[ detailed description of the invention ]
Referring to fig. 1, a refrigeration appliance 1 includes a cabinet 20 defining a plurality of storage spaces (not shown). In the present embodiment, the refrigeration device 1 includes a refrigerating chamber 26 having a storage temperature of zero or more, a variable temperature chamber (not shown), and a freezing chamber (not shown) having a storage temperature of zero or less, which are distributed in this order from top to bottom, wherein the storage temperature of the variable temperature chamber can be adjusted between-16 to 10 degrees, for example. The refrigerating chamber 26, the warming chamber, and the freezing chamber are selectively opened or closed by doors 21, 2, 22, respectively.
It should be understood that the present invention is also applicable to other household appliances provided with a door, such as ovens and the like.
In this embodiment, the doors 21, 22 of the refrigerating compartment 26 and the freezing compartment are provided with insulating layers formed by foaming a thermally insulating foaming agent. The door 2 of the temperature changing chamber is transparent, and when the door 2 is closed, a user can see the articles stored in the temperature changing chamber through the door 2. In another embodiment, the glass mold 3 may be processed to be translucent.
Referring to fig. 2, the door 2 includes a glass module 3. The glass module 3 comprises a plurality of spaced apart glass panes 4, 5, and a space (not shown) for thermal insulation is formed between adjacent glass panes 4, 5. The glass module 3 may comprise two or three glass plates spaced apart from each other.
In the present embodiment, the glass module 3 is an already assembled insulating glass, which includes spacing elements (not shown) disposed along the edges of the glass sheets 4, 5 and between adjacent glass sheets, such that the glass sheets 4, 5 are fixed together at a predetermined distance apart and the space between adjacent glass sheets is closed. The glass module 3 may be filled with an inert gas.
The glass module 3 is fixedly mounted to the frame 6. As shown in fig. 2 and 3, the frame 6 has a square shape and has a stepped portion 23 located inside thereof. The inner glass plate 5 of the glass module 3 is supported on the step portion 23. The glass plate 5 can be fixed to the step 23 by means of an adhesive element 24. Further, a seal 25 is preferably provided between the glass module 3 and the step portion 23 to prevent the internal space of the refrigerator 1 from exchanging heat with the outside through a gap between the glass module 3 and the frame 6.
The door 2 includes cover members 30a, 30b, 30c, 30d fixed to outer sides of the frame 6, respectively. In the present embodiment, the side cover pieces 30a, 30c extending in the longitudinal direction are configured as handles of the door 2.
The frame 6 is formed by a plurality of separate parts joined together. In this embodiment, the frame 6 includes upper and lower frame strips 7, 9 extending in the transverse direction and left and right frame strips 8, 10 extending in the longitudinal direction and connected between the upper frame strips 7, 9. These webs 7, 8, 9, 10 are connected in series at their ends to form a closed frame 6. In the present exemplary embodiment, the webs 7, 8, 9, 10 are made of plastic, preferably ABS material.
In this embodiment the frame strips 7, 8, 9, 10 are straight and each form one side of the frame 6. The upper and lower frame strips 7, 9 and the left and right frame strips 8, 10 have the same structure and dimensions, respectively. Because the transverse width of the glass module 3 is greater than the longitudinal height, the length of the upper and lower frame strips 7, 9 is greater than that of the left and right frame strips 8, 10.
The frame strips 7, 8, 9, 10 on the side facing the interior of the refrigerator 1 can be provided for connecting door seals (not shown) in order to reduce the heat exchange between the interior of the refrigerator 1 and the outside.
The webs 7, 8, 9, 10 comprise end faces 11. The adjacent frame strips 7, 8, 9, 10 are respectively connected with each other through the adjacent end surfaces 11. According to the invention, the adjacent end faces 11 of adjacent webs 7, 8, 9, 10 are fixed to one another by welding, whereby the separate webs 7, 8, 9, 10 are fixed to form the closed frame 6.
By means of welding, there may be no gaps between the frame strips 7, 8, 9, 10 at the joints, which may significantly improve the thermal insulation capability of the frame 6, so that a reduction of the energy consumption of the refrigeration appliance 1 may be expected. Meanwhile, the neat and clean frame is also obviously beneficial to obtaining, because the welding connection mode can not only avoid using additional fixing devices such as screws to fix the frame strips, but also can avoid the problem of uneven gaps between the adjacent frame strips caused by adopting the screws for fixing.
In order to facilitate the manufacture of the webs 7, 8, 9, 10 and to facilitate the positioning of the webs 7, 8, 9, 10 and the associated mould, the end faces 11 of the webs 7, 8, 9, 10 are preferably angled at an angle of 45 degrees to their longitudinal axes.
The webs 7, 8, 9, 10 preferably have the same cross section and the respective cross section is constant. In the present exemplary embodiment, the webs 7, 8, 9, 10 are hollow profiles, preferably extruded parts.
The webs 7, 8, 9, 10 comprise holes 12 which extend in the direction of the respective longitudinal axis. The openings 12 extend through the webs 7, 8, 9, 10 and are exposed at the end faces 11 at the two ends of the webs 7, 8, 9, 10. The cross-section of the bore 12 is at least substantially square.
Referring to fig. 4 and 5, the frame 6 includes a reinforcement member 13 received in the hole 12. The reinforcing elements 13 can be fixed to the respective frame strips 7, 8, 9, 10 by means of screws (not shown).
The reinforcement 13 is a hollow profile, preferably made of plastic. The reinforcement 13 comprises two through holes 14 arranged side by side, the through holes 14 extending parallel to the hole 12. The reinforcement 13 thus comprises four walls 16 parallel to the side walls 15 of the hole 12 and spaced from each other. Since the hole 12 and the through hole 14 have a square cross section, the side wall 15 and the wall 16 have flat surfaces, respectively, and are parallel to each other.
The reinforcing elements 13 are preferably arranged with their end faces flush with the respective end faces 11 of the respective webs 7, 8, 9, 10. The use of the reinforcing element 13 increases the connecting area between adjacent frame strips 7, 8, 9, 10, so that the strength of the connection between the frame strips 7, 8, 9, 10 is increased.
In the embodiment shown in fig. 4, the stiffeners 13 are distributed only in the four corner regions of the frame 6. In particular, two ends of each frame strip 7, 8, 9, 10 are respectively provided with a reinforcing member 13 extending only at two ends of the frame strip 7, 8, 9, 10, and a space is formed between the two reinforcing members 13 of each frame strip 7, 8, 9, 10.
In another embodiment, a reinforcement 13 extends over the entire length of the opening 12 of the respective frame strip 7, 8, 9, 10. Similarly, the end faces of the reinforcing element 13 are exposed to the latter flush with the end faces 11 of the corresponding webs 7, 8, 9, 10.
The door 2 includes a plurality of components, such as covers 30a, 30b, 30c, 30d, which are fixed to the frame 6 as separate parts. These components may be fixedly attached to the frame 6 by fixing means (not shown) such as screws.
In addition, in the embodiment shown in fig. 6, the door 2 includes a mounting strip 17 between the frame 6 and the outer glass pane 4. The mounting bar 17 may be made of metal, such as aluminium. The door 2 has mounting holes 18 formed in the frame strips 7, 8, 9, 10 and the reinforcement 13, the mounting holes 18 being adapted to receive fastening means, such as screws, for fastening the mounting strip 17 to the frame 6. Thus, the screws for fixing the mounting bar 17 pass through one side wall 15 of the hole 12 and the walls 16 of the reinforcement 13. In this way, the strength of the connection between the mounting strip 17, which is a separate component from the frame strips 7, 8, 9, 10, and the frame 6 is increased. Thus, even if the frame strips 7, 8, 9, 10, which are made of plastic and have a small wall thickness, may deteriorate over time, the cooperation of the fixing means with the multi-layer walls 15, 16 ensures that the strength of the connection between the separate element 17 and the frame 6 is still ensured.
In the event that separate components (e.g., the mounting bar 17 and the cover members 30a, 30b, 30c, 30d) are required to carry a greater amount of weight, corresponding fastening means may be passed through the plurality of parallel walls 16 of the stiffener 13 after passing through the side walls 15 of the aperture 12.
The method of manufacturing the door 2 is described in detail below with reference to fig. 7 in conjunction with fig. 2 to 5, and the step of obtaining the frame 6 is repeated.
Firstly, frame strips 7, 8, 9, 10 are provided. This can be achieved by providing a strip of constant cross-section and cutting the strip into strips 7, 8, 9, 10. The strip is preferably obtained by an extrusion process.
In an embodiment where it is not necessary to install the reinforcement 13 in the frame strips 7, 8, 9, 10, the length of each frame strip is cut into a long strip according to the dimensions of the frame 6, so that the length of the frame strip 7, 8, 9, 10 is the same as the dimensions of the corresponding side of the frame 6, and so that the angle between each end face 11 of the cut frame strip 7, 8, 9, 10 and the longitudinal axis of the corresponding frame strip 7, 8, 9, 10 is the same as the design angle, for example 45 degrees.
In an embodiment in which it is desired to mount the reinforcement 13 in the frame strips 7, 8, 9, 10, the length of the frame strips 7, 8, 9, 10 cut from a strip can be made slightly greater than the length of the sides of the frame 6. After the reinforcement 13 is fixed to the corresponding frame strips 7, 8, 9, 10, the excess portions of the frame strips 7, 8, 9, 10 and the reinforcement 13 are removed so that the lengths of the frame strips 7, 8, 9, 10 and the sides of the frame 6 are the same.
After the production of the frame strips 7, 8, 9, 10, the frame strips 7, 8, 9, 10 are fixed in a welding mold (not shown) which is provided in advance. The welding mould preferably has a shape corresponding to the frame, so that the frame strips 7, 8, 9, 10 are fixed to the welding mould in the form of a frame. The welding tool with the frame strips 7, 8, 9, 10 fixed thereto is then placed in a welding machine.
A heated plate is then inserted between the adjacent end faces 11 of the adjacent webs 7, 8, 9, 10. The heated plate is simultaneously in contact with the adjacent end faces 11 of the adjacent webs 7, 8, 9, 10, so that the end faces 11 of the webs 7, 8, 9, 10 are heated and melted. This process preferably lasts for a period of time, for example 1 to 2 minutes, in particular 1 minute.
After the heating plate has been removed, pressure is applied so that the adjacent end faces 11 of the adjacent webs 7, 8, 9, 10 are pressed together. This process preferably lasts for a period of not less than 1 minute, for example 2 minutes. In the manner of pressure welding, the welding area of the frame 6 can be relatively neat.
In alternative embodiments, the webs 7, 8, 9, 10 can also be laser welded or ultrasonically welded.
After the frame 6 together with the welding mold is removed from the welding machine, the frame 6 fixed to the welding mold together with the welding mold is cooled. This can be achieved by means of natural cooling. The frame 6 is preferably cooled to room temperature. This process may last for more than 12 hours. The welding procedure is now complete.
Thereafter, the welding area is repaired and cleaned, if necessary.
In addition, in order to mount some additional components to the frame 6, after the welding procedure is completed, holes 27 (including the mounting holes 18) are drilled in the frame 6. Since the holes are formed after the welding procedure, it is avoided that material deformations around the welding area have an influence on the position and shape of these holes.
After the completion of the manufacture of the frame 6, the glass mold set 3 obtained in advance and other elements are fixed to the frame 6. The glass module 3 can be obtained by manufacturing hollow glass in the prior art.
According to the invention, after the door 2 has been obtained, the door 2 is connected to the box 20 previously obtained for the refrigeration appliance 1, so as to complete the assembly of the refrigeration appliance 1.
