Description

Technical Field

[0001] This utility model belongs to the field of integrated stove technology, and in particular relates to an integrated stove with a fall detection alarm function. Background Technology

[0002] An integrated cooktop is a kitchen appliance that combines multiple functions such as a range hood, gas stove, disinfection cabinet, and storage cabinet. It has advantages such as saving space, good smoke extraction, energy saving, low consumption, and environmental protection.

[0003] Existing integrated cooktops typically have a support plate on the cooktop panel. The pot support is installed on the support plate and supported by the support plate. The support plate is fixed to the burner base with bolts, which requires tools for disassembly and assembly. This is laborious, inconvenient, and inefficient. Moreover, after a period of time, the surface of the bolts becomes contaminated with oil, affecting normal disassembly and assembly.

[0004] The existing patent document "An Integrated Cooktop" (Announcement No.: CN220707417U) discloses "a drip tray supporting a pot bracket, the drip tray being supported and fitted with the upper surface of the cabinet countertop, and screws passing through the drip tray and engaging with the burner head", which also has the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide an integrated stove with a fall detection alarm function. It has a novel structure and replaces the bolt connection fixing method used in the prior art for mounting the pot bracket. The support plate is quick to disassemble and assemble, saving time and effort, and can also avoid the problem of bolts being affected by oil pollution and thus affecting normal disassembly and assembly.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An integrated stove with a fall detection alarm function includes: a stove body, a stove panel, and a burner. The stove panel has a fixing through hole, and a support plate is connected to the fixing through hole. The support plate has a central hole for the burner to pass through. The key feature is that: connecting parts are symmetrically distributed on the bottom surface of the support plate; the burner base has an outer edge with a limiting through hole that mates with the connecting parts; the connecting parts include a shaft and elastic extension blocks, the elastic extension blocks are distributed around the shaft, and a latch is provided on the outer side of the elastic extension blocks; the latch passes through the limiting through hole to prevent the connecting parts from freely disengaging from the limiting through hole, thus limiting the support plate to the burner base. This integrated stove has a novel structure, replacing the bolted connection method used in existing technologies for mounting pot supports. The support plate is quick and easy to install and remove, saving time and effort, and avoiding the problem of bolts being affected by oil contamination during installation.

[0008] Furthermore, the support plate is recessed downwards to form a recessed part, which improves the rigidity and deformation resistance of the support plate. The connector is located on the recessed part, which increases the distance between the connector and the burner outlet, thereby reducing the thermal damage to the connector caused by flame heat radiation.

[0009] Furthermore, the recessed portion is provided with a mounting through hole, and the connector is welded and fixed in the mounting through hole. The mounting through hole facilitates the positioning and installation of the connector and increases the contact area between the connector and the recessed portion, thereby improving the installation strength of the connector.

[0010] Furthermore, the support plate is equipped with positioning grooves that correspond to the feet of the pot support, enabling the pot support to be quickly positioned on the support plate, reducing the difficulty of positioning, and the pot support cannot slide freely, resulting in high installation stability.

[0011] Furthermore, an extension is provided on the bottom surface of the outer edge, and the limiting through hole extends downward to pass through the extension, increasing the depth of the limiting through hole, which can be adapted to longer connectors to improve the reliability of the connection.

[0012] Furthermore, it also includes a fall detection device, which comprises a millimeter-wave radar, a battery, and an alarm module. The battery is electrically connected to the millimeter-wave radar and the alarm module. The alarm module has a built-in buzzer circuit. The millimeter-wave radar is installed on the front bottom surface of the cooktop panel. The millimeter-wave radar includes a MIMO antenna, a millimeter-wave transceiver front-end unit, a millimeter-wave main control processing unit, and an IoT communication module. The MIMO antenna is electrically connected to the millimeter-wave transceiver front-end unit, the millimeter-wave transceiver front-end unit is electrically connected to the millimeter-wave main control processing unit, the millimeter-wave main control processing unit is electrically connected to the alarm module, and the millimeter-wave main control processing unit communicates with the cloud platform through the IoT communication module.

[0013] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0014] When installing the support plate, press the elastic extension block inward, causing the latch to move inward and pass through the limiting through hole on the outer edge. After the latch passes through the limiting through hole, the latch follows the elastic extension block and unfolds outward, pressing against the bottom surface of the outer edge. This restricts the elastic extension block from freely moving upward out of the limiting through hole. At this time, the bottom surface of the recessed part is attached to the top surface of the outer edge, and the connector cannot move up and down, thus fixing the support plate to the burner base. Pulling the support plate upward can separate the support plate from the outer edge, replacing the existing bolt connection method for the support plate. This method is quick to install and remove, saves time and effort, and avoids the problem of bolts being affected by oil contamination during normal installation and removal.

Detailed Implementation

[0024] like Figures 1 to 6 As shown, this utility model discloses an integrated stove with a fall detection alarm function, comprising: a stove body 1, a stove panel 2, a burner, and a fall detection device. The stove panel 2 and the burner are installed on the top of the stove body 1. The stove panel 2 has a fixing through hole, and a support plate 4 is connected to the fixing through hole. The center of the support plate 4 has a central hole for the burner to pass through, and the support plate 4 has a positioning groove 5 corresponding to the support leg 16 of the pot support.

[0025] Insert the pot support legs 16 into the positioning grooves 5 to achieve quick positioning of the pot support on the support plate 4, reducing the positioning difficulty, and the pot support cannot slide freely, resulting in high installation stability.

[0026] The support plate 4 has a recessed part 6 formed by a downward indentation in the middle, and the central hole is located in the center of the recessed part 6. The recessed part 6 improves the rigidity and deformation resistance of the support plate 4.

[0027] The recessed portion 6 has symmetrically distributed mounting through holes 7, each containing a connector 8. The connector 8 can be made of aluminum alloy. The mounting through holes 7 facilitate the positioning and installation of the connector 8, and also increase the contact area between the connector 8 and the recessed portion 6, thereby improving the installation strength of the connector 8. The connector 8's placement on the recessed portion 6 increases the distance between the connector 8 and the burner's flame outlet, thus reducing the thermal damage caused by flame heat radiation to the connector 8.

[0028] The burner base 9 has an outer edge 10, and the outer edge 10 has a limiting through hole 11 that is connected to the connector 8. The connector 8 includes a shaft portion 12 with a central through hole and an elastic extension block 13. The upper end of the shaft portion 12 is welded and fixed in the mounting through hole 7, and is securely fixed. The elastic extension block 13 is distributed around the lower end face of the shaft portion 12. The outer side of the elastic extension block 13 has a latch portion 14, and the cross-sectional shape of the latch portion 14 is triangular.

[0029] When installing the support plate 4, the elastic extension block 13 is pressed inward, causing the latch 14 to move inward and pass through the limiting through hole 11. The shaft 12 is located in the limiting through hole 11. After the latch 14 passes through the limiting through hole 11, the latch 14 follows the elastic extension block 13 and unfolds outward. The latch 14 abuts against the bottom surface of the outer edge 10, thereby restricting the elastic extension block 13 from freely coming out of the limiting through hole 11. At this time, the bottom surface of the recess 6 is attached to the top surface of the outer edge 10, and the connector 8 cannot move up and down, thus fixing the support plate 4 to the burner base 9. Pulling the support plate 4 upward can separate the support plate 4 from the outer edge 10, replacing the existing bolt connection method of the support plate 4. This method is quick to install and remove, saves time and effort, and avoids the problem of bolts being affected by oil contamination.

[0030] An extension 15 is provided on the bottom surface of the outer edge 10, and the limiting through hole 11 extends downward to pass through the extension 15, increasing the depth of the limiting through hole 11, which can be adapted to longer connectors 8 to improve the reliability of the connection.

[0031] The fall detection device includes a millimeter-wave radar 17, a battery, and an alarm module. The battery is electrically connected to the millimeter-wave radar 17 and the alarm module. The alarm module has a built-in buzzer circuit. The millimeter-wave radar 17 is installed on the front bottom surface of the cooktop panel 2. The battery and the alarm module are installed in the inner cavity of the cooktop panel 2. The millimeter-wave radar 17 includes a MIMO antenna, a millimeter-wave transceiver front-end unit, a millimeter-wave main control processing unit, and an IoT communication module. The MIMO antenna is electrically connected to the millimeter-wave transceiver front-end unit, which is electrically connected to the millimeter-wave main control processing unit. The millimeter-wave main control processing unit is electrically connected to the alarm module. The millimeter-wave main control processing unit communicates with the cloud platform through the IoT communication module. The IoT communication module can be a 4G / 5G communication module or a WIFI communication module. The chip model of the millimeter-wave main control processing unit is IWR6843AOP. The millimeter-wave radar 17 is existing technology.

[0032] The millimeter-wave transceiver front-end unit transmits and receives signals via a MIMO antenna and transmits the received raw ADC data to the millimeter-wave main control processing unit for processing and judgment. When a person appears in the detection area, the millimeter-wave radar 17 generates point cloud data and track information. When the point cloud and track show a change in altitude difference and remain stationary for a set time, it is judged that a person has fallen. The millimeter-wave main control processing unit sends an electrical signal to the alarm module, causing it to emit an audible warning and send the alarm information to the cloud platform. The cloud platform then sends the alarm information to the user's mobile APP, enabling remote monitoring and solving the problem of elderly people accidentally falling in the kitchen.

[0033] The MIMO antenna has an azimuth and elevation angle of ±60°, which can form a relatively wide detection angle.

[0034] like Figure 7 As shown, the GPIO interface of the millimeter-wave main control processing unit is connected to the base (b) of transistor Q1 through resistor R2. Resistor R1 and capacitor C1 are connected in parallel before resistor R2. The emitter (e) of transistor Q1 is grounded, and the collector (c) of transistor Q1 is connected to the alarm module through resistor R3. When the GPIO port of the millimeter-wave main control processing unit outputs a high level, the alarm module emits an audible alarm; when the GPIO port of the millimeter-wave main control processing unit outputs a low level, the alarm module is in a silent state.

[0035] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
