The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

The following describes in detail the structure of the heating apparatus provided in the embodiment of the present application with reference to fig. 1 to 8.

As shown in fig. 1 and fig. 4, the embodiment of the application provides a heating device, which includes a housing 100, a mixed-flow fan 200, a heating element 300 and a reversing assembly 400, wherein the mixed-flow fan 200, the heating element 300 and the reversing assembly 400 are all disposed in a cavity 110 of the housing 100, and the cavity 110 of the housing 100 can be used for installing the mixed-flow fan 200, the heating element 300 and the reversing assembly 400 and form protection. In addition, the casing 100 is provided with an air inlet 120, an air exchange air outlet 130 and a warm air outlet 140 which are communicated with the cavity 110; the air inlet 120 and the warm air outlet 140 communicate with the indoor environment, and the ventilation outlet 130 communicates with the outdoor environment. Meanwhile, the mixed flow fan 200 is arranged close to the air inlet 120, and the cavity 110 comprises an air outlet channel 112 positioned at one side of the mixed flow fan 200 away from the air inlet 120; the mixed flow fan 200 has an air inlet side and an air outlet side, the air inlet side of the mixed flow fan 200 faces the air inlet 120, the air outlet side of the mixed flow fan 200 faces the air outlet channel 112, and the air flow entering from the air inlet 120 can be conveyed into the air outlet channel 112 under the driving of the mixed flow fan 200.

The air outlet channel 112 includes an air exchanging channel 112A and a warm air channel 112B, which are arranged in parallel, and air flow in the air exchanging channel 112A can flow out from the air exchanging outlet 130; the warm air passage 112B communicates with the warm air outlet 140, so that the air flow in the warm air passage 112B can flow out from the warm air outlet 140; the heating element 300 is located in the warm air channel 112B, and the heating element 300 is capable of heating the air flow in the warm air channel 112B. The connection end 430 of the reversing assembly 400 is connected to the housing 100 far away from the ventilation air outlet 130, and the connection end 430 of the reversing assembly 400 is far away from the ventilation air outlet 130, so that when air flows out from the ventilation air outlet 130, the reversing assembly 400 does not block the air flow, and smooth outflow of the air flow is ensured.

Specifically, the reversing assembly 400 is movably connected with respect to the housing 100 and has a first state and a second state; as shown in fig. 1-3, the reversing assembly 400 is in a first state, and as shown in fig. 4-6, the reversing assembly 400 is in a second state.

When the reversing assembly 400 is in the first state, the reversing assembly 400 seals the air inlet 120 from communicating with the warm air outlet 140, and the air flows through the mixed flow fan 200 into the air exchanging channel 112A and flows out of the housing 100 through the air exchanging outlet 130. The ventilation air outlet 130 is in communication with the external environment, and the heating device is capable of delivering air from the indoor environment to the external environment, and at this time, the heating device is in a ventilation mode.

When the reversing assembly 400 is in the second state, the reversing assembly 400 seals the air inlet 120 from communicating with the air exchanging outlet 130, and the air flow enters at least the warm air channel 112B through the mixed flow fan 200, is heated by the heating element 300, and flows out of the housing 100 through the warm air outlet 140. The warm air outlet 140 is communicated with the indoor environment, and the heating device can heat the air in the indoor environment and then re-convey the air to the indoor environment, so that the temperature of the indoor environment is raised, and at the moment, the heating device is in a warm air mode. It should be noted that, the air flow may first enter the air exchanging channel 112A through the mixed flow fan 200, then enter the warm air channel 112B through the air exchanging channel 112A, and the air flow path is shown in fig. 5; alternatively, the air flow may directly enter the warm air channel 112B via the mixed flow fan 200, and the air flow path is shown in fig. 6.

Thus, by switching the operating state of the reversing assembly 400, the heating appliance can be brought into a ventilating mode or a warm air mode. The heating equipment provided by the application has few component parts, and the mixed flow fan 200 is arranged in the shell 100, so that the heating equipment has a compact structure and small occupied volume. In addition, as the mixed flow fan 200 is adopted in the heating equipment, the air outlet speed and the air outlet quantity of the mixed flow fan 200 are large, so that the air outlet speed and the air outlet quantity of the air exchanging air outlet 130 and the warm air outlet 140 are increased, and the air outlet is smoother. In addition, since the connection end 430 of the reversing assembly 400 is connected to the housing 100 far away from the air exchanging outlet 130, the reversing assembly 400 does not shade the air exchanging outlet 130, so that the air outlet of the air exchanging outlet 130 is smooth, and the air outlet of the air exchanging outlet 130 is further ensured.

As shown in fig. 7 and 8, the mixed flow fan 200 includes a casing 210, an impeller 220, and a flow guide 230, wherein the impeller 220 is disposed in the casing 210, and the flow guide 230 is disposed on the air outlet side of the impeller 220. It can be appreciated that the impeller 220 may be rotatably disposed inside the housing 210, and the air flow in the housing 210 is driven by rotation, so that the air flow generated by the impeller 220 may be guided by the guide member 230, so as to implement dynamic-static pressure conversion, improve the smoothness of the air outlet, and improve the air outlet efficiency of the impeller 220. The guide piece 230 includes a guide vane 231, the guide vane 231 includes a first guide portion 2311 and a second guide portion 2312, the first guide portion 2311 and the second guide portion 2312 are connected along an air outlet direction of the mixed flow fan 200, the first guide portion 2311 extends in an arc shape relative to the first direction, and the second guide portion 2312 extends in an arc shape relative to the second direction.

The surfaces of the first flow guiding portion 2311 and the second flow guiding portion 2312 may be curved surfaces, the projection of the first flow guiding portion 2311 in the first direction is arc-shaped, the projection of the second flow guiding portion 2312 in the second direction is arc-shaped, when the airflow flows from the impeller 220 to the guide vane 231, the airflow passes through the first flow guiding portion 2311 and then passes through the second flow guiding portion 2312, so that smooth output of the airflow is achieved. The first direction is the X direction in fig. 8, and the second direction is the Y direction in fig. 8. Specifically, the first direction may be a rotation axis of the impeller 220, the second direction is perpendicular to the first direction, that is, the X direction is a rotation axis of the impeller 220, the Y direction is a rotation radial direction of the impeller 220, and the X direction is perpendicular to the Y direction.

In the embodiment of the present application, as shown in fig. 1, the housing 100 includes a housing wall 150 and a partition 160, the housing wall 150 encloses a cavity 110, and the partition 160 is connected to the housing wall 150; the shell wall 150 is provided with an air inlet 120, an air exchanging air outlet 130 and a warm air outlet 140 which are communicated with the cavity 110. Meanwhile, the ventilation channel 112A and the warm air channel 112B are partitioned by a partition 160, and the partition 160 may be a thin plate.

So configured, the presence of the partition 160 can separate the ventilation channel 112A from the warm air channel 112B, thereby facilitating the adjustment of the airflow path in the air outlet channel 112.

Further, as shown in fig. 1 to 6, the warm air channel 112B has a communication port 500, and the reversing assembly 400 is disposed near the communication port 500. When in the first state, the reversing assembly 400 seals the communication port 500, and air flows into the air exchanging channel 112A through the mixed flow fan 200 and flows out of the housing 100 through the air exchanging outlet 130, as shown in fig. 2. When in the second state, the reversing assembly 400 opens the communication port 500, and the air flows through the mixed flow fan 200 at least into the warm air channel 112B, and flows out of the housing 100 through the warm air outlet 140 after being heated by the heating element 300, as shown in fig. 5.

So configured, by adjusting the reversing assembly 400, the communication port 500 is blocked or opened, thereby facilitating the adjustment of the flow path of the airflow in the air outlet passage 112.

In one embodiment, the partition 160 is provided with a through-opening forming the communication port 500. So configured, when the reversing assembly 400 is in the first state, the air flow cannot flow into the warm air channel 112B through the through-opening; when the reversing assembly 400 is in the second state, the air flow can flow into the warm air channel 112B via the communication port 500. Specifically, the through-hole may be located at the middle of the partition 160 in the extending direction of the partition 160. So arranged, when the through-hole is located in the middle of the partition 160, the ventilation passage 112A can communicate with the warm air passage 112B through the through-hole.

In another embodiment, a gap is provided between one end of the partition 160 and the case wall 150, the gap forming the communication port 500. Specifically, as shown in fig. 6, the reversing assembly 400 is in the second state, the communication port 500 formed by the gap is located at the end of the partition 160 near the mixed flow fan 200, at this time, the air flows through the mixed flow fan 200, and then the air can directly enter the warm air channel 112B from the communication port 500. Alternatively, as shown in fig. 5, the reversing assembly 400 is in the second state, the communication port 500 formed by the gap is located at one end of the partition 160 away from the mixed flow fan 200, and at this time, the air flow enters the air exchanging channel 112A through the mixed flow fan 200, and then enters the warm air channel 112B through the communication port 500 from the air exchanging channel 112A.

By this arrangement, the communication port 500 can be formed simply by the cooperation of the partition 160 and the case wall 150, and the structure is simple.

When the reversing assembly 400 is in the first state, the moving member 420 seals the communication port 500, and the air flows into the air exchanging channel 112A through the mixed flow fan 200 and flows out of the housing 100 through the air exchanging outlet 130, as shown in fig. 2. When the reversing assembly 400 is in the second state, the moving member 420 opens the communication port 500, and the air flows through the mixed flow fan 200 at least into the warm air channel 112B, and flows out of the housing 100 through the warm air outlet 140 after being heated by the heating member 300, as shown in fig. 5.

By the arrangement, the air inlet direction of the air inlet 120 and the air outlet direction of the air exchanging air outlet 130 can be selected according to actual installation conditions, so that actual installation requirements are met.

In the embodiment of the present application, as shown in fig. 1, the housing 100 is long, and the housing 100 extends in the same direction. The heating equipment is also of a long strip shape, so that the structure is more compact; meanwhile, the casing 100 is long, so that the air outlet channel 112 is prolonged, and the air flow can be fully accelerated in the air outlet channel 112, thereby improving the air outlet speed of the air outlet.
