DETAILED DESCRIPTION OF THE INVENTION Referring to Figs. 1-3, there is shown the combined sink and cooking unit, generally 10. It includes a sink 12 with a supporting top 15 in which are placed a basin 14 with a drain outlet 13 and a cooking chamber 16. The supporting top 15 has a recessed portion 17. A faucet 18 is provided to supply water to both the basin 14 and the cooking chamber 16. The cooking chamber 16 is-designed to receive various types of cooking utensils, such as the wire basket 24 shown in Fig. 1 and the steamer 26 shown in Fig. 2 with the double boiler 28, the pasta colander 29, and the lid Placed adjacent to the cooking chamber 16 are the control knobs 20 and 22 for controlling electrical current for heating the cooking chamber, as well as opening and closing a drain thereto.

This is seen in conjunction with Figs. 3, 4 and Electrical current is supplied by line 34 which is connected to control box 32. Current from this line will be regulated in the usual manner by switches housed in control box 32 and connected to control knobs 20 and 22. Line 36 is connected to junction box 38 and supplies controlled current to both the heating element 42 and the drain control 44 which controls a drain valve 46.

A housing 40 is provided over heating elements 42. Drain control 44 activates solenoid operated drain valve 46 for draining water from drain 48 and ultimately from the cooking pot 50 of the cooking chamber 16.

Fig. 6 illustrates the attachment'of the cooking chamber 16 with pot 50 to the support top 17. A bolt 52 connected at its head to the shoulder 51 of the pot 50 is fastened to the connector 54 -6with the seal 53 placed between the shoulder 51 and the support top 17. Connector 54 has a support section 56 to which is connected an outer housing 58 for the cooking chamber. At the top of the cooking chamber is an insulating ring 60, the purpose of which is to prevent accidental contact with the top of the cooking pot which can be very hot. A seal 61 is disposed between the insulating ring 60 and the shoulder 51. Vents (not shown) are provided in the ring 60 to permit steam to escape when the chamber 16 is covered. They are preferably positioned at the back of the ring opposite the operator.

Referring to Figs. 7.-10, there is shown a cutting board 62 for. movement in either a side-toside manner or front-to-back manner with respect to basin 14. As seen in Fig. 8, support top includes a front wall 64 and a back wall 65 with supporting surfaces provided by upper tracks or rails 66 and 67, as well as lower rails 68 and 69.

Placed in upper rails 66 and 67 are the support feet 63 of cutting board 62. This affords side-to-side slidable movement in these rails and over the wire basket 70 which is supported in the lower rails 68 and 69. If it is desired to have a front-to-back movement of the cutting board rather than a side-toside movement, this is accomplished by removing the wire basket 70, turning the cutting board 62 900 with placement in the lower supporting surfaces provided by rails 75 and 76 which are provided in the side walls 72 and 73. This is shown in Fig. It should be noted that side wall 73 also provides for an upper rail 74 which is coplanar with recessed surface 17. In effect, upper rails 66, 67 and 74 form a supporting surface or track with the recessed -7surface 17.

Referring to Figs. 11-13, there is shown an alternative embodiment of a cooking unit, generally without the basinand sink but in conjunction with a cooking range 81. This cooking unit includes all of the components.previously described for cooking chamber 16 with similar components designated with the same numbers except followed by the suffix The connection of the cooking chamber to a support is similar to that as previously described with the cooking chamber 16 except that the connection to the recessed surface 17 of the support top 15 includes an additional bolt 86 and nut 87 for connection through the counter top 83. The heating of water in the cooking chamber 16 as controlled by the control knob 20A, as well as the draining of water therefrom by means of the control knob 22A, is as previously described in conjunction with controls knobs 20 and 22.

An important feature of the combined sink and cooking unit 10, as well as that of unit 80, is seen from the fact that the control of heat and drainage is made convenient by the positioning of the control knobs such as 20 and 22 immediately adjacent to the cooking chamber. With the faucet 18 being placed adjacent thereto, the cooking chamber can be filled with water, heated and drained therefrom without having to remove the cooking utensil and the food prepared therein from the cooking pot until it is cooked. A distinct advantage of utilizing the basin 14 and the cutting board 62 is that it allows for both side-to-side and back-to-back movement of the cutting board with respect to the basin. This allows for varying access to the basin at the -8discretion of the operator.

While the cooking chamber 16 and its adjacent controls have been shown in conjunction with a sink basin as can be seen from Fig. 11 embodiment, it can utilize without it and in conjunction with a cooking range. While the insulating ring provides a safety feature, it could be eliminated and still have the advantages of the control feature. However, it is not recommended from a safety standpoint.

In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprising" is used in the sense of "including", i.e. the features specified may be associates with further features in various embodiments of the invention.

It is to be understood that a reference herein to a prior art document does not constitute an admission that the document forms part of the common general knowledge in the art in Australia.
