Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly relates to an air conditioner. Background Art

[0002] At present, with the increasing improvement of living standards, air conditioners have become an indispensable household appliance in every household. Currently, the air deflector of a wall-mounted air conditioner is generally installed on the middle frame. If it is necessary to maintain or clean the components (such as cross-flow fans) inside the air deflector, the air deflector needs to be moved away first. During this process, if the air deflector is only slightly moved, the components inside cannot be completely exposed, affecting the maintenance or cleaning effect. If the air deflector is completely removed, the disassembly and assembly process is complex, time-consuming and laborious, and the maintenance or cleaning cycle is long, affecting the user experience. Content of the Utility Model

[0003] The problem solved by the utility model is how to achieve the displacement of the air deflector without completely removing the air deflector, prevent the air deflector from interfering with other components during the displacement process, facilitate the maintenance and cleaning of the components inside the air deflector, and effectively shorten the maintenance or cleaning cycle.

[0004] To solve the above problems, the technical solution of the utility model is realized as follows:

[0005] The utility model provides an air conditioner, including a face mask assembly, a base, a lower air duct, a middle frame, a first air deflector and a second air deflector. The lower air duct and the middle frame are both installed on the base. The face mask assembly is hinged to the middle frame. The first air deflector and the second air deflector are both rotatably installed on the face mask assembly, and the second air deflector is arranged inside the first air deflector. The second air deflector is used to always keep a gap with the middle frame and the lower air duct when the face mask assembly rotates and opens relative to the middle frame. Compared with the prior art, since the air conditioner provided by the utility model adopts the first air deflector and the second air deflector rotatably installed on the face mask assembly and the face mask assembly hinged to the middle frame, it can achieve the displacement of the air deflector without completely removing the air deflector, prevent the air deflector from interfering with other components during the displacement process, facilitate the maintenance and cleaning of the components inside the air deflector, and effectively shorten the maintenance or cleaning cycle.

[0006] Further, the lower air duct includes an upper guide plate, a lower guide plate and a connecting arm. The upper guide plate and the lower guide plate are arranged opposite to each other. The connecting arm is connected between the upper guide plate and the lower guide plate. An outlet is formed between the upper guide plate and the lower guide plate. The second air deflector partially extends into the outlet. The air flow blown out from the cross-flow fan can be blown outwards through the outlet. During the process that the face mask assembly drives the air deflector to rotate and open upwards relative to the middle frame, the air deflector will not interfere with the upper guide plate.

[0007] Furthermore, the mask assembly is extended with a support plate, which is supported by the upper guide plate and is used to separate from the upper guide plate when the mask assembly is rotated to open, so as to realize the displacement function of the mask assembly, thereby facilitating the user to maintain and clean the inner parts.

[0008] Furthermore, a side of the upper guide plate away from the outlet is provided with an escape groove, the escape groove has an end wall, the abutment plate partially extends into the escape groove and abuts against the end wall. The upper guide plate can limit the position of the mask assembly by abutting against the abutment plate and the end wall to limit the position of the mask assembly when it is in a closed state.

[0009] Furthermore, the middle frame is extended with a limit plate, the avoidance groove also has a side wall, the side wall is connected to the end wall, the side wall and the limit plate are relatively arranged on both sides of the end wall, and the abutment plate is arranged between the side wall and the limit plate. The side wall and the limit plate work together to limit the abutment plate, ensuring that the abutment plate can extend between the side wall and the limit plate and abut against the end wall when the abutment plate is rotated downward to close.

[0010] Furthermore, the mask assembly is extended with a positioning cantilever, and the second air guide door is provided with a matching protrusion, and the matching protrusion is rotationally matched with the positioning cantilever.

[0011] Furthermore, the middle frame is provided with a clearance gap, and the positioning cantilever is arranged in the clearance gap. The positioning cantilever is used to escape from the clearance gap when the mask assembly is rotated to open.

[0012] Furthermore, the mask assembly includes a panel, a first side panel, a second side panel and a bottom panel. The first side panel and the second side panel are relatively arranged on both sides of the panel and are both connected to the panel and the bottom panel. The first side panel and the second side panel are relatively arranged on both sides of the middle frame and are both rotatably connected to the middle frame. The bottom panel is arranged below the downwind duct and abuts against the downwind duct. The bottom panel is used to limit the downwind duct. When the mask assembly is rotated and opened relative to the middle frame, the bottom panel no longer limits the downwind duct. The user can easily remove the downwind duct, thereby facilitating maintenance and cleaning of the crossflow fan, which is convenient and quick.

[0013] Furthermore, the panel, the first side panel, the bottom panel and the second side panel are connected end to end and together form an air outlet, and the first air guide door and the second air guide door can be rotatably installed in the air outlet. The lower air duct is used to guide the outlet airflow blown out by the crossflow fan to the air outlet, and the air outlet is used to blow the outlet airflow into the room. The first air guide door and the second air guide door can both guide the outlet airflow, thereby realizing the function of adjusting the wind direction.

[0014] Furthermore, the mask assembly is provided with a buckle, and the middle frame is provided with a buckle hole, and the buckle is engaged with the buckle hole, so as to fix the relative position of the mask assembly and the middle frame when the mask assembly is in a closed state, prevent the mask assembly from accidentally detaching from the middle frame, and ensure the stability of the air conditioner during operation.

Detailed Description of the Invention

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of specific embodiments of the present utility model will be given with reference to the accompanying drawings.

[0027] First Embodiment

[0028] Please refer to Figures 1 to 6 , an embodiment of the present utility model provides an air conditioner 100 for regulating the indoor temperature. It can achieve the displacement of the air deflector without completely removing the air deflector, prevent the air deflector from interfering with other components during the displacement process, facilitate the maintenance and cleaning of the components inside the air deflector, and effectively shorten the maintenance or cleaning cycle.

[0029] It should be noted that the air conditioner 100 is a wall-mounted air conditioner. The air conditioner 100 is hung on the indoor wall. The air conditioner 100 is used to blow hot air or cold air into the room to achieve the functions of heating or cooling, thereby regulating the indoor temperature and meeting the needs of users.

[0030] The air conditioner 100 includes a face mask assembly 110, a base 160, a lower air duct 130, a middle frame 120, a cross-flow fan 140, and air guide vanes. The air guide vanes include a first air guide vane 151 and a second air guide vane 152. The cross-flow fan 140 is installed in the base 160, and the cross-flow fan 140 is used to realize the air outlet function of the air conditioner 100. Both the lower air duct 130 and the middle frame 120 are installed on the base 160. The lower air duct 130 is used to guide the air outlet flow blown by the cross-flow fan 140 to improve the air outlet effect, and the lower air duct 130 is also used to limit the cross-flow fan 140 to prevent the cross-flow fan 140 from detaching from the base 160. The first air guide vane 151 and the second air guide vane 152 are rotatably installed on the face mask assembly 110, and the second air guide vane 152 is arranged inside the first air guide vane 151. Both the first air guide vane 151 and the second air guide vane 152 are used to guide the air outlet flow to realize the function of adjusting the air direction. The first air guide vane 151 and the second air guide vane 152 work together to enhance the air supply effect and facilitate precise adjustment of the air direction. The face mask assembly 110 is hinged to the middle frame 120. The face mask assembly 110 can rotate and open relative to the middle frame 120 around the hinge point, and synchronously drive the first air guide vane 151 and the second air guide vane 152 to move, so that the components inside the face mask assembly 110, the first air guide vane 151, and the second air guide vane 152 are exposed, facilitating the user to maintain and clean the components inside. The second air guide vane 152 is used to always keep a gap with the middle frame 120 and the lower air duct 130 when the face mask assembly 110 rotates and opens relative to the middle frame 120, to prevent the middle frame 120 and the lower air duct 130 from interfering with the movement of the second air guide vane 152. Since the second air guide vane 152 is arranged inside the first air guide vane 151, the first air guide vane 151 also always keeps a gap with the middle frame 120 and the lower air duct 130 when the face mask assembly 110 rotates and opens, avoiding the middle frame 120 and the lower air duct 130 from interfering with the movement of the first air guide vane 151. In this way, the displacement of the air guide vanes can be realized without completely removing the air guide vanes, which is convenient, fast, time-saving and labor-saving, facilitating the maintenance and cleaning of the components inside the air guide vanes, and effectively shortening the maintenance or cleaning cycle.

[0031] In this embodiment, the face mask assembly 110 is hinged to the top of the middle frame 120, and the lower air duct 130 is installed at the bottom of the base 160. The face mask assembly 110 can be turned upwards relative to the middle frame 120 to synchronously drive the first air guide vane 151 and the second air guide vane 152 to move upwards, completely exposing the components located inside the face mask assembly 110 and the air guide vanes, and the face mask assembly 110, the first air guide vane 151, and the second air guide vane 152 will not interfere with the user's maintenance and cleaning.

[0032] The lower air duct 130 includes an upper guide plate 132, a lower guide plate 133, and a connecting arm 134. The upper guide plate 132 and the lower guide plate 133 are arranged opposite to each other. The connecting arm 134 is connected between the upper guide plate 132 and the lower guide plate 133. The connecting arm 134 is used to fix the relative positions of the upper guide plate 132 and the lower guide plate 133. The upper guide plate 132 and the lower guide plate 133 act together to guide the air flow blown out from the cross-flow fan 140.

[0033] Specifically, an outlet 131 is formed between the upper guide plate 132 and the lower guide plate 133. The air flow blown out from the cross-flow fan 140 can be blown outwards through the outlet 131. The second air guide door 152 partially extends into the outlet 131, that is, the second air guide door 152 is partially located inside the lower air duct 130. The second air guide door 152 can rotate relative to the lower air duct 130 to guide the air flow blown out from the lower air duct 130, so as to realize the function of adjusting the wind direction. During the process that the mask assembly 110 drives the second air guide door 152 to rotate upwards relative to the middle frame 120 around the hinge point to open, the second air guide door 152 will not interfere with the upper guide plate 132.

[0034] It can be understood that the top of the inner wall of the outlet 131 has a vertex, which is arranged on the upper guide plate 132. Taking the hinge point as the center and the distance between the hinge point and the vertex as the radius, a virtual circle is formed. The part of the second air guide door 152 extending into the outlet 131 is located outside the virtual circle. That is, during the process that the mask assembly 110 drives the second air guide door 152 to rotate upwards relative to the middle frame 120 around the hinge point to open, the part of the second air guide door 152 extending into the outlet 131 will not interfere with the top of the inner wall of the outlet 131, so as to prevent interference between the second air guide door 152 and the lower air duct 130 when the mask assembly 110 rotates and opens, and further prevent interference between the second air guide door 152 and other components during the displacement process, ensuring the reliability of the rotation and opening of the mask assembly 110 and strong safety.

[0035] For the convenience of understanding, the hinge point is denoted as a and the vertex is denoted as b.

[0036] In this embodiment, the mask assembly 110 is extended with a holding plate 111. The holding plate 111 abuts against the upper guide plate 132. The upper guide plate 132 is used to limit the mask assembly 110 through the holding plate 111, so as to define the position of the mask assembly 110 when it is in the closed state. The holding plate 111 is used to separate from the upper guide plate 132 when the mask assembly 110 rotates and opens, so as to facilitate the displacement function of the mask assembly 110, thereby facilitating the user to maintain and clean the inner components.

[0037] Further, an avoidance groove 135 is formed on the side of the upper guide plate 132 away from the outlet 131. The avoidance groove 135 is used to accommodate a part of the abutting plate 111 to save occupied space. Specifically, the avoidance groove 135 has an end wall 136. The abutting plate 111 partially extends into the avoidance groove 135 and abuts against the end wall 136. The upper guide plate 132 can limit the face mask assembly 110 through the abutment of the abutting plate 111 and the end wall 136 to define the position of the face mask assembly 110 when it is in the closed state.

[0038] Preferably, the middle frame 120 is extended with a limiting plate 121, and the limiting plate 121 is arranged on the side of the upper guide plate 132 away from the outlet 131. The avoidance groove 135 further has a side wall 137. The side wall 137 is connected to the end wall 136 and is perpendicular to the end wall 136. The side wall 137 and the limiting plate 121 are oppositely arranged on both sides of the end wall 136. The abutting plate 111 is arranged between the side wall 137 and the limiting plate 121. The side wall 137 and the limiting plate 121 act together to limit the abutting plate 111 to ensure that the abutting plate 111 can extend between the side wall 137 and the limiting plate 121 and abut against the end wall 136 when rotating downward to close. Specifically, the side of the limiting plate 121 close to the side wall 137 is chamfered, and the side of the side wall 137 close to the limiting plate 121 is chamfered to realize the guiding and sliding function of the abutting plate 111 and ensure that the abutting plate 111 can stably extend into the avoidance groove 135 and abut against the end wall 136.

[0039] The face mask assembly 110 includes a panel 112, a first side plate 113, a second side plate 114 and a bottom plate 115. The first side plate 113 and the second side plate 114 are oppositely arranged on both sides of the panel 112, are both connected to the panel 112, and are both connected to the bottom plate 115. The first side plate 113 and the second side plate 114 are oppositely arranged on both sides of the middle frame 120 and are both rotatably connected to the middle frame 120. The middle frame 120 is arranged between the first side plate 113 and the second side plate 114, that is, the face mask assembly 110 covers the outside of a part of the middle frame 120 to facilitate the rotation and opening of the face mask assembly 110. The bottom plate 115 is arranged below the lower air duct 130 and abuts against the lower air duct 130. The bottom plate 115 is used to limit the lower air duct 130. After the face mask assembly 110 rotates and opens relative to the middle frame 120, the bottom plate 115 no longer limits the lower air duct 130, and the user can easily remove the lower air duct 130, so as to facilitate the maintenance and cleaning of the cross-flow fan 140, which is convenient and fast. Specifically, the first side plate 113 and the second side plate 114 are both hinged to the middle frame 120, and the hinge centers are collinearly arranged to ensure the stability of the rotation of the face mask assembly 110 relative to the middle frame 120 and facilitate the rotation and opening or rotation and closing actions of the face mask assembly 110.

[0040] Further, the panel 112, the first side plate 113, the bottom plate 115, and the second side plate 114 are connected end to end and together enclose an air outlet 116. The position of the air outlet 116 corresponds to the position of the outlet 131. The lower air duct 130 is used to guide the air flow blown out by the cross-flow fan 140 to the air outlet 116. The air outlet 116 is used to blow the air flow into the room. The first air deflector 151 and the second air deflector 152 are rotatably installed in the air outlet 116 to guide the air flow, thereby realizing the function of adjusting the air direction.

[0041] In this embodiment, the length direction of the first air deflector 151 is the same as the length direction of the second air deflector 152, that is, the rotation axis of the first air deflector 151 is parallel to the rotation axis of the second air deflector 152, so as to facilitate adjusting the air outlet direction. And the area of the second air deflector 152 is smaller than the area of the first air deflector 151. The first air deflector 151 plays a main air guiding role, and the second air deflector 152 plays an auxiliary air guiding role. The first air deflector 151 and the second air deflector 152 complement each other to enhance the air guiding effect.

[0042] It should be noted that the mask assembly 110 is provided with a buckle 117, and the middle frame 120 is provided with a card hole 122. The buckle 117 is engaged with the card hole 122 to fix the relative positions of the mask assembly 110 and the middle frame 120 when the mask assembly 110 is in the closed state, prevent the mask assembly 110 from accidentally detaching from the middle frame 120, and ensure the stability of the air conditioner 100 during operation. Specifically, before maintaining and cleaning the components inside the mask assembly 110 and the air deflector, it is necessary to first release the engagement state between the buckle 117 and the card hole 122, then turn the entire mask assembly 110 upward to open it, and synchronously drive the air deflector to move upward to make way, so as to facilitate the maintenance and cleaning of the components inside the mask assembly 110 and the air deflector.

[0043] In the air conditioner 100 according to the embodiment of the present invention, the lower air duct 130 and the middle frame 120 are both installed on the base 160. The mask assembly 110 is hinged to the middle frame 120. The first air deflector 151 and the second air deflector 152 are rotatably installed on the mask assembly 110, and the second air deflector 152 is arranged inside the first air deflector 151. The second air deflector 152 is used to always maintain a gap with the middle frame 120 and the lower air duct 130 when the mask assembly 110 rotates and opens relative to the middle frame 120. Compared with the prior art, since the air conditioner 100 provided by the present invention adopts the first air deflector 151 and the second air deflector 152 rotatably installed on the mask assembly 110 and the mask assembly 110 hinged to the middle frame 120, it can realize the displacement of the air deflector without completely removing the air deflector, prevent the air deflector from interfering with other components during the displacement process, facilitate the maintenance and cleaning of the components inside the air deflector, and effectively shorten the maintenance or cleaning cycle.

[0044] Second Embodiment

[0045] Please refer to Figures 7 to 9 In the embodiment of the present utility model, an air conditioner 100 is provided. Compared with the first embodiment, the difference in this embodiment lies in the different cooperation structures of the mask assembly 110 and the second air deflector 152.

[0046] In this embodiment, the mask assembly 110 is extended with a positioning cantilever 118. The positioning cantilever 118 is arranged in the middle of the panel 112 and extends into the air outlet 116. The second air deflector 152 is provided with a mating convex block 153. The mating convex block 153 is rotationally engaged with the positioning cantilever 118. The mating convex block 153 can rotate relative to the positioning cantilever 118. The positioning cantilever 118 is used to limit the mating convex block 153, thereby limiting the second air deflector 152 and improving the stability of the second air deflector 152 when rotating to direct the air flow.

[0047] Furthermore, the middle frame 120 is provided with a relief notch 123. The positioning cantilever 118 is arranged in the relief notch 123. The relief notch 123 is used to avoid the positioning cantilever 118. Specifically, the positioning cantilever 118 is used to disengage from the relief notch 123 when the mask assembly 110 rotates and opens, so as to synchronously drive the second air deflector 152 to shift, facilitating the maintenance and cleaning of the components inside the air deflector; the positioning cantilever 118 is also used to extend into the relief notch 123 when the mask assembly 110 rotates and closes, so as to ensure that the mask assembly 110 and the second air deflector 152 can be reset in place, thereby ensuring the stability of the operation of the air conditioner 100.

[0048] The beneficial effects of the air conditioner 100 described in the embodiment of the present utility model are the same as those of the first embodiment, and will not be elaborated here.

[0049] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
