Abstract
Description
Technical Field
[0001] A temperature indicator is provided for use with cookware, such as cookware used on a cooktop. Background Art
[0002] Pots and pans are common forms of cookware used by people around the world. Such cookware is typically constructed of metal and includes a body with a flat bottom and sidewalls to hold food during cooking activities. In some cases, the cookware also includes one or more handles for easier gripping, thereby reducing the risk of burns.
[0003] During cooking, cookware is typically placed on a cooktop to receive the heat used for cooking. The cooktop includes burners on which the cookware rests. The burners generate heat, which is then absorbed by the cookware and transferred to the items being cooked within the cookware. Many recipes require the cooktop or burners to be set to a specific heat range, such as medium, high, or low. For similar burner settings, different cookware and burner combinations can produce a wide range of cooking temperatures. For example, a small gas burner set to 50% can produce a different cooking temperature with a single pot than an induction cooktop set to 50% with the same pot. Similarly, a gas burner will produce different cooking temperatures with pots of different sizes. Traditionally, the appropriate cooking temperature is adjusted to the burner settings through trial, error, and experience.
[0004] Therefore, there remains a need for improved methods and apparatus for controlling the temperature of a cooker. Summary of the Invention
[0005] The present disclosure relates to the need to display the temperature of a cooking surface on a cookware handle.
[0006] In one embodiment, a cooking pot is provided, comprising a pot body having a cooking surface and a heating surface opposite the cooking surface. A handle may be attached to the pot body. A hole may extend into the pot body substantially parallel to the cooking surface and the heating surface, and a thermal probe may extend at least partially into the hole. The thermal probe may be configured to detect the temperature of the pot body. The cooking pot may further comprise a thermal gauge mounted on and held by the handle. The thermal gauge and the handle define corresponding profiles that hold the gauge to the handle once the gauge is rotated against the handle. The gauge is also coupled to the thermal probe. The thermal gauge may be configured to indicate a temperature in response to the temperature detected by the thermal probe.
[0007] The pot body can have various configurations. In one embodiment, the pot body can include a first aluminum layer closer to the cooking surface than the heating surface, an induction layer closer to the heating surface than the cooking surface, and a second aluminum layer between the first aluminum layer and the induction layer. In some embodiments, the induction layer can include martensitic stainless steel.
[0008] The hole may be formed at various locations, but in one embodiment, the hole may be defined as passing through the second aluminum layer. In certain embodiments, the hole may have a diameter that is substantially 0.2 mm larger than the diameter of the heat measuring instrument when the pot body is at room temperature.
[0009] In another embodiment, the corresponding contour may include a shoulder that interlocks with a corresponding shoulder on the thermal measurement instrument to retain the thermal measurement instrument on the handle. The handle may include a first grip portion and a second portion having a handle aperture. In some embodiments, the first grip portion and the second portion extend transversely relative to each other.
[0010] In one embodiment, a cooking pot may include a pot body having a cooking surface and a heating surface opposite the cooking surface. A handle may be coupled to the pot body. A probe may extend into the pot body and be configured to detect the temperature of the pot body. In some embodiments, a thermal measurement instrument may be mounted in the pot body handle and coupled to the probe. The thermal measurement instrument may be configured to indicate a temperature in response to the temperature detected by the thermal probe.
[0011] In some embodiments, the probe can be bent so that a first portion of the probe coupled to the thermal measuring instrument extends transversely to a second portion of the probe extending into the pot body. In some embodiments, the handle includes an opening in which the thermal measuring instrument can be positioned. In some embodiments, the thermal measuring instrument can be freely moved relative to the handle along a central axis of the opening. Alternatively or additionally, the opening in the handle includes a shoulder that interlocks with a corresponding shoulder on the thermal measuring instrument to retain the thermal measuring instrument in the opening in the handle. In such an embodiment, the shoulder on the thermal measuring instrument can be configured to interlock with the shoulder in the opening in the handle by inserting the shoulder on the thermal measuring instrument through the opening in the handle and rotating the thermal measuring instrument.
[0012] In one embodiment, a cooking pot includes a pot body having a cooking surface and a heating surface opposite the cooking surface. A handle may be coupled to the pot body. A thermal probe may extend between the pot body and the handle. A shield may surround at least a portion of the thermal probe. The shield may be configured to shield the thermal probe from radiant heat.
[0013] In some embodiments, the thermal probe includes a curved portion. The guard may be in the form of a boot having an upper portion and a lower portion extending at an angle relative to each other to extend over the curved portion of the thermal probe. The upper portion of the guard may include opposing lateral sides, while in some embodiments, the lower portion of the guard may include an elongated extension extending into the pot body.
[0014] In some embodiments, the pot body includes a recess configured to receive a portion of the elongated extension of the guard. In some embodiments, the pot body may define a hole. The thermal probe may then be at least partially retained within the hole.
[0015] In some embodiments, the guard comprises a single, integral piece. In some embodiments, the guard can be attached to a handle. The handle can include an elongated gripping portion and an attachment portion attached to a sidewall of the pot body. The guard can extend along the sidewall of the pot body from a lower surface of the attachment portion to the heated surface of the pot body. In some embodiments, a temperature measuring instrument can be mounted in the handle and coupled to the thermal probe. The temperature measuring instrument can be configured to indicate the temperature of the pot body as detected by the thermal body.
[0016] In one embodiment, a cooking pot includes a pot body having a base portion with an upper cooking surface and a lower heating surface. Sidewalls may extend upward from the base portion. A handle may include an attachment portion coupled to the sidewall of the pot body and an elongated gripping portion extending outward from the attachment portion. A guard may extend along the sidewall of the pot body and between a lower surface of the handle attachment portion and the lower heating surface of the pot body.
[0017] In some embodiments, a thermal measurement meter may be mounted to the handle. A thermal probe may extend from the thermal measurement meter and into the pot body between the cooking surface and the heating surface. The thermal measurement meter may be configured to indicate the temperature of the pot body detected by the thermal probe.
[0018] In some embodiments, a guard can be positioned around a portion of the heat probe extending from the handle attachment portion to the cooking surface to shield the heat probe from radiant heat. A portion of the guard can extend into the base portion of the pot body. The guard can include an elongated extension and opposing lateral sidewalls extending upward from the elongated extension, which can define a hollow cavity between the lateral sidewalls.

[0057] Certain embodiments will now be described to provide a comprehensive understanding of the principles of structure, function, manufacture, and use of the devices and methods disclosed herein. One or more examples of these embodiments are shown in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and shown in the accompanying drawings are non-limiting embodiments, and that the scope of the present invention is limited solely by the claims. Features described or illustrated in conjunction with one embodiment may be combined with features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.
[0058] Furthermore, in this disclosure, similarly named components of an embodiment generally have similar features, and thus, in a particular embodiment, it is not necessary to fully and exhaustively set forth every feature of every similarly named component. Additionally, to the extent that linear or circular dimensions are used in the descriptions of the disclosed systems, apparatus, and methods, such dimensions are not intended to limit the types of shapes that may be used in conjunction with such systems, apparatus, and methods. One skilled in the art will recognize that equivalents to such linear and circular dimensions may be readily determined for any geometric shape. The size and shape of the systems and apparatus and their components may depend at least on the composition of the object in which the systems and apparatus will be used, the size and shape of the components with which the systems and apparatus will be used, and the methods and procedures in which the systems and apparatus will be used.
[0059] A temperature sensing assembly for use with various types of cookware, such as pots, is provided. The temperature sensing assembly is configured to read the temperature at the base of the cookware and display the temperature on a gauge mounted on or adjacent to the cookware handle. This allows the user to easily view and monitor the temperature during cooking. Also provided are methods and apparatus for easily mounting the temperature sensing assembly on the cookware while still accounting for any deformation of the handle relative to the cookware due to heat and / or flexing. Furthermore, a guard is provided to protect the temperature sensing assembly from thermal damage during use.
[0060] Figure 1A and Figure 1B One embodiment of a cookware assembly 200 is shown, comprising a pot 100 having a handle 204 and a temperature sensing assembly 300 coupled to the handle 204. Specifically, as shown, the temperature sensing assembly 300 includes a gauge 304 mounted in the handle 204 to indicate the temperature of the pot. A probe (not shown) extends from the gauge 304 into the base of the pot, as will be discussed in further detail below, for measuring the temperature indicated by the gauge. As further shown, a shield 600 is disposed around a portion of the temperature sensing assembly to protect the temperature sensing assembly from shock and / or heat.
[0061] The pot body 100 can have various configurations, and although a pot is shown, those skilled in the art will appreciate that the temperature sensing assembly disclosed herein can be mounted to any type of cookware, including various pots, pans, grills, baking trays, ovens, etc. In the illustrated embodiment, as shown Figure 2As shown in more detail in FIG, the pot body has a base portion 102 having an upper cooking surface 104 and a lower heating surface 106. Sidewalls 107 extend upward from the base portion 102 for holding food within the pot 100. The cooking surface 104 is configured to receive food for heating, and the heating surface 106 is configured to rest on a cooktop (such as a gas burner, a conductive electric burner, or an induction burner). The pot body 100 may include several layers of different materials. In the illustrated embodiment, the upper cooking surface 104 is formed of a material that is safe for food contact at high heat (such as stainless steel, an aluminum alloy, cured cast iron, ceramic, and / or a non-stick coating), and the lower heating surface 106 is formed of a material with sufficient strength and heat transfer capabilities (e.g., stainless steel, an aluminum alloy, cured cast iron, ceramic, and / or a durable coating). The pot body 100 includes a first aluminum or aluminum alloy layer 108 adjacent to the cooking surface 104, and an induction layer 110 adjacent to the heating surface 106 or defining a portion of the heating surface 106. The induction layer allows the pot body to interact with (e.g., be heated by) an induction cooktop. The induction layer can be made of a magnetic material such as martensitic stainless steel. Alternatively or additionally, the induction layer can include an iron-containing material such as cast iron. In some embodiments, an induction coating can be used without departing from the present disclosure. In some embodiments, a second aluminum or aluminum alloy layer 112 can be included between the first aluminum layer 108 and the induction layer 110. The described layers can be manufactured and combined in various ways, such as by press-fitting the layers into a single piece.
[0062] Regardless of the layering, the individual layers comprise the base 102 of the pot body 100. The base 102 transfers heat from the heating surface 106 to the cooking surface 104. In some embodiments, the base 102 is configured to distribute heat more evenly across the cooking surface 104 than a single-layer pot body.
[0063] As described above, the temperature sensing assembly is configured to measure the temperature of the pot body. Accordingly, the pot body 100 may define a blind hole 114 extending therein, which is configured to receive a portion of a probe on the temperature sensing assembly, as will be discussed below. The hole 114 may be formed at various locations, but is preferably located at a location such as Figure 2 In the illustrated embodiment, the holes 114 extend substantially parallel to the cooking surface 104 and the heating surface 106. The holes 114 preferably do not penetrate the cooking surface 104 or the heating surface 106. In some embodiments, the holes can be formed through and / or defined by the second aluminum layer 112. Such holes 114 can be created in various ways. For example, the holes 114 can be formed in a single drilling pass using a pilot drill bit. In other embodiments, the holes 114 can be pre-formed in the second aluminum layer 112 prior to assembly with the other layers.
[0064] As mentioned above, the pot body may also include a handle 204 for easy gripping. Figure 3 As shown in more detail in FIG, in one embodiment, the handle 204 can have a generally elongated configuration with an attachment portion 202 configured to couple or attach to the sidewall 107 of the pot body 100 and an elongated gripping portion 204a extending outwardly from the attachment portion 202. While various techniques can be used to mate the attachment portion 202 to the pot body, in one embodiment as shown, the attachment portion 202 can include one or more holes 206 therein. The holes 206 can be aligned with corresponding holes in the sidewall 107, thereby allowing the handle 204 to be attached to the pot body 100 using fasteners (such as rivets 207, screws, etc.). Other fastening techniques can be used without departing from the present disclosure.
[0065] like Figure 3 As further shown, the attachment portion may include an opening 201 suitable for accommodating a measuring instrument of the temperature sensing assembly. The configuration of the opening 201 may vary depending on the configuration of the temperature measuring instrument. In the embodiment shown, the opening is generally semicircular. As will be explained in more detail below, the opening may include features that facilitate the placement of the measuring instrument 304.
[0066] Figure 4A The temperature sensing assembly 300 including a thermal probe 302 and a measuring meter 304 is shown in greater detail. While the probe 302 can have a variety of shapes and sizes, it is preferably shaped to extend from the measuring meter to the bottom of the pot. Accordingly, in one embodiment, the probe 302 can be bent such that a first substantially linear portion 302a and a second substantially linear portion 302b of the probe 302 extend at an angle relative to each other with a bend 305 therebetween. The angle can vary depending on the configuration of the pot and the handle. The thermal measuring meter 304 can be formed on or mated to one end of the first portion 302a and can include features that indicate the temperature of the pot. In the embodiment shown, the measuring meter 304 includes a dial 308 having graduated markings (not shown) corresponding to the temperature sensed by the thermal probe 302. In some embodiments, the dial can be marked to indicate a temperature range, such as low heat, medium heat, and high heat, as shown. Figure 1B The dial can also be marked with temperature ranges that are considered too hot or too cold for the pan. For example, if the pan is nonstick, the nonstick coating works best within a specified temperature range. At temperatures that are too low, the nonstick coating may not function properly. At temperatures that are too high, the nonstick coating may degrade. Having a dial with these temperature ranges allows users to keep the pan within the ideal temperature range and prolongs the pan's life.
[0067] In certain embodiments, a bimetallic strip may be used to control the meter 304 . Figure 4BOne embodiment of a temperature sensing assembly 350 is shown, including a thermal probe 352 having a coiled or wound bimetallic strip 360 coupled to an indicator needle 359 on a measuring instrument 354. Specifically, the coiled or wound bimetallic strip 360 is positioned within the interior of the probe 352, with one end attached near the front end 353. This attachment can be achieved by welding, brazing, adhesive bonding, mechanical bonding, or other attachment means. A wire 355 can connect the coiled or wound bimetallic strip 360 to a tension spring 357 extending between the wire and the temperature measuring instrument 354. Each end of the tension spring 357 can include a coupling portion 357a for connecting the tension spring 357 to the wire. The coupling portions can be achieved by welding, brazing, adhesive bonding, mechanical bonding, or other attachment means. In this embodiment, differences in thermal expansion can cause the bimetallic strip to rotate, which in turn causes the tension spring to rotate, resulting in movement of the indicator needle. In another embodiment (not shown), the bimetallic coil can continue along the entire length of the probe and can be directly coupled to the temperature measuring instrument so that the rotation of the single coil moves the dial. Although primarily described with bimetallic strip 360, other temperature sensing and display systems can be used without departing from the present disclosure. For example, a scale indicator or thermocouple with an expandable fluid can be used. Although shown and described as a separate embodiment, in some cases, temperature sensing assembly 350 can be used in place of temperature sensing assembly 300 without departing from the present disclosure.
[0068] The temperature sensing assembly 300 may be mounted to the pot using various techniques. In one embodiment, Figure 5As shown, a measuring instrument 304 can be mounted in the opening 201 in the handle 204, and a heat probe 302 can extend from the handle into the pot body 100 and at least partially into the aperture 114. The heat probe 302 preferably extends into the pot body 100 a distance that effectively measures a representative temperature of the cooking surface 104. For example, it can extend to a position substantially three inches from the center of the pot body 100 or substantially 55 millimeters (mm) from the edge of the pot body 100 (within standard manufacturing tolerances). This distance can vary depending on the size of the pot body 100. Typically, the front end of the heat probe 302 can be located approximately one-third of the pot bottom diameter from the center of the pot. Because different burner types distribute heat differently, this distance is sufficiently representative of the cooking surface temperature on various burner types (e.g., conductive, inductive, or gas burners). The aperture 114 can be sized to receive and at least partially retain the heat probe 302 in both depth and diameter. For example, the aperture 114 can be slightly deeper than the length of the probe 302 that penetrates into the pot body 100. The diameter of the hole 114 can be slightly larger than the diameter of the thermal probe 302, for example, substantially 0.2 millimeters (mm) larger (within standard manufacturing tolerances at room temperature). During use, after exposure to heat, thermal expansion can reduce the size of the hole 114 so that it creates a friction-tight fit around the probe 302. Figure 2 ) Improved thermal coupling with direct contact, which can improve temperature reading accuracy.
[0069] In order to mount the thermal measurement meter 304 to the handle 204, as described above, the handle 204 can define a handle opening 201. In one embodiment, as shown, the handle opening 201 can include a support structure 401 that is at least partially positioned in the handle opening and has an upper surface configured to house the measurement meter 304. The support structure 401 can include a hole 402 extending therethrough for receiving a probe. In some embodiments, the measurement meter 304 and the support structure 401 can include corresponding profiles that retain the measurement meter 304 to the handle 204 once the measurement meter is rotated into place. For example, in some embodiments, a shoulder 404 can be formed around the hole 402 adjacent to the lower surface of the support structure 401. The shoulder 404 can be configured to interlock with a corresponding shoulder 406 on the thermal measurement meter 304 to retain the thermal measurement meter 304 to the handle. The interlocking shoulders 404, 406 Figures 6A to 6C As shown in more detail in Figure 6AAs shown, the shoulder 406 on the temperature sensing assembly 300 is positioned directly below the measuring instrument 304 at the tip of the probe. The shoulder 406 is in the form of a radially extending flange having an elliptical configuration with two curved ends connecting two opposite straight sides, wherein the straight sides are longer in length than the curved ends. Figure 6B As shown, the shoulder 404 on the handle includes an oval opening having a complementary shape that is configured to receive the shoulder 406 on the meter. Once the shoulder 406 on the meter passes through the handle aperture 402 from the upper surface to the lower surface, the temperature sensing assembly can be rotated approximately 90 degrees so that the shoulder 406 extends downward and engages the shoulder 404 on the handle. In other words, the shoulder 406 on the meter is rotated out of alignment with the shoulder on the handle to prevent the meter from being removed from the handle, as shown. Figure 6C As shown. Once the gauge 304 and thermal probe 302 are attached to the handle, the probe can be inserted into the pot body 100 and the handle can be installed to the pot body to fully assemble the device. Those skilled in the art will understand that other keying features or other techniques can be used to mate the gauge to the shoulder. That is, other keying or rotatable coupling features can be used without departing from the present disclosure, for example, a threaded connection, a snap connection, or other bayonet-type connection can be used.
[0070] In other embodiments, 7A to 7C As shown, the gauge is free to float relative to the handle. Except for any differences described herein, 7A to 7C The illustrated handle and meter interface are substantially similar to the previously described embodiments. As shown, the handle 500 includes a handle opening 502 having a diameter slightly larger than the meter 304. In this embodiment, the opening is cylindrical so that it completely accommodates the meter. The opening does not include any mating features for engaging the meter. Therefore, the meter is able to move freely along the central axis 504 of the handle opening 502. That is, any flexion between the handle 500 and the pot body 100 is reduced or minimized from being transferred to the meter 304, so that the handle 500 and the meter 304 can move freely relative to each other along the central axis 504 of the handle opening 502. In this embodiment, the meter 304 is supported by coupling the thermal probe 302 to the pot body. During assembly, this can be achieved by inserting the thermal probe 302 through the handle opening 502 and into the hole 114 in the pot body, and then mounting the handle to the pot body 100.
[0071] The cookware assembly disclosed herein may further include a guard for protecting the temperature sensing assembly. Figure 8AFIG1 shows the guard 600 in greater detail. As will be appreciated, a portion of the thermal probe 302 extending from the pot body to the thermal measurement instrument 304 is exposed and potentially damaged by excessive radiant heat and / or impact. To mitigate this, the guard 600 can be configured to surround at least a portion of the thermal probe, thereby shielding it from radiant heat and potential impact. While the guard 600 can have various shapes and sizes, in the illustrated embodiment, the guard 600 takes the form of a hollow boot, wherein an elongated base or extension 602 has opposing lateral sidewalls 604 extending upward from the elongated extension to define a hollow cavity therebetween. When the guard is mounted on the pot, the hollow cavity can accommodate the curved portion 305 of the thermal probe 302. In other words, the guard 600 takes the form of a boot, having an upper portion 606 and a lower portion 608 that extend at an angle relative to each other to extend over at least the curved portion 305 of the thermal probe 302.
[0072] The guard 600 can be constructed in various ways. For example, in some embodiments, the guard can be press-formed into a single integral piece. In some embodiments, the guard 600 is composed of multiple pieces that are welded, brazed, or otherwise fastened together.
[0073] When fully assembled to the pot, as Figure 8B As shown, the guard 600 can be positioned along the side wall 107 of the pot body 100 so that it extends between the lower surface of the attachment portion 202 of the handle and the lower heating surface 106 of the pot body 100. This configuration positions the guard 600 around the curved portion 305 of the thermal probe 302 extending from the attachment portion 202 of the handle 204 to the base 102 to protect the thermal probe 302 from radiant heat or shock. In some embodiments, the guard 600 can be welded, brazed, adhered, or otherwise attached to the side wall to prevent and / or reduce the ingress of fluid between the guard 600 and the side wall 107.
[0074] In some embodiments, the guard 600 can be attached to the handle 204. Various mating features can be used, such as tabs 610 formed on the guard. The tabs 610 can be configured to extend into corresponding slots (not shown) formed in the handle 204 or the pot body. Alternatively or additionally, the handle 204 can press the tabs 610 against the sidewalls 107 of the pot body to hold the guard to the handle 204. In other embodiments, the guard 600 can be attached only to the handle 204, allowing the guard 600 to flex in unison with the handle relative to the pot body 100 during active use.
[0075] In other embodiments, Figures 9A to 9BAs shown, a portion of the guard 600a can extend into the base portion of the pot body 100a. In this embodiment, the pot body 100a can include one or more recesses 902 defined by the pot body 100a and configured to receive a portion of the elongated extension 602a of the guard 600a, such as a tab 907. This embodiment can couple the guard to both the pot body 100 and the handle 204. This coupling can increase the rigidity of the handle relative to the pot body 100.
[0076] In other embodiments, 10A to 10F As shown, the thermal probe 302 may include a bracket 804. The bracket 804 shown includes a through hole 805 configured on a first end of the bracket 804 and a through hole 806 configured on a second end of the bracket 804 opposite the through hole 805. The through hole 805 is formed into a shape corresponding to the outer diameter of the thermal probe 802. The thermal probe 302 can be threaded through the through hole 805 to position a portion of the curved portion 305 within the bracket 804. The through hole 806 can be configured to receive a screw 808 or other attachment feature to facilitate mating of the protective member with the bracket 804. In one embodiment, the through hole 806 can be a threaded hole.
[0077] As further shown, a guard 810 is configured to cover the bracket 804 and the thermal probe 302 to protect the thermal probe 302. The guard 810 can be substantially similar to the guard 600, and therefore similar components will not be described in detail. The illustrated guard 810 includes a hole 812 disposed on an upper portion 814 of the guard 810 and configured to receive a screw 808. When the guard 810 is disposed on the bracket 804, the through hole 806 and the hole 812 are aligned. This alignment allows the screw 808 to pass through the hole 812 and into the through hole 806. When the screw 808 is disposed in both the through hole 806 and the hole 812, the guard 810 is secured to the thermal probe 302 via the bracket 804.
[0078] In other embodiments, Figures 11A to 11B As shown, the thermal probe 302 can be secured relative to the guard using a spring member 904. The thermal probe 302 is retained within the guard 900 by the spring member 904 to support the thermal probe 302. The guard 900 is substantially similar to the guard 600, and therefore similar components will not be described in detail. The guard 900 shown includes a first notch 906 and a second notch 908 disposed in opposing lateral sidewalls 910. The notches 906, 908 are aligned with one another along the lateral sidewalls 910 and are configured such that gaps 912, 914 are formed in the lateral sidewalls 910.
[0079] The spring member 904 is disposed within the guard 900 and includes a curved section 911 and tabs 916, 918 disposed on opposite sides of the curved section 911. The tabs 916, 918 are shaped to match the shapes of the recesses 906, 908, respectively. Gaps 912, 914 are configured to receive the tabs 916, 918 of the spring member 904 to retain the thermal probe 302 in place within the guard 900. In another embodiment, the spring member 904 can be welded within the guard 900. The curved section 911 can be shaped to correspond to the outer diameter of the thermal probe 302. The spring member 904 can push the thermal probe 302 downward, thereby securing the thermal probe relative to the guard 900.
[0080] In other embodiments, FIG. 12A to FIG. 12B As shown, the thermal probe 302 can be directly mounted in the pot. As shown, the pot 1000 can include a bracket 1002 and a handle 1004. The bracket 1002 can be positioned on a side wall 1006 of the pot 1000 and can extend outward from the side wall 1006. The bracket 1002 can include a channel 1008 cast directly into the bracket 1002. The channel 1008 can extend along the bracket 1002 and into the base portion 1010 of the pot 1000. FIG. 12A to FIG. 12B As shown, channel 1008 is configured to receive thermal probe 302. Thermal probe 302 is secured within channel 1008 via handle 1004 connected to bracket 1002. Handle 1004 is secured to bracket 1002 using bolts (not shown) disposed within through-holes 1003 on bracket 1002 and through-holes 1005 on handle 1004. Additionally, handle 1004 includes a recess 1007 shaped to correspond to thermal probe 302, such that handle 1004 is configured to lie flush with bracket 1002 with thermal probe 302 positioned within channel 1008.
[0081] The shield 1012 can be configured to secure the thermal probe 302 within the channel 1008. The shield 1012 is shown shaped to correspond to the outer edge of the bracket 1002 and the base 1010. The shield includes a flat portion 1013 and a curved portion 1015. Additionally, the base 1010 can include a recess 1014 corresponding in shape to the flat portion 1013 of the shield 1012, such that the base 1010 includes a substantially flat bottom surface 1016, with the shield 1012 positioned within the recess 1014. The shield 1012 can be secured within the recess 1014 using pressurization, welding, or brazing techniques. The shield 1012 can be configured to protect the thermal probe 302 when installed within the pot 1000. While the shield is shown for use with the pot 1000, the thermal probe 302 can be secured within the pot's channel without the need for a shield to secure it in place.
[0082] In addition to the securing tabs provided on the lateral sidewalls of the guard, additional tabs may be included to provide a more rigid connection between the guard and the handle. 13A to 13C Another embodiment of a guard 1100 for protecting a heat probe is shown. Guard 1100 is substantially similar to guard 600, and therefore similar components will not be described in detail. Guard 1100 includes a central tab 1102 extending from an upper portion 1104. Tab 1102 can be bent at a 90-degree angle and is configured to be received within a handle. Additionally, tabs 1107 are provided on sidewalls 1109 of guard 1100. Spring tabs 1111 are formed on each of tabs 1107 and are configured to urge guard 1100 into contact with a pot (not shown) when attached to a handle.
[0083] Figure 13C An embodiment of a handle 1106 is shown that is substantially similar to handle 204, and therefore similar components will not be described in detail. Handle 1106 includes a recess 1108 configured in a bottom surface 1110 of handle 1106 and corresponding to the shape of tab 1102. Tab 1102 is received in recess 1108 to reduce rotational movement of guard 1100 relative to handle 1106.
[0084] Alternatively or in addition to the foregoing embodiment, a bracket configured to attach the guard to the handle may be included. In such an embodiment, 14A to 14E 14. As shown, the temperature sensing assembly 300 can be attached to a handle 1402, which can be riveted to a pot body 1404, and then a guard 1406 can be attached to a bracket 1408 mounted to the handle 1402. Aside from any differences described herein, the handle 1402, pot body 1404, and guard 1406 are substantially similar to the handle 204, pot body 100, and guard 600, respectively. The bracket 1408 itself defines one or more holes 1410 at a first end of the bracket 1408 to receive one or more studs 1412 from the handle 1402. Once the studs 1412 have been received, the studs 1412 can then be welded, pressurized to plastically deform and create an interference connection with the bracket (similar to a rivet), or otherwise attached to the bracket 1408.
[0085] A slot 1414 defined by the bracket 1408 is located at the second end of the bracket 1408. The slot 1414 is configured to receive a fastener 1416. In the illustrated embodiment, the fastener comprises a Philips-head screw 1416a and a nut 1416b configured to rest within the slot 1414. The Philips-head screw 1416a is used to secure the guard 1406 to the bracket 1408. In some embodiments, a safety screw, a torque head screw, a slotted screw, or any other screw may be used in place of the illustrated Philips-head screw 1416a. Although primarily described as using a screw and nut configuration, other fastening configurations may be used without departing from the present disclosure. For example, instead of the slot 1414, a threaded hole may be defined by the bracket. Alternatively or additionally, a metal clip, pin, or other fastener may be used in place of the screw.
[0086] In some embodiments, an additional U-shaped spacer 1418 can be added to the handle 1402. The spacer 1418 is configured to rest between the handle 1402 and the guard 1406 and fill any gap that may exist between the handle 1402 and the guard 1406. The spacer can be formed as an integral part of the handle 1402. For example, the spacer 1418 can be pressed or stamped into the handle 1402. Alternatively or additionally, in some embodiments, the spacer 1418 can be added as a separate piece and then attached to the handle, for example, by brazing, welding, adhering, or fastening. The spacer 1418 can define a variety of different profiles. For example, in some embodiments, the spacer 1418 can define an embossed profile. That is, the profile is substantially flat and convex. Alternatively or additionally, the spacer can define a channel configured to receive the guard 1406.
[0087] In some embodiments, for example, Figure 14E In the illustrated embodiment, the guard 1406 includes a tab 1420 that interferes with the handle 1402. This intervening connection helps maintain the guard 1406 substantially flush (e.g., a gap of a few millimeters or less) with the pot body 1404. In some embodiments, during installation, the tab is inserted between the pot body 1404 and the handle 1402 before the screw 1416a is installed to secure the guard 1406.
[0088] Figure 15AAnother embodiment of a temperature sensing assembly 1200 is shown, including a thermal probe 1202 and a measuring meter 1204. Temperature sensing assembly 1200 is similar to temperature sensing assembly 350, and therefore similar components will not be discussed in detail. A coiled or wound bimetallic strip 1206 is disposed within temperature probe 1202 and coupled to an indicator needle (not shown) on measuring meter 1204. The other end of bimetallic strip 1206 is attached near a front end 1208 of thermal probe 1202. Bimetallic strip 1206 can serve as a flexible shaft within thermal probe 1202, eliminating the need for a tension spring, as bimetallic strip 1206 can guide the curved thermal probe 1202 while still transmitting motion from bimetallic strip 1206 to measuring meter 1204.
[0089] In other embodiments, the spring may be used to replace the wire between the extension spring and the bimetallic coil configured in the temperature sensing assembly 350. Figure 15B As shown, temperature sensing assembly 1300 is shown to include a thermal probe 1302 and a measuring meter 1304. Temperature sensing assembly 1300 is similar to temperature sensing assembly 350, and therefore similar components will not be discussed in detail. A coiled or wound bimetallic strip 1306 is disposed within temperature probe 1302, which is coupled to an indicator needle (not shown) on measuring meter 1304 via a spring 1310. The other end of bimetallic strip 1306 is attached near a front end 1308 of thermal probe 1302. Spring 1310 can serve as a flexible shaft within thermal probe 1302 and connect bimetallic strip 1306 to measuring meter 1304, eliminating the need for a wire extending between bimetallic strip 1306 and spring 1310, as spring 1310 can guide the curved thermal probe 1302 while still transmitting motion from bimetallic strip 1306 to measuring meter 1304.
