DETAILED DESCRIPTION

[0025] The exemplary embodiments will be described in detail below with reference to the drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0026] As shown in Figures 1 to 5 , the exemplary embodiments of the present disclosure provide an electronic temperature control device, and further, an electronic temperature control device integrated with an illuminating function. The electronic temperature control device comprises a carrier 1 and a cover 2, the carrier 1 comprises a bearing part 11 for bearing a circuit board 3 and a temperature control panel 12 arranged at the front side of the bearing part 11, wherein the bearing part 11 is provided with a first light-transmitting hole 111, and the temperature control panel 12 extends to the space below the bearing part 11. The cover 2 is made of light-transmitting material, and is arranged at the bottom of the carrier 1, and the front side of the cover 2 is open to define an illuminating cavity together with the temperature control panel 12.

[0027] The carrier 1 can be a one-piece structure, for example, the carrier 11 and the temperature control panel 12 can be integrally injection molded with a flame-retardant material such as HIPS. The circuit board 3 is respectively provided with an illuminating lamp 31 and a temperature indicating lamp 32, and according to actual needs, the illuminating lamp 31 and the temperature indicating lamp 32 can be provided with multiple. The carrier 11 is provided with a first light transmission hole 111, and the opening of the first light transmission hole 111 is directed towards the illuminating lamp 31, so that the illuminating light emitted by the illuminating lamp 31 can be transmitted outward through the first light transmission hole 111. The cover 2 is made of a light-transmitting material, for example, GPPS material, and is arranged at the bottom of the carrier 1, which can play a role of light homogenization.

[0028] The temperature control panel 12 is arranged at the front side of the carrier 11, and it should be noted that here, front and back refer to the direction of the electronic temperature control device after being installed in the refrigerator, and the front side refers to the side facing the user when the refrigerator door is opened. The temperature control panel 12 can be touch or press type, and can display temperature levels. The temperature control panel 12 extends to the space below the carrier 11, and the front side of the cover 2 is open to be able to define an illuminating cavity together with the temperature control panel 12. Specifically, the cover 2 is a half-enclosed structure, including a bottom wall, a rear wall and opposite left and right side walls, when the cover 2 is arranged at the bottom of the carrier 1, the temperature control panel 12 is blocked at the front side of the illuminating cavity, which makes the illuminating light not directly irradiate forward, avoiding direct irradiation stimulating the eyes when the user opens the refrigerator door. At the same time, the illuminating light can be transmitted from the bottom wall and the side wall of the cover 2, compared with the related art, the illuminating device mostly uses a flat light-transmitting plate, and the side wall which can transmit light is additionally provided, thereby providing a larger irradiation range, even if the temperature control device and the illuminating device are integrated, the illuminating effect can be ensured.

[0029] In some embodiments, the carrier 1 and the cover 2 can be assembled by clamping. As shown in Figure 1 and Figure 2 The cover 2 is provided with a first clamping structure 21, and the carrier 1 is provided with a second clamping structure 14, and the first clamping structure 21 and the second clamping structure 14 are clamped and matched to detachably arrange the cover 2 on the carrier 1. The clamping and matching mode is beneficial to simplify the assembly process between the carrier 1 and the cover 2, reduce the cost of parts and labor, and improve the reliability of product assembly.

[0030] Continuing to refer to Figure 3 and Figure 4The first clamping structure 21 can include a first elastic buckle 211 and a first rigid buckle 212. Elasticity here means that deformation can occur during assembly, and rigidity means that deformation cannot occur during assembly. The first elastic buckle 211 is arranged on the bottom wall of the opening side of the cover body 2, and the first rigid buckle 212 is arranged on the rear wall of the cover body 2. The second clamping structure 14 includes a first clamping groove 141 that clamps the first elastic buckle 211 and a second clamping groove 142 that clamps the first rigid buckle 212. That is, the first elastic buckle 211 and the first rigid buckle 212 are arranged in the front-rear direction of the cover body 2.

[0031] Considering that the temperature control panel 12 is located on the front side of the lighting cavity, it is more convenient to install the cover body 2 in the rear-to-front direction. Therefore, the electronic temperature control device provided by the present disclosure sets the first elastic buckle 211 on the bottom wall of the opening side of the cover body 2 and sets the first rigid buckle 212 on the rear wall of the cover body 2, which is more in line with assembly habits and improves assembly efficiency. During installation, the first elastic buckle 211 is clamped into the first clamping groove 141 in the rear-to-front direction of the cover body 2, and then the first elastic buckle 211 is deformed to create space for the first rigid buckle 212 to cooperate with the second clamping groove 142. After the first rigid buckle 212 cooperates with the second clamping groove 142, the first elastic buckle 211 and the first rigid buckle 212 are clamped under the action of elastic restoring force.

[0032] In other embodiments, the first rigid buckle 212 can be replaced by an elastic buckle, or the first elastic buckle 211 can be replaced by a rigid buckle. In addition, the first clamping structure 21 can also be arranged in the left-right direction of the cover body 2. The present disclosure does not limit this.

[0033] The circuit board 3 is provided with a temperature indicating lamp 32 for visual display of the temperature level. The temperature control panel 12 can also be provided with a temperature control button, and each press corresponds to the lighting of a temperature indicating lamp. The circuit board 3 is mostly flat and straight, and considering that the temperature control panel 12 is arranged on the front side of the carrier 11 and the panel surface of the temperature control panel 12 is perpendicular or at an angle relative to the carrier 11.

[0034] To guide the light of the temperature indicating lamp 32 on the circuit board 3 to the temperature control panel 12, as shown in Figure 2 and Figure 4 The temperature control panel 12 is provided with a second light-transmitting hole 121, and the carrier 1 is also provided with a third light-transmitting hole 122 that communicates with the second light-transmitting hole 121 to form a light-transmitting channel. The opening of the third light-transmitting hole 122 faces the temperature indicating lamp 32, so that the light can be guided to the temperature control panel 12 without the need for special design of the circuit board 3 or the use of a flexible circuit board. The third light-transmitting hole 122 can be arranged on the carrier 11, or as shown in Figure 2And Figure 4 In this way, the temperature control panel 12 is provided with a lap portion protruding from the wall surface facing the carrier 1, and the portion of the circuit board 3 provided with the temperature indicator 32 is lapped on the lap portion, and the third light-transmitting hole 122 is provided on the lap portion.

[0035] The electronic temperature control device further comprises a light-transmitting film 5, which can be made of PET, for example. The light-transmitting film 5 is arranged on the temperature control panel 12 and covers the second light-transmitting hole 121, thereby playing a role of dust and water proofing. The light-transmitting film 5 can be adhered to the temperature control panel 12 by means of adhesive tape, for example.

[0036] As an embodiment of assembling the circuit board 3 to the carrier 1, as shown in Figure 2 , the side of the circuit board 3 close to the temperature control panel is screw-connected to the carrier 1, and the carrier 1 is provided with a limiting stop edge 15, which is limitingly stopped at the two L-shaped corners of the side of the circuit board 3 away from the temperature control panel 12, so as to define the mounting space of the circuit board 3. The limiting stop edge 15 can be an L-shaped stop bar integrally formed on the carrier 1, which is used to stop at the two L-shaped corners of the side of the circuit board 3 away from the temperature control panel 12. By arranging the limiting stop edge 15, the mounting of the circuit board 3 is guided, so that the screwing holes on the circuit board 3 are able to be directly opposite the screwing hole positions on the carrier 1, thereby improving the assembly efficiency, and since the limiting stop edge 15 stops the lateral movement of the circuit board 3, the deflection of the circuit board 3 during the screwing of the bolts can be avoided.

[0037] In some embodiments, as shown in Figure 1 and Figure 2 , the electronic temperature control device further comprises a cover 4, which is arranged on the top of the carrier 1, and the carrier 1 is provided with a third clamping structure 13, and the cover 4 is provided with a fourth clamping structure 41, and the third clamping structure 13 and the fourth clamping structure 41 are clamped and matched, so as to detachably arrange the cover 4 on the carrier 1. The clamping and matching mode is advantageous to simplify the assembly process between the carrier 1 and the cover 4. The carrier 1 and the cover 4 can also be connected by means of bolts on the side away from the temperature control panel 12, so as to further improve the reliability of the connection.

[0038] Continuing to refer to Figure 5 , the third clamping structure 13 can comprise a second elastic clasp 131 arranged on one of the left and right side walls of the carrier 1 and a second rigid clasp 132 arranged on the other of the left and right side walls of the carrier 1, and the fourth clamping structure 41 comprises a third clamping groove 411 clamped and matched with the second elastic clasp 131 and a fourth clamping groove 412 clamped and matched with the second rigid clasp 132. That is, the second elastic clasp 131 and the second rigid clasp 132 are arranged in the left-right direction of the carrier 1.

[0039] In the process of installation, the second elastic buckle 131 is buckled into the third buckle slot 411, and then the second elastic buckle 131 is continuously deformed to leave a space for the second rigid buckle 132 to cooperate with the fourth buckle slot 412. After the second rigid buckle 132 cooperates with the fourth buckle slot 412, the second elastic buckle 131 and the second rigid buckle 132 are buckled under the action of elastic restoring force. The second elastic buckle 131 and the second rigid buckle 132 are respectively arranged on the left and right sides of the carrier 1, which is more in line with the assembly habit, thereby improving the assembly efficiency.

[0040] The electronic temperature control device provided by the present disclosure simultaneously integrates temperature control and lighting, and the circuit board 3 can be provided with a strong current module 33 and a weak current module 34. In some embodiments, as shown in Figure 1 The cover 4 is provided with a first via hole 42 for the wire harness of the strong current module 33 to pass through and a second via hole 43 for the wire harness of the weak current module 34 to pass through. This design that respectively routes the wire harness of the strong current module 33 and the wire harness of the weak current module 34 can avoid the wire harness from contacting the circuit board 3 and short-circuiting.
