Description

TECHNICAL FIELD

[0001] The application relates to the technical field of hot tank connection, and in particular to a connecting structure of a hot tank and a support and a water supply device. BACKGROUND

[0002] In the field of drinking water equipment, a hot tank plays a vital role. It is not only a container for storing hot water, but also a core component for heating and maintaining water temperature. The performance of the hot tank, including its heating efficiency, heat preservation performance and durability, is directly related to the overall energy efficiency and user experience of the drinking water equipment. However, in the prior art, the connection mode of the hot tank and the support has become a bottleneck restricting the performance improvement of the equipment. Specifically, the hot tank and the support are in close contact, and the direct contact area is too large, resulting in increased heat loss. Heat conduction is the basic way of heat transfer through solid materials. When two objects are in direct contact, heat will be transferred from the object with a higher temperature to the object with a lower temperature. At the contact surface of the hot tank and the support, a large amount of heat will be generated during the heating process of the hot tank. This heat will be quickly transferred to the surrounding environment through the support, causing unnecessary heat loss. This heat loss not only increases the energy consumption of the equipment and reduces the energy utilization efficiency, but also may have a negative impact on the long-term operation of the equipment. On the one hand, in order to make up for the heat loss, the equipment needs to consume more electric energy to heat and maintain the temperature of the hot water, which will significantly increase the energy consumption. On the other hand, heat loss will also accelerate the aging process of components such as the hot tank and the support, shorten the service life of the equipment, and increase the maintenance cost of the user.

[0021] According to the technical scheme, the tank body is a core component of the drinking water equipment, which is mainly composed of a square tank cylinder and two end covers. The square tank cylinder, as the main part of the heat tank body, is usually made of high-strength and corrosion-resistant materials to ensure that it can withstand high-temperature and high-pressure working environments.

DETAILED DESCRIPTION

[0044] ​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0045] The present embodiment proposes a connection structure of a heat tank and a support, as shown in Figures 1 to 9 The connection structure includes a heat tank body 1, a connecting piece 3 and a mounting rack 2, the heat tank body 1 is located in the mounting rack 2; the connecting piece 3 is located between the heat tank body 1 and the mounting rack 2, and the heat tank body 1 is connected with the mounting rack 2 through the connecting piece 3; the connecting piece 3 has a hollow structure and the hollow opening extends at least to one end or / and the circumferential side close to the heat tank body 1; the design of the hollow structure can reduce the material usage of the connecting piece 3 itself, thereby reducing the contact area with the heat tank body 1 and improving the heat insulation effect. Different application scenarios and installation environments may require the connecting piece 3 to be located at different positions of the heat tank body 1; for example, in some cases, it may be necessary to install the connecting piece 3 at one end or both ends of the heat tank body 1 to fix the heat tank body 1 on the mounting rack 2; while in other cases, it may be necessary to distribute the connecting piece 3 on the circumferential side of the heat tank body 1 to provide more uniform support and stability.

[0046] As a preferred embodiment, the connecting piece 3 is a heat insulation piece. Among them, the heat insulation piece includes one or more of non-metal heat insulation piece, metal heat insulation piece and composite heat insulation piece.

[0047] The non-metal heat insulation piece is made of non-metal heat insulation material, such as rubber pad, rubber sleeve, etc. The non-metal heat insulation piece is made of materials such as ceramic fiber, rock wool, glass wool, expanded perlite and aluminum silicate fiber, etc. These materials have good high temperature resistance, low thermal conductivity and excellent heat preservation and insulation performance. The metal heat insulation piece is made of metal heat insulation material, such as aluminized steel plate and stainless steel heat insulation plate, etc. In addition to having heat insulation, corrosion resistance and high temperature resistance, they also have certain strength and rigidity. The composite heat insulation piece is made of composite heat insulation material, such as aerogel heat insulation material, vacuum heat insulation plate and multi-layer composite heat insulation material, etc. These materials can have extremely low thermal conductivity and excellent heat insulation performance after processing.

[0048] Of course, in order to further improve the heat insulation effect between the heat tank body 1 and the connecting piece 3, a coating or protective layer with heat insulation effect can also be coated or covered between the heat tank body 1 and the connecting piece 3 to block or reduce heat transfer and maintain the stability of the internal temperature of the heat tank body 1.

[0049] As a possible embodiment, the connecting piece 3 includes a first connecting piece 31 ，The first connecting member 31 is installed on the heat tank body 1, and can be fixed or detachably installed on the heat tank body 1. Specifically, the first connecting member 31 can be detachably installed on the heat tank body 1 by means of threaded connection, buckle connection, quick-release buckle or the like, and can be fixedly connected to the heat tank body 1 by means of welding.

The first connecting member 31 and the second connecting member 32 are fixed at the top and bottom of the heat tank body 1, respectively, to ensure the stability and balance of the heat tank body 1 in the mounting rack 2. The design of the first connecting member 31 and the second connecting member 32 reduces the direct contact area between the heat tank body 1 and the mounting rack 2, thereby reducing the efficiency of heat transfer through solid materials and unnecessary heat loss, which helps to improve the heat preservation performance of the heat tank body 1 and reduce energy consumption. At the same time, the connection between the heat tank body 1 and the mounting rack 2 has a certain degree of firmness, which can effectively prevent the heat tank body 1 from shaking or moving during operation.

This threaded connection not only provides reliable connection strength, but also makes the installation and disassembly process simple and fast. By rotating the first bolt 312, the connection or separation can be easily realized, and the structure is compact. Of course, the through hole 3111 and the thread design on the connecting block 311 have certain adaptability, which can be adjusted according to the actual size of the heat tank body 1 and the mounting rack 2, so that the first connecting piece 31 can be applied to the connection structure of heat tanks and supports of different specifications and models. The connection mode of the first connecting piece 31 reduces the direct contact area between the heat tank body 1 and the mounting rack 2, thereby reducing the efficiency of heat transfer through solid materials, which helps to reduce heat loss and improve the heat preservation performance of the heat tank.
