However, in the prior art, in a case that a refrigerator is provided with a dispenser, the glass panel of the refrigerator has to be provided at a location other than the vicinity of the dispenser such that the glass panel cannot be disturbed by the dispenser. For example, individual glass panels are arranged above and below the dispenser respectively and at locations other than the vicinity of the dispenser (especially not at both sides of it). This arrangement can cause that regions of the front surface of the refrigerator door which are above and below and around the dispenser are made of various materials such that these regions can hardly be in a same plane. Therefore, in the vicinity of the dispenser, the front surface of the refrigerator door looks being divided visually. Furthermore, the glass panels above and below the dispenser being separated from each other may increase the assembling cost of the refrigerator door.

In this embodiment, for example, by means of manipulation of a corresponding one of the switch devices 21, a user can carry out operations such as water dispensing, flake ice dispensing and ice cake dispensing and can turn on a lighting device for illuminating the dispensing chamber 4.

As shown in figures 2 and 3, the freezing compartment door 2 comprises a first wall 10 forming a back surface of the freezing compartment door 2 and a front panel 5 forming a front surface of the freezing compartment door 2. The first wall 10 faces toward the freezing compartment when the freezing compartment door 2 is closed. The freezing compartment door 2 further comprises a second wall 11 located between the first wall 10 and the front panel 5. The second wall 11 is preferably made of metallic sheet.

There is an interval between the second wall 11 and the first wall 10 such that a space is formed between the second wall 11 and the first wall 10 to accommodate a thermally insulated layer 12. The thermally insulated layer 12 is preferably formed by foaming of thermally insulated foam material.

The dispenser 3 comprises a dispenser housing 26, which dispenser housing defines a concave chamber 27 recessed in a front and back direction. The front end opening of the concave chamber 27 is in a substantially quadrangle shape. The second wall 11 is provided with an opening 23 corresponding with the concave chamber 27. The position and the size of the opening 23 substantially correspond to those of the front end opening of the concave chamber 27.

The concave chamber 27 is divided into an upper portion and a lower portion by a partition wall 28. More particularly, a portion of the concave chamber 27 which is below the partition wall 28 is opened at its front end such that a dispensing chamber 4 is formed to receive an additional device. A portion of the concave chamber 27 which is above the partition wall 28 is closed by the control panel 17. An ice discharging opening 30 is provided on the partition wall 28 such that ice stored in the freezing compartment is entered into the portion of the concave chamber 27 which is above the partition wall 28 via an ice transporting chute 29 and then is entered into the dispensing chamber 4 via the ice discharging opening 30. When it is not necessary to transport ice, the ice transporting passage 29 is closed by a closure element 44.

As shown in figure 4, the dispenser housing 26 comprises a mounting edge 31 which is matably attached to the second wall 11. Preferably, the front surface of the mounting edge 31 is pressed against the inner surface of the second wall 11 along the opening 23. Preferably, a sealing device is provided between the front surface of the mounting edge 31 and the rear surface of the second wall 11 so as to prevent foam material from escaping during foaming. Such a sealing device is preferably formed by adhesive tape, which facilitates the dispenser housing 26 being secured on the inner surface of the second wall 11. The dispenser housing 26 comprises a connecting slot 32 arranged around the concave chamber 27. Correspondingly, the second wall 11 comprises a connecting flange 32 extending backwards from the edge of the opening 23. The connecting flange 33 is inserted into the connecting slot 32 such that the dispenser housing 26 is secured on the second wall 11. The dispenser housing 26 does not project beyond the front side of the second wall 11 , and thus partially overlaps with the front surface of the second wall 11. The front panel 5 can be tightly pressed against the front side of the second wall 11. The front panel 5 is explained as follow.

The front panel 5 is made of tempered glass and comprises a through-hole 6 adapted for the dispenser 3. The size and the position of the through-hole 6 substantially correspond to those of the front end opening of the concave chamber 27. In this embodiment, the upper portion of the through-hole 6 is closed by the control panel 17, and the lower portion of the through-hole 6 is constructed as an access to the dispensing chamber 4.

The front panel 5 is preferably bonded to the front surface of the second wall 11 by means of adhesive means, which specially facilitates the front surface of the front wall 5 being completely exposed outwards. Preferably, the adhesive means is a double-face adhesive tape which can implement strong adhesion. In this embodiment, the adhesive means comprises a fist adhesive section 24 arranged at the peripheral edge of the front panel 5 and a second adhesive section 25 arranged along the edge region of the through-hole 6. The first adhesive section 24 and the second adhesive section 25 each comprise a plurality of bar-shaped adhesive tapes which preferably adhere with each other to form a closed-loop adhesive frame, which can prevent foreign matter such as dust from entering between the front panel 5 and the second wall 11.

With respect to the through-hole 6, the front panel 5 is divided into an upper region 7 above the through-hole 6, a lower region 8 below the through-hole 6 and side regions 9a and 9b which each are at a corresponding one of both sides of the through-hole 6 and which connects with the upper region 7 and the lower region 8.

The front panel 5 has an outline in oblong shape. Preferably, the widths of the upper region 7 and the lower region 8 are at least substantially identical with the width of the freezing compartment 2. The sum of the longitudinal lengths of the lower region 7, the upper region 8 and one of the side regions 9a and 9b is substantially equal to the longitudinal height of the door 2 in value. Therefore, the front surface of the second wall 11 can be completely covered by the front panel 5. The front panel 5 has a one -pieced structure such that the upper region 7, the lower region 8 and the side regions 9a and 9b connect with each other without any gap. This can facilitate reducing any possible gap on the front surface of the freezing compartment such that a neat and perfect appearance of the refrigerator can be anticipated.

The lateral width of the through-hole 6 is at least a half of the width of the front panel 5. Preferably, the side regions 9a and 9b are symmetrical with respect to the longitudinal center axis of the front panel 5. In order to ensure that the front panel 5 has a sufficient strength, the lateral sizes of the side regions 9a and 9b are larger than 5 cm, for example larger than 7~8 cm. In this embodiment, the width of the front panel 5 is 40 cm, the width of the through-hole 6 is 24 cm, the width of each of the side regions 9a and 9b is 8 cm. Of course, it is also possible that the lateral sizes of the side regions 9a and 9b are different from each other.

Small holes 41 are provided on the front panel 5 to mount a handle 19 therein. A front end of a handle mounting portion 42 secured on the second wall 11 projects into a corresponding one of the small holes 41 so as to be connected with a connecting root 43 of the handle 19.

As shown in figures 3 and 4, a gap 13 is formed between the front panel 5 and the second wall 11 in a front and back direction. The interval in the front and back direction of the gap 13 is substantially identical to the thickness of each of the fist adhesive section 24 after being pressed and the second adhesive section 25 after being pressed. In this embodiment, the gap 13 is about 1 mm in size.

In an preferred embodiment according to the present invention, the end of a chamber wall 15 of the dispenser housing 26 for defining the concave chamber 27 extends beyond the second wall 11 and projects into the through-hole 6 such that the end of the chamber wall 15 forms a shelter element 14 used to isolate the second wall 11 and the gap 13 from the concave chamber 27. Since the dispensing chamber 4 is formed of a portion of the concave chamber 27, the second wall 11 and the gap 13 are not exposed in the dispensing chamber 4. Preferably, the dispensing chamber wall 15 extends into the through-hole 6 and not beyond the front surface of the front panel 5.

Figure 5 shows a schematic perspective view of a refrigerator 1 ' according to another embodiment of the present invention. As shown in figure 5, the refrigerator Y comprises a refrigerating compartment door 34 which is provided with a table-forming opening 35. The table-forming opening 35 is provided through the refrigerating compartment door 34 in a front and back direction. The table-forming opening 35 is selectively closed or opened by a table-forming door 16 provided on the refrigerating compartment door 34.

The front surface of the refrigerating compartment door 34 is formed by a front panel 36. The front panel 36 is made of glass and has a one -pieced structure. At a location corresponding to the table-forming opening 35, a through-hole 37 is formed on the front panel 36 and its position and size substantially correspond to those of the table-forming opening 35. The lateral width of the through-hole 37 is larger than a half of the total width of the front panel 36. The front panel 36 comprises an upper region 38 above the through-hole 36, a lower region 39 below the through-hole 37 and side regions 40a and 40b which each are located at a corresponding one of both sides of the through-hole 36 and which connect with the upper region 38 and the lower region 39. Therefore, the front surface of the refrigerating compartment door 34 which comprises the surrounding area of the table-forming opening 35 can be made of only a piece of glass panel. This facilitates to solve the technical problem that material is not unified and connect seams are excessive in a case that the refrigerating compartment door 34 provided with the table-forming door 16 is made of glass panel.
