AI Technical Summary
Smoke sensors are prone to fail due to accumulation of oil pollution after long-term use, resulting in insensitive detection or complete failure.
An integrated stove with a collection tube is designed. The entrance of the collection tube is upward, and the smoke passes downward from the inlet and then upward turn at least once. An oil leakage port is set at the outlet, and the smoke sensor is placed at the high position of the collection tube to avoid the ingress of the condensed oil and condensate water.
It effectively avoids the ingress of condensed oil and condensate water into the smoke sensor, extends its service life, and ensures that the smoke sensor can accurately detect the smoke volume, so that the fan air volume is not required frequently.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of integrated stoves, in particular to an integrated stove with a smoke sensor. Background Art
[0002] Range hoods have been in China for nearly 20 years, from the initial ceiling-type range hoods to side-type range hoods. The advantage of side-type range hoods is that they are closer to the stove panel and can absorb oil fumes better. The oil fumes condense into oil in the side of the smoking cavity, and fall into the oil cup at the bottom of the smoking cavity along the inner wall due to its own gravity.
[0003] Side suction range hoods can also be replaced by integrated stoves. The difference is that integrated stoves use down-discharge fans to remove oil smoke. A smoke sensor can be set in the integrated stove. The smoke sensor will feed back the size of the smoke received to the control center, and then adjust the fan air volume according to the value of the smoke volume. Users do not need to adjust the fan air volume frequently during use.
[0004] However, smoke sensors or detection heads are generally installed in places where smoke may pass. As time goes by, oil stains are likely to form in front of the probe, resulting in insensitive detection or even failure.
[0005] Therefore, the inventor conducted further research on this and developed an integrated stove with a smoke sensor, which resulted in the present invention. Utility Model Content
[0006] The utility model aims to provide an integrated stove with a smoke sensor, which can reduce the influence of oil stains on the smoke sensor.
[0007] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0008] An integrated stove with a smoke sensor, comprising
[0009] The smoke hood is provided with a collecting pipe, the inlet of the collecting pipe is upward and opposite to the oil smoke inhalation direction, the smoke first goes downward from the inlet to the outlet of the collecting pipe, then makes at least one upward turn, and then is discharged from the outlet of the collecting pipe, and a downward oil leakage port is opened in the collecting pipe at the turn;
[0010] The collecting pipe is also provided with a smoke sensor, which is located behind the oil leakage port relative to the inlet in the collecting pipe and is located higher than the oil leakage port.
[0011] Directly opposite to the direction of oil smoke inhalation, a large amount of condensed oil and condensed water will be produced at the same time. In order to extend the service life of the smoke sensor, it is necessary to prevent condensed water and condensed oil from entering the interior. The purpose of the above-mentioned design is to allow oil smoke to enter the smoke sensor smoothly, while condensed oil and condensed water will not enter the interior of the smoke sensor.
[0012] Further, the collecting pipe is fixed between the smoke hood and the wind box.
[0013] Furthermore, a transmitter and a receiver are arranged inside the smoke sensor.
[0014] Infrared smoke alarms usually contain a transmitter and a receiver. The transmitter periodically emits infrared signals, while the receiver receives and monitors these infrared signals. When smoke or flames are generated, they will scatter or absorb infrared signals. If the signal strength received by the receiver is lower than or higher than the set threshold, the alarm will be triggered.
[0015] Furthermore, a fan is arranged in the bellows.
[0016] The integrated stove uses a bellows to generate negative pressure to remove oil smoke. The bellows is set below the collection pipe to help guide the oil smoke into the collection pipe.
[0017] Furthermore, the structure of the collecting pipe is that it first goes vertically downward from the inlet, then tilts upward, and finally is distributed horizontally and then turns vertically downward.
[0018] Furthermore, there is a collecting pipe before the smoke sensor and a bellows pipe after the smoke sensor.
[0019] The smoke sensor can be used as a dividing point to carry out segmented design in order to better process components.
[0020] After adopting the above scheme, the utility model has the following advantages compared with the prior art:
[0021] The purpose of this design is to allow oil smoke to enter the smoke sensor smoothly, while condensed oil and condensed water will not enter the interior, greatly extending the service life of the smoke sensor. The core point of the design is that the smoke collection pipe has an upward collection port and an oil leakage port at the bottom, and the entire smoke sensor assembly is set in the middle of the left and right sides of the bellows. The smoke sensor will feed back the size of the received smoke to the control center, and then adjust the fan air volume according to the value of the smoke volume. Users do not need to frequently adjust the fan air volume during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0028] like Figure 1 As shown, an integrated stove with a smoke sensor includes a smoke hood 1 and a bellows. The smoke hood 1 is located above the bellows 2. The fan 21 of the bellows 2 generates negative pressure to suck the smoke from the inlet of the smoke hood 1.
[0029] A smoke sensor 3 is arranged above the bellows in the smoking hood 1, one end of the smoke sensor 3 is connected to a collecting pipe 4, and the other end is connected to a bellows pipe 5; wherein the collecting pipe 4 is first vertically downward from the entrance and then tilted upward to be connected to the smoke sensor 3, and a downward oil leakage port 41 is opened at the lowest point of the collecting pipe 4; the bellows pipe extends horizontally from the smoke sensor 3 and then turns vertically downward to be connected to the bellows, and the bellows 2 is relatively located below the stove 6; the smoke sensor is an existing infrared smoke sensor, and an infrared transmitter and an infrared receiver are arranged inside.
[0030] Since a large amount of condensed oil and condensed water will be generated at the same time when it is directly opposite to the oil smoke inhalation direction, in order to extend the service life of the smoke sensor 3, it is necessary to prevent condensed water and condensed oil from entering the interior. An oil leakage port 41 is set at the bottom of the smoke collection pipe so that the oil smoke can smoothly enter the smoke sensor 3, while condensed oil and condensed water will not enter the smoke sensor 3, which greatly extends the service life of the smoke sensor 3. The entire smoke sensor assembly is set in the middle of the bellows. The smoke sensor 3 will feed back the size of the received smoke to the control center, and then adjust the fan air volume according to the value of the smoke volume. The user does not need to frequently adjust the fan air volume during use.
[0031] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
