Description

Technical Field

[0001] This utility model relates to the field of temperature controller technology, and in particular to a dual-combination temperature controller. Background Technology

[0002] A thermostat is a series of automatic control components that generate a conducting or disconnecting action based on the temperature changes of the working environment, through physical deformation inside the switch. It is also called a temperature control switch, temperature protector, or temperature controller, and is simply called a thermostat.

[0003] The applicant has discovered at least the following technical problems in the prior art: the existing temperature controllers are usually single-group temperature controllers. Such single-group temperature controllers can usually only realize the normal start-up and shutdown of the equipment. If they fail, they cannot protect the equipment and can easily lead to the equipment burning out. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-unit combined temperature controller to solve the technical problem that existing single-unit temperature controllers can only realize the normal start-up and shutdown of equipment, and cannot protect the equipment if they fail, which can easily lead to equipment burnout. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dual-unit combined thermostat includes a mounting plate and two thermostat units. Both thermostat units are connected to the mounting plate. A client, an external power supply, and the two thermostat units are connected in series. Each thermostat unit includes a disc, and the capacitors of the two discs corresponding to the two thermostat units have different disconnection temperatures.

[0007] Preferably, the thermostat unit further includes an aluminum cover, a pressure plate, a ceramic rod, a spring, a spring rivet, a ceramic housing, a snap-fit ​​terminal, a moving contact, a stationary contact, a pressure plate, a pressure plate rivet, and a connecting terminal. The aluminum cover is connected to the mounting plate. The disc is connected to the inside of the aluminum cover via the pressure plate. One end of the ceramic rod is located above the disc, and the other end extends through the pressure plate and is located below the spring. The spring rivet passes through the spring and is connected to the ceramic housing and the snap-fit ​​terminal, respectively. The snap-fit ​​terminal is electrically connected to the external power supply. The moving contact is connected to the spring. The stationary contact is connected to the pressure plate and is in contact with the moving contact in the start-up state. The pressure plate rivet passes through the pressure plate and is connected to the ceramic housing and the connecting terminal, respectively. The connecting terminal is electrically connected to the client.

[0008] Preferably, it also includes a cover, which covers the outside of the two ceramic housings, and both of the snap-fit ​​terminals are snapped into the cover, which is connected to the client.

[0009] Preferably, the thermostat unit is fixedly connected to the mounting plate.

[0010] Preferably, the mounting plate has mounting holes, and the thermostat unit is fixedly connected to the mounting holes.

[0011] Preferably, the mounting plate is connected to the client.

[0012] Preferably, the two snap-fit ​​terminals are symmetrically arranged relative to the cover, and the two connecting terminals are symmetrically arranged relative to the cover.

[0013] Preferably, the thickness of the disc with a relatively low capacitor disconnection temperature is greater than the thickness of the other disc.

[0014] The beneficial effects of this utility model are as follows: by setting two thermostat units, and the capacitor disconnection temperature of the two discs corresponding to the two thermostat units is different, the thermostat unit with the relatively lower capacitor disconnection temperature can form a thermostat for starting and stopping, and the thermostat unit with the relatively higher capacitor disconnection temperature can form a thermostat for equipment protection.

[0015] When the thermostat used for starting and stopping fails, if the client temperature is higher than the capacitor disconnection temperature of the thermostat's disc, the thermostat will not start, causing the client temperature to continue to rise. When it rises to the capacitor disconnection temperature of the thermostat used for equipment protection, the thermostat used for equipment protection can provide final protection for the equipment, preventing the equipment from burning out at high temperatures and reducing damage to electronic components.

[0016] With the installation plate, two individual thermostats can be fixed simultaneously within a limited installation space, improving space utilization and making the structural design more rational. Attached Figure Description

[0023] 3. Cover. Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be understood that the terms "center," "side," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Reference Figures 1 to 3This utility model provides a dual-unit combined thermostat, including a mounting plate 1 and thermostat units 2. There are two thermostat units 2, and both thermostat units 2 are connected to the mounting plate 1. The client, the external power supply, and the two thermostat units 2 are connected in series. The thermostat unit 2 includes a disc 201, and the capacitors of the two discs 201 corresponding to the two thermostat units 2 have different disconnection temperatures.

[0028] By setting two temperature controller units 2, and the capacitor disconnection temperatures of the two discs 201 corresponding to the two temperature controller units 2 are different, the temperature controller unit 2 with the relatively lower capacitor disconnection temperature can form a temperature controller for starting and stopping, and the temperature controller unit 2 with the relatively higher capacitor disconnection temperature can form a temperature controller for equipment protection.

[0029] The operating principle of the thermostat used for starting and stopping is similar to that of a conventional thermostat, enabling starting and stopping under normal conditions.

[0030] When the thermostat used for starting and stopping fails, if the client temperature is higher than the capacitor disconnection temperature corresponding to the thermostat's disc 201, the thermostat will not start, causing the client temperature to continue to rise. When it rises to the capacitor disconnection temperature of the thermostat's disc 201, which is used for equipment protection, the thermostat used for equipment protection can provide final protection for the equipment, preventing the equipment from burning out at high temperatures and reducing damage to electronic components.

[0031] With the installation plate 1, two thermostat units 2 can be fixed at the same time in a limited installation space, which improves space utilization and makes the structure more reasonable.

[0032] In addition, the specific structural form of the mounting plate 1 can be flexibly set according to actual usage needs, and matched according to the actual installation environment and corresponding installation space position. In this embodiment, the corresponding client is an arc-shaped heating plate, so the mounting plate 1 is also preferably an arc-shaped structural design to form a corresponding matching effect.

[0033] As an optional implementation, the thermostat unit 2 also includes an aluminum cover 202, a pressure plate 203, a ceramic rod 204, a spring 205, a spring rivet 206, a ceramic housing 207, a snap-on terminal 208, a moving contact 209, a stationary contact 210, a pressure plate 211, a pressure plate rivet 212, and a connecting terminal 213.

[0034] The aluminum cover 202 is connected to the mounting plate 1. The disc 201 is connected to the inside of the aluminum cover 202 through the pressure plate 203. One end of the ceramic rod 204 is located above the disc 201, and the other end passes through the pressure plate 203 and is located below the spring 205. The spring rivet 206 passes through the spring 205 and is connected to the ceramic housing 207 and the snap terminal 208 respectively. The snap terminal 208 is electrically connected to the external power supply. The moving contact 209 is connected to the spring 205. The stationary contact 210 is connected to the pressure plate 211 and is in contact with the moving contact 209 in the start state. The pressure plate rivet 212 passes through the pressure plate 211 and is connected to the ceramic housing 207 and the connecting terminal 213 respectively. The connecting terminal 213 is electrically connected to the client.

[0035] When the temperature reaches the set temperature, the disc 201 deforms, lifting the ceramic rod 204. The ceramic rod 204 can touch the spring 205, causing the spring 205 to drive the moving contact 209 to separate from the stationary contact 210.

[0036] As an optional implementation, a cover 3 is also included, which covers the outside of the two ceramic housings 207. Both snap-fit ​​terminals 208 are snapped into the cover 3, and the cover 3 is connected to the client.

[0037] As an optional implementation, the thermostat unit 2 is fixedly connected to the mounting plate 1. Furthermore, the aluminum cover 202 of the thermostat unit 2 can be fixedly connected to the mounting hole 101 by opening a mounting hole 101 on the mounting plate 1. The two can be connected together by compression. Preferably, a draft mold is provided on the mounting hole 101 to improve the connection strength.

[0038] As an optional implementation, the mounting plate 1 is connected to the client. This connection can be further preferably a detachable connection, by providing additional mounting holes on the mounting plate 1 for connection to the client.

[0039] As an optional implementation, the two snap-fit ​​terminals 208 are symmetrically arranged relative to the housing 3, and the two connecting terminals 213 are symmetrically arranged relative to the housing 3. With this arrangement, the two snap-fit ​​terminals 208 are closer to the inside than the two connecting terminals 213, which is beneficial to the structural design of the housing 3, so that the housing 3 can be located in the center and connected to the two snap-fit ​​terminals 208 at the same time.

[0040] As an alternative implementation, the thickness of the disc 201 with a relatively low capacitor disconnection temperature is greater than the thickness of the other disc 201. The disc 201 with a relatively low capacitor disconnection temperature is used for a temperature controller that is used for start-up and shutdown. This temperature controller needs to be used repeatedly for a long time, so the corresponding disc 201 needs to have a certain thickness to improve its service life. The disc 201 with a relatively high capacitor disconnection temperature is used for a temperature controller that is used for equipment protection. This temperature controller is for single use, so the thickness of the corresponding disc 201 can be less than the thickness of the disc 201 that needs to be used repeatedly, which helps to save materials and control costs.

[0041] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
