Description

  The present invention relates to the field of cooking appliance parts, and more particularly to a rotating shaft fixing structure of a cooking appliance and a cooking appliance to which the structure is applied.

  As the quality of life improves, people's needs for cooking are gradually increasing. The equipment used for cooking is also developing more and more, and cooking equipment is, of course, one of the most frequently used cooking equipment. A cooking device on the market generally has an upper heating source, an oven pan and a base, and a motor and a rotating shaft are disposed in the base, and the oven pan is disposed on the base and connected to the motor rotating shaft. Then, by driving the rotation of the oven pan through the motor, the food placed on the oven pan is uniformly heated by the action of the upper heating source, so that delicious food can be cooked.

  In general, the rotating shaft of the oven pan in the cooking device according to the conventional technique is configured by a method of assembling parts. For example, Patent Document 1 below discloses a rotating shaft fixing structure of a cooking device, as shown in FIG. 1, having an oven pan and a base 1A, and a motor 301 fixed under the base 1A. The connector 5 ′ is fixed to the rotating shaft of the motor 301, and a hole 1A3 is set in the base 1A so that the connector can pass. The connector 5 ′ passes through the hole and is connected to the oven pan, and then the motor 5 The connector 5 'and the oven pan are rotated by driving 301, and a triangular plate for fixing the upper end of the connector is disposed on the connector. In the rotary shaft fixing structure, after the connector is arranged on the motor, the motor is arranged on the base so that the connector passes through the hole on the base, and the triangular plate for fixing the connector is arranged on the base. As is clear from this, such an assembly relationship causes a relatively large assembly error in the assembly process of the cooking device, and it is difficult to guarantee the concentricity between the components of each rotating shaft. Reduce the yield rate of equipment. When the rotating shaft of the oven pan rotates, the concentricity between the components of each rotating shaft is not high, so the wear of each component of the rotating shaft is promoted, the frictional force between each rotating shaft is increased, and the power consumption The consumption is increased and the electrical consumption of the cooking equipment is increased. Since the concentricity is low, there is a risk of causing noise during rotation, and the rotation of the oven pan is unstable, which affects the normal use of the user.

China Utility Model No. ZL201620111590.2

  The objective of this invention is providing the rotating shaft fixed structure of a cooking appliance, and the cooking appliance to which it is applied. According to the fixing structure, the rotating shaft and motor of the cooking device can be stably fixed, the concentricity between the components of the rotating shaft can be ensured, and the rotation efficiency can be increased, and the oven pan is stable. The user can use the cooking device with peace of mind.

  In order to achieve the above object, the present invention provides the following technical solution.

  The rotating shaft fixing structure of the cooking device according to the present invention has a base and an oven pan, a motor is disposed in the base, a drive shaft is connected to the motor, In a rotating shaft fixing structure of a cooking appliance, in which a rotating shaft is disposed and is fitted and connected to the base via the rotating shaft, the base further includes a mounting base for fixing a motor and a driving shaft, and the mounting base Has a connector for connecting the upper and lower sides and a lower lid, and the connector and the lower lid are connected to form an internal motor chamber and a rotating shaft chamber, and the motor is disposed in the motor chamber. The drive arm extends to the rotary shaft chamber, and the drive shaft is disposed in the rotary shaft chamber and is connected to the motor drive arm. Is disposed an upper opening so that the rotation shaft of Npan is fitted, the oven pan is connected to a drive shaft through the upper opening through the rotary shaft is rotated by driving the motor.

  The rotating shaft fixing structure of the cooking device according to the present invention is compared with the rotating shaft fixing structure of the cooking device according to the conventional technique. The conventional rotating shaft fixing structure for cooking equipment has the problem that the components of each rotating shaft are assembled to the base, the assembly relationship is complicated, and the assembly standards are not uniform. Concentricity between parts cannot be guaranteed. In order to solve this problem, the present inventor has intensively studied and came to improve the concentricity problem of the rotating shaft fixing structure. Further, since an independent mounting base is added, the components of the rotating shaft are unified and fixed in the mounting base, and the mounting base is disposed on the base. The motor and the drive shaft are set integrally with the mounting base as the mounting reference, and are integrally formed in the mounting base to reduce the influence of assembly errors on the concentricity due to assembly. be able to. Furthermore, since the mounting base is disposed on the entire base, the rotary shaft of the oven pan is fitted into the upper opening of the mounting base and connected to the drive shaft, and the components of each rotary shaft of the entire rotary shaft fixing structure The oven pan is rotated more smoothly so that the concentricity between them is unified. In addition, since the concentricity between the rotating shafts is unified, the efficiency of overturning of the rotating shafts becomes high, and the frictional force generated due to the low concentricity between the rotating shafts is effectively weakened so that the cooking equipment This reduces power consumption and leads to energy saving. On the other hand, it increases the concentricity between the rotating shafts of cooking equipment, reducing the frictional force between the components of each rotating shaft, and the problem of failure due to frictional force, for example, large frictional force can cause heat generation of the rotating shaft The problem is that the motor may be damaged if it is extremely high and severe, or the rotating shaft may collide with the rotating shaft, which may cause noise and affect the user's use experience. Some problems can be solved. Thereby, the user can use cooking equipment safely and can enjoy cooking food.
