Description

Technical Field

[0001] This utility model relates to the field of heat pump water heater technology, and in particular to an optimized structure of a multi-electric control box and an air source heat pump water heater. Background Technology

[0002] With the widespread application of heat pump technology, integrated air source heat pump water heaters have secured a significant market position due to their high efficiency and energy-saving characteristics. However, in existing designs, the electrical control box is typically installed at the top of the machine, resulting in a large volume and fixed layout. This layout encroaches on the air cavity space, leading to reduced airflow and turbulent airflow, thus affecting heat pump efficiency. For example, patent CN214665198U optimizes the air duct through a guide cavity and a square fan, but it does not solve the problem of the electrical control box layout obstructing the air cavity; patent CN220871133U is a single electrical control box design, which still suffers from the defect of high local wind resistance. Therefore, for heat pump water heaters with multiple electrical control boxes, there is an urgent need for a technical solution that can optimize the layout of the electrical control boxes while actively guiding airflow and reducing wind resistance to minimize the impact on airflow. Utility Model Content

[0003] The purpose of this utility model is to provide an optimized structure for multiple electrical control boxes and an air source heat pump water heater, so as to solve the technical problem mentioned in the background art that the layout of multiple electrical control boxes is unreasonable. Currently, some are installed on the upper part of the machine, which occupies the air cavity space and obstructs the airflow into the heat pump water heater.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An optimized structure for a multi-control box is provided in the upper assembly of an air source heat pump water heater. The upper assembly includes a base and an evaporator erected on the base.

[0006] An irregularly shaped electrical control box is located on the top side of the evaporator. The cross-section of the irregularly shaped electrical control box is a right-angled trapezoidal structure. It is formed by an upper base plate, a lower base plate, a sloping waist plate, a right-angled waist plate, and a side sealing plate. The sloping waist plate is parallel to the panel located on the top of the evaporator. The upper base plate is sloping downward relative to the sloping waist plate and forms a downwardly extending eave with the right-angled waist plate in space. The lower base plate, which is arranged parallel to the upper base plate, is connected to the right-angled waist plate on one side and to the sloping waist plate on the other side. The lower base plate forms an angle with the evaporator in the side view direction.

[0007] At least one second electrical control box is vertically mounted on the base, forming an angle with the evaporator in a top view; the irregularly shaped electrical control box and the second electrical control box form a semi-enclosed or fully enclosed air cavity in space.

[0008] As a preferred technical solution of this utility model, the bottom plate has a locking point extending outward from the center of one end and bending downward. The panel has several positioning points extending from one end. A lock hole matching the locking point is provided next to the positioning point located in the center. The sloping waist plate that is connected to the panel has an overlapping point extending from one end that matches the positioning point. After the positioning points of the panel and the overlapping points of the sloping waist plate are connected and installed, several heat dissipation channels are formed.

[0009] More preferably, the lower base plate has an upwardly bent abutting end on the side away from the steam evaporator, which abuts against the right-angle waist plate; the two ends of the lower base plate facing the evaporator have wing ends facing the evaporator, which are fixedly connected to the evaporator through the wing ends; the side sealing plate has an extension on the side near the evaporator for overlapping and fixing with the wing ends.

[0011] More preferably, the auxiliary support includes a support body and a bending portion. The outer periphery of the support body has a guide groove that matches the contour nozzle. The support body has a vertical wire through hole and a bending portion perpendicular to the support body on one side of its bottom end. The bending portion abuts against the lower base plate.

[0012] This utility model of an air source heat pump water heater also includes a lower assembly, which is integrated with the upper assembly and includes the optimized structure of the multi-electric control box, located on the front side of the evaporator. The upper assembly also includes a top cover and a compressor. The top cover has an air inlet and an air outlet circumferentially opened, and ventilation covers are respectively installed on the front and rear sides of the evaporator.

[0013] Preferably, it also includes a heat exchange assembly, which includes a fan and a fan shroud. One end of the fan shroud is connected to the rear side of the evaporator, the fan is placed inside the fan shroud, and the other end of the fan shroud faces the air outlet.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-7 As shown, an optimized structure with multiple electrical control boxes is provided in the upper assembly 100 of an air source heat pump water heater. The upper assembly 100 includes a base 3 and an evaporator 4 erected on the base 3.

[0026] An irregularly shaped electrical control box 1 is located on the top side of the evaporator 4. The cross-section of the irregularly shaped electrical control box 1 is a right-angled trapezoidal structure. It is formed by an upper base plate 12, a lower base plate 14, a sloping waist plate 11, a right-angled waist plate 13, and a side sealing plate 15. The sloping waist plate 11 is parallel to the panel 40 located on the top of the evaporator 4. The upper base plate 12 is obliquely downward relative to the sloping waist plate 11 and forms an obliquely downward extending eave with the right-angled waist plate 13 in space. The lower base plate 14, which is arranged parallel to the upper base plate 12, is connected to the right-angled waist plate 13 on one side and to the sloping waist plate 11 on the other side. The lower base plate 14 forms an angle with the evaporator 4 in the side view direction.

[0027] At least one second electrical control box 2 is vertically mounted on the base 3, forming an angle with the evaporator 4 in the top view direction; the irregularly shaped electrical control box 1 and the second electrical control box 2 form a semi-enclosed or fully enclosed air cavity in space.

[0028] The irregularly shaped electrical control box 1 installed on the top side of the evaporator 4 has a right-angled trapezoidal structure and placement method, which forms an eaves-like airflow guide structure to optimize the airflow path and reduce wind resistance. The eaves and the base 3, together with the second electrical control box 2 set on one or both sides of the evaporator 4, form an upper air guide plate to guide the airflow along a preset path.

[0029] In this embodiment, the multi-control box optimized structure includes an irregularly shaped control box 1 located on the top side of the evaporator 4 and a second control box 2 vertically mounted on the base 3. The two form a semi-enclosed air cavity in space. If two second control boxes 2 are symmetrically arranged, a fully enclosed air cavity is formed in space.

[0030] To improve the stability of the irregularly shaped electrical control box 1, such as Figure 2 , Figure 5 As shown, the lower base plate 14 has a locking point 140 extending outward and bending downward from one end of its center. The panel 40 has several positioning points extending from one end, with a locking hole matching the locking point 140 located next to the central positioning point. The inclined waist plate 11, which connects to the panel 40, has an overlapping point 110 matching the positioning points. After the positioning points of the panel 40 and the overlapping points 110 of the inclined waist plate 11 are connected and installed, several heat dissipation channels 41 are formed. Since the electrical control box generates heat, the heat dissipation channels 41 are provided to improve the overall heat exchange efficiency of the upper assembly 100.

[0031] More preferably, such as Figure 3 , Figure 4As shown, the lower base plate 14 has an upwardly bent abutment end 142 on the side away from the steam generator, which abuts against the right-angle waist plate 13; the two ends of the lower base plate 14 facing the evaporator 4 have wing ends 141 facing the evaporator 4, which are fixedly connected to the evaporator 4 through the wing ends 141; the side sealing plate 15 has an extension 151 on the side near the evaporator 4, which is used to overlap and fix with the wing ends 141.

[0032] The preferred embodiments of this utility model are as follows: Figure 4 As shown, the side sealing plate 15 has a contoured nozzle 150 extending upwards from the bottom edge. The side sealing plate 15 is inserted into the contoured nozzle 150 via an auxiliary support member 16, which simultaneously supports the bottom plate 14.

[0033] Preferably, such as Figure 6 As shown, the auxiliary support 16 includes a support body 160 and a bending portion 163. The outer periphery of the support body 160 has a guide groove 162 that matches the contour nozzle 150. A wire through-hole 161 is vertically arranged inside the support body 160, and a bending portion 163, perpendicular to the support body 160, is provided on one side of its bottom end. The bending portion 163 abuts against the lower base plate 14. The auxiliary support 16, through the wire through-hole 161, ensures neat and aesthetically pleasing wiring, while the bending portion 163 abuts against the lower base plate 14, improving the connection stability between the lower base plate 14 and the side sealing plate 15.

[0034] like Figure 7 As shown, the air source heat pump water heater of this utility model also includes a lower assembly 200, which is integrated with the upper assembly 100 and includes the optimized structure of the multi-electric control box, which is located on the front side of the evaporator 4. The upper assembly 100 also includes a top cover 103 and a compressor. The top cover 103 has an air inlet 101 and an air outlet 102 circumferentially opened, and ventilation covers are respectively installed on the front and rear sides of the evaporator 4.

[0035] Preferably, it also includes a heat exchange assembly, which includes a fan and a fan shroud 5. One end of the fan shroud 5 is connected to the rear side of the evaporator 4, the fan is placed inside the fan shroud 5, and the other end of the fan shroud 5 faces the air outlet 102.

[0036] In this embodiment of the air source heat pump water heater, air enters through the air inlet 101 and flows from front to back. The rear-mounted fan creates negative pressure, drawing air through the air inlet 101 into the air cavity and exhausting it through the air outlet 102 connected to the fan shroud. Simultaneously, the heat generated by the irregularly shaped electrical control box 1 enters the air cavity through the heat dissipation channel 41 and is then exhausted. The electrical control box features an optimized structural design; the top-mounted electrical control box frees up space in the traditional upper air cavity, increasing the air intake cross-sectional area; the eaves, base 3, and side electrical control boxes work together to guide airflow, reducing airflow turbulence and lowering local wind resistance.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
