Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, and particularly relates to a portable air conditioner. Background Technology

[0002] The sweltering summer heat cannot dampen people's enthusiasm for outdoor camping, leading to the development of portable air conditioners. Portable air conditioners are characterized by their small size, light weight, and low power supply voltage, but these also result in drawbacks such as low airflow and limited cooling capacity. Improving the cooling effect of portable air conditioners has become a key research focus.

[0058] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0060] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0061] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0062] In existing portable air conditioners, the air inlet design of the casing is unreasonable, resulting in a small air intake area and a single air intake surface, which limits the placement of the air conditioner; the evaporator area is small, resulting in a small heat exchange area and poor heat exchange effect.

[0063] This invention creatively provides a portable air conditioner, including a housing and an evaporator. The housing includes a left side panel, a front side panel, and a right side panel. The left side panel, the front side panel, and the right side panel are respectively formed with a first left air inlet, a first front air inlet, and a first right air inlet. The front side panel is also formed with a first air outlet. A first cavity is formed between the first left air inlet, the first front air inlet, the first right air inlet, and the first air outlet. The evaporator is disposed in the first cavity and includes a left heat exchange section, a front heat exchange section, and a right heat exchange section. The left heat exchange section, the front heat exchange section, and the right heat exchange section are respectively corresponding to the first left air inlet, the first front air inlet, and the first right air inlet.

[0064] Air can enter the first cavity through the first left air inlet, the first front air inlet and the first right air inlet respectively and exchange heat with the corresponding heat exchange section, and then be discharged through the first air outlet;

[0065] The air intake surface has been expanded to achieve three-sided air intake, making the air conditioner's placement more flexible and solving the problem of small air intake area and single air intake surface caused by unreasonable air intake design of the casing; the heat exchange area of ​​the evaporator has been increased, enhancing the heat exchange effect and solving the problem of small heat exchange area and poor heat exchange effect caused by unreasonable evaporator structural design.

[0066] like Figure 1a and Figure 2 As shown, this embodiment provides a portable air conditioner, including:

[0067] The housing 1 includes a left side plate 11, a front side plate 12, a right side plate 13, a rear side plate 14, and a top plate. The left side plate 11, front side plate 12, right side plate 13, and rear side plate 14 are sequentially arranged and connected. The top plate is connected to the left side plate 11, front side plate 12, right side plate 13, and rear side plate 14. The left side plate 11 forms a first left air inlet 111, the front side plate 12 forms a first front air inlet 121 and a first air outlet 122, and the right side plate 13 forms a first right air inlet 131. The first left air inlet 111, the first front air inlet 121, and the first right air outlet 131 are also connected. A first cavity is formed between the right air inlet 131 and the first air outlet 122; preferably, the horizontal center lines of the areas occupied by the first left air inlet 111, the first front air inlet 121, and the first right air inlet 131 are all on the same horizontal plane; the first air outlet 122 is located above the first front air inlet 121; furthermore, the height values ​​of the areas occupied by the first left air inlet 111, the first front air inlet 121, and the first right air inlet 131 are equal;

[0068] Evaporator 2 is disposed in the first cavity and includes a left heat exchange section 21, a front heat exchange section 22 and a right heat exchange section 23 connected in sequence. The left heat exchange section 21 is configured to correspond to the first left air inlet 111, the front heat exchange section 22 is configured to correspond to the first front air inlet 121, and the right heat exchange section 23 is configured to correspond to the first right air inlet 131.

[0069] Air can enter the first cavity through the first left air inlet 111, the first front air inlet 121 and the first right air inlet 131 respectively and exchange heat with the corresponding heat exchange section, and then be discharged through the first air outlet 122.

[0070] In summary, the different side panels of the casing 1 form corresponding air inlets, enabling air intake from different sides, expanding the air intake surface, achieving three-sided air intake, increasing the air intake area, facilitating airflow at the air inlets, and making the air conditioner's placement more flexible. This solves the problem of small air intake area and single air intake surface caused by the unreasonable air inlet design of the casing 1. The evaporator 2 includes three heat exchange sections, and the three heat exchange sections are arranged one-to-one with the three air inlets, increasing the heat exchange area of ​​the evaporator 2 and enhancing the heat exchange effect. This solves the problem of small heat exchange area and poor heat exchange effect caused by the unreasonable structural design of the evaporator 2.

[0071] Furthermore, the first cavity includes a first air inlet cavity and a first air outlet cavity arranged vertically and connected to each other, with the first air inlet cavity at the top and the first air outlet cavity at the bottom; the first air inlet cavity is connected to the first left air inlet 111, the first front air inlet 121 and the first right air inlet 131, and the first air inlet cavity is provided with an evaporator 2; the first air outlet cavity is connected to the first air outlet 122; the left side plate 11, the front side plate 12 and the right side plate 13 are all formed with perforated grilles, the perforated grille of the left side plate 11 forms the first left air inlet 111, the perforated grille of the front side plate 12 forms the first front air inlet 121, and the perforated grille of the right side plate 13 forms the first right air inlet 131;

[0072] like Figures 2 to 4d As shown, to address the issue of high flow resistance when air flows through the first air inlet cavity and the first air outlet cavity, this embodiment proposes that the portable air conditioner also includes a guide component 3 and a first fan 41. The guide component 3 is disposed in the first air inlet cavity and located on the air outlet side of the evaporator 2; the first fan 41 is disposed in the first air outlet cavity; under the action of the first fan 41, the guide component 3 can guide the air flowing through the evaporator 2 to the first fan 41; thereby reducing air flow resistance and improving the heat exchange efficiency of the evaporator 2.

[0073] Furthermore, the air guide 3 has an air inlet guide surface and an air outlet guide surface 34 that are arranged vertically and connected, with the air inlet guide surface at the bottom and the air outlet guide surface 34 at the top; the air inlet guide surface includes a left air inlet guide surface 31, a front air inlet guide surface 32 and a right air inlet guide surface 33 connected in sequence; the left air inlet guide surface 31 is arranged corresponding to the left heat exchange section 21, the front air inlet guide surface 32 is arranged corresponding to the front heat exchange section 22, and the right air inlet guide surface 33 is arranged corresponding to the right heat exchange section 23; the air outlet guide surface 34 is arranged close to the first fan 41;

[0074] The position of the first left air inlet 111 corresponds to the position of the left air inlet guide surface 31. The air entering through the first left air inlet 111 flows through the left heat exchange section 21 and is guided by the left air inlet guide surface 31 to the outlet air guide surface 34. The position of the first front air inlet 121 corresponds to the position of the front air guide surface 32. The air entering through the first front air inlet 121 flows through the front heat exchange section 22 and is guided by the front air guide surface 32 to the outlet air guide surface 34. The position of the first right air inlet 131 corresponds to the position of the right air inlet guide surface 33. The air entering through the first right air inlet 131 flows through the right heat exchange section 23 and is guided by the right air inlet guide surface 33 to the outlet air guide surface 34. The outlet air guide surface 34 can guide the air to the first fan 41.

[0075] Preferably, the left air inlet guide surface 31, the front air inlet guide surface 32, and the right air inlet guide surface 33 are all arc-shaped curved surfaces, and the widths of the left air inlet guide surface 31, the front air inlet guide surface 32, and the right air inlet guide surface 33 gradually decrease from bottom to top;

[0076] The air outlet guide surface 34 is a hemispherical curved surface, and the air outlet guide surface 34 is tangent to the left air inlet guide surface 31, the front air inlet guide surface 32 and the air inlet guide surface.

[0077] like Figures 2 to 4d As shown, in response to the problem of high noise during the operation of compressor 43, this embodiment proposes that the portable air conditioner also includes a bottom shell 42 and a compressor 43. The bottom shell 42 is located at the bottom of the housing 1. A guide 3 is provided on the bottom shell 42, and a compressor cavity is formed between the bottom shell 42 and the guide 3. The compressor 43 is installed inside the compressor cavity. The compressor cavity can serve as a soundproof room, achieving the effect of sound insulation and noise reduction.

[0078] To address the problem of compressor 43 malfunctioning due to the failure to dissipate high temperatures during operation, this embodiment proposes that the guide element 3 be made of a heat-conducting material. The guide element 3 can achieve heat exchange between the air in the first air inlet chamber and the air in the compressor chamber, thereby improving the heat dissipation of compressor 43, ensuring stable operation of compressor 43, and preventing compressor 43 from malfunctioning due to high temperatures in the compressor chamber.

[0079] Furthermore, such as Figures 2 to 4d As shown, the portable air conditioner also includes a partition 44 and an electrical box 84. The partition 44 is located on the side of the air guide 3 away from the evaporator 2 and has a through hole and a mounting hole. The through hole is used for the pipe of the compressor 43 to pass through, so that the compressor 43 is connected to the evaporator 2. The mounting hole is used to install the electrical box 84 on the partition 44, so that the electrical box 84 and the partition 44 are arranged side by side.

[0080] like Figure 5a and Figure 5bAs shown, to address the problem that the grille at the outlet of existing portable air conditioners cannot achieve the air sweeping function, this embodiment proposes that the portable air conditioner also includes a grille assembly 5. The grille assembly 5 includes a bracket 51 and multiple plate-shaped grilles 52. The bracket 51 is disposed at the first air outlet 122, and the multiple plate-shaped grilles 52 are rotatably disposed on the bracket 51. Specifically, there are two brackets 51, which are disposed vertically at the first air outlet 122, and the multiple plate-shaped grilles 52 are disposed between the two brackets 51. The plate-shaped grilles 52 extend in the vertical direction, and the rotation axis of the plate-shaped grilles 52 also extends in the vertical direction.

[0081] Multiple plate-shaped grilles 52 can open or close the first air outlet 122 without the need for other components; when the first air outlet 122 is closed, outdoor insects and dust can be prevented from entering the housing 1, which could cause malfunctions of electrical or mechanical components; controlling the synchronous rotation of multiple plate-shaped grilles 52 can realize the air-sweeping function, centralized air supply, and adjustable air supply range, solving the problems of existing portable air conditioners not being able to realize the air-sweeping function and the air supply range not being adjustable; specifically, the multiple plate-shaped grilles 52 can realize the left and right air-sweeping function.

[0082] Furthermore, such as Figure 10a , Figure 10b and Figure 10c As shown, the portable air conditioner also includes a transmission assembly 6 and a drive assembly 7. The transmission assembly 6 includes a first connecting rod 61, a second connecting rod 62, and a third connecting rod 63. The first connecting rod 61 forms multiple grille connecting portions 611 and an A connecting rod connecting portion 612, the second connecting rod 62 forms a B connecting rod connecting portion, and the third connecting rod 63 forms a C1 connecting rod connecting portion and a C2 sliding groove 631. The drive assembly 7 includes a first drive motor 71, the output shaft of which is drivenly connected to a first drive base 711. The first drive base 711 is provided with a first... An eccentric shaft 712 is offset from the axis of rotation of the first drive seat 711, and the first drive seat 711 can drive the first eccentric shaft 712 to perform eccentric motion around the axis of rotation of the first drive seat 711; specifically, multiple grille connecting parts 611 are arranged sequentially at intervals along the length direction of the first connecting rod 61, and the A connecting rod connecting part 612 is located at the end of the first connecting rod 61; the C2 slide groove 631 extends along the length direction of the third connecting rod 63; the first connecting rod 61 and the third connecting rod 63 extend in the horizontal direction, and the second connecting rod 62 extends in the vertical direction;

[0083] Multiple grid connecting parts 611 are hinged together with multiple grids in a one-to-one correspondence; A connecting part 612 is hinged together with B connecting part; second connecting part 62 is hinged together with C1 connecting part; C2 sliding groove 631 is slidably engaged with first eccentric shaft 712.

[0084] like Figure 8aAs shown, when the first drive motor 71 rotates, the first drive seat 711 drives the first eccentric shaft 712 to rotate, causing the first connecting rod 61, the second connecting rod 62 and the third connecting rod 63 to move, thereby enabling the multiple plate-shaped grilles 52 to achieve the sweeping function.

[0085] The mechanism consisting of plate-shaped grilles 52, first connecting rod 61, second connecting rod 62, third connecting rod 63, and first eccentric shaft 712 has 8 revolute joints and 2 prismatic joints. The degree of freedom of this mechanism is: F = (8-1)×3 - 8×2 - 2×2 = 1. Therefore, when the first eccentric shaft 712 has a definite movement, each member of the mechanism has a definite movement. Since there are multiple plate-shaped grilles 52, the movement of the first connecting rod 61 is restricted, allowing only translational movement, ensuring that the opening and closing angles of each plate-shaped grille 52 are the same. When the second drive motor 72 is fixed, the first drive motor 71 moves, and the movement range of the multiple plate-shaped grilles 52 is as follows: Figure 8b As shown.

[0086] To address the issue of unstable movement of multiple plate-shaped grids 52, this embodiment proposes that there be two first connecting rods 61, with the B connecting rod connection portion consisting of a B1 connecting rod connection portion and a B2 connecting rod connection portion; the multiple grid connection portions 611 of one first connecting rod 61 are hinged to one end of the multiple grids in a one-to-one correspondence, and the multiple grid connection portions 611 of the other first connecting rod 61 are hinged to the other end of the multiple grids in a one-to-one correspondence; the A connecting rod connection portion 612 of one first connecting rod 61 is hinged to the B1 connecting rod connection portion, and the A connecting rod connection portion 612 of the other first connecting rod 61 is hinged to the B2 connecting rod connection portion;

[0087] Thus, when the third link 63 drives the second link 62 to move, the two first links 61 can cause multiple plate-shaped grilles 52 to rotate, thereby realizing the sweeping function.

[0088] like Figure 6a , Figure 6b , Figure 7 and Figure 9 As shown, in view of the problem that the grille at the outlet of the existing portable air conditioner cannot close the air outlet, which makes it easy for mosquitoes or dust to enter the housing 1, this embodiment proposes that the drive assembly 7 includes a second drive motor 72, the output shaft of the second drive motor 72 is drivenly connected to the second drive seat 721, the second drive seat 721 is provided with a second eccentric shaft 722, the second eccentric shaft 722 is offset from the rotation axis of the second drive seat 721, and the second drive seat 721 can drive the second eccentric shaft 722 to perform eccentric movement around the rotation axis of the second drive seat 721;

[0089] The transmission assembly 6 also includes a fourth link 64, which is spaced apart from the third link 63 along the length of the second link 62. The fourth link 64 has a D1 groove 641 and a D2 groove 642. The D1 groove 641 is slidably engaged with the second link 62, and the D2 groove 642 is slidably engaged with the second eccentric shaft 722. Specifically, the fourth link 64 extends horizontally, and both the D1 groove 641 and the D2 groove 642 extend along the length of the fourth link 64.

[0090] When the air conditioner is turned off, the second drive motor 72 rotates, and the second drive seat 721 drives the second eccentric shaft 722 to rotate, causing the first connecting rod 61, the second connecting rod 62, the third connecting rod 63, and the fourth connecting rod 64 to move. This causes the multiple plate-shaped grilles 52 to close or open the first air outlet 122. The mechanism composed of the multiple plate-shaped grilles 52, the first connecting rod 61, the second connecting rod 62, the third connecting rod 63, the fourth connecting rod 64, the first eccentric shaft 712, and the second eccentric shaft 722 includes 11 revolute joints and 3 prismatic joints. The degree of freedom of this mechanism is: F = (11-1)×3 - 11×2 - 3×2 = 2. Therefore, for this mechanism to have definite motion, it must have two definite driving members. At this time, both the first eccentric shaft 712 and the second eccentric shaft 722 are driven by motors and have definite motion. Therefore, the entire mechanism has definite motion. After the first drive motor 71 and the second drive motor 72 cooperate, the first air outlet 122 can be completely closed.

[0091] Furthermore, such as Figure 10c As shown, the first connecting rod 61 forms a limiting part 613, which is used to restrict the multiple plate-shaped grilles 52 from continuing to rotate when the multiple plate-shaped grilles 52 close the first air outlet 122; specifically, multiple limiting parts 613 are provided, and the multiple limiting parts 613 are arranged one-to-one with the multiple plate-shaped grilles 52; the limiting part 613 is a groove structure.

[0092] In addition, such as Figure 1b As shown, the rear panel 14 has a second air inlet 141 and a second air outlet 142 arranged side by side. The housing has a second cavity on the side near the second air inlet 141 and the second air outlet 142. The second cavity is arranged side by side with the first cavity. The portable air conditioner also includes an air inlet frame 81, a condenser 82 and a second fan 83. The air inlet frame 81, the condenser 82 and the second fan 83 are all arranged in the second cavity. The air inlet frame 81 is arranged near the second air inlet 141 and the second fan 83 is arranged near the second air outlet 142. The condenser 82 is located between the air inlet frame 81 and the second fan 83.

[0093] Under the action of the second fan 83, air enters the second cavity through the second air inlet 141, and after being guided by the air inlet frame, it exchanges heat with the condenser 82, and is then discharged through the second fan and the second air outlet 142.

It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
