Description

Technical Field

[0001] This utility model relates to the field of food drying machine technology, and in particular to a household food drying machine. Background Technology

[0002] To extend shelf life, facilitate storage and transportation, and improve quality and taste, many freshly harvested foods require drying. For example, with increasing consumer demand for healthy foods, dried mushrooms, as a low-fat, high-protein, and fiber-rich food, are gaining popularity. Dried mushrooms can be eaten directly or used as cooking ingredients, offering greater convenience. Many small processing plants and households have a need for dried mushrooms. Current food dryers typically use heating elements and fans at the bottom of a drying chamber to blow hot air upwards to dry the food placed on top. The air inside the chamber is only externally circulated; external air is continuously introduced, heated, and then rises to dry the food before being expelled. This results in low heat utilization and generally low drying efficiency. Furthermore, the limited space for the heating elements restricts the overall heating temperature within the chamber, and the effective utilization of the drying space in the vertical direction is also low. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide a household food dryer with better drying efficiency, higher effective space utilization, and better ease of use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A household food dryer includes a cabinet, in which a vertical partition is provided. The upper and lower ends of the vertical partition are respectively spaced from the top and bottom walls of the cabinet. The vertical partition divides the internal space of the cabinet into a communicating drying chamber and a heating chamber.

[0006] Multiple storage nets are spaced apart along the height direction inside the drying chamber, and the storage nets are used to place items to be dried;

[0007] The heating chamber is equipped with a blower and a heating element. The heating element is located below the blower. The blower blows air downwards and forms hot air after passing through the heating element.

[0008] An installation opening is provided on the side wall of the housing at a position lower than the lower end of the vertical partition. An air intake fan is provided at the installation opening. The air intake fan is used to introduce dry fresh air and mix it with the hot air. An exhaust port is provided on the side wall of the housing at a position higher than the upper end of the vertical partition.

[0009] As a preferred solution for a household food dryer, the exhaust port is equipped with louvers.

[0010] As a preferred embodiment of a household food dryer, the cabinet has an openable door, and the vertical partition is parallel to the door.

[0011] As a preferred embodiment of a household food dryer, the cabinet has a back panel that faces the door, vertical partitions are arranged parallel to and spaced apart from the back panel, and both the exhaust port and the mounting port are located on the back panel.

[0012] As a preferred option for a household food dryer, the back panel is equipped with an access door.

[0013] As a preferred option for a household food dryer, the storage net can be pulled out and installed inside the drying chamber.

[0014] As a preferred embodiment of a household food dryer, the opposite side walls of the housing are provided with multiple shelf strips spaced apart along the height direction, and each of the storage nets can be placed on two opposite shelf strips.

[0015] As a preferred embodiment of a household food dryer, the heating element includes a heating resistance wire.

[0016] As a preferred embodiment of a household food dryer, it also includes a control panel located outside the housing, which is electrically connected to the blower, heating element, and air inlet fan.

[0017] As a preferred option for a household food dryer, a humidity sensor is also included, which is installed inside the chamber to detect the humidity inside the chamber.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model provides a household food dryer. A blower circulates air through a heating element, creating hot air with low humidity and high temperature. An intake fan draws dry air from outside the chamber, mixing it with the upward-blown hot air to dry the food. The air at the top decreases in temperature and increases in humidity. Simultaneously, the intake fan draws air into the chamber, while some of the high-humidity air at the top is exhausted through the exhaust port, maintaining a suitable overall humidity level inside the chamber. A portion of the air circulates within the chamber via the blower to fully utilize the remaining heat; thus, the air circulated by the blower is the hot air inside the chamber, improving overall drying efficiency. During the air circulation within the chamber, hot air flows from top to bottom through the heating chamber of the vertical partition. Under the effect of thermal radiation, it heats and insulates the drying chamber, while also isolating moisture, thus improving drying effect and efficiency. This household food dryer, with its side-mounted air supply fan and heating elements, facilitates maintenance and replacement. It has sufficient space to accommodate the heating elements, allowing for a larger overall volume and improved heating effect and drying efficiency. Furthermore, it effectively saves vertical space, maximizing the placement of numerous storage nets along the vertical direction, resulting in high space utilization. Attached Figure Description

[0032] like Figures 1 to 5As shown, this embodiment provides a household food dryer, which includes a housing 1. A vertical partition 2 is installed inside the housing 1. The upper and lower ends of the vertical partition 2 are spaced apart from the top and bottom walls of the housing 1, respectively. The vertical partition 2 divides the interior space of the housing 1 into a communicating drying chamber 100 and a heating chamber 200. That is, along the height direction of the housing 1, the interior space of the housing 1 is divided into an upper layer, a middle layer, and a lower layer. A vertical partition is installed in the middle layer, dividing the middle layer space into the drying chamber 100 and the heating chamber 200. The drying chamber 100 is arranged along its height... Multiple storage nets 3 are spaced apart and used to place items to be dried, such as mushrooms, fruits, and vegetables. The heating chamber 200 is equipped with a blower 4 and a heating element 5. The heating element 5 is located below the blower 4. The blower 4 blows air downwards and forms hot air after passing through the heating element 5. An installation port is provided on the side wall of the box 1 below the lower end of the vertical partition 2. An air inlet fan 6 is provided at the installation port. The air inlet fan 6 is used to introduce fresh air for drying and mix with the hot air. An exhaust port is provided on the side wall of the box 1 above the upper end of the vertical partition 2. The air supply fan 4 circulates air through the heating element 5, forming hot air with low humidity and high temperature. The air intake fan 6 introduces dry air from outside the chamber 1 into the lower space inside the chamber 1, where it mixes with the hot air blowing upwards and rises in the drying chamber 100 to dry the items. As the air rises to the upper space inside the chamber 1, the temperature decreases and the humidity increases. While the air intake fan 6 draws air into the chamber 1, some of the high-humidity air at the top of the chamber 1, i.e., the upper space, is discharged through the exhaust port, maintaining a suitable overall humidity inside the chamber 1. Some of the air is circulated inside the chamber 1 by the air supply fan 4 to fully utilize the remaining heat. In other words, the air circulated by the air supply fan 4 is the hot air inside the chamber 1, which helps to improve the overall drying efficiency. During the air circulation process inside the housing 1, when the hot air flows from top to bottom in the heating chamber 200 of the vertical partition 2, it can heat and keep the drying chamber 100 warm under the action of heat radiation, and also isolate moisture, thereby improving the drying effect and efficiency. This household food dryer, through the side-arranged air supply fan 4 and heating element 5, is convenient for maintenance and replacement, and has sufficient space to arrange the heating element 5, so that the overall volume of the heating element 5 can be arranged to be larger, improving the heating effect and drying efficiency. It can also effectively save height space, and as many shelves 3 as possible can be arranged in the height direction, with a high effective space utilization rate.

[0033] In this embodiment, as Figure 2 As shown, the exhaust port is equipped with louvers 7, which facilitates operation and allows the opening and closing size of louvers 7 to be controlled as needed to control the air exhaust rate inside the housing 1.

[0034] Specifically, the chamber 1 has an openable door 11, and a vertical partition 2 is directly opposite and parallel to the door 11. That is, after opening the door 11, the items to be dried can be placed or taken out from the front, and the heating element 5 is hidden behind the vertical partition 2, ensuring the neatness and aesthetics of the interior after the door 11 is opened.

[0035] Preferably, the door 11 is provided with a handle 10 to facilitate opening and closing the door 11.

[0036] More specifically, the chamber 1 has a back panel 12, which faces the door 11. Vertical partitions 2 are arranged parallel to and spaced apart from the back panel 12. Both the exhaust port and the mounting port are located on the back panel 12. The blower 4 blows air downwards, which is heated by the heating element 5 to form hot air. The hot air descends and merges with the dry air introduced by the inlet blower 6. The inlet blower 6 blows air towards the door 11, that is, the mixed air of dry air and hot air is sent to the bottom of the drying chamber 100. The hot air rises to dry the items to be dried in the drying chamber 100. While the inlet blower 6 continues to blow air in, part of the air in the upper space of the chamber 1 is squeezed out of the chamber 1, that is, discharged from the exhaust port. The other part is circulated by the blower 4. In this way, the air forms an internal circulation and an external circulation within the chamber 1, effectively drying the items to be dried.

[0037] To facilitate the inspection and replacement of the air supply fan 4 and the heating element 5, an inspection door is provided on the back panel 12. When it is necessary to inspect or replace the air supply fan 4 and the heating element 5, simply open the inspection door.

[0038] In this embodiment, the heating element 5 includes heating resistance wires. One or more sets of heating resistance wires are arranged in a coil along the height direction of the box 1 in the heating chamber 200. The heating resistance wires are heated by power supply to heat the air. The arrangement of the heating element 5 along the height direction of the box 1 results in a higher and more uniform temperature in the drying chamber 100, which is beneficial to improving drying efficiency, especially the drying effect of the items to be dried at the top.

[0039] Furthermore, the storage net 3 can be pulled out and installed inside the drying chamber 100, which facilitates cleaning of the storage net 3 and collection of the dried items. That is, after drying, the storage net 3 can be pulled out directly and used as a tray to support the items to be dried, or the dried items on the storage net 3 can be poured directly into the collection box or collection bag, saving collection time. At the same time, the items to be dried can be placed on the storage net 3 first and then the storage net 3 can be pushed into the drying chamber 100, avoiding the user's effort when placing items to be dried on the upper or deeper layers, thus improving the user experience.

[0040] For example, such as Figure 3 and Figure 4As shown, multiple shelf strips 8 are spaced apart along the height direction on both opposite side walls of the box 1, and each storage net 3 can be placed on two opposite shelf strips 8. The above structure is simple, the manufacturing process is simple, and the cost is low.

[0041] Furthermore, such as Figure 1 As shown, this household food dryer also includes a control panel 9, which is located outside the housing 1 and is electrically connected to the supply fan 4, heating element 5, and intake fan 6. The air speeds of the supply fan 4 and intake fan 6 are adjustable; different speeds can be achieved by adjusting different settings. The heating element 5 has adjustable heating settings, such as low, medium, and high, to meet different usage needs. By operating the control panel 9, the start / stop and settings of the supply fan 4, heating element 5, and intake fan 6 can be adjusted, making it convenient, quick, and highly automated.

[0042] Preferably, the household food dryer also includes a humidity sensor, which is installed inside the cabinet 1, specifically in the upper space of the cabinet 1, to detect the humidity inside the cabinet 1. By obtaining the detection value of the humidity sensor, the humidity inside the cabinet 1 can be known in real time. For example, the opening of the louvers 7 or the speed of the air supply fan 4, the air intake fan 6, and the heating element 5 can be adjusted according to the humidity.

[0043] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
