Background

Gas cookers/liquified gas cookers are commonly used as cookers in modern homes for heating or cooking food. However, in some cases, the user may forget to turn off the cooker during cooking, and the food in the pot is heated for a long time, so that the liquid is dried up, and the phenomenon of dry burning occurs. If a plurality of cooking is continuously carried out, the food can be burnt to cause waste, and the temperature of the cooker can be overhigh in serious conditions to cause fire disasters. Therefore, in the field of cooking utensils, how to intelligently turn off a gas switch so as to prevent dry burning is an important research topic.

The anti-dry heating device integrates an anti-dry heating function into a cigarette machine, and determines the temperature state of the surface of an object to be measured through a non-contact temperature measuring module. The non-contact temperature measurement module adopts an infrared thermopile sensor. The infrared thermopile sensors are in one-to-one correspondence with the cookware, and the central lines of the infrared thermopile sensors and the cookware are on the same straight line, namely the center of the infrared thermopile sensor is positioned right above the center of the cookware. In addition, the area of the temperature detection area of the non-contact temperature measurement module is not larger than the area of the bottom surface of the cookware, namely, when no object to be heated exists in the cookware, the temperature detection area can only be the range of the bottom surface of the cookware; when the objects to be heated are arranged in the cooker, the temperature detection area is at least partially covered on the upper surface of the objects to be heated in the cooker and the bottom surface of the cooker, which is not covered by the objects to be heated, of the cooker. Therefore, the non-contact temperature measuring module can be prevented from detecting the range outside the stove.

Fig. 1 shows a schematic block diagram of a range hood 100 according to an embodiment of the present invention. It should be noted that the range hood 100 shown in fig. 1 is only an example and not a limitation of the present invention, and the present invention is not limited to the embodiment shown in fig. 1. For example, fig. 1 shows that the heat releasing module 110 is connected with the range hood control device 130, and the range hood control device 130 is connected with the range hood communication module 120, but alternatively, the heat releasing module 110 may be directly connected with the range hood communication module 120. For another example, fig. 1 shows that the range hood control device 130 is a control chip including a first chip 132 and a second chip 134 (to be described later), but the range hood control device 130 may be a single chip or include a greater number of chips (e.g., three, etc.). Alternatively, the range hood control device 130 may also be other types of devices, such as a Programmable Logic Controller (PLC) or the like. For another example, the range hood 100 may not divide the switch control board 140 and the power supply board 150, but implement all the components on the same circuit board. Also for example, both the light emitting diode display (fig. 1, abbreviated as LED display) and the keys may be optional, i.e., range hood 100 may optionally include these components.

As shown in fig. 1, the range hood 100 includes a heat releasing module 110 and a range hood communication module 120. The heat release module 110 is used for detecting the temperatures of at least two burners on the stove to obtain temperature data of the at least two burners. The range hood communication module 120 is configured to send the temperature data or a dry-burning instruction generated when the temperature data reaches a dry-burning condition to the kitchen range, where the dry-burning condition is that the temperature data of any one of the at least two furnace ends exceeds the temperature threshold and/or the change rate of the temperature data of any one of the at least two furnace ends exceeds the change rate threshold.

For example, the heat release module 110 may be disposed at any suitable position as long as it can detect the temperatures of at least two burners. For example, the heat release module 110 may be located on a central vertical line of the two burners farthest from among the at least two burners. The two burners farthest away may be considered as the outermost two burners on the stove, for example, the leftmost burner and the rightmost burner on the stove. The heat releasing module 110 is disposed on the perpendicular bisector of the two burners farthest away, which is beneficial to detecting the temperatures of the at least two burners in a relatively balanced manner.

It is noted that the temperature of any burner refers to the temperature at a specific location within a predetermined distance (e.g., 10 cm) around the burner, which may be preset at the time of production or installation of the range hood 100, known to the range hood control device 130 or the cooktop communication device 410 described below. The temperature at the particular location may be determined by the range hood control 130 or the cooktop communication device 410 described below based on the temperature data collected by the heat release module 110. It will be appreciated that in the case of a pan above the burner, the temperature of any burner is the temperature in the pan above it.

Illustratively, the pyroelectric module 110 may be implemented using a single pyroelectric infrared sensor, such as an OTPA-16PM4S sensor. The pyroelectric infrared sensor can comprise a sensing detection element, an interference filter and a field-effect tube matcher. The pyroelectric infrared sensor has the following advantages: the self-body does not emit any type of radiation, and the device has small power consumption, good concealment and low price.

The pyroelectric module 110 may detect the temperature within a preset distance (i.e., its temperature detection range) in real time. For example, the pyroelectric module 110 can detect 256(16 × 16) temperature points at a time, i.e., the temperatures at 256 positions. The heat release module 110 may transmit the detected temperature data to the range hood communication module 120 or the range hood control device 130. In this case, the total temperature data collected by the heat release module 110 includes temperature data of a plurality of burners of the oven, and the temperature data of each burner may be extracted from the total temperature data, and the temperature data of each burner may be subsequently operated.

The temperature detection range of the heat release module 110 covers at least two burners on the stove, and the heat release module 110 can detect the temperatures of the at least two burners at one time.

Figure 2 shows a front view of a range hood and a cooker according to an embodiment of the present invention. Figure 3 shows a left side view of a range hood and a cooker according to an embodiment of the present invention. The positional relationship of the heat release module and the burner of the cooktop can be understood with reference to fig. 2 and 3.

The hood communication module 120 may be a wired communication module or a wireless communication module, which may be set as needed.

Under the condition that the range hood communication module 120 sends the temperature data to the stove, the stove can control the electromagnetic valve corresponding to the stove head to close when the temperature data of any one of the at least two stove heads exceeds a temperature threshold value and/or the change rate of the temperature data of any one of the at least two stove heads exceeds a change rate threshold value. Under the condition that the range hood communication module 120 sends the dry combustion instruction to the range, the range can control the electromagnetic valve corresponding to the furnace end to close when receiving the dry combustion instruction, wherein the dry combustion instruction is generated by the range hood 100 when the temperature data of any one of the at least two furnace ends exceeds a temperature threshold and/or the change rate of the temperature data of any one of the at least two furnace ends exceeds a change rate threshold. The rate of change of the temperature data may be an amount of change of the temperature data per unit time.

According to the utility model discloses lampblack absorber, through the heat release module on the lampblack absorber once only detect the temperature of two at least furnace ends on the cooking utensils to with temperature data or dry combustion method instruction send cooking utensils, be convenient for in time stop heating the pan when taking place to dry combustion method. In this kind of prevent dry combustion method scheme, the heat release module has great detection range, need not to install like prior art with the pan one-to-one infrared thermopile sensor can realize the temperature detection of a plurality of furnace ends, can reduce product cost effectively like this.

According to one embodiment, the heat releasing module 110 is connected to the range hood communication module 120, and the range hood communication module 120 is configured to receive the temperature data from the heat releasing module 110 and send the temperature data to the cooker.

The range hood communication module 120 may be directly connected with the heat releasing module 110 and directly output temperature data to the cooker. Under the condition, one end of the range hood does not process the temperature data, one end of the cooker judges whether a cooker on any burner is in a dry burning state currently or not based on the temperature data of the burner, and if so, the corresponding electromagnetic valve can be closed.

According to an embodiment, the range hood 100 may further include a range hood control device 130 connected to the heat releasing module 110 and the range hood communication module 120, where the range hood control device 130 is configured to receive the temperature data from the heat releasing module 110, generate the dry-burning instruction when the temperature data reaches the dry-burning condition, and send the dry-burning instruction to the range hood communication module 120.

The smoke ventilator control device 130 may be implemented by using electronic components such as a comparator, a register, and a digital logic circuit, or by using processor chips such as a single chip microcomputer, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), and an Application Specific Integrated Circuit (ASIC), and peripheral circuits thereof.

Both the temperature threshold and the rate of change threshold may be set as desired, and may be any suitable values, which are not limited herein. For example, the temperature threshold may be 298 degrees.

For example, the range hood control device 130 may include at least two comparators in one-to-one correspondence with at least two burner, each comparator for comparing temperature data of the corresponding burner with a temperature threshold or comparing a change rate of the temperature data of the corresponding burner with a change rate threshold, and outputting a comparison result signal. For example, the comparator may output a high level when the temperature data exceeds the temperature threshold, and a low level otherwise. For example, if the stove has two burners, the smoke ventilator control device 130 may include two corresponding comparators, and the output of the two comparators can be regarded as a two-bit digital signal, 00 represents that the temperatures of the two burners do not exceed the temperature threshold, 01 represents that the temperature of the first burner exceeds the temperature threshold, 10 represents that the temperature of the second burner exceeds the temperature threshold, and 11 represents that the temperatures of the two burners both exceed the temperature threshold. The smoke control device 130 may optionally not output a command when the results of the two comparators are 00. When the results of the two comparators are 01, 10, and 11, the smoke ventilator control device 130 can optionally send the digital signals 01, 10, and 11 to the cookers as dry-burning instructions, and when the cookers receive the digital signals, the cookers consider that a dry-burning situation occurs, and can control the corresponding electromagnetic valves to be closed to stop heating the cookers. For example, when the cooker receives the digital signal 01, the cooker can control the first electromagnetic valve corresponding to the first burner to close; when the cooker receives the digital signal 10, the cooker can control a second electromagnetic valve corresponding to a second burner to be closed; when the cooker receives the digital signal 11, the two electromagnetic valves can be controlled to be closed.

The above scheme of comparing by the comparator and sending part of the digital signal output by the comparator to the cooker as the dry-burning command is merely an example and not a limitation of the present invention, and any other suitable scheme may be adopted to realize the judgment of the dry-burning situation and generate the dry-burning command with other representation forms.

For example, the alarm device may be provided at a front end of the range hood 100, which refers to an end of the range hood 100 close to a user. For example, the alarm device may be provided on a control panel of the range hood 100.

According to one embodiment, the alarm device may comprise one or more of a display, a flashlight, a speaker. Illustratively, the alert information may include one or more of audio information, video information, image information, light information, and the like.

Referring back to fig. 1, the switch control board 140 and the power board 150 are shown. The switch control panel 140 may be disposed on the front side of the range hood 100, and is mainly used for interacting with a user, for example, a user may input an instruction through a key (e.g., a working position control key) on the switch control panel 140, and may view information (e.g., a working position of a fan, etc.) related to the range hood through an LED display device on the switch control panel 140.
