Example one

This embodiment provides a kitchen appliance, this kitchen appliance can be lampblack absorber 1000, integrated kitchen etc, this embodiment uses lampblack absorber 1000 to explain as the example, as shown in fig. 1, the lampblack absorber 1000 of this embodiment includes lampblack absorber main part 200 and dustcoat 300, air intake 3201 has been seted up on the dustcoat 300, under the effect of lampblack absorber main part 200, the waste matter of furnace end 2000 burning and the harmful oil smoke to the human body that produces in the culinary art process loop through air intake 3201, dustcoat 300 and lampblack absorber main part 200 and then discharge to the open air. In addition, lampblack absorber 1000 still includes temperature sensing module 100 and microprocessor, temperature sensing module 100 sets up in dustcoat 300 and is connected with the microprocessor communication, furnace end 2000 heats up the production of heat when using, temperature sensing module 100 detects the energy of furnace end 2000 radiation, temperature sensing module 100 sends signal amplification circuit and analog-to-digital conversion circuit after turning into the signal of telecommunication with the temperature signal that detects, later, it sends control signal to other control module to transmit microprocessor to transmit the signal according to the signal of receiving. For example, when the temperature of the furnace end 2000 is high, the temperature sensed by the temperature sensing module 100 is high, and at this time, an electrical signal, such as a high level signal, may be generated, and after the microprocessor senses the high level signal, the microprocessor sends a corresponding control signal to another control module, and the microprocessor may also send a control signal to another control module according to the change of the electrical signal. The microprocessor can also receive data signals sent by other sensors, and the actual temperature of the furnace end 2000 is calculated by combining the data signals of other sensors, so that the temperature measurement accuracy is improved. For the type of the temperature sensing module 100, the embodiment is not limited, and for example, the temperature sensing module may be configured as an active infrared temperature sensor or a passive infrared temperature sensor. The active infrared temperature measurement sensor can emit infrared rays, the infrared rays are reflected after contacting the object to be measured and are received by the active infrared temperature measurement sensor again, and the temperature of the object to be measured is measured; the temperature measurement principle of the passive infrared temperature measurement sensor is as follows: when the temperature of the object is higher than zero thermodynamic temperature, infrared rays radiate to the periphery, and the passive infrared temperature measuring sensor detects the infrared radiation energy of the object to realize the detection of the temperature of the object to be detected. Besides the two types, any infrared temperature measuring sensor capable of realizing non-contact measurement of the temperature of the object to be measured is within the protection scope of the technical scheme of the invention.

As shown in fig. 1 and 2, the housing 300 of the present embodiment includes a housing main body 320 and a decorative panel 310, and the decorative panel 310 is disposed at an outer side of the housing main body 320 to realize an aesthetic appearance of the whole shape of the range hood 1000. Preferably, the decorative panel 310 and the cover main body 320 are detachably connected, so that the decorative panel 310 and the cover main body 320 can be quickly detached, and a good cleaning effect on the decorative panel 310 can be conveniently achieved.

The existing temperature sensing module comprises a probe mechanism and an outer connecting line, wherein the probe mechanism is in communication connection with a control mechanism of the range hood through the outer connecting line, the probe mechanism can detect the temperature of a cooking bench and feed the temperature back to the control mechanism of the range hood, and the control mechanism adjusts the on-off or working mode of the range hood according to the received temperature of the cooking bench. Because the communication connection distance between the control mechanism and the probe mechanism is too far, the interference of the external environment obviously influences the accuracy of the temperature data detected by the probe mechanism and received by the control mechanism, and thus the accurate adjustment of the working state of the range hood cannot be realized. Specifically, the existing control mechanism is used for analyzing temperature data detected by the temperature sensing module, the external connection line is long, the temperature data detected by the temperature sensing module acquired by the control mechanism has hysteresis, and the real-time performance and accuracy of the temperature data detected by the temperature sensing module acquired by the control mechanism are poor. In addition, the external connection wire is long, and the temperature data can be distorted in the external connection wire transmission process, for example, the temperature actually detected by the temperature sensing module is 20 ℃, the temperature detected by the control mechanism can be distorted to be 25 ℃, 30 ℃ and the like through the transmission of the long external connection wire.

In order to solve the above problem, as shown in fig. 2 to 4, the temperature sensing module 100 of this embodiment includes a housing 30, a probe mechanism 10 and a first circuit board 80, the probe mechanism 10 and the first circuit board 80 are both disposed in the housing 30, the probe mechanism 10 is in communication connection with the first circuit board 80, and the first circuit board 80 is in communication connection with a control mechanism of the range hood. Because probe mechanism 10 and first circuit board 80 all set up in casing 30, so the communication connection distance between probe mechanism 10 and the first circuit board 80 is shorter, the real-time nature that first circuit board 80 can receive the temperature data that probe mechanism 10 detected fast is strong, in addition, because the communication connection route is short, the distortion problem can not take place for temperature data, so first circuit board 80 can receive the accurate temperature data that probe mechanism 10 detected fast, first circuit board 80 can send accurate control command to the control mechanism of lampblack absorber through accurate and real-time strong temperature data, thereby realize the accurate adjustment to lampblack absorber operating condition. Because the control instruction sent by the control mechanism of the range hood by the first circuit board 80 is carried out in a simple binary form, the influence of a longer communication connection path on the control instruction is smaller, and the accurate control on the range hood cannot be influenced. As shown in fig. 2, there are at least two probe mechanisms 10, each probe mechanism 10 can correspond to a corresponding furnace end 2000 and can only detect the temperature of the corresponding furnace end 2000, so as to avoid the problem that the temperature of a single furnace end 2000 is not accurately detected due to mutual influence between different furnace ends 2000. The probe mechanism 10 in this embodiment is set to be two to correspond to the range hoods of two burner 2000, of course, in other embodiments, the probe mechanism 10 may also be set to be one, three, four or more, so that the temperature sensing module 100 can be adaptively selected according to the specific number of the burner 2000.

As shown in fig. 2 and 12, the housing 30 is provided with a light-transmitting opening 36, and the light-transmitting opening 36 can allow the light path emitted from or received by the probe mechanism 10 to pass through. In addition, with reference to fig. 2 and fig. 12, the temperature sensing module 100 of this embodiment further includes a filter component 60, the filter component 60 is disposed at the light-transmitting opening 36, the filter component 60 filters the received radiation energy, and after stray interference light is filtered out, the infrared radiation energy is transmitted to the probe 11, the probe 11 is connected to the microprocessor, and the microprocessor performs corresponding processing according to signal changes in the probe 11, so that the temperature sensing module 100 can realize accurate detection of temperature.

In the prior art, the temperature sensing module 100 is provided with two probe mechanisms 10, and each probe mechanism 10 corresponds to one filter assembly 60, which results in high cost of the temperature sensing module 100. In order to solve the above problem, as shown in fig. 2 and 12, the temperature sensing module 100 in this embodiment further includes a support 20, at least two probe mechanisms 10 are disposed on the support 20, and light paths emitted from or received by the at least two probe mechanisms 10 can pass through the optical filter assembly 60. The at least two probe mechanisms 10 of this embodiment can share one filter assembly 60, and realize that the single light-transmitting opening 36 detects the function of at least two burner 20000, the structure of this temperature sensing module 100 is simple and the cost is low.

Further, as shown in fig. 12, the number of the probe mechanisms 10 in this embodiment is two, the central lines of the light paths emitted from or received by the two probe mechanisms 10 form an included angle, and the intersection position of the central lines of the two light paths is located at one side of the probe mechanism 10 close to the filter assembly 60, so that the temperature detection in a large range can be realized.

As shown in fig. 2, the temperature sensing module 100 of this embodiment still includes wire assembly 70, and probe mechanism 10 passes through wire assembly 70 communication connection with first circuit board 80, compare in the network, bluetooth or infrared communication connected mode, and wire assembly 70's transmission mode can guarantee that the transmission of temperature data is more stable and more accurate, and wire assembly 70's data transmission ability receives the vibration that the lampblack absorber work produced littleer, can realize the accurate detection of temperature sensing module 100 in the great environment of vibration. Specifically, the length of the wire assembly 70 of the present embodiment is 10mm to 50mm, and the wire assembly 70 is short, so that the problem of delay or distortion of temperature data during transmission can be avoided. As shown in fig. 2, the lead assembly 70 includes a power line 71, a ground line 72 and a communication link 73 for signal transmission, and the power line 71 is provided to achieve better power supply to the probe mechanism 10. The setting of ground wire 72 can avoid temperature sensing module 100 to take place the short circuit problem, avoids temperature sensing module 100 to damage at the in-process that uses, further can also avoid temperature sensing module 100 because the conflagration that the short circuit caused, can guarantee the personal safety of user when using the lampblack absorber.
