Description

Technical Field

[0001] The present invention relates to the field of air conditioners, and more particularly, to an indoor unit and an air conditioner. Background Art

[0002] With the development of air conditioning technology, the original single air deflector and its driving structure can no longer meet the requirements of current air conditioners. In the prior art, in order to achieve an ultra-wide air supply angle, a design of double motors driving double air deflectors is adopted. When the two air deflectors are closed, the large air deflector is used to hide the small air deflector inside to meet the aesthetic requirements.

[0003] In order to achieve the above functions, in the prior art, generally an independent installation cavity is provided on one side of the middle frame to install the air deflector driving component, and a through hole is provided on the side wall of the air outlet so that the driving shaft of the driving component extends out and is inserted into the rotating shaft of the air deflector to drive the air deflector to rotate.

[0004] However, when the indoor unit blows cold air, the air at the air outlet will flow into the installation cavity through the gap between the side wall of the through hole and the driving shaft. Inside the installation cavity, cold and hot air meet and form condensation. If the condensation cannot be dried in time, problems such as corrosion of metal parts will occur. Summary of the Invention

[0005] The objectives of the present invention include, for example, providing an indoor unit and an air conditioner that can improve the problem of condensation formation in the installation cavity.

[0006] Embodiments of the present invention can be implemented as follows:

[0007] In a first aspect, the present invention provides an indoor unit, including a base and a middle frame;

[0008] The middle frame is mounted on the base. The base and the middle frame are provided with an air duct, and the middle frame is provided with an air outlet communicating with the air duct;

[0009] A driving component installation cavity is provided on one side of the middle frame, and a through hole communicating with the air outlet is provided on the side wall of the installation cavity. The through hole is used for the transmission shaft of the driving component to extend out to be connected with the air deflector;

[0010] On the lower end of the air duct, and on one side close to the through hole, an outwardly convex air guiding rib is provided. The air guiding rib can deflect the air blown out from the air outlet to the upper region of the through hole.

[0011] In this embodiment, an outwardly convex air guiding rib is provided at the end on the lower side of the air duct and on the side close to the through hole. In this way, the air guiding rib can guide the air blown out from the air outlet to the upper area of the through hole, so that the air sent out from the air outlet does not pass through the through hole, and thus the liquid in the air sent out from the air outlet will not flow into the installation cavity through the gap, thereby improving or even solving the problem of condensation in the installation cavity.

[0012] In an alternative embodiment, the air guiding rib is located above the through hole; and / or,

[0013] The plane where the upper surface of the air guiding rib is located is above the through hole.

[0014] In this application, the air guiding rib is arranged above the through hole, so that the air corresponding to the air guiding rib at the air outlet will flow over the through hole. And the plane where the upper surface of the air guiding rib is located is above the through hole, so that the air sent out from the air outlet will be sent into the room along the plane where the upper surface of the air guiding rib is located, thereby preventing the air sent out from the air outlet from passing through the through hole.

[0015] In an alternative embodiment, the air guiding rib extends horizontally outwards; and / or,

[0016] The upper surface of the air guiding rib is inclined, and the inclination angle ranges from 2° to 5°.

[0017] In this application, the air guiding rib is arranged horizontally and extends outwards, which is convenient for air guiding and forming. The upper surface of the air guiding rib is inclined, and the inclination angle ranges from 2° to 5°, which can guide the air away from the through hole, so that it flows out from above the through hole.

[0018] In an alternative embodiment, the length of the air guiding rib ranges from 30 mm to 40 mm, the width of the air guiding rib ranges from 5 mm to 15 mm, and the thickness of the air guiding rib ranges from 2 mm to 5 mm.

[0019] Setting the air guiding rib with the above parameters will not affect the air supply angle of the air outlet too much and will not affect the closing of the small air damper.

[0020] In an alternative embodiment, a water storage tank is provided at the end on the lower side of the air duct and in the area below the air guiding rib, and the condensation on the back of the air guiding rib can flow into the water storage tank.

[0021] In this way, the condensation formed on the surface of the air guiding rib due to the temperature difference on both sides can be stored in the water storage tank and will not fall off, and since the water outlet tank is close to the air outlet, it is easier to dry.

[0022] In an alternative embodiment, the lower surface of the air guiding rib is inclined towards the water storage tank to enable the condensation to flow into the water storage tank.

[0023] The lower surface of the air guiding rib is inclined, so as to guide the condensed water, making it easier for the condensed water to flow into the water storage tank.

[0024] In an alternative embodiment, it is characterized in that the inclination angle of the lower surface of the air guiding rib ranges from 2° to 5°.

[0025] Setting the range to 2° - 5° will not increase the surface area too much, so that under the condition of relatively less condensed water generated, the diversion can still be realized.

[0026] In an alternative embodiment, the base includes a base body and a volute provided on the base body;

[0027] The middle frame includes a middle frame body and an upper folding plate. The air outlet is provided on the middle frame body. One end of the upper folding plate is connected to the lower side of the middle frame body where the air outlet is located, and the upper folding plate inclines inward to abut against the volute to form a wind duct shell;

[0028] The air guiding rib is provided on the side of the upper folding plate away from the volute, and the side of the air guiding rib close to the installation cavity is connected to the middle frame body.

[0029] This makes it more convenient for processing the air guiding rib and for installation.

[0030] In an alternative embodiment, the angle between the air guiding rib and the upper folding plate ranges from 130° to 160°.

[0031] Setting the angle to a range of 130° - 160° is convenient for better air guiding and will not cause eddy currents to affect the air volume.

[0032] In a second aspect, the present invention provides an air conditioner, including an outdoor unit and the indoor unit according to any one of the foregoing embodiments;

[0033] The indoor unit further includes a driving component and an air guiding door;

[0034] The driving component is installed in the installation cavity, and the transmission shaft of the driving component extends into the air outlet through the through hole;

[0035] The air guiding door is installed at the air outlet and is connected to the transmission shaft of the driving component, and the driving component can drive the air guiding door to rotate.

[0036] The air conditioner provided by the present application can, through the air guiding rib, improve or avoid the problem of condensed water formation in the installation cavity of the driving component. Description of the Drawings

[0049] Embodiment

[0050] Please refer to Figure 1 , this embodiment provides an air conditioner, which includes an indoor unit 100 and an outdoor unit. The outdoor unit and the indoor unit 100 are connected through pipes to adjust the indoor environment.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 , in this embodiment, the indoor unit 100 includes a base 110 and a middle frame 130. The middle frame 130 is installed on the base 110. The base 110 and the middle frame 130 are provided with an air duct 120. The middle frame 130 is provided with an air outlet 131 communicating with the air duct 120. On one side of the middle frame 130, there is an installation cavity 133 for a driving assembly 190, and a through hole 135 communicating with the air outlet 131 is provided on the side wall of the installation cavity 133. The through hole 135 is used for the transmission shaft of the driving assembly 190 to extend out to be connected to the air deflector 170. At the lower end of the air duct 120, and on one side close to the through hole 135, there is an outwardly protruding air guiding rib 137. The air guiding rib 137 can deflect the air blown out from the air outlet 131 to the upper area of the through hole 135.

[0052] In this embodiment, by providing an outwardly protruding air guiding rib 137 at the lower end of the air duct 120 and on one side close to the through hole 135, the air guiding rib 137 can deflect the air blown out from the air outlet 131 to the upper area of the through hole 135, so that the air sent out from the air outlet 131 does not pass through the through hole 135. In this way, the air sent out from the air outlet 131 will not flow into the installation cavity 133 through the gap, thereby improving or even solving the problem of condensation in the installation cavity 133.

[0053] Please refer to Figure 2 and Figure 4, in this embodiment, the air guiding rib 137 is located above the through hole 135. The air guiding rib 137 extends horizontally outwards, the upper surface of the air guiding rib 137 is inclined, and the value range of the inclination angle is 2° - 5°. The plane where the upper surface of the air guiding rib 137 is located is above the through hole 135.

[0054] In this embodiment, the air guiding rib 137 is arranged above the through hole 135, so that the air corresponding to the air outlet 131 and the air guiding rib 137 will flow over the through hole 135 from above. The air guiding rib 137 is horizontally arranged and extends outwards, which is convenient for air guiding and forming. The upper surface of the air guiding rib 137 is inclined, and the value range of the inclination angle is 2° - 5°, which can guide the air away from the through hole 135 and thus flow out from above the through hole 135. And the plane where the upper surface of the air guiding rib 137 is located is above the through hole 135, so that the air sent out by the air outlet 131 will be sent into the room along the plane where the upper surface of the air guiding rib 137 is located, so that the air sent out by the air outlet 131 will not pass through the through hole 135.

[0055] Please refer to Figure 2 and Figure 4 , in this embodiment, the value range of the length of the air guiding rib 137 is 30mm - 40mm, the value range of the width of the air guiding rib 137 is 5mm - 15mm, and the value range of the thickness of the air guiding rib 137 is 2mm - 5mm.

[0056] In this embodiment, the length of the air guiding rib 137 is 32.8mm, the width of the air guiding rib 137 is 9mm, and the thickness of the air guiding rib 137 is 3mm.

[0057] Setting the air guiding rib 137 to the above parameters will not affect the air supply angle of the air outlet 131 too much and will not affect the closing of the small air guiding door 170.

[0058] In this embodiment, the horizontal distance from the center of the through hole 135 to the end of the air outlet 131 is 20mm, which is greater than the width of the air guiding rib 137, so that the air guiding function can be achieved without affecting the normal closing of the air guiding door 170. The vertical distance from the center of the through hole 135 to the end of the air outlet 131 is 40mm, so that the air guiding plate is located above.

[0059] Please refer to Figure 2 and Figure 4 , in this embodiment, at the lower end of the air duct 120 and in the area below the air guiding rib 137, a water storage tank 139 is arranged, and the condensate on the back of the air guiding rib 137 can flow into the water storage tank 139.

[0060] In this way, the condensate formed on the surface of the air guiding rib 137 due to one side being cold and the other side being hot can be stored in the water storage tank 139 and will not fall off, and because the water outlet tank is close to the air outlet 131, it is easier to dry.

[0061] In this embodiment, the lower surface of the air guide rib 137 is inclined toward the water storage tank 139 so that condensation flows to the water storage tank 139 .

[0062] The lower surface of the air guide rib 137 is inclined so as to guide the condensation and make it easier for the condensation to flow into the water storage tank 139 .

[0063] In this embodiment, the inclination angle of the lower surface of the wind guiding rib 137 is in the range of 2°-5°.

[0064] The value range is set to 2°-5°, which will not increase the surface area too much, thereby achieving diversion with relatively little condensation.

[0065] Of course, in some other embodiments of the present application, the wind guide rib 137 may also be set to be tilted upward or tilted downward, and it is only necessary to ensure that the plane of the upper surface of the wind guide rib 137 is located above the penetration hole 135.

[0066] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the base 110 includes a base body 111 and a volute 113 disposed on the base body 111. The middle frame 130 includes a middle frame body 141 and an upper folding plate 143. The air outlet 131 is disposed on the middle frame body 141. One end of the upper folding plate 143 is connected to the middle frame body 141 at the lower side of the air outlet 131, and the upper folding plate 143 is inclined inwardly and abuts against the volute 113 to form an air duct 120 shell. The air guide rib 137 is disposed on a side of the upper folding plate 143 away from the volute 113, and the side of the air guide rib 137 close to the installation cavity 133 is connected to the middle frame body.

[0067] This can increase the strength of the air guiding ribs 137 and facilitate molding.

[0068] In this embodiment, the angle between the wind guiding rib 137 and the upper folding plate 143 ranges from 130° to 160°.

[0069] Setting the angle to 130°-160° facilitates better wind guidance without causing eddy currents that affect air volume.

[0070] Specifically, the angle between the wind guide rib 137 and the upper folding plate 143 is 144°. This will not form eddy currents and can facilitate splicing with the volute 113.

[0071] In this embodiment, the indoor unit 100 further includes a driving component 190 and a guiding air door 170. The driving component 190 is installed in the installation cavity 133, and the transmission shaft of the driving component 190 extends into the air outlet 131 through the through hole 135. The guiding air door 170 is installed at the air outlet 131 and is connected to the transmission shaft of the driving component 190. The driving component 190 can drive the guiding air door 170 to rotate.

[0072] This facilitates the installation of the driving component 190 and the installation of the guiding air door 170 on the transmission shaft very conveniently.

[0073] Please refer to Figure 2 、 Figure 3 and Figure 4 , in this embodiment, a plug hole is provided at the end of the rotating shaft of the guiding air door 170. After the transmission shaft of the driving component 190 extends into the air outlet 131 through the through hole 135, it is inserted into the plug hole, and then the transmission connection can be realized.

[0074] In this embodiment, the indoor unit 100 further includes a small guiding air door 170. The small guiding air door 170 is rotatably installed at the air outlet 131. Generally, the guiding air door 170 opens downward, and the small guiding air door 170 opens upward. When both the guiding air door 170 and the small guiding air door 170 are closed, the guiding air door 170 blocks the outside of the small guiding air door 170.

[0075] In this embodiment, a shaft sleeve is further provided in the through hole 135. The shaft sleeve is installed on the inner wall of the through hole 135, and the transmission shaft of the driving component 190 extends out through the shaft sleeve.

[0076] In this embodiment, by providing the shaft sleeve, the gap of the through hole 135 can be made smaller while ensuring the rotation of the transmission shaft.

[0077] In summary, the working principles and beneficial effects of the indoor unit 100 and the air conditioner provided in this embodiment include:

[0078] In this application, a protruding air guiding rib 137 is provided at the lower end of the air duct 120 and close to one side of the through hole 135. In this way, the air guiding rib 137 can guide the air blown out from the air outlet 131 to the upper area of the through hole 135, so that the air sent out from the air outlet 131 does not pass through the through hole 135. In this way, the air sent out from the air outlet 131 will not flow into the installation cavity 133 from the gap, thereby improving or even solving the problem of condensation in the installation cavity 133.

[0079] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
