Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to a side-discharge heat pump water heater casing and a side-discharge heat pump water heater. Background Technology

[0002] To facilitate the design of air inlets and outlets and enable air convection, the outer casing of existing side-discharge heat pump water heaters is generally designed as a single piece. When the side-discharge heat pump water heater needs maintenance, the entire casing needs to be disassembled upwards. In some confined spaces, this makes disassembly of the single-piece casing inconvenient.

[0003] To address the above issues, some casings employ a split structure, with the front and rear shells being detachably connected for easier maintenance. However, in split-structure casings, placing the air inlet and outlet at the seam increases airflow resistance. Therefore, to avoid the seam, the air inlet is placed on the front shell and the outlet on the rear shell, resulting in an off-center position. This design prevents convection between the air inlet and outlet, reducing the energy efficiency of the side-discharge heat pump water heater. Utility Model Content

[0039] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] like Figures 1-7 As shown, this utility model embodiment provides a side-discharge heat pump water heater shell, including a shell body 1, which includes a front shell 11 and a rear shell 12. The front shell 11 is provided with a front air outlet 111 and a front air inlet 112, and the rear shell 12 is provided with a rear air outlet 121 and a rear air inlet 122. A first vertical rib 13 is provided on one side of the front shell 11 at the front air outlet 111 and on one side of the rear shell 12 at the rear air outlet 121. A second vertical rib 14 is provided on one side of the front shell 11 at the front air inlet 112 and on one side of the rear shell 12 at the rear air inlet 122.

[0041] Two first vertical stiffeners 13 are joined together so that the front air outlet 111 and the rear air outlet 121 form the air outlet of the shell body 1. Two second vertical stiffeners 14 are joined together so that the front air inlet 112 and the rear air inlet 122 form the air inlet of the shell body 1. This structure sets the joint of the front shell 11 and the rear shell 12 at the air outlet and the air inlet, so that the air inlet and the air outlet can form air convection, which can improve energy efficiency.

[0042] Furthermore, in order to reduce the air outlet resistance, the two first vertical stiffeners 13 are provided with rounded corners 131 at one end inside the shell body 1. That is, the corners of the two first vertical stiffeners 13 that are far apart from each other are provided with rounded corners 131. This structural design can reduce the air outlet resistance.

[0043] The outer casing of this side-discharge heat pump water heater is designed as a split structure, which facilitates later maintenance. The air outlet is located at the joint of the front casing 11 and the rear casing 12 on one side. The two first vertical ribs 13 are provided with rounded corners 131 at one end inside the casing 1, which can effectively reduce the air outlet resistance. In addition, the air inlet is located at the joint of the front casing 11 and the rear casing 12 on the other side, so that the air inlet and the air outlet can form air convection, which can effectively improve energy efficiency.

[0044] In order to minimize the resistance of the first vertical stiffener plate 13 to the airflow, the thickness of the first vertical stiffener plate 13 is controlled between 3mm and 5mm, and the total thickness of the two first vertical stiffener plates 13 after being joined is controlled between 6mm and 10mm. That is, while ensuring the strength of the first vertical stiffener plate 13, the airflow resistance is minimized.

[0045] In this embodiment, the thickness of the first vertical stiffener plate 13 is set to 4 mm.

[0046] Optionally, such as Figures 4-7As shown, one of the two first vertical ribs 13 is provided with a first guide pin 132, and the other is provided with a first pin hole. When the two first vertical ribs 13 are mated together, the first guide pin 132 is inserted into the first insertion hole 133. One of the two second vertical ribs 14 is provided with a second guide pin, and the other is provided with a second pin hole. When the two second vertical ribs 14 are mated together, the second guide pin is inserted into the second pin hole. The shell body 1 also includes a first screw 15 and a second screw 17. One of the two first vertical ribs 13 is also provided with a first through hole, and the other is also provided with a first threaded hole 134. The first screw 15 passes through the first through hole and is screwed into the first threaded hole 134 to connect the two first vertical ribs 13. One of the two second vertical ribs 14 is also provided with a second through hole, and the other is also provided with a second threaded hole. The second screw 17 passes through the second through hole and is screwed into the second threaded hole to connect the two second vertical ribs 14. The above structure enables the interconnection of the front shell 11 and the rear shell 12. Specifically, when the front shell 11 and the rear shell 12 are mated, the first guide pin 132 and the first pin hole interlock to guide the two first vertical stiffener plates 13, and then the first screw 15 is used for connection. This improves the installation efficiency of the two first vertical stiffener plates 13, and the cooperation between the first guide pin 132 and the first screw 15 ensures a stable connection between the two first vertical stiffener plates 13. Similarly, the second guide pin and the second pin hole interlock to guide the two second vertical stiffener plates 14, and then the second screw 17 is used for connection. This improves the installation efficiency of the two second vertical stiffener plates 14, and the cooperation between the second guide pin and the second screw 17 ensures a stable connection between the two second vertical stiffener plates 14. This structure improves the installation efficiency and connection stability of the front shell 11 and the rear shell 12; moreover, the first guide pin 132 does not affect the air outlet, and the second guide pin does not affect the air inlet.

[0047] Optionally, the number of first guide pins 132 and first insertion holes 133 is set to multiple and correspond one-to-one. By setting multiple first guide pins 132, the connection firmness of the two first vertical stiffeners 13 can be further improved; and when the two first vertical stiffeners 13 are connected to each other, since the first guide pins 132 are located between the two first vertical stiffeners 13, the first guide pins 132 do not have any impact on the air outlet. In this embodiment, five first guide pins 132 and five first insertion holes 133 are provided.

[0048] Optionally, multiple second guide pins and one-to-one corresponding second insertion holes are provided. By providing multiple second guide pins, the connection strength of the two second vertical stiffeners 14 can be further improved. Furthermore, when the two second vertical stiffeners 14 are joined together, since the second guide pins are located between the two second vertical stiffeners 14, the second guide pins do not affect the air intake. In this embodiment, five second guide pins and five second insertion holes are provided.

[0049] Optionally, two first screws 15 are provided, and two first through holes and two corresponding first threaded holes 134 are provided. That is, one of the two first vertical rib plates 13 is provided with two first through holes, and the other is provided with two first threaded holes 134 that correspond one-to-one with the first through holes. The two first screws 15 are respectively inserted into the two first through holes and screwed into the corresponding first threaded holes 134. By providing only two first screws 15 and cooperating with the first guide pin 132, the connection between the two first vertical rib plates 13 is ensured to be firm, while the disassembly and assembly process is simplified, and the smooth airflow is also guaranteed.

[0050] Optionally, two second screws 17 are provided, and the number of second through holes and second threaded holes are both two and correspond one-to-one. That is, one of the two second vertical rib plates 14 is provided with two second through holes, and the other is provided with two second threaded holes that correspond one-to-one with the second through holes. The two second screws 17 are respectively inserted into the two second through holes and screwed into the corresponding second threaded holes. By providing only two second screws 17 and cooperating with the second guide pin, the connection between the two second vertical rib plates 14 is ensured to be firm, while the disassembly and assembly process is simplified, and the smooth air intake is also guaranteed.

[0051] Optionally, both the front air outlet 111 and the rear air outlet 121 are provided with a plurality of first horizontal grilles 16 spaced apart along the height direction of the shell body 1. One end of the first horizontal grille 16 is connected to the corresponding first vertical rib 13. Since the thickness of the first vertical rib 13 is small, in order to improve the connection firmness of the first screw 15, each first threaded hole 134 extends to a corresponding first horizontal grille 16, and the end of the first horizontal grille 16 with the first threaded hole 134 is provided with a connecting part 161. The longitudinal cross-sectional dimension of the connecting part 161 gradually increases from the inside to the outside of the shell body 1. This structural design reduces the wind-blocking area of ​​the first horizontal grille 16 with the first threaded hole 134 and reduces the air outlet resistance.

[0052] Optionally, both the front air inlet 112 and the rear air inlet 122 are provided with second horizontal grid plates 18 spaced apart along the height direction of the shell body 1. One end of the second horizontal grid plate 18 is connected to the corresponding second vertical rib plate 14. Since the thickness of the second vertical rib plate 14 is the same as the thickness of the first vertical rib plate 13, in order to ensure the connection strength of the second screw 17, the second threaded hole also needs to extend into the corresponding second horizontal grid plate 18.

[0053] Furthermore, the second horizontal grille 18 is inclined upward in the direction from the air inlet to the air outlet. By setting the second horizontal grille 18 to be inclined upward, the air inlet can be rainproof and the internal parts can be prevented from being exposed.

[0054] Refer to Figure 1The side-discharge heat pump water heater casing also includes a top cover 2 and a base 3. The top cover 2 is located at the upper end of the casing body 1 and is connected to the front casing 11 and / or the rear casing 12. The base 3 is located at the lower end of the casing body 1 and is connected to the front casing 11 and / or the rear casing 12. In this embodiment, the top cover 2 and the rear casing 12 are connected by a third screw, and the top cover 2 is provided with a first slot, into which the upper end of the rear casing 12 is inserted. The base 3 and the rear casing 12 are connected by a fourth screw, and the base 3 is provided with a second slot, into which the lower end of the rear casing 12 is inserted.

[0055] This utility model embodiment also provides a side-discharge heat pump water heater. The side-discharge heat pump water heater shell described above can improve the convenience of later maintenance and improve the energy efficiency of the side-discharge heat pump water heater.
