Description

Technical Field

[0001] The utility model relates to the field of household electrical appliances, in particular to an electric hot pot. Background Art

[0002] Electric cookers such as electric baking trays, electric hot pots, and electric frying pans all require a thermostat to control the temperature. The temperature is adjusted by turning the knob switch on the thermostat. Currently, the knob switch is usually very smooth when turned, with almost no resistance. Users have a weak intuitive perception of temperature changes, and there is no feedback when the knob switch is rotated. During use, the gear scale printed on the pot body is needed to determine whether the gear is successfully switched. The actual temperature adjustment range is difficult to determine, which can easily lead to errors in temperature gear adjustment and a poor user experience.

[0003] In the prior art, by adding a sound-generating structure, the knob switch makes a sound and vibrates during the rotation process, thereby providing feedback to the user. For example, the prior art CN217243848U discloses a thermostat for electric heating cookers, including a thermostat body and a knob, wherein the knob can be rotatably and adjustably mounted on the front of the thermostat body, a circle of latch teeth is arranged on the back of the knob, and there are tooth grooves between adjacent latch teeth, and a top that can move up and down is arranged on the thermostat body, and the top of the top is against the tooth groove between two adjacent latch teeth. When the knob is turned, the cooperation between the top and the latch teeth can provide a certain resistance, and when the knob is turned, a sound can be made between the top and the latch teeth, which plays a certain role of a prompt sound. However, in actual use, the sound between the top and the latch teeth is uniform, and it is difficult to further feedback the temperature adjustment amplitude and direction. Utility Model Content

[0004] The purpose to be achieved by the utility model is to provide an electric hot pot, which solves the problem in the prior art that the sound emitted when rotating the adjustment knob cannot feedback the temperature adjustment amplitude and direction, and feedbacks the temperature adjustment amplitude and direction to provide a better user experience.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electric hot pot, comprising a pot body, a heating tube arranged on the pot body, and an adjustable temperature controller, the adjustable temperature controller is used to control the working temperature of the heating tube, the adjustable temperature controller comprises an adjusting knob located on the outside of the pot body, the adjusting knob is provided with an actuating member that rotates with the adjusting knob and can move axially relative to the adjusting knob, the actuating member maintains a tendency to move away from the adjusting knob, the outer side surface of the pot body is provided with a plurality of strip-shaped grooves, the strip-shaped grooves are arranged and distributed in sequence along the movement trajectory of the actuating member, the actuating member falls into the strip-shaped grooves following the rotation of the adjusting knob and produces a knocking sound, and the width and / or depth of the grooves changes along the positive movement trajectory of the actuating member.

[0006] After adopting the above technical scheme, the utility model has the following advantages: when the user adjusts the temperature, the adjustment knob is rotated, so that the action piece follows the adjustment knob to rotate and continuously move out and fall into the strip groove, and the user's hand can also feel the impact vibration when the action piece hits, and can also hear the impact sound generated by the action piece. Among them, the width of the strip groove is set to change along the positive movement trajectory of the action piece, and the frequency of the impact sound generated during the rotation process changes. The depth of the strip groove is set to change along the positive movement trajectory of the action piece, and the tone of the impact sound generated during the rotation process changes. Therefore, when the user rotates the adjustment knob to adjust the temperature, the frequency and tone of the impact sound can feedback the user's temperature adjustment amplitude and direction. The user can directly perceive the temperature adjustment change from the senses, control the temperature change more accurately, and can timely understand the temperature change trend without looking at the gear scale on the pot body, making the electric hot pot more convenient and intuitive during use, and improving the user's experience.

[0007] Furthermore, the width of the strip groove gradually decreases or increases along the forward motion trajectory of the actuating member. With the above technical solution, the width of the strip groove gradually decreases, and the impact sound produced by the actuating member and the groove gradually becomes more rapid; the width of the strip groove gradually increases, and the impact sound produced by the actuating member and the groove gradually becomes more gentle. By identifying the frequency change of the impact sound, the amplitude and direction of the temperature adjustment can be known, which improves the user experience.

[0008] Furthermore, the depth of the strip-shaped groove gradually decreases or increases along the forward motion trajectory of the actuating member. With the aforementioned technical solution, as the depth of the strip-shaped groove gradually decreases, the pitch of the impact sound produced by the actuating member colliding with the groove gradually becomes higher; as the depth of the strip-shaped groove gradually increases, the pitch of the impact sound produced by the actuating member colliding with the groove gradually becomes lower. By identifying the change in the pitch of the impact sound, the amplitude and direction of the temperature adjustment can be known, thereby improving the user experience.

[0009] Furthermore, the outer side surface of the pot body is concave to form a strip-shaped groove. The above-mentioned technical solution is used to form a strip-shaped groove, which is convenient for production and processing, and can also enhance the structural strength of the pot body near the adjustment knob and improve the durability of the pot body.

[0010] Alternatively, the outer side surface of the pot body is provided with a plurality of raised strip-shaped ribs, and a strip-shaped groove is formed between two adjacent strip-shaped ribs. With the above-mentioned technical solution, the friction between the strip-shaped ribs and the actuating member is more obvious, which is conducive to the obvious impact sound produced by the collision between the actuating member and the strip-shaped ribs. The user's hand can clearly feel the jumping feeling when the actuating member slides over the strip-shaped groove. The user can perceive the temperature change through hearing and auditory sense, which improves the convenience of use. The raised strip-shaped ribs can increase the structural strength of the outer side surface of the pot body, improve the durability and impact resistance of the electric hot pot, and the strip-shaped groove formed between the two strip-shaped ribs has openings at both ends, which is easy to clean, can reduce the adhesion of food residues and stains, help reduce bacterial growth, and ensure the user's hygienic use.

[0011] Furthermore, the adjusting knob is provided with a mounting blind hole opening toward the strip-shaped groove, and an elastic member is provided in the mounting blind hole, and the elastic member abuts against the actuating member to keep the actuating member away from the adjusting knob. With the aforementioned technical solution, the actuating member is stably fixed on the adjusting knob through the cooperation of the mounting blind hole and the elastic member, and keeps the actuating member away from the adjusting knob, thereby ensuring that the actuating member can accurately follow the rotation of the adjusting knob during the rotation process, and avoiding the actuating member from falling off during the assembly or rotation process. The elastic member also has a buffering effect, reduces the wear on the actuating member, and increases the service life of the actuating member. The elastic member and the actuating member are also convenient for assembly, disassembly and replacement.

[0012] Furthermore, the action piece includes a ball head and a connecting rod, the ball head abuts against the strip groove, and the connecting rod is connected to the elastic piece. With the above technical solution, the ball head abuts against the strip groove, so that the contact point between the action piece and the strip groove during rotation is more accurate, which is conducive to the user's more accurate perception of temperature changes. The connecting rod is connected to the elastic piece to ensure the stability of the action piece and ensure that the action piece will not fall off as the adjustment knob rotates, thereby improving the reliability of the action piece. The ball head can also reduce the resistance when the adjustment knob rotates.

[0013] Furthermore, the action piece is a sphere, and one end of the elastic piece abuts against the surface of the sphere that is opposite to the strip groove. With the above-mentioned technical solution, the action piece is a sphere, and the contact point with the strip groove is more precise, which improves the perception of temperature adjustment changes. The sphere makes the impact sound more concentrated, which helps the user to more accurately judge the amplitude and direction of temperature adjustment. The contact area between the sphere and the strip groove is small, thereby reducing friction, helping to reduce the wear of the action piece and the strip groove, extending the service life of the electric hot pot, and reducing production costs. The sphere can rotate when the adjustment knob is rotated, converting sliding friction into rolling friction, reducing the resistance when the adjustment knob is rotated.

[0014] Furthermore, the elastic member is a conical helical spring, the end of the conical helical spring with a larger diameter is clamped in the installation blind hole, and the end with a smaller diameter is abutted against the actuating member. The above technical solution ensures that the elastic member can be stably installed in the installation blind hole, drives the actuating member to rotate with the adjusting knob in a long-term and stable manner, ensures that the actuating member is stably connected to the conical helical spring, and prevents the actuating member from falling off during rotation.

[0015] Furthermore, a receiving groove is provided on the outer side of the pot body, the adjusting knob is installed in the receiving groove, and the strip groove is provided on the bottom surface of the receiving groove. With the above technical solution, the receiving groove limits the adjusting knob, ensures the stability of the adjusting knob, fixes the adjusting knob on the outside of the pot body, and also provides an installation guide for the adjusting knob, which is convenient for quick assembly. The strip groove is provided on the bottom surface of the receiving groove and cooperates with the adjusting knob to produce a knocking sound to feedback the user's temperature adjustment range and direction.

[0016] Furthermore, the angle range of the strip groove distribution is 180°. The above technical solution can provide a wider temperature adjustment range, so that users can choose different temperatures according to their needs. Users can judge the amplitude and direction of temperature adjustment through the impact sounds at different positions, thereby controlling the temperature more accurately.

[0026] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0027] like Figures 1 to 6 As shown, the utility model provides an electric hot pot, comprising a pot body 1 and a heating tube arranged on the pot body 1, and an adjustable temperature controller 2, the adjustable temperature controller 2 is used to control the working temperature of the heating tube, the adjustable temperature controller 2 comprises an adjusting knob 21 located on the outside of the pot body 1, an actuating member 22 is provided on the adjusting knob 21, which rotates with the adjusting knob 21 and can move axially relative to the adjusting knob 21, the actuating member 22 keeps a tendency to move away from the adjusting knob 21, a plurality of strip grooves 11 are provided on the outer side surface of the pot body 1, the strip grooves 11 are arranged and distributed in sequence along the movement trajectory of the actuating member 22, the actuating member 22 rotates with the adjusting knob 21 and falls into the strip grooves 11 and generates a knocking sound, and the width D and / or depth H of the strip groove 11 changes along the positive movement trajectory of the actuating member 22.

[0028] In this embodiment, when the user adjusts the temperature, the adjusting knob 21 is rotated, so that the action member 22 follows the adjustment knob 21 and continuously moves out and falls into the strip groove 11. The user's hand can also feel the impact vibration of the action member 22 when it hits, and can also hear the impact sound generated by the action member 22. Among them, the width D of the strip groove 11 is set to change along the positive motion trajectory of the action member 22, and the frequency of the impact sound generated during the rotation process changes. The depth H of the strip groove 11 is set to change along the positive motion trajectory of the action member 22, and the tone of the impact sound generated during the rotation process changes. Therefore, when the user rotates the adjusting knob 21 to adjust the temperature, the frequency and tone of the impact sound can feedback the user's temperature adjustment amplitude and direction. The user can directly perceive the temperature adjustment change from the senses, control the temperature change more accurately, and can timely understand the temperature change trend without looking at the gear scale on the pot body 1, making the electric hot pot more convenient and intuitive during use, and improving the user's use experience.

[0029] The positive motion trajectory of the actuating member 22 refers to the motion direction of the actuating member 22 when the sensing temperature of the adjustable thermostat 2 is increased.

[0030] The strip grooves 11 can be regularly distributed. For example, in order to achieve a regular change in the frequency of the impact sound generated during the rotation process, in one embodiment, the width D of the strip groove 11 is set to gradually decrease along the positive motion trajectory of the action member 22, and the impact sound generated by the action member 22 and the groove gradually becomes more rapid; or, the width D of the groove is set to gradually increase along the positive motion trajectory of the action member 22, and the impact sound generated by the action member 22 and the groove gradually becomes more gentle. By identifying the frequency change of the impact sound, the amplitude and direction of the temperature adjustment can be known, which improves the user experience.

[0031] For another example, in order to achieve a regular change in the pitch of the impact sound generated during the rotation process, in one embodiment, the depth H of the strip groove 11 is set to gradually decrease along the forward motion trajectory of the action member 22, and the pitch of the impact sound generated by the action member 22 and the groove gradually becomes higher; or, the depth H of the strip groove 11 is set to gradually increase along the forward motion trajectory of the action member 22, and the pitch of the impact sound generated by the action member 22 and the groove gradually becomes lower. By identifying the change in the pitch of the impact sound, the amplitude and direction of the temperature adjustment can be known, thereby improving the user experience.

[0032] It is understandable that the above embodiments can be implemented separately to change the frequency and tone of the impact sound separately, or can be implemented simultaneously to change the frequency and tone of the impact sound simultaneously. For example, the width D and depth H of the strip groove 11 are designed to change regularly at the same time. Specifically, Figure 3 , Figure 5As shown, the width D and the depth H of the strip groove 11 at the starting position of the distribution are the largest, and the width D and the depth H of the strip groove 11 at the ending position of the distribution are the smallest. When the adjustment knob 21 is rotated from the starting position to the ending position, the corresponding temperature sensing temperature changes from low to high, the frequency of the impact sound gradually becomes rapid, and the tone of the impact sound gradually increases. The user can know the temperature adjustment amplitude and direction based on the impact sound.

[0033] The reverse change is also feasible. In another embodiment, the width D of the strip groove 11 gradually increases along the positive movement trajectory of the actuating member 22, and the depth H of the strip groove 11 gradually increases along the positive movement trajectory of the actuating member 22. The impact sound gradually becomes gentler, and the tone of the impact sound gradually becomes lower accordingly.

[0034] The strip grooves 11 may also be irregularly distributed, that is, the frequency of the sound produced after the action piece 22 continuously strikes may change irregularly, and the tone may also change irregularly. For example, when the adjusted temperature sensing temperature is within a lower range, the striking sound produced by the rotation of the action piece 22 is gentle and has a lower tone, but the corresponding rotation angle of the action piece 22 is larger. When the adjusted temperature sensing temperature enters a higher range, the striking sound produced by the rotation of the action piece 22 may become rapid and have a higher tone, but the corresponding rotation angle of the action piece 22 is smaller.

[0035] In order to achieve the impact sound produced by the action member 22 hitting the strip-shaped groove 11, in one embodiment, the outer side surface of the pot body 1 is concave to form the strip-shaped groove 11. The concave strip-shaped groove 11 is convenient for production and processing, and can also enhance the structural strength of the pot body 1 near the adjusting knob 21, thereby improving the durability of the pot body 1.

[0036] In another embodiment, the outer side of the pot body 1 is provided with a plurality of raised strip-shaped convex ribs, and a strip-shaped groove 11 is formed between two adjacent strip-shaped convex ribs. The friction between the strip-shaped convex ribs and the action piece 22 is more obvious, which is conducive to the action piece 22 and the strip-shaped convex ribs to produce a clear impact sound, and the user's hand can clearly feel the jumping feeling when the action piece 22 slides over the strip-shaped groove 11. The user can perceive the temperature change through hearing and auditory sense, which improves the convenience of use. The raised strip-shaped convex ribs can increase the structural strength of the outer side of the pot body 1, improve the durability and impact resistance of the electric hot pot, and the strip-shaped groove 11 formed between the two strip-shaped convex ribs is open at both ends, which is easy to clean, can reduce the adhesion of food residues and stains, help reduce bacterial growth, and ensure the user's hygienic use.

[0037] like Figure 4As shown, in order to ensure that the action member 22 keeps a tendency to stay away from the adjusting knob 21, in one embodiment, the adjusting knob 21 is provided with a mounting blind hole 23 opening toward the strip groove 11, and an elastic member 24 is provided in the mounting blind hole 23, and the elastic member 24 abuts against the action member 22 to keep the action member 22 away from the adjusting knob 21. Through the cooperation of the mounting blind hole 23 and the elastic member 24, the action member 22 is stably fixed on the adjusting knob 21 and keeps a tendency to stay away from the adjusting knob 21, ensuring that the action member 22 can accurately follow the rotation of the adjusting knob 21 during the rotation process, and avoiding the action member 22 from falling off during the assembly or rotation process. The elastic member 24 also has a buffering effect, reducing the wear on the action member 22 and increasing the service life of the action member 22. The elastic member 24 and the action member 22 are also convenient for assembly, disassembly and replacement.

[0038] In order to ensure the stability of the elastic sliding of the action member 22 on the strip groove 11, in one embodiment, the action member 22 includes a ball head 221 and a connecting rod 222, the ball head 221 abuts against the strip groove 11, and the connecting rod 222 is connected to the elastic member 24. The ball head 221 abuts against the strip groove 11, so that the contact point of the action member 22 with the strip groove 11 during the rotation process is more accurate, which is conducive to the user's perception of temperature changes more accurately. The connecting rod 222 is connected to the elastic member 24 to ensure the stability of the action member 22 and ensure that the action member 22 will not fall off following the rotation of the adjustment knob 21, thereby improving the reliability of the action member 22. The ball head 221 can also reduce the resistance when the adjustment knob 21 rotates. Specifically, the elastic member 24 adopts a spring, and the connecting rod 222 extends into the spring to provide support for the spring and ensure the stability of the spring.

[0039] In another embodiment, the action member 22 is a sphere, and one end of the elastic member 24 abuts against the surface of the sphere that is opposite to the strip groove 11. The action member 22 is a sphere, and the contact point with the strip groove 11 is more precise, which improves the perception of temperature adjustment changes. The sphere makes the impact sound more concentrated, which helps the user to more accurately judge the amplitude and direction of temperature adjustment. The contact area between the sphere and the strip groove 11 is small, thereby reducing friction, helping to reduce the wear of the action member 22 and the strip groove 11, extending the service life of the electric hot pot, and reducing production costs. The sphere can rotate when the adjustment knob 21 is rotated, converting sliding friction into rolling friction, and reducing the resistance when the adjustment knob 21 is rotated.

[0040] like Figure 6As shown, in order to ensure that the elastic member 24 is stably installed in the mounting blind hole 23, in one embodiment, the elastic member 24 is a conical coil spring, the end of the conical coil spring with a larger diameter is clamped in the mounting blind hole 23, and the end with a smaller diameter is abutted against the actuating member 22, the inner diameter of the mounting blind hole 23 is A, the diameter of the end with a larger diameter of the conical coil spring is B1, the diameter of the end with a smaller diameter is B2, the diameter of the front end of the actuating member 22 is C, B1>B2, B2≤C, B1≥A, to ensure that the elastic member 24 can be stably installed in the mounting blind hole 23, and the actuating member 22 can be driven to rotate with the adjusting knob 21 in a long-term and stable manner, to ensure that the actuating member 22 is stably connected to the conical coil spring, and to prevent the actuating member 22 from falling off during rotation.

[0041] In order to ensure the stability of the adjusting knob 21, in one embodiment, a receiving groove 12 is provided on the outer side of the pot body 1, the adjusting knob 21 is installed in the receiving groove 12, and the strip groove 11 is provided on the bottom surface of the receiving groove 12. The receiving groove 12 limits the adjusting knob 21, ensures the stability of the adjusting knob 21, fixes the adjusting knob 21 on the outside of the pot body 1, and also provides an installation guide for the adjusting knob 21, which is convenient for quick assembly. The strip groove 11 is provided on the bottom surface of the receiving groove 12 and cooperates with the adjusting knob 21 to produce a knocking sound to feedback the user's temperature adjustment range and direction.

[0042] like Figure 3 As shown, in one embodiment, the angle range a of the strip grooves 11 is 180°, which can provide a wider temperature adjustment range, allowing users to select different temperatures as needed. Users can judge the temperature and direction by the impact sounds at different positions, thereby controlling the temperature more accurately.

[0043] Among them, a sleeve 25 is provided at the bottom of the adjusting knob 21, which is nested with the rotating shaft 26 of the adjustable temperature controller 2. A buckle 27 is also provided at the bottom of the adjusting knob 21. The buckle 27 is snap-fitted with the pot body 1 to achieve the connection between the adjusting knob 21 and the adjustable thermostat 2 to control the working temperature of the heating tube. The buckle 27 surrounds the outer circumference of the sleeve 25 and is provided in plurality to ensure the stability of the adjusting knob 21 when it is rotated and will not fall off the pot body.

[0044] An indicator key 28 is also provided on the outer top of the adjustment knob 21. The indicator key 28 is opposite to the scale on the pot body 1. The indicator key 28 can be located on the back of the action part 22. The position indicated by the indicator key 28 is the position where the action part 22 is located. The user can know the current working temperature according to the temperature marked on the scale indicated by the indicator key 28.

[0045] In addition to achieving temperature adjustment by self-rotation, the adjusting knob can also achieve temperature adjustment by moving itself, such as reciprocating along an arc, similar to the movement of the adjusting knob based on the revolution of the electric hot pot, and the strip grooves 11 can be distributed according to the movement trajectory of the adjusting knob. In addition to the above preferred embodiments, the utility model has other implementation methods. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection requested by the utility model.
