[0039] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0041] The heat pump device of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0042] like Figures 1 to 4 As shown, this embodiment discloses a heat pump device, including: a casing 1, the casing 1 having an inner cavity and an air outlet 105 communicating with the inner cavity; a heat pump mechanism 2, at least a portion of which is disposed in the inner cavity of the casing, the heat pump mechanism 2 including a compressor, a condenser 21, a throttling device and an evaporator 22 connected end to end to form a refrigerant circuit; a control mechanism 3, the control mechanism 3 including a mounting housing 31 and a control element 32, the mounting housing 31 being disposed on the casing 1, the mounting housing 31 having a mounting cavity 302 communicating with the air outlet 105, the control element 32 being disposed in the mounting cavity 302; and a fan assembly 4, at least a portion of which is located in the inner cavity of the casing, the fan assembly 4 being used to drive the air in the inner cavity of the casing and the mounting cavity 302 to be discharged outward through the air outlet 105, so as to remove the heat generated by the heat pump mechanism 2 and the control element 32.

[0043] This application provides a heat pump device, whose control mechanism 3 includes a mounting housing 31 and a control element 32. The mounting housing 31 has a mounting cavity 302 for independently mounting the control element 32. The mounting housing 31 ensures that the heat pump mechanism 2 and the control element 32 are properly separated, preventing the control element 32 from directly contacting the leaked refrigerant in case of failure, which could lead to refrigerant combustion or explosion, thus reducing potential safety risks. At the same time, by installing a fan assembly 4 inside the casing to drive the gas flow, the operation of the fan assembly 4 can drive the gas inside the casing and the mounting cavity 302 to flow towards the air outlet 105 and increase the gas flow rate and velocity. On the one hand, this allows the heat pump mechanism 2 and the control element 32 to obtain better heat dissipation, which is beneficial to extending the service life and improving the working efficiency of the device. On the other hand, the airflow can also promptly diffuse any accidentally leaked refrigerant inside the casing to the outdoor environment, preventing the refrigerant from accumulating inside the device and further reducing the risk of fire or even explosion.

[0044] like Figures 2 to 5As shown, in addition to the features of the above embodiments, this embodiment further includes: a water collection tray assembly 5, which is disposed in the inner cavity of the chassis. The water collection tray assembly 5 divides the inner cavity of the chassis into a first cavity 101 and a second cavity 102. The side wall of the first cavity 101 is provided with a first air inlet 103 and an air outlet 105. The water collection tray assembly 5 is provided with a first air duct housing 6. The second cavity 102 and the mounting cavity 302 are respectively connected to the second cavity 102 through the first air duct housing 6. The evaporator 22 is disposed in the first cavity 101. The water collection tray assembly 5 is disposed opposite to the evaporator 22 to receive the condensate flowing down from the evaporator 22. At least one of the compressor, condenser 21 and throttling device is disposed in the second cavity 102. The fan assembly 4 is disposed at the air outlet 105. The fan assembly 4 is used to drive the air in the first air inlet 103, the mounting cavity 302 and the second cavity 102 into the first cavity 101 and out through the air outlet 105. By adopting the above structure, the internal cavity of the chassis is divided into a first cavity 101 and a second cavity 102 using a water collection tray, which facilitates the reasonable arrangement and installation of the various components of the heat pump mechanism 2. The evaporator 22 is located in the first cavity 101, and the water collection tray assembly 5, positioned below the evaporator 22, effectively collects the condensate flowing down from the evaporator 22, preventing the compressor and other components from malfunctioning due to water contact. Furthermore, the fan assembly 4 is located at the air outlet 105. When the fan assembly 4 is working, it simultaneously creates a negative pressure within the first cavity 101, thereby rapidly drawing the high-temperature gas from the mounting cavity 302 and the second cavity 102 to the outside through the first cavity 101. The first cavity 101 is equipped with a first air inlet 103, through which outdoor air enters the first cavity 101, allowing the evaporator 22 to have more complete contact with the air. This allows the liquid refrigerant in the low-pressure section of the evaporator 22 to better absorb heat from the surrounding air and evaporate again, completing the transformation from liquid to gas.

[0045] like Figure 3 , Figures 5 to 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting housing 31 has a mounting wall 311, and control elements 32 and heat dissipation components 7 are respectively provided on both sides of the mounting wall 311. Specifically, the mounting wall 311 is made of metal material, and the control elements 32 and heat dissipation components 7 are respectively provided on opposite sides of the mounting wall 311, so that the heat generated by the control elements 32 can be quickly transferred to the heat dissipation components 7 through the mounting wall 311 to improve the cooling rate.

[0046] like Figure 3 , Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting housing 31 is disposed in the second cavity 102, the side wall of the second cavity 102 is provided with a second air inlet 104, the second air inlet 104 is connected to the side of the mounting cavity 302 away from the first air duct housing 6, the heat dissipation assembly 7 is located in the second cavity 102, and the heat dissipation assembly 7 is disposed opposite to the first air inlet end 611 of the first air duct housing 6. By adopting the above structure, the control mechanism 3, located in the second cavity 102, can better provide protection and simplify the structure of the first air duct housing 6, making installation more convenient. When the fan assembly 4 is working, it will drive the air at the second air inlet 104 into the mounting cavity 302 and flow through the first air duct housing 6 to the first cavity 101 and the air outlet 105 to be discharged outward. In addition, the heat dissipation assembly 7 is located in the second cavity 102 and is positioned opposite to the first air inlet 611 of the first air duct housing 6. Thus, the airflow flowing into the first air inlet 611 in the second cavity 102 can quickly carry away the heat absorbed by the heat dissipation assembly 7, effectively ensuring the heat dissipation effect of the heat dissipation assembly 7 and the control element 32.

[0047] like Figures 5 to 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the side wall of the first air inlet 611 is provided with a clearance opening 601, and the side wall of the first air inlet 611 with the clearance opening 601 is connected to the mounting wall 311 and encloses it to form an accommodating space, in which at least a portion of the heat dissipation component 7 is located. By adopting the above structure, the connection between the first air inlet 611 and the mounting wall 311 can help with the positioning and installation of the first air duct housing 6, and at least a portion of the heat dissipation component 7 will be installed in the first air duct housing 6, which can make the structure more compact and is conducive to increasing the airflow velocity at the heat dissipation component 7.

[0048] like Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the heat dissipation assembly 7 includes a first heat sink 71 and a second heat sink 72, and the first heat sink 71 and the second heat sink 72 are distributed along the air intake direction of the first air intake end 611. Specifically, the control element 32 includes a main control board 321, a compressor drive board 322, a fan drive board 323, and a reactor 324. The main control board 321 is electrically connected to the compressor drive board 322, the fan drive board 323, and the reactor 324, respectively. The first heat sink 71 and the compressor drive board 322 are respectively disposed on both sides of the mounting wall 311, and the second heat sink 72 and the reactor 324 and / or the fan drive board 323 are respectively disposed on both sides of the mounting wall 311. The compressor drive board 322 and the reactor 324 are the main heat sources of the control mechanism 3, and the fan drive board 323 is the secondary heat source. By positioning and installing the control element 32 according to the positions of the first radiator 71 and the second radiator 72 respectively to exchange heat, the heat dissipation efficiency of the control mechanism 3 can be effectively improved.

[0049] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first radiator 71 and the second radiator 72 are finned radiators, made of metal materials such as aluminum alloy, and the shape of the fins can be flat, corrugated, or concave-convex, etc., and their main function is to increase the surface area of ​​the radiator and improve the heat dissipation effect.

[0050] like Figure 3 , Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water tray assembly 5 is provided with a through hole connecting the first cavity 101 and the second cavity 102; the first air duct housing 6 includes a first housing 61, which is disposed in the second cavity 102; the first housing 61 includes a first air inlet end 611, a second air inlet end 612, and an air outlet end 613; the first air inlet end 611 communicates with the second cavity 102; the second air inlet end 612 communicates with the mounting cavity 302; and the air outlet end 613 communicates with the first cavity 101 through the through hole. By adopting the above structure, by connecting the single integrated first housing 61 to the water tray assembly 5 and the mounting housing 31 respectively, the communication between the first cavity 101 and the second cavity 102 and the mounting cavity 302 can be completed simultaneously, simplifying installation.

[0051] like Figures 2 to 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first air duct housing 6 also includes a second housing 62, which is disposed in the first cavity 101. The air inlet of the second housing 62 is connected to the air outlet 613 of the first housing 61 through a through hole, and the air outlet of the second housing 62 extends away from the second cavity 102 and is connected to the first cavity 101. By setting the second housing 62 so that the air outlet of the second housing 62 is higher than the water tray assembly 5, it can prevent the condensate dripping from the evaporator 22 from accidentally entering the second cavity 102 or the mounting cavity 302 through the through hole of the water tray assembly 5, thus avoiding malfunctions caused by water contact with components such as the compressor and control element 32.

[0052] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the air outlet end of the second housing 62 is bent away from the adjacent evaporator 22. By setting the air outlet end of the second housing 62 away from the adjacent evaporator 22, on the one hand, a shield can be formed above the air outlet end of the second housing 62, thereby reducing the fall of dust or foreign objects under gravity; on the other hand, it can further prevent the airflow flowing in from the first air inlet 103 from carrying away the condensate on the evaporator 22 and blowing it into the air outlet end of the second housing 62.

[0053] like Figure 3 , Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first air passage 301 and a second air passage 303 are respectively provided on opposite sides of the mounting housing 31; the side wall of the mounting housing 31 with the second air passage 303 is perpendicular to the mounting wall 311; the second air inlet 104, the first air passage 301, the mounting cavity 302, the second air passage 303, and the first air inlet end 611 are sequentially connected. By adopting the above structure, the first air inlet end 611 and the second air inlet end 612 are respectively provided on the perpendicularly arranged side walls of the mounting housing 31, which can help reduce the size of the mounting housing 31 and make it easier to arrange the control element 32 and the corresponding heat sink on the corresponding sides of the mounting wall 311.

[0054] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further includes a second air duct housing 8. The inner wall of the second cavity 102 is connected to the mounting housing 31 through the second air duct housing 8. The second air duct housing 8 connects the second air inlet 104 and the first air outlet 301. By adopting the above structure, the airflow at the second air inlet 104 can be effectively guided to flow quickly into the mounting cavity 302 through the first air outlet 301. At the same time, using the second air duct housing 8 also helps to reduce the size of the mounting housing 31.

[0055] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first air vent 301 is provided with an air inlet grille.

[0056] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second air vent 303 is provided with an air outlet grille.

[0057] like Figure 3 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further includes a refrigerant sensor 9, which is disposed in the inner cavity of the chassis. The refrigerant sensor 9 is communicatively connected to the control mechanism 3 and is used to detect the refrigerant status of the heat pump mechanism 2 in real time. By detecting the refrigerant concentration in the second cavity 102 in real time through the refrigerant sensor 9, the start-up status can be determined, and the normal operation of the heat pump device can be controlled. This effectively prevents the combustion or even explosion of flammable and explosive refrigerant, ensuring that the heat pump device can operate normally, stably, and safely.

[0058] In addition to the features of the above embodiments, this embodiment further specifies that: the heat pump mechanism 2 includes a compressor, a four-way valve, a condenser 21, a filter, a throttling device, and an evaporator 22 connected in sequence via pipelines. The evaporator 22 is connected to the four-way valve via pipelines, and a gas-liquid separator is also connected to the four-way valve. The gas-liquid separator is connected to the compressor. By adopting the above structure, when the heat pump device is working, the compressor discharges high-temperature and high-pressure gaseous refrigerant, which enters the condenser 21 through the four-way valve. The high-temperature and high-pressure gas is cooled and condensed into a high-pressure liquid by a low-temperature heat source, such as cooling water, in the condenser 21. The low-temperature heat source heats up due to heat absorption, thus achieving the function of heating water or providing heating. The refrigerant then enters the evaporator 22 through the throttling device, which plays a role in reducing pressure and throttling. The refrigerant absorbs heat from the outside air in the evaporator 22 and becomes gaseous refrigerant, which then enters the gas-liquid separator and returns to the compressor suction port, thus repeating the cycle.

[0059] In addition to the features of the above embodiments, this embodiment further specifies that: the compressor has a discharge pipe, and an oil separator is provided on the discharge pipe. The oil separator is connected to the compressor via a return pipe to send the separated oil back into the compressor. Separating the lubricating oil through the oil separator ensures good lubrication of the working components inside the compressor, reduces wear, and thus extends the compressor's service life. At the same time, it prevents excessive lubricating oil from entering the system, preventing lubricating oil from accumulating inside the heat exchanger and affecting heat exchange efficiency.
