[0034] DETAILED DESCRIPTION

[0035] A heating and ventilation device is a mechanical device for adjusting temperature, which can be used for refrigeration or heating to make use of heat. The heating and ventilation device generally comprises a compressor, a condenser, a throttling valve and an indoor heat exchanger. Taking a heating mode as an example, the working process is as follows: low-temperature and low-pressure liquid refrigerant (for example, freon) first absorbs heat from a high-temperature heat source (for example, air at room temperature) in the indoor heat exchanger and vaporizes into low-pressure steam. Then, the refrigerant gas is compressed into high-temperature and high-pressure steam in the compressor, and the high-temperature and high-pressure gas exchanges heat with water in the condenser to condense into high-pressure liquid. The high-pressure liquid is throttled into low-temperature and low-pressure liquid refrigerant by a throttling element, and reenters the indoor heat exchanger. In this way, the water is heated through repeated circulation.

[0036] In the above heating and ventilation device, a refrigerant circuit and a water circuit are further provided. The refrigerant circuit is used for transmitting refrigerant, for example, a refrigerant circuit between the compressor and the condenser, a refrigerant circuit between the compressor and the indoor heat exchanger, etc. The water circuit is used for conveying water, for example, a water pipe connected to the water inlet end of the condenser, a water pipe connected to the water outlet end of the condenser, a water pipe connected to the water pump, etc. In the related art, the water circuit structure of the heating and ventilation device has many components and an unreasonable spatial layout, which leads to a large installation space, a large volume of the heating and ventilation device and difficult subsequent maintenance.

[0037] Therefore, the present application provides a new heating and ventilation device, which comprises a first partition plate and a water circuit assembly. The first partition plate is used to form a containing cavity for containing the water circuit assembly. The water circuit assembly comprises a heat exchanger, a water pump and a first electric control box. The heat exchanger is provided with a water flow path and a refrigerant flow path. The refrigerant flow path is used to communicate with a refrigerant circuit assembly. The water flow path communicates with the water pump. The first electric control box is installed on the first partition plate and located above the water pump and the heat exchanger. In this way, the first electric control box is staggered with the water pump and the heat exchanger, which helps to improve the compactness of the water circuit assembly structure, improve the space utilization rate, reduce the installation space and reduce the volume of the heating and ventilation device. On the other hand, the influence of water pump leakage and heat exchanger liquid leakage on the first electric control box can be reduced, and the wiring and arrangement of the first electric control box are facilitated.

[0038] The principles and characteristics of the present application are described below in conjunction with the accompanying drawings, and the examples are only used to explain the present application and not to limit the scope of the present application.

[0040] It should be first noted that in the embodiments of the present application, the orientation word "front" refers to the side provided with the fan air outlet cover, the orientation "back" is opposite to the orientation "front"; the orientation words "bottom" and "down" refer to the side facing the ground, and the orientation words "top" and "up" refer to the side away from the ground.

[0041] The heating and ventilation equipment of the embodiments of the present application can be used for heating and also can be used for cooling. The heating and ventilation equipment of the embodiments of the present application can be an air conditioner, a multi-connected central air conditioner, a heat pump equipment, a swimming pool machine, etc. The structure and functions of the heating and ventilation equipment of the embodiments of the present application will be further described below in combination with the drawings.

[0042] In combination with Figure 1 and Figure 2 , the embodiments of the present application provide a heating and ventilation equipment, which comprises a first partition plate 100 and a water circuit assembly 200, wherein the first partition plate 100 is used to form an accommodation cavity accommodating the water circuit assembly 200. The first partition plate 100 can form the accommodation cavity alone to accommodate the water circuit assembly 200, for example, the first partition plate 100 comprises a plurality of side plates which are enclosed to form the accommodation cavity; or the first partition plate 100 and other structures of the heating and ventilation equipment jointly enclose the accommodation cavity, for example, the first partition plate 100 and the shell of the heating and ventilation equipment jointly enclose the accommodation cavity.

[0043] The water circuit assembly 200 of the embodiments of the present application is used to transmit water, and the structure and functions of the water circuit assembly 200 will be described below in combination with Figure 3 and Figure 4 . The water circuit assembly 200 comprises a heat exchanger 210, a water pump 220 and a first electric control box 230.

[0044] The heat exchanger 210 is provided with a water flow path and a refrigerant flow path, the refrigerant flow path is used to communicate with the refrigerant circuit assembly 300 to realize refrigerant transmission, and the water flow path communicates with the water pump 220 to realize heat exchange between the water flow path and the refrigerant water path. The heat exchanger 210 can be a plate type water side heat exchanger, a sleeve type water side heat exchanger, etc. The fixing mode of the heat exchanger 210 is various, the heat exchanger 210 can be fixed on the first partition plate 100, and / or the heat exchanger 210 is fixed on the bottom plate of the heating and ventilation equipment. The fixing mode includes but is not limited to screw connection, clamping, etc.

[0045] The water pump 220 provides power for water flow, and the water pump 220 can be fixed on the first partition plate 100, or the water pump 220 is fixed on the bottom plate of the heating and ventilation equipment. The fixing mode includes but is not limited to screw connection, clamping, etc.

[0046] In some possible implementation manners, the water pump 220 is installed on the back side of the heat exchanger 210. In this way, the water pump 220 and the heat exchanger 210 are staggered to fully utilize the space, and the water pump 220 is located on the back side, so that the water inlet and outlet pipes can be arranged to pass through to the outside of the heating and ventilation equipment, thereby saving the pipes and reducing the cost.

[0047] The first electric control box 230 is installed on the first partition plate 100. For example, the first electric control box 230 is fixed on the first partition plate 100 in one or a combination of multiple manners such as screwing, clamping, hinging, and hinge connection. For example, the first electric control box 230 is clamped on the first partition plate 100. The first electric control box 230 is located above the water pump 220 and the heat exchanger 210. On one hand, the water pump 220 and the heat exchanger 210 have a large volume and a large size along the X-axis direction in the drawings, and the first electric control box 230 is arranged above the water pump 220 and the heat exchanger 210, thereby improving the compactness of the water circuit assembly 200 and improving the space utilization. On the other hand, the influence of water leakage of the water pump 220 and liquid leakage of the heat exchanger 210 on the first electric control box 230 can be reduced, and the wiring and arrangement of the first electric control box 230 are facilitated.

[0048] The structure and function of the first partition plate 100 in the embodiment of the present application will be described in detail below with reference to the drawings.

[0049] The first partition plate 100 in the embodiment of the present application includes a side plate body 110, a first fixing portion 120, and a second fixing portion 130. The first fixing portion 120 and the second fixing portion 130 are arranged at opposite ends of the side plate body 110. For example, the first fixing portion 120 is arranged at the front end of the side plate body 110, and the second fixing portion 130 is arranged at the rear end of the side plate body 110. Figure 3 The side plate body 110 is arranged on the YZ plane and serves as a partition plate. The first fixing portion 120 and the second fixing portion 130 provide mounting structures for components, and the side plate body 110, the first fixing portion 120, and the second fixing portion 130 jointly form a receiving cavity for receiving the water circuit assembly 200.

[0050] Optionally, the first fixing portion 120 and the side plate body 110 are two independent components, and the first fixing portion 120 is fixedly connected to the side plate body 110, for example, by screwing. Alternatively, the first fixing portion 120 and the side plate body 110 are integrally formed as one piece, for example, the front end of the side plate body 110 is bent to form the first fixing portion 120.

[0051] Optionally, the second fixing part 130 and the side plate body 110 are two independent parts respectively, and the second fixing part 130 and the side plate body 110 are fixedly connected, for example, the second fixing part 130 and the side plate body 110 are connected through screws. Alternatively, the second fixing part 130 and the side plate body 110 are integrally formed as an integral piece, for example, the rear end of the side plate body 110 is formed into the second fixing part 130 through a bending process.

[0052] Based on the above structure of the first partition plate 100, the first electric control box 230 is fixedly connected with the first fixing part 120 and / or the second fixing part 130, so that the first electric control box 230 can be fixedly connected with the first fixing part 120, or the first electric control box 230 is fixedly connected with the second fixing part 130, or the first electric control box 230 is fixedly connected with the first fixing part 120 and the second fixing part 130 at the same time, and the connection mode is flexible. When the first electric control box 230 is fixedly connected with the first fixing part 120 and the second fixing part 130 at the same time, the first electric control box 230 covers the part of the side plate body 110 above the heat exchanger 210, and the pipeline is arranged by using the space between the first electric control box 230 and the side plate body 110.

[0053] The first electric control box 230 of the embodiment of the application is fixedly connected with the first fixing part 120 and / or the second fixing part 130, so that there is a space between the first electric control box 230 and the side plate body 110, which facilitates the arrangement of the pipeline and further improves the compactness of the waterway assembly 200.

[0054] Based on the above structure of the first partition plate 100, the heat exchanger 210 is fixedly connected with the side plate body 110, for example, the heat exchanger 210 is fixed on the side plate body 110 through screws, and for another example, the heat exchanger 210 is clamped on the side plate body 110 through a clamping structure. In this way, the first fixing part 120 close to the heat exchanger 210 can be arranged only on the heat exchanger 210, without extending to the bottom of the side plate body 110, which reduces the volume of the first fixing part 120 while meeting the fixing requirements, and is beneficial to reducing the volume of the waterway assembly 200.

[0055] Based on the above structure of the first partition plate 100, the water pump 220 is fixedly connected with the side plate body 110, for example, the shell of the water pump 220 is connected with the side plate body 110 through screws, and for another example, the water pump 220 is fixed on the side plate body 110 through a support, a fixing plate or the like by using screws.

[0056] Continuing to refer to Figure 3 and Figure 4The first partition 100 also includes a support base 140 for supporting the heat exchanger 210. In this embodiment, the support base 140 is located at the bottom end of the side plate body 110. The support base 140 and the side plate body 110 can be integrally formed, for example, the bottom end of the side plate body 110 is formed by bending the support base 140; or, the support base 140 and the side plate body 110 are independent components, fixedly connected by screws, snap-fits, or other connection methods. This embodiment improves the stability and reliability of the heat exchanger 210 installation by providing the support base 140 to support the heat exchanger 210.

[0057] Combination Figure 3 and Figure 4 The first fixing part 120 includes a front end plate 121 and a first fixing plate 122. The front end plate 121 is connected to the side plate body 110. For example, the front side of the side plate body 110 is bent to form the front end plate 121. Another example is that the front side of the side plate body 110 is bent to form a first flange, and the front end plate 121 is bent to form a second flange. The second flange and the first flange are connected by screws. In this embodiment, the front end plate 121 is disposed perpendicular to the side plate body 110.

[0058] The first fixing plate 122 is connected to the front end plate 121. The first fixing plate 122 can be directly connected to the front end plate 121, or it can be indirectly connected to the front end plate 121. The first fixing plate 122 is perpendicular to the front end plate 121, and the first fixing plate 122 is parallel to and spaced from the side plate body 110.

[0059] In one possible implementation, the first fixing part 120 further includes a first connecting plate 123 and a second connecting plate 124; the end of the front end plate 121 facing away from the side plate body 220 is bent and extended toward the second fixing part 130 to form the first connecting plate 123, optionally, the first connecting plate 123 is perpendicular to the front end plate 121; the end of the first connecting plate 123 facing away from the front end plate 121 is bent and extended toward the side plate body 110 to form the second connecting plate 124, optionally, the second connecting plate 124 is perpendicular to the first connecting plate 123. The second connecting plate 124 is connected to the first fixing plate 122, thus the first fixing plate 122 is indirectly connected to the front end plate 121 through the first connecting plate 123 and the second connecting plate 124.

[0060] In order to improve the structural strength of the first fixing part 120, multiple reinforcing grooves are provided at the connection between the front end plate 121 and the first connecting plate 123, the connection between the first connecting plate 123 and the second connecting plate 124, and the connection between the second connecting plate 124 and the first fixing plate 122; the multiple reinforcing grooves are arranged at intervals along the vertical direction.

[0061] Combination Figure 2 and Figure 3The second connecting plate 124 is opposite to the first electric control box 230, specifically, the second connecting plate 124 is opposite to the front side of the first electric control box 230. In this way, the first electric control box 230 is not only protected, but also limited in installation. At this time, the first electric control box 230 can be wired from the bottom. Of course, when the second connecting plate 124 has a large gap with the front side of the first electric control box 230, the first electric control box 230 can also be wired from the front side.

[0062] Based on the structure of the first fixing part 120, the first electric control box 230 is fixedly connected with the first fixing plate 122, for example, the first electric control box 230 is connected with the first fixing plate 122 by clamping, screwing or the like. With respect to the double-layer plate structure of the second connecting plate 124 and the front end plate 121, the first electric control box 230 is connected with the first fixing plate 122, which is simple and convenient.

[0063] The first fixing part 120 of the embodiment of the application further comprises a support plate 125. The bottom end of the first fixing part 120 is bent and extended away from the side plate body 110 to form the support plate 125. Specifically, the bottom end of the first fixing plate 122 is bent and extended away from the side plate body 110 to form the support plate 125. The support plate 125 is used to support the first electric control box 230, so as to improve the stability and reliability of the installation of the first electric control box 230.

[0064] Continuing to refer to Figure 3 and Figure 4 The second fixing part 130 comprises a rear end plate 131 and a second fixing plate 132. The rear end plate 131 is connected with the side plate body 110, for example, the rear side edge of the side plate body 110 is bent to form the rear end plate 131. Further, for example, the rear side edge of the side plate body 110 is bent to form a connecting flange, and the rear end plate 131 is bent to form a fixed flange. The two fixed flanges are connected by screws. The rear end plate 131 of the embodiment of the application is perpendicular to the side plate body 110, and the rear end plate 131 is parallel to the front end plate 121 and has a gap. The space for accommodating the first electric control box 230 is formed by the front end plate 121, the side plate body 110 and the rear end plate 131.

[0065] The second fixing plate 132 is connected with the rear end plate 131. Optionally, the second fixing plate 132 and the rear end plate 131 are an integral piece. The second fixing plate 132 can be a flat plate perpendicular to the rear end plate 131, or a bent plate adapted to the rear end shape of the first electric control box 230. The second fixing plate 132 is fixedly connected with the first electric control box 230. In this way, the first electric control box 230 is fixedly connected with the first fixing plate 122 and the second fixing plate 132 respectively, and the connection mode is stable and reliable.

[0066] In some possible implementation manners, the second fixing plate 132 and / or the rear end plate 131 is provided with a clamping opening 1301, and the first electric control box 230 is provided with a buckle 231 that is clamped with the clamping opening 1301, so as to realize preliminary fixing and positioning of the first electric control box 230, and the first electric control box 230 is connected with the first fixing plate 122 through screws, and the connection mode is simple and stable and reliable.

[0067] The second fixing plate 132 of the embodiment of the application is fixedly connected with the first electric control box 230, and the second fixing plate 132 is arranged above the rear end plate 131; the rear end plate 131 extends to the bottom end of the side plate body 110, and the bottom of the rear end plate 131 is provided with a through hole, so that the water inlet and outlet pipe of the waterway assembly 200 extends to the outside of the first partition plate 100, and at this time, the rear end plate 131 plays a role of supporting the water inlet and outlet pipe.

[0068] Continuing to refer to Figure 3 and Figure 4 The waterway assembly 200 of the embodiment of the application further includes a first pipeline 240, the first pipeline 240 is in communication with the water flow path of the heat exchanger 210, the first pipeline 240 is located below the water pump 220, and the first pipeline 240 extends to the outside of the first partition plate 100. The first pipeline 240 is a straight pipeline, which is beneficial to reducing water inlet resistance.

[0069] The waterway assembly 200 of the embodiment of the application further includes a second pipeline 250 and a third pipeline 260, the second pipeline 250 is in communication with the water pump 220, and the second pipeline 250 extends to the outside of the first partition plate 100. One of the second pipeline 250 and the first pipeline 240 is used for water inlet, and the other is used for water outlet. The second pipeline 250 and the first pipeline 240 are arranged in an upper and lower interval, which is convenient for pipeline connection and arrangement.

[0070] The third pipeline 260 of the embodiment of the application is in communication with the water flow path of the heat exchanger 210 and the water pump 220.

[0071] In some possible implementation manners, the waterway assembly 200 is not provided with an electric heater, and specific reference is made to Figure 4The third pipeline 260 comprises a first pipe section 261, a second pipe section 262 and a third pipe section 263. In the embodiment, the first pipe section 261, the second pipe section 262 and the third pipe section 263 are one pipeline, and each pipe section is formed by bending arrangement. In this way, the number of connecting ports can be reduced, and the risk of water leakage can be reduced. The first pipe section 261 is connected to the second pipe section 262 and the water pump 220, and the third pipe section 263 is connected to the second pipe section 262 and the water flow path of the heat exchanger 210. The first pipeline 240, the water flow path of the heat exchanger 210, the third pipe section 263, the second pipe section 262, the first pipe section 261, the water pump 220 and the second pipeline 250 form a water flow channel. At this time, the second pipeline 250 can be a water outlet pipe, the first pipeline 240 can be a water inlet pipe, and the water pump 220 is arranged at the water outlet end of the water flow channel.

[0072] The first pipe section 261 and the third pipe section 263 are both located below the second pipe section 262. At this time, the second pipe section 262 is located at the top end of the entire water flow channel. Therefore, the second pipe section 262 is provided with an exhaust valve 2621 for exhausting the gas in the water flow channel.

[0073] In combination with Figure 2 and Figure 3 At least part of the third pipeline 260 and / or the exhaust valve 2621 is located in the space enclosed by the first electric control box 230 and the first partition plate 100. This can improve the compactness of the waterway assembly 200 and reduce the installation space.

[0074] In other possible implementations, in combination with Figure 3 The waterway assembly 200 further comprises an electric heater 270. The electric heater 270 is located above the heat exchanger 210 and is connected to the water flow path of the heat exchanger 210.
