Description

[0001] This application claims priority to Chinese Patent Application No. 2022114058318, filed on November 10, 2022, entitled "A Temperature Control Probe and a Stove Containing the Thereof", and incorporates the entire text thereof. Technical Field

[0002] This invention relates to the field of gas stove technology, specifically to a temperature control probe and a stove containing the same. Background Technology

[0003] Existing temperature-controlled anti-dry-burning gas stoves have temperature control probe structures as follows: Figure 1 As shown, point A is the bottom of the temperature control probe sleeve, point B is the top of the temperature control probe, point C is the sealing boss at the connection between the temperature control probe and the base mounting plane, and point D is the protruding ring at the mounting point of the temperature control probe's mounting sleeve and the stove burner. The total stroke L of the temperature control probe is the distance between point A and the base mounting plane (since the sealing boss is level with the base mounting plane, the total stroke L is the distance between points A and C). The total stroke L is the sum of the upper stroke L1 and the lower stroke L2. The part of the temperature control probe above the pot support plane is the upper stroke L1, and the lower stroke L2 = L - L1. The upper stroke L1 is the stroke above the pot support plane, and the lower stroke L2 is the stroke below the pot support plane. The design value of the upper stroke L1 determines the applicable range of flat-bottomed pans and casseroles (the bottom of a casserole is concave upwards), and the design value of the lower stroke L2 determines the applicable range of pointed pans (the bottom of a pointed pan is convex downwards). When the value of L1 is designed to be too large, since L is fixed, it will cause the value of L2 to become smaller, thus reducing the applicable range of the pointed pot and making it less adaptable. When the value of L1 is designed to be smaller and the value of L2 is increased, the applicable range of the pointed pot is increased, but because the value of L1 is too small, the probe cannot reach the bottom of the clay pot, making the clay pot unsuitable (losing functions such as dry burning protection).

[0004] In response to the above issues, the industry's general practice is as follows:

[0005] (1) Sacrificing the applicability of casserole to improve the applicability of pointed pot, that is, reducing the upper stroke L1 (without changing the probe structure and installation position, raising the pot support foot piece, which raises the pot support plane, thereby reducing L1). Since the total stroke L is constant, the upper stroke L1 is reduced, which makes the value of the lower stroke L2 larger. However, this approach will make the applicability of casserole particularly poor, most of them cannot be used and there are still a small number of ultra-pointed pots that are not suitable. The applicability of pointed pot has not been completely solved.

[0006] (2) Increase the total stroke L. Method 1: The burner structure remains unchanged (point C is not moved), the pot support feet are also not moved, and the temperature control probe is moved upward as a whole (points A and B are moved upward by ΔL). L1 becomes L1+ΔL, which improves the applicability of casserole. However, the value of L2 does not increase, meaning that the applicability of pointed pots still has problems and needs improvement. Method 2: The pot support feet are not moved, and the probe is moved upward by ΔL1 as a whole (points A and B are moved upward by ΔL1). At the same time, the position of the sealing boss C point is moved downward by ΔL2. The upper stroke becomes L1+ΔL1, the lower stroke becomes L2+ΔL2, and the total stroke becomes L+ΔL1+ΔL2. However, in this method, after the sealing boss C point is moved downward, C point is not level with the base plane, forming a pit. This pit is prone to liquid accumulation, affecting the probe performance. Some manufacturers will make the pit into a through hole, which extends into the stove base, making it easy for spilled food to escape. Residue falling into the base or cabinet is difficult to clean; Method 3: When point C is flush with the base plane without any pits, in order to improve the adaptability of the temperature control probe to both casserole and pointed pots, some burners are designed to increase the height of the burner head, thereby increasing the total stroke L by ΔL. The relative distance between A and B remains unchanged. Moving the installation position of point D upwards will raise point B, increasing the upper stroke L1, improving the adaptability to casserole, and increasing the total stroke L by ΔL, which means the lower stroke L2 can also be increased by ΔL. However, increasing the H value will make the burner head cavity volume larger, making the burner prone to popping. Also, if the burner head is too high, the height of the pot support will also increase accordingly (due to flue gas performance issues). The excessive height of the burner and pot support on the cooktop panel affects the aesthetic coordination of the entire cooktop. The user's cooking pots are placed at a higher height, affecting the user's cooking experience comfort.

[0007] The above methods all aim to increase the applicability of casseroles and pointed pots by changing the installation position of the temperature control probe or the structure of the burner. However, they do not actually improve the applicability of casseroles and pointed pots. In fact, changing the burner structure can also cause problems such as liquid accumulation, popping, and increased pot support, which affect performance and cooking experience. Therefore, they are not applicable in practice. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology in terms of the overall adaptability of cookware. By changing the structure of the temperature control probe without changing the burner structure, the applicability of both casserole and pointed pot can be improved.

[0009] The present invention solves the above-mentioned technical problems through the following technical solution:

[0010] A temperature control probe for use in a cooktop, the temperature control probe comprising:

[0011] Temperature sensing components;

[0012] Probe mounting components;

[0013] The elastic component includes a first elastic element and a second elastic element;

[0014] The sleeve assembly includes a first sleeve and a second sleeve, wherein,

[0015] The first elastic element is provided between the first sleeve and the second sleeve so that the first sleeve can move elastically vertically relative to the second sleeve;

[0016] A second elastic element is provided between the probe mounting assembly and the second sleeve so that the second sleeve can move elastically vertically relative to the probe mounting assembly;

[0017] The temperature measuring component is connected to the first sleeve and drives the first sleeve to move. During the downward movement of the first sleeve, the second sleeve is driven to move downward.

[0018] In this solution, the temperature control probe is improved from the existing single fixed sleeve to a sleeve assembly. The sleeve assembly is a telescopic sleeve structure formed by connecting the first sleeve and the second sleeve through a first elastic element. Since the overall length of the existing sleeve is fixed, when a pointed pot is used, the temperature measuring component moves vertically downward as the pointed pot is placed, which is the displacement generated at the bottom of the sleeve, i.e., the total stroke of the temperature control probe, which depends on the distance L between the bottom of the sleeve and the mounting plane of the base. However, in this solution, the overall length of the sleeve assembly can be compressed. Therefore, when a pointed pot is used, the temperature measuring component moves vertically downward as the pointed pot is placed. During this process, the sleeve assembly is compressed, and the overall length of the sleeve assembly decreases. The total stroke of the temperature control probe is the sum of the overall compressed length of the sleeve assembly and the displacement generated at the bottom of the sleeve. Therefore, the total stroke of the temperature control probe is greater than the displacement generated at the bottom of the sleeve assembly. That is, compared with the temperature control probe in the prior art, the upper stroke of the temperature control probe in this solution remains unchanged, the lower stroke increases with the compressed length of the sleeve assembly, and the total stroke also increases with the compressed length of the sleeve assembly.

[0019] This solution, by simply changing the structure of the temperature control probe itself, without altering the probe's size or installation position, can simultaneously expand the applicability of both casserole and pointed pot.

[0020] Since the structure of the stove burner has not been changed, the position of the sealing boss is still flush with the base mounting plane, so there will be no liquid accumulation pits or overflow holes at the sealing boss, and the burner is intact and easy to clean.

[0021] Preferably, the elastic coefficient of the first elastic element is smaller than that of the second elastic element. The first sleeve drives the second sleeve to move downward through the first elastic element. After the first sleeve moves downward to the position where it abuts against the second sleeve, it drives the second sleeve to move downward together.

[0022] In this scheme, during the downward movement of the first sleeve, the first elastic element and the second elastic element can be compressed simultaneously, and the compression of the first elastic element is greater than that of the second elastic element. Therefore, the movement process of the sleeve assembly is as follows: the first sleeve first abuts against the second sleeve, and the first sleeve drives the second sleeve to move down synchronously until the bottom of the second sleeve abuts against the base mounting plane.

[0023] Preferably, the elastic coefficient of the first elastic element is greater than or equal to the elastic coefficient of the second elastic element. The first sleeve drives the second sleeve to move downward through the first elastic element. After the second sleeve moves to the mounting plane of the base, the first sleeve continues to move downward until it abuts against the second sleeve.

[0024] In this scheme, during the downward movement of the first sleeve, the first elastic element and the second elastic element can be compressed simultaneously, and the compression of the first elastic element is less than that of the second elastic element. Therefore, the movement process of the sleeve assembly is as follows: the bottom of the second sleeve first abuts against the base mounting plane, the second sleeve remains stationary, and the first sleeve continues to move downward until the first sleeve abuts against the second sleeve.

[0025] Preferably, the inner wall of the sleeve assembly forms a cavity, and both the first elastic element and the second elastic element are disposed within the cavity.

[0026] In this solution, the first and second elastic elements can be kept out of the open.

[0027] Preferably, there is a gap between the sides of the first and second elastic elements and the inner sidewall of the sleeve assembly.

[0028] In this solution, the first and second elastic elements can be prevented from contacting the inner wall of the sleeve assembly, thereby reducing the heat transfer from the sleeve assembly to the first and second elastic elements and thus affecting the accuracy of the temperature measuring assembly.

[0029] Preferably, the diameter of the first sleeve is smaller than the diameter of the second sleeve, one end of the first sleeve is located inside the second sleeve, and the end of the first sleeve located inside the second sleeve is fixed with an upper sliding ring protruding from the outer surface of the first sleeve, the outer side wall of the upper sliding ring being slidably connected to the inner side wall of the second sleeve.

[0030] In this scheme, the sliding connection between the first sleeve and the second sleeve is achieved by sliding the first sleeve inside the second sleeve.

[0031] Preferably, a horizontally arranged top plate is fixed to one end of the second sleeve surrounding the first sleeve. The top plate has a top plate through hole, and the first sleeve is located in the top plate through hole. The top plate can abut against the upper sliding ring to limit the position of the upper sliding ring in the vertical direction.

[0032] In this design, when the temperature measuring component moves downward, it can abut against the upper sliding ring through the top plate, thereby preventing the second sleeve from sliding out of the first sleeve and ensuring that the second sleeve always slides inside the first sleeve.

[0033] Preferably, a support is provided in the inner cavity of the second sleeve, one end of the first elastic element is connected to the upper surface of the support and the other end is connected to the temperature measuring component, one end of the second elastic element is connected to the lower surface of the support and the other end is connected to the probe mounting component.

[0034] In this design, the support facilitates the installation of the first elastic element and the second elastic element.

[0035] Preferably, both the first elastic element and the second elastic element are springs.

[0036] In this design, the spring structure is simple and can achieve an effective elastic connection.

[0037] Preferably, the temperature measuring component includes a heat collection plate and a temperature sensor. The heat collection plate is horizontally arranged for contacting the object to be measured above the temperature measuring component. The temperature sensor is disposed inside the heat collection plate and is also connected to a lead wire. The lead wire passes through the sleeve assembly and the probe mounting assembly and extends downward to output the electrical signal generated corresponding to the temperature change. The inner sidewall of the sleeve assembly forms a cavity, and the lead wire passes through the cavity. One end of the sleeve assembly is fixed to the lower surface of the heat collection plate.

[0038] In this scheme, the heat collection plate is used to contact the bottom of the pot and conduct heat to the temperature sensor, and then outputs the corresponding electrical signal generated by the temperature change through the lead wire.

[0039] Preferably, the probe mounting assembly includes a mounting sleeve, and the lead wire passes through the mounting sleeve and extends downward.

[0040] In this solution, the installation of the sleeve facilitates the installation of the entire temperature control probe inside the stove and also makes it easy to lead out the lead wire.

[0041] The present invention also provides a cooktop, including the temperature control probe described above.

[0042] The positive and progressive effects of this invention are as follows:

[0043] In this invention, the sleeve assembly is formed by connecting a first sleeve and a second sleeve through a first elastic element. When using a pointed pot, the temperature measuring component moves vertically downward as the pointed pot is placed. During this process, the sleeve assembly is compressed, and the overall length of the sleeve assembly decreases. Therefore, compared with the temperature control probe in the prior art, the upper stroke of the temperature control probe of this invention remains unchanged, but the lower stroke increases the length of the compressed sleeve assembly, and the total stroke also increases the length of the compressed sleeve assembly. This invention can improve the applicability of both casserole and pointed pots by simply changing the structure of the temperature control probe itself, without changing the size and installation position of the temperature control probe itself.

[0067] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0068] like Figure 2-4 As shown, this embodiment provides a temperature control probe 100 for use in stoves. Figure 2-3 A schematic diagram of the installation structure of the temperature control probe 100 relative to the stove is shown. The structure of the temperature control probe 100 is as follows: Figure 4 As shown, it includes: a temperature measuring component, a sleeve component, and a probe mounting component.

[0069] The temperature measuring component is positioned above the stove and can move vertically downwards as the object to be measured is placed on top of it. Specifically, the object to be measured above the temperature measuring component is a pot, which can be a clay pot, a flat-bottomed pan, or a pointed pan. The bottom of the pot presses down on the upper surface of the temperature measuring component, thereby pressing the temperature measuring component to move vertically downwards.

[0070] The temperature measuring component includes a heat collection plate 111 and a temperature sensor 112. The heat collection plate 111 is horizontally arranged and made of thermally conductive material. It is used to contact the bottom of the pot and conduct heat to the temperature sensor 112. The temperature sensor 112 is located inside the heat collection plate 111 and is a high-temperature resistant sensor. The temperature sensor 112 is also connected to a lead wire 113. The lead wire 113 passes through the sleeve assembly and the probe mounting assembly and extends downward to output the electrical signal generated by the temperature change.

[0071] The probe mounting assembly includes a mounting sleeve 160, with a lead wire 113 inserted into the mounting sleeve 160 and extending downward. The mounting sleeve 160 is used to fix the probe 100 inside the burner of the stove, thereby achieving the installation and fixation of the temperature control probe 100 inside the stove.

[0072] The sleeve assembly includes a first sleeve 120 and a second sleeve 130. A first elastic element 140 is disposed between the first sleeve 120 and the second sleeve 130 so that the first sleeve 120 can move elastically in the vertical direction relative to the second sleeve 130. A second elastic element 150 is disposed between the probe mounting assembly and the second sleeve 130 so that the second sleeve 130 can move elastically in the vertical direction relative to the probe mounting assembly.

[0073] Specifically, both the first sleeve 120 and the second sleeve 130 are cylindrical, with the diameter of the first sleeve 120 being smaller than that of the second sleeve 130. Both ends of the first sleeve 120 and the second sleeve 130 are open, and the inner wall of the first sleeve 120 forms a cavity. One end of the first sleeve 120 is welded and fixed to the heat collection plate 111, and the other end is located inside the second sleeve 130. An upper sliding ring 121 protruding from the outer surface of the first sleeve 120 is fixed to the end of the first sleeve 120 located inside the second sleeve 130. The outer wall of the upper sliding ring 121 is slidably connected to the inner wall of the second sleeve 130 to achieve a vertical sliding connection between the first sleeve 120 and the second sleeve 130. A horizontally arranged top plate 134 is welded and fixed to one end of the second sleeve 130 surrounding the first sleeve 120. The top plate 134 has a top plate through hole, and the first sleeve 120 is located in the top plate through hole. The top plate 134 can vertically abut against the upper sliding ring 121 to limit the position of the upper sliding ring 121 in the vertical direction. The edge of the heat collecting plate 111 protrudes from the side wall of the first sleeve 120. When the bottom of the pot presses the heat collecting plate 111 to move vertically downward, after the bottom edge of the heat collecting plate 111 abuts against the top of the top plate 134, the heat collecting plate 111 can continue to press the first sleeve 120 to move downward synchronously.

[0074] A horizontally positioned support 132 is fixed in the middle of the second sleeve 130. A through hole is provided in the middle of the support 132 for the lead wire 113 to pass through. The second sleeve 130 also contains an inner cylinder 131. The top of the inner cylinder 131 is fixed to the lower surface of the support 132. One end of the mounting sleeve 160 is located within the inner cylinder 131, and a lower sliding ring 133 is fixed to the end of the mounting sleeve 160 located within the inner cylinder 131. The lower sliding ring 133 is vertically slidably connected to the inner wall of the inner cylinder 131. The inner wall of the inner cylinder 131 forms a cavity, in which the second elastic element 150 is disposed.

[0075] The first elastic element 140 and the second elastic element 150 can be various conventional springs, such as straight springs or conical springs. Both the first elastic element 140 and the second elastic element 150 are sleeved on the outside of the lead wire 113. One end of the first elastic element 140 is fixed to the lower surface of the heat collection plate 111, and the other end is fixed to the upper surface of the support 132, providing a vertical elastic force to the first sleeve 120. One end of the second elastic element 150 is fixed to the lower surface of the support 132, and the other end is fixed to the end of the mounting sleeve 160, providing a vertical elastic force to the second sleeve 130.

[0076] In this invention, when the cookware is placed on the temperature measuring component, the weight of the cookware is transmitted to the mounting sleeve 160 through the first elastic element 140 and the second elastic element 150, causing both the first elastic element 140 and the second elastic element 150 to be compressed. The first elastic element 140 and the second elastic element 150 form a series spring. Therefore, the total stroke L of the temperature measuring component pressed down by the cookware, i.e., the temperature control probe 100, is the sum of the compression amount l1 of the first elastic element 140 and the compression amount l2 of the second elastic element 150 (L = l1 + l2). The upper stroke L1 is the distance from the top of the temperature measuring component to the plane of the cookware support 300, and the lower stroke L2 = l1 + l2 - L1. l1 is the compression amount of the sleeve assembly, and l2 is the distance from the bottom of the second sleeve 130 to the base mounting plane 400.

[0077] The movement of the sleeve assembly can be divided into the following different cases (assuming the elastic coefficient of the first elastic element 140 is k1 and the elastic coefficient of the second elastic element 150 is k2):

[0078] When k1 is less than k2, after the pot is placed on the temperature measuring component, the temperature measuring component moves downward, causing the first sleeve 120 to move downward synchronously. When the first sleeve 120 moves downward, the first sleeve 120 drives the second sleeve 130 to move downward through the first elastic element 140. During this process, both the first elastic element 140 and the second elastic element 150 are compressed until the first sleeve 120 and the second sleeve 130 abut against each other. Then, the first sleeve 120 drives the second sleeve 130 to move downward synchronously (during this process, the first elastic element 140 is no longer compressed, only the second elastic element 150 is compressed) until the bottom end of the inner cylinder 131 of the second sleeve 130 abuts against the base mounting plane 400.

[0079] Specifically, when k1 is much smaller than k2, after the cookware is placed on the temperature measuring component, during the compression of the first elastic element 140, the compression of the second elastic element 150 is almost negligible. Therefore, during the descent of the first sleeve 120, the second sleeve 130 remains almost stationary until the first sleeve 120 moves down to abut against the second sleeve 130. Then, the first sleeve 120 drives the second sleeve 130 to move down synchronously until the bottom of the inner cylinder 131 of the second sleeve 130 abuts against the base mounting plane 400.

[0080] When k1 is greater than or equal to k2, after the pot is placed on the temperature measuring component, the temperature measuring component moves downward, causing the first sleeve 120 to move downward synchronously. When the first sleeve 120 moves downward, the first sleeve 120 drives the second sleeve 130 to move downward through the first elastic element 140. During this process, both the first elastic element 140 and the second elastic element 150 are compressed until the bottom end of the inner cylinder 131 of the second sleeve 130 first abuts against the base mounting plane 400. The second sleeve 130 remains stationary, and the pot drives the temperature measuring component to continue moving downward. With the second sleeve 130 remaining stationary, the first sleeve 120 can continue to move downward until the first sleeve 120 abuts against the second sleeve 130.

[0081] Specifically, when k1 is much greater than k2, after the pot is placed on the temperature measuring component, the temperature measuring component moves downward, causing the first sleeve 120 to move downward synchronously. During this process, the second elastic element 150 is compressed, and the compression of the first elastic element 140 is almost negligible. Therefore, during this process, the temperature measuring component moves downward, causing the first sleeve 120 and the second sleeve 130 to move downward synchronously until the bottom end of the inner cylinder 131 of the second sleeve 130 abuts against the base mounting plane 400. The second sleeve 130 remains stationary, and the pot drives the temperature measuring component to continue moving downward. With the second sleeve 130 remaining stationary, the first sleeve 120 can continue to move downward until the first sleeve 120 abuts against the second sleeve 130.

[0082] Regardless of the relationship between k1 and k2, as long as the first elastic element 140 can be compressed, the overall length of the sleeve assembly is compressed. Compared to the traditional temperature control probe 100 with a fixed-length sleeve, the temperature control probe 100 of this invention increases the compressed length of the sleeve assembly in both its lower stroke and total stroke. This invention, by simply changing the structure of the temperature control probe 100 itself, without altering its size or installation position, can simultaneously expand the applicability of both casserole dishes and pointed pots.

[0083] This embodiment also provides a stove, which includes the aforementioned temperature control probe 100.
