[0043] A preferred embodiment is given below, and the present disclosure is described more clearly and completely in conjunction with the accompanying drawings.

[0044] Example 1

[0045] In a specific embodiment of the present disclosure, a non-contact temperature measurement mechanism 100 is provided. Figure 1 As shown, the non-contact temperature measurement mechanism 100 includes a temperature measurement structure 1 and a position adjustment structure 2, and the non-contact temperature measurement mechanism 100 is arranged at a preset position on the smart home appliance;

[0046] The temperature measuring structure 1 is movably arranged on the position adjusting structure 2;

[0047] Applying a force in a preset direction to the temperature measurement structure 1 by external operation to move the temperature measurement structure 1 to a set position on the position adjustment structure 2;

[0048] The temperature measurement structure 1 is used to collect temperature data of a target collection area corresponding to a set position on the smart home appliance.

[0049] Specifically, the temperature measurement structure 1 can be a non-contact temperature measurement module, for example, an infrared temperature measurement module, which can perform precise temperature measurement, and the position adjustment structure 2 can be a connecting component such as a guide rail, a slide rail, or a slideway for the temperature measurement structure 1 to move.

[0050] By setting the position adjustment structure 2 at a preset position of the smart home appliance, for example, setting the position adjustment structure 2 on the smoke collecting chamber panel of the range hood corresponding to the stove, or setting the position adjustment structure 2 on the wall corresponding to the stove, etc., the temperature measurement structure 1 is moved to the set position along the preset direction under the action of the external force, so that the temperature measurement structure 1 can collect the temperature data of the target collection area corresponding to the set position on the smart home appliance, such as the user manually moves the temperature measurement structure 1 to the top of the stove core area, so that the temperature measurement structure 1 collects the temperature data of the stove core area. Among them, the movable area of ​​the position adjustment structure 2 should not be less than the range covered by the target collection area.

[0051] This specific implementation method adjusts the temperature collection area of ​​the temperature measurement structure through the position adjustment structure, which can meet the temperature measurement requirements of multiple stove cores by one non-contact temperature measurement probe.

[0052] In a specific embodiment, Figure 2 As shown, the temperature measurement structure 1 includes a locking structure 11 and a temperature acquisition unit 12 disposed on the locking structure 11;

[0053] The temperature measuring structure 1 is movably arranged on the position adjusting structure 2 through a locking structure 11;

[0054] The temperature collection unit 12 is used to collect temperature data;

[0055] The locking structure 11 is used to lock at a set position on the position adjustment structure 2 to fix the temperature measurement structure 1 .

[0056] Among them, the locking structure 11 includes a limit assembly 111 and a locking assembly 112; the position adjustment structure 2 includes a guide rail; the limit assembly 111 is sleeved on the guide rail; the limit assembly 111 is connected to the locking assembly 112; the locking assembly 112 locks the limit assembly 111 to fix the temperature measurement structure 1, and the locking assembly 112 unlocks the limit assembly 111 to make the temperature measurement structure 1 in a movable state.

[0057] Specifically, in order to prevent the temperature measurement structure 1 from sliding during the temperature collection process, causing the temperature collection area to deviate from the target collection area, and to ensure the accuracy of the temperature data, the temperature collection unit 1211 can be set on the position adjustment structure 2 through the limiting component 111 of the locking structure 11, and then the limiting component 111 can be locked by the locking component 112 of the locking structure 11, so that the temperature measurement structure 1 can be fixed at the set position on the position adjustment structure 2.

[0058] For example, a clamp composed of a pipe and a screw (for example, a set screw) is used as the locking structure 11, the temperature acquisition unit 12 is set above the clamp, and the pipe of the clamp is sleeved on the guide rail. When the user needs to move the temperature measurement structure 1, first check whether the clamp is in an unlocked state. If not, the clamp must be unlocked by screws so that there is a certain gap between the pipe and the guide rail, so that the temperature measurement structure 1 can be moved on the guide rail; when the user moves the temperature measurement structure 1 to the set position, the clamp is locked by screws to prevent the temperature measurement structure 1 from moving during the temperature acquisition process.

[0059] Of course, other locking structures 11 may also be used, and this specific embodiment does not limit this.

[0060] In a specific embodiment, the position adjustment structure 2 includes a plurality of guide rails, wherein at least one guide rail is provided with a locking structure 11 .

[0061] Specifically, the guide rail may be one or more. For example, the temperature measurement structure 1 is set on a guide rail through the locking structure 11 to slide, or two guide rails are set in parallel to form a track, and the temperature measurement structure 1 is placed on the track through the locking structure 11 to slide. The guide rail includes a metal cylindrical guide rail or a special-shaped guide rail. For example, for a three-burner stove, in order to improve the accuracy of the temperature data collected by the temperature measurement structure 1, a special-shaped guide rail is set so that the temperature measurement structure 1 can move along the special-shaped guide rail to the top of each stove core area to collect temperature data.

[0062] In order to reduce the complexity of the operation, the locking structure 11 can be sleeved on only one guide rail, and the connection between the temperature measurement structure 1 and other guide rails only serves as a support, without the locking structure 11.

[0063] In a specific embodiment, Figure 3-4 The temperature measurement structure 1 is provided with an indication module 13;

[0064] The indication module 13 is used to emit an indication light source to the operation area of ​​the smart home appliance to form a light spot indication area;

[0065] The overlapping range between the light spot indication area and the target acquisition area is greater than a preset threshold.

[0066] Specifically, in order to enable the user to intuitively perceive the area where the temperature measurement structure 1 collects temperature, an indication module 13 may be further provided on the temperature measurement structure 1, and through optical path calibration, the indication module 13 and the temperature measurement structure 1 are installed at a certain spacing, and the light spot indication area formed by the indication module 13 emitting an indication light source (for example, a laser, a collimated light source) at a limited length coincides with the temperature collection area of ​​the temperature measurement structure 1, and the installation spacing is fixed.

[0067] Among them, the limited length refers to the distance from the smart home appliance at a preset position. For example, if the non-contact temperature measurement mechanism 100 is set on the range hood, the limited length refers to the installation height of the range hood. For example, the recommended installation height of a European-style range hood is 700 mm; the installation spacing refers to the spacing between the probe of the indicating module 13 and the probe of the temperature measurement structure 1, for example, 0.5 cm, 2 cm or others. The smaller the spacing, the closer the center of the indicating module 13 and the center of the temperature measurement structure 1 are at the limited height, and the higher the accuracy. When the limited height is far enough and the spacing between the indicating module 13 and the temperature measurement structure 1 is close enough, it is considered that the center of the indicating module 13 and the center of the temperature measurement structure 1 coincide at the limited distance.

[0068] When the user is moving the temperature measurement structure 1, the indication module 13 can be activated to emit an indication light source to indicate the temperature collection area of ​​the temperature measurement structure 1 in real time. Of course, the user can also directly move the temperature measurement structure 1 to the corresponding position, and then activate the indication module 13 to emit an indication light source to verify whether the position meets the expected temperature collection area.

[0069] This embodiment adjusts the temperature collection area of ​​the temperature measurement structure through the position adjustment structure, which can meet the temperature measurement requirements of multiple stove cores by one non-contact temperature measurement probe, and indicates the temperature measurement area through the indicating light source, so that the user can perceive the temperature collection area of ​​the non-contact temperature measurement probe in the usage scenario, thereby improving the user's cooking experience.

[0070] Example 2

[0071] In a specific embodiment of the present disclosure, a range hood 200 is provided, such as Figure 5 As shown, the range hood 200 includes the non-contact temperature measuring mechanism 100 of Example 1.

[0072] Specifically, the position adjustment structure 2 of the non-contact temperature measurement mechanism 100 can be embedded and installed on the smoke collecting chamber panel 3 corresponding to the stove core area, and the temperature data of different stove core areas can be collected by moving the position of the temperature measurement structure 1.

[0073] In a specific embodiment, the smoke machine 200 further includes a light filtering component;

[0074] The temperature measurement structure 1 of the non-contact temperature measurement mechanism 100 collects temperature data of the target collection area through the filter component, wherein the filter component includes one or more filters.

[0075] Specifically, the non-contact temperature measuring mechanism 100 can be sealed in the smoke collecting chamber through a filter. For example, a groove is provided on the smoke collecting chamber panel 3, and a track consisting of two guide rails is provided in the groove for the non-contact temperature measuring mechanism 100 to move in the groove. The temperature measuring structure 1 on the non-contact temperature measuring mechanism 100 measures the temperature of the target collection area through the central area of ​​the track. A whole filter is installed above the cooker and below the temperature measuring structure 1, corresponding to the central area of ​​the track, so that the temperature measurement optical path can pass through the filter to reach the temperature measurement structure 1, which not only ensures the realization of the temperature measurement function, but also makes the surface smooth and flat, and easy to clean.

[0076] Among them, multiple non-contact temperature measurement mechanisms 100 can also be set on the smoke collection chamber panel 3 of the range hood 200 to collect temperature data of multiple target collection areas at the same time. The user can adjust the position of the temperature measurement structure 1 through the contact part between the temperature measurement structure 1 and the guide rail.

[0077] In addition, in order to reduce costs, the filter can be installed at the smoke collecting chamber panel 3 corresponding to the stove core area. For example, for a stove with two stove cores, only two independent filters can be set at the smoke collecting chamber panels 3 corresponding to the two stove core areas, and the central area of ​​other tracks is still sealed by the smoke collecting chamber panel 3 of the range hood 200, so that the temperature measurement structure 1 can collect the temperature data of the stove core area through the filter at this position.

[0078] This embodiment adjusts the temperature collection area of ​​the temperature measurement structure through the position adjustment structure, which can meet the temperature measurement requirements of multiple stove cores by one non-contact temperature measurement probe, and indicates the temperature measurement area through the indicator light source, so that the user can perceive the temperature collection area of ​​the non-contact temperature measurement probe in the use scenario, thereby improving the user's cooking experience. In addition, the non-contact temperature measurement probe is sealed in the smoke collection chamber by using a filter component, so that the structure of the non-contact temperature measurement mechanism is flat, easy to clean, and does not affect the appearance of the range hood.

[0079] In addition, the relevant operations of the computer program in the present disclosure are all realized by the inherent functions of the selected hardware devices and do not belong to the technical content to be protected by the present disclosure.

[0080] Although the specific embodiments of the present disclosure are described above, those skilled in the art should understand that this is only an example, and the protection scope of the present disclosure is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present disclosure, but these changes and modifications all fall within the protection scope of the present disclosure.
