DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
FIG. 1 shows a thermostat of a vending machine includes a securing panel 10, a compressor 20, a heat sink 30, an enforcing member 40, a protecting panel 50, a heat isolation panel 60, two mounting members, an evaporator, and two handles 90. The heat sink 30, the compressor 20, and the evaporator 80 are connected to a vent via a pipe (not shown).
The securing panel 10 includes a securing panel body 11 and an extending portion 13, extending from the securing panel body 11. The extending portion 13 is substantially perpendicular to the securing panel body 11. The securing panel 10 further includes four wheels 15 pivotally mounted to the securing panel body 11.
The enforcing member 40 includes a bottom panel 41, a side panel 43 extending from the bottom panel 41, and two mounting tabs 45 extending from opposite sides of the side panel 43. Each mounting tab 45 defines two through holes 451. A distance is maintained between the mounting tab 45 and the bottom panel 41 for receiving the securing panel body 11. The side panel 43 is substantially parallel to the extending portion 13.
The protecting panel 50 includes a first plate 51 and two second plates 53 extending from the first plate 51. The first plate 51 defines a plurality of first slots 511 and the second plate 53 defines a plurality of second slots 531. The first slots 511 and the second slots 531 are elongated.
The heat isolation panel 60 is substantially perpendicular to the securing panel body 11. The heat isolation panel 60 is substantially parallel to the first plate 51. Each mounting member 70 includes a first mounting portion 71 and a second mounting portion 73, substantially perpendicular to the first mounting portion 71. The first mounting portion 71 defines a first mounting hole 711. The second mounting portion 73 defines two second mounting holes 731. Each mounting member 70 further includes a support portion 75 extending from the first mounting portion 71.
The evaporator 80 includes two side walls 81 and an upper wall 83, connected between the two side walls 81. The upper wall 83 defines a plurality of output openings 831. The two side walls 81 are substantially parallel to each other. The upper wall 83 is substantially perpendicular to the side wall 81. The side wall 81 is substantially perpendicular to the securing panel body 11.
Each handle 90 is secured to one mounting member 70 via a connecting shaft 91. The connecting shaft 91 is secured in the first mounting hole 711 via a screw (not shown). The handle 90 is pivotally mounted to the connecting shaft 91. The connecting shaft 91 defines a cutout 911. The handles 90 are substantially perpendicular to the side wall 81 when the handles 90 are located in a first position. The handles 90 rotate in the cutouts 911 to be located in a second position. At this time, the handles 90 are substantially parallel to the side wall 81. The handles 90 rotate in the cutouts 911 from 0 to 90° (shown in FIG. 3). The handles 90 define a plurality of indents 901. The side wall 81 is substantially perpendicular to the rotation plane of the handle 90.
FIGS. 2 and 3 shows that in assembly, the enforcing member 40 moves toward the securing panel body 11 to enable the securing panel body 11, to be received between the bottom panel 41 and the mounting tabs 45. The bottom panel 41 can be secured to the securing panel body 11 via screws (not shown). At this time, the extending portion 13 of the securing panel 10 is located between the two mounting tabs 45 and contacts the side panel 43. The protecting panel 50 is located on the securing panel body 11 to enable the compressor 20 and the heat sink 30 to be located between two second plates 53. A plurality of screws extend through the protecting panel 50 to be screwed into the trough holes 451, thereby securing the protecting panel 50 to the securing panel body 11. The heat isolation panel 60 contacts the side panel 43 of the enforcing member 40 and is secured to the side panel 43 via fasteners (not shown). The first mounting portions 71 of the two mounting members 70 contact and are secured to the heat isolation panel 60 via fasteners. Each connecting shaft 91 is secured in the first mounting hole 711 via a screw. The handles 90 are pivotally mounted to the connecting shaft 91. The evaporator 80 is placed on the support portions 75 of the mounting members 70. The side wall 81 of the evaporator 80 contacts the first mounting portion 71, and the upper wall 83 contacts the second mounting portion 73. A plurality of screws (not shown) pass through the second mounting holes 731 of the second mounting portions 73 to be screwed to the upper wall 83, thereby securing the evaporator 80 to the mounting members 70.
FIG. 4 shows that in use, when the thermostat needs to be mounted in the vending machine, the handles 90 rotates to the first position, the handles 90 are held and are pushed into the vending machine via the wheels 15 of the securing panel 10. The handles 90 rotate to the second position after the thermostat are mounted in the vending machine.
In one embodiment, the handles 90 are directly pivotally mounted to the mounting members 70, and the heat isolation panel 60 is secured to the securing panel 10 via screws.
FIG. 5 shows that in one embodiment an acute angle is defined between the upper wall 83 of the evaporator 80 and the heat isolation panel 60.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
