The steam oven is an electric appliance with two heating functions of steam and baking, and generally comprises a box body, a box door, a heating pipe and a steam generating device, wherein the box door is in sealing fit with the box body, a cooking cavity is defined in the box body, and steam generated by the steam generating device is led into the cooking cavity for steam baking. At present, a steam oven on the market adopts a double-fan-blade system for heat dissipation, in the related art, two fan blades are arranged at intervals along the central line direction of a driving shaft of a heat dissipation motor, one fan blade is used for heat dissipation of a cooking cavity, and one fan blade is used for heat dissipation of the motor, however, the two fan blades are continuously installed on the driving shaft of the heat dissipation motor, and the structure needs a large space, so that the overall height of the steam oven is higher, and the occupied space of a machine is larger.
For this reason, as shown in fig. 1 to 3, the heat dissipation structure of the steam oven provided by the present utility model comprises a heat dissipation motor 100, a wind scooper 300, a housing 400 and a heat dissipation fan 410, wherein a cooking cavity 200 is arranged in the steam oven, the wind scooper 300 covers the opening of the cooking cavity 200, the heat dissipation motor 100 is arranged above the cooking cavity 200 and is installed on the wind scooper 300, the heat dissipation motor 100 is used for dissipating heat to the cooking cavity 200, the housing 400 is covered on the heat dissipation motor 100, and the heat dissipation motor 100 is prevented from being exposed. Specifically, the driving shaft 110 of the heat dissipation motor 100 is fixedly provided with the heat dissipation fan blade 111, the heat dissipation fan blade 111 is disposed in the air guide cover 300, in addition, one end of the air guide cover 300 is communicated with the cooking cavity 200, and the other end extends outwards, so that the heat dissipation fan blade 111 is driven by the heat dissipation motor 100 to guide hot air in the cooking cavity 200 out of the steam oven. Further, a heat radiation fan 410 is installed at a side wall of the housing 400, and the heat radiation fan 410 is used for radiating heat to the heat radiation motor 100. It should be noted that, the heat dissipation motor 100 is provided with a single heat dissipation fan 111 to dissipate heat of the cooking cavity 200, and the heat dissipation fan 410 is provided on the side wall of the housing 400 to dissipate heat of the heat dissipation motor 100; on the one hand, the length of the driving shaft 110 of the heat dissipation motor 100 is effectively reduced, on the other hand, the driving shaft 110 of the heat dissipation motor 100 is changed into a single fan blade from double fan blades, so that the load of the heat dissipation motor 100 is reduced, and the number of silicon steel sheets of the heat dissipation motor 100 can be reduced, so that the heat dissipation motor 100 with smaller specification is selected, the product height of the heat dissipation motor 100 is lower, the overall height of a machine is reduced, and the space utilization rate is improved. In some embodiments, the top height of the cooling fan 410 is less than or equal to the top height of the cooling motor 100, so that the height of the housing 400 depends on the top height of the cooling motor 100, effectively reducing the overall height of the machine. Specifically, the heat radiation fan 410 is disposed opposite to the heat radiation motor 100, and preferably radiates heat to the heat radiation motor 100.
In some embodiments of the present utility model, as shown in fig. 1 and 3, the heat pipe 210 is installed in the air guide cover 300, the heat pipe 210 is used for heating the cooking cavity 200, and the heat dissipation fan blade 111 is located above the heat pipe 210, and can better cooperate with the heat pipe 210 to blow hot air. Such as hot air generated from the heating tube 210, is blown into the cooking cavity 200. In addition, after the steam oven is used, the heating tube 210 stops heating, but the heating tube 210 is at a high temperature and still heats the air around the heating tube 210, at this time, the heat dissipation fan blade 111 is located above the heating tube 210 and operates, so that the hot air generated by the waste heat of the heating tube 210 can be directly led out and can not flow into the cooking cavity 200, and therefore, the heat dissipation effect after the steam oven is cooked is better. Specifically, the heat pipes 210 are arranged around the center line of the heat dissipation fan blade 111, so that the rotation of the heat dissipation fan blade 111 can be better adapted, specifically, a circular structure is formed when the heat dissipation fan blade 111 rotates, and the annular heat pipes 210 can be better acted on.
In some embodiments of the present utility model, as shown in fig. 2, the air guiding cover 300 is provided with an air outlet pipe 310, the air outlet pipe 310 is located outside the outer cover 400, and the air outlet pipe 310 and the cooling fan 410 are respectively located at adjacent sides of the outer cover 400, so that a hot air outlet in the cooking cavity 200 can be distinguished from an air outlet of the cooling fan 410. Since the temperature of the hot air in the cooking cavity 200 is high, there is a risk of scalding the user, but the temperature of the air flow outputted from the heat radiation fan 410 is not high, and the risk is low. In another embodiment of the present utility model, the air outlet pipe 310 and the cooling fan 410 are located on the same side (not shown) of the housing 400, so that the hot air output positions are unified on one side, and the requirements of different machine installation positions are met, for example, in a kitchen, the steam oven is placed on the side of the refrigerator, and at this time, if the air outlet on the side of the steam oven is sprayed to the refrigerator, the water is easily condensed on the outer wall of the refrigerator, and there is a safety hazard.
In some embodiments of the present utility model, as shown in fig. 1 and 2, the air outlet pipe 310 is provided with an air outlet channel 311, and the air outlet channel 311 extends along a vertical direction to guide hot air upwards, so that when the steam oven is installed close to a wall, hot steam is not sprayed to the wall to condense out water, thereby avoiding polluting the kitchen environment.
In some embodiments of the present utility model, as shown in fig. 1 and 4, the air guide housing 300 is mounted with a sealing ring 320, the sealing ring 320 is located at a side of the heat dissipation fan 111 facing away from the cooking cavity 200, and the sealing ring 320 is disposed around the driving shaft 110 of the heat dissipation fan 111. By blocking the cooking cavity 200 by the sealing ring 320, the air flow in the cooking cavity 200 does not flow to the heat dissipation motor 100 to damage the heat dissipation motor 100. Further, the bearing 321 is installed in the middle of the sealing ring 320, and the driving shaft 110 of the heat dissipation motor 100 is inserted into the inner ring of the bearing 321, so that the rotation of the heat dissipation fan blade 111 is smoother.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
