Of course, it can be understood that in some other embodiments, the connecting structure may not be limited to a screw-connected assembly. The connecting member 32 is connected to the fixing bracket 31 and can be detachably connected to the fixing bracket 31. For example, it can be detachably connected to the fixing bracket 31 by setting a connecting structure, and the connecting structure can be a screw-connected assembly. The connecting member 32 can be configured to be connected to the water tank 100, specifically, it can be connected to the outer wall of the inner liner of the water tank 100. The fixing bracket 31 can be at least partially arranged on the periphery of the insulation structure of the water tank 100.

[0040] In some embodiments, the fixing bracket 31 may include a first mounting substrate 311, a second mounting substrate 312, a first reinforcing plate 313, and a second reinforcing plate 314. The first mounting substrate 311 may be a square plate, which may be disposed on the support structure 111 and located on the support end surface 1112. The second mounting substrate 312 is disposed on the first mounting substrate 311, connected to the first mounting substrate 311 and extending from the support column 1111 to the water tank 100, that is, disposed perpendicular to the first mounting substrate 311, and in some embodiments, it may be rectangular. The first reinforcing plate 313 and the second reinforcing plate 314 are disposed on two opposite sides of the second mounting substrate 312 and are connected to the first mounting substrate 311 and the second mounting substrate 312.

[0043] The fixing member 4 can be installed on the side of the support member 16 facing the water tank 100, so as to prevent the water inside the water tank 100 from shaking during the operation of the water tank 100, thereby preventing the bottom fixing seat 3 from being damaged due to excessive force. The fixing member 4 and the support member 16 are fixed to form a fixation in the middle of the water tank 100, thereby increasing the stability of the whole machine. The installation position of the fixing member 4 can be higher than the position where the center of gravity of the water tank 100 is located. Of course, it can be understood that in some other embodiments, the installation position of the fixing member 4 can be flush with the position where the center of gravity of the water tank 100 is located. It can be fixedly connected to the fixed water tank 100 from the side of the water tank 100, which helps to improve the stability of the water tank 100 when running in the domestic hot water, partial heat recovery or full heat recovery mode. And because the water tank 100 is placed vertically and the volume of the water tank 100 is large, the center of gravity of the water tank 100 will be above, and the fixing ear is located above the middle of the water tank 100, and is fixed above the center of gravity, which is conducive to increasing the overall stability of the water tank 100.

[0044] like Figures 4 to 6As shown, specifically, the fixing member 4 includes a fixing plate 41 and at least one fixing ear 42. The fixing plate 41 is installed on the main body 1, specifically on the upper part of the support member 16 and towards the side of the water tank 100, that is, the installation height is higher than the height of the center of gravity of the water tank 100. The fixing ear 42 can be installed on the fixing plate 41. It can be two. In some other embodiments, the fixing ear 42 is not limited to two. The fixing ear 42 can include a first fixing portion 421 and two second fixing portions 422. The two second fixing portions 422 are located on both sides of the first fixing portion 421. In some other embodiments, the second fixing portions 422 are not limited to two, and can be one or more than two. The first fixing portion 421 and the two second fixing portions 422 can be integrally formed, and the fixing ear 42 is generally in a "J" shape. The first fixing portion 421 can be in a plate shape. The two second fixing portions 422 are arranged on both sides of the first fixing portion 421. One end of each second fixing portion 422 is connected to the first fixing portion 421, and the other end extends towards the water tank 100 to be connected to the water tank 100. Each second fixing portion 422 can be partially bent to be attached to the outer wall of the water tank 100, and then can be connected to the water tank 100 by welding or screw connection with the water tank 100. In some embodiments, the fixing member 4 can be an overall sheet metal part.

[0045] Specifically, in some embodiments, each second fixing portion 422 can include a first connecting portion 4221 and a second connecting portion 4222. One end of the first connecting portion 4221 is connected to the first fixing portion 421, and the other end extends towards the water tank 100. The second connecting portion 4222 is connected to the end of the first connecting portion 4221 away from the first fixing portion 421 and is bent with the first connecting portion 4221. It can be bent in a direction away from the other second fixing portion 422, and the second connecting portion 4222 fits the outer wall of the water tank 100 and is welded or screwed to the water tank 100. In some embodiments, the connecting structure can be a screw assembly.

[0046] In some embodiments, the air source heat pump can further include components such as an outdoor heat exchanger 200, a compressor, a liquid storage tank 300, a plate heat exchanger 400, etc. Among them, the outdoor heat exchanger 200 can be arranged in the second cavity 2b. When the air source heat pump operates, the external air can exchange heat with the outdoor heat exchanger 200. The heat of the outdoor air is transferred to the outdoor heat exchanger 200 by the way of the air contacting the outdoor heat exchanger 200, so as to achieve the purpose of the air source heat pump absorbing the heat in the air. The compressor, the liquid storage tank 300, and the plate heat exchanger 400 can be installed on the chassis 11 and are located between the water receiving tray 17 and the chassis 11.

[0047] In some embodiments, the air source heat pump can complete heating, cooling and preparation of domestic hot water without the need for additional matching equipment such as hydraulic modules and domestic hot water modules, thereby improving the integration of the product, and improving the overall stability through the water tank installation structure, and reducing the complexity of installing multiple devices during the engineering installation process, thereby improving the user experience.

[0048] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model.
