Description

Technical Field

[0001] The utility model relates to the technical field of temperature control, in particular to an integrated temperature controller and a soybean milk maker. Background Art

[0002] Thermostats and fuses are important components in household appliances. The former can automatically adjust the working state of the heating mechanism according to the set temperature range, and the latter is used to prevent fire or damage to equipment when the circuit is overloaded or short-circuited.

[0003] In household appliances, two structures, a thermostat and a fuse, are assembled to achieve temperature control and circuit protection. Household appliances of this design have more circuits, a more complex system, and are difficult to maintain. In addition, the two structures are set up separately, and the communication is complicated. When the thermostat fails or an error occurs, the fuse may not be able to disconnect the circuit in time, causing the temperature to exceed the safe range, increasing potential safety risks.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0029] Embodiment 1

[0030] Figure 1 The exploded structure diagram of the integrated thermostat of the utility model is shown. Figure 1, an integrated thermostat, comprising a first connector 2, a fuse mechanism 3, a second connector 4 and a thermal deformation mechanism 5, wherein the first connector 2 comprises a first upper terminal 21 and a first lower terminal 22 close to the first upper terminal 21. When the fuse mechanism 3 is arranged above the first connector 2, the fuse mechanism 3 abuts against the outer side of the first upper terminal 21, and the first upper terminal 21 is elastically deformed under the pressure of the fuse mechanism 3 to fit the first lower terminal 22. When the fuse mechanism 3 is arranged below the first connector 2, the fuse mechanism 3 abuts against the outer side of the first lower terminal 22, and the first lower terminal 22 is elastically deformed under the pressure of the fuse mechanism 3 to fit the first upper terminal 21.

[0031] Please refer to Figure 1 , the second connector 4 includes a second upper terminal 41 and a second lower terminal 42 connected to the second upper terminal 41. When the thermal deformation mechanism 5 is heated, it deforms toward the side close to the second connector 4. When the thermal deformation mechanism 5 is arranged above the second connector 4, the thermal deformation mechanism 5 contacts the inner side of the second lower terminal 42, so that the thermal deformation mechanism 5 directly presses against and pushes the inner side of the second lower terminal 42 when it is thermally deformed, so that the second lower terminal 42 is elastically deformed, the second lower terminal 42 is separated from the second upper terminal 41, the circuit is disconnected, and the temperature is controlled. When the thermal deformation mechanism 5 is arranged below the second connector 4, the thermal deformation mechanism 5 contacts the inner side of the second upper terminal 41, so that the thermal deformation mechanism 5 directly presses against the inner side of the second upper terminal 41 when it is deformed, so that the second upper terminal 41 is elastically deformed, the second upper terminal 41 is separated from the second lower terminal 42, the circuit is disconnected, and the temperature is controlled. The thermal deformation temperature of the thermal deformation mechanism 5 is lower than the fusing temperature of the fuse mechanism 3. It is ensured that the fuse mechanism 3 starts to work and disconnects the circuit when the thermal deformation mechanism 5 fails.

[0032] After the integrated thermostat is connected to the circuit, the second connector 4 can act as a thermostat to adjust the temperature in real time. The first connector 2 can act as a fuse to disconnect the circuit in time when the thermal deformation mechanism 5 fails. The thermostat and fuse are combined into one, reducing installation and parts control.

[0033] The first upper terminal 21 , the first lower terminal 22 , the second upper terminal 41 and the second lower terminal 42 may be various types of connectors known in the art, with a certain elasticity, which can be pushed by the contact 32 and the thermal deformation sheet 52 to produce elastic deformation and transmit current.

[0034] The specific structure of the thermal deformation mechanism 5 is described below:

[0035] Please refer to Figure 1The thermal deformation mechanism 5 includes a connecting rod 51 and a thermal deformation sheet 52, and the connecting rod 51 contacts the inner side of the second upper terminal 41 or the inner side of the second lower terminal 42. The thermal deformation sheet 52 connects the connecting rod 51. When the thermal deformation mechanism 5 is arranged above the second connector 4, the lower end of the connecting rod 51 abuts against the inner side of the second lower terminal 42, and the upper end of the connecting rod 51 abuts against the thermal deformation sheet 52. When the thermal deformation mechanism 5 is arranged below the second connector 4, the upper end of the connecting rod 51 abuts against the inner side of the second upper terminal 41, and the lower end of the connecting rod 51 abuts against the thermal deformation sheet 52. The thermal deformation sheet 52 is fixed on the housing 1, and the thermal deformation sheet 52 is made of a memory metal material, such as a two-way nickel-titanium alloy memory metal with a phase change temperature between 45 degrees Celsius and 90 degrees Celsius. Taking the thermal deformation mechanism 5 at the lower end of the second connector 4 as an example, the thermal deformation sheet 52 is used to restore the high-temperature phase shape when heated. When the temperature is high, the thermal deformation sheet 52 pushes the connecting rod 51, and the connecting rod 51 pushes the inner side of the second upper terminal 41, and the second connector 4 is disconnected. When the thermal deformation sheet 52 is cooled, the thermal deformation sheet 52 rebounds and retracts the connecting rod 51, and the second upper terminal 41 also rebounds, and the second connector 4 is connected. The on and off of the second connector 4 is controlled by temperature.

[0036] The specific structure of the fuse mechanism 3 is described below:

[0037] Please refer to Figure 1 , the fuse mechanism 3 includes a support block 31, a contact 32 and a fuse material. When the fuse mechanism 3 is arranged above the first connector 2, the contact 32 abuts against the first upper terminal 21, the first upper terminal 21 is squeezed to produce an elastic deformation downward, the first upper terminal 21 and the first lower terminal 22 are in contact, and the first connector 2 is connected. When the fuse mechanism 3 is arranged below the first connector 2, the contact 32 abuts against the first lower terminal 22, the first lower terminal 22 is squeezed to produce an elastic deformation upward, the first upper terminal 21 and the first lower terminal 22 are in contact, and the first connector 2 is connected. The fuse material is arranged on the support block 31 and supports the contact 32. The fuse material can be various hot-melt materials known in the prior art, preferably composite silver, and the material of the composite silver can be AgNi20, wherein silver has good corrosion resistance, a wide range of applications, and a low melting temperature, and is suitable for acting as a hot-melt material in household appliances. The conductivity, wear resistance and chemical temperature resistance of the composite silver are further improved, and the first connector 2 can be stably supported before hot melting to ensure the stability of the first connector 2. Taking the fuse mechanism 3 disposed below the first connector 2 as an example, when the temperature rises to the melting point of the fuse material, the contact 32 loses support, the first lower terminal 22 loses the extrusion force and rebounds, the first upper terminal 21 and the first lower terminal 22 are separated, and the first connector 2 is disconnected, achieving fuse.

[0038] The specific structure of the housing 1 is described below:

[0039] Figure 2The three-dimensional structure diagram of the integrated temperature controller of the utility model is shown. Figure 1 and Figure 2 , the first connector 2, the fuse mechanism 3, the second connector 4 and the thermal deformation mechanism 5 are arranged in the housing 1. The housing 1 includes an upper cover 11 and a lower cover 13. The upper cover 11 is provided with a protrusion, and the lower cover 13 is provided with a groove 14 to cooperate with the protrusion, and is matched with screws 12 to stably close the upper cover 11 and the lower cover 13. The housing 1 is provided with a plurality of through holes (not marked in the figure), and the first connector 2 and the second connector 4 extend out of the housing 1 through the through holes, so as to facilitate the first connector 2 and the second connector 4 to be connected to the circuit, simplifying the installation.

[0040] The specific workflow of this embodiment is as follows:

[0041] Take the example in which the fuse mechanism 3 is arranged at the lower end of the first connector 2 and the thermal deformation mechanism 5 is arranged at the lower end of the second connector. After the circuit is connected, when the temperature in the circuit exceeds the set thermal deformation temperature, the thermal deformation sheet 52 deforms and pushes the connecting rod 51, and the connecting rod 51 pushes the inner side of the second upper terminal 41. The second upper terminal 41 elastically deforms upward and separates from the second lower terminal 42, the second connector 4 is disconnected, the circuit is disconnected, and the temperature of the circuit is reduced. After the temperature in the circuit drops to a preset low temperature, the thermal deformation sheet 52 rebounds and retracts the connecting rod 51. The second upper terminal 41 synchronously rebounds and contacts the second lower terminal 42, the second connector 4 is connected, and the circuit is connected.

[0042] When the thermal deformation mechanism 5 fails, the temperature of the circuit continues to rise to the preset fusing temperature, the fusing material melts, the contact 32 loses support, the first lower terminal 22 rebounds after losing the extrusion force, the first lower terminal 22 and the first upper terminal 21 are separated, the first connector 2 is disconnected, and the circuit is disconnected.

[0043] Embodiment 2

[0044] Please refer to Figure 1 The structure and working process of the second embodiment are mostly the same as those of the first embodiment, except that the thermal deformation mechanism 5 is deformed away from the second connector 4 when heated.

[0045] When the thermal deformation mechanism 5 is arranged above the second connector 4, the thermal deformation mechanism 5 presses against the outer side of the second upper terminal 41, the second upper terminal 41 elastically deforms and contacts the second lower terminal 42, and the second connector 4 is connected. When the temperature rises, the thermal deformation mechanism 5 is deformed by heat and moves away from the second connector 4, the second upper terminal 41 loses the squeeze and rebounds upward, the second upper terminal 41 and the second lower terminal 42 are separated, and the second connector 4 is disconnected.

[0046] When the thermal deformation mechanism 5 is arranged below the second connector 4, the thermal deformation mechanism 5 presses against the outer side of the second lower terminal 42, the second lower terminal 42 elastically deforms and contacts the second upper terminal 41, and the second connector 4 is connected. When the temperature rises, the thermal deformation mechanism 5 is thermally deformed away from the second connector 4, the second lower terminal 42 loses the squeeze and rebounds downward, the second upper terminal 41 and the second lower terminal 42 are separated, and the second connector 4 is disconnected.

[0047] Embodiment 3

[0048] Please refer to Figure 1 , the structure and working process of the third embodiment are mostly the same as those of the second embodiment, except that the thermal deformation sheet 52 is a bimetallic sheet. The bimetallic sheet is formed by pressure welding two metal sheets with different expansion coefficients. Optionally, the active layer of the bimetallic sheet is made of an iron-nickel-chromium alloy material with a higher expansion coefficient, and the passive layer is made of an iron-nickel alloy material with a lower expansion coefficient. When heated, the iron-nickel-chromium alloy has a higher expansion coefficient, and its length of thermal elongation is greater than that of the iron-nickel alloy, so the bimetallic sheet will bend and deform to one side of the iron-nickel alloy, thereby controlling the movement of the connecting rod 51 set on the thermal deformation sheet 52 to connect or disconnect the second connector 4.

[0049] Embodiment 4

[0050] Figure 3 The structure diagram of the soybean milk machine of the utility model is shown. Figure 3 Based on the first, second and third embodiments, the fourth embodiment discloses a soybean milk machine, including an integrated temperature controller, a power supply 7 and a heating mechanism 6, wherein the positive electrode of the power supply 7 is connected to the heating mechanism 6 through the first connector 2, and the negative electrode of the power supply 7 is connected to the heating mechanism 6 through the second connector 4. After the temperature of the heating mechanism 6 exceeds the suitable temperature of soybean milk, the second connector 4 is disconnected to disconnect the circuit and reduce the temperature of the heating mechanism 6. After the temperature of the heating mechanism 6 is reduced to a suitable value, the second connector 4 is connected again to control the temperature of the heating mechanism 6. When the thermal deformation mechanism 5 controlling the second connector 4 fails, the temperature of the heating mechanism 6 continues to rise to the fusing temperature, at which time the fusing mechanism 3 controls the first connector 2 to disconnect to protect the circuit and the soybean milk machine. Because the soybean milk machine needs to be heated during operation, the temperature generally reaches more than 100 degrees, or even higher. Considering the heating requirements of the soybean milk machine, and the heat accumulation effect of the thermal deformation sheet 52 and the fusing material, the thermal deformation temperature of the thermal deformation sheet 52 can be 135 degrees, and the fusing temperature of the fusing material can be 227 degrees. The heating requirement of the soybean milk maker is met while limiting its temperature. The temperature difference of nearly 90 degrees between the fusing material and the thermal deformation sheet 52 reduces the probability of the fusing material fusing incorrectly.

[0051] The positive pole of the power source 7 can also be connected to the heating mechanism 6 through the second connector 4 , and the negative pole can be connected to the heating mechanism 6 through the first connector 2 .

[0052] The specific workflow of this embodiment is as follows:

[0053] Take the example in which the fuse mechanism 3 is arranged at the lower end of the first connector 2 and the thermal deformation mechanism 5 is arranged at the lower end of the second connection. The positive pole of the power supply 7 is connected to the heating mechanism 6 through the first connector 2, and the heating mechanism 6 is connected to the negative pole of the power supply 7 through the second connector 4. When the temperature of the heating mechanism 6 exceeds the set thermal deformation temperature, the thermal deformation sheet 52 deforms to push the connecting rod 51, and the connecting rod 51 pushes the inner side of the second upper terminal 41. The second upper terminal 41 elastically deforms upward and separates from the second lower terminal 42, the second connector 4 is disconnected, the circuit is disconnected, and the temperature of the heating mechanism 6 is reduced. After the temperature of the heating mechanism 6 is reduced to the preset low temperature, the thermal deformation sheet 52 rebounds and retracts the connecting rod 51. The second upper terminal 41 synchronously rebounds and contacts the second lower terminal 42, the second connector 4 is connected, and the circuit is connected.

[0054] When the thermal deformation mechanism 5 fails, the temperature of the heating mechanism 6 continues to rise to the preset fusing temperature, the fusing material melts, the contact 32 loses support, the first lower terminal 22 rebounds after losing the extrusion force, the first lower terminal 22 and the first upper terminal 21 are separated, the first connector 2 is disconnected, and the circuit is disconnected.

[0055] It can be seen that the above-mentioned integrated thermostat integrates the thermostat and the fuse, which effectively simplifies the installation and parts control. The above-mentioned soybean milk machine uses an integrated thermostat instead of the thermostat and the fuse, which simplifies the structure of the soybean milk machine and facilitates assembly and subsequent maintenance.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
