Description

Technical Field

[0001] This application relates to the field of ovens, and in particular to a temperature controller. Background Art

[0002] Industrial ovens are also known as baking ovens, drying ovens, etc. They are equipment used in industrial production to dry parts or products, usually including gas ovens and electric ovens. An electric oven is an electric heating appliance that uses the heat radiation emitted by electric heating elements to bake products. A temperature controller for adjusting the temperature is provided on the electric oven. According to the drying requirements of different products, the temperature of the electric oven can generally be adjusted within the range of 50 - 250 °C.

[0003] In the related art, the wires inside the oven are first fixedly connected to the terminal of the temperature controller by means of screw locking. The temperature controller is fixed on the oven by means of threaded connection, etc., and then the control panel is installed on the temperature controller, so as to achieve the effect of adjusting the temperature inside the oven outside the control panel.

[0004] In view of the above related art, when the temperature controller needs to be repaired and maintained, it is necessary to first remove the panel, unscrew the screws for fixing the temperature controller, and then unscrew the screws for fixedly connecting the wires. The overall disassembly and assembly process is relatively cumbersome. Content of the Utility Model

[0005] In order to improve the problem that the disassembly and assembly process of the temperature controller is relatively complex and improve the maintenance efficiency of the temperature controller, this application provides a temperature controller.

[0006] The temperature controller provided by this application adopts the following technical solution:

[0007] A temperature controller includes a thermostat main body, a mounting sleeve provided on the oven for mounting the thermostat main body, and a conduction pin for wiring and connecting the oven and the thermostat main body. A conduction seat for the conduction pin to cooperate with is provided on the thermostat main body. The conduction pin has a wiring part for connecting the oven wires and a plugging part for inserting into the conduction seat.

[0008] When the thermostat main body is installed in the mounting sleeve, the plugging part is inserted into the conduction seat to connect the oven and the thermostat main body.

[0009] By adopting the above technical solution, the connection between the thermostat body and the oven becomes simple and quick by using the matching method of the conduction pin and the conduction seat. The way of directly connecting the line to the thermostat body is changed to connecting with the installation shell, and the thermostat body and the installation shell are connected through the conduction pin and the conduction seat, so as to realize the electrical connection between the oven and the thermostat body. When the thermostat body needs to be inspected and maintained, it is only necessary to pull the thermostat body out of the installation shell, avoiding the tedious process of removing and wiring, and improving the inspection efficiency of the temperature controller.

[0010] Furthermore, the mounting sleeve comprises a shell and a back plate that are fixedly connected, the wiring portion is passed through and fixedly connected to the back plate, a locking nut for locking the circuit is threadedly connected to the wiring portion, and the plug-in portion is coaxially and integrally connected to one end of the wiring portion away from the locking nut and is located inside the shell.

[0011] By adopting the above technical solution, the split arrangement between the back plate and the shell can facilitate the assembly of the conduction pin, and the fixed connection between the back plate and the shell can improve the structural stability of the mounting sleeve, making the installation of the thermostat body on the oven more stable. The wiring part is passed through and fixedly connected to the back plate, and a locking nut is provided on the wiring part to ensure the firmness and stability of the line connection and prevent temperature control problems caused by loosening or falling of the line.

[0012] Furthermore, the conductive seat includes a cylinder for inserting the plug-in portion and a convex step provided at the edge of the cylinder and used for clamping and fixing with the thermostat body, and the thermostat body is provided with a stepped hole for setting the cylinder and the convex step countersunk head.

[0013] By adopting the above technical solution, the barrel on the conduction seat allows the plug-in part to be inserted accurately and smoothly, ensuring the accuracy and stability of the line connection. The barrel and convex step structure of the conduction seat match the stepped hole on the thermostat body. The convex step on the edge of the barrel forms a snap-fit ​​fixation with the stepped hole on the thermostat body, which enhances the connection stability between the thermostat body and the conduction seat and prevents loosening or falling off due to vibration or impact.

[0014] Furthermore, a control panel is integrally provided on the thermostat body, and ridges perpendicular to the control panel are provided on both sides of the thermostat body, and sliding grooves for the ridges to be inserted and slide are provided on two opposite inner walls of the shell.

[0015] By adopting the above technical solution, a control panel is integrally provided on the thermostat body. The thermostat body is provided with ribbed edges perpendicular to the control panel on both sides, and the housing is provided with sliding grooves on two opposite inner walls for the ribbed edges to be snapped into and slide. The operator only needs to align the ribbed edges with the sliding grooves and then push the thermostat body to achieve quick installation without using additional tools or complex steps, facilitating the installation of the thermostat body into the mounting housing.

[0016] Further, an elastic member for locking the installation position is provided on the ribbed edge near the control panel side, and a groove for cooperating with the elastic member is provided on the inner wall of the sliding groove of the housing.

[0017] By adopting the above technical solution, an elastic member is provided on the side of the ribbed edge close to the control panel, and a groove for cooperating with the elastic member is provided on the inner wall of the housing. When the ribbed edge slides into the sliding groove and reaches the predetermined position, the elastic member can automatically snap into the groove, thereby realizing the locking of the installation position of the thermostat body, increasing the installation stability and reducing the risk of loosening or falling off caused by vibration or impact.

[0018] Further, an inclined guiding surface for guiding the thermostat body to be inserted into the housing is provided on the ribbed edge on the side away from the elastic member.

[0019] By adopting the above technical solution, the inclined guiding surface is provided on the side of the ribbed edge away from the elastic member, which can play a guiding role during the installation of the thermostat body. When the thermostat body approaches the mounting housing, the inclined guiding surface is equivalent to reducing the width of the side where the ribbed edge is close to the housing, making it easier and more accurate to slide into the sliding groove and improving the installation convenience.

[0020] Further, a rebounder assembly for pushing the thermostat body out of the housing is provided on the housing. The rebounder assembly includes a sleeve, a push rod and a rebounding member. The housing is provided with a mounting hole for the sleeve to be embedded near the control panel side. The rebounding member is slidably mounted in the sleeve. The push rod passes through and slides in the sleeve. A limiting convex portion is provided at one end of the push rod in the sleeve. The end face of the limiting convex portion abuts against the rebounding member. The end of the push rod away from the abutment with the rebounding member protrudes from the sleeve and is used to push the control panel.

[0021] By adopting the above technical solution, when the thermostat is installed on the oven, the control panel is in an embedded state on the outer wall of the oven. When it needs to be disassembled, there is a lack of operating space for the operator to place his hands, and additional auxiliary disassembly tools are required. The setting of the rebounder assembly allows the operator to eject the thermostat body from the shell by simply pressing the control panel when disassembling the thermostat body, which simplifies the disassembly steps and improves the convenience of disassembly. The rebounder assembly includes components such as a sleeve, a push rod and a rebound piece. The components are compact and easy to install, and can be easily integrated into the shell. The rebounder assembly can adapt to thermostat bodies of different weights by adjusting the elastic force of the rebound piece, and adapt to shells of different sizes by changing the length of the push rod. The rebounder assembly has strong adaptability and flexibility.

[0022] Furthermore, the push rod is fixedly connected to a magnetic block at one end away from the rebound member, and a metal block for cooperating with the magnetic block is provided on the control panel. The metal block is embedded in the control panel and fixedly connected to the control panel, and the end face of the metal block close to the magnetic block protrudes from the control panel.

[0023] By adopting the above technical solution, through the cooperation of the magnetic block and the metal block, the operator only needs to use a little force to quickly separate or combine the thermostat body when disassembling or installing the thermostat body, without the need for additional auxiliary tools or complicated operations, which improves the convenience of disassembly and installation. The magnetic block on the push rod and the metal block on the control panel attract each other, and the magnetic fixation enhances the fixation stability of the thermostat body in the shell, ensuring that the thermostat body will not be easily loosened due to vibration or impact during normal use.

[0024] Furthermore, the control panel is provided with a sealing sponge pad on a side close to the thermostat body, the sealing sponge pad is provided with a clearance gap for the thermostat body to pass through, and the sealing sponge pad is provided with a clearance hole for the metal block to pass through at a position adjacent to the clearance gap.

[0025] By adopting the above technical solution, since the end face of the metal block protrudes from the control panel, an assembly gap is formed between the back of the control panel and the shell. The setting of the sealing sponge pad can seal the assembly gap, thereby preventing dust from entering and maintaining the internal cleanliness and normal operation of the temperature controller. The clearance gap and clearance hole on the sealing sponge pad can allow the thermostat body and the metal block to pass smoothly without destroying the integrity of the sealing sponge pad. Since the sealing sponge pad has a certain elastic deformation ability, when the control panel is pressed, the magnetic block on the push rod is adsorbed on the metal block. At this time, the sealing sponge pad is pressed to produce a depression, thereby providing a sliding stroke for the rebounder assembly, which is convenient for disassembly of the thermostat body.

[0026] Furthermore, the housing is provided with heat dissipation grilles.

[0027] By adopting the above technical solution, the heat dissipation grilles can provide a heat dissipation effect for the housing, accelerating the heat exchange speed between the heat released by the thermostat body inside the housing and the outside air, thereby improving the heat dissipation efficiency of the temperature controller, preventing the internal circuit from being damaged due to overheating, and ensuring the stable operation of the temperature controller.

[0028] To sum up, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The cooperation between the conduction pin and the conduction seat simplifies the connection between the thermostat body and the oven, making the installation and disassembly simple and fast. The cylindrical body and the convex step structure of the conduction seat match the stepped hole on the thermostat body to form a stable snap connection and fixation, preventing loosening or falling off caused by vibration or impact;

[0030] 2. The rebounder assembly simplifies the disassembly process. The operator only needs to apply force to press the control panel to pop out the thermostat body, improving the convenience of disassembly. Components such as the rebounder assembly, magnetic attraction block, and metal block have strong adaptability and flexibility, can adapt to thermostat bodies of different weights and sizes, improving versatility and expandability. On the one hand, the sealing sponge pad provides a sliding stroke for the rebounder assembly through elastic deformation, and on the other hand, it can also seal the assembly gap, prevent dust from entering, maintain the internal cleanliness and normal operation of the temperature controller, and improve the safety of the equipment.

[0031] 3. The convex ribs on both sides of the thermostat body cooperate with the sliding grooves on the inner wall of the housing, combined with the locking mechanism of the elastic member and the groove, to increase the installation stability and reduce the risk of loosening or falling off.

Detailed implementation manners

[0038] In order to make the purpose, technical solutions and advantages of the present application clearer and more understandable, the following further elaborates on the present application in conjunction with Figures 1-5 the accompanying drawings and embodiments.

[0039] An embodiment of the present application discloses a temperature controller. In this embodiment, words such as "upper" and "lower" used to express the positional relationship are determined with reference to the placement and installation positions of the temperature controller in its normal use state.

[0040] Referring to Figure 1 and Figure 2 , the number of temperature controllers can be several. In this embodiment, the number of temperature controllers is preferably four and they are arranged at intervals from top to bottom on the industrial oven 0. Each temperature controller can respectively control the temperature of different baking layers in the industrial oven 0.

[0041] Combined with Figure 4 , the temperature controller includes a thermostat body 1, a control panel 12 integrally provided on the thermostat body 1, and a mounting housing 2 that can be embedded in the industrial oven 0. When the thermostat body 1 is installed in the mounting housing 2, the control panel 12 is embedded in the oven 0 and the outer wall of the control panel 12 is flush with the outer wall of the oven 0. A plurality of heat dissipation grilles 214 are provided on the thermostat body 1, so that the thermostat body 1 can dissipate heat in the mounting housing 2.

[0042] Referring to Figure 3 and Figure 4 , the mounting housing 2 includes a housing 21 and a back plate 22. The back plate 22 is fixedly connected to the housing 21 (the fixed connection method is not shown). A plurality of conducting pins 3 are arranged at intervals on the back plate 22. The thermostat body 1 is provided with a conducting seat 4 corresponding to the conducting pins 3 on the side away from the control panel 12.

[0043] The conducting pin 3 has a wiring portion 31 and a plug portion 32 which are coaxially arranged and integrally connected. The wiring portion 31 is passed through the back plate 22 and is directly fixedly connected to the back plate 22. A locking nut 311 for locking the wire is threadedly connected to the wiring portion 31. When the back plate 22 is installed on the housing 21, the plug portion 32 is located inside the housing 21 to cooperate with the conducting seat 4.

[0044] The conducting seat 4 has a barrel 41 for inserting the plug part 32 and a convex step 42 coaxially provided at the edge of the barrel 41. The thermostat body 1 has a stepped hole 11 on the side away from the control panel 12 for the conducting seat 4 to be countersunk and fixed.

[0045] Reference Figure 3 Figure 4 The thermostat body 1 is symmetrically provided with ridges 13 perpendicular to the control panel 12 on both sides, and a slide groove 211 for the ridges 13 to be inserted and slid is provided on two opposite side walls in the housing 21. The ridge 13 is provided with an elastic member 131 for locking the installation position at a position close to the control panel 12. The elastic member 131 in this embodiment is preferably a ball head spring. A groove 212 matching the elastic member 131 is provided in the slide groove 211 on the housing 21. When the thermostat body 1 slides into the housing 21 through the cooperation between the ridge 13 and the slide groove 211, the elastic member 131 is inserted into the groove 212 to lock the installation position of the temperature controller.

[0046] The ridge 13 is provided with an inclined guide surface 132 at one end away from the elastic member 131 . The provision of the inclined guide surface 132 is equivalent to reducing the width of the ridge 13 at the side close to the housing 21 , thereby providing a guiding effect when the ridge 13 enters the slide groove 211 .

[0047] The shell 21 is provided with a rebounder assembly 23 on the side away from the back plate 22 for pushing the thermostat body 1 to pop out. Figure 5 The rebounder assembly 23 includes a sleeve 231, a push rod 232 and a rebound member 233. The rebound member 233 in this embodiment is preferably a spring. The rebound member 233 is coaxially inserted into the sleeve 231. The end of the push rod 232 is coaxially and integrally provided with a limiting protrusion 2321 for preventing it from falling out. The end face of the limiting protrusion 2321 abuts against the rebound member 233.

[0048] The housing 21 is symmetrically provided with mounting holes 213 for inserting the sleeve 231 on both sides, and the sleeve 231 and the housing 21 are interference-fitted to achieve a fixed connection effect. The push rod 232 is coaxially fixedly connected with a magnetic block 2322 at one end away from the limiting protrusion 2321, and a metal block 121 is embedded and fixedly connected at the corresponding position of the magnetic block 2322 on the control panel 12. The metal block 121 can be adsorbed with the magnetic block 2322, and the end of the metal block 121 close to the magnetic block 2322 protrudes from the control panel 12. The operator can achieve the effect of the thermostat body 1 popping out of the housing 21 by pressing the control panel 12.

[0049] Reference Figure 2 and Figure 4 Since the metal block 121 protrudes from the control panel 12, when the thermostat body 1 is installed into the installation sleeve 2, a gap will be left between the control panel 12 and the edge of the shell 21. The control panel 12 is provided with a sealing sponge pad 122 on the side close to the shell 21 for closing the assembly gap, and a clearance notch 1221 for the thermostat body 1 to pass through is formed on the sealing sponge pad 122, and clearance holes 1222 for the metal block 121 to pass through are provided on both sides of the clearance notch 1221.

[0050] The metal block 121 passes through the clearance hole 1222 and is attracted to the magnetic block 2322. When the operator presses the control panel 12 from the outside, the sealing sponge pad 122 is squeezed by the control panel 12 on the shell 21 and becomes concave, thereby providing a sliding stroke for the push rod 232, so that the rebound assembly 23 can be used normally and the thermostat body 1 is ejected from the mounting shell 2.

[0051] The implementation principle of a temperature controller in an embodiment of this application is as follows: The temperature controller consists of a thermostat main body 1, a control panel 12, and a mounting housing 2. Among them, the control panel 12 is integrally provided with the thermostat main body 1, facilitating overall installation and disassembly. The mounting housing 2 includes a housing 21 and a back plate 22, and the back plate 22 is fixedly connected to the housing 21, providing a stable installation foundation. The mounting housing 2 realizes the rapid connection between the thermostat main body 1 and the oven 0 through the cooperation of a conduction pin 3 and a conduction seat 4. The convex ribs 13 on both sides of the thermostat main body 1 cooperate with the sliding grooves 211 on the inner wall of the housing 21, and the thermostat main body 1 is quickly installed and position-locked in the mounting housing 2 by means of an elastic member 131 (such as a ball head spring) being snapped into a groove 212. The rebound assembly 23 (including a sleeve 231, a push rod 232, and a rebound member 233) provided on the housing 21 can, when an operator presses the control panel 12, push the push rod 232 through the elastic force of the rebound member 233, causing the thermostat main body 1 to pop out of the mounting housing 2, thereby realizing convenient disassembly. The magnetic attraction block 2322 on the push rod 232 cooperates with the metal block 121 on the control panel 12, and the thermostat main body 1 is fixed in the housing 21 through magnetic attraction, enhancing the stability and reliability of the connection. The assembly gap between the control panel 12 and the housing 21 is sealed by a sealing sponge pad 122 to prevent dust from entering and keep the interior of the temperature controller clean and operating normally.

[0052] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
