Description

Technical Field

[0001] The present application relates to the technical field of heat pumps, and in particular to a water heater head and a heat pump water heater. Background Art

[0002] In the related art, the height of a heat pump water heater with a water heater head is generally more than 1.5 m. During delivery to customers, the heat pump water heater often needs to be placed horizontally in a small transport vehicle for transportation, and the heat pump water heater cannot be kept upright.

[0003] However, during horizontal transportation, the compressor in the head of the water heater will tilt to the horizontal side at a large angle under the influence of its own weight. At the same time, since the compressor is connected to the heat exchanger through piping, the compressor will pull the heat exchanger to tilt together through the piping. Coupled with the vibration generated during transportation, it is not only easy to cause overstress damage to the installation structure of the compressor, but also easy to cause the piping to deform or even rupture. This kind of irreversible damage cannot be restored after the heat pump water heater is placed upright. Utility Model Content

DETAILED DESCRIPTION

[0038] In the description of the embodiments of the present application, it should be noted that the term "first direction" is based on the attached Figure 2 These directional terms are only used to facilitate the description of the embodiments of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application.

[0039] The present application embodiment provides a heat pump water heater. Figure 1 The heat pump water heater comprises a water tank 200 and a water heater head 100 , and the water heater head 100 is arranged on the top of the water tank 200 .

[0040] The heat pump water heater is in an upright position during use, and in the upright position, the water heater head 100 is located on the top of the water tank 200. During the transportation of the heat pump water heater, the heat pump water heater can be placed horizontally, and in the horizontal position, the water heater head 100 is located on one side of the water tank 200 in the horizontal direction.

[0041] See also Figure 1 , Figure 2 and Figure 3 The water heater head 100 of the embodiment of the present application includes a housing 10 , a compressor 20 and a horizontal support assembly 30 .

[0042] The shell 10 includes a chassis 11 and a cover 12 covering the chassis 11. The compressor 20 and the horizontal support assembly 30 are both arranged in the shell 10, and the horizontal support assembly 30 is arranged on the horizontal side of the compressor 20 to support the compressor 20 when the water heater head 100 is in a horizontal state.

[0043] The lying side of the compressor 20 is the side to which the gravity direction of the compressor 20 is directed when the water heater head 100 is in a lying state, that is, the side of the compressor 20 close to the ground.

[0044] It should be noted that the horizontal direction of the heat pump water heater has been pre-set when the heat pump water heater is manufactured (generally, a mark is set on the heat pump water heater to indicate the horizontal direction). During the subsequent transportation of the heat pump water heater, the operator needs to place the heat pump water heater horizontally in the pre-set direction. Therefore, the horizontal side of the compressor 20 is fixed.

[0045] See also Figure 2 and Figure 8 The water heater head 100 is further provided with a heat exchanger 40 and a pipe 50 , and the compressor 20 is connected to the heat exchanger 40 through the pipe 50 .

[0046] Since the compressor 20 tends to tilt and move toward the horizontal side under the action of its own gravity, a horizontal support assembly 30 is provided on the horizontal side of the compressor 20. Therefore, when the water heater head 100 is in a horizontal state, a certain supporting force can be provided to the compressor 20, so as to prevent the compressor 20 from excessively tipping toward the horizontal side to a certain extent. As a result, not only the possibility of damage to the compressor 20 due to overstress is reduced, but also deformation or even rupture of the piping 50 can be better avoided, thereby reducing or even eliminating the horizontal damage to the water heater head 100 caused by horizontal placement.

[0047] The horizontal support assembly 30 can have various structural forms. For example, in one embodiment, please refer to Figure 2 , Figure 6 and Figure 7The horizontal support assembly 30 includes a support plate 31 arranged on the chassis 11. When the water heater head 100 is in an upright state, there is a gap between the support plate 31 and the compressor 20. When the water heater head 100 is in a horizontal state, the compressor 20 tilts toward the horizontal side under the effect of its own gravity to contact the support plate 31 arranged on the horizontal side. That is to say, in the upright state, the support plate 31 does not contact the compressor 20. When the water heater head 100 is in a horizontal state, the compressor 20 tilts toward the horizontal side at a certain angle under the effect of its own gravity and contacts the support plate 31 arranged on the horizontal side, so that the support plate 31 can support the compressor 20.

[0048] Since the compressor 20 will generate certain vibrations during operation, when the water heater head 100 is in an upright state, the support plate 31 is spaced apart from the compressor 20, which can better prevent the support plate 31 from colliding with the compressor 20 during operation and generating abnormal sounds or noises.

[0049] For example, see Figure 2 , Figure 6 and Figure 7 The support plate 31 includes a support body 311 and two reinforcement parts 312 . The support body 311 faces the compressor 20 . The two reinforcement parts 312 are respectively arranged on opposite sides of the support body 311 and folded in a direction away from the compressor 20 .

[0050] When the water heater head 100 is in a horizontal position, the compressor 20 is in contact with the support body 311 facing the compressor 20, and the support body 311 provides anti-dumping support for the compressor 20, and the reinforcement parts 312 arranged on the opposite sides of the support body 311 are used to disperse the stress on the support body 311 when supporting the compressor 20, thereby effectively increasing the overall structural stability of the support plate 31 and preventing the support body 311 from being deformed and affecting the anti-dumping effect to a certain extent.

[0051] In order to enable each reinforcement part 312 to play a better reinforcement role, preferably, the angle between each reinforcement part 312 and the support body 311 can be 90° to 160° (including the end points).

[0052] Please continue reading Figure 2 , Figure 6 and Figure 7, the two reinforcing parts 312 can be located on opposite sides of the support body 311 along the first direction, wherein the first direction is parallel to the chassis 11. The support plate 31 also includes fixing parts 313 corresponding to the reinforcing parts 312 one by one, and each fixing part 313 is arranged on a side of the corresponding reinforcing part 312 close to the chassis 11, and is respectively fastened to the chassis 11. In other words, the support body 311 is fastened to the chassis 11 by the two fixing parts 313 arranged on the side close to the chassis 11, and the connection stability between the support plate 31 and the chassis 11 is effectively improved by arranging the reinforcing parts 312 for the support body 311 on opposite sides in the first direction parallel to the chassis 11.

[0053] The fixing portion 313 and the chassis 11 may be fastened together by fasteners such as pins and screws.

[0054] In other embodiments, the two reinforcement parts 312 may also be located on opposite sides of the support body 311 along other directions. For example, the two reinforcement parts 312 may also be located on opposite sides of the support body 311 along the top and bottom directions of the heat pump water heater.

[0055] In one embodiment, please refer to Figure 3 and Figure 4 The horizontal support assembly 30 further includes an elastic block 32 , which is sandwiched between the support plate 31 and the cover shell 12 .

[0056] The elastic block 32 is made of a material capable of producing elastic deformation, such as rubber. When the water heater head 100 is in a horizontal position, the elastic block 32 is compressed under the action of elastic force, thereby not only enhancing the supporting force provided by the support plate 31 to the compressor 20, and preventing the support plate 31 from tipping over or deforming to a certain extent, but also decomposing the instantaneous impact force of the compressor 20 when it is horizontally placed.

[0057] In another embodiment, see Figure 5 The horizontal support assembly 30 may only be provided with the elastic block 32 without providing the support plate 31 . For example, the elastic block 32 may be sandwiched between the compressor 20 and the cover 12 .

[0058] Among them, the elastic block 32 can be arranged on the compressor 20, and when the water heater head 100 is in an upright state, the elastic block 32 and the cover shell 12 maintain a gap or contact. The elastic block 32 can also be arranged on the cover shell 12, and when the water heater head 100 is in an upright state, the elastic block 32 and the compressor 20 maintain a gap or contact. Alternatively, when the water heater head 100 is in an upright state, the elastic block 32 can be respectively connected to the elastic block 32 and the cover shell 12.

[0059] Since the material of the elastic block 32 is relatively soft, during the operation of the compressor 20 , the elastic block 32 contacts the compressor 20 and hardly generates abnormal sound or noise.

[0060] In one embodiment, please refer to Figure 2 and Figure 8 The water heater head 100 may also be provided with a clamping assembly 60, which includes a clamp 61. The clamping assembly 60 is arranged on the chassis 11. The clamp 61 clamps the pipe 50 to prevent the pipe 50 from excessively shaking and causing deformation or rupture to a certain extent.

[0061] The number of the clamping components 60 can be one or more, and can be flexibly adjusted according to the number and structure of the pipes 50 in actual application.

[0062] In one embodiment, please refer to Fig. 9 and Fig.10 The clamp 61 includes a clamping portion 611 having an opening 611 a , and the pipe 50 can be directly inserted into the clamping portion 611 from the opening 611 a , so the assembly method is simple and convenient.

[0063] For example, see Fig. 9 and Fig.10 The clamp 61 also includes two mounting plates 612 having first mounting holes 612a. The two mounting plates 612 are arranged on the clamping portion 611 and are respectively located on opposite sides of the opening 611a. The clamping assembly 60 also includes a fastener (not shown in the figure). The fastener is passed through the first mounting holes 612a of the two mounting plates 612 to close the opening 611a.

[0064] Specifically, after the piping 50 is inserted into the clamping portion 611 from the opening 611a, fasteners are inserted into the first mounting holes 612a of the two mounting plates 612 to close the opening 611a, so that the piping 50 inserted into the clamping portion 611 cannot fall out of the closed opening 611a, thereby reducing the risk of the piping 50 falling out of the clamp 61 due to vibration during transportation.

[0065] Please continue reading Fig. 9 and Fig.10 The clamping assembly 60 further includes a mounting seat 62 having a second mounting hole 62a, the mounting seat 62 being disposed on the chassis 11, and the fastener is also inserted into the second mounting hole 62a, so that the clamp 61 is fastened to the mounting seat 62. That is, when installing the clamp 61, the pipe 50 can be first inserted into the clamping portion 611, and then the fastener is inserted into the second mounting hole 62a and the two first mounting holes 612a of the two mounting pieces 612 at the same time, thereby quickly completing the two steps of closing the opening 611a and installing the clamp 61.

[0066] In one embodiment, please refer to Fig. 9 and Fig.10 The clamp 61 also includes a protective pad 613, which at least covers one side of the clamping portion 611 close to the pipe 50. The protective pad 613 is used to buffer the impact force between the pipe 50 and the clamping portion 611, effectively improving the service life of the pipe 50 and also reducing the vibration transmission of the pipe 50.

[0067] In one embodiment, please refer to Figures 11 to 13 The water heater head 100 further includes a mounting column 70 , a flexible foot pad 80 , and a foot pad baffle 90 having a connecting portion 91 and a stop portion 92 .

[0068] The mounting column 70 is disposed on the chassis 11, and the flexible foot pad 80 is connected to the compressor 20 and movably mounted on the mounting column 70. The compressor 20 is non-fixedly connected to the chassis 11 through the flexible foot pad 80. During the operation of the compressor 20, the flexible foot pad 80 can move along the mounting column 70 to achieve a vibration reduction effect.

[0069] Please continue reading Figures 11 to 13 The connecting portion 91 of the foot pad baffle 90 is connected to the chassis 11, and the stopper 92 is sleeved on the mounting column 70 and is located on the side of the flexible foot pad 80 away from the chassis 11. When the water heater head 100 is in a vertical state, there is a gap between the stopper 92 and the flexible foot pad 80.

[0070] The stopper 92 is used to stop the flexible foot pad 80 when the water heater head 100 is in a lying state. Specifically, when the water heater head 100 is in an upright state, there is a gap between the stopper 92 and the flexible foot pad 80, so when the compressor 20 enters the working state, the stopper 92 does not contact the flexible foot pad 80, and the foot pad baffle 90 does not transmit the vibration generated by the compressor 20, nor does it affect the movement of the flexible foot pad 80. Therefore, when the compressor 20 is working normally, the foot pad baffle 90 does not need to be removed.

[0071] When the water heater head 100 is in a horizontal position, the stopper 92 mounted on the mounting column 70 can stop the flexible foot pad 80, thereby preventing the flexible foot pad 80 from excessively moving with the tilting of the compressor 20 to a certain extent, thereby also preventing the compressor 20 from excessively tilting to a certain extent.
