Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioner. Background Art

[0002] At present, wide-area air-supply air conditioners are provided with a front air outlet at the front end of the housing and side air outlets at both ends of the housing to achieve multi-directional air supply and wide-area air supply. However, the side air outlets and front air outlets of existing wide-area air-supply air conditioners can usually only be opened or closed at the same time, so that users cannot choose a single air outlet mode or a multi-directional air outlet mode according to their needs. Summary of the invention

[0003] The problem solved by the invention is: how to make the multi-directional air outlet of the air conditioner selective.

[0004] In order to solve the above-mentioned problems, the present invention provides an air conditioner, comprising a shell, a heat exchanger arranged in the shell, a cross-flow fan blade assembly and a guide mechanism; a front air outlet is provided at one end of the shell in the width direction; and the heat exchanger is located on the side of the cross-flow fan blade assembly away from the front air outlet; a side air outlet is provided at the end of the shell in the length direction, and the guide mechanism is arranged at the intersection of the air duct between the side air outlet and the front air outlet, and is suitable for opening or closing the side air outlet.

[0005] Therefore, the air conditioner has a richer air outlet mode and air outlet direction by setting the front air outlet and the side air outlet, and makes the air supply direction and angle of the air conditioner wider, so that the air conditioner can supply air in multiple directions and over a wide area. Moreover, by setting a guide mechanism at the wind channel fork between the side air outlet and the front air outlet to control the side air outlet of the air conditioner, the convenience of opening and closing the side air outlet of the air conditioner is improved, and the multi-directional air outlet of the air conditioner is made selectable and controllable, so that the user can choose a single air outlet mode or a multi-directional air outlet mode according to the needs, thereby improving the user experience.

[0006] Optionally, an upper air inlet and a lower air inlet are respectively provided at two ends of the shell in the vertical direction, and the heat exchanger is located between the upper air inlet and the lower air inlet.

[0007] Therefore, an upper air inlet and a lower air inlet are provided on the shell of the air conditioner, and the heat exchanger is arranged between the upper air inlet and the lower air inlet; in this way, the air inlet area of ​​the air conditioner is increased, so that the air conditioner can have a larger air inlet volume, so as to improve the heat exchange effect of the heat exchanger of the air conditioner and ensure the air output of the air conditioner.

[0008] Optionally, the crossflow blade assembly includes a first crossflow blade, a second crossflow blade and a blade motor, the blade motor is arranged between the first crossflow blade and the second crossflow blade, and the blade motor, the first crossflow blade and the second crossflow blade are coaxially arranged.

[0009] Therefore, the fan blade motor, the first crossflow fan blade and the second crossflow fan blade are preferably coaxially arranged. On the one hand, this is used to ensure uniform air output of the air conditioner; on the other hand, when the air conditioner only has one fan blade motor for driving the fan blade to rotate, the coaxial arrangement of the fan blade motor, the first crossflow fan blade and the second crossflow fan blade facilitates the control of the first crossflow fan blade and the second crossflow fan blade by the fan blade motor, so as to ensure that the first crossflow fan blade and the second crossflow fan blade can rotate synchronously.

[0010] Optionally, the fan blade motor is located at a middle position in the shell, and the first crossflow fan blade and the second crossflow fan blade are symmetrically arranged relative to the fan blade motor.

[0011] Therefore, the first crossflow fan blade and the second crossflow fan blade are symmetrically arranged relative to the fan blade motor, and preferably the first crossflow fan blade and the second crossflow fan blade have the same specifications to ensure that the air outlet rate or air volume at the left end and the right end of the front air outlet is the same, that is, the air outlet at the front air outlet is uniform, so as to improve the user experience and facilitate the maintenance and replacement of the first crossflow fan blade or the second crossflow fan blade, thereby reducing the maintenance and replacement cost of the first crossflow fan blade or the second crossflow fan blade.

[0012] Optionally, the air conditioner further comprises an air guide mechanism disposed at the front air outlet and / or the side air outlet, and the air guide mechanism is suitable for adjusting the air outlet angle of the front air outlet and / or the side air outlet.

[0013] Therefore, the air guide mechanism is arranged at the front air outlet and / or the side air outlet, and is used to adjust the air outlet angle of the air conditioner at the front air outlet and / or the side air outlet, so that the air conditioner is suitable for sweeping air up and down and / or left and right at the front air outlet, and / or sweeping air up and down and / or front and back at the side air outlet. In this way, the air outlet mode of the air conditioner is further enriched, and the air outlet mode of the air conditioner has the advantages of being humanized, intelligent, selectable and controllable, thereby improving the user experience.

[0014] Optionally, the front air outlet includes a first front air outlet and a second front air outlet, and the setting positions of the first front air outlet and the second front air outlet correspond to the positions of the first cross-flow fan blade and the second cross-flow fan blade respectively; the air guide mechanism includes a first air guide structure and a second air guide structure, and the first air guide structure and the second air guide structure are respectively arranged at the first front air outlet and the second front air outlet.

[0015] Therefore, the first front air outlet and the second front air outlet correspond to the first cross-flow fan blade and the second cross-flow fan blade respectively, so as to avoid interference between the airflow in the shell blown to the first front air outlet through the first cross-flow fan blade and the airflow blown to the second front air outlet through the second cross-flow fan blade, so as to optimize the air duct diversion of the air conditioner and facilitate the realization of multiple air outlet modes of the air conditioner; the first front air outlet and the second front air outlet are respectively provided with the first air guide structure and the second air guide structure to respectively control the air outlet angles at the first front air outlet and the second front air outlet, so that the air conditioner has multiple air outlet modes.

[0016] Optionally, the air guide mechanism also includes a first air guide motor and a second air guide motor, the first air guide motor is suitable for driving the first air guide structure to rotate to adjust the air outlet angle at the first front air outlet, the second air guide motor is suitable for driving the second air guide structure to rotate to adjust the air outlet angle at the second front air outlet, and the first air guide motor and the second air guide motor are arranged in parallel.

[0017] Therefore, the first air guide motor and the second air guide motor are suitable for independent control, so that the first air guide plate and the second air guide plate are independently controlled, further enriching the air outlet mode of the air conditioner, and making the air outlet mode of the air conditioner humanized, intelligent, selectable and controllable, thereby improving the user experience.

[0018] Optionally, the first air guide structure includes a first air guide plate and / or a second air guide plate, the first air guide plate is suitable for adjusting the air outlet angle at the first front air outlet in the vertical direction, and the second air guide plate is suitable for adjusting the air outlet angle at the first front air outlet in the length direction of the first front air outlet.

[0019] Therefore, the first air guide plate is used to adjust the air outlet angle of the air conditioner at the first front air outlet in the up and down directions, and the second air guide plate is used to adjust the air outlet angle of the front air outlet in the length direction of the first front air outlet, thereby enriching the air outlet mode of the air conditioner.

[0020] Optionally, the air guide mechanism includes a wind shield component and an air guide component, the wind shield component is suitable for opening or closing the side air outlet, and the air guide component is suitable for guiding the airflow flowing toward the air guide component to be blown out from the side air outlet and / or the front air outlet when the wind shield component opens the side air outlet.

[0021] Therefore, when the side air outlet of the air conditioner is closed, the air flow in the shell is blown out from the front air outlet only; when the side air outlet of the air conditioner is opened, the air flow in the shell is blown out from both the front air outlet and the side air outlet. In this way, the air flow is blown out from the side air outlet and the front air outlet under the guiding action of the guide component, so as to realize the active air supply from the side air outlet, thereby diversifying the functions of the air conditioner and making it convenient for users to choose one-way air outlet or multi-directional air supply according to actual needs.

[0022] Optionally, the wind shield assembly includes a wind shield plate and a motor suitable for being arranged in the shell, the wind shield plate having a closed position and an open position, and the motor is suitable for driving the wind shield plate to switch between the closed position and the open position; when the wind shield plate is in the closed position, the wind shield plate is suitable for blocking the side air outlet; when the wind shield plate is in the open position, the wind shield plate is suitable for opening the side air outlet to connect the side air outlet with the external space of the air conditioner.

[0023] Therefore, by setting a motor to drive the wind shield to switch between the closed position and the open position, thereby opening or closing the side air outlet, the multi-directional air outlet of the air conditioner is made selective and controllable, enriching the air outlet mode of the air conditioner.

[0024] Optionally, the wind shield includes a wind shield portion and a connecting rod portion, the wind shield portion is suitable for shielding the side air outlet, the connecting rod portion is connected to the motor, and the motor is suitable for driving the wind shield portion to rotate around the axis of the connecting rod portion so that the wind shield is located in the closed position or the open position.

[0025] Thus, the air guide mechanism drives the connecting rod part to rotate through the motor to drive the wind shield part to rotate around the axis of the connecting rod part to close or open the side air outlet, thereby improving the convenience of opening and closing the side air outlet of the air conditioner.

[0026] Optionally, the windshield assembly further comprises a sleeve sleeved on the connecting rod portion, the sleeve is provided with a limiting structure, and the limiting structure is suitable for cooperating with the windshield portion to limit the rotation angle of the windshield plate.

[0027] Therefore, the sleeve is used to limit the wind shield part and the connecting rod part in a direction perpendicular to the rotation direction of the wind shield part, so as to ensure that the wind shield part and the connecting rod part can stably rotate between the closed position and the open position; and a limiting structure is provided on the sleeve, which is suitable for cooperating with the wind shield part to limit the rotation angle of the wind shield plate, so as to avoid the situation where the wind shield part obstructs the air outlet of the front air outlet or causes damage to the guide mechanism due to excessive rotation.

[0028] Optionally, the guide assembly includes a first guide plate arranged in the shell; one end of the first guide plate is connected to the shaft sleeve, and the other end extends toward the side air outlet and is connected to the shell; the first guide plate is suitable for guiding the airflow flowing toward the first guide plate to be blown out from the side air outlet when the wind deflector is in the open position.

[0029] Therefore, the shaft sleeve is arranged on the first guide plate, so that the first guide plate and the wind shield are rotatably connected through the shaft sleeve to ensure that the wind shield can be rotated smoothly, so that the wind shield can be smoothly switched between the closed position and the open position; the other end of the first guide plate is connected to the shell to ensure the tightness of the connection between the first guide plate and the shell.

[0030] Optionally, the guide assembly also includes a second guide plate, one end of which is connected to the sleeve or the first guide plate, and the other end extends toward the front air outlet of the air conditioner and is connected to the shell; the second guide plate is suitable for guiding the airflow flowing toward the second guide plate to be blown out from the front air outlet.

[0031] Thus, the end of the second guide plate away from the connection with the shell is connected to the sleeve or the first guide plate, so that when the wind shield is in the open position, the side of the wind shield and the first guide plate facing the side air outlet is suitable for guiding the airflow flowing to the guide mechanism to be blown out from the side air outlet; when the wind shield is in the closed position, the side of the wind shield and the first guide plate facing the fan blade is suitable for guiding the airflow flowing to the guide mechanism to be blown out from the front air outlet. The guide mechanism guides the airflow, avoiding the airflow directly colliding with the inner wall of the shell and generating a large noise.

[0032] Optionally, the side air outlet includes a left air outlet and a right air outlet respectively arranged at both ends in the length direction of the shell; the two air guide mechanisms are respectively arranged at the wind duct fork between the left air outlet and the front air outlet, and at the wind duct fork between the right air outlet and the front air outlet; and the motors of the two air guide mechanisms are arranged in parallel.

[0033] Therefore, a left air outlet is provided at the left end of the shell, and a right air outlet is provided at the right end of the shell, so that the air conditioner can simultaneously discharge air from the front, the left side and the right side, so as to further enrich the air outlet mode of the air conditioner and make the air outlet direction and angle of the air conditioner wider; two guide mechanisms are set to respectively control the opening or closing of the left air outlet and the right air outlet, and the motors of the two guide mechanisms are arranged in parallel, which enriches the air outlet mode of the air conditioner and makes the multi-directional and wide-area air outlet of the air conditioner have the advantages of selectability and controllability.

DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "high", "low", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and a coordinate system XYZ is set herein, wherein the positive direction of the X-axis represents the front, the reverse direction of the X-axis represents the back, the positive direction of the Y-axis represents the right, the reverse direction of the Y-axis represents the left, the positive direction of the Z-axis represents the top, and the reverse direction of the Z-axis represents the bottom; these are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0044] Combination Figure 1-Figure 4As shown, an embodiment of the present invention provides an air conditioner, comprising a shell 1, a heat exchanger 5 arranged in the shell 1, a crossflow fan blade assembly 4 and a guide mechanism 2; a front air outlet 13 is provided at one end of the shell 1 in the width direction; the heat exchanger 5 is located on the side of the crossflow fan blade assembly 4 away from the front air outlet 13; a side air outlet 14 is provided at the end of the shell 1 in the length direction, and the guide mechanism 2 is arranged at the intersection of the air duct between the side air outlet 14 and the front air outlet 13, and is suitable for opening or closing the side air outlet 14.

[0045] In this embodiment, the housing 1 of the air conditioner is used to protect and accommodate the crossflow fan blade assembly 4, the heat exchanger 5 and the guide mechanism 2 of the air conditioner. The two ends of the housing 1 in the width direction are the front end and the rear end of the housing 1, respectively. Figure 1 X-axis direction; the front end of the housing 1 (i.e. the housing 1 is located at Figure 1 The front end of the housing 1 (i.e. the end of the housing 1 in the positive direction of the middle X axis) is provided with a front air outlet 13. Figure 1 The end opposite to the X-axis in the middle) is suitable for being directly connected to the installation surface (such as a wall) or connected through a bracket to install the air conditioner on the wall. The heat exchanger 5 is arranged between the rear end of the shell 1 and the crossflow fan assembly 4, that is, the heat exchanger 5 is rear-mounted in the shell 1 of the air conditioner; the two ends of the shell 1 in the length direction are the left end of the shell 1 (that is, the shell 1 is located at Figure 3 The end opposite to the Y axis) and the right end (i.e. the housing 1 is located Figure 3 The length direction of the housing 1 refers to the positive end of the Y axis. Figure 1 Y-axis direction; the left end of the housing 1 (i.e. the housing 1 is located at Figure 1 The end opposite to the Y axis in the middle) and / or the right end of the housing 1 (i.e., the housing 1 is located at Figure 1 The side air outlet 14 is provided at one end of the housing 1 in the positive direction of the middle Y axis, that is, in this embodiment, the side air outlet 14 can be provided at the left end of the housing 1, or at the right end of the housing 1, or both the left and right ends of the housing 1 can be provided with the side air outlet 14. By providing the front air outlet 13 and the side air outlet 14, on the one hand, the air outlet area of ​​the air conditioner is increased, so that the air conditioner is suitable for providing a larger air outlet volume to improve the heating or cooling effect of the air conditioner, thereby improving the user experience; on the other hand, the air outlet mode of the air conditioner is enriched, so that the air outlet direction and angle of the air conditioner are wider, and the dead angle of the air outlet of the air conditioner (that is, the position that the air flow blown by the air conditioner cannot directly reach) is reduced, further improving the user experience.

[0046] Different customers have different requirements for the air outlet direction of the air conditioner. For example, some customers only need to open the front air outlet 13, and the side air outlet 14 of the air conditioner does not need to be opened when in use, while some customers need to open both the front air outlet 13 and the side air outlet 14. Moreover, different customers have different requirements for the installation position of the wall-mounted air conditioner. For example, some customers need to install the left end of the air conditioner close to the left wall, and the air outlet on the left side of the air conditioner does not need to be opened when in use, while some customers need to install the right end of the air conditioner close to the right wall, and the air outlet on the right side of the air conditioner does not need to be opened when in use. However, the side air outlet 14 of the existing wall-mounted air conditioner capable of multi-directional air supply is usually opened or closed together with the front air outlet 13, that is, when the air conditioner is turned on, the side air outlet 14 is opened together with the front air outlet 13, and when the air conditioner is turned off, the side air outlet 14 is closed together with the front air outlet 13, making it impossible to choose whether to open the side air outlet 14 of the air conditioner or not according to the actual situation when the air conditioner is turned on, so it cannot meet the usage requirements of different customers.

[0047] In this embodiment, a guide mechanism 2 is provided at the wind channel junction between the side air outlet 14 and the front air outlet 13 to control the opening or closing of the side air outlet 14; wherein, the wind channel corresponding to the side air outlet 14 (i.e., the wind channel connected to the side air outlet 14) and the wind channel corresponding to the front air outlet 13 (i.e., the wind channel connected to the front air outlet 13) intersect, and the wind channel junction between the side air outlet 14 and the front air outlet 13 refers to the position where these two wind channels intersect, that is, the wind channel junction between the left air outlet 141 (described later) and the front air outlet 13 refers to the intersection position of the wind channel corresponding to the left air outlet 141 and the wind channel corresponding to the front air outlet 13, and the wind channel junction between the right air outlet 142 (described later) and the front air outlet 13 refers to the intersection position of the wind channel corresponding to the right air outlet 142 and the wind channel corresponding to the front air outlet 13. In this way, the guide mechanism 2 is arranged at the intersection of the wind channel between the front air outlet 13 and the side air outlet 14, rather than being arranged at the plane where the side air outlet 14 is located, so that the guide mechanism 2 can also divert the airflow while controlling the opening or closing of the side air outlet 14, so that the airflow can be better blown out from the front air outlet 13 and / or the side air outlet 14, thereby improving the air volume and air outlet effect of the air conditioner. Specifically, when the side air outlet 14 of the air conditioner is closed, the airflow in the shell 1 is blown out only from the front air outlet 13; when the side air outlet 14 of the air conditioner is opened, the airflow in the shell 1 is blown out from both the front air outlet 13 and the side air outlet 14; in this way, the multi-directional air outlet of the air conditioner is selectable and controllable, enriching the air outlet mode of the air conditioner; allowing users to choose a single air outlet mode or a multi-directional air outlet mode according to their needs, thereby improving the user experience.

[0048] In this way, by setting the front air outlet 13 and the side air outlet 14, the air outlet mode and air outlet direction of the air conditioner are enriched, and the air outlet direction and angle of the air conditioner are made wider, so that the air conditioner can discharge air in multiple directions and over a wide area. Moreover, by setting a guide mechanism at the wind channel fork between the side air outlet 14 and the front air outlet 13 to control the side air outlet of the air conditioner, the convenience of opening and closing the side air outlet 14 of the air conditioner is improved, and the multi-directional air outlet of the air conditioner is made selectable and controllable, so that the user can choose a single air outlet mode or a multi-directional air outlet mode according to the needs, thereby improving the user experience.

The blade motor 43 is arranged between the first crossflow blade 41 and the second crossflow blade 42, and the blade motor 43, the first crossflow blade 41 and the second crossflow blade 42 are coaxially arranged.

[0052] The fan motor 43, the first crossflow fan blade 41 and the second crossflow fan blade 42 are preferably coaxially arranged. On the one hand, they are used to ensure uniform air outlet of the air conditioner and avoid the situation where the air outlet rate or air volume of the air conditioner at the left and right ends of the front air outlet 13 is inconsistent when the distances between the first crossflow fan blade 41 and the second crossflow fan blade 42 are inconsistent, so as to ensure the user experience; on the other hand, when the air conditioner is provided with only one fan motor 43 for driving the fan blade to rotate, the fan motor 43, the first crossflow fan blade 41 and the second crossflow fan blade 42 are coaxially arranged, It facilitates the control of the fan motor 43 over the first crossflow fan blade 41 and the second crossflow fan blade 42 to ensure that the first crossflow fan blade 41 and the second crossflow fan blade 42 can rotate synchronously; the fan motor 43 is preferably arranged between the first crossflow fan blade 41 and the second crossflow fan blade 42, so that the fan motor 43 can simultaneously connect and drive the first crossflow fan blade 41 and the second crossflow fan blade 42 to ensure that the first crossflow fan blade 41 and the second crossflow fan blade 42 have the same rotation speed under the drive of the fan motor 43, that is, to ensure that the first crossflow fan blade 41 and the second crossflow fan blade 42 can rotate synchronously.

[0053] Furthermore, when the first crossflow blades 41 and the second crossflow blades 42 need to be independently controlled, the air conditioner can be provided with two drive motors, which are respectively used to drive the first crossflow blades 41 and the second crossflow blades 42 to rotate, so as to further enrich the air outlet mode of the air conditioner.

[0054] Optionally, combined Figure 3 , Figure 4 As shown, the fan motor 43 is located in the middle of the housing 1 , and the first cross-flow fan blades 41 and the second cross-flow fan blades 42 are symmetrically arranged relative to the fan motor 43 .
