[0042] like Figures 1 to 7 As shown, according to an embodiment of this application, a heating, ventilation and air conditioning (HVAC) device 100 is proposed, which includes a water tank assembly 10 and a heat pump assembly 20.

[0043] In the water tank assembly 10, a water tank 11 for storing water is included. In the heat pump assembly 20, a filter 22 and a housing 21 are included, the housing 21 is fixedly installed on the top of the water tank 11, a containing space is enclosed between the housing 21 and the water tank 11, the housing 21 includes a top cover 211 and an installation opening 2121, the top cover 211 is oppositely arranged with the water tank 11, an air inlet 2111 and an air outlet 2112 are formed on the top cover 211, the air inlet 2111 and the air outlet 2112 are spaced apart on the top cover 211, and the containing space is respectively connected with the outside through the air inlet 2111 and the air outlet 2112. The filter 22 is connected with the top cover 211 and can be detachably connected with the top cover 211, and on the outside of the heating and ventilation equipment 100, the filter 22 can be disassembled at the position of the installation opening 2121 of the housing 21.

[0044] The air flow entering the containing space through the air inlet 2111 needs to pass through the filter 22 for filtration to filter out impurities (dust or debris, etc.) carried in the air flow. After being filtered by the filter 22, the air flow enters the containing space and exchanges heat with the functional components (such as the compressor and the heat exchanger, etc.) of the heat pump assembly 20, and the air flow after heat exchange is discharged through the air outlet 2112.

[0045] When cleaning the filter 22, the filter 22 is separated from the top cover 211 at the position of the installation opening 2121 and taken out through the position of the installation opening 2121, and when the filter 22 is cleaned, the filter 22 is reconnected with the top cover 211 after passing through the installation opening 2121. According to the heating and ventilation equipment 100 of the present application, when the filter 22 is cleaned, the corresponding pipeline does not need to be disassembled, thereby effectively improving the convenience of cleaning the filter 22, and further improving the user experience.

[0046] It should be understood that in the present application, the air inlet 2111 refers to the position at which the external air flow can enter the containing space, and the air outlet 2112 refers to the position at which the air flow in the containing space can leave the containing space.

[0047] In addition, the filter 22 cooperates with at least the top cover 211 means that when the filter 22 is fixed in the containing space, the filter 22 can only cooperate with the top cover 211, or the filter 22 cooperates with other components in addition to the top cover 211.

[0048] In addition, when the filter 22 is properly cooperated with the top cover 211, the filter 22 abuts on the side of the top cover 211 facing the water tank 11 and blocks the air inlet 2111, so that the air flow entering through the air inlet 2111 is first filtered by the filter 22, thereby improving the filtering effect of the air flow.

[0049] It should be noted that the heating and ventilation device 100 further comprises a heat exchanger arranged at a heat exchange position required in the room, the water tank 11 is connected with the heat exchanger through a pipeline, a water flow path is formed between the heat exchanger and the water tank 11, the water in the water tank 11 is circulated to the heat exchange position of the heat exchanger to perform heat exchange with the heat exchange position in the room, and the water after heat exchange is returned to the water tank 11 and performs heat exchange with the heat pump assembly 20.

[0050] The water tank assembly 10 further comprises a first heat exchanger for performing heat exchange on the water stored in the water tank 11, wherein the first heat exchanger can be arranged inside the water tank 11 or outside the water tank 11, and in this application, the first heat exchanger is preferably arranged inside the water tank 11.

[0051] The heat pump assembly 20 further comprises a compressor, a second heat exchanger and a fan, the compressor, the second heat exchanger and the fan are arranged in the containing space, the compressor, the first heat exchanger and the second heat exchanger are connected to form a closed refrigerant circulation path, under the driving of the compressor, the refrigerant performs heat exchange with the water at the position of the first heat exchanger to change the temperature of the water, and the refrigerant performs heat exchange with the air flow passing through the containing space at the position of the second heat exchanger to change the temperature of the refrigerant. The fan drives the air flow to enter the containing space through the air inlet 2111 and to leave the containing space through the air outlet 2112, and the second heat exchanger is arranged on the flow path of the air flow to better perform heat exchange with the air.

[0052] In some embodiments of the present application, as shown in Figure 1 In the shell 21, a side cover 212 is further arranged, the side cover 212 is a cylindrical structure and is connected to the top of the water tank 11, the top cover 211 is connected to the side cover 212, the two openings of the cylindrical side cover 212 are closed by the top cover 211 and the water tank 11, and the top cover 211, the side cover 212 and the water tank 11 jointly enclose the containing space.

[0053] Specifically, an air inlet pipe and an air outlet pipe are arranged outside the top cover 211, wherein the air inlet pipe is connected with the top cover 211 and communicates with the air inlet 2111 (the connection mode includes but is not limited to clamping or connecting through a connecting piece), the air outlet pipe is connected with the top cover 211 and communicates with the air outlet 2112 (the connection mode includes but is not limited to clamping or connecting through a connecting piece), and the air inlet pipe and the air outlet pipe respectively communicate with the outside. A first mesh cover 2113 is arranged at the air inlet 2111, and the first mesh cover 2113 separates the air inlet pipe from the containing space (the first mesh cover 2113 is used to block foreign matters such as mice to avoid foreign matters entering the containing space to cause failure of the heating and ventilation device 100), and a second mesh cover 2114 is arranged at the air outlet 2112, and the second mesh cover 2114 separates the air inlet pipe from the containing space (the second mesh cover 2114 is also used to block foreign matters such as mice to avoid foreign matters entering the containing space to cause failure of the heating and ventilation device 100).

[0054] The mounting port 2121 is arranged on the side cover 212, and the mounting port 2121 is parallel to the top cover 211. When the filter element 22 is disassembled, the filter element 22 passes through the mounting port 2121, so that the filter element 22 is disassembled in a direction parallel to the top cover 211, which is convenient to implement, thereby improving the convenience of disassembling the filter element 22.

[0055] It should be noted that the connection mode between the side cover 212 and the top of the water tank 11 includes but is not limited to clamping, welding, bonding or connecting through a connecting piece.

[0056] In addition, the connection mode between the top cover 211 and the side cover 212 includes but is not limited to clamping, welding, bonding or connecting through a connecting piece. As a preferred embodiment, a plurality of mounting holes 2115 are arranged on the top cover 211, and the plurality of mounting holes 2115 are arranged at intervals along the edge of the top cover 211. A plurality of fixing holes are arranged on the side cover 212 facing the top cover 211, and each mounting hole 2115 corresponds to one fixing hole. A screw is screwed through the mounting hole 2115 and screwed with the fixing hole, so that the top cover 211 and the side cover 212 are connected and fixed.

[0057] In some embodiments of the present application, as shown in Figure 1 In the arrangement direction of the housing 21 and the water tank 11, the first distance is between the top cover 211 and the mounting port 2121, and the second distance is between the water tank 11 and the mounting port 2121, wherein the first distance is less than the second distance.

[0058] It should be understood that the first distance refers to the minimum distance between the top cover 211 and the mounting port 2121, and the second distance refers to the minimum distance between the water tank 11 and the mounting port 2121.

[0059] Specifically, by setting the first distance and the second distance, the mounting port 2121 is arranged close to the top cover 211. In this way, the position of the mounting port 2121 is closer to the mounting position of the filter element 22, further improving the convenience of disassembling the filter element 22.

[0060] It should be noted that in the present application, the first distance can be specifically 0 cm, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm or 10 cm.

[0061] In some embodiments of the present application, as shown in Figures 4 to 5 , or Figures 6 to 7As shown, the filter 22 comprises a filter screen 222 and a support frame 221, the filter screen 222 is arranged on the support frame 221, the support frame 221 cooperates with the top cover 211, and the support frame 221 can be detached from the top cover 211. When the support frame 221 is installed in place on the top cover 211, the filter screen 222 is arranged opposite the air inlet 2111.

[0062] Specifically, the filter screen 222 is a flexible component and is prone to deformation under the impact of airflow. The filter screen is arranged on the support frame 221, and the support frame 221 supports the filter screen 222, thereby improving the structural strength of the filter screen 222, reducing the deformation of the filter screen 222 caused by airflow impact, and thereby improving the filtering effect of the airflow.

[0063] It should be noted that the support frame 221 is provided with a through hole, and the filter screen 222 is fixed on the support frame 221 and covers the through hole. When the support frame 221 is installed in place on the top cover 211, the through hole is coaxially arranged with the air inlet 2111, and the area of the through hole is greater than or equal to the area of the air inlet 2111, so that the airflow passing amount is not affected.

[0064] In addition, the connection mode between the filter screen and the support frame 221 includes but is not limited to bonding, clamping, or connecting through a connecting piece, etc.

[0065] In some embodiments of the present application, as shown in Figures 4 to 3 As shown, the top cover 211 comprises a first surface 2119, the first surface 2119 faces the accommodation space, and a cooperation structure 2116 is arranged on the first surface 2119, the cooperation structure 2116 is arranged on the side of the top cover 211 facing the accommodation space, wherein the cooperation structure 2116 is arranged on the outer side of the air inlet 2111, and the cooperation structure 2116 is arranged along the circumference of the air inlet 2111, and at least part of the circumferential edge of the support frame 221 cooperates with the cooperation structure 2116, and the circumferential edge of the support frame 221 can be separated from the cooperation structure 2116.

[0069] In addition, the mounting port 2121 is arranged opposite to the pulling direction of the support frame 221, so that the filter element 22 can enter or exit the containing space through the mounting port 2121.

[0070] In some embodiments of the present application, as shown in Figure 3 The matching structure 2116 includes a first limiting portion 21161, which is arranged on one side of the air inlet 2111.

The support frame 221 includes a first edge, which is embedded in the first guide groove 2117 and can slide in the extension direction of the first guide groove 2117 relative to the first guide groove 2117.

[0071] Specifically, the top cover 211 and the first limiting portion 21161 define the first guide groove 2117. The first guide groove 2117 is matched with the first edge of the support frame 221, so as to form a pulling structure, further improving the convenience of disassembling the filter element 22, and further improving the user experience.

[0075] In addition, the first guide groove 2117 and the second guide groove 2118 are arranged to cooperate on opposite sides of the support frame 221, thereby improving the fixing strength between the support frame 221 and the top cover 211, and further improving the stability of the filter element 22 after assembly, so that the filtering effect can be improved.

[0076] It should be pointed out that the second limiting portion 21162 is an L-shaped structure, one side wall of the L-shaped structure is connected with the first surface 2119 of the top cover 211, and the other side wall is arranged in parallel and spaced apart from the first surface 2119 of the top cover 211, and the first limiting portion 21161 of the L-shaped structure is enclosed with the top cover 211 to form the second guide groove 2118. The side of the second guide groove 2118 facing the mounting port 2121 is an open structure, which facilitates the insertion or exit of the second edge of the support frame 221 into or out of the second guide groove 2118.
