Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water heaters, in particular to an air energy water heater. BACKGROUND

[0002] The air energy water heater has a water tank, a water pipe, a water pipe seat and a decorative ring, wherein the water tank has an outer shell and an inner container arranged in the outer shell. The outer shell is provided with a through hole, and the water pipe seat is fixedly arranged outside the inner container and penetrates the through hole. The water pipe penetrates the water pipe seat, one end of the water pipe extends into the inner container, and the other end is connected to another water pipe outside, so as to communicate the space in the inner container with the other water pipe outside. The decorative ring is installed at the through hole of the outer shell to cover the gap and irregular part at the through hole, so that the air energy water heater looks more tidy, and plays a role of beautifying the appearance of the air energy water heater. When the air energy water heater is installed outdoors (for example, an open balcony or a roof) and encounters rainy weather, rainwater will seep through the gap between the decorative ring and the outer shell of the water tank, penetrate the through hole and enter the inside of the water tank, thereby corroding the inner container. If the inner container is severely corroded, the microchannel for the flow of refrigerant may be damaged, resulting in refrigerant leakage. Therefore, it is necessary to improve the structure of the air energy water heater to prevent rainwater from penetrating the through hole after flowing through the gap between the decorative ring and the outer shell of the water tank, thereby corroding the inner container. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide an air energy water heater in view of the above problems.

[0004] In order to solve the above problems, the technical scheme of the present application is as follows:

[0005] An air energy water heater, comprising:

[0006] a water tank comprising an outer shell and an inner container, the inner container being arranged in the outer shell, the outer shell having a bottom wall, a top wall and a vertical wall extending from the bottom wall to the top wall, the vertical wall being provided with a through hole with a whole-circle flange, the flange extending horizontally away from the inner container, and an outer peripheral surface of the flange being configured to enable rainwater reaching the outer peripheral surface of the flange to drip from the lowest part of the outer peripheral surface of the flange;

[0007] a water pipe seat penetrating the through hole and fixedly arranged in the inner container; and

[0008] The decorative ring comprises an inner extension and a ring-shaped decorative portion. The inner extension is fixedly sleeved on the water pipe base. The ring-shaped decorative portion extends from the inner extension away from one end of the inner container towards the outer shell. The inner extension and the ring-shaped decorative portion jointly enclose a containing space. The flange away from the one end of the inner container is entirely located in the containing space and is spaced apart from the ring-shaped decorative portion. The ring-shaped decorative portion is provided with a gap. The gap communicates the containing space with the outside. The gap is located below the flange.

[0009] The air energy water heater has at least the following beneficial effects:

[0010] When the air energy water heater is installed outdoors (for example, an open balcony or a roof) and encounters rainy weather, because the flange away from the one end of the inner container is entirely located in the containing space, rainwater cannot directly enter the through hole through the flange away from the one end of the inner container. The rainwater can only first flow downward through the gap between the upper portion of the ring-shaped decorative portion and the water tank shell. Some of the rainwater flows along the water tank shell to the outer peripheral surface of the flange. Then, under the action of gravity, the rainwater flows along the outer peripheral surface of the flange to the lowest part of the outer peripheral surface of the flange. Then, the rainwater drips from the lowest part of the outer peripheral surface of the flange to the side of the ring-shaped decorative portion facing the water tank shell. Finally, the rainwater flows to the outside through the gap and / or the gap between the lower portion of the ring-shaped decorative portion and the water tank shell. The other part of the rainwater flows downward along the side of the ring-shaped decorative portion facing the water tank shell. Because the flange is spaced apart from the ring-shaped decorative portion, this part of the rainwater cannot flow to the through hole through the side of the ring-shaped decorative portion facing the water tank shell. This part of the rainwater will eventually also flow to the outside through the gap and / or the gap between the lower portion of the ring-shaped decorative portion and the water tank shell.

[0011] In summary, when the air energy water heater is installed outdoors (for example, an open balcony or a roof) and encounters rainy weather, rainwater does not reach the through hole. Therefore, rainwater cannot penetrate into the water tank through the through hole to corrode the inner container.

[0012] In one of the embodiments, the gap is located at the lowest part of the containing space.

[0013] In this way, rainwater located at the lowest part of the containing space also flows to the outside through the gap, which is beneficial for the rainwater to quickly flow out of the containing space.

[0014] In one of the embodiments, the gap is located directly below the flange.

[0015] In this way, rainwater dripping from the flange can quickly flow out of the containing space.

[0016] In one of the embodiments, the gap faces downward.

[0017] In this way, rainwater can quickly flow out of the containing space.

[0018] In one of the embodiments, the decorative ring is provided with an interference fit on the water pipe base.

[0019] In this way, on the one hand, the decorative ring and the water pipe base can be quickly and reliably assembled together; on the other hand, the gap between the decorative ring and the water pipe base is eliminated, which can prevent rainwater from flowing through the gap between the decorative ring and the water pipe base to the inner container and corroding the inner container.

[0020] In one of the embodiments, the outer circumferential surface of the flange is a cylindrical surface.

[0021] In this way, rainwater can be prevented from staying on the outer circumferential surface of the flange, and the rainwater on the outer circumferential surface of the flange can be quickly dripped.

[0022] In one of the embodiments, the part of the standing wall other than the flange is a standing wall body, the decorative ring is an elastic member, and the decorative ring abuts against the standing wall body so that the decorative ring is attached to the standing wall body.

[0023] In this way, rainwater can be blocked outside the air energy water heater, the gap between the upper part of the annular decorative part and the water tank shell can be prevented, and the inner container can be protected.

[0024] In one of the embodiments, the part of the decorative ring close to the standing wall body is contouredly fitted with the standing wall body.

[0025] In this way, the attachment of the decorative ring to the shell can be improved, rainwater can be blocked outside the air energy water heater, the gap between the upper part of the annular decorative part and the water tank shell can be prevented, and the inner container can be protected.

[0026] In one of the embodiments, the part of the flange away from the inner container is formed by a secondary flange through a stamping forming process, the secondary flange extends in a direction away from the through hole, the part of the standing wall other than the flange is a standing wall body, and the secondary flange is spaced apart from the standing wall body.

[0027] In this way, even if the air energy water heater is slightly tilted after installation, rainwater cannot reach the through hole due to the blocking of the secondary flange.

[0028] In one of the embodiments, the part of the standing wall other than the flange is a standing wall body, and the angle between the flange and the standing wall body is an acute angle.

[0029] In this way, even if the air energy water heater is slightly tilted after installation, rainwater will be blocked by the flange and cannot reach the through hole. BRIEF DESCRIPTION OF DRAWINGS

[0046] Referring to Figures 1 to 8 The air energy water heater comprises a water tank 1, a water pipe base 2 and a decorative ring 3. The water tank 1 comprises an outer shell 11 and an inner container 12, the inner container 12 is arranged in the outer shell 11, the outer shell 11 has a bottom wall 111, a top wall 112 and a vertical wall 113 extending from the bottom wall 111 to the top wall 112. A through hole 1131 with a whole-turn flange 1132 is arranged on the vertical wall 113, the flange 1132 extends horizontally in a direction away from the inner container 12. The water pipe base 2 is arranged through the through hole 1131 and is fixed to the inner container 12. The decorative ring 3 comprises an inner extension 31 and an annular decorative part 32, the inner extension 31 is fixedly sleeved on the water pipe base 2, the annular decorative part 32 extends obliquely from an end of the inner extension 31 away from the inner container 12 towards the outer shell 11, the inner extension 31 and the annular decorative part 32 jointly enclose a containing space 33, and an end of the flange 1132 away from the inner container 12 is located in the containing space 33. A gap 321 is arranged on the annular decorative part 32, the gap 321 communicates the containing space 33 with the outside, and the gap 321 is located below the flange 1132. In order to prevent rainwater from staying on the outer circumferential surface of the flange 1132, the outer circumferential surface of the flange 1132 is configured to enable rainwater reaching the outer circumferential surface of the flange 1132 to drip from the lowest part of the outer circumferential surface of the flange 1132. In order to prevent rainwater from flowing to the through hole 1131 through the annular decorative part 32, the end of the flange 1132 away from the inner container 12 is arranged in a spaced-apart manner with the annular decorative part 32.

[0047] The air energy water heater is installed in an upright state. Specifically, referring to Figures 1 to 4 The air energy water heater comprises a foot pad 4, the foot pad 4 is fixed to the bottom wall 111, and after installation is completed, the air energy water heater contacts the ground through the foot pad 4. In other embodiments, the foot pad 4 can also not be arranged on the bottom wall 111 of the air energy water heater, and the bottom wall 111 of the air energy water heater directly contacts the ground.

[0048] When the air energy water heater is installed outdoors (for example: open balcony, roof) and encounters rain, because the end of the turn-up 1132 away from the inner container 12 is entirely located in the containing space 33, rain cannot directly enter the through hole 1131 through the end of the turn-up 1132 away from the inner container 12. Rain can only first flow downward through the gap between the upper part of the ring-shaped decorative part 32 and the outer shell 11 of the water tank 1, wherein: part of the rain flows along the outer shell 11 of the water tank 1 to the outer peripheral surface of the turn-up 1132, after which the rain flows along the outer peripheral surface of the turn-up 1132 to the lowest part of the outer peripheral surface of the turn-up 1132 under the action of gravity, after which the rain drips from the lowest part of the outer peripheral surface of the turn-up 1132 onto the side of the ring-shaped decorative part 32 facing the outer shell 11 of the water tank 1, and finally the rain flows to the outside through the gap between the lower part of the ring-shaped decorative part 32 and the outer shell 11 of the water tank 1 and / or the gap 321; another part of the rain flows downward along the side of the ring-shaped decorative part 32 facing the outer shell 11 of the water tank 1, because the turn-up 1132 is spaced apart from the ring-shaped decorative part 32, this part of the rain cannot flow to the through hole 1131 through the side of the ring-shaped decorative part 32 facing the outer shell 11 of the water tank 1, and this part of the rain will eventually also flow to the outside through the gap between the lower part of the ring-shaped decorative part 32 and the outer shell 11 of the water tank 1 and / or the gap 321.

[0049] In summary, when the air energy water heater is installed outdoors (for example: open balcony, roof) and encounters rain, rain will not reach the through hole 1131, and therefore rain cannot penetrate into the inside of the water tank 1 through the through hole 1131 to corrode the inner container 12.

[0050] Referring to Figure 5 and Figure 8 , the gap 321 is located at the lowest part of the containing space 33. In this way, rain located at the lowest part of the containing space 33 will also flow to the outside through the gap 321, which is conducive to the rapid flow of rain out of the containing space 33.

[0051] Referring to Figure 5 , the gap 321 is located directly below the turn-up 1132. This is conducive to the rapid flow of rain that drips from the turn-up 1132 out of the containing space 33.

[0052] Referring to Figure 5 , the gap 321 faces downward. This is conducive to the rapid flow of rain out of the containing space 33.

[0053] In other embodiments, the gap 321 can also be located near the lowest part of the containing space 33, can also be located below the side of the turn-up 1132, and can also face the horizontal direction.

[0054] Referring to Figure 5The decorative ring 3 is in interference fit with the water pipe base 2. On the one hand, this facilitates quick and reliable assembly of the decorative ring 3 and the water pipe base 2 together; on the other hand, this eliminates the gap between the decorative ring 3 and the water pipe base 2, which can prevent rainwater from flowing through the gap between the decorative ring 3 and the water pipe base 2 to the inner container 12 and corroding the inner container 12.

[0055] Referring to Figure 7 The outer peripheral surface of the flange 1132 is a cylindrical surface. This can prevent rainwater from staying on the outer peripheral surface of the flange 1132, and is conducive to the rainwater on the outer peripheral surface of the flange 1132 quickly dripping off.

[0056] In some embodiments, in order to prevent rainwater from staying on the outer peripheral surface of the flange 1132, the outer peripheral surface of the flange 1132 is an elliptical cylindrical surface. In these embodiments, preferably, in the cross-sectional ellipse of the flange 1132, the major axis is vertical and the minor axis is horizontal, which is conducive to the rainwater on the outer peripheral surface of the flange 1132 quickly dripping off.

[0057] In some embodiments, the outer peripheral surface of the flange 1132 is a square cylindrical surface, and in the cross-sectional square of the flange 1132, one diagonal is vertical and the other diagonal is horizontal. This can prevent rainwater from staying on the outer peripheral surface of the flange 1132, and is conducive to the rainwater on the outer peripheral surface of the flange 1132 quickly dripping off.

[0058] In other embodiments, the decorative ring 3 can also be bonded to the water pipe base 2.

[0059] Referring to Figure 6 The part of the vertical wall 113 other than the flange 1132 is a vertical wall body 1133. In some embodiments, the decorative ring 3 is a resilient member, and the decorative ring 3 abuts against the vertical wall body 1133 to make the decorative ring 3 fit the vertical wall body 1133. This is conducive to blocking rainwater outside the air energy water heater, preventing rainwater from passing through the gap between the upper part of the annular decorative part 32 and the outer shell 11 of the water tank 1, and protecting the inner container 12.

[0060] Preferably, the part of the decorative ring 3 close to the vertical wall body 1133 is contoured to fit the vertical wall body 1133. This is conducive to improving the fit of the decorative ring 3 with the outer shell 11, blocking rainwater outside the air energy water heater, preventing rainwater from passing through the gap between the upper part of the annular decorative part 32 and the outer shell 11 of the water tank 1, and protecting the inner container 12.

[0061] In some embodiments, the part of the flange 1132 away from the inner container 12 is formed by a secondary flange through a stamping forming process, the secondary flange extends in a direction away from the through hole 1131, and the secondary flange is spaced apart from the vertical wall body 1133. In this way, even if the air energy water heater is slightly tilted after installation, rainwater cannot reach the through hole 1131 due to the blocking of the secondary flange.

[0062] In some embodiments, the included angle between the flange 1132 and the main body 1133 of the stand wall is an acute angle. In this way, even if the air water heater is slightly tilted after installation, rainwater will be blocked by the flange 1132 and cannot reach the through hole 1131. Exemplarily, the outer circumferential surface of the flange 1132 is in the shape of a truncated cone side, and the through hole 1131 is gradually flared in a direction away from the inner container 12. Preferably, the included angle between the flange 1132 and the main body of the shell 11 is less than or equal to 45°.

[0063] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure as long as the combination does not result in contradictions.

[0064] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the protection scope of the present application. It should be noted that, for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
