Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioners, in particular to a ceiling machine. BACKGROUND

[0002] In the prior art, the ceiling machine is arranged on the ceiling in a vertical state, which makes it difficult to clean the evaporator and other devices, and long-term non-cleaning can cause poor heat exchange efficiency of the evaporator, affecting the user experience, and bacteria can also breed on the surface of the evaporator, affecting the health of the user.

[0003] In addition, the center dispersion ribs of the ceiling machine chassis are mostly in the same plane, and the ribs in the same plane are not easy to guarantee the flatness of the plane during molding, and the strength is relatively poor; the motor of the ceiling machine fan is usually fixed on the chassis directly through mounting bolts, which can cause resonance noise, affecting the user experience. SUMMARY

[0004] The problem solved by the present application is that in the prior art, the evaporator in the ceiling machine is not easy to clean, and long-term non-cleaning can cause poor heat exchange efficiency of the evaporator, affecting the user experience, and bacteria can also breed on the surface of the evaporator, affecting the health of the user.

[0005] To solve the above problems, the present application discloses a ceiling machine, comprising a chassis and a shell, the chassis is connected with the shell, and is used to form a containing cavity, the containing cavity is used to arrange at least an evaporator, at least one opening capable of communicating with the outside of the ceiling machine is arranged on the shell, the opening is openable or closable, and the opening is arranged corresponding to the evaporator, and is used to clean the evaporator when the opening is opened.

[0006] Through the arrangement of the opening on the shell, when the user needs to clean the evaporator, the user only needs to open the opening to expose the evaporator and then perform the corresponding operation, the evaporator and the shell are provided with a lateral foam for forming an air duct, in order to ensure that the air passing through the evaporator enters the air duct, an air passage is arranged on the lateral foam, the opening is arranged corresponding to the air passage, so that the evaporator can be directly contacted through the air passage when the opening is opened, and the operation of the user is not limited, greatly simplifying the operation steps of cleaning the evaporator and improving the cleaning efficiency.

[0007] Further, a lateral foam is arranged between the evaporator and the shell, and an air passage is arranged on the lateral foam, and the opening is arranged corresponding to the air passage.

[0008] The above arrangement can reduce the improvement of the existing structure, and when the opening is opened, the evaporator can be cleaned through the air passage, which is simple and convenient. Preferably, the opening and the air passage are arranged close to the bottom disc. Since the ceiling machine is suspended on the ceiling, the bottom disc is actually arranged on the uppermost side. Arranging the opening and the air passage close to the bottom disc makes them correspond to the upper side of the evaporator. On the one hand, it can reduce air resistance, improve the circulation efficiency of air in the ceiling machine, and reduce noise. On the other hand, when cleaning the evaporator, water can be supplied close to the upper side of the evaporator to achieve top-down cleaning, thereby improving the cleaning effect.

[0009] Further, a reinforcing ring is arranged close to the center of the bottom disc, the reinforcing ring is protruded to one side of the evaporator, and a plurality of reinforcing structures are arranged on the bottom disc, first ends of the plurality of reinforcing structures are connected with the reinforcing ring, and second ends of the plurality of reinforcing structures are connected with the outer periphery of the bottom disc in a radial manner.

[0010] Since the bottom disc usually needs to be provided with heavy components such as a fan and an evaporator, it needs to ensure sufficient structural strength. The reinforcing ring and the reinforcing structure can significantly improve the strength of the bottom disc to ensure smooth support and installation of the above components. The reinforcing ring is used to set the fan, and the reinforcing structure can be provided with other mounting structures in addition to reinforcing the strength of the bottom disc. The above structure is simple and can be produced by die pressing, which is convenient for processing and improves production efficiency.

[0011] Further, a groove is arranged in the reinforcing ring, the groove is recessed to a side away from the evaporator, a first connecting part and a second connecting part are arranged on the groove, the first connecting part and the second connecting part are protruded to a side provided with the evaporator, and the first connecting part and the second connecting part are used to connect with a motor of the fan in the ceiling machine.

[0012] In the prior art, the motor of the fan is connected with the bottom disc by screws. When the strength of the bottom disc is insufficient, resonance noise may occur between the motor and the bottom disc, which seriously affects the user experience. The present application protrudes the reinforcing ring and the groove, the first connecting part and the second connecting part in the reinforcing ring, significantly increases the structural strength of the installation position of the motor of the fan without increasing the thickness of the bottom disc, avoids the generation of resonance noise, and improves the user experience.

[0013] Further, a wire groove extending to the outside of the bottom disc is arranged on the reinforcing ring, and the wire groove is used to set the wiring of the fan.

[0014] The wire slot is arranged close to the terminal mounting portion, or the wire slot and the terminal mounting portion are in an integrated structure. Optionally, the wire slot is recessed to a side away from the evaporator, which can provide corresponding wire space for the wiring of the fan, while occupying less space in the accommodation cavity. Meanwhile, the integrated structure of the wire slot and the terminal mounting portion can strengthen each other, thereby further improving the strength of both.

[0015] Further, the reinforcing structure includes a first reinforcing portion and a second reinforcing portion. The first reinforcing portion is arranged close to the outer side of the bottom plate, and the second reinforcing portion is arranged close to the reinforcing ring. The second reinforcing portion is protruded to the side of the evaporator relative to the first reinforcing portion.

[0016] This arrangement can improve the local strength of the reinforcing structure, thereby facilitating the arrangement of more components on the bottom plate. In addition, this arrangement allows the reinforcing structure to be arranged without being kept in the same plane, thereby reducing the difficulty of molding and improving the molding strength.

[0017] Further, an angle corresponding to the inlet and outlet pipes of the evaporator on the bottom plate is referred to as a pipe angle. A terminal mounting portion is arranged between two reinforcing structures corresponding to the pipe angle. The terminal mounting portion is used to fix a load-carrying butt joint terminal of the evaporator.

[0018] The load-carrying butt joint terminal is used to support the inlet pipe and / or the outlet pipe of the evaporator. This arrangement allows the inlet and outlet pipes of the evaporator to be arranged at the same angle. Preferably, a water pan pump is also arranged at a position corresponding to the pipe angle, thereby making the structure of the ceiling machine more compact.

[0019] Further, three angles on the bottom plate corresponding to the bending positions of the evaporator are referred to as bending angles. Two reinforcing structures are arranged at each bending angle. An electric heating mounting portion is arranged between the two reinforcing structures corresponding to at least one bending angle. The electric heating mounting portion is used to fix an electric heater.

[0020] The bottom plate is usually in a rectangular shape. In the prior art, the electric heater is usually arranged on a straight line segment between two angles. This arrangement occupies a large space and forms a disturbance between the evaporator corresponding to the air outlet and the fan, thereby affecting the heat exchange efficiency of the evaporator. Arranging the electric heater close to the angle of the bottom plate is equivalent to arranging it at the bending position of the evaporator. This arrangement can save space and significantly improve the heat exchange efficiency of the evaporator, thereby improving the operation effect of the ceiling machine.

[0021] Further, a third connecting portion is arranged on one of the reinforcing structures corresponding to each bending angle, and a fourth connecting portion is arranged between the two reinforcing structures corresponding to each bending angle. The third connecting portion and the fourth connecting portion are used to be fixedly connected with a fixing frame of the evaporator.

[0022] The fourth connecting part protrudes towards the side where the evaporator is arranged, and the third connecting part protrudes or is recessed towards the side where the evaporator is arranged, which can be connected with the fixing frame in a more protruding or recessed structure, thereby significantly enhancing the connecting strength between the chassis and the evaporator.

[0023] Further, the chassis is provided with a chassis foam on the side close to the evaporator, and a plurality of avoiding openings are arranged on the chassis foam, at least one of which is arranged correspondingly to the evaporator and used for connecting the evaporator and the chassis.

[0024] The avoiding openings are also arranged correspondingly to one or more of the fan motor, the electric heater and the bearing butt joint terminal, so as to facilitate the connection between the above components and the chassis. The chassis foam is used for avoiding condensation of the chassis, thereby ensuring stable operation of the ceiling machine.

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

[0026] According to the application, the evaporator can be cleaned without disassembling the panel and other components through the closable or openable opening in the shell, the convenience of cleaning is improved, the heat exchange efficiency of the evaporator is ensured, and the user experience is improved. In addition, the strength of the chassis is significantly improved through the setting of the reinforcing ring and the reinforcing structure on the chassis, and stable installation of the evaporator, the fan and the electric heater is realized. The application has simple structure and convenient operation. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only some, not all, of the embodiments of this invention. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

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

[0038] This embodiment provides a ceiling machine, such as Figures 1-7 As shown, the device includes a chassis 100 and a housing 200. The chassis 100 is connected to the housing 200 to form a receiving cavity. The receiving cavity is used to house at least an evaporator 500. At least one opening 202 is provided on the housing 200 to communicate with the outside of the ceiling machine. The opening 202 is openable or closed and is corresponding to the evaporator 500 for cleaning the evaporator 500 when the opening 202 is open.

[0039] In the prior art, if the ceiling machine is suspended on the ceiling, the panel or the grille of the ceiling machine needs to be disassembled for cleaning the evaporator 500, and other structures such as the fan 300 are arranged in the evaporator 500, so that the operation space of the evaporator 500 is small and the operation is extremely inconvenient. In the embodiment, the opening 202 is arranged on the shell 200, so that the user only needs to expose the evaporator 500 by opening the opening 202 when cleaning the evaporator 500. The lateral foam 400 is arranged between the evaporator 500 and the shell 200 to form an air duct. In order to ensure that the air passing through the evaporator 500 enters the air duct, the air passage is arranged on the lateral foam 400. The opening 202 is arranged corresponding to the air passage, so that the evaporator 500 can be directly contacted through the air passage when the opening 202 is opened, and the operation of the user is not limited, which greatly simplifies the operation steps of cleaning the evaporator 500 and improves 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 figure) is arranged at the position of the opening 202. The baffle can close or open the opening 202. A handle is arranged on the baffle. The handle is arranged outside the shell 200, which is convenient for the user to pull the handle to open or close the opening 202. The baffle can also be controlled by an automatic opening and closing structure. The specific driving device and structure can refer to the prior art, which will not be limited and described here.

[0040] As an embodiment of the present application, as shown in Figure 4 The lateral foam 400 is arranged between the evaporator 500 and the shell 200, and the air passage is arranged on the lateral foam 400. The opening 202 is arranged corresponding to the air passage. The above arrangement can reduce the improvement of the existing structure. When the opening 202 is opened, the evaporator 500 can be cleaned through the air passage. Preferably, the opening 202 and the air passage are arranged near the bottom disc 100. Since the ceiling machine is suspended on the ceiling, the bottom disc 100 is actually arranged at the uppermost side. Arranging the opening 202 and the air passage near the bottom disc 100 makes them correspond to the upper side of the evaporator 500. On the one hand, it can reduce the air resistance, improve the air circulation efficiency in the ceiling machine, and reduce the noise. On the other hand, when cleaning the evaporator 500, water can be supplied near the upper side of the evaporator 500 to realize top-down cleaning and improve the cleaning effect.

Since the bottom plate 100 usually needs to be arranged with heavy components such as the fan 300 and the evaporator 500, it is necessary to ensure sufficient structural strength, and the reinforcing ring 107 and the reinforcing structure 102 can significantly improve the strength of the bottom plate 100 to ensure the smooth support and installation of the above-mentioned components, the reinforcing ring 107 is used to arrange the fan 300, and the reinforcing structure 102 can be arranged with other mounting structures for supporting and installing other components in the ceiling machine in addition to reinforcing the strength of the bottom plate 100. The above-mentioned structure is simple and can be produced by mold pressing, which is convenient for processing and improves the production efficiency. It should be noted that the reinforcing ring 107 can be one of a circle, a rectangle, and a polygon, and is preferably a circle.

In the prior art, the motor of the fan 300 is connected with the bottom plate 100 through screws, when the strength of the bottom plate 100 is insufficient, resonance noise is easily generated between the motor and the bottom plate 100, which seriously affects the user experience, in the embodiment, the reinforcing ring 107 and the protruding arrangement of the groove 1071, the first connecting part 105 and the second connecting part 106 significantly increase the structural strength of the motor mounting position of the fan 300 without increasing the thickness of the bottom plate 100, avoid the generation of resonance noise, and improve the user experience.

[0043] As an embodiment of the present application, Figure 1 , Figure 2As shown, the reinforcing structure 102 comprises a first reinforcing portion 1021 and a second reinforcing portion 1022, the first reinforcing portion 1021 is arranged close to the outer side of the chassis 100, the second reinforcing portion 1022 is arranged close to the reinforcing ring 107, and the second reinforcing portion 1022 is protruded to the side of the evaporator 500 relative to the first reinforcing portion 1021. This arrangement can improve the local strength of the reinforcing structure 102, thereby facilitating the arrangement of more components on the chassis 100, such as the electric heater 600, the wire pressing buckle 700, etc., in addition, this arrangement makes the reinforcing structure 102 not need to be kept in the same plane, thereby reducing the difficulty of molding while improving the molding strength.

[0044] As an embodiment of the present application, as shown in Figure 2 、 Figure 7 The angle corresponding to the inlet and outlet pipes of the evaporator 500 on the chassis 100 is referred to as the pipe angle, and the terminal mounting portion 109 is arranged between the two reinforcing structures 102 corresponding to the pipe angle, and the terminal mounting portion 109 is used to fix the load butt terminal 900 arranged on the evaporator 500. The load butt terminal 900 is used to support the inlet pipe and / or outlet pipe arranged on the evaporator 500. This arrangement makes the inlet and outlet pipes of the evaporator 500 located at the same angle, and preferably, the water pump of the water pan is also arranged at the corresponding position of the pipe angle, thereby making the structure of the ceiling machine more compact. In addition, the arrangement of the terminal mounting portion 109 is used to support the inlet and outlet pipes arranged on the evaporator 500, thereby further improving the mounting stability of the evaporator 500.

[0045] In the present embodiment, as shown in Figure 2 、 Figure 7As shown, three corners of the chassis 100 corresponding to the bending positions of the evaporator 500 are marked as bending corners, and two reinforcing structures 102 are arranged at each bending corner. An electric heating mounting portion 108 is arranged between the two reinforcing structures 102 corresponding to at least one bending corner, and the electric heating mounting portion 108 is used to fix the electric heater 600.

It should be understood that the chassis 100 is generally rectangular in structure. In the prior art, the electric heater 600 is generally arranged on a straight line segment between two corners, which occupies a large space and forms a disturbance between the evaporator 500 corresponding to the air outlet and the fan 300, affecting the heat exchange efficiency of the evaporator 500. Arranging the electric heater 600 close to the corner of the chassis 100 is equivalent to arranging it at the bending position of the evaporator 500, which can save space and 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 application, the electric heating mounting portion 108 is arranged between the two reinforcing structures 102 corresponding to the three corners of the chassis 100, which can arrange three electric heaters 600 in the ceiling machine, thereby significantly improving the auxiliary heating capacity of the ceiling machine.

[0046] In the embodiment, as shown in the drawings, Figure 2 A third connecting portion 1023 is arranged on one of the reinforcing structures 102 corresponding to each bending corner, and a fourth connecting portion 103 is arranged between the two reinforcing structures 102 corresponding to each bending corner. The third connecting portion 1023 and the fourth connecting portion 103 are used to be fixedly connected with the fixing frame (not shown in the drawings) of the evaporator 500. The fourth connecting portion 103 protrudes towards the side where the evaporator 500 is arranged, and the third connecting portion 1023 protrudes or is recessed towards the side where the evaporator 500 is arranged. The specific structure is determined according to the structure of the evaporator 500 and the fixing frame, which will not be repeated and limited here. It should be understood that the reinforcing structures 102 arranged in a radial manner divide the chassis 100 into several plate portions 101, and the fourth connecting portion 103 is arranged on the plate portion 101. This arrangement can use more protruding or recessed structures to connect with the fixing frame, thereby significantly enhancing the connection strength between the chassis 100 and the evaporator 500.

[0047] As an embodiment of the present application, as shown in the drawings, Figure 7As shown in the drawings, the bottom plate 100 is provided with a bottom plate foam 800 on the side close to the evaporator 500, and a plurality of avoiding openings 801 are arranged on the bottom plate foam 800, the avoiding openings 801 are arranged at least in correspondence with the evaporator 500, and are used for connecting the evaporator 500 and the bottom plate 100. The avoiding openings 801 are also arranged in correspondence with one or more of the motor of the fan 300, the electric heater 600 and the bearing butt joint terminal 900, so as to facilitate the connection of the above components and the bottom plate 100. The bottom plate foam 800 is used for avoiding the condensation of the bottom plate 100, so as to ensure the stable operation of the ceiling machine.

[0048] As part of the optional embodiments, as shown in the drawings, Figure 7 As shown in the drawings, a plurality of wire pressing buckles 700 are arranged on the bottom plate 100, and the wire pressing buckles 700 are arranged in correspondence with the avoiding openings 801. One wire pressing buckle 700 is arranged between two bending angles, so as to facilitate the standard wiring of the ceiling machine and avoid affecting the operation thereof.

[0049] As part of the embodiments of the present application, as shown in the drawings, Figure 3 , Figure 4 As shown in the drawings, a plurality of mounting ears 201 are arranged on the outer periphery of the shell 200, and the mounting ears 201 are used for suspending the ceiling machine.

Alternatively, the wire passing groove 104 is recessed to the side away from the evaporator 500, which can leave corresponding wiring space for the wiring of the fan 300, and does not occupy much space of the accommodating cavity. At the same time, the wire passing groove 104 and the terminal mounting portion 109 are integrated, so as to mutually strengthen each other, thereby further improving the strength of the two.

[0051] In the prior art, the chassis 100 is usually a metal plate produced by die pressing, but since many components need to be arranged on the chassis 100, many connecting parts and mounting parts are arranged, and many bolts are arranged, so that the metal plate needs to be subjected to corresponding processes such as stretching, blanking, bolt welding and tapping during production, the manufacturing process is complicated, and the production cost is high. Therefore, as a preferred embodiment, the chassis 100 is a plastic injection molding part, and the bolt is integrally formed by embedding plastic, which can significantly reduce the production process, improve the production efficiency and reduce the production cost. Since the reinforcing structure 102 is arranged on the chassis 100, the chassis 100 made of plastic material has sufficient structural strength, so that the corresponding ceiling machine components can be safely and stably arranged, the production cost is reduced, and the production efficiency is improved under the condition of ensuring the safety of the ceiling machine.
