[0047] The existing thermostat has a limited temperature sensing area of ​​the temperature sensing tube, and the temperature sensing surface of the temperature sensing tube is prone to convective heat exchange with the environment during heat transfer, which leads to temperature deviation and low temperature sensing accuracy.

[0048] To improve the temperature sensing accuracy, refer to Figures 1 to 10 The present application provides a temperature sensing tube, a temperature sensing head, a temperature controller and a water dispenser. The temperature sensing tube body 100 is provided with a plurality of curved sections 110 to increase the temperature sensing contact surface and avoid temperature errors in the convection heat exchange between the temperature sensing tube and the external environment. The temperature sensing tube is applied to the temperature controller. The temperature sensing tube includes a temperature sensing tube body 100 and a temperature sensing head 200. As an example, the temperature sensing accuracy can be optimized by improving the temperature sensing tube body 100 and the temperature sensing head 200; or the temperature sensing tube body 100 and the temperature sensing head 200 can be improved to optimize the temperature sensing accuracy.

[0049] In one embodiment, referring to Figures 1 to 6 The temperature sensing tube includes a temperature sensing tube body 100 and a temperature sensing head 200. The temperature sensing head 200 is used to sense temperature. The temperature sensing tube body 100 has a plurality of curved sections 110. The plurality of curved sections 110 are close to each other and form a detection portion 120. The temperature sensing head 200 is arranged at the detection portion 120 of the temperature sensing tube body 100. By improving the structure of the temperature sensing tube and adopting the temperature sensing tube body 100 with a plurality of curved sections 110, the detection portion 120 is in surface contact with water and working parts such as a heating component, an evaporator component or other parts to be sensed, so as to further increase the temperature sensing area, improve the temperature sensing accuracy and temperature sensing stability, and make the temperature sensing result more reliable.

[0050] The temperature sensing tube body 100 is configured to have multiple curved sections 110 to increase the sensing area of ​​the temperature sensing tube and reduce the overall occupied space, making the overall structure more compact and the temperature sensing sensitivity higher, avoiding the problem of limited sensing temperature that may occur when directly using a straight temperature sensing tube, and avoiding the problem of excessive temperature difference due to the influence of the environment on heat transfer; being configured as a curved section 110 can also make the temperature sensing area of ​​the temperature sensing tube more concentrated, and specifically concentrated in the space formed by the curved section 110, avoiding different temperatures sensed in different sensing temperature areas due to heat exchange with the environment, thereby affecting the sensing accuracy.

[0051] Optionally, the curved segment 110 may be, but not limited to, a closed ring, a ring with an opening, a semicircular arc, or any other structure with a certain curvature. When the curved segment 110 is not a closed ring structure, the ends of the curved segment 110 may be formed on the same plane or different planes. The shapes, sizes, etc. of the multiple curved segments 110 may be the same or different, and the multiple curved segments 110 may be, but not limited to, arranged on the temperature sensing tube body 100 in the form of being connected to each other, being independent of each other, etc. For example, when multiple curved segments 110 are connected to each other, the multiple curved segments 110 may be arranged to be connected to each other in sequence, to form a spiral state, a reciprocating snake shape, or any other shape suitable for practical use; or, a connection position is arranged on the curved segment 110, and the connection positions of the multiple curved segments 110 may be the same or different, and the multiple curved segments 110 are connected together through corresponding connection positions to form a spiral, radial, or any other regular or irregular structure suitable for practical use.

[0052] Because the sensing area of ​​the existing temperature sensing tube is not concentrated, the temperature sensing tube body 100 is prone to convective heat exchange with the external environment, resulting in temperature sensing errors. Moreover, after the heat exchange between the temperature sensing tube body and the external environment reaches a thermal equilibrium state, the temperature of the temperature sensing tube no longer changes, causing the thermostat to lose its temperature control function and the temperature control effect is not good. In order to solve the above problems, multiple curved sections 110 of the temperature sensing tube are connected in sequence along the axial direction, so that the multiple curved sections 110 are connected into an aggregate, so that the sensing area of ​​the detection unit 120 is concentrated at the position where the central axis of the multiple curved sections 110 is located, ensuring that the sensing area is not affected by the external environment, avoiding temperature sensing errors caused by thermal equilibrium, and even causing the thermostat to be unable to control the temperature.

[0053] As a specific embodiment of the present application, the curved segment 110 is annular, and a plurality of curved segments 110 are sequentially connected along the central axis thereof to form a cylindrical spiral. Specifically, a plurality of curved segments 110 are sequentially connected along the central axis thereof to form a cylindrical spiral, so that the sensing area of ​​the temperature sensing tube detection part 120 is concentrated on the central axis or near the central axis of the plurality of curved segments 110, and the temperature sensing head 200 is disposed on the detection part 120 which is sequentially connected along the central axis thereof to form a cylindrical spiral, so as to avoid excessive environmental influence on temperature sensing, effectively improve temperature sensing accuracy and temperature sensing stability, and make the temperature sensing result more effective and reliable.

[0054] As another specific embodiment of the present application, the curved segment 110 is annular, and a plurality of curved segments 110 are sequentially connected along the central axis thereof to form a planar spiral. Specifically, a plurality of curved segments 110 are sequentially connected end to end to form any type of planar spiral such as a volute disk, so that the sensing area of ​​the temperature sensing tube detection part 120 is concentrated on the central axis or near the central axis of the plurality of curved segments 110, and the temperature sensing head 200 is arranged on the detection part 120 that is sequentially connected along the central axis thereof to form a planar spiral, so as to avoid excessive environmental influence on temperature sensing. In this way, the contact with the component to be measured can be further expanded to achieve surface contact with the component to be measured, and when applied to a water dispenser, it can be further installed at the bottom of the hot tank and the cold tank of the water dispenser, thereby improving the detection accuracy while reducing the occupied space in the vertical direction, and does not affect the disassembly and assembly of the water dispenser, effectively improving the temperature sensing accuracy and temperature sensing stability, and making the temperature sensing result more effective and reliable.

[0055] To facilitate mass production and processing, in this embodiment, further, refer to Figure 3 , 5 6. The plane spiral shape may be any one of circular, elliptical, square or a combination of shapes suitable for actual processing and use, which is not limited here.

[0056] Further, when a plurality of curved segments 110 are sequentially connected along their central axis to form a cylindrical spiral arrangement, the temperature sensing head 200 is arranged on the detection part 120 in the form of being arranged along its central axis, that is, the temperature sensing head 200 is perpendicular to the plane where the plurality of curved segments 110 are located; when a plurality of curved segments 110 are sequentially connected along their central axis to form a planar spiral arrangement, the temperature sensing head 200 is arranged on the detection part 120 in the form of being perpendicular to the plane where the planar spiral is located. The vertical arrangement of the temperature sensing head 200 can facilitate the fixing of the temperature sensing tube, so that the detection part 120 formed by the temperature sensing tube and the temperature sensing head 200 arranged on the detection part 120 can stably contact the temperature sensing component to be sensed, and avoid the position deviation from affecting the detection effect.

[0057] Based on the structure of the aforementioned temperature sensing tube, when the actual detection accuracy of the temperature controller itself is relatively high or the temperature sensing accuracy requirement for the actual application of the temperature controller is not too high, the temperature sensing head 200 can be optionally arranged at any position of the detection part 120 of the temperature sensing tank body; when the actual detection accuracy of the temperature controller itself is relatively low or the temperature sensing accuracy requirement for the actual application of the temperature controller is relatively high, the temperature sensing head 200 can be optionally arranged at the center line of the detection part 120, or the temperature sensing head 200 can be arranged along the center line of the detection part 120, so as to concentrate the sensed temperature area on the central axis of the temperature sensing tube and the position near the central axis through the arrangement of the bending section 110, and the temperature sensing head 200 can detect centrally and improve the detection accuracy.

[0058] In order to sense the temperature more concentratedly, in one embodiment, the temperature sensing head 200 is arranged close to or at least partially along the center line of the detection part 120. The multiple curved segments 110 of the temperature sensing tube detection part 120 are arranged in sequence along the central axis, so that the multiple curved segments 110 are arranged along its axial direction, so that the temperature sensing area of ​​the temperature sensing tube is more concentrated, and the area for sensing the temperature is concentrated on the central axis of the temperature sensing tube and the position near the central axis. The temperature sensing head 200 is arranged close to or at least partially along the center line of the detection part 120, which can be used to further improve the temperature sensing accuracy and reduce the temperature sensing error.

[0059] It can be understood that the temperature sensing tube of the utility model is applied to a thermostat. Specifically, the thermostat includes a temperature control body 300, and the temperature control body 300 is provided with a ground terminal, a mounting hole 310, a temperature adjustment knob, a copper electrical terminal, etc. Specifically, when applied to a thermostat, in one embodiment, in order to distinguish the portion of the temperature sensing tube body 100 used to achieve connection with the temperature control body 300 and the portion actually used to achieve detection, the temperature sensing tube body 100 is divided into a connecting section and a detection section. The sensing area of ​​the thermostat is determined by the surface of the detection section and the position of the detection section. The connecting section connects the detection section and is used to complete the connection between the detection section and the temperature control body 300, so that the detected temperature can be fed back to the thermostat in a timely manner.

[0060] Specifically, the temperature sensing tube body 100 has a connecting section and a detecting section connected in sequence, the connecting section is used to connect the temperature control body 300, the detecting part 120 is arranged in the detecting section, and the temperature sensing head 200 is arranged at one end of the detecting section away from the connecting section. The temperature sensing head 200 and the detecting part 120 are close to each other and are at least partially arranged along the center line of the detecting part 120.

[0061] The multiple curved sections 110 of the detection part 120 of the temperature sensing tube body 100 are close to each other and form the detection part 120, so that the temperature sensing area of ​​the temperature sensing tube is more concentrated, and specifically concentrated in the space formed by the curved section 110, to avoid different temperatures sensed in different sensing temperature areas due to heat exchange with the environment, which affects the sensing accuracy. The temperature sensing head 200 and the detection part 120 are close to each other. Specifically, the temperature sensing head 200 is connected to the detection part 120 and is at least partially arranged along the center line of the detection part 120, so as to further improve the temperature sensing accuracy and reduce the temperature sensing error.

[0062] The utility model also proposes a temperature sensing head 200, which is applied to a temperature sensing tube, which includes a temperature sensing tube body 100. The temperature sensing tube can optionally adopt any type of existing temperature sensing tube; or, the temperature sensing tube can optionally be the temperature sensing tube of the above embodiment. When the temperature sensing tube adopts the temperature sensing tube in any of the above embodiments, it has the technical features of the temperature sensing tube in the above embodiments, and can at least achieve the beneficial effects of the above temperature sensing tube implementation. To avoid repetition, it will not be repeated here.

[0063] Optionally, the temperature sensing head 200 at least includes a temperature sensing head body, and the temperature sensing head body can be used as the temperature sensing head 200; or, the temperature sensing head 200 includes a temperature sensing head body and a temperature sensing nail 400, and the temperature sensing head body and the temperature sensing nail 400 are optionally configured to be connected as a whole and cannot be disassembled; or the temperature sensing head body and the temperature sensing nail 400 are configured to be a combined structure that is detachably connected by means of clamping, welding, bonding, sleeve connection, etc., and the temperature sensing head body and the temperature sensing nail 400 are connected as a whole as the temperature sensing head 200; or the temperature sensing head body is configured as the temperature sensing nail 400;

[0064] Further, the temperature sensing head body is arranged on the temperature sensing tube body 100, and the temperature sensing head body is used to sense the temperature; the temperature sensing nail 400 includes a nail cap 410 and a nail tube 420, and the nail cap 410 is arranged on the nail tube 420, and is connected to the temperature sensing head body through the nail tube 420. By improving the structure of the temperature sensing head 200, the temperature sensing head 200 provided with the temperature sensing nail 400 is adopted. In order to improve the temperature sensitivity, the temperature sensing nail 400 can be optionally made of metal material, and the nail tube 420 can be specifically set to a hollow structure, so as to be connected to the temperature sensing head body by sleeve connection, or by setting a connection structure such as a buckle and a thread on the nail tube 420, so as to facilitate the connection and fixation of the nail tube 420 to the temperature sensing head body. The contact surface between the temperature sensing nail 400 and the temperature-measured component is increased by the nail cap 410 of the temperature sensing nail 400, so as to further increase the temperature sensing area, optimize the temperature sensing quality, improve the temperature sensing accuracy and temperature sensing stability, and make the temperature sensing result more reliable.

[0065] The nail cap 410 and the nail barrel 420 of the temperature sensing nail 400 can be optionally configured as a non-detachable structure connected as one body, or configured as a combined structure that can be detachably connected by means of clamping, welding, bonding, sleeve connection, etc., which is not limited here. The following embodiments are mainly described by taking the nail cap 410 and the nail barrel 420 as an integrated structure as an example, but are not limited to this.

[0066] The heat transfer between the nail cap 410 of the temperature-sensing nail 400 and the temperature-sensing component can reduce the surface contact thermal resistance. The heat of the temperature-sensing component is transferred to the nail barrel 420 through the nail cap 410 of the temperature-sensing nail 400, and then transferred to the temperature-sensing head 200 through the nail barrel 420, so as to realize temperature sensing and temperature control, and effectively improve the temperature sensing accuracy and the reliability of temperature control.

[0067] In one embodiment, one end of the nail barrel 420 is connected to the nail cap 410, and the other end is provided with a connecting groove 421, and the connecting groove 421 is sleeved on the temperature sensing head body. The nail barrel 420 is sleeved on the temperature sensing head body through the connecting groove 421 to achieve a detachable connection with the temperature sensing head body, so as to detach the temperature sensing nail 400 from the temperature sensing head body when temperature sensing is not required or the temperature sensing accuracy requirement is relatively low, and to sleeve the temperature sensing nail 400 on the temperature sensing head 200 through the connecting groove 421 when temperature sensing is required or the temperature sensing accuracy requirement is relatively high. The temperature sensing nail 400 and the temperature sensing head body are a detachable connection structure, and the required temperature sensing nail 400 can also be adjusted and replaced according to actual needs, which is convenient for use and maintenance.

[0068] Further, in one embodiment, referring to Figure 8 , a center column 4211 is provided in the connection groove 421, and the center column 4211 is used to abut the temperature sensing head body. When the nail barrel 420 is sleeved on the temperature sensing head body through the connection groove 421, the center column 4211 abuts the temperature sensing head body. Through the setting of the center column 4211, on the one hand, the contact area between the temperature sensing nail 400 and the temperature sensing head body can be further increased to further improve the temperature sensing accuracy; on the other hand, positioning can also be achieved. Through the setting of the center column 4211, the temperature sensing nail 400 is further clamped and connected to the temperature sensing head body, so that the temperature sensing nail 400 is stably connected to the temperature sensing head body, and the temperature sensing nail 400 is prevented from falling off or position displacement affecting the actual use effect.

[0069] In one embodiment, the nail barrel 420 is optionally vertically disposed in the middle of the nail cap 410 to form a Figure 7 , 8 , 10 shown in the temperature-sensitive nail 400; or, the nail barrel 420 is vertically disposed on the side of the nail cap 410 to form a Fig. 9 The temperature sensing nail 400 shown

[0070] The thermostat of the utility model can be applied to water dispensers, and specifically applied to hot tanks, cold tanks and other tanks for water dispensers or other devices for storing water. When the temperature sensing tube is mainly used to detect water temperature, the temperature sensing nail 400 can be set to increase the contact surface with water and other temperature-measured components. In order to further increase the temperature sensing contact surface and avoid long-term use of impurities such as scale adhering to the surface of the temperature sensing nail 400 to affect the temperature sensing performance and temperature control performance, in one embodiment, the connection position of the nail barrel 420 and the nail cap 410 is smoothly set. This improves the temperature sensing sensitivity and prolongs the service life of the thermostat.

[0071] It should be noted that the temperature sensing tube is applied to the temperature controller, and the temperature sensing tube includes a temperature sensing tube body 100 and a temperature sensing head 200. As an example, the temperature sensing accuracy can be optimized by improving the temperature sensing tube body 100 and the temperature sensing head 200; or the temperature sensing tube body 100 and the temperature sensing head 200 can be improved to optimize the temperature sensing accuracy.

[0072] The utility model also provides a temperature controller, which includes a temperature control body 300 and a temperature sensing tube.

[0077] Taking the main improvement of the temperature sensing tube body 100 and the temperature sensing head 200 as an example, as another embodiment, the temperature controller adopts a combination of the above examples, that is, the temperature controller includes a temperature control body 300 and a temperature sensing tube, and the temperature sensing tube adopts the temperature sensing tube of the above embodiment. The temperature sensing tube includes a temperature sensing tube body 100 and a temperature sensing head 200, the temperature sensing head 200 is used to sense temperature, the temperature sensing tube body 100 has a plurality of curved sections 110, the plurality of curved sections 110 are close to each other and form a detection part 120, and the temperature sensing head 200 is arranged at the detection part 120 of the temperature sensing tube body 100.

[0078] In this embodiment, the temperature sensing head 200 includes a temperature sensing head body and a temperature sensing nail 400. The temperature sensing head body is arranged on the temperature sensing tube body 100, and the temperature sensing head body is used to sense the temperature; the temperature sensing nail 400 includes a nail cap 410 and a nail tube 420. The nail cap 410 is arranged on the nail tube 420 and is connected to the temperature sensing head body through the nail tube 420.

[0079] In this embodiment, the specific structures of the temperature sensing tube body 100 and the temperature sensing head 200 refer to the aforementioned embodiments. Since the temperature controller of this embodiment adopts all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the aforementioned embodiments. The specific implementation methods of this embodiment refer to the aforementioned embodiments, so they will not be described one by one here.

[0080] Furthermore, the temperature control body 300 is provided with mounting positions such as mounting holes 310, and the thermostat is connected and fixed to any structure of the water dispenser such as the cold tank body of the cold tank or the hot tank body of the hot tank through the mounting positions. In order to facilitate the fixed installation of the thermostat, a thermostat bracket can be optionally provided on the surrounding wall of the hot tank body of the hot tank or the cold tank body of the cold tank, and the thermostat is installed on the thermostat bracket through a screw connection provided on the thermostat body and put into use; or, the tank body is provided with a structure that can be disassembled up and down, and the hot tank (or cold tank) is specifically divided into two parts, the tank body and the bottom cover, one end of the tank body is provided with an opening, and the open end of the tank body is detachably connected to the bottom cover through a connecting piece such as a clamp, and the thermostat is connected and fixed in the tank body through mounting positions such as mounting holes 310 provided on the temperature control body 300, avoiding the need to provide a positioning groove on the tank body to install the thermostat.

[0081] Because the existing thermostat can only be installed horizontally in a form parallel to the bottom of the tank, and needs to be installed in the tank body through an additional positioning groove, and the thermostat fixedly installed in the pipe limits the cold tank and hot tank of the water dispenser to be set as an integral structure that is fixed with the entire water dispenser and cannot be disassembled and cleaned. When the cold tank and hot tank of the water dispenser are set independently of each other, and the cold tank and hot tank are further set to be detachably connected, if the cold tank and hot tank of the water dispenser are set in the vertical direction, the cold tank cannot be directly removed by pulling out, unlocking or releasing the threaded connection due to the installation of the thermostat, which is inconvenient to disassemble, clean and repair. Because the embodiments of the utility model do not limit the installation position and installation direction of the thermostat, the thermostat is detachably installed in the tank body and does not affect the connection between the hot tank and the cold tank. It is suitable for any type of water dispenser and is convenient for disassembly, cleaning and maintenance of the water dispenser.

[0082] As an example, the thermostat can be specifically applied to the hot tank of the water dispenser, and is used to detect the working temperature of the water temperature in the hot tank through a temperature sensing tube. When the hot tank body is provided with a heating component or other working parts, the thermostat is also used to detect the working temperature of the heating component or other working parts. Specifically, it can be set close to such working parts, and a corresponding curved section 110 is set to improve the temperature sensitivity and temperature sensing accuracy to achieve temperature control. As another example, the thermostat can be specifically applied to the cold tank of the water dispenser, and is used to detect the working temperature of the water temperature in the cold tank through a temperature sensing tube. When the cold tank body is provided with an evaporator component or other working parts, the thermostat is also used to detect the working temperature of the evaporator component or other working parts. Specifically, it can be set close to such working parts, and a corresponding curved section 110 is set to improve the temperature sensitivity and temperature sensing accuracy to achieve temperature control.

[0083] The utility model also proposes a water dispenser, which includes a tank body and a thermostat as described in the aforementioned embodiment, wherein the thermostat is installed in the tank body, and the tank body is specifically a hot tank body and / or a cold tank body, that is, the thermostat of the aforementioned embodiment can be installed in the hot tank body, and is used to detect the water temperature in the hot tank or the working temperature of other working parts of the hot tank through a temperature sensing tube to achieve temperature control; and / or, the thermostat of the aforementioned embodiment can be installed in the cold tank body, and is used to detect the water temperature in the cold tank or the working temperature of other working parts of the cold tank through a temperature sensing tube to achieve temperature control.

[0084] Since the water dispenser adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments. The specific implementation of this embodiment refers to the above embodiments, so it will not be described one by one here.

[0085] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
