Description

Technical Field

[0001] This utility model relates to the field of bread machine technology, and in particular to an automatic water adding device for bread machines. Background Technology

[0002] Traditional bread machines require manual pouring of water into a measuring cup, measuring the volume in liters or weighing it with an electronic scale, and then pouring it into the bread pan. This process is complicated, and bread machines only come with one measuring cup. This cup is filled with water first, and then flour is added. This can easily cause flour to stick to the measuring cup because there is water in it, affecting the operation.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide an automatic water-adding device for bread machines that is simple in structure, low in manufacturing cost, easy to use, and highly practical, so as to overcome the shortcomings of the prior art.

[0005] An automatic water-adding device for a bread maker designed for this purpose is characterized by comprising a water tank assembly, a water pump, a nozzle, a bread pan, and an electronic board assembly. The water inlet of the water pump is connected to the water tank assembly, and the water outlet of the water pump is connected to the nozzle. The nozzle is positioned above the opening at the top of the bread pan. The electronic board assembly is electrically connected to the water pump. Water in the water tank assembly is pumped to the nozzle by the water pump, and the nozzle injects water into the bread pan.

[0006] The bread maker includes a body with an inner cavity. A bread pan is placed on the inner cavity. A first detection switch is located on the side of the inner cavity. An electronic board assembly is electrically connected to the first detection switch. When the bread pan is placed in the inner cavity, it acts on the first detection switch to close it.

[0007] The top of the machine body is equipped with a top cover assembly that can be rotated and opened and closed, and a second detection switch is also provided on the top of the machine body. When the top cover assembly rotates and closes, it acts on the second detection switch to close it.

[0008] The water pump's inlet is connected to the water tank assembly via a first pipe. A flow meter is installed on the first pipe, and the electronic board assembly is electrically connected to the flow meter.

[0009] The outlet of the water pump is connected to the nozzle through a second pipe, and a one-way valve is installed on the first or second pipe.

[0010] The nozzle is a straight-through nozzle; or, the nozzle has several spray holes; or, the nozzle is equipped with an aerator or atomizer.

[0011] The water tank assembly includes a water tank and a sealing component. The bottom of the water tank is provided with a water outlet, and the sealing component is provided on the water outlet. The body is provided with a water tank base assembly, which is connected to the first pipe. When the water tank assembly is not placed in the water tank base assembly, the sealing component closes the water outlet. When the water tank assembly is placed in the water tank base assembly, the water tank base assembly acts on the sealing component to move the sealing component upward and open the water outlet, which is connected to the first pipe.

[0012] The sealing component includes a water outlet column and a first sealing ring for closing the water outlet. The first sealing ring is sleeved on the water outlet column. The water tank base assembly includes a base and a water outlet connector. The base is fixed to the machine body, and the water outlet connector is fixed to the base. The water outlet connector is provided with an actuating column and a first connecting column. The first connecting column connects to a first pipe. When the water tank assembly is placed into the water tank base assembly, the actuating column acts on the water outlet column to move the water outlet column and the first sealing ring upward, thereby opening the water outlet. The water outlet is connected to the first pipe through the first connecting column.

[0013] An elastic element is installed between the water column and the water tank. When the water column moves upward, it compresses the elastic element. When the water tank assembly is removed from the water tank base assembly, the water column, under the elastic force of the elastic element, drives the first sealing ring to move downward and reset, and the first sealing ring re-closes the water outlet.

[0014] The water tank base assembly also includes a second sealing ring. A sealing post is provided at the bottom of the water tank, and the water outlet is located inside the sealing post. The second sealing ring is fitted onto the sealing post. After the water tank assembly is placed into the water tank base assembly, a sealed space is formed between the water outlet connector, the sealing post, and the second sealing ring.
