Description

Technical Field

[0001] This invention relates to a constant temperature dough maker. Background Technology

[0002] A dough mixer is a food processing machine that evenly mixes flour, water, and other ingredients to form dough suitable for various types of pasta. However, during the dough mixing process, the high-speed friction between the mixing tools and the walls of the mixing bowl causes the dough temperature to gradually rise. If the dough temperature exceeds 30°C, it will cause the yeast in the dough to react, or even burn the yeast, rendering it unable to ferment and resulting in unusable, stagnant dough.

[0003] Existing dough mixers also include a cooling water tray, which supports the inner wall of the dough container. The upper end of the tray is fixedly connected to the inner wall of the dough container, and the lower end or side of the tray connects to the outer wall of the dough container to seal the heat exchange chamber. The tray has an inlet hole and an outlet hole spaced apart from the inlet hole along its axial direction. The inlet hole connects to the second end of the inlet channel, and the outlet hole connects to the second end of the outlet channel. The upper end of the tray has an indentation forming an inlet groove and an outlet groove. One end of the inlet groove connects to the inlet hole, and the other end extends through the side wall of the tray and connects to the heat exchange chamber. One end of the outlet groove connects to the outlet hole, and the other end extends through the side wall of the tray and connects to the heat exchange chamber. During operation, the water flow path is: inlet channel → inlet hole → inlet groove → heat exchange chamber → outlet groove → outlet hole → outlet channel. The water flow is guided by inlet and outlet channels to facilitate circulation and stable cooling of the cooling water at the bottom of the drum, ensuring the fluidity of the cooling water located at the bottom of the drum's inner wall. However, this type of tray is prone to water seepage between the inlet and outlet, affecting cooling efficiency. Summary of the Invention

[0033] like Figure 1-8 As shown, this embodiment provides a constant temperature dough maker, including a dough bucket 10, a rotating shaft 30, a disc body 40, a water inlet pipe 50, and a water outlet pipe 60. A heat exchange chamber 20 is formed between the inner wall 101 and the first outer wall 105 of the dough bucket 10. The rotating shaft 30 has a water inlet channel 301 and a water outlet channel 302, the first ends of the water inlet channel 301 and the first ends of the water outlet channel 302 both extending along the axial direction of the rotating shaft 30. The upper end face of the disc body 40 is fixedly connected to the inner wall 101 of the dough bucket 10, and the rotating shaft 30 is fixedly connected to the disc body 40. The lower end face or side face of the disc body 40 is connected to the first outer wall 105 of the dough bucket 10 to cover the heat exchange chamber 20. The disc body 40 has a water inlet hole 401 and a water outlet hole 402 spaced apart from the water inlet hole 401 along its own axial direction. The water inlet hole 401 communicates with the second end of the water inlet channel 301, and the water outlet hole 60 extends along the second end of the water inlet channel 301. The water passage 402 is connected to the second end of the water outlet channel 302. The upper end face of the plate 40 is recessed to form a water inlet groove 403 and a water outlet groove 404. The first end of the water inlet groove 403 is connected to the water inlet passage 401, and the second end of the water inlet groove 403 extends through to the side wall of the plate 40 and is connected to the heat exchange cavity 20. The first end of the water outlet groove 404 is connected to the water outlet passage 402, and the second end of the water outlet groove 404 extends through to the side wall of the plate 40 and is connected to the heat exchange cavity 20. The water inlet pipe 50 is laid on the water inlet groove 403. The first end of the water inlet pipe 50 is connected to the water inlet passage 401, and the second end of the water inlet pipe 50 is connected to the heat exchange cavity 20. The first end of the water outlet pipe 60 is connected to the second end of the water outlet groove 404. The second end of the water outlet pipe 60 is formed by the first end of the water outlet pipe 60 extending upward from the bottom to the top of the heat exchange cavity 20.

[0034] Based on the above structure, by setting up a plate 40, an inlet pipe 50 and an outlet pipe 60, the inlet pipe 50 is pre-embedded in the inlet tank 403, and after the heat exchange chamber 20 is filled with water, the water can overflow through the outlet pipe 60 to the outlet tank 404 for discharge, which can avoid water penetration between the inlet and outlet and ensure constant temperature cooling effect.

[0035] In specific implementation, the water outlet pipe 60 is a pipe welded from the plate body 40, connected to the second end of the water inlet pipe 50, and extending to the top of the heat exchange chamber 20. Even if the second end of the water outlet pipe 60 is higher than the first end of the water outlet pipe 60, water enters the plate body 40 from the first end of the water inlet pipe 50 and flows out of the heat exchange chamber 20 from the second end of the water inlet pipe 50. When the heat exchange chamber 20 is full of water, it can overflow from the second end of the water outlet pipe 60 into the water outlet pipe 60, and enter the water outlet tank 404 through the first end of the water outlet pipe 60, and finally enter the water outlet channel 302 through the water outlet through hole 402 for discharge.

[0036] Preferably, the first end of the water inlet pipe 50 is sealed to the water inlet hole 401, which can effectively prevent water from flowing through each other when water is entering and exiting.

[0037] In this embodiment, the bottom wall of the inner wall 101 of the dough container 10 is fixedly connected to the upper end face of the pan 40. A dough-mixing water-adding hole 103 is provided on the bottom wall of the inner wall 101 of the dough container 10, and the dough-mixing water-adding hole 103 communicates with the water outlet 404. In this way, water in the water outlet 404 can enter the dough container 10 through the dough-mixing water-adding hole 103, ensuring that the temperature of the water used for dough mixing is the same as the internal temperature of the dough container 10, further improving the constant temperature effect.

[0038] In this embodiment, the heat exchange cavity 20 surrounds the entire circumference of the face tank 10 and is formed by at least the bottom and side walls of the inner wall 101 of the face tank 10 and the bottom and side walls of the first outer wall 105 of the face tank 10.

[0039] In this embodiment, the second outer wall 102 of the dough drum 10 is arranged circumferentially around the first outer wall 105 of the dough drum 10 and cooperates with the inner wall 101 of the dough drum 10 to form a heat-insulating cavity 70, which contains a heat-insulating medium. Thus, by setting the heat-insulating cavity 70 outside the heat exchange cavity 20, a heat-insulating effect is achieved, which can further improve the cooling effect.

[0040] In this embodiment, the first end of the second outer wall 102 of the dough container 10 is connected to the side of the plate 40, and the second end of the second outer wall 102 of the dough container 10 is inclined towards the inner wall 101 of the dough container 10 to form a beveled edge 104, which is separated from the inner wall 101 of the dough container 10. In specific implementation, the beveled edge 104 is formed by bending the second end of the second outer wall 102 of the dough container 10 upward relative to the bottom wall. The beveled edge 104 and the inner wall 101 of the dough container 10 form a small gap, which facilitates the fixation of the second outer wall 102 and improves the heat dissipation efficiency. At the same time, the beveled edge 104 can also block the top opening of the heat insulation cavity 70, which can reduce the entry of external dust and other particles into the heat insulation cavity 70.

[0041] In other embodiments, the first end of the second outer wall 102 of the dough container 10 is connected to the lower end face of the plate 40, and the oblique edge 104 is connected to the inner wall 101 of the dough container 10. This improves the fixing effect of the second outer wall 102 of the dough container 10 and seals the heat preservation cavity 70.

[0042] In this embodiment, the first end of the first outer wall 105 of the dough bucket 10 is connected to the lower end face of the plate 40, and the second end of the first outer wall 105 of the dough bucket 10 is separated from the inner wall 101 of the dough bucket 10. Thus, while sealing the heat exchange cavity 20, the installation of the first outer wall 105 can be facilitated.

[0043] In other embodiments, the first end of the first outer wall 105 of the dough bucket 10 is connected to the side of the disc body 40, and the second end of the first outer wall 105 of the dough bucket 10 is connected to the inner wall 101 of the dough bucket 10, thereby improving the fixing effect of the first outer wall 105.

[0044] In this embodiment, the second end of the first outer wall 105 of the dough container 10 is bent towards the inner wall 101 of the dough container 10 to form an upper edge 106, which is spaced apart from the inner wall 101 of the dough container 10. In specific implementation, the upper edge 106 and the inner wall 101 of the dough container 10 form a small gap. By bending the second end of the first outer wall 105 to form the upper edge 106, the top opening of the heat exchange cavity 20 can be blocked, which can prevent cooling water from splashing into the heat insulation cavity 70.

[0045] Preferably, the second end of the first outer wall 105 is bent at 90° toward the inner wall 101 of the dough container 10 to form an upper edge 106, so that the upper edge 106 is parallel to the bottom wall, which can improve the blocking efficiency. Of course, the upper edge 106 can also be an inclined upper edge 106 formed by bending the second end of the first outer wall 105 upward or downward relative to the bottom wall, which can facilitate the manufacturing of the first outer wall 105.

[0046] In other embodiments, the upper edge 106 is connected to the inner wall 101 of the dough drum 10, so that both ends of the first outer wall 105 are fixed to the inner wall 101 of the dough drum 10, thereby improving the fixing effect of the first outer wall 105 and sealing the heat exchange cavity 20.

[0047] In another embodiment, the second end of the first outer wall 105 is connected to the second end of the second outer wall 102, which improves the diversity of installation methods for each outer wall.

[0048] In this embodiment, the water inlet hole 401 and the water outlet hole 402 are symmetrical about the axis of the disc body 40. This facilitates the distribution of the water inlet channel 403 and the water outlet channel 404, and makes the rotation of the disc body 40 more in line with the dynamic balance requirements.

[0049] In this embodiment, the inlet tank 403 and the outlet tank 404 are symmetrical about the axis of the plate 40. This avoids the inlet tank 403 and the outlet tank 404 from intersecting each other, and also makes the rotation of the plate 40 more in line with the dynamic balance requirements. Furthermore, this arrangement ensures that the ports of the inlet tank 403 and the outlet tank 404 are opposite each other, meaning that cooling water enters the heat exchange chamber 20 from the inlet tank 403 and flows for a certain distance before flowing out along the outlet tank 404, thus guaranteeing sufficient cooling effect of the cooling water.

[0050] In this embodiment, the water inlet tank 403 includes several inlet arc segments 405 and several inlet connecting segments 406. The ends of adjacent inlet arc segments 405 are connected through the inlet connecting segments 406. The radius of the several inlet arc segments 405 gradually increases from the inside to the outside along the radial direction of the disc body 40. The water outlet tank 404 includes several outlet arc segments 407 and several outlet connecting segments 408. The ends of adjacent outlet arc segments 407 are connected through the outlet connecting segments 408. The radius of the several outlet arc segments 407 gradually increases from the inside to the outside along the radial direction of the disc body 40. This further improves the cooling effect of the cooling water.

[0051] In this embodiment, both the inlet connection section 406 and the outlet connection section 408 are arc-shaped sections, with the inlet connection section 406 extending radially along the disc body 40 and the outlet connection section 408 extending radially along the disc body 40. The inlet connection section 406 at the outermost edge of the disc body 40 penetrates the side wall of the disc body 40 from the inside out radially. The outlet connection section 408 at the outermost edge of the disc body 40 penetrates the side wall of the disc body 40 from the inside out radially. By making the inlet connection section 406 an arc-shaped section, the installation of the inlet pipe 50 is facilitated, allowing the inlet pipe 50 to fit more closely to the wall of the inlet groove 403. Furthermore, this design not only facilitates the manufacturing of the disc body 40 but also allows the inlet groove 403 and the outlet groove 404 to occupy more area of ​​the disc body 40, ensuring that cooling water flows through more parts of the disc body 40. In other embodiments, the inlet connection section 406 is set as an arc-shaped section and the outlet connection section 408 is set as a straight section, or both the inlet connection section 406 and the outlet connection section 408 are set as straight sections, thereby increasing the diversity of the structural settings of the inlet connection section 406 and the outlet connection section 408.

[0052] In this embodiment, the constant temperature dough machine also includes a water supply pipe and a drain pipe. One end of the water supply pipe is connected to the first end of the water inlet channel 301, and one end of the drain pipe is connected to the first end of the water outlet channel 302. The other ends of the water supply pipe and the drain pipe are respectively connected to the output end and the input end of the refrigeration unit. Thus, cooling water can be input into the disc body 40 through the rotating shaft 30 to effectively cool the dough in the dough bucket 10.

[0053] In this embodiment, the constant temperature dough machine also includes a drive device 80, which drives the rotating shaft 30 to rotate so as to drive the dough bucket 10 to rotate synchronously, thereby improving the dough kneading efficiency.

[0054] Preferably, the drive device 80 includes a motor 801, a drive wheel driven by the motor 801, and a driven wheel 802 driven by the drive wheel. The driven wheel 802 is fixedly sleeved on the rotating shaft 30. The drive wheel can be a gear, sprocket, or other rotating element, as long as it ensures that the rotating shaft 30 is driven, thereby ensuring that the dough drum 10 can rotate. The rotation of the dough drum 10 improves dough kneading efficiency. That is to say, in this invention, the rotating shaft 30 does not necessarily need to be able to rotate; the key point of this invention is its ability to achieve a constant temperature function.

[0055] In practice, the drive device 80 can drive the dough bucket 10 to rotate in both directions, which helps to improve the efficiency of dough mixing.

[0056] In addition, the constant temperature dough maker also includes a base 90, on which the rotating shaft 30 is rotatably mounted, thereby achieving the installation and fixation of the rotating shaft 30 and facilitating its rotation.

[0057] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
