Description

Oven with water supply system

Technical Field

The invention relates to the technical field of oven manufacturing, in particular to an oven with a water supply system.

Background

In domestic cooking ovens, steam cooking is required or the use of water as an ingredient in certain recipes, such as pasta or pizza dough.

Some ovens are equipped with a bowl and a stirrer to which the user can add the solid contents of the food package, during which the oven's pump supplies a predetermined amount of water to obtain the final prepared food product after the cooking or heating procedure.

In such cooking processes, a very precise amount of water must be added to the container or bowl, but it is also necessary to avoid water remaining in the conduit assembly, particularly in the conduits downstream of the pump.

When the water in the conduit assembly may be heated by microwaves or convection through the heating chamber, it is necessary to remove the water downstream from the water pump.

Furthermore, certain recipes require avoiding unnecessary dripping or steaming during the cooking process. Furthermore, water remaining in the piping system can also lead to detrimental results in terms of food safety standards.

Although theoretically, peristaltic pumps, gear pumps or flexible vane pumps can easily reverse the direction of operation of the motor to achieve bi-directional fluid flow in the piping system to eliminate the above drawbacks, they are too costly on average to be used in small appliances such as ovens.

Therefore, how to realize safer water distribution and discharge at lower cost becomes a technical problem to be solved urgently by those skilled in the art.

an electric valve is arranged on the bypass pipeline;

the electric valve and the one-way positive displacement pump are both connected with a control unit and are controlled by the control unit.

Preferably, the one-way positive displacement pump is a diaphragm pump, a vibration pump or a metering pump.

Detailed Description

Examples

As shown in fig. 1 to 3, an oven with a water supply system includes a case 10; a drawer type water receiver 12, a nozzle 20 and a pipeline system 16 are arranged in the box body 10; the lower part of the box body 10 is provided with a seat groove 14 matched with the drawer type water receiver 12; the nozzle 20 is provided at the top of the furnace chamber 10 a.

Wherein, the two ends of the pipeline system 16 are respectively connected with the drawer type water storage device 12 and the nozzle 20;

the piping 16 includes a one-way positive displacement pump 18;

the one-way positive displacement pump 18 is connected with the drawer type water receiver 12 through a first pipeline 16 a; the connection between the one-way positive displacement pump 18 and the nozzle 20 is through a second conduit 16 b;

the ends of the first and second conduits 16a and 16b connected to the unidirectional positive displacement pump 18 are connected to the two ends of the bypass line 16c, respectively;

an electric valve 22 is arranged on the bypass pipeline 16 c;

both the electric valve 22 and the one-way positive displacement pump 18 are connected to a control unit 24, controlled by the control unit 24.

The working principle of the invention is as follows:

the first pipe 16a connects the water reservoir 12 and the diaphragm pump 18, and the second pipe 16b connects the diaphragm pump 18 to the nozzle 20 for supplying water into the oven chamber 10a placed in the oven 10.

When the user initiates the cooking/heating cycle, water is automatically added to the food by opening the one-way positive displacement pump 18 and keeping the electric valve 22 closed.

In the water-filling state, the electric valve 22 is closed and there is no flow in the bypass line 16c, as shown in fig. 2. The amount of water required for the addition of the one-way positive displacement pump 18 is accomplished and, if a flow meter 25 is provided, is controlled by the flow meter 25.

Upon draining, the electro valve 22 is opened, i.e. the bypass line 16c allows flow, and the remaining water in the pipe system 16 flows back to the drawer reservoir 12 by gravity.

In certain embodiments, the unidirectional positive displacement pump 18 is a diaphragm pump, a vibratory pump, or a metering pump.

In some embodiments, the piping of the piping system 16 connecting the drawer-type water reservoir 12 is provided with an automatic valve connection 17;

the automatic valve connection 17 controls whether the pipe between the pipe system 16 and the drawer type reservoir 12 is opened according to whether the drawer type reservoir 12 is completely inserted into the seating groove 14;

when the drawer-type reservoir 12 is fully inserted into the seat slot 14, the automatic valve connection 17 opens the conduit between the pipe system 16 and the drawer-type reservoir 12.

In some embodiments, a flow meter 25 is provided on the first conduit 16a or the second conduit 16 b;

the flow meter 25 sends the collected flow data to the control unit 24.

The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
