Description

Technical Field

[0001] The utility model belongs to the technical field of cooking appliances, and particularly relates to a double-air-channel cooling cooking appliance. Background Art

[0002] Modern cooking appliances such as air fryers and pizza machines are favored by people for their convenience and ability to make delicious food. They not only save cooking time but also improve the quality of life. However, these devices must be cooled and exhausted in a timely manner during use to avoid excessive internal cavity temperature caused by poor air circulation, which will not only reduce cooking efficiency and food quality but also may shorten the service life of the device. Currently, many air fryers and pizza machines are only equipped with a single rear exhaust port, which often results in insufficient exhaust efficiency. To improve this situation, some devices strengthen air flow by increasing the fan speed. Although this can relieve air stagnation to a certain extent, it also brings new problems: excessive wind force may not meet the requirements of the wall temperature rise test in safety specifications, making users feel uncomfortable, increasing the risk of scalding, and may cause unnecessary power consumption. Content of the Utility Model

[0003] The utility model provides a double-air-channel cooling cooking appliance, aiming to solve the problem that the hot air in the cooking cavity of the existing cooking appliances cannot be quickly discharged.

[0004] To solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0005] A double-air-channel cooling cooking appliance includes a cooking cavity, a heat dissipation cavity is arranged outside the cooking cavity, the heat dissipation cavity is communicated with the cooking cavity, at least two heat dissipation air channels and a heat dissipation component for discharging the hot air in the cooking cavity are arranged in the heat dissipation cavity, and each heat dissipation air channel is provided with an air outlet.

[0006] Preferably, the heat dissipation component includes a heat dissipation fan, and the heat dissipation fan is located in the heat dissipation cavity.

[0007] Based on the above solution, directly placing the heat dissipation fan in the heat dissipation cavity can enable the fan to directly act on the heat in the cooking cavity and quickly and centrally discharge it, thus effectively avoiding local overheating. By precisely controlling the temperature in the cooking cavity, the fan not only helps to maintain temperature uniformity but also ensures that the food is heated uniformly during cooking, thereby guaranteeing the quality and taste of food cooking.

[0008] Preferably, it further includes a hot air cavity, the hot air cavity is located between the heat dissipation cavity and the cooking cavity and is communicated with the heat dissipation cavity, and the heat dissipation cavity is communicated with the outside atmosphere through the air outlet.

[0009] Based on the above solution, the hot air cavity is located between the heat dissipation cavity and the cooking cavity and is connected to the heat dissipation cavity, forming an orderly hot air flow path to ensure that the hot air generated in the cooking cavity can be guided to the hot air cavity and then effectively discharged through the heat dissipation cavity, avoiding the accumulation of excessive heat in the cooking cavity.

[0010] Preferably, there are two heat dissipation air ducts, and the heat dissipation fan is located between the two heat dissipation air ducts.

[0011] Preferably, two air outlets are provided on the outer side wall of the heat dissipation cavity, and the two heat dissipation air ducts are respectively connected to the two air outlets.

[0012] Based on the above solution, this layout can balance the wind force in the air ducts, ensure that the hot air is distributed from the cooking cavity to the two air ducts, improve the heat dissipation efficiency, and the position of the fan is conducive to more efficiently guiding the hot air from the cooking cavity to the heat dissipation air ducts, accelerating the flow speed of the hot air, thereby quickly reducing the temperature of the cooking cavity; in addition, the design of the two air outlets helps to disperse the discharged hot air and reduce the local overheating that may be caused by a single air outlet.

[0013] Preferably, it further includes a hot air fan. The hot air fan is located in the hot air cavity, and a motor is provided in the heat dissipation cavity. Both the hot air fan and the heat dissipation fan are installed on the output shaft of the motor.

[0014] Based on the above solution, the coordinated operation of the hot air fan and the heat dissipation fan can more effectively control the temperature and hot air flow in the cooking cavity and improve the cooking efficiency.

[0015] Preferably, a partition is provided between the hot air cavity and the cooking cavity. A number of air outlet channels for communicating the cooking cavity with the heat dissipation cavity are provided between the partition and the outer wall of the cooking cavity.

[0016] Based on the above solution, the partition serves as a heat buffer zone to reduce the drastic fluctuation of the internal temperature of the cooking cavity. The hot air can be orderly guided from the cooking cavity to the heat dissipation cavity through the air outlet channels, optimizing the hot air flow path and maintaining the stability of the cooking temperature. In addition, the partition provides physical separation, which helps to reduce the pollution or grease accumulation that may be caused to the heat dissipation cavity during the cooking process.

[0017] Preferably, a filter screen for filtering impurities is provided in the middle area of the partition.

[0018] Based on the above solution, the filter screen can capture the grease, food residues and other fine particles generated during the cooking process, thereby purifying the hot air.

[0019] Preferably, the heat dissipation cavity is covered with a housing, and a number of air outlet meshes are provided on the housing, and the air outlet meshes cover the air outlets.

[0020] Based on the above solution, the air outlet net can serve as a filter layer to block the grease and food debris that may be generated during cooking and prevent them from being discharged into the external environment along with the hot air.

[0021] Preferably, the cooking appliance is an air fryer or a pizza maker.

[0022] The beneficial effects of the present utility model are as follows:

[0023] The present utility model provides a double-duct cooling cooking appliance. By arranging at least two heat dissipation ducts and corresponding heat dissipation components in the heat dissipation cavity, not only the air outlet area is increased, but also through reasonable wind force distribution, the temperature inside the cooking appliance is effectively reduced. And by arranging at least two heat dissipation ducts, the problem of excessive wind force at a single air outlet caused by increasing the fan speed to strengthen air flow is solved, so that the wind force can meet the test requirements for wall surface temperature rise in safety specifications, reduce noise pollution, and improve the user's comfort. The multiple heat dissipation ducts disperse the wind force reasonably, which not only meets the safety specifications but also reduces the noise, providing a quieter and more comfortable cooking environment for the user. In addition, the dispersion of the wind force also reduces the risk that the user directly contacts the high-temperature hot air during use, reduces the possibility of scalding, and improves the safety of use. At the same time, the increase in energy consumption caused by increasing the fan speed is avoided, achieving the goal of energy conservation and environmental protection.
