Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to an ice cream machine with a cover-opening induction control system. Background Art

[0002] With the development of society and advancements in technology, the use of household appliances in people's lives and work is becoming increasingly prevalent. A small household ice cream maker is an appliance used for making ice cream at home. It primarily utilizes a mixing assembly and a refrigeration system to mix and freeze the ingredients for ice cream into a paste, providing the primary ingredients for making the ice cream. The mixing assembly is a necessary component of existing ice cream makers and is typically located within the maker's barrel. During the mixing process, the mixing assembly must rotate continuously and rapidly to cut and mix the ingredients. To ensure operational safety and prevent users from accidentally touching the rotating mixing assembly and injuring themselves, ice cream makers are typically equipped with a top cover to protect them. However, the top cover and mixing assembly of existing ice cream makers are typically independent components, with their operation and control unrelated. Specifically, opening or closing the top cover does not affect the rotational control of the mixing assembly. Consequently, there is still the possibility of users accidentally touching the mixing assembly and injuring themselves when the maker is operating with the lid open. Therefore, improvements and optimizations to the lid opening control system for ice cream makers are needed to address this technical issue. Utility Model Content

[0003] In view of the above background and the deficiencies of the ice cream machines in the prior art, the present invention provides an ice cream machine with a lid opening sensing control system that is safer and can avoid injuries caused by accidentally touching the stirring assembly. The technical solutions of the present invention are as follows:

[0004] An ice cream machine with a cover-opening sensing control system comprises a main body housing, a top cover assembly, a refrigeration system and a stirring assembly, wherein the refrigeration system and stirring assembly are arranged in the main body housing, and the top cover assembly is mounted on the upper portion of the main body housing. The top cover assembly comprises a top cover, a transparent cover and a control switch; a mounting hole for mounting the transparent cover is provided on the top cover at a position corresponding to the stirring assembly, and the transparent cover is opened and closed in the mounting hole; the control switch is mounted and fixed on the main body housing and electrically connected to the main control board of the ice cream machine for driving and controlling the stirring assembly, and the on and off of the control switch is controlled by the opening and closing of the transparent cover.

[0005] As a further illustration of the present invention, the control switch is an induction switch or a travel switch.

[0006] Furthermore, the induction switch is a magnetically controlled switch, and a magnet block is correspondingly provided on the transparent cover.

[0007] Furthermore, the transparent cover is provided with a magnetic block locking groove, the magnet block is installed in the magnetic block locking groove and a magnet cover covering the magnetic block locking groove is provided.

[0008] Furthermore, the transparent cover is rotatably arranged in the mounting hole, and a latch for positioning the transparent cover is provided on the top cover. The transparent cover is latched into the latch by forward rotation or is released from the latch by reverse rotation.

[0009] Furthermore, the top cover is provided with a card slot along the inner wall of the mounting hole to form the card position, and the outer edge of the transparent cover is provided with a card block corresponding to the card slot.

[0010] Furthermore, the top cover is further provided with a guide rib along the inner wall of the mounting hole, and the clamping slot is provided at one end of the guide rib.

[0011] Beneficial effects of the utility model:

[0012] The ice cream machine of the present invention increases the driving control of the stirring assembly of the ice cream machine by adding a control switch, so that the rotation and stop of the stirring assembly of the ice cream machine are associated with the opening and closing action of the transparent cover. When the transparent cover is closed, the control switch is in a closed state, and the main control board can normally drive and control the operation of the stirring assembly; when the transparent cover is removed or not assembled in place, the control switch is in an open state, and the stirring assembly does not rotate, thereby preventing the stirring assembly from continuing to rotate after the transparent cover assembly is opened, which may cause the user's hand to accidentally reach into the stirring space and cause a risk of cuts, thereby improving the safety of the ice cream machine. The product in actual application is also more popular with consumers. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Example:

[0018] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0020] As attached Figure 1-3 The ice cream machine with a cover-opening sensing control system shown in the figure includes a main body housing 2, a top cover assembly, a refrigeration system and a stirring assembly 8. The refrigeration system and stirring assembly 8 are arranged in the main body housing 2, and the top cover assembly is installed on the upper part of the main body housing 2. The top cover assembly includes a top cover 3, a transparent cover 7 and a control switch; a mounting hole for mounting the transparent cover 7 is provided on the top cover 3 at a position corresponding to the stirring assembly 8, and the transparent cover 7 is opened and closed in the mounting hole; the control switch is mounted and fixed on the main body housing 2 and electrically connected to the main control board 1 of the ice cream machine for driving and controlling the stirring assembly 8. The on and off of the control switch is controlled by the opening and closing of the transparent cover 7. The ice cream maker of this embodiment increases the drive control of the ice cream maker stirring assembly 8 by adding a control switch, so that the rotation and stop of the ice cream maker stirring assembly 8 are associated with the opening and closing action of the transparent cover 7. When the transparent cover 7 is closed, the control switch is in a closed state, and the main control board 1 can normally drive and control the operation of the stirring assembly 8; when the transparent cover 7 is removed or not assembled in place, the control switch is in an open state, and the stirring assembly 8 does not rotate, thereby preventing the stirring assembly 8 from continuing to rotate after the transparent cover 7 is opened, which may cause the user to accidentally reach into the stirring space and cause a cut risk. The safety of the ice cream maker is improved, and the product in actual application is more popular with consumers.

[0021] As a feasible implementation scheme, the control switch can be an induction switch or a travel switch. The control switch of this embodiment is fixedly mounted on the main housing 2, and the transparent cover 7 is relatively movable.

[0022] Whether an induction switch or a forming switch is used as the control switch, feedback control is performed by identifying the relative position of the control switch and the transparent cover 7, that is, the feedback control principle is the same, and there are slight differences in the specific structural design. Generally speaking, using an induction switch as the control switch can achieve contactless detection feedback control with the transparent cover 7, while using a travel switch as the control switch requires a contact-type structural setting. During the opening and closing action of the transparent cover 7, the travel switch can be activated accordingly, so that the opening and closing action of the transparent cover 7 can be judged by the on-off action of the travel switch, and then the driving work of the stirring component 8 is feedback-controlled.

[0023] Specifically, as shown in the accompanying drawings, in one embodiment, the sensing switch is specifically a magnetic switch 4, and a magnet block 6 is correspondingly disposed on the transparent cover 7. Thus, when the transparent cover 7 is open, the magnet block 6 is relatively far from the magnetic switch 4, and the magnetic switch 4 cannot sense magnetic information. Conversely, when the transparent cover 7 is fully closed, the magnet block 6 is relatively close to the magnetic switch 4. At this time, the magnetic switch 4 can detect the magnetic information of the magnet block 6 and can feedback a signal to the main control board 1, thereby executing correct drive control.

[0024] In this embodiment, a magnetic block positioning groove is provided on the transparent cover 7, the magnet block 6 is installed in the magnetic block positioning groove and a magnet cover 5 covering the magnetic block positioning groove is provided. On the one hand, the installation and fixation of the magnet block 6 is realized, which is convenient for disassembly and assembly. On the other hand, the magnet block 6 is sealed, which is more beautiful and does not affect the magnetic signal detection and identification of the magnetic control switch 4.

[0025] As shown in the accompanying drawings, as a feasible implementation method, the transparent cover 7 of this embodiment is rotatably arranged in the mounting hole, and the top cover 3 is provided with a latch for positioning the transparent cover 7. The transparent cover 7 is latched into the latch by rotating forward or released from the latch by rotating backward. Specifically, in order to facilitate operation, the top cover 3 is provided with a latch groove 9 along the inner wall of the mounting hole to form the latch, and the outer edge of the transparent cover 7 is provided with a latch block 10 corresponding to the latch groove 9. In this way, when the transparent cover 7 is closed, when the latch block 10 is rotated to latch into the latch groove 9 and cannot be rotated further, it indicates that the transparent cover 7 has been closed. As mentioned above, when the transparent cover 7 is latched in place, the magnet block 6 on it corresponds to the magnetic control switch 4 on the main body housing 2, ensuring correct feedback control. When the transparent cover 7 needs to be opened, it only needs to be rotated in the reverse direction so that it can be opened and removed.

[0026] In a preferred embodiment, to further optimize the operation of the transparent cover 7, as shown in the accompanying drawings, a guide rib 11 is further provided on the top cover 3 along the inner wall of the mounting hole, and the latching slot 9 is provided at one end of the guide rib 11. The guide rib 11 is located below the latching slot 9. When the transparent cover 7 is placed into the mounting hole, the guide rib 11 provides support and guidance, allowing the transparent cover 7 to be smoothly engaged and disengaged by rotating it forward and backward.

[0027] The design and control principles of this embodiment of the ice cream machine are as follows: a magnetic switch 4 is assembled on the main housing 2, a top cover 3 is installed on the main housing 2, covering the magnetic switch 4, a magnet 6 is inserted into the magnetic retaining groove of the transparent cover 7, and then covered with a magnetic cover 5, forming a transparent cover assembly. When the transparent cover assembly is screwed into the corresponding retaining groove of the top cover 3, the magnetic switch 4 senses the magnetism of the magnet 6 and sends a signal back to the main control board 1, confirming that the transparent cover assembly is properly assembled. The ice cream machine then starts operating, and the stirring assembly 8 rotates. If the transparent cover assembly is removed or not installed in the designated position, the ice cream machine will not start. If it has already started, the stirring assembly 8 will pause and send a signal back to the main control board 1, which will then issue an alarm to remind you, and the machine will automatically shut down after a certain period of time.

[0028] The above description is only for the preferred embodiment of the present invention, and it should not be understood as limiting the claims. The present invention is not limited to the above embodiment, and its specific structure is allowed to be varied. In short, all variations made within the scope of protection of the independent claims of the present invention are also within the scope of protection of the present invention.
