Description

Technical Field

[0001] The utility model relates to heat pump equipment technology, and more specifically, to a heat pump water heater and a head assembly thereof. Background Art

[0002] The existing heat pump water heater has a head including a housing, a heat exchanger assembly, a fan assembly and a compressor. The compressor is a vertical compressor. The heat exchanger assembly is vertically arranged in the housing and divides the interior of the housing into an air inlet duct and an air outlet duct. The fan assembly is vertically arranged in the air outlet duct. The vertical compressor is vertically arranged in the air inlet duct and installed on the bottom wall of the housing. The height of the vertical compressor is relatively high. When the heat pump water heater is transported horizontally, the top swing of the vertical compressor is particularly large, which will cause excessive wear of the shock absorber between the vertical compressor and the bottom wall of the housing. The horizontal transportation of the vertical compressor will also cause oil return problems and cause poor performance of the vertical compressor. Furthermore, when the heat pump water heater is subjected to a tipping test, the vertical compressor will also be more likely to tear the bottom wall of the housing due to the large swing of the top. Therefore, the heat pump water heater using a vertical compressor can only be transported vertically, but vertical transportation will significantly reduce the amount of heat pump water heaters that can be loaded into cabinets.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0025] The heat pump water heater provided in the embodiment of the utility model comprises a barrel body and a head assembly. Figures 1 to 4 As shown, the head assembly includes: a housing 100, the bottom wall of the housing 100 is mounted on the top of the barrel, the peripheral wall of the housing 100 has a first air port 110, and the top wall of the housing 100 has a second air port 120; a heat exchanger assembly 200, the heat exchanger assembly 200 is arranged in the housing 100, and the interior of the housing 100 is divided into a first air duct 10 and a second air duct that are connected, the first air duct 10 is located at one side of the second air duct, and the first air duct 10 includes the first air port 110, and the second air duct includes the second air port 120; a fan assembly 300, the fan assembly 300 is arranged in the second air duct; and a compressor, the compressor is arranged in the second air duct and is located below the fan assembly 300. Among them, the second air port 120 is located at the top of the second air duct, and the first air port 110 is located at the side of the first air duct 10 away from the second air duct.

[0026] The heat exchanger assembly 200 is arranged in the shell 100 and divides the interior of the shell 100 into a first air duct 10 and a second air duct that are connected. The first air duct 10 is located on one side of the second air duct. The surrounding wall of the shell 100 has a first air port 110, and the top wall of the shell 100 has a second air port 120. The first air duct 10 includes the first air port 110, and the second air duct includes the second air port 120. The compressor is located in the second air duct, so the compressor must be located on one side of the heat exchanger of the heat exchanger assembly 200, and the fan assembly 300 is located above the compressor. Therefore, the heat exchanger can be set as a U-shaped heat exchanger, a C-shaped heat exchanger, or a V-shaped heat exchanger. Compared with a plate heat exchanger, the heat exchange area of ​​the U-shaped heat exchanger, the C-shaped heat exchanger, or the V-shaped heat exchanger can be designed to be larger. Therefore, the head assembly of this scheme is applied to a heat pump water heater, and the heating performance of the heat pump water heater can be designed to be better.

[0027] The first air outlet 110 is set as an air inlet, which is connected to the room, and the second air outlet 120 is set as an air outlet, which is connected to the outside through an air duct. When the fan assembly 300 is running, a wind beam is formed inside the housing 100, which flows from the air inlet to the air outlet through the heat exchanger and the fan assembly 300 in sequence. The low-temperature wind beam formed after heat exchange with the heat exchanger is discharged to the outside through the air outlet and the air duct.

[0028] In some examples, such as Figures 2 to 4 As shown, the heat exchanger assembly 200 includes a heat exchanger 210 and a support frame 220. The heat exchanger 210 is connected to the support frame 220 and together divides the interior of the shell 100 into a first air duct 10 and a cavity 20. The bottom wall of the shell 100, the heat exchanger 210 and the support frame 220 together form a fourth air duct 30. The fourth air duct 30 is located on one side of the first air duct 10. The cavity 20 is located above the fourth air duct 30 and is connected to the fourth air duct 30. The compressor is arranged in the fourth air duct 30. The second air port 120 is located on the top wall of the cavity 20. The second air duct also includes the fourth air duct 30.

[0029] Furthermore, if Figure 2 and Figure 3 As shown, the support frame 220 includes: a separator ring 221, which is horizontally placed in the shell 100, and the separator ring 221, the top wall of the shell 100 and the peripheral wall of the shell 100 above the separator ring 221 together form a cavity 20; and a separator plate 222, the separator plate 222 and the heat exchanger 210 are both vertically arranged below the separator ring 221, and the heat exchanger 210 is located on one side of the separator plate 222, the heat exchanger 210, the separator ring 221, the bottom wall of the shell 100 and the separator plate 222 together form a fourth air duct 30, the fourth air duct 30 is connected to the cavity 20 through the inner hole of the separator ring 221, the first air port 110 is located on the side of the heat exchanger 210 facing the outside of the fourth air duct 30, and the first air duct 10 is formed between the heat exchanger 210, the first air port 110, the separator ring 221 and the bottom wall of the shell 100.

[0030] Furthermore, if Figures 2 to 4 As shown, the support frame 220 also includes: an air guide ring 223, which is sleeved outside the fan assembly 300, the upper end of the air guide ring 223 is connected to the top wall of the shell 100 in the cavity 20, the lower end of the air guide ring 223 extends from the inner hole of the separation ring 221 into the fourth air duct 30, and the interior of the air guide ring 223 forms a fifth air duct 40, the second air outlet 120 is connected to the fourth air duct 30 through the fifth air duct 40, and the second air duct also includes the fifth air duct 40. In this solution, the lower part of the air guide ring 223 is arranged in the fourth air duct 30, and the space inside the fourth air duct 30 is used, so that the height of the shell 100 can be further reduced.

[0031] The fan assembly 300 is running, and the indoor air is discharged from the second air outlet 120 to the outside after passing through the first air duct 10, the heat exchanger 210, the fourth air duct 30 and the fifth air duct 40 from the first air outlet 110 in sequence. Among them, the peripheral wall of the air guide ring 223 is sealed with the hole wall of the inner hole of the separation ring 221, and the upper end of the air guide ring 223 is sealed with the mouth wall of the second air outlet 120, and the caliber of the lower end of the air guide ring 223 is smaller than the caliber of the upper end of the air guide ring 223. Among them, the peripheral wall of the air guide ring 223 includes a tapered peripheral wall, and the central angle of the tapered peripheral wall is set to 15 degrees to 60 degrees, so that the air guide effect of the air guide ring 223 is better. Furthermore, the lower end of the air guide ring 223 is provided with an annular guide arc edge extending upward from the inner side of the air guide ring 223, and the guide arc edge guides the wind beam from the fourth air duct 30 to the fifth air duct 40.

[0032] In some examples, such as Figures 2 to 4 As shown, the fan assembly 300 includes a fan blade and a motor (not shown in the figure), the motor is fixed to the top wall of the housing 100, the fan blade is located in the fifth air duct 40, and is in driving connection with the rotating shaft of the motor. The motor drives the fan blade to rotate, and a wind beam is formed inside the housing 100, which flows from the first air outlet 110 to the second air outlet 120 through the first air duct 10, the heat exchanger 210, the fourth air duct 30 and the fifth air duct 40 in sequence.

[0033] In some examples, such as Figure 3 and Figure 4 As shown, the separation ring 221, the bottom wall of the housing 100, the peripheral wall of the housing 100 below the separation ring 221 and the side of the separation plate 222 facing away from the fourth air duct 30 together form an electric control installation cavity (located at Figure 4 The electric control installation cavity is configured to install an electric control unit (such as an electric control box). Figure 3 As shown, the partition plate 222 is sealed with the circumferential wall of the shell 100 at both ends of the circumference of the shell 100, the lower end of the partition plate 222 is sealed with the bottom wall of the shell 100, and the upper end of the partition plate 222 is sealed with the partition ring 221, so that the low-temperature air beam formed after passing through the heat exchanger 210 will not flow to the electronic control unit, so the electronic control unit will not have condensation and short-circuit damage.

[0034] It can be, for example Figure 3 As shown, the partition plate 222 and the partition ring 221 are an integral structure; or the partition plate 222 and the partition ring 221 may be separate structures, etc.; all of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present utility model, and will not be repeated here, and should all fall within the protection scope of the present application.

[0035] In some embodiments, Figure 3As shown, the partition plate 222 is a bent plate, the heat exchanger 210 is a U-shaped heat exchanger, a C-shaped heat exchanger or a V-shaped heat exchanger, and the heat exchanger 210 is sealed at both ends of the circumference of the shell 100 and the bent plate is sealed at both ends of the circumference of the shell 100. In this solution, the heat exchange area of ​​the heat exchanger 210 (i.e., the U-shaped heat exchanger, the C-shaped heat exchanger or the V-shaped heat exchanger) is larger, so that the head assembly is applied to the heat pump water heater, and the heating performance of the heat pump water heater is better.

[0036] In some embodiments, Figure 2 and Figure 3 As shown, the compressor is a horizontal compressor 400, which is installed on the bottom wall of the shell 100 in the fourth air duct 30. The height of the horizontal compressor 400 on the bottom wall of the shell 100 is significantly lower than that of the vertical compressor. In this way, when the heat pump water heater is transported horizontally, the swing of the top of the horizontal compressor 400 is very small, and the shock-absorbing parts between the horizontal compressor 400 and the bottom wall of the shell 100 are basically not worn. In addition, the horizontal compressor 400 is designed to prevent oil return. Therefore, the horizontal transportation of the heat pump water heater will not affect the performance of the horizontal compressor 400; furthermore, when the heat pump water heater is subjected to a tipping test, since the swing of the top of the horizontal compressor 400 is very small, the horizontal compressor 400 is less likely to tear the bottom wall of the shell 100; furthermore, compared with vertical transportation, the heat pump water heater using horizontal transportation has a larger product loading volume.

[0037] Furthermore, the refrigerant pipeline connected to the horizontal compressor 400 is arranged in the fourth air duct 30, so as to fully utilize the space in the fourth air duct 30, so that the structure of the head assembly is more compact, and the diameter and height are smaller.

[0038] To sum up, the technical solution provided by the embodiment of the utility model is that the heat exchanger assembly is arranged in the shell and divides the interior of the shell into a first air duct and a second air duct that are connected. The first air duct is located on one side of the second air duct, the peripheral wall of the shell has a first air outlet, and the top wall of the shell has a second air outlet. The first air duct includes the first air outlet, and the second air duct includes the second air outlet. The compressor is located in the second air duct, so the compressor must be located on one side of the heat exchanger of the heat exchanger assembly, and the fan assembly is located above the compressor. Therefore, the heat exchanger can be set as a U-shaped heat exchanger or a C-shaped heat exchanger. Compared with a plate heat exchanger, the heat exchange area of ​​the U-shaped heat exchanger or the C-shaped heat exchanger can be designed to be larger. Therefore, the head assembly of this scheme is applied to a heat pump water heater, and the heating performance of the heat pump water heater can be designed to be better.
