Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to a drainage component and a heat pump device. Background Technology

[0002] During the operation of a heat pump, the fan creates negative pressure at the base of the unit. This negative pressure causes water in the drain pipe connected to the base to flow back, resulting in a backflow phenomenon and making drainage difficult. Simultaneously, once the water in the drain pipe is drawn to a certain height, it will flow downwards again under gravity. This causes the water to oscillate back and forth within the drain pipe, generating noise and causing inconvenience to users. Utility Model Content

[0006] The drainage assembly according to the first aspect of this utility model has at least the following beneficial effects: the drainage pipe includes a bent section, and the opening of the bent portion of the bent section is arranged upwards, so that a certain amount of water can be stored in the bent section to form a liquid seal. Even if there is negative pressure in the chassis, the liquid seal can maintain its integrity, thereby effectively preventing outside air from being sucked into the drainage pipe and preventing water backflow. It can also prevent water from oscillating back and forth in the drainage pipe, effectively reducing drainage noise and improving the user experience. At the same time, the inlet and outlet sections of the drainage pipe are positioned by the first and second fixing members of the fixing base. On the one hand, this facilitates the installation of the drainage pipe through the fixing base; on the other hand, even if the drainage pipe is a flexible pipe, it can ensure that a part of the drainage pipe forms a bent section to achieve the anti-backflow function.

[0015] The heat pump device according to a second aspect embodiment of the present invention includes the drainage component of the first aspect embodiment of the present invention.

[0016] The heat pump device according to the second aspect of this utility model has at least the following beneficial effects: Because the heat pump device uses the aforementioned drainage assembly, the drain pipe includes a bent section with the opening of the bent portion facing upwards.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, connecting, assembling, and cooperating should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Heat pump equipment, such as heat pump air conditioners and heat pump water heaters, includes at least a chassis, a heat exchanger and a fan mounted on the chassis, and a drain pipe connected to the chassis. During operation, condensate from the heat exchanger drips onto the chassis and is then discharged through the drain pipe. Simultaneously, the high-speed operation of the fan creates negative pressure within the chassis, causing water to flow back into the drain pipe, resulting in backflow and drainage difficulties. Furthermore, once the water is drawn to a certain height in the drain pipe, it flows downwards again under gravity, creating a continuous cycle that causes significant noise and inconvenience to users.

[0034] Therefore, referring to Figures 1 to 6 As shown, the first aspect of this utility model provides a drainage component applied in a heat pump device. The drainage component is used to discharge condensate generated during the operation of the heat pump device to the outside of the heat pump device. The heat pump device here includes heat pump air conditioners, heat pump water heaters, and other similar devices.

[0035] Reference Figure 6 As shown, it can be understood that the heat pump equipment also includes at least the chassis assembly 300, heat exchanger, pipes, pump body, fan and other components. The chassis assembly 300 serves as a support platform for the installation and positioning of the heat exchanger, pipes, pump body, fan and other components of the heat pump equipment. At the same time, the chassis assembly 300 is also used to receive the condensate dripping from the heat exchanger during the operation of the heat pump equipment.

[0036] Reference Figure 6 As shown, it can be understood that the chassis assembly 300 is usually provided with a drain outlet. The drain assembly is connected to the bottom of the chassis assembly 300 and communicates with the drain outlet. Therefore, the drain assembly can discharge condensate to the outside of the heat pump equipment in a timely manner, so as to avoid affecting the normal operation of the heat pump equipment.

[0037] The following is a detailed description of the structural composition of the chassis assembly 300, in order to further understand the connection relationship between the drainage assembly and the chassis assembly 300.

[0038] Reference Figure 6 As shown, it can be understood that the chassis assembly 300 can be a metal disc or a combination of a metal disc and a plastic disc. In this embodiment, the chassis assembly 300 is configured as a combination of a metal disc and a plastic disc. Specifically, the chassis assembly 300 includes a first disc and a second disc. The first disc is a sheet metal part, i.e., a metal disc, and the second disc is a plastic part, i.e., a plastic disc. The second disc is disposed below the first disc and covers the bottom of the first disc. Typically, an insulation layer is also provided between the first disc and the second disc. The insulation layer is usually made of EPP foam material (i.e., polypropylene foam resin), which has good heat insulation properties.

[0039] The heat exchanger, pump body, fan, and other components are connected and fixed to the first plate. Since the first plate is made of sheet metal, its high structural strength ensures the installation stability of the heat exchanger, pump body, fan, and other components. By incorporating a second plate and an insulation layer, the thermal resistance between the inner side (facing the inside of the heat pump unit) and the outer side (facing the outside of the heat pump unit) of the chassis assembly 300 is significantly reduced due to the lower thermal conductivity of plastic parts compared to sheet metal parts, combined with the insulation layer. Therefore, in high-temperature and high-humidity external environments, the risk of condensation on the bottom wall of the chassis assembly 300 is effectively reduced. In low-temperature external environments, the risk of condensation freezing on the inner side of the chassis assembly 300 is also effectively reduced.

[0040] Understandably, the chassis assembly 300 typically includes a water collection chamber to collect condensate dripping from the heat exchanger. Specifically, the water collection chamber is located on the first plate, with its opening facing upwards, meaning it's situated on the side of the first plate away from the second plate. Since the first plate is a sheet metal part, a recess can be formed on it using a stamping process; this recess serves as the water collection chamber. It's also easy to understand that the chassis assembly 300 includes a drain outlet that penetrates the bottom wall of the water collection chamber and extends through the first plate, the insulation layer, and the second plate. The heat exchanger is located above the water collection chamber so that the condensate produced by the heat exchanger can accurately drip into the water collection chamber, allowing for the collection of the condensate and its discharge through the drain outlet to the outside of the heat pump equipment.

[0041] The following is a detailed description of the structural components of the drainage system.

[0042] Reference Figure 6 As shown, it can be understood that the drainage assembly is connected to the bottom of the second disc and communicates with the drain outlet. Specifically, the drainage assembly includes a drain pipe 100 and a mounting base 200.

[0043] Reference Figure 1 and Figure 6 As shown, the drain pipe 100 has an inlet 111 and an outlet 131 at both ends. The end of the drain pipe 100 with the inlet 111 is fixedly connected to the second plate and connects to the drain outlet. The end of the drain pipe 100 with the outlet 131 extends outwards from the heat pump unit and is typically connected to an external drain pipe to further discharge condensate to a designated location. Generally, the highest point of the drain pipe 100 is at the inlet 111. Therefore, the condensate in the water collection chamber can be discharged sequentially through the drain outlet and inlet 111 into the drain pipe 100, and then discharged to the outside of the heat pump unit through the outlet 131 of the drain pipe 100.

[0044] Reference Figures 1 to 3As shown, the drain pipe 100 includes an inlet section 110, a bend section 120, and an outlet section 130 connected in sequence. Specifically, the bend section 120 is generally U-shaped, V-shaped, or arc-shaped, and the opening of the bend in the bend section 120 faces upwards; that is, the bend in the bend section 120 is arranged with the curvature of the bend facing upwards. In other words, if the bend section 120 is U-shaped, the opening of the U-shaped structure faces upwards. Similarly, if the bend section 120 is V-shaped, the opening of the V-shaped structure also faces upwards; if the bend section 120 is arc-shaped, the opening of the arc-shaped structure also faces upwards. In this embodiment, the bend section 120 is U-shaped.

[0045] Reference Figures 1 to 3 As shown, it can be understood that one end of the inlet section 110 is connected to one end of the bend section 120, and the inlet section 110 is located above the bend section 120. The other end of the inlet section 110 is the inlet 111. One end of the outlet section 130 is connected to the other end of the bend section 120, and the outlet section 130 is located above the bend section 120. The other end of the outlet section 130 is the outlet 131. In this embodiment, the inlet section 110 extends upward, and the height of the inlet 111 is higher than the height of the highest point of the outlet section 130 to ensure normal drainage of the heat pump equipment.

[0046] Reference Figures 3 to 5 As shown, the mounting base 200 is used to install and fix the drain pipe 100. Specifically, the mounting base 200 is generally rectangular in shape and includes a first fixing member 210 and a second fixing member 220. The first fixing member 210 and the second fixing member 220 are respectively located in half of the rectangular structure, and the first fixing member 210 and the second fixing member 220 are arranged side by side in the horizontal direction. A first through groove 230 and a second through groove 240 are defined between the first fixing member 210 and the second fixing member 220, and the first through groove 230 and the second through groove 240 are arranged at intervals in the horizontal direction. The two ends of the first through groove 230 penetrate the lower end face and the upper end face of the mounting base 200, respectively, and one end of the second through groove 240 penetrates the lower end face of the mounting base 200, and the other end penetrates the upper end face or side wall of the mounting base 200.

[0047] Reference Figures 3 to 5As shown, it can be understood that the cross-sections of the first through groove 230 and the second through groove 240 are both circular. Specifically, the first through groove 230 includes a first half groove 231 and a second half groove 232, both of which have semi-circular cross-sections. The first half groove 231 is disposed on the wall surface of the first fixing member 210 facing the second fixing member 220, and the second half groove 232 is disposed on the wall surface of the second fixing member 220 facing the first fixing member 210. The positions of the first half groove 231 and the second half groove 232 are arranged correspondingly, and the combination of the first half groove 231 and the second half groove 232 forms the first through groove 230.

[0048] Reference Figures 3 to 5 As shown, it can be understood that, similarly, the second through groove 240 includes a third half groove 241 and a fourth half groove 242. The cross-sections of the third half groove 241 and the fourth half groove 242 are both semi-circular. The third half groove 241 is disposed on the wall surface of the first fixing member 210 facing the second fixing member 220, and the fourth half groove 242 is disposed on the wall surface of the second fixing member 220 facing the first fixing member 210. The positions of the third half groove 241 and the fourth half groove 242 are arranged correspondingly. The combination of the third half groove 241 and the fourth half groove 242 forms the second through groove 240.

[0049] Reference Figure 1 and Figure 5 As shown, it can be understood that the inlet section 110 passes through the first through groove 230, and the outlet section 130 passes through the second through groove 240. Specifically, the inlet section 110 passes through the first through groove 230 from bottom to top, and the outlet section 130 passes through the second through groove 240 from bottom to top. This ensures that the curved section is located below the fixed base 200. Generally, the outer diameter of the drain pipe 100 is equal to the inner diameter of the first through groove 230 and the inner diameter of the second through groove 240, or the outer diameter of the drain pipe 100 is slightly smaller than the inner diameter of the first through groove 230, and the outer diameter of the drain pipe 100 is also slightly smaller than the inner diameter of the second through groove 240.

[0050] Therefore, the drain pipe 100 can be fixed relative to the fixing seat 200, so that the drain pipe 100 can be installed on the wall or bracket through the fixing seat 200 to provide support for the drain pipe 100, meet the normal drainage requirements, and to a certain extent avoid the drawback of the drain pipe 100 moving and generating noise during the drainage process.

[0051] Reference Figure 1 and Figure 5As shown, it can be understood that in this embodiment, the drain pipe 100 is a flexible pipe that can bend freely under gravity. Therefore, when installing the drain pipe 100, the first fixing member 210 and the second fixing member 220 of the fixing base 200 can be assembled together to define the first through groove 230 and the second through groove 240 between the first fixing member 210 and the second fixing member 220. The inlet section 110 of the drain pipe 100 is inserted into the first through groove 230 from bottom to top, and the outlet section 130 of the drain pipe 100 is inserted into the second through groove 240 from bottom to top, so that the drain pipe 100 and the fixing base 200 are combined. At this time, the bent section 120 of the drain pipe 100 is located below the fixing base 200. Then, one end of the inlet 111 of the drain pipe 100 is connected to the chassis, and one end of the outlet 131 of the drain pipe 100 is connected to the external drain pipe.

[0052] It is easy to understand that the first through groove 230 of the fixing seat 200 positions the water inlet section 110 of the drain pipe 100, and the second through groove 240 of the fixing seat 200 positions the water outlet section 130 of the drain pipe 100, so that the bend section 120 of the drain pipe 100 can remain in a bent state.

[0053] Therefore, by setting a bend section 120 in the drain pipe 100, with the opening of the bend section 120 facing upwards, a certain amount of water can be stored in the bend section 120, a portion of the inlet section 110 near the bend section 120, and a portion of the outlet section 130 near the bend section 120, thus forming a liquid seal. Even if there is negative pressure within the chassis assembly 300, the liquid seal can maintain its integrity, effectively preventing outside air from being drawn into the drain pipe 100 and acting as an anti-backflow device. Simultaneously, it prevents water from oscillating back and forth within the drain pipe 100, effectively reducing drainage noise and improving the user experience.

[0054] In addition, the positioning function of the fixed seat 200 on the drain pipe 100 keeps the bend section 120 bent, thus achieving the function of preventing backflow.

[0055] In other embodiments, it is understood that the drain pipe 100 can also be a rigid pipe, such as a PVC pipe (polyvinyl chloride pipe), to ensure that the bend section 120 does not deform, thereby achieving the function of preventing backflow. When installing the drain pipe 100, the drain pipe 100 is first accommodated in the first half-groove 231 and the third half-groove 241 of the first fixing member 210, and then the second fixing member 220 is connected to the first fixing member 210, and the drain pipe 100 is accommodated in the second half-groove 232 and the fourth half-groove 242, so that the water inlet section 110 of the drain pipe 100 passes through the first through groove 230, the water outlet section 130 of the drain pipe 100 passes through the second through groove 240, and the drain pipe 100 is combined with the fixing seat 200 so that the drain pipe 100 can be installed through the fixing seat 200.

[0056] Reference Figure 2 As shown, it can be understood that the outer diameter of the drain pipe 100 is the same at all points. Let the outer diameter of the drain pipe 100 be d, and the vertical distance H between the center of the bend in the bend section 120 and the center of the outlet 131 of the outlet section 130. H can be easily understood as the height of the water column forming a liquid seal within the drain pipe 100. The outer diameter d of the drain pipe 100 and the vertical distance H between the center of the bend in the bend section 120 and the center of the outlet 131 of the outlet section 130 satisfy the following condition: d ≤ H ≤ 100 mm. That is, the vertical distance H between the center of the bend in the bend section 120 and the center of the outlet 131 of the outlet section 130 is greater than or equal to the outer diameter d of the drain pipe 100 to ensure that the water column stored within the drain pipe 100 can form a liquid seal. Setting H ≤ 100mm is easy to understand because 1mm of water column corresponds to 10Pa atmospheric pressure. Therefore, the maximum pressure that the water column in the drain pipe 100 can withstand is 1000Pa. Generally speaking, the negative pressure in the chassis assembly 300 is less than 1000Pa. Therefore, setting H ≤ 100mm can effectively ensure the liquid seal effect and prevent backflow.

[0057] Reference Figure 2 As shown, it can be understood that since the drain pipe 100 in this embodiment is a flexible pipe, the vertical distance H between the center of the bend of the bend section 120 and the center of the outlet 131 of the outlet section 130 can be adjusted by pulling the bend section 120 downward, that is, adjusting the height of the water column forming the liquid seal to meet different pressure requirements and prevent backflow.

[0058] Reference Figure 2 As shown, it can be understood that, generally speaking, the outer diameter d of the drain pipe 100 satisfies: 16mm ≤ d ≤ 58mm. This ensures that the outer diameter of the drain pipe 100 is large enough to meet the drainage requirements given a fixed wall thickness.

[0059] Reference Figure 2 and Figure 5 As shown, it can be understood that the second through slot 240 includes a first slot segment 243 and a second slot segment 244 that are interconnected. The first slot segment 243 and the second slot segment 244 form an angle θ between them, satisfying: 0°<θ≤90°. Figure 2The two dashed line segments forming an included angle θ represent the central axes of the first groove segment 243 and the second groove segment 244, respectively. In this example, the first groove segment 243 is arranged vertically, and the second groove segment 244 is arranged horizontally, meaning θ = 90°. Since the drain pipe 100 is a flexible pipe, by setting the second through groove 240 as the first groove segment 243 and the second groove segment 244 perpendicular to each other, after the drain pipe 100 passes through the second through groove 240, the pipe segment near the outlet 131 bends downward. At the same time, this increases the friction between the outlet section 130 of the drain pipe 100 and the groove wall of the second through groove 240, effectively improving the installation stability of the outlet section 130 of the drain pipe 100 within the second through groove 240, and maintaining the set structural shape of the bent pipe section 120 to prevent backflow.

[0060] In other embodiments, the included angle θ between the first groove segment 243 and the second groove segment 244 can also be 40°, 60° or 80°, that is, the second through groove 240 has an inverted V-shaped structure, which can further increase the friction between the water outlet section 130 of the drain pipe 100 and the groove wall of the second through groove 240, and improve the installation stability of the water outlet section 130 of the drain pipe 100 in the second through groove 240.

[0061] Reference Figure 3 and Figure 4 As shown, it can be understood that in the two opposing wall surfaces of the first fixing member 210 and the second fixing member 220, one wall surface is provided with a positioning recess 222, and the other wall surface is provided with a positioning protrusion 212, which is accommodated in the positioning recess 222. Specifically, the wall surface of the first fixing member 210 facing the second fixing member 220 has three positioning protrusions 212, which are spaced apart. One positioning protrusion 212 is located above the first fixing member 210, and the other two positioning protrusions 212 are located below the first fixing member 210. The line connecting the centers of the three positioning protrusions 212 forms an isosceles triangle. Correspondingly, the wall surface of the second fixing member 220 facing the first fixing member 210 has three positioning recesses 222, which are arranged in positions corresponding to the three positioning protrusions 212, and the three positioning protrusions 212 are correspondingly accommodated in the three positioning recesses 222. In this way, the first fixing member 210 and the second fixing member 220 are assembled and positioned so that the first half-groove 231 and the second half-groove 232 are accurately aligned, and the second half-groove 232 and the fourth half-groove 242 are accurately aligned, facilitating assembly. At the same time, since the line connecting the centers of the three positioning protrusions 212 forms an isosceles triangle, the first fixing member 210 and the second fixing member 220 are oriented in a certain direction during assembly, avoiding reverse assembly.

[0062] In other embodiments, the positions of the positioning protrusion 212 and the positioning recess 222 on the first fixing member 210 and the second fixing member 220 can be interchanged. The number of positioning protrusions 212 and positioning recesses 222 can also be two, four, five or more.

[0063] Reference Figure 2 and Figure 3 As shown, the drainage assembly also includes a connector for fixing the first fixing member 210 and the second fixing member 220 relative to each other. Specifically, the first fixing member 210 is provided with two first fixing grooves 213, located at the upper and lower ends of the first fixing member 210, respectively. Each first fixing groove 213 is a semi-annular groove. Correspondingly, the second fixing member 220 is provided with two second fixing grooves 223, the same number as the first fixing grooves 213. These two second fixing grooves 223 are located at the upper and lower ends of the second fixing member 220, respectively, and their positions correspond to the positions of the two first fixing grooves 213. Each second fixing groove 223 is also a semi-annular groove. Both ends of each second fixing groove 223 are connected to both ends of the first fixing groove 213, and each second fixing groove 223 is correspondingly connected to the two first fixing grooves 213. The first fixing groove 213 and the second fixing groove 223 combine to form an annular groove. That is, after the first fixing member 210 and the second fixing member 220 are combined, the upper and lower ends of the fixing base 200 are respectively provided with annular grooves. The connecting member can be a rubber band, iron wire, steel wire, pull rope, etc. The connecting member receives the annular groove to bind the first fixing member 210 and the second fixing member 220, thereby fixing the first fixing member 210 and the second fixing member 220 relatively, which helps to improve the structural stability of the fixing base 200, thereby ensuring the installation stability of the drain pipe 100 and the anti-backflow function.

[0064] Reference Figures 1 to 3 As shown, the first fixing member 210 is provided with two first fixing parts 211. These two first fixing parts 211 are located on the side of the first fixing member 210 opposite to the second fixing member 220, and are respectively located on opposite sides of the first fixing member 210 in the horizontal direction, at the upper and lower ends of the first fixing member 210. Each first fixing part 211 has a protruding structure. Both first fixing parts 211 are provided with first fixing holes 2111. Therefore, fasteners such as screws and rivets can be passed through the first fixing holes 2111 and connected to the wall or bracket to install the fixing base 200 and the drain pipe 100. The structure is simple, easy to install, and the installation is stable and reliable.

[0065] Reference Figures 1 to 3As shown, the second fixing member 220 is provided with two second fixing parts 221. These two second fixing parts 221 are located on the side of the second fixing member 220 opposite to the first fixing member 210, and are respectively located on opposite sides of the second fixing member 220 in the horizontal direction, at the upper and lower ends of the second fixing member 220. Each second fixing part 221 has a protruding structure. Both second fixing parts 221 are provided with second fixing holes 2211. Therefore, screws, rivets, or other fasteners can be used to pass through the second fixing holes 2211 and connect to the wall or bracket to install the fixing base 200 and the drain pipe 100. The structure is simple, easy to install, and the installation is stable and reliable.

[0066] Reference Figure 2 As shown, it can be understood that the central axis of the second fixing hole 2211 is parallel to the central axis of the first fixing hole 2111, and the first fixing part 211 and the second fixing part 221 are staggered along the direction of the central axis of the first fixing hole 2111. This avoids structural interference between the first fixing part 211 and the second fixing part 221, which would affect the installation of the fixing base 200. Therefore, the fixing base 200 and the drain pipe 100 can be installed on the wall or bracket through the first fixing part 211 or the second fixing part 221, so that the drainage direction of the drain pipe 100 can be adjusted according to the position of the external drain pipe, which has good applicability.
