[0036] The embodiments of the present utility model are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present utility model, and cannot be understood as limiting the present utility model.
[0037] In the description of the utility model, it is understood that the orientation description, such as the orientation or positional relationship of the indication such as upper and lower, is based on the orientation or positional relationship shown in the drawing, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as the limitation of the utility model.
[0038] In the description of the utility model, if the first and the second are described, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or the sequence of the indicated technical features.
[0039] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installing and connecting should be understood broadly, and the person skilled in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.
[0040] In the related art, the water pan of the box type heat pump equipment is usually arranged at the bottom of the box body, wherein the core functional components such as the electric control box, the fan and the compressor are installed on the upper side of the water pan. During the operation of the heat pump equipment, the surface of the functional components such as the electric control box and the fan will produce condensate water due to the influence of temperature difference, and the condensate water will naturally drip to the water pan below under the action of gravity, and finally be discharged through the pipeline.
[0041] Among them, the functional components and the panel usually have an installation gap, and when the heat pump equipment is running, frost phenomenon is easy to occur at the installation gap due to low temperature. Since the coverage range of the water pan is limited to the arrangement area of the functional components, the frost area is often located outside the effective coverage range of the water pan. When the frost melts, the defrosting water will directly drip on the outside of the water pan, and part of the defrosting water will accumulate at the bottom plate, causing corrosion to the components; another part of the defrosting water will overflow from the gap of the box body, causing the defrosting water to accumulate outside the heat pump equipment, thereby causing bacterial breeding, increasing the cleaning burden of the user, and seriously affecting the user experience.
[0042] In order to solve the above problems, some embodiments of the utility model provide a heat pump equipment 1000, which is specifically described with reference to Figures 1 to 9 The heat pump equipment 1000 is described.
[0043] Referring to Figure 1 and Figure 2As shown in the utility model embodiment, the heat pump equipment 1000 comprises a box body 100 and a functional component 200, wherein the box body 100 has an inner cavity for accommodating the functional component 200. The front side of the box body 100 is provided with a mounting port 110 and a panel 130, the mounting port 110 is communicated with the inner cavity, and the panel 130 is detachably mounted at the mounting port 110, based on which, the mounting port 110 can be opened or closed through the panel 130. In the embodiment, the box body 100 comprises a bottom disc 120, which is arranged at the bottom of the box body 100 and is provided with a water receiving groove 122 on the upper side for receiving condensed water and defrosting water.
[0044] With reference to Figure 1 As shown in the utility model embodiment, the functional component 200 is arranged on the upper side of the water receiving groove 122 and is connected at the mounting port 110 of the box body 100. It can be understood that the functional component 200 is directly above the water receiving groove 122, so that the condensed water generated on the surface of the functional component 200 can directly and naturally drip into the water receiving groove 122 below. It should be noted that there is an installation gap between the functional component 200 and the panel 130 on the front side, and frost phenomenon is prone to occur at the installation gap.
[0045] Considering that the installation gap between the functional component 200 and the panel 130 on the front side is not directly above the water receiving groove 122, so that the defrosting water cannot directly drip into the water receiving groove 122, in the utility model embodiment, the panel 130 is provided with a water blocking structure 300, and the water blocking structure 300 is arranged on the surface of the panel 130 facing the functional component 200. In the embodiment, the water blocking structure 300 is protruded from the rear end surface of the panel 130, and can guide the defrosting water to the water receiving groove 122.
[0046] Specifically, in combination with Figure 2 It can be understood that in the utility model embodiment, one end of the water blocking structure 300 is connected to the rear end surface of the panel 130, and the other end extends towards the rear side. On the projection plane perpendicular to the height direction of the box body 100, at least part of the projection of the water blocking structure 300 is located within the projection of the water receiving groove 122, in other words, at least part of the structure of the water blocking structure 300 is directly above the water receiving groove 122, that is, the water blocking structure 300 spans the installation gap between the functional component 200 and the panel 130, so that the defrosting water generated when the frost between the functional component 200 and the panel 130 melts can drip on the water blocking structure 300. Furthermore, the defrosting water dripping on the water blocking structure 300 can flow along the water blocking structure 300 and finally drip into the water receiving groove 122.
[0047] It can be understood that the heat pump equipment 1000 of the embodiment of the utility model reduces the possibility of defrosting water falling outside the water collecting groove 122 by setting the water blocking structure 300, not only can prevent the defrosting water from accumulating in the area outside the water collecting groove 122, thereby reducing the corrosion of the functional component 200 caused by the accumulation of defrosting water, but also can reduce the risk of the overflow of the frost water to the outside of the box 100, reduce the maintenance burden of the user to the equipment, and improve the use experience of the user.
[0048] Continuing to refer to Figure 1 As shown in the utility model embodiment, the functional component 200 includes the fan assembly 220 and the electric control box 210, and the fan assembly 220 and the electric control box 210 are arranged in the inner cavity along the left-right direction. Specifically, the electric control box 210 is used for electrically connecting the compressor, the fan assembly 220, the water pump and other components, and can also be connected with the external devices of the heat pump equipment 1000, for example, the water tank can be provided with a switch valve, the electric control box 210 can lead out the circuit and extend to the outside of the box 100, so that the circuit is connected with the switch valve, realizing the control of the switch valve. The fan assembly 220 is used for providing driving force for the airflow flow in the heat pump equipment 1000.
[0049] Specifically, referring to Figure 3 and Figure 4 As shown in the utility model embodiment, in order to guide the defrosting water between the electric control box 210 and the panel 130 and the defrosting water between the fan assembly 220 and the panel 130 respectively, the water blocking structure 300 includes a first water blocking piece 310 and a second water blocking piece 320, wherein the first water blocking piece 310 is arranged corresponding to the electric control box 210, and the second water blocking piece 320 is arranged corresponding to the fan assembly 220. In this embodiment, the fan assembly 220 and the electric control box 210 are arranged along the height direction of the box 100, and based on this, there is a gap between the electric control box 210 and the bottom plate 120, and the first water blocking piece 310 is arranged in the gap between the electric control box 210 and the bottom plate 120. There is also a gap between the fan assembly 220 and the bottom plate 120, and the second water blocking piece 320 is arranged in the gap between the fan assembly 220 and the bottom plate 120.
[0050] It can be understood that, in the utility model embodiment, referring to Figure 5 and Figure 6 As shown in the utility model embodiment, the first water blocking piece 310 not only can receive the defrosting water generated by the frost formed between the electric control box 210 and the panel 130 and guide the defrosting water to the water collecting groove 122, but also can receive the condensed water dripping from the surface of the electric control box 210, ensuring that the condensed water can also flow accurately into the water collecting groove 122; similarly, referring to Figure 7 and Figure 8As shown, the second water blocking member 320 is aimed at the defrosting water generated by the frost formed between the fan assembly 220 and the panel 130, and is used to guide the defrosting water to the water collecting groove 122, and can also receive the condensed water dripping from the surface of the fan assembly 220, so that the condensed water can also accurately flow into the water collecting groove 122.
[0051] With reference to Figure 1 As shown, in the embodiment of the utility model, the shell of the electric control box 210 is made of metal material, which is roughly a cuboid, the water collecting groove 122 is in the shape of a rectangle as a whole, and the electric control box 210 is located in the effective coverage range of the water collecting groove 122 as a whole. Specifically, on the projection plane perpendicular to the height direction of the cabinet 100, the projection of the electric control box 210 is located in the projection of the water collecting groove 122. In other words, neither the front end surface nor the side surface of the electric control box 210 exceeds the water collecting groove 122. In this embodiment, the condensed water formed on the surface of the electric control box 210 can directly drip into the water collecting groove 122 below, thereby reducing the possibility of the condensed water dripping outside the water collecting groove 122.
[0052] With reference to Figure 9 As shown, in the embodiment of the utility model, the fan assembly 220 comprises a duct structure 221 and a shell part 222 connected with each other, wherein the duct structure 221 is connected in the shell part 222, and a duct is formed in the duct structure 221. The shell part 222 is a sheet metal part, which provides protection and support for the duct structure 221, and the shell part 222 is connected with the cabinet 100 to realize the mounting and fixing of the fan assembly 220. On the projection plane perpendicular to the height direction of the cabinet 100, the projection of at least part of the shell part 222 is staggered with the projection of the water collecting groove 122, in other words, at least part of the structure of the shell part 222 exceeds the effective coverage range of the water collecting groove 122.
[0053] For this purpose, with reference to Figure 4 As shown, in the embodiment of the utility model, the outer periphery of the second water blocking member 320 is provided with a baffle 321, specifically, the left and right sides of the second water blocking member 320 are respectively provided with the baffle 321, the baffle 321 extends upward and protrudes from the upper end surface of the second water blocking member 320. The baffle 321 and the upper end surface of the second water blocking member 320 together define a water guide groove 322 for guiding, and the outlet of the water guide groove 322 is arranged towards the rear side. In this embodiment, the staggered projection is located in the projection of the water guide groove 322. In other words, the part of the shell part 222 exceeding the water collecting groove 122 is located directly above the water guide groove 322, and part of the condensed water generated on the surface of the shell part 222 will directly drip into the water collecting groove 122, and the other part will drip into the water guide groove 322, and then be guided to the water collecting groove 122 through the water guide groove 322, thereby avoiding the condensed water generated on the surface of the part of the shell part 222 exceeding the water collecting groove 122 from dripping to the outside of the water collecting groove 122.
[0054] With reference toFigure 4 As shown in the utility model embodiment, the water guide groove 322 comprises a first groove section 3221 and a second groove section 3222, the first groove section 3221 and the second groove section 3222 are in communication with each other, wherein the first groove section 3221 and the second groove section 3222 are arranged in sequence from front to back. The width of the first groove section 3221 along the left-right direction is greater than the width of the second groove section 3222 along the left-right direction, and the maximum width of the second groove section 3222 is equal to the minimum width of the first groove section 3221, and the opening of the water guide groove 322 is arranged at one end of the second groove section 3222 away from the first groove section 3221. It can be understood that the first groove section 3221 with relatively wider width can effectively receive defrosting water and condensed water falling from the upper side thereof, and the second groove section 3222 with relatively narrower width can improve the flow rate of water flow in the water guide groove 322, thereby reducing the risk of water accumulation in the water guide groove 322.
[0055] Specifically, in combination with Figure 3 and Figure 4 It can be understood that in the utility model embodiment, at least part of the upper end surface of the first water retaining part 310 and the upper end surface of the second water retaining part 320 is an inclined surface 330. Specifically, referring to Figure 3 As shown in the embodiment, the panel 130 and the functional component 200 are arranged in sequence from front to back, and based on this, the inclined surface 330 is arranged with downward offset from front to back. The upper end surface of the first water retaining part 310 comprises a horizontal surface section and an inclined surface section connected in sequence, wherein both the horizontal surface section and the inclined surface section can play a role in receiving defrosting water and condensed water, and the inclined surface section can make the water flow downward until falling into the water collecting groove 122.
[0056] Referring to Figure 3 As shown in the utility model embodiment, the upper end surface of the first groove section 3221 is an inclined surface 330, and the upper end surface of the second groove section 3222 can be an inclined surface or a horizontal surface. In the embodiment, the inclined surface 330 can receive defrosting water and condensed water on one hand, and on the other hand, can make the defrosting water and condensed water falling thereon flow to the second groove section 3222, and then fall into the water collecting groove 122.
[0057] It can be understood that in order to make the inclined surface 330 effectively drive the water in the water guide groove 322 to flow downward, in combination with Figure 6 and Figure 8 It can be understood that in the utility model embodiment, the inclined angle of the inclined surface 330 relative to the horizontal surface is a, which satisfies: a≥5°, and specifically, a can be 5°, 5.5°, 6°, 7°, 8°, etc., and the embodiment does not limit this. It can be understood that the inventors have known through experiments that when a<5°, the water in the water guide groove 322 will accumulate on the water guide groove 322 due to the influence of its own tension, causing the water flow on the water guide groove 322 to be unable to drain.
[0058] To this end, the present embodiment avoids water accumulation in the water guide groove 322 by reasonably limiting the range of a, thereby preventing water in the water guide groove 322 from overflowing from both sides of the water guide groove 322 and dripping outside the water collecting groove 122, and further ensuring that the inclined surface 330 can effectively guide the water flow to flow downward and finally drip into the water collecting groove 122.
[0059] Continuing to refer to Figure 6 and Figure 8 In the present embodiment, the height difference between the highest point and the lowest point of the inclined surface 330 along the height direction of the box body 100 is H, which satisfies: H≥3mm. Specifically, H can be 3mm, 4mm, 5mm, 6mm, etc., and the present embodiment does not limit this. Specifically, in the present embodiment, the inclined surface 330 is offset downward from front to back, so the front end of the inclined surface 330 is the highest point, and the rear end of the inclined surface 330 is the lowest point.
[0060] It can be understood that the inventor has learned through experiments that when H<3mm, the drainage performance of the water guide groove 322 is significantly reduced. To this end, the present embodiment reasonably limits the range of H, which not only ensures that the water in the water guide groove 322 can overcome the influence of surface tension and thus flow downward until it drips into the water collecting groove 122, but also avoids backflow of water flow in the water guide groove 322.
[0061] Referring to Figure 1 In the present embodiment, the functional component 200 further includes an evaporator 230 and a plate heat exchanger. The evaporator 230 is arranged at the middle part of the inner cavity and can separate the inner cavity to form an air inlet cavity 160 and an air outlet cavity 170. Correspondingly, the top cover 150 is provided with an air inlet 151 communicating with the air inlet cavity 160 and an air outlet 152 communicating with the air outlet cavity 170. The air inlet 151 and the air outlet 152 are respectively connected to the outdoor environment through pipelines. The outdoor cold air can enter the air inlet cavity 160 through the air inlet 151, then flow through the evaporator 230 for heat exchange, and then enter the air outlet cavity 170 and finally return to the outdoor environment through the air outlet 152. The plate heat exchanger and the compressor are arranged in the air inlet cavity 160, and the fan assembly 220 is arranged in the air outlet cavity 170.
[0062] In the present embodiment, the air duct structure 221 is made of foam material, so that the air duct structure 221 can separate the cold air in the air duct flowing into its interior from the panel 130. However, the cold air in the air inlet cavity 160 will directly contact the panel 130, causing the outer surface of the panel 130 to generate condensate. To this end, referring to Figure 2As shown in the embodiment, the surface of the panel 130 at the air inlet cavity 160 is covered with a heat preservation member 131. The heat preservation member 131 is made of foam material, so as to effectively prevent the cold air in the air inlet cavity 160 from contacting the panel 130.
[0063] With reference to the foregoing Figure 2 As shown in the embodiment, the first water retaining member 310 is arranged at the air inlet cavity 160, and the second water retaining member 320 is arranged at the air outlet cavity 170. In the embodiment, the second water retaining member 320 can be directly formed at the rear end surface of the panel 130. In one example, the surface of the panel 130 at the air inlet cavity 160 is covered with a heat preservation member, and the first water retaining member 310 is formed at the surface of the panel 130. The first water retaining member 310 can be arranged in a avoiding slot (not shown in the figure) of the heat preservation member, or be arranged in a spaced manner with the heat preservation member. In another example, the first water retaining member 310 can also be made of foam material, and be formed as an integral foam member with the heat preservation member 131.
[0064] With reference to the foregoing Figure 1 As shown in the embodiment, the bottom plate 120 is in a rectangular shape as a whole, and the upper end surface of the bottom plate 120 is protruded upward to form a surrounding edge 121, which is arranged along the circumferential direction of the bottom plate 120. In the embodiment, the surrounding edge 121 can be in a continuous and integral structure, or be in an intermittent and split structure, which is not limited in the embodiment. It can be understood that the surrounding edge 121 and the upper end surface of the bottom plate 120 jointly define a water collecting groove 122, so as to prevent the condensate water and defrosting water dropped to the bottom plate 120 from flowing to the surrounding.
[0065] The embodiment of the utility model also provides a hot water heating system, including the heat pump equipment 1000 of above-mentioned embodiment. Can understand, heat pump equipment 1000 can and gas wall-hanging stove, electric heater or water tank etc. external equipment connection, constitute hot water heating system, to provide domestic hot water and heating hot water for user.
