051] In the prior art, the chassis 100 is usually a metal sheet and is produced by mold pressing. However, since more components need to be arranged on the chassis 100, more connecting parts and mounting parts are arranged, and more bolts are arranged, which results in the need to perform corresponding stretching, blanking, bolt welding, tapping and other processes on the metal sheet during production. The manufacturing process is cumbersome, resulting in high production costs. Therefore, as a preferred embodiment, the chassis 100 is a plastic injection molded part, and the bolts are molded by insert molding, which can significantly reduce the production process, improve production efficiency, and reduce production costs. Due to the arrangement of more reinforcing structures 102 on the chassis 100, it is sufficient to ensure that the chassis 100 made of plastic material has the corresponding structural strength, so that the corresponding ceiling machine components can be safely and stably arranged, while ensuring the safety of the ceiling machine, reducing its production cost and improving its production efficiency.

[0052] It should be noted that the ceiling machine also includes conventional parts of the ceiling machine such as an air guide plate and an air inlet grille, and their specific structure and connection relationship can refer to the existing technical solutions, which will not be limited or elaborated here.
