Description

Cooker with improved heat dissipation structure of support arm

technical field

The invention belongs to the technical field of cooking equipment, in particular to a cooker with an improved heat dissipation structure of a support arm.

Background technique

As people continue to innovate cooking methods and continuously improve food quality requirements, open cookers gradually appear on the market. The cooker is generally composed of a burner, a baking pan and a base. The roasting pan is detachably installed on the base, and the burner is set above the baking pan. The food on the baking pan is heated and roasted to achieve the purpose of cooking. When in use, because the cooker has the advantages of being able to place or take out food at any time, put seasonings on the food in the baking pan at any time, and flip the food at any time, and has the advantages of energy saving, environmental protection, uniform heating, and easy operation, it is more and more popular among people. .

In the prior art cooker, since the burner is provided with a heating device, there is a certain amount of heat, so generally a heat dissipation fan or a cooling hole is arranged in the burner to dissipate heat from the heating device. In practical application, since the cooker irradiates heat toward the base through the heating device of the burner, the food on the grill pan set on the base can be heated and cooked. However, in the process of light wave irradiation, the support arm and the base are unavoidably in the light wave irradiation range, and are also heated. As for the base, the inner space of the base is large, and a heat dissipation fan or a corresponding heat dissipation structure can be arranged accordingly for heat dissipation and cooling. However, for the support arm, the support arm is located on one side of the base and mainly plays a role in supporting the burner head. The inner space of the support arm is relatively small, so it is difficult to install a heat dissipation fan or a corresponding heat dissipation structure. If the support arm is overheated, the hardness will be reduced, the deformation will be damaged, and it will not be able to support the burner. The current heat dissipation solution for the support arm is to expand the position of the support arm outward to avoid the range of light waves. However, such a design will increase the volume of the whole machine, increase production and transportation costs, and cannot fundamentally solve the heat dissipation problem of the support arm.

Contents of the invention

The object of the present invention is to provide a cooker with an improved heat dissipation structure of the support arm. Aiming at the heat dissipation problem of the support arm, a heat dissipation structure formed by combining the support arm and the base is provided, which can effectively support the heat dissipation of the whole machine in the light wave irradiation range during the operation process. The heat of the arm and the base is discharged or diffused at the same time, so that the temperature of the support arm is maintained at a normal state, and the hardness of the support arm is reduced due to overheating, deformation and damage, which affects the support effect, prolongs the service life of the cooker, and reduces the volume of the cooker. Reduce production and transportation costs.

Provide in order to achieve the above object, technical scheme of the present invention:

Compared with the prior art, a cooker with an improved heat dissipation structure of the support arm of the present invention, especially for a cooker with a frame structure composed of a burner head, a support arm and a base, the burner head is mainly supported by a support arm. It is above the base, so the range of light waves emitted from the furnace will cover the support arm. When the support arm is overheated, its hardness will decrease, and it will be damaged due to deformation. On the other hand, due to the space of the support arm Limited, can not set the corresponding heat dissipation structure. In the prior art, there is a design of providing heat dissipation holes on the support arm, but the heat dissipation effect is limited, and the heat dissipation problem of the support arm cannot be fundamentally solved. For this reason, in order to solve the heat dissipation problem of the support arm, the inventor has obtained through many experiments and studies that by using the inner space of the base of the cooker, a heat dissipation air duct connecting the base and the support arm is provided, and a first The fan blows air toward the support arm through the heat dissipation air duct, and discharges the heat of the support arm from the first air vent to realize heat dissipation of the support arm.

Furthermore, the heat dissipation air duct is extended to the burner part, so that the base of the cooker, the support arm and the burner form a ring-shaped heat dissipation system, which effectively diffuses the heat of the support arm quickly and discharges it to the outside, improving the heat dissipation efficiency.

Still further, the second vent is provided on the back of the connection part of the furnace head and/or the lower surface of the connection part. Since the user operates the cooker generally at the front of the burner, that is, the front end of the heating part, the second vent is arranged on the back or lower surface of the burner connection part, so that the heat discharged from the support arm is discharged at the back of the cooker , to avoid spraying in the direction of the user, causing burns, and ensuring the safety of the user.

On the basis of the above, the base further includes a third vent communicating with the heat dissipation air duct, and the third vent is provided on the upper surface of the base and/or the bottom of the base. By adding a vent connected to the heat dissipation air duct at the base, while the support arm dissipates heat, the heat of the base is also quickly discharged to the outside, and at the same time, the base is dissipated to further improve compatibility.

To further expand the compatibility of the heat dissipation air duct for improvement, the base is also provided with a control circuit board, and the control circuit board is arranged in the heat dissipation air duct, so as to dissipate heat for the support arm and also integrate the control circuit board in the whole machine The heat generated during operation is discharged together. Especially for cookers that use thyristor elements to control the heating device on the stove, the temperature of the control circuit board equipped with thyristor elements is particularly high, and a corresponding heat dissipation structure needs to be provided. Therefore, the present invention arranges the control circuit board for heat dissipation. In the air duct, the heat dissipation structure of the support arm is effectively used to simultaneously dissipate heat through the heat dissipation air duct.

The setting of the fan is further improved. The first fan is a centrifugal fan connected to the outside, which is located at the beginning of the cooling air duct, draws the external cold air into the cooling air duct, and blows heat toward the support arm to dissipate heat. The centrifugal fan is provided with two air outlets, one end is a radial air inlet, and the other end is an axial air outlet, and a motor-driven impeller is arranged inside the fan. When working, the airflow enters from the radial air inlet, changes the wind direction with the rotation of the impeller, and then blows out from the axial air outlet; during the rotation of the impeller, the wind force increases with the inertial rotation of the centrifugal force of the impeller. Therefore, the first fan is a centrifugal fan connected to the outside, which draws cold air into the heat dissipation duct, then rotates the fan impeller to increase the wind force, and then blows air to the support arm to cool the heat of the support arm, so as to further improve the heat dissipation effect.

Further, the side wall of the base is provided with a fourth vent, and the fourth vent is located at the connection between the support arm and the base; the first fan is a centrifugal fan sleeved on the fourth vent, and the The external cold air is sucked into the heat dissipation air channel through the fourth air vent, and blows heat to the support arm to dissipate heat. Set the fourth vent on the side wall of the base at the connection between the support arm and the base, connect the centrifugal first fan to the fourth vent, and draw the external cold air into the cooling air duct from the fourth vent to further shorten the fan Output the distance of the heat dissipation air flow, and blow heat to the support arm to improve the heat dissipation efficiency.

Still further, the connection part of the burner head further includes a second fan, which is a suction fan, which draws the heat of the support arm to the connection part and discharges it to the outside through the second vent. The heat in the support arm is discharged to the direction of the burner, so that the heat of the support arm is quickly discharged from the second vent to the outside, and the heat of the support arm is further diffused to enhance the heat dissipation effect.
