[0052] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0053] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0054] Hereinafter, with reference to the accompanying drawings, an integrated air conditioner 100 according to an embodiment of the present invention will be described.

[0055] like Figures 1-8 As shown, the integrated air conditioner 100 may include: a housing assembly 1, an air duct assembly 2, a first fan assembly, a second fan assembly, and an electrical control assembly 5.

[0056] like Figures 1-3As shown, the shell assembly 1 has a first air inlet 111, a first air outlet 112, a second air inlet 121 and a second air outlet 122, and the air duct assembly 2 is arranged in the shell assembly 1, so that the shell assembly 1 has a first air duct 21 and a second air duct 22, the first air duct 21 communicates the first air inlet 111 and the first air outlet 112, and the second air duct 22 communicates the second air inlet 121 and the second air outlet 122. The airflow outside the shell assembly 1 can enter the first air duct 21 through the first air inlet 111, and the airflow flowing through the first air duct 21 can be discharged to the outside of the shell assembly 1 through the first air outlet 112. The airflow outside the shell assembly 1 can also enter the second air duct 22 through the second air inlet 121, and the airflow flowing through the second air duct 22 can be discharged to the outside of the shell assembly 1 through the second air outlet 122.

[0057] It can be understood that the first air duct 21 and the second air duct 22 are independent of each other, and the airflows are not communicated with each other, but the relative positions of the first air duct 21 and the second air duct 22 are not limited, for example, the second air duct 22 can be completely located outside the first air duct 21, thereby facilitating processing, and for another example, the second air duct 22 can also penetrate the first air duct 21, as long as the airflow in the second air duct 22 does not enter the first air duct 21, and the airflow in the first air duct 21 does not enter the second air duct 22, and for another example, the first air duct 21 can also penetrate the second air duct 22, as long as the airflow in the first air duct 21 does not enter the second air duct 22, and the airflow in the second air duct 22 does not enter the first air duct 21.

[0058] In combination Figures 5-8 , the first fan assembly includes a first fan wheel 31 and a first motor 32, the first fan wheel 31 is arranged in the first air duct 21, and the first motor 32 drives the first fan wheel 31 to rotate, the second fan assembly includes a second fan wheel 41 and a second motor 42, the second fan wheel 41 is arranged in the second air duct 22, and the second motor 42 drives the second fan wheel 41 to rotate, and the electric control assembly 5 is connected with the first motor 32 and the second motor 42 respectively. When the electric control assembly 5 controls the first motor 32 to work, the first fan wheel 31 can work, so that the first air duct 21 flows the airflow along the direction from the first air inlet 111 to the first air outlet 112, and when the electric control assembly 5 controls the second motor 42 to work, the second fan wheel 41 can work, so that the second air duct 22 flows the airflow along the direction from the second air inlet 121 to the second air outlet 122.

[0059] In combination Figures 7-8For the integrated air conditioner 100, for example, there are also the first heat exchanger 6 arranged in the first air duct 21, the second heat exchanger 7 arranged in the second air duct 22, and the compressor 8 and the throttling element arranged in the refrigerant circulation flow path of the first heat exchanger 6 and the second heat exchanger 7, etc. The compressor 8 is also connected to the electric control assembly 5. When the electric control assembly 5 controls the compressor 8 to work, one of the first heat exchanger 6 and the second heat exchanger 7 is an evaporator, and the other is a condenser.

[0060] When the integrated air conditioner 100 works, the electric control assembly 5 can control the compressor 8, the first motor 32, and the second motor 42 to work respectively. The first motor 32 drives the first fan wheel 31 to rotate, so that the first air duct 21 circulates air flow along the direction from the first air inlet 111 to the first air outlet 112. The air flow exchanges heat with the first heat exchanger 6 when passing through the first air duct 21. Meanwhile, the second motor 42 drives the second fan wheel 41 to rotate, so that the second air duct 22 circulates air flow along the direction from the second air inlet 121 to the second air outlet 122. The air flow exchanges heat with the second heat exchanger 7 when passing through the second air duct 22.

[0061] The integrated air conditioner 100 can be used as a window air conditioner, a mobile air conditioner, a desktop air conditioner, etc. For example, when the integrated air conditioner 100 is used as a window air conditioner, the first air inlet 111 and the first air outlet 112 can be an indoor air inlet and an indoor air outlet arranged in the room, and the second air inlet 121 and the second air outlet 122 can be an outdoor air inlet and an outdoor air outlet arranged in the outdoor. When the window air conditioner performs a cooling mode, the first heat exchanger 6 is an evaporator, and the second heat exchanger 7 is a condenser. Cold air is sent out from the first air outlet 112, and hot air is sent out from the second air outlet 122. When the window air conditioner performs a heating mode, the first heat exchanger 6 is a condenser, and the second heat exchanger 7 is an evaporator. Hot air is sent out from the first air outlet 112, and cold air is sent out from the second air outlet 122. For simplicity of description, specific embodiments of the integrated air conditioner 100 used as a mobile air conditioner and a desktop air conditioner are not described here, and can be inferred based on the above principles.

[0062] As Figures 1-3As shown, the shell assembly 1 also has a third air inlet 13, and the air duct assembly 2 also makes the shell assembly 1 have a third air duct 23, which is in communication with the third air inlet 13, and the air duct assembly 2 has a third air outlet 24 which is in communication with the second air duct 22 and the third air duct 23. That is, the shell assembly 1 has the third air inlet 13, and the air duct assembly 2 has the third air outlet 24, the third air duct 23 is in communication with the shell assembly 1 through the third air outlet 24, and the third air duct 23 is in communication with the second air duct 22 through the third air outlet 24, so that when the pressure in the second air duct 22 is less than the pressure outside the shell assembly 1 at the third air inlet 13, the air outside the shell assembly 1 can be sucked into the third air duct 23 through the third air inlet 13, and then discharged to the second air duct 22 through the third air outlet 24, and then out of the second air outlet 122.

[0063] It can be understood that the third air duct 23 and the first air duct 21 are independent of each other and the airflow is not communicated, and the third air duct 23 and the second air duct 22 are also independent of each other except at the third air outlet 24, that is, the airflow of the third air duct 23 can enter the second air duct 22 through the third air outlet 24. However, the relative position of the third air duct 23 and the first air duct 21 is not limited, for example, the third air duct 23 can be located outside the first air duct 21, the third air duct 23 can also penetrate the first air duct 21, and the like, as long as the above requirements are met. Similarly, the relative position of the third air duct 23 and the second air duct 22 is not limited, for example, the third air duct 23 can be located outside the second air duct 22, the third air duct 23 can also penetrate the second air duct 22, and the like, as long as the above requirements are met. Herein, no further description is made.

[0064] Among them, at least one of the first motor 32, the second motor 42 and the electric control assembly 5 is arranged in the third air duct 23. That is, each of the first motor 32, the second motor 42 and the electric control assembly 5 can be arranged in the third air duct 23, two of the first motor 32, the second motor 42 and the electric control assembly 5 can be arranged in the third air duct 23, or one of the first motor 32, the second motor 42 and the electric control assembly 5 can be arranged in the third air duct 23. In this way, the airflow flowing through the third air duct 23 can dissipate heat from the heat source arranged in the third air duct 23, and the cooled airflow can be discharged from the second air outlet 122 in time with the airflow of the second air duct 22, thereby ensuring the cooling effect and improving the operation stability of the integrated air conditioner 100.

[0065] Therefore, by skillfully designing the airflow path, without adding other ventilation equipment, the third air duct 23 can be ventilated by using the negative pressure of the second air duct 22 itself, thereby achieving the cooling effect of at least one of the first motor 32, the second motor 42 and the electric control assembly 5, thereby reducing the cost of cooling.

[0066] With the economic development, the demand of window air conditioner gradually expands in the migratory population, and it is favored by more and more consumers because of its convenient installation and easy disassembly and carrying. The vertical window machine has become a mainstream direction, which realizes low noise, large wind volume and large cooling capacity design by double through-flow wind wheel air duct. Because it is an integrated small model, the internal space is very compact, and the heat dissipation of the internal frequency converter and the heat generating parts such as motor needs to be improved.

[0067] To solve at least one of the above problems, complex external auxiliary equipment is used in the related art, such as fans, heat conduction fins, heat pipes, refrigerant pipelines and main board substrates, but there are the following problems: (1) when independent controller cooling auxiliary equipment is used, separate cost investment is needed, and the production materials increase, the process increases and the production efficiency of the whole machine decreases, which increases the fixed cost of the whole machine; (2) when independent controller cooling auxiliary equipment is used, the reliability of the whole machine is affected by the increase of the equipment, which reduces the reliability of the whole machine; (3) when independent controller cooling auxiliary equipment is used, the complexity of the whole machine system is increased, which reduces the stability of the whole machine; (4) when independent controller cooling auxiliary equipment is used, a large amount of space is required in the design and layout of the whole machine, which is difficult to use in compact and portable whole machine under the development demand of small size; (5) when independent fan, refrigerant cooling and other cooling technology are used, complex control logic is needed to optimize control, which greatly increases the complexity of the control system; (6) the heat dissipation of the controller main board and the heat source in the control box, and the heat dissipation of the motor, respectively use different external auxiliary equipment, and a single external auxiliary equipment cannot simultaneously cool the above two, which results in higher cost, lower production efficiency, larger space occupation, lower stability, lower reliability and more complex control.

[0068] According to the integrated air conditioner 100 of the embodiment of the present application, the third air duct 23 is arranged in the shell assembly 1, the third air duct 23 is formed by the air outlet of the second air outlet 122 to form negative pressure, so that the air flow outside the shell assembly 1 can be continuously introduced into the third air duct 23 under the action of the negative pressure, and the air flow flowing into the third air duct 23 can cool the heat source arranged in the third air duct 23, such as the first motor 32, the second motor 42 and the electric control assembly 5, and then the air flow is sent out from the second air outlet 122 to discharge heat to the outside of the shell assembly 1, so as to realize the circulation of the air flow in the third air duct 23 to take away the heat to be discharged, thereby achieving reliable and effective cooling effect.

[0069] It can be seen that the third air duct 23 is used as a heat dissipation air path, and the power source is the power source possessed by the integrated air conditioner 100 during normal operation, i.e., the second fan assembly, so that the operation of the heat dissipation air path does not require the introduction of a new power source, which does not involve the material cost of auxiliary equipment and the subsequent energy input for the operation of the electrically controlled heat dissipation air path system, thereby reducing the cost, improving the production efficiency, and maintaining the compact structure, higher stability, higher reliability, and no increase in control difficulty. More specific analysis is as follows.

[0070] First, by setting the heat dissipation air path without introducing a new power source, the independent controller cooling auxiliary equipment is replaced. Since the controller production logistics is all necessary basic materials, the cost is reduced in terms of materials, the production process is reduced, the production efficiency of the whole machine is improved, and the inherent cost of the whole machine is greatly reduced. Therefore, the problem of the independent controller cooling auxiliary equipment, the separate cost input, the increase of production materials, the increase of production process, the reduction of the production efficiency of the whole machine, and the increase of the fixed cost of the whole machine is solved.

[0071] Second, by setting the heat dissipation air path without introducing a new power source, the independent controller cooling auxiliary equipment is replaced. Since there is no new device affecting the reliability, the reliability of the whole machine is higher. Therefore, the problem of the independent controller cooling auxiliary equipment, the increase of the affecting factors of the reliability of the whole machine with the new device, and the reduction of the reliability of the whole machine is solved.

[0072] Third, by setting the heat dissipation air path without introducing a new power source, the independent controller cooling auxiliary equipment is replaced. Since only the basic necessary structure of the whole machine is used, the structure is improved by improving the detail characteristics and layout design, and finally a simple ventilation and heat dissipation air path is realized, so that the system complexity is low, the stability is good, and the reliability is high. Therefore, the problem of the independent controller cooling auxiliary equipment, the increase of the complexity of the whole machine system, and the reduction of the stability and reliability of the whole machine is solved.

[0073] Fourth, by setting the heat dissipation air path without introducing a new power source, the independent controller cooling auxiliary equipment is replaced. Without the need for additional space for structure design, the air circulation and heat exchange inside the air path can still be realized to take away the required heat dissipation in the case of compact space of the integrated window machine. Therefore, the problem of the independent controller cooling auxiliary equipment, the increase of the space requirement in the design and layout of the whole machine, and the difficulty of using the compact machine and portable and light whole machine in the development demand of miniaturization of the whole machine, such as the compact space of the integrated window machine, is solved.

[0074] Fifth, by setting the heat dissipation air path without introducing a new power source, replacing the independent controller heat dissipation auxiliary equipment, thereby without adding complex control logic for optimization control, only need to be simple with the whole machine itself automatic opening and running, to achieve the whole machine operation can meet the demand of heat dissipation. Therefore, the problem of complex control logic is solved when the independent controller heat dissipation auxiliary equipment is used, which greatly increases the complexity of the control system.

[0075] Sixth, when the first motor 32, the second motor 42 and the electric control assembly 5 are arranged in the third air duct 23, a heat dissipation air path is utilized, and the motor heat source and the controller heat source are cooled at the same time, thereby meeting the demand of heat dissipation for both. Therefore, the problem of heat dissipation for only the controller mainboard and the internal heat source of the control box or only the heat dissipation for the huge motor heat source is solved, the problem of not being able to simultaneously heat dissipate for both is solved, and the problems of higher cost, lower production efficiency, larger space occupation, lower stability, lower reliability and more complex control caused by simultaneously arranging multiple heat dissipation auxiliary equipment are solved.

[0076] In some embodiments of the present application, as shown in Figures 1-3 The edge of the first air inlet 111 extends to a first extension area, the first extension area is staggered with the first air duct 21, and the third air inlet 13 is arranged in the first extension area. That is, the third air inlet 13 is arranged at the edge of the first air inlet 111, thereby improving the influence of the third air inlet 13 on the overall appearance effect of the shell assembly 1, and improving the influence of the third air inlet 13 on the structural reliability of the shell assembly 1.

[0077] For example, in some specific examples, as shown in Figures 1-3 The shell assembly 1 includes a first grid area 113 and a second grid area 123 arranged at intervals, the first air inlet 111 is arranged in the first grid area 113, the second air inlet 121 is arranged in the second grid area 123, and the third air inlet 13 is arranged in the first grid area 113. Therefore, the first air inlet 111 and the third air inlet 13 can be constructed by using the same first grid area 113, that is, the part of the grid holes on the first grid area 113 corresponding to the first air duct 21 is used as the first air inlet 111, and the part of the grid holes on the first grid area 113 corresponding to the third air duct 23 is used as the third air inlet 13, thereby not needing to separately process the third air inlet 13 on the shell assembly 1, and not needing to separately arrange the air inlet grid for processing the third air inlet 13. The air inlet grid corresponding to the original first air inlet 111 is enlarged, thereby simplifying the structure design, reducing the cost, and improving the structural reliability of the shell assembly 1.

[0078] In some embodiments of the present application, as shown inFigures 12-13 As shown, the edge of the second air inlet 121 extends to a second extension area, the second extension area is staggered with the second air duct 22, and the third air inlet 13 is arranged in the second extension area. That is, the third air inlet 13 is arranged at the edge of the second air inlet 121, so as to improve the influence of the third air inlet 13 on the overall appearance effect of the shell assembly 1, and improve the influence of the third air inlet 13 on the structural reliability of the shell assembly 1.

[0079] For example, in some specific examples, as shown in Figures 12-13 As shown, the shell assembly 1 comprises a first grid area 113 and a second grid area 123 arranged at intervals, the first air inlet 111 is arranged in the first grid area 113, the second air inlet 121 is arranged in the second grid area 123, and the third air inlet 13 is arranged in the second grid area 123. Therefore, the second air inlet 121 and the third air inlet 13 can be constructed by using the same second grid area 123, for example, the part of the grid holes in the second grid area 123 corresponding to the second air duct 22 is used as the second air inlet 121, and the part of the grid holes in the second grid area 123 corresponding to the third air duct 23 is used as the third air inlet 13, so that the third air inlet 13 does not need to be separately processed on the shell assembly 1, and the air inlet grid does not need to be separately arranged for processing the third air inlet 13. The air inlet grid corresponding to the original second air inlet 121 can be enlarged, so as to simplify the structural design, reduce the cost, and improve the structural reliability of the shell assembly 1.

[0080] In some embodiments of the present application, as shown in Figures 14-15 As shown, the edge of the first air inlet 111 extends to a first extension area, the first extension area is staggered with the first air duct 21, the edge of the second air inlet 121 extends to a second extension area, the second extension area is staggered with the second air duct 22, and the third air inlet 13 is arranged in the first extension area and the second extension area. That is, the third air inlet 13 is arranged at the edge of the first air inlet 111 and the edge of the second air inlet 121, respectively, so as to improve the ventilation volume of the third air duct 23, improve the influence of the third air inlet 13 on the overall appearance effect of the shell assembly 1, and improve the influence of the third air inlet 13 on the structural reliability of the shell assembly 1.

[0081] For example, in some specific examples, as shown in Figures 14-15As shown, the shell assembly 1 comprises a first grid area 113 and a second grid area 123 which are arranged apart, the first air inlet 111 is arranged at the first grid area 113, the second air inlet 121 is arranged at the second grid area 123, and the third air inlet 13 is arranged at the first grid area 113 and the second grid area 123. Thus, the first air inlet 111 and a part of the third air inlet 13 can be constructed by using the same first grid area 113, and the second air inlet 121 and another part of the third air inlet 13 can be constructed by using the same second grid area 123, so that the third air inlet 13 does not need to be separately processed on the shell assembly 1, and the air inlet grid for processing the third air inlet 13 does not need to be separately arranged, and the air inlet grid corresponding to the original first air inlet 111 and the air inlet grid corresponding to the original second air inlet 121 can be enlarged, so that the structure design can be simplified, the cost can be reduced, the structure reliability of the shell assembly 1 can be improved, and the ventilation capacity of the third air duct 23 can be improved.

[0082] Of course, the present application is not limited to this, and the first air inlet 111, the second air inlet 121 and the third air inlet 13 can not be formed by the grid holes, for example, in other embodiments of the present application, circular holes or the like can be directly formed on the shell assembly 1 as the first air inlet 111, the second air inlet 121 and the third air inlet 13.

[0083] It should be noted that the specific structure of the shell assembly 1 according to the embodiments of the present application is not limited, for example, in some embodiments of the present application, as shown in Figures 1-3 As shown, the shell assembly 1 can comprise a front shell 11 and a rear shell 12, the front shell 11 is arranged at the front side of the rear shell 12, the first air inlet 111 and the first air outlet 112 are arranged on the front shell 11, the second air inlet 121 and the second air outlet 122 are arranged on the rear shell 12, and the third air inlet 13 is arranged on at least one of the front shell 11 and the rear shell 12. Thus, the processing and design are facilitated, and when the integrated air conditioner 100 is a window air conditioner, the rear shell 12 can be arranged outdoors, and the front shell 11 can be arranged indoors, so that the first air inlet 111 and the first air outlet 112 can be located indoors as indoor air inlets and indoor air outlets, and the second air inlet 121 and the second air outlet 122 can be located outdoors as outdoor air inlets and outdoor air outlets, thereby meeting the use requirements.

[0084] And, the air current absorbing heat through the third air duct 23 can be sent out to the outdoor through the second air outlet 122, so as to avoid the adverse effect on the indoor temperature adjustment. In addition, it can be understood that if the third air inlet 13 is arranged on the front shell 11, the indoor air can be used for heat dissipation, and if the third air inlet 13 is arranged on the outdoor, the outdoor air can be used for heat dissipation. In addition, when the third air inlet 13 is arranged on the front shell 11, the arrangement position of the third air inlet 13 is not limited, for example, it can be arranged at the edge of the first air inlet 111, or it can be arranged separately from the first air inlet 111 and the first air outlet 112, and when the third air inlet 13 is arranged on the rear shell 12, the arrangement position of the third air inlet 13 is also not limited, for example, it can be arranged at the edge of the second air inlet 121, or it can be arranged separately from the second air inlet 121 and the second air outlet 122.

[0085] In addition, it is worth mentioning that the shapes of the front shell 11 and the rear shell 12 are not limited, for example, they can be flat plate shapes or cover body shapes, etc., for example, when they are cover body shapes, they can include panel parts and side plate parts on both sides of the panel parts, and the air inlets can be arranged on at least one of the panel parts and the side plate parts according to the needs, which are not limited and described here. When the shell assembly 1 includes the above-mentioned first grille area 113, the first grille area 113 can be a grille piece mounted on the front shell 11, or it can be a plurality of grille bars integrally formed on the front shell 11, and when the shell assembly 1 includes the above-mentioned second grille area 123, the second grille area 123 can be a grille piece mounted on the rear shell 12, or it can be a plurality of grille bars integrally formed on the rear shell 12.

[0086] In some embodiments of the present application, as shown in Figure 3 and Figure 7 The first air duct 21 is located outside the second air duct 22, and the third air duct 23 is located outside the first air duct 21 and outside the second air duct 22. That is, the first air duct 21 is located outside the second air duct 22, the second air duct 22 is located outside the first air duct 21, the third air duct 23 is located outside the second air duct 22, and the third air duct 23 is also located outside the first air duct 21. Thus, it is convenient to process, simplify the structure, and improve the stability of each air current path.

[0087] Optionally, as shown in Figure 3 and Figure 7As shown, the first wind wheel 31 and the second wind wheel 41 are both cross-flow wind wheels and are arranged in parallel, that is, the first wind wheel 31 and the second wind wheel 41 are both cross-flow wind wheels, and the rotation axis of the first wind wheel 31 and the rotation axis of the second wind wheel 41 are parallel. In this way, the space can be saved to improve the compactness of the structure, wherein the first motor 32 and the second motor 42 are located on the same side of the first wind wheel 31 and the second wind wheel 41 in the axial direction, for example, the rotation axis of the first wind wheel 31 and the rotation axis of the second wind wheel 41 both extend in the up-down direction, the first motor 32 is located on the upper side of the first wind wheel 31, and the second motor 42 is also located on the upper side of the second wind wheel 41, so that the first motor 32 and the second motor 42 are located on the same side of the first wind wheel 31 and the second wind wheel 41 in the axial direction, thereby facilitating wiring and maintenance, and facilitating simultaneous heat dissipation of the first motor 32 and the second motor 42, and simplifying the structure.

[0088] Further, as shown, Figure 3 The third air duct 23 can include at least one of a first section 231 and a second section 232, the second section 232 is located on one side of the first wind wheel 31 and the second wind wheel 41 in the circumferential direction and accommodates the electric control assembly 5, and the first section 231 is located on one side of the first wind wheel 31 and the second wind wheel 41 in the axial direction and accommodates the first motor 32 and the second motor 42. In this way, the structure is simpler, easier to process, and has higher reliability.

[0089] Of course, the present application is not limited thereto, and in other embodiments of the present application, the types of the first wind wheel 31 and the second wind wheel 41 are not limited, for example, the first wind wheel 31 can also be an axial flow wind wheel, or a centrifugal wind wheel, or an inclined flow wind wheel, etc., and for example, the second wind wheel 41 can also be an axial flow wind wheel, or a centrifugal wind wheel, or an inclined flow wind wheel, etc., which will not be repeated here.

[0090] In some embodiments of the present application, as Figure 3As shown, the third air duct 23 includes an upper section 2310 and a lower section 2320, the upper section 2310 is higher than the first air duct 21 and the second air duct 22, the lower section 2320 is lower than the upper section 2310 and communicates with the upper section 2310, the first motor 32 and the second motor 42 are both arranged in the upper section 2310, and the electric control assembly 5 is arranged in the lower section 2320. In this way, the structure of the third air duct 23 is simple, the airflow path is short, the two motors and the electric control assembly 5 can be effectively cooled, the cooling efficiency is high, and the occupied space is small. In addition, it can be understood that in the embodiment, if the first fan wheel 31 and the second fan wheel 41 are axial-flow fan wheels with the axis extending in the up-down direction, and the first motor 32 and the second motor 42 are located on the upper side of the first fan wheel 31 and the second fan wheel 41 respectively, the upper section 2310 can serve as the first section 231, and the lower section 2320 can serve as the second section 232. Of course, it is not limited to this, in the embodiment, the first fan wheel 31 and the second fan wheel 41 are not limited to be axial-flow fan wheels, but can also be other types of fan wheels, which will not be repeated here.

[0091] Optionally, as shown in the drawings, Figure 3 The third air inlet 13 can be arranged above at least one of the first air inlet 111 and the second air inlet 121 and opposite to the upper section 2310, and the third air outlet 24 is arranged below the upper section 2310. In this way, the airflow path of the third air duct 23 can be further shortened, the airflow can be simply and effectively ensured to flow through the lower section 2320 and the upper section 2310, the cooling efficiency is higher, the required energy consumption is lower, and the negative pressure of the second air duct 22 can be better and effectively utilized to realize the heat dissipation and ventilation of the third air duct 23.

[0092] Of course, the present application is not limited to this, for example, in other embodiments of the present application, as shown in the drawings, Figure 17 The third air duct 23 can also not include the upper section 2310, but only include the lower section 2320, at this time, the housing assembly 1 can have a separate space instead of the position of the upper section 2310, the first motor 32 and the second motor 42 are both arranged in the separate space, and the separate space is not communicated with the lower section 2320.

[0093] In some embodiments of the present application, as shown in the drawings, Figures 16-17 The third air inlet 13 is arranged to be spaced apart from the first air inlet 111 and the second air inlet 121 and faces the electric control assembly 5. That is, the third air inlet 13 is not arranged in the extension area of the edge of the first air inlet 111, nor is it arranged in the extension area of the edge of the second air inlet 121, but is spaced apart from the first air inlet 111 and the second air inlet 121, and is not arranged next to them. In this way, the distance between the third air inlet 13 and the heat source in the third air duct 23 can be as close as possible, thereby improving the cooling efficiency.

[0094] For example, in some embodiments, such as Figures 16-17 As shown, the electronic control component 5 may include a heat sink 52, and at least a portion of the third air inlet 13 is disposed opposite to the heat sink 52, that is, when projected onto a plane perpendicular to the air intake direction of the third air inlet 13, at least a portion of the projected projection of the third air inlet 13 coincides with the projected projection of the heat sink 52. Therefore, by providing the heat sink 52 and distributing at least a portion of the third air inlet 13 opposite to it, the heat dissipation efficiency of the electronic control component 5 can be improved more effectively.

[0095] Regardless of the relationship between the third air inlet 13 and the first air inlet 111 and the second air inlet 121, in some embodiments of the present invention, such as Figure 3 As shown, the third air inlet 13 can be higher than the electronic control component 5, and the third air outlet 24 can include a lower air outlet area 242 set below the electronic control component 5, that is, the lower end of the lower air outlet area 242 is lower than the lower end of the electronic control component 5. Therefore, while ensuring a short airflow path for the third air duct 23, the airflow can flow as far as possible through the area of ​​the heat source where the third air duct 23 is located, improving heat dissipation efficiency while reducing energy consumption. This allows for better and more effective utilization of the negative pressure of the second air duct 22 to achieve heat dissipation and ventilation in the third air duct 23.

[0096] Furthermore, such as Figure 3 As shown, the third air outlet 24 may further include an upper air outlet area 241 that covers at least a portion of the height region where the electronic control component 5 is located in the vertical direction. That is, when projected onto a plane perpendicular to the air outlet direction of the third air outlet 24, the height range of the projected image of the third air outlet 24 at least partially overlaps with the height range of the projected image of the electronic control component 5. This allows for more effective heat dissipation for the electronic control component 5.

[0097] In some embodiments of the present invention, such as Figures 9-11 As shown, the electronic control component 5 includes an electronic control box 51, which has a heat dissipation air inlet 511 and a heat dissipation air outlet 512. Along the airflow path from the third air inlet 13 to the third air outlet 24, the heat dissipation air inlet 511 is located upstream of the heat dissipation air outlet 512. Thus, when the airflow flows through the third air duct 23, it can also enter the electronic control box 51 through the heat dissipation air inlet 511, exchange heat more effectively with the components inside the electronic control box 51, and more effectively remove the heat from the electronic control component 5. Then, the heat is discharged to the outside of the electronic control box 51 through the heat dissipation air outlet 512, and then discharged from the second air duct 22 through the third air duct 23, further improving the heat dissipation efficiency of the electronic control component 5.

[0098] Further optional, such as Figures 9-11As shown, the heat dissipation air inlet 511 and the heat dissipation air outlet 512 are respectively located at opposite sides of the electric control box 51, and the electric control box 51 is further provided with a heat dissipation vent hole 513 on the side between the heat dissipation air inlet 511 and the heat dissipation air outlet 512. Thus, the heat dissipation vent hole 513 can be further used to improve the heat dissipation efficiency of the components in the electric control box 51 without affecting the air flow through the electric control box 51. It can be understood that if the heat dissipation air inlet 511 and the heat dissipation air outlet 512 are respectively located at the upper and lower sides of the electric control box 51, the left side, the right side, the front side and the rear side between the heat dissipation air inlet 511 and the heat dissipation air outlet 512 are suitable for the side surface.

[0099] In addition, in some embodiments, as shown in Figure 4 As shown, the third air duct 23 can be provided with a bracket 26, and the electric control assembly 5 is installed on the bracket 26, and the bracket 26 is provided with a flow hole 261. Thus, on the one hand, the installation requirement of the electric control assembly 5 is met, and on the other hand, the ventilation and heat dissipation requirement of the electric control box 51 is met.

[0100] Next, an integrated air conditioner 100 according to several specific embodiments of the present application is described.

[0101] Embodiment one

[0102] As shown in Figures 1-11 The integrated air conditioner 100 is a window machine, and the shell assembly 1 includes a front shell 11, a rear shell 12 and a bottom plate 14. The front shell 11 and the rear shell 12 are arranged on the bottom plate 14, and the bottom plate 14 is further provided with an air duct assembly 2. The bottom plate 14, the front shell 11, the rear shell 12 and the air duct assembly 2 jointly define a first air duct 21, a second air duct 22 and a third air duct 23 inside the shell assembly 1. The front shell 11 has a first air inlet 111 and a first air outlet 112 which communicate with the first air duct 21, and the first air inlet 111 and the first air outlet 112 are arranged to face the indoor air inlet and air outlet. The rear shell 12 has a second air inlet 121 and a second air outlet 122 which communicate with the second air duct 22, and the second air inlet 121 and the second air outlet 122 are arranged to face the outdoor air inlet and air outlet. Thus, the front shell 11 and the rear shell 12 are arranged to realize the circulation of air in and out of the machine in the front and rear directions of the machine, respectively.

[0103] The front shell 11 is provided with a first grating area 113, and the first air inlet 111 is arranged in the first grating area 113. The upper part of the first grating area 113 is provided with a third air inlet 13 which communicates with the third air duct 23. That is, the first grating area 113 is formed with the first air inlet 111 at the area opposite to the first air duct 21, and the part of the first grating area 113 which is higher than the first air duct 21 is formed with the third air inlet 13. The rear shell 12 is provided with a second grating area 123, and the second air inlet 121 is arranged in the second grating area 123.

[0104] The air duct assembly 2 is disposed within the housing assembly 1, and a first air duct 21 is defined between the air duct assembly 2 and the front housing 11. A second air duct 22 is formed between the air duct assembly 2 and the rear housing 12. The first air duct 21 is located on the front right side of the second air duct 22. The third air duct 23 includes an upper section 2310 located above the first air duct 21 and the second air duct 22, and a lower section 2320 located on the front left side of the second air duct 22. The lower section 2320 is located on the left side of the first air duct 21. A first impeller 31 and a first heat exchanger 6 are disposed within the first air duct 21. A second impeller 41 and a second heat exchanger 7 are disposed within the second air duct 22. A first motor 32 and a second motor 42 are disposed in the upper section 2310 of the third air duct 23. The first motor 32 is connected to the first impeller 31 to drive the first impeller 31 to rotate, and the second motor 42 is connected to the second impeller 41 to drive the second impeller 41 to rotate. A mounting cavity is provided below the first air duct 21, and a compressor 8, etc., are disposed within the mounting cavity.

[0105] The air duct assembly 2 includes a motor base 25, which defines the top walls of the first air duct 21 and the second air duct 22. The first motor 32 and the second motor 42 are both located above the motor base 25. A first air inlet 111 is formed in the area of ​​the first grille region 113 below the motor base 25, and a third air inlet 13 is formed in the part of the first grille region 113 above the motor base 25. A notch 251 is formed on one corner of the motor base 25 near the front housing 11. The third air duct 23 includes an upper section 2310 above the motor base 25 and a lower section 2320 below the motor base 25. The first motor 32 and the second motor 42 are located in the upper section 2310, and the electronic control assembly 5 is located in the lower section 2320. Airflow enters the upper section 2310 from the third air inlet 13 and then enters the lower section 2320 from the upper section 2310. The notch 251 allows airflow to pass through the upper section 2310 and the lower section 2320.

[0106] A third air outlet 24 is opened on the air duct assembly 2. As the second impeller 41 in the second air duct 22 rotates and circulates the airflow of the second air duct 22, the airflow of the second air duct 22 is used to guide and carry away the airflow of the third air duct 23, so that a negative pressure state is formed inside the third air duct 23. This allows airflow to be continuously drawn into the third air duct 23 from the third air inlet 13. The airflow circulation in the third air duct 23 carries away the heat dissipated by the first motor 32, the second motor 42 and the electronic control assembly 5 in the third air duct 23.

[0107] The air duct assembly 2 and the front shell 11 have a cavity, which is the lower section 2320, and the electric control assembly 5 is arranged in the cavity. Specifically, the air duct assembly 2 is provided with a bracket 26, the electric control assembly 5 is installed on the bracket 26, and the bracket 26 is provided with an overflow hole 261. The electric control assembly 5 can include an electric control box 51 and electric control components such as a mainboard arranged inside the electric control box 51. The electric control assembly 5 further includes a heat sink 52 exposed outside the electric control box 51, for example, a mainboard heat sink 52. The surface of the electric control box 51 is provided with a heat dissipation air inlet 511, a heat dissipation air outlet 512, and a heat dissipation vent hole 513. The heat dissipation air inlet 511 and the heat dissipation air outlet 512 are arranged at the top and bottom of the electric control box 51, respectively, and face each other, so that the air flow enters from the top and flows out from the bottom, which is conducive to the heat dissipation of the internal components of the electric control box 51. The rear surface of the electric control box 51 faces the air duct assembly 2, and the heat dissipation vent hole 513 is formed in the front surface of the electric control box 51, thereby assisting the heat dissipation of the electric control box 51 and the air flow into the electric control box 51.

[0108] Therefore, under the action of the second fan assembly, the indoor air enters the upper section 2310 from the third air inlet 13, carries away the heat of the first motor 32 and the second motor 42, and then flows to the gap 251 of the motor seat 25, and then flows downward into the lower section 2320. Part of the air flow entering the lower section 2320 passes through the electric control box 51 from the inside of the electric control box 51, and the remaining part passes through the heat exchange with the heat sink 52 from the outside of the electric control box 51. After that, these air flows flow out to the second air duct 22 through the third air outlet 24 on the air duct assembly 2, thereby realizing the continuous flow of the air flow in the third air duct 23.

[0109] In summary, in the first embodiment, the third air inlet 13 is arranged on the top of the first air inlet 111 of the front shell 11, and communicates with the upper section 2310 formed between the motor seat 25 and the shell assembly. The first motor 32 and the second motor 42 are arranged in the upper section, and the lower section 2320 is formed between the air duct assembly 2 and the front shell 11. The electronic control assembly 5 is arranged in the lower section 2320. The third air outlet 24 is arranged on the air duct assembly 2 and communicates with the lower section 2320 and the second air duct 22. The third air outlet 24 is used to guide the air flow in the entire third air duct 23, so that the negative pressure is formed in the third air duct 23. The third air duct 23 can introduce the air flow from the third air inlet 13 and discharge the air flow through the third air outlet 24, so as to drive the third air duct 23 to continuously flow, thereby taking away the heat emitted by the first motor 32, the second motor 42 and the electronic control assembly 5 in the third air duct 23, and maintaining the stable operation of the entire machine. Since the air flow of the third air duct 23 for heat dissipation starts immediately after the start of the entire machine and stops immediately after the end of the entire machine, the air flow of the second air duct 22 is originally necessary for the air conditioner all-in-one machine to realize the heat exchange function, so that the entire heat dissipation operation does not increase the additional equipment investment. Moreover, the third air inlet 13 of the third air duct 23 is integrated with the first air inlet 111 in the same area, which maintains the cleanliness and coordination of the appearance design, and does not affect the appearance of the entire machine. Moreover, the third air outlet 24 is away from the electronic control assembly 5, so as to prevent liquid from splashing on the electronic control assembly 5, thereby achieving effective electrical safety protection performance.

[0110] Embodiment two

[0111] Specifically, the air flow introduced by the third air duct 23 is not limited to only coming from the indoor, for example, in the second embodiment, the third air duct 23 can also introduce the air flow from the outdoor. For simplicity of description, only the differences between the second embodiment and the first embodiment are described below, and the same parts are not described. Figures 12-13 As shown, the area of the first grid area 113 at the top of which the third air inlet 13 is arranged is cancelled, and the top of the second grid area 123 is arranged to be higher than the motor seat 25. The third air inlet 13 is arranged on the part of the second grid area 123 which is higher than the motor seat 25.

[0112] Embodiment three

[0113] Specifically, the air flow introduced by the third air duct 23 is not limited to only coming from the outdoor, for example, in the third embodiment, the third air duct 23 can also introduce the air flow from the indoor and the air flow from the outdoor. For simplicity of description, only the differences between the third embodiment and the first embodiment are described below, and the same parts are not described. Figures 14-15As shown, the top of the first grid area 113 is arranged with the area where the third air inlet 13 is arranged, while the top of the second grid area 123 is arranged higher than the motor seat 25, and the third air inlet 13 is arranged in the part of the second grid area 123 which is higher than the motor seat 25. That is, the top of the first grid area 113 and the top of the second grid area 123 are both raised to arrange the third air inlet 13 respectively, so that the third air duct 23 can introduce airflow from both indoor and outdoor. In this way, the air inlet efficiency of the third air duct 23 can be improved.

[0114] Embodiment Four

[0115] Specifically, the airflow introduced by the third air duct 23 is not limited to only come from the top of the first air duct 21 and the second air duct 22, for example, as shown in Figures 16-18 When the first motor 32 and the second motor 42 do not need to be cooled by the third air duct 23, the gap 251 of the motor seat 25 can be sealed, the upper section 2310 is no longer communicated with the lower section 2320, and the upper section 2310 no longer belongs to the third air duct 23, only the lower section 2320 belongs to the third air duct 23. Therefore, in this embodiment four, the area where the top of the first grid area 113 is arranged with the third air inlet 13 is cancelled, and the area where the top of the second grid area 123 is arranged with the third air inlet 13 is also cancelled. At the same time, the third air inlet 13 is arranged in the local area of the front shell 11 opposite to the electronic control box 51, so that the third air inlet 13 is located at the front side of the electronic control box 51.

[0116] At this time, in order to avoid liquid and the like from splashing onto the electronic control box 51 from the third air inlet 13, a waterproof deflector and the like can be arranged at the third air inlet 13, thereby improving safety. In addition, in this embodiment four, when the third air inlet 13 is located at the front side of the electronic control assembly 5, the heat dissipation vent can be arranged at the rear side of the electronic control box 51, thereby playing a waterproof effect on the one hand, and ensuring the ventilation and heat dissipation effect on the other hand.

[0117] Of course, the present application is not limited thereto, and in other embodiments of the present application, the third air inlet 13 can also be arranged in the area of the front shell 11 opposite to the front side of the electronic control assembly 5 and lower, or the side of the front shell 11 away from the first air inlet 111 (for example Figure 16 the left area of the front shell 11 shown in the above embodiment three), or other areas of the rear shell 12, and the like, and the like, which will not be repeated here.

[0118] In the description of the application, it is to be understood that the orientations or positional relationships indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the devices or elements indicated thereby must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the application.

[0119] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.
