Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to a cooling fan for a cooking device and a cooking device. Background Technology

[0002] Existing cooking appliances such as microwave ovens and steam ovens are generally small in capacity and low in power. However, as people's living standards continue to improve, small-capacity cooking appliances with low microwave power can no longer meet consumer needs. Consumers are gradually inclined to purchase multi-functional cooking appliances with large capacity, high microwave power, grilling functions, and infrared sensing functions.

[0003] However, these large-capacity, multi-functional cooking devices often have higher cooking temperatures and higher requirements for heat dissipation. In addition, the spatial distance between various components is relatively greater. This means that conventional fans in existing cooking devices often cannot meet the heat dissipation needs of multi-functional cooking devices, which is not conducive to ensuring the normal operation of various components. Utility Model Content

[0004] In view of this, the present invention aims to provide a cooling fan for a cooking device and a cooking device in order to solve the problem that conventional fans in the prior art cannot meet the heat dissipation requirements of multi-functional cooking devices.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A cooling fan for a cooking device includes a fan bracket, a fan assembly, and an infrared sensing assembly. The fan assembly is connected to the fan bracket, and the fan bracket includes an air guide cover. The fan assembly is disposed in the air guide cover, which completely surrounds the fan assembly 360° along its circumferential direction. An air inlet is provided on the side wall of the air guide cover, and the infrared sensing assembly is disposed in the air inlet.

[0007] Furthermore, the infrared sensing component includes a sensor bracket and an infrared sensor. The infrared sensor is connected to the sensor bracket, and the sensor bracket is detachably connected to the air guide cover at the air inlet. At least a portion of the structure of the infrared sensor is located on the windward side of the air inlet.

[0008] Furthermore, the air guide cover has a windproof side plate on the side of the air inlet away from the infrared sensing component.

[0009] Furthermore, the cooling fan includes a filter plate, and an assembly part is provided on the circumferential outer wall of the air guide shroud. The filter plate is detachably connected to the assembly part.

[0010] Furthermore, the assembly part includes a snap-fit ​​arm and a limiting stop plate, the outer edge of the filter plate abuts against the limiting stop plate, and the filter plate snaps into the snap-fit ​​arm.

[0011] Furthermore, the assembly part includes a stud, and the filter plate is connected to the stud by fasteners.

[0012] Furthermore, a gap is formed between the outer walls of the filter plate and the air guide shroud.

[0013] Furthermore, the outer wall of the air guide cover is provided with air holes, one end of which is connected to the inner cavity of the air guide cover and the other end is connected to the gap.

[0014] Furthermore, the fan assembly includes a motor and fan blades, the fan blades being connected to the output shaft of the motor; a fixing part is provided inside the air guide cover, and the motor is detachably connected to the fixing part.

[0015] A cooking appliance, including a cooling fan for the cooking appliance.

[0016] Compared with the prior art, the cooling fan and cooking device of the present invention have the following advantages:

[0017] The present invention relates to a cooling fan for a cooking device and a cooking device in general. By assembling the fan assembly using a fan bracket and fully enclosing the fan assembly with a wind guide cover, the air generated by the fan assembly can be effectively concentrated, increasing the airflow force and volume. This also allows the air blown out by the fan assembly to travel further, improving the cooling fan's heat dissipation capacity and effectively cooling various components to meet corresponding heat dissipation requirements.

[0018] In addition, the cooling fan of this application has an additional air inlet on the side wall of the air guide cover, and the infrared sensing component is placed in the air inlet. On the one hand, this helps to increase the air intake of the cooling fan and improve its heat dissipation capacity. On the other hand, the airflow can directly dissipate heat and cool the infrared sensing component during the air intake process, so as to further meet the heat dissipation requirements of the multi-functional cooking equipment. At the same time, the cooling fan integrates the assembly of the infrared sensing component, eliminating the need to set up an additional assembly position for the infrared sensing component in the cooking equipment, which helps to improve the integration of components.

[0027] The inventive concepts of this disclosure will be described below using terminology commonly used by those skilled in the art to convey the essence of their work to others skilled in the art. However, these inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments described herein.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The directional terms used in this invention, such as "front" and "back," can be referred to in the appendix. Figure 3 The coordinates are shown in the figure. The red line in the attached figure indicates the infrared sensing direction of the infrared sensor 122.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To address the problem that conventional fans in existing technologies cannot meet the heat dissipation requirements of multi-functional cooking equipment, this embodiment proposes a cooling fan for cooking equipment, as shown in the attached figure. Figure 1-5As shown, the cooling fan 1 includes a fan bracket 11, a fan assembly 14, and an infrared sensor assembly 12. The fan assembly 14 is connected to the fan bracket 11. The fan bracket 11 includes an air guide shroud 111. The fan assembly 14 is disposed in the air guide shroud 111. Along the circumferential direction of the fan assembly 14, the air guide shroud 111 completely surrounds the fan assembly 14 360°. An air inlet 112 is provided on the side wall of the air guide shroud 111, and the infrared sensor assembly 12 is disposed in the air inlet 112.

[0031] This application, while assembling the fan assembly 14 using the fan bracket 11, also fully surrounds the fan assembly 14 with a guide shroud 111. This effectively concentrates the airflow generated by the fan assembly 14, increasing the airflow force and volume, and allowing the airflow from the fan assembly 14 to travel further, thus improving the heat dissipation capacity of the cooling fan 1. This effectively dissipates heat from various components, meeting corresponding heat dissipation requirements. Furthermore, the cooling fan 1 of this application has an additional air inlet 112 on the side wall of the guide shroud 111, and the infrared sensor component 12 is placed in the air inlet 112. On the one hand, this increases the airflow of the cooling fan 1, improving its heat dissipation capacity. On the other hand, the airflow passing through the air inlet 112 directly dissipates and cools the infrared sensor component 12, further meeting the heat dissipation requirements of the multi-functional cooking equipment. At the same time, the cooling fan 1 integrates the assembly of the infrared sensor component 12, eliminating the need for an additional mounting position for the infrared sensor component 12 within the cooking equipment, which helps to improve the integration level of the components.

[0032] The infrared sensing assembly 12 includes a sensor bracket 121 and an infrared sensor 122. The infrared sensor 122 is connected to the sensor bracket 121. The sensor bracket 121 is detachably connected to the air guide cover 111 at the air inlet 112, such as by snap-fit ​​or fastener connection. At least a portion of the structure of the infrared sensor 122 is located on the windward side of the air inlet 112, allowing the airflow to directly contact the outer surface of the infrared sensor 122 during air intake, thereby achieving heat dissipation and cooling of the infrared sensor 122. More precisely, the fact that at least a portion of the structure of the infrared sensor 122 is located on the windward side of the air inlet 112 can be understood as follows: the projection of at least a portion of the structure of the infrared sensor 122 coincides with the projection of the air inlet 112 on the projection along the main air intake direction at the air inlet 112.

[0033] Based on this, the infrared sensing direction of the infrared sensor 122 can be parallel to or not parallel to the orientation of the air inlet 112. It is recommended to determine this according to the actual setting position of the infrared sensor 122 and the application requirements.

[0034] The air guide cover 111 has a windproof side plate 113 on the side of the air inlet 112 away from the infrared sensing component 12. With the windproof side plate 113, when the airflow passes through the air inlet 112, it is blocked by the windproof side plate 113, so that more airflow flows into the air inlet 112 from the side closer to the infrared sensing component 12. Correspondingly, the airflow near the infrared sensing component 12 is increased, so as to further improve the heat dissipation and cooling effect on the infrared sensing component 12.

[0035] Regarding the connection between the fan bracket 11 and the fan assembly 14, the fan assembly 14 includes a motor 141 and a fan blade 142, and the fan blade 142 is connected to the output shaft of the motor 141; a fixing part 116 is provided inside the air guide cover 111, and the motor 141 is detachably connected to the fixing part 116. Preferably, the motor 141 and the fixing part 116 are connected by fasteners.

[0036] The cooling fan 1 includes a filter plate 13. An assembly part 114 is provided on the circumferential outer wall of the air guide cover 111. The filter plate 13 is detachably connected to the assembly part 114. By also mounting the filter plate 13 on the cooling fan 1, on the one hand, the filter plate 13 can be cooled by the airflow during the operation of the fan assembly 14. On the other hand, the cooling fan 1 integrates the assembly of the filter plate 13, eliminating the need to set up an additional assembly position for the filter plate 13 in the cooking equipment, and further improving the integration of the components.

[0037] Preferably, the assembly part 114 includes a snap-fit ​​arm 1141 and a limiting stop plate 1142. The outer edge of the filter plate 13 abuts against the limiting stop plate 1142, and the filter plate 13 snaps into the snap-fit ​​arm 1141, thereby realizing the snap-fit ​​assembly of the filter plate 13 and the air guide shroud 111. Furthermore, to further improve the assembly reliability of the filter plate 13, the assembly part 114 includes a stud 1143, and the filter plate 13 is connected to the stud 1143 by fasteners.

[0038] With the assembly of the snap-fit ​​arm 1141, the limiting stop plate 1142, and the stud 1143, a gap 15 is formed between the outer side wall of the filter plate 13 and the air guide shroud 111. That is, under the action of the assembly part 114, the filter plate 13 and the outer side wall of the air guide shroud 111 are not in contact at all, so that when the airflow passes through the filter plate 13, airflow flows over both sides of the filter plate 13, thereby further improving the heat dissipation performance of the filter plate 13.

[0039] Based on this, a vent 115 is provided on the outer wall of the air guide shroud 111 at the position corresponding to the filter plate 13. One end of the vent 115 is connected to the inner cavity of the air guide shroud 111, and the other end is connected to the gap 15. Thus, when the cooling fan 1 is running, air can also enter through the vent 115. On the one hand, this further increases the air intake capacity of the cooling fan 1, and on the other hand, it promotes the airflow to flow into the gap 15 and the vent 115 in sequence, which helps to increase the airflow through the filter plate 13 and further improve the heat dissipation and cooling capacity of the filter plate 13.

[0040] For any cooking device, such as a microwave oven or a steam oven, the relevant technical content provided in this embodiment can be included. Accordingly, the cooking device is equipped with the cooling fan 1 on its electrical side 2 to dissipate heat and cool conventional electrical components of the cooking device, such as the magnetron 3, microwave inverter board assembly 4, and control panel assembly 5, located on the electrical side 2; the rear plate 6 of the cooking device is provided with an air inlet corresponding to the cooling fan 1, so that air can be drawn in from the air inlet of the rear plate 6 when the cooling fan 1 is running. Since this is basically the same as the setting position of conventional fans in existing cooking devices, it will not be described in detail.

[0041] In addition, the cooking device also has a cooking cavity, as well as conventional components such as a door and a shell. Since these conventional components can be directly referred to in the prior art, they will not be described in detail here.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
