Description

Technical Field

[0001] The present application relates to the technical field of heat pump units, and in particular to an outdoor heat pump unit. Background Art

[0002] As a key component in the heat pump system, the electrical box is mainly used to install and protect electrical equipment. It can prevent moisture, dust, impurities, etc. in the external environment from entering the electrical equipment, avoid damage to the electrical equipment, and thus ensure the normal operation of the heat pump system and extend its service life. Therefore, the waterproof structure of the electrical box needs to be paid special attention. Once water enters the electrical box, it will inevitably cause damage to the electrical components, thereby paralyzing the entire heat pump system. In the existing waterproof structure for the electrical box, often only one waterproof structure is set, and water is prevented from entering the electrical box by drainage. The waterproof structure designed in this way can only meet the normal waterproof standard. If the heat pump unit placed outdoors encounters heavy rain, one waterproof structure cannot be effectively waterproof. Utility Model Content

[0003] The purpose of the embodiment of the present application is to provide an outdoor heat pump unit, which can effectively prevent water from entering the electrical box by setting a first waterproof part and a second waterproof part to ensure the stable operation of the electrical box and the heat pump unit.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] In one aspect, an outdoor heat pump unit is provided, comprising: a column, a top surface of which is provided with a first locking hole, and a side surface of which is provided with a second locking hole;

[0006] A first waterproof member is locked in the first locking hole by a fastener, the first waterproof member comprises a first plate body arranged horizontally, a first waterproof folding edge extending downward from one side of the first plate body facing outward, and a second waterproof folding edge extending upward from the other side of the first plate body;

[0007] The second waterproof component is locked in the second locking hole by a fastener, and the second waterproof component includes a vertically arranged second plate body, a first guide portion extending obliquely inward from the upper side of the second plate body, and a second guide portion extending obliquely outward from the other side of the second plate body.

[0008] Furthermore, an angle α is formed between the first waterproof folded edge and the first plate body, and an angle β is formed between the second waterproof folded edge and the second plate body, wherein β≥α.

[0009] Furthermore, 45°≤α≤90°, 60°≤β≤125°.

[0010] Furthermore, a cover plate is included, and the second waterproof folded edge is at least partially in contact with the side wall of the cover plate.

[0011] Furthermore, it also includes a side plate, and the first waterproof folded edge abuts against the outer wall surface or the inner wall surface of the side plate.

[0012] Furthermore, it also includes a reinforcing rod, which is arranged on the side of the second plate body.

[0013] Furthermore, a third locking hole corresponding to the second locking hole is formed on the first plate body, and the fastener passes through the third locking hole and is locked in the second locking hole.

[0014] Furthermore, a mounting plate is provided on the top surface of the column, the first locking hole is opened on the mounting plate, and the height of the first air guide portion is lower than the height of the mounting plate.

[0015] Further, an angle γ is formed between the first guide portion and the second plate body, and an angle δ is formed between the second guide portion and the second plate body, wherein γ=δ.

[0016] Furthermore, 90°<γ≤150°.

[0017] The beneficial effects of the present application are as follows: the first waterproof member is locked on the first locking hole of the column by a fastener, and is mainly composed of a first plate body arranged horizontally, a first waterproof folding edge extending downward from the outward side of the first plate body, and a second waterproof folding edge extending upward from the other side of the first plate body. This design enables the first waterproof member to form a horizontal waterproof barrier, effectively preventing rainwater or external moisture from directly entering the interior of the electrical box from above; at the same time, the first waterproof folding edge and the second waterproof folding edge further enhance the waterproof effect, ensuring that moisture will not penetrate from the side or bottom. The second waterproof member is also locked on the second locking hole of the column by a fastener, and is composed of a second plate body arranged vertically, a first guide portion extending obliquely inward from the upward side of the second plate body, and a second guide portion extending obliquely outward from the other side of the second plate body. When moisture attempts to approach the electrical box from the side, the two guide portions of the second waterproof member can guide the moisture away from the electrical box to avoid direct contact with the electrical box, thereby playing a waterproof role. By setting up the first waterproof part and the second waterproof part, the present application realizes a double waterproof structure, greatly improving the waterproof effect. Even in harsh outdoor environments, such as heavy rain, it can effectively prevent moisture from entering the electrical box, ensuring the stable operation of the heat pump unit. In addition, the waterproof folding design of the first waterproof part and the guide part design of the second waterproof part both enhance the waterproof performance. These designs can ensure that moisture is effectively blocked or guided from multiple directions, further improving the waterproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0028] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0030] like Figure 1-Figure 7 As shown, this embodiment provides an outdoor heat pump unit, including: a column 1, a first waterproof component 2 and a second waterproof component 3, the top surface of the column 1 is provided with a first locking hole 101, and the side surface is provided with a second locking hole 102; the first waterproof component 2 is locked in the first locking hole 101 by a fastener, the first waterproof component 2 includes a horizontally arranged first plate body 201, a first waterproof folded edge 202 extending downward from the outward side of the first plate body 201, and a second waterproof folded edge 203 extending upward from the other side of the first plate body 201; the second waterproof component 3 is locked in the second locking hole 102 by a fastener, the second waterproof component 3 includes a vertically arranged second plate body 301, a first guide portion 302 extending obliquely inwardly from the upward side of the second plate body 301, and a second guide portion 303 extending obliquely outwardly from the other side of the second plate body 301.

[0031] Based on the above scheme, the first plate body 201 included in the first waterproof member 2 is horizontally arranged as the main waterproof panel, the first waterproof folding edge 202 extends downward from the outward side of the first plate body 201 to form a downward waterproof barrier to prevent moisture from dripping directly from the top into the electrical box, and the second waterproof folding edge 203 extends upward from the other side of the first plate body 201 to further prevent moisture from penetrating into the electrical box from the side. The second plate body 301 included in the second waterproof member 3 is vertically arranged to form a vertical waterproof barrier with the first waterproof member 2, the first guide part 302 extends obliquely inward from the upward side of the second plate body 301, when moisture approaches from the side, it can be guided inward and flow down along the second plate body 301 away from the electrical box, the second guide part 303 extends obliquely outward from the other side of the second plate body 301, and forms a symmetrical structure with the first guide part 302, ensuring that moisture can be effectively guided when approaching from any side. The first waterproof part 2 is locked to the first locking hole 101 of the column 1 by a fastener, and the second waterproof part 3 is locked to the second locking hole 102 of the column 1 by a fastener, ensuring the fixed connection between the two waterproof parts and the heat pump unit and the stability of the waterproof function. The first plate 201 of the first waterproof part 2 and its waterproof folding edge design form a waterproof barrier in the horizontal direction, effectively blocking the water dripping or infiltrating from the top and the side. The second plate 301 of the second waterproof part 3 and its guide part design form another waterproof barrier in the vertical direction, which can effectively guide the water approaching from the side and away from the electrical box. The first waterproof part 2 and the second waterproof part 3 form a double waterproof structure through synergy, ensuring the waterproof safety of the equipment inside the electrical box from multiple directions and angles. This double waterproof design realizes all-round protection of the electrical box of the outdoor heat pump unit through the carefully designed waterproof part structure and installation position, and can effectively prevent water from entering the electrical box in both the horizontal and vertical directions, thereby ensuring the stable operation of the heat pump unit and extending the service life of the equipment.

[0032] Furthermore, if Figure 4 As shown, an angle α is formed between the first waterproof fold 202 and the first plate 201, and an angle β is formed between the second waterproof fold 203 and the second plate 301, where β≥α. By forming an angle α, the first waterproof fold 202 can effectively divert water from above to prevent it from dripping directly onto the electrical box, and can ensure that when rainwater or other liquids approach from above, the water is effectively guided to the side or bottom of the electrical box, thereby avoiding direct contact with the equipment inside the electrical box. When β≥α, the second waterproof fold 203 forms a steeper angle. Such a design can increase the flow rate of rainwater or other liquids when flowing through the second waterproof fold 203, further reducing the time that water stays on the side of the electrical box, thereby reducing the risk of water infiltrating the electrical box.

[0033] In addition, by adjusting the size of α and β, the waterproof effect can be optimized according to different installation environments and usage requirements. For example, in areas with heavy rain, the angle of β can be increased to allow water to flow away from the electrical box faster; while in areas with less rain, the angles of α and β can be appropriately reduced to reduce the impact of wind resistance and other factors on waterproof performance.

[0034] Specifically, 45°≤α≤90°, 60°≤β≤125°. When α=45°, the angle between the first waterproof folded edge 202 and the first plate body 201 is moderate, which can better guide the water to flow away from the top while maintaining a certain structural stability. When α gradually increases to 90°, the first waterproof folded edge 202 gradually becomes a vertical state, and the waterproof folded edge has a better blocking and drainage effect on the water above. When β=60°, the angle between the second waterproof folded edge 203 and the second plate body 301 is small, but it can already better guide the water to flow away from the side. This design is suitable for environments with less rain or limited installation space. When β gradually increases to 125°, the second waterproof folded edge 203 becomes steeper, which can guide the water to flow away faster and reduce the time that the water stays on the side of the electrical box. This design is suitable for environments with more rain or requiring higher waterproof performance.

[0035] Furthermore, it also includes a cover plate 4 and a side plate 5, the second waterproof folded edge 203 at least partially abuts against the side wall of the cover plate 4, and the first waterproof folded edge 202 abuts against the outer wall surface or inner wall surface of the side plate 5. The second waterproof folded edge 203 at least partially abuts against the side wall of the cover plate 4 to form a tight waterproof interface, which can ensure that rainwater or other liquids cannot penetrate from the gap between the cover plate 4 and the electrical box. The first waterproof folded edge 202 abuts against the outer wall surface or inner wall surface of the side plate 5, which depends on the specific installation method and waterproof requirements. Whether it is the outer wall surface or the inner wall surface, it can effectively prevent moisture from penetrating into the electrical box from the side.

[0036] In some embodiments, a reinforcing rod is further included, and the reinforcing rod is disposed on the side of the second plate body 301. The reinforcing rod increases the rigidity and stability of the entire waterproof structure by increasing the support points on the side of the second plate body 301, which helps prevent structural deformation or damage caused by external pressure or vibration, and also reduces the risk of waterproof failure caused by structural deformation or damage.

[0037] In addition, the reinforcing rod is usually made of the same or similar material as the second plate 301 to ensure that it has good corrosion resistance and weather resistance, and these materials can withstand the influence of the external environment and maintain long-term stable performance. The size and number of reinforcing rods need to be determined according to specific application scenarios and requirements. Generally, larger waterproof structures may require larger or more reinforcing rods to provide sufficient support and reinforcement.

[0038] Furthermore, the first plate body 201 is provided with a third locking hole 204 corresponding to the second locking hole 102, the fastener passes through the third locking hole 204 and is locked in the second locking hole 102, the top surface of the column 1 is provided with a mounting plate 103, the first locking hole 101 is provided on the mounting plate 103, and the height of the first guide portion 302 is lower than the height of the mounting plate 103. Since the first plate body 201 and the column 1 are locked and fixed through the hole, there is a risk of water flowing down from the hole, so the first guide portion 302 needs to be provided below the mounting plate 103, and even if water flows down, it will flow out along the first guide portion 302 and will not enter the electrical box.

[0039] Alternatively, if Figure 6 As shown, an angle γ is formed between the first guide part 302 and the second plate body 301, and an angle δ is formed between the second guide part 303 and the second plate body 301, wherein γ=δ, 90°<γ≤150°. Setting the angles between the first guide part 302 and the second guide part 303 and the second plate body 301 to be equal can ensure that the water is subjected to the same guiding force when flowing through the two guide parts, so that it is more evenly dispersed and flows away. The angles γ and δ are greater than 90°, which means that the guide part is inclined downward, which helps the water to flow down naturally instead of accumulating on the side of the electrical box. The upper limit of the angle is set to 150° to ensure that the guide part has a sufficient slope to guide the water to flow away, while avoiding too large an angle causing structural instability or occupying too much space. Through this design, when the water flows through the first guide part 302 and the second guide part 303, it will be effectively guided to the bottom or side of the electrical box, thereby preventing the water from directly contacting the inside of the electrical box or accumulating on the side of the electrical box. The equality of the angles γ and δ and the appropriate angle range ensure that the water is guided evenly when flowing through the two guide parts, thereby improving the waterproof effect.
