Embodiment approach 1

[0050] Figure 7 It is an operation flowchart showing the control of the operating state of the range hood in Embodiment 1. This operation flowchart is also processed by the control unit 130 . Among them, on the operation panel 120 (refer to image 3 as well as Figure 5 ) when the air volume automatic switch 123 is pressed and the range hood 100 runs automatically, this action flow chart is executed. Therefore, the control unit 130 controls the air volume of the fan 116 and / or the rotation speed of the filter 118 based on the temperature detected by the compound eye temperature sensor 300 , and independently controls the subsequent automatic operation.

[0051] First, the control part 130 detects the temperature of the upper part of the cooker 200 by the compound eye temperature sensor 300 (S200). like Figure 4 As shown, the compound eye temperature sensor 300 can be divided into 64 areas to detect the temperature above the cooker 200 . For example, when cooking is per...

Embodiment approach 2

[0056] Figure 8 It is an operation flowchart showing the control of the operating state of the range hood according to the second embodiment. This operation flowchart is also processed by the control unit 130 . Wherein, this operation flowchart is also executed when the range hood 100 is automatically operated.

[0057] First, the control part 130 detects the temperature of the upper part of the cooker 200 by the compound eye temperature sensor 300 (S300).

[0058] Next, the control unit 130 judges whether or not the temperature difference of each pixel in the temperature rise range detected by the compound eye temperature sensor 300 has changed to a state within a specific predetermined range ( S310 ). When the temperature of the cooking utensil 250 is different from that of the cooking item, or when the cooking item is scattered in the cooking utensil 250 (stir-frying, etc.), the temperature distribution appears scattered during cooking. However, when the cooking tool 25...

Embodiment approach 3

[0062] Figure 9 It is an operation flowchart showing the control of the operating state of the range hood according to the third embodiment. This operation flowchart is also processed by the control unit 130 . Wherein, this operation flowchart is also executed when the range hood 100 is automatically operated.

[0063] First, the control part 130 detects the temperature of the upper part of the cooker 200 by the compound eye temperature sensor 300 (S400).

[0064] Next, the control unit 130 judges whether or not the temperature rise range detected by the compound eye temperature sensor 300 has moved by a predetermined value or more than a predetermined time ago ( S410 ). For example, when the cooker 250 is used to cook a cooking item, if the cooker 250 is moved, the temperature rise ranges of the cooker 250 and the cooker gradually deviate in the moving direction. In addition, when the cooking utensil 250 is moved from the heat source 210A, the portion where the heat source ...

Abstract

The invention provides a ventilation system. When a cooking utensil leaves a heat source, the air flow of a fan and / or the rotation speed of a filter are not increased. The ventilation system comprises a cooking state monitoring part (300) and a control part (130). The cooking state monitoring part (300) monitors the cooking state. The control part (130) controls the operation state of a kitchen ventilator (100) according to the monitoring result of the cooking state monitoring part (300). Based on the monitoring result, it is judged that a cooking utensil (250) has been removed from a heat source (210), the control part (130) does not increase the air flow of the fan of the kitchen ventilator (100) and / or the rotation speed of a filter.

Description

technical field [0001] The present invention relates to ventilation systems. Background technique [0002] In the past, there is a range hood that detects the temperature above the cooker by a temperature sensor installed in the range hood, and determines the air volume of the fan and / or the rotation speed of the filter according to the detected temperature to automatically operate the range hood (patent document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2018-105568 [0004] For existing range hoods like Patent Document 1, if the temperature on the top of the cooker is low, the range hood will be operated with a small air volume of the fan and / or a small filter speed. If the temperature above is high, run the range hood with a high fan volume and / or a high filter speed. In cooking using cooking utensils such as a frying pan and a pot, in order to serve dishes after cooking, the cooking utensils may be held close to a plate to serve dishes. [0005] In...
