Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and more particularly, to an air conditioner. Background Art

[0002] With the development of technology and the improvement of people's living standards, air conditioners that can adjust temperature have been more and more widely used.

[0003] After research by the inventor, it is found that after the middle frame and the base of some existing indoor units of air conditioners are installed and matched, a cavity is formed between the bottom plate, the upper folding plate on the middle frame and the base. Since the cavity is close to the air outlet, when external hot air enters the cavity, condensed water is likely to form. Summary of the Invention

[0004] An object of the present invention is to provide an air conditioner that can effectively prevent external hot air from entering the cavity, thereby reducing the generation of condensed water.

[0005] Embodiments of the present invention are implemented as follows:

[0006] In a first aspect, the present invention provides an air conditioner, including:

[0007] A base including a lower edge plate;

[0008] A middle frame connected to the base, the middle frame including a bottom plate and an upper folding plate provided on the bottom plate, the bottom plate, the upper folding plate and the lower edge plate jointly defining a cavity extending along the length direction of the air conditioner;

[0009] Two first windshields respectively provided at both ends of the cavity to prevent air outside both ends of the cavity from entering the cavity.

[0010] With the above arrangement, two first windshields are respectively provided at both ends of the cavity to prevent air outside both ends of the cavity from entering the cavity. Therefore, when the air conditioner is cooling, external hot air can be effectively prevented from entering the cavity, thereby reducing the formation of condensed water in the cavity.

[0011] In an alternative embodiment, the upper folding plate is provided with a first mating hole, the lower edge plate is provided with a second mating hole corresponding to the first mating hole, and the air conditioner further includes a wind separating member, the wind separating member and the lower edge plate and the upper folding plate jointly defining an independent chamber separated from the cavity, and the first mating hole and the second mating hole are both communicated with the independent chamber.

[0012] With the above arrangement, an independent chamber separated from the cavity can be jointly defined by the wind separating member, the lower edge plate and the upper folding plate. Therefore, when external hot air enters the independent chamber from the first mating hole or the second mating hole, it will no longer enter the cavity, avoiding the situation of a large area of condensed water in the cavity.

[0013] In an alternative embodiment, the wind baffle includes a second wind baffle. Second wind baffles are provided on both sides of the first fitting hole and the second fitting hole. The second wind baffles located on both sides of the first fitting hole and the second fitting hole, together with the bottom plate, the upper folding plate and the lower edge plate, define an independent chamber.

[0014] With the above arrangement, the two second wind baffles partition the cavity. The first fitting hole and the second fitting hole located between the two second wind baffles are defined in the second independent chamber, so that after the external hot air enters the second independent chamber from the first fitting hole or the second fitting hole, it cannot enter the cavity anymore, thereby reducing the generation of condensed water.

[0015] In an alternative embodiment, the air conditioner further includes a third wind baffle. The third wind baffle is disposed in the cavity and fits against the inner wall of the cavity for partitioning the chambers on both sides of the third wind baffle.

[0016] With the above arrangement, under the action of the third wind baffle, the range of internal circulation of the hot air can be restricted, and large-area condensed water in the cavity can be avoided.

[0017] In an alternative embodiment, at least one of the first wind baffle, the second wind baffle and the third wind baffle is integrally formed with the middle frame.

[0018] With the above arrangement, the connection strength between the first wind baffle, the second wind baffle and the third wind baffle and the middle frame can be ensured.

[0019] In an alternative embodiment, the first wind baffle includes a first side wall, a second side wall and a third side wall connected in sequence. The first side wall fits against the bottom plate, the second side wall fits against the inner wall of the lower edge plate, and the third side wall fits against the inner wall of the upper folding plate.

[0020] With the above arrangement, the first side wall fits against the bottom plate, the second side wall fits against the inner wall of the lower edge plate, and the third side wall fits against the inner wall of the upper folding plate to ensure the sealing performance of the connection with the inner wall of the cavity.

[0021] In an alternative embodiment, a groove is formed at one end of the lower edge plate. The groove has a first groove wall and a second groove wall connected at an angle. The first groove wall faces the upper folding plate and abuts against the end of the upper folding plate away from the bottom plate.

[0022] With the above arrangement, the assembly stability between the base and the middle frame is ensured.

[0023] In an alternative embodiment, the lower edge plate is provided with a first fitting portion, and the upper folding plate is provided with a second fitting portion inserted into the first fitting portion. The first fitting portion is a jack, and the second fitting portion is a snap.

[0024] With the above settings, the base and the middle frame can be pre-assembled by inserting the buckle into the socket. After the insertion is completed, it is convenient for the user to install the threaded fasteners.

[0025] In an alternative embodiment, the base further includes a shielding pad. The shielding pad is disposed on a side of the lower edge plate away from the upper folding plate and covers the socket, and the buckle is located on a side of the shielding pad close to the lower edge plate.

[0026] With the above settings, it can effectively prevent external hot air from entering the cavity through the socket, thereby further preventing the generation of condensed water in the cavity.

[0027] In an alternative embodiment, at least one of the bottom plate and the upper folding plate is provided with a reinforcing rib.

[0028] With the above settings, the strength of the bottom plate or the upper folding plate is improved.

[0029] The beneficial effects of the embodiments of the present invention are as follows: An air conditioner provided by the embodiments of the present invention includes a base, a middle frame, and a first wind shield. The base includes a lower edge plate, the middle frame is connected to the base, the middle frame includes a bottom plate and an upper folding plate disposed on the bottom plate, and the bottom plate, the upper folding plate, and the lower edge plate jointly define a cavity extending along the length direction of the air conditioner. The number of the first wind shields is two, and the two first wind shields are respectively disposed at both ends of the cavity for preventing air outside both ends of the cavity from entering the cavity. Therefore, when the air conditioner is refrigerated, it can effectively prevent external hot air from entering the cavity, thereby reducing the formation of condensed water in the cavity.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0043] The following will introduce in detail the specific structure of the air conditioner provided by the embodiments of the present invention and the corresponding technical effects brought thereby with reference to the patent drawings.

[0044] Please refer to Figures 1 - 5 , an air conditioner provided by an embodiment of the present invention includes a base 10, a middle frame 20, and a first wind deflector 30.

[0045] The base 10 includes a lower edge plate 11. The middle frame 20 is connected to the base 10. The middle frame 20 includes a bottom plate 21 and an upper folding plate 22 provided on the bottom plate 21. The bottom plate 21, the upper folding plate 22, and the lower edge plate 11 jointly define a cavity 80 extending along the length direction of the air conditioner. That is to say, when the base 10 and the middle frame 20 are assembled and connected, a cavity 80 is formed between the bottom plate 21 and the upper folding plate 22 of the middle frame 20 and the lower edge plate 11 of the base 10, which extends along the length direction of the air conditioner.

[0046] It should be noted that the air conditioner refers to the indoor unit of a wall-mounted unit. After the base 10 and the middle frame 20 are assembled and connected, there is a cavity 80. There are openings at both ends of the cavity 80 in the length direction. Therefore, external hot air easily enters the inside of the cavity 80 from both ends of the cavity 80. When the air conditioner is in the cooling state, when the hot air contacts the relatively cold inner wall of the cavity 80, condensed water is likely to be formed.

[0047] It should be noted that the side wall of the bottom plate 21 close to the cavity 80 can be understood as the inner wall of the cavity 80, the side wall of the lower edge plate 11 close to the upper folding plate 22 can be understood as the inner wall of the cavity 80, and the side wall of the upper folding plate 22 close to the lower edge plate 11 can also be understood as the inner wall of the cavity 80.

[0048] In this embodiment, please refer to Figure 5 , the number of the first wind deflectors 30 is two. The two first wind deflectors 30 are respectively arranged at both ends of the cavity 80 to prevent the air outside both ends of the cavity 80 from entering the cavity 80. It can be understood that the two first wind deflectors 30 arranged at both ends of the cavity 80 can prevent the air at both ends of the cavity 80 from entering the cavity 80. Therefore, when the air conditioner is cooling, it can effectively prevent external hot air from entering the cavity 80, thereby reducing the formation of condensed water in the cavity 80.

[0049] Specifically, the first wind deflector 30 includes a first side wall 31, a second side wall 32, and a third side wall 33 that are connected in sequence. The first side wall 31 is attached to the bottom plate 21, the second side wall 32 is attached to the inner wall of the lower edge plate 11, and the third side wall 33 is attached to the inner wall of the upper folding plate 22 to ensure the sealing performance of the connection with the inner wall of the cavity 80.

[0050] The inner wall of the lower edge plate 11 can be understood as the side wall of the lower edge plate 11 close to the cavity 80, and the inner wall of the upper folding plate 22 can be understood as the side wall of the upper folding plate 22 close to the cavity 80.

[0051] In detail, in some embodiments, in order to reduce the stress concentration and burrs at the connection between the bottom plate 21 and the upper folding plate 22, the connection between the bottom plate 21 and the upper folding plate 22 has a chamfer. Therefore, the first wind deflector 30 further includes a fourth side wall 34. The two ends of the fourth side wall 34 are respectively connected to the first side wall 31 and the third side wall 33, and the fourth side wall 34 is used to fit with the chamfer at the connection between the bottom plate 21 and the upper folding plate 22.

[0052] In detail, in order to ensure the assembly stability between the base 10 and the middle frame 20, optionally, one end of the lower edge plate 11 is provided with a groove. The groove has a first groove wall 111 and a second groove wall 112 that are connected at an angle. The first groove wall 111 faces the upper folding plate 22 and abuts against the end of the upper folding plate 22 away from the base 10.

[0053] Optionally, the upper folding plate 22 is provided with a first fitting hole, the lower edge plate 11 is provided with a second fitting hole corresponding to the first fitting hole, and the air conditioner further includes a wind separation member. The wind separation member and the lower edge plate 11 and the upper folding plate 22 jointly define an independent chamber 90 separated from the cavity 80, and the first fitting hole and the second fitting hole are both communicated with the independent chamber 90.

[0054] In detail, at least one of the above-mentioned first fitting hole and the second fitting hole is a threaded hole. When the base 10 and the middle frame 20 are connected by a threaded fastener, the threaded fastener can pass through the first fitting hole and the second fitting hole to tightly connect the middle frame 20 and the base 10.

[0055] After the threaded fastener passes through, external hot air may enter the cavity 80 from the first fitting hole or the second fitting hole, which is likely to cause a large area of condensate in the cavity 80. However, in this embodiment, an independent chamber 90 separated from the cavity 80 can be jointly defined by the wind separation member and the lower edge plate 11 and the upper folding plate 22. Therefore, when external hot air enters the independent chamber 90 from the first fitting hole or the second fitting hole, it will no longer enter the cavity 80, avoiding the situation of a large area of condensate in the cavity 80.

[0056] Please refer to Figures 2 - 3, It should be noted that the number of the first mating holes and the second mating holes can be multiple. Similarly, in order to prevent a large amount of condensed water from appearing in the cavity 80, the number of the air separation members can also be multiple, and each air separation member corresponds to each first mating hole and each second mating hole one by one.

[0057] Optionally, the air separation member includes a second wind baffle 40. Second wind baffles 40 are arranged at both ends of the first mating hole and the second mating hole. The second wind baffles 40 located on both sides of the first mating hole and the second mating hole, together with the bottom plate 21, the upper folding plate 22 and the lower edge plate 11, define an independent chamber 90.

[0058] In other words, the two second wind baffles 40 partition the cavity 80, and the first mating hole and the second mating hole located between the two second wind baffles 40 are defined in the independent chamber 90, so that after the external hot air enters the independent chamber 90 from the first mating hole or the second mating hole, it cannot enter the cavity 80 anymore, thereby reducing the generation of condensed water.

[0059] Certainly, in some other alternative embodiments, the air separation member can also be an annular air separation structure. That is to say, both ends of the annular air separation member are respectively abutted against the upper folding plate 22 and the lower edge plate 11, so that a part of the inner wall of the upper folding plate 22, a part of the inner wall of the lower edge plate 11 and the annular peripheral wall of the air separation member jointly form an independent chamber 90, thereby defining the first mating hole and the second mating hole in the annular independent chamber 90.

[0060] For the convenience of installing the base 10 and the middle frame 20, the lower edge plate 11 is provided with a first mating part, and the upper folding plate 22 is provided with a second mating part inserted into the first mating part. The first mating part is a jack 12, and the second mating part is a buckle 23. It can be understood that when the base 10 and the middle frame 20 are installed, the pre-assembly of the base 10 and the middle frame 20 can be realized by inserting the buckle 23 into the jack 12. After the insertion is completed, a threaded fastener is passed through the first mating hole and the second mating hole to tightly connect the middle frame 20 and the base 10.

[0061] Certainly, in order to ensure the stability of the pre-assembly of the base 10 and the middle frame 20, the number of buckles 23 on the upper folding plate 22 is multiple and arranged at intervals along the length direction, and the number of jacks 12 opened on the lower edge plate 11 is also multiple and the multiple jacks 12 are arranged at intervals along the length direction.

[0062] Certainly, in some other embodiments, the first mating part can also be a buckle 23, and the second mating part can also be a jack 12.

[0063] Please refer to Figures 2 - 5, Optionally, to prevent external hot air from entering the cavity 80 through the jack 12 of the lower edge plate 11, in this embodiment, the base 10 further includes a shielding pad 70. The shielding pad 70 is disposed on the side of the lower edge plate 11 away from the upper folding plate 22 and covers the jack 12. The socket is located on the side of the shielding pad 70 close to the lower edge plate 11. That is to say, through the setting of the shielding pad 70, it can effectively prevent external hot air from entering the cavity 80 through the jack 12, thereby further preventing the generation of condensed water in the cavity 80.

[0064] Specifically, the above-mentioned shielding pad 70 can be a shielding foam. Of course, in some other alternative embodiments, the shielding pad 70 can also be made of other materials.

[0065] , Optionally, the air conditioner further includes a third wind deflector 50. The third wind deflector 50 is disposed in the cavity 80 and fits with the inner wall of the cavity 80, and is used to separate the cavities on both sides of the third wind deflector 50. That is to say, in the cavity 80, the cavities on both sides of the third wind deflector 50 cannot communicate. When there is a problem with the airtightness in the cavity 80, that is, when part of the hot air enters the cavity 80, under the action of the third wind deflector 50, it can limit the range of the internal circulation of the hot air and can prevent the large-area generation of condensed water in the cavity 80.

[0066] At least one of the first wind deflector 30, the second wind deflector 40 and the third wind deflector 50 is integrally formed with the middle frame 20. It can be understood that the integral formation can ensure the connection strength between the first wind deflector 30 or the second wind deflector 40 or the third wind deflector 50 and the middle frame 20.

[0067] In this embodiment, to increase the connection strength between the first wind deflector 30, the second wind deflector 40 and the third wind deflector 50 and the middle frame 20, the first wind deflector 30, the second wind deflector 40 and the third wind deflector 50 are integrally formed with the middle frame 20. That is to say, the bottom plate 21, the upper folding plate 22, the first wind deflector 30, the second wind deflector 40 and the third wind deflector 50 are integrally formed.

[0068] In some other embodiments, the first wind deflector 30, the second wind deflector 40 and the third wind deflector 50 can also be integrally formed with the side of the lower edge plate 11 close to the upper folding plate 22. Of course, in some other alternative embodiments, the first wind deflector 30 can also be detachably connected to the middle frame 20, the second wind deflector 40 can also be detachably connected to the middle frame 20, and the third wind deflector 50 can also be detachably connected to the middle frame 20.

[0069] It should be noted that the upper folding plate 22 of the middle frame 20 is connected to the bottom plate 21 at an angle. That is, the cavity 80 formed between the upper folding plate 22, the bottom plate 21 and the lower edge plate 11 is generally a triangular prism-shaped chamber of the middle frame 20. Therefore, in order to ensure the close fit between the first wind deflector 30, the second wind deflector 40 and the third wind deflector 50 and the inner wall of the cavity 80, the first wind deflector 30, the second wind deflector 40 and the third wind deflector 50 are all generally in the shape of triangular plates.

[0070] Optionally, in order to ensure the strength of the bottom plate 21 and the upper folding plate 22, at least one of the bottom plate 21 and the upper folding plate 22 is provided with a reinforcing rib 60. In this embodiment, both the bottom plate 21 and the upper folding plate 22 are provided with reinforcing ribs 60.

[0071] In summary, an air conditioner provided by an embodiment of the present invention includes a base 10, a middle frame 20 and a first wind deflector 30. The base 10 includes a lower edge plate 11. The middle frame 20 is connected to the base 10. The middle frame 20 includes a bottom plate 21 and an upper folding plate 22 provided on the bottom plate 21. The bottom plate 21, the upper folding plate 22 and the lower edge plate 11 jointly define a cavity 80 extending along the length direction of the air conditioner. The number of the first wind deflectors 30 is two. The two first wind deflectors 30 are respectively arranged at both ends of the cavity 80 and are used to prevent the air outside both ends of the cavity 80 from entering the cavity 80. Therefore, when the air conditioner is refrigerating, it can effectively prevent the external hot air from entering the cavity 80, thereby reducing the formation of condensed water in the cavity 80.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
