Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a box lamp installation structure of a refrigeration device. Background Art

[0002] For example, refrigeration devices such as refrigerators, mirror cabinets, display cabinets, and vending boxes include a box body and a door body. A box light and a door magnetic switch are provided in the box body, and a permanent magnet is provided in the door body. The box light is lit when the door body is opened, and the box light is extinguished when the door body is closed.

[0003] Since the position of the permanent magnet on the door body is fixed, and thus its relative position with the door magnetic switch is fixed, the door magnetic switch may not be able to accurately sense the magnetic flux of the permanent magnet due to installation deviations of the door magnetic switch in mass production, or deviations in the position of the door body and the box body during transportation, or weakening of the magnetism of the permanent magnet during use. This may cause the box light to malfunction, resulting in the box light not lighting up when the door is opened or not being able to be extinguished when the door is closed. Utility Model Content

[0004] The utility model aims to at least solve the technical problem in the prior art that box lights are prone to malfunction, and proposes a box light installation structure for a refrigeration device, so that the magnetic part can be adjusted in a fixed position of the door body to adapt to the door magnetic switch to avoid the malfunction that the box light cannot be extinguished when the door body is closed.

[0005] The utility model is implemented by the following technical scheme: a box light installation structure of a refrigeration device, the refrigeration device comprises a box body and a door body installed on the opening side of the box body through a rotating assembly, a box light and a door magnetic switch are arranged in the box body; the door body comprises a door body and a door frame located on the side of the door body, and a magnetic member is arranged on the door frame; a first assembly groove is arranged on the inner side surface of the door frame facing the opening side of the box body, the first assembly groove is a horizontal groove with a lateral dimension larger than the magnetic member, the magnetic member is located in the first assembly groove, and the fixed position of the magnetic member in the first assembly groove is adjustable, so that when the opening angle of the door body relative to the box body is less than a preset value α, the magnetic member is within the effective sensing distance of the door magnetic switch, 5°<α≤35°.

[0006] In some preferred embodiments, the effective sensing distance is between 5 mm and 20 mm.

[0007] In some preferred embodiments, the door magnetic switch and the magnetic member are both arranged close to the rotating assembly.

[0008] In some preferred embodiments, the first assembly groove and the door magnetic switch are at the same horizontal height.

[0009] In some preferred embodiments, the magnetic component includes a magnetic body hidden in the first assembly groove and a fixing portion located at the groove of the first assembly groove, the fixing portion is fixedly connected to the magnetic body or is an integral structure, and the fixing portion is fixedly connected to the first assembly groove.

[0010] In some preferred embodiments, the fixing portion is adhesively fixed in the first assembly groove, or the fixing portion is provided with a fixing hole, and a screw is passed through the fixing hole to lock with the bottom of the first assembly groove.

[0011] In some preferred embodiments, a second assembly groove is further provided on the inner side surface of the door frame, and the second assembly groove is located below the first assembly groove; the door seal is inserted into the second assembly groove to seal the door body and the box body.

[0012] In some preferred embodiments, the door seal covers the notch of the first assembly groove so that the magnetic member is hidden.

[0013] In some preferred embodiments, the door magnetic switch is a reed switch or a Hall sensor.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model sets the first assembly groove in the form of a long horizontal groove on the inner side of the door frame, so that the fixed position of the magnetic part in the first assembly groove is adjustable, ensuring that when the door body is opened at a small angle less than a preset value α, the fixed position of the magnetic part in the first assembly groove can be adjusted as needed to match the door magnetic switch on the box body, so that the magnetic part is within the effective sensing distance of the door magnetic switch, thereby ensuring that the box light will be turned off first when the door body is not completely closed. After the door body is completely closed, the distance between the magnetic part and the door magnetic switch is closer, so that the magnetic flux of the magnetic part is larger, and the door magnetic switch has a stronger induction of the magnetic part. Even if the door body moves slightly relative to the box body during long-distance transportation or long-term use, or the magnetism of the magnetic part is weakened due to long-term use, or even the sensing sensitivity of the door magnetic switch is deteriorated, the door magnetic switch will not fail to detect the door switching signal of the magnetic part, thereby greatly improving the reliability of the product.

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0024] The refrigeration devices referred to in the present utility model include but are not limited to refrigerators, cosmetic refrigerators, mirror cabinets, display cabinets, vending boxes and other products.

[0025] Combination Figure 1-Figure 3 As shown, the refrigeration device includes a box body 1 and a door body 2. The door body 2 is installed on the opening side of the box body 1 through a rotating component 3 (such as a hinge); a box light and a door magnetic switch 4 are provided in the box body, and the door magnetic switch 4 is usually a reed switch or a Hall sensor; a magnetic member 5 is provided on the door body 2, so that when the door body 2 is closed, the door magnetic switch 4 can sense the magnetic member 5 and turn off the box light.

[0026] In order to avoid the problem that the box light cannot be accurately extinguished because the door magnetic switch 4 cannot accurately sense the magnetic part 5 when the door body 2 is closed due to assembly deviation of the magnetic part 5 on the door body 2, deviation in the position of the door body 2 and the box body 1 during transportation of the product, or weakening of the magnetism of the magnetic part 5 during use, the utility model optimizes the installation structure of the magnetic part 5 on the door body 2, so that the fixed position of the magnetic part 5 on the door body 2 is adjustable, ensuring that the magnetic part 5 is within the sensing distance range of the door magnetic switch 4 to ensure that the box light can work normally.

[0027] The door body 2 includes a door main body 21 and a door frame 22 located on the side of the door main body 21. The door main body 21 can be made of glass or other materials. The door frame 22 provides sufficient rigid support to the door main body 21 to form a door body 2 with a solid structure.

[0028] Further integration Figure 3 , Figure 4 and Figure 6 The inner side surface of the door frame 22 facing the opening side of the box body 1 is provided with a first assembly groove 221, and the first assembly groove 221 is a horizontal groove with a lateral dimension larger than the magnetic member 5. The magnetic member 5 is located in the first assembly groove 221, and the fixed position of the magnetic member 5 in the first assembly groove 221 is adjustable, so that when the opening angle of the door body 2 relative to the box body 1 is less than a preset value α, the magnetic member 5 is within the effective sensing distance D of the door magnetic switch 4, preferably 5°<α≤35°.

[0029] Considering that the effective sensing distance D of the door magnetic switch 4 is relatively small, the door magnetic switch 4 and the magnetic component 5 are usually arranged close to the rotating assembly 3, so that when the opening angle is less than the preset value α, the magnetic component 5 can be within the effective sensing distance D of the door magnetic switch 4, 5mm≤D≤20mm.

[0030] When the magnetic member 5 is within the effective sensing range of the door magnetic switch 4, the door magnetic switch 4 can sense the magnetism of the magnetic member 5 and cause an electrical state conversion, turning off the box light. Therefore, when the door body 2 is closed relative to the box body 1, the box light can be turned off when the door body is not completely closed, so that the product consistency is good, there will be no critical state, and there will be no failure of not being able to turn off the box light.

[0031] In some preferred embodiments, the first assembly groove 221 and the door magnetic switch 4 are at the same level, which is beneficial to improve the reliability of the cooperation between the two.

[0032] The magnetic member 5 can be inserted into the first assembly groove 221 and fixed in the first assembly groove 221 in an adjustable position by means of gluing or screw locking.

[0033] like Figure 5 As shown, the magnetic part 5 includes a magnetic body 51 hidden in the first assembly groove 221 and a fixing part 52 located at the groove of the first assembly groove 221. The fixing part 52 is fixedly connected to the magnetic body 51 or is an integral structure; a fixing hole 521 is provided on the fixing part 52, and a screw is passed through the fixing hole to lock it with the bottom of the first assembly groove 221.

[0034] When different models of door magnetic switches 4 have different effective sensing distances D, or different magnetic parts 5 have different magnetic flux sizes, the horizontal position of the magnetic part 5 in the first assembly groove 221 can be adjusted to adjust the magnetic part 5 to within the effective sensing distance D of the door magnetic switch 4. By making the fixed position of the magnetic part 5 adjustable to adapt to the door magnetic switch 4, the consistency of the product is improved and the failure rate of the box light failing to be turned off due to assembly errors, transportation factors, etc. is reduced.

[0035] A second assembly groove 222 is also provided on the inner side of the door frame 22, and the second assembly groove 222 is located below the first assembly groove 221. A door seal 23 is inserted into the second assembly groove 222, and the door seal 23 generates elastic deformation between the opening sides of the door body 2 and the box body 1 to improve the sealing performance of the door body 2 and the box body 1 when closed. The door seal 23 covers the notch of the first assembly groove 221, so that the magnetic member 5 is not exposed, thereby ensuring that the overall appearance of the door body 2 is consistent and beautiful.

[0036] like Figure 6 The working principle of the box light shown. The refrigeration device includes a control circuit board for controlling the box light 7, and the box light 7 is usually arranged in the box body 1; the door magnetic switch 4 is electrically connected to the control circuit board, and the control circuit board controls the operation of the box light 7 according to the electrical state of the door magnetic switch 4. For example, when the opening angle between the door body 2 and the box body 1 according to the rotating component 3 is greater than the preset value α, at this time, the magnetic part 5 is not within the effective sensing distance D of the door magnetic switch 4, the door magnetic switch 4 cannot sense the magnetic part 5 and outputs the first electrical state, and the control circuit board allows the box light 7 to be powered on; when the opening angle between the door body 2 and the box body 1 is less than the preset value α, the magnetic part 5 is within the effective sensing distance D of the door magnetic switch 4, the door magnetic switch 4 senses the magnetic part 5 and outputs the second electrical state, and the control circuit board makes the box light 7 lose power and extinguish, thereby ensuring that the box light 7 is in the extinguishing state when the door body 2 is completely closed in the box body 1.

[0037] The utility model improves the structure of the door frame 22 of the door body 2, and sets a first assembly groove 221 as a long horizontal groove on the inner side of the door frame 22, so that the fixed position of the magnetic component 4 in the first assembly groove 221 is adjustable, ensuring that when the door body 2 is opened at a small angle less than a preset value α, the fixed position of the magnetic component 4 in the first assembly groove 221 can be adjusted as needed to match the door magnetic switch 5 on the box body 2, so that the magnetic component 5 is within the effective sensing distance D of the door magnetic switch 4, thereby ensuring that the box light 6 will be turned off first when the door body 2 is not completely closed. After confirming the optimal fixing position of the magnetic part 4 in the first assembly groove 221, the position of the magnetic part 4 is fixed to prevent displacement. Therefore, after the door body 2 is completely closed, the distance between the magnetic part 4 and the door magnetic switch 5 is closer, so that the magnetic flux of the magnetic part 4 is larger, and the door magnetic switch 5 has a stronger induction of the magnetic part 4. Even if the product causes the door body 2 to move slightly relative to the box body 1 during long-distance transportation or long-term use, or the magnetism of the magnetic part 4 is weakened due to long-term use, or even the induction sensitivity of the door magnetic switch 5 is deteriorated, the door magnetic switch 5 will not fail to detect the door opening and closing signal of the magnetic part 4, thereby greatly improving the reliability of the product.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
