Description

Technical Field

[0001] The present application relates to the technical field of air treatment, and in particular to an air conditioner outdoor unit and an air conditioner. Background Art

[0002] An air conditioner is a device that uses a refrigeration cycle to control the temperature, humidity, and air supply of the indoor environment. The main components that form the refrigeration cycle include a compressor, a heat exchanger (condenser, evaporator), and a fan.

[0003] In the outdoor unit of the air conditioner, the electrical components in the electrical box will generate heat. In order to facilitate the heat dissipation of the components inside the electrical box, vents are generally set on the electrical box for ventilation and heat dissipation. When the vents are set close to the fan side, the heat dissipation effect is better, but on rainy days or when there is water on the fan blades, water droplets can easily enter the electrical box through the vents, so a waterproof cover needs to be set at the vents.

[0004] At present, the ventilation holes of electrical boxes are usually in the form of open holes or shutters. The shutters are generally arranged vertically or horizontally. Both forms require a complex waterproof cover structure to form a tortuous ventilation duct to achieve a waterproof effect, which results in a complex structure and high cost. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0025] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0026] The terms "first", "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] The air conditioner in this application performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0029] The compressor compresses the refrigerant gas in a low temperature and low pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0030] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0031] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0032] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0033] Reference Figures 1 to 4 According to some embodiments of the present application, the air conditioner includes an air conditioner outdoor unit 10 installed in an outdoor space. The air conditioner outdoor unit 10 is connected to an air conditioner indoor unit (not shown) installed in an indoor space through a pipe. The air conditioner outdoor unit 10 may be provided with a compressor, an outdoor heat exchanger, an outdoor fan, an expander and similar components of a refrigeration cycle, and the air conditioner indoor unit may also be provided with an indoor heat exchanger and an indoor fan.

[0034] The air conditioner outdoor unit 10 includes a housing 10, which forms the overall appearance of the air conditioner outdoor unit. The housing 10 includes a top cover 11 defining a top structure, a base defining a bottom structure, a front side plate 12 with an opening, a right side plate 13 located on the right side, and a strip plate 14 connected at the left rear corner.

[0035] The strip plate 14 is L-shaped and has a first left plate portion 141 forming a left surface and a first rear plate portion 142 forming a rear surface.

[0036] The left end of the front side plate 12 is connected to the second left plate portion 121, and the second left plate portion 121 forms part of the left surface. The space between the first left plate portion 141 and the second left plate portion 121 forms a left air inlet.

[0037] The second left plate portion 121 may be formed by bending the left end of the front side plate 12 backward.

[0038] The rear end of the right side plate 13 is connected to the second rear plate portion 131, and the second rear plate portion 131 forms part of the rear surface. The space between the first rear plate portion 142 and the second rear plate portion 131 forms a rear air inlet. The rear air inlet and the left air inlet are both air inlets of the air conditioner outdoor unit.

[0039] The second rear plate portion 131 may be formed by bending the rear end of the right side plate 13 toward the left.

[0040] The opening of the front side plate 12 can be connected to an air outlet grille 15, and the holes on the air outlet grille 15 form an air outlet of the outdoor unit of the air conditioner.

[0041] The inner side of the front side plate 12 may be connected to an air guide ring 16 . The air guide ring 16 is in a circular ring shape and is disposed corresponding to the air outlet grille 15 for guiding the air flow of the outdoor fan 30 .

[0042] The air conditioner outdoor unit includes an outdoor heat exchanger 20, which is disposed in the housing 10 and is used to absorb heat from the air introduced into the air inlet or transfer heat to the air.

[0043] The outdoor heat exchanger 20 is L-shaped, with one portion corresponding to the rear air inlet and the other portion corresponding to the left air inlet.

[0044] The outdoor unit of the air conditioner includes an outdoor fan 30, which is located between the outdoor heat exchanger 20 and the air outlet grille 15 and is used to drive air flow.

[0045] The outdoor fan 30 is connected to the housing 10 through a bracket 40. The upper end of the bracket 40 is connected to the front side plate 12, and the lower end of the bracket 40 is connected to the base. The outdoor fan 30 is connected to the middle of the bracket 40 in the vertical direction.

[0046] The outdoor fan 30 includes a motor and fan blades. The motor is fixed to the bracket 40 by fasteners such as screws. The fan blades are connected to the output shaft of the motor. Driven by the motor, the fan blades rotate, thereby driving the flow of air.

[0047] The portion of the fan blade close to the air outlet end is located in the air guide ring 16 , and under the guidance of the air guide ring 16 , the air flow of the fan blade flows toward the air outlet grille 15 .

[0048] When the outdoor fan 30 is working, the outdoor airflow exchanges heat with the outdoor heat exchanger 20 at the air inlet side, passes through the outdoor fan 30 and the air guide ring 16, and is blown out of the housing 10 through the air outlet grille 15.

[0049] A partition plate 17 is provided in the housing 10 . The front end of the partition plate 17 is connected to the front side plate 12 , and the rear end of the partition plate 17 is connected to the right end plate of the outdoor heat exchanger 20 .

[0050] The partition plate 17 divides the space in the housing 10 into a fan chamber and a compressor chamber. For example, the fan chamber is on the left and the compressor chamber is on the right. The outdoor heat exchanger 20, the outdoor fan 30, etc. are located in the fan chamber, and the pipelines of the compressor, the expansion valve, etc. are located in the compressor chamber.

[0051] Reference Figures 4 to 6 The air conditioner outdoor unit includes an electrical box 50, in which electrical components are installed for realizing the electrical control function of the air conditioner.

[0052] The electrical box 50 is installed in the housing 10. The electrical box 50 is located at the top of the partition plate 17, with the right side of the electrical box 50 located in the compressor cavity and the left side of the electrical box 50 located in the fan cavity.

[0053] The side wall of the electrical box 50 facing the outdoor fan 30 is the first side wall 51 , that is, the left side wall of the electrical box 50 in the figure is the first side wall 51 .

[0054] A first louver 52 is disposed on the first side wall 51 . The first louver 52 can connect the inside and outside of the electrical box 50 , so that the heat generated by the electrical components in the electrical box 50 can be ventilated and dissipated through the first louver 52 .

[0055] The structure of the first louver 52 is waterproof and can block rainwater or moisture on the fan blades to prevent external moisture from entering the electrical box 50 and affecting the electrical performance.

[0056] Since the first louver 52 is located on the side of the outdoor fan 30, when there is a lot of rain or the rotation speed of the fan blade is fast, moisture may still enter the electrical box 50 through the first louver 52. Therefore, it is necessary to set a waterproof cover 60 to further block moisture.

[0057] The air conditioner outdoor unit includes a waterproof cover plate 60. The waterproof cover plate 60 is connected to the outer side of the electrical box 50 corresponding to the first louver 52.

[0058] The waterproof cover plate 60 may be in a square box shape, and the space between the waterproof cover plate 60 and the first side wall 51 forms a ventilation duct 70 for heat dissipation airflow.

[0059] The bottom end of the waterproof cover plate 60 is open for air circulation. The first louver 52 and the ventilation duct 70 are used to realize the heat dissipation airflow circulation inside and outside the electrical box 50.

[0060] In the prior art, the first venetian blind 52 is usually arranged horizontally or vertically. When the first venetian blind 52 is arranged horizontally, that is, its opening faces downward, then the moisture entering the ventilation duct 70 from the bottom end of the waterproof cover plate 60 is likely to enter the electrical box 50 from the opening at the lower end of the first venetian blind 52. When the first venetian blind 52 is arranged vertically, that is, the opening faces one end horizontally, such as forward or backward, then the first venetian blind 52 has a relatively poor blocking effect on the moisture above. Therefore, in order to ensure the waterproof performance, the waterproof cover plate 60 needs to be designed with a more complex ventilation structure to prevent moisture from flowing to the first venetian blind 52 through the ventilation duct 70.

[0061] In some embodiments, reference Figure 7 and Figure 8 The first louver 52 is inclined from bottom to top toward the air outlet side, and its opening faces the air outlet side.

[0062] Compared with the arrangement in which the opening is completely facing the front or rear side, the opening of the first louver 52 is facing obliquely downward, which can effectively prevent moisture from above from entering the electrical box 50.

[0063] Since the airflow generated by the negative pressure of the outdoor fan on the first louver 52 is directed toward the air outlet side, and the opening of the first louver 52 is also directed toward the air outlet side, the airflow has a certain inhibitory effect on the flow of moisture toward the first louver 52, thereby increasing the waterproofness of the first louver 52.

[0064] According to an embodiment of the present application, the inclination angle a1 of the first louver 52 relative to the vertical direction may not be greater than the inclination angle a2 of the first louver 52 relative to the horizontal direction. The inclination angle a1 of the first louver 52 relative to the vertical direction is in the range of 0°<a≤45°.

[0065] According to an embodiment of the present application, the first louvers 52 are arranged in a plurality of lateral arrangements. The first louvers 52 can be arranged in a row and located in the middle of the first side wall 51. When the first louvers 52 are arranged in a row, their length can be relatively large, thereby increasing the ventilation area and ensuring the heat dissipation performance.

[0066] The first louver 52 is located higher on the first side wall 51. The distance from the center of the first louver 52 to the top of the first side wall 51 is smaller than the distance from the center of the first louver 52 to the bottom of the first side wall 51, so that the path of moisture flowing from the ventilation duct 70 to the first louver 52 can be extended.

[0067] On the basis of improving the waterproof property of the first louver 52, the structure of the waterproof cover plate 60 can be simplified in design.

[0068] In some embodiments of the present application, reference Figure 6 and Fig. 9The waterproof cover plate 60 includes a waterproof side plate 61 , and the waterproof side plate 61 is spaced apart from the first side wall 51 of the electrical box 50 , and the space forms part of the ventilation duct 70 .

[0069] The waterproof cover plate 60 includes a connecting side plate 62 , which extends from the top and both lateral ends of the waterproof cover plate 60 toward the electrical box 50 , thereby forming a cavity between the waterproof side plate 61 and the connecting side plate 62 .

[0070] The connecting side plate 62 is provided with an outward flange at one end close to the electrical box 50 , which abuts against the first side wall 51 , and then is connected or welded by fasteners such as screws to achieve the connection between the waterproof cover plate 60 and the electrical box 50 .

[0071] The waterproof cover plate 60 includes a waterproof bottom plate 63 , which extends from the bottom end of the waterproof side plate 61 to the bottom of the electrical box 50 . A gap is formed between the waterproof bottom plate 63 and the bottom wall of the electrical box 50 , and the gap forms part of the ventilation duct 70 .

[0072] In the projection of the bottom wall of the electrical box 50 , the waterproof bottom plate 63 overlaps with the bottom wall of the electrical box 50 .

[0073] Specific reference Figure 6 , Figure 6 The middle arrow indicates the flow path of moisture. If moisture flows to the first louver 52 through the ventilation duct 70, it needs to first flow horizontally in the ventilation duct 70 and then transform into an upward vertical flow. The moisture flow path undergoes multiple bends. The bent structure of the ventilation duct 70 makes it difficult for moisture to flow to the first louver 52, thereby ensuring the waterproof performance of the ventilation part of the electrical box 50.

[0074] In some embodiments, the waterproof side plate 61 and the waterproof bottom plate 63 are connected by a waterproof inclined plate 64, and the waterproof inclined plate 64 is inclined from top to bottom toward the direction close to the electrical box 50. There is a gap between the waterproof inclined plate 64 and the electrical box 50, and the gap forms part of the ventilation duct 70.

[0075] The provision of the waterproof side plate 61 has a guiding effect on the heat dissipation airflow in the ventilation duct 70, which can make the heat dissipation airflow flow more smoothly.

[0076] In addition, the provision of the waterproof side plate 61 also reduces the volume of the waterproof cover plate 60 and makes the structure more compact.

[0077] The air guide ring 16 is provided with a relief portion for avoiding the waterproof cover plate 60. Due to the provision of the waterproof side plate 61, the relief portion is relatively small, which reduces the influence of the relief portion on the air guide performance of the air guide ring 16.

[0078] In some embodiments, a second louver 641 may be provided on the waterproof inclined plate 64, and the second louver 641 may increase the connection position between the ventilation duct 70 and the outside world, so as to prevent the tortuous ventilation duct 70 from affecting the ventilation and heat dissipation efficiency of the electrical box 50. The structure of the second louver 641 may prevent moisture from entering the ventilation duct 70 to a certain extent.

[0079] The second louvers 641 are disposed transversely on the waterproof inclined plate 64, and the second louvers 641 can be disposed on the inner side of the waterproof inclined plate 64. The second louvers 641 can be disposed in two rows to increase the ventilation area and improve the ventilation and heat dissipation efficiency.

[0080] In some embodiments, the second louver 641 is disposed close to the lower end of the waterproof inclined plate 64 so that the distance between the second louver 641 and the first louver 52 is as far as possible, thereby preventing moisture from flowing from the second louver 641 to the first louver 52 .

[0081] The height of the second louver 641 is lower than that of the first side wall 51 , and the distance from the second louver 641 to the first louver 52 may also be increased.

[0082] At least part of the second louver 641 is located below the electrical box 50. In other words, in the projection of the bottom wall of the electrical box 50, the second louver 641 overlaps with the bottom wall of the electrical box 50, so that the path of the moisture from the second louver 641 to the first louver 52 becomes tortuous, that is, the moisture is blocked by the bottom wall of the electrical box 50 in the vertical direction when entering the ventilation duct 70 from the second louver 641, and cannot flow smoothly to the first louver 52.

[0083] In the present application, the first louver 52 is arranged at an angle, which has a good blocking effect on the moisture below and the moisture above, and can improve the waterproof performance.

[0084] In the present application, the first louver 52 is tilted and its open end faces the air outlet side of the air conditioner, and is combined with a simple waterproof cover 60 structure: the waterproof bottom plate 63 of the waterproof cover 60 is located below the electrical box 50, so that the path of moisture in the ventilation duct 70 becomes tortuous, which can meet the waterproof requirements of the electrical box 50, and has the advantages of good waterproof performance, simple structure and low cost.

[0085] In the present application, the waterproof side plate 61 and the waterproof bottom plate 63 of the waterproof cover plate 60 are connected by an inclined waterproof inclined plate 64 , which can reduce the volume of the waterproof cover plate 60 .

[0086] In the present application, an inclined waterproof inclined plate 64 is provided on the waterproof cover plate 60 , so that the avoidance portion on the lower left end of the waterproof cover plate 60 on the air guide ring 16 is relatively small, thereby reducing the influence of the avoidance portion on the air guide performance of the air guide ring 16 .

[0087] In the present application, a second shutter 641 is provided on the waterproof cover plate 60 , which can increase the connection position between the ventilation duct 70 and the outside world, and prevent the tortuous ventilation duct 70 from affecting the ventilation and heat dissipation of the electrical box 50 .

[0088] In the present application, the second louver 641 is disposed close to the lower end of the waterproof inclined plate 64 so that the distance between the second louver 641 and the first louver 52 is as far as possible, thereby preventing moisture from flowing from the second louver 641 to the first louver 52 .

[0089] In the present application, on the projection of the bottom wall of the electrical box 50, the second louver 641 overlaps with the bottom wall of the electrical box 50, so that the path of moisture from the second louver 641 to the first louver 52 becomes tortuous, that is, moisture entering the ventilation duct 70 from the second louver 641 is vertically blocked by the bottom wall of the electrical box 50, and cannot flow smoothly to the first louver 52.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
