Description
Technical Field
[0001] This utility model belongs to the field of household appliance technology, and more specifically, it relates to a knob-type intelligent thermostat. Background Technology
[0002] Rotary thermostats are core components for temperature control in household appliances, combining the intuitive operation of traditional mechanical knobs with precise temperature control. Their core consists of physical interaction components and an intelligent temperature control module. Physical knobs often feature clear temperature markings, and some are designed with damping structures to prevent loosening or shifting. Rotary thermostats are easy to operate, even for the elderly and children, and often include safety features such as anti-accidental touch locking and overload protection. They are compatible with various appliances such as heaters, electric ovens, and thermostatic humidifiers, making them a high-performance component that balances practical operation with modern temperature control needs.
[0003] The existing application number is CN201920654001.6. This utility model relates to the field of HVAC and intelligent control technology, specifically disclosing a rotary intelligent thermostat, including a display unit, a knob unit, a housing unit, and a relay unit. The display unit and knob unit have a circular shape and a simple and elegant appearance. The knob unit performs rotation adjustment, and the display unit has both display and button functions. The thermostat is operated and controlled by recording the user's knob and press actions through a hollow rotary encoder inside the thermostat. The knob unit contains a display component, achieving the function of a small encoder supporting a large display component within the limited structural space of the thermostat. Furthermore, based on the above-mentioned rotary intelligent thermostat structure, this utility model proposes a control method for controlling and adjusting air conditioning temperature and fan speed using the thermostat of this utility model.
[0004] Based on the above, when using existing rotary thermostats, since the user's line of sight is generally above the knob, the user's line of sight, the knob pointer, and the scale are prone to misalignment, resulting in inaccurate temperature control and affecting the thermostat's performance. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a rotary intelligent thermostat, which solves the problem that in existing rotary thermostats, the user's line of sight is generally positioned above the knob, which can easily cause misalignment between the user's line of sight, the knob pointer, and the scale, resulting in inaccurate temperature control and affecting the thermostat's performance.
[0006] The purpose and function of this utility model, a knob-type intelligent temperature controller, are achieved by the following specific technical means:
[0007] A rotary intelligent temperature controller includes a controller housing, a temperature sensor, a support ramp, a dial, a temperature control knob, an anti-accidental touch fixing rod, an anti-accidental touch mechanism, and a blind operation auxiliary mechanism. The controller housing houses a microcontroller chip and an execution drive unit, with the execution drive unit externally connected to a heating element. The temperature sensor is connected to the signal input terminal of the microcontroller chip via a wire and is located inside the oven. The support ramp is fixedly connected to the front of the controller housing, and its upper end has an inclined surface structure. The dial... Two sets of scales are provided, each fixedly connected to the front of the inclined plane of the support platform; two sets of temperature control knobs are provided, each rotatably connected to the front of the inclined plane of the support platform, and each set of temperature control knobs has a pointer structure at the lower outer periphery; two sets of anti-accidental touch fixing rods are provided, each fixedly connected to the front of the inclined plane of the support platform, and each set of anti-accidental touch fixing rods is located inside the temperature control knob; the anti-accidental touch mechanism is located inside the temperature control knob; the blind operation auxiliary mechanism is located below the inner side of the temperature control knob.
[0008] Furthermore, the anti-accidental touch mechanism includes: a locking plate and an anti-accidental touch locking groove; the locking plate is fixedly connected to the top of the anti-accidental touch fixing rod; multiple sets of anti-accidental touch locking grooves are provided, and the multiple sets of anti-accidental touch locking grooves are respectively opened on the outside of the locking plate.
[0009] Furthermore, the anti-accidental touch mechanism also includes: a locking guide, a first locking block, and a second locking block; the locking guide is fixedly connected to the upper inner side of the temperature control knob; the first locking block is slidably connected to the lower inner side of the locking guide; the second locking block is slidably connected to the upper side of the temperature control knob, and the second locking block and the first locking block together form a wedge structure.
[0010] Furthermore, the anti-accidental touch mechanism also includes a locking connecting spring; the locking connecting spring is fixedly connected above the first locking block, and the upper end of the locking connecting spring is fixedly connected to the temperature control knob.
[0011] Furthermore, the blind operation auxiliary mechanism includes: a blind operation trigger; the blind operation trigger is provided in multiple sets, and the multiple sets of blind operation triggers are respectively fixedly connected to the front of the inclined plane of the support platform. The multiple sets of blind operation triggers are all arc-shaped structures, and the upper ends of the multiple sets of blind operation triggers are all inclined plane structures.
[0012] Furthermore, the blind operation auxiliary mechanism also includes: blind operation contact components and blind operation elastic components; the blind operation contact components are provided in multiple sets, each set being a metal plate structure, and each set being fixedly connected to the front of the inclined plane of the support platform, each set corresponding to a scale position on the dial, and each set having a different thickness; the blind operation elastic component is an elastic metal structure, fixedly connected to the lower inner side of the temperature control knob, and corresponding to the pointer structure position of the temperature control knob.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention features an anti-accidental touch mechanism. When the user presses the second locking block, it is squeezed inward, pressing the first locking block. The first locking block is then squeezed upward, disengaging from the anti-accidental touch locking groove. At this point, the temperature control knob can rotate normally to regulate the temperature, achieving mechanical temperature control. Once the temperature adjustment is complete, as the user releases the second locking block, the first locking block re-inserts into the anti-accidental touch locking groove under the action of the locking spring, thus limiting the temperature control knob and preventing accidental touch, thereby improving the overall performance of the temperature controller.
[0015] This invention utilizes an anti-accidental touch mechanism. A temperature sensor collects the actual temperature inside the appliance or in the environment in real time, converting physical temperature signals, such as heat changes, into electrical signals recognizable by a microcontroller chip. This signal is continuously transmitted to the microcontroller chip. The microcontroller chip receives the target temperature set by the user via a temperature control knob and the actual temperature signal from the temperature sensor. Using built-in algorithms such as temperature difference comparison and PID control, it calculates the deviation between the two, determines whether heating or cooling is needed, and generates corresponding control commands. The execution drive unit receives these control commands from the microcontroller chip and, through driving relays, thyristors, motors, and other components, adjusts the operating state of the appliance's heating module (such as a heating element) or cooling module (such as a compressor), thus achieving intelligent temperature control of the appliance.
[0016] This invention utilizes a blind operation auxiliary mechanism. When the temperature control knob is operated, the rotation of the knob causes the blind operation elastic element to rotate, bringing it into contact with the blind operation trigger. At this point, the elastic element is pushed upwards by the trigger. Once the elastic element disengages from the trigger, its own material elasticity causes it to rapidly reset and contact the blind operation contact, producing a sound. Because the height of the blind operation contact varies, the sound produced when the elastic element contacts different positions of the blind operation contact varies. With practice, users can judge the temperature controlled by the knob by sound. The inclined design of the support platform also facilitates user adjustment. The observation of the dial scale enables blind operation of the temperature control knob. Through the squeezing and resetting actions of the blind operation elastic element and the blind operation trigger element as the knob is rotated, as well as the differentiated sounds produced by contacting the blind operation contact elements at different heights, users can judge the temperature setting by sound alone without focusing their eyes on the knob. With practice, users can accurately adjust the temperature even when their hands are busy (such as when operating appliances in the kitchen) or in situations where visibility is limited, such as low light. This reduces the operational threshold and attention consumption. The tilt setting of the support platform optimizes the dial observation experience, allowing users to clearly see the scale without deliberately adjusting their viewing angle, reducing reading errors caused by viewing angle deviation, further improving the accuracy of temperature setting and user comfort, and enhancing the overall performance of the thermostat.

[0030] The anti-accidental touch mechanism also includes a locking connection spring 106; the locking connection spring 106 is fixedly connected above the first locking block 104, and the upper end of the locking connection spring 106 is fixedly connected to the temperature control knob 5.
[0031] The specific usage and function of this embodiment are as follows: When the user operates the temperature control knob 5, the user first presses the second locking block 105. The second locking block 105 is squeezed inward, pressing the first locking block 104. The first locking block 104 is squeezed upward, disengaging from the anti-accidental touch locking groove 102.

[0032] Example 2:
[0033] This utility model provides a knob-type intelligent temperature controller, based on Embodiment 1, such as... Figures 1 to 5 As shown, it also includes a blind operation assistance mechanism, which is located on the inner side of the temperature control knob 5.
[0034] The blind operation auxiliary mechanism includes: a blind operation trigger 501; multiple sets of blind operation triggers 501 are provided, and the multiple sets of blind operation triggers 501 are fixedly connected to the front of the inclined plane of the support inclined platform 3.
