Description

Technical Field

[0001] The utility model relates to the technical field of heat pump water heaters, in particular to an internal unit of a heat pump water heater and a heat pump water heater. Background Art

[0002] The working process of a heat pump water heater is roughly as follows: the compressor compresses the returning low-pressure refrigerant and turns it into high-temperature and high-pressure gas for discharge; the high-temperature and high-pressure refrigerant gas flows through the copper tube, transferring heat to the water tank, while the cooled refrigerant becomes liquid under pressure and enters the evaporator; in the evaporator, the liquid refrigerant quickly evaporates into gas and absorbs a large amount of heat; at the same time, the fan causes a large amount of air to flow over the surface of the evaporator, and the energy in the air is absorbed by the evaporator and releases cold air; then, the refrigerant that has absorbed a certain amount of energy flows back to the compressor and enters the next cycle.

[0003] Compared with traditional water heaters, heat pump water heaters have a significantly different heating method. It uses air, water and / or solar energy as a low-temperature heat source, and uses electricity as a power to absorb heat from the low-temperature side to heat domestic water. This heating method is not only fast, but also has stable temperature, less scale, and occupies a small area. In general, heat pump water heaters have been increasingly widely used in modern life due to their high efficiency, energy saving, and environmental protection.

[0053] The core of the utility model is to provide an internal unit of a heat pump water heater to improve assembly efficiency;

[0054] Another core of the utility model is to provide a heat pump water heater having the above-mentioned heat pump water heater internal unit.

[0055] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0056] like Figure 1-Figure 3As shown, the embodiment of the utility model discloses a heat pump water heater internal unit, which includes a detachably connected bottom module 100 and a top module 200. Specifically, the bottom module 100 and the top module 200 can be fixed by fasteners.

[0057] The bottom module 100 includes a bottom support frame, a heat-insulating inner liner 105 disposed in the bottom support frame, and an inner liner pipeline assembly connected to the heat-insulating inner liner 105. The heat-insulating inner liner 105 is used to store heated hot water. It should be noted that in order to improve the heat-insulating effect of the heat-insulating inner liner 105, a heat-insulating layer is disposed on the outer side of the heat-insulating inner liner 105. In order to improve the strength of the heat-insulating layer, a convex reinforcing rib 111 can be integrally formed on the outer side of the heat-insulating layer to improve the rigidity of the heat-insulating layer and prevent the heat-insulating layer from deforming.

[0058] The top module 200 includes a top module support frame and a system pipeline assembly 206 disposed in the top module support frame. The top module support frame is detachably connected to the upper part of the bottom support frame, and the system pipeline assembly 206 is correspondingly connected to the inner tank pipeline assembly. The connection between the external device and the thermal insulation inner tank 105 is achieved under the action of the system pipeline assembly 206. It should be noted that the pipeline system of the heat pump water heater internal unit can be the same as the prior art. The focus of this article is not on the connection relationship between the system pipeline assembly 206 and the external device and the thermal insulation inner tank 105, but on the change in the installation position of each component of the heat pump water heater internal unit. The connection relationship of the system pipeline assembly 206 will not be repeated here.

[0059] The heat pump water heater internal unit provided by the utility model divides the integrated internal unit into a detachable bottom module 100 and a top module 200, and sets the heavier heat preservation inner tank 105 on the bottom module 100. The system pipeline assembly 206 is set on the top module 200 to facilitate pipeline connection with external equipment. When assembling the heat pump water heater internal unit provided by the utility model, the bottom module 100 and the top module 200 can be assembled separately, and then the assembled top module 200 and the bottom module 100 are assembled, thereby improving assembly efficiency.

[0060] In this embodiment, a water receiving tray 106 is provided on the top of the bottom module 100, one end of the inner tank pipe assembly extends out of the water receiving tray 106, and the end extending out of the water receiving tray 106 is provided with a first pipe joint 110. The first pipe joint 110 can be sealed and fixed on the bottom wall of the water receiving tray 106. The system pipe assembly 206 is provided with a second pipe joint correspondingly connected to the first pipe joint 110 at one end near the bottom of the bottom support frame. When the bottom module 100 is installed on the top module 200, the first pipe joint 110 and the second pipe joint should be connected correspondingly.

[0061] like Figure 4-Figure 7As shown, the system piping assembly 206 is provided with a third pipe joint 212 for connecting with external equipment at one end near the top of the bottom support frame, and a top plate 205 is provided on the top of the top module support frame. The third pipe joint 212 extends outward from the outside of the top plate 205 to facilitate connection with external equipment.

[0062] like Figure 4 As shown, in a specific embodiment of the utility model, the heat pump water heater indoor unit may further include a pipe fixing assembly arranged on the top of the top module support frame, one end of the system pipe assembly 206 provided with the third pipe joint 212 is constrained by the pipe fixing assembly, and the pipe fixing assembly is located at the lower side of the top plate 205. Under the action of the pipe fixing assembly, each pipe of the system pipe assembly 206 can be constrained on one side of the top module 200 to facilitate the arrangement of external pipes. For example, in the solution disclosed in this embodiment, each pipe of the system pipe assembly 206 is constrained on the back side of the top module 200 to facilitate the hiding of external pipes and improve the aesthetics.

[0063] Furthermore, the pipeline fixing assembly may include a pipeline support 208 and a pipeline pressure plate 209. Among them, the pipeline support 208 is arranged on the top of the top module support frame, and the pipeline support 208 has a pipeline slot with an opening on one side, and each pipeline of the system pipeline assembly 206 is correspondingly inserted into the pipeline slot through the opening. The side wall of the pipeline slot can limit the left and right movement of the pipeline. Since the pipeline slot has an opening, each pipeline can still slide out of the corresponding pipeline slot through the opening. Based on this, the pipeline pressure plate 209 is added, and the pipeline pressure plate 209 is fixed to the side of the pipeline support 208 with an opening to close the opening of the pipeline slot. The pipeline pressure plate 209 can be detachably fixed to the pipeline support 208 by fasteners.

[0064] In addition, the pipeline support 208 has different positions for arranging pipelines, that is, not all pipelines are arranged in a straight line. Therefore, in order to avoid the pipeline groove being too deep and unable to form a limiting effect in the depth direction, it is necessary to ensure that the depth of the pipeline groove should be close to the diameter of the pipeline, that is, slightly larger than the diameter of the pipeline. Combined with the fixed position of the pipeline, the side of the pipeline support 208 with an opening is designed as a stepped surface, and the shape of the pipeline pressure plate 209 is correspondingly designed to be the same as the stepped surface to ensure a perfect fit. Moreover, the stepped surface of the pipeline support 208 also has a limiting function on the pipeline pressure plate 209, ensuring that the fastener holes on the two can be aligned when fitting or not, which is convenient for fixing the fasteners.

[0065] Furthermore, a buffer block 210 is embedded between the pipeline of the system pipeline assembly 206 and the inner wall of the pipeline slot. In this embodiment, by adding the buffer block 210, it is possible to save development costs while effectively avoiding pipeline vibration caused by power components such as water pumps, and transmitting the vibration to the box through the pipeline to cause noise.

[0066] like Figure 2 As shown, in a specific embodiment of the present invention, the bottom support frame includes a bottom plate 101 , a rear support plate 102 , a left lower vertical beam 103 , a right lower vertical beam 104 , a first base 108 and a second base 109 .

[0067] The bottom plate 101 is used to support the thermal insulation liner 105 , and the rear support plate 102 is connected to one side of the bottom plate 101 . Usually, the rear support plate 102 is arranged on the side opposite to the panel.

[0068] The left lower vertical beam 103 and the right lower vertical beam 104 are connected to the other side of the bottom plate 101, that is, the left lower vertical beam 103 and the right lower vertical beam 104 are connected to one side of the panel, and the left lower vertical beam 103 and the right lower vertical beam 104 are parallel to the rear support plate 102 and arranged at equal intervals, and the distance between the left lower vertical beam 103 and the right lower vertical beam 104 forms the width of the heat pump water heater. The rear support plate 102 occupies two corners of the bottom plate 101, and the left lower vertical beam 103 and the right lower vertical beam 104 occupy the other two corners of the bottom plate 101 respectively.

[0069] The first foot 108 and the second foot 109 are arranged at the four corners of the bottom plate 101, the first foot 108 is arranged at the corresponding positions on both sides of the bottom of the rear support plate 102, and the second foot 109 is arranged at the corresponding positions of the bottom of the left lower vertical beam 103 and the right lower vertical beam 104. In this embodiment, by adding the first foot 108 and the second foot 109 at the four corners of the bottom plate 101, the support area of ​​the heat pump water heater can be increased and the stability can be improved.

[0070] The first foot 108 and the second foot 109 both extend to the outside of the bottom support frame, and the extension directions of the first foot 108 and the second foot 109 are not parallel. Figure 2 As shown, the second foot 109 extends in a direction perpendicular to the rear support plate 102, and the first foot 108 extends in a direction parallel to the rear support plate 102. In this embodiment, the first foot 108 and the second foot 109 are distributed asymmetrically front to back, which can make the force on the bottom plate 101 and the packaging base more uniform, and effectively prevent the heat pump water heater from tilting front to back and left to right.

[0071] like Figure 3As shown, the rear support plate 102 is provided with bending reinforcement parts 1021 on both sides along the width direction, and the bending reinforcement parts 1021 form a wiring tube channel extending along the height direction, and the wiring tube channel is used to arrange pipelines and cables. The rear support plate 102 can form the bending reinforcement part 1021 through a bending process, which improves the overall strength of the rear support plate 102 compared with not providing the bending reinforcement part 1021. The side of the bending reinforcement part 1021 facing away from the left lower vertical beam 103 and the right lower vertical beam 104 forms a wiring tube channel with an opening.

[0072] In this embodiment, the opening of the wiring tube channel is set on the rear side of the heat pump water heater internal unit, which can facilitate the arrangement of external pipelines in the wiring tube channel. At the same time, the corresponding cables can also be arranged to hide the pipelines and cables and achieve an aesthetic effect. At the same time, the side walls of the wiring tube channel also have a protective effect on the pipelines and cables, preventing external objects from colliding with the pipelines and cables and affecting the service life of the pipelines and cables.

[0073] It should be noted that at least two side edges and the top edge of the rear support plate 102 have a flange structure 1022, which can limit the left side plate 301, the right side plate 302 and the top plate 205 of the heat pump water heater indoor unit to facilitate the installation of the left side plate 301, the right side plate 302 and the top plate 205.

[0074] like Figure 3 As shown, the rear support plate 102 extends to the top module 200, so that the rear support plate 102 can facilitate the installation of the top module 200. When installing the top module 200, it is only necessary to fit the rear side of the top module 200 to the rear support plate 102 and then lock the fasteners at the corresponding positions.

[0075] like Figure 2 As shown, the top module support frame may include a rear vertical beam 211, a left upper vertical beam 201, and a right upper vertical beam 202. There are two rear vertical beams 211, which are respectively attached to the two bending reinforcement parts 1021. During installation, the top module support frame can be positioned above the bottom module 100 by attaching the two rear vertical beams 211 to the two bending reinforcement parts 1021, and the opening side of the wiring tube channel is located on the side facing away from the rear vertical beams 211.

[0076] The upper left vertical beam 201 and the upper right vertical beam 202 form four edges of a quadrangular prism structure with two rear vertical beams 211. The upper left vertical beam 201 and the upper right vertical beam 202 can be fixed above the lower left vertical beam 103 and the lower right vertical beam 104, respectively. A reinforcing cross beam 203 can be arranged between the rear vertical beam 211 and the upper right vertical beam 202, and of course, a reinforcing cross beam 203 can also be arranged between the rear vertical beam 211 and the lower right vertical beam 104, so as to increase the strength of the top module support frame.

[0077] It should be noted that, in addition to the system pipeline assembly 206, the top module support frame may also be provided with an electric heater 207. The electric heater 207 may pump water in the thermal insulation liner 105 into the electric heater 207 through a water pump, and then pump the water back to the thermal insulation liner 105 after being heated by the electric heater 207, so as to achieve auxiliary heating. The electric heater 207 may be fixed in the top module support frame through the electric heating bracket 204 to ensure the stability of the electric heater 207 in the top module support frame.

[0078] like Figure 2 and Figure 6 As shown, the indoor unit of the heat pump water heater disclosed in the embodiment of the utility model may also include an outer panel assembly arranged on the outside of the bottom module 100 and the top module 200, and the outer panel assembly may include a left panel 301, a right panel 302, a front panel 303 and a front decorative panel 305.

[0079] The left side plate 301 and the right side plate 302 are symmetrically arranged on both sides of the bottom module 100 and the top module 200, and both the left side plate 301 and the right side plate 302 extend from the bottom module 100 to the top module 200, the left side plate 301 covers one side of the left lower vertical beam 103 and the rear support plate 102, and the right side plate 302 covers the other side of the right lower vertical beam 104 and the rear support plate 102. The left side plate 301 and the right side plate 302 can be detachably arranged on both sides of the bottom module 100 and the top module 200 by fasteners.

[0080] The front panel 303 is arranged on the bottom module 100 and covers the lower left vertical beam 103 and the lower right vertical beam 104. The front trim 305 is arranged on the top module 200 and covers the upper left vertical beam 201 and the upper right vertical beam 202. The front trim 305 is provided with a display area. In this embodiment, the front panel 303 and the front trim 305 are divided into two parts. The purpose is to set the display module on the top module 200. The display module has a corresponding circuit part, which is easy to be damaged or malfunction, and the maintenance frequency is high. Therefore, the top module 200 is provided with an independently detachable front trim 305, so that the display module can be repaired by only removing the front trim 305 without removing the front panel 303.

[0081] In order to achieve an aesthetic effect, a decorative strip 304 can be added between the front panel 303 and the front trim panel 305 to achieve a layered effect, so that the heat pump water heater indoor unit has more panel elements on the side facing the user (i.e., the front side of the heat pump water heater indoor unit), thereby improving the aesthetic effect.

[0082] like Figure 2As shown, the electric control box 400 of the heat pump water heater indoor unit is arranged at a height corresponding to the rear support plate 102 and the top module 200, and is located on the side of the rear support plate 102 facing away from the top module 200. The left lower vertical beam 103 and the right lower vertical beam 104 are connected by a support beam 107 at one end close to the top module 200, and the support beam 107 can be used to support the front panel 303 and fix the wiring. Furthermore, each sheet metal structural part of the heat pump water heater indoor unit is made by CNC processing technology to save development costs.
