Description

Technical Field

[0001] The utility model relates to the technical field of heating, ventilation and air conditioning (HVAC) equipment, in particular to an outdoor unit of HVAC equipment and HVAC equipment. Background Art

[0002] The information provided in this part is only background information related to the present disclosure, and it is not necessarily prior art.

[0003] The outdoor unit of HVAC equipment includes structures such as a box body, a compressor and a heat exchanger located inside the box body. The outdoor unit of HVAC equipment is usually connected to the indoor unit of HVAC equipment to achieve a refrigeration cycle.

[0004] The first ventilation opening of the outdoor unit of HVAC equipment is the part for discharging heat and exhausting the treated air. The first ventilation opening of the existing outdoor unit of HVAC equipment is in an always-open state. Although there are protection structures such as grilles, when the outdoor unit of HVAC equipment is not operating, foreign objects are still likely to enter the machine body through the first ventilation opening. The foreign objects are likely to affect the heat dissipation efficiency of the outdoor unit, resulting in a decrease in refrigeration capacity and energy efficiency, and even easily damaging the outdoor unit of HVAC equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to at least solve the problem that foreign objects are likely to enter the machine body through the first ventilation opening when the existing outdoor unit of HVAC equipment is not operating. This purpose is achieved by the following technical solutions:

[0006] In a first aspect, the utility model provides an outdoor unit of HVAC equipment, including a box body, a compressor, a heat exchanger, a fan assembly and an opening and closing device.

[0034] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0035] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. Method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order described or illustrated, unless an execution order is explicitly stated. It should also be understood that additional or alternative steps may be used.

[0036] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first", "second", and other numerical terms do not imply an order or sequence when used herein. Thus, a first element, component, region, layer, or section discussed below may be referred to as a second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0037] For ease of description, spatial relative relationship terms may be used herein to describe the relationship of one element or feature shown in the figures to another element or feature, such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", etc. Such spatial relative relationship terms are intended to include different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "beneath" another element or feature will then be oriented "above" or "over" the other element or feature. Thus, the example term "below" can include both upward and downward orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relationship descriptors used herein are to be interpreted accordingly.

[0038] When the outdoor unit of a heating, ventilation, and air conditioning (HVAC) device is in operation, it usually has a relatively large air outlet area. When the air outlet is discharging air, it can blow away most foreign matters such as dust. When the air outlet stops discharging air, although barriers such as grilles can block large particles of foreign matters, it is still inevitable for foreign matters to enter the machine body through the air outlet, which will affect the operation and safety of the outdoor unit of the HVAC device.

[0039] In view of this, the present embodiment provides an outdoor unit of a heating, ventilation and air conditioning (HVAC) device, aiming to design a structure of an outdoor unit of an HVAC device that opens the air outlet when the outdoor unit of the HVAC device starts to operate and closes the air outlet when the outdoor unit of the HVAC device stops, preventing foreign objects from entering through the air outlet.

[0040] The following will introduce the outdoor unit of the HVAC device provided in the present embodiment in conjunction with the attached Figures 1-7 drawings.

[0041] In conjunction with the attached Figures 1-4 drawings, as shown, the present embodiment provides an outdoor unit 100 of an HVAC device, which includes functional structures such as a box body 10, a compressor 20, a heat exchanger 30, a fan assembly 40, and an opening and closing device 50.

[0042] Among them, the shape of the box body 10 in this embodiment is not limited. It can be a rectangular or approximately rectangular box body 10 structure as shown in the figure, or other shapes. The material of the box body 10 can be metal, plastic, etc., and this embodiment will not list them one by one.

[0043] An accommodation cavity is provided inside the box body 10, and a first ventilation opening 131 and a second ventilation opening (not shown in the figure) communicating with the accommodation cavity are provided. The first ventilation opening 131 and the second ventilation opening can be opening structures directly formed on the side wall of the box body 10, or the first ventilation opening 131 and the second ventilation opening surrounded by multiple side walls of the box body 10. One of the first ventilation opening 131 and the second ventilation opening in this embodiment is the air outlet, and the other is the air inlet. The second ventilation opening can be provided on the side of the box body 10 adjacent to the first ventilation opening 131 ( Figure 3 and 4 the left side in the figure). This embodiment describes the case where the first ventilation opening 131 is the air outlet as an example.

[0044] The compressor 20 and the heat exchanger 30 in this embodiment are located in the accommodation cavity. The compressor 20 can be located Figure 4 on the right side of the fan in Figure 4 the figure. The heat exchanger 30 is arranged around the fan and at least partially located

[0045] behind the fan in the figure. The compressor 20 and the heat exchanger 30 are connected by pipelines. The numbers of the compressor 20 and the heat exchanger 30 are both at least one. When the number of the heat exchanger 30 is one, the heat exchanger 30 can be a condenser. The compressor 20 is connected to the condenser of the outdoor unit 100 of the HVAC device and communicates with the evaporator of the indoor unit of the HVAC device, thereby forming a refrigeration cycle.

[0046] Since the compressor 20 and the heat exchanger 30 are structures well-known to those skilled in the art, the specific structures and working principles of the above three components are not described in this embodiment.

[0047] The number of the opening and closing devices 50 in this embodiment can be one or two. For example, the number of the opening and closing devices 50 can be designed as two, one is installed at the first ventilation opening 131 and the other is installed at the second ventilation opening. In some embodiments, the number of the opening and closing devices 50 is one, and the opening and closing device 50 is only installed at the air outlet because the area of the air outlet is larger than that of the air inlet, making it easier for impurities to enter.

[0048] The opening and closing device 50 in this embodiment is configured to keep the first ventilation opening 131 in an open state or a closed state. When the outdoor unit 100 of the heating and ventilation equipment is operating, the opening and closing device 50 can keep the first ventilation opening 131 in an open state, and the first ventilation opening 131 is communicated with the outside, so as to realize the air inlet and outlet circulation of the outdoor unit 100 of the heating and ventilation equipment. When the outdoor unit 100 of the heating and ventilation equipment stops operating, the opening and closing device 50 can keep the first ventilation opening 131 in a closed state, cut off the communication between the first ventilation opening 131 and the outside, prevent foreign objects from entering the outdoor unit 100 of the heating and ventilation equipment through the first ventilation opening 131, reduce the possibility of foreign objects entering the box body 10, and thus reduce the possibility of foreign objects affecting the operation of the outdoor unit 100 of the heating and ventilation equipment or even damaging the outdoor unit 100 of the heating and ventilation equipment.

[0049] Moreover, when the first ventilation opening 131 in this embodiment is an air outlet, the airflow flowing out of the first ventilation opening 131 can blow away foreign objects such as dust when the foreign objects enter the vicinity of the first ventilation opening 131, so as to reduce the possibility of foreign objects entering the accommodation cavity through the first ventilation opening 131 when the first ventilation opening 131 is in an open state. Therefore, after the opening and closing device 50 is configured, whether the first ventilation opening 131 is in a closed state or an open state, the possibility of foreign objects entering the accommodation cavity through the first ventilation opening 131 can be effectively reduced.

[0050] Combined with the attached Figure 5 As shown, in some examples, optionally, the opening and closing device 50 includes an opening and closing component 51 and a panel 52. The opening and closing component 51 is connected to the box body 10, the panel 52 is installed on the opening and closing component 51, and the size of the panel 52 is larger than that of the first ventilation opening 131 so that the panel 52 can close the first ventilation opening 131.

[0051] The opening and closing component 51 in this embodiment is configured to drive the panel 52 to move between a first position and a second position. Combined with the attached Figure 2 As shown, the panel 52 is in Figure 2When in the first position in [description], the panel 52 has a ventilation gap with the first ventilation opening 131, and air can flow out through the ventilation gap between the panel 52 and the first ventilation opening 131. Moreover, by adjusting the size of the ventilation gap between the panel 52 and the first ventilation opening 131, the wind speed and air volume can be adjusted. When the first ventilation opening 131 in this embodiment is an air outlet, the air flow blows from the air inlet towards the ventilation gap and finally flows to the outside, which can prevent foreign matters such as dust from entering the first ventilation opening 131. At this time, the first ventilation opening 131 is in an open state.

[0052] The panel 52 is at Figure 1 the second position, the panel 52 itself or in cooperation with the box body 10 closes the first ventilation opening 131. At this time, the first ventilation opening 131 is in a closed state.

[0053] There are various structural forms of the opening and closing component 51 in this embodiment, as long as it can drive the panel 52 between the first position and the second position. For example, the opening and closing component 51 can directly be a telescopic component such as a pneumatic rod or a hydraulic rod. For another example, the opening and closing component 51 can also include a motor and a reciprocating linear motion mechanism connected to each other. The reciprocating linear motion mechanism can be a mechanism such as a lead screw or a crank connecting rod that converts rotary motion into linear motion.

[0054] For the convenience of connection and installation, in some examples, optionally, the opening and closing component 51 of this embodiment includes a first connecting piece 511, a telescopic piece 512, and a second connecting piece 513. Both the first connecting piece 511 and the second connecting piece 513 can be structures with an overall contour approximately in the shape of a plate or a strip. The first connecting piece 511 and the second connecting piece 513 are arranged in parallel at intervals along the first direction X. The first direction X is the arrangement direction from the accommodation cavity to the panel 52. In some embodiments, the first direction X can be the thickness direction of the box body 10.

[0055] The connection manner of the first connecting piece 511 of this embodiment with the box body 10 can be a fixed connection or a detachable connection. The ways of fixed connection include welding, riveting, etc. The ways of detachable connection include snap connection or threaded connection, etc.

[0056] The telescopic piece 512 of this embodiment is located between the first connecting piece 511 and the second connecting piece 513. One end of the opposite ends of the telescopic piece 512 is connected to the first connecting piece 511, and the other end is connected to the second connecting piece 513. The connection manner can be a fixed connection or the following hinge connection. In some embodiments, the telescopic piece 512 can be a structure such as the above-mentioned pneumatic rod or hydraulic rod.

[0057] In order to improve the stability of the panel 52 when installed on the opening and closing component 51 and the stability when moving, in some examples, optionally, the opening and closing component 51 of this embodiment also includes a supporting mechanism 514, and the supporting mechanism 514 is located between the first connecting member 511 and the second connecting member 513, and one end of the supporting mechanism 514 is connected to the first connecting member 511, and the other end is connected to the second connecting member 513, and retracts when the first connecting member 511 and the second connecting member 513 approach each other, and extends when the first connecting member 511 and the second connecting member 513 move away from each other.

[0058] It should be understood that the “retraction” and “extension” in this embodiment should be understood as the expansion and contraction of the size of the entire support mechanism 514 in the first direction X, and does not necessarily mean that each component of the support mechanism 514 must be expanded and contracted separately.

[0059] There are many specific implementations of the support mechanism 514. For example, the support mechanism 514 can be a spring structure that is telescopic in the axial direction and cannot be deformed in the radial direction. For another example, the support mechanism 514 can be two rods forming an eight-shaped shape, one end of the two rods is hinged to the first connecting member 511, and the other end is slidably connected to the second connecting member 513 (the above two implementations are not shown in the figure).

[0060] Combined with Figures 5-7 As shown, in some examples, optionally, the support mechanism 514 of the present embodiment includes at least one scissors frame 5141, and the scissors frame 5141 includes a first support member 51411 and a second support member 51412 forming an x-shaped structure. The first support member 51411 and the second support member 51412 can both be rod-shaped, and one of the opposite ends of the first support member 51411 is hinged to the first connecting member 511, and the other end is connected to the second connecting member 513 in a manner that can slide along the length direction of the second connecting member 513. Accordingly, one end of the second support member 51412 is hinged to the second connecting member 513, and the other end is connected to the first connecting member 511 in a manner that can slide along the length direction of the first connecting member 511. The first support member 51411 is hinged to the middle part of its own length direction and the second support member 51412 is hinged to the middle part of its own length direction.

[0061] When the first connecting member 511 and the second connecting member 513 approach each other, the first supporting member 51411 rotates relative to the first connecting member 511 in a first circumferential direction, and slides relative to the second connecting member 513 along a component direction of the length direction of the second connecting member 513, and the second supporting member 51412 rotates relative to the second connecting member 513 in a second circumferential direction opposite to the first circumferential direction, and slides relative to the first connecting member 511 along a component direction of the length direction of the first connecting member 511, so that the scissors frame 5141 as a whole shrinks in size along the first direction X.

[0062] Similarly, when the first connecting member 511 and the second connecting member 513 move away from each other, the first support member 51411 rotates relative to the first connecting member 511 in the second circumferential direction and slides relative to the second connecting member 513 in the other component direction along the length direction of the second connecting member 513. The second support member 51412 rotates relative to the second connecting member 513 in the first circumferential direction and slides relative to the first connecting member 511 in the other component direction along the length direction of the first connecting member 511, so that the overall size of the scissors frame 5141 in the first direction X elongates.

[0063] In some embodiments, the length directions of the first connecting member 511 and the second connecting member 513 are the same, and the length direction of the first connecting member may intersect the first direction X. Intersecting means that the two directions form an angle less than or equal to 90°. Specifically, the length direction of the first connecting member 511 may be perpendicular to the first direction X.

[0064] During the above-mentioned contraction process of the scissors frame 5141 as the first connecting member 511 and the second connecting member 513 approach or move away from each other, better support can be provided for the movement of the second connecting member 513.

[0065] In order to reduce the space occupied by the telescopic member 512 in the first direction X, the telescopic member 512 can be designed such that the length direction forms an angle less than 90° with the length directions of the first connecting member 511 and the second connecting member 513 respectively, that is, the telescopic member 512 is inclined with respect to the first connecting member 511 and the second connecting member 513.

[0066] Correspondingly, under the condition that the telescopic member 512 is inclined as described above, in order not to affect the movement of the telescopic member 512, one end of the two opposite ends of the telescopic member 512 can be hinged to the first connecting member 511, and the other end can be hinged to the second connecting member 513, so that the overall telescopic member 512 can rotate relative to the first connecting member 511 and slide relative to the second connecting member 513, so as to make the telescopic member 512 form a smaller angle with the first connecting member 511 and the second connecting member 513 to adapt to the change in the distance between the first connecting member 511 and the second connecting member 513.

[0067] In some examples, optionally, along the second direction Y, a plurality of scissors frames 5141 of each opening and closing assembly 51 are arranged at intervals. For example, two in the figure. The first support members 51411 of one scissors frame 5141 among two adjacent scissors frames 5141 are parallel to the first support members 51411 of the other scissors frame 5141, and the second support members 51412 of one scissors frame 5141 among two adjacent scissors frames 5141 are parallel to the second support members 51412 of the other scissors frame 5141.

[0068] In the second direction Y, multiple scissors frames 5141 can better support the first connecting member 511 and the second connecting member 513, further improving the stability of the second connecting member 513 and the panel 52 during movement.

[0069] The second direction Y intersects the first direction X and intersects the length direction of the first connecting member 511. In some embodiments, the second direction Y is perpendicular to the first direction X, perpendicular to the length direction of the first connecting member 511 and the length direction of the second connecting member 513. The second direction Y can be the width direction of the box body 10.

[0070] Furthermore, along the length direction of the first connecting member 511, multiple scissors frames 5141 of this embodiment can be provided. The multiple scissors frames 5141 are arranged at intervals along the length direction of the first connecting member 511 between the first connecting member 511 and the second connecting member 513. For example, each opening and closing assembly 51 has two groups in the length direction of the first connecting member 511. The two groups of scissors frames 5141 are correspondingly arranged at both ends of the first connecting member 511 and the second connecting member 513 along the length direction of the first connecting member 511. Each group of scissors frames 5141 has two scissors frames 5141 along the second direction Y.

[0071] To improve the support stability of the opening and closing assembly 51 for the panel 52, the number of the opening and closing assemblies 51 can also be designed to be multiple. For example, the number of the opening and closing assemblies 51 in the figure is two, and the two opening and closing assemblies 51 are respectively connected to both sides of the panel 52 along the second direction Y.

[0072] Again referring to the attached Figure 3 As shown, in some examples, optionally, the box body 10 of this embodiment includes a top wall 11, a bottom wall 12, and a plurality of side walls connected between the top wall 11 and the bottom wall 12. The top wall 11, the bottom wall 12, and the plurality of side walls enclose the above-mentioned accommodation cavity. The plurality of side walls include a first wall 13 facing the panel 52. The first wall 13 is provided with the above-mentioned first ventilation opening 131. The fan assembly 40 can be arranged facing the first ventilation opening 131. The opening and closing device 50 is installed on the first wall 13. The panel 52 and the first wall 13 form a double protection for the internal structure.

[0073] Furthermore, the bottom wall 12, the top wall 11, and the other two side walls of the box body 10 are provided with an extending edge 14 arranged around the first wall 13. The extending edge 14 and the first wall 13 enclose an accommodation groove 15. The opening and closing device 50 is connected to the first wall 13.

[0074] When the opening and closing device 50 is in Figure 1In the closed state, the panel 52 is in the second position, and all or part of the opening and closing device 50 is located in the receiving groove 15. At this time, the panel 52 can directly fit against the first wall 13 to directly seal the first ventilation opening 131, thereby cutting off the connection between the first ventilation opening 131 and the outside. The panel 52 and the protruding edge 14 are sealed to play a role in secondary sealing. Or there is a small gap between the panel 52 and the first wall 13 along the first direction X. The dimension of this small gap along the first direction is smaller than the dimension of the ventilation gap along the first direction, and it is located in the space enclosed by the receiving groove 15 and the panel 52. At this time, the sealing of the first ventilation opening 131 is only achieved through the sealing of the receiving groove 15 and the panel 52, and the connection between the first ventilation opening 131 and the outside can also be cut off.

[0075] When the opening and closing device 50 is in Figure 2 In the open state, the panel 52 is in the first position. At this time, the panel 52 is separated from the receiving groove 15 so that a ventilation gap is formed between the panel 52 and the first ventilation opening 131.

[0076] It should be understood that the "sealing" in this embodiment should be understood in a broad sense, as long as it can play a certain role in isolation, that is, completely closing or partially closing the first ventilation opening 131.
