Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and particularly relates to an air duct assembly and a cabinet air conditioner. Background Art

[0002] Based on the existing distributed air supply cabinet air conditioner, in order to further improve the problem of heating comfort, an air duct capable of blowing air upward and downward is adopted. Correspondingly, in terms of the structural layout, the air outlets are arranged at the head and bottom of the whole machine.

[0003] In terms of the specific assembly method, in the prior art, the air duct assembly and the two sides of the air inlet panel are fixed with multiple screws, the base and the two sides of the air inlet panel are fixed with multiple screws, the rear side of the base and the rear side of the air inlet panel are fixed with screws, and the bottom of the chassis and the bottom of the air inlet panel are fixed with multiple screws. After the two are fixed, the chassis can pull the air inlet panel to prevent it from tipping backward; the bottom of the chassis and the base are fixed with multiple screws. After the two are fixed, the base presses on the chassis; the upper wind deflector and the two sides of the air duct assembly are fixed with multiple screws, the upper end of the lower wind deflector is fixed with 1 screw to the upper wind deflector, and the lower end is fixed to the base with multiple screws on both sides respectively.

[0004] Analyzing the above assembly method, it can be seen that in the overall machine frame layout of the prior art, it is mainly divided into an upper section and a lower section: among which the upper section is mainly the air duct assembly and the upper wind deflector. After the two are assembled, they are regarded as a whole with a large weight and are mainly borne on the upper part of the air inlet panel; the lower section is mainly the base and the lower wind deflector. After the two are assembled, they are regarded as a whole and are fastened to the lower end and the rear side of the air inlet panel with screws. Subsequently, the base and the air inlet panel are respectively fixed to the chassis component with screws. The weight of the lower section is mainly borne on the lower end of the air inlet panel and the chassis component.

[0005] The above assembly structure of the prior art results in:

[0006] (1) Except for being respectively fixedly lapped with the air inlet panel, the upper section and the lower section are only connected and fastened by 1 screw of the upper wind deflector and the lower wind deflector. From the overall frame layout, there is a lack of sufficient connection structure between the two to support the weight of the upper section, resulting in a large load on the upper section of the air inlet panel, deformation, and the whole machine tilting forward (abbreviation: forward tilt), and it is easy to shake back and forth. The forward tilt of the whole machine will further cause: when the fan components on the air duct assembly, the upper fan component and the lower fan component operate, the air duct assembly becomes the vibration source of the whole machine. And because the center of gravity of the upper section is at a relatively high height, it is easy to cause the whole machine to shake, resulting in mutual friction between the components and generating abnormal noises, affecting the user experience.

[0007] (2) The forward inclination of the upper part will cause the load to be transferred from the lower windshield to the support frame (chassis) of the chassis components, resulting in the support frame (chassis) being pressed and slightly deformed downward. There are 4 roller assemblies arranged around the chassis components to support the left and right air-sweeping devices at the bottom of the floor-standing air conditioner. Among them, 2 roller assemblies are arranged on the support frame (chassis). When the support frame (chassis) is deformed by the applied load, the 2 roller assemblies will sink locally, resulting in unstable operation of the left and right air-sweeping devices.

[0008] (3) The air duct assembly is assembled with the base component, and there will be a gap between the two components. In this way, when the air conditioner is turned on in the cooling mode, cold air will escape from the assembly gap into the air cavity of the air duct. When the cold air blows onto the external decorative panel, condensed water will form on the outer surface of the decorative panel, affecting the appearance. Especially when the condensed water slides down to the floor, it will bring a poor experience or even potential safety hazards to the user. Summary of the Invention

[0009] Therefore, the technical problem to be solved by the present invention is to provide an air duct assembly and a floor-standing air conditioner. The integrally formed volute and the integrally formed volute cover are assembled together to form the air duct assembly. The bottom of the air duct assembly is connected to the chassis of the floor-standing air conditioner, eliminating the need for the base component in the prior art. While simplifying the structure of the air conditioner, the structural strength of the air duct assembly is improved, effectively preventing the forward inclination of the air duct assembly, and further preventing the air conditioner from shaking and making abnormal noises.

The volute and the volute cover are respectively formed by an integrated molding method, and the volute and the volute cover are connected as a whole to form an air conditioner air duct between the opposite sides of the volute and the volute cover. The bottom end of the volute and / or the volute cover is connected to the chassis component of the floor-standing air conditioner.

An upper fan mounting hole is formed on the volute, and an upper fan air inlet corresponding to the upper fan mounting hole is formed on the volute cover.

[0027] Referring to Figures 1 to 5 As shown, according to an embodiment of the present invention, there is provided an air duct assembly for a cabinet air conditioner, which includes a volute 1 and a volute cover 2. The volute 1 and the volute cover 2 are respectively formed by an integral molding method, and the volute 1 and the volute cover 2 are connected (preferably detachably) together to form an air conditioner air duct between the opposite sides of the volute 1 and the volute cover 2. The bottom end of the volute 1 and / or the volute cover 2 is connected (preferably detachably) to the chassis component (not shown in the figure) of the cabinet air conditioner. In this technical solution, the integrally molded volute and the integrally molded volute cover are jointly assembled to form the air duct assembly. The bottom of the air duct assembly is detachably connected to the chassis of the cabinet air conditioner, and the existing base component is no longer used as the installation carrier. While simplifying the structure of the air conditioner, the structural strength of the air duct assembly is improved, effectively preventing the forward tilting of the air duct assembly, thereby preventing the air conditioner from shaking and making abnormal noises, and preventing the phenomenon of condensation on the decorative panel caused by air leakage through the gap between the air duct assembly and the base component in the prior art.

[0028] In some implementation manners, the air conditioner air duct includes an upper air duct 31 corresponding to the upper air outlet of the cabinet air conditioner. The volute 1 is provided with an upper fan mounting hole 11 for mounting the upper fan assembly 51. The volute cover 2 is provided with an upper fan air inlet 21 corresponding to the upper fan mounting hole 11. The upper air duct 31 is formed around the upper fan mounting hole 11 and / or the upper fan air inlet 21, that is, the upper air duct 31 can guide the pressure air flow generated by the upper fan assembly 51 to the upper air outlet. In some other implementation manners, the air conditioner air duct further includes a lower air duct 32 corresponding to the lower air outlet of the cabinet air conditioner. The volute 1 is further provided with a lower fan mounting hole 12. The volute cover 2 is provided with a lower fan air inlet 22 corresponding to the lower fan mounting hole 12. The lower air duct 32 is formed around the lower fan mounting hole 12 and / or the lower fan air inlet 22.

[0029] Furthermore, a middle air duct 33 is formed on one side of the lower fan mounting hole 12 close to the upper fan mounting hole 11 and / or on one side of the lower fan air inlet 22 close to the upper fan air inlet 21, and the middle air duct 33 guides part of the airflow of the lower fan assembly 52 installed in the lower fan mounting hole 12 to the upper air outlet, that is, at this time, part of the air outlet of the lower fan assembly 52 in the lower fan mounting hole 12 is guided to flow out from the upper air outlet via the middle air duct 33, and the other part is guided to flow out from the lower air outlet via the lower air duct 32. The design of this structure can adapt to The design of the external structure of the cabinet air conditioner, for example, the cabinet air conditioner at this time has a structure that is larger at the bottom and smaller at the top. On the one hand, it can make the placement of the air conditioner more reliable and stable, and on the other hand, it can make the appearance of the air conditioner more beautiful. When the cabinet air conditioner has a structure that is larger at the bottom and smaller at the top, the power of the lower fan assembly 52 can be greater than that of the upper fan assembly 51, so that the specifications and dimensions of the lower fan assembly 52 and the upper fan assembly 51 are adapted to the size of the air conditioner. At the same time, due to the use of the middle air duct 33, the air output of the upper fan assembly 51 with lower power can be effectively supplemented. Furthermore, a deflector 13 is constructed on the side of the volute 1 away from the volute cover 2, and the deflector 13 is arranged corresponding to the middle air duct 33. It can be understood that the side of the volute 1 away from the volute cover 2 will be assembled with a corresponding upper wind shield plate during specific application, so as to guide the airflow flowing out of the deflector 13 to the upper air outlet, and then be combined with the air outlet air flow of the upper fan assembly 51 to be blown out from the top air outlet of the cabinet air conditioner. Similarly, the side of the volute 1 away from the volute cover 2 will be assembled with a corresponding lower wind shield plate during specific application, so as to guide the airflow flowing out of the lower fan assembly 52 to be blown out from the bottom air outlet of the cabinet air conditioner.

[0030] Preferably, the volute 1 and the volute cover 2 are bolted, that is, connected by a plurality of bolts, and preferably the plurality of bolts are evenly spaced along the left and right sides of the volute 1 and / or the volute cover 2.

[0031] The connection structure specifically includes a plurality of threaded holes 41, and the arrangement positions of the plurality of threaded holes 41 correspond to the connection holes on the chassis component, so that a reliable connection can be achieved through the connection holes and the corresponding threaded holes 41. Preferably, the bottom end of the volute 1 and / or the volute cover 2 has a positioning structure, and the positioning structure is used to form an assembly positioning with the chassis component to facilitate the assembly process of the air duct component and the chassis component. For example, the positioning structure includes a latch 42, and the corresponding chassis component is provided with a corresponding socket.

[0032] According to an embodiment of the present invention, a cabinet air conditioner is further provided, including the above-mentioned air duct assembly. Specifically, as described above, the bottom end of the air duct assembly forms a reliable connection with the chassis assembly through the connection structure and the positioning structure. The volute cover 2 of the air duct assembly and the air inlet panel 6 are detachably connected by a plurality of bolts. It can be understood that a corresponding heat exchanger should also be provided between the volute cover 2 and the air inlet panel 6. At the same time, a decorative panel (not shown in the figure) is also provided opposite to the air inlet panel 6. The decorative panel and the air inlet panel are snap-connected. As a conventional design in the art, the present invention will not be elaborated.

[0033] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous ways can be freely combined and superimposed.

[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention.
