Technical Field

[0001] This utility model relates to the field of catering equipment technology, and in particular to a double-door food warming cart. Background Technology

[0002] In the catering service industry, whether it is banquet catering in large hotels or centralized catering in school and factory canteens, keeping food at a suitable temperature for diners is a crucial step. Traditional heat preservation equipment often cannot meet the different heat preservation requirements of dry and wet dishes at the same time, resulting in a decline in the quality of the dishes during long-term supply and affecting the dining experience of diners. Therefore, a double-door food warming cart is needed.

[0003] Chinese Patent Publication No. CN108209435A discloses a food warming device. The technical problem this invention aims to solve is to provide a multifunctional food warming device. To address this problem, the aforementioned patent document provides a food warming device comprising a frame, etc.; a dining table is located on the lower inner side of the frame; a transmission device is located on the upper inner side of the frame; a lifting device is connected below the transmission device; a warming cover is located in the middle of the frame; and the upper part of the warming cover is connected to the lifting device. This patent document achieves the function of continuously keeping food warm, preserving the original flavor of the food. Furthermore, this patent document features good warming effect, convenient operation, simple manufacturing, low manufacturing cost, and ease of widespread adoption.

[0004] However, the above-mentioned patent documents still have the following defects in practice;

[0005] While the aforementioned patented equipment can keep food warm, it cannot keep different types of food warm simultaneously. It cannot precisely control the water temperature and maintain uniform water circulation for wet dishes such as soups, stews, and hot broths, which may cause soups to cool and congeal, resulting in a deterioration in texture due to temperature changes and nutrient loss. Furthermore, it cannot keep multiple dishes warm at the same time, making it inefficient for large-scale catering events or group meal scenarios where large quantities of food cannot be quickly placed into the warming mechanism or the warming process cannot be completed in one go, thus reducing service efficiency.

The wet heat preservation mechanism 6 keeps the dishes placed in the placement mechanism 1 4 wet and warm. The placement mechanism 2 5 and placement mechanism 1 4 can keep several dishes warm at the same time.

[0029] Specifically, in order to achieve the purpose of keeping the food inside the placement mechanism 4 moist and warm, refer to Figure 2In this scheme, the placement mechanism 4 includes several support plates 42 and several spray heads 45. The support plates 42 are rectangularly distributed and fixedly connected to the right side of the inner cavity of the box 1. The spray heads 45 are rectangularly distributed and fixedly connected to the right side of the rear wall of the inner cavity of the box 1. The upper middle part of the support plates 42 is fixedly connected to the placement plate 41. The upper end of the support plates 42 is provided with a guide groove 43. The right side of the rear wall of the inner surface of the guide groove 43 is provided with a through hole 44.

[0030] Furthermore, several spray heads 45 are located on the upper part of the same side placement plate 41, the upper ends of several placement plates 41 are all inclined, and the rear ends of several through holes 44 penetrate the rear part of the inner cavity of the box body 1 and extend to the outside.

[0031] In the above process, after opening the double door 8, the food is placed on the upper part of the placement plate 41. Then, the internal drive structure of the wet heat preservation mechanism 6 is activated so that the spray head 45 can spray hot water mist to keep the food warm. Then, the excess water mist sprayed by the spray head 45 will flow from the inclined surface of the upper surface of the placement plate 41 into the guide groove 43, and then flow back into the wet heat preservation mechanism 6 through the through hole 44.

[0032] Specifically, in order to achieve the goal of using the spray nozzle 45 to spray hot mist to keep the food warm, refer to... Figure 2 and Figure 3 In this scheme, the wet insulation mechanism 6 includes a second long tube 64 and a receiving cavity 65.

[0034] In the above process, the heating water tank 61 is first filled with water, then the heating water tank 61 is started to heat the water inside, and then the water pump 62 is started to pump the hot water inside the heating water tank 61 into the inner cavity of the spray head 45 through the first long pipe 63, and then sprayed out from the spray head 45. The water flowing out from the through hole 44 will flow back into the heating water tank 61 through the second long pipe 64 to be heated, thereby achieving the purpose of wet heat preservation.

[0035] The specific installation method, circuit connection method, and control method of the heating water tank 61 used above are all conventional designs, which only need to be able to heat the water source to 60 to 80 degrees Celsius. This utility model will not elaborate further.
