Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a water injection device and a bread maker. Background Technology

[0002] Most automatic bread makers on the market have an automatic water-filling function. When water is added to the flour, the high-speed water flow easily impacts the flour particles, causing a large amount of flour dust to be stirred up, creating a high-concentration dust environment inside the machine. This dust diffusion not only wastes ingredients, but the scattered flour also easily adheres to the outer wall of the bread maker container and various corners inside the machine, forming hard-to-clean hygiene dead spots that affect the appearance of the equipment and easily breed bacteria.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] Reference Figure 1 According to a first aspect embodiment of the present invention, a water injection device includes a housing 100 and a cover 110. A container 101 is disposed inside the housing 100, and a water tank 102 is located on one side of the container 101. The container 101 is used to stir a mixture of flour and water to form dough. The housing 100 includes an outer shell 1001 and a middle frame 109. The middle frame 109 is fixedly installed on the outer shell 1001 and has two independent cavities. The container 101 and the water tank 102 are detachably installed in the two cavities of the middle frame 109, respectively, so that both the container 101 and the water tank 102 can be disassembled for cleaning.

[0037] Understandably, the water tank 102 has a connecting pipe 106, one end of which is connected to the bottom of the water tank 102 and extends vertically. The cover 110 is pivotally connected to the top of the tank 100. The cover 110 has an annularly arranged water inlet pipe 111, which is connected to the connecting pipe 106. The water inlet pipe 111 has multiple water inlets 112 on one side wall facing the container 101, and these multiple water inlets 112 are spaced apart along the length of the water inlet pipe 111. Simultaneously, along the radial direction of the container 101, the water inlets 112 are close to the inner peripheral wall of the container 101. During water injection, water enters the water injection pipe 111 from the water tank 102 through the connecting pipe 106. The water injection pipe 111 injects water through multiple water injection holes 112 arranged in a ring, thereby forming a ring-shaped water curtain close to the inner peripheral wall of the container 101. During the water injection process, flour dust can be prevented from being lifted and leaving the container 101, reducing raw material waste and reducing the accumulation of flour inside the box 100.

[0038] It is understandable that a hinge 118 is provided between the cover 110 and the box 100. The cover 110 rotates around the hinge 118 to achieve flipping opening and closing. Therefore, the connecting pipe 106 is made of flexible material, such as silicone or polyurethane. Furthermore, the connecting pipe 106 is located on the side of the box 100 where the hinge 118 is located, which reduces the deformation of the connecting pipe 106 when opening and closing the cover 110, thus ensuring a good service life for the connecting pipe 106. At the same time, it reduces the pulling force on the connecting pipe 106, thereby shortening the maximum length of the connecting pipe 106 within the box 100, reducing material consumption and improving the rationality of the space layout.

[0039] Reference Figure 2 It is understood that the water injection pipe 111 has a connecting pipe 117 on its outer periphery, the connecting pipe 117 extends in the horizontal direction, and the connecting pipe 106 has an extension section 107, the extension section 107 extends from the inner peripheral wall of the box 100 to the water injection pipe 111, and the connecting pipe 117 is inserted into the extension section 107 to realize the connection between the extension section 107 and the connecting pipe 117.

[0040] Reference Figure 3 and Figure 4 It is understood that the cover 110 is provided with a support plate 113, and the water injection pipe 111 is installed on the support plate 113 away from the top wall of the container 101. The support plate 113 has multiple connecting holes 114 communicating with the water injection hole 112, allowing water to be injected into the container 101 from the water injection hole 112. Further, in this embodiment, the water injection pipe 111 is annularly arranged on the top of the container 101 and is rectangular; correspondingly, the container 101 has a rectangular cross-section. In other embodiments, the water injection pipe 111 is annularly arranged on the top of the container 101 and is circularly arranged; correspondingly, the container 101 has a circular cross-section.

[0041] Understandably, the support plate 113 has a side edge 119 that extends upwards, and the outer peripheral wall of the side edge 119 can abut against the outer wall of the water injection pipe 111 to facilitate the positioning of the water injection pipe 111 during installation. Furthermore, the support plate 113 has a guide surface 115 inclined to the horizontal plane on the side near the water tank 102, with the guide surface 115 inclined from the connecting hole 114 towards the water tank 102. After water injection, a certain amount of water will remain on the support plate 113. The guide surface 115 allows the water to automatically flow into the water tank 102, preventing excess water from dripping onto the outside of the container 101, thus avoiding water accumulation and reducing the difficulty of cleaning.

[0042] Reference Figure 7It is understood that the maximum center-to-center distance between the two water inlets 112 on the water inlet pipe 111 is S1, and the maximum inner diameter of the container 101 is S2, satisfying: 3 / 4 ≤ S1 / S2 ≤ 5 / 6. In this embodiment, the water inlet pipe 111 is arranged in a ring on the top of the container 101 and is rectangular. The container 101 also has a rectangular cross-section. Therefore, the maximum center-to-center distance between the two water inlets 112 on the water inlet pipe 111 is the center-to-center distance between the two holes on the longest diagonal of the rectangle formed by the water inlet pipe 111; the maximum inner diameter of the container 101 is the length of the longest diagonal of the rectangular cross-section of the container 101. In other embodiments, when the water inlet pipe 111 is arranged in a ring shape, the maximum center-to-center distance between the two water inlets 112 on the water inlet pipe 111 is the center-to-center distance between the two water inlets 112 located on the diameter of the ring.

[0043] Understandably, when the ratio of the maximum center distance S1 between the two water injection holes 112 on the water injection pipe 111 to the maximum inner diameter S2 of the container 101 is less than 3 / 4, the distance between the multiple water injection holes 112 and the inner circumferential wall of the container 101 is too large. During the water injection process, there is a lot of flour between the water curtain and the inner circumferential wall of the container 101. When water is injected, the flour in this area is easily stirred up and overflows to the outside of the container 101, resulting in dust and flour leakage, leading to high material consumption and difficulty in cleaning. When the ratio of the maximum center distance S1 between the two water injection holes 112 on the water injection pipe 111 to the maximum inner diameter S2 of the container 101 is greater than 5 / 6, the distance between the multiple water injection holes 112 and the inner circumferential wall of the container 101 is too small. Since the inner circumferential wall of the container 101 is usually set with a certain inclination, the injected water is easy to flow down along the inner wall of the container 101, resulting in a small contact area between the water and the flour, which easily leads to uneven mixing and clumping, adversely affecting the quality of the bread. Therefore, only when the ratio between the maximum center distance S1 of the two water injection holes 112 on the water injection pipe 111 and the maximum inner diameter S2 of the container 101 satisfies 3 / 4≤S1 / S2≤5 / 6 can the water and flour be in full contact while reducing the amount of flour dust and flour leakage, thus ensuring the quality of production.

[0044] Reference Figure 5 and Figure 6 It is understood that the tank 100 is equipped with a water valve 104 and a water pump 105. The water valve 104 is located at the bottom of the water tank 102, and the water pump 105 is fixedly installed at the bottom of the tank 100. The water valve 104 is used to open and close the water tank 102 to drain water. There is a drain pipe 103 connecting the water valve 104 and the water pump 105. When the water pump 105 is working, it can draw water from the water tank 102 through the drain pipe 103 and transport the water to the water injection pipe 111 through the connecting pipe 106 to realize the water injection process.

[0045] Furthermore, a manifold 108 is provided at the bottom of the water tank 102, and the manifold 108 is inclined from the peripheral wall of the water tank 102 toward the water valve 104. In this embodiment, there are two manifolds 108, and the two manifolds 108 are respectively located on both sides of the water valve 104, so that when the water level is low, the water in the water tank 102 can flow to the water valve 104 and be discharged from the water valve 104, ensuring maximum utilization of the water in the water tank 102, and preventing water accumulation in the water tank 102 from breeding bacteria, thus improving the convenience of cleaning.

[0046] According to an embodiment of the second aspect of this utility model, a bread maker is provided, including the aforementioned water injection device. It is understood that the bread maker incorporates all the technical features of a water injection device, and therefore the bread maker at least includes all the beneficial effects of a water injection device.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
